Taufiq et al developed an equation for estimating the birth weight of a neonate from the mid-upper-arm circumference (MUAC). The authors are from the University of Hassanudin and Dr. Wahidin Sudirohusodo Hospital in Indonesia.

Patient selection: Indonesian newborn


Output: birth weight in grams



(1) mid-upper-arm circumference in cm


body weight in grams at birth =

= (416.95 * (MUAC in cm)) - 1776.383



• An arm circumference < 10.5 cm was 100% sensitive and 99.4% specific for low birth weight.
