Bone Loss in Patients With Anorexia Nervosa
Physiopathology of Bone Loss in Young Patient With Anorexia Nervosa
Nutritional deprivation of adolescent girls with anorexia nervosa (AN) reduces the bone mass acquisition. A better understanding of this process would improve the medical treatment of bone alteration and its long-term consequences.
160 patients (age < 38 yr) with AN and 160 age-matched controls (CON) will be enrolled in this study. The areal bone mineral density (aBMD) will be determined using dual-X-ray absorptiometry. Calciotropic hormones, bone turnover markers will be concomitantly evaluated.
