Abstract

Objective: To identify spatial clusters of suicide and the epidemiological profile in the microregion of Chapecó (SC), between 1996-2018. Methods: Exploratory ecological study, with data from the Mortality Information System. Specific suicide rates and relative risks (RR) were calculated with a 95% confidence interval (95%CI). For spatial analysis, the scan statistic was used. Results: There were 1,034 suicides (13.7/100,000 inhabitants), with a male/female ratio of 3.79. The age group ≥60 was at higher risk for both sexes. A high risk cluster was observed in the southwest region (RR=1.57) and a low risk cluster in the southeast, including Chapecó (RR=0.68). The risk of suicide among widowed (RR=3.05;CI95%:1.99;4.67), separated (RR=2.48;CI95%:1.44;4.27), and married (RR= 1.97;CI95%:1.54;2.51) were higher than among singles. The main methods was hanging (81.2%), followed by firearms (9.7%). Conclusion: There was a higher risk of suicide in the elderly, men and widowers. Hanging was the most frequent method and risk clustering was observed to the Southwest.
