Birth weight estimation of newborns utilizing chest and arm circumference

A study of 547 births in Thaketa township showed a strong correlation between birth weight with chest circumference (r = 0.71) and mid arm circumference (r = 0.70). Multiple regression analysis of birth weight on chest and mid arm circumference was: Birth weight = - 1870.41 + (mid arm circumference x 192.03) + (chest circumference x 91.97). The value of F statistic (371.97) was significant (p < 0.001) indicating the usefulness of chest and mid arm circumference in predicting birth weight.
