Key Criteria for Severe Acute Malnutrition (SAM) Identification

The identification of Severe Acute Malnutrition (SAM) in children aged 6 to 60 months relies on specific anthropometric and clinical indicators. Based on the provided assessment criteria, the following are key identifiers:

• Criterion II: Weight-for-height less than -2 S.D. This anthropometric measure indicates a child's weight is significantly below the expected norm for their height, suggesting acute malnutrition. The mathematical expression is: $\text{WHZ} < -2 \text{ S.D.}$
• Criterion IV: MUAC less than 120 mm Mid-Upper Arm Circumference (MUAC) is another critical measure. A MUAC below 120 mm is considered indicative of acute malnutrition in this context. The expression is: $\text{MUAC} < 120 \text{ mm}$
• Criterion VI: Dehydration Dehydration is a significant clinical sign often associated with severe illness in malnourished children. Its presence warrants classification as a severe condition requiring urgent management.

Therefore, the combination of these three criteria (Weight-for-height < -2 S.D., MUAC < 120 mm, and Dehydration) forms the basis for identifying SAM cases within this framework.
