As the aging population grows, identifying effective interventions to achieve healthy ageing is crucial. Specific environments, such as Curves, the women-only fitness club (WOFC), may provide a supportive setting for older women to engage in physical activities that promote overall healthy ageing. This study aims to compare the functional disability prediction score between WOFC members and control group in older adults.
Our study design was cross-sectional design. We applied propensity score matching to control for 9 potential confounders, including age, sociodemographic factors, health-related factors. A total of 6,058 participants were matched (3,029 WOFC memberships and 3,029 control groups from the Japan Gerontological Evaluation Study). The functional disability prediction scores we used can predict the risk of functional disability within three years for community-dwelling older adults without activity of daily living limitations.
After propensity score matching, the covariates of the two groups were well balanced. The average age after propensity score matching was 72.4 for WOFC members and 72.7 for the control group. The average functional disability prediction score was 0.53 points lower for WOFC members than for the control group (p =.005).
WOFC members had lower scores on the functional disability prediction score related to healthy aging. Future studies should investigate the long-term impact of such programs.
随着老年人口的增长，确定实现健康老龄化的有效干预措施至关重要。特定环境，如女子健身俱乐部Curves，可能为老年女性提供一个支持性环境，使其参与促进整体健康老龄化的体育活动。本研究旨在比较老年女性健身俱乐部成员与对照组在功能残疾预测评分上的差异。
我们的研究设计为横断面设计。我们应用倾向得分匹配法来控制9个潜在混杂因素，包括年龄、社会人口学因素、健康相关因素。总共6058名参与者进行了匹配（3029名女子健身俱乐部会员和来自日本老年学评估研究的3029名对照组）。我们使用的功能残疾预测评分可以预测无日常生活活动受限的社区居住老年人在三年内出现功能残疾的风险。
经过倾向得分匹配后，两组的协变量平衡良好。倾向得分匹配后的平均年龄，女子健身俱乐部成员为72.4岁，对照组为72.7岁。女子健身俱乐部成员的平均功能残疾预测评分比对照组低0.53分（p = 0.005）。
女子健身俱乐部成员在与健康老龄化相关的功能残疾预测评分上得分较低。未来的研究应调查此类项目的长期影响。
