The Living Well by Faith Health and wellness program for African Americans: an exemplar of community-based participatory research

Abstract

Background: Using community-based participatory research (CBPR) as a guiding framework, a faith-based diet, nutrition and physical activity intervention for African Americans was implemented and evaluated as a small-scale randomized trial.

Methods: Five churches were recruited (intervention=3, control=2), resulting in an enrolled sample of 106 adults (intervention=74, control=32). The control group received a minimal intervention consisting of one educational workshop. The Living Well By Faith intervention group received a more intensive 8-week program. Classes were held twice a week and included educational workshops and exercise sessions. Both interventions were delivered at participating churches. Assessments for program evaluation occurred at baseline and 2-month follow-up. These included weight, blood pressure, percent body fat, and physical fitness using the step test.

Results: The sample was predominantly African American, female and well educated. At baseline, no significant differences between intervention and control groups were found for any of the primary endpoints. At 2-months follow up, the intervention group, compared to the control group, showed significant decreases in weight (P<.02), BMI (P<.05), and % body fat (P<.03), with a significant increase in physical fitness (P<.02). Systolic blood pressure also showed group differences in the predicted direction (P=.10).

Conclusion: This study provides an exemplar of CBPR. The results obtained are sufficiently promising to support more research involving similar interventions of longer duration and with longer-term follow-up for evaluation.
