[Evolution of food insecurity in Mexican households: 2012-2016].

OBJECTIVE: To describe three relevant aspects of household food insecurity (FI) in Mexico: its magnitude, its distribution by social and nutritional vulnerability characteristics; its evolution between 2012 and 2016 and the effect of food assistance programs on FI in Mexican households.

MATERIALS AND METHODS: Data on 9 019 households were drawn from the 2016 National Health and Nutrition Survey (Ensanut 2016 for its Spanish initials) and were compared with data from the 2012 Ensanut. An analysis of differences in differences was made to measure the effect of food assis-tance programs on the evolution of FI.

RESULTS: As many as 69.5% of households were classified as FI. Families located in rural areas (78.0%) and residing in southern Mexico (76.3%). Households with support from a food assistance program experienced a decrease in moderate and severe FI between 2012 and 2016.

CONCLUSIONS: Findings can be used to design and target public policies seeking to improve food security governance in Mexico.
