title: Health complaints in children with attention-deficit/hyperactivity disorder.
abstract: OBJECTIVE
  To assess recurrent subjective health complaints in Swedish schoolchildren with attention-deficit/hyperactivity disorder (ADHD).
  
  
  METHODS
  Cohort study of 577 fourth-graders (10-y-olds) in one municipality in Stockholm County. All children were screened for attention and behaviour problems through interviews with their parents and teachers. Children with high scores underwent further clinical and cognitive assessments. Information about health complaints was collected from the children themselves in a classroom questionnaire. The 516 children for whom there was information from all three data sources were included in the final study population. Hypotheses were tested in multivariate analyses with adjustment for sex and parental education.
  
  
  RESULTS
  Recurrent abdominal pain (RAP), sleeping problems and tiredness were associated with ADHD (stratified relative risks: 2.2 [1.4-3.4], 1.7 [1.1-2.7] and 2.7 [1.7-4.1], respectively), while there was no association with headache.
  
  
  CONCLUSIONS
  This study indicates that treatment strategies for children with ADHD need to include an effective evaluation and treatment of RAP, tiredness and sleeping disturbances. Evaluation of ADHD should be considered in children with recurrent health complaints.
