Acute Malnutrition – A rapid decline in weight and height that occurs within weeks to months, often identified by a weight‑for‑height Z‑score below ‑2.
Explanation #
Acute malnutrition reflects a deficit in energy and protein intake, compounded by infections that increase metabolic demands. It is diagnosed using anthropometric measurements and can lead to impaired immune function and delayed neurodevelopment.
Example #
A 12‑month‑old boy presents with a weight‑for‑height Z‑score of ‑2.5, indicating moderate acute malnutrition; his diet lacks adequate animal‑source protein.
Practical application #
Rapid therapeutic feeding protocols using ready‑to‑use therapeutic foods (RUTF) are implemented in community health centers to restore weight gain.
Challenges #
Ensuring timely identification, maintaining supply chains for therapeutic foods, and addressing underlying causes such as food insecurity and poor sanitation.
