High Prevalence of IUGR, Stunting and Severe Wasting in Children Under 5
The Vicious Cycle of Malnutrition and Poverty Income poverty Low quality food intake (micronutrients) Frequent infections Physical labor Frequent pregnancies Increased nutrient loss & utilization Malnutrition Low productivity from poor physical performance Loss in productivity from poor cognitive development & schooling Increased health care costs of ill health
Overall and Cause-Specific Mortality Risk for Stunting in Children <5y Old
Together these risk factors are responsible for more than one-third—about 35%—of child deathsand 11% of the global total disease burden The Burden of Maternal and Child Undernutrition

Breastfeeding Maternal Nutrition Nutritional Care of Sick Child Complementary Feeding w/ BF Iodine suppl Vitamin A supplements Control of Anemia Essential Nutrition Actions
Interventions with Sufficient Evidence to Implement in All Countries • Maternal and Birth Outcomes • Iron folate supplementation • Maternal supplements of multiple micronutrients • Maternal iodine through iodization of salt • Maternal calcium supplementation • Interventions to reduce tobacco consumption or indoor air pollution • Newborn Babies • Promotion of breastfeeding (individual and group counseling) • Infants and Children • Promotion of breastfeeding (individual and group counseling) • Behavior change communication for improved complementary feeding • Zinc supplementation • Zinc in management of diarrhea • Vitamin A fortification or supplementation • Universal salt iodization • Handwashing or hygiene interventions • Treatment of SAM
Impact of Community-based Intervention Packages on Initiation of Early Breast-feeding Source: Lassi ZS, Haider BA, Bhutta ZA. Community-based intervention packages for reducing maternal and neonatal morbidity and mortality and improving neonatal. Cochrane Database of Systematic Reviews 2010
Individual vs Group Counseling (EBF rates at 6 months) 38% increase (22-56%) 67% increase (23-126%)
Interventions with Sufficient Evidence to Implement in Specific Situational Contexts • Maternal and Birth Outcomes • Maternal supplements of balanced energy and protein • Maternal iodine supplements • Maternal deworming in pregnancy • Intermittent preventative treatment for malaria • Insecticide-treated bednets • Newborn Babies • Neonatal vitamin A supplementation • Delayed cord clamping • Infants and Children • Conditional cash transfer programs (with nutritional education) • Deworming • Iron fortification and supplementation programs • Insecticide-treated bednets
Local production of ready-to-use therapeutic foods offers great promise

Priority Action Areas • Link maternal and infant nutrition • Scale up orphan interventions (Balanced Energy Protein supplementation for women of reproductive age, Complementary Feeding support in food insecure populations) • Community delivery platforms for nutrition • Link preconception care to nutrition • Adolescent nutrition • Folic acid fortification
