초록

본 연구는 우리나라 출생아 전수(n=617,867)를 대상으로 산모 연령과 영아 사망과의 관련성을 파악하고자 시행하였다. 연구자료는 인구동태통계자료와 영아사망조사자료를 연계하여 사용하였고, 산모 연령에 따른 영아 사망 위험을 파악해 보기 위해 출생아의 성별과 다태 여부, 출생순위, 저체중아 여부, 선천성기형 여부를 보정한 다중 로지스틱 회귀분석을 시행하였다. 여러 혼란요인을 보정한 분석 결과, 25-29세 산모에 비해 20세 미만 산모(Odds ratio [OR], 5.29, 95% confidence interval [CI], 3.51-7.98)와 20-24세 산모(OR, 1.44, 95% CI, 1.23-1.69), 35-39세 산모(OR, 1.28, 95% CI, 1.11-1.46), 40세 이상 산모(OR, 1.94, 95% CI, 1.53-2.45)에서 영아 사망 오즈가 통계적으로 유의하게 높았다. 결론적으로, 이번 연구를 통해 35세 이상 고 연령 산모와 25세 미만의 저 연령 산모에서 영아 사망 위험이 높은 것을 확인할 수 있었고, 이들에서 영아 사망 위험이 높은 이유는 저체중아나 미숙아의 출산이 많기 때문으로 보인다. 산전관리 시 고령 산모의 경우 생물학적인 문제를 극복할 수 있는 관리정책이 만들어져야 할 것으로 보이고, 저 연령 산모의 경우 사회경제적인 부분과 사회적 편견 문제를 해결할 수 있는 관리정책이 만들어져야 할 것으로 보인다.

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.
