Evaluation of Dietary Diversity, Nutrient Adequacy and Nutritional Status of Pre-school Children in Three Local Government Areas of Ibadan, Nigeria

Malnutrition remains a public health challenge in Nigeria, partly due to poor diversity of diets. Pre-school children are among the vulnerable groups who are mostly affected in communities, as their nutritional status is largely influenced by the quality of diets they consume. Most studies aimed at malnutrition among under-five children have been focused on meeting protein-energy needs without much consideration for micronutrients needs. Dietary diversity has been advocated as a means of meeting nutritional requirements of children. This study was designed to assess the dietary diversity in relation to nutrient adequacy and nutritional status of pre-school children in Ibadan. The descriptive cross-sectional study was carried out among 552 pre-schoolers aged 3-5 years in Egbeda, Ona-Ara and Ido Three Local Government Areas (LGAs) of Ibadan metropolis. A structured questionnaire was used to obtain information on socio-demographic characteristics of mother and child. Nutritional status was determined using anthropometric indices. Food frequency questionnaire of 9 food groups was used to obtain dietary diversity scores (DDS) classified as low (< 4 food groups), average (4 to 6 food groups), and high (≥ 7 food groups); and 24-hour dietary recall was used to obtain nutrient adequacy of diet. Data were analysed using descriptive statistics, Pearson’s correlation coefficient, and level of significance set at p < 0.05. Malnutrition among pre-schoolers was more prevalent among males (22.0%) than females (18.4%). Stunting was the most prevalent form of malnutrition (26.8%). The DDS of pre-schoolers was low (3.2 ± 1.9). The most consumed food group was cereals, roots and tubers (83.9%) while fruit was least consumed (6.5%). Nutrient adequacy ratio for carbohydrate was highest (1.2 ± 0.2) and least in fibre (0.2 ± 0.2), while mean adequacy ratio for food consumed was (0.72 ± 0.13). There was weak relationship between DDS and nutritional status—wasting (r = -0.067), stunting (r = -0.002) and underweight (r = -0.056). Low dietary diversity and malnutrition existed among pre-school children in the three LGAs. Nutrition education and enlightenment programmes are required by the parents/guardians of pre-school children on importance of dietary diversity in these areas.
