Background This study investigates the mediating role of comfort (CMT), convenience (CNV), and aesthetics (AST) in the relationship between the enablers of an age-friendly built environment for walkability and outcomes such as increased physical activity level (IPL), increased socialization (ISL), and improved quality of life (IQL) in older adults. The research emphasizes the importance of creating age-friendly environments to support the well-being and quality of life of older adults, with implications for urban planners and policymakers to promote sustainable and inclusive design. Methods The research follows a positivist paradigm using a quantitative approach and survey strategy with a cross-sectional design. A sample of 333 older adults was selected using the convenience sampling technique, and data were gathered through a self-administered questionnaire. Results Findings from hypothesis testing indicate that, among the enablers, age-friendly urban design policies are the most significant construct, positively impacting all three mediating variables. aesthetics was found to have a significant positive effect on increased physical activity level and increased socialization, while comfort and convenience significantly influenced increased physical activity level and improved quality of life , respectively. Conclusion These results suggest implications for urban planners and policymakers to enhance the contribution of built environment for walkability toward increased physical activity level , increased socialization, and improved quality of life for older adults. The research offers valuable insights for academics and practitioners, emphasizing the importance of sustainable design while ensuring inclusivity to promote the well-being and quality of life of older adults.

研究背景 本研究探讨了舒适度（comfort, CMT）、便捷度（convenience, CNV）与美观度（aesthetics, AST）在适配步行性的适老化建成环境促成因素与老年人的三类结局指标——身体活动水平提升（increased physical activity level, IPL）、社交活动增加（increased socialization, ISL）以及生活质量改善（improved quality of life, IQL）之间的中介作用。本研究强调打造适老化环境以保障老年人福祉与生活质量的重要性，研究结果可为城市规划者与政策制定者推进可持续、包容性设计提供参考依据。
研究方法 本研究遵循实证主义范式，采用定量研究方法与横断面设计的调查策略。通过便利抽样法选取333名老年人作为研究样本，采用自填式问卷收集研究数据。
研究结果 假设检验结果显示，在各类促成因素中，适老化城市设计政策是影响最为显著的构念，对全部三类中介变量均产生正向作用。美观度对身体活动水平提升与社交活动增加均具有显著正向影响，而舒适度与便捷度则分别对身体活动水平提升与生活质量改善产生显著影响。
研究结论 本研究结果可为城市规划者与政策制定者优化适配步行性的建成环境对老年人的作用提供指引，助力提升老年人的身体活动水平、拓展社交活动并改善其生活质量。本研究为学术界与实务界提供了宝贵的研究视角，强调在推进可持续设计的同时需兼顾包容性，以促进老年人的福祉与生活质量提升。
