目的 分析不同孕期乙型肝炎病毒宫内感染率的差异 ,探索 HBV宫内感染发生的时间 .方法 运用 Meta分析技术对 9个不同孕期 HBV母胎传播发生率研究进行定量综合分析 .结果 孕早期的宫内感染率最低 (0 .4 8% ) ,而孕晚期的感染率 (14 .0 7% )高于孕中期 (4.33% ) (d=0 .10 4 9,95 .0 0 % CI=0 .0 5 2 - 0 .15 8) .对各研究结果做齐性检验 ,未见显著差异 (P>0 .0 5 ) .结论 HBV宫内感染可发生在孕期的各个阶段 ,但主要的发生时间是孕晚期 .
Objective To analyze the difference of intrauterine infection rates of Hepatitis B virus in different gestation periods and to explore the time of intrauterine HBV infection.Methods Meta analysis was used to analyze the incidence of HBV maternal birth in 9 different pregnancies.Results The infection rate in the third trimester (14.07%) was higher than that in the second trimester (4.33%) (d = 0.10 4 9,95 .0 0% CI = 0 .0 5 2 - 0. 15 8) .There was no significant difference (P> 0.05) between the results of all the tests.Conclusion HBV intrauterine infection can occur in all stages of pregnancy, but the main occurrence Time is third trimester.
