Abstract P353: Association of United States Nativity With Cardiovascular Health Among Race and Ethnic Groups

Abstract

Introduction: Lived experiences based on self-identified race and ethnicity or place of birth are important determinants of cardiovascular health (CVH). However, the association of US nativity with CVH among different race and ethnic subgroups is not well studied. Hypothesis: We hypothesized that CVH will be higher among adults born outside the US compared with adults born in the US. Methods: We included participants aged ≥18 years from the National Health Interview Survey from 2011 through 2018. CVH was calculated based on 5 available metrics: hypertension, diabetes, cholesterol, smoking, and body mass index calculated from self-reported height and weight. Scores ranged from 0 (low CVH) to 10 (high CVH). Nativity was classified as born in or outside the US. Survey-weighted linear regression models examined the association between CVH and US nativity, adjusting for age and sex and stratified by race and ethnic subgroups. Results: Of 117,894 participants (representing 120,295,032 US adults), 51% were female and the mean (SE) age was 45 (0.1) years. Overall, among all combined race and ethnic subgroups, participants born outside the US had significantly higher CVH compared with participants born in the US (beta +0.42; 95% CI: +0.38, +0.46). Hispanic adults (beta +40; 95% CI: +0.32, +0.49), Non-Hispanic Black adults (beta +0.89; 95% CI: +0.77, +1.01), Non-Hispanic Asian adults (beta +0.39; 95% CI: +0.24, +0.54), and Non-Hispanic White adults (beta +0.36; 95% CI: +0.28, +0.45) all had significantly higher CVH compared with adults who were born in the US. The age-and sex-adjusted CVH scores by U.S. nativity for overall race and ethnic groups, Hispanic American subgroups, and Asian American subgroups are shown in the Figure. Conclusion: Overall CVH is significantly higher among people born outside the US compared with those born in the US. Among race and ethnic subgroups, people born outside the US had higher CVH compared with those born within the US, except for Asian Indian adults. Figure.
