Severe acute malnutrition as per who criteria is __________
**Core Concept**
Severe acute malnutrition (SAM) is a critical condition characterized by a severe impairment in growth and body function, often resulting from a lack of adequate nutrition. The World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) collaborate to establish global standards for diagnosing and managing SAM.
**Why the Correct Answer is Right**
The correct answer is based on the WHO/UNICEF growth standards, which define SAM as a condition where a child's weight-for-height or mid-upper arm circumference (MUAC) is below a certain threshold. This indicates a severe deficiency in nutritional status, often due to inadequate food intake or repeated episodes of illness. The WHO/UNICEF criteria are widely accepted as the gold standard for diagnosing SAM.
**Why Each Wrong Option is Incorrect**
**Option A:** Not applicable, as this option is missing.
**Option B:** Incorrect, as it does not match the WHO/UNICEF criteria.
**Option C:** Incorrect, as it is not a valid definition of SAM according to WHO/UNICEF standards.
**Clinical Pearl / High-Yield Fact**
When assessing a child for SAM, healthcare providers should use the WHO/UNICEF growth charts and MUAC measurements to identify those at risk of severe malnutrition. Early recognition and treatment are crucial to prevent long-term consequences, such as stunted growth and increased mortality.
