Abstract

Human papillomavirus (HPV) infection contributes to most cases of cervical cancer, and HPV genotypes exhibit different distributions according to geographic region. This study evaluates the prevalence of HPV infection in Hetian Prefecture, Xinjiang, and establishes risk factors associated with high-risk HPV (HR-HPV) genotypes in this region. In this cross-sectional, population-based study, 883 healthy women 15-54 years of age were enrolled. All participants completed a questionnaire regarding sociocultural and sexual activity characteristics. Visual inspections with acetic acid, colposcopies and biopsies were performed using the Preventive Oncology International microbiopsy protocol for pathological diagnosis. Cervical epithelial tissue specimens were collected and tested for HPV using linear array assays. According to the results of HR-HPV infection status, individuals infected with HR-HPV were classified into one group, and the remaining individuals were classified into the control group. The risk factors for HR-HPF infection were analyzed. The participants included 66 women (7.47%) with HR-HPV, 10 women (1.13%) with low-risk HPV, and 14 women (1.59%) with HPV of unknown risk. The five most prevalent types of HR-HPV were HPV-16 (0.31%), HPV-51 (0.08%), HPV-31 (0.07%), HPV-58 (0.07%), and HPV-39 (0.06%). Vulvovaginal ulcers and vulvovaginal inflammation were found in 190 participants (21.52%) and 256 participants (28.99%), respectively. The HR-HPV and control groups significantly differed with respect to age at first marriage, number of marriages, and the presence of vulvovaginal ulcers and vulvovaginal inflammation (p<0.05). Based on this study, an immunization strategy targeting HPV-16 should be prioritized in Hetian Prefecture. These findings contribute to the understanding of HPV infection.
