Albumin and pre-albumin levels do not reflect the nutritional status of female adolescents with restrictive eating disorders

Abstract

Aim Albumin and pre-albumin are frequently used as nutritional markers in clinical practice. We examined whether serum albumin and pre-albumin were predicted by body mass index (BMI), hydration and/or inflammation in female adolescents with a recently diagnosed restrictive eating disorder (RED). Methods This was a retrospective study of female adolescents with RED from 2002 to 2011. Low albumin and pre-albumin levels were defined as <3.5 g/dL and <20 mg/dL, respectively. We assessed inflammation using the erythrocyte sedimentation rate (ESR) and dehydration using the haematocrit levels. Results We included 75 females with a mean age of 15.2 years and 64% had a BMI Z score of
