背景 改善进入超市的机会已被证明可以改善某些饮食结果，但几乎没有证据表明对儿童有这种影响。与此相关的是，缺乏评估结构变化（即以前的食物荒漠中的超市）对家庭环境的影响及其与儿童饮食关系的研究。目的评估在食物荒漠中引入新超市后家庭环境对儿童饮食的相对影响。方法在随机选择的一组生活在食物荒漠中的家庭中，对全服务超市开业前后的父母饮食进行评估。在商店开业后的某个时间点对家庭环境和儿童水果和蔬菜的摄入量进行了测量。使用结构方程模型来估计随访时父母膳食质量的变化与家庭环境中儿童饮食摄入量之间的路径。结果超市开业后父母的饮食改善与拥有更好的家庭环境（beta = 0.45，p = 0.001）以及通过较高的家庭营养和体力活动得分（beta = 0.25，p = 0.02).结论旨在改善资源匮乏社区饮食的政策解决方案应考虑家庭环境的重要性。
BackgroundImproving access to supermarkets has been shown to improve some dietary outcomes, yet there is little evidence for such effects on children. Relatedly, there is a dearth of research assessing the impact of a structural change (i. e. supermarket in a former food desert) on the home environment and its relationship with children's diet.ObjectiveAssess the relative impact of the home environment on children's diet after the introduction of a new supermarket in a food desert.MethodsAmong a randomly selected cohort of households living in a food desert, parental diet was assessed before and after the opening of a full-service supermarket. The home environment and children's intake of fruits and vegetables was measured at one point - after the store's opening. Structural equation models were used to estimate the pathways between changes in parental dietary quality at follow-up and children's dietary intake through the home environment.ResultsParental dietary improvement after the supermarket opened was associated with having a better home environment (beta = 0.45, p = 0.001) and with healthier children's dietary intake (beta = 0.46, p< 0.001) through higher family nutrition and physical activity scores (beta = 0.25, p = 0.02).ConclusionsPolicy solutions designed to improve diet among low-resource communities should take into account the importance of the home environment.
