ABSTRACT
The tuberculosis incidence rate in prisons in Rio de Janeiro State, Brazil, was 30 times higher in 2004 than in the general population and is probably underestimated, particularly given the difficult access to care in the prison setting. To obtain a better estimate, a survey used systematic X-ray screening and showed a prevalence rate of 4.6% in one such detention facility, A (n = 1,052). Two additional surveys, in facilities B (n = 590) and C (n = 1,372), showed even higher prevalence rates (6.3% and 8.6% respectively). A comparison of socio-demographic characteristics between A, B, and C showed a heterogeneous prison population. As compared to facility A, inmates in B and C come from poorer urban communities and have more frequent histories of incarceration and tuberculosis. These differences, consistent with the prevalence data, imply the necessary adaptation of tuberculosis control programs to each detention facility's epidemiological and socio-demographic profile.

Em 2004, a taxa de incidência da tuberculose nas prisões do Estado do Rio de Janeiro, Brasil, foi trinta vezes superior à da população geral do Estado. Essa taxa provavelmente é subestimada, especialmente pela dificuldade de acesso ao serviço de saúde nesse ambiente. Com o objetivo de melhor avaliar a situação, um primeiro inquérito radiológico sistemático foi realizado e mostrou taxa de prevalência de 4,6 por cento (prisão A, n = 1.052). Dois inquéritos adicionais revelaram, nas unidades B (n = 590) e C (n = 1.372), taxas maiores (6,3 por cento e 8,6 por cento, respectivamente). A comparação das características sócio-demográficas das prisões A, B e C mostrou que a população encarcerada não é homogênea. Em comparação com prisão A, os indivíduos encarcerados nas prisões B e C são oriundos de comunidades mais desfavorecidas e têm mais freqüentemente história de encarceramento anterior e de tuberculose. Essas diferenças, coerentes com os dados de prevalência, implicam a adaptação das medidas de controle da tuberculose ao perfil epidemiológico e sócio-demográfico de cada unidade prisional.
