Fig. 1From: Optima Nutrition: an allocative efficiency tool to reduce childhood stunting by better targeting of nutrition-related interventionsDiagram of the Optima Nutrition model. The number of children under 5Â years is tracked across five age bands. Children enter the model by birth: term or pre-term, small for gestational age (SGA) or average for gestational age (AGA). Children leave the model either by reaching 5Â years of age, or by death. Risk factors which affect stunting and mortality, and interventions included in the model to reduce mortality and stunting, are shownBack to article page
