BACKGROUND
The relationship between sleep duration and physical fitness is one aspect of sleep health. Potential factors associated with sleep duration interfere with physical fitness performance, but the impact trends on physical fitness indicators remain unclear.
METHODS
This study examined associations between sleep duration and physical fitness among young to middle-aged adults in Taiwan. A total of 42,781 Taiwanese adults aged 23-45 participated in the National Physical Fitness Examination Survey 2013 (NPFES-2013) in Taiwan between October 2013 and March 2014. A standardized structural questionnaire was used to record participants' sleep duration, which was stratified as short (< 6 h/day (h/d)), moderate (6-7 h/d; 7-8 h/d; 8-9 h), and long (≥ 9 h/d) sleep duration groups. Physical fitness was assessed based on four components: body composition (body mass index [BMI], waist-to-height ratio [WHtR], and waist-to-hip ratio [WHR]), muscle strength and endurance (1-min bent-leg sit-up test [BS]), flexibility (sit-and-reach test [SR]), and cardiorespiratory endurance index (3-min step test [CEI]).
RESULTS
By using analysis of covariance (ANCOVA), after sex grouping and age adjustment, we observed that sleep duration was significantly associated with obesity, functional fitness, and self-perception of health. The sleep duration for low obesity-related values (BMI, WHtR, and WHR) for men was 7-9 h/d, and that for women was 7-8 h/d. Sleeping more than 8 h/d showed poor functional fitness performances (BS and SR). For both sexes, sleep duration of 8-9 h/d was the optimal sleep duration for self-perceptions of health.
CONCLUSIONS
Our research found that there were wide and different associations of sleep duration with physical fitness and self-perception of health among Taiwanese adults aged 23-45, and there were differences in these associated manifestations between men and women. This study could be of great importance in regional public health management in Taiwan, and provide inspirations for clinical research on physical fitness.
背景
睡眠时长与身体健康之间的关系是睡眠健康的一个方面。可能与睡眠时长相关的因素会干扰身体健康表现，但对于身体健康指标的影响趋势仍不清楚。
方法
本研究调查了在台湾的年轻至中年成年人中，睡眠时长与身体健康之间的关联。共有 42781 名 23-45 岁的台湾成年人参与了 2013 年台湾全国体质健康检查调查（NPFES-2013），调查时间为 2013 年 10 月至 2014 年 3 月。使用标准化结构问卷记录参与者的睡眠时长，将其分层为短（<6 小时/天（h/d））、中（6-7 h/d；7-8 h/d；8-9 h/d）和长（≥9 h/d）睡眠时长组。根据四个组成部分评估身体健康：身体成分（体重指数 [BMI]、腰高比 [WHtR] 和腰臀比 [WHR]）、肌肉力量和耐力（1 分钟屈腿仰卧起坐测试 [BS]）、柔韧性（坐立前伸测试 [SR]）和心肺耐力指数（3 分钟踏步测试 [CEI]）。
结果
使用协方差分析（ANCOVA），在按性别分组和年龄调整后，我们观察到睡眠时长与肥胖、功能性健康和自我健康感知显著相关。男性低肥胖相关值（BMI、WHtR 和 WHR）的睡眠时长为 7-9 h/d，女性为 7-8 h/d。睡眠时间超过 8 h/d 显示出较差的功能性健康表现（BS 和 SR）。对于男性和女性，8-9 h/d 的睡眠时间是自我健康感知的最佳睡眠时间。
结论
我们的研究发现，台湾 23-45 岁成年人的睡眠时长与身体健康和自我健康感知之间存在广泛而不同的关联，并且这些关联表现存在性别差异。本研究对台湾地区公共卫生管理具有重要意义，并为身体健康的临床研究提供了启示。
