Are diet, physical activity, and behavioral interventions effective in helping overweight and obese children lose weight?
Interventions that include combinations of diet, physical activity, and behavior changes may reduce weight, body mass index (BMI), and BMI z-score (equivalent to BMI-for-age percentile) in overweight and obese children six to 11 years of age. These reductions are small and short term, however, and further studies are needed to determine the sustainability of these effects.1 (Strength of Recommendation: C, based on consensus, disease-oriented evidence, usual practice, expert opinion, or case series.)
In the United States, 16% of children and adolescents two to 19 years of age are overweight (defined as age- and sex-specific BMI in the 85th to 94th percentile), whereas 17% are obese (BMI in the 95th percentile or greater).2 Childhood obesity leads to adult obesity and is associated with a higher risk of respiratory, metabolic, and psychosocial conditions throughout the life span.3–6 The purpose of this Cochrane review was to identify effective behavioral interventions to help at-risk children lose weight.1
This updated systematic review included 70 randomized controlled trials with 8,461 participants, all of whom were six to 11 years of age. Most of the studies were conducted in high-income countries, with nearly one-half in the United States. Settings included subspecialist, primary care, and community-based interventions, and ranged from six months to three years. Thirty-two studies included children who were overweight or obese at baseline, 26 studies included only children who were obese, and five studies included only children who were overweight.
Study interventions included combinations of behavioral therapy, diet, and physical activity, and were provided or recommended by registered dietitians, therapists, or psychologists. Primary outcomes included changes in measured weight, BMI, and BMI
