Childhood malnutrition affects growth and development, increases susceptibility to nutrition-related complications and increases healthcare costs⁽Reference Brotherton, Simmonds and Stroud¹⁾. Different methods have been used to assess nutritional status in children admitted to hospital and there is no agreement as to which is best⁽Reference McCarthy, McNutly and Dixon^2–Reference Waterlow⁵⁾. Current data on prevalence of malnutrition (undernutrition and overnutrition) in children with spinal cord injuries (SCI) are limited. The aim of this study was to determine the prevalence of malnutrition in paediatric/adolescent patients with SCI. Undernutrition was defined from the weight for height criteria recommended by Waterlow⁽Reference Waterlow⁵⁾ (normal: >90%; mild undernutrition: 81–90%; moderate undernutrition: 70–80%; severe undernutrition: <70%). Overnutrition was defined by using BMI centile chart (overweight: >91st centile, obese: >98th centile). After obtaining ethics approval, data for weight and height were sought in fifty-three children with SCI (mean age: 11.1 years (sd): 4.8; median: 12.0 years, range: 1.0–17.9 years, 41.5% female) consecutively admitted to the National Spinal Injuries Centre, Stoke Mandeville Hospital, UK from January to August 2010. On admission, weight for height was obtained in forty children [measured weight (47, 88.6%) and estimated height (40, 75.5%)]. The most common causes of SCI were non-traumatic (21, 52.5%) followed by road traffic accidents (16, 40.0%), sports injuries (2, 5%), falls (1, 2.5%) and assault (1, 2.5%). Eight (20%) of these children were at risk of undernutrition (weight for height <90%), two (5%) were at moderate risk of undernutrition (weight for height 80–90%) and two (5%) were at high risk of undernutrition (weight for height <70%). Nineteen (47.5%) were overweight and eleven (27.5%) were obese. Only one in three (33.3%) of the patients at risk (26.3%: overnutrition; 50%: undernutrition) were referred for nutritional intervention. A very high prevalence of malnutrition was found in this group of patients, suggesting that children with neuro-disabilities (SCI) are vulnerable to malnutrition. Given the adverse consequences for short- and long-term health and well-being a valid and practical tool for nutritional screening is needed in this high risk group. Closer scrutiny of the existing but unvalidated paediatric nutrition-screening tool is therefore being conducted with a larger sample size.
