Purpose: This study aimed to review recent findings from birth cohort studies on maternal and child environmental health. Methods: Birth cohort studies regarding environmental health outcomes for mothers and their children were investigated through a systematic review. A literature search was conducted in PubMed, CINAHL, the Cochrane Library, Embase, and RISS to identify published studies using the keywords using a combination of the following keywords: maternal exposure, environmental exposure, health, cohort, and birth cohort. Articles were searched and a quality appraisal using the Newcastle-Ottawa Scale for cohort studies was done. Results: A review of the 14 selected studies revealed that prenatal and early life exposure to environmental pollutants had negative impacts on physical, cognitive, and behavioral development among mothers and children up to 12 years later. Environmental pollutants included endocrine disruptors, air pollution (e.g., particulate matter), and heavy metals. Conclusion: This systematic review demonstrated that exposure to environmental pollutants negatively influences maternal and children's environmental health outcomes from pregnancy to the early years of life. Therefore, maternal health care professionals should take steps to reduce mothers' and children's exposure to environmental pollutants.

Purpose: This study was conducted to identify the effects of a lifestyle intervention program on weight gain, dietary habits, fatigue and pregnancy stress, blood pressure, and neonatal birth weight, using Cox's interaction model of client health behavior for overweight and obese women. Methods: This was a quasi-experimental research with a non-equivalent control group pre-post test design. A total of 52 patients who met the selection criteria, including 25 in the experimental group and 27 in the control group, were the subjects of the study; they comprised overweight and obese pregnant women who were receiving prenatal care at A and B women's hospital in J province. The lifestyle intervention program ran for 12 weeks in total and consisted of interactions involving affective support, health information, and professional/technical competencies. The data collection period was from February 1, 2017 to August 31, 2017. Results: This study showed differences in the appropriate weight gain rate (χ²=6.17, p=.013), suppression of an increase in fatigue (t=-2.32, p=.012), and an increase in pregnancy stress (t=-1.87, p=.034). Yet, no differences in physical activity, dietary habits change, blood pressure, and neonatal birth weight (p>.05) were found. Conclusion: The study findings indicate that this program could be an effective intervention for the control of appropriate weight gain, fatigue, and pregnancy stress. Therefore, a lifestyle intervention program based on Cox's interaction model of client health behavior could be an efficient strategy for a positive health outcome of overweight and obesity pregnant women.

This study was performed with, two groups of 369 pregnant women, which consisted of the first group of 186 pregnant women taking physical examinations for birth at the Korea clinic in Seoul during the months of November and December in 1972, and the second group of 183 pregnant women taking physical examinations for birth at the Kang Won Provincial Hospital for the 12 months from October, 1972 to September 1973, as the results of this study the following concussion was obtained. 1. Age distribution indicated that the group of 25 through 34 age among them fallen 76 percent. 2. The time of the first physical examination by the 76% pregnant women of the second group at Chun Chon was in the initial period of pregnancy, but the time of that by every 33% pregnant women of the first group in Seoul came to the initial, middle and late period of pregnancy, evenly. 3. The 65.6% of the second group had one or two times of physical examination and the 80% of the first group had one to eight times of physical examination. 4. The mean pregnancy times was 1.9 to the first group and 2.8 to the second group, showing high pregnancy rate in Seoul city- 5. The 57.3% of the first group and the 31.3% of the second group did one times of abortion. The 3.2% of the first group and the 10.7% of the second group did more then six times of abortion, this meant big difference between two groups. The 24.1% of the first group had four times of pregnancy and the 18.1% of the second group had three or four times of it. These percentages was the highest of all. 6. Death rate during the period of pregnancy was shown to be 3.2% to the first group and 9.7% to the second group, consequently indicating gre311y high death rate in local city. 7. Many of the first group have three children and some of the second group have seven children. 8. As to totemics of pregnancy, 23.7% of the first group, and 49.7% of the second group were shown to have totemics of pregnancy, consequently with greatly high totemics rate of pregnancy in local city. The 4.0% of the first group and 37.0% of the second group was short of hemoglobin, with remarkable difference between the two groups.

