Prior studies have found that exercise has a positive effect on depressive symptoms in the general population. For older individuals, however, the association between exercise and depressive symptoms is conclusive. We examined whether regular exercise is related to depressive symptoms in 5379 Korean adults aged ≥ 55 years using data from a 2016 survey administered in the Korean Longitudinal Study of Aging. We used the 10-item Center for Epidemiological Studies-Depression scale to assess depressive symptoms. We performed a multivariate logistic regression analysis to investigate the relationship between regular exercise and depressive symptoms, adjusting for sociodemographic characteristics, self-rated health, number of chronic diseases, body mass index, hand-grip strength, physical disability, cognitive impairment, and health behavior. Interaction terms, including regular exercise and health-related factors, were also added. We found that a lack of regular exercise was significantly related to an increased frequency of depressive symptoms (OR = 1.18, 95% CI = 1.03-1.35). Moreover, hand-grip strength may increase the effect of regular exercise on depressive symptoms in individuals 65 years and older (OR = 1.01 vs. 1.70, 95% CI = 1.05-1.96). Our results suggest that it is important to encourage older individuals to exercise regularly as a means of relieving depressive symptoms.
先前的研究发现，运动对普通人群的抑郁症状有积极影响。然而，对于老年人来说，运动与抑郁症状之间的关联尚无定论。我们利用韩国老年纵向研究2016年调查的数据，研究了5379名年龄≥55岁的韩国成年人中，规律运动与抑郁症状之间是否存在关联。我们使用10项流行病学研究中心抑郁量表来评估抑郁症状。我们进行了多因素逻辑回归分析，以研究规律运动与抑郁症状之间的关系，并对社会人口学特征、自评健康状况、慢性病数量、体重指数、握力、身体残疾、认知障碍和健康行为进行了调整。还加入了包括规律运动和健康相关因素在内的交互项。我们发现，缺乏规律运动与抑郁症状频率增加显著相关（比值比=1.18，95%置信区间=1.03-1.35）。此外，握力可能会增强规律运动对65岁及以上人群抑郁症状的影响（比值比=1.01对1.70，95%置信区间=1.05-1.96）。我们的研究结果表明，鼓励老年人定期锻炼作为缓解抑郁症状的一种方式很重要。
