Purpose: This study was to identify relationships of maternal psychosocial factors including mother's mood state, childcare stress, social support and sleep satisfaction with breastfeeding adaptation and immune substances in breast milk, especially secretory immunoglobulin A (sIgA) and transforming growth factor-beta 2 (TGF-${\beta}2$). Methods: Data were collected from 84 mothers who delivered full-term infants by natural childbirth. Structured questionnaires and breast milk were collected at 2~4 days and 6 weeks postpartum. Data were analyzed using descriptive statistics, Pearson's correlation, multiple linear regression, and generalized estimating equation (GEE). Results: Scores for the breastfeeding adaptation scale were significantly related with child care stress, mood state and social support. Mother's anger was positively correlated with the level of sIgA in colostrum (p<.01). Immune substances of breastmilk was significantly influenced by time for milk collection (p<.001) and the type of breastfeeding (sIgA, p<.001, TGF-${\beta}2$, p=.003). Regression analysis showed that breastfeeding adaptation could be explained 59.1% by the type of breastfeeding, childcare stress, the Profile of Mood States, emotional support and sleep quality (F=16.67, p<.001). Conclusion: The findings from this study provide important concepts of breastfeeding adaptation program and explanation of psychosocial factors by immune substances in breast milk. Future research, specially, bio-maker research on breast milk should focus on the ways to improve breastfeeding adaptation.

BACKGROUND/OBJECTIVES: Proper nutrition intake during pregnancy and lactation is very important to both mothers and babies. Pregnant women should maintain proper nutritional status to restore decreased physical strength due to pregnancy and childbirth and produce breastmilk for the growth and development of the baby. Recently, the number of Chinese people living in Korea has increased as the exchange between Korea and China becomes active. It is important to provide proper nutrition education for pregnant women of both countries considering cultural differences. SUBJECTS/METHODS: The subjects of this study were postpartum women in Gyeonggi, South Korea and Jinhua, China. The subjects were 20-45 years old less than six months after childbirth. A survey, using self-administered questionnaires, was conducted from October 2018 to January 2019. For data analysis, 221 Korean postpartum women (KPW) and 221 Chinese postpartum women (CPW) questionnaires were used. RESULTS: KPW had significantly higher nutritional knowledge score and dietary attitude score than CPW (P < 0.001). However, overall score for dietary habits was significantly higher in CPW compared to KPW (P < 0.001). In KPW, nutritional knowledge (P < 0.01) and dietary attitude (P < 0.001) had significantly positive correlations with dietary habits. The proportions of KPW and CPW who answered that they had experience of nutrition education were 28.5% and 80.1% (P < 0.001). The score for dietary habits was lower as the hours for watching TV and using mobile phone became longer in postpartum women of both countries, with significant differences in KPW (P < 0.001) and CPW (P < 0.05). In KPW, the score for dietary habits in postpartum women with exercise experience was significantly higher than that in postpartum women without exercise experience (P < 0.001). CONCLUSIONS: More pregnancy-related nutrition education should be provided and various and effective nutrition education programs, which not only transfer information but can be practiced in the actual life, should be developed.

Purpose: 1. To analyze the satisfaction and cognition of postpartum care and to aid the spread of oriental medicine in postpartum care. 2. Get a basic guideline of O.M.D's postpartum care. Methods: We studied the satisfaction and cognition of postpartum care with questionnaire from January 2009 to August 2009, who was treated in ○○ Oriental Medical Postpartum care center during 2 weeks. 61 puerperants answered us. Results: 1. In choosing Postpartum care center, puerperants concerned about new born infants' care(50.8%) and treatment for discomfort after delivery(27.86%). 2. 22 puerperants(36.6%) had a positive view in folk remedy for postpartum care and 34 puerperants(55.73%) thought it would be good to eliminate edema and loose weight. 3. Most of puerperants(80.32%) chose oriental medical postpartum care because they wanted to receive oriental medical treatment. 4. 5 puerperants(8.19%) were very satisfied with oriental medical postpartum care than other type of postparum care which they experienced at first delivery. 47(77.04%) were satisfied, 2(3.27%) were unsatisfied and no one was very satisfied. 5. To the questionnaire about the effect of strength recovery, lochia excretion, edema limination, increasing amount of breastmilk, reducing arthralgia, about 36.8% puerperants showed positive view. 6. The positive view about Acupuncture, cupping, moxibustion, herbal treatment was, respectively, 90.16%, 49.18%, 73.77%, 86.88%. Conclusion: Puerperants were satisfied with oriental medical postpartum care and had positive cognition in oriental medical treatment. There is much capability for extension of oriental medicine in postpartum care. So continuous concern, systemic development and publicity about oriental medical postpartum care are required.

