AVALIAÇÃO DA SOROPREVALÊNCIA E DOS FATORES DE RISCO DE INFECÇÃO POR SÍFILIS EM INDIVÍDUOS PRIVADOS DE LIBERDADE DO COMPLEXO PRISIONAL DE APARECIDA DE GOIÂNIA.

Abstract

Background: Syphilis is an infectious disease that in Brazilian prison systems has optimal conditions to increase the risk of transmission among inmates. Objectives: Determine prevalence and assess risk situations associated with transmission of syphilis among inmates of Prison Complex Aparecida de Goiânia/GO in the period from February to September 2011. Methods: cross-sectional study exploratory of quantitative approach. Study participants were 1.173 inmates that answered a questionnaire containing variables on behaviors risk for T. pallidum infection. The seroprevalence was found using serological tests screening VDRL and ELISA as confirmatory. Data were tabulated and the variables were analyzed using the EPI INFO and SPSS (Statistical Package for Social Sciences).Were calculated rates of seroprevalence by age and educational level, and relative risks (odds ratios) associated with risk behaviors. Results: The seroprevalence of syphilis found in this population was 2.22% (IC95%). Of the study participant s total, 83.4% were aged between 18 and 39 years. This age group contributes with 85% of cases found positive for serological screening. The seroprevalence among those with low education contributed 58.2% of the population seroprevalence. For the variables of risk situations the homosexual relationship had an odds ratio of 3.44 (IC 0,77 - 15,29 and p=0,084), use of tattoo 3.05 (IC 1,14 - 8,14 and p=0,019), condom use 1.84 (IC 0,40 - 8,43 and p=0,356)and use of injecting drugs 3.71 (IC 1,35 - 10,13 and p=0,006).Conclusions: The seroprevalence rate was lower than those found in studies performed in other prisons in the country. Of the variables evaluated in the study the use of tattoos and the use of injectable drugs were statistically significant risk factors associated with seropositivity to syphilis. The combination of risk situations evaluated in this study can contribute to the transmission of syphilis on the Brazilian prisons.
