title: The Prevalence of Insomnia, Its Demographic Correlates, and Treatment in Nurses Working in Chinese Psychiatric and General Hospitals.
abstract: OBJECTIVE
  To determine the prevalence of insomnia and its socio-demographic correlates in Chinese nurses.
  
  
  METHODS
  Up to 799 nurses were examined. Demographic data, total sleep time (TST), and insomnia were collected.
  
  
  RESULTS
  The mean expected and actual TST were 8.3 ± 1.5 and 6.1 ± 1.1 hr, respectively. The prevalence of at least one type of reported sleep disturbance was 69.7%; the rates of difficulty initiating sleep, difficulty maintaining sleep, and early morning awakening were 54.6%, 54.7%, and 55.9%, respectively.
  
  
  CONCLUSIONS
  There is a large discrepancy of actual and expected sleep duration, and insomnia is common among nurses in China.
