Emergency Food & Nutrition in Refugee Situations • Objectives • Assessment • Interventions • Nutrient Deficiencies • Surveillance & Monitoring
Refugee CrisesEmergency Phase Top 10 Priorities • 1- Initial Assessment • 2- Measles Immunization • 3- Water & Sanitation • 4- Food & Nutrition • 5- Shelter & Site Planning • 6- Health Care in EM phase • 7- Control of communicable diseases & epidemics • 8- Public health surveillance • 9- Human resources & training • 10- Coordination
Definitions (Wikipedia) • Food security refers to the availability of food & one's access to it. A household is considered food secure when its occupants do not live in hunger or fear of starvation. • Hunger is a feeling experienced when one has a desire to eat. • Malnutrition is the insufficient, excessive or imbalanced consumption of nutrients .
REFUGEE SITUATION • Food & nutritional security threatened • Malnutrition, disease & death • Refugees need partial/full food support (acute phase), +/- nutritional rehabilitation
OBJECTIVES • Objectives of food intervention programmes • Ensure adequate nutritional general food ration (GFR) • 2,100Kcal/person/day→ Prevent malnutrition/mortality • ↓ Prevalence/mortality from malnutrition • Role of health agencies: Rx of malnutrition/nutritional deficits • Selective feeding programmes • Monitor regularity & adequacy of food rations • May take charge of general food distribution
Organization of Food SupportWorld Food Program & UN High Commissioner for Refugees • MOU (WFP & UNHCR) establishes responsibilities & coordination mechanisms for meeting food & nutritional needs of refugees • UNHCR food & nutritional coordinator - responsibility for coordination of all aspects of the program • Refugees (women) must be involved • Nutrition education • Aim of food programs: • Restoration & maintenance of sound nutritional status • Food ration that meets • Assessed requirements • Nutritionally balanced • Palatable & culturally acceptable
ASSESSMENT of Food & Nutritional Situation(part of Initial Health Assessment) • Phase I • Early, quick evaluation → severity of global picture • Need for rapid intervention • Facilitate planning necessary resources • Based on observation, interviews/discussions key informants • Phase II • Quantified data gathered on nutritional situation • Decides type & size of nutritional programs • Prevalence of malnutrition, food available/accessible, factors affecting nutritional status • Expensive, time consuming, not always feasible
Assessment : Basic Information • Numbers & demographics • Current nutritional status • Milling possibilities • Food preferences • Family capacity to prepare, store, process food • Access to fuel, utensils, containers • Local food availability • Present/over time • Local food for purchase • Ease of access • Groups at risk • Who/ how many • Self reliance & coping strategies
Assessment: Other Important Information • Health status & services • Environmental health risks • Community structure • Food distribution systems • Social-economic status • Logistics constraints • Security constraints • Availability of human resources • Storage capacity & quality • Delivery schedule of food & non food commodities • Other agencies activities & assistance provided: • Quantity, items, frequency • Selective feeding programs
Food availability & accessibility • Quantity/quality food (usually insufficient w/out distribution) • Initial data: • Food distribution already taking place • Food ration, frequency of distribution, distribution agency, target group • Assessment of local market • Food basket of individual households (by sample survey) • Food sources often diverse: food aid, shared w/ locals, food purchased/bartered for/ gathered
Nutritional status of refugee population:prevalence of acute malnutrition in U5 yrs age • How to measure malnutrition • W/H index most reliable: reflects present situation, most sensitive to rapid change • Oedema→ severe malnutrition (Kwashiorkor) • MUAC: quick, high variability, rapid assessment tool • Implementation of nutritional survey • Sample of children 6mo-5yrs w/ W/H index • How to express malnutrition rates: Z scores • Global malnutrition: % children <-2 Z scores and/or oedema • Moderate malnutrition: % children < -2 Z scores > 3 Z scores • Severe malnutrition: % children < -3 Z scores and /or oedema
Key Nutritional Indicators • U5Moderate Severe • W/H % of median value 70-79% < 70% • W/H in Z scores -3 to -2 Z < -3 Z (edema) • MUAC 115 - <125 mm < 115 mm (edema) • Adults • BMI (wt in kg)/(ht in m)2 16-17 < 16 • MUAC (pregnant women)
Other information • Contextual factors • Mortality figures • Majors disease outbreaks (measles, cholera, diarrhea, etc) • Micronutrient deficiencies • Housing conditions • Water supply & sanitation • Climate & geography • Customary diet of population • Security situation • Provisions of local health services
Interpretation of results • Essential indicators • Global acute malnutrition rate : 5% common in Africa/Asia, 5-10% should act as warning, > 10% serious • Severe acute malnutrition rate • Bias in estimating severity • Very hi MR among most vulnerable: under estimates malnutrition • Timing & season of the year • Distribution of malnutrition in population • Age grp, date of arrival, ethnic grp, camp section, etc • Helps target programs • Three main contextual factors • Mortality figures • General food rations & food accessibility • Major outbreaks of disease
Planning quantity of food • Based on demographic information & prevalence of malnutrition from nutritional survey • If presumption of major nutritional emergency, assume: • U5: 15-20% of total pop • Pregnant: 1.5-3% of total pop • Lactating: 3-5% of total pop • 15-20% moderate malnutrition • 2-3% severe malnutrition Quantity of Commodity Required= Ration/person/day X no. benef. X no. days
Classical Emergency Food Interventions • General food distribution • Ensure adequate food rations for all • Selective feeding programs • Targeted Supplementary feeding programs (SFP) • Moderately malnourished U5, selected pregnant /nursing women, referrals from TFP, other malnourished people & medically referred • Blanket SFP • Children <3 or 5 yrs age, all pregnant/nursing women, other at risk groups • Therapeutic feeding programs (TFP) • <5yrs severely malnourished, idem other age grps • LBW infants • Unaccompanied minors/orphans <1yr age • Mothers of <1yr infants w/ breastfeeding failure
How to decide on the Intervention • General food ration available • 2,100Kcal/person/day for all refugees • Malnutrition rate • Indicates level of intervention required • Aggravating factors: requiring ↑ level intervention • CMR > 1/10,000 day, ↑ level malnutrition • Inadequate food ration < 2,100Kcal/person/day • Epidemics: measles, cholera, shigella , pertussis, etc • Severe cold & inadequate shelter, ↑ level activity/males • Unstable situation: new influx of refugees • Wastage (grinding, poor storage), losses, ↑ barter for non food items • Other considerations • Vulnerabilities of specific grps, logistical constraints, agencies capacity, security, food basket unfamiliar to refugees, local nutritional status, etc
Responding To CrisisSimplifiedDecision Tool [1] Aggravating factors are: i) General food ration below the mean energy requirement (<2100 kcal/kg/person), ii) Crude Death Rate greater than 1/10 000/day and iii) Epidemic of measles or whooping cough. [2] This may include therapeutic care integrated into primary health system (hospitals and health centres).
