Abstract

BACKGROUND: Differences in prevalence of risk factors such as hypertension may explain heterogeneity in cardiovascular risk across Asian American populations.

METHODS: We used National Health Interview Survey (NHIS) data from 2006 to 2018 among White, Chinese, Asian Indian, Filipino, and 'other Asians' (Japanese, Korean, and Vietnamese). Unadjusted and adjusted odds ratios (aOR) with 95% confidence intervals were reported using logistic regression models for the association between race and self-reported premature hypertension (ageold). Models were adjusted for sex, education, body mass index, smoking status, diabetes, and coronary heart disease.

RESULTS: We studied 99,864 participants with history of hypertension (mean age, 59.3 ± 0.1; 50% women, 90% US born). Asian Indians had higher prevalence of premature hypertension (37%) compared with Filipinos (27%), 'other Asians' (26%), Whites (25%), and Chinese (21%). Compared with Whites, Chinese individuals had lower odds of premature hypertension (aOR = 0.79, 0.63-0.98), but Asian Indians had higher odds (aOR = 1.85, 1.48-2.31). Compared with Chinese, odds of premature hypertension was higher for Asian Indians (aOR = 2.39, 1.74-3.27), Filipinos (aOR = 1.53, 1.16-2.04), and 'other Asians' (OR = 1.32, 1.03-1.70; aOR = 1.59, 1.20-2.10). Overall prevalence of hypertension was lower among Asian Indians (aOR = 0.52, 0.46-0.58) and 'other Asians' (aOR = 0.74, 0.68-0.79) compared with Whites.

CONCLUSIONS: There is heterogeneity in the risk of hypertension across Asian Americans by age. Asian Indians and 'other Asians' had higher prevalence of premature hypertension and lower prevalence of overall hypertension, which may call for earlier screening for risk factors among these populations.
