摘要
目的分析甘肃省2011-2020年间新报告15~49岁和≥50岁HIV/AIDS的人群特征及新报告率变化趋势,为针对性地制定全省艾滋病防控措施提供参考依据。方法下载国家艾滋病防治基本信息系统2011-2020年甘肃省疫情资料,筛选出当年新报告15~49岁和≥50岁HIV/AIDS病例,对人群特征进行分析,用Joinpoint回归模型分析各年度新报告率的变化趋势。结果甘肃省2011-2020年新报告的HIV/AIDS中15~49岁病例所占构成比由90.57%下降至68.78%,≥50岁病例所占构成比由9.12%上升至31.13%;15~49岁和≥50岁病例男女性别比分别为7.49∶1和3.90∶1;≥50岁病例中初中及以下文化程度者占72.53%,农民占53.75%,异性传播占76.25%,样本来源于医疗机构占77.60%。15~49岁组男性和女性新报告率趋势变化不平行(P<0.05),转折点分别在2015年和2018年,男性病例2011-2015年、女性病例2011-2018年均呈现上升趋势,新报告率年度变化百分比分别为46.65%和15.23%。≥50岁组男性和女性新报告率趋势变化不平行(P<0.05),转折点均在2017年,男女病例2011-2017年均呈现上升趋势,新报告率年度变化百分比分别为49.92%和43.77%。结论甘肃省新报告HIV/AIDS病例以15~49岁为主,但≥50岁HIV/AIDS病例数增长很快,低文化程度者、农民是其主要的人群,医疗机构是主要的报告来源,异性性传播是主要的感染原因,2011-2020年15~49岁男女病例新报告率上升趋势有所减缓,但是≥50岁男女病例新报告率仍然呈现上升趋势,男性病例新报告率年度变化百分比最高,提示应关注该人群的艾滋病防治工作,有针对性地对该人群开展艾滋病宣传教育和行为干预等工作。
Objective To analyze the characteristics and Joinpoint trends in newly reported HIV/AIDS patients aged 15-49 and≥50 years in Gansu Province between 2011 and 2020 and to provide evidence for targeted prevention and control measures of AIDS in Gansu Province.Methods HIV/AIDS epidemic data of Gansu Province from 2011 to 2020 were downloaded from the National HIV/AIDS information system,and newly reported HIV/AIDS aged 15-49 and≥50 years were selected and analyzed.Joinpoint Regression Model was used to analyze the trend in the newly reported rates.Results The percentage of newly reported HIV/AIDS-positive individuals aged 15-49 dropped from 90.57%to 68.78%,while the percentage of newly reported HIV/AIDS cases aged≥50 increased from 9.12%to 31.13%.Male-to-female ratios in the 15-49 and≥50 age groups were 7.5∶1 and 3.9∶1,respectively.Among HIV/AIDS patients aged≥50,72.53%received education in junior high schools and below,53.75%were farmers,76.25%got infected by heterosexual route,and 77.60%were diagnosed with HIV/AIDS in hospitals.The changes in trend in the newly reported rates in males and females in the 15-49 age group were not parallel(P<0.05).The turning points were 2015 and 2018.The rates of male cases in 2011-2015 and female cases in 2011-2018 increased steadily,and annual percentage changes were 46.65%and 15.22%,respectively.The changes in trend for males and females in the≥50 age group were not parallel(P<0.05),the turning point was 2017.The rates in male and female cases in 2011-2017 increased rapidly,and annual percentage changes were 49.92%and 43.77%,respectively.Conclusion Among the newly-reported HIV/AIDS cases in Gansu,the majority is 15-49 years old.However,the number of HIV/AIDS cases≥50 years old increases rapidly.Moreover,low education levels and farmer profession are the main characteristics of the HIV/AIDS cases.Hospitals are the main source of HIH/AIDS diagnosis,and heterosexual transmission is the main cause of infection.The increasing trend of reported incidence in the 15-49 age group slows down after 2015,but the increasing trend in the≥50 years old group retains an upward tendency.The annual percent change in males is higher than that in females.The results imply that close attention should be paid to the healthcare of AIDS cases aged≥50 years old,and more targeted intervention should be delivered to these susceptible people.
