We determined the prevalence of sexually transmitted infections (STIs), the factors associated with infection and types of counseling received by men and women from health professionals in the City of S?o Paulo.

Protective factors included not having had sexual intercourse with someone from the same sex, among men, and having initiated sexual activity after the age of 15 years and not having a casual sex partner over the last 12 months, among women. Counseling about the importance of HIV and syphilis testing was received by 72.1% and 64.7% of women, respectively, while fewer than half of the men received this type of counseling (40.2% and 38.6 %, respectively). The prevalence of previous history of a STI was high among the population of the City of S?o Paulo. The findings of this study informed the development, implementation, and evaluation of STI policies, including those directed at HIV, leading to a reduction in the barriers that hinder access to and use of condoms and the creation of STI prevention app .
