Objective To describe sexually transmitted infections among human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in Xiaoshan district of Hangzhou city for theidentification of key popula-tions in surveillance and to provide evidences for developing effective prevention and control measures.
Methods We collected personal profiles and follow-up data on 603 sexually infected HIV/AIDS patients newly diagnosed from 2013 through 2017 and registered at Xiaoshan District Center for Disease Control and Prevention. Differences in demographics, high-risk behaviors, social support, and prevention and treatment measures among the patients were analyzed using chi square test and multivariate logistic regression model.
Results For the patients included, homosexual transmission became a predominant infection route since 2014. There were significant differences in the sex, age, education, marital status and occupation between the patients with homosexual and heterosexual transmission. The homosexual transmission mainly occurred in unmarried men aged 20 to 39 years, while heterosexual transmission mainly occurred in married men over 40 years old. The main high-risk behavior of homosexual transmission was male-male sex and that of heterosexual transmission was unfixed sexual partner. Multivariate logistic regression analysis revealed that there were significant differences in the extramarital commercial and non-commercial heterosexual behaviors, sex with unfixed sexual partners, and venereal history between patients with homosexual and heterosexual transmission. Most (96.7%) of the patients received health education and counselling, while a few of them received medication (0.5%) and care assistance (3.5%). The tuberculosis detection rate and antiviral treatment rate in the patients were 61.0% and 84.2% respectively.
Conclusion Among sexually infected HIV/AIDS patients, homosexual transmission became a predominant route of HIV infection; the demographics and high-risk behaviors are different between the patients with different ways of sexual transmission. The social support available to the HIV/AIDS patients is inadequate and the patients are more passive in receiving prevention and control interventions.
