Kwashiorkor malnutrition affects hundreds of thousands of children and kills tens of thousands each year. Although recognized as a unique form of malnutrition since the 1930s, its etiology is still unclear. In 1968, a group of scientists studying and treating kwashiorkor met to discuss differences between kwashiorkor and wasting, leading to the diagnostic criteria currently used in treatment and study designs. Over the past 50 years, we have learned a lot more about the progression of kwashiorkor. Through a series of webinars, researchers and practitioners will review recent evidence related to kwashiorkor. These webinars will lead to an expert meeting to discuss and advance kwashiorkor prevention, diagnosis, and treatment. The first round of webinars took place in late September, October, and November 2020. You can find information about these events and recordings here. We are currently planning more events. Please stay tuned. The series is organized by Action Against Hunger UK, Feinstein International Center at Tufts University, and Wageningen University.
