title: The effects of an educational intervention on antipsychotic-induced weight gain.
abstract: OBJECTIVE
  To assess the effect of an educational intervention on antipsychotic-induced weight gain among patients with schizophrenia.
  
  
  METHODS
  Quasi-experimental. Seventy patients with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder entered this 6-month study condicted in the United States. All participants began receiving olanzapine treatment when they entered the study. The patients were then randomly assigned to an intervention group or a standard care group. Over the next 4-months, the intervention group participated in weekly psychoeducation classes focused on nutrition, exercise, and living a healthy lifestyle. Patients were followed for an additional 2 months to assess weight change.
  
  
  RESULTS
  A statistically significant difference in weight change between the two groups was observed post-treatment and at endpoint. At endpoint, the mean weight change of the intervention group was -.06 pounds, while the mean weight change in the standard care group was 9.57 pounds. In both groups, men gained significantly more weight than did women.
  
  
  CONCLUSIONS
  The results indicate that a structured educational intervention might have a positive effect on antipsychotic-induced weight gain among patients with schizophrenia.
