Prevalence of child and adolescent psychiatric disorders in Santiago, Chile: a community epidemiological study

Abstract

Purpose  

To determine the prevalence of DSM-IV psychiatric disorders in a representative sample of children and adolescents living
in Santiago, Chile, as part of a national sample.

Method  

Subjects aged 4–18 were selected using a stratified multistage design. First, ten municipalities/comunas of Santiago were selected; then the blocks, homes, and child or adolescent to be interviewed were chosen. Psychology graduate
students administered the Spanish-language, computer-assisted version of DISC-IV that estimated DSM-IV 12-month prevalence.

Results  

A total of 792 children and adolescents were evaluated, with a participation rate of 76.7%. The most stringent impairment
DSM-IV DISC algorithm for psychiatric disorders revealed a prevalence of 25.4% (20.7% for boys and 30.3% for girls). The majority
of the diagnoses corresponded to anxiety and affective disorders. Prevalence was higher in children aged 4–11 (31.9%) than
in adolescents aged 12–18 (18.2%). This difference was mainly accounted for by disruptive disorders in the younger age group.
Anxiety disorders had the highest prevalence, although impairment was low. In contrast, most children and adolescents with
affective disorders were impaired.

Conclusions  

In Santiago, the prevalence of psychiatric disorders in children and adolescents was high. This study helps raise awareness
of child and adolescent mental health issues in Spanish-speaking Latin America and serves as a basis for improving mental
health services.
