Assessment of protein-energy malnutrition in children with chronic arthritis

Abstract

Protein-energy malnutrition (PEM) has been estimated to occur in 10 to 50% of children with juvenile chronic arthritis (JCA). Thirty-eight children with JCA were evaluated and their nutritional status determined, and they were compared with 23 healthy sex and age-matched children as controls. A standardized, 9-parameter comprehensive nutritional assessment profile was used. The simple anthropometric measurements, height and weight for age, were abnormal in 30% and 27% of the patients, respectively. A detailed evaluation revealed that 71% had abnormal somatic protein stores, and that they also had significantly low levels of visceral protein stores, when compared to their healthy peers. The results were consistent with the fact that inflammation put the JCA patients at significant risk for developing complicated malnutrition and it might result in PEM without any obvious signs of malnutrition. A nutritional screening test would be very useful in detecting early PEM in children with chronic arthritis.
