Community-Based Evaluation of Hypertension Awareness and Knowledge Among Underserved Bateyes in the Dominican Republic.

BACKGROUND

Globally, hypertension rates are rising, particularly in low-income nations where access to healthcare and education remains limited. In the Dominican Republic, marginalized Haitian migrant communities, known as Bateyes, face disproportionate burdens. However, limited information exists on their understanding of hypertension and related health risks. This program-based evaluation aimed to explore community knowledge as part of ongoing outreach efforts.

METHODS

We conducted a descriptive analysis of responses from 379 adults across three Bateyes in the Puerto Plata region. Participants completed a 15-item hypertension knowledge questionnaire during a routine mobile medical screening program (December 2022-January 2023) coordinated by the Kerolle Initiative. Hierarchical clustering was used to identify knowledge patterns and explore associations with community differences and systolic blood pressure (SBP) levels.

RESULTS

Average BP values were 133/84 mmHg for males and 125/84 mmHg for females, with 27% of respondents meeting the clinical threshold for hypertension. Knowledge levels varied with 44% of participants having insufficient knowledge, and only one participant demonstrating adequate knowledge. Knowledge was associated with education level and household income. Poor awareness of basic concepts emerged as a key driver of variation across Bateyes. Cluster analysis revealed three knowledge patterns: (1) awareness shaped by lived experience of hypertension; (2) gaps due to common misconceptions; and (3) protective behaviors likely influenced by broader public messaging.

CONCLUSION

Findings from our educational outreach program evaluation suggest variable hypertension awareness across Batey communities. These observations highlight key areas for tailoring future community-centered health education efforts to the local needs of Bateyes.
