Psychiatric disorder and the use of benzodiazepines: an example of the inverse care law from Brazil

Soc Psychiatry Psychiatr Epidemiol. 1999 Jun;34(6):316-22. doi: 10.1007/s001270050150.

Abstract

Background: A cross-sectional survey was conducted in Pelotas, southern Brazil, to assess the relationship between the use of benzodiazepines (BZD), minor psychiatric disorders (MPD) and social factors.

Methods: A representative sample (n = 1277) was interviewed using the Self-Reporting Questionnaire (SRQ-20) for MPD. Subjects were asked about the use of BZD in the preceding 2 weeks and were also asked for socioeconomic details.

Results: A total of 152 (11.9%; 95% CI 10.1-13.7) subjects had taken psychotropic drugs, with BZD being the most commonly reported (8%). The prevalence of MPD was 22.7% (95% CI 20.4-25.0): males 17.9% and females 26.5%. An inverse relationship was seen between level of income, schooling and prevalence of MPD (P < 0.001), but a positive relationship was found between income and BZD consumption (P < 0.05).

Conclusions: These data suggest that the inverse care law operates in prescribing psychotropic medications for MPD.
