Improving Iron Status Through Consumption Of Iron Fortified Cowpea: An Intervention Study

Rationale: Iron deficiency and zinc deficiency, are of public health significance in sub-Saharan Africa. An estimated 50% of children (5-14 years) in developing countries suffer from anaemia, half of which is estimated iron deficiency anaemia. Interventions have been designed and implemented over the years towards solving hunger and anaemia especially among school age children. One of such interventions is School Feeding Programme (SFP) which is common in both developing and industrialized countries. SFP has been part of the Ghanaian educational system for well over 40 years, albeit on small scale. The main stay of the programme that makes it distinguishable from other past and existing school feeding programmes is its reliance on locally produced and available foods, such as cowpeas. Legume staples like cowpea have been identified to be important sources of protein and non-heme iron to rural populations of developing countries like Ghana. The problem however is the low bioavailability of these micronutrients from these legumes. Objective: To assess the efficacy of iron fortified cowpea based meal (Tubani) in improving iron status of primary school children in rural northern Ghana Study design: A randomized double blind parallel design will be conducted. One group will receive iron fortified Tubani with NaFeEDTA and the other group will receive unfortified Tubani. Study population: Two hundred and forty apparently healthy pupils in lower primary school will participate. The participating schools have a school feeding programme currently in operation. Intervention (if applicable): Children will be fed Tubani containing 10mg of fortification iron (in the form of NaFeEDTA) three times in a week for six months. Weight, height and blood samples will be measured at baseline and after six months of intervention. Participants will be treated against intestinal parasites before start of intervention and halfway through the intervention. Main study parameters/endpoints: T
