Determinantes socioeconômicos do suicídio no Brasil e no Rio Grande do Sul no Século XXI

Abstract

This study aims to identify the socioeconomic factors related to high rates of suicide mortality in the cities of Brazil and, especially, in Rio Grande do Sul. The methodology employed involved methods for count data: Poisson regression, negative binomial regression, and quantile regression for count data. The results showed that among socioeconomic indicators developed by the FIRJAN, just the Health IFDH proved important in determining the suicide deaths in Brazilian cities. However, the suicides occurred in the cities of Rio Grande do Sul, in the period analyzed, not demonstrating being influenced by the Health and Education IFDH. In addition to presenting a positive relation with suicide deaths by self-inflicted violence, poverty is a major contributor in cities with high numbers of deaths. The association between the unemployment rate and the number of suicide deaths shows an inverse relationship; if the unemployment rate of cities increases, the tendency is to reduce deaths by suicide. It was also shown that one of the main factors affecting the number of suicide cases in Brazil and in Rio Grande do Sul is the level of agricultural dependence. Finally, it was possible to identify, also, that the characteristic color/ white and Indian race is among the main determinants of suicide deaths in Brazilian cities.
