Sexual differences in anthropometric measurements have been studied in
a sample of 17,787 preterm and full-term infants, born between 1980 a
nd 1990 in the maternity of Clamart Hospital (Hauts-de-Seine, France).
Body weight, body length, head and chest circumferences were found si
gnificantly larger in male newborns. Conversely, the subscapular and t
ricipital skinfold thicknesses had higher values in females. Such grea
ter fatness in females could be related to the better outcome in neona
tes of this sex. The weight-for-height indices, however, did not show
this female advantage: the body mass index (BMI) and the body weight/b
ody length index were greater in male neonates, the ponderal index (PI
) showed no sexual difference.
