The World Bank Group and the World Health Organization, UNICEF in 2015 released Levels and Trends in Child Malnutrition, a review of global trends from 1990 through 2014. It found that stunting prevalence had fallen from 39.6 per cent to 23.8 per cent globally but that the total number of children affected by stunting in Africa had risen. Globally, an estimated 159 million children under age 5 suffered from stunting due to chronic malnutrition and 50 million from wasting due to acute malnutrition. Accentuating the role of inequity, low-income countries made the least progress in stunting reduction, and almost all children under age 5 who experienced wasting were in Africa or Asia.
