Previous studies have reported that sleep duration might increase the risk of hypertension. However, the results have been conflicting. We investigated whether sleep duration is independently associated with hypertension. We aimed to assess the relationship between sleep duration and hypertension in a population-based cross-sectional study.
In this study we used multistage stratified cluster sampling. A total of 19 407 adults aged 18-79 years were enrolled in the study. The participants were divided into three groups (<7 hours/day, 7-8 hours/day and >8 hours/day) according to self-reported sleep duration. Hypertension was defined as systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg or the use of anti-hypertensive medications. Univariate and multivariate logistic regressions were performed to determine the association between hypertension and sleep duration adjusted for sociodemographic, body mass index, and lifestyle covariates.
The overall prevalence of hypertension was 32.6%. Among participants aged 18-44 years, individuals sleeping less than 7 hours per day had a higher risk of hypertension (OR=1.24, 95% CI: 1.05 to 1.46), compared with those who slept 7-8 hours per day. There were no significant associations between sleep duration and hypertension in the total sample, among middle-aged adults (45-59 years) or older adults (60-79 years).
Our study demonstrates that short sleep duration was significantly associated with hypertension among people aged 18-44 years in northeast China.
既往研究报道睡眠时间过长可能增加高血压风险，但结果存在争议。本研究旨在探讨睡眠时间与高血压的相关性。我们旨在评估一项基于人群的横断面研究中睡眠时间与高血压的关系。
本研究采用多阶段分层聚类抽样方法，共纳入 19407 名 18-79 岁成年人。根据自我报告的睡眠时间将参与者分为三组（<7 小时/天、7-8 小时/天和>8 小时/天）。高血压定义为收缩压≥140mmHg 或舒张压≥90mmHg 或使用抗高血压药物。采用单因素和多因素逻辑回归分析睡眠时间与高血压的相关性，并调整了社会人口学、体重指数和生活方式等混杂因素。
高血压总患病率为 32.6%。在 18-44 岁的参与者中，与每天睡 7-8 小时的人相比，每天睡眠时间少于 7 小时的人患高血压的风险更高（OR=1.24，95%CI：1.05 至 1.46）。在总样本、中年（45-59 岁）或老年（60-79 岁）成年人中，睡眠时间与高血压之间无显著相关性。
本研究表明，在中国东北地区 18-44 岁人群中，短睡眠时间与高血压显著相关。
