“…The average 5.5 kg weight loss demonstrated by adolescents randomized to the CBT þ PEAT intervention at the end of treatment exceeds that observed in a number of previous behavioral weight control trials with this age group. [15][16][17][18] Additionally, CBT þ PEAT appeared particularly effective for the older adolescents in our sample. Older adolescents randomized to the peer intervention lost more than 7 kg compared to less than 2 kg for those in the CBT þ EXER condition.…”

‘Adventure therapy’ combined with cognitive-behavioral treatment for overweight adolescents

Objective: Since peers have such an important influence on adolescents, we evaluated the efficacy of adding peer-based 'adventure therapy' to a standard cognitive-behavioral weight control program for overweight adolescents. Methods: Adolescents (N ¼ 76) aged 13-16 years and 20 to 80% overweight (M ¼ 60.56%, s.d. ¼ 15.17%), were randomly assigned to one of two treatment conditions: cognitive-behavioral group treatment with 'adventure therapy' similar to Outward Bound s (cognitive-behavioral treatment with peer-enhanced adventure therapy (CBT þ PEAT)) or cognitive-behavioral group treatment with aerobic exercise (CBT þ EXER). Anthropometric and psychosocial measures were obtained at baseline, at the end of the 16-week intervention, and at 10 months following randomization. Results: Adolescents assigned to both treatment conditions demonstrated significant weight loss over time, F ¼ 29.06, df ¼ 2, 53, Po0.01. Average weight loss did not differ significantly between groups (À5.31 kg for CBT þ PEAT and À3.20 kg for CBT þ EXER) at the end of treatment. There was a significant difference in the percentage of participants maintaining a minimum 4.5 kg (10 pounds) weight loss (35% in the CBT þ PEAT condition vs 12% in the CBT þ EXER condition, P ¼ 0.042) 10 months from randomization. We also observed a significant age by treatment group interaction, such that older adolescents randomized to CBT þ PEAT demonstrated more than four times the weight loss of older adolescents assigned to CBT þ EXER (M ¼ À7.86 kg vs M ¼ À1.72 kg) at the end of treatment. Conclusions: Peer-based 'adventure therapy' is a promising adjunct to standard cognitive-behavioral weight control intervention for adolescents, and may be most effective for older adolescents.

“…Five RCTs have specifically assessed dietary interventions in adolescents [24,25,32,42,69]. Ikeda et al [42] found no difference between a calorie-reduced diet and a behavioural approach for weight loss. Sondike et al [69] reported that adolescents had better compliance and weight loss with a low carbohydrate diet compared with a low fat diet over 12 weeks.…”

Treatment of adolescent overweight and obesity

Adolescence is a vulnerable period for the development of obesity, and adolescent weight tracks strongly into adulthood. Previous reviews of treatment strategies have failed to discriminate between adolescents and children, thereby, disregarding the uniqueness of this population. Hence, this review aims to summarise the evidence for treatment approaches for adolescent obesity. Pubmed, OVID, EBSCOhost and Google Scholar were searched for randomised controlled trials, meta-analyses and systematic reviews testing treatments for overweight/obese adolescents (aged 12-19 years), published from 1982-2006 in English. Eligible studies had to assess either weight, percentage overweight, body mass index (BMI) or body fat. Thirty-four randomised controlled trials were eligible. The results of this review indicate that the safety and efficacy of surgical and pharmacotherapy treatments for adolescent obesity is uncertain. Diet and physical activity approaches may improve obese status in the short term. However, obesity interventions appear more effective when strategies are combined, rather than when used in isolation. Psychological interventions, such as behavioural and cognitive behavioural therapy, show promise in achieving the necessary lifestyle changes for obesity reduction; however, long-term follow-up studies are needed. There were multiple limitations in appraising the literature. Inconsistent definitions of overweight/obesity make comparisons between studies difficult. Many studies have not used direct adiposity measures, have failed to assess pubertal status or have not used an exclusive adolescent sample. We conclude that, despite these limitations, current evidence indicates that behavioural and cognitive behavioural strategies combined with diet and physical activity approaches may assist in reducing adolescent obesity,although long-term follow-up studies are needed.

“…Reviews of randomized treatment studies conducted with adolescents in outpatient settings indicate that weight losses typically range from 1 to 4 kg (5)(6)(7)(8). However, some studies have produced much larger weight losses (9,10).…”

Objective: To evaluate demographic and psychosocial predictors of attrition and weight loss in a behaviorally based adolescent weight control trial. Methods and Procedures: Adolescents (N = 76) aged 13-16 years and 20-80% overweight (M = 60.56%, s.d. = 15.17%) received standard group-based behavioral treatment as part of a randomized trial comparing different activity interventions for overweight adolescents. Anthropometric and psychosocial measures were obtained at baseline and after the 16-week intervention. Results: Higher parent (P < 0.01) and adolescent BMI (P < 0.05) at baseline, as well as ethnic minority status (P < 0.05) were significantly associated with attrition in univariate analyses. Parent BMI remained the only significant predictor of attrition in multivariate analyses. BMI change for completers (N = 62) was highly variable, ranging from -6.09 to +1.62 BMI units. Male gender (P < 0.01) was a significant predictor of reduction in BMI, whereas not being from an ethnic minority group (P < 0.05) and attendance at group sessions (P = 0.05) were associated with ≥5% absolute weight loss in multivariate analyses. Absolute weight loss during the first 4 weeks of the program was strongly associated with weight loss (pr = 0.44, P < 0.001) during the remainder of the intervention. Psychosocial variables were unrelated to attrition or treatment outcome. Discussion: These findings highlight the potential importance of attending to parental BMI in efforts to retain adolescent participants in treatment, as well as the need to develop weight control interventions that are more effective for ethnic minority youth.
