Adolescent suicide trends in Brazil (2000-2022): An ecological analysis by sex, age, and suicide methods.

ABSTRACT:

Introduction

Suicide is the 3rd leading cause of death among Brazilian adolescents. Despite the rising rates, national studies on suicide trends still face methodological limitations and data quality issues. This study aimed to investigate adolescent suicide trends in Brazil.

Methods

An ecological time-series study was conducted to analyse suicide (ICD-10: X60-X84, Y87.0) trends among 10-19-year-old adolescents from 2000 to 2022, stratified by sex, age group, and self-harm method. Garbage code redistribution was applied to correct misclassified underlying causes of death. Corrected suicide rates were estimated and time trend analysis was performed using joinpoint regression.

Results

After the redistribution, 22,591 adolescent suicides were identified. Rates increased
