Abstract

Introduction

According to the 2015-2016 National Health and Nutrition Examination Survey (NHANES), the national adult obesity rate was 40% with the incidence of adult obesity having increased by 70% over the last 30 years. Paralleling the obesity epidemic have been worsening sleep deprivation and eroding sleep quality. We analyzed data from a Cardiovascular Health Registry to explore a link between total sleep time and obesity.

Methods

Registry participants underwent anthropometrics and completed validated questionnaires assessing health behaviors and symptoms including total sleep time (TST), Epworth Sleepiness Scale (ESS), Fatigue Severity Scale (FSS), Pittsburgh Sleep Quality Index (PSQI), Perceived Stress Scale (PSS), and exercise time. Differences between subjects with sufficient (≥7 hours) and insufficient (<7 hours) sleep were analyzed using T-tests.

Results

Registry participants (n=630) had mean age 55.3±9.9 years (45% men, 391W, 182B, 26H, 12A, 19O). The subgroup with sufficient sleep (n=261, 48% men), had mean BMI 29.3±5.6 while the subgroup with insufficient sleep (n=369, 44% men) had mean BMI of 30.5±5.3, p=0.008. The insufficient sleep group was noted to be sleepier (ESS 9.7±4.9 vs 7.4±4.6, p<0.001), more fatigued (FSS 4.9±2.3 vs 3.5±2.4, p<0.001) and have worse sleep quality (PSQI 8.6±3.7 vs 4.7±2.8, p<0.001). Insufficient sleepers also perceived greater stress levels (PSS 22.2±8.4 vs 18.9±6.2, p<0.001), and showed a trend toward less exercise per week (143±134 vs 163±106 minutes, p=0.13).

Conclusion

Participants with insufficient sleep were significantly more overweight on average and were more symptomatic for insufficient sleep. While current approaches to weight management focus largely on diet and physical activity, the data from this study suggest that insufficient sleep should also be considered as a risk factor for obesity and should be incorporated into management plans for obesity.

1034我们应该建议多睡些以预防肥胖吗？

摘要

介绍

根据2015-2016年全国健康与营养检查调查（NHANES），全国成人肥胖率为40％，过去30年中成人肥胖的发生率增加了70％。与肥胖症流行并行的是，睡眠不足状况恶化，睡眠质量下降。我们分析了来自心血管健康注册中心的数据，以探索总睡眠时间与肥胖之间的联系。

方法

注册表参与者进行了人体测量学并完成了有效的问卷调查，评估了健康行为和症状，包括总睡眠时间（TST），爱泼华嗜睡量表（ESS），疲劳严重程度量表（FSS），匹兹堡睡眠质量指数（PSQI），知觉压力量表（PSS），和运动时间。使用T检验分析睡眠充足（≥7小时）和睡眠不足（<7小时）的受试者之间的差异。

结果

登记参加者（n = 630）的平均年龄为55.3±9.9岁（男性45％，391W，182B，26H，12A，19O）。睡眠充足的亚组（n = 261，男性占48％），平均BMI为29.3±5.6，而睡眠不足的亚组（n = 369，男性为44％），BMI为30.5±5.3，p = 0.008。睡眠不足组的睡眠较困（ESS 9.7±4.9 vs 7.4±4.6，p <0.001），更疲劳（FSS 4.9±2.3 vs 3.5±2.4，p <0.001）且睡眠质量较差（PSQI 8.6±3.7） vs 4.7±2.8，p ＜0.001）。睡眠不足的人也感觉到更大的压力水平（PSS 22.2±8.4比18.9±6.2，p <0.001），并且显示出每周减少运动的趋势（143±134 vs 163±106分钟，p = 0.13）。

结论

睡眠不足的参与者的平均超重明显更多，并且睡眠不足的症状更明显。虽然目前的体重控制方法主要集中在饮食和身体活动上，但这项研究的数据表明，睡眠不足也应被视为肥胖的危险因素，应纳入肥胖管理计划中。
