MID-UPPER ARM CIRCUMFERENCE TAPE (MUAC), adult, PP

Device for measuring the Mid-Upper Arm Circumference (MUAC) in adults (18 years and older), including pregnant or breastfeeding women and the elderly.

MUAC is particularly sensitive to acute weight loss, as it reflects the degradation of peripheral muscle and subcutaneous adipose tissue.

MUAC measurement can be used as a rapid method for assessing the nutritional status of adults and is increasingly used as a method for identifying adults who require nutritional intervention.

It is particularly useful among PBWG (Pregnant, Breastfeeding Women and Girls) for identifying those who need nutritional supplementation as a preventive measure for poor birth outcomes.

The brachial circumference is always measured on the left arm, halfway between the shoulder and the elbow. The arm should be in a relaxed position alongside the body.

• Place the strip in position, following the arrows to create a bracelet.
• Slide the tape over the wrist and move it halfway up the arm.
• Adjust the tape to fit snugly in the middle of the arm, ensuring it is neither too tight nor too loose.
• Read the number indicated at the arrow.

Model developed by MSF nutritionists in 2003 to assess the nutritional status of adults in emergency situation.
