食物环境对不同收入群体生理健康的影响差异——以南京市为例

The Differences in the Impact of Food Environment on the Physiological Health of Different In come Groups:A Case Study of Nanjing

健康中国战略导向下,健康食品备受关注,分析食物环境对不同收入群体生理健康的影响差异成为新的研究视角。在剔除就业地食物环境的干扰后,总结食物环境对生理健康的作用路径,构建多层线性模型分析主客观食物环境、饮食行为、体力活动、自选择机制、个人属性对居民超重的影响,发现:低收人群体和中高收人群体在超重比例、个人属性、食物环境、饮食行为方面差异较大;王观食物环境对超重的影响作用于全体居民,而客观食物环境对超重的影响仅作用于低收人群体;个人属性仅对低收入群体超重产生影响;体力活动与健康管理可以减少居民超重。从健康公平出发,验证了可以通过食物环境干预居民生理健康,针对不同群体提出差异化的健康促进策略。

The attention of healthy foods is improving under the guidance of Healthy China.It is a new research perspective to analyze the differences in the impact of food environment on the physiological health of different income groups.The study controlled for the influence of food environment in the employment area and summarized the path of food environment affecting physiological health.Multilevel linear models were estimated to explore the influence of subjective and objective food environment,diet,physical activity,self-selection and personal attributes on overweight of residents.Results showed that lowincome groups and middle-high-income groups had significant differences in overweight ratio,personal attributes,food environment and diet.Subjective food environment affected overweight in all residents,although the impact of the objective food environment on overweight only affects the low-income groups.Individual attributes only affected the overweight of low-income groups,and physical activity and health management reduced overweight among residents.The study shows that the food environment can improve the physical health of residents and propose differentiated healthy promotion strategies for different groups.
