Injuries occur frequently among ballet and contemporary dancers. However, limited literature exists on injuries to pre-professional dancers in the USA. The goals of this study were to 1. provide a descriptive epidemiology of the incidence of musculoskeletal injuries in an adolescent and young adult dance population and 2. identify parsimonious regression models that could be potentially used to predict injury incidence. The study was based at the University of North Carolina School of the Arts (UNCSA) from Fall 2009 to Spring 2015. An injury was defined as any event that caused a dancer to be seen at the UNCSA Student Health Services and caused the dancer to modify or curtail dance activity for at least 1 day. Injury rate ratios (IRRs) were calculated using negative binomial generalized estimating equations. Models predicting injury rates were built using forward selection, stratified by sex. Among 480 dancers, 1,014 injuries were sustained. Most injuries were to the lower extremity and the result of overuse. There were differences in upper extremity, lower extremity, and traumatic injury rates by demographic subgroups. Among females, the most parsimonious predictive model for injury rates included a self-reported history of depression, age at time of injury, and number of injuries sustained at UNCSA prior to the semester of current injury. Among males, the most parsimonious model was a univariate model with family history of alcohol or drug problems. Strategies for traumatic injury prevention among dancers should be both sex- and style-specific. No differences were observed in overuse injury rates by sex or style, suggesting that generic overuse prevention strategies may not need to be guided by these factors. It is concluded that strategies can be implemented to reduce and mitigate the consequences of injuries if not the injuries themselves.
芭蕾舞演员和现代舞舞者经常受伤。然而，关于美国准职业舞者受伤情况的文献有限。本研究的目的是：1. 描述青少年和青年舞蹈人群肌肉骨骼损伤发生率的流行病学特征；2. 确定可用于预测损伤发生率的简约回归模型。该研究于2009年秋季至2015年春季在北卡罗来纳大学艺术学院（UNCSA）进行。损伤定义为任何导致舞者到UNCSA学生健康服务中心就诊，并使舞者至少1天改变或减少舞蹈活动的事件。损伤率比（IRR）使用负二项广义估计方程计算。预测损伤率的模型采用向前选择法构建，并按性别分层。在480名舞者中，共发生1014起损伤。大多数损伤发生在下肢，且是过度使用造成的。不同人口统计学亚组在上肢、下肢和创伤性损伤率方面存在差异。在女性中，最简约的损伤率预测模型包括自我报告的抑郁病史、受伤时的年龄以及当前损伤学期之前在UNCSA的受伤次数。在男性中，最简约的模型是一个单变量模型，涉及酒精或药物问题家族史。舞者创伤性损伤的预防策略应针对性别和舞蹈风格。未观察到按性别或风格划分的过度使用损伤率存在差异，这表明一般性的过度使用预防策略可能无需受这些因素的指导。研究得出结论，即使无法避免损伤本身，也可以实施相关策略来减少和减轻损伤的后果。
