预防抑郁症状是促进老年人健康生活方式的一个重要问题。迄今为止，很少有研究探讨老年人身体活动波动与抑郁症之间的关系。因此，我们进行了一项纵向调查的老年人，以研究长期波动的身体活动对抑郁症状的发病率的影响。MethodsA 3年的前瞻性队列研究进行了以社区为基础的环境。共有680名年龄在65岁及以上的人（291名男性和389名女性）参加了基线评估。15项老年抑郁量表用于评估抑郁症状，评分为6分表示抑郁。根据2002年至2003年间身体活动状态的变化，将参与者分为以下四组：久坐、停止、开始和维持。结果3年随访（2006年）时，抑郁症状的发生率为16.9%（男性为16.8%，女性为17.0%）。多元Logistic回归分析表明，体力活动的维护（比值比，0.50; 95%置信区间，0.30-0.83）只减少了抑郁症状的发生率在3年的后续调整后的混杂variables.ConclusionsContinuous体力活动可能是一个有价值的和简单的方法，以防止抑郁症状在社区居住的老年人。因此，有必要实施干预措施，教导老年人如何将身体活动融入日常生活。
AimsPrevention of depressive symptoms is an essential issue with regard to the promotion of healthy lifestyles in older people. To date, few studies have examined the relation between fluctuations in physical activity and depression among older individuals. We thus conducted a longitudinal survey of older adults to examine the effect of long-term fluctuating physical activity on the incidence of depressive symptoms.MethodsA 3-year prospective cohort study was performed in a community-based environment. A total of 680 individuals (291 men and 389 women) aged 65 years and over at the baseline assessment participated. The 15-item Geriatric Depression Scale was used to assess depressive symptoms, with scores of 6 indicative of depression. Participants were categorized into the following four groups based on change in physical activity status between 2002 and 2003: sedentary, cessation, initiation, and maintenance.ResultsThe incidence of depressive symptoms was 16.9% (16.8% in men and 17.0% in women) at the 3-year follow up (in 2006). Multiple logistic regression analyses showed that physical activity maintenance (odds ratio, 0.50; 95% confidence interval, 0.30-0.83) only reduced the incidence of depressive symptoms at the 3-year follow up after adjusting for confounding variables.ConclusionsContinuous physical activity may be a valuable and simple way to prevent depressive symptoms in community-dwelling older people. Therefore, it is necessary to implement interventions that teach older adults how to integrate physical activity into their daily lives.
