RESUMO
BACKGROUND: Latinos and Asians in the United States are disproportionately burdened by hypertension, a leading risk factor for cardiovascular disease. Few studies have used multicomponent measures of acculturation to compare cardiovascular risk factors across immigrant-origin groups. Additionally, little is known about how acculturation and gender shape hypertension risk among immigrants. METHODS: We created an acculturation score composed of language use, nativity, and years in the United States and fit separate race/ethnicity log-binomial models examining associations with hypertension prevalence (≥130/80 mm Hg) among Latino (n = 4,267) and Asian (n = 2,142) National Health and Nutrition Examination Survey 2011-2016 participants aged 18+. Joint effect models tested the concept of "intersectionality" between acculturation and gender. RESULTS: Adjusting for age, gender, and socioeconomic position, Latinos and Asians with high acculturation were 25% and 27% more likely to have hypertension, respectively, compared with low acculturation groups. Latino and Asian American men with high levels of acculturation were 74-79% more likely to have hypertension compared with women with low acculturation (adjusted prevalence ratios (aPR) for Latinos = 1.74, 95% confidence interval (CI): 1.49-2.03; aPR for Asians = 1.79, 95% CI: 1.42-2.25). The gradient of increasing hypertension with increasing acculturation was most apparent among Latino men (adjusted risk differences (aRD) = 12.0%, P < 0.001) and Asian women (aRD = 14.0%, P = 0.003) and nonsignificant among Latino women and Asian men when comparing high vs. low acculturation categories. CONCLUSIONS: Our results correspond with prior literature demonstrating increased morbidity among immigrants with increasing acculturation but also suggest differing patterns by race/ethnicity and gender. Future research should explore how migration processes differentially influence hypertension among men and women.
