Physical activity (PA) provides substantial mental and physical health benefits for individuals of all ages. A limited number of long-term or longitudinal studies have investigated the association between psychosocial factors and PA in healthy older adults aged 65 and above. This study aimed to determine the long-term relationship between psychosocial factors, such as vitality, mental health, anxiety, and depression, and objectively measure PA in older adults.
Healthy participants from Nakanojo, Japan, aged 65-90, capable of walking, were included in this study and were followed up from 2008 to 2013. Those diagnosed with dementia and depression were excluded. Using a repeated cross-sectional dataset, a multilevel model was developed with psychosocial variables as independent variables and an average daily duration of PA volume of > 3 metabolic equivalents (METs) as the outcome. The Akaike information criterion was used to select the final model.
This study included 1108 records from 319 participants. In the multilevel model, age (coefficient = -0.106, 95% confidence interval [CI] = -0.127 to -0.086, p < 0.001) and the Hospital Anxiety and Depression Scale depression scores (coefficient = -0.019, 95% CI = -0.036 to -0.002, p = 0.026) were negatively associated with the duration of PA volume > 3 METs, whereas male sex (coefficient = 0.343, 95% CI = 0.115 to 0.571, p = 0.003) was positively associated with PA volume.
Depressive symptoms were related to a reduced duration of PA volume of > 3 METs among these adults aged 65 and above.
体育活动（PA）对各年龄段的人都有显著的身心健康益处。仅有少数长期或纵向研究调查了65岁及以上健康老年人心理社会因素与体育活动之间的关联。本研究旨在确定心理社会因素（如活力、心理健康、焦虑和抑郁）与老年人体育活动之间的长期关系，并客观测量老年人的体育活动情况。
本研究纳入了来自日本中之条市、年龄在65 - 90岁、能够行走的健康参与者，并于2008年至2013年对其进行随访。排除了被诊断患有痴呆症和抑郁症的参与者。利用重复横断面数据集，构建了一个以心理社会变量为自变量、以平均每日体育活动量大于3代谢当量（METs）的持续时间为结果的多层次模型。采用赤池信息准则来选择最终模型。
本研究纳入了319名参与者的1108条记录。在多层次模型中，年龄（系数 = -0.106，95%置信区间[CI] = -0.127至-0.086，p < 0.001）和医院焦虑抑郁量表抑郁评分（系数 = -0.019，95% CI = -0.036至-0.002，p = 0.026）与体育活动量大于3 METs的持续时间呈负相关，而男性（系数 = 0.343，95% CI = 0.115至0.571，p = 0.003）与体育活动量呈正相关。
在这些65岁及以上的成年人中，抑郁症状与体育活动量大于3 METs的持续时间缩短有关。
