Values are derived at median intake levels by demographic subgroup. SEs are in (parenthesis). Population weights by sex, age and income status were obtained from the World Development Indicators Data Bank: https://databank.worldbank.org/data/reports.aspx?source=world-development-indicators#.^*p≤0.10; ^**p≤0.05; ^***p≤0.01.
*Price elasticities are based on 1% price changes. For instance, given a 1% SSB price increase in the lowest income countries, intake by women, age 20 falls by 0.90%. ‡Income deciles are based on the national income of the 164 countries included in the study. Each decile is comprised of 16 countries (except the four lowest deciles, which are each comprised of 17 countries). The per capita income range (PPP-adjusted in thousand US$) for each decile: (1st) $0.6-$1.5, (2nd) $1.5-$2.7, (3rd) $2.7-$5.3, (4th) $5.5-$8.0, (5th) $8.3-$10.8, (6th) $11.1-$15.2, (7th) $15.3-$20.3, (8th) $20.6-$29.4, (9th) $30.4-$40.9 and (10th) $41.3-$127.2.
PPP, purchasing power parity; SSB, sugar-sweetened beverage.
