Supine length, weight and head circumferences of 10241 neonates (5241 boys, 5000 girls, sex ratio 105) born in Arak (central Iran) in 2002are reported. Mean+SD of boys and girls (p-value for sex difference) supine length (mm), weight (gr) and head circumference (mm) were estimated as 501+30 and 497+31 (p<0.001); 3194+586 and 3100+532 (p<0.001); 351+18 and 345+l8 (p<0.001), respectively. Supine length and weight of our subjects were significantly lower than that of their American counterparts (p<0.01), but our boys head circumferences were significantly higher than the NCHS reference data (p<0.01), while no significant differences were seen among girls....
