Ballet dancers are at elevated risk for eating disorders, but the extent to which disordered eating attitudes and behaviors represent a relatively benign adaptation to an environment that values extreme thinness, or a functionally impairing form of psychopathology, has sparked considerable debate.
To determine whether disordered eating is associated with role impairment in dancers, we evaluated its association with musculoskeletal injuries among 239 adolescent female ballet students.
Dance students reported a variety of lifetime disordered eating behaviors to control weight including fasting (29.3%), vomiting (9.6%), and laxative use (4.2%). More than half (52.3%) reported a lifetime history of injury (stress fracture, broken bone, and/or medically treated tendonitis). A greater number of lifetime disordered eating behaviors was associated with a greater number of lifetime injuries (p=0.01). Moreover, vomiting history was associated with greater likelihood of injury (p=0.004) and increased time to recover from injury (median difference=22.8 days, p=0.006).
Although the direction of causality cannot be determined from this retrospective design, these results suggest that disordered eating is associated with role-relevant functional impairment, even among members of a subculture that values extreme thinness.
芭蕾舞演员面临着更高的饮食失调风险，但对于饮食失调的态度和行为是对极度消瘦环境的相对良性适应，还是代表一种功能失调的心理病理学形式，这引发了相当大的争议。
为了确定饮食失调是否与舞者的角色障碍有关，我们评估了它与 239 名青春期女性芭蕾舞学生的肌肉骨骼损伤之间的关系。
舞蹈学生报告了各种控制体重的终生饮食失调行为，包括禁食（29.3%）、呕吐（9.6%）和泻药使用（4.2%）。超过一半（52.3%）的学生报告有过终生受伤史（应力性骨折、骨折和/或经医学治疗的腱炎）。更多的终生饮食失调行为与更多的终生受伤有关（p=0.01）。此外，呕吐史与受伤的可能性更大（p=0.004）和受伤恢复时间的增加有关（中位数差异=22.8 天，p=0.006）。
尽管从回顾性设计中无法确定因果关系的方向，但这些结果表明，即使在一个重视极度消瘦的亚文化群体中，饮食失调也与角色相关的功能障碍有关。
