The relationship between contraceptives, sexual practices, and cervical human papillomavirus infection among a college population

Abstract

Four hundred and sixty-five college women were evaluated to determine if specific variables of social and sexual behavior correlated with the presence of human papillomavirus (HPV) DNA in the genital tract, and if these associations differed between women who were HPV DNA positive, HPV DNA positive/clinically (cytologically) negative, or who reported previous HPV-related disease by a history of an abnormal Papanicolaou (Pap) smear or genital warts. HPV positive women had more sexual partners in the recent past, more sexual episodes per month, and used spermacides less commonly than controls. Similarly, self-reporters were more likely to have more lifetime sexual partners and earlier age of onset for sexual activity. Cytologically negative HPV positive women were distinguished only by more sexual episodes per month and sexual partners in the past year (borderline significance). Alcohol use was significantly more frequent in all groups, underscoring this variable as a risk factor for both HPV DNA positivity and related disease in young women. Potential explanations for differences between women with clinically and non-clinically related HPV positivity are discussed, with emphasis on the need for followup studies to determine if an epidemiologically distinct subset of HPV DNA positive but clinically negative women are at risk for subsequent cervical disease.
