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.
