摘要

背景：工作日/周末的睡眠时间失调（即社交时差）在青少年中尤为普遍，而且似乎与他们的身体健康有关。然而，关于这一主题的文献很少。因此，本研究旨在探讨西班牙青少年社会时差与身体健康的关系。方法：对来自西班牙穆尔西亚地区（Valle de Ricote）的812名12-17岁青少年（54.9%为女孩）的健康饮食和日常生活活动（EHDLA）研究的横截面数据进行二次分析。社交时差是根据自我报告的工作日和周末的就寝时间和起床时间计算出来的。身体健康通过儿童和青少年的身体活动和健康水平评估（ALPHA-FIT）进行评估，包括心肺健康、肌肉健康、速度敏捷性和灵活性。结果：分析显示，社交时差加重与整体身体健康受损之间存在显著负相关(非标准化系数[B] = -0.06, 95%可信区间[CI]: -0.09, -0.02；p = 0.002)、心肺适能(B = -1.28；95% ci -2.22, -0.34；p = 0.008)，下体肌肉适能(B = -2.01；95% ci -3.90, -0.12；P = 0.038)，校正了潜在协变量（年龄、性别、社会经济地位、身体活动水平、久坐行为、夜间睡眠时间、能量摄入和体重指数）。与其他健康成分相比，社交时差与速度敏捷性呈显著正相关(B = 0.07；95% ci 0.00, 0.14；p = 0.049)。结论：在青少年中，社交时差与较差的身体健康显著相关，尤其是心肺健康和下半身肌肉健康。保持规律和同步的睡眠对于优化身体健康和防止青春期身体素质下降至关重要。

Is Social Jetlag Associated With Physical Fitness Among Spanish Adolescents? Insights From the EHDLA Study

Background

The misalignment of sleeping times during weekdays/weekends (i.e., social jetlag) is particularly common among adolescents and plausibly associated with their physical fitness. However, literature on this topic is scarce. Therefore, this study aimed to investigate the association between social jetlag and physical fitness in Spanish adolescents.

Methods

A secondary analysis was conducted on cross-sectional data from the Eating Healthy and Daily Life Activities (EHDLA) study among 812 adolescents (54.9% girls) aged 12–17 years from the Valle de Ricote (Region of Murcia, Spain). Social jetlag was calculated from self-reported data on bedtimes and wake times for weekdays and weekends. Physical fitness was evaluated with the Assessing the Levels of PHysical Activity and Fitness (ALPHA-FIT) for children and adolescents and included cardiorespiratory fitness, muscular fitness, speed agility, and flexibility.

Results

The analysis revealed significant negative associations between worse social jetlag and detrimental overall physical fitness (unstandardized beta coefficient [B] = −0.06, 95% confidence interval [CI]: −0.09, −0.02; p = 0.002), cardiorespiratory fitness (B = −1.28; 95% CI −2.22, −0.34; p = 0.008), and lower body muscular fitness (B = −2.01; 95% CI −3.90, −0.12; p = 0.038) after the adjustment for potential covariates (age, sex, socioeconomic status, physical activity level, sedentary behavior, nocturnal sleep duration, energy intake, and body mass index). In contrast with other fitness components, a significant positive association was identified between social jetlag and speed agility (B = 0.07; 95% CI 0.00, 0.14; p = 0.049).

Conclusions

In adolescents, social jetlag is significantly linked to poorer physical fitness, especially for cardiorespiratory fitness and lower-body muscular fitness. Maintaining regular and well-synchronized sleep could be crucial for optimizing physical health and preventing the decline of physical fitness during adolescence.

期刊介绍： The American Journal of Human Biology is the Official Journal of the Human Biology Association. The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field. The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology. Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification. The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
