Global patterns in price elasticities of sugar-sweetened beverage intake and potential effectiveness of tax policy: a cross-sectional study of 164 countries by sex, age and global-income decile.

Objective: To quantify global relationships between sugar-sweetened beverage (SSB) intake and prices and examine the potential effectiveness of tax policy.

Design: SSB intake data by country, age and sex from the Global Dietary Database were combined with gross domestic product and price data from the World Bank. Intake responsiveness to income and prices was estimated accounting for national income, age and sex differences.

How income and food prices influence global dietary intakes by age and sex: evidence from 164 countries.

Background: While income and prices are key drivers of dietary choices, how their influence varies by food category, nation, and demographics is not well established. Based on intake data for 164 countries and 11 food categories, we examined how income and food prices relate to food intake globally, including by world region, age, and sex.

Methods: We used 2010 intake data from the Global Dietary Database, the first database of consumption estimates for major food categories by country, age, and sex.
