Despite substantial literature on how to improve the food environment for children, there has been little work examining how price promotions, nutrient-related claims, and their interactions might be associated with the nutrient profile of food purchases, particularly for lower-income and racial/ethnic minority populations. This study will address these gaps using 2008-2012 data for a demographically representative panel of over 40,000 U.S. household with children from the IRI National Consumer Panel, a large transaction-level database. Specific aims of this project are to: 1) describe characteristics of U.S. households with children who respond to price promotion and/or nutrition-related claims in key product groups; 2) quantify the associations between price promotions, nutrition-related claims, and the interactions between price promotions and claims on the nutrient profile of food purchases in key product groups; and 3) examine whether the response to price promotions, nutrition-related claims, and the interaction of price promotions and claims varies by race/ethnicity, income, and other characteristics such as access to various food sources. The investigator will use varying statistical measures for each aim, including a series of matching and clustering techniques and a dynamic quadratic almost ideal demand system (QAID).

No Fat, No Sugar, No Salt…No Problem? Prevalence of “Low-Content” Nutrient Claims and Their Associations with the Nutritional Profile of Food and Beverage Purchases in the United States
Nutrient content claims, which characterize the level of a nutrient in a food (e.g., “low-sugar”), are a commonly used marketing tactic. The association between claims, the nutritional quality of products, and consumer purchases is unknown. This study examined low-content nutrient claims on more than 80 million packaged food and beverage … More
