Background: Stunting is affected by various factors from mother and child. Previous studies assessed only one or more influencing variables. Unfortunately, nor the significant influence of maternal and child factors nor the indicators contributing to maternal and child factors that affect the stunting incidence have ever been analyzed. Purpose: This study analyzed the effect of maternal and child factors on stunting and the significant indicators that shape the maternal and child factors that impact stunting. Methods: This was a case-control study. Overall, 132 stunted children and 132 nonstunted children in Purbalingga Regency, Central Java Province, participated in the research. Direct interviews and medical record reviews were conducted to assess the studied variables. The research data were tested using the partial least squares structural equation with a formative model. Results: Maternal factors directly affected the occurrence of stunting (t=3.527, P<0.001) with an effect of 30.3%. Maternal factors also contributed a significant indirect effect on stunting through child factors (t=4.762, P<0.001) with an effect of 28.2%. Child factors affected the occurrence of stunting (t=5.749, P<0.001) with an effect of 49.8%. The child factor was influenced by maternal factor with an effect of 56.7% (t=10.014, P<0.001). The moderation analysis results demonstrated that maternal and child factors were moderate predictive variables of stunting occurrence. Conclusion: Child factors have more significant and direct effects on stunting than maternal factors but are greatly affected by them.

To investigate the effect of several factors on serum lipids in maternal and infants umbilical cord blood, 111 cases of newborn infants and women delivered of a child who had delivered at hospital located in Chung-Ju city from Feb. 1, 1996 to Aug. 31, 1996 were studied. The gestational ages of cases were 37 to 42 weeks and the average maternal ages were 28.1$\pm$4.25 years old without any other medical or obstetric problems. No relationships between maternal consumption of coffee and maternal serum lipid levels were observed. However, serum total cholesterol and LDL-cholesterol levels in infants'umbilical cord were significantly increased in proportion to increasing maternal consumption of coffee. The other factors such as alcohol drinking habits and residency affected maternal serum lipid levels and not serum lipid levels in infants' umbilical cord. Delivery frequency showed very little or no effects on serum lipid levels in both maternal blood and infant's umbilical cord blood. In conclusion, maternal consumption of coffee significantly correlated with increasement of serum lipid levels in infants'umbilical cord.

Purpose: Coronavirus disease 2019 (COVID-19) has spread widely throughout the world, causing psychological problems such as fear, anxiety, and stress. During the COVID-19 pandemic, pregnant women have been concerned about both their own health and the health of their fetuses, and these concerns could negatively affect maternal-fetal attachment. Thus, this study aimed to explore the level of COVID-19 stress, resilience, and maternal-fetal attachment among pregnant women during the COVID-19 pandemic, and to identify factors influencing maternal-fetal attachment. Methods: In total, 118 pregnant women past 20 weeks gestation were recruited from two maternity clinics in Daegu, Korea, to participate in this descriptive correlational study during COVID-19. The factors influencing maternal-fetal attachment were analyzed using hierarchical multiple regression analysis. Results: The mean scores for COVID-19 stress, resilience, and maternal-fetal attachment were 57.18±10.32 out of 84, 67.32±15.09 out of 100, and 77.23±9.00 out of 96, respectively. Nulliparous pregnant women reported greater maternal-fetal attachment than multiparous pregnant women (p=.003). Religious pregnant women also reported greater maternal-fetal attachment than non-religious pregnant women (p=.039). Resilience (β=.29, p=.002), COVID-19 stress (β=.20, p=.030) and parity (β=-.17, p=.047) were factors influencing maternal-fetal attachment, and these factors explained 26.4% of the variance in maternal-fetal attachment (F=10.12, p<.001). Conclusion: Converse to common sense, COVID-19 stress exerted a positive influence on maternal-fetal attachment in pregnant women during the COVID-19 pandemic. Healthcare providers need to recognize the positive influence of COVID-19 stress and implement intervention strategies to strengthen resilience in pregnant women to improve maternal-fetal attachment.

