Abstract
The purpose of this study was to examine the relationship between maternal age and infant mortality in Korea(n=617,867). Data of Korean vital statistics linked National Infant Mortality Survey conducted on births in 1999 were used in this study. The odds ratios (ORs) of infant death by maternal age were estimated with the multiple logistic regression model, adjusting for gender, plurality, birth order, low birth weight, and congenital malformation. After adjusting for the relevant variables, the odds of infant death in the group of maternal age with less than 20 years(Odds ratio [OR], 5.29, 95% confidence interval [CI], 3.51-7.98), 20-24 years(OR, 1.44, 95% CI, 1.23-1.69), 35-39 years(OR, 1.28, 95% CI, 1.11-1.46), and more than 40 years(OR, 1.94, 95% CI, 1.53-2.45) was higher than that of reference group(25-29 years). In conclusion, the higher infant mortality in the group of maternal age with less than 25 years and more than 35 years in Korea appears to be due to higher proportion of low birth weight and pre-term birth. Prenatal care intervention programs which tackle biological factors for advanced maternal age and address socio-economic problems and social stigma for early maternal age should be devised.
