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.
关于遵守 24 小时运动指南（包括体力活动、久坐行为和睡眠）对年轻人肥胖的影响，人们了解较少。本研究的目的是比较亚洲青少年遵守 24 小时运动指南的情况，并探讨遵守 24 小时运动指南与体脂百分比之间的关系。本研究纳入了来自亚洲 8 个大都市（包括泰国曼谷、中国香港特别行政区、马来西亚吉隆坡、韩国首尔、中国上海、新加坡、中国台北和日本东京）的 12590 名年龄在 13.63（±1.01）岁的青少年，他们完成了问卷调查，以评估中高强度体力活动、娱乐性屏幕时间、睡眠时间和其他协变量。使用生物电阻抗分析测量体脂百分比。我们发现，亚洲青少年在遵守 24 小时运动指南方面存在差异。调整协变量后，遵守运动指南的数量与亚洲青少年的体脂百分比呈负相关。此外，与未遵守任何指南相比，只遵守睡眠指南以及同时遵守体力活动和睡眠指南与体脂百分比呈负相关。本研究结果增进了我们对遵守 24 小时运动指南如何有益于青少年健康体重的理解，也为制定亚洲青少年 24 小时运动指南提供了依据。未来需要进一步研究，以深入了解遵守 24 小时运动指南与肥胖之间的关联方向，以及亚洲青少年中这些关联的潜在机制。
