The interpretation of previous studies on the association of physical activity and sedentary behaviour with psychological health is limited by the use of mostly self-reported physical activity and sedentary behaviour, and a focus on Western populations. We aimed to explore the association of self-reported and devise-based measures of physical activity and sedentary behaviour domains on psychological distress in an urban multi-ethnic Asian population.
From a population-based cross-sectional study of adults aged 18-79 years, data were used from an overall sample (n = 2653) with complete self-reported total physical activity/sedentary behaviour and domain-specific physical activity data, and a subsample (n = 703) with self-reported domain-specific sedentary behaviour and accelerometry data. Physical activity and sedentary behaviour data were collected using the Global Physical Activity Questionnaire (GPAQ), a domain-specific sedentary behaviour questionnaire and accelerometers. The Kessler Screening Scale (K6) and General Health Questionnaire (GHQ-12) were used to assess psychological distress. Logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals, adjusted for socio-demographic and lifestyle characteristics.
The sample comprised 45.0% men (median age = 45.0 years). The prevalence of psychological distress based on the K6 and GHQ-12 was 8.4% and 21.7%, respectively. In the adjusted model, higher levels of self-reported moderate-to-vigorous physical activity (MVPA) were associated with significantly higher odds for K6 (OR = 1.47 [1.03-2.10]; p-trend = 0.03) but not GHQ-12 (OR = 0.97 [0.77-1.23]; p-trend = 0.79), when comparing the highest with the lowest tertile. Accelerometry-assessed MVPA was not significantly associated with K6 (p-trend = 0.50) nor GHQ-12 (p-trend = 0.74). The highest tertile of leisure-time physical activity, but not work- or transport-domain activity, was associated with less psychological distress using K6 (OR = 0.65 [0.43-0.97]; p-trend = 0.02) and GHQ-12 (OR = 0.72 [0.55-0.93]; p-trend = 0.01). Self-reported sedentary behaviour was not associated with K6 (p-trend = 0.90) and GHQ-12 (p-trend = 0.33). The highest tertile of accelerometry-assessed sedentary behaviour was associated with significantly higher odds for K6 (OR = 1.93 [1.00-3.75]; p-trend = 0.04), but not GHQ-12 (OR = 1.34 [0.86-2.08]; p-trend = 0.18).
Higher levels of leisure-time physical activity and lower levels of accelerometer-based sedentary behaviour were associated with lower psychological distress. This study underscores the importance of assessing accelerometer-based and domain-specific activity in relation to mental health, instead of solely focusing on total volume of activity.
之前关于体力活动和久坐行为与心理健康之间关联的研究解释受到限制，原因是研究主要使用自我报告的体力活动和久坐行为，并且研究对象集中在西方人群。我们旨在探索自我报告和基于设备的体力活动和久坐行为领域测量指标与城市多民族亚洲人群心理困扰之间的关联。
本研究基于一项针对 18-79 岁成年人的基于人群的横断面研究，数据来自一个总体样本（n=2653），该样本包含完整的自我报告总体力活动/久坐行为和特定领域体力活动数据，以及一个亚样本（n=703），该亚样本包含自我报告特定领域久坐行为和加速度计数据。体力活动和久坐行为数据使用全球体力活动问卷（GPAQ）、特定领域久坐行为问卷和加速度计收集。使用 Kessler 筛查量表（K6）和一般健康问卷（GHQ-12）评估心理困扰。使用 logistic 回归模型计算优势比（OR）和 95%置信区间，并根据社会人口统计学和生活方式特征进行调整。
该样本包括 45.0%的男性（中位数年龄为 45.0 岁）。基于 K6 和 GHQ-12 的心理困扰患病率分别为 8.4%和 21.7%。在调整后的模型中，较高水平的自我报告中等到剧烈体力活动（MVPA）与 K6 显著更高的比值比（OR=1.47[1.03-2.10]；p 趋势=0.03）相关，但与 GHQ-12 无关（OR=0.97[0.77-1.23]；p 趋势=0.79），最高三分位与最低三分位相比。加速度计评估的 MVPA 与 K6 无显著关联（p 趋势=0.50），与 GHQ-12 也无显著关联（p 趋势=0.74）。休闲时间体力活动的最高三分位与 K6（OR=0.65[0.43-0.97]；p 趋势=0.02）和 GHQ-12（OR=0.72[0.55-0.93]；p 趋势=0.01）的心理困扰程度较低有关，但工作或交通领域的体力活动无关。自我报告的久坐行为与 K6（p 趋势=0.90）和 GHQ-12（p 趋势=0.33）无关。加速度计评估的久坐行为最高三分位与 K6 显著更高的比值比（OR=1.93[1.00-3.75]；p 趋势=0.04）相关，但与 GHQ-12 无关（OR=1.34[0.86-2.08]；p 趋势=0.18）。
较高水平的休闲时间体力活动和较低水平的基于加速度计的久坐行为与较低的心理困扰有关。本研究强调了评估基于加速度计和特定领域的活动与心理健康之间关系的重要性，而不仅仅是关注活动总量。
