title: Atypical antipsychotic weight gain: a major clinical challenge.
abstract: OBJECTIVE
  The major aim of this paper is to review findings from weight management intervention studies to consider clozapine and/or olanzapine induced weight gain. A parallel aim is to summarize the challenges facing future research and provide an overview of best practice in the management of weight in mental health patients.
  
  
  METHODS
  A systematic literature search was conducted using Medline, Cinahl and PsychINFO data bases and reference lists from relevant published articles. Five studies which reported weight control practices in patients taking atypical antipsychotic medications were located and reviewed.
  
  
  RESULTS
  The studies reviewed provide some important descriptive clinical insights; however, common shortcomings include small subject numbers and methodological drawbacks such as lack of a control group.
  
  
  CONCLUSIONS
  There is some evidence that weight gain associated with atypical antipsychotic medication can be ameliorated by lifestyle changes such as improved nutritional practices and increased physical activity. Lifestyle interventions for individuals with psychotic disorders may need to be adapted to be most effective; for example, using strategies to counter increased appetite and to enhance physical activity. Clinicians need to be vigilant and persistent in monitoring and intervening if weight gain occurs. A standardized screening tool and clinical pathway would help clinicians to target appropriate interventions for each person prescribed atypical antipsychotic medication.
