Purpose:
To evaluate the percentage of intrauterine vertical human papillomavirus (HPV) transmission among HPV-positive mothers and the relative risk of intrauterine vertical HPV transmission between cesarean and vaginal delivery among HPV-positive women.
Methods:
This systematic review was made according to the PRISMA statement. We searched PubMed and Scopus and the final articles were selected by two reviewers. Data from the selected articles were plotted, and the pooled percentage of antenatal vertical HPV transmission among HPV-positive mothers as well as the pooled relative risk of antenatal vertical HPV transmission between cesarean and vaginal delivery among HPV-positive women were calculated.
Results:
9 studies including 421 HPV-positive mothers and their offsprings were selected from 434 potential papers. Following meta-analysis, the pooled percentage of antenatal vertical HPV transmission was 4.936% (95% CI 1.651-9.849), with moderate heterogeneity between the studies (I2 = 72.22%). The pooled relative risk of antenatal vertical HPV transmission between cesarean and vaginal delivery among HPV-positive women was 0.912, with no statistical significance (95% CI 0.226-3.674) and homogeneity between the studies (I2 = 24.48%).
