Developing countries are the regions whose children are at risk of malnutrition with a high rate of undernutrition and increased statistics of overnutrition leading to obesity. There have been tracked records of increased undernutrition resulting in stunted growth and development. Meanwhile, overnutrition which can lead to obesity is increasing in all age groups, with girls and women being more affected than boys and men. Factors such as low family income, changes in lifestyle, illiteracy among parents, poor environmental conditions, inadequate nutrient intake and poor health conditions predispose children to poor nutrition. Different intervention programmes have been employed to reduce the problem of malnutrition and the most prominent one adopted by government and nongovernmental organizations is the school feeding programme. To reduce malnutrition, there is a need for all stakeholders to painstakingly strengthen policies, create awareness of possible solutions, and constantly evaluate the efficiencies of the intervention programmes. It is only through coordinated efforts that the reduction of malnutrition in developing countries will be reduced. This review, therefore, evaluates the malnutrition intervention programmes among school children in developing countries, especially in Sub-Saharan Africa.
