Abstract 17062: Disparities in Cardiovascular Mortality Among Disaggregated Asian Groups: Results From the 1999-2018 National Health Interview Survey

Abstract

Background: Asian people generally have lower cardiovascular (CVD) morbidity and mortality relative to other race and ethnic groups. However, few studies have examined differences in CVD mortality among disaggregated Asian groups. Additionally, mortality data often lack comprehensive information on social and socioeconomic factors which could contribute to differences in mortality by race. Methods: Using the 1999-2018 National Health Interview Survey linked to the National Death Index, we examined cardiovascular (CVD) mortality among Asian Indian (N=4,660), Chinese (N=4,823), Filipino (N=4,835), and Other Asian (e.g., Korean, Japanese, Vietnamese, N=8,472) and Non-Hispanic White adults (N=312,850). We examined 5 nested multivariable Poisson regression models comparing CVD mortality of disaggregated Asian groups accounting for demographic, social, and socioeconomic factors, and body mass index (BMI). Results: There were vast differences in CVD mortality by 2018 follow up and participant characteristics by race and ethnicity. CVD mortality was lower among each disaggregated Asian ethnic group relative to Non-Hispanic White people (Table). Asian Indians were lowest (IRR = 0.19, 95% CI = 0.11, 0.30), followed by Chinese (IRR = 0.33, 95% CI = 0.24, 0.46), then Filipino (IRR = 0.46, 95% CI = 0.36, 0.60) and Other Asian (IRR = 0.54, 95% CI = 0.43, 0.69). This advantage remained when adjusting for age and sex, social factors, socioeconomic status, and BMI for all Asian groups except for Other Asians. Conclusions: Asian people have a CVD mortality advantage compared to Non-Hispanic White people. Demographic, social, and socioeconomic factors, and BMI accounted for some, but not all of the differences in CVD mortality among Asian groups compared to Non-Hispanic White people. Future epidemiological study should focus on the social and environmental factors that promote health among Asian groups.
