French SA, et al. - Via analyzing data from 202 urban households participating in a study about food shopping, researchers assessed the links between household income and the diet quality of household food purchases. They analyzed 14 days of food purchase receipt data using NDS-R software. Using the Healthy Eating Index 2010 (HEI 2010), they performed scoring of purchase data. Taking into account household income-to-poverty ratio, they assessed HEI total and subscores, as well as proportion of grocery dollars spent on food categories (eg, fruits, vegetables, sugar sweetened beverages). Remarkably higher HEI total scores, higher total vegetable scores, higher dairy scores, and lower proportion of grocery dollars spent on frozen desserts were reported for higher income households vs lower income households, after adjusting for education, marital status, and race. Overall, food purchases by lower income households comprised less healthful foods vs higher income households. Overall, food purchasing trends could be a mediator of income differences in dietary intake quality.
