摘 要：基于最佳时区分析法探究青少年24 h活动最佳推荐量，验证满足该推荐量对于青少年生理、心理和社会适应健康的影响。于天津、武汉、郑州三地随机招募12~17岁儿童青少年837名(男403，女434)，采用三维加速度计测量24 h活动，包括中高强度身体活动(MVPA)、低强度身体活动(LPA)、久坐行为(SB)、睡眠(SLP)；采用自测健康评定量表评估青少年生理、心理及社会健康水平。通过构建回归模型、组建24 h活动组合、预测结局变量等步骤明确24 h活动最佳时长与区间，采用线性回归模型对24 h活动达标与结局指标之间的关系进行分析。结果显示：青少年24 h活动行为与生理健康(P＜0.001)、心理健康(P＜0.001)、社会健康(P＜0.001)呈显著正相关，在此基础上提出青少年24 h活动的最佳时长与区间为MVPA65 min(40~70 min)、LPA320 min (220~370 min)、SB440 min(240~600 min)、SLP632 min(590~680 min)。研究认为：基于生理健康、心理健康及社会健康3个维度提出我国青少年24 h活动推荐量具有重要意义。与国际相关指南相比，MVPA推荐量基本一致而SLP推荐量偏高，同时填补LPA和SB的具体推荐量。满足该方法的推荐量与较高的生理、心理及社会健康有关，为我国青少年24 h活动指南的制定及健康合理生活方式的形成提供重要参考依据。

Abstract: Examining the optimal 24-hour activity recommendations for adolescents based on optimal time zone analysis and validating their impact on physiological, psychological, and social adaptation health. A total of 837 adolescents aged 12~17 (403 males, 434 females) were randomly recruited from Tianjin, Wuhan, and Zhengzhou. Triaxial accelerometers were also used to measure 24-hour activities, including moderate-to-vigorous physical activity (MVPA), light-intensity physical activity (LPA), sedentary behavior (SB), and sleep (SLP). The self-rated health assessment scale was employed to evaluate teenagers’ physiological, psychological, and social health levels. Regression models were constructed to analyze 24-hour activity combinations, to predict outcome variables, and to identify optimal duration and ranges for 24-hour activities, and linear regression models were used to assess the relationship between meeting activity recommendations and health outcomes. The results showed that teenagers’ 24-hour activity behavior exhibited significant positive correlations with physiological health (P < 0.001), psychological health (P < 0.001), and social health (P < 0.001), and based on those, the optimal 24-hour activity duration and ranges for teenagers were determined as follows: MVPA 65 min (40~70 min), LPA 320 min (220~370 min), SB 440 min (240~600 min), and SLP 632 min (590~680 min). The study highlights the significance of establishing 24-hour activity recommendations for Chinese teenagers across physiological, psychological, and social health dimensions. Compared to international guidelines, the MVPA recommendation aligns closely, while the SLP recommendation is higher, and also provides specific guidance for LPA and SB. Meeting these recommendations correlates with enhanced physiological, psychological, and social health, offering critical insights for developing 24-hour activity guidelines and fostering healthy lifestyles among Chinese teenagers.
