Epidemiological characteristics of newly reported HIV/AIDS cases in Shanxi based on Joinpoint regression model,2013-2022
Objective To understand the epidemiological characteristics and trends of newly reported human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS)cases in Shanxi province during 2013-2022 and provide theoretical evidence for the prevention and control of AIDS.Methods The information of newly reported HIV/AIDS cases in Shanxi from 2013 to 2022 were downloaded from the National Health Security and Disease Control Information System,and the characteristics of the newly reported HIV/AIDS cases were statistically described and analyzed,and the trends were analyzed by using Joinpoint regression model.Results A total of 12 983new HIV/AIDS cases were reported in Shanxi from 2013 to 2022.The cases were mainly caused by sexual transmission,the male to female ratio of the cases was 6.19∶1(11 178∶1 805),and the average age of the cases was(39.65±14.49)years.The cases were mainly reported by medical institutions.The trend analysis showed that the newly reported HIV/AIDS cases from 2013 to 2022 in Shanxi showed a slight increasing(AAPC=5.82％,P=0.008).In the age group＞50 years,the cases showed an increasing trend in men(AAPC=8.94％,P=0.001),and an increasing trend by year in women(APC=10.05％,P=0.001).In sexual transmission,the heterosexual transmission and homosexual transmission all decreased in age group 0-24 years(APC=-12.13％,P＜0.001;APC=-6.87％,P＜0.001),but the heterosexual transmission and homosexual transmission all increased in age group＞50 years(APC=7.26％,P＜0.001;APC=16.70％,P＜0.001).The area specific trend of new detection rate was inconsistent;and the proportion of newly reported cases with the first CD4 cell count＜200/μL showed a slight increasing trend by year(APC=3.94％,P＜0.001)Conclusion From 2013 to 2022,newly reported HIV/AIDS cases showed an increasing trend in Shanxi.More cases aged＞50 years were reported and more cases were not detected in a timely manner.It is suggested to pay close attention to the elderly,take precise intervention measures and expand the coverage of AIDS screening to effectively curb the spread of AIDS.
