Abstract

OBJECTIVE
To access the pregnancy tendency and delivery in women aged 35 years and older.
METHODS
From December 1999 to May 2001, 954 deliveries were in Ilsan Paik Hospital. Among them we compared 89 cases of pregnant women aged 35 years and older with under 30 year of age as control group 99 cases. The statistical analysis was performed using Chi-square tests, Mantel-Haenszel trend test, and statistical significance was defined as p value<0.05.
RESULTS
The preterm delivery was higher in women aged 35 years and older (study group) (31.5%) than control group (8.1%) and cesarean birth (C/SEC) rate also higher in study group (61.8%) than control group (36.3%). In antenatal complications, there are no differences in both groups, but in postpartum complications, 4 cases hysterectomy were in study group compared with control group 1 case. In comparison of neonatal outcomes, neonatal intensive care unit (NICU) admission and congenital anomalies are higher in study group. Especially, in comparison of nulliparous women, study group (n=21) have higher C/SEC rate and preterm delivery than control group (n=63), but in pregnancy outcome there was no differences in both groups.
CONCLUSION
There are no significant differences in pregnancy outcomes in both group, although preterm delivery and C/SEC rate are higher in elderly gravida. So elderly gravida is no more than high risk group, if appropriate management will be done.
