Comparing active pediatric obesity treatments using meta-analysis.

The current meta-analysis reviews research on the treatment of pediatric obesity focusing on studies that have been published since 1994. Eleven studies (22 comparisons, 115 effect sizes, N = 447) were included in the present meta-analysis. Results indicated that comprehensive behavioral interventions may be improved in at least two ways: increasing the "dose" of behavioral components and increasing parental involvement. Although limited to just one investigation, support for the use of medication was also found. The addition of cognitive therapy techniques did not appear to increase, and possibly detracted from, the efficacy of established treatments.
