title: Body mass index in male and female children with pervasive developmental disorders.
abstract: BACKGROUND
  The aim of the present study was to evaluate body mass index (BMI) of children with a pervasive developmental disorder (PDD) attending two university clinics during the 1960-84 period.
  
  
  METHODS
  BMI derived from medical records of 83 consecutively admitted children with atypical autism and 115 children with Asperger syndrome were compared with the corresponding BMI percentiles in an age- and sex-matched reference population.
  
  
  RESULTS
  The BMI distribution of the boys, but not the girls, in both diagnostic categories was significantly lower than those of the age-matched reference populations. Approximately 15% of the boys had a BMI below the fifth percentile.
  
  
  CONCLUSIONS
  The present findings are comparable to the results of other studies. Particular attention is given to low BMI as a potential endophenotype in boys with PDD.
