Abstract

Abstract

Objective To investigate the impact of exercise frequency on the maintenance of elderly individuals' self-care ability. Methods A cohort study was conducted in Nanyuan Community, Liwan District, Guangzhou, from 2012 to 2020. A total of 6 905 elderly individuals were enrolled in the baseline survey and followed up for the evaluation of their self-care ability. Among the 5 154 participants included in the analysis, a marginal structural Cox proportional hazards regression model was employed to assess the relationship between daily exercise frequency and the maintenance of self-care ability among the elderly. Results Over the past year, 48.58% of study subjects exercised daily. At the last follow-up, 4.2% of the elderly were unable to take care of themselves completely, and the median follow-up time was 3.63 years. After adjusting for confounding factors, compared to no exercise, occasional exercise and daily exercise reduced the risk of not maintaining self-care ability by 44.9% (HR=0.551, 95% CI: 0.432-0.701) and 39.9% (HR=0.601, 95% CI: 0.460-0.784), respectively. The stratified analysis found that neither occasional nor daily exercise was effective in reducing the risk of smokers not being able to sustain their independence. However, for non-smokers, occasional and daily exercise reduced the risk by 45.8% (HR=0.542, 95% CI: 0.419-0.702) and 39.7% (HR=0.603, 95% CI: 0.453-0.804), respectively. For alcohol consumers, neither occasional exercise nor consistent daily exercise can effectively reduce the risk of losing the ability to maintain self-care. However, the risks of not maintaining self-care ability were more significantly reduced by occasional and daily exercise among non-drinkers, with reductions of 45.1%(HR=0.549, 95% CI: 0.429-0.704) and 39.4% (HR=0.606, 95% CI: 0.459-0.800), respectively. Conclusions Exercise can help elderly individuals maintain their self-care ability. Alcohol consumption among the elderly can attenuate the positive effects of physical exercise on maintaining self-care ability. It is recommended that elderly individuals reduce or abstain from alcohol consumption and adopt scientific exercise methods.
