t s ii I Executive Summary Cardiovascular disease is the leading cause of death both nationally, and in Arizona. The main components of cardiovascular disease are coronary heart disease, congestive heart failure, and stroke. Each year, nearly 1,000,000 Americans die of cardiovascular disease nationwide. In Arizona, heart disease and stroke claim the lives of more than 13,000 people each year. Efforts to reduce the large number of lives lost to heart disease and stroke led to the Healthy People 2010 initiative, that established specific goals to target heart disease, stroke, blood pressure and blood cholesterol. The goal for heart disease is to decrease the mortality rate to less than 166 deaths per 100,000 population and the goal for stroke is to decrease the mortality to below 48 deaths per 100,000 population. As a whole, the Arizona population has met some of these goals, yet there are some groups in the population that are still far from meeting the HP2010 goal. This document provides a snapshot of the current cardiovascular disease burden in Arizona. It identifies the mortality rates, prevalence rates, and hospitalization rates and estimated costs for cardiovascular disease risk factors and diseases. This document seeks to identify trends in disease over time; it also seeks to identify disparities in disease burden so that resources can be appropriately allocated. Many sources were used to collect the data, each with their own limitations. Despite these limitations, this document provides the most comprehensive and current data for the state with regard to burden of heart diseases and stroke. Similar to other states, Arizona has an aging population. According to the Arizona Department of Economic Services, approximately 14% of the 2007 population in Arizona is age 65 and older. By 2020 those over the age of 65 are expected to comprise 17.6% of the population and by 2055 they are expected to comprise 21.3% of the population (figures 1,2, & 3). Since age is one of the primary risk factors for developing cardiovascular disease, the burden will increase as the population ages.

If better prevention strategies for cardiovascular disease are not implemented within the aging population of Arizona, the healthcare costs of treating heart disease and stroke will continue to increase. Additionally, Arizona is the 6th largest land mass in the US, and is divided into 15 large counties. Many of these counties are still considered frontier areas. With the exception of the 3 major metropolitan areas, Phoenix, Tucson, and Yuma, many people have to drive hundreds of miles to receive specialized care. The counties with the highest rates of coronary heart disease are Cochise, Maricopa and Mohave Counties. The counties that have the highest mortality rate from stroke are Greenlee, Navajo and Yavapai Counties. Through this document, the following disparities were found: • African American women suffer the highest mortality rates for coronary heart disease and stroke in Arizona, compared to men or women of any race. • Among males, Hispanic men had the highest mortality rates for congestive heart failure and stroke, whereas African American men had the highest mortality rate for coronary heart disease. • While stroke mortality rates are decreasing among most groups, they are rising among Arizona’s Asian population. • Asian and Hispanic females have the highest mortality rates from heart failure compared to other racial/ethnic groups and genders. • American Indians have the highest percentage of premature deaths from all forms of cardiovascular disease compared to other racial/ethnic groups. This document will be used in conjunction with the Arizona Cardiovascular Disease State Plan to determine priority populations and develop strategies to provide care for CVD patients with the greatest need. Through the collaboration with other organizations, it will be possible to have a positive impact on the burden of CVD in Arizona. Executive Summary  II Methodology Crude rates The crude incidence rate reports the number of people per 100,000 population per year who have been newly diagnosed with the disease of interest. The crude rate has the advantage that it is a simple, easily calculated measure that gives a broad picture of the extent of new disease in a particular area in a particular time period. It does not reflect the variation in the risk of disease due to factors, such as age, which also affect risk. The development of most diseases and cancer especially, is highly related to age: the older you get, the higher your chance of developing the disease. This means that a population with a higher proportion of older people will have a higher crude rate even if the risk of disease in the population is the same as another population with a lower proportion of older people. Information from: http://www.trentcancer.prestel.co.uk/statexpl.htm Crude Mortality Rates Like the crude incidence rate, the crude mortality rate is not adjusted to age distribution of a standard population. It simply counts the number of deaths that have occurred and is divided by the number of persons in the population, then expressed per 100,000 persons. Age-Adjustment Age adjustment is used to compare risks of two or more populations at one point in time or one population at two or more points in time. Age-adjusted rates are computed by the direct method by applying age-specific rates in a population of interest to a standardized age distribution, in order to eliminate differences in observed rates that result from age differences in population composition. Age-adjusted rates should be viewed as relative indexes rather than actual measures of risk. Rates have been adjusted according to the US 2000 Standard population to more accurately reflect the US population as it is now and to allow comparisons. Arizona figures are calculated and computed using a standard population in order for it to be comparable to the US as well as other rates using the US 2000 standard population. Information from: http://www.cdc.gov/nchs/datawh/nchsdefs/ageadjustment.htm Methodology  Hospitalization Calculations Hospital data was calculated using hospital inpatient discharges and emergency department visits from the Arizona Health Status and Vital Statistics: 2005. An inpatient discharge occurs when a person who was admitted to a hospital leaves that hospital. A person who has been hospitalized more than once in a given calendar year will be counted multiple times as a discharge and included more than once in the hospital inpatient discharge data set; thus, the statistics in this report are for discharges, not persons (ADHS Vital Statistics, 2005). For the purposes of this document unadjusted rates were obtained by taking the number of discharges or emergency visits by the reference population per 10,000. For example, the number of discharges by racial/ethnic group was divided by the reference population (American Indian, White, African American…) for the same year. The figure or rate was then calculated per 10,000 population. Race/Ethnicity The racial/ethnic groups that are discussed throughout the text have been summarized as follows: White (non, Hispanic) – includes people having origins in any of the original peoples of Europe, the Middle East, or North Africa. African American – includes people having origins in any of the black racial groups of Africa. The two terms have been used interchangeably throughout the document. American Indians – includes American Indians and Alaska Natives (AI/ANs) and are people having origins in any of the original peoples of North and South America (including Central America), and who maintain tribal affiliation or community attachment. Asians – includes both the Asians/Pacific Islanders and are people having origins in any of the aboriginal peoples of the Far East, Southeast Asia, the Indian subcontinent, Hawaii, Guam, Samoa, or other Pacific Islands, even if they do not live in the Pacific Islands. Hispanics – people of Cuban, Mexican, Puerto Rican, South or Central-American, or other Spanish culture or origin, regardless of race. Information from: CDC according to http://www.cdc.gov/omhd/ Life Expectancy Median age at death and premature mortality calculations are according to the 2004 US life expectancy of 77.9 years. Notes: *Rates per 100,000 are age-adjusted to the 2000 U.S. standard population. **Based on expected years of life for all US residents, which is 77.9 years in 2004 Methodology  III L i s t o f F i g

