This is one part of "Community Pregnancy Study" which has been carried out at three Myons of Chunseong Gun area, Kangwon Province over the period covering from May 1973 to April 1976 with financial assistance from UNFPA. In order to increase the sample size the author has included retrospective information for the period from May 1971 through April 1973.
Among the three Myons where the study was actually done, one Myon, called Shindong Myon, has been a demonstration area of the Community Health Program by the School of public Health, Seoul National University since 1972. The intensive health care program is being carried out there for the purpose of field training for students, demonstration model for comprehensive health services, and health research activities.
In the present analysis, the pregnancy interval is defined as the period between the end of a certain pregnancy and the beginning of next one, and is assumed to be made of two components:
Ⅰ) Infecundable period including post·partum amenorrhoea and anovulatory period,
Ⅱ) Fecundable period including ovulatory period.
Since the pregnancy interval is the elementary basis for the enhancement of MCH, the author attempted to analyze from these data how the types of previous pregnancy terminations affected the following closed pregnancy intervals.
This study attempted to compare by Myons Ⅰ) how the family planning programs prolong pregnancy intervals, Ⅱ) the differences among different types of previous pregnancy terminations, and Ⅲ) the impact of pregnancy interval to MCH.
The results are summarized as follows.
Ⅰ. The number born between 1935-1954 amounted to 655(91.9%) in total, which is reasonable when compared with the distribution of the married women of child-bearing age in general (Table 1).
Ⅱ. By the number of women 543(76.4%) experienced one interval, 149(20.7%) two, and others over three (Table 2).
Ⅲ. There were 912 cases in total and among them 735(80. 6%) did not practice contraception during the interval (Table 3).
Ⅳ.The increase in the number of living children resulted in the lengthening of the pregnancy interval regardless of contraception (Table 4).
Ⅴ. The mean of all the intervals was 20.8 months with the use of contraception and 13.4 without it (Table 5).
Ⅵ. The pregnancy interval after live birth was 23.3 months with the use of contraception, and 6.3 without it (Table 5).
Ⅶ. The interval after fetal death was 13.7 months with contraception and 6. 3 without it. Also the interval after spontaneous abortion was 11. 6 with contraception and 6. 1 without it after induced abortion 14. 5 with contraception and 6. 4 without it (Table 5).
Ⅷ. It was observed that as the mothers´ age at the beginning & end of interval increased, so did the length of interval regardless of contraception (Table 6).
Ⅸ. The regression & correlation analyses were performed on the pregnancy interval by the mothers´ age as shown in the end of Chapter Ⅲ.
The findings from the results are as follows;
Ⅰ. When the contraception is used, the pregnancy interval after live birth is very similar to the one medically recommended.
Ⅱ. The longer pregnancy intervals are observed for the higher brackets of mothers´ age.
Ⅲ. The experience of contraception prolonged the pregnancy interval by 7. 4 months.
Ⅳ. It may be desirable to concentrate on the practice of contraception, which is found to be very effective method of family planning, rather than the induced abortions.
