Abstract Nutritional status affects every aspect of a child?s health. Thorough nutritional assessment is hampered by the lack of a single comprehensive tool, which can cover all aspects of nutritional assessment. In three distinct studies, this thesis investigated the nutritional status of hospitalised children, children with coeliac disease and children with inflammatory bowel disease. Study 1 The objectives of this study were to assess prevalence of malnutrition and nutritional risk, and define demographic and anthropometric factors associated with nutritional risk among hospitalized children. In this cross sectional study, 157 hospitalised children were assessed for nutritional status using nutritional risk score (NRS) and anthropometric measurements. We found that 4.5%, 8.9%, 15.1% and 10.4% children were wasted, stunted, overweight and obese respectively. However, with the NRS, 47.8% of the children were at high nutritional risk. These children at high risk had lower weight for age (p=0.02), lower BMI percentiles for age (p=0.001) and longer hospitalization (p=0.001) than children at no risk. Study 2 The objectives of this study were to determine nutritional parameters in children with coeliac disease. Twenty-five children with coeliac disease and an equal number of age and gender matched controls were enrolled and anthropometric measurements, BIA and leptin levels were analysed in all. No significant differences were found between the children with coeliac disease and controls in these parameters. BMI percentile correlated with leptin levels in children with coeliac disease. Study 3 The objectives of this study were to determine anthropometric parameters and leptin levels in children with IBD and ascertain if BMI correlates with leptin levels in these children. Thirty children with IBD and 60 age and gender matched controls were enrolled. Anthropometric measurements and leptin levels were analysed and compared with controls. IBD children had significantly low weight for age (p=0.002), BMI percentiles (p=0.001) and leptin levels (p=0.009) compared to controls. There was a correlation between BMI and leptin levels in IBD children. In conclusion, this thesis has shown that one quarter of hospitalized children were overweight or obese, and further, that half of the hospitalised children were at high risk of nutritional deterioration and these children had longer hospital stay than children at no risk. Children with coeliac disease had similar anthropometric measurements, body compartments and leptin levels to controls. However, children with IBD had lower anthropometric measurements and leptin levels, indicating under-nutrition. Nutritional assessment should be a mandatory part of clinical management with nutritional status assessed by various tools including NRS, anthropometry, BIA and leptin levels.
