虽然一些证据表明，运动可以改善心理健康状况，但有关运动强度和持续时间的信息并不完整。本研究的目的是阐明休闲时间和通勤时间的身体活动与心理健康之间的关系。在日本的三个市政厅进行了问卷调查。共有670名男性和女性完成了调查问卷。心理健康状况评估由28项一般健康问卷（GHQ）。受访者被问及每周四个运动水平的闲暇时间运动时间，并使用代谢当量任务指数评估运动量。还获得了关于步行或骑自行车上下班的信息。根据体力活动水平，采用协方差分析计算平均GHQ评分，并调整包括工作压力在内的潜在混杂因素。在男性中，GHQ评分随着休闲时间锻炼水平的增加而稳步下降，即使是轻度强度的锻炼也明显呈负相关。此外，GHQ评分下降，根据增加的时间上下班的步行或骑自行车的男性，但不是在女性。调整潜在混杂因素后，这些关系没有实质性变化。在女性中，任何身体活动指数之间都没有显着关联。总之，休闲时间锻炼和步行或骑自行车上下班可能与男性更好的心理健康有关。
Although some evidence suggests that exercise may improve mental health status, information regarding the intensity and duration of exercise is incomplete. The purpose of this study was to elucidate the association between physical activities in both leisure time and commuting to work and mental health. A questionnaire survey was conducted at three municipal offices in Japan. A total of 670 men and women completed the questionnaire. Mental health status was assessed by the 28-item General Health Questionnaire (GHQ). Respondents were asked about weekly hours of leisure-time exercise for four levels of exercise, and the volume of exercise was assessed using a metabolic equivalent task index. Information about commuting to work on foot or by bicycle was also obtained. The mean GHQ scores were calculated according to physical activity levels using analysis of covariance with adjustment of potential confounders including job stress. In men, the GHQ score decreased steadily with increasing levels of leisure-time exercise, and an inverse association was evident even for mild intensity exercise. Moreover, the GHQ score decreased according to increasing duration of time on commuting to work by either walking or cycling in men, but not in women. These relations did not materially change after adjustment for potential confounding factors. In women, there was no significant association between any of the indices of physical activity. In conclusion, leisure-time exercise and walking or cycling during commuting to work may be associated with better mental health in men.
