Abstract

PURPOSE: To estimate the prevalence of intermittent explosive disorder (IED) in comorbidity with other psychiatric disorders and to describe the temporal sequencing of disorders in the São Paulo Metropolitan Area, Brazil.

METHODS: Data from the São Paulo Megacity Mental Health Survey, a population-based study of 5037 adult individuals, were analyzed. The World Health Organization Composite International Diagnostic Interview (CID 3.0) was used to assess lifetime DSM-IV disorders, including IED, with a response rate of 81.3%.

RESULTS: The majority (76.8%) of respondents with IED meet the criteria for at least one other psychiatric disorder, with a prevalence almost twice as high as that observed in individuals without IED. The prevalence of any anxiety, mood, impulse control or substance use disorders in respondents with IED was more than two times higher compared to those without IED, with prevalence ratios ranging from 2.1 (95% CI 1.74-2.48) to 2.9 (95% CI 2.12-4.06). The diagnosis of IED occurred earlier than most of the other mental disorders, except for those with usual onset in early childhood, as Specific and Social Phobias and Attention Deficit Disorder.

CONCLUSION: Considering that IED is a highly comorbid disorder and has an earlier onset than most other mental comorbidities in the Brazilian general population, these results may be useful in guiding governmental mental health actions.
