Disordered Eating, Menstrual Irregularity, Bone Mineral Density in Female Runners. Med. Sci. Sports Exerc., Vol. 35, No. 5, pp. 711–719, 2003. Purpose: To examine the relationships between disordered eating, menstrual irregularity, low bone mineral density (BMD) young female runners. Methods: Subjects were 91 competitive distance runners aged 18 –26 yr. eating was measured by Eating Disorder Inventory (EDI). irregularity defined as oligo/amenorrhea (0 –9 menses per year). BMD dual x-ray absorptiometry. Results: An elevated score on EDI (highest quartile) associated with oligo/amenorrhea, after adjusting for percent body fat, age, miles run week, age at menarche, dietary (OR [95% CI]: 4.6 [1.1–18.6]). Oligo/amenorrheic had lower than eumenorrheic spine (5%), hip (6%), whole (3%), even accounting weight, score, menarche. Eumenorrheic scores normal (11%), trends differences weight fat. Runners both an no further reduction only one of these risk factors. Conclusion: In runners, (i) is strongly related to (ii) BMD, (iii) absence irregularity.
