abstract: OBJECTIVE
  To describe the prevalence and clinical correlates of insomnia in schizophrenia patients treated in primary care.
  
  
  METHODS
  Six hundred and twenty-three schizophrenia patients from 22 primary care services were recruited.
  
  
  RESULTS
  The prevalence of at least one type of insomnia was 28.9% (180/623), while those of difficulty initiating sleep, difficulty maintaining sleep, and early morning wakening were 20.5%, 19.6%, and 17.7%, respectively. Only 53.3% of patients suffering from insomnia received treatment.
  
  
  CONCLUSIONS
  Insomnia is common in Chinese patients with schizophrenia treated in primary care and the rate of treatment appears low.
