SUMMARY:

Ballet dancers constitute a risk group for the development of eating disorders (ED) due to the strict demands on physical performance, contributing to body image dissatisfaction (BI). This study aimed to compare the presence of ED risk behaviors, the perception of BI and the associations with anthropometric nutritional status and body composition in groups of female dancers, gymgoers and sedentary women. This is a comparative study involving 19 participants in each group, conducted from August 2016 to June 2018. Body Mass Index (BMI) was  alculated and body fat percentage (% BF) was analyzed and bone mineral density (BMD) by dual X-ray absorptiometry (DXA). To assess the risk behaviors for ED, the Eating Attitudes Test (EAT-26), directed to Anorexia Nervosa (AN) and Bulimic Investigatory Test Edinburgh (BITE), focused on Bulimia Nervosa (BN) behaviors were used. For the perception of BI, the Body Shape Questionnaire (BSQ) and Silhouette Figure Scale (EFS) were applied. In ballet dancers, BMI and % BF were significantly lower when compared to the other groups (one-way ANOVA, p <0.05). Total body bone mineral density (BMD) by DXA was within the expected limits for age, not differing between groups, averaging 0.4 (0.8) Z-scores. EAT-26, BITE and BSQ scores did not differ between the groups studied. The presence of BI distortion assessed by the EFS was higher among sedentary and gym-goers (68.8% in ballet dancers, 70.6% in gym-goers and 100.0% in sedentary women, p = 0.028), but dissatisfaction with BI was not differed between groups (68.8% in ballet dancers, 75.0% in gym-goers, 89.5% in sedentary women, p = 0.306). BMI and % BF showed a positive correlation with the BSQ score in the dancers (BMI: r2 = 0.657, p = 0.002; % BF: r2 = 0.574, p = 0.010). In gym-goers, % BF showed a negative correlation with the EAT-26 score (r2 = - 0.571, p = 0.013). In sedentary women, BMI positively correlated with EAT-26 score (r2 = 0.462, p = 0.047) and BSQ score (r2 = 0.653, p = 0.002), % BF positively correlated with BSQ score (r2 = 0.524, p= 0.026) and BMD negatively correlated with BITE score (r2 = - 0.537, p = 0.039). It was concluded that the presence of ED risk behaviors and BI dissatisfaction in the dancers was not different when compared to the gym-goers and sedentary women. BI distortion was less present in the ballet dancers when compared to the other groups studied. BMI and % BF correlated differently in the studied groups with behaviors suggestive of ED and BI perception, and BMD was important only in the sedentary group.
