다국어 초록 (Multilingual Abstract)

Purpose : The aim of this study was to access the pregnancy tendency and delivery in women aged 35 years and older.
Subject and Methods : Among the women who delivered in Pusan national university hospital during 2005, 70 women aged more than 35 years were selected as a study group, and 70 women aged less than 35 years as a control group. The statistical analysis was performed using Chi-square tests, and statistical significance was defined as p value<0.05.
Results : The preterm delivery was significantly higher in women aged 35 years and older (study group) (30.0%) than control group (15.7%) and cesarean birth rate was also higher in study group (71.4%) than control group (48.6%). In antenatal complications, there was no statistical differences in both groups, but the incidences of pregnancy induced hypertension, placenta previa, and uterine myoma was higher in study group compared with control group. In comparison of neonatal outcomes, the incidence of 5-minute Apgar score less than 7 was significantly higher in study group.
Conclusions : Pregnancy in old age is currently a rising trend. While they might have the tendency to show prenatal complications, neonatal complication and difficult decision making in delivery method, early detection and treatment of presumable complications by adequate antenatal care and appropriate selection of delivery method can reduce the cesarean section rates and obtain relatively successful pregnancy outcome.
