Efficacy of Lifestyle Interventions and Metformin for the Treatment of Antipsychotic-Induced Weight Gain
Lifestyle intervention and certain medications have been shown to be effective for antipsychotic-induced weight gain, but no controlled studies have compared psychological and pharmacological therapies. We conducted a randomized, placebo-controlled study to test the efficacy of lifestyle intervention and metformin alone and in combination for antipsychotic-induced weight gain.
Central South University has indicated that access to an investigational treatment associated with this study is available outside the clinical trial.

- body weight, body mass index, waist circumference, fasting glucose, fasting insulin, insulin resistance index
|Study Start Date:||October 2004|
|Study Completion Date:||December 2006|
The study was designed as a double-blind randomized controlled trial, with research assessors and patients intended to be blind to the intervention status. The staff members performing the assessment were not involved in implementing any aspect of the intervention.128 patients were randomized to one of four 12-week individual treatments: metformin (750mg/day), placebo, lifestyle intervention plus metformin (750mg/day) or lifestyle intervention plus placebo. Medications were provided in double-blind fashion.The assessments include body weight, body mass index, waist circumference, fasting glucose, fasting insulin and insulin resistance index.
