3 The percentage of under five mortality worldwide caused in part by protein energy malnutrition is estimated at: a) 30% b) 20% c) 60% d) 5% 24% 66% 10% 0% a) b) c) d)

4 Definitions

5 Millennium Development Goals (MDG) 2000 United Nations 1. Eradicate extreme poverty & hunger 2. Achieve universal primary education 3. Promote gender equality and empower women 4. Reduce child mortality 5. Improve maternal health 6. Combat HIV/AIDS, malaria, other diseases 7. Ensure environmental sustainability 8. Develop a global partnership for development

6 Define: PEM Underweight: weight for age < 80% expected Marasmus: weight for age < 60% expected Kwashiorkor: weight for age < 80% + edema Marasmic kwashiorkor: wt/age <60% + edema Wasting: weight for height Stunting: height for age SAM: severe acute malnutrition

7 Underweight Define: weight-for-age less 80% expected Encompasses both wasting and stunting Most global data High correlation with stunting Prevalence directly describes the magnitude of the problem of growth faltering and stunting in young children 130 million children under the age of five years

8 Marasmus Weight for age < 60% expected No edema Often stunted Hungry, relatively easier to feed CFR=20-30%

9 Kwashiorkor (Edematous Malnutrition) Underweight with edema Irritable, difficult to feed Electrolyte abnormalities Highest mortality 50 to 60%

10 STUNTING Height for age less than 90% expected

11 Severe Acute Malnutrition SAM Weight-for-height of 70% (extreme wasting) Presence of bilateral pitting edema of nutritional origin, edematous malnutrition Mid-upper-arm circumference of less than 110 mm in children age 1-5 years old

12 Complications of SAM include: A. ARI B. Diarrhea C. Gram negative septicemia D. Poor feeding E. Electrolyte abnormalities F. All of the above 97% 0% 0% 0% 1% 2% A. B. C. D. E. F.

13 Complications of SAM ARI Diarrhea Gram negative septicemia Poor feeding Electrolyte abnormalities

14 TREATMENT of Undernutrition Varies depending on the type of malnutrition Immediate cause: lack of food, lack of appropriate foods for age, lack of protein, maternal death, acute or chronic infection. Resources available Management protocols capable of reducing CFR to 1 to 5%

15 The first step in the treatment of SAM is to prevent and/or treat hypoglycemia. A. True B. False 79% 21% A. B.

16 Ten Steps to Recovery in Malnourished Children Ashworth A, Jackson A, Khanum S & Schofield C 1996 THE WHO TEN STEPS

17 Steps 1 and 2 1. Prevent/treat HYPOGLYCEMIA 2. Prevent/treat HYPOTHERMIA KEY is frequent feeding every two hrs night/day Skin to skin contact with parent, warm lamp, warm blanket, avoid exposure

18 STEP 3 Treat/prevent dehydration 1. Give ReSoMaL or comparable oral solution. 2. Do not use the standard WHO oral rehydration salts solution. It contains too much sodium and too little potassium for severely malnourished children. 3. Do not use the IV route except in shock, and then do so with care to avoid flooding the circulation and overloading the heart. 4. Feed through diarrhea, continue breast feeding

19 STEP 4 CORRECT ELECTROLYTE IMBALANCES * Excessive Na * Deficient potassium * Deficient magnesium Remember: Two weeks minimum to correct Prepare meals w/o salt Do NOT use a diuretic to treat edema

20 STEP 5 TREAT INFECTION Give to ALL severely malnourished children broad-spectrum antibiotic measles vaccine to all children > 6 months. Vitamin A Mebendazole 100 mg BID x 3 days Consider HIV and TB

21 STEP 6 CORRECT MICRONUTRIENT DEFICIENCIES All severely malnourished children have vitamin and mineral deficiencies. Recommend: Zinc, copper and MV daily Vitamin A and folic acid on Day 1 Do NOT give iron until the child has a good appetite and starts gaining weight (usually during the second week of treatment).

22 STEP 7 Cautious Feeding Powdered milk, sugar and oil May include electrolyte/mineral solution Day 1 7 Low in protein and iron, high in energy Small, frequent feeds: 130ml/kg div q2

23 Step 8 Rebuild Tissues Second week Advance to 200 ml/kg/day div q 3 to 4 hours Advance to local foods peanut butter, beans, margarine energy dense local foods

24 STEP 9 Stimulation, Play and Loving Care tender, loving care structured play and physical activity as soon as the child is well enough a cheerful, stimulating environment. Encourage mother s involvement 90% expected weight for height ready for discharge

25 Nutritional education Immunization Home Follow Up STEP 10 Preparation for Discharge

26 Treatment of Malnutrition PHASE STABILISATION REHABILITATION 1. Hypoglycaemia 2. Hypothermia 3. Dehydration 4. Electrolytes 5. Infection 6. Micronutrients 7. Cautious feeding 8. Rebuild tissues 9. Sensory stimulation 10. Prepare for follow-up Day 1-2 Day 2-7+ Week 2-6 no iron with iron

27 Direct causes of death: 1. Hypoglycemia 2. Hypothermia 3. Dehydration 4. Infection 5. Severe anemia Time Magazine, August, 2008

28 Outpatient management Malawi, Sudan, Ethiopia ,511 severely malnourished children 74% treated solely as outpatients CFR=4.1% Recovery rates=79.4% Default = 11% Niger, MSF 60,000 children with SAM 70% outpatient CFR=5% Lancet, 2006
