The objective of this study was to determine human papillomavirus (HPV) prevalence and identify factors associated with infection in sexually experienced and inexperienced females initiating HPV vaccination.

Methods

Participants were 13- to 21-year-old females receiving their first HPV vaccine dose, recruited from an adolescent primary care clinic between June 2008 and June 2010. These data are from the baseline visit of a longitudinal study that was approved by the hospital's institutional review board. Each participant completed a questionnaire assessing sociodemographic factors and behaviors. History of sexual contact was assessed using the following item: “Have you ever had sexual contact with a male or female (by sexual contact we mean genital, skin-to-skin contact only)?” Sexual experience was defined as a response of yes to the following item: “Have you ever had sex with a male or female (by sex we mean vaginal or anal sex)?” Cervicovaginal swabs were self- or clinician-collected and tested for HPV DNA.1,2 Logistic regression models were estimated to determine variables associated with HPV infection in sexually experienced and inexperienced females. The outcome measure was infection with 1 or more HPV types.
