Results: Birth weight in male neonates was on average, heavier 137 g than females; There was no significant difference in birth weight among the different ethnic. The mean birth weight for 1996 to 2000 increased by 125 g compared with 1990 to 1995. The number of the macrosomia newborn became higher and low birth weight newborn was lower after 1996.
