ObjectiveTo investigate the diet and nutritional status of hospitalized children with blood disease in order to provide nutritional guidelines. MethodsThe patients′ daily dietary intakes, including breakfast, lunch, dinner and additional meals, were recorded in detail for seven consecutive days. The intake amount of various nutrients was calculated using the dietary database.ResultsThe majority of children with blood disease showed inadequate intakes of calories［mean 1 825.81 kCal/d, 73.62% of the recommended intake (RNI)］ and protein (mean 67.68 g/d, 81.34% of RNI). Intakes of vitamin E and riboflavin were adequate, but intakes of vitamin A, thiamine and vitamin C (66.67%, 77.78% and 69.89% of RNI, respectively) were inadequate. Iron and selenium intakes were adequate, but calcium and zinc intakes (41.11% and 56.21% of RNI, respectively) were grossly inadequate.ConclusionsHospitalized children with blood disease had decreased dietary intakes of calories, protein, vitamin A, vitamin C, thiamin, calcium and zinc. The dietary pattern and nutritional intake need to be improved.
