Bone Mineral Density in Active and Retired Ballet Dancers
We concluded that factors such as primary amenorrhea, low body weight, low energy intake, low calcium intake, and eating disorders can all lead to low BMD in dancers. However, in studies of retired dancers the effect of these risk factors on hip and lumbar spine BMD appears to be somewhat modulated, which may reflect that high impact activity during a key prepubertal age has a beneficial effect. The practical implication of these findings is that ballet, in moderation, and not associated with abnormal eating behavior or prolonged menstrual disturbance, can be seen as a positive lifestyle choice that may serve to decrease the risk of osteoporosis in later life.