Purpose: This study was done to identify degrees of maternal conflict, differences, and factors predicting conflict in mothers of toddlers. Method: A convenience sample of 300 mothers living in G city, Kyounggi-do whose child was between 12 to 36 months old was used. Data were collected through a questionnaire survey and analyzed using SPSS WIN 10.0. Results: The average score for maternal conflict was 67.35 (SD=10.18), somewhat lower than moderate in level. 'I as a human being' was the area of the 6-sub areas with the most conflict. Mothers experiencing higher maternal conflict were those who were less satisfied with marriage, quality of life, and maternal role, and whose child was stubborn and hard to please, who were unsatisfied with baby sitters or who had to rush their sick child to hospital. Factors that were significant in predicting maternal conflict were low satisfaction with maternal role and marriage, and a child who was difficult to care for. These factors accounted for 22％ of explained variance. Conclusion: Nurses should help mothers resolve maternal conflict through education and counseling on the maternal role, but at the same time nurses should consider relationship of the mother with her husband and also special characteristics of her child.

Objective: This study examined the moderating effect of young children's temperament on the relationship between maternal anxiety and overprotection. Methods: A total of 250 mothers with 5-year-old children responded to online survey questionnaires, which included questions about maternal anxiety, overprotection, and their children's temperament. Results: The results of the study revealed several important findings. First, maternal anxiety had a positive correlation to the overall level of overprotection and all sub-factors. The correlation between young children's temperament and maternal overprotection had different results depending on the sub-factors of overprotection. Second, there was a significant moderating effect of young children's temperament on the relationship between maternal anxiety and overprotection. That is, When the reactivity of a child was low, the positive effect of maternal anxiety on maternal overprotection was greater. Looking at the sub-factors of overprotection, only reactive temperament showed a significant moderating effect in the relationship between maternal anxiety and intrusive overprotection. On the relationship between maternal anxiety and permissive overprotection, reactivity and adaptability had significant moderating effects. Conclusion/Implications: This study showed that mother's overprotection was associated with varying levels of their own anxiety and children's temperament. These findings offer basic knowledge for development of a program for improving parenting behaviors.

Stored maternal factors in oocytes regulate oocyte differentiation into embryos during early embryonic development. Before zygotic gene activation (ZGA), these early embryos are mainly dependent on maternal factors for survival, such as macromolecules and subcellular organelles in oocytes. The genes encoding these essential maternal products are referred to as maternal effect genes (MEGs). MEGs accumulate maternal factors during oogenesis and enable ZGA, progression of early embryo development, and the initial establishment of embryonic cell lineages. Disruption of MEGs results in defective embryogenesis. Despite their important functions, only a few mammalian MEGs have been identified. In this review we summarize the roles of known MEGs in mouse fertility, with a particular emphasis on oocytes and early embryonic development. An increased knowledge of the working mechanism of MEGs could ultimately provide a means to regulate oocyte maturation and subsequent early embryonic development.

The objective of this study was to examine the influence of anthropometric measurements of pregnant women, gestational weight gain, fundal height, and maternal factors, namely age, education, family income, parity along with maternal hemoglobin, on birth weight of neonates. A cross sectional study was performed in Khoy City in north west of Iran. Four hundred and fifty healthy pregnant women in the age between 16-40 years were selected for this study from seven health urban centers and one referral hospital. Findings showed that the mean age, height, fundal height, maternal weight, and gestational weight gain during pregnancy were 26.1 years, 159.1 cm, 32.9 cm, 72.0 kg, 11.8 kg respectively. The mean birth weight of neonates was 3.2 kg and 11% of neonates showed low birth weight. Age, family income, maternal height, weight, gestational weight gain and fundal height were significantly associated with birth weight of neonates. Using binary logistic regression analysis, fundal height, maternal hemoglobin, family income and gestational weight gain of pregnant women could be considered as predictive factors of birth weight of neonates.

