[Sexual behaviour and human immunodeficiency virus testing in university students from Cuzco (Peru)].

OBJECTIVE To analyse sexual behaviour, HIV testing, HIV testing intentions and reasons for not testing for HIV in university students from Cuzco (Peru). METHODS The sample comprised 1,377 university students from several institutions from Cuzco (Peru). The size of the sample was set according to a maximum 3% error estimation and a 97% confidence interval. Ages ranged from 16 to 30 years old. The data were collected through a self-administered, anonymous and voluntary questionnaire regarding sexual behaviour and HIV testing. The data were collected in classrooms during teaching hours. RESULTS A higher percentage of males than females reported having had vaginal, anal and oral sex, a higher number of sexual partners and an earlier age at first vaginal and oral sex. A higher percentage of females than males did not use condoms when they first had anal sex and had a higher anal sex-risk index. Most of the participants had never been HIV tested. The main reason was that they were sure that they were not HIV infected. CONCLUSIONS It seems that there was a low HIV risk perception in these participants despite the fact that they had been involved in sexual risk behaviours. Prevention campaigns focused on the general population as well as the at-risk populations and young people are needed.
