Epidemiological profile, temporal trend and spatial analysis of the mortality of traumatized pedestrians in land transport collision in Alagoas, Brazil, 2007-2016

Abstract

Background: The pedestrians, along with cyclists and motorcyclists constitute the group most vulnerable to traffic collision in Brazil and worldwide. We analyzed the epidemiological profile, trend and geographic distribution of pedestrian mortality in land transport collision in Alagoas, Brazil, 2007-2016. Methods: Ecological study including all pedestrian deaths in transport collision in Alagoas, Brazil, 2007-2016 (code V00 to V09 of the international classification of diseases). Sociodemographic variables and mortality rates according to sex were analyzed. For statistical analysis we used the inflection point regression model, the Local Empirical Bayesian Model and the spatial scan statistic. Results: In the period, there were 1135 pedestrian deaths, highlighting: male gender (76.38%), age> 50 years (36.92%) and brown race (82.47%). The specific mortality rate in the general population decreased from 7.56/100,000 in 2007 to 1.13/100,000 in 2016 (APC -17.6%, 95%CI -21.3 to -13.2, p<0.001). In the male population, the rate went from 12.15 to 1.77/100,000 (APC -18.0%, 95%CI 21.8 to 13.9, p<0.001). On the other hand, in the female population, the downward trend only occurred from 2013 (APC -30.4%, 95%CI -48.2 to -6.4, p<0.001), whose mortality rate reached 0.55/100,000 in 2016. Pedestrian mortality is a major public health problem in Alagoas, with emphasis on male mortality and geographic concentration in the central part of the state. Conclusions: Pedestrian mortality is a major public health problem in Alagoas, with emphasis on male mortality and geographic concentration in the central part of the state.
