An attempt had been made to obtain current information on induced abortion among currently married women aged 15 to 44. The source of data was 1985 National Fertility and Family Planning Survey conducted by Korea Institute for Population and Health in may 1985. 1. At the time of the survey, 53 percent of currently married women aged 15 to 44 had experienced induced abortion: 25.5 percent of the respondents who had experienced induced abortion only one time and another 27.6 percent more than two times. 2. The proportion of women who had experienced induced abortion seemed to increase according to the advance in age. It seemed that there was no significant difference in the experience rate of induced abortion by academic career, and there was inverse relationship between the experience rate of induced abortion and the age at first marriage. The experience rate if induced abortion by the number of living children was highest among those who had three children as 65.6 percent. 3. To analyze the effect of induced abortion on fertility, this study employed multiple regression analysis as a statistical technique. Instead of index representing fertility level the number of living children served as dependent variable. Independent variables used in analysis included age, age at first marriage, education level, ideal number of children, religion, frequency of induced abortion, total number of pregnancies and participation in labor force. Standardized partial regression coefficient of induced abortion was no less than -0.61. So, it can be concluded that induced abortion offered the great contribution on the birth control. A consistant health education and efficient management of family planning program would be essential for effectiveness of contraceptive practice.

The purpose of this study was to investigate pregnancy, abortion and delivery rates among Korean teenagers. The subjects of this study were 11,433 teenagers aged 13-19 years in Seoul, Pusan, Taegu, Kwangju, Incheon, Taejeon and Ansan, Korea. Data were collected from Feb. 1994 to May 1995, 16 months, by schoolnurses or the researchers. The results showed pregnancy rate was 7.2 per 1,000 teenagers, the abortion rate was 4.3 per 1,000 teenagers, and the delivery rate was 1.2 per 1,000 teenagers. In the pregnancy experience, the main factors related to teenage pregnancy were love or marriage engagement. In the abortion experience, 53.9% of teenagers had had more than two abortion experiences, 38.1% midtrimester abortion, 22% complications after abortion, 36.0% sexual activity after abortion and 86.7% the financial support from partners or friends for abortion. In the delivery experience, 64.3% of teenagers delivered with no prenatal care and 42.9% had a delay in realizing they were pregnant. Fifty percent were delivered by non-professionals in non-medical institutions.

Despite the fact that the national family planning program in korea has accomplished its primary goals of fertility reduction and universal contraceptive use, the induced abortion is still high and there has been an increasing trend in the population sex ratio at birth. It seems that the changes in the imbalance of sex ratio have originated from traditonal boy preference. This indicates that much of the current family planning program can be overhauled, so that the program quality could be better controlled, by preventing the number of unwanted pregnancies and the imbalance of sex ratios. This paper aims, therefore, to examine the determinants of induced abortion through the investigation of pregnancy outcomes and their changes over time and to study the interaction between induced abortion, boy preference and the imbalance of sex ratio in Korea. The abortion rate had increased rapidly until the mid-1980s when there were about the same number of abortions as live births. Thereafter, the abortion rate has been maintained at this high level. By parity it shows a much higher abortion rate for a higher parity at all time. From the first parity, the sex composition of previous children stands out as the most important factor in deciding the pregnancy outcome at all time. The probability of a pregnancy ending in an abortion increases substantially when parents already had a son. The decline of the desired family size and the sustained strong son preference has made the sex of children a more important factor in the determination of the pregnancy outcome. Women's education has had consistently positive effects on the probability of a pregnancy ending in an abortion, but the effect shows a steady decline over time. The premarital pregnancy and urban residence also increase the abortion probability. This study suggests that the main concerns of the family planning program should be to strengthen the social support policies so as to weaken the son preference value leading to a balanced sex ratio and prevention of induced abortions.

Objectives This study aims to analyze Heart Rate Variability (HRV) in women after missed abortion compared with healthy women Methods We studied 35 women who visited Kang-Nam Kyung-Hee Korean Hospital after missed abortion from 01 January 2012 to 28 February 2015 (missed abortion group) and 35 normal women visiting medical examination center from 1 January 2014 to 31 December 2014 (Normal Group). We measured HRV of each women and investigated the difference of HRV between two groups. Results The standard deviation of NN intervals (SDNN) in Missed abortion group is lower than normal group. The square root of the mean square difference of successive NNs (RMSSD) in Missed abortion group is lower than normal group. However there was no significant difference. Total Power (TP) and Low frequency power (LF) is significantly lower in Missed abortion group compared with normal group. High frequency power (HF), Very low frequency power (VLF) and LF/HF ratio in missed abortion group is lower than normal group. but There was no significant difference. Conclusions Missed abortion group is lower in function of overall autonomic nervous system, especially sympathetic nerve.

