Objective: To examine patterns of taxed and untaxed food and beverage shopping across store-types after Mexico’s sugary drink and non-essential food taxes, the nutritional quality of these patterns, and the socio-economic characteristics associated with them.Design: We performed k-means cluster analyses using households’ percentage of food and beverage purchases from each store-type (i.e. convenience stores, traditional shops [(e.g. bodegas, tiendas, mom- and-pop shops], supermarkets, wholesalers, and others). We calculated adjusted mean proportions of taxed and untaxed products (ml or g/capita/day) purchased in each pattern. We studied the associations between households’ SES and shopping-patterns using multinomial logistic regressions. Within shopping-patterns, we obtained mean volumes and proportions of taxed and untaxed food and beverage subgroups and calculated the proportion of products purchased at each store-type.
Setting: Mexico.
Participants: Urban Mexican households (n=5,493) from the Nielsen Mexico Consumer Panel Survey 2015.
Results: We found 4 beverage shopping-patterns and 3 food shopping-patterns, driven by the store-type where most purchases were made. For beverages, 48% of households clustered in the Traditional pattern and purchased the highest proportion of taxed beverages. Low-SES households had the highest probability of clustering in the Traditional beverage shopping-pattern. For foods, 35% of households clustered into the Supermarket pattern. High-SES households had the highest probability of clustering in the Supermarket food shopping-pattern.
Conclusions: The combination of store-types where Mexican households purchase packaged foods and beverages varies. However, households in all shopping-patterns and SES purchase taxed beverages mainly at traditional stores. Store-level strategies should be developed to intervene on traditional stores to improve the healthfulness of purchases.
