The food environment has been associated with fruit and vegetable consumption, however many studies utilize cross-sectional research designs. This study examined 3,473 participants in the Moving to Opportunity experiment, who were randomized into groups that affected where they lived. The relationship between the built environment, food prices and neighborhood poverty, assessed over four to seven years, on fruit or vegetable consumption was examined using instrumental variable analysis. Higher food prices and neighborhood poverty were associated with lower fruit or vegetable consumption. Policies and programs that address food prices should be implemented and evaluated for their effects on fruit and vegetable consumption.
食品环境与水果和蔬菜的消费有关，但许多研究采用的是横断面研究设计。本研究调查了“机遇迁居”实验中的 3473 名参与者，他们被随机分配到影响居住地点的小组中。本研究采用工具变量分析方法，研究了在四年到七年期间评估的建筑环境、食品价格和社区贫困与水果或蔬菜消费之间的关系。较高的食品价格和社区贫困与较低的水果或蔬菜消费有关。应实施并评估解决食品价格问题的政策和方案，以了解其对水果和蔬菜消费的影响。
