A population-based five-year follow-up study of cervical human papillomavirus infection

Objective: The purpose of this study was to determine the long-term tendency for cervical human papillomavirus infections to persist in the general population. Study Design: From 500 women who participated in a 1991 population-based survey, 90 healthy women with normal results of cytologic examination (women with human papillomavirus deoxyribonucleic acid detected and age-matched control women without human papillomavirus deoxyribonucleic acid detected) were interviewed and examined 5 years later colposcopically, cytologically, and with human papillomavirus serologic testing and human papillomavirus deoxyribonucleic acid testing by polymerase chain reaction with 2 different consensus primer pairs (MY09 and MY11 and GP5+ and GP6+), type-specific polymerase chain reaction, and deoxyribonucleic acid sequencing. Results: The 5-year human papillomavirus clearance rate was 92%. Only human papillomavirus type 16 infections persisted. Colposcopic impression of grade 2 cervical intraepithelial neoplasia was associated with persistent human papillomavirus 16 infection (P< .03). Human papillomavirus detection was associated with sexual history. Human papillomavirus type was the only determinant of human papillomavirus persistence. Conclusion: The high clearance rates in a population-based setting with a 5-year follow-up period imply that inclusion of human papillomavirus deoxyribonucleic acid testing in population-based cervical screening programs should target persistent infection.
