Trend in mortality due to external causes in the State of Espírito Santo, Brazil, from 1994 to 2005

Abstract

The aim of this study was to analyze the trend in mortality due to external causes in the State of Espírito Santo, Brazil, from 1994 to 2005, according to specific groups (traffic injuries, poisoning, intentional self-harm, assault), age group and gender. The trend analysis was performed with polynomial regression models, based on data from the Brazilian Ministry of Health's Mortality Information System. For all external causes, the trend was not statistically significant, but when it was stratified by gender and age group the results showed a downward trend in some strata. According to gender, the yearly increase in mortality rate was higher for men. In general, this increase was observed in all age groups. For traffic injuries, there was a decrease in the mortality rate, mainly for men. There was a decrease in deaths from poisoning for both men and women. Intentional self-harm showed an upward trend, especially for 50 and over age group. As a specific group, assault also showed a significant upward trend for under-34 age groups and for men.
