Abstract
Recent studies indicate the accepted concept of using land-use mix (LUM) to promote physical activity is ineffective and even counteractive in the Chinese context. Before considering LUM as a whole, different amenity types need to be respectively analyzed in relation to various functions and demands. This study aims to examine the specific associations between food-related amenities and perceived daily walking duration (WD) in small Chinese cities. Two interviewer-administered questionnaire surveys (n = 354) were conducted in Yuncheng and Suihua between 2017 and 2018. Logistic regression models were used to examine the associations of WD with seven different categories of food outlet at three levels of walking distance. The associations were further explored by food environment diversity and through two age groups. With the exception of café/tea house, the other six food outlets were positively associated with WD. After adjusting for socioeconomic variables, the associations of grocery store and supermarket weakened. Higher levels of food environment diversity were associated with a longer WD. Among the age groups, food outlets were more associated with older adults’ WD. This novel quantitative study suggests that increasing the number and heterogeneity of food-related amenities (including mobile street vendors) within a neighborhood can enhance physical activity in small Chinese cities.
摘要
最新研究表明，土地利用混合模式可以促进身体活动这一普遍观念在中国是无效的，甚至是起反作用的。将土地混合利用作为一个整体考虑之前，不同用地类型需要根据不同的功能和需求分别进行分析。本研究旨在探讨中国小城市中饮食设施和日常步行持续时间之间的特殊联系。2017至2018年间，分别在运城和绥化市进行了两项问卷调查(n= 354)。本研究采用逻辑回归模型，结合两个年龄层和食品环境多样性，深入分析了在三种步行距离下，步行持续时间与七类餐饮店之间的关系。除咖啡馆（茶馆）外，其余6家餐饮店与步行持续时间呈正相关。通过调整社会经济变量，我们发现步行时长和杂货店及超市之间的关联性有所减弱。同时，食品环境多样性越高，步行持续时间越久。对各年龄层的分析表明，食品销售点和老年人的步行时长有着更密切的联系。这项新的定量研究表明，在中国小型城市中，增加社区内与食品相关的设施(包括流动街头小贩)的数量和种类，可以提高人们的体育活动。
