Therefore, the primary goal of the current study was to examine the agreement and/or discrepancy between the BMI, McLaren, and Moore methods when calculating EBW for adolescents with eating disorders. In studies of patients with eating disorders, authors rarely describe their method for calculating EBW. 14 However, such calculations are widely discrepant for older healthy adolescents at the lowest and highest percentiles. Researchers have demonstrated considerable agreement for EBW calculations across these 3 methods for healthy adolescents. The BMI, McLaren, and Moore methods are all pediatric specific and use the child or adolescent’s gender, age, and height to calculate EBW but do not take other measures of anthropometry (eg, body composition and body frame) into account. 10, 11 In addition to the BMI method, 9 other methods are used to calculate EBW for example, the McLaren 12 and Moore 13 methods. For pediatric and adolescent populations, age- and gender-adjusted BMI percentiles are more appropriate as weight and height normally increase until 20 years of age (Centers for Disease Control and Prevention BMI-for-age growth charts 9Įxamination of an adolescent’s weight in relation to the 50th BMI percentile, also known as the BMI percentile method, or BMI method, is perhaps the most frequently used method to determine the weight criterion for an eating disorder diagnosis. 8 Therefore, it is not an optimal method to reflect nutritional status, especially for adolescents. 6, 7 Moreover, BMI is based on height and weight only and does not account for unique phenomenon such as short stature or stunted linear growth due to malnutrition. Although absolute BMI (weight in kilograms/height in meters see ref 2) has gained attention in both clinical and research settings, it is most commonly used to screen for obesity and is most applicable to the adult population. 4, 5 Yet, there is no consensus on how best to calculate EBW for the pediatric and adolescent eating disorders population. In addition to diagnosis, EBW is used as an indicator of medical stability, as justification for hospitalization, to set appropriate target weights, 2, 3 and to track progress in treatment and assess recovery.

Determining the deviation from expected body weight (EBW) (often referred to as “ideal” body weight) is therefore important in the diagnosis of AN (85% EBW) and eating disorder not otherwise specified (deviation from EBW less clearly demarcated). 1 This preoccupation is often manifested by an inability to maintain a normal weight for age and height and is the primary diagnostic criterion for anorexia nervosa (AN). A commonly agreed upon method for EBW calculation such as the BMI percentile method is recommended for clinical and research purposes.Įating disorders are characterized by disturbances in ingestive behavior and are usually accompanied by preoccupation with weight and shape. Well, also the adults will get precise body mass index (BMI) information according to original BMI formula for adults over 21 years.The McLaren and Moore methods present with several limitations when calculating EBW for adolescents with eating disorders.
