Epidemiological study of human papillomavirus infection in 105,679 women in Wuhan, China

Abstract

Background Quality assessment of the prevalence and distribution of human papillomavirus (HPV) genotypes could support additional targeted HPV vaccinations. However, the characteristics of HPV infection in Wuhan city are limited in the past decade. We aimed to assess the epidemiology of HPV infection among women and provide a reference for the prevention and treatment of cervical cancer in this region. Methods A retrospective study employing 105,679 women attending Wuhan Medical and Health Center for Women and Children for cervical cancer screening from January 2015 to December 2022 was conducted. The HPV genotype was detected by polymerase chain reaction (PCR) and diversion hybridization. The overall incidence and age-specific type distribution of HPV infection and the relationship between HPV infection and cervical cytology were analyzed. Results The overall HPV infection rate was 16.87% in Wuhan city, and the prevalence rates of high-risk, low-risk and mixed high- and low-risk HPV infections were 13.64%, 1.77% and 1.46%, respectively. The five most prevalent genotypes were HPV52 (4.24%), HPV58 (2.42%), HPV16 (2.34%), HPV53 (1.87%), and HPV39 (1.66%). The prevalence of HPV in women exhibited a “two-peak” pattern, the peaks of which were observed in the < 21 years group (37.4%) and the 61–65 years group (41.72%). Logistic regression analysis revealed no significant difference in the rate of high-grade lesion positivity between single and multiple high-risk HPV infections. Among patients with a high-grade squamous intraepithelial lesion+ (HSIL+) ThinPrep cytologic test (TCT) diagnosis, HPV58 was the most common type, followed by HPV52, HPV16, HPV39 and HPV53. Conclusions HPV types 52, 58, 16, 53, and 39 were the most common types in the general female population in Wuhan, and the prevalence of HPV infection varied among different age groups. This study provides a comprehensive overview of the epidemiological characteristics of HPV infection in women, which could support the development of targeted prevention and control strategies for cervical cancer in the region.
