This study aims to identify and analyse factors associated with food insecurity (FI), trends and spatial distributions for geographical strata. The hypothesis of worsening of the outcome of severe FI, measured by the Brazilian Food Insecurity Scale (EBIA) in households, as an effect of the crisis and/or the austerity policy, was investigated. The article involves studies with cross-sectional design and mixed ecological for spatio-temporal trends, based on 4 national IBGE surveys. A weight calibration procedure to match population distribution by gender and age group was adopted, as well as estimation and modelling methods that incorporate effects of the sample design. Poisson regression with robust estimation of variance was used to estimate prevalence ratios of severe FI at the etiological level. For the ecological level, two multilevel modelling approaches were employed for repeated measurements of strata: multiple log-log regression for associations; and modelling of splines for trend estimation. The findings point to impacts of the austerity policy adopted, with changes in trends in the Programa Bolsa Família - PBF (Family Benefit Programme - FBP) and on the increase in severe FI. It is projected that there will be an increase in FI and a shortfall in relation to achievement of the SDG no. 2 in 2030 by Brazil, despite the success obtained in 2014 for MDG no. 1.
