Pricing strategies to reduce population sugar-sweetened beverage consumption

This thesis explores the relationship between changes to sugary drink prices and beverage purchasing across the population and for different consumer groups. Using a variety of methods, results showed a) lower price responsiveness among more frequent sugary drink consumers and similar effects on purchasing behaviour across income groups, b) combining price changes with well-designed educational messages could deliver greater benefits to lower-income groups, and c) retailer and consumer acceptability is vital for feasible and sustainable healthy food retail strategies. These findings support the implementation of sugary drink pricing initiatives to reduce their consumption across the population and among lower-income groups.
