Several studies have investigated the association between physical exercise and depressive symptoms in the elderly population. However, the relationship between components of physical exercise such as frequency, intensity, duration, and depressive symptoms remains unclear. This study was conducted on elderly Chinese women to investigate the association between each component of physical exercise and depressive symptoms and to examine the association between physical exercise patterns and depressive symptoms.
A total of 1429 Chinese women aged ≥60 years were enrolled in this cross-sectional study and provided information on their exercise behaviors through a self-reported questionnaire. Depressive symptoms were assessed using the Zung Self-Rating Depression Scale. Multiple logistic regression analysis was used to estimate adjusted odds ratios (ORs) to measure the association between exercise behaviors and depression.
High frequency, moderate intensity, long duration, and exercise habits were significantly associated with lower levels of depressive symptoms. Furthermore, participants with more than one optimal exercise behavior were more likely to have a lower risk of depressive symptoms. These associations were not changed after adjustment for confounding factors.
This study shows that exercise behaviors were significantly associated with the risk of developing depression. This finding suggests that keeping an optimal exercise behavior may be associated with a lower risk of depressive symptoms in elderly Chinese women.
多项研究调查了老年人群体育锻炼与抑郁症状之间的关联。然而，体育锻炼的各个组成部分（如频率、强度、持续时间）与抑郁症状之间的关系仍不明确。本研究针对中国老年女性进行，旨在调查体育锻炼各组成部分与抑郁症状之间的关联，并检验体育锻炼模式与抑郁症状之间的关联。
共有1429名年龄≥60岁的中国女性参与了这项横断面研究，她们通过一份自我报告问卷提供了自己的运动行为信息。使用zung自评抑郁量表评估抑郁症状。采用多元逻辑回归分析来估计调整后的优势比（OR），以衡量运动行为与抑郁之间的关联。
高频率、中等强度、长时间以及运动习惯与较低水平的抑郁症状显著相关。此外，具有一种以上最佳运动行为的参与者患抑郁症状的风险更低。在对混杂因素进行调整后，这些关联并未改变。
本研究表明，运动行为与患抑郁症的风险显著相关。这一发现表明，保持最佳运动行为可能与中国老年女性患抑郁症状的风险较低有关。
