Intra-uterine growth curves for midarm and thigh circumferences.

Use of birth weight as a measure of intrauterine growth is hampered by several logistic problems. Both mid-arm (MAC) and thigh circumferences (TC) have been proved to be efficient alternative measurements. In this study MAC and TC were recorded on 2925 consecutive live births to derive intrauterine growth curves and provide normative data for an indigenous population.
