Maternal stress was very common symptom that every pregnant women could have experienced during pregnant period. We found that the causative factors of stress for subjects were physical change(50.8%), family relationship(13.6%), change of body image(7.4%), concern baby(6.8%), economic difficulties(6.4%), depress(4.3%), morning sickness(3%), and miscellaneous(3.5%). According to our study, maternal stress during the first trimester negatively correlated with food and nutrients intake of pregnant women and gave low weight gain during pregnancy and low birth weight of infants. It also significantly correlated with monthly income(p<0.001) and monthly food cost(p<0.001) during pregnant period. Mean intake of Calcium and Iron were $47{\sim}60%$ of RDA and $35{\sim}48$ of RDA, respectively. With the Iron supplement the total intake of Iron exceeded 100% of RDA. We also found majority of food items, except seaweeds, fruits and vegetables, were negatively correlated with maternal stress during three trimesters. Additional support system projected by professionals in health-care field could mediate maternal stress and lead to healthy pregnancy outcome.

This study examines the relationship between mother's stress and cortisol level during late pregnancy and how it changes into postpartum periods. Thirty one families were recruited from Daejeon and Incheon in South Korea. The major findings were as follows: (1) The level of mothers' cortisol followed the typical diurnal pattern of decline throughout the day. Further longitudinal analysis revealed that the level of Korean mothers' cortisol steadily lowered from the 8th prenatal month to the 6th postnatal month. (2) During pregnancy, mothers reported to experience changes in physical activities, daily routines, eating habits, types or amount of social activities and sleeping habits. Among these they were stressed the most by changes in physical activities and social activities. (3) The results of postpartum depression tests conducted at two months after giving birth showed mothers at this time were mostly stressed from difficulty sleeping and unnecessary self criticism. (4) The level of psycho social stress in mothers at six months after giving birth was mainly on social roles and the questions about self reliance marked the highest points. (5) Overall, there was a tendency for the level of maternal stress to decrease definitely from before and after the delivery and even though the level of stress was steadily decreasing up to 6th postpartum month it was not as sharp as those of before and after the birth of the babies. The level of cortisol analysis also showed the same obvious tendency.

스트레스란, 개인과 환경간의 특별한 관계가 개인의 안녕을 위협하고 개인이 가진 자원을 초과하는 것을 말한다. 븐 연구는 청소년 임신과 스트레스에 관한 문헌연구를 통하여 청소년 임신과스트레스와의 관계에 대해서 살펴봄으로써 임신력 있는 청소년들을 위한 스트레스 관련 임상사회 사업 서비스 개입 방안을 제시하고자 하는데 목적이 있다. 임신으로 인한 부모됨의 변화가 청소년기 자체의 인생 주기 상에서의 스트레스와 중복될 때, 누적된 스트레스는 보다 커진다. 변화의 중첩은 개인 역할의 애매함을 초래하여 스트레스를 가중시키고 발달 과업의 우선순위에 혼란을 가져온다. 청소년기의 임신은 성인기로 이동하는 청소년 당사자, 그 자녀, 사회이 부정적인 영향을 미친다. 이러한 부정적인 영향은 단기간에 끝나지 않으므로 임신한 청소년들의 대처 기술과 적응력을 향상시키기 위한 개입의 노력이 필요하다. 임신한 청소년들의 경우에는 개인 상담 접근만으로는 불충분하며 효과적인 예방 프로그램은 보다 나은 대안이자 동시에 목적이 될 수 있다. 이러한 개입은 임신한 청소년들을 출산 이후에 노출되기 쉬운 디스트레스로부터 보호해주고 성인으로 성장하게 될 청소년들의 건강한 정신건강 도모이 기여하는 것으로 나파났다. 이는 결국, 임신한 청소년들을 대상으로 한 스트레스 대처 능력을 향상시키고 긍정적인 인지를 발달시킬 수 있는 스트레스 관리 프로그램의 필요성을 암시하고 있다. 이러한 연구 결과가 갖는 결론과 함께 앞으로 실천적 개입방안에 대한 더욱 정교한 연구가 요구된다.

