This study investigated the association between sedentary behavior (SB) and anxiety, and explored factors that influence this relationship in six low- and middle-income countries.
Cross-sectional data were analyzed from the World Health Organization's Study on Global Ageing and Adult Health. Multivariable linear and logistic regression analyses were conducted to assess the association between anxiety and self-reported SB. Potentially influential factors were examined with mediation analysis.
The sample consisted of 42,469 adults aged≥18years (50.1% female; mean age 43.8years). After adjusting for sociodemographics and country, people with anxiety engaged in 24 (95%CI=7-41) more minutes per day of SB than non-anxious individuals; the corresponding figure for the elderly (≥65years) was much higher (55min; 95% CI=29-81). Anxiety was associated with a 2.0 (95%CI=1.5-2.7) times higher odds for high SB (i.e., ≥8h/day). Overall, the largest proportion of the high SB-anxiety relationship was explained by mobility limitations (46.8%), followed by impairments in sleep/energy (44.9%), pain/discomfort (31.7%), disability (27.0%), cognition (13.3%), and physical activity levels (6.3%).
Anxiety was significantly associated with high SB, particularly among older adults. Future longitudinal studies are warranted to disentangle the potentially complex interplay of factors that may influence the anxiety-SB relationship.
本研究旨在探讨久坐行为（SB）与焦虑之间的关系，并探索六个中低收入国家中影响这种关系的因素。
使用世界卫生组织全球老龄化和成人健康研究的横断面数据进行分析。采用多变量线性和逻辑回归分析评估焦虑与自我报告的 SB 之间的关系。采用中介分析检验潜在的影响因素。
样本包括 42469 名年龄≥18 岁的成年人（50.1%为女性；平均年龄 43.8 岁）。在调整社会人口统计学和国家因素后，焦虑人群每天的 SB 时间比非焦虑人群多 24 分钟（95%CI=7-41）；老年人（≥65 岁）的这一数字要高得多（55 分钟；95%CI=29-81）。焦虑与高 SB（即≥8 小时/天）的发生几率增加 2.0 倍（95%CI=1.5-2.7）相关。总体而言，SB 与焦虑之间的高相关性主要归因于行动不便（46.8%），其次是睡眠/精力受损（44.9%）、疼痛/不适（31.7%）、残疾（27.0%）、认知能力（13.3%）和身体活动水平（6.3%）。
焦虑与高 SB 显著相关，尤其是在老年人中。未来需要进行纵向研究，以厘清可能影响焦虑与 SB 关系的复杂因素之间的潜在相互作用。
