title: Prevalence of eating disorders symptoms in nonelite ballet dancers and basketball players: An exploratory and controlled study among French adolescent girls.
abstract: BACKGROUND
  Until recently, very few controlled studies have examined the prevalence of eating disorders (ED) symptoms among nonelite adolescent female athletes. Moreover, results are mixed and inconclusive. Therefore, the aim of this exploratory study was to examine the prevalence of ED symptoms (underweight, bulimia, drive for thinness, body dissatisfaction) among French nonelite adolescent female athletes (ballet dancers and basketball players) and nonathletes.
  
  
  METHODS
  The sample of adolescent girls (aged between 12 and 16 years), consisted of 43 basketball players, 52 ballet dancers and 49 nonathlete controls. The eating disorder inventory and a demographic-personal information questionnaire (date of birth, experience of ED, week training time, etc.) were filled out by the participants. Additionally, all participants were measured and weighed. The frequencies of ED symptoms were compared between the groups (athletes versus nonathletes, ballet dancers versus basketball players) using a series of χ² tests.
  
  
  RESULTS
  The χ² tests did not show significant differences in frequencies of underweight and body dissatisfaction symptoms between nonelite athletes and nonathletes. However, results highlighted a nonsignificant trend toward higher frequency of: (i) drive for thinness (P=0.05) symptoms in nonelite athletes compared with nonathletes, and (ii) bulimia (P=0.06) symptoms in nonathletes compared with nonelite athletes. Additional analyses performed among the sport groups revealed that the prevalence of drive for thinness symptoms was significantly two-fold higher in ballet dancers than basketball players (34.6% versus 16.3%). Nevertheless, no significant differences were found in the frequencies of underweight, bulimia and body dissatisfaction symptoms among the sport groups.
  
  
  CONCLUSIONS
  This study showed that the frequency of ED symptoms is equivalent in nonelite athletes and nonathletes. However, these nonsignificant results should be interpreted with caution regarding the weak statistical power of the analyses and the small sample size. Detailed analysis revealed a significantly higher prevalence of drive for thinness symptoms in ballet dancers in comparison with basketball players. Consequently, these results should be viewed as preliminary and further studies are needed before they can be generalized to French adolescent female athletes.
