Role: Co- Investigator

(b) In progress

  1. Efficacy of bio-fortified (yellow) cassava in improving vitamin A status in children between the ages of 3 – 5 years (CASSAVITA II study).

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.

Role: Co- Investigator

        2. Assessing model parameters for applying the retinol isotope dilution method in preschool Nigerian children living in an area with a high malaria burden (SUPERKID study).

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.

Role: Principal Investigator

         3. Prevalence of iron, vitamin A, iodine and zinc deficiency and intake gap in children and adolescents in African Countries: Ethiopia, Kenya, Nigeria and South Africa

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.

Areas of focus

My core research interest is Community Nutrition with a focus on the nutritional well-being of people in various communities, across the lifecycle from infancy to old age. I also embrace research that employs food science as a means of achieving nutrition security in both rural and urban communities.

My research is built around three interrelated themes:

1. Childhood undernutrition: This aspect of my scholarship has been motivated and shaped by the malnutrition profile of children under the age of 5 years in Nigeria. My studies fall within the purview of capturing and understanding the nutritional vulnerability of children, as shown in papers 4, 13, 18, 20, 22, 32, 33. The findings confirm the high burden of childhood undernutrition in communities, with the biological and social vulnerability varying widely in different contexts. Recommended feeding in this age group is optimal breastfeeding and complementary feeding - recognized globally as the bedrocks of growth and development. These, therefore, form an important sub-set of my studies (papers 6, 8, 23, 25, 27, 28, 29, 30, 31). My research on breastfeeding knowledge seeks to provide critical insights that could serve as a basis for fashioning strategies to improve the breastfeeding in Nigeria. I have investigated breastfeeding awareness and knowledge among various groups in the community including women of reproductive age, health workers, fathers, grandmothers, future mothers - adolescent girls and young brides – not leaving out socially vulnerable groups like out-of-school apprentice girls and girls with physical disabilities. Regarding complementary feeding, my papers have explored the combination and utilization of local food staples to support complementary feeding in childhood. The findings from all the foregoing provide the springboard for my current and future intervention studies on child feeding and undernutrition in children.

2. Food analysis: Food analysis is at the centre of papers 5, 7, 8, 12, 15, 17, 19, 21, 30, investigating nutrient and anti-nutrient composition, as well as functional and sensory properties of local staples and their various mixtures. With soybeans as the connecting thread of interest in most of these papers (as a nutrient-rich legume), this section of my research investigates the potentials of producing nutritious diets from soybeans, cowpeas, maize, crayfish, yam and rice using simple methods that can be adopted at the household and community levels. These papers have contributed to the literature on the improvement of macro- and micronutrient quality of starchy staple diets that are widely consumed.

3. Micronutrient deficiencies: In the community, micronutrient deficiency is a problem across the life course. My early research activities in this area (papers 9, 11, 14, 16) were carried out in South Africa and examined the prevalence of deficiencies and dietary intake gap of zinc, iron, vitamin A and vitamin E in children and the elderly in poor communities. The findings largely indicated low measures of biochemical indicators of micronutrient status, with large proportion of children and elderly failing to meet the recommended intake of these micronutrients. At present, my research effort in micronutrients is growing towards the linkages between agriculture, nutrition and food science, by my recent participation in a randomized control trial to test the efficacy of biofortified cassava in reducing vitamin A deficiency in young children in Nigeria. Although this is work in progress, the indications are that biofortification of staples presents unique opportunities for micronutrient nutrition, and more of these need to be unearthed by research.

In conclusion, the overall aspiration of all my research endeavours, as highlighted above, is to promote optimal nutritional status for the health, improved productivity and development of people especially at the community level.
