Human Papillomavirus DNA in Unselected Pregnant and Non-Pregnant Women

Abstract

Human papillomavirus (HPV) DNA is associated with genital squamous cell neoplasia, especially types 16, 18, and 31. Several studies, using histopathology and DNA hybridization, have shown an increased prevalence of cervical HPV DNA in pregnant women. We determined the prevalence of HPV DNA and the distribution of specific HPV DNA types in exfoliated cervical cells from 748 randomly selected pregnant and 503 non-pregnant women, using a dot blot DNA hybridization technique. The prevalence of HPV DNA was 9.6% in pregnant women and 8.9% in non-pregnant women. Thus, we found no evidence of higher prevalence of HPV DNA in pregnant women. HPV DNA types 16/18 and 31/33/35 were more common than types 6/11. The prevalence of HPV DNA was highest (15%) in the youngest age groups suggesting an association between young age and the prevalence of HPV DNA.
