What is Acute Malnutrition?
Acute malnutrition, also known as wasting, is a rapid decline in nutritional status that results in a low weightforheight ratio. It is measured by two main indicators:
- WeightforHeight Zscore (WHZ)<2 or midupper arm circumference (MUAC)<125mm
- Presence of nutritional oedema (kwashiorkor)
The condition is lifethreatening, especially in children under five, and often coexists with infection, inadequate food access, poor watersanitationhygiene (WASH) conditions, and social instability.
IPC Framework Overview
The Integrated Food Security and Nutrition Programme (IPC) provides a classification system that helps humanitarian actors prioritize actions based on the severity of foodsecurity and nutrition emergencies. The IPC scale ranges from Phase 1 (minimal) to Phase 5 (famine). For acute malnutrition, the focus lies on Phases 3 (Crisis), 4 (Emergency), and 5 (Famine).
| Phase | Definition | Typical Nutrition Indicators |
|---|---|---|
| 1 Minimal | Normal food security, low acute malnutrition | GAM <5% |
| 2 Stressed | Reduced food consumption, risk of deterioration | GAM 59% |
| 3 Crisis | Significant food gaps, acute malnutrition rising | GAM 1014% |
| 4 Emergency | Largescale loss of livelihoods, acute malnutrition severe | GAM 15% |
| 5 Famine | Widespread food shortage, mortality spikes | GAM >30% and mortality >2/10000/day |
Applying the IPC framework to acute malnutrition enables a coordinated response that matches the intensity of the crisis with the appropriate scale of intervention.
Key Assessment Tools
Rapid, reliable data are essential for placing a community on the IPC scale. The most common tools include:
- SMART (Standardized Monitoring and Assessment of Relief and Transitions) integrates household foodsecurity surveys with nutrition measurements.
- IPC Acute Malnutrition Assessment (AMA) a concise, sectorwide protocol that captures WHZ, MUAC, oedema, and mortality.
- MUAConly screening useful in emergencies where weighing scales are unavailable; a MUAC<115mm indicates severe acute malnutrition (SAM).
- Rapid Nutrition Assessment (RNA) combines community focus groups, market assessments, and healthfacility data to triangulate risk factors.
Tip: Conduct assessments at least every 30days during an emergency, and after any major shock (e.g., flood, displacement).
Intervention Strategies by IPC Phase
Phase3 Crisis
- Scale up outpatient therapeutic feeding programmes (OTP) for SAM and moderate acute malnutrition (MAM).
- Introduce targeted Supplementary Feeding Programs (SFP) for atrisk children (MUAC 115124mm).
- Strengthen WASH interventions to reduce diarrheal disease.
- Begin cashfornutrients vouchers where markets are functional.
Phase4 Emergency
- Deploy readytouse therapeutic foods (RUTF) and readytouse supplementary foods (RUSF) in large quantities.
- Establish inpatient care (Stabilisation Centres) for children with complications.
- Implement mass nutrition screening using mobile teams.
- Coordinate with foodsecurity clusters to deliver multisectoral assistance (food, cash, livelihoods).
- Integrate psychosocial support for displaced families.
Phase5 Famine
- Activate emergency nutrition relief with international assistance (e.g., UNICEF, WFP).
- Scale up therapeutic feeding to meet >200% of the estimated need.
- Provide general food distributions alongside nutritionspecific interventions.
- Implement mortality surveillance to track trends daily.
- Plan for postfamine recovery agriculture inputs, water infrastructure, capacity building.
Monitoring & Evaluation (M&E)
Effective M&E ensures that interventions remain appropriate throughout the emergency cycle.
- Coverage Monitoring track the proportion of SAM and MAM children reached versus estimated need.
- Outcome Indicators cure rate 75%, default rate 15%, mortality 10% among treated cases.
- Process Quality Audits regular supervision of OTPs and Stabilisation Centres using standard checklists.
- Data Feedback Loops weekly data aggregation at the cluster level, monthly review at the national coordination forum.
- Learning Reviews afteraction reports after each phase transition to capture lessons and adapt protocols.
Digital tools such as DHIS2 or KoBoToolbox can streamline data collection and realtime visualization, especially in hardtoreach settings.
