Abstract

PURPOSE

To examine associations of daytime napping and diagnosed diabetes in middle-aged premenopausal, middle-aged postmenopausal, and older postmenopausal Chinese women.

DESIGN

Quantitative, cross-sectional.

SETTING

2015 cross-sectional data from China Health and Retirement Longitudinal Study. Participants were recruited from 150 counties/districts and 450 villages/resident committees.

PARTICIPANTS

Six thousand nine hundred and forty women aged 45 years and older (mean age = 61 years) stratified by age and menopausal status.

MEASURES

The outcome was self-reported diagnosed diabetes. The exposure was self-reported daytime napping (0, >0-≤60, or >60 min/d). Participants were stratified to middle-aged premenopausal, middle-aged postmenopausal, and older postmenopausal women according to their age (≤60 or >60 years) and menopausal status.

ANALYSIS

One-way analysis of variance and χ tests were conducted to explore differences on characteristics of middle-aged premenopausal, middle-aged postmenopausal, and older postmenopausal women. Multiple logistic regressions were used to estimate adjusted odds ratios (ORs) for diagnosed diabetes according to daytime napping in the total sample, middle-aged premenopausal, middle-aged postmenopausal, and older postmenopausal Chinese women.

RESULTS

Participants' mean self-reported daytime napping duration was 34 minutes. Women who napped more than 60 minutes were more likely to report diagnosed diabetes (OR = 1.39, 95% confidence interval (CI), 1.09-1.76) comparing to those who did not nap, after adjusting for potential confounders. No statistical significance of interaction term between daytime napping and age/menopausal status was detected ( = .602 and = .558) among total women. The stratified analysis revealed the significant association among middle-aged postmenopausal women napping more than 60 minutes (OR = 1.81, 95% CI, 1.18-2.77). The association, however, was found to be insignificant in middle-aged premenopausal women and older postmenopausal women.

CONCLUSIONS

Long daytime nap (>60 min/d) was associated with diagnosed diabetes in middle-aged postmenopausal women in China.

摘要

目的

研究中国中年绝经前、中年绝经后及老年绝经后女性白天小睡与确诊糖尿病之间的关联。

设计

定量横断面研究。

背景

来自中国健康与养老追踪调查2015年的横断面数据。参与者从150个县/区和450个村/居民委员会招募。

参与者

6940名45岁及以上（平均年龄=61岁）的女性，按年龄和绝经状态分层。

测量指标

结局为自我报告的确诊糖尿病。暴露因素为自我报告的白天小睡情况（0、>0至≤60或>60分钟/天）。参与者根据年龄（≤60或>60岁）和绝经状态被分为中年绝经前、中年绝经后和老年绝经后女性。

分析

进行单因素方差分析和χ检验，以探讨中年绝经前、中年绝经后和老年绝经后女性特征的差异。采用多因素逻辑回归来估计总样本、中年绝经前、中年绝经后和老年绝经后中国女性中根据白天小睡情况确诊糖尿病的调整优势比（OR）。

结果

参与者自我报告的平均白天小睡时长为34分钟。与不午睡的女性相比，午睡超过60分钟的女性在调整潜在混杂因素后更有可能报告确诊糖尿病（OR=1.39，95%置信区间（CI），1.09-1.76）。在所有女性中，未检测到白天小睡与年龄/绝经状态之间交互项的统计学意义（P=.602和P=.558）。分层分析显示，中年绝经后女性午睡超过60分钟存在显著关联（OR=1.81，95%CI，1.18-2.77）。然而，在中年绝经前女性和老年绝经后女性中，该关联不显著。
