Pedestrian Mortality in Espírito Santo: A Time Trend Analysis from 2009 to 2020

Traffic accidents are a significant public health issue. Pedestrians are considered the most vulnerable victims, showing the highest mortality rates. Thus, mortality rate indicators reflect the effectiveness of policies and safety measures applied to urban mobility. Therefore, the study objective is to identify trends in pedestrian mortality to foster an understanding of the local reality and to propose effective interventions for the safety and mobility of this population.

This ecological time-series study used secondary data from the Unified Health System Information System (DATASUS) on all traffic accident-related deaths in Espírito Santo, Brazil, from 2009 to 2020. Data were classified according to the 10th Revision of the International Classification of Diseases (ICD-10). Variables included sex (male; female), age group (in years: 0 to 80+), and victim type (pedestrian). Mortality rates were logarithmically transformed (base 10), and the Prais-Winsten regression model was employed using STATA 13.0.

A total of 1969 traffic accident-related deaths were recorded. Males accounted for 75% of deaths, individuals of mixed race (pardo) represented 57%, and 72% were unmarried. A significant reduction in mortality rates was observed across age groups, especially among individuals aged 0-24 years. Mortality trends remained stationary only among individuals aged 80 years and older. Overall, the mortality rate decreased throughout the study period, from 5.51 to 1.69 deaths per 100,000 inhabitants.

Pedestrian mortality rates from traffic accidents in Espírito Santo showed a decreasing trend, particularly among children and young people, while remaining stable among the elderly.
