Abstract:
Objective:To understand the epidemiological characteristics and changing trends of HIV-infected patients aged ≥60 years reported in recent years in China and provide reference for the development of HIV prevention and control strategies for the elderly.Methods:The data of newly reported HIV-infected patients aged ≥60 years between 2015 and 2022 were obtained from China Information System for Disease Control and Prevention. The differences in epidemiological characteristics of HIV infections among groups were compared by using t test and Kruskal-Wallis H nonparametric test in software SPSS 24.0. Software Joinpoint 4.9.0 was used to calculate annual percent change (APC) and trend analysis was conducted by using Joinpoint regression model. Software Excel 2019 was used for graph drawing. Results:The number of reported HIV-infected patients aged ≥60 years in China increased from 17 451 in 2015 to 27 004 in 2022, with newly diagnosed rate rising from 9.0/100 000 to 10.2/100 000. The newly diagnosed rate in men was higher than that in women. Trend analysis demonstrated that the newly diagnosed rate in both elderly men and women peaked in 2019 (APC for men=13.5%, P=0.003; APC for women=15.0%, P=0.002), and showed a downward trend after 2019 (APC for men=-12.4%, P=0.006; APC for women=-13.0%, P=0.007). Among the elderly infected men, those infected by heterosexual and homosexual transmission accounted for 93.5% (160 747/171 924) and 5.1% (8 781/171 924), respectively. Among the elderly infected women, those infected by heterosexual transmission accounted for 98.4% (48 899/49 697). The infected elder people diagnosed by medical institutions accounted for 71.5% (158 394/221 621), whose baseline CD4 +T lymphocytes level was lower than that in those diagnosed by other ways ( H=1 079.82, P<0.001). Conclusions:The poor risk awareness and high-risk sexual behavior made the elderly at higher risk for HIV infection. More efforts should be made to improve active surveillance, timely detection and origin-tracing for infected elderly for the accurate and effective prevention and control of HIV infection.
