Formatted abstract
Abstract Anorexia nervosa (AN) can lead to osteoporosis and fractures.

Objective This study evaluated adolescent females with AN diagnosed within the previous 12 months to determine whether there is bone mass reduction and to investigate relationships between nutritional indices (weight, body mass index [BMI], lean mass, fat mass, and percentage fat) and total body (TB) and lumbar spine (LS) bone mineral densities (BMD) and content (BMC).

Method
TB and LS BMD and BMC and body composition were measured in 24 adolescent females with AN.

Results
There was no significant reduction in TB or LS BMD. Regression analysis shows significant correlation (p < .001) between lean mass and TB BMD (r = +.83), TB BMC (r = +.92), LS BMD (r = +.81), andLS BMC (r = +.92). There was also a significant relationship between weight percentile and LS BMD z score (p < .005; r = +.60).

Discussion Adolescent females with early AN do not appear to have reduced bone mass. Lean mass is correlated to BMD and BMC.
