To investigate the role of human papillomavirus (HPV) infection and associated co-factors in the development of high-grade cervical neoplasia while evaluating new screening technologies.
Enumerated adult women aged 18 and older via census sampling in Guanacaste, Costa Rica, enrolling and interviewing 10,049 of 10,738 eligible women (93.6% participation rate).
Conducted pelvic examinations on sexually active participants to collect samples for three cervical cytology methods, 16-type HPV DNA testing, vaginal pH assessment, cervicography, and blood biomarkers.
Referred participants with abnormal cytology or positive cervicography for colposcopy and biopsy, establishing a cohort followed annually to evaluate incident high-grade squamous intraepithelial lesions.
Enrolled 10,049 women (93.6% response rate) into the baseline screening cohort to establish a population-based case-control and prospective natural history study.
Implemented a multimodal screening protocol integrating conventional cytology, cervicography imaging, and multi-type HPV DNA detection to characterize baseline lesion prevalence and risk-factor exposures.
