Muhammad A, et al. - Via conducting a cross-sectional study in 164 countries, experts quantified global associations between sugar-sweetened beverage (SSB) consumption and prices, and analyzed the potential efficiency of tax policy. They combined SSB intake data by country, age and sex from the Global Dietary Database with gross domestic product and price data from the World Bank. Intake responsiveness to income and prices was estimated, adjusting for national income, age and sex differences. In lowest-income countries, own-price responsiveness was the greatest, ranging from −0.70 for women, age 50, to −1.91 for men, age 80. Responsiveness was as high as −0.49; however, it was mostly insignificant for elderly adults, in the highest-income countries. Overall, elasticities were most powerful (more negative) at the youngest and oldest age groups, and frequently insignificant for middle-aged adults, especially in middle-income and high-income countries. Gender variations were often negligible. In the lowest-income countries, potential consumption decreases from a 20% tax ranged from 14.5% in women, 35 ≤ age < 60, to 24.9% in men, age ≥ 60. Consumption decreases reduced with country income overall and was often insignificant for middle-aged adults. Hence, the conclusions determined the global price-responsiveness of SSB consumption by age and sex, implicating ongoing policy discussions on potential impact of taxes.
