Knowledge of HIV infection, risk perception, and sexual behaviour of undergraduates. May female medical students act as peer educators?

This paper is aimed to verify whether the knowledge and beliefs of female medical freshmen about HIV infection, their personal risk perception, and their sexual behaviour differs from their female peers, in view of the possibility of female medical student-based peer education. A purposive, theoretical quota sampling method was used to recruit the target population. A self-administered anonymous questionnaire was delivered to both female medical and non medical freshmen during March 2004 (n = 266: 124 medical students and 142 non medical students) in Catania (Sicily). The data were analysed for the whole sample and for the two groups of students individually. The Chi-square test was used to compare data from the two groups of students. Results showed that knowledge and risk perception about HIV infection were higher for medical students when compared with non medical students. Moreover, a lower rate of sexually active medical students and a higher rate of condom use was found among them. Since female medical students seem more sensitive to risk perception and aware of healthier lifestyles, they could be useful in peer sexual education and appropriate prevention programmes against HIV infection.
