Objective: to describe the profile of self-inflicted violence reports among adolescents in the Notifiable Diseases Information System (Sistema de Informação de Agravos de Notificação, SINAN) from 2012 to 2022. Method: a descriptive epidemiological study based on secondary data from the SINAN, covering adolescents aged 10-19 years old. Data on gender, age group, region where the events took place, schooling level and race were analyzed. Results: a total of 824,430 self-inflicted violence cases were reported between 2012 and 2022, with prevalence among female adolescents (69%). The Southeast region concentrated most of the reports (44%) and the Northeast region had the highest Proportional Percentage Variation (216.66%). Conclusion: self-inflicted violence among adolescents in Brazil is a serious Public Health problem, with prevalence among girls. It is essential to implement public policies that promote mental health and prevent self-harm behaviors. The measures implemented by the Health at School Program and other intersectoral actions are relevant to supporting at-risk adolescents.
