Effect of folic acid and metformin on insulin resistance and inflammatory factors of obese children and adolescents.

Background: Considering the increasing trend of obesity, especially in developing countries such as Iran, and the role of inflammatory factors and insulin resistance (IR) in the occurrence of obesity-related complications as well as the safety of some agents such as folic acid and metformin, this clinical trial was designed to investigate the effect of metformin and folic acid on inflammatory factors and IR among obese children.

Materials And Methods: In this randomized, double-blind, controlled clinical trial study, sixty obese children aged 6-12 years were enrolled. Selected obese children were randomly allocated in two interventional (1 mg/daily folic acid or 1000 mg metformin for 8 weeks) groups.
