Brief Summary: Cassavita II study is a Randomized Control Feeding Trial primarily aimed at establishing a proof-of-principle of the efficacy of biofortified yellow cassava in contributing to total retinol pools in 176 children between the ages of 3-5 years, living in a rural area. It is a collaborative project between the University of Ibadan and Wageningen University, Netherlands, funded by HarvestPlus. Field work has been completed, while laboratory analyses of blood and food samples are currently being carried out.

Brief Summary: This is a methodological study aimed at validating the use of a short protocol for assessing body retinol pools in preschool children, by modelling data derived by retinol isotope dilution method. A secondary aim is to compare body retinol pools between children with and without inflammation and to assess the effect of malaria on model parameters. The study forms part of a series of studies commissioned by the International Atomic Energy Agency, with the aim of optimising nuclear techniques to assess vitamin A status in children. Preliminary activities such as ethical approval application, community engagement and recruitment of study participants are ongoing.

Brief Summary: An understanding of the scale and scope of micronutrient status and intake is imperative in prioritizing public health strategies in Africa. However, most African countries lack nationally representative and up to date data on micronutrient deficiency. This study is a systematic review to determine the deficiency prevalence and intake gap of iron, vitamin A, iodine and zinc in children and adolescents (0-18y) in four large African countries, including Ethiopia, Kenya, Nigeria and South Africa.