coronary heart disease (CHD), heart attack, stroke, high blood pressure, congestive heart failure (CHF) and congenital heart disease. These diseases can be interrelated and usually have the same risk factors (see Appendix A). CVD has been the leading cause of death every year since the early 1900’s, with the exception of 1918 where influenza was the leading cause of death. Despite the increase in scientific knowledge and health awareness that occurred since that time, CVD continues to be the most prevalent health problem in the US, surpassing other diseases such as diabetes and all forms of cancer combined. According to the Centers for Disease Control and Prevention (CDC), approximately 950,000 Americans die from CVD each year, which is one death every 33 seconds (http://www.cdc.gov/, accessed July 18, 2007). Additionally, approximately 31 million Americans, or one-fourth of the US population, are currently living with some form of CVD. Arizona has the 6th largest land mass in the United States, and is comprised of 15 counties total: Apache, Cochise, Coconino, Gila, Graham, Greenlee, La Paz, Maricopa, Mohave, Navajo, Pima, Pinal, Santa Cruz, Yavapai and Yuma. Some of these counties still have areas that qualify as frontier areas. According to the 2006 census population estimates, the population in Arizona is over 6.1 million individuals. Approximately 76% of the population lives in Maricopa or Pima Counties, leaving 24% of the Arizona population living in rural parts of the state. (http://factfinder.census.gov/servlet/ACSSAFFFacts?_event=&geo_id=04000US04&_geoContext =01000US%7C04000US04&_street=&_county=&_cityTown=&_state=04000US04&_zip=&_lang=en&_sse= on&ActiveGeoDiv=geoSelect&_useEV=&pctxt=fph&pgsl=040&_submenuId=factsheet_1&ds_name=null&_ ci_nbr=null&qr_name=null®=null%3Anull&_keyword=&_industry=, 2005) According to the 2005 Census data, the median age for the Arizona population is 34.5 and 12.1 percent of the population is over the age of 65. Approximately 3 percent of the population is African American, 4.7 percent is American Indian, 2.2 percent of the population is Asian, and 76.2 percent of the population is White. The Hispanic population comprises 28.6 percent of the population as well. Arizona is home to 21 separate sovereign American Indian nations located on 24 reservations throughout Arizona. The American Indian population comprised approximately five percent of the population. This document defines the burden of CVD in Arizona and identifies which populations are at most risk. This document focuses on coronary heart disease, congestive heart failure and cerebrovascular disease (which for the purposes of this document is referred to as stroke). This document, when used in conjunction with the Arizona Cardiovascular Disease State Plan, will help guide the actions and interventions of the state and local health departments and the communities and organizations that conduct activities in and around CVD. Introduction 14 CHAPTER 1 Cardiovascular Disease Mortality, Prevalence, and Hospitalizations 15 Cardiovascular Disease In Arizona, diseases of the heart are the first and stroke is the fourth leading causes of death, respectively. In the United States (US), diseases of the heart and stroke are the first and third leading causes of death (table 1). 1 TA B L E Top 10 Causes of Death, Arizona and US, 2004 Arizona Rank 1 Cause of Death Diseases of the Heart Arizona Age Adjusted Rate US Age Adjusted Rate US Rank 186.7 217.0 1 2 Cancer 164.7 185.8 2 3 Unintentional Injuries 46.0 37.7 5 4 Stroke 43.6 50.0 3 41.9 41.1 4 31.3 21.8 7 5 6 Chronic Lower Respiratory Disease Alzheimer's Disease 7 Diabetes Mellitus 20.7 24.5 6 8 Influenza and Pneumonia 20.1 19.8 8 9 Suicide 14.9 10.9 11 10 Chronic Liver Disease and Cirrhosis 11.1 9.0 12 Source: Arizona Vital Statistics 2004, CDC Compressed Mortality File Source: Arizona Vital Statistics 2004, CDC Compressed Mortality File These chronic diseases cause major disability and contribute to high costs associated with health care and hospitalizations. CVD Mortality From 1980 to 2004, the CVD mortality trend in Arizona has decreased by almost 50 percent (figure 4). Despite this marked decrease, CVD still remains the leading cause of death in both the US and Arizona. In Arizona, CVD accounts for roughly 40 percent of the leading causes of death of which 20 percent is due to CHD, six percent is due to stroke and 14 percent from other diseases of the heart such as heart failure (figure 5).

The median ages for CVD deaths are 75.8 years for Hispanics, 72.1 years for African Americans, 69.6 years for American Indians, and 79.1 years for Asians (see figure 16). Racial and ethnic minorities have higher rates of premature death from CVD than the White population. About 68 percent of American Indians and about 64 percent of African Americans die prematurely compared to only 37 percent for Whites (figure 17).

While mortality rates trended down for all groups from 1980 – 2004, there were still significant differences in the mortality impact on racial/ethnic minorities in Arizona. African Americans had the highest CVD death rate throughout that time period, which was at least 25 percent higher than Whites by 2004 (figures 18, 19 and 20).

Although the lowest mortality rate occurs in American Indians, it is similar to the other mortality rates and not much lower than the average (see figure 21). When comparing the leading causes of death within each racial/ethnic group, diseases of the heart far exceed any other disease mortality rate. Stroke is the third leading cause of death for African Americans and Asians and fourth for American Indians, Hispanics and Whites (figure 23).

F I G U R E 26 Chapter 1 Cardiovascular Disease Age-Adjusted Mortality Rate per 100,000 by County, Arizona, 1999-2004 28 CVD Prevalence According to the 2006 Behavior Risk Factor Surveillance System (BRFSS), a self-reported questionnaire administered to Arizona adults, the percentage of those affected by at least one or more CVD was about eight percent. The BRFSS included three questions related to CVD: • Has a doctor, nurse, or other health care professional ever told you that you had a heart attack, also called a myocardial infarction? • Has a doctor, nurse or other health care professional ever told you that you had angina or coronary heart disease? • Has a doctor, nurse, or other health care professional ever told you that you had a stroke? In Arizona, males are more likely to have suffered a heart attack, angina, and/or stroke than females. White Arizonans were more likely than other race/ethnic groups to report having experienced at least one type of CVD. Increasing age is a major risk factor for CVD. Between the age groups 55-65 and 65+ the CVD prevalence increased from approximately 11 percent to 28 percent. Socioeconomic status is associated with CVD prevalence. Those with a household income of $35,000 or less reported having more CVD-related health conditions than those from households with incomes greater than $35,000. Persons with household incomes of less than $15,000 were four times more likely to have CVD than persons with a household income of more than $75,000 (figure 27).

Those who have achieved a higher level of education are less likely to report having CVD. A higher number of those who did not complete a high school education reported having more CVD related health conditions than those who had some post high school or college graduate education. Coronary Heart Disease (CHD) Coronary heart disease, previously referred to as coronary artery disease, occurs when the arteries that supply blood to the heart muscles become hardened and narrowed from a buildup of plaque on the inner walls. (http://www.nhlbi.nih.gov/, 2007) Plaque is comprised of fat, cholesterol, calcium, and other substances from the blood. Plaque buildup usually begins in childhood. As plaque buildup occurs, there are three possible outcomes: • The arteries narrow and reduce the amount of blood and oxygen that reach the heart muscle. • The plaque completely blocks the arteries and stops the flow of blood to the heart muscle. • Blood clots form and can possibly block the arteries that supply blood to the heart muscle. As plaque continues to buildup within the arteries, the coronary arteries narrow, thus restricting blood flow. Eventually blood flow to the heart muscle is reduced compromising the supply of oxygen necessary for normal function. This can lead to other cardiovascular problems such as angina or heart attacks. CHD Mortality Similar to the overall trend in deaths from CVD, deaths from coronary heart disease (CHD) have decreased by half since 1980 (figure 28).

Although the overall state rate is below the HP2010 goal of 166 deaths per 100,000, the rates are not uniform and several counties have higher rates and do not meet this goal (figure 29).

American Indians in Arizona have a median age of death from CHD of 70.6 years, which is at least 10 years younger than Whites in Arizona. (81.2 years). Over half of Figure 36: Median Age at Death for Coronary Heart Disease by Race/Ethnicity, Arizona, 2005 premature deaths from CHD in Arizona occur among the ethnic minority groups in the state (figure 36 and 37).

More males than females reported having experienced CHD, and more Whites have experienced CHD compared to Hispanics. Arizona adults suffer more from CHD as age increases. About three percent of those between the ages of 35-44 compared to approximately 22 percent of those 55-64 years old reported having CHD. The prevalence of CHD was inversely related to education; those who had more education (post high school and college graduate) were less likely to report having CHD than those who had less than a high school education. There were also significant disparities among different income groups. As household income increases, the prevalence of CHD decreases. The largest difference occurs between those with a household income less than $15,000 compared to those with a household income greater than or equal to $75,000 (14 percent vs. 3 percent). As with all cardiovascular diseases, CHD poses a heavier burden on populations with lower levels of education and household incomes (figure 38).

