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.
