Data_Sheet_1_Association between meeting 24-h movement guidelines and health in children and adolescents aged 5–17 years: a systematic review and meta-analysis.docx

Twenty-four-hour movement behaviors have significant implications for physical and mental health throughout one’s lifespan. Consistent with movement behaviors, several countries have formulated and published 24-h movement guidelines. This review summarized the studies related to 24-h movement guidelines among children and adolescents from six databases (MEDLINE, EMBASE, PubMed, Web of Science, CINAHL, and SPORTDiscus). In a total of 61 studies that discussed compliance with 24-h movement guidelines, the overall adherence rate was very low (7.6%), with boys exceeding girls, children surpassing adolescents, and regional differences. A total of 39 studies examined the associations between 24-h movement guidelines and health indicators. Findings indicated that meeting all three guidelines was favorably associated with adiposity, cardiometabolic health, mental and social health, physical fitness, health-related quality of life, academic achievement, cognitive development, perceived health, dietary patterns, and myopia. Future research should utilize longitudinal and experimental designs to enhance our understanding of the associations between 24-h movement guidelines and health indicators, thereby aiding the formulation and refinement of such guidelines.

24小时身体活动行为（24-hour movement behaviors）对个体整个生命周期的身心健康均具有重要意义。针对此类活动行为，已有多个国家制定并发布了24小时运动指南（24-hour movement guidelines）。本系统综述检索了MEDLINE、EMBASE、PubMed、Web of Science、CINAHL及SPORTDiscus共6个数据库中与儿童青少年24小时运动指南相关的研究。在共计61项探讨24小时运动指南依从性的研究中，整体依从率极低，仅为7.6%，且依从情况呈现男孩高于女孩、儿童高于青少年以及存在地域差异的特征。另有39项研究分析了24小时运动指南与各类健康指标间的关联。研究结果显示，同时满足全部三项指南要求与体脂状况、心血管代谢健康、心理与社会健康、身体素质、健康相关生活质量、学业成就、认知发育、自我感知健康、饮食模式及近视均存在显著正向关联。未来研究可采用纵向设计与实验设计，以加深对24小时运动指南与健康指标间关联的理解，进而助力此类指南的制定与优化。本系统综述注册号：https://www.crd.york.ac.uk/prospero/，CRD42023481230。
