A new study has shown metformin—a glucose-lowering drug commonly used to treat diabetes—to be effective at lowering some measures of obesity in children and adolescents. The results of a systematic review and meta-analysis are published in Childhood Obesity.

The article entitled “Metformin Therapy Reduces Obesity Indices in Children and Adolescents: A Systematic Review and Meta-analysis of Randomized Clinical Trials” was coauthored by Alireza Milajerdi, Tehran University of Medical Sciences (Iran) and colleagues from Tehran University of Medical Sciences and University of Utah (Salt Lake City). The researchers searched the medical literature for randomized clinical trials that examined the effects of metformin use on obesity measures in children and adolescents. Overall, they found significant reductions in body mass index (BMI), body weight, waist circumference, and fat mass, but not in lean body mass. However, the reductions in BMI and waist circumference were not significant in the youngsters who were overweight or obese.