This disease progresses over time as the pumping action of the heart grows weaker. It can affect either side of the heart at one time or both sides of the heart simultaneously. This weakening of the heart’s pumping can cause blood and fluid to “back up” into the lungs, buildup of fluid in the feet, ankles and legs, and tiredness and/or shortness of breath. The primary causes of CHF are CHD, high blood pressure and diabetes. CHD is the leading underlying cause for CHF in the US. (http://www.nhlbi.nih.gov/health/dci/Diseases/Hf/HF_ Causes.html, 2007) CHF Mortality The overall CHF mortality rate from 1980 to 2004 has been unsteady in Arizona, with the highest rate in 1992 at 22.4 and the lowest rate in 1995 at 11.6.

Although the difference is small, more males (23 per 10,000) than females (18.7 per 10,000) were diagnosed with CHF and more African Americans (36.7 per 10,000) were diagnosed with CHF than any other racial/ethnic groups. The group with the lowest crude rate was the American Indians (7.7 per 10,000). As with many of the other cardiovascular diseases, CHF increased with age and was a more common discharge diagnosis in older age groups compared to younger age groups.

A stroke occurs when a blood vessel in the brain that carries oxygen and nutrients is either blocked by a clot or plaque, or ruptures. Similar to a heart attack, when this occurs the affected area of the brain cannot get the oxygen and nutrients that it needs and begins to die. There are two different forms of a stroke: ischemic and hemorrhagic. Ischemic strokes occur as a result of an obstruction within a blood vessel supplying blood to the brain. The underlying condition for this type of obstructions is the development of fatty deposits lining the vessel walls. Hemorrhagic stroke occurs results from a weakened blood vessel ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surround brain tissue. Ischemic strokes account for 83 percent and hemorrhagic strokes make up 17 percent of all strokes (http://www.strokeassociation.org/presenter.jhtml?identifie r=1014#Ischemic, 2007) Stroke Mortality Overall stroke mortality decreased by almost half in the US from 1980-2004. The decrease in Arizona has been almost as steep (figure 50).

However, the death rate among Asians has rapidly increased since 2003. In 2000, Asians had the lowest mortality rate, but in 2005 the rate is nearly the highest in Arizona, almost equal to the African American mortality rate. The most significant decrease in stroke mortality has been among American Indians, but that decrease has appeared to slow in 2004. Whites have also seen a decline in stroke mortality rates in Arizona, decreasing by 25 percent from 2000 to 2005. Among Hispanics, the death rate from stroke increased between 2000 and 2004, but decreased from 2004 to 2005 (figure 57).

According to the results of the questionnaire, approximately three percent of Arizona adults had a stroke. More Whites reported having had a stroke than Hispanics or other races. Strokes occur more often in those who are older, with a marked increase in age groups 55-64 and 65 and older. Although the literature has not found an association between stroke prevalence and education, our data suggests that those with more education were less likely to have a stroke. There is a distinction between those who identified themselves as belonging to a household with an income of less than $15,000 compared to households that earn over $75,000. Individuals with lower household incomes are more likely to have experienced a stroke than those who have household incomes of more than $75,000. Characteristics that seem to be associated with having a stroke are race, age, and income (figure 61).

TO TA L Ma le Fe ma le 0 Hospitalizations Source: BRFSS 2006 There are nearly twice as many discharges for CHD than there are for strokes, and hospitalizations for stroke outnumber those for CHF. The number of discharges per 10,000 for a primary diagnosis of CVD shows that more males than females were discharged with CVD in Arizona during 2005. This pattern repeats itself for diseases of the heart, CHD, and CHF. Although the figures are small, the rate of hospitalization for stroke per 10,000, is higher for females (28.6) than males (26.5) (shown again for reference, figure 47).

From age groups 45-64 and age 65 and older, mortality rates increase at least 3 times. Thus, age is a risk factor for being discharged with a CVD related condition (shown again for reference figure 48).

Modifying these risk factors, either by lifestyle changes or medically, has been shown to have an impact on the prevalence of CVD. Additionally, treating the risk factors also has decreased the recurrence of CVD. Regular exercise, improved nutrition, and tobacco cessation can result in lower blood pressure and cholesterol as well as reduce obesity which in turn leads to a lower risk of developing or worsening CVD. High Blood Pressure (Hypertension) High blood pressure is a risk factor for heart disease, stroke and other medical conditions. As many as a third are unaware that they have high blood pressure, and those with the diagnosis may not feel badly and as a result do not take their medications, hence the name “silent killer.” Risk factors that may contribute or exacerbate high blood pressure are obesity, eating too much salt, drinking too much alcohol, physical inactivity, and stress. There are risk factors for high blood pressure that are non-modifiable, including race, heredity, and age (http://www. americanheart.org, 2007). It is reported that about one of every three US adults have high blood pressure and that, until age 45, more men have high blood pressure than women. Between the ages of 45-54, the trend for both genders are similar and the trend reverses where more women have high blood pressure than men after the age of 54. More African Americans than Whites are likely to develop high blood pressure. In fact, African Americans in the US have a 50 percent higher prevalence of high blood pressure than Whites (Cooper et al., 2005). High blood pressure can also be hereditary. An individual is more likely to be at risk for developing high blood pressure if it runs in the family. According to results of the BRFSS, 22.3 percent of the adult population in Arizona reported they had high blood pressure in 2005 (figure 64).

This is well above the HP2010 goal of 16 percent. Data from the 2005 BRFSS shows that men and women were equally as likely to report having high blood pressure (22.6 percent vs. 22.1). Additionally, the risk of high blood pressure increased with age. About 13 percent of those who were 35-44 years of age reported they had high blood pressure compared to 22.8 percent who were 55-64 years of age and 52.5 percent of those 65 and older. More Whites (25.3 percent) than Hispanics (14.5 percent) reported having high blood pressure. Although a higher overall percentage of those who belong to lower income families reported having high blood pressure, the difference is more evident between two specific income categories. Those who reported an income of $15,000-24,999 (28.8 percent) had a much higher percentage of being told they had high blood pressure compared to those in the $50,000 or more household income (17.6 percent). There was no overall trend in education except a higher percentage of high blood pressure (25.4 percent) was reported by those who completed high school compared to those who were college graduates (18.7 percent) (table 2).

More specifically, approximately 1/3 to 1/2 of CHD would be prevented with better blood pressure control. Unfortunately, high blood pressure is a condition that more than 90 percent of adults will experience during their lifetime (Wang & Vasan, 2005). High Blood Cholesterol (Hyperlipidemia) Cholesterol is a waxy, fat-like substance found in foods that the body uses to help make Vitamin D, hormones, and substances to aid in digestion and is found in the blood stream and in all body cells (http://www.nhlbi. nih.gov/health/dci, 2006). Cholesterol is obtained in two ways: 1) it is made by the liver; and 2) it comes from animal products such as beef, poultry, eggs, fish, butter, cheese and milk. Foods such as fruits and vegetables do not have cholesterol in them. Individuals with high cholesterol levels often have high levels of cholesterol synthesized by the liver or a high dietary cholesterol intake. There are two forms of cholesterol in the blood. High-density lipoprotein cholesterol (HDL) is considered “good” or protective cholesterol. It helps to extract excess cholesterol from blood vessel walls and transport it back to the liver for elimination through the gastro intestinal tract (Toth, 2005). Low-density lipoprotein cholesterol (LDL) is the other form of cholesterol in the blood and is commonly referred to as “bad” cholesterol. LDL cholesterol collects inside the walls of arteries and contributes to the formation of plaque. The risk of developing CVD increases exponentially as LDL levels rise (Grundy, et.al., 2004). Even in patients with a well controlled LDL cholesterol level below the recommended guidelines, if the HDL level is lower than the recommended level, the risk of developing CVD increases. The risk factors for high cholesterol are smoking, high blood pressure, low HDL cholesterol, family history of early heart disease, and age (men over 45 years and women over 55 years). (http://www.nhlbi.nih.gov/health/public/heart/chol/wyntk.htm#risk, 2005) The following question relating to blood cholesterol was asked on the 2005 BRFSS, “Have you ever been told by a doctor, nurse, or other healthcare professional that you have high blood cholesterol.” The percentage of people who reported having high cholesterol has been increasing in Arizona since 1999. The HP2010 goal is set at 17 percent or less of the adult population having high blood cholesterol. In 2005, the prevalence of high cholesterol in Arizona was nearly double the goal (33.8 percent) (figure 65).

