Abstract

The diagnosis of altered fetal growth requires multiple criteria that include not only weight and length measurements, but also head, abdominal, and thigh circumference measurements. This cross-sectional study presents the normal standards for thigh circumference, thigh-to-head ratio, and Rohrer's ponderal index in newborn infants from 27 to 41 weeks' gestation, in relation to gestational age and birth weight. A thigh-to-head ratio of < 0.38 and a ponderal index < 2.3 in a term infant are important measurements for appropriate diagnosis of impaired fetal growth. These standards may also serve as reference for comparison with fetal ultrasonographic measurements.
