Abstract
Despite the importance of nutrition in childhood health, growth, and development, relatively few high-quality data on usual nutrient intakes among children are collected in sub-Saharan Africa (Ochola and Masibo, Steyn, Eksteen and Senekal). Such data are important for informing researchers and policy makers on areas requiring targeted investigation and public health intervention. When large investments by funders, researchers and participants alike have been made in the collection of dietary data as part of an intervention trial, it is therefore logical and beneficial to analyse all available data and to make the results accessible. A limitation in the use of such data is that convenience samples commonly used in randomised trials are unlikely to be truly representative of the underlying population.
