Objective To investigate the status and influencing factors of insufficient sleep among adult residents in Anhui province, and to provide evidences for improving the residents′ sleep quality.
Methods With stratified multistage cluster random sampling, we conducted face-to-face interviews among 7 344 permanent adult residents (at ages of 18 years and above) recruited at 12 disease surveillance points in Anhui province during October – December 2018. A self-designed questionnaire was used to collect the residents′ information on sleep duration and its associates; the prevalence of insufficient sleep (less than 7 hours per day) and its influencing factors were assessed using complex weighting and post-weighted stratification and logistic regression analysis.
Results Among 7 253 respondents with complete information, the average sleep duration was 7.5 hours per day and insufficient sleep was reported by 24.5% (2 240) of the respondents. Unconditional multivariate logistic regression analysis showed that aged ≥ 45 years and with a general or poor/very poor self-rated health condition are risk factors for insufficient sleep; while the education of junior high school and above is a protective factor.
Conclusion The prevalence of insufficient sleep was high and mainly influenced by age, education and self-rated health status among adult residents in Anhui province.
