促进健康饮食是预防慢性病发生和进展的有效公共卫生策略。然而，食品价格可能会阻碍健康饮食，特别是在农村社区。这项研究的目的是确定食品成本是否与营养质量，地理位置和月份有关。在肯塔基州的四个县，两个农村和两个城市的主要杂货店，在10个月的时间内，对92种食品的总体营养质量指数和成本进行了四次评估。重复测量方差分析被用来评估营养质量，县和月的食物成本的差异。在更有营养的食品中，城市地区的成本较低。在营养质量最高的四分之一食品中尤其如此。在所有的县，有一个模式，最高的每服务成本在第二个四分位数的营养质量，而更有营养的食物是便宜的。帮助个人提高识别和准备低成本高营养价值食物的能力的策略可能有效地改善饮食习惯，特别是在农村，贫困的食物沙漠。
Promotion of healthy eating is an effective public health strategy to prevent chronic disease incidence and progression. However, food prices can impede healthy eating, especially in rural communities. The purpose of this study was to determine whether food costs are associated with nutritional quality, geographic location, and month of year. The Overall Nutritional Quality Index and cost of 92 foods were assessed four times over a 10-month period in the primary grocery stores in four Kentucky counties, two rural and two urban. Repeated measures analysis of variance was used to assess differences in food costs by nutritional quality, county, and month. Among more nutritious food items, costs were lower in urban areas. This was particularly true among foods in the highest quartile of nutritional quality. Across all counties, there was a pattern of highest per-serving costs in the second quartile of nutritional quality, whereas more nutritious foods were less expensive. Strategies that help individuals improve the ability to identify and prepare less costly foods with high nutritional value may be effective in improving dietary habits, particularly in rural, impoverished food deserts.
