OBJECTIVE: The goal of this follow-up to a randomized proof-of-concept study was to determine if targeting body shape concern (BSC) has a clinically significant impact on long-term weight change among adult women of higher body weight with BSC. A secondary aim was to observe the maintenance of body image improvements during follow-up.
METHOD: In the original 4-week trial, women were randomized to behavioral weight loss recommendations alone (control; n = 15) or combined with the evidence-based body project intervention (n = 17). All participants were directed to continue monitoring diet and exercise through Week 8. The current analysis focused on follow-up data collected on weight, BSC, internalized weight bias, internalized thin ideal, and body appreciation at 8 weeks, 6 months, and 12 months. Percent weight change was calculated from baseline and compared against clinical milestones of -2.5% and -5%. An intent-to-treat approach was used for individuals lost to follow-up (n = 11).
RESULTS: Body project participants achieved the clinically significant target of -2.5% weight loss by 12 months. Control participants did not reach the milestone and regained lost weight at 12 months. Neither condition reached the 5% clinical target. Both groups experienced improved body image, but body project participants maintained a greater magnitude of improvement in all measures except internalized thin ideal at 12 months.
CONCLUSION: The current study provides preliminary evidence that targeting BSC among women with BSC who want to lose weight may improve long-term weight loss. Further intervention development and testing are warranted.
PUBLIC SIGNIFICANCE: The results of this study suggest that targeting negative body image among adult women with high BSC might be a pathway to improve long-term weight loss in behavioral weight management. This is aligned with precision medicine priorities to optimize weight-related health care.
