BACKGROUND: High risk human papillomavirus (hrHPV) infection is associated with the development of cervical cancer (CC) in 99.7%. The prevalence of HPV varies according to the geographic region, lesion degree, method of detection, among other variables.
OBJECTIVE: To determine the prevalence of hrHPV and identify some risk factors in a group of women with cervical lesions from Mexico City.
MATERIAL AND METHODS: Of 421 women, 310 were included. Questionnaires of risk factors were administered, and cervical samples which included the entire spectrum of cervical lesions according to the Bethesda system were obtained. HPV genotyping was made with INNO-LiPA system. Population characteristics were analyzed with descriptive statistics. Risk factors’ odds ratio (OR) was calculated with chi squared using SPSS software, version 24.0.
RESULTS: 91.6% of the samples were positive for hrHPV. The prevalent types were 16, 66, 52 and 51. By age group there were not statistically significant differences in the risk of HPV infection. Having had three or more sexual partners increased the risk of infection by hrHPV (OR: 2.99; 95% confidence interval [95% CI]: 1.247.24). Sexually transmitted diseases increased the probability of infection by hrHPV different to types 16, and 18 (OR: 2.47; 95% CI, 1.24-7.24 and 1.50-4.06).
CONCLUSIONS: The high prevalence of types 66, 52 and 51 is a finding that has not been described previously in our population. We hope that this study will help to improve health services in order to decrease the incidence of cervical cancer.
