ABSTRACT
Importance Higher social vulnerability is associated with premature cardiovascular disease (CVD) and mortality but is understudied in low-income countries that have both the highest magnitude of social vulnerability and a growing CVD epidemic. Objective:
To evaluate the association between social vulnerability and hypertension, CVD, and CVD subtypes in Haiti as a model for similar low-income countries. Design, Setting, andParticipants:
This population-based cohort study used enrollment data from adults participating in the Haiti Cardiovascular Disease Cohort Study. Recruitment occurred via multistage random sampling throughout slum and urban neighborhoods in Port-au-Prince, Haiti, from March 2019 to August 2021. Data were analyzed from May 2022 to December 2023. Exposures A modified Haitian Social Vulnerability Index (SVI-H) was created following the US Centers for Disease Control and Prevention Social Vulnerability Index method. Twelve variables across the domains of socioeconomic status, household characteristics, and social and community context were included. The SVI-H was calculated for each study neighborhood block and then stratified into SVI-H quartiles (quartile 1 was the least vulnerable; quartile 4, the most vulnerable). Main Outcomes andMeasures:
Prevalent hypertension and total CVD, defined as heart failure (HF), stroke, transient ischemic attack (TIA), angina, or myocardial infarction (MI). Age-adjusted Poisson regression analysis yielded prevalence ratios (PRs) comparing the prevalence of hypertension, total CVD, and CVD subtypes across SVI-H quartiles.Results:
Among 2925 adults (1704 [58.3%] female; mean [SD] age, 41.9 [15.9] years), the prevalence of hypertension was 32.8% (95% CI, 31.1%-34.5%) and the prevalence of CVD was 14.7% (95% CI, 13.5%-16.0%). Hypertension prevalence ranged from 26.2% (95% CI, 23.1%-29.3%) to 38.4% (95% CI, 34.8%-42.0%) between quartiles 1 and 4, while CVD prevalence ranged from 11.1% (95% CI, 8.8%-13.3%) to 19.7% (95% CI, 16.8%-22.6%). SVI-H quartile 4 vs 1 was associated with a greater prevalence of hypertension (PR, 1.17; 95% CI, 1.02-1.34) and CVD (PR, 1.48; 95% CI, 1.16-1.89). Among CVD subtypes, SVI-H was significantly associated with HF (PR, 1.64; 95% CI, 1.23-2.18) but not with combined stroke and TIA or combined angina and MI. Conclusions and Relevance In urban Haiti, individuals living in neighborhoods with the highest social vulnerability had greater prevalence of hypertension and HF. Understanding CVD disparities in low-income countries is essential for targeting prevention and treatment interventions toward populations at highest risk globally.
