Prediction of Nutritional Status by Chemical Analysis of Urine and Anthropometric Methods

A combination of anthropometric and chemical indices was used to investigate the nutritional status of 26 healthy (H) and kwashiorkor (K) children aged 2–5 years and possibly predict the onset of malnutrition. The healthy children had significantly (p > 0.05) higher values for weight, height, middle upper arm circumference and weight/height ratio than kwashiorkor children. The healthy children had significantly higher urinary concentrations of urea, inorganic sulphate and sulphate relative to creatinine, but significantly lower thiocyanate and thiocyanate relative to creatinine than the kwashiorkor children. The results of the present study would tend to indicate that a chemical analysis especially of urea, inorganic sulphate or thiocyanate alone or the ureal creatinine, inorganic sulphate/creatinine or thiocynate/creatinine ratio could be used to predict malnutrition after the initial anthropometric measurements. This study should however be repeated with a large population of volunteers to determine the specific cut-off points for each anthropometric and chemical analysis.
