To compare and research human papillomavirus(HPV)infection status and distribution of HPV genotypes among the women in Shangluo,Ankang,and Hanzhong,provide a reference for cervical cancer screening.Methods HPV genotyping was performed in cervical exfoliative cell specimens of 1 901 women from Shangluo,2 703 women from Ankang,and 3 058 women from Hanzhong by PCR reverse spot hybridization technology.Results In Shangluo,the total HPV infection rate was 60.07%,high-risk HPV infection rate and low-risk HPV infection rate were 51.18%and 26.14%,respectively.In Ankang,the total HPV infection rate was 21.94%,high-risk HPV infection rate and low-risk HPV infection rate were 19.09%and 4.48%,respectively.In Hanzhong,the total HPV infection rate was 42.67%,high-risk HPV infection rate and low-risk HPV infection rate were 40.88%and 4.35%,respectively.The total HPV infection rate and high-risk HPV infection rate in Shangluo were the highest,followed by Hanzhong,which were the lowest in Ankang,there was statistically significant difference(P<0.05).The low-risk HPV infection rate in Shangluo was statistically significantly lower than those in Ankang and Hanzhong(P<0.05).There was no statistically significant difference in the low-risk HPV infection rate between Ankang and Hanzhong(P>0.05).The total HPV infection rate and high-risk HPV infection rate in Shangluo were the highest in each age group,followed by Hanzhong and Ankang.There was no statistically significant difference in high-risk HPV infection rates of women in 51-60-year-old group and≥61-year-old group between Shangluo and Hanzhong,while there were statistically significant differences in high-risk HPV infection rates of women in other age groups(P<0.05).The low-risk HPV infection rate in each age group in Shangluo was statistically significantly higher than those in Hanzhong and Ankang(P<0.05).The low-risk HPV infection rate of women in≥61-yearold group in Ankang was statistically significantly higher than that in Hanzhong,there was no statistically significant difference in low-risk HPV infection rate of women in other age groups between Ankang and Hanzhong(P>0.05).HPV 16 was the most common HPV genotype in the three cities,followed by HPV 58,HPV 66,HPV 33,HPV 18,HPV 52 in Shangluo,HPV 52,HPV 58,HPV 53,HPV 39,HPV 33 in Ankang,HPV 58,HPV 52,HPV 53,HPV 39,HPV 33 in Hanzhong.The common low-risk HPV genotypes in Shangluo were HPV 6,HPV 43,HPV 42,HPV 11,HPV 81.The common low-risk HPV genotypes in Ankang were HPV 81,HPV 11,HPV 6,HPV 42,HPV 43.The common low-risk HPV genotypes in Hanzhong were HPV 6,HPV 43,HPV 11,HPV 81,HPV 42.Single HPV infection was the most common type in the three cities,followed by double HPV infection,triple HPV infection or above were not common.The single HPV infection rate in Ankang was statistically significantly lower than those in Shangluo and Hanzhong(P<0.05).The double HPV infection rate,triple HPV infection rate or above in Shangluo were the highest,followed by Hanzhong and Ankang(P<0.05).The single lowrisk HPV infection rate and double low-risk HPV infection rate in Hanzhong were statistically significantly lower than those in Shangluo and Ankang(P<0.05).The single high-risk HPV infection rate in Hanzhong was the highest,followed by Shangluo and Ankang(P<0.05).There was no statistically significant difference in double high-risk HPV infection rate among the three cities(P>0.05).The triple highrisk HPV infection or above in Shangluo were the highest,followed by Hanzhong and Ankang(P<0.05).The double mixed HPV infection rate,triple mixed HPV infection or above in Shangluo were statistically significantly higher than those in Ankang and Hanzhong(P<0.05).Conclusion HPV infection in Shangluo,Ankang,and Hanzhong has different characteristics.Researching HPV infection statuses in different regions has improtant significance in prevention and treatment of cervical cancer.
