1. Malnutrition and child survival Prof Dr. Patrick Kolsteren Nutrition and Child Health Unit Institute of Tropical Medicine Antwerp

2. Malnutrition and mortality Malnutrition is the underlying cause of 3.5 million deaths 35 % of the disease burden in children under five due to malnutrition 11 % of the total mortality and disability

3. Major Causes of Death among Children around the World Deaths associated with undernutrition 60% Sources: EIP/WHO, Caulfield LE, Black RE. Year 2000

5. Expression of malnutrition Thinness or acute severe/ moderate malnutrition Sub-optimal growth: stunting or short stature Micronutrient deficiencies –Vitamin A –Zinc –Iron –Iodine

6. Stunting Lancet series maternal and child nutrition 19 January 2008

7. Vitamin A deficiency Lancet series maternal and child nutrition 19 January 2008

8. Zinc deficiency Lancet series maternal and child nutrition 19 January 2008

9. Health effects Decreased immunity “nutritional immune deficiency syndrome” Frequent infections Psycho-motor development delays School performance Lower IQ Blindness Neurological malformations Short adults pregnancy complications

11. Immediate causes of malnutrition Low birth weight / maternal nutrition No breastfeeding or non exclusive breastfeeding Complementary feeding: –Low quantity –Low energy density –Low quality: diversity, fruit and vegetables Low quality diet : family dish Micronutrient deficiencies Infection pressure

12. DANGERS WITH COMPLEMENTARY FOODS 1.Diarrhea 2.Food allergies and atopic (in particular before 4 months of age) 3.Not enough: - Composition (Fat = 40 %) - Poor density (150 CC /meal ) - Time and frequency 4.Too salty

13. DANGERS WITH COMPLEMENTARY FOODS 5. Low quality - Poor in micronutrients - Low-bioavailability - Low fat :ADEK - Little variation -Qualilty of proteins ( 2/3 cereals and 1/3 tubers) cereals are rich in lysine, poor in methionine and cysteine) - No fruits and vegetables -No animal protein

16. DANGERS WITH COMPLEMENTARY FOODS 6.Contamination Mycotoxine: aflatoxine and fumonisins Little research : In tanzania 20 % of infant in the Kilimanjaro region have intakes above the recommended safety levels. Large seasonal variation. CF is largely cereal based.

21. Infection pressure Drop in maternal immunological protection at 6 months Environmental sanitation : –Diarrhoea –Worm infections –Parasites : vector borne diseases (malaria) Cause of malnutrition and a result of malnutrition

22. What works? Promotion of exclusive breastfeeding Improve complementary feeding and nutrition support Hand-washing and hygiene interventions

23. How to improve complementary feeding? Food based approach: food diversity, accept new food sources in CF Increase fat content Role of ω3 and ω6 fatty acids is not clear. Invest in toxine analyses

24. What works ? Treatment of malnutrition, severe and moderate Focus on identification of malnourished children Vitamin A fortification Iodisation of salt Zinc supplementation Improve maternal nutritional status pregnancy

25. How to get there in operational terms? Coverage means access to infrastructures Infrastructures exist : health care system Most interventions can be delivered through health system if they focus on child health Health systems needs to be supported with a particular emphasis on child health and health promotion

26. Way forward Accept that we know what to do Focus on what works and increase coverage Use existing structures Find ways to deliver the interventions in a local context. Support local initiatives in research and development. Who drives the agenda??? 99 % grants for “new solutions” that can reduce mortality by 22% 1 % for solutions that increase coverage that can reduce mortality by 66 %
