Abstract

Background: Hispanics/Latinos of Dominican background living in United States (US) have the highest hypertension prevalence compared with other Hispanic/Latino persons.

Objective: To understand cardiovascular health among Dominicans, we evaluated hypertension prevalence and risk factors among Dominicans from the US and Dominican Republic (DR) using data from Hispanic Community Health Study/ Study of Latinos [HCHS/SOL] and the Prevalencia de Hipertension Arterial y Factores de Riesgo Cardiovasculares en la República Dominicana al 2017 (ENPREFAR-HAS 17) study.

Methods: Hypertension was defined as blood pressure ≥140/90 mmHg, self-reported hypertension, or antihypertensive use. Exposures included sociodemographic/socioeconomic, clinical, and lifestyle/behavioral characteristics. Weighted generalized linear models were used to estimate associations between study characteristics and hypertension prevalence (PR = prevalence ratio), age-and-sex adjusted. HCHS/SOL (n = 1,473, US Dominicans; mean age 41 years, 60.4% female) was analyzed with survey procedures, while ENPREFAR-HAS 17 (n = 2,015 DR Dominicans; mean age 40 years, 50.3% female) was analyzed with statistical analyses for simple random sampling.

Results: Hypertension prevalence was 30.5% and 26.9% for DR and US Dominicans, respectively. Hypertension control was low in both cohorts (36.0% DR, 35.0% US). Alcohol use among DR Dominicans was inversely associated with hypertension prevalence (PRDR = 0.8) with no association among US Dominicans. In both settings, diabetes (PRDR = 1.4; PRUS = 1.4) and obesity (PRDR = 1.8; PRUS = 2.0) were associated with greater hypertension prevalence in Hispanics/Latinos of Dominican background. Physical activity was lower among US Dominicans (PR = 0.80) but higher among DR Dominicans (PR = 1.16); all p < 0.05.

Conclusions: Variations in social, lifestyle/behavioral, and clinical characteristics associated with hypertension among Dominicans in the US and DR were identified, suggesting that social context and cultural factors matter among immigrant populations.
