背景资料：越来越多的横截面、小样本研究导致了减少食物沙漠的政策策略，即通过限制快餐店和小食品店以及增加低收入社区的超市准入，来减少或减少很少或根本无法获得健康食品的社区。方法：我们使用了来自年轻人冠状动脉风险发展（CARDIA）研究的15年纵向数据，一组美国年轻成年人（基线年龄为18-30岁）（n=5115），与随时间变化的地理信息系统衍生的食物资源措施相关联。使用4个检查周期的重复测量（n = 15854人-检查观察）和条件回归（以个人为条件），我们将快餐消费、饮食质量和对水果和蔬菜推荐的坚持作为快餐连锁店、超市或杂货店可用性的函数进行建模（按人口计算）在被调查者住所1.00公里以内、1.00至2.99公里、3.00至4.99公里和5.00至8.05公里范围内。模型进行性别分层，控制个人的社会人口特征和邻里贫困，并测试个人层面income.Results的互动：快餐消费与快餐供应低收入受访者之间，特别是在1.00至2.99公里的家庭男性（系数，0.34，95%的置信区间，0.16-0.51）。更大的超市的可用性一般是无关的饮食质量和水果和蔬菜的摄入量，杂货店的可用性和饮食outcomes.Conclusion之间的关系是混合的：我们的研究结果提供了一些证据分区限制快餐店在3公里内的低收入居民，但建议增加食品商店可能需要补充或替代策略，以促进饮食行为的改变。
Background: A growing body of cross-sectional, small-sample research has led to policy strategies to reducefood deserts-neighborhoods with little or no access to healthy foods by limiting fast food restaurants and small food stores and increasing access to supermarkets in low-income neighborhoods.Methods: We used 15 years of longitudinal data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, a cohort of US young adults (aged 18-30 years at baseline) (n=5115), with linked time-varying geographic information system-derived food resource measures. Using repeated measures from 4 examination periods (n =15 854 person-examination observations) and conditional regression (conditioned on the individual), we modeled fast food consumption, diet quality, and adherence to fruit and vegetable recommendations as a function of fast food chain, supermarket, or grocery store availability (counts per population) within less than 1.00 km, 1.00 to 2.99 km, 3.00 to 4.99 km, and 5.00 to 8.05 km of respondents' homes. Models were sex stratified, controlled for individual sociodemographic characteristics and neighborhood poverty, and tested for interaction by individual-level income.Results: Fast food consumption was related to fast food availability among low-income respondents, particularly within 1.00 to 2.99 km of home among men (coefficient, 0.34; 95% confidence interval, 0.16-0.51). Greater supermarket availability was generally unrelated to diet quality and fruit and vegetable intake, and relationships between grocery store availability and diet outcomes were mixed.Conclusion: Our findings provide some evidence for zoning restrictions on fast food restaurants within 3 km of low-income residents but suggest that increased access to food stores may require complementary or alternative strategies to promote dietary behavior change.
