heterogenous results. It is estimated that education interventions, if optimally designed and implemented, could reduce stunting by 0.6 z-scores while food-based interventions could reduce stunting by 0.5 z-scores, which is moderate compared to the average global growth deficit. Finally, the Lancet-series on maternal and child nutrition estimated that the impact of all existing interventions designed to improve nutrition and prevent related diseases in mothers and children, could reduce stunting at 3 years by merely 36%. Hence, factors explaining the shortfall in observed associations between child feeding practices and nutrient intake and linear growth, have increasingly been the focus of scientific interest. Recent works showed promise that intervention with egg may improve linear growth in children. Comprehensive intervention package containing eggs also found to be effective in improving linear growth in children. However, the effect of egg intervention may not persist for longer period. Therefore, intervention programs should consider egg intervention for a longer period with emphasis on overall diet quality and improvement of environmental conditions. Pregnant and lactating mothers Ensuring proper nutrition of pregnant and lactating mothers is essential. Achieving so by helping women of reproductive age be in good nutritional status at conception is an excellent preventive measure. A focus on the pre-conception period has recently been introduced as a complement to the key phase of the 1000 days of pregnancy and first two years of life. An example of this are attempts to control anemia in women of reproductive age. A well-nourished mother is the first step of stunting prevention, decreasing chances of the baby being born of low birth-weight, which is the first risk factor for future malnutrition. Balanced protein–energy supplementation in pregnancy seem to improve birth weight of children, with greater effects in undernourished women. Meanwhile, micronutrient supplements and lipid based nutrient supplements (LNS) (providing both macro-and micronutrients) during pregnancy have shown mixed effects on birth weight and -length. Similarly, studies supplementing LNS to mothers during pregnancy and lactation and their children during the complementary feeding period show heterogeneous results for stunting. After birth, in terms of interventions for the child, early initiation of breastfeeding, together with exclusive breastfeeding for the first 6 months, are pillars of stunting prevention. Introducing proper complementary feeding after 6 months of age together with breastfeeding until age 2 is the next step. Policy interventions In summary, key policy interventions for the prevention of stunting are: Improvement in nutrition surveillance activities
