ABSTRACT
Objective@#To analyze current situation of HIV/AIDS case detection and factors associated with late diagnosis among the newly diagnosed cases from 2013 to 2018 in Hangzhou, so as to provide basis for improving the detection capacity of HIV. @*Methods@#The data of HIV testing and newly diagnosed HIV/AIDS cases in Hangzhou from 2013 to 2018 were collected through the China AIDS Prevention and Control Information System. The proportion of HIV antibody detection and positive cases in different regions, detection ways and high-risk groups were analyzed. The influencing factors for late diagnosis were analyzed by multivariate logistic regression model. @*Results@#The proportions of cases with HIV detected, HIV positive and late diagnosis increased from 2013 to 2018, and the annual ones were 24.99%, 6.95 per ten thousand and 30.07%, respectively. The results of the multivariate logistic regression analysis showed that people who were male ( OR=1.656, 95%CI: 1.351-2.030 ) and aged older ( OR: 1.912-5.117, 95%CI: 1.250-7.904 ) had higher risks of late diagnosis; who detected HIV through pre-test of receiving blood ( OR=4.429, 95%CI:2.217-9.225 ) , other inpatient detection ( OR=2.137, 95%CI: 1.615-2.826 ) , preoperative testing ( OR=2.137, 95%CI: 1.615-2.826 ) and testing of STD clinic attendants ( OR=1.359, 95%CI: 1.007-1.834 ) had higher risks of late diagnosis compared to those diagnosed at VCT clinics; who diagnosed at CDCs ( OR=0.714,95%CI: 0.558-0.915 ) and community health centers ( OR=0.645, 95%CI: 0.441-0.943 ) had lower risks of late diagnosis than those diagnosed in hospitals; who were infected by heterosexual contact ( OR=1.299, 95%CI: 1.130-1.493 ) had a higher risk of late diagnosis than MSM; who had history of STD ( OR=0.818, 95%CI: 0.706-0.948 ) had a lower risk of late diagnosis than who did not.@*Conclusions@# HIV testing and case detection had been expanded, but late diagnosis had not been improved in Hangzhou from 2013 to 2018. Age, sex, route and institution of diagnosis, transmission route and history of STD were influencing factors of late diagnosis.
