BEZERRA FILHO, José Gomes et al. Socio-demographic determinants of suicide in the State of Rio de Janeiro, Brazil, 1998-2002. Cad. Saúde Pública [online]. 2012, vol.28, n.5, pp.833-844. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2012000500003.
Epidemiology has identified violence as a major worldwide public health concern. Suicide is classified as violence. This study analyzes the association between suicide and socio-demographic factors. The methodological design was ecological, using correlation techniques and backward multiple linear regression. Normality of the residuals in the final model was analyzed. Proportional mortality in relation to total deaths was identified as the best outcome for modeling (R2 = 0.41). The resulting variables were: % Pentecostal religion, % single marital status in the population over 10 years of age, mean years of schooling, altitude of the municipality, % homes without latrines, % population over 10 years of age working in the educational sector, and % population over 10 years with per capita earnings up to one minimum wage. All these variables were statistically significant at 5%. The results support the idea of the influence of extrinsic causal factors in determination of suicide.
