Objectives : To investigate the effect of parents' social class on infant and child mortality rates among the birth cohort, for the period of transition to and from the Koran economic crisis 1995-2004. Methods : All births reported to between 1995 and 2004 (n=5,711,337) were analyzed using a Cox regression model, to study the role of the social determinants of parents in infant and child mortality. The results were adjusted for the parents' age, education and occupation, together with mother's obstetrical history. Results. The crude death rate among those under 10 was 3.71 per 1000 births (21,217 deaths among 5,711,337 births) between 1995 and 2004. The birth cohorts from lower educated parents less than elementary school showed higher mortality rates compared with those from higher educated parents over university level (HR:3.0 (95%CI:2.8-3.7) for father and HR:3.4 (95%CI:3.3-4.5) for mother). The mother's education level showed a stronger relationship with mortality among the birth cohort than that of the fathers. The gaps in infant mortality rates by parents' social class, and educational level became wider from 1995 to 2004. In particular, the breadth of the existing gap between higher and lower parents' social class groups has dramatically widened since the economic crisis of 1998. Discussions : This study shows that social differences exist in infant and child mortality rates. Also, the gap for the infant mortality due to social class has become wider since the economic crisis of 1998.

이 연구의 목적은 사망수준의 저하에 영향을 미치는 세 요소-사회경제적 발전, 공공 보건의 발달, 사회경제적 발달의 균등상태-의 상대적 중요성을 분석하는 것이다. 종속변수인 사망 수준의 지표로는 영아사망률과 출생시 기대수명 등 두 변수가 사용되었다. 국민총생산(GNP)은 사회 경제적 발달지표로 여성의 초등학교 취학률과 기니계수(GINI index)는 사회경제적 균등상태 지표로 병원침대당 인구수는 공공보건 지표로 간주되었다. 변수들에 대한 자료는 두 시점에 걸쳐 수집되었다. 하나는 1970년 이전 53개국에서. 다른 하나는 1970-80년대 55개국에서 수집되었다. 탐색적 자료 분석 방법이 통계 분석 방법으로 사용되었다. 이 기법은 종속변수와 독립변수와의 관계가 선형인지 아닌지, 그리고 우리 모형에서 어느 것이 유력 사례인지를 파악할 수 있는 장점이 있다. 분석결과에 따르면, 첫째로 영아 사망률과 세 요소의 관계가 선형이 아니라 비선형임이 밝혀졌다. 영아 사망률 저하에 국민총생산이 가장 많이, 여성의 초등학교 취학률이 두 번째, 기니계수가 그 다음으로 영향을 미치는 것으로 나타났다. 반면 병원침대당 인구수는 통계적으로 유의미한 영향을 보여주지 않았다. 둘째, 출생시 기대수명은 여성의 취학률, 기니계수 등과 같은 변수와는 선형 관계를 가지는 반면 국민총생산 변수와는 비선형 관계를 가진다. 영아사망률 변수와는 달리 출생시 기대수명의 변이에는 여성의 초등학교 취학률이 국민총생산보다 더 커다란 영향을 미쳤다.

Purpose: This study aimed to identify maternal, infant, and perinatal mortality using the national population data of South Korea between 2018 and 2020, and to analyze mortality rates according to characteristics such as age, date of death, and cause of death in each group. This study updates the most recent study using 2009 to 2017 data. Methods: Analyses of maternal, infant, and perinatal mortality were done with data identified through the supplementary investigation system for cases of death from the Census of Population Dynamics data provided by Statistics Korea from 2018 to 2020. Results: Between 2018 and 2020, a total of 99 maternal deaths, 2,427 infant deaths, and 2,408 perinatal deaths were identified from 901,835 live births. The maternal mortality ratio was 11.3 deaths per 100,000 live births in 2018; it decreased to 9.9 in 2019 but increased again to 11.8 in 2020. The maternal mortality ratio increased steeply in women over the age of 40 years. An increasing trend in the maternal mortality ratio was found for complications related to the puerperium and hypertensive disorders. Both infant and perinatal mortality continued to decrease, from 2.8 deaths per 1,000 live births in 2018 to 2.5 in 2020 and from 2.8 in 2018 to 2.5 in 2020, respectively. Conclusion: Overall, the maternal, infant, and perinatal mortality statistics showed improvements. However, more attention should be paid to women over 40 years of age and specific causes of maternal deaths, which should be taken into account in Korea's maternal and child health policies.

In recent years, Korea has experienced a steadily declining birth rate, which is a serious social problem in the country. Although living conditions have improved, the birth rates for low birth weight infants and preterm babies has increased because more and more women choose to give birth later in life and the social environment has changed. The rise in low birth weight infants may increase infant mortality rates and morbidity rates. However, the recent improvements in neonatal care has elevated the survival rate of low birth weight infants up to 90 percent and lowered the weight of the very low birth weight infants that can now be saved. In this study, we used dynamic population statistics from the Korea National Statistical Office, which represents the current trend of social stratification and the population of this period. We analyzed birth records for a seven-year period and studied the changes in the delivery rate of preterm and low birth weight infants and the problems related to those changes. The results show that the rate of low birth weight infants has increased from 3.79% to 4.35% for the past seven years. The rate of preterm babies rose from 3.79% to 4.89%. The number of babies born from mothers aged 35 or more went up from 6.69% to 11.83% of the total number of the babies born. As maternal age has risen, the risks of delivering a preterm or low birth weight infant have also increased.

