Despite growing policy and research interests in reproduction health for healthy child birth, the rates of adverse birth outcomes such as low birthweight and preterm has grown in Korea. The main stream of study on determinants of birth outcomes has focused on maternal age effects, relatively overlooking other socioeconomic factors. The purposes of this study are to examine the current trends of birth outcomes, and to explore determinants of birth outcomes. paying special focus on paternal age and socioeconomic factors. For the purposes, this study employs the birth data from the Statistics Korea. The results present that the growth in adverse birth outcomes is mainly attributable to the rate of adverse birth outcomes in each age group and very partly to advanced maternal age. This demonstrates the worsening of reproductive health at population level. Also, this study shows not only maternal age effects but also paternal age effects. The adverse paternal effects are found at both very young (under 25 yrs) and very old (over 40 yrs) ages, but paternal age effects are significantly decreased after ontroling the effects of socioeconomic factors. The results also show that low social economic status of parents and pregnancy prior to marriage have negative influences on birth outcomes. These findings emphasize the necessity of preconceptional care to improve reproductive health at population level based on life-span approach.
