This article focuses on the factors contributing to increased risk for malnutrition in juvenile rheumatoid arthritis patients, the methods of identifying and treating nutritional problems (including protein-energy malnutrition and obesity), and outlines national statistics demonstrating that the pediatric rheumatic patient population is nutritionally underserved. The dietitian, in conjunction with the interdisciplinary treatment team, should be involved in the initial evaluation of all juvenile rheumatoid arthritis patients to facilitate early detection of nutritional problems and initiate nutritional intervention strategies.
