Better Me Within Randomized Trial: Faith-Based Diabetes Prevention Program for Weight Loss in African American Women

Previous DPP translations in African American women have been suboptimal. This trial evaluated a community-based participatory research developed faith-based diabetes prevention program (DPP) to improve weight loss in African American women.

This cluster randomized trial allocated churches to faith-based (FDPP) or standard (SDPP) DPP interventions. Setting. African American churches. Subjects. Eleven churches with 221 African American women (aged 48.8 ± 11.2 years, BMI = 36.7 ± 8.4) received the FDPP (n = 6) or SDPP (n = 5) intervention.

FDPP incorporated 5 faith-based components, including pastor involvement, into the standard DPP curriculum. The SDPP used the standard DPP curriculum. Lay health leaders facilitated interventions at church sites.

Weight and biometrics were collected by blinded staff at baseline, 4- and 10-months.

A multilevel hierarchical regression model compared the FDPP and SDPP groups on outcomes.

FDPP and SDPP churches significantly lost weight at 10-months (overall -2.6%, p < .01). Women in FDPP churches who attended at least 15 sessions lost an additional 6.1 pounds at 4-months compared to SDPP corresponding to a 5.8% reduction at 10-months (p < .05). Both groups had significant improvements in health behaviors and biometrics.

Faith-based and standard DPP interventions led by lay health leaders successfully improved weight, health behaviors, and chronic disease risk. However, the faith-based DPP when fully implemented met the CDC's recommendation for weight loss for diabetes prevention in African American women.
