Although the number of studies examining the relationships between sedentary behaviors (SB) and anxiety is growing, an overarching evidence, taking into account children, adolescents, and adults as well as different types of SB and different categories of anxiety outcomes, is still missing. Thus, this systematic review and meta-analysis aimed at obtaining a comprehensive overview of existing evidence.
A search in the following databases: PsycINFO, PsycARTICLES, Academic Search Complete, ERIC, HealthSource: Nursing/Academic Edition and MEDLINE, resulted in k = 31 original studies included in the systematic review (total N = 99,192) and k = 17 (total N = 27,443) included in the meta-analysis. Main inclusion criteria referred to testing the SB--anxiety relationship, the quality score (above the threshold of 65%), and the language of publications (English). The study was following the PRISMA statement and was registered at PROSPERO (CRD42017068517).
Both the systematic review and meta-analysis indicated that overall average effects were small: higher levels of symptoms of anxiety were associated with higher levels of SB (weighted r = .093, 95% CI [.055, .130], p < .001). Moderator analyses indicated that trends for stronger effects were observed among adults, compared to children/adolescents (p = .085).
Further longitudinal studies are necessary to elucidate the predictive direction of the anxiety-SB relationship and to clarify whether the effects depend on the type of anxiety indicators.
尽管研究久坐行为（SB）与焦虑之间关系的数量在不断增加，但仍缺乏一项综合考虑儿童、青少年和成年人以及不同类型 SB 和不同焦虑结果类别的全面证据。因此，本系统评价和荟萃分析旨在获得现有证据的全面概述。
在以下数据库中进行搜索：PsycINFO、PsycARTICLES、Academic Search Complete、ERIC、HealthSource：Nursing/Academic Edition 和 MEDLINE，共纳入 k=31 项原始研究进行系统评价（总 N=99192）和 k=17 项纳入荟萃分析（总 N=27443）。主要纳入标准是测试 SB-焦虑关系、质量评分（高于 65%的阈值）和出版物的语言（英语）。本研究遵循 PRISMA 声明，并在 PROSPERO（CRD42017068517）上进行了注册。
系统评价和荟萃分析均表明，总体平均效应较小：焦虑症状水平较高与 SB 水平较高相关（加权 r=0.093，95%CI [0.055，0.130]，p<0.001）。调节分析表明，与儿童/青少年相比，成年人的效应趋势更强（p=0.085）。
需要进一步进行纵向研究，以阐明焦虑-SB 关系的预测方向，并阐明效应是否取决于焦虑指标的类型。
