Characteristics and spatiotemporal distribution analysis of reported HIV/AIDS aged ≥50 infected through commercial heterosexual behavior in Chongqing from 2015 to 2023
Objective To analyze the characteristics and spatiotemporal distribution of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) cases among individuals aged ≥50 infected through commercial heterosexual behavior in Chongqing, and to provide scientific references for HIV/AIDS prevention and control among the elderly population.Methods The reported HIV/AIDS cases aged≥50 from 2015 to 2023 with a history of commercial heterosexual behavior were analyzed. SPSS 23.0 software was used for descriptive epidemiological, and ArcGIS 10.6 software was used for spatial analysis.Results From 2015 to 2023, Chongqing reported 16 096 HIV/AIDS aged ≥50 and infected through commercial heterosexual behavior, accounting for 72.3% of all HIV/AIDS infected through commercial heterosexual behavior, and the proportion showed an increasing trend (χ2trend=631.208, P < 0.001). The cases were predominantly male (94.7%), married (59.0%), aged 50- < 70 years (68.9%), farmers (62.1%), and with primary school education or below (71.1%). The majority of cases were distributed in the central urban areas and main urban districts (82.7%), primarily detected through medical institutions (70.2%), with 68.8% having initial CD4+ T cell counts < 350 cells/μL. Spatial analysis indicated that the cases were clustered and centered around Yongchuan District, Dazu District and Rongchang District spreading to surrounding districts.Conclusions The proportion of HIV/AIDS cases aged ≥50 infected though commercial heterosexual behavior in Chongqing has been increasing annually, and the distribution of cases is clustered. Comprehensive intervention measures should target commercial heterosexual behavior.
