  • Mid-arm circumference and mid-arm circumference/head circumference ratio(MAC/HC) were measured in 207 AGA(appropriate for gestational age) infants delivered at 26 to 42 weeks of gestation from January 1990 to December 1993 in Yeungnam University Hospital, Taegu, Korea. There were linear relationships between MACs and MAC/HC ratios and gestational age(MAC : y=0.3181x - 2.2069, r=0.81, p<0.001 ; MAC/HC ratio : y=0.0049x+0.1128, r=0.62, ; < 0.001). Using standard curves of MAC and MAC/HC ratio according to the gestational age, measurement of MAC or MAC/HC ratio can be a noninvasive, simple method to evaluate the intrauterine growth of newborn infants and the nutritional status of growing premature infants.
