Factors associated with non-use of condoms and prevalence of HIV, viral hepatitis B and C and syphilis: a cross-sectional study in rural communities in Ouro Preto, Minas Gerais, Brazil, 2014-2016.

OBJECTIVE

to investigate socio-demographic factors associated with non-use of condoms, and to describe the prevalence of sexually transmitted infections (STI) in rural communities of Ouro Preto, Minas Gerais, Brazil, 2014 to 2016.

METHODS

data were gathered from individual interviews and rapid tests were performed; associations were tested using Poisson regression, with a 95% confidence interval (95%CI).

RESULTS

we detected 3.8 cases/10,000 inhabitants for hepatitis B and syphilis, and 1.3 cases/10,000 inhabitants for hepatitis C; no HIV cases were detected; in the multivariate analysis we found higher prevalence rates of condom non-use among the group of individuals who were married, had common law partners or were widowed (PR=1.20 - 95%CI 1.06;1.36).

CONCLUSION

individuals in a stable relationship formed the group with the highest prevalence rate of condom non-use; new syphilis and viral hepatitis cases were detected using rapid tests during the survey.
