May enhance leptin assessment in eating disorders beyond BMI; leaves open prospective validation before clinical adoption.
Observational (n=40)
In female inpatients with eating disorders, percentage body fat measured by DXA is a better predictor of serum leptin levels than BMI.
Mathiak et al. (1999) conducted an observational in Anorexia or Bulimia Nervosa (n=40). Percentage body fat vs. Body mass index (BMI) was evaluated on Predictor for leptin level and clinical findings. Percentage body fat measured by DXA was a better predictor for serum leptin levels and clinical findings in eating disordered patients than BMI.
