Dietary restraint and low bone mass in female adolescent endurance runners.

摘要

BACKGROUND: Because disordered eating (DE) has been related to menstrual irregularity (MI) and low bone mineral density (BMD) in some studies of female athletes but not in others, it seems beneficial to assess the DE attitudes and behaviors most associated with these conditions.

The EDE-Q, composed of subscales for weight concern, shape concern, eating concern, and dietary restraint, was used to assess DE.
