Abstract: Objective To understand the willingness and influencing factors of HIV testing among secondary vocational school students in Guangzhou, and to provide a basis for targeted measures to improve their HIV testing awareness and action ability. Methods In October 2020, a stratified cluster sampling method was used to select students from four secondary vocational schools in Guangzhou, and an on-site questionnaire survey was conducted on their willingness to undergo HIV testing and its influencing factors. The Chi-square test was used for univariate analysis, and unconditional binary logistic regression was used for multivariate analysis. Results The average age of 1 864 secondary vocational school students participating in the survey was （16.27 ± 1.20） years old, and the male to female ratio was 1∶2.43. The awareness rate of AIDS prevention and control knowledge was 52.90% （986/1 864）. The incidence of reported sexual behavior was 5.63% （105/1 864）. The HIV testing rate of students who had sex was 14.29% （15/105）, and 73.28% （1 366） were willing to get HIV testing after risky sex. Multivariate logistic regression analysis showed that the place of origin of students （OR=0.661）, AIDS awareness （OR=0.445）, correct sexual attitudes and behaviors （OR=1.591）, whether they have heard of HIV testing （OR=0.446）, and whether they have received publicity and education on AIDS prevention and control （OR=0.538, 0.648） were the main factors affecting the willingness of secondary vocational school students to HIV testing. Conclusions Secondary vocational school students in Guangzhou have a higher willingness to undergo HIV testing, but students who engage in sexual activity have a lower testing rate. Rural students have a lower willingness to undergo testing. Therefore, it is necessary to strengthen education on students' correct sexual attitudes and testing related knowledge and policies, and to invest educational resources in rural areas in a more favorable manner.
