Cervical cancer is the commonest cancer affecting women worldwide. During the last decades, the incidence and mortality rates of cervical cancer have increased in China. This research aims to assess the overall and genotype-specific prevalence of the human papillomavirus (HPV) infection among Chinese women with normal cervix, considering age, and geographic location. We selected studies about HPV prevalence in women from Chinese in Mainland China with normal cervix and abnormal cervical lesions, published between January 1995 and December 2020. The HPV prevalence was analyzed using meta-analysis based on the following: cytological and histological diagnoses, regions, and ages. The overall HPV prevalence in 856,535 women was 14.3%, 95% confidence interval (CI) and it increased from 8.2% to 16.5% in studies published from 2006 to 2020. The prevalence of high-risk (HR) and low-risk (LR) HPV types was 11.3% and 2.7%, respectively. The commonest types of HPV in women from Mainland China were HPV 16 (2.6%), 52 (2.4%), 58 (1.7%), 18 (0.9%), and 33 (0.8%). According to the geographical analysis, the prevalence of different HPV genotypes varied by region, Central China had the highest overall HPV prevalence. HPV16 was the commonest type in all the regions except in South China and East China, where HPV52 was found to be common. Regarding diagnosis, the HPV infection led to cervical cancer diagnosis by cytology and histology with 90.1% and 91.5% rates, respectively. HPV16 and HPV18 were common types associated with cervical cancer diagnosed by cytology and histology. HPV 16, 58, 52, 18, and 33 were the commonest types found in women with normal cervixes from Mainland China. The prevalence of different HPV genotypes varied by age group and region.
