Introduction

The relationship between physical activity (PA) and positive mental health (PMH) has been studied mainly by either concentrating on total PA or focusing on leisure time PA. This study investigated whether total PA and PA domains of leisure time, commuting and occupational PA and screen time sitting at home were associated with PMH.

Methods

The study used a national population study, the FinHealth 2017 Study that included the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) as a measurement for PMH. Of all (n = 10305, of whom 10247 were eligible) invited, 58.1% (5952) participated in health examination and were given a questionnaire including the WEMWBS. A total of 5337 (52.1% of the eligible sample, 89.7% of the health examination participants) returned the questionnaire. The WEMWBS scale was adequately completed by 5090 participants (55.6% women, mean age 55.5 years). Low, moderate and high level of PMH categories were formed. Leisure time, occupational and commuting PA domains were assessed separately and together as a total PA index. Also, screen time sitting at home was measured. Binary logistic regression models were utilized to estimate the odds ratios for having low PMH compared with moderate PMH and separately for having high PMH compared with moderate PMH. The models were estimated both with and without adjustment for potential confounders.

Results

Physical inactivity (total PA) was associated with lower levels of PMH. Some of the PA domains were strongly associated with low PMH; leisure time physical inactivity and long screen time sitting at home were strongly related to higher odds of low PMH. Commuting PA was associated with high PMH.

Conclusions

The study highlights the importance of PA with relation to PMH among adults. Especially, physical inactivity was strongly associated with low PMH. As low levels of PMH can potentially present a risk for mental ill-health, this study suggests it is important to increase PA among the least active population.

体育锻炼与积极的心理健康的关联：一项基于人群的研究

介绍

身体活动（PA）与积极精神健康（PMH）之间的关系主要通过集中于总PA或关注休闲时间PA来研究。这项研究调查了闲暇时间，通勤和职业PA的总PA和PA域以及在家中的放映时间是否与PMH相关。

方法

该研究使用了一项全国人口研究，即FinHealth 2017研究，其中包括沃里克-爱丁堡精神健康量表（WEMWBS）作为PMH的量度。在所有受邀者（n = 10305，其中10247名合格者）中，有58.1％（5952）参加了健康检查并获得了包括WEMWBS在内的问卷。总共5337（占合格样本的52.1％，健康检查参与者的89.7％）返回了调查表。共有5090名参与者（55.6％的女性，平均年龄55.5岁）充分完成了WEMWBS量表。形成了低，中，高水平的PMH类别。休闲时间，职业和通勤PA域分别进行评估，并一起作为总PA指数进行评估。另外，还测量了坐在家里的屏幕时间。二元逻辑回归模型用于估计与中等PMH相比PMH低的比值比，与中等PMH相比PMH高的比值比。在对潜在混杂因素进行调整和不进行调整的情况下，对模型进行了估算。

结果

缺乏运动（总PA）与较低的PMH水平相关。一些PA域与低PMH密切相关；闲暇时间身体不活动和坐在家里呆在屏幕上的时间长与低PMH发生几率高有关。通勤PA与高PMH相关。

结论

该研究强调了成年人中PA与PMH相关的重要性。尤其是，缺乏运动与PMH低密切相关。由于低水平的PMH可能会带来精神疾病的风险，因此本研究表明，在最不活跃的人群中增加PA至关重要。
