 The study provides a global overview of the double burden of malnutrition among school-aged children and adolescents, 5 to 19 years, in seven UNICEF-defined regions, highlighting the persistence of stunting, thinness, anemia, and micronutrient deficiencies alongside rising overweight and obesity prevalence. The study suggests that providing multiple micronutrient fortified foods or beverages at school may effectively target micronutrient deficiencies and facilitate weight gain in undernourished populations, but interventions to prevent or manage overweight and obesity are limited. The study calls for consensus on methods for assessing nutritional status and its determinants for this age group, as well as strategies to ensure that nutritious, safe, sustainable diets are available, affordable, and appealing.
