OBJECTIVE
The study aimed to analyze the independent and joint associations of physical activity (PA) and sedentary behavior (SB) with self-rated health (SRH) among Chinese children and adolescents.
METHODS
Cross-sectional data on moderate-to-vigorous physical activity (MVPA), school-based PA, extracurricular physical activity (EPA), screen time (ST), homework time, and SRH were assessed through a self-report questionnaire in the sample of 4227 Chinese children and adolescents aged 13.04 ± 2.62 years. Binary logistic regression was used to compare gender differences in PA, SB, and SRH among children and adolescents, and analyses were adjusted for age and ethnicity.
RESULTS
In independent associations, boys and girls engaging in ≥60 min/day of MVPA and >1 hour/day of EPA reported optimal SRH. Only boys who participated in >1 hour/day of school-based PA were significantly more likely to have optimal SRH (OR = 1.49, 95%CI = 1.19-1.86). Only girls who had ≤2 hours/day of ST were significantly associated with optimal SRH (weekdays: OR = 1.38, 95%CI = 1.10-1.74; weekends: OR = 1.40, 95%CI = 1.14-1.71; whole week: OR = 1.42, 95%CI = 1.16-1.73). In joint associations, regardless of SB recommendation, meeting PA recommendation was significantly associated with optimal SRH in both boys (meet PA and SB recommendations, OR = 1.61, 95%CI = 1.03-2.50; meet PA but not SB recommendations, OR = 2.40, 95%CI = 1.57-3.65) and girls (meet PA and SB recommendations, OR = 3.72, 95%CI = 2.08-6.65; meet PA but not SB recommendation, OR = 4.27, 95%CI = 2.09-8.75).
CONCLUSION
Increased PA and reduced SB were positively associated with optimal SRH in Chinese children and adolescents. Notably, lower ST positively influenced only girls' SRH. Meeting PA recommendation is more impactful than meeting SB recommendation for improving SRH in Chinese children and adolescents. Future studies could explore these associations using objective measures of PA and SB in China.
目的
本研究旨在分析中国儿童和青少年身体活动（PA）和久坐行为（SB）与自感健康（SRH）的独立和联合关联。
方法
通过问卷调查，对 4227 名年龄在 13.04±2.62 岁的中国儿童和青少年进行了中等到剧烈强度的体力活动（MVPA）、校内 PA、课外 PA、屏幕时间（ST）、家庭作业时间和 SRH 的评估。采用二元逻辑回归比较儿童和青少年 PA、SB 和 SRH 的性别差异，分析结果调整了年龄和种族因素。
结果
在独立关联中，每天进行≥60 分钟 MVPA 和>1 小时 EPA 的男孩和女孩报告了最佳的 SRH。只有每天参加>1 小时校内 PA 的男孩，其 SRH 更有可能达到最佳状态（OR=1.49，95%CI=1.19-1.86）。只有每天 ST 时间≤2 小时的女孩与最佳 SRH 显著相关（工作日：OR=1.38，95%CI=1.10-1.74；周末：OR=1.40，95%CI=1.14-1.71；整周：OR=1.42，95%CI=1.16-1.73）。在联合关联中，无论 SB 建议如何，PA 建议的符合与男孩（符合 PA 和 SB 建议，OR=1.61，95%CI=1.03-2.50；符合 PA 但不符合 SB 建议，OR=2.40，95%CI=1.57-3.65）和女孩（符合 PA 和 SB 建议，OR=3.72，95%CI=2.08-6.65；符合 PA 但不符合 SB 建议，OR=4.27，95%CI=2.09-8.75）的最佳 SRH 显著相关。
结论
增加 PA 和减少 SB 与中国儿童和青少年的最佳 SRH 呈正相关。值得注意的是，较低的 ST 仅对女孩的 SRH 产生积极影响。与符合 SB 建议相比，符合 PA 建议对改善中国儿童和青少年的 SRH 更具影响力。未来的研究可以使用中国的 PA 和 SB 的客观测量来探索这些关联。
