    Abstract:
    OBJECTIVE: This study aimed to investigate the prevalence characteristics of human papillomavirus (HPV) infections in 29,508 female cases in Jinshan District, Shanghai. MATERIALS AND METHODS: The current research represents a retrospective study that included 29,508 women who received cervical screening in the Jinshan Branch of Shanghai Sixth People's Hospital from 2010 to 2020. The overall prevalence, distribution types, age-specific prevalence and annual trends were analysed. RESULTS: The overall HPV infection rate among the patients was 21.97%. They were primarily high-risk HPV (HR-HPV) infections (20.30%) and single HPV infections (15.91%). A general decline in HPV and HR-HPV prevalence was observed with time from 33.52% to 25.45% in 2011 to 21.47% and 20.18% in 2020. The most common HPV genotypes were HPV52, HPV16, HPV58, HPV51, HPV53 and HPV68. The infection rates of HPV genotypes, including HPV6, HPV11, HPV16, HPV18, HPV31, HPV33, HPV35, HPV39, HPV42, HPV43, HPV66 and HPV68, showed overall declines across different years. The age-specific prevalence of total HPV and HR-HPV infections formed an approximate U-shaped curve with two peaks, one in the ≥55 age group (29.75%, 28.43%) and the other in the <25 age group (22.93%, 20.85%). Both total HPV and HR-HPV infection rates decreased to their lowest in the 25-34-year age groups. CONCLUSIONS: The prevalence of HPV infections showed a downward tendency with time. Single HPV genotype infections and HR-HPV infections were predominantly detected. The after prevalent characteristics of HPV can help to guide HPV vaccinations and cervical cancer screenings: 1) non-HPV16/HPV18 H R-HPV genotypes were prevalent; 2) non-vaccine-covered HPV53, HPV51 and HPV68 were also prevalent; 3) women above the age of 55 years had the highest HPV and HR-HPV infection rates.
