title: The Prevalence of Sleep Disturbance and Its Socio-demographic and Clinical Correlates in First-episode Individuals With Schizophrenia in Rural China.
abstract: OBJECTIVE
  This study aimed to determine the prevalence and the socio-demographic and clinical correlates of sleep disturbance in first-episode individuals with schizophrenia in rural China and the factors that impact sleep among individuals with schizophrenia.
  
  
  METHODS
  A total of 104 first-episode individuals with schizophrenia were randomly selected in rural areas in Ningxia, China, in 2015 as the study sample.
  
  
  RESULTS
  In first-episode individuals with schizophrenia, the prevalence of sleep disturbance was 78.8% (82/104). Sleep disturbance was significantly associated with economic status, living situation, educational level, depressive symptoms, and anxiety symptoms.
  
  
  CONCLUSIONS
  Sleep disturbance is common in first-episode individuals with schizophrenia in rural China and more attention should be paid in clinical practice to improve the sleep quality for individuals with schizophrenia.
