On nutritional assessment scales, under-five children are one of the most vulnerable groups in India. Almost fifty percent of India’s under-five children are underweight which is affecting overall health indicators of India. In this alarming situation, it is imperative to understand the nutritional status and total energy requirement of under-five children in time bound manner for better policy implications. A cross sectional study was conducted among 248 (124 boys and 124 girls) under-five children of seven anganwadi centre of Korba Block of Chhattisgarh using certain anthropometric measurements. The nutritional status and Total Energy Requirement (TER) was determined through the Body Mass Index (BMI)-for-age reference of WHO child growth standard (2006) and FAO/WHO/UNU (2004) equation. Variation in nutritional status and TER was calculated through Pearson chi-square and one-way ANOVA test respectively. Further, Pearson correlation (r) test was applied to check the relationship between them. The age-sex combined prevalence of undernutrition, normal and overweight was 37.5%, 54.8% and 7.7% respectively but found no age-sex variation (χ 2 = 9.27; df = 8; P >0.05). The mean total energy requirement of underweight, normal and overweight children was 871.68 Kcal, 930.31 Kcal and 896.13 Kcal per day respectively and again there was no significant (F= 2.04; P>0.05) difference found between them. The significant correlation was found between total energy requirement with height (r = 0.92; P< 0.01), weight (r = 0.96; P< 0.01) and mid upper arm circumference (r = 0.41; P< 0.01). Major findings point out prevalence of undernutrition in 37.5 % of studied children population. The study suggests for conducting a screening that monitor total energy requirement of under-five tribal children in order to assess the impact of energy requirement on nutritional status.
