The dose-response association between physical activity (PA) and mental health is poorly described. We explored cross-sectional associations between physical activity and common mental disorder (psychological distress) in 'weekend warriors' who do all their exercise in one or two sessions per week.
Adult participants (n = 108,011, age = 47 ± 17 yrs., 46.5% men) were recruited from general population household-based surveys (Health Survey for England and Scottish Health Survey) from 1994 to 2004. Data were pooled and analyzed using logistic regression models. Moderate to vigorous physical activity (MVPA) was self-reported and psychological distress was measured using the 12 item General Health Questionnaire (GHQ-12).
Psychological distress (GHQ-12 > 3) was prevalent in 14.5% of the sample. In healthy participants an inverse association between PA and psychological distress was optimal at the PA guideline (150 mins/wk. MVPA or 75 min/wk. Vigorous PA) regardless of whether it was accumulated in one or two bouts per week "Weekend warrior" (odd ratio = 0.68, 95% CI, 0.63, 0.73) or as more frequent daily bouts (odd ratio = 0.68, 95% CI, 0.64, 0.72) in comparison to the inactive reference group. In participants with chronic health conditions an inverse association between PA and psychological distress was also evident at lower doses (one or two sessions of PA a week below PA guideline) (OR = 0.72, 95% CI, 0.68, 0.77). Undertaking vigorous intensity PA as part of the PA guideline conferred additional benefit in women (odds ratio = 0.87, 95% CI, 0.75, 1.00), but not men.
Mental health benefits may be accrued through different PA patterns, thus individual approaches to prescribing exercise should be promoted.
体力活动（PA）与心理健康之间的剂量反应关联描述甚少。我们探讨了“周末战士”（每周进行一或两次锻炼）的体力活动与常见精神障碍（心理困扰）之间的横断面关联。
从1994年至2004年的一般人群家庭调查（英格兰健康调查和苏格兰健康调查）中招募成年参与者（n = 108,011，年龄 = 47±17岁，男性占46.5%）。汇总数据并使用逻辑回归模型进行分析。中度至剧烈体力活动（MVPA）通过自我报告获得，心理困扰使用12项一般健康问卷（GHQ - 12）进行测量。
样本中14.5%的人存在心理困扰（GHQ - 12 > 3）。在健康参与者中，无论PA是每周累积在一或两次“周末战士”锻炼中（比值比 = 0.68，9�%置信区间，0.63，0.73），还是更频繁地分散在日常锻炼中（比值比 = 0.68，9�%置信区间，0.64，0.72），与不活动的参照组相比，PA与心理困扰之间的负相关在PA指南（每周150分钟MVPA或每周75分钟剧烈PA）时最为明显。在患有慢性健康状况的参与者中，PA与心理困扰之间的负相关在较低剂量（每周低于PA指南的一或两次PA锻炼）时也很明显（比值比 = 0.72，9�%置信区间，0.68，0.77）。作为PA指南的一部分进行剧烈强度的PA对女性有额外益处（比值比 = 0.87，9�%置信区间，0.75，1.00），但对男性没有。
通过不同的PA模式可能获得心理健康益处，因此应推广个性化的运动处方方法。
