Nutrition therapy is essential to the management of several chronic diseases affecting adolescents. Unfortunately, dietary impositions may evoke pathological eating-related cognitions. This pilot study examined eating- and weight-related cognitions of 55 adolescents attending a summer camp for youngsters with a heterogeneous variety of chronic diseases. Campers completed the Eating Cognitions Questionnaire and the Situational Obstacles to Dietary Adherence questionnaire. Campers whose medical regimens included special dietary recommendations ( n=24) were expected to have more cognitions associated with eating disorders than those without dietary restrictions ( n=31). Girls were significantly more concerned than boys about weight and restrictive dietary rules. Cognitions of youngsters with special dietary recommendations showed greater flexibility, less eating pathology and less weight concern than campers without recommended diets. Contrary to previous reports, dietary restrictions were associated with more appropriate eating cognitions, suggesting that adolescents with chronic illnesses requiring nutrition therapy may not necessarily bear greater risk of eating disorders.
