遵守《美国人饮食指南》(DGA)可能涉及更高的饮食成本。这项研究评估了西雅图肥胖研究(SOS III)中成年参与者(N=768)的食物支出和饮食质量的两项指标之间的关系。所有参与者都完成了社会人口和食物支出调查以及弗雷德·哈奇食物频率问卷。膳食摄入量与当地超市价格相结合，以估计个人水平的饮食成本。健康饮食指数(HEI-2015)衡量的是对DGA的遵从性。使用具有稳健标准误差的广义估计方程进行的多元线性回归表明，较低的食物支出与较年轻的年龄、西班牙裔种族和较低的社会经济地位相关。尽管HEI-2015得分较高与每2000千卡的饮食成本较高相关，但观察到了很大的个体差异。在调整后的模型中观察到了正的曲线关系。在较低成本的饮食中，每月成本增加100美元(从150美元增加到250美元)与HEI-2015年20.6%的增长相关。对于较高水平的饮食成本(从350美元到450美元)，回报递减(HEI-2015年增长2.8%)。这些发现表明，在较低端增加食品支出最有可能改善饮食质量。
Adherence to the Dietary Guidelines for Americans (DGA) may involve higher diet costs. This study assessed the relation between two measures of food spending and diet quality among adult participants (N = 768) in the Seattle Obesity Study (SOS III). All participants completed socio-demographic and food expenditure surveys and the Fred Hutch food frequency questionnaire. Dietary intakes were joined with local supermarket prices to estimate individual-level diet costs. Healthy Eating Index (HEI- 2015) scores measured compliance with DGA. Multiple linear regressions using Generalized Estimating Equations with robust standard errors showed that lower food spending was associated with younger age, Hispanic ethnicity, and lower socioeconomic status. Even though higher HEI-2015 scores were associated with higher diet costs per 2000 kcal, much individual variability was observed. A positive curvilinear relationship was observed in adjusted models. At lower cost diets, a $100/month increase in cost (from $150 to $250) was associated with a 20.6% increase in HEI-2015. For higher levels of diet cost (from $350 to $450) there were diminishing returns (2.8% increase in HEI- 2015). These findings indicate that increases in food spending at the lower end of the range have the most potential to improve diet quality.
