Gračner T, Marquez-Padilla F, Hernandez-Cortes D, et al. - In 2014, a tax was implemented on sugar-sweetened beverages (SSBs) in Mexico resulting in increases in SSB prices by about 10% on average, but differently across cities. Researchers aimed at determining the impact of these changes in prices of SSBs on weight-related outcomes among adolescents.

• Researchers examined the associations overall and by gender among 12,654 adolescents aged 10 to 18 years born between 1999 and 2002 living in 39 cities in Mexico.

• Findings revealed a 3% relative decrease in prevalence of overweight or obesity among adolescent girls in correlation with a 10% increase in SSB prices.

• There appeared small improvements in weight-related outcomes.

• The improvements were largely evident in girls with heavier weight and in cities where price increases were greater than 10% after the tax.

• Overall noticeable changes in weight-related outcomes may occur in correlation with large price increases.
