title: Parental history of type 2 diabetes in patients with nonaffective psychosis.
abstract: BACKGROUND
  We attempted to replicate two previous studies which found an increased risk of diabetes in the relatives of schizophrenia probands.
  
  
  METHODS
  N=34 patients with newly-diagnosed nonaffective psychosis and N=52 non-psychiatric controls were interviewed for parental history of Type 2 diabetes.
  
  
  RESULTS
  In a logistic regression model that included multiple potential confounders, psychosis was a significant predictor of Type 2 diabetes in either parent (p<0.04).
  
  
  CONCLUSIONS
  We found an increased prevalence of Type 2 diabetes in the parents of nonaffective psychosis subjects. This association may be due to shared environmental or genetic risk factors, or both.
