Abstract
This cross sectional study was carried out to compare the nutritional status of public primary school children in an upland and a riverine area of Ojo Local Government Area of Lagos State, Nigeria. A multistage sampling method was used to select a total of 240 children, 120 from each of the two areas. The study population for each area had an equal sex distribution (60 boys and 60 girls). Dietary, anthropometric, clinical and laboratory methods were employed.
Using the National Centre for Health Statistics (NCHS/WHO) Reference values, a malnutrition prevalence of 20.8 and 30.81 for the upland and riverine populations respectively was found. There was a stunting in 15.8% of upland and 30.0% of riverine children; 3.3% and 1.7% of them were wasted, and 14.2% in the upland and 18.3% in the rural area were underweight. The mean weights and heights for boys and girls of different ages were lower for the riverine group, although no statistically significant differences were found. Anaemia occurred among 25.0% and 29.2% of the upland and riverine groups respectively. Intestinal helminth infection was found to be significantly associated with malnutrition. Ascaris had a prevalence of 46.7% in the upland and 63.3% in the riverine area. Trichuris had a prevalence of 15.0% and 19.2% in the upland and riverine area respectively. To address the malnutrition problem in these populations, efforts should be aimed at increasing food availability and quality, personal and environmental hygiene, supply of basic amenities, prevention and treatment of infection, and general living conditions of these populations.
