Background:

Currently, there is a change in the causes of mortality towards noncommunicable diseases and external causes. However, there are no updated studies on the trend of premature mortality due to external causes (PMEC) in Chile and the underlying sociodemographic variables. The objective of this study was to evaluate the trend of PMEC in Chile between 1997-2014 and analyze its distribution according to sociodemographic variables.

Methods:

Ecological mixed study. The cause of death and demographic data of mortality databases and official population estimates of the government of Chile were used. The PMEC and main subcauses (traffic accidents, self-inflicted injuries and aggressions) were considered in the population between 15-64 years. Annual crudes and adjusted rates (direct method) were estimated between 1997-2014. The trend of adjusted rates was evaluated using Prais-Winsten regression.

Results:

There were 102.559 deaths from external causes during the period studied (22.1% of total mortality). The cases were concentrated in men (85.3%), in the group of 25-44 years (44.8%) and at the basic instruction level-without instruction (48,4%). The PMEC trend decreased significantly in general population (β=-1.18x100,000 inhab., 95%CI: -1.58,-0.78) and men (β=-2.25x100,000 inhab. 95%CI: -2.79;-1.7). In women, there were no significant changes in PMEC, however an increase in PM due to aggressions was observed (β=0.03x100,000 inhab. 95%CI: 0.002,0.05).

Conclusions:

During the study period, a decrease in MPCE could be observed, especially that caused by traffic accidents. However, it has not been possible to reduce in women, alerting the increase in MP due to aggressions.