Purpose: Exclusive breastfeeding promotes gut microbial compositions associated with lower rates of metabolic and autoimmune diseases. Its cessation is implicated in increased microbiome-metabolome discordance, suggesting a vulnerability to dietary changes. Formula supplementation is common within our low-income, ethnic-minority community. We studied exclusively breastfed (EBF) neonates' early microbiome-metabolome coupling in efforts to build foundational knowledge needed to target this inequality. Methods: Maternal surveys and stool samples from seven EBF neonates at first transitional stool (0-24 hours), discharge (30-48 hours), and at first appointment (days 3-5) were collected. Survey included demographics, feeding method, medications, medical history and tobacco and alcohol use. Stool samples were processed for 16S rRNA gene sequencing and lipid analysis by gas chromatography-mass spectrometry. Alpha and beta diversity analyses and Procrustes randomization for associations were carried out. Results: Firmicutes, Proteobacteria, Bacteroidetes and Actinobacteria were the most abundant taxa. Variation in microbiome composition was greater between individuals than within (p=0.001). Palmitic, oleic, stearic, and linoleic acids were the most abundant lipids. Variation in lipid composition was greater between individuals than within (p=0.040). Multivariate composition of the metabolome, but not microbiome, correlated with time (p=0.030). Total lipids, saturated lipids, and unsaturated lipids concentrations increased over time (p=0.012, p=0.008, p=0.023). Alpha diversity did not correlate with time (p=0.403). Microbiome composition was not associated with each samples' metabolome (p=0.450). Conclusion: Neonate gut microbiomes were unique to each neonate; respective metabolome profiles demonstrated generalizable temporal developments. The overall variability suggests potential interplay between influences including maternal breastmilk composition, amount consumed and living environment.

Flame retardants are added to prevent catching fire and to slow down the burning process. PBDEs are known to affect thyroid hormones and hormone disruption. The aim of this study was to propose a manual for determination of PBDEs, and investigate the accumulation of PBDEs(BDE-28, 47, 99, 100, 153, 154 and 183) in fish&shellfish and human milk samples. Pre-treatment for PBDEs determination, alkali digestion and L-L(Liquid-Liquid) extraction method could be applied to fish and shellfish. When Multi-layer column was used for cleaning up the sample, 50 mL of hexane and 100 mL of hexane:dichloromethane(9:1) solutions were used for pre- and post-elution, respectively. Activated-carbon column was optimized by a 100 mL of hexane:dichloromethane(3:1). The result of fish, highest concentration was detected in flatfish, 890 pg/g(wet weight). The other side, lowest concentration was detected in pollack, 40 pg/g(wet weight). The result of breast milk, PBDEs was detected 2,580 and 3,600 pg/g(lipid weight) from breast milk of Seoul and Juju, respectively. BDE-153 and 183 were not detected in all samples. There was no difference in PBDEs level was not difference between first and second delivery. In this study, we could find that PBDEs level in Korea is lower than other countries.

The purpose of this study is to provide basic data regarding effective learning opportunities in childbirth education classes. Also analysis of the data indicates the optimum conditions for the welfare and improvements in the promotion of health in childbearing mothers. The results of this study are as follows; 1) The average age of the subjects in this study was 30.6 years and the total number of subjects was 58 pregnant women. The average number of children was one and 84.5% of the subjects were unemployed even though 63.8% of them held over bachelor's degrees. It was found that 22.4% of the subjects were living in an extended family. Also 61.5% of them were living with parents-in-law. The number of pregnancies were calssified as one, two, or three to nine times with the percentages of 58.7%, 22.4% and 18.9%, respectively. Further, 72.4% of the subjects had no abortion experience and 15.5% had one aborion experience. While 89.7% of the subjects planned to feed their babies with breastmilk, mixed feeding were used by only 22.4% of the sample. These data were collected at about 6 months after delivery. Thus one can see that a low rate of breastfeeding was common. 2) The length of one period of childbirth education is four weeks. It was found that 36.2% of the subjects participated in childbirth education only once, where as 13.8% participated four times and 19% of the subjects participated in this class more than four times. pregnant at least once. Further, 75.9% of the participants were participated in this education through their own will. Their motivation for participation developed through information, advertisement and posters which contained information on childbirth education. Those with unplanned pregnancies 92.9% participated after a suggestion by the nurses. The number of participants in terms of percentage according to the childbirth education contents can be classified as following. The most active participation was shown in preparation of delivery(77.6%), postpartrm management(56.9%) fetal development(37.6%) and physiology of pregnancy(17.2%). It was found that 75.9% of the subjects were willing to participate again if they were given a chance. The reason can be summarized as following: The content of the education is very helpful(47.7%). Scientific knowledge can be obtained through this program(20.5%). Participation helps in achieving psychological stability(9.1%). Participation enables one to establish a friendly relationship with other participants(6.8%) of the sample. 24.1% of the participants did not want to participate again. The reasons can be as following: They do not want another baby(42.9%). The first paricipation in childbirth education gave enough knowledge about childbirth(21.4%). Another reason for not want to participate again was because they had a cesarean birth(14.3%). Only 7.1% of them responded with a negative view. A response that they do not need childbirth education after their operation can be traced back to the general belief that childbirth education is the place where one prepares for natural birth through the Lamaze breathing technique. Of the subjects, 91.4% suggested that this program could be recommended to other childbearing mothers, because this program gave educational content along with psychological stability for childbearing women. Of the subjects 41.4% did not see any efforts towards the welfare of the baby, where as 88.2% did. Among the subjects 58.6% made some effort to eliminate the discomfort of labor by breathing and imagination and breathing and walking. Further 41.7% of the 24 subjects did not do anything toward the welfare of the baby, because they did have a cesarean section so that they didn't have a chance even though they had been educated about childbirth. Also 33.3% of the subjects did not do anything toward the welfare of the baby, because they lacked a willingness. After leaving the hospital, only 75.9% of the subjects did some exercises. The subjects who tried participate this program with their husband accounted for 20.7% of the sample. Interviewing with the subjects solved some of the uneasiness and. fear of delivery, increased self-confidence in parenting and active coping in the delivery process.