In Arizona, the risk of high cholesterol is associated with increasing age. About 24.8 percent of the respondents ages 35-44 years reported high cholesterol compared to 49.9 percent ages 65 and older. More Whites (36.8 percent) than Hispanics (22.3 percent) reported having high cholesterol. Although 36.1 percent of those in households earning between $15,000-24,999 compared to 29.1 percent of those earning $50,000 or more per household reported high cholesterol, there was no real trend that could be established between income and high cholesterol. Additionally, no real trend could be established for education and high cholesterol. However, those with less than a high school education reported high blood pressure more often than those with a high school diploma or G.E.D. (table 3).

It increases overall well-being and also helps decrease risk of death from CHD, stroke, colon cancer, diabetes, high blood pressure, etc. CDC recommends that adults should participate in at least 30 minutes of moderate physical activity on five or more days each week. HP2010 suggests 20 minutes of vigorous physical activity on three or more days each week. Although there are well known significant health benefits to physical activity, more than half of adults in the US do not get the recommended amount of exercise. Chapter 2 58 The HP2010 objective was to decrease the number of people who do not get enough physical activity (both moderate and vigorous exercises) to 20 percent of the adult respondents. This objective has yet to be achieved. In 2006, 22.3 percent of the adult respondents reported insufficient activity for both moderate and vigorous exercises (figure 66).

Source: Arizona BRFSS, 1994-2004. (Note: From 2003, the percentage represents insufficient activity for both moderate and vigorous exercise). Until 2002 the percentages mean no leisure activity. Several questions from the BRFSS were analyzed to obtain the percentages of Arizona adult respondents who were physically inactive: • Now, thinking about the moderate activities you do in a usual week, do you do moderate activities for at least 10 minutes at a time, such as brisk walking, bicycling, vacuuming, gardening, or anything else that causes some increase in breathing or heart rate? • Now, thinking about the vigorous activities you do in a usual week, do you do vigorous activities for at least 10 minutes at a time, such as running, aerobics, heavy yard work, or anything else that causes large increases in breathing or heart rate? • How many days per week do you do these (moderate/vigorous) activities for at least 10 minutes at a time? • On days when you do (moderate/vigorous) activities for at least 10 minutes at a time, how much total time per day do you spend doing these activities? Answers to these questions show that women in Arizona are more likely to be inactive than men (26.2 percent vs. 18.3 respectively). Physical activity seems to decline with age. Arizonans 45-54 were more likely to be physically active than those over 65 (79.6 vs. 68.5 respectively). Chapter 2 59 1 were much more likely to be physically active than Hispanics (69.2 percent). Whites (81.4 percent) Socioeconomic status was related to physical activity as well. Those who belong to lower income households were more likely to be physically inactive compared to those in higher income households. Nearly 40 percent of adults in households earning less than $15,000 a year reported being physically inactive, compared to only 10.4 percent of those in households earning more than $50,000. There was also a similar trend by education level, where those who were less educated were more likely to be physically inactive compared to those who were more educated. Nearly 40 percent of those who had less than a high school education reported insufficient physical activity compared to 12.3 percent of college graduates (table 4).

Similar to the trend in Arizona adults, more girls (10 percent) than boys (7.5 percent) reported being physically inactive. Physical activity seems to decrease slightly as the children get older. More Hispanics (10.1 percent) than Whites (7.6 percent) or Blacks (5.9 percent) reported physical inactivity. However, there was no distinguishable trend between race/ethnicity and physical inactivity. Nevertheless, Arizona adolescents need to increase their levels of physical activity. This can be accomplished through better health education, more physical education and activity, and environments that encourage physical activity outside of school (table 5).

Being overweight and obese has many detrimental health effects such as CHD, hypertension, type 2 diabetes, stroke, osteoarthritis, cancers (breast and colon) as well as sleep apnea and respiratory problems. In order to determine overweight and obese populations, health professionals use BMI scales, which are calculated using height and weight measurements. Those with a BMI of 25-29.9 are considered overweight and those with a BMI of 30 or more are considered obese (http://www.cdc.gov/nccdphp/dnpa/obesity/index.htm, 2007). Flegal et al. (2005) calculated that obesity contributed to 111,909 excess deaths in the US in 2000, with a majority (82,066 deaths) among people with a BMI of at least 35. Among obese persons in the US, CVD is the leading cause of death. According to the 2006 BRFSS, 36.7 percent of Arizona adults are overweight but not obese, and 22.9 percent are obese (figure 67).

In Arizona, the percentage of those who are overweight or obese is nearly 60 percent, and there are no indications that this trend is beginning to slow. Females, those in younger age groups, and those with more education tend to report healthier weights. More males (45.3 percent) than females (27.7 percent) indicate they are overweight. The likelihood of being overweight increases with age. There was no real difference between genders for those who were obese. However, there was a difference in later age groups among those who were obese. For example, the percentage of adults who are obese between the ages 55-64 and over 65 are 33.1 percent and 15.1 percent, respectively (table 6).

The first is “at risk of becoming overweight,”: which is defined as students who were at or above the 85th percentile but below the 95th percentile for body mass index, by age and sex. The second is “overweight” which is defined as students who were equal to or greater than the 95th percentile for body mass index, by age and sex (http://www. cdc.gov/healthyyouth/yrbs/index.htm, 2007) Among Arizona adolescents, the risk of becoming overweight or being overweight constitutes at least 12 percent of 9th-12th graders. About 14 percent of young Arizonans are at risk of becoming overweight with more of them being males than females. Moreover, 16.5 percent of males are overweight compared to 6.9 percent of females. According to the YRBSS for Arizona 2005, 11th graders have higher percentages of being or becoming overweight, compared to the other grades. In addition, Hispanic (16 percent) adolescents had a higher percentage of being overweight (table 7) compared to White (8.4 percent) and Black (9.7 percent) adolescents.

Smokers are at least twice as likely to die from CHD as nonsmokers; moreover, those who are exposed to other people’s smoke (secondhand smoking) are also at risk (http://www. americanheart.org, 2007). Nearly one third of CVD related deaths are caused by tobacco (Mathers & Loncar, 2006). Additionally 52 percent of those who were diagnosed with at least one circulatory condition continued to smoke (John et al., 2006). Currently18.2 percent of Arizona adults smoke, which is down 20 percent from 2002. However, it is still higher than the HP2010 goal of 12 percent (figure 69).

There are still a large number of individuals who are current smokers. More males (21.7 percent) than females (14.7 percent) reported that they were current smokers. As Arizonans become older the proportion of current smokers decreases, especially for those aged 65 and older. The largest numbers of smokers were between the ages of 45-54. More Blacks than Whites or Hispanics were likely to be smokers. There was no clear distinction between household income and those who were current smokers. However, there was a smaller proportion of current smokers from a household income of $50,000 or more (15.4 percent) compared to those who were from household incomes of less than $15,000 (23 percent) or between $25,000-34,999 (25.4 percent). The results showed a relationship between education and smoking. Those with less than a high school education were much more likely to be smokers, compared to college graduates (23.5 percent vs. 13.2, respectively) (table 8).

