This study inverstigated low birth weight in birth certificated data(711.129 births) during 1994. obtained from National Statistical Office of Korea.
The distribution of birth weight was 2.75 percent in low birth weight(<2.5㎏ : LBW). 90.60 percent in normal birth weight and 6.65 percent in large birth weight(4.0㎏ : LABW).
Low birth weight rate in female was higher than that of male(odds ration : 1.25). The percent of low birth weight increased with increasing birth order : percents of LBW were 2.67 percent for 1st birth order. 2.75 percent for 2nd birth(odds ratio : 1.02) and 3.52 percent for 3rd and over(odds ration : 1.33).
The percent of LBW and LABW increased with maternal age. The odds ratios for low birth weight in maternal age(reference group : 20-29 years) were 1.35 for women aged under 19 and 1.39 for women aged 30 and over. The risk for low birth weight in women age 35 and older was higher than women under 34 years(odds ration : 1.76)
