BACKGROUND
Emerging evidence suggests the adverse association between sedentary behaviour (SB) with physical and mental health, but few studies have investigated the relationship between volume of physical activity and psychological distress. The present study examined the independent and interactive associations of daily SB and weekly level of moderate to vigorous physical activity (MVPA) with psychological distress in a multi-ethnic Asian population.
METHODS
De-identified data of 4,337 adults (18-79 years old) on sedentary behaviors, physical activity patterns, psychological distresses, and other relevant variables were obtained from the Singapore Ministry of Health's 2010 National Health Survey. Psychological distress was assessed using General Health Questionnaire-12 (GHQ-12), whereas total daily SB and total weekly volume (MET/minutes) of MVPA were estimated using the Global Physical Activity Questionnaire version 2 (GPAQ v2). Multivariate logistic regression analyses were carried out to estimate the odds ratios (95% confidence intervals) of the independent and interactive relationships of SB and MVPA with prevalence of psychological distress.
RESULTS
The category of high SB was positively associated with increased odds (OR = 1.29, 1.04-1.59) for psychological distress, whereas the category of active was inversely associated with lower odds (OR = 0.73, 0.62-0.86) for psychological distress. Multivariate analyses for psychological distress by combined daily SB and weekly MVPA levels showed inverse associations between middle SB and active categories (OR = 0.58, 0.45 - 0.74) along with low SB and active categories (OR = 0.61, 0.47-0.80).
CONCLUSIONS
The present population-based cross-sectional study indicated that in the multi-ethnic Asian society of Singapore, a high level of SB was independently associated with psychological distress and meeting the recommended guidelines for physical activity along with ≤ 5 h/day of SB was associated with the lowest odds of psychological distress.
背景
新出现的证据表明久坐行为（SB）与身心健康之间存在不良关联，但很少有研究调查身体活动量与心理困扰之间的关系。本研究在一个多民族亚洲人群中，检验了每日SB和每周中度至剧烈身体活动（MVPA）水平与心理困扰之间的独立关联和交互作用。
方法
从新加坡卫生部2010年全国健康调查中获取了4337名成年人（18 - 79岁）关于久坐行为、身体活动模式、心理困扰及其他相关变量的去识别化数据。使用一般健康问卷 - 12（GHQ - 12）评估心理困扰，而使用全球身体活动问卷第2版（GPAQ v2）估计每日总SB和每周MVPA总量（代谢当量/分钟）。进行多因素逻辑回归分析，以估计SB和MVPA与心理困扰患病率的独立及交互关系的比值比（95%置信区间）。
结果
高SB类别与心理困扰的几率增加呈正相关（OR = 1.29，1.04 - 1.59），而活跃类别与心理困扰的几率降低呈负相关（OR = 0.73，0.62 - 0.86）。通过每日SB和每周MVPA水平组合对心理困扰进行的多因素分析显示，中等SB与活跃类别（OR = 0.58，0.45 - 0.74）以及低SB与活跃类别（OR = 0.61，0.47 - 0.80）之间存在负相关。
结论
本基于人群的横断面研究表明，在新加坡的多民族亚洲社会中，高水平的SB与心理困扰独立相关，达到身体活动推荐指南且每日SB≤5小时与心理困扰的几率最低相关。
