Definitions wikipedia

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

REFUGEE SITUATION

  • Food & nutritional security threatened

  • Malnutrition, disease & death

  • Refugees need partial/full food support (acute phase), +/- nutritional rehabilitation


Complex causes of malnutrition

Complex Causes of Malnutrition


Objectives

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

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

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


Assessme n t basic information

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

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

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

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

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

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

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

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


Selective feeding programmes

Selective feeding programmes


Class ical emergency food interventions

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

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 crisis simplified decision tool

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).

Implementation of gfr distribution main factors for success

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

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

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

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

Identifying those Eligible
