Physical parameters in Japanese newborns.

A total of 19 physical parameters of the head, face, chest, and the fingers were examined in Japanese 50 male and 50 female newborns, measured 8 to 64 hr after birth. Exceptional values were excluded referring to the estimated mean and standard deviations. Normal values are presented as mean +/- 2 S.D. for each sex. As compared with Caucasian newborns, the Japanese newborns showed longer inner canthal and shorter outer canthal distances, shorter ear lengths, and longer palm and middle finger lengths.
