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