Objective To explore the service utilization and effectiveness of preventing mother-to-child transmission(MTCT)for HIV-infected women among the floating population in Nanning City.Methods A total of 1 276 pregnant women with HIV infection were divided into the floating population group and the non-floating population group according to their household registration from 2010 to 2021 in Nanning City.The case data of these populations and their offspring were collected and further analyzed using a chi-square test and logistic regression model to investigate their characteristic distribution,service utilization,and effectiveness of MTCT prevention,as well as their influencing factors.Results From 2010 to 2021,647 cases of pregnant women with HIV infection were identified among the floating population in Nanning,constituting 50.71％of the total.The infection,mortality,and MTCT rates among children born to HIV-infected mothers(HIV-exposed children)in the floating population were 1.43％,2.78％,and 2.48％,respectively.Multivariate analysis showed that,compared to HIV-infected women in the non-floating population,HIV-infected women in the floating population were less likely to receive prenatal examinations in the first trimester(OR=0.690,95％CI:0.547-0.872)and to perform viral load test during pregnancy(OR=0.604,95％CI:0.417-0.874).Moreover,compared to HIV-exposed children in the non-floating population,HIV-exposed children in the floating population were less likely to receive one HIV antibody test(OR=0.669,95％CI:0.508-0.881),two or more HIV antibody tests(OR=0.727,95％CI:0.578-0.914),and six or more follow-up visits(OR=0.781,95％CI:0.623-0.979),while the risk of being lost to follow-up was higher(OR=1.601,95％CI:1.095-2.340).Conclusions Population mobility affects the prenatal examination of HIV-infected women and their children's follow-up visits.Thus,it is necessary to strengthen the management of the floating population with HIV infection.
