ABSTRACT
OBJECTIVE:
Eating disorders (EDs) are associated with decreased bone mineral density (BMD) and increased fracture risk. The association between BMD and fracture risk in EDs is not well elucidated. We aimed to assess BMD in an ED cohort of patients with active disease and patients in remission, and to assess the predictive value of BMD on incidence of fractures.METHOD:
We included 344 female patients (median age 19, IQR 16; 24) referred to ED treatment. Later, patients were invited to follow-up including assessment of remission status and a dual-energy x-ray absorptiometry (DXA)-scan. Information on fractures was obtained through the Danish National Registry of Patients.RESULTS:
Patients with current anorexia nervosa (AN) had significantly lower BMD compared to controls at lumbar spine (16% lower, p < .0001), femoral neck (18% lower, p < .0001), and total hip (23% lower, p < .0001). Recovered AN patients had higher BMD compared to those with current disease (p < .0001 for all measures), but lower BMD compared to controls at lumbar spine (p < .01) and hip (p < .001). BMD did not differ between BN patients and controls. In patients with active eating disorders not otherwise specified, BMD was lower only at the total hip (p < .005). We found no association between BMD and fracture risk.CONCLUSION:
We confirm that AN is associated with low BMD, whereas BN is not. Remission is associated with higher BMD compared to patients with active AN, but a deficit remains. We found no significant association between BMD and fracture risk, challenging the benefit of the widespread use of DXA scans in young women with ED. CLINICAL TRIAL REGISTRATION The study is registered in ClinicalTrials.gov, number NCT00267228.Palavras-chave
