Prevalence of Insomnia and Clinical and Quality of Life Correlates in Chinese Patients With Schizophrenia Treated in Primary Care

PurposeTo describe the prevalence and clinical correlates of insomnia in schizophrenia patients treated in primary care. Design and MethodsSix hundred and twenty-three schizophrenia patients from 22 primary care services were recruited. FindingsThe 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. Practice ImplicationsInsomnia is common in Chinese patients with schizophrenia treated in primary care and the rate of treatment appears low.
