Diets low in fruits and vegetables and/or high in fast foods are associated with obesity and chronic diseases. Such diets may relate to different aspects of neighborhood food environments. We sought to evaluate if people's perceptions of their neighborhood food environment are associated with reported fruit-and-vegetable and fast-food consumption.
Cross-sectional analysis of a community health survey from Philadelphia, PA and four surrounding suburban counties (n = 10,450 individuals). We used mixed-effects multi-level Poisson models, nesting individuals within neighborhoods-i.e. census tracts (n = 991).
Negative perceptions of the food environment (perceived difficulty finding fruits and vegetables, having to travel outside of one's neighborhood to get to a supermarket, and perceived poor grocery quality) were each directly associated with fast-food consumption (incident rate ratios [IRRs] 1.31, 1.06, 1.20; p < 0.001, 0.04, < 0.001 respectively), but not significantly associated with fruit-and-vegetable consumption.
Perceived difficulty finding or accessing produce and high-quality groceries may support the eating of more fast food. Neighborhoods where food-environment perceptions are worst might benefit from interventions to improve availability, accessibility, and quality of healthy foods, towards shifting consumption away from fast foods.
低水果和蔬菜摄入、高快餐摄入的饮食与肥胖和慢性病有关。这种饮食可能与邻里食品环境的不同方面有关。我们试图评估人们对邻里食品环境的看法是否与报告的水果和蔬菜以及快餐消费有关。
对宾夕法尼亚州费城和四个周边郊区县的社区健康调查进行横断面分析（n=10450 人）。我们使用混合效应多级泊松模型，将个体嵌套在邻里中，即普查区（n=991）。
对食品环境的负面看法（认为难以找到水果和蔬菜、必须到邻里以外的地方去超市，以及认为杂货店的商品质量差）均与快餐消费直接相关（快餐消费的发生率比 [IRR] 分别为 1.31、1.06、1.20；p<0.001、0.04、<0.001），但与水果和蔬菜消费无显著关联。
难以找到或获取农产品和高质量杂货的看法可能会支持更多快餐的食用。食品环境看法最差的邻里可能受益于改善健康食品供应、可及性和质量的干预措施，以减少快餐消费。
