OBJECTIVE: To assemble and synthesize the best evidence on the epidemiology,
diagnosis, prognosis, treatment, and prevention of disordered eating, menstrual
disturbances, and low bone mineral density in dancers.
DATA SOURCES: Medline,
CINAHL, PsycINFO, Embase, and other electronic databases were searched from 1966
to 2010 using key words such as "dance," "dancer," "dancing," "eating disorders,"
"menstruation disturbances," and "bone density." In addition, the reference lists
of relevant studies were examined, specialized journals were hand-searched, and
the websites of major dance associations were scanned for relevant information.
STUDY SELECTION: Citations were screened for relevance using a priori criteria,
and relevant studies were critically reviewed for scientific merit by the best
evidence synthesis method. After 2748 abstracts were screened, 124 articles were
reviewed, and 23 (18.5%) of these were accepted as scientifically admissible
(representing 19 unique studies). DATA EXTRACTION: Data from accepted studies
were abstracted into evidence tables relating to prevalence and associated
factors; incidence and risk factors; diagnosis; and prevention of disordered
eating, menstrual disturbances, and/or low bone mineral density in dancers. DATA
SYNTHESIS: The scientifically admissible studies consisted of 13 (68%)
cross-sectional studies and 6 (32%) cohort studies. Disordered eating and
menstrual disturbances are common in dancers. The lifetime prevalence of any
eating disorder was 50% in professional dancers, while the point prevalence
ranged between 13.6% and 26.5% in young student dancers. In their first year of
intensive dance training, 32% of university-level dancers developed a menstrual
disturbance. The incidence of disordered eating and low bone mineral density in
dancers is unknown. Several potential risk factors are suggested by the
literature, but there is little compelling evidence for any of these. There is
preliminary evidence that multifaceted sociocultural prevention strategies may
help decrease the incidence of disordered eating. CONCLUSIONS:
The dance medicine
literature is heterogeneous. The best available evidence suggests that disordered
eating, menstrual disturbances, and low bone mineral density are important health
issues for dancers at all skill levels. Future research would benefit from clear
and relevant research questions being addressed with appropriate study designs
and better reporting of studies in line with current scientific standards.
