The consultation for PEP services and the related factors of college students who were at high risk for HIV infection were analyzed.

Results

The proportion assessed as being at high risk for HIV infection was 43.47% (996/2 291), and the proportion of consultation for PEP services was 9.24% (92/996). Multivariate logistic regression analysis showed that among college students who were at high risk for HIV infection, the positive related factors of consultation for PEP services included knowing about PEP services (aOR=17.49, 95%CI: 7.98-38.36) ,having HIV tests (aOR=3.92, 95%CI: 2.08-7.42) and access to condoms on campus (aOR=3.38, 95%CI: 2.02-5.65), and the negative related factor was homosexual orientation (aOR=0.24, 95%CI: 0.06-0.91).

Conclusions
