Abstract:
Ensuring independent mobility for older adults has become a public health and social concern in China owing to its rapidly aging population. To explore independent mobility trends among older adults and the impact of sociodemographic characteristics in recent years, this study used data from the Chinese Longitudinal Healthy Longevity Survey from 2012 to 2018, combined with binomial logit regression and CatBoost-Shapley additive explanation (SHAP) method to analyze the relationship between independent mobility and sociodemographic characteristics under bus- and walking-oriented environments. Study findings indicated that age and gender significantly affected the independent mobility of older adults. Policymaking should prioritize the needs of older adults, focusing on age and gender differences. Additionally, living expense adequacy significantly influenced independent mobility. Policies should substantially support economically disadvantaged older adults, ensuring their basic needs are met through subsidies and other measures. Moreover, the study found a notable impact of widowhood on independent mobility, suggesting enhanced social care and mental health support for widowed older adults, especially those who are long-lived. The outcomes of this study provided evidence for policymakers, which are beneficial for developing elderly-friendly travel policies to ensure and enhance the quality of life and independent mobility of older adults.
随着中国人口的快速老龄化，确保老年人独立行动已成为一个紧迫的公共卫生和社会问题。为探索近年来老年人独立出行能力的变化趋势及社会人口特征对其的影响，采用2002—2018年中国老年健康长寿研究的数据，结合二项logit回归与CatBoost‑SHAP方法，分析公交与步行导向环境下老年人独立出行能力与社会人口特征的作用关系。结果表明，年龄和性别是影响老年人独立出行能力的最关键因素，应优先关注高龄群体和性别差异。此外，生活费用充足程度对独立出行能力有显著影响，应着重支持经济困难的老年群体，通过提供生活补贴等措施来保障其基本生活需求。丧偶对独立出行能力的影响日益加剧，需加强对丧偶老年人的社会关怀，尤其是对长寿老年人的关注。研究成果为政策制定者提供了实证依据，有助于推动老年人友好出行政策的制定，从而保障老年人的独立出行能力并提升其生活质量。
