Homicide mortality in border regions in the State of Paraná, Brazil

Abstract

A time series analysis was conducted to identify trends in homicide mortality in border regions in the State of Paraná, Brazil between 2002 and 2012. Homicide mortality rates were analyzed by sex, age group, region (border regions, non-border regions, and the state as a whole), and type of assault. Trend analysis was performed using polynomial regression. The findings showed that mortality rates were higher in the border regions; however the growth in homicide rates was greater in the non-border regions and in the state as a whole, with these states showing an upward trend in homicide rates (p < 0.001) and border regions showing a downward trend, although the latter was not significant. Mortality rates were higher among men across all regions and highest in the 20 to 29 age group. The findings regarding homicide rates in border regions provide compelling evidence of the urgent need for intersectoral prevention policies targeting the most affected groups.
