Intervention programs meant to help obese children lose weight can be effective, according to a recent review published in the Cochrane Database of Systematic Reviews.

Researchers at the University of Melbourne in Australia analyzed data from 55 studies that targeted children between 6 and 12 years of age. Their work confirmed that the obesity prevention programs were effective at reducing fat.

“We found strong evidence to support beneficial effects of child obesity prevention programs on BMI, particular for programs targeted to children aged 6 to 12 years,” the study authors said.

The study found no evidence of adverse outcomes such as unhealthy dieting or body weight sensitivities.
