Years of Life Lost Due to External Causes of Death in the Lodz Province,Poland

Background

The aim of the study is the analysis of years of life lost due to external causes of death, particularly due to traffic accidents and suicides.

Materials and Methods

The study material includes a database containing information gathered from 376,281 death certificates of inhabitants of the Lodz province who died between 1999 and 2010. The Lodz province is characterized by the highest mortality rates in Poland. The SEYLL_p (Standard Expected Years of Life Lost per living person) and the SEYLL_d (per death) indices were used to determine years of life lost. Joinpoint models were used to analyze time trends.

Results

In 2010, deaths due to external causes constituted 6.0% of the total number of deaths. The standardized death rate (SDR) due to external causes was 110.0 per 100,000 males and was five times higher than for females (22.0 per 100,000 females). In 2010, the SEYLL_p due to external causes was 3746 per 100,000 males and 721 per 100,000 females. Among males, suicides and traffic accidents were the most common causes of death (the values of the SEYLL_p were: 1098 years and 887 years per 100,000 people, respectively). Among females, the SEYLL_p values were 183 years due to traffic accidents and 143 years due to suicides (per 100,000 people).

Conclusions

A decrease in the number of years of life lost due to external causes is much higher among females. The authors observe that a growing number of suicides contribute to an increase in the value of the SEYLL_p index. This directly contributes to over-mortality of males due to external causes. The analysis of the years of life lost focuses on the social and economic aspects of premature mortality due to external causes.
