한국부인의 임신소모율수준 추정에 관한 분석

Abstract

The present study is aimed at the estimation of the level of pregancy wastage from the data collected retrospectively in 1976 for the prohability sample of 4,854 Korean women between age 15 to 44 living with their husbands in both urhan and rural areas throughout the country For the purpose of the present study on pregnancy wastage is classified into three groups: (1) pregnancies terminated by induced abortions, (2) pregnancies terminated by spontaneous abortions, and (3) pregnancies terminated by stillbirths. The distinction of each event is recorded on the given questionnaire on the basis of verbal report of the respondents. An average number of prenancy is found to be 4.33 per woman. Of these, decreasing tendency in the number of pregnancy by marriage cohort was clearly shown from 7.20 per woman before 19,,0 to 1.86 in the period of 1971 ~ 1975. The level of pregnancy wastage is 250 per 1, 000 pregnancies. The present data have consistently shown that induced abortion is a critical factor affecting the level of pregnancy wastage. The total pregnancy wastage rate, 250 per L 000 pregnancies were consisted of the rate of 190 caused by induced abortion, the rate of 53 by spontaneous abortion, and the rate of 7.4 by stillbirth. The preganancy wastage rate increases consistently with the order of pregnancy and its effect is mainly the result of association with induced abortion. In short, the most important features emerge from this analysis: (1) the level of pregnancy wastage rate in Korean women is significantly associated with induced abortion, (2) an increasing tendency of pregnancy wastage in Korean women can not be interpreted as a result of maternal health problem.
