众所周知，食品价格影响个人的购买和消费决策；然而，在使用美国多个地区的数据时，很少有人研究个人所在社区的健康食品相对于不健康食品的价格是否与整体饮食质量相关。个人层面的横截面数据来自动脉粥样硬化的多种族研究（考试 5，2010-2012 年，n = 2765）；食物频率调查问卷评估饮食。超市食品/饮料价格来自 Information Resources Inc.（n = 794 家超市）。对于每个人，计算该人居住地址三英里范围内的超市的健康食品（蔬菜、水果、乳制品）和不健康食品（苏打水、糖果、咸味零食）的选定指标的平均价格及其比率。逻辑回归估计了与健康与不健康价格比相关的高质量饮食（2010 年健康饮食指数前五分位）的比值比，并根据个人和社区特征进行了调整。敏感性分析使用工具变量（IV）方法。平均每份健康食品的成本几乎是不健康食品的两倍（平均健康与不健康比率 = 1.97 [SD 0.14]）。健康与不健康的价格比越大，获得高质量饮食的可能性越低（比率每增加一个 SD，OR = 0.76，95% CI = [0.64–0.9]）。 IV 分析在很大程度上证实了这些发现，尽管正如 IV 调整所预期的那样，置信区间很宽（OR = 0.82 [0.57–1.19]）。解决健康食品和不健康食品之间巨大价格差异的政策可能有助于改善美国的饮食质量。
It is known that the price of food influences the purchasing and consumption decisions of individuals; however, little work has examined if the price of healthier food relative to unhealthier food in an individual’s neighborhood is associated with overall dietary quality while using data from multiple regions in the United States. Cross-sectional person-level data came from The Multi-Ethnic Study of Atherosclerosis (exam 5, 2010–2012, n = 2765); a food frequency questionnaire assessed diet. Supermarket food/beverage prices came from Information Resources Inc. (n = 794 supermarkets). For each individual, the average price of select indicators of healthier foods (vegetables, fruits, dairy) and unhealthier foods (soda, sweets, salty snacks), as well as their ratio, was computed for supermarkets within three miles of the person’s residential address. Logistic regression estimated odds ratios of a high-quality diet (top quintile of Healthy Eating Index 2010) associated with healthy-to-unhealthy price ratio, adjusted for individual and neighborhood characteristics. Sensitivity analyses used an instrumental variable (IV) approach. Healthier foods cost nearly twice as much as unhealthier foods per serving on average (mean healthy-to-unhealthy ratio = 1.97 [SD 0.14]). A larger healthy-to-unhealthy price ratio was associated with lower odds of a high-quality diet (OR = 0.76 per SD increase in the ratio, 95% CI = [0.64–0.9]). IV analyses largely confirmed these findings although—as expected with IV adjustment—confidence intervals were wide (OR = 0.82 [0.57–1.19]). Policies to address the large price differences between healthier and unhealthy foods may help improve diet quality in the United States.
