Study objectives

Population-based studies on the association of objectively assessed physical activity (PA) with sleep among adolescents are rare. We examined this association by applying accelerometry and accounting for the day-by-day variability.

Methods

Accelerometers (Actigraph GT3X) were worn for one week by 1223 participants during the 15-year follow-up of the German birth cohorts (German infant study on the Influence of Nutrition Intervention plus air pollution and genetics on allergy development, GINIplus) and (Influence of Lifestyle factors on the development of the Immune System and Allergies in East and West Germany, LISA) to measure PA and sleep. PA was categorised into sedentary, lifestyle and moderate-to-vigorous physical activity (MVPA) referring to Sasaki and Romanzini. Sleep was analysed according to the algorithm developed by Sadeh. Sleep quality was represented by sleep efficiency (SE), sleep onset latency (SOL) and time awake per hour after sleep onset (TAPH). Sleep and activity were additionally reported by diaries. Linear and generalized mixed-effects-models with logit-link with subject specific random intercepts were used stratified by sex and adjusted for confounding variables.

Results

Physical activity appears to be associated only with sleep quality the following night. Among female participants, SE improved (β = 0.12 [95% CI = (0.05; 0.18)]) per 10 minutes increase of MVPA. SOL decreased (OR = 0.83 [95% CI = (0.69; 0.99)]) among male participants with at least 60 min of MVPA per day. Engaging in leisure sport MVPA was associated with higher SE among female (β = 0.70 [95% CI = (0.22; 1.17)]) and male participants (β = 0.76 [95% CI = (0.18; 1.34)]). Also, TAPH among female (β = −0.37 [95% CI = (−0.65; −0.09)]) and SOL among male subjects (OR = 0.70 [95% CI = (0.57; 0.85)]) decreased. Increasing lifestyle activity was related to longer SOL among female (OR = 1.36 [95% CI = (1.15; 1.62)]) and male subjects (OR = 1.32 [95% CI = (1.10; 1.58)]).

Conclusions

In this large population-based sample of German adolescents MVPA and leisure sport improved short term sleep quality, supporting regular PA in adolescents for their health benefit.

客观评估的体育活动与青春期睡眠质量之间的关联。GINIplus和LISA研究的结果。

学习目标

基于人群的关于青少年客观评估身体活动（PA）与睡眠之间关系的研究很少。我们通过应用加速度计并考虑了日常变化来检查了这种关联。

方法

在德国出生队列的15年随访中（营养干预加上空气污染和遗传学对过敏发展的影响的德国婴儿研究，GINIplus）和（影响），由1223名参与者在一周内将加速度计（Actigraph GT3X）戴了一周。生活方式因素对德国东部和西部免疫系统和过敏的发展（LISA）的影响，以测量PA和睡眠。PA分为久坐，生活方式和中度至剧烈运动（MVPA），是指Sasaki和Romanzini。根据Sadeh开发的算法分析了睡眠。睡眠质量由睡眠效率（SE），睡眠发作潜伏期（SOL）和睡眠发作后每小时清醒时间（TAPH）表示。日记还报告了睡眠和活动。

结果

次日晚上，体育锻炼似乎仅与睡眠质量有关。在女性参与者中，每10分钟MVPA升高，SE改善（β= 0.12 [95％CI =（0.05; 0.18）]。每天至少有60分钟MVPA的男性参与者的SOL降低（OR = 0.83 [95％CI =（0.69; 0.99）]）。从事休闲运动的MVPA与女性（β= 0.70 [95％CI =（0.22; 1.17）]）和男性参与者（β= 0.76 [95％CI =（0.18; 1.34）]）的SE较高有关。此外，女性（β= -0.37 [95％CI =（-0.65; -0.09）]中的TAPH和男性受试者（OR = 0.70 [95％CI =（0.57; 0.85）]）中的SOL降低。生活方式的增加与女性（OR = 1.36 [95％CI =（1.15; 1.62）]）和男性受试者（OR = 1.32 [95％CI =（1.10; 1.58）]）中较长的SOL相关。

结论

在这个基于人群的大量德国青少年样本中，MVPA和休闲运动改善了短期睡眠质量，为青少年的常规PA提供了健康益处。
