Sedentary behavior (including sitting) is negatively associated with physical health, independent from physical activity (PA). Knowledge on the associations with mental health is less elaborated. Therefore this study aims to investigate the relationship between sitting and 5 indices of mental health in adults (psychological distress, depression, anxiety, somatization, and sleeping problems), and between sitting interactions (sitting×gender, sitting×age, sitting×education, and sitting×PA) and these mental health indices.
A cohort of Belgian adults (25-64 years; n = 4344) provided self-reported data on sitting and PA and on 5 mental health indices. Cross-sectional associations were examined using multiple linear regression analyses.
Analyses adjusted for gender, age, education, and PA showed significant positive associations between sitting and the 5 mental health indices (P < .05). All associations were true for both men and women, and for low and high educated individuals, while some were only found in older individuals (somatization, P < .001) and those being insufficiently active (psychological distress, P = .007; depression, P = .002; and anxiety, P = .014).
More sitting seems to be associated with poorer mental health, independently of gender, age, education, and PA. Moderation analyses showed that these associations may differ according to age and PA levels.
久坐行为（包括坐着）与身体健康呈负相关，与身体活动（PA）无关。与心理健康的关联知识阐述得较少。因此，本研究旨在调查成年人久坐行为与 5 项心理健康指标（心理困扰、抑郁、焦虑、躯体化和睡眠问题）之间的关系，以及久坐行为与这些心理健康指标之间的交互作用（久坐×性别、久坐×年龄、久坐×教育和久坐×PA）。
本队列研究包括来自比利时的成年人（25-64 岁；n=4344），提供了关于久坐行为和 PA 以及 5 项心理健康指标的自我报告数据。使用多线性回归分析来检验横断面关联。
调整了性别、年龄、教育和 PA 后，久坐与 5 项心理健康指标之间存在显著正相关（P<.05）。所有关联在男性和女性、低教育程度和高教育程度的个体中都是真实的，而有些关联仅在年龄较大的个体（躯体化，P<.001）和活动不足的个体（心理困扰，P=.007；抑郁，P=.002；焦虑，P=.014）中发现。
久坐时间增加似乎与心理健康较差有关，与性别、年龄、教育和 PA 无关。调节分析表明，这些关联可能因年龄和 PA 水平而异。
