Deal or no deal? The prevalence and nutritional quality of price promotions among U.S. food and beverage purchases.

ABSTRACT:

Objective

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.

Design

This cross-sectional study utilizes a dataset of 90 million purchases from 38,744 (2008) to 45,042 (2012) US households in 2008-2012. Chi-square tests were used to examine whether the proportion of purchases with price promotions changed over time or differed by household race/ethnicity or income. T-tests were used to compare purchased products' nutritional profiles.

Results

Prevalence of price promotions among packaged food and beverage purchases increased by 8% and 6%, respectively, from 2008
