MID-UPPER ARM CIRCUMFERENCE TAPE (MUAC) adult

Definition

Device for measuring the middle-upper arm circumference in adults (18 years and older), pregnant or breastfeeding women and the elderly.

The MUAC is particularly sensitive to acute weight loss, since it reflects peripheral muscle and subcutaneous adipose tissue degradation. A circumference < 160 mm indicates a risk of mortality. The MUAC provides a rapid assessment of the nutritional status of adults and is increasingly used as a method to identify adults requiring immediate treatment.