Increasing the intake of fruits and vegetables to the recommended ‘5-A-Day’ is beneficial in preventing chronic diseases and improve the quality of an individual’s life. According to the 2005 BRFSS, 74 percent of Arizonans are not eating enough fruits and vegetables.

Several questions pertaining to fruits and vegetables were used in order to calculate fruit vegetable consumption: • How often do you drink fruit juices such as orange, grapefruit, or tomato? • How often do you eat (fruit, green salad, potatoes, carrots)? • Not counting carrots, potatoes, or salad, how many servings of vegetables do you usually eat? According to the 2005 data, more males (80.1 percent) than females (71.8 percent) are getting adequate amounts of fruits and vegetables every day. Consumption of fruits and vegetables increases with age, especially for those over 65 years of age (19.9 percent) compared to those between 18-24 years of age (32.2 percent). However, there was a correlation between education levels and consuming enough fruits and vegetables. Those who had less than a high school education (21 percent) were less likely to be eating ‘5-A-Day’ than those who were college graduates (27.2 percent) (table 10).

Although there are several types of diabetes, the two main types are type 1 (juvenile diabetes), and type 2 (adult-onset) diabetes. Type 1 diabetes is unpreventable and comprises 5-10 percent of all diagnosed cases. The risk factors associated with this type of diabetes may be autoimmune, genetic or environmental. Type 2 diabetes comprises of 90-95 percent of all diagnosed cases and is associated with many risk factors such as age, obesity, family history, gestational diabetes, physical inactivity, and race/ethnicity. In 2002 the costs associated with diabetes, both direct and indirect, were $132 billion (CDC Fact Sheet, 2005). In order to assess the prevalence of diabetes in Arizona, the question asked in the BRFSS relating to diabetes, “Have you ever been told by a doctor that you had diabetes?” was analyzed. The prevalence of diabetes among Arizona adults in 2006 was 8.5 percent, the highest percentage ever recorded in the state, and higher than the national rate. Similar to national trends, more males (9.4 percent) than females (7.7 percent) and more Hispanics (9.2 percent) than Whites (7.8 percent) had diabetes. Nationally, 9 percent of Whites 20 years and older have diabetes; however, the prevalence increases with other racial/ethnic groups. Diabetes is almost twice as common in African Americans than Whites, and 1.7 times more likely in Hispanics than Whites. Estimates of diabetes prevalence among American Indians quite likely are less accurate than other populations, but Chapter 2 70 existing data shows that the prevalence of diabetes in this population is 1.5 to 2.2 times higher than Whites (Rosamond et al., 2007). According to the 2006 BRFSS report, individuals are more likely to report they had diabetes as they age. For example, those who are 45 and older have higher percentages (12.9 to 15.4 percent) of diabetes than those who are less than 44 years old (0.4 to 3.8 percent). Diabetes prevalence also varies by income. Persons who live in households with an income of less than $15,000 were twice as likely to be diabetic compared to those with a household income of over $50,000 (15.2 percent vs. 6.6 percent) (table 12).

CDC reports that heart disease and stroke rates are 2 to 4 times higher in those with diabetes than those without diabetes. Two out of every three persons with diabetes will die from heart disease or stroke. (CDC, 2005). In order to assess what percentage of Arizona adult respondents with CVD, CHD, and stroke also had diabetes, the responses to the appropriate 2006 BRFSS disease related questions were analyzed. A staggering 25 percent of those who said they had a heart attack, angina, and/or stroke also had diabetes. Approximately 22 percent reported having both CHD and diabetes, and about 8 percent reported having been told they had a stroke and diabetes (table 13).

These risk factors, although non-modifiable, are useful in assessing one’s risk for developing CVD, determining the risk thresholds for other modifiable risk factors and interpreting screening and diagnostic tests for CVD. Race Nationally, cardiovascular disease is the leading cause of death and disability. When looking at the diseases of the heart specifically, heart disease is the leading cause of death for all populations, regardless of race or ethnicity and gender. National data (2004) reveal that African Americans suffer the highest age-adjusted mortality rate for heart disease at 306.7 and Whites have the second highest mortality rate at 238.2. This shows that African Americans die from heart disease at a rate that is nearly 30 percent higher than Whites. This pattern is the same with the African American population in Arizona, with an even higher mortality rate from heart disease at 343.3. The Hispanic population has the second highest mortality rate for heart disease with a rate of 266.1. Figure 20, discussed earlier in this document, shows a comparison of mortality rates for heart disease and other leading causes of death in Arizona by race/ethnicity. Figures 44 through 46, discussed on pages 51 – 52, show the 2005 hospitalization rates for heart disease in Arizona. The highest rate of hospitalization from CVD in Arizona was among Whites 139.6 per 10,000 population. The second highest rate of hospitalizations was among African Americans at 114.5 per 10,000 population. When comparing this to the mortality rates discussed in the previous paragraph, African Americans are hospitalized less for CVD, even though they have the highest mortality rate by a large margin. The lowest rate of hospitalizations occurred in the American Indian population at 36.2 per 10,000 population. The hospitalization rate for the American Indian population is artificially low because the state database for hospitalization does not capture events at Indian Health Service facilities. The other component of CVD is stroke, and independent of heart disease, stroke is the third leading cause of death in the United States and accounted for around one out of every 14 deaths in the United States in 2000. Stroke mortality rates in the US for the year 2004 are higher for African Americans than for White (77.0 vs. 54.5). In Arizona, the highest stroke mortality rate is among African Americans, with a mortality rate that is lower than the national average for African Americans. The other population that has high stroke mortality compared to the other ethnic groups is the Asian population, with a rate of 64.6. All other racial/ethnic groups have significantly lower mortality rates compared to African Americans. Shown earlier in this document, Figure 58 shows a comparison of stroke mortality by racial/ethnic group and gender. Chapter 3 74 Figure 46 compares the hospitalization rates for stroke in Arizona among the five largest racial and ethnic groups. Whites in Arizona continue to have the highest rates for hospitalization due to stroke with a rate of 34.1 per 10,000 population. African Americans have the second highest hospitalization rate for stroke with a rate of 24.9 per 10,000 population. American Indians have the lowest hospitalization rates for stroke with a rate of 8 per 10,000 population. Again, the hospitalization rate for the American Indian population is artificially low because the state database for hospitalization does not capture events at Indian Health Service facilities. Age It has been shown throughout this document that age is a major risk factor for cardiovascular disease. Generally, atherosclerotic lesions are the result of a progressive process that develops over years. As a person ages, their aortic system stiffens, thus increasing the blood pressure and risk for a cardiac event. According to the NHLBI, approximately 72 percent of the people who suffer a stroke are age 65 years and older, and the incidence of stroke more than doubles in each successive decade after the age of 55. From 1999-2004, the crude mortality rate for heart disease was highest among those aged 85 and older at 4,574.7 population. The crude mortality rate for stroke was also highest in those aged 85 and older at 1,273, as shown in figure 48. The hospitalization rate for cardiovascular disease in the 65 and older population was 805 per 10,000 in 2005 (see figure 45). Gender Gender is an important non-modifiable risk factor for the development of cardiovascular disease, which is the leading cause of death in both genders, in Arizona and nationwide. The age-adjusted mortality rate in 2005 for heart disease among males was more than 60 percent higher than the rate among females, 237.4 vs.147.3 respectively (see figure 18). The age adjusted mortality rate for stroke was very similar among males and females, at 40.0 and 40.5, respectively (see figure 50). These statistics show that men are much more likely than women to die of heart disease, while women and men die of strokes at about the same rate in Arizona. In Arizona, African American women are more likely to die of heart disease than all other female populations with a mortality rate of 266.2. Within the male population, Hispanic men are most likely to die from heart disease, with a mortality rate of 242.2 (see figure 21). Among males, the death rate from stroke is highest among Hispanics (59.8), while African American women are most likely to die from stroke by a large margin 94.1, which is 250 percent higher than in the White population. Chapter 3 75 CHAPTER 4 Economic Impact of Cardiovascular Disease 76 Since CVD is the leading cause of death and disability in the United States, it is not a surprise that it is a primary component of escalating health care costs as well. The American Heart Association Statistics Committee and Stroke Statistics Subcommittee (Rosamond et al, 2007) estimate that CVD (including stroke) will cost America $431.8 billion dollars in 2007. The two biggest components of these costs are those incurred in a hospital ($133 billion), and lost productivity from early deaths ($112 billion). In accounting for around 40% of all deaths, these expensive diseases pose a huge medical, economic, and social burden on society. There is no source of accurate data on state-level costs for these diseases, but one can examine hospital discharge data for estimates of the economic burden. According to Arizona 2005 data, hospital charges from heart disease totaled nearly $3.8 billion, and charges associated with stroke were another $400 million. This does not include in-patient physician charges, non-hospital direct costs such as outpatient charges, or indirect costs associated with missed work, early deaths, etc. It is difficult to determine direct costs for Arizona, but nationally, the estimated cost of cardiovascular disease in 2006 was $403.1 billion, and includes both direct and indirect costs (http://www. americanheart.org/presenter.jhtml?identifier=4475, 2007) The strain on the health care system due to CVD is not just economic. In 2005 alone, there were over 108,000 hospital visits for diseases of the heart, and another 14,000 for stroke. Since many of the victims of these diseases are over the age of 65 and are insured by Medicare, the tax payers bear a huge portion of the economic burden posed by these diseases.