In Korea, female workforce has reached more than 40% of total working population, but the effects of work on spontaneous abortion are yet to be examined. This study as conducted to investigate the occupational effects on spontaneous abortion. Medical insurance claim data were used to examine the effects of the employment status and industry of employment on spontaneous abortion. The study population was composed of females, aged $15{\sim}44$, who were the beneficiary of medical insurance in the month of June, 1993. The working females covered by medical insurance for industrial workers, had the highest age-adjusted Spontaneous Abortion rate (SAB rate=claim frequency of spontaneous abortion/claim frequency of complication of pregnancy, childbirth and the puerperium), 6.65% whereas female dependants of medical insurance for industrial workers had the lowest age-adjusted SAB rate, 4.54%. Among industrial workers, the workers in manufacturing industry had the highest age-adjusted Spontaneous Abortion ratio(SAB ratio=claim frequency of spontaneous abortion/claim frequency of completly normal delivery), 43.2/100 whereas those in financing and service industry had age-adjusted SAB ratio, 16.2/100 and 20.5/100, respectively. The results of the study suggest the adverse effect of manufacturing Industry on reproduction. Work environments such as chemical exposures, overwork, awkard posture, and job stress should be further studied for their effects on reproductive functions of female.

Purpose: The objective of this study is to investigate the knowledge and attitude on the contraception and induced abortion in female high school students for providing the fundamental data in developing a practical sexuality education program for the healthy conception and childbirth in female high school students who are in the child-bearing age. Also, this study provides some foundational data for developing prevention education, counsel, and nursing intervention programs. Methods: Data were collected from 270 high school girls by self-report questionnaires from August 1, to September 31, 2010. Data was analyzed by percentage and Pearson correlation coefficient using SPSS/WIN 17.0. Results: The correct rate of contraception and induced abortion were 43.3% and 48.8% respectively. Participants had a moderate attitude toward contraception and a permissive attitude toward induced abortion. Participants who had high score and home sex education were higher correct rate than any other. Conclusion: This study indicates that efforts should be made to provide education on contraception and induced abortion to high school girls to increase awareness. Also, educational programs should be designed to improve knowledge as well as promote a more positive attitude toward contraception and induced abortion.

This study was carried out to investigate the prevalence of Neopsora (N) caninum infection in Korean dairy herds. To determine the prevalence of antibodies to N caninum in Korean dairy cattle, a total of 1,688 sera including 895 sera taken from 30 herds having recent high abortion rate and 793 sera selected randomly from 168 herds with no history of recent abortion problem, respectively, collected nationwide during a designated period were analyzed by indirect fluorescent antibody (IFA) test. Mean nationwide seropositive rate of the sera tested in herds and individual cattle tested were 53.5% and 35.6%, respectively. However mean seropositive rate of the samples from herds having abortion problem was approximately two and half times higher than those in herds with no recent abortion history. Regional seropositive rates of the samples from the herds with abortion problem were 48.6%, 51.6%, 44.4% and 71.4% at Kyunggi, Kangwon, Kyungbuk and Jeonnam province, respetively. Regional seropositive rates of the samples from the herds with no recent abortion problem were 35.6%, 18.3%, 16.5%, 37.5%, 19.4%, 33.3%, 32.1%, 3.8% and 0.0% at Kyunggi, Kangwon, Chungbuk, Chungnam, Kyungbuk, Kyungnam, Jeonbuk, Jeonnam and Jeju province, respectively. The results of this study suggested that N caninum infection was widespread and considerably associated with bovine abortion in Korea.

This research explores the current situation and determinants of induced abortion in Korea. Using 2000 National fertility Survey by Korea Institute of Health and Social Affairs, this study finds that induced abortion rate is rapidly declining so that the role of induced abortion in determining the level of fertility has disappeared. The fundamental reason for resorting to an induced abortion for Korean women is to avoid unwanted birth. Thus, we find that induced abortion is usually taken by Korean women for the purpose of limiting family size and spacing births as in any other countries. Premarital pregnancy and economic hardship are also important reason for taking an induced abortioin, especially for the first time abortion.

Objective : To evaluate luteinizing hormone (LH) in patients with infertility and recurrent spontaneous abortion. Material and Method: LH was tested by solid phase immunoradiometric assay based on monoclonal and polyclonal anti-LH antibodies. Results: Of 100 infertile patients, the number of less than 5 mIU/ml, 5$\sim$10 mIU/ml, greater than 10 mIU/ml in LH level was 67 (67%), 22 (22%), 11 (11%), respectively. Of 100 patients with recurrent spontaneous abortion, the number of less than 5 mIU/ml, 5$\sim$10 mIU/ml, greater than 10 mIU/ml in LH level was 79 (79%), 18 (18%), 3 (3%), respectively. There was a significant difference between patients with infertility and recurrent spontaneous abortion only in the group with LH level greater than 10 mIU/ml (p=.0325). Conclusions: High LH in the follicular phase is known to decrease pregnancy rate and increase abortion rate. But in this study the incidence of high LH in patients with recurrent spontaneous abortion was low. On the contrary, there was a significant increase of LH in infertile patients. So recurrent spontaneous abortion does not seem to be related to high LH level.
