Prevalence and predictors of under-nutrition among school children in a rural South-eastern Nigerian community: a cross sectional study

Abstract

BackgroundSchool children in developing countries like Nigeria are faced with numerous nutrition and health problems. Lack of functional school health and nutrition programmes in Enugu state, Nigeria may be associated with dearth of data on associated factors. Identifying these factors could inform the design and implementation of school-based programmes aimed at ameliorating these problems.MethodsA cross sectional survey involving 450 primary and secondary school children aged 6–15 years was conducted in Ede-Oballa, a rural community in Enugu state, South-eastern Nigeria. Selection of the pupils was by multistage sampling technique. Data were collected through interviewer administered questionnaire, anthropometric measurements of weight and height, 3-day weighed food intake, stool microscopy and blood analyses for malaria, zinc and vitamin A. Bivariate and multivariate logistic regression analyses were used to evaluate associations of interest with significance accepted at P < 0.05.ResultsThe school children were affected by underweight (18.2%), stunting (41.6%), thinness (20.0%), zinc (43.3%) and vitamin A (51.1%) deficiencies. After adjusting for potential confounders, weekly food expenditure was a major predictor of under-weight (AOR = 0.19, 95% CI: 0.08, 0.46), stunting (AOR = 0.36, 95% CI: 0.13, 0.95) and thinness (AOR = 0.49, 95% CI: 0.30, 0.80); household income was also a predictor of thinness (AOR = 0.47, 95% CI: 0.25, 0.88). Males had lower odds of being stunted than females (AOR = 0.31, 95% CI: 0.11, 0.83). The odd of being underweight was higher in female headed households than in households headed by males (AOR = 0.30, 95% CI: 0.12, 0.75). Tapeworm was an independent predictor of vitamin A (AOR = 3.59; 95% CI: 1.06, 12.13) and zinc (AOR = 3.64; 95% CI: 1.02, 12.98) deficiencies. Children with whipworm were more likely to be zinc (AOR = 3.80; 95% CI: 1.11, 13.04) and vitamin A (AOR = 3.79; 95% CI: 1.12, 12.89) deficient than those uninfected.ConclusionUnderweight, stunting, thinness, vitamin A and zinc deficiency among the school children were functions of weekly food expenditure, gender of household head and household income, tapeworm, whipworm, and sex. These findings emphasize the need for effective school- and community-based interventions.

Assessment of Nutritional Status of Rural Primary School Students at Abu-Kbeer District, Sharkia Governorate

“…35.7% took sufficient fruits, 63.9 % took sufficient protein sources, and 94.9% took sufficient carbohydrates. These findings were in agreement with Ayogu et al [20]…”

The double burden of malnutrition in a rural health and demographic surveillance system site in South Africa: a study of primary schoolchildren and their mothers

“…This circumstance suggest that the ability to purchase nutritious food is compromised, which may lead to food unavailability in households and ultimately affect the feeding practices of children, as explained by various researchers [49, 50]. The variations in the prevalence of thinness across and within different countries is explained by differences in their social, demographic, economic, nutritional and cultural contexts [51–53].…”

Health and disease among Somali primary school children in Hargeisa

“…Malnutrition rates were substantial and 25.0% of the children were malnourished. This is a higher prevalence compared to other surveys using BMI-forage among primary and secondary school children in Nigeria (20%), Vietnam (11%) and India (22%) [20][21][22]. The famine and cholera outbreak in the study area in 2017 may have contributed to poor nutrition [23].…”
