Objective To understand the epidemiological characteristics and trends of newly reported HIV/AIDS individuals in Daxing District,Beijing from 2009 to 2023,and to provide evidence for better formulation of AIDS prevention and control strategies. Methods Newly reported HIV/AIDS individuals were recruited with current living addresses in Daxing District from 2009 to 2023.Excel 2021 software was used to set up the database and SPSS 26.0 was employed for data processing and analysis.Joinpoint software was used to construct linear regression models to explore the prevalence trends. Results From 2009 to 2023,the annual reported HIV/AIDS cases in Daxing District showed an increasing trend (2009-2016) followed by a decreasing trend (2016-2023).Totally,2 060 individuals were newly reported,including 1 643 HIV infections and 417 AIDS patients.The reported cases were primarily characterized by non-Beijing household registration (59.1%),male (94.7%),age at 20-49 group (85.0%),unmarried status (56.6%),college education or higher (47.9%),and engagement in housework,domestic work,or non-engagement in work (42.7%).Sexual contact accounted for 95.8% of infections,with 74.6% of men who had sex with men (MSM).The source of cases was mainly testing and counseling (29.7%) and the median CD4+ T cell count was 361.0 cells/mL(233.0,496.0). Conclusion The HIV/AIDS epidemic in Daxing District showed an upward and then downward trends.and it is mainly transmitted through MSM.The knowledge of HIV/AIDS prevention and control should be reinforced focusing on the high-risk groups,effective intervention and control measures should be taken,and AIDS prevention and control efforts should be strengthened for mobile populations and the elderly.
