Ecological studies have indicated that the essential fatty acids in maternal and umbilical cord blood samples are associated with gestational length and birth weight. The objectives of this study were to examine serum fatty acid concentration, particularly $\omega$3 fatty acids, in maternal and umbilical cord blood and to investigate the relationship of serum fatty acid levels in the blood of the mother and of the umbilical cord. Subjects consisted of 30 full-term and 30 pre-term mothers and neonates of both groups. Serum levels of fatty acids were measured by gas chromatography. The concentration of total saturated fatty acids in pre-term pregnant women was significantly higher than that of the full-term group (p<0.05), however, the maternal level of $\omega$3 fatty acids in the pre-term group was significantly lower than that of the full-term pregnant women (p<0.05), Moreover, the concentrations of $\alpha$-linolenic acid and eicosapentaenoic acid in full-term pregnant women were significantly higher than those of the pre-term group. In umbilical cord blood, the levels of total $\omega$3 fatty acid and arachidonic acid were significantly lower in the pre-term group than in the full-term group (p<0.05). Based on the coefficient of correlation between serum fatty acids in the mother and the umbilical cord, it turned out that in the full-term group, the newborn's umbilical cord serum fatty acids were not influenced by the levels of serum fatty acids in the mother. However, in the pre-term group, it seems to have positive correlations in terms of the levels of SFA, MUFA, PUFA and $\alpha$-linolenic acid. This study suggests that a lower status of $\omega$3 fatty acids in maternal and umbilical cord blood probably is a risk factor for pre-term birth.

This study was performed to assess the relationships between bone mineral density(BMD), anthropometric measurements, and maternal factors in postmenopausal women. The anthropometric measurements were taken by a trained practitioner, and the maternal factors of the 85 subjects in Chungnam were acquired by an interview questionaire. The BMDs of the lumbar $spines(L_2-L_4)$, femoral necks(FN), ward's triangles(WT), and trochanters(TR) were measured by dual energy X-ray absorptiometry(DEXA). The BMDs(T-score) for $L_2-L_4$, FN, and WT were 0.996 $g/cm^2$(-1.601), 0.697 $g/cm^2(-1.657)$, and 0.793 $g/cm^2(-1.512)$ respectively, which were assessed as osteopenia by the T-score ; TR was noma1 at 0.718 $g/cm^2(-0.675)$. The 85 subjects in Chungnam were divided into three groups according to their BMD measurements for $L_2-L_4$ and FN, assessed by the T-score. The percentages in the osteoporosis, osteopenia, and normal groups were 32.9%, 42.4, and 24.7%, respectively. The average age was significantly the highest in the osteoporosis group than in the other two osteopenia and normal group(p<0.001). The subjects' BMDs were positively correlated with weight, height, BMI, waist, WHR, OBR and hip circumference, and negatively correlated with the age, duration time after menopause, lactation, the age of last delivery, menarche age, and number of children. The average age at menopause was 48.8. The osteoporosis group's average age at menopause was lower than those of the other groups. However, the BMD of the lumbar spine positively correlated with duration time after menopause and the BMD of the femoral neck with lactation, last delivery, menarch age, number of children. Therefore, researches are needed to find out the effective way to minimize the effect of age and other physiological conditions on the decrease of bone mass density.

This study was undertaken to investigate the association between maternal nutrition knowledge, dietary attitudes, and behaviors related to sugar intake and sugar intake reduction in preschool children. Eighty-three children aged 5 to 6 years attending kindergartens in Hongseong and their mothers participated in this study from October 2020 to February 2021. The average age of the mothers was 38.7 years, and 53.0% of the children were male. As child age increased, nutrition knowledge of sugar intake reduction increased, but no relation was found between age and, dietary behavior and preference related to sugar intake reduction. For children whose mothers perceived that their child's sugar preference was high, the behavioral score of sugar intake reduction was low. The more mothers allowed their children to eat sweet food; the higher was their child's preference for sweet food, which was also significantly associated with an increased risk of high sugar intake. When mothers were provided education that encouraged reducing children's sugar intakes, knowledge about reducing sugar intake in children was significantly increased. The study emphasizes the importance of the roles of mothers and primary caregivers regarding reducing the sugar intakes of preschool children.

Purpose: This study was done to explore and understand acculturation focusing on reproductive health of immigrant women. Methods: For the research sixteen immigrant women were selected by snowball sampling. Qualitative data were accumulated by in-depth interviews and private document collection. Raw data was analyzed following Mandelbaum's conceptual framework. Results: The dimensions of immigrant women consisted of existence: emerging from the new environment in which it was hard to communicate and to get acquainted with others, reproduction: in the absence of learning and experience, reproductive health crisis, parenting: unmanageable burden. Turnings of life involved 'Inconvenience in one's eyes, vent for conflict and tension: pregnancy', 'strange medical care: accoucheur, rapid medical service', 'pain of morning sickness: poor maternal nutrition', 'manifestation of protective instinct for life'. In adaptations, content was as follows. 1) Standing alone as a Korean housewife, 2) Becoming aware of Korean maternal instinct: thirst for education supporting, 3) Rediscovery of family: growing maternal sense of existence. Conclusion: The results of this study show the acculturation process and the meaning of events related to reproductive health in current lives and can contribute to an integrated understanding of married immigrant women in Korean culture.

