OBJECTIVE: To analyze the sociodemographic profile of notifications of intentional self-harm in Brazil, from 2011 to 2022. METHOD: Descriptive study based on secondary data from the Sistema de Informação de Agravos de Notificação - SINAN (Notifiable Diseases Information System). The analysis included variables such as year, region, age group, sex, race/color, education level, and place of occurrence. RESULTS: Between 2011 and 2022, notifications of self-inflicted injuries totaled 827,659, representing a 373.5% increase (n=827,659) in Brazil, with 47.90% of cases occurring in the Southeast region, especially in São Paulo (24.17%). Adults (41.80%) and adolescents (24.41%) are the most affected, with 69.04% being women. The majority of notifications (46.60%) involve white individuals, with 16.27% having completed high school, and occurring in residences (82.43%). CONCLUSION: The data reveals a significant increase, especially among young people and women. It reinforces the need for interventions focused on vulnerable populations.
