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

Purpose To describe the prevalence and clinical correlates of insomnia in schizophrenia patients treated in primary care. Design and Methods Six hundred and twenty-three schizophrenia patients from 22 primary care services were recruited. Findings 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. Practice Implications Insomnia is common in Chinese patients with schizophrenia treated in primary care and the rate of treatment appears low.
