There is increasing interest in the association between psychological distress and time spent in sedentary behaviour (e.g. sitting), a highly prevalent behaviour in modern society. The limited evidence is mixed and mainly based on studies using self-reported sedentary time. Few studies have investigated device-based total sedentary time in its association with distress. None, however, have examined device-based domain-specific sedentary time in relation to psychological distress. The aim of this study was to investigate whether device-based total and domain-specific sedentary behaviour were associated with psychological distress.
Flemish employees (n = 401; 20-64 years; 42.6% male; 83.6% had a 'physically active occupation') of seven organizations in service and production sectors participated. Sedentary behaviour (exposure) was assessed by two Axivity AX3 accelerometers (one placed on the thigh and one placed between the shoulders) for two to four consecutive working days. Based on diary completion, domain-specific sedentary behaviour (leisure vs. work) was assessed. The 12-item General Health Questionnaire was used to assess psychological distress (outcome). Adjusted hierarchical multiple regression models were conducted to report on the associations between total and domain-specific sedentary behaviour and psychological distress.
About 35% of the sample had high levels of distress and average total sedentary time was 7.2 h/day. Device-based total sedentary behaviour [B = -0.009, 95% confidence interval (CI), -0.087 to 0.068], leisure-time (B = 0.001, 95% CI, -0.017 to 0.018) and work-related (B = 0.004, 95% CI, -0.006 to 0.015) sedentary behaviour were not significantly associated with psychological distress.
This cross-sectional study examining the association between device-based total and domain-specific sedentary behaviour and psychological distress among employees showed a lack of significant findings.
人们对心理困扰与久坐行为（例如坐着）之间的关系越来越感兴趣，久坐行为是现代社会中非常普遍的行为。现有证据有限且混杂，主要基于使用自我报告久坐时间的研究。很少有研究调查基于设备的总久坐时间与困扰之间的关系。然而，尚无研究调查基于设备的特定领域久坐时间与心理困扰的关系。本研究旨在探讨基于设备的总久坐时间和特定领域久坐时间是否与心理困扰相关。
来自服务和生产部门的七个组织的 401 名 Flemish 员工（年龄 20-64 岁，42.6%为男性，83.6%从事“体力活动职业”）参与了这项研究。通过两个 Axivity AX3 加速度计（一个放置在大腿上，一个放置在两肩之间）在两个连续工作日至四个工作日期间评估久坐行为（暴露）。基于日记完成情况，评估特定领域的久坐行为（休闲与工作）。使用 12 项一般健康问卷评估心理困扰（结果）。采用分层逐步回归模型报告总久坐时间和特定领域久坐时间与心理困扰之间的关联。
约 35%的样本存在较高水平的困扰，平均总久坐时间为 7.2 小时/天。基于设备的总久坐时间[B = -0.009，95%置信区间（CI），-0.087 至 0.068]、休闲时间（B = 0.001，95%CI，-0.017 至 0.018）和工作相关的（B = 0.004，95%CI，-0.006 至 0.015）久坐行为与心理困扰无显著关联。
这项横断面研究调查了员工中基于设备的总久坐时间和特定领域久坐时间与心理困扰之间的关系，结果显示无显著发现。
