Objective

To characterize adolescent and adult suicide attempts and self-harm reported in Santa Catarina, Brazil, from 2014 to 2018.

Methods

This was a cross-sectional descriptive study with data from the Notifiable Health Conditions Information System. The sociodemographic, clinical and type of self-inflicted violence characteristics among adolescents and adults were compared.

Results

Among the 8,859 notifications analyzed, suicide attempts predominated in relation to self-mutilation; self-inflected violence was more frequent in females, those of white skin color and with mental disorders; it occurred more at home, in both age groups. Among adolescents, repeated self-mutilation (83.3%) stood out, while among adults, repeated suicide attempts (50.6%) and suspected alcohol use (18.3%) at the time of violence stood out.

Conclusion

We identified high prevalence of attempted suicide among adolescents and adults; the characteristics of violence were similar between the age groups analyzed.
