The paucity of adequate data on dietary and nutrient intakes of school-age children is a barrier to addressing malnutrition and associated risks in Nigeria. This study included 955 children aged 4-13 years from Ibadan, Nigeria, using a stratified random sampling design. Information on family socio-demographic characteristics was reported, and child anthropometrics were measured. Dietary intake data were collected using a multi-pass 24 h dietary recall method; 20% of subjects completed a second 24 h recall to estimate usual nutrient intakes. Means and distributions of usual intakes of energy and nutrients as well as prevalence of inadequacy were estimated. Usual energy intake (kcal/day) was 1345 and 1590 for younger (4-8 years) and older (9-13 years) age groups, respectively. The macronutrient intakes of most children did not conform to Adequate Macronutrient Distribution Ranges (AMDRs), which were characterized by a higher proportion of energy from carbohydrates and lower proportion from total fats. Protein intake was largely within the AMDR. Compared to recommendations, over 60% of 4-8-year-old children had inadequate intakes of calcium, copper, iron, folate, and vitamins A, D, and E. There were more micronutrient inadequacies in the older children. This study identifies nutrition gaps and suggests future research and education to improve child nutrition in Nigeria.
