In the context of an aging population, older adults increasingly face the challenge of managing multiple chronic conditions simultaneously. This study utilized analytical methods such as propensity score matching (PSM) and multivariate logistic regression, to explore the relationship between physical activity and the number of chronic diseases as well as the risk of developing co-morbidities among middle-aged and elderly Chinese individuals using data from the 2020 China Health and Retirement Longitudinal Survey. The PSM results showed that physical activity decreased the number of chronic diseases in middle-aged and elderly people by 0.050 (p < 0.05). The multivariate logistic regression results the odds ratio (OR) for the risk of multimorbidity in the moderate and high intensity physical activity groups compared to the group with inadequate physical activity were 0.845 (95% CI 0.729-0.980) and 0.847 (95% CI 0.727-0.988), which means that moderate-intensity physical activity is strongly associated with a reduced risk of multimorbidity. Regular physical activity among middle-aged and older adults is associated with a reduction in the number of chronic diseases they suffer from.
在人口老龄化的背景下，老年人越来越多地面临同时管理多种慢性病的挑战。本研究利用倾向得分匹配（PSM）和多变量逻辑回归等分析方法，使用2020年中国健康与养老追踪调查的数据，探讨中国中老年人的身体活动与慢性病数量以及患合并症风险之间的关系。PSM结果显示，身体活动使中老年人的慢性病数量减少了0.050（p<0.05）。多变量逻辑回归结果显示，与身体活动不足的组相比，中等强度和高强度身体活动组患多种疾病风险的优势比（OR）分别为0.845（95%CI 0.729-0.980）和0.847（95%CI 0.727-0.988），这意味着中等强度的身体活动与降低患多种疾病的风险密切相关。中老年成年人经常进行身体活动与他们所患慢性病数量的减少有关。
