Abstract:
Objective To analyze the basic characteristics and diagnosis trends of newly reported HIV/AIDS cases in Guizhou province from 2012 to 2023 and provide evidence for the development of AIDS prevention and control measures.
Methods The data of newly reported HIV/AIDS cases in Guizhou from 2012 to 2023 were collected from National Health and Disease Control Information System for a descriptive analysis on the distributions of the HIV/AIDS cases, and the diagnosis trends were analyzed by using Joinpoint regression model.
Results A total of 86176 HIV/AIDS cases were reported in Guizhou from 2012 to 2023. The male to female ratio of the cases was 2.22∶1. The average age of the cases was (48.46±16.55) years and the cases caused by sexual transmission accounted for 97.27%. The cases were mainly reported by medical institutions, accounting for 72.81%. The diagnosis rate showed an increasing trend from 2012 to 2023 average annual percentage changes (AAPC) =7.86%, P<0.001, increased rapidly from 2012 to 2018 annual percentage changes (APC) =18.75%, P<0.001, and slowly decreased from 2018 to 2023 (APC=−3.90%, P=0.016). The diagnosis rates in both men and women were similar to the overall rate. The diagnosis rate showed a monotonical decreasing trend in age group 0−<15 years (APC=−3.91%, P=0.029). The diagnosis rate showed a rapid increase from 2012 to 2018 (APC=16.38, P<0.001) and showed a monotonical decreasing trend after 2018 (APC=−4.19%, P< 0.001) in age group 15−<65 years. The diagnosis rates showed a rapid increasing trend in age group ≥65 yearsfrom 2012 to 2018 (APC=42.94%, P<0.001) and the change after 2018 was not significant. Except northern Guizhou (APC=−2.47%, P=0.183), the diagnosis rates showed a slow downward trend in other areas in Guizhou after 2018. The proportion of newly reported HIV/AIDS cases with the first CD4+T count <200/μL showed a monotonical increasing trend (APC=4.91%, P<0.001), but the proportion of newly reported HIV/AIDS cases with the first CD4+T count 350−499/μL (APC=−3.21%, P<0.001), ≥500/μL (APC=−6.22%, P=0.012) showed slow decreasing trends.
Conclusion From 2012 to 2023, the overall increase of the newly reported HIV/AIDS cases became slow in Guizhou, but the cases in northern Guizhou and in age group ≥65 years still showed no decrease. Most HIV/AIDS cases had later detections. The prevention and treatment measures should be improved according to the age and area specific distributions of HIV/AIDS casesfor the the early case detection.
