A study was carried out on the premature delivery related to prenatal care of pregnant women through examining clinical charts for 622 premature babies and 591 mothers who underwent confinement at Seoul National University Hospital during the period from 1963 to 1968.
During this period number of births at the Hospital totaled 5,297 with 5,234 mothers. Among the 591 women who delivered premature babies. 131 had received antepartum cares at tile Hospital and the rest
had not.
The following findings were derived from the study :
1. The age distribution of all women in childbed and of the women who had delivered premature babies were almost similar.
2. The secondary sex ratio of 5,297 newborn babies was 104.8:100. but that of 622 premature babies was 95.0:100.
3. Among the mothers of premature babies, 48.2 per cent of those who had never delivered full term babies were found to have had premature delivery two times arid most of the primipara women had this at the first and single experience.
4. Incidence of prematurity among those who were born at the Hospital seemed to increase as years went by.
The average incidence rate was 12.2% of the total hospital delivery under observation. It was lower(6.7%) with the "prenatal care" group than with the group who did not receive a care(15.1%).
5. The number of premature births were evenly distributed throughout the four seasons.
6. Out of mothers of premature babies who had received prenatal care at hospita1, only 19.8% reported having been free of complications during gestation and labor. But 30.2% of the group having received no care reported no obstetrical disorders were toxemia(22.1%) and twins (16. 1%) among prenatally cared group, while toxemia(22.4%) and chronic infections(9.8%)were major complications among the "no care" group.
7. The survival rates of premature babies by the time of discharge from the hospital were 79.2% with the prenatally cared group and 63.0% with the "no case" group.
8. Still-birth was reported with 12.7% of the total women reported with 12.7% of the total investigated but 6.7% with the prenatally cared groups and 14.4% among the group with no care. Among the probable causes of still births, 29.1% could be attributed to maternal causes and the other 44.3% to faal.
Among the prenatally cared group, however, on case was referable to maternal cause.
9. By birth weight of premature babies the still birth rated 37.7% of the group under 1,000gm and 5.2% of the group over 2,000gm.
Such rates dramtically declined as the gestation periods grew longer.
10. The deaths following premature births(until discharge from hospital) rated high in low birth weight and short gestation period groups. The death rate was also lower in prenatally cared group than in the group not receiving any care.
