ResumoHighlights•Ultra-processed foods are more expensive than fresh foods.•There is an inverse association between the price of ultra-processed foods and obesity.•A 1% increase in the price of ultra-processed foods would reduce 0.33% (95% CI: 0.20%–0.46%) of overweight.•A 1% increase in the price of ultra-processed foods would reduce 0.59% (95% CI: 0.36%–0.83%) of obesity.•Taxation is a tool to control obesity and related noncommunicable diseases.AbstractBackground and aimsTo estimate the relationship between the price of ultra-processed foods and prevalence of obesity in Brazil and examine whether the relationship differed according to socioeconomic status.Methods and resultsData from the national Household Budget Survey from 2008/09 (n = 55 570 households, divided in 550 strata) were used. Weight and height of all individuals were used. Weight was measured by using portable electronic scales (maximum capacity of 150 kg). Height (or length) was measured using portable stadiometers (maximum capacity: 200 cm long) or infant anthropometers (maximum capacity: 105 cm long). Multivariate regression models (log-log) were used to estimate price elasticity. An inverse association was found between the price of ultra-processed foods (per kg) and the prevalence of overweight (Body mass index (BMI) ≥25 kg/m2) and obesity (BMI ≥30 kg/m2) in Brazil. The price elasticity for ultra-processed foods was −0.33 (95% CI: −0.46; −0.20) for overweight and −0.59 (95% CI: −0.83; −0.36) for obesity. This indicated that a 1.00% increase in the price of ultra-processed foods would lead to a decrease in the prevalence of overweight and obesity of 0.33% and 0.59%, respectively. For the lower income group, the price elasticity for price of ultra-processed foods was −0.34 (95% CI: −0.50; −0.18) for overweight and −0.63 (95% CI: −0.91; −0.36) for obesity.ConclusionThe price of ultra-processed foods was inversely associated with the prevalence of overweight and obesity in Brazil, mainly in the lowest socioeconomic status population. Therefore, the taxation of ultra-processed foods emerges as a prominent tool in the control of obesity.
