The Impact of Promotoras on Social Support and Glycemic Control Among Members of a Farmworker Community on the US-Mexico Border

PURPOSE: The purpose of this study is to describe the effect of a promotora-driven intervention to build social support as a means to affect self-management behaviors and clinical outcomes in a farmworker community on the US-Mexico border. METHODS: Promotoras implemented a community-based intervention that included support groups, home/hospital visits, telephone support, and advocacy to people with diabetes. A 12-month pre/post study design was used to investigate the relationship between promotora contact, perceived support, and clinical outcomes. Clinical data were gathered from 70 participants during routine physician visits. A pre/post questionnaire was used to measure perceived support and self-management practices. RESULTS: Glycosylated hemoglobin (HbA1c) levels decreased 1% among high-risk participants. Improved HbA1c level was associated with promotora advocacy and participation in promotora-led support groups. Participants reported increased support from family and friends and more comfort speaking about diabetes (la enfermedad) with family and friends. CONCLUSIONS: These findings document improvement in both clinical and social health indicators for Mexican Americans in a farmworker community when a promotora model is used to provide and facilitate culturally relevant support for diabetes self-management practices.
