Malnutrition remains a widespread issue in many developing nations, affecting 26% of children globally with stunted growth and nearly 7% experiencing severe wasting, contributing to 55% of deaths in children under 58 due to being underweight. Southern Asia and sub-Saharan Africa are particularly affected. Effectively managing severe acute malnutrition (SAM) is challenging in healthcare settings with limited resources, emphasizing the need for more efficient prevention and treatment strategies. The coexistence of undernutrition and overnutrition, known as the double burden of malnutrition (DBM), adds complexity, emphasizing the necessity for context-specific interventions. In low- and middle-income countries (LMICs), the interplay between early undernutrition and later overnutrition amplifies the risk of noncommunicable diseases (NCDs). Rapid weight gain and linear growth in children in LMICs, while beneficial for survival and cognitive development, may also increase the risk of obesity and cardiometabolic diseases in later life, especially after the age of two. Addressing these challenges urgently requires innovative solutions and effective preventive measures.
