O mapa silencioso da dor: análise do impacto do suicídio na expectativa de vida brasileira

Abstract

This study investigates shifts in Brazil's mortality structure during the 2014 to 2024 decade, focusing on the impact of external causes. Applying the competitive risk model proposed by Chiang (1968), the research evaluated the theoretical gain in life expectancy resulting from the elimination of suicide as a cause of death in 2024. Methodologically, standardized crude rates were calculated to eliminate distortions inherent to age composition, and life tables were developed based on gross and net probability scenarios. The findings indicate that the Southeast and Northeast regions presented the highest Crude Death Rates (CDR) throughout the period, with the Southeast reaching a peak of 0.57962 in 2024. The exclusion of suicide revealed a theoretical increase of 0.52 years (approximately six months) in life expectancy at birth for the year 2024. The gains were more pronounced among the male population (0.40 years at birth, compared to 0.12 years for females), indicating a higher vulnerability of men during productive ages.
