Abstract
Abstract. There is little known on the impact of eating disorders on bone density in college-aged physically active males. This analysis included 70 Caucasian/Asian males that had 4 years of bone mineral density (BMD) measurements of the spine and hip and completed the Eating Disorder Inventory (EDI-2). Slopes of change in spine and hip BMD were determined over 4 years. The only baseline differences were that males in the highest EDI quartile were heavier (173 vs. 158 lb, respectively, p = 0.06) and daily calcium intake was significantly lower (1620 mg vs. 1743 mg, respectively, p = 0.03). Calcium intake was not related to 4-year change in spine or hip BMD. EDI score was inversely related to 4-year change in both spine BMD ( r = − 0.165, p = 0.17) and hip BMD ( r = − 0.288, p p = 0.04). These differences persisted when controlling for weight and calcium intake. There is a possibility that subclinical eating disorders exist in a college age physically active population of males and could have significant detrimental effects on bone gain.
