Women carrying human papillomavirus (HPV) run an elevated risk of preterm birth, a University of Gothenburg study shows. A connection can thus be seen between the virus itself and the risk for preterm birth that previously has been observed in pregnant women who have undergone treatment for abnormal cell changes due to HPV.
A Swedish study now published in the high-ranking journal
PLOS Medicine comprises data on more than a million births. Accordingly, the researchers have compared very large groups. They emphasize that the findings do not support any assessment of risk levels in individual women of childbearing age.
