title: Obstetrical complications in children at high risk for bipolar disorder.
abstract: OBJECTIVE
  To examine obstetrical complications as a risk factor for developing bipolar disorder (BPD). We hypothesized that children with a bipolar parent would be at greater risk for obstetrical complications than demographically matched children of healthy adults. Additionally, within this "at-risk" (AR) sample, we hypothesized that obstetrical complications would be associated with the development of psychiatric disorders.
  
  
  METHODS
  The Washington University in St. Louis Kiddie-Schedule for Affective Disorders and Schizophrenia (WASH-U KSADS) was administered to children (AR) who had at least one parent with BPD (N=36) and children of healthy parents (HC) (N=27), by raters who were blind to diagnostic category. To assess obstetrical risk history, the Rochester Research Obstetrical Scale (ROS) was administered to parents of AR and HC children.
  
  
  RESULTS
  Children at familial risk for BPD had greater total (p=0.02) and prenatal (p=0.006) obstetrical complication scores than children of healthy parents. However, obstetrical complications were not associated with the development of affective, anxiety, or disruptive behavioral disorders within the at-risk group.
  
  
  CONCLUSIONS
  Our data suggest that compared with children of families without BPD, children of parents with BPD may be at greater risk for obstetrical complications, particularly those that occur during the prenatal period; however, at this early follow-up period factors other than obstetrical complications appear to contribute to the differences in rates of psychiatric disorders between these groups.
