title: Viewership of pro-anorexia websites in seventh, ninth and eleventh graders.
abstract: OBJECTIVE
  To examine the prevalence of visiting pro-anorexia websites by 13-, 15- and 17-year old adolescents and to explore correlates of visiting such websites and predictors of anorexia nervosa (AN).
  
  
  METHODS
  Questionnaire in a sample of 711 secondary school children from the 7th, 9th and 11th grade in Flanders, Belgium.
  
  
  RESULTS
  12.6% of the girls and 5.9% of the boys had visited such websites. In girls, visiting pro-anorexia websites was associated with a higher drive for thinness, worse perception of appearance and more perfectionism.
  
  
  CONCLUSIONS
  The prevalence of visiting pro-anorexia sites is non-trivial and the significant correlations between viewership of pro-ana sites and predictors of AN suggest a potential for negative impact of exposure to pro-ana sites. We conclude with some speculative remarks on the potential threat of the existence of pro-ana sites to organized health care.
