[Association between sleep and prevalence of hypertension in elderly population].

Objective: To explore the association between sleep duration, sleep quality and the prevalence of hypertension in the elderly aged 65 years and above. Methods: This study was conducted among the elderly in communities in Yiwu, China from April to July, 2019, and participants were recruited through physical examination in the hospital. Face-to-face interview was performed to obtain basic information. Sleep duration and sleep quality were evaluated by Pittsburgh Sleep Quality Index (PSQI). Associations between sleep duration, sleep quality and hypertension were evaluated by multivariate logistic regression analysis. Results: A total of 3 169 elderly persons, aged ≥65 years old, were included in the study. The overall prevalence of hypertension was 50.8%. The elderly with very poor sleep quality and short sleep duration accounted for 22.4% and 28.5%, respectively. After adjusting for demographic characteristics, socioeconomic status, lifestyle and health status, the OR of hypertension for the elderly with very poor sleep quality was 1.42 (95%CI: 1.12-1.80) compared with those with very good sleep quality. Compared with the elderly with sleep duration of 6-7 h a night, the OR of hypertension for those with sleep duration <6 h was 1.37 (95%CI: 1.15-1.65). As the sleep quality decreased, the risk for hypertension increased. An U-shaped association was found between sleep duration and risk of hypertension. Subgroup analyses showed that this association existed in both men and women, but only significant in the elderly aged <75 years. Conclusion: Poor sleep quality and short sleep duration were associated with risk for hypertension in the elderly.目的： 研究社区≥65岁老年人睡眠质量、睡眠时间与高血压患病率之间的关联。 方法： 纳入2019年4-7月在浙江省义乌市参加健康体检的≥65岁老年人，通过问卷调查收集基本信息，睡眠质量和睡眠时间采用通用量表匹兹堡睡眠质量指数量表进行评估。采用多因素logistic回归分析睡眠质量、睡眠时间与高血压患病率之间的关联。 结果： 研究共纳入3 169名≥65岁老年人，高血压总体患病率为50.8%。睡眠质量很差者、睡眠时间短者分别占22.4%和28.5%。在调整人口学特征、社会经济状况、生活方式和健康状况之后，与睡眠质量很好者相比，睡眠质量很差者患高血压的OR值（95%CI）为1.42（1.12~1.80）；与睡眠时间为6~7 h者相比，睡眠时间<6 h的OR值（95%CI）为1.37（1.15~1.65）。随睡眠质量指数逐渐增加即睡眠质量降低，高血压患病风险逐渐上升，而睡眠时间与高血压患病风险呈现“U”形关系；亚组分析显示以上关联在男、女性中均存在，在<75岁老年人中有统计学意义。 结论： 睡眠质量、睡眠时间与高血压患病风险相关。.
