The prevalence of sleep problems and their socio-demographic and clinical correlates in young Chinese rural residents

This study aimed to determine the prevalence of basic forms of sleep disturbance (DIS: difficulty initiating sleep; DMS: difficulty maintaining sleep; and EMA: early morning awakening) as well as insomnia (defined as sleep disturbance accompanied by distress or daily functioning impairment), their socio-demographic and clinical correlates, and the treatment patterns in young Chinese rural people. A sample of 1642 subjects was recruited in Mianyang and interviewed using standardized instruments. Basic socio-demographic and clinical data were collected. The prevalence of at least one type of reported sleep disturbance was 8.0%, while the prevalence of at least one type of insomnia was 2.7%. In multivariate analyses, age between 30 and 34 years, having psychiatric disorders, poorer physical domain of quality of life (QOL), better social QOL domain, depressive symptoms and lower social support were independently associated with more frequent sleep disturbance. At the same time, age between 30 and 34 years, female sex, poorer physical QOL domain, better social QOL domain, depressive symptoms, lower life satisfaction, lower social support and more life events were independently associated with more frequent insomnia. Self-reported sleep disturbances are common among young Chinese residents. The low percentage of treated community residents might suggest a need to promote accessible and easily implemented interventions. (C) 2012 Elsevier Ireland Ltd. All rights reserved.
