Abstract
Nutrient intake and nutritional status were assessed in 15 children with juvenile chronic arthritis (JCA) and in 17 healthy controls. Anthropometric measurements were similar in children with pauciarticular JCA and in controls, whereas weight (p = 0.05) and upper arm muscle area (UAMA) (p < 0.01) were reduced in children with polyarticular JCA. Compared with healthy controls the concentrations of hemoglobin, serum iron and serum zinc were reduced in the children with polyarticular JCA (p < 0.01) and serum copper was increased (p < 0.01). In the patients the concentrations of hemoglobin, serum iron and serum zinc correlated negatively with erythrocyte sedimentation rate (ESR), whereas serum copper correlated positively. Impaired nutritional status was found in the children with polyarticular JCA in spite of increased energy and protein intake. In this group of patients the dietary intake of calcium was also found to be reduced.
