Association of daytime napping with prediabetes and diabetes in a Chinese population: Results from the baseline survey of the China Health and Retirement Longitudinal Study
中国人群午睡与前驱糖尿病和糖尿病的关系研究:来自中国健康与养老追踪调查的基线调查结果
Abstract
enBackground
Only a few studies have investigated the effects of daytime napping on diabetes, and these studies have reported conflicting results. The aim of the present study was to examine whether daytime napping is associated with a higher risk of prediabetes and diabetes.
Methods
The present cross-sectional study of napping duration in relation to prediabetes and diabetes was conducted in 12 277 participants. Data from the first wave (2011) of the China Health and Retirement Longitudinal Study were used. Daytime napping was divided into four groups: no napping (reference) and napping for 1–30, 31–90, and >90 min. Multinomial logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs).
Results
Individuals who reported taking daily afternoon naps accounted for 53.39% of all participants. Nappers had a higher prevalence of prediabetes and diabetes than non-nappers. Compared with the reference group, the weighted fully adjusted ORs (95% CI) were 1.36 (1.10–1.68) and 1.61 (1.22–2.13) for napping >90 min in prediabetic and diabetic patients, respectively.
Conclusions
Long daytime napping duration was positively associated with prediabetes and diabetes. Further physiological and cohort studies are needed to confirm these results and elucidate potential mechanisms.
摘要
zh背景
只有少数研究调查过午睡对糖尿病的影响, 并且这些研究的结果不一致。本研究旨在探究午睡是否与更高的前驱糖尿病和糖尿病患病风险有关。
方法
本研究是调查午睡时间与前驱糖尿病和糖尿病关系的横断面研究, 共12277名参与者。所用数据来自于中国健康与养老追踪调查的第一次全国基线调查(2011)。午睡者被分为四组:不午睡(参照组)和午睡时间为1-30,31-90, 以及> 90分钟。用多分类logistic回归来计算优势比(ORs)和95%置信区间(CIs)。
结果
每天午睡的人占全部参与者的53.39%。相比于不午睡者, 午睡者有更高的前驱糖尿病和糖尿病患病率。相比于参照组, 午睡> 90分钟时, 前驱糖尿病和糖尿病的加权校正后ORs(95% CIs)分别为1.36(1.10–1.68)和1.61(1.22–2.13)。
结论
长时间的午睡与前驱糖尿病及糖尿病呈正相关。还需要进一步的生理学研究和队列研究来证实这些结果, 并阐明潜在的机制。