This study was aimed at evaluating the lipid status of 122 pregnant women, who were attending peripheral community clinics in low-income areas and were vulnerable in terms of public health, by anthropometric measurements, estimating dietary intakes and analyzing serum lipids content and fatty acids composition. Regarding the skinfold thickness, it has increased more significantly in suprailliac than in triceps, biceps, subscapular, which means body fat has been accumulated in central parts more than in distal parts of the pregnants. It is found that intakes of energy, protein, lipid and carbohydrate are desirable while calcium, zinc and copper are low and sodium is excessive. Regarding dietary fat intake, the energy $\%$ of fat was within the same range as RDA(20%) for adults, but energy $\%$ intake from each fatty acid was usually low, especially energy % of monoun-saturated fatty acid intake was below RDA for adult women. And intake ratio of $\omega$6$\omega$3 fatty acids was desirable. Accordingly, it is thought that dietary fat intake was balanced in quality. Serum lipids concentrations were increased with the length of pregnancy and were higher as compared with non-pregnant women. Polyunsaturated fatty acids, especially $\omega$6 fatty acids, have gradually decreased with the length of pregnancy. Serum lipids content and fatty acids composition were not greatly influenced by dietary fat but serum free fatty acid level was negatively related to energy, carbohydrate, fatty acids and cholesterol intake. On the basis of the above results, it can be predicted that lipid metabolism for mother and fetus is changed by pregnant status and multilateral research on maternal nutrition in terms of areas and income levels will have to be made.

The purpose of this study was to examine the influence of maternal socioeconomic status, maternal oral health behaviors, and oral health behaviors of children, on the prevalence of early childhood caries in children aged 5 years. The Korean National Health and Nutrition Examination Survey data collected between 2007 and 2014 were applied to this study, and the study sample included 824 children who received oral examinations and participated in the health behavior survey. The factor that affected the prevalence of early childhood caries were confirmed by maternal and child factors. The data were analyzed using multiple linear regression. The mothers' age, income level, and job status affected the prevalence of early childhood caries. There was a significant difference in the analysis considering the factors of motherhood and children in the prevalence of early childhood caries according to mother's age, education level, income level, and the child's oral examination. The prevalence of early childhood caries was higher in children who received oral examinations than in those who did not. When the mother's educational level was higher than college education, it was found that the index of child, i.e., there was a difference in the prevalence of early childhood caries according to the mother's educational and income levels. These results indicate that maternal socioeconomic characteristics are correlated with the oral health of children. Therefore, oral health education programs that include mothers for the prevention of early dental caries in children may improve the dental health of children. In addition, specific oral health policies are necessary to address the differences in the oral health between the income groups.

BACKGROUND/OBJECTIVES: This study aimed to identify preschool children's eating behaviors associated with early childhood obesity and its multi-level, socio-ecological determinants. SUBJECTS/METHODS: In a cross-sectional study of 364 mothers of preschool children aged 3-5 years, these children's healthy eating behaviors were assessed using a validated preschool nutrition quotient (NQ-P) questionnaire. The children's overweight or obesity statuses were determined based on body mass index percentiles from the 2017 Korean National Growth Chart. The associations between the NQ-P score and risk of overweight or obesity were examined using multivariable logistic regression. The associations of individual, maternal, physical, and media environmental factors with the NQ-P score were also examined using multivariable linear regression. RESULTS: Preschool children with greater NQ-P scores were at a significantly lower risk of overweight or obesity (P < 0.01). The NQ-P score had a significantly positive association with maternal body mass index and an inverse association with household income (all P < 0.05). Maternal parenting and feeding practices exhibited associations with the NQ-P score. Positive associations were observed with "warm," "structured," and "autonomy-supportive" parenting as well as monitoring feeding practices (all P < 0.05). In addition, the NQ-P score had a significantly positive association with the childcare center's anti-obesogenic environment, such as the provision of nutritional and physical-activity support and vicinity of the built food environment to the home, including access to good-quality food, fruits and vegetables, and low-fat foods (all P < 0.05). Regarding media environments, the NQ-P score demonstrated more significant associations with viewing and eating and/or cooking content displayed on online video platforms (all P < 0.05) than with that on television. CONCLUSIONS: Our findings confirm the significance of healthy eating behaviors in early-childhood-obesity prevention and underscore the importance of multilevel maternal, physical, and media environmental interventions that effectively guide eating behaviors in preschool children.
