Abstract:
【Objective】 To obtain HTLV prevalence data among blood donors in mainland China through meta-analyze, and provide reference for relevant policies. 【Methods】 The literature concerning HTLV prevalence among blood donors in mainland China before April 15, 2021 in CNKI, Wanfang and Pubmed was searched. According to the inclusion criteria and exclusion criteria, relative literature within recent 10 years was screened and then analyzed by meta-analysis using R3.3. 【Results】 A total of 69 articles were included, covering 22 provincial administrative regions, with a total sample size of 7 435 501 cases. 535 cases were HTLV positive, of which 491 centred on three coastal provinces as Fujian, Guangdong and Zhejiang, and 44 scattered in 11 other provincial administrative regions. The pooled prevalence of HTLV in blood donors in Fujian, Guangdong and Zhejiang provinces were 3.25/10 000(95%CI 1.91/10 000~4.58/10 000), 0.13/10 000(95%CI 0.09/10 000~0.17/10 000) and 0.33/10 000(95%CI 0.06/10 000~0.61/10 000), respectively. Subgroup analysis showed that the pooled prevalence of HTLV in Fujian blood donors decreased since December 2015. 【Conclusion】 Blood donors in mainland China present low HTLV prevalence, mainly distributed in three coastal provinces as Fujian, Guangdong and Zhejiang. The sample size tested increased greatly since HTLV screening for blood donors was popularized nationwide in blood stations in December 2015, the infection rate of HTLV in Fujian, however, did not increase as expected.