Although economists and public health researchers have found it difficult to show the cost-effectiveness of primary prevention of CVD (Schwappach et al, 2007), it is not so difficult to understand the economic benefit of CVD prevention. Wang et al. (2002) found that healthcare costs for people with CVD are more than double than for those without the disease. Druss et al (2001) found that persons with ischemic heart disease had higher annual per capita treatment costs than persons with the other four leading chronic conditions (depression, diabetes, hypertension, and asthma). According to Druss, this is because some for the procedures that are necessary are also the most expensive procedures in modern medicine. Additionally, because CVD increases with age, many of the people that are receiving these expensive treatments are Medicare eligible, which makes Medicare the primary payor for these treatments. Chapter 4 77 Stroke is one of the leading causes of disability in the United States. Not only does it pose a huge burden on the health of Americans, but it poses one of the largest economic burdens of any disease. Researchers at the University of Michigan predicted that from 2005 to 2050, the total costs from stroke in the U.S. will exceed over $1.5 trillion among the white population alone (Brown et al, 2006). The lifetime costs of ischemic stroke were more than $90,000 in 1990, nearly 20 years ago, and may have doubled today. These costs, like the burden of many diseases, are not spread evenly among the American population. Hispanics and African Americans, the two largest minority groups in the US, have a higher incidence of stroke. They are also less likely to have health insurance, have a limited access to quality health care, receive less adequate stroke prophylaxis, and have a higher incidence of ischemic stroke than Whites. Since African Americans and Hispanics have strokes at an earlier age than Whites, the lifetime loss of wages is greater. Most stroke prevention methods are cost-effective and many are cost-saving, such as smoking cessation interventions, drug therapies for hypertension, and tighter control of diabetes.

Al, 2007. “ Heart Disease” include CHD, CHF, part of hypertensive disease, cardiac dysrhytmias, rheumatic heart disease, cardiomyopahy, pulmonary heart disease, and other or ill-defined “heart” diseases. Chapter 4 78 CHAPTER 5 Cardiovascular Disease and Special Populations 79 Similar to many other chronic diseases, cardiovascular disease does not impact all populations equally. Disparities exist on many levels whether they are by gender, age, race, ethnicity, income, education, or all of these. Socioeconomic status Research has indicated that socioeconomic status is related to increased prevalence and mortality from CVD. Those in lower income households were more likely to die from CVD. Not surprisingly, access to healthcare varies greatly according to income level; this observation was found even in countries with universal health plans, indicating that insurance is not the only limitation (Kapral et al., 2002). Individuals with a lower socioeconomic status (SES) are more likely to be at risk for developing CVD, and also to be affected by the quality of care after being diagnosed with the disease. The same is true for Arizona. The prevalence of CVD, CHD, and stroke is more common among Arizona adults who are from lower income households than from higher income households. People from lower income households report having higher rates of almost every risk factor related to CVD compared to those from higher income households. At least 25 percent of those who reported having high cholesterol are from households with an income of $35,000 or less (see table 3). Similar patterns are seen in those with physical inactivity, obesity, smoking, and diabetes. Those who had less education also reported higher percentages of physical inactivity, current smoking, and diabetes compared to those who had more education. African American The age-adjusted mortality rate for CVD in the last six years (2000-2005) shows that African Americans have had the highest death rates compared to other race/ethnic groups , at least 1.5 times higher than the groups with the lowest death rates (see figure 19). The lowest age-adjusted rate 329.8 for African Americans during the six-year period was during 2002, in which American Indians had the lowest rate, at 216.2. African American mortality rates are unsteady compared to the other racial/ethnic groups, which may be due to the group comprising a relatively small percentage of the state population (see figure 18). According to the BRFSS, more African Americans reported that they were current smokers than other racial groups (Whites, Hispanics and others) (see table 8). Compared to national rates, mortality rates from 1980-2004 showed that overall mortality is lower in Arizona; however, there are years when rates are very similar to the national rates (see figure 16). In 2005, African Americans in Arizona were most affected by CVD, CHD and stroke mortality (see figures 17, 30, and 47). African American females have higher mortality rates for CVD than their male counterparts (see figures 20, 21, 31, 39 and 49). Additionally, African Americans die from CVD at an earlier age than all other population groups (see figures 13, 32, 40 and 50). The six-year (2000-2005) stroke trend shows that African Americans had the highest rates until 2005, when stroke rates were similar among Asians and African Americans, worse than all other populations (see figure 51). Chapter 5 80 The 50 and older population Increasing age is a risk factor associated with CVD prevalence and mortality. Lifetime risk of developing CVD for those who are free of CVD events at age 50 were 51.7 percent for men, 39.2 percent for women, with median survivals of 30 and 36 years, respectively (Lloyd-Jones et al., 2006). These numbers change according to the number of risk factors a person has at the time. The lifetime risk of developing CHD at 40 is 48.6 percent for men and 31.7 percent for women. The lifetime risk of developing CHF ranged between 20-21.3 percent (Lloyd-Jones et al., 2002). The risk of having a stroke for those stroke-free at 55 was 1 in 5 for women and 1 in 6 for men (Seshadri, 2006). Those with favorable risk factors in middle age will survive and have better qualify of life 25 years later (LloydJones et al., 2007). As risk factors related to CVD can begin decades before the disease is detected, it is important to take preventive measures as early in life as possible. In Arizona, CVD related deaths start to increase somewhere between the ages of 35 and 44, and about 50 percent of leading causes of death by the 55-64 year old age group are due to CVD (see figure 5). The median age at death for CVD is approximately 81 years old, but differs among racial/ethnic groups (see figure 13). The prevalence of CVD is at least 2-9 times higher in those 65 years and older compared to those in younger age groups (see figure 23). This pattern is similar in both CHD mortality and prevalence (see figures 32 and 33). CHF crude mortality rate begins to exceed the Arizona average rate at 65-74 years of age (see figure 36). The median age at death for those who die of stroke differs greatly among the racial/ethnic groups, by at least 10 years, especially among the African Americans and American Indians compared to the Whites (see figure 53). In addition, the prevalence of those who have experienced stroke is three times higher among those 65 years and older compared to those between 55-64 years of age (see figure 54). Youth/Adolescents Diseases of the heart and stroke among Arizona adolescents are the fifth and eighth leading causes of death, respectively (see figure 6). Although a very small proportion of youth/adolescents are affected by CVD, prevention needs to begin as early in life as possible. Risk factors that are attributed to CVD can be modified to lower the risk of developing the disease later in life. According to the YRBSS, 12th graders were less active than 9th graders (see table 5). This could be due to the fact that physical activity is more likely to be part of the curriculum in 9th grade than 12th grade. More students are at risk for being overweight compared to those who are already overweight. Around 12-15 percent of the student respondents are either overweight or already overweight (see table 7). Being overweight is a risk factor associated with diabetes, which in itself is a risk factor for CVD. The percentage of those who consider themselves as current smokers increases with each consecutive Chapter 5 81 grade (see table 9). A small percentage (14-17 percent) of 9th-12th graders eat the recommended five or more fruits and vegetables per day. These figures show that more fruit and vegetable consumption in adolescents needs to be encouraged as this pattern is also prevalent in the Arizona adult population (see table 11). Furthermore, educating Arizona youth at risk factors and healthy behaviors may reduce disparities that exist among several racial/ethnic groups. For example, young women or Hispanic women know or hear less about heart disease than older or other racial/ethnic groups (Mosca). Herein lies an opportunity to educate young Hispanic females about CVD, and the steps they can take now to prevent the disease later in life. Future of CVD in Arizona For the past 20 years, Arizona has been the second fastest growing state in the United States. The Arizona population has grown from over 3.5 million in 1990 to almost 6.5 million in 2007 (figures 72 and 1, as shown earlier in this document).

