HIV screening results of college group blood donors in Tianjin from 2012 to 2021 / 中国输血杂志

ABSTRACT

【Objective】 To analyze the infection characteristics and prevalence of HIV among college group voluntary blood donors in Tianjin, China, so as to provide data support for improving the promotion and recruitment strategies of voluntary blood donors, ensuring the safety of blood for clinical use, and formulating HIV prevention and control strategies for adolescents. 【Methods】 The college donors with anti-HIV(+ ) and HIV RNA(+ ) results in Tianjin from January 1, 2012 to December 31, 2021 were selected and analyzed. The relationships among HIV positive rate(anti-HIV+ or HIV RNA+ ), solo anti-HIV positive rate(anti -HIV+ and HIV RNA-), solo HIV RNApositive rate(anti-HIV- and HIV RNA+ ) and double positive rate(anti-HIV+ and HIV RNA+ ) between different years, gender, residence status, age and blood donation history(primary or repeated blood donation) were counted. 【Results】 The HIV positive rate and solo HIV RNA positive rate of college group blood donors from 2012 to 2021 showed a trend with significant increasing(χ2=49.266, 71.379, P<0.05). The HIV positive rate in the controls was significantly higher than that in the college blood donors(χ2=92.414, P< 0.05). The HIV positive rate and solo anti-HIV positive rate showed no differences by genders, but the male presented significant higher positive rate in solo HIV RNA and double positive results than the females(χ2=6.059, 10.900, P<0.05). The HIV positive rate of local resident was significantly lower than those nonlocal students(χ2=47.523, P<0.05). The HIV positive rate differed significantly by ages, with the highest at the age of 18 and the lowest at the age of 21(P<0.05). The difference of HIV double positive rates between the first-time and repeated donors was marginal, while the other three positive rates in thefirst-time donors were significantly higher than those in the repeated donors (P<0.05). 【Conclusion】 In recent years, the HIV positive rate and solo HIV RNA positive rate of college group blood donors present an increasing tendency. The consultation and education on HIV-related issues should be strengthened among college students during blood donation publicity, so as to ensure the safety of blood use and prevent the spread of AIDS in schools.
