This study examines trends in the prevalence of price promotions among packaged food and beverage purchases, differences in prevalence by household race/ethnicity or income, and the association between price promotions and the nutritional profile of purchases. The cross-sectional study uses a dataset of 90 million purchases from 38,744 (2008) to 45,042 (2012) U.S. households in 2008–2012. Prevalence of price promotions among packaged food and beverage purchases increased by 8 percent and 6 percent, respectively, from 2008 to 2012, with both reaching 34 percent by 2012. Higher-income households had greater proportions of purchases with price promotions than lower-income households. Asian households had the highest proportion of purchases with any price promotion, followed by non-Hispanic whites. While total price-promoted packaged food purchases had higher mean energy, total sugar, and saturated fat densities than purchases with no price promotions, absolute differences were small. Overall, no clear associations emerged between presence of price promotions and nutritional quality of purchases.

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 StatesNutrient 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 purchases from a transaction-level database More
Analyzing the Associations between Price Promotions and Health Claims on the Nutrient Profile of Food PurchasesDespite 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 More
