目的了解玉溪市≥50岁人群艾滋病病毒感染者/艾滋病病人(HIV/AIDS)病例占总报告数比的上升原因,对其疫情做较全面分析。方法通过问卷调查、HIV阳性检出率、新近感染状况、首次CD4~+T淋巴细胞计数<200情况对本院≥50岁人群疫情进行综合分析。结果问卷调查显示≥50岁人群艾滋病知识知晓较比较组低(P<0.001),且较少获得相关宣传,但其主要通过医院途径获取艾滋病检测且有更多机会获得检测(P<0.001);2010-2013年玉溪市人民医院90 778例住院及手术病人阳性检出率为0.59%,其中≥50岁组与比较组阳性检出率分别为0.41%和0.68%,近年≥50岁组检出率并未出现上升趋势(P=0.121)而比较组却出现上升趋势(P<0.001);2007-2013年35.80%新报告≥50岁人群感染者首次CD4~+T淋巴细胞计数小于200,18.96%新报告比较组感染者首次CD4~+T淋巴细胞计数小于200,差异有统计学意义(P=0.001)。结论玉溪市≥50岁人群艾滋病知晓率低,但是有更多机会通过医院获得艾滋病检测;阳性检出率较低且近年无上升趋势;新近感染比例及首次CD4~+T淋巴细胞计数结果显示其可能多年前就已经感染而近年才通过扩大检测发现,需持续追踪调查≥50岁人群艾滋病疫情。
Objective To understand the reasons why the number of people living with HIV / AIDS (HIV / AIDS) in the population aged≥50 years in Yuxi City had risen from the total number of reports and make a comprehensive analysis of the epidemic situation. Methods A comprehensive analysis of the epidemic situation of the population over 50 years of age in our hospital was conducted by means of questionnaire, HIV positive detection rate, recent infection status, first CD4 ~ + T lymphocyte count <200. Results The questionnaire survey showed that AIDS knowledge of people over 50 years old was lower than that of the comparative group (P <0.001), and less publicity was obtained. However, HIV / AIDS knowledge was obtained mainly through hospitals and had more chance of being tested (P <0.001). The positive rate of 90 778 hospitalized and operative patients in Yuxi People’s Hospital during 2010-2013 was 0.59%, of which the positive rates were 0.41% and 0.68% in ≥50 years old group and 0.68% (P = 0.121), while the comparison group showed an upward trend (P <0.001). The first CD4 ~ + T lymphocyte count in 35.80% of newly reported persons ≥50 years old in 2007-2013 was less than 200 and 18.96 % The new report compared the first CD4 ~ + T lymphocyte count less than 200, the difference was statistically significant (P = 0.001). Conclusion There is a low awareness rate of AIDS among people over 50 years of age in Yuxi City, but more chances of getting AIDS through hospitals are obtained. The positive detection rate is low and there is no upward trend in recent years. The recent infection rate and the first CD4 ~ + T lymphocyte count show It may have been infected many years ago and in recent years it was discovered through the expansion of testing that it is necessary to continuously follow up the epidemic of AIDS in people over 50 years of age.
