Abstract

PURPOSE
Premature and low birth weighted (LBW) infants as well as small for gestational age (SGA) infants have a high death rate and increasing the prevalence rate. We compared the proportion of these high-risk neonates and the relevant factor between the four regional settings.
METHODS
We reviewed the data from 2005 to 2010, from the Korea National Statistics Office and compared the proportions of premature infants, LBW infants and SGA babies and the relevant factors between Seoul, metropolitan cities and small-to-medium-sized ones.
RESULTS
Premature birth rate is as follows in each area: 4.00% in Seoul, 4.21% in metropolitan areas, 4.11% in small and medium size cities, and 4.27% in small towns. SGA birth rate is slightly lower in the medium-sized cities and higher in small towns. The birth rate of low birth weight infants is higher only in small towns (3.58%). It appears that low maternal age and low maternal education levels increase these high-risk newborns. Once calibrated variables, the result showed that the risk of premature infants is higher in the metropolitan areas (OR, 1.05), and the risk of SGA (OR, 1.06) and low birth weight (1.03) is higher in a small town.
CONCLUSIONS
There were significant differences in the premature infants, low birth weight infants and SGA babies between the four different regional settings. Following the adjustment of the relevant variables, the proportion premature infant was higher in metropolitan cities and SGA babies and LBW infants were higher in small ones.
