Objective:Precise prevention is more desired for cervical cancer due to the huge population,high prevalence of human papillomavirus (HPV) infection in China and the vision of screen-and-treat strategies in low-and middleincome countries (LMICs).Considerations of combining type-specific prevalence and attribution proportion to high-grade cervical intraepitheliai neoplasia are informative to more precise and effective region-specific cervical cancer prevention and control programs.The aim of the current study was to determine the genotype distribution of HPV and attribution to cervical precancerous lesions among women from rural areas in North China.Methods:A total of 9,526 women participated in the cervical cancer screening project in rural China.The samples of women who tested positive for HPV were retested with a polymerase chain reaction (PCR)-based HPV genotyping test.The attribution proportion of specific high-risk human papillomavirus (HR-HPV) types for different grades of cervical lesions was calculated by using the type contribution weighting method.Results:A total of 22.2% (2,112/9,526) of women were HR-HPV positive and HPV52 (21.7%) was the most common HR-HPV genotype,followed by HPV58 (18.2%),HPV53 (18.2%) and HPV16 (16.2%).The top three genotypes detected in HR-HPV-positive cervical intraepithelial neoplasia (CIN)1 were HPV16 (36.7%),HPV58 (20.4%),H-PV56 (15.3%).Among CIN2+,the most frequent genotypes were HPV16 (75.6%),HPV52 (17.8%),HPV58 (16.7%).HPV16,56,58,53,52,59,68,and 18 combined were attributed to 84.17% of all CIN1 lesions,and HPV16,58,and 52 combined were attributed to 86.98% of all CIN2+ lesions.Conclusions:The prevalence of HR-HPV infection among women from rural areas in North China was high and HPV16,HPV58,HPV52 had paramount attributable fraction in CIN2+.Type-specific HPV prevalence and attribution proportion to cervical precancerous lesions should be taken into consideration in the development of vaccines and strategy for screening in this population.
