Análise da mortalidade por acidentes de transporte terrestre e agressões no semiárido brasileiro

Abstract

This study aimed to analyze the mortality from Land Transport Accidents and Aggressions in the Brazilian Semiarid region in 2015. Knowing that men are the most affected by external causes of death, it was sought to verify through life table models, the extent of the damage caused by the causes of mortality considered on the life expectancy results, which at birth was 68.01 years for men and 75.17 years for women. With the aid of the Potential Years of Life Lost indicator, the range of years of life lost due to premature death from both causes was verified, where in sum, men lost 499,672 years and women 75,677, also comparing possible similarities among the semiarid regions of the states. And in order to classify the micro-regions of the Brazilian Semiarid region in relation to the mortality patterns of the semiarid regions of their states, binary classifiers have been proposed for Land Transport Accidents and Aggressions based on the logistical model, generalizing them to new data through the K-fold cross-validation, where the accuracy and F1-score values for the LTA model reached means of 0.80 and 0.85 in the test set, respectively. For the Aggression model, the mean value of accuracy and F1-score in the test set was 0.78 for both measures.
