Abstract

Introduction: In Côte d'Ivoire, there is an imbalance between the dietary intake and the nutritional requirements of school-aged children. The objective of this study was to analyze the effect of food diversification, namely sweet potato, soya and cowpea, on vitamin A, D and E profiles among school-aged children in Côte d'Ivoire.

Methodology: This study was conducted over eight months (from October 2017 to May 2018). It included 240 school-aged children (6 - 12 years old) who were divided into four groups of 60 pupils. These children consumed food at school canteens in 12 localities of the Nawa region. Four types of meals were proposed: rice with fish (Group 1 control), sweet potato porridge accompanied by green soybean (Group 2), sweet potato porridge accompanied by white cowpea (Group 3), and sweet potato porridge accompanied by cowpea with soya balls (Group 4). Three blood samples were collected: Phase 0 (prior to the consumption of the meals), Phase 1 (sampling taken three months later) and Phase 2 (sampling taken six months later). Blood assay for vitamins A, D and E was performed using high performance liquid chromatography (HPLC).

Results: Before the children consumed food at the canteen (phase 0), a sufficient amount of vitamins A, D and E was observed, except for group 4 where a deficiency of vitamin D (<30 ng/mL) was noted. The levels of vitamins A and D decreased in groups 1, 2 and 3 from phase 0 to phase 2. However, they increased in children of group 4 from 0.5 to 0.8 mg/L and from 22 to 28 ng/mL respectively. The vitamin E level increased in all groups from phase 0 to phase 2. The improvement in vitamin E status was more remarkable in the children of group 2 and group 4 with levels varying from 8.5 to 11.8 mg/L and 8.3 to 10.6 mg/L respectively.

Conclusion: Improvements in vitamin A, D, and E status were more pronounced in children who ate sweet potato, soybean, and cowpea meal compared to their mean concentration at the beginning of the study. The sweet potato, soybean, and cowpea-based meal could be chosen as a means of food diversification in school canteens in order to improve the vitamin status of school-aged children.
