[BDSP. Notice produite par INIST iKb92R0x. Diffusion soumise à autorisation]. Background. Tuberculosis currently represents a serious problem in prison populations. Methods. With the aim of studying the predictive factors for, and the prevalence of, Mycobacterium tuberculosis infection and pulmonary tuberculosis in a Spanish prison, all those admitted during 1991 and 1992 were included (N=1314). The tuberculin skin test, HIV serology, chest X-ray and bacteriological examination of sputum were carried out. Statistical analysis was done by univariant tests, stratified analysis and logistic regression. Results. The prevalence of M. tuberculosis infection was 55.5% (95% confidence interval [CI] 52.5-58.5). An association was found with sex, imprisonment more than once, HIV infection and age. The co-infection rate (tuberculosis plus HIV) was 9.2%. Logistic regression showed a greater risk with age (4.4% per year), time spent in prison and for males. The prevalence of pulmonary tuberculosis was 1.26% and an association was found with M. tuberculosis infection, HIV infection (odds ratio [OR]=13.7), intravenous drug users (OR=17.2) and imprisonment more than once (OR=7.3). Logistic regression showed an association with HIV co-infection (OR=20.2). Conclusions. The prevalence of M. tuberculosis infection and pulmonary tuberculosis is high when compared with similar studies. The influence of age, time spent in prison and co-infection with HIV is relevant to recommendations for specific tuberculosis prevention programmes in correctional facilities.
