The epidemiologic characteristics of human papillomavirus (HPV) genotypes vary by age, ethnicity, and geographic location, and the available data on HPV epidemiological characteristics with cytology results in Sichuan province are limited. Our research was conducted from June 2016 to July 2017. A total of 10 953 women getting HPV testing were enrolled. Liquid‐based cytological and histological results were collected. The overall HPV infection rate was 24.1% in Sichuan province. The prevalence of high‐risk HPV (hrHPV) was 19.9%. For hrHPV genotypes, HPV52 (15.5%) was the most prevalent genotype, followed by HPV16 (13.8%), HPV58 (13.3%), HPV51 (8.6%), HPV39 (8.1%), and HPV68 (7.8%). Among all HPV‐positive women with a cytology or histology result, HPV16‐positive women have the highest cervical intraepithelial neoplasia 1 (CIN1)+ prevalence (11.1%), followed by HPV18 and HPV33; HPV16‐positive women also have the highest CIN2+ prevalence (9.3%), followed by HPV58 and HPV18. To date, this is the largest study done in the Sichuan province for HPV prevalence and subtype distribution with normal and abnormal cytological results. The age‐specific prevalence in patients at gynecology clinics and other clinics is different. Besides, patients at the same age also have a different hrHPV prevalence and lrHPV prevalence. Our result revealed that in every 10 HPV16‐positive women, there is approximately one women with CIN2, CIN3, or cervical cancer. A higher oncogenic potential of HPV58 than that of HPV52 was observed.
