PINTO, Liana Wernersbach; PIRES, Thiago de Oliveira; SILVA, Cosme Marcelo Furtado Passos da and ASSIS, Simone Gonçalves de. Suicide mortality temporal trends in people aged 60 years or more in the Brazilian states: 1980 to 2009. Ciênc. saúde coletiva [online]. 2012, vol.17, n.8, pp.1973-1981. ISSN 1413-8123. http://dx.doi.org/10.1590/S1413-81232012000800008.
The scope of this paper is to determine the temporal evolution of mortality by suicide in people aged 60 or more per State in Brazil between 1980 and 2009. Historical mortality by suicide data (ICD-9 codes E950 to E959 and ICD-10 codes X60 to X84 and Y87.0) were obtained from the Mortality Information System (SIM / MS). Data regarding population counts were obtained from the Brazilian Institute of Geography and Statistics. In the assessment of temporal trends the Poisson regression model was used, in which the dependent variable was the number of deaths and the centralized calendar year was the explanatory variable. Statistically significant trends were considered those whose p-value was d" 0.05. The results revealed the presence of a statistically significant increasing trend in four states and a decrease in two (general population; 60 years or more). In the male population there was an increase in five states and a reduction in two. The female rate showed an increase in one state and a decrease in three. There was an increasing trend in Piauí, Ceará and Rio Grande do Norte and a reduction in Amazonas, Roraima, and São Paulo for people aged between 60 and 69. Increasing rates were observed in the population aged 70-79 in Piauí and decreasing trends in Roraima.
