Abstract: Objective To understand the willingness to accept peer HIV voluntary counseling and testing (VCT) among college students in Guangzhou and its influencing factors,and to provide reference for controlling and preventing of AIDS on compus.Methods A self-designed study was conducted among 3 079 undergraduates selected from 12 colleges between October and December,2016 by convenience sampling method.Chi-square test and multi-factor Logistic regression were adopted to identify independent correlates that were associated with willingness to take peer VCT.Results About 90.8%(2 795) would like to provide peer VCT when in need of VCT.According to regression analysis,compared to attitude of accepting peer VCT and indifference to VCT,male students(OR =1.548),majoring in science and engineering(OR =1.324),unsure of sexual orientation(OR =1.755),having no information about epedemic situation(OR=1.738),not worrying about being infected with HIV(OR=1.589),not accepting the peer education (OR=1.649) and moblizing to accept VCT (OR =1.655) tended to be indifferent(P<0.05).Compared to accepting VCT,male(OR =1.514),not worrying about their HIV infection(OR =1.358),not receiving peer education (OR =1.954) and abusing drug while having sexual activity were likely to not accept peer VCT(P<0.05).Conclusion The high acceptability of peer VCT among students can serve as a complementary method for scaling up HIV test in Guangzhou.This tailored VCT service can increase testing willingness for female students who concern on health.
