Geophagia is the most common type of pica, characterized by the urge to consume clay or soil. QwaQwa houses a very dense black African population and covers 254.2 km2. This rural area with the largest concentration of Basotho’s in South Africa is characterized by a strong focus on traditional beliefs and practices, making it a favourable area to investigate the phenomenon of geophagia. The main aim of this study was to determine the nutritional status and risk factors associated with women practicing geophagia in QwaQwa, South Africa. Socio-demographic factors, dietary intake, anthropometry, physical activity and blood measures were investigated at baseline. After the intervention, the impact of the nutrition education on knowledge and habits related to geophagia were determined.
