ABSTRACT
BACKGROUND: Several studies have investigated injuries of (pre-)professional ballet dancers, however most used a medical-attention and/or time-loss definition and did not analyse the prevalence of all health problems. The aim was to analyse the frequency and characteristics of all self-reported physical and mental health complaints (i.e. injuries, illnesses and mental health problems) of professional ballet dancers during one season. METHODS: Three professional ballet companies were prospectively monitored weekly during one season with the Performing artist and Athlete Health Monitor (PAHM). Numerical rating scales (ranging 0-10) were used for severity of musculoskeletal pain, all health problems and impairment of the ability to dance at full potential in the previous seven days. If dancers rated the severity of their health problems or their impairment greater than 0, they were asked to answer specific questions on the characteristics of each health problem. RESULTS: Over a period of 44 weeks, 57 dancers (57.9% female) filled in 1627 weekly reports (response rate of 64.9%), in which 1020 (62.7%) health problem were registered. The dancers reported musculoskeletal pain in 82.2% of the weeks. They felt that their ability to dance at their full potential was affected due to a health problem in about every second week (52.6%) or on at least 29.1% of the days documented in the weekly reports. Almost all dancers (96.5%) reported at least one injury, almost two thirds (64.9%) an illness and more than a quarter (28.1%) a mental health problem. On average, every dancer reported 5.6 health problems during the season. Most of the 320 health problems were injuries (73.1%), 16.9% illnesses and 10.0% mental health problems. Injuries affected mainly ankle, thigh, foot, and lower back and were mostly incurred during rehearsal (41.6%) or training (26.1%). The most frequent subjective reasons of injury were "too much workload" (35.3%), "tiredness/exhaustion" (n = 22.4%) and "stress/overload/insufficient regeneration" (n = 21.6%). CONCLUSION: Preventive interventions are urgently required to reduce the prevalence of health problems and especially injuries of professional dancers. Injury prevention measures should regard the balance of the load capacity of professional dancers and the workload in training, rehearsals and performances.
ABSTRACT
BACKGROUND: Mental health problems cover a wide spectrum. Depression and anxiety disorders are the most frequent mental health problem in the general population and in elite athletes. The aim of the present study was to assess the prevalence of symptoms of depression, generalised anxiety disorder and eating disorders in professional dancers, to compare the results between genders and to the general population and to analyse potential determinants. METHODS: During a pre-season health screening, professional dancers of six German companies answered a comprehensive questionnaire on personal and dancer-specific characteristics, medical history and the Patient Health Questionnaire (PHQ-9), Generalised Anxiety Disorder Questionnaire (GAD-7) and Eating-Disorder-Examination-Questionnaire (EDE-QS). RESULTS: A total of 82 (55.8%) female and 65 (44.2%) male dancers answered the questionnaire. One in five (20.8%) dancers had at least moderate symptoms of either depression, generalised anxiety disorder or eating disorders. The prevalence of at least moderate symptoms of depression was 11.1% in female and 6.4% in male dancers, of generalised anxiety disorder 16.0% in female and 6.4% in male dancers and of eating disorders 14.8% in female and 6.1% in male dancers. Compared to the general population of the same gender and similar age, the prevalence of at least moderate symptoms of generalised anxiety disorder was significantly higher in both genders. About one in four dancers (26.9%) reported a subjective need for support from a psychotherapist at the time of the screening. The PHQ-9, GAD-7 and EDE-QS sum scores were not related to the size or type of the companies, the age or rank of the dancers, but the PHQ-9 and GAD-7 sum score were significantly related to severity of musculoskeletal pain in the past seven days and to chronic or recurrent symptoms of low mood and generalised anxiety. CONCLUSION: The prevalence of symptoms of depression, generalised anxiety and eating disorders was high in professional dancers. Routine screening and low-threshold interventions to improve mental health of professional dancers are recommended.
