OBJECTIVE To evaluate the potential impact of sugar-sweetened beverage (SSB) taxes on overweight and obesity prevalence in countries of different income classifications. DESIGN Systematic review following PRISMA guidelines (PROSPERO number CRD42020161612). Five databases (Cochrane Library, Embase, LILACS (via Virtual Health Library) and MEDLINE (via PubMed), and Web of Science were searched, from January 2009 up to December 2019. Articles that reported changes in purchases, sales, intake, body weight, BMI, overweight and/or obesity prevalence due to a tax on, or price change in SSBs were included. SETTING Studies conducted in countries of different income classifications. PARTICIPANTS The search yielded 8,349 articles of which twenty-one met inclusion criteria. RESULTS Among the 16 studies selected, only 2 did not show that consumption, sales and purchase decreased as the price of SSBs increased. In 8 of the 13 studies selected, a positive effect of an SSB tax on decreasing overweight and obesity prevalence was expected. It is estimated that a 20% taxation on SSBs would result in a greater decrease in the prevalence of overweight and obesity compared to a 10% rate. Studies with no significant effect of taxing on sales, purchases, consumption and prevalence of obesity were from high-income countries, while significant effects of taxing on reducing purchase, consumption and/or obesity prevalence were found in studies from upper-middle and middle-income countries.
