title: Sexual experiences in relation to HPV vaccination status in female high school students in Sweden.
abstract: OBJECTIVE
  To investigate sexual experiences, sexually transmitted infections (STIs) and use of condoms in relation to human papillomavirus (HPV)-vaccination status in female high school students.
  
  
  METHODS
  In 2013, 355 female students with a median age of 18 years from randomly selected high schools in Sweden answered a classroom questionnaire on sexual experiences and HPV-vaccination status.
  
  
  RESULTS
  In total 227/348 (65%) of the women reported having received at least one HPV vaccine dose. Median age at first intercourse was 15 and 16 years respectively, in the 141/227 (62%) vaccinated after, and the 86/227 (38%) vaccinated before their sexual debut. There were no differences between the HPV-vaccinated and non-vaccinated groups regarding condom use, STIs, and experiences of oral and anal sex, or friends- with-benefit relationships. However, having had sexual intercourse and 'one-night stands' were more common in the vaccinated group (both p < 0.05).
  
  
  CONCLUSIONS
  Many students (62%) were vaccinated against HPV, with two-thirds after their sexual debut. There were no differences in condom use and STIs, and only a few differences in sexual experiences between the HPV-vaccinated and non-vaccinated groups. Initiating HPV vaccination before sexual debut is important, as is information about the link between HPV, sexual behaviour and cancer.
