Trends in condom use and risk behaviours after sexual exposure to HIV: a seven-year observational study.
Abstract
ObjectiveWe aimed to determine the trends in numbers and percentages of sexually exposed persons to HIV (SE) consulting an ED for post-exposure prophylaxis (PEP), as well as predictors of condom use.Study designWe conducted a prospective-observational study.MethodsWe included all SE attendances in our Emergency Department (ED) during a seven-year study-period (2006-2012). Trends were analyzed using time-series analysis. Logistic Regression was used to define indicators of condom use.ResultsWe enrolled 1851 SE: 45.7% reported intercourse without condom-use and 12.2% with an HIV-infected partner. Significant (p0.05), in MSM +228% (pConclusionWe report an increasing trend in the number of SE, mainly among MSM, and rising trends in high-risk behaviours and unprotected sexual intercourses among MSM. Our results indicate that SE should be considered as a high-risk population for HIV and sexually transmitted diseases.
