Cattermole et al developed a simple equation for estimating body weight of Chinese children based on mid-upper arm circumference. The authors are from the Chinese University of Hong Kong and the University of Melbourne.

NOTE: Cattermole also developed an equation for estimating weight of adolescents and adults using MAC.


Patient selection: Chinese children from 6 to 11 years of age



(1) mid-upper arm circumference in centimeters


estimated body weight in kilograms =

= (3 * (MAC)) - 30
