  1. Brazilian multicentric study of psychiatric morbidity : Methodological features and prevalence estimates.

    Article - En anglais

    Background Psychiatric morbidity studies in developing countries have used diagnostic procedures of low reliability, without a clinical definition ofcaseness, producing descriptive data with limited application for mental health planning.

    Method Atwo-stage cross-sectional design (with a sample size of 6476) was conducted to estimate the prevalence of DSM-III psychiatric diagnoses in three metropolitan areas of Brazil (Brasilia, Sao Paulo and Porto Alegre).

    All subjects were screened for the presence of psychopathology with a 44-item instrument (the QMPA) and a subsample was selected for a psychiatric interview.

    Results Age-adjusted prevalence of cases potentially in need ofcare ranged from 19% (Sao Paulo) to 34% (Brasilia and Porto Alegre).

    Anxiety disorders comprised the highest prevalences (up to 18%). Alcoholism yielded the most consistent prevalence levels, around 8% in all sites.

    Depression showed great variation between areas : from less than 3% (Sao Paulo and Brasilia) to 10% (Porto Alegre).

    Conclusions Overall prevalences were high in comparison with previous studies conducted in Brazil.

    A female excess of non-psychotic disorders (anxiety, phobias, somatisation and depression) and a male excess for alcoholism were consistently found.
