Diet quality of adolescents with eating disorders

Abstract

Purpose To compare the nutritional intake of adolescents with eating disorders (EDs) to recommended Daily Values of macronutrients and micronutrients, using the Nutrition Data Systems for Research (NDSR); to determine if nutritional content varied among the different sub-types of EDs; and to use the Healthy Eating Index 2010 (HEI-2010) as a measurement of diet quality in this population. Methods Forty-six adolescents referred to an ED Program were recruited for inclusion in this study. A detailed 24-h dietary recall from each participant was obtained and a detailed nutritional analysis was generated, allowing for calculation of the HEI-2010. Descriptive statistics were calculated to determine baseline characteristics of the study population and to determine associations and differences between ED subtypes. Results Average daily caloric intake was below recommended values in the study population. Despite this, the distribution of macronutrients was within the ranges recommended for older children and adolescents by the Dietary Guidelines for Americans, 2010. Micronutrient content varied considerably. The study population had a mean HEI-2010 score of 60.1, falling within the "needs improvement" category. A majority of the participants had insufficient caloric intake for the HEI to be applicable. Conclusion Results suggest that adolescents with EDs have a surprisingly normal distribution of macronutrient intake. Although using a diet quality assessment tool such as the HEI-2010 has been helpful in analyzing overall diet quality in the general population, the restrictive caloric intake which characterizes the ED population prevents the utility of such a guide for most patients with EDs.
