Abstract
in English, Portuguese

This study aimed to analyze space-time distribution of the prevalence of food and nutritional insecurity (FNI) in the Brazilian Federative Units and their correlation with vulnerability markers. This is an ecological study, with data from the National Household Sample Survey (2004, 2009 and 2013) and Atlas Brazil (2010). A time analysis of the spatial distribution of FNI prevalence was performed. Moran's Index was used in bivariate spatial analysis. The prevalence of FNI have decreased along the years studied and showed a negative and moderate spatial correlation with the Human Development Index; a positive and moderate correlation with the percentage of the extremely poor, child mortality, social vulnerability index, human capital social vulnerability index; and positive and strong correlation with income and work social vulnerability index. We can conclude that there was a lower prevalence of FNI in the analyzed years and that the Brazilian territory showed two distinct patterns: territories with higher FNI prevalence and worse conditions as regards income, work and child health in the North and Northeast; and territories with lower FNI prevalence and lower vulnerability in the Midwest, Southeast and South.

O objetivo do estudo foi analisar a distribuição espaço-temporal da prevalência de IAN nas Unidades de Federação (UF) do Brasil e sua correlação com indicadores de vulnerabilidade. Estudo ecológico, com dados da Pesquisa Nacional Amostra de Domicílios (2004, 2009 e 2013) e do Altas Brasil (2010). Realizou-se análise temporal da distribuição espacial das prevalências de IAN. Na análise espacial bivariada foi utilizado o Índice de Moran. As prevalências de IAN diminuíram nos anos analisados e apresentaram correlação espacial negativa e moderada com o IDH; positiva e moderada com porcentagem de extremamente pobres, mortalidade infantil, índice de vulnerabilidade social, índice de vulnerabilidade social capital humano; positiva e forte com índice de vulnerabilidade social renda e trabalho. Conclui-se que houve diminuição da prevalência de IAN nos anos analisados e que o território brasileiro apresentou dois padrões distintos: territórios com maiores prevalências de IAN e piores condições de renda, trabalho e saúde infantil nas regiões Norte e Nordeste; e territórios com menores prevalências de IAN e menor vulnerabilidade nas regiões Centro-Oeste, Sudeste e Sul.
