1980년1월부터 1987년 7월까지 만 7년 7개월동안 전남대학병원 산부인과에서 분만하였던 총 8205명의 임산부중 35세이상의 임산부 280명을 조사군으로 하고 동기간에 분만하였던 경우에서 무작위로 추출한 20-30세의 임산부 285명을 대조군으로하여 다음과 같은 결론은 얻었다. 1. 35세이상 임산부의 발생빈도는 전체분만중 3.7%이었으며, 35세이상 초산부의 발생은 전체분만의 0.6%이었다. 2. 산모체중, 고혈압, 태반조기박리 및 제왕절개술은 노령임산부군에서 대조군보다 의의있게 높았고, 임신주수, 진통시간, 전치태반, 요로계감염, 산후출혈, 다태임신 및 조기파막은 두군간에 의의있는 차이가 없었다. 3. 낮은 Apgar점수와 자궁내 태아사망 및 거대아는 노령군에서 의의있게 높았고 태아성비와 태아기형은 두군간에 의의있는 차이가 없었다. 4. 노령임산부군에서의 안 좋은 infant outcome에 대해 산모체중, 고혈압, 또는 태반조기박리는 그 단독으로 통계학적으로 유의성있는 영향을 미치지 않았다. 결론적으로 노령임산부에서의 안 좋은 infant outcome은 산모체중, 고혈압, 또는 태반조기박리의 어떤 한 경우에 의해 영향받지 않았고 이는 아마도 여러 가지 복합적인 것에 의한 것으로 사료되며, 노령임신은 고위험임신으로 간주되어야 하고 철저한 임신 및 분만관리가 필요할 것으로 생각된다.

With the changing life patterns for women in current society, there is often a postponement of childbearing . Thus the impact of older maternal age on pregnancy outcome becomes increasingly important . It has been known that pregnancy outcome of women 35 years of age or older are considered to be less favorable. To examine this hypothesis, 280 pregnancy in women whose age was 35 or more years at delivery were compared with 285 pregnancy in women whose age 20 to 30 years at delivery at Department of Obsterics and Gyunecology, Chonnam University Hospital from January 1980 to July 1987. The fetus under 1000 gm was excluded. the results obtained were as follows; 1. Study group was 3.7% of total delivery 8205 cases .Primiparous women were 15% and multiparous women were 85% in the study group . 2. The older women had higher weights. There was also an increased frequency of hypertension, placental abruption and cesarean section in the older women, But gestational age, length of labor , the frequency of placenta previa urinary tract infection postpartum hemorrhage, multifetal pregnancy, preterm delivery, and PROM were not statistically difference between two group . 3. Low Apgar scores, intrauterine fetal death, and macrosomia were more frequency in the older women but there was a no statistically difference between two groups in the fetal sex ratio, fetal anomaly, and LBW infant. 4. There was no infuence in the infant outcomes when women with obesity, placental abruption , or hypertension was exclued from analysis. This investigation indicated that the pregnancy outcomes of women 35 years of age or older are considered to be less favorable than those of younger women. So careful antenatal and intrapartal care should be performed for the old aged pregnancy women.
