Abstract

To explore factors affecting human papillomavirus (HPV) prevalence in all grades of cervical neoplasia among Chinese women, 1,264 women with abnormal cervical cytology attending the gynaecologic clinics of 11 major medical centres in Taiwan. Patients were interviewed and underwent complete gynaecologic examination including colposcopy. Cervical scrapings were collected for HPV DNA detection by both Hybrid Capture-2 (high-risk probe) and L1 consensus PCR-reverse line blot. The prevalences of HPV in the four different diagnosis groups: (i) suspicious (n = 316), (ii) low-grade intraepithelial lesion (n = 474), (iii) high-grade intraepithelial lesion (n = 450), and (iv) cancer (n = 16), were 36.1%, 74.7%, 83.6%, and 100%, respectively. In the latter two groups, Patients less than 30 or 40 years old, respectively, tended to be infected more frequently with HPV than the older patients were. The main correlates of HPV prevalence were lifetime number of sex partners (odds ratio (OR) for two or more partners: 2.44; 95% CI, 1.44-4.15), vaginal douching after intercourse (OR for douching frequently: 1.44; 95% CI, 1.01-2.04), vitamin supplementation (OR for regular vitamin supplement: 0.71, 95% CI, 0.55-0.92), and performance of Pap smear tests (OR for never having a Pap smear performed: 2.22; 95% CI, 1.19-4.17). The risk for vaginal douching was augmented by the promiscuity of sex partners (OR of 3.19 (1.91-5.34)) and smoking (OR of 1.90 (1.15-3.13)), whereas vitamin supplementation reduced the odds ratio to 1.35 (0.85-2.15). The results of this study provide further evidence of the role of HPV in cervical carcinogenesis. The data also indicate the main areas of risk for the prevalence of HPV in cervical neoplasia in Chinese women living in Taiwan.
