Intraepithelial Lesions

Objective: To establish associations between risk factors and the presence of intraepithelial lesions and human papillomavirus infection. Methods: Cross-sectional study with 1639 from the Santos Marquina municipality, Mérida, Venezuela. Cervical cytology and colposcopy, human papillomavirus detection and genotyping were analyzed using PCR and surveys to measure risk factors. Results: 477 women (31.8%) had human papillomavirus infection and 82 women (5.6%) had abnormalities in cervical cytology. Among the cases where human papillomavirus genotyping was performed, 135 (42%) correspond to low-risk types, while 177 (55%) correspond to high-risk types. A higher proportion of abnormal cytologies was found in cases with high-risk human papillomavirus with 21 cases (13.4%) compared to low-risk human papillomavirus with 9 cases (6.4%). The number of lifetime sexual partners greater than 1 (OR=2,303; p=0.001) and the history of pregnancy (OR=3,283; p=0.036) were significant independently associated with the presence of abnormal cytology. While the number of lifetime sexual partners greater than 1 (OR=1.304; p=0.026), the residence in rural area (OR=1.957; p <0.001) and the age under 35 years (OR=1,397; p=0.003) were significant independently associated with the presence of human papillomavirus infection. Conclusion: The type of human papillomavirus and other risk factors play an important role in the appearance of cervical intraepithelial lesions.

Potential Risk Factors

ObjectiveTo evaluate the association between potential risk factors for high-risk human papillomavirus (HR-HPV) infection and cofactors for cervical intraepithelial lesions grade 2 or worse (CIN2+) in women attending cervical screening in Amazonian Peru.Materials and MethodsParticipants completed a risk factor questionnaire before screening. High-risk human papillomavirus infection was determined by Hybrid Capture II. Logistic regression was used to evaluate associations between potential risk factors for HR-HPV infection and between cofactors and risk of CIN2+ among women with HR-HPV infection.ResultsScreening and questionnaires were completed by 5435 women aged 25 to 49 years. The prevalence of HR-HPV was 12.6% (95% confidence interval [CI], 11.8%–13.6%) and decreased by age. Early age at first sexual intercourse and several lifetime sexual partners increased the risk of having HR-HPV (age-adjusted odds ratio [AOR] of age at first sexual intercourse <18 vs ≥20, 1.5; 95% CI, 1.2–2.0; AOR of ≥5 lifetime sexual partners vs 1, 2.1; 95% CI, 1.4–3.2). Among women with HR-HPV infection, those with no schooling (AOR relative to 1–5 years of schooling, 3.2; 95% CI, 1.3–8.3) and those with parity ≥3 (AOR relative to parity <3, 2.6; 95% CI, 1.4–4.9) were at increased risk of CIN2+. The effect of parity was stronger for cancer (AOR of parity ≥3 vs <3, 8.3; 95% CI, 1.0–65.6). Further analysis showed that the association between parity and CIN2+ was restricted to women younger than 40. Most women (83%) had previously been screened. Sixty-four percent of CIN2+ cases detected in this study occurred in women who reported having had a Papanicolaou test in the previous 3 years. Only 4 of 20 cancers were detected in women never screened before. Having had a previous abnormal Papanicolaou test increased the risk of CIN2+ (OR, 16.1; 95% CI, 6.2–41.9).ConclusionAmong women with HR-HPV, high parity (in young women), no schooling, lack of good-quality screening and of adequate follow-up care are the main risk factors for high-grade cervical disease in Peru.
