Abstract：
Less is known about how compliance with 24-hour movement guidelines for physical activity (PA), sedentary behavior, and sleep affects adiposity in young people. The purposes of this study were to compare compliance with 24-hour movement guidelines in Asian adolescents and to examine the associations between compliance with 24-hour movement guidelines and body fat percentage. A sample of 12 590 adolescents aged 13.63 (± 1.01) years from eight Asian metropolitan cities including Bangkok (Thailand), Hong Kong SAR, Kuala Lumpur (Malaysia), Seoul (South Korea), Shanghai (China), Singapore, Taipei (Taiwan), and Tokyo (Japan) completed interviewer-administered questionnaires to assess moderate-to-vigorous PA, recreational screen time, sleep duration, and covariates. Body fat percentage was measured using bioelectrical impedance analysis. We found that compliance with 24-hour movement guidelines differed in Asian adolescents across the eight cities. Adjusting for covariates, there was a negative association between number of the guidelines being met and body fat percentage in Asian adolescents. In addition, meeting only the sleep guideline and both the PA and sleep guidelines had negative associations with body fat percentage compared with no guidelines being met. Our findings improve the understanding about how compliance with 24-hour movement guidelines benefit a healthy body weight in adolescents, as well as contribute to development of evidence-based 24-hour movement guidelines for Asian young people. Future research is needed to gain better insights into the directionality of the associations between compliance with 24-hour movement guidelines and adiposity, as well as the mechanisms underlying the associations in Asian adolescents.
摘要：
关于如何遵守24小时运动指南（PA），久坐的行为，睡眠会影响年轻人的肥胖。这项研究的目的是比较亚洲青少年对24小时运动指南的依从性，并检查对24小时运动指南的依从性与体脂百分比之间的关联。来自包括曼谷（泰国）在内的八个亚洲大都市的12.590名13.63（±1.01）岁的青少年样本，香港特别行政区,吉隆坡(马来西亚),首尔(韩国),上海(中国),新加坡,台北(台湾),和东京（日本）完成了面试官管理的问卷，以评估中度至剧烈的PA，娱乐屏幕时间，睡眠持续时间,和协变量。使用生物电阻抗分析测量体脂百分比。我们发现，八个城市的亚洲青少年对24小时运动指南的遵守情况有所不同。调整协变量，在亚洲青少年中,指南被满足的数量与体脂百分比呈负相关.此外,仅符合睡眠指南，PA和睡眠指南与体脂百分比呈负相关，而未符合任何指南。我们的发现提高了对遵守24小时运动指南如何有益于青少年健康体重的理解，以及有助于为亚洲年轻人制定基于证据的24小时运动指南。未来的研究需要更好地了解遵守24小时运动指南和肥胖之间的关系的方向性，以及亚洲青少年协会的潜在机制。
