To investigate the association between self-reported sleep duration, sleep quality and the prevalence of diabetes in a contemporary sample of Chinese adults.
Cross-sectional survey.
Community-based investigation in Xuzhou, China.
16 893 Chinese men and women aged 18-75 who fulfilled the inclusion and exclusion criteria were enrolled.
Self-reported quality and duration of sleep were obtained by questionnaire, and type 2 diabetes was assessed by fasting blood glucose. Sleep quality was categorised as good, common or poor. Sleep duration was measured by average hours of sleep per night, with categories of ≤6 h, 6-8 h and ≥8 h. A logistic regression model was used to evaluate the association between sleep duration or sleep quality and diabetes.
Both poor quality of sleep and short sleep duration (≤6 h) were associated with increased prevalence of diabetes, with higher rates in relatively healthy Chinese people. Compared with the group with good quality of sleep and 6-8 h sleep duration, diabetes was the most prevalent in individuals with poor sleep quality and ≤6 h sleep duration (OR 1.41, 95% CI 1.07 to 1.85) and in those with poor sleep quality who slept ≥8 h (OR 1.39, 95% CI 0.85 to 2.26), even after adjustment for a large number of further possible factors.
The results suggest that sleep of poor quality and short duration is associated with diabetes.
在当代中国成年人样本中，调查自我报告的睡眠时间、睡眠质量与糖尿病患病率之间的关联。
横断面调查。
中国徐州的社区调查。
纳入16893名年龄在18 - 75岁之间、符合纳入和排除标准的中国男性和女性。
通过问卷调查获取自我报告的睡眠质量和时长，通过空腹血糖评估2型糖尿病。睡眠质量分为良好、一般或较差。睡眠时间通过每晚平均睡眠时间衡量，分为≤6小时、6 - 8小时和≥8小时。采用逻辑回归模型评估睡眠时间或睡眠质量与糖尿病之间的关联。
睡眠质量差和睡眠时间短（≤6小时）均与糖尿病患病率增加相关，在相对健康的中国人中患病率更高。与睡眠质量良好且睡眠时间为6 - 8小时的组相比，睡眠质量差且睡眠时间≤6小时的个体（比值比1.41，95%置信区间1.07至1.85）以及睡眠质量差且睡眠时间≥8小时的个体（比值比1.39，95%置信区间0.85至2.26）糖尿病患病率最高，即使在进一步调整大量可能因素后也是如此。
结果表明，睡眠质量差和睡眠时间短与糖尿病有关。
