The tendency of eating disorder observed by Anorexia Bulimia Inventory questionnaire(Stein & Jensen, 1995). Bone mineral density was measured by Quantitative Ultrasonography(QUS), and participants were classified as normal(T-score > -0.99: n=61) and osteopenia(T-score between -1.0 and -2.5: n=97) following WHO guidelines. Statistical analysis in Frequency analysis, Reliability analysis, Factor analysis(varimax), Analysis of Covariance(ANCOVA), were performed with adjustment of age, weight, career, regular or irregular of menstrual period, and age at menarche. All statistical procedures were performed by SPSS(Ver 18.0) windows. There was a significant differences on psychological anxiety between normal and osteopenia(p<.05), but there were no significant differences on depression, binge eating, weight loss, body satisfaction between two groups.
