abstract
BACKGROUND: Elevated blood pressure (BP) is the leading cause of death globally, with the greatest burden in low-and-middle income countries. Longitudinal BP data are limited in settings of extreme poverty. We identified longitudinal BP trajectories and associated risk factors in urban Haiti. METHODS: We analyzed data from 2073 adults (≥18 years) with ≥3 facility-based BP measurements between March 2019 and April 2025 in the population-based Haiti Cardiovascular Disease Cohort. Demographic, behavioral, and clinical data were collected annually. Participants received routine clinical care based on Ministry of Health guidelines. Latent class growth mixture modeling identified systolic BP trajectory groups. Enrollment characteristics associated with BP trajectory group membership were analyzed using multivariable generalized-logit models. RESULTS: At study enrollment, median age was 43 years (interquartile range, 30-56); 60% were female,100% identified as Black Haitian, and 69% lived on
