Abstract
Objective
To assess whether ballet dancers have higher eating psychopathology mean scores than the general population.
Methods
Meta-analysis of cross-sectional observational studies comparing the scores of one or more of the validated eating psychopathological scales between ballet dancers and any control groups.
Results
Twelve studies were included in the metanalysis. Ballet dancers had a significantly higher EAT score (12 studies retrieved, SMD 0.82 [95% CI 0.44–1.19], p < 0.00001, I2 = 84)]; subgroup analysis suggested a possible role of control subjects’ choice in explaining heterogeneity. Scores on the EDI subscales of Drive for Thinness, Bulimia, and Body dissatisfaction were available from four studies; Drive for Thinness was higher in ballet dancers (SMD 0.62 [0.01, 1.22]), as well as the Bulimia scale (SMD 0.38 [0.02, 0.73], p = 0.04) and the Body Dissatisfaction scale (SMD 0.34 [0.15, 0.53]). Data on Perfectionism, Interpersonal problems, Ineffectiveness, and Maturity fears, were available from three studies. Higher scores in Perfectionism (SMD 0.68 [0.24, 1.12] p = 0.02), Interpersonal problems (SMD 0.24 [0.02, 0.47], in Inefficacy, (SMD 2.18 [1.31, 3.06]) were found for ballet dancers; on the other hand, Maturity fears scores were not significantly different between ballet dancers and controls (IV-MD = 0.15 [− 0.07, 0.36]). Seven studies reported tests not performed elsewhere.
Discussion
Ballet dancers show a higher level of restriction and drive for thinness than controls, and they may be, therefore, at higher risk for the development of eating disorders. Available studies do not allow the discrimination of dysfunctional eating attitudes and behaviors from adaptive responses.
Level of evidence
Level I (evidence obtained from systematic reviews and meta-analyses).
