Abstract：Objective To analyze the basic characteristics of inquirers and human immunodeficiency virus(HIV)and syphilis infection status in the acquired immunodeficiency syndrome(AIDS)voluntary counseling and testing(VCT)clinics in Tianjin Nankai District Center for Disease Control and Prevention from 2013 to 2022,and to provide a scientific basis for formulating effective prevention and treatment measures for AIDS and sexually transmitted diseases(STD).Methods The general data and the test results of HIV antibody and syphilis antibody of the population receiving VCT in the AIDS VCT clinics in Tianjin Nankai District Center for Disease Control and Prevention from 2013 to 2022 were analyzed.Results From 2013 to 2022,the VCT clinics of Tianjin Nankai District Center for Disease Control and Prevention received a total of 3 853 counseling and testing individuals,including 3 333 males(86.50％),2 266 individuals aged 20-29 years(58.81％),2 644 unmarried individuals(68.62％),and 2 949 individuals(76.54％)with junior college diploma or above.The main reason for the inquiries was the history of non-commercial and non-fixed heterosexual sexual behavior in 1 814 individuals(47.08％).The positive rate of HIV antibody was 3.45％(133 cases),and the infection rate of syphilis was 1.40％(54 cases).Multivariate logistic regression analysis showed that male gender,age ≥50 years,high school education or secondary technical school education or below,history of non-commercial and non-fixed heterosexual sexual behavior,and syphilis infection were independent risk factors for HIV infection(P＜0.05),and age ≥50 years and HIV infection were independent risk factors for syphilis infection(P＜0.05).From 2013 to 2022,the infection rates of both HIV and syphilis showed fluctuating changes.Among them,the infection rate of HIV showed an upward trend from 2013 to 2019 and decreased significantly from 2019 to 2022[annual percent change(APC)=-61.49％,P=0.000 4],and the infection rate of syphilis increased significantly from 2013 to 2020(APC=68.82％,P=0.037),and decreased significantly from 2020 to 2022(APC=-94.26％,P=0.022).Conclusion The VCT clinic data from Tianjin Nankai District Center for Disease Control and Prevention from 2013 to 2022 show that the infection rates of HIV and syphilis are between the average levels in China and those in the high-incidence areas.The infection risk is relatively high among young people,the elderly and those with low educational attainment,and precise intervention needs to be strengthened.It is recommended to optimize testing strategies,strengthen publicity and education,pay attention to the needs of special groups,and establish a comprehensive prevention and treatment system in order to reduce infection risks and safeguard public health.
