Objective : To investigate the willingness to receive HIV testing in primary health service institutions (PHSIs) among young students in Wuhan City, so as to provide the evidence for improving the detection of HIV testing among young students. Methods: Fifteen PHSIs were sampled using a stratified random sampling method in 14 districts of Wuhan City, and school students at ages of 15 to 24 years were sampled from each district using a convenience sampling method. Participants' demographics, awareness of AIDS-related knowledge, HIV testing and willingness to receive HIV testing were collected using questionnaires, and factors affecting the willingness to receive HIV testing in PHSIs were identified among school students using a multivariable logistic regression model. Results : A total of 301 questionnaires were allocated, and 299 valid questionnaires were recovered, with an effective recovery rate of 99.34%. The respondents included 143 men (47.83%) and 156 women (52.17%), and had a mean age of (19.36±2.40) years; there were 223 respondents with an educational level of diploma and above (74.58%). The awareness of AIDS-related knowledge was 71.57% among the respondents, and 144 respondents had received AIDS-related health education in PHSIs (48.16%). There were 34 respondents that had received HIV testing (11.37%) and 203 respondents that were willing to receive HIV testing in PHSIs (67.89%). The respondents that were unwilling to receive HIV testing in PHSIs were mainly attributed to considering to be unlikely to get HIV infections (82.29%). Multivariable logistic regression analysis showed that school students who knew AIDS-related knowledge (OR=2.797, 95%CI: 1.583-4.941), knew free HIV counseling and testing services in PHSIs (OR=2.070, 95%CI: 1.123-3.814), and had received AIDS-related health education in PHSIs (OR=2.814, 95%CI: 1.573-5.032) were more willing to receive HIV testing in PHSIs. Conclusions There were 67.89% of school students that were willing to receive HIV testing in PHSIs in Wuhan City, and the willingness to receive HIV testing was correlated with the awareness of risk of HIV infections, and awareness and experience of AIDS control services in PHSIs.
