Resumen

Introduction This study assesses the impact on prices of the 2016 Chilean comprehensive food policy package, centred around front-of-package warning labels for food and beverages high in saturated fats, sugars, calories and/or salt, on food and beverage prices, labelled or not. Methods Data from Kantar WorldPanel Chile, from January 2014 to December 2017, were used. The methodology implemented was interrupted time series analyses with a control group on Laspeyres Price Indices on labelled food and beverage products. Results After the regulations were implemented, prices among different categories of products (eg, high-in; reformulated but still high-in; reformulated and not high-in; not high-in) did not change with regulations relative to the control group. Specific price indices (relative to the control group) for households from different socioeconomic strata remained unchanged. Conclusions Even where reformulation was extensive, we found no evidence that it was associated with price changes, at least during Chile's first year and a half of regulation implementation.
