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.
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).
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.
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.
仅有少数研究调查了日间小睡对糖尿病的影响，这些研究的结果相互矛盾。本研究旨在探讨日间小睡是否与糖尿病前期和糖尿病的风险增加有关。
本研究为关于日间小睡持续时间与糖尿病前期和糖尿病关系的横断面研究，共纳入了 12277 名参与者。研究数据来自中国健康与养老追踪调查的第一波（2011 年）。日间小睡分为四组：不午睡（参考组）和午睡 1-30 分钟、31-90 分钟和>90 分钟。使用多分类逻辑回归获得比值比（ORs）和 95%置信区间（CI）。
报告每天下午午睡的个体占所有参与者的 53.39%。与不午睡者相比，午睡者的糖尿病前期和糖尿病患病率更高。与参考组相比，午睡>90 分钟的糖尿病前期和糖尿病患者的加权完全调整后 OR（95%CI）分别为 1.36（1.10-1.68）和 1.61（1.22-2.13）。
长时间的日间小睡与糖尿病前期和糖尿病呈正相关。需要进一步的生理和队列研究来证实这些结果并阐明潜在的机制。
