['We evaluated the role of an interdisciplinary team in improving the nutrient intake and nutritional status of children with heart diseases.', 'Thirty-five children 10.0 +/- 7.5 mo old were studied over a 6-mo period with regard to anthropometric measurements and dietary intake.', 'On admission, malnutrition prevalence was 57% and vitamin and mineral intakes were below estimated average requirement levels (dietary reference intakes) in the majority of patients. Stunting and wasting were more frequent among patients with pulmonary hypertension and/or uncompensated congestive heart failure. Follow-up analyses showed increased Z scores of weight for height (-1.17 +/- 1.03 versus -0.32 +/- 1.08, P < 0.01) and height for age (-1.09 +/- 0.96 versus -0.51 +/- 1.36, P < 0.01). In patients with pulmonary hypertension or uncompensated congestive heart failure, the height-for-age index remained unchanged. Energy intake did not differ (112.0 +/- 20.4 and 119.0 +/- 18.0 kcal.kg(-1).d(-1)) and significant increases were seen in intakes of micronutrients and minerals over the study period.'] Does interdisciplinary approach improve nutritional status of children with heart diseases?
