Differences in Wasting Assessment Through Middle‐Upper Arm Circumference (MUAC) Adjusted by Sex, Age and Geographic Origin for Children Aged 6–59 Months: New Reference Based on Anthropometric Surveys from 22 Low‐and‐middle‐income Countries

The Middle Upper Arm Circumference (MUAC) bracelet is a widely used instrument in public health assessments and humanitarian assistance projects. The WHO guidelines present a universal cut‐off point of 115 mm to determine whether a child has severe acute malnutrition. The objective of this study is to analyze the existing differences in the MUAC for boys and girls aged between 6 and 59 months, from 22 countries distributed in three different continents, in contrast to the use of this single cut‐off point. In addition, the creation of MUAC growth charts is presented for reference use.
