Effect of African Leafy Vegetables on Nutritional Status of South African

Status Completed

Clinical Trial Summary

The combination of poverty-related infectious and lifestyle-related non-communicable diseases, both driven by malnutrition, causes a high burden for South Africa. Healthy and nutritious diets for populations depend on availability and accessibility of a variety of plant and animal foods, within a context that promotes and supports healthy behaviour. Food based strategies, such as supplementation, food fortification, and diversification of crops, are used to achieve optimal dietary requirements to combat malnutrition, including micronutrient deficiencies. A more sustainable food based strategy is the (promotion of) use of indigenous and traditional foods, such as African Leafy Vegetables (ALVs). Unfortunately, several studies from all over Africa have shown that there is a shift from traditional diets as result of the preparing techniques and the absence of women in homes. Furthermore, indigenous and traditional foods are considered as "poor people's food".

Against this background, a joint project between South Africa, Kenya and Benin is designed to fill the gaps in knowledge in these countries regarding the availability, acceptability and consumption and evidenced based benefits of foods from local biodiversity. The main aim of the study in South Africa is to provide empirical evidence of how the role of biodiversity can be translated into improved health status in contemporary poor rural and urban communities in the North West Province of South Africa. In order to achieve this it is important to gain knowledge on the possibility of using ALVs as a strategy to alleviate micronutrient deficiencies. Therefore an intervention study to determine the effect of selected ALV on the nutritional status (including zinc, iron, and vitamin A status) of school children (grade R-4) residing in contemporary poor rural community in the North West Province, South Africa has been designed.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