Purpose: The aim of this study was to determine the predictive factors for maternal role development for mothers of premature infants. Methods: A descriptive correlational study was conducted. A total sample of 121 mothers of premature infants following discharge from the neonatal intensive care unit were recruited using two strategies; an internet-based survey and an in-person data collection in a tertiary university hospital in Korea. A self-report questionnaire was used to collect data regarding personal, birth variables, marital intimacy, maternal attachment, maternal identity and maternal role development. Results: A hierarchical multiple regression analysis indicated that parity, maternal attachment, marital intimacy and maternal identity were predictors for maternal role development for mothers of premature infants, accounting for 70% of the variance. Among these variables, maternal attachment is the most powerful predictor for maternal role development. Conclusion: Nursing interventions during hospitalization to post-discharge education that includes parents of premature babies with positive interaction between couples strengthening marital intimacy and promotes maternal attachment that leads to integrate maternal identity should be considered by priority. Community-based family services such as home visits should be focused on maximizing the predictive factors for maternal role development in transition to motherhood that can contribute to maternal health as well as optimal growth and development of premature infants.

It was assumed that the maternal identity in primi-gravida is one of the most attribute of the motherhood, that is not biological but cognitive phenomena, appears active process as intelligent human being. The purposes of this study were that the identification the cognitive structure and the influencing factors of the maternal identity in primi-gravida. Theoretical framework in this study, maternal identity in primi-gravida was constructed as a cognitive output, has the cognitive structure of cognitive-perceptual factor, cognitive-behavioral factor, and cognitive-emotional factor. Influencing factors of maternal identity was constructed as a cognitive input, which were pregnancy related perceptions (pregnancy intention, minor discomfort, value of motherhood), interpersonal relationship(relationship with mother, relationship with husband, relationship with social network), preparation to motherhood(maternal knowledge, antenatal self care), and biological factor (gestation period). This study was the descriptive correlational research design, was done from the 3rd January to the 15th March 1996, and the research subjects were selected conviniently 226 the primi-gravida during the gestation period, data collection method was self reported questionnaire cross-sectionally. Descriptive data analysis was done by SAS PC$^{+}$, testing the hypothetical model was done by covariance structural analysis using LISREL 8.03 program. The result of the hypothesis testing, the value of motherhood(y=.650, T=4.26) the maternal knowledge (y=.137, T=2.030), the gestation period( y=.113, T=2.621), showed significant causal effect on the maternal identity in primi-gravida. In conclusion, the maternal identity in primi-gravida had interrelated cognitive structure consist of perceptual, behavioral, and emotional factors. Significant causal factors influencing the maternal identity were value identified. It seems to contribute toward the understanding the characteristics of the maternal identity as a cognitive domains that has been regarded highly abstract concept, so has not been validated empirically.y.

This study was conducted to test the reliability and validity of Maternal Self-Report Inventory that was developed by Shea and Tronick for measuring maternal self-esteem. The subjects were 154 mothers. The construct validity for the scale was tested by factor analysis with five factor loading solution based on the previous study. One item was excluded because total-item correlation was too low, so that the number of total items were twenty-five, the analysis yielded five well defined factors: confidence on the maternal role, general ability of maternal role, caretaking ability, readiness on maternal role, and feeling on the pregnancy and deli very. These five factors explained 52.38% of the variance in the maternal self-esteem. Maternal self-esteem was not affected by maternal age, educational level, occupation, religion, delivery type, or parity. The reliability of the scale was determined with Cronbach's alpha coefficient and Guttman split-half coefficient. Cronbach's alpha was .82, for 26 items, and .83 if one item was deleted. Guttman split-half cofficient was .75. In subscale analysis, Cronbach's alpha was .63~.84. In conclusion. Maternal Self-Report Inventory showed a high degree of validity and reliability, suitable in Korean mothers for measuring maternal self-esteem. In the further study, it would be necessary to compare the maternal self-esteem between mothers with normal babies and premature babies, for confirming the criterion-related validity of the inventory.
