ABSTRACT
BACKGROUND:
Obesity is a persistent public health concern and a risk factor for many chronic diseases including at least 13 different cancers. Adult Black females have the highest prevalence of obesity (57%) compared to other racial/gender groups in the U.S. Although behavioral weight loss (BWL) interventions have demonstrated effectiveness, Black females tend to lose less weight than White counterparts. The higher prevalence of chronic psychological stress reported by Black females may contribute to their disproportionate prevalence of obesity and observed suboptimal weight loss. This study will examine the effectiveness of a 12-month culturally-targeted, stress management-enhanced BWL intervention on weight loss and stress reduction among Black females in a fully-powered randomized, controlled trial.METHODS:
Adult Black females with obesity (n = 340) will be randomized to either a culturally targeted stress management-enhanced BWL intervention (BWL-Stress) or the same BWL intervention alone (BWL-alone). The primary outcome is weight change at month 6. Secondary outcomes will include changes in stress measures (e.g., perceived stress, cortisol), energy intake, and physical activity at month 6. We will also assess process measures (e.g., treatment adherence, treatment burden). Each outcome will also be evaluated at month 12 to assess longer-term effects of the intervention.DISCUSSION:
This novel approach for enhancing an evidence-based BWL program with culturally-targeted stress management strategies for Black females addresses an understudied barrier to effective weight management among a population at high risk for obesity and obesity-related chronic diseases. This study will potentially elucidate psychological or behavioral mechanisms linking our novel intervention to study outcomes. If the intervention is proven to be effective, this study will have significant clinical and public health implications for weight management among Black females.
