ObjectiveTo evaluate a commercially available, structured short-term weight management program designed for adolescents with obesity delivered by nonhealth professionals.Study designA multisite parallel-group randomized controlled trial was conducted to evaluate a commercial 12-week lifestyle behavioral program in commercial weight management centers in Australia. Eligible participants (13-17 years, body mass index (BMI) z score â¥1.282 with no presenting morbidities) were randomized (nâ=â88) to intervention or wait-list, and the program was delivered by consultants at participating weight management centers. The primary outcome was change in BMI z score. Secondary outcomes included the psychometric variables quality of life, body-esteem, and self-esteem. Data was analyzed according to intention-to-treat principles.ResultsOf 74 participants who consented to enter the study, 66 provided baseline anthropometric data and 12-week data were available for 55 individuals (74%). A significantly greater decrease in BMI z score in the intervention group (nâ=â32) was observed when compared with the wait-list control group, mean difference (MD)â=ââ0.27âkg/m2; 95% CI, â0.37,â0.17; Pâ<â.001). Participants allocated to receive the lifestyle intervention reported a greater improvement in body esteem (MD = 1.7, 95% CI, 0.3, 3.1; Pâ=â.02) and quality of life (MDâ=â5.9, 95% CI, 0.9, 10.9; Pâ=â.02) compared with the wait-list control group.ConclusionsA structured lifestyle intervention delivered by a commercial provider in an adolescent population can result in clinically relevant weight loss and improvements in psychosocial outcomes in the short term. Further research is required to evaluate long-term outcomes.Trial registrationInternational Clinical Trials Registry: ISRCTN13602313.
