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 Complex Causes of Malnutrition 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 Support World 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 Access to fuel, utensils, Current nutritional status containers Local food availability Present/over time Milling possibilities Food preferences Family capacity to prepare, store, process food 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 Availability of human resources Storage capacity & quality Delivery schedule of food & non food commodities Other agencies activities & assistance provided: Quantity, items, frequency Logistics constraints Security constraints 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 U5 W/H % of median value W/H in Z scores MUAC Moderate Severe 70-79% < 70% -3 to -2 Z < -3 Z (edema) 115 - <125 mm < 115 mm (edema) Adults BMI (wt in kg)/(ht in m)2 16-17 MUAC (pregnant women) < 16 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.

Malnutrition rate (GAM) 10 – 14 % or 5 – 9 % plus aggravating factors - Supplementary feeding targeted to individuals identified as malnourished in vulnerable groups - Therapeutic feeding for SAM individuals Malnutrition rate (GAM) ≥ 15 % or 10 – 14 % with aggravating factors[1] - General rations; plus - Supplementary feeding for all members of vulnerable groups. - Therapeutic feeding for SAM individuals [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.
