Abstract Background To analyze the trends of HIV-1 and syphilis prevalence as well as associated factors among local Chinese female sex workers (LCFSWs) and cross-border migrant female sex workers (CMFSWs) in Sino-Vietnam border cities in Guangxi, China. Methods A consecutive cross-sectional study was conducted from 2010 to 2018 in three border cities in Guangxi. The survey was conducted through face-to-face interview with a structured questionnaire. HIV-1 and syphilis infections were tested simultaneously. Cochran-Armitage analysis was used to assess the trends of HIV-1, syphilis and HCV prevalence, as well as the trend of risk behaviors, HIV/AIDS knowledge and prevention services. Multivariate logistics regression analysis was used to identify factors associated with HIV-1 and syphilis infection. Results Totally, 19873 LCFSWs and 1723 CMFSWs were enrolled. The overall prevalence of HIV-1 and syphilis infection was 0.91% and 5.14%, respectively. The HIV-1 prevalence among CMFSWs was higher than that among LCFSWs, without a declined trend. However, a downward trend was observed among LCFSWs. Overall, the main associated factors of HIV-1 infection among CMFSWs shifted from age >35 years old, staying in current residence for >12 months, self-reporting sexually transmitted infections (STIs) in the last year during 2010-2015 to inconsistent condoms use in commercial sex in last month, not receiving peer education and self-reporting STIs in the last year during 2016-2018.
