snoring as a risk factor for this syndrome has been reported elsewhere (Troxel et al., 2010) CM Baldwin 2013© Not to be reproduced without permission Implications • Consistent with large cross-sectional studies, Mexican Americans and Mexicans with sleep symptoms are at greater risk for DM, CVD, PD or depression • Future studies should examine the influence of ‘acculturation’ on sleep health of Mexican Americans and migrants to other countries • Findings underscore the need for ‘immigration health’ training for providers and culturally relevant sleep education, interventions and policy in nursing research and practice and research bi-nationally to – – – – Reduce and prevent comorbidities Promote healthy lifestyles (sleep, diet, activity) Reduce health care costs Improve quality of life among respective populations in the U.S. and Mexico CM Baldwin 2013© Not to be reproduced without permission Outcome for Promotoras: Su Sueño/Su Vida Carol M.
