目的 评估在高需求地区新建政府补贴超市对家庭食品供应和儿童饮食习惯的影响。设计采用双重差分研究设计。设置纽约市布朗克斯区的两个社区。结果收集于莫里萨尼亚（新超市开业的目标社区）和海布里奇（比较社区）。 对象 居住在莫里萨尼亚或海布里奇的 3-10 岁儿童的父母/照顾者。参与者是通过基线（超市开业前）和两个随访期（超市开业后五周和一年）的街头拦截招募的。结果分析基于 2172 项街头拦截调查和来自主要低收入少数族裔样本的 363 项饮食回忆。虽然在不同时间段内存在微小且不一致的变化，但在家中健康或不健康食品的供应情况或儿童饮食摄入量因超市而没有明显差异。结论在布朗克斯服务不足的社区引入政府补贴的超市并没有导致家庭食品供应量或儿童饮食摄入量的显着变化。鉴于服务不足的社区缺乏健康食品选择，并且需要促进获取的计划，需要进一步研究以确定健康食品零售扩张（单独或与其他策略结合）是否可以改善儿童及其家庭的食物选择。
Objective To assess the impact of a new government-subsidized supermarket in a high-need area on household food availability and dietary habits in children.Design A difference-in-difference study design was utilized.Setting Two neighbourhoods in the Bronx, New York City. Outcomes were collected in Morrisania, the target community where the new supermarket was opened, and Highbridge, the comparison community.Subjects Parents/caregivers of a child aged 3-10 years residing in Morrisania or Highbridge. Participants were recruited via street intercept at baseline (pre-supermarket opening) and at two follow-up periods (five weeks and one year post-supermarket opening).Results Analysis is based on 2172 street-intercept surveys and 363 dietary recalls from a sample of predominantly low-income minorities. While there were small, inconsistent changes over the time periods, there were no appreciable differences in availability of healthful or unhealthful foods at home, or in children's dietary intake as a result of the supermarket.Conclusions The introduction of a government-subsidized supermarket into an underserved neighbourhood in the Bronx did not result in significant changes in household food availability or children's dietary intake. Given the lack of healthful food options in underserved neighbourhoods and need for programmes that promote access, further research is needed to determine whether healthy food retail expansion, alone or with other strategies, can improve food choices of children and their families.
