Abstract Intrauterine growth curves are the standard for assessing the growth of term and preterm infants and are widely used in the NICU setting. Standard anthropometric curves differ from reference curves in that these illustrate “ideal” fetal growth versus actual growth of infants over time, respectively. Newer intrauterine growth curves have been published to improve on earlier curves, by using more current, larger, and more diverse samples of infants for growth measurements (and because the earlier curves are based on samples of infants from outside the population it applies on). The goals for this study were to determine regional percentile values and compare them with currently used international curves, we determined the birth weight, length, head circumference and skin fold thickness of 1000 term neonates born in Ain Shams University Maternity hospital in Cairo, Egypt. Our results revealed that the mean birth weight, length, head circumference and skin fold thickness were 3241 g, 50.3 cm, 34.9 cm and4.19 cm respectively for boys and for girls were 3047 g, 49.1 cm, 34.2 cm and 3.9 cm respectively. So, the term males are heavier, taller and with larger head circumference and skin fold thickness than term females and Summary 102 differ from the currently used percentile curves of Lubchenco that underestimate the birth weight, height and head circumference at the 10th, 50th and 90th percentiles. So, The Lubchenco curves do not represent the current Egyptian population and this leads to misclassification of small for gestational age and large for gestational age neonates and it’s recommended to use the new national charts in Egypt in the assessment of full term neonates. |
