Asian American Heart Study
Despite the increasing ethnic diversity of the U.S. population, limited information is available about cardiovascular disease among Asians, one of the nation's fastest growing minority groups. Asian racial/ethnic subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese) are often aggregated in clinical and population-based studies because of small numbers. Therefore the prevalence of stroke and coronary heart disease, as well as cardiovascular disease risk factors, is unknown in specific Asian racial/ethnic subgroups. Our goal was to identify differences in cardiovascular disease risk among Asian Americans, so that we can improve the health care of Asian Americans.
We proposes a construction of a record-linked, electronic cohort by combining existing clinical databases in a large (20,000), multiethnic sample of contemporary Asian populations in the San Francisco Bay Area, all of whom have access to medical care. We then defined Asian subgroups through self-reported race/ethnicity, and will include a Non-Hispanic White (NHW) comparison population.
With NHWs as the comparison group, our specific aims were:
(1) to determine differences in the prevalence of cardiovascular disease (stroke and coronary heart disease) across Asian racial/ethnic subgroups, and between Asian racial/ethnic subgroups and NHWs;
(2) to determine whether the associations between body mass index (BMI) and cardiovascular disease risk factors vary across Asian racial/ethnic subgroups and between Asian racial/ethnic subgroups and NHWs.
