Peng et al developed equations for estimating the height and weight of Chinese adults using simple anthropometric measurements.
Subjects: 1,532 males and 1,753 females with ages from under 20 to over 80 years.
(1) knee height in cm
(2) hip circumference in cm
(3) mid arm circumference in cm
(4) age in years
body height in cm =
= (2.2871 * (knee height in cm)) – (0.0741 * (age in years)) + 52.0334
NOTE: In the article the constant given is "2.0334", However, when this is used for the mean values in Table 3 (page 329) a height of only 106 cm is returned vs the mean height of 155 cm. If the mean data for males is entered in the equation below, then a value very close to the mean height is returned.
body weight in kilograms =
= (1.0831 * (mid arm circumference in cm)) + (0.8203 * (hip circumference in cm)) – 51.3536
• R^2 for height is 0.7691
• R^2 for weight is 0.8679
= (2.4163 * (knee height in cm)) – (0.0694 * (age in years)) + 48.5233
= (1.1268 * (mid arm circumference in cm)) + (1.1228 * (hip circumference in cm)) – 72.4104
• R^2 for height is 0.8116
• R^2 for weight is 0.8530
