What this trial studies

This observational study aims to identify trends and associations in psychosocial, dietary, and cardiometabolic risk factors among adults in Puerto Rico. It will establish a longitudinal cohort of 2,000 adults aged 30-75, recruited through community sampling, and assessed at various partner clinics across the island. The study will collect extensive data on psychosocial factors, dietary habits, cardiovascular disease markers, and medical records, with follow-ups occurring every two years. The research will also explore variations based on urban-rural residency and the impact of Hurricane Maria.

Why it matters

Potential benefit: If successful, this study could inform public health strategies to reduce cardiovascular-related health disparities in Puerto Rico.

How similar studies have gone: Other studies focusing on psychosocial and environmental factors in minority populations have shown promise, indicating that this approach could yield valuable insights.