Objectives: The purpose of this study is to investigate the perception of Korean Medicine (KM) doctors toward infertility treatment evaluation tools and develop a standard evaluation tool for mental and physical function improvement following Korean medicine treatment. Methods: An online survey (Moaform) was conducted, and responses were analyzed for members of the Society of Korean Medicine Obstetrics and Gynecology and KM doctors who participated in the 2021-2022 traditional Korean medicine treatment infertility support program in Gyeonggi-do. Results: In fertility treatment, the most effective indicators that KM doctors wanted to evaluate other than pregnancy and childbirth were reproductive health indicators, overall health improvement, and stress improvement (33.1%, 21.2%, 18.9%). Furthermore, 45.1% of the respondents had experience using the presented infertility stress evaluation tools. For each evaluation tool, 52.1% and 54.6% of the respondents answered that it 'does not reflect the changing circumstances of the times' and that there were 'too many questions'. As for the developing a standard evaluation tool for infertility treatment in KM, KM doctors expected a simple and clear tool focusing on the pregnancy rate. They also wanted the tool to include a reproductive health index, overall function improvement and stress improvements. Conclusions: The survey confirmed the need to evaluate indicators for reproductive health, mental health, and infertility stress in addition to pregnancy rate to assess the effectiveness of KM infertility treatment. It also confirms the necessity of developing an infertility stress evaluation tool with simplified questions that reflects the changing time.

본 연구는 임신기 동안 어미쥐의 철 섭취 수준이 모체의 철 대사지표와 산화적 스트레스 및 임신의 결과에 미치는 영향을 검토하기 위해 비임신쥐를 대조군으로 하여 수행하였다. 10주령 200 g 이상 된 암컷과 수컷 흰쥐를 1 : 1로 교배시켜 임신을 확인한 후, 비임신쥐 (대조군)와 임신쥐 (실험군)에게 식이 중 철 수준이 정상수준 (AIN-93G diet 수준, 35 mg Fe/kg diet), 고수준 (정상의 10배, 350 mg Fe/kg diet) 및 과잉수준 (정상의 30배, 1,050 mg Fe/kg diet)의 3가지 실험식이를 급여하였다. 임신 19일째 되는 날, 비임신쥐와 임신 쥐를 희생시켜 분석한 결과는 다음과 같다. 체중의 증가나 식이섭취량은 철 섭취 수준의 영향을 받지 않았고, 임신의 결과로서 태아의 수, 태아체중 및 태반무게도 철 섭취 수준의 영향은 받지 않았다. 헤모글로빈, 헤마토크릿, 혈청 철 농도 등의 혈액지표들은 철 섭취 수준의 영향은 받지 않았으나 임신에 의한 감소 경향을 보였다. 임신쥐의 철 섭취 수준의 증가에 따라 간과 지라 조직의 철 함량이 유의적으로 증가하였다. 또한 임신쥐의 간에서 페리틴 단백질 수준이 철 섭취의 증가에 따라 현저히 증가하였다. 산화적 손상지표인 지질과산화물 (MDA)은 철 섭취수준의 영향을 받지 않았고, 단백질 산화물 (protein carbonyls)은 비임신쥐와 임신쥐에서 모두 철 과잉 섭취군의 경우 유의적으로 증가하였다. 항산화효소 중에서는 철 과잉섭취군에서 간의 GPx 활성이 유의적으로 감소하였다. 결론적으로, 임신기 동안 어미쥐의 철 섭취수준의 증가는 어미쥐의 혈액지표와 임신의 결과에는 유의적인 영향을 미치지 않았지만, 간 조직 내 철 함량과 페리틴 단백질 수준을 유의적으로 증가시켰으며, 간 조직에서 단백질 산화물인 protein carbonyl 농도를 증가시키고, 항산화효소 중 특히 GPx의 활성 감소를 초래하였다. 또한 간 조직에서 세포사멸을 억제하는 중요한 인자인 Bcl-2 단백질 수준이 임신쥐에서 철 섭취의 증가에 따라 유의적으로 감소하였다. 이러한 영향이 철을 정상 수준의 10배 섭취한 군에서는 약하게 나타났으나, 30배 과잉으로 철을 섭취한 군에서는 유의적으로 차이를 보였다. 이 결과는 임신시 철 과잉 섭취의 해로운 영향이 지금까지 철 대사의 측정도구로 삼아왔던 혈액지표의 변화 보다는 체내에서 일어나는 조직의 산화적 스트레스의 증가나 조직 내 철의 축적 등에 보다 더 민감하게 반영됨을 알 수 있었다. 따라서, 철 과잉 섭취가 모체 뿐만 아니라 태생 조직의 산화적 스트레스에도 영향을 줄 수 있음을 시사하였다.

