摘　　要：基于城市POI数据、中国城市统计年鉴数据以及中国健康与养老追踪调查数据,利用“个体-城市”多层回归模型,考察了城市食物环境对老龄人口健康的影响,并探索了个体生活方式的调节作用,以及城市食物环境对健康影响的异质性。通过构建城市健康食物可及性指数与多样性指数,发现健康食物可及与健康食物多样的提升均对老龄人口健康具有促进作用,健康食物多样比健康食物可及对提升老龄健康更重要;生活方式能够强化城市食物环境改善对老龄人口健康的正向影响;城市食物环境改善对非高龄、高收入、高教育水平以及居住在西部地区和小城市的老龄群体影响较大。据此提出,重视城市食物环境的建设与提升,以及健康的生活方式,对增进老龄健康的重要作用,针对不同群体采取差异化干预措施将更好地发挥健康食物环境对老龄健康的正向影响。Combining the urban POI data,China City Statistical Yearbook data,and the CHARLS data,this study discusses the effects of urban food environment on individual level health among the elderly.Applying a multi-level regression model,this study also explores the moderating effect of individual lifestyle,and further discusses the heterogenous effects of urban food environment.By constructing healthy food accessibility index and healthy food diversity index for each city,this study found that increases in both healthy food accessibility and healthy food diversity improved the health status of the elderly,and the healthy food diversity played a more important role than health food accessibility.Healthy lifestyle strengthened the positive impact of healthy food availability on the health of the elderly.The non-elderly,high-income,and high-educated individuals benefit more from the improvement of urban food environment.Furthermore,urban food environment affects the elderly living in west region and small cities more than those living in other regions.This study implies that urban food environment should be improved when promoting healthy ageing,and it is necessary to guide healthy individual lifestyle to strengthen the effects of food environment.Furthermore,different interventions should be designed for cities of different scales when improving urban food environment.
