Does knowledge about sexually transmitted infections increase the likelihood of consistent condom use?

Background. We aimed to assess the association between knowledge about sexually transmitted infections (STIs) and consistent condom use among university students controlling for selected socio-demographic factors. Method. An anonymous questionnaire survey was carried out among 720 undergraduate students (76% women) at the University of Tirana, Albania, in October–November 2002. The questionnaire included socio-demographic data, 10 multiple-choice test questions on knowledge about STIs, sexual activity and use of condoms. Two hundred seventy-nine students reported having sexual experience and provided data on condom use as well as knowledge about STIs. Binary logistic regression was used to assess the “independent” association between knowledge about STIs and condom use. Results. In multivariable models, there was an overall association of knowledge about STIs with consistent condom use (OR = 1.74, 95% CI = 1.37–2.23, P < 0.001). There was evidence for an interaction between knowledge and parental education (P = 0.04): there was a positive association among students with highly educated parents (OR = 1.48, 95% CI = 1.11–1.99, P = 0.01), and particularly so among students with low-and-middle educated parents (OR = 4.75, 95% CI = 2.03–11.08, P < 0.01). Conclusions. Knowledge about STIs is an independent predictor of consistent condom use among university students. Augmentation of knowledge per se should be a component of school-based prevention programs along with the intensification of efforts toward improving studentsʹ sexual practices.