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.

본 연구는 HRV 신호를 분석하여 비임산부와 임산부의 시기별 자율신경계 활성도를 비교하였다. W병원의 질병이 없는 임산부 99명과 비임산부 27명을 연구대상으로 하였다. 획득한 HRV 신호는 프로그램을 이용해 시간영역 분석, 주파수 영역 분석을 실시하였다. 측정된 값은 일원배치 분산 분석을 통해 임신 시기별 간의 차이를 통계 분석 하였다. 결과에서, 시간 영역 분석에서 SDNN과 RMSSD는 임신 초기와 비임신 여성의 결과값이 임신 중기, 말기와 비교했을 때 유의하게 높았다. 주파수 영역 분석에서 LF와 HF는 임신 초기와 비임신의 값이 중기, 말기에 비하여 유의하게 높았으나 VLF와 LF/HF에서는 유의한 차이가 없었다. 이는 임신이 진행될수록 비임신 상태와 임신 초기보다 중기 및 말기에 자율신경 조절 능력이 저하되고 신체적 피로도와 정신적 피로도가 증가하게 되는 것을 의미한다. 따라서 임신 기간이 길어질수록 임산부의 심신 안정을 유지하기 위해 각별한 관리가 필요할 것으로 사료된다.

Pre-eclampsia (PE) is a pregnancy disorder that is characterised by severe hypertension and increased risks of foetal and maternal mortality. The aetiology of PE not completely understood; however, maternal nutrition and oxidative stress play important roles in the development of hypertension. The treatment options for PE are currently limited to anti-hypertensive drugs. Punicalagin, a polyphenol present in pomegranate juice, has a range of bioactive properties. The effects of supplementation with punicalagin on angiogenesis and oxidative stress in pregnant rats with induced hypertension were investigated. The pregnant rats were randomly divided into five experimental groups (n=12 per group). Hypertension was induced using an oral dose of NG-nitro-L-arginine methyl ester (L-NAME, 50 mg/kg/day) on days 14-19 of pregnancy. Punicalagin (25, 50 or 100 mg/kg) was given orally on days 14-21 of pregnancy. Punicalagin treatment at the tested doses significantly reduced diastolic, systolic, and mean arterial blood pressure in L-NAME treated rats from day 14. Punicalagin also restored angiogenic balance by increasing the expression of vascular endothelial growth factor and downregulating vascular endothelial growth factor receptor-1/fms-like tyrosine kinase-1. Punicalagin, significantly increased the placental nitric oxide levels as compared to PE group. The increased levels of oxidative stress in rats with PE were markedly decreased by treatment with punicalagin. Punicalagin at the tested doses markedly (p<0.05) enhanced the placental antioxidant capacity in L-NAME-treated rats. The raised catalase activity observed following L-NAME induction was significantly (p<0.05) and restored to normal activity levels in punicalagin treatment. Further, 100 mg dose of punicalagin exhibited higher protective effects as compared to lower doses of 25 and 50 mg. This study shows that supplementation with punicalagin decreased blood pressure and oxidative stress and restored angiogenic balance in pregnant rats with induced PE.

Purpose: To identify risk factors for premature birth among premature obstetric labor women. Methods: Participants were 129 hospitalized women who were diagnosed with potential premature obstetric labor with 20 weeks to 37 weeks of gestation. Data were analyzed using descriptive statistics, $x^2$ test, t-test, and binary logistic regression. Results: Of 129 women, 78(60.5%) gave premature birth and 51 (39.5%) gave full-term birth. Risk factors for premature birth were education level (${\leq}$bachelor's degree), abnormal bowel condition (constipation or diarrhea), time firstly diagnosed with a premature obstetric labor (below 28 weeks of pregnancy), and multiple pregnancy. There were also increased risks of premature birth for participants with high level of anxiety and high level of prenatal stress. In social support, there was an increased risk of premature birth for participants with low level of social support. Conclusion: Prenatal nursing programs should consider not only psychosocial factors such as anxiety, prenatal stress, and social support, but also some general and obstetric factors such as education level, abnormal bowel condition, time firstly diagnosed with a premature obstetric labor, and multiple pregnancy to increase maternal and child health.
