Design of MOSAAIC (Multi-Ethnic Observational Study in American Asian and Pacific Islander Communities)

Résumé fourni par la source

BACKGROUND: Asian American (AsA) and Native Hawaiian and Pacific Islander (NHPI) populations are underrepresented in U.S. health studies. OBJECTIVES: The MOSAAIC (Multi-ethnic Observational Study in American Asian and Pacific Islander Communities) is a cohort study designed to improve understanding of disparities in cardiovascular disease and other health conditions affecting AsA and NHPI groups. METHODS: Through broad eligibility criteria and outreach tailored to each study community, MOSAAIC will include 11,500 adults aged 18+ years living in 5 field center regions: New York, Philadelphia, Chicago, San Francisco Bay Area, and Honolulu. The protocol specifies sample-size targets to allow valid comparisons among persons having personal or family origins in 4 geographically defined regions, including East Asia (the largest groups being Chinese and Korean), South Asia (Indian), Southeast Asia (Vietnamese and Filipino) and Oceania (NHPI). Measurements to be obtained at an in-person examination include clinical laboratory tests, medical history, medication use, spirometry, cognitive and physical function, anthropometry, and electrocardiogram. Surveys in multiple languages to assess medical, behavioral, lifestyle, social and environmental influences on health were developed by a multistep process to ensure equivalency between translations and cultural appropriateness. Biospecimens are stored for future studies. Long-term follow-up will be conducted to ascertain and adjudicate major health events including myocardial infarction, stroke, heart failure, and mortality. CONCLUSIONS: The National Institutes of Health established MOSAAIC as a resource for wide-ranging epidemiologic investigation of factors related to cardiometabolic, pulmonary, or mental health in persons of diverse AsA and NHPI background.
