Objective To investigate human papillomavirus(HPV)infection in Jiading District of Shang-hai,and to explore the relationship between different HPV subtypes and cervical lesions.Methods A retro-spective analysis was conducted for HPV subtype results and pathological results during the same period of time from 19 030 patients who visited Maternity and Children Health Care Hospital of Jiading District from March 13th,2023 to March 31,2024,and underwent the HPV subtype detection.The relationship between HPV infection and age and cervical lesions were analyzed.Results Out of 19 030 samples,3 506 were HPV positive,and the infection rate was 18.42%.There were 2 185 cases of single infection and 1 321 cases of mul-tiple infection.The HPV infection rate in each age group were as below:the infection rates were 30.34%in≤20-year-old group,18.46%in 20-30 year-old group,16.46%in>30-40 year-old group,14.83%in>40-50 year-old group,21.29%in>50-60 year-old group and 32.74%in>60 year-old group,and there was a statistically significant difference in HPV infection rates among different age groups(P<0.001).The top 5 subtypes were type 52(21.50%),53(10.84%),58(10.02%),33(8.33%)and 59(6.85%).The proportions of the who progressed to higher-level cervical lesions in individuals with HPV subtypes of the top 5 infection rates,as well as those with HPV16 and 18 positive,were significantly higher than that in HPV negative indi-viduals,among which the individuals with HPV16,18,58,and 33 were more likely to progress to severe cervi-cal lesions[atypical squamous cells:cannot exclude high-grade squamous intraepithelial lesion(ASC-H)+low-grade squamous intraepithelial lesion(LSIL)+high-grade squamous intraepithelial lesion(HSIL)+squamous cell carcinoma(SCC)](P<0.05).Compared to HPV 52 positive individuals with the highest infection rate,HPV 16,18,58,and 33 positive individuals were more likely to progress to higher-level cervical lesions(P<0.05).Conclusion HPV infection rates in≤20 year-old group and>60 year-old group are relatively high in Jiading District of Shanghai.The risk of progression to cervical lesions varies among different HPV subtypes.In addition to HPV 16 and 18,HPV 58 and HPV 33 are also closely related to higher levels of cervical lesions and should be given sufficient attention.
