Mortality trend due to intentionally self-inflicted injuries in Brazil from 2004 to 2014

<p></p><p>ABSTRACT Objective To analyze mortality trends by intentionally self-inflicted injuries according to the age groups and regions of Brazil. Methods This is an epidemiological study, ecological type of temporal series, using data from the Mortality Information System related to deaths from intentional self-inflicted injuries in the period of 2004 to 2014. Results Trend analysis indicated increase in mortality rates, whereas Brazil curve accentuated elevation (R2 = 0.678). The Southeast region showed the highest straight slope (R2 = 0.960), being higher then trend observed in Brazil. Mortality coefficients according age groups showed an increasing tendency for the range of 10 to 19 years (R2 = 0.429). In the age group of 20 to 29 years in the analyzed period there was no tendency for growth. However, there was an increase in the number of deaths from the year 2010. This group was evaluated in the period 2010-2014, thus evidencing an increasing trend for this group (R2 = 0.927). The results point to the growth of mortality coefficients by self-inflicted injuries in Brazil and in all its regions, with the age group being the most understood 10 to 19 years old, followed by the age group of 20 to 59 years and those over 60 years. Conclusion The results point to the increase in mortality coefficients due to intentional self-inflicted injuries in Brazil and all regions, the most vulnerable age group being 10 to 19 years old, followed by the age group of 20 to 59 years and those over 60.</p><p></p>