생활수준과 교육수준이 매우 낮은 저개발국가에서의 임신분만 환경을 알아보고 건강관련 행위 실천(산전진찰, 시설분만, 제대기구소독)과 지식과 태도와의 관계를 알아보기 위하여 네팔 돌카 마을에서 지난 1년간(1994년 4월 13일$\sim$1995년 4월 12일)출산한 경험이 있는 산모를 대상으로 일반적 특성, 임신과 분만에 관련된 지식, 태도, 산전진찰률, 분만환경 등을 조사하였다. 이 지역의 임신과 분만에 관련된 지식수준은 낮은 편으로 대상자의 87.5%가 보건교육을 받은 경험이 없었다. 대상자의 29.6%는 임신시 흡연이 태아에 해가 없다고 하였으며, 42.8%는 임신시 음주와 약의 복용이 태아에 해가 없다고 답하였고, 17.1%가 제대절단시 소독하지 않은 기구를 사용해도 유해하지 않다고 응답하였는데, 교육을 받은 적이 없는 경우, 보건교육을 받은 경험이 없는 경우, 그리고 보건기관까지의 거리가 멀 수록 올바르지 못한 지식을 가지고 있었다. 응답자의 56.6%가 산전진찰이 필요없다는 태도를 보였고, 42.8%가 질출혈시 병원을 방문할 필요가 없다는 태도를 보였는데, 교육을 받은 적이 없는 경우, 보건 교육을 받은 경험이 없는 경우, 그리고 보건기관까지의 거리가 멀수록 바람직하지 못한 태도를 가지고 있었다. 또한 82.9%가 분만과정 자체가 불결한 것이라고 여기고 있었다. 한번이라도 산전진찰을 받은 경험이 있는 산전진찰 경험률은 28.3%였는데 교육을 받은 적이 없는 경우, 보건교육을 받은 경험이 없는 경우에 산전진찰 미경험률이 높았다. 시설분만율은 5.3%로 매우 저조하였고, 시설 외 분만인 경우 82.6%가 제대절단기구를 소독하지 않고 사용하고 있었는데 교육을 받은 적이 없는 경우, 보건교육을 받은 경험이 없는 경우, 그리고 보건기관까지의 거리가 멀수록 소독을 하지 않고 사용하고 있었다. 지식과 태도와의 관계에 있어서는 지식이 많은 군이 산전진찰의 필요성을 더 느끼며 질출혈시 병원방문의 필요성을 더 느끼고 있어, 임신과 분만에 관련하여 더 바람직한 태도를 가지고 있었다. 태도와 실천과의 관계에 있어서는 바람직한 태도를 가진 산모군이 산전진찰 경험률이 높았으며, 시설분만이 많아 실천율이 높았다. 다변량 분석에서도 지식이 태도에 양(陽)의 영향을 미치는 변수였으며, 태도는 실천에 영향을 미치는 유의한 양(陽)의 변수여서 실천을 위해서는 긍정적인 태도가 선행되어야 하고, 그러기 위하여는 먼저 올바른 지식을 가지고 있어야 함을 알 수 있었다. 이상의 연구결과로 볼 때, 저개발국가에서의 분만환경은 매우 열악한 편으로 모자의 건강수준 향상을 위해서는 예방적 기능으로서 보건교육 활동이 더욱 중요 성을 가지게 된다. 효율적 보건교육활동을 위해서는 보건교육을 보다 긴요하게 요하는 인구군이 어떤 계층이냐 하는 대상파악에 특별히 유념하여야 하는데 주로 교육수준이 낮고 생활이 어려운 인구층, 그리고 보건기관으로부터 멀리 떨어져 있는 사람들에게 중점적으로 교육을 시도하여야 하겠는데 이들 나라는 대부분의 국민이 교육수준이 낮고 생활수준이 낮은 편으로 보건교육시 단순한 지식의 전달에 그칠 것이 아니라 동기 유발을 가져와 행위변화를 할 수 있도록 보다 세밀한 연구노력이 필요하다. 또한 순회진료와 보건교육을 하는 의료캠프가 활성화되어야 하겠다. 향후 저개발국에 의료단을 파견하여 그 지 역의 보건문제 해결에 도움을 주기 위하여는 이와 같은 연구가 계속 진행되어 실천에 영향을 주는 요인들을 밝혀 지역보건의료 프로그램에 적극 활용해야 할 것으로 생각된다.

For the flexible and rational distribution of limited existing health resources based on measurements of individual risk, the socalled Risk Approach is being proposed by the World Health Organization as a managerial tool in maternal and child health care program. This approach, in principle, puts us under the necessity of developing a technique by which we will be able to measure the degree of risk or to discriminate the future outcomes of pregnancy on the basis of prior information obtainable at prenatal care delivery settings. Numerous recent studies have focussed on the identification of relevant risk factors as the Prior infer mation and on defining the adverse outcomes of pregnancy to be dicriminated, and also have tried on how to develope scoring system of risk factors for the quantitative assessment of the factors as the determinant of pregnancy outcomes. Once the scoring system is established the technique of classifying the patients into with normal and with adverse outcomes will be easily de veloped. The scoring system should be developed to meet the following four basic requirements. 1) Easy to construct 2) Easy to use 3) To be theoretically sound 4) To be valid In searching for a feasible methodology which will meet these requirements, the author has attempted to apply the“Likelihood Method”, one of the well known principles in statistical analysis, to develop such scoring system according to the process as follows. Step 1. Classify the patients into four groups: Group $A_1$: With adverse outcomes on fetal (neonatal) side only. Group $A_2$: With adverse outcomes on maternal side only. Group $A_3$: With adverse outcome on both maternal and fetal (neonatal) sides. Group B: With normal outcomes. Step 2. Construct the marginal tabulation on the distribution of risk factors for each group. Step 3. For the calculation of risk score, take logarithmic transformation of relative proport-ions of the distribution and round them off to integers. Step 4. Test the validity of the score chart. h total of 2, 282 maternity records registered during the period of January 1, 1982-December 31, 1982 at Ewha Womans University Hospital were used for this study and the“Questionnaire for Maternity Record for Prenatal and Intrapartum High Risk Screening”developed by the Korean Institute for Population and Health was used to rearrange the information on the records into an easy analytic form. The findings of the study are summarized as follows. 1) The risk score chart constructed on the basis of“Likelihood Method”ispresented in Table 4 in the main text. 2) From the analysis of the risk score chart it was observed that a total of 24 risk factors could be identified as having significant predicting power for the discrimination of pregnancy outcomes into four groups as defined above. They are: (1) age (2) marital status (3) age at first pregnancy (4) medical insurance (5) number of pregnancies (6) history of Cesarean sections (7). number of living child (8) history of premature infants (9) history of over weighted new born (10) history of congenital anomalies (11) history of multiple pregnancies (12) history of abnormal presentation (13) history of obstetric abnormalities (14) past illness (15) hemoglobin level (16) blood pressure (17) heart status (18) general appearance (19) edema status (20) result of abdominal examination (21) cervix status (22) pelvis status (23) chief complaints (24) Reasons for examination 3) The validity of the score chart turned out to be as follows: a) Sensitivity: Group $A_1$: 0.75 Group $A_2$: 0.78 Group $A_3$: 0.92 All combined : 0.85 b) Specificity : 0.68 4) The diagnosabilities of the“score chart”for a set of hypothetical prevalence of adverse outcomes were calculated as follows (the sensitivity“for all combined”was used). Hypothetidal Prevalence : 5％ 10％ 20％ 30％ 40％ 50％ 60％ Diagnosability : 12% 23% 40% 53% 64% 75% 80%.

