Mid Upper Arm Circumference (MUAC) is a simple, rapid, and reliable anthropometric measurement used to assess the nutritional status of children, particularly those between 6 and 59 months of age. It is widely used in community health programs, growth monitoring, and emergency settings because it requires minimal equipment, can be performed by trained health workers or caregivers, and provides immediate information about the risk of acute malnutrition. MUAC measures the circumference of the upper arm, which reflects the muscle and fat stores of the body. Since muscle wasting is one of the earliest signs of acute malnutrition, MUAC is an effective screening tool for identifying children who require nutritional intervention. The equipment needed for MUAC measurement includes a color-coded, non-stretchable MUAC tape. The tape is lightweight, portable, inexpensive, and specifically designed for use in children. The tape contains numerical measurements in millimeters and color bands that simplify interpretation. The correct procedure for measuring MUAC is essential to ensure accuracy. First, the child's left arm is bent at a right angle. The health worker identifies the midpoint between the tip of the shoulder (acromion process) and the tip of the elbow (olecranon process). This midpoint is marked. The
