【摘要】 目的：通过系统评价方法综合评估儿童青少年久坐行为与焦虑症状之间的关联性，为理解久坐行为对心理健康的影响提供循证依据。方法：系统检索PubMed、Embase、Web of Science、Cochrane Library、中国知网、万方和维普数据库，自建库起至2025年8月31日。纳入所有探讨久坐行为或屏幕使用时间与焦虑症状相关性的队列研究。使用纽卡斯尔—渥太华量表对纳入研究进行偏倚风险评估，并采用定性综合方法，对久坐行为的类型、测量方式及其与焦虑症状的关系进行分析与总结。结果：共纳入6项队列研究，总样本量为18 572名儿童青少年。多项研究显示，久坐行为与焦虑症状之间呈正相关关系，但研究间存在明显的异质性，部分研究未发现显著关联。进一步分析表明，娱乐屏幕时间与焦虑症状的关联较为一致。结论：久坐行为尤其是娱乐屏幕时间的增加，可能与儿童青少年焦虑症状风险增加相关。未来研究应结合主观报告与客观测量方法，进一步区分不同类型的久坐行为，并深入探讨其影响焦虑症状的内在机制，以期为制定针对性的预防与干预策略提供科学依据。更多还原

【Abstract】 Objective: To comprehensively assess the association between sedentary behavior and anxiety symptoms in children and adolescents by means of a systematic review method, so as to provide an evidence-based understanding of the impact of sedentary behavior on mental health. Methods: A comprehensive literature search was conducted in PubMed, Embase, Web of Science, Cochrane Library, CNKI, WanFang, and VIP databases from inception to August 31, 2025. Cohort studies investigating the relationship between sedentary behavior or screen time and anxiety symptoms were included. The Newcastle-Ottawa scale was used to assess the risk of bias in the included studies. A qualitative synthesis was performed to analyze the types of sedentary behavior, measurement methods, and their associations with anxiety symptoms. Results: Six cohort studies involving a total of 18,572 children and adolescents were included. Most studies indicated a positive association between sedentary behavior and anxiety symptoms, although significant heterogeneity was observed across studies, with some reporting non-significant associations. Further analysis suggested that recreational screen time was more consistently associated with anxiety symptoms. Conclusion: Current evidence suggests that increased sedentary behavior, particularly recreational screen use, may be associated with an elevated risk of anxiety symptoms in children and adolescents. Future research should employ mixed-method approaches combining subjective and objective measures to better differentiate types of sedentary behavior and elucidate the underlying mechanisms linking sedentary behavior to anxiety, so as to provide a scientific basis for formulating targeted preventive and intervention strategies.更多还原
