N2  - OBJECTIVE: To estimate the prevalence of poor sleep quality and identify related factors by gender in the Chinese rural population. <br><br>METHODS: Overall, 27424 subjects (10881 males and 16543 females) aged 18-79 years were enrolled from the Henan Rural Cohort Study. Sleep quality was evaluated by the standard Pittsburgh Sleep Quality Index (PSQI) and global score>5 was classified as poor sleep quality. Logistic regression analysis was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). A meta-analysis including 14 studies was used to validate the result of the cross-sectional study. <br><br>RESULTS: The average PSQI score was 3.78 ± 2.72 in total, and the score of females (4.10 ± 2.90) was significantly higher than males (3.29 ± 2.33). The crude and age-standardized prevalences of poor sleep quality were 21.62% and 15.80%, respectively. The crude prevalence in females (25.73%) was significantly higher than males (15.38%). The results of meta-analysis showed that the pooled prevalence of poor sleep quality was 25.0% (18.8%-31.2%) in total sample, 31.7% (24.9%-38.5%) in male, and 38.2% (29.7%-46.7%) in females. Multivariate logistic regression identified that older age, being female, unmarried/divorced/widowed, low education level, low income, drinking, depression and dyslipidemia could increase the odds of poor sleep quality. <br><br>CONCLUSIONS: More than one fifth of the participants in a rural area of China slept poorly and the prevalence in females was significantly higher than males. Effective interventions are urgently needed to improve the sleep quality in resource limited areas.
