Nutrition problems of hospitalised children in a developing country: Thailand.

Nutritional assessment reveals the nutritional status of a patient. It thereby helps identify each patient's need for specific nutritional care and facilitates early intervention. Generally, the common nutrition and nutrition-related problems in hospitalised paediatric patients are: protein energy malnutrition in various degrees; vitamin deficiencies such as A, B1, B2, niacin, folic acid, K and E; mineral deficiencies such as Zn, Fe, Ca, Mg, P, K and Na; essential fatty acid deficiencies; carbohydrate intolerance; maldigestion and malabsorption; and overweight and obesity. However, there is limited information about nutritional status of hospitalised patients in some countries, especially in developing countries. In Thailand, it was found that the prevalence of hospital malnutrition in children aged 1-15 years in the paediatric ward was similar (50-60%) to that of a study conducted 10 years earlier. In another study of micronutrients in 45 paediatric AIDS patients (aged 3-46 months), high prevalences of malnutrition, anaemia and mineral deficiencies were found. For convenience in clinical practice, body mass index (BMI) values for use as an indicator in the assessment of undernutrition in children whose heights are less than 145 cm have been published. These BMI values have been tested and retested using normal children and patients with various degrees of undernutrition and were found to be reliable and valid. Therefore, nutritional status must be assessed in all hospitalised patients. At the very least, weight and height (length) should be obtained.