Responsibilities & Coordination • WFP • UNHCR • UNICEF • Food aid agencies • Health agencies
Quality of GFR • Minimum 2,100Kcal/per/d • 10-12% protein energy, 10-17% fat energy • Classic food basket: 6 ingredients • Cereal • Pulse • Oil/fat • Fortified cereal blend • Sugar & salt • Sometime fish/meat • Grinding facilities if whole grain • Complementary food items • Fortified blended foods or staple foods to vulnerable grps • Essential vitamins & minerals: fresh foods, vegetables, fruits, fortified cereals, blended foods, condiments, tablets • UNHCR & WFP • Banned distribution dried milk powder (except in TFP) • bottle- feeding to be avoided • Culturally Acceptable & Familiar food
Feeding programme foods • Fortification • Adding micronutrients to foods • Iodized salt • Fortified blended food • Fortified blended foods • A flour composed of pre-cooked cereals + a protein source, mostly legumes • Fortified with vitamins + minerals • E.g.: corn soya blend (CSB) wheat soya blend (WSB) plumpynut
Implementation of GFR distributionMain Factors for success • Political willingness (donors) • Adequate planning & good logistical organization • Registration of refugees, ration cards (UNHCR) • Distribution system: equity, representative, head of family (natural unit targeted for distribution) registered • Good organization: regular distributions, well- planned site (1/20,000-30,000 refugees) • Regular monitoring of ration • Clear definition of the agreed responsibilities of partners w/ effective coordination
Problems • Gaps in food supply/delivery • Lack of funds, insufficient supplies, poor management • Food losses • During transport, warehousing, distribution, storage of large amounts food → security problems • Inadequate nutrient content of ration (long term programs) • Food diversion • By households in exchange for non food items/complementary food items: positive effects • By powerful grps → inequities in access: security problem, detrimental effects • Poor organization of distribution & logistical problems: ↓security • Lack of coordination among partners supplying all items regularly • Problems w/ food preparation • Lack cooking utensils/fuel • Lack of knowledge to prepare items distributed
Alternative to General Food Distribution • Opportunities for refugees to acquire food by themselves • Cash distributions • Distributions of food items w/ hi economic value & local demand • Income-generating programs & support for individual efforts to grow foodstuffs • Food-for-work programs • Mass preparation of cooked meals • Rare situations of great insecurity, temporary solution • Heavy logistical requirements, negative psychosocial consequences for population
Supplementary Feeding Programs • Not a substitute for inadequate general ration • Extra ration provided must be additional to, not a substitute for the general ration • Based on prevalence of malnutrition & aggravation factors • High MR • High prevalence of infection • General ration below minimum requirements
Identifying those Eligible • Active identification and F/U those at risk • House to house visits • Children U5, elderly, malnourished, ill • Mass screening of all children • Screening on arrival w/ registration • Referrals by community /health services
Supplementary (selective) Programs • Wet rations • 500-700Kcal • Prepared in feeding centre kitchen, consumed on site twice/day • Beneficiary has to come for meals to feeding center, every day • May substitute for a regular meal at home • Dry rations • 1,000-1,200Kcal • Hi protein source & hi energy source (oil) • Premixed cereal or blended food as base/Plumpynut • Take home for preparation & consumption • Rations distributed once weekly • Preferred • Easier to organize, less staff, lower risk transmission infection • Less time consuming for mother, family life preserved, food shared
Therapeutic Feeding Programs • On site wet feeding (therapeutic milk F75 & F100) • Intensive medical care • Infection & dehydration • Psychological stimulation during rehabilitation phase • 150Kcal/kg/day • 3-4g protein/kg/d • Frequent meals • Phase I: 8-10 meals/24h (usually lasts 1 week) • Phase II (rehabilitation): 4-6 meals/24h
