The purpose of this study was to investigate the association between depressive symptoms and physical inactivity, and whether motives for and barriers to exercise explain the potential association between depressive symptoms and physical inactivity in older people. The design of the study was cross-sectional. The study population comprised 645 people born between 1922 and 1928 who were residents in a city-center area of Jyväskylä in central Finland. Depressive symptoms were assessed using Center for the Epidemiologic Studies Depression Scale, physical activity using Grimby's (1986) validated scale, and motives for and barriers to exercise using a questionnaire and mobility limitation with a test of walking time over 10 m. The results demonstrated that the risk of physical inactivity was more than twofold among persons with depressive symptoms compared with non-depressed people. A higher prevalence of perceived barriers to physical activity, such as poor health, fear and negative experiences, together with lack of knowledge, explained part of the increased risk of physical inactivity among those with depressive symptoms while differences in motives for physical activity did not have a material effect. Adjustment for walking time over 10 m attenuated the increased risk of inactivity further. When planning exercise promotion programs, finding ways to overcome fear and negative experiences and providing information may help to increase physical activity among people with depressive symptoms. Additionally, difficulties caused by poor mobility should not be ignored.
本研究旨在探讨抑郁症状与身体活动不足之间的关联，以及运动动机和障碍是否可以解释抑郁症状与老年人身体活动不足之间的潜在关联。本研究采用横断面设计。研究对象为居住在芬兰中 央约恩苏市市中心的 645 名 1922 年至 1928 年出生的人群。使用中心流行病学研究抑郁量表评估抑郁症状，使用格里姆比（Grimby）（1986 年）验证的量表评估身体活动，使用问卷评估运动动机和障碍，并通过行走 10 米的时间测试评估行动能力受限。结果表明，与非抑郁人群相比，有抑郁症状的人身体活动不足的风险高出两倍以上。感知到的身体活动障碍（如健康状况不佳、恐惧和负面经历）以及缺乏知识的发生率较高，这部分解释了抑郁症状人群身体活动不足风险增加的原因，而运动动机的差异则没有产生实质性的影响。对行走 10 米以上时间的调整进一步减弱了身体活动不足的风险。在规划运动促进计划时，寻找克服恐惧和负面经验以及提供信息的方法可能有助于增加有抑郁症状人群的身体活动量。此外，还不应忽视因行动能力受限而导致的困难。
