Improving Weight Loss Outcomes of Black Women Using a Culturally-Relevant Stress-Management Enhanced Behavioral Weight Loss Intervention
The purpose of this study is to test the effects on weight of an evidence-based behavioral weight loss program enhanced with culturally targeted stress management strategies compared to the evidence-based weight loss program alone among adult black females with obesity and elevated stress levels. Participants will be randomized to receive either a behavioral weight loss intervention with a focus on stress management or the weight loss intervention alone for 26 sessions.
Conduct a randomized, controlled trial to determine the effects on body weight of a culturally-targeted, stress-management enhanced BWL intervention (BWL-Stress) compared to a standard BWL intervention alone (BWL-Alone) among adult black females with obesity and elevated stress Evaluate the effects of the stress-management enhanced BWL intervention on psychological stress as measured by a validated survey instrument and a stress biomarker. Using a multiple mediation model, determine whether the relationship between the stress-management enhanced BWL intervention and weight change is mediated by perceived stress, energy intake, and physical activity.