As the world’s populations get older maintaining a healthy weight, blood pressure and cholesterol will become ever more important in preventing CVD. Unless blood pressure levels are maintained or reduced it is inevitable that stroke prevalence will increases with an aging population (Kuller, 2000). The number of people diagnosed with diabetes is estimated to increase by 165% from 2000 to 2050, of which the greatest increases will be seen among the minority groups and the elderly (Narayan et al., 2003). This larger population of people with diabetes will increase the percentage of people at risk for all cardiovascular diseases. An increase in the disease that is already the leading cause of death will bring with it an even more significant burden on the healthcare workforce, the economy, and communities (Flegal, 2005). Chapter 5 84 VII G l o s s a r y Age Adjusted Rates – the number of events occurring per 100,000 population per year, calculated in accordance with a standard age structure to minimize the effect of age differences when rates are compared between populations over time. Angina – Chest pain caused by ischemia of the heart muscle and is referred to the chest, arm, neck, jaw and/or back. Asthma – a chronic disease of the respiratory system in which the airway occasionally constricts, becomes inflamed, and is lined with excessive amounts of mucus, often in response to one or more triggers. These episodes may be triggered by such things as exposure to an environmental stimulant (or allergen), cold air, warm air, moist air, exercise or exertion, or emotional stress. Behavior Risk Factor Surveillance Survey – A telephone survey that is administered nationally on an annual basis, and asks standardized questions aimed at assessing the prevalence of risk factors for a variety of diseases and threats to health and quality of life and to measure changes in the population’s risk. Blood Pressure – The pressure, measured in millimeters of mercury (mmHg), exerted against the artery walls. Also considered to be the force required by the heart to move blood through the vascular system.  iastolic blood pressure – The measurement of pressure in the arterial system during the resting phase of D the cardiac cycle when the coronary arteries fill and perfusion of the myocardium takes place. Diastole refers to the resting of the heart.  ystolic blood pressure – The measurement of pressure in the arterial system during the contraction of the S heart when blood is forced out of the left ventricle into the arterial system. Body Mass Index – A height to weight ratio field measurement which is correlated to an increased risk of CVDs. BMI is in units of kg/m2 and is derived by taking the bodyweight of an individual in kilograms and dividing it by the height of that individual in meters squared. Absolute values are used to interpret BMI in adults and CDC’s published growth charts for age and gender are used to interpret BMI in children. Cardiovascular Disease – Refers to a broad spectrum of heart and blood vessel diseases, including heart disease, stroke, and peripheral vascular disease. Atherosclerosis is the underlying disease process of all major forms of Cardiovascular Disease. Cerebrovascular Disease – Affecting the blood vessels supplying blood to the brain. Stroke occurs when a blood vessel bringing oxygen and nutrients to the brain bursts or is clogged by a blood clot. Because of this rupture or blockage, part of the brain does not get the flow of blood that it needs and nerve cells in the affected area dies. Small stroke-like events, such as transient ischemic attacks, which resolve in a day or less, are symptoms of cerebrovascular disease. Cholesterol – A steroid alcohol present in animal cells and body fluids, important in physiological processes, and implicated experimentally as a factor in arteriosclerosis. Glossary 85 VII G l o s s a r y ( c o n t i n u e d ) Chronic Obstructive Pulmonary Disease – A group of disorders that are almost always a result of smoking that obstructs bronchial flow. One or more of the following in varying degrees are present in COPD: emphysema, chronic bronchitis, brochospasm, and bronchiolitis. Congestive Heart Failure – Impairment of the pumping function of the heart as the result of heart disease; heart failure often causing physical disability and increased risk for other CVD events. An inability to pump enough blood through the arterial system to supply the tissues and organs. CHF is diagnosed by measuring the percentage of blood in a chamber of the heart that is pumped out during systole. The term “heart failure” should not be confused with cardiac arrest, which is when the heart actually stops beating. Coronary Heart Disease – this refers to a reduction of blood flow due to thickening and hardening of the arteries that supply the heart muscle. Heart cells are dependant on blood flow through these arteries to provide oxygen and to carry away metabolic products. If the supply is reduced, a person can experience angina. Complete cut off of the blood supply results in the death of heart cells, and a heart attack is experienced. Crude Mortality Rate – The number of deaths for a specific condition in a given region, divided by the population of that region. Current smoker – From the BRFSS, all respondents 18 and older who have ever smoked 100 cigarettes in their lifetime and reported smoking every day or some days. Current Tobacco Use – From the YRBSS, all students who have smoked cigarettes or cigars or used chewing tobacco or snuff on ≥1 of the 30 days preceding the survey. Depression – a state of intense sadness, melancholia or despair that has advanced to the point of being disruptive to an individual’s social function and/or activities of daily living. Diabetes Mellitus – A variable disorder of carbohydrate metabolism caused by a combination of hereditary and environmental factors and usually characterized by inadequate secretion or utilizations of insulin, by excessive urine production, by excessive amounts of sugar in the blood and urine and by thirst, hunger, and loss of weight.  ype 1 Diabetes Mellitus – Type 1 diabetes is a chronic, lifelong disease. It can occur at any age, but is T usually diagnosed in children and young adults. In type 1 diabetes, the body’s immune system has attacked certain cells in the pancreas and destroyed them. Once they are destroyed, the pancreas produces little or no insulin, so glucose stays in the blood.  ype 2 Diabetes Mellitus – Type 2 diabetes occurs in 2 ways, 1) the body does not produce enough insulin, T or 2) the cells ignore the insulin. Type 2 diabetes is the most common form of diabetes and usually appears in adults, often in middle age.  estational Diabetes – Gestational diabetes results from when the body is not able to make and use all the G insulin it needs for pregnancy. Without enough insulin, glucose cannot leave the blood and be changed to energy. Glucose builds up in the blood to high levels. Direct Costs – Costs that are clearly and directly associated with heart disease and stroke treatment. Glossary 86 VII G l o s s a r y ( c o n t i n u e d ) Disparities – refers to the gaps in the quality of health and health care across racial, ethnic, and socioeconomic groups. Fruits and Vegetables: 5-A-Day – from the BRFSS, all respondents 18 and older who report they are consuming five or more servings of fruits and vegetables per day. Heart Disease – any affliction that impairs the structure or function of the heart. Healthy People 2010 – Healthy People 2010, a document created by the US Department of Health and Human Services, with targets to move the US population towards greater health. High Blood Pressure – Blood pressure is the force of the blood pushing against the walls of arteries. Blood pressure is given as two numbers that measure systolic pressure (the first number, which measures the pressure while the heart is contraction) and diastolic pressure (the second number, which measures the pressure when the heart is resting between beats). High Cholesterol – Cholesterol is the waxy substance that circulates in the bloodstream. When the level of cholesterol in the blood is too high, some of the cholesterol is deposited in the walls of the blood vessels. Over time these deposits can build up until they narrow the blood vessels, causing atherosclerosis, which reduces the blood flow. The higher the blood cholesterol level, the greater the risk of getting heart disease. Blood cholesterol levels of less than 200mg/dL are considered desirable. Levels of 240 mg/dL or above are considered high and require further testing and possible intervention. Levels of 200-239 mg/dL are considered borderline. Lower blood cholesterol reduces the risk of heart disease. Hospital Discharges – The number of inpatients discharged from short-stay hospitals where some type of disease was the first listed diagnosis. Discharges include people both living and dead. Indirect Costs – costs that are not directly related to the actual treatment of heart disease or stroke. Medicare – the health insurance program administered by the US government, covering people who are either 65 and older, or who meet other special criteria. Modifiable Risk Factors – attributes or characteristics of a person’s lifestyle, which predisposes them to develop coronary heart disease. Mortality – rate of death expressed as the number of deaths occurring in a population of a given size within a specified time interval. Non-modifiable Risk Factors – Risk factors that are not amenable to modification by an individual such as increased age, family history, gender and ethnicity. Obesity – Often defined in terms of body mass index (BMI), which is calculated as bodyweight in kilograms divided by height in meters squared: A BMI of ≥ 30kg/m2 is considered “obese” Osteoarthritis – a type of arthritis that is caused by the breakdown and eventual loss of cartilage of one or more joints. Glossary 87 VII G l o s s a r y ( c o n t i n u e d ) Overweight – Often defined in terms of body mass index (BMI) which is calculated as bodyweight in kilograms divided by height in meters squared: a BMI of 25-29.9 kg/m2 is considered overweight. In children, the CDC defines overweight as BMI greater than the 95th percentile value for the same age and gender group. Physical Activity – bodily movement that is produced by the contraction of skeletal muscle and that substantially increases energy expenditure.  hysical Inactivity – From the BRFSS, all respondents 18 and older who report no leisure-time physical P activity during the past month.  oderate Physical Activity – Activities that use large muscle groups and are at least equivalent to brisk M walking. In addition to walking, activities may include swimming, cycling, dancing, gardening, and yard work, and various domestic and occupation activities.  igorous Physical Activity – Rhythmic, repetitive physical activities that use large muscles at 70 percent or V more of maximum heart rate for age. Plaque – the characteristic manifestation of atherosclerosis located in the arterial wall and extending into the lumen or channel of the artery; plaque can disturb or restrict blood flow and is prone to fissure or rupture, thus precipitation formation of a blood clot that can cause an acute coronary event. Premature Death – death occurring in the ages of 35-74 Prevalence – the frequency of a particular condition within a defined population at a designated time. Socio-economic Status – a measure of an individual’s place within a social group based on various factors, including income and education. Stroke – Sudden interruption of blood supply to the brain caused by an obstruction or the rupture of a blood vessel. Youth Risk Behavior Surveillance System – a survey designed to determine the prevalence of health risk behaviors in adolescents. Glossary 88 VIII D a t a S o u r c e s & L i m i t a t i o n s CDC Wide-ranging OnLine Data for Epidemiologic Research (WONDER): Compressed Mortality File• WONDER is an online resource available to public health professionals and the public. • Data is available from 1979-2004 and can be broken down according to: number of deaths, crude or ageadjusted death rates, gender, age group, race (white, black and other), year of death and underlying cause of death. • Mortality data based on records for all deaths that occur in the 50 states and the District of Columbia. • Foreign residents who have died in the United States are excluded. US residents who die abroad are also excluded. • Underlying cause of death, determined by the World Health Organization (WHO) International Classification of Disease (ICD)-9 and -10 coding, is determined by the physician when entering it onto the death certificate. [Note: ICD-9 (1979-98) or ICD-10 (99-current year)] • Race category for American Indian or Alaskan Native race category and the Asian or Pacific Islander is classified as ‘Other’. Information from: http://wonder.cdc.gov Arizona Department of Health Services’ (ADHS) Bureau of Vital Statistics• Births, deaths, and fetal deaths from original documents filed with the ADHS and from transcripts of original certificates affecting Arizona residents in any other states. • Death records/certificates of Arizonans who have died outside the US are not included. • Cost Reporting and Discharge Data Review collect information about both hospital inpatient discharges and emergency room visits. • The Bureau of Public Health Statistics requires short-stay nonfederal hospitals to submit uniform reports to ADHS every six months. • A limitation to this approach is that it excludes patient information from federal, territorial, or other small hospitals/hospices (e.g. Indian Health Services). • Population Denominators are projections from Arizona Department of Economic Security (DES) http://www. workforce.az.gov/. Information from: http://www.azdhs.gov/plan/index.htm CDC Behavioral Risk Factor Surveillance System (BRFSS)• BRFSS is on an on-going data collection system gathering information on adult health-related behaviors of non-institutionalized residents 18 years of age and older. A standardized questionnaire (~75 questions) is used. Questions determined by the state BRFSS coordinator and CDC. Data Sources & Limitations 89 VIII D a t a S o u r c e s & L i m i t a t i o n s ( c o n t i n u e d ) • Only one adult per household is interviewed. Participants are not compensated. • Random sampling telephone survey, using disproportionate stratified sampling, random digit dialing, and a Computer Assisted Telephone Interviewing (CATI) system. • Sample size of 4,700 over a 12 month period surveyed (sample size 95 percent confidence interval of ±3 percent). Potential to represent 96.3 percent of all households that have telephones according to the DES for the year 2000 in Arizona. • Monthly data files sent to the Arizona BRFS program and reports are prepared. • Data is weighted based on Arizona population demographics. • Takes into account number of adults and telephone lines in the household, cluster size, stratum size and age/ race/sex distribution of the general population. • References to a few articles related to the reliability and validity of the BRFSS are listed below: 1) Nelson DE, Holtzman D, Bolen J, Stanwyck CA, Mack RA.

