Abstract P091: Atrial Fibrillation Prevalence and Clinical Correlates Among Diverse Hispanic/Latinos: The Hispanic Community Health Study / Study of Latinos (HCHS-SOL)
Introduction: Hispanics are the largest minority ethnic group in the US. There is limited data on the epidemiology of AF on Hispanic/Latino populations. Previous studies examined Hispanics/Latinos as an aggregate group or only Mexicans. Methods and Results: Total of 16,415 adult men and women HCHS-SOL participants were included in the analyses (60% women, 59% age > 45 years) representative of major US Hispanic background groups: Cuban (CU), Dominican (DR), Mexican (MX), Puerto Rican (PR), Central American (CA), and South American (SA). AF was defined by 12-lead ECG and/or self-report of a physician diagnosis. Ethnic-specific AF prevalence rates were determined. Weighted sequential logistic regression models were adjusted for demographic factors (age, sex, education) and clinical variables (diabetes, hypertension, body mass index, tobacco use, and eGFR). Overall AF prevalence was 0.97% (n=162) with highest prevalence among DRs and PRs (1.8% and 2.5% respectively) and the lowest among MXs (0.30%). Diabetes, hypertension and acculturation (language preference) (all p<0.01) were significantly associated with higher AF prevalence. Age-sex adjusted analysis by Hispanic background with MX as the reference showed DR, CU, and PR at three-fold to six-fold higher risk than their MX counterparts. (Table) In full multivariate models, the effect size for PR and DR groups was somewhat attenuated but for CUs and CAs the association became marginally non-significant. Conclusions: In a diverse population-based cohort of US Hispanics/Latinos AF prevalence overall was less than 1%. Increased acculturation was related to higher AF prevalence. AF prevalence varies significantly across Hispanic/Latino groups with DR and PR particularly at risk independent of clinical or demographic factors.
