Human Papillomavirus Incidence and Risk Factors Among Mexican Female College Students
Bibliographic record
Abstract
OBJECTIVE: To determine the factors associated with high-risk human papillomavirus (HR-HPV) and its incidence in a cohort of female college students, with particular emphasis on the use of condoms. METHODS: A cohort was created during 2001 to 2005. The students signed informed consent, answered a questionnaire, and provided a vaginal scrape to detect HR-HPV. Incidences were estimated and risk factors were evaluated using Cox proportional risk model. The variable condom use was constructed based on the following 3 measurements: relative frequency throughout one's lifetime, use during the first sexual relationship, and use during the last sexual relationship. RESULTS: A total of 237 women participated, providing 395.6 person-years of follow-up. An incidence of 15.9 HR-HPV infection per 100 person-years was estimated and the factors associated with HR-HPV infection were found to be self-reported sexually transmitted infections (RR = 2.7), use of emergency contraception pill (ECP) (RR = 2.0), and having 2 or more sexual partners (RR = 1.9). University students using the ECP demonstrated more risky sexual behavior than nonusers. Women with 2 or more sexual partners who reported inconsistent condom use had 3.8 times the rate of HR-HPV infection. CONCLUSIONS: The incidence for HR-HPV in this cohort of Mexican female college students is comparable to that found in the United States and Canada. The results suggest that the consistent use of condoms is a protective factor against HR-HPV, especially for women with multiple sexual partners and/or those who use the ECP.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
