External causes of death in younger than 18 years old in Portugal in the last 10 years - a retrospective analysis.

Pediatric mortality from external causes has been a worldwide concern in the last decades. In particular, the prevalence of accidental deaths is a key concern, especially traffic accidents. This is retrospective study based on autopsy reports of violent deaths in individuals younger than 18 years from 2014 to 2023 in Portugal, aimed at providing valuable insight in order to help formulate preventive strategies. There were 554 pediatric deaths due to exogenous causes, with a predominance of males (68,95%). Adolescents were the most prevalent age group. The leading cause of death was land transport injury (38,27%). Asphyxia-related deaths were predominant in younger age groups. Accidental deaths accounted for 76,71% of all cases. Preventable injury-related causes continue to be a major contributor to child mortality. The inconsistent mortality rates from various mechanisms emphasize the necessity for targeted and effective preventive measures. Above all, land transport accidents seem to be an issue in need of prompt intervention.
