Despite the growth in empirical research on neighborhood environmental characteristics and their influence on children's diets, physical activity, and obesity, much remains to be learned, as few have examined the relationship between neighborhood food availability on dietary behavior in children, specifically. This analysis utilized data from a community-based, cross-sectional sample of children ( = 199) that was collected in New Orleans, Louisiana, in 2010. This dataset was linked to food environment data to assess the impact of neighborhood food access as well as household and parent factors on children's diets. We observed a negligible impact of the neighborhood food environment on children's diets, except with respect to fast food, with children who had access to fast food within 500 m around their home significantly less likely (OR = 0.35, 95% CI: 0.1, 0.8) to consume vegetables. Key parental and household factors did play a role in diet, including receipt of public assistance and cooking meals at home. Children receiving public assistance were 2.5 times (95% CI: 1.1, 5.4) more likely to consume fruit more than twice per day compared with children not receiving public assistance. Children whose family cooked dinner at home more than 5 times per week had significantly more consumption of fruit (64% vs. 58%) and vegetables (55% vs. 39%), but less soda (27% vs. 43%). Findings highlight the need for future research that focuses on the dynamic and complex relationships between built and social factors in the communities and homes of children that impact their diet in order to develop multilevel prevention approaches that address childhood obesity.
尽管关于邻里环境特征及其对儿童饮食、身体活动和肥胖影响的实证研究有所增加，但仍有许多有待了解之处，因为很少有研究专门考察邻里食物供应与儿童饮食行为之间的关系。本分析利用了2010年在路易斯安那州新奥尔良市收集的基于社区的儿童横断面样本数据（n = 199）。该数据集与食物环境数据相关联，以评估邻里食物获取以及家庭和父母因素对儿童饮食的影响。我们观察到邻里食物环境对儿童饮食的影响微乎其微，除了快餐方面，家周围500米内可获取快餐的儿童食用蔬菜的可能性显著降低（OR = 0.35，95% CI：0.1，0.8）。关键的父母和家庭因素在饮食中确实起到了作用，包括获得公共援助和在家做饭。与未获得公共援助的儿童相比，获得公共援助的儿童每天食用水果超过两次的可能性高出2.5倍（95% CI：1.1，5.4）。每周在家做晚餐超过5次的儿童食用水果（64%对58%）和蔬菜（55%对39%）的量显著更多，但饮用苏打水的量更少（27%对43%）。研究结果凸显了未来研究的必要性，即关注社区和家庭中影响儿童饮食的建筑和社会因素之间动态复杂的关系，以便制定解决儿童肥胖问题的多层次预防方法。
