Objective: The present study aimed to analyze the human papillomavirus (HPV) infection rate and subtype infection among 14 794 samples in Guangzhou, and to explore the association between HPV infection and ThinPrep Cytology Test (TCT). Furthermore, it evaluated the epidemiological features of HPV infection in Guangzhou, Guangdong Province, provided epidemiological insights into HPV infection among men, and assessed the significance of combined HPV and TCT testing in cervical cancer screening for women and in devising vaccination strategies against HPV. Methods: Sample data from 14,794 individuals who underwent genotyping for 37 HPV subtypes at the Second Affiliated Hospital of Guangzhou University of Chinese Medicine between January 2023 and December 2023 were collected. Concurrent analysis of TCT screening results was conducted to statistically examine the HPV infection characteristics across different ages, genders and seasons, as well as the relationship between single HPV infection, multiple HPV infection and TCT results. Results: The overall HPV infection rate stood at 29.42%. The most prevalent HPV subtype infections were HPV52 (21.55%), HPV58 (10.00%), HPV16 (9.17%), HPV51 (8.37%), HPV39 (7.56%), HPV61 (7.34%), and HPV53 (7.01%). The infection rate was 29.03% among women and 43.25% among men. The HPV infection rate exhibited a close correlation with age distribution, with statistically significant variations noted in the overall infection rate, single infection rate, and multiple mixed infection rate across different age groups ( X2=144.641, 30.797; P<0.001). Seasonal variations in infection rates were also observed, with rates of 28.03% in spring, 28.58% in summer, 29.56% in autumn, and 32.26% in winter. Among single infections, the highest infection rate of high-risk subtypes occurred in summer (43.53%), while among multiple infections, the higher infection rate was noted in autumn (35.02%). The TCT groups were predominantly characterized by single infections. Significant differences were discernible between single infections and multiple infections within each TCT group ( X2=90.497, P<0.001). Notably, TCT results also varied significantly among different age groups ( X2=32.871, P<0.001). Conclusion: The present study illuminated the epidemiological profile of HPV infection in the Guangzhou area, with an overall infection rate of 29.42%. HPV52, HPV58, and HPV16 emerged as the most frequent types. The overall HPV infection rate among men (43.25%) surpassed that among women (29.03%). The HPV infection rate showed a strong correlation with age distribution and was higher in summer and autumn compared to spring and winter. Additionally, this study identified significant differences in HPV infection rates among TCT groups and TCT results across different age groups, furnishing a scientific rationale for early HPV screening and presenting novel perspectives on cervical cancer prevention and treatment. In summary, this study contributes vital epidemiology data on HPV infection in Guangzhou, providing a scientific foundation for the formulation of targeted HPV prevention and control strategies and enhancement of cervical cancer diagnosis and treatment. It underscores the crucial role of male HPV infection in HPV prevention and control efforts.