Objectives : DNA methylation is one of the best characterized epigenetic mechanisms that play a regulatory role in genome programming and imprinting during embryogenesis. In this present study, we investigated the association between DNA methylation in the human placenta and the maternal folate and homocysteine concentrations on the Methylenetetrahydrofolatereductase (MTHFR) genetic polymorphism during pregnancy. Methods : We investigated 107 pregnant women who visited Ewha Woman's University Hospital for prenatal care during their $24{\sim}28$ weeks-period of gestation. During the second trimester, we measured the serum homocysteine and folate concentrations . The MTHFR 677 genetic polymorphism was determine by performing PCR-RFLP assay. The expression of DNA methylation in the human placentas was estimated by using immunohistochemistry method. Results : Serum folate was negatively correlated with the serum homocysteine concentration for all the MTHFR genotypes. We found positive correlation between the folate concentrations and the DNA methylation in the human placenta (p<0.05). An increasing concentration of homocysteine was associated with reduced DNA methylation in the human placenta. The coefficient value was -2.03 (-3.77, -0.29) on the regression model (p<0.05). Conclusion : These findings suggest that the maternal folate and homocysteine levels along with the MTHFR 677 genetic polymorphism during pregnancy affect the DNA methylation in the human placenta.

Pregnancy is a task of creation in which a women mobilizes her self and the resources available to her in the generation of a new person. Through the pregnancy, a mother has formed the new human relationship with a fetus. Maternal-fetal relationship is considered one of mechanism making the relationship of mother and child. It is important to well-being of mother and fetus, too. The earliest interaction between a mother and her child is during prenatal period. Maternal-fetal dyad is unique and perceived interactions with the fetus make the pregnancy real for the mother. Maternal behavior is "instinctive" and is formed in early childhood by copy of the mother. But, Rubin argues that this behavior is an open intellectual system rather than a prepackaged bundle of traits. There is openness to new learning and a high value placed on knowing which occurs with silent organization in thought. Thus, nurses and other health professionals provide prenatal care that optimally is part of the environment in which the maternal-fetal dyad develops. Thus it is appropriate for nurses to increases their understanding of the dyad and to explore ways to enhance its development. This study focusses on the interaction ability and response of fetus, and the maternal-fetal interaction. The research of fetal responses that involve physiological changes and motor movement have been shown to coccur to both external sensory stimuli and to maternal emotional states. The fetus does also have sensory capacity to be aware of some maternal behaviors, and the motor ability to respond in a way the mother can notice. Thus, very rudimentary interactions appear to be possible. Maternal awareness of fetal activity was supported by several studies. More interesting to the present study are description of maternal-fetal interaction and the finding that there appear to be levels of sensitivity to the fetus involved in maternal-fetal interactions. First, recognition comes that the fetus is separate from the maternal self. Next, the fetus engages in. Lastly, the parent may describe active interaction with the fetus, believing that mother and fetus are communicating on a meaningful level. Several interventions, developed to promote more active interaction between mother and fetus, have been reviewed. In general, the parents were taught to stimulate the fetus and to notice the fetus' responses. This type of intervention might increase the mother's sensitivity to her unborn baby, and she may have a head start toward learning how to res pond sensitivity to the newborn infant. Research In the area of maternal-fetal interaction is scarce. Sensitive behavior is construed as an appropriate and timely response to a signal of need from another person, but no such signal of need can be claimed regarding the fetus. The highest level of maternal-fetal interaction, therefore, might be based more on maternal representations of the imagined fetus than on factual evidence of fetal participation.
