Sugar-sweetened drink tax tied to sustained drop in purchase
Noting that Mexico implemented a tax on sugar-sweetened beverages on Jan. 1, 2014, M. Arantxa Cochero, Ph.D., from the National Institute of Public Health in Cuernavaca, Mexico, and colleagues estimated changes in beverage purchases for 2014 and 2015 using store purchase data for 6,645 households from January 2012 to December 2015. Using two models, the authors estimated the changes in purchases of taxed and untaxed beverages in the study period, comparing 2014 and 2015 purchases with predicted purchases based on trends in 2012 to 2013.
The researchers observed a 5.5 percent decrease in the purchase of taxed beverages in 2014 and a 9.7 percent decrease in 2015, resulting in an average decrease of 7.6 percent. In both years, the largest decreases in purchases of taxed beverages were seen for households at the lowest socioeconomic level. During the study period there was a 2.1 percent increase in purchases of untaxed beverages.
"Findings from Mexico may encourage other countries to use fiscal policies to reduce consumption of unhealthy beverages along with other interventions to reduce the burden of chronic disease," the authors write.
