Association Of Sleep Duration And Sleep Quality Withcommon Chronic Diseases: A Cross-sectional Study

Objectives:1. To better understand the sleep status and the prevalence of the chronic diseases in Huashan area, Maanshan; 2. Explore the relationship between sleep duration and sleep quality and chronic diseases, so as to provide theoretical foundation for improving the effect of chronic diseases prevention and control, which focus on improving sleep quality.Methods:1. A total of 2624 aged 18 and older people from Huashan area were sampled. 2. Uniform questionnaire and body measures were investigated for general condition, sleep status and the prevalence of chronic diseases. 3. Pittsburgh Sleep Quality Index(PSQI) was used to assess the sleep quality of respondents. 4. Epi Data3.1 and SPSS 16.0 were used to statistically descriptive analysis. Among this, Median(P25-P75) and nonparametric test were used to compare quantitative data. Spearman correlate and Binary Logistic Regression were applied to explore the relationship between sleep duration and sleep quality and chronic diseases.Results:1. The prevalence of hypertension, diabetes, dyslipidemia, coronary heart disease(CHD) and stroke was 19.74%、7.47%、6.10%、1.79% and 1.49%, respectively. 2. Among 2624 respondents, 186(7.09%) had poor sleep quality and 2438(92.9%) had good sleep quality. The PSQI score in female was higher than in male(Z=-3.456, P=0.001). The PSQI score of the group of hypertension, diabetes, dyslipidemia, CHD and stroke was higher than those without hypertension(Z=-5.966, P<0.001), diabetes(Z=-2.858, P=0.004), dyslipidemia(Z=-5.212, P<0.001), CHD(Z=-5.268, P<0.001) and stroke(Z=-3.284, P=0.001). 3. Correlate results between PSQI score and chronic diseases, there was a positive and negative correlation between sleep latency and sleep duration and hypertension, diabetes, dyslipidemia and CHD(P<0.01), respectively. There was a positive correlation between sleep quality, sleep efficiency, sleep disturbance and PSQI score and hypertension, diabetes, dyslipidemia, CHD and stroke(P<0.01). 4. Multivariate Logistic Regression results showed that only sleep quality and sleep duration aspect entered in the final equation of hypertension; sleep latency and sleep efficiency entered in the final equation of dyslipidemia; only use of hypnotic agents aspect entered in the final equation of stroke; only sleep quality aspect entered in the final equation of CHD. 5. Only shorter sleep duration and poor sleep quality couldn’t increase the risk of hypertension, diabetes and stroke, but could increase the risk of CHD; only shorter sleep time could increase the risk of dyslipidemia, but only poor sleep quality couldn’t. 6. Interaction effect of sleep duration and sleep quality on chronic diseases showed that too short sleep time merged with moderate or poor sleep quality could increase the risk of hypertension; shorter sleep duration merged with moderate sleep quality could increase the risk of dyslipidemia; longer sleep duration merged with poor sleep quality could increase the risk of CHD.Conclusions:1. The highest prevalence of adults’ was hypertension, followed by dyslipidemia, diabetes, CHD and stroke. 2. There existed sleep problems in community adults. 3. There existed a correlation between sleep duration and sleep quality and the risk of chronic diseases. And the interaction effect of sleep duration and sleep quality could increase the risk of hypertension, dyslipidemia and CHD.