Purpose: Sudden unexplained infant death (SUID) is a major contributor to infant mortality, and pediatric nurses have the responsibility to educate parents on SUID-reducing strategies. This study was conducted to measure pediatric nurses' knowledge of SUID-related safe sleep practices (K-SSSP) and infant cardiopulmonary resuscitation (K-ICPR). Methods: In total, 136 pediatric nurses were administered a survey including K-SSSP (13 items), K-ICPR (5 items), confidence in K-SSSP education (1 item; 5 points), and other factors relating to SUID experiences or education. Results: The correct answer rates of the K-SSSP and K-ICPR were 62.6% and 62.5%, retrospectively. The mean score for confidence in K-SSSP education was 2.6±0.9. Only 18 nurses (13.2%) responded that they educated parents on the content of the K-SSSP, while 76 nurses had received education on SUID. Positive relationships were observed between K-SSSP scores and higher education, between K-ICPR scores and having own child(ren) and clinical experience, and between confidence in K-SSSP education and higher education or having one's own child(ren). Nurses caring for newborns performed more SUID education than nurses working in other units. Conclusion: There is a profound need to implement a systemic educational program on SUID and strategies to reduce SUID for pediatric nurses.

This study shows trends and age-sex patterns of mortality in Korea, based on adjusted death registration data during 1956∼1980. Description on the data-the types of errors and their methods of adjustment-are presented elsewhere (Kim, 1986). Crude death rates have declined in 20 years to 7.0 in 1976∼1980, almost half the level of 13.0 in 1956∼1960. Mortality of females declined faster than males, especially at older ages. Substantial differences in provincial mortality are observed based on the expectation of life at birth. The difference between the highest and the lowest provinces is 9.2 years for males and 8.3 years for females during 1976∼1980. This study presents two interesting features of age-sex patterns of mortality in Korea. One feature is higher female mortality than males during childhood periods. However, infant mortality is higher for males than for females throughout the period, though the difference is much smaller than is expected from various model life tables. Another feature is the rapid rise in mortality for males after age 40. This pattern is found to be existed throughout the period 1956∼1980. Further studies are recommended to establish its causal linkage to traditional sex role (as main bread winner) and health behavior (smoking and drinking) of males and recent rapid industrialization in Korea.

Purpose: Common conditions, such as dehydration or respiratory infection can aggravate hypoxia and are associated with interstage mortality in infants who have undergone palliative surgery for congenital heart diseases. This study was done to evaluate the efficacy of a home monitoring program (HMP) in decreasing infant mortality. Methods: Since its inception in May 2010, all infants who have undergone palliative surgery have been enrolled in HMP. This study was a prospective observational study and infant outcomes during HMP were compared with those of previous comparison groups. Parents were trained to measure oxygen saturation, body weight and feeding volume and to contact the hospital through the hotline for emergency situations. Telephone counseling was conducted by clinical nurse specialists every week post discharge. Results: Forty-one infants were enrolled in HMP. Nine hundred telephone counseling sessions were conducted. Seventy-three infants required telephone triage with the most common conditions being gastrointestinal (50.7%) and respiratory symptoms (32.9%). With HMP intervention, interstage mortality decreased from 18.6% (8/43) to 9.8% (4/41) (${\chi}^2$=1.15, p=.283). Conclusion: Results indicate that active measures and treatments using the HMP decrease mortality rates, however further investigation is required to identify various factors that contribute to hemodynamic complications during the interstage period.

A review has been made of mortality trends in Korea from 1958 to 1967 analyzing the data by sex, age and cause of death. The crude death rates and age specific death rates were estimated by the model of N. Keyfitz life table which had been developed by the data of the 1960's national census. The cause specific death rates shown in this article are based on the following: all deaths occurring in the death-registration are expressed as a numberator, while the denominator was estimated from the regular national census data by interpolation method. It is estimated that only an average of about 40% of deaths which occurred during a year were registered during 1958 to 1967. The validity and the reliability of the diagnosis of causes of death seem to be extremely poor in this country. Therefore the cause specific death rates in this article are aimed to reveal trends of causes of registered death ana not for the actual level of death rates. For 10 years very interesing mortality trends were observed : 1. The trend in the crude death rates was downward slowly. 2. The estimated death rate for the infant in 1960 was still high up to 100 per 1,000. 3. The rates for mortality attributed to such infectious diseases as pneumonia, bronchitis, gastroenteritis and measles decreased an average 40-60%. 4. The death rates for over-all tuberculosis decreased only 9.8%. 90% of the decrease was contributed by those in the less-than-15 year age group. 5. The death rates for chronic diseases, such as vascular diseases affecting the central nervous system, malignant neoplasm, major heart diseases and all accidents rose about 40-60%. 6. The rank order of the 10 leading causes of death showed large changes over the years, except for pneumonia and tuberculosis which occupyed 1st and 2nd places respectively. Vascular diseases affecting the central nervous system moved from 5th to 3rd place and malignant neoplasm from 6th to 4th place, The major heart diseases moved from 10th to 6th place and all accidents from 10th to 7th place. On tile other hand, gastroenteritis moved from 3rd to 5th place and influenja from 4th to 8th place.

The first life tables of the Korean, the so-called Chosun Joomin Saengmyong_Pyo were constructed by Misusima, the head professor, and his faculty members of Preventive Medicine Department, Division of Medical Science, Keijo Imperial University in 1937. The above mentioned life tables were based on the age specific mortality rates by the resident registration and the data of a couple of total population censuses conducted by the Governor of Chosun Government General in 1925 and 1930. And they revealed the following facts: (1) by the first Abridged Life Tables of Korean(Chosunin), the expected life span of Korean male and female were 32 and 35 from 1925 to 1930, respectively. (2) the infant mortality rate of Korean male and female were 252- and 230-person among 1000-born respectively. In conclusion, nobody knows the level of those Life Tables, but it is important in terms of that they are the origin of Korean life tables.