Information from: http://www.cdc.gov/brfss and http://www.azdhs.gov/plan/brfs/ CDC Youth Risk Behavior Surveillance System (YRBSS) – • Every two years students (grades 9-12) are selected from a representative sample of high schools in a state to take self-reported paper and pencil questionnaires. • These questionnaires are administered to determine the prevalence of risk factors and behaviors: unintentional injuries and violence, tobacco use, alcohol and other drug use, sexual behaviors, unhealthy dietary behaviors and physical inactivity. • In existence since 1991, last reported year was in 2005. • A limitation is that it is a self-reported questionnaire so under or over-reporting of behaviors cannot be determined. Data Sources & Limitations 90 VIII D a t a S o u r c e s & L i m i t a t i o n s ( c o n t i n u e d ) • Data represents only those who attend a high school. (About 6% of those aged 16-17 who are not enrolled in a high school are not taken into account.) In addition, not all 50 states participate in the survey which would affect any nationwide estimates. • Survey takes 10 minutes for the facilitator to distribute and to read the directions. It takes 35 minutes for the students to take. • In the YRBSS, only surveys with a scientifically drawn sample, appropriate documentation, and an overall response rate of at least 60% are weighted. (Arizona is weighted.) • YRBS data are weighted to adjust for school and student nonresponse and to make the data representative of the population of students from which the sample was drawn. Generally, these adjustments are made by applying a weight based on student sex, grade, and race/ethnicity.
