  • This study was conducted to determine which variables of interest could be used to predict the development of infants. The variables of interest in this study were demographic variables regarding to the infants and mothers, maternal knowledge of infant development, maternal self-efficacy, maternal parenting stress, and infant development. The participants consisted of 252 infant-mother pairs and all infants included in this study were 15 months to 36 months of age. The development of Infants was assessed by classroom teachers. Data regarding the mothers’' demographic information, maternal knowledge of infant development, maternal self-efficacy, and maternal stress were gathered by maternal self-reported questionnaires. Data were analyzed by descriptive statistics, t tests, and regression analyses. The primary results demonstrated that family income, maternal infant knowledge, and maternal parenting stress were predictive of the infant development. In addition, different patterns in the results of the stepwise multiple regression were observed among the infant’'s of different age. Implications for research and practice were discussed along with the results of study.

  • The purpose of this study is to compare life stress between primigravida and multigravida in advanced maternal age. A cross-sectional study was performed for 133 pregnancy women (primigravida group 53, multigravida group 80). The all women were old age (${\geq}35years$) and pregnant. We used the questionnaire to self-report general characteristics, obstetric characteristics and life stress. The average of participants age was 36.15 years old, primigravida was 36.08 and multigravida was 36.19. The mean of total life stress score was 2.68 and the total life score for pregnant women of lower education level was higher. The marital relationship of primigravida was lower than multigravida(mean, .06 vs. .26; p=.021). As our study shows that stress of marital relationship is higher in the multigravida than primigravida, the life stress care for advanced maternal age is important.

  • The purpose of this research is to delineate the effect of maternal variables of the verbal abuse. Such variables as the mother's age, her education level, and maternal parenting stress have been chosen for the analysis. The sample subject were 659 pairs of fifth/sixth grade of elementary school and firs/second grade of middle school, and their mothers. The major findings of the research are as follows: first, looking at the correlation between the mother's age/education level and the verbal abuse, the verbal abuse factor shows difference correlating to the mother's age/education level. Second, looking at the correlation between the material parenting stress level and the verbal abuse, the verbal abuse factor shows difference correlating to the maternal parenting stress level. Third, the result of multiple regression analysis on the effects of the maternal variables to the verbal abuse indicates that material parenting stress is the significant contributing factor. All in all, the maternal variables account for 9% of the verbal abuse score.

  • This study examined the influences on maternal acceptance-rejection and mediating effects of parenting stress. Participants were 150 mothers of children aged 3 to 6 in Seoul and Jeju. Research questions were analyzed by structural equation modeling. Results showed that children's age, congenital diseases or anomalies, planned pregnancy, and father's occupation influenced maternal acceptance-rejection directly. Mothers' perceived treatment in childhood and fathers' age influenced parenting stress; parenting stress, in turn, influenced maternal acceptance-rejection. Fathers' age influenced parenting stress negatively; parenting stress, in turn, influenced maternal acceptance-rejection positively.

  • Objective: It is widely accepted that aging decreases women's fertility capacity. The aim of this study was to assess correlations between maternal age and the morphokinetic parameters and cleavage pattern of embryos. Methods: The morphokinetics of embryos derived from women < 30, 30-35, 36-40, and > 40 years of age were compared retrospectively in terms of time of second polar body extrusion, time of pronuclei appearance, time of pronuclei fading, and time of two to eight discrete cells (t2-t8). Furthermore, abnormal cleavage patterns such as uneven blastomeres at the two-cell stage, cell fusion (Fu), and trichotomous mitoses (TM) were assessed. Results: Only t5 occurred later in women aged 36-40 and > 40 years when compared with those aged < 30 and 30-35 years (p< 0.001). Other morphokinetic timing parameters, as well the presence of uneven blastomeres, were comparable between the groups (p> 0.05). However, Fu and TM were more common in women aged > 40 years than in younger women (p< 0.001). Conclusion: Maternal age was correlated with the cleavage pattern of embryos. Therefore, evaluating embryo morphokinetics may contribute to optimal embryo selection, thereby increasing fertility in patients with advanced maternal age.

  • This study examined the longitudinal effects of media usage by early school-age children and of maternal parenting stress on children's school adjustment. The study focused on the mediating effect of executive function difficulty. Longitudinal data to examine the hypothetical model were drawn from the eighth (2015) through tenth (2017) waves of the Panel Study of Korean Children (PSKC) collected by the Korea Institute of Child Care and Education (KICCE). A total of 581 children (293 boys and 288 girls) and their mothers were included. Confirmatory factor analysis, structural equation model, and bootstrapping analysis were applied using SPSS 25.0 and Amos 26.0. The results are as follows. First, no significant correlation was found between early school-age children's media usage and maternal parenting stress. Second, neither media usage by early school-age children nor maternal parenting stress were found to directly affect children's school adjustment. Third, media usage by early school-age children and maternal parenting stress were shown to indirectly affect children's school adjustment via executive function difficulties. In other words, higher levels of media usage by early school-age children and maternal parenting stress during the first grade lead to greater executive function difficulties after a year, which, in turn, lead to a lower level of school adjustment in the third grade. This study indicates the need to develop practical support for the psychological wellbeing of mothers while they are performing their role as a parent and for children in maintaining suitable levels of media usage during early childhood.

  • A sample of 322 18-month-old infants and their mothers were assessed longitudinally at 24 and 30 months. Maternal utterances and styles of linguistic interaction were measured during a 10 minute free play session. Mothers completed a vocabulary checklist for infants. Longitudinal data were analyzed by multilevel modeling. Results indicated that vocabulary increased with age of infants and the growth rate was highly predictable by the size of vocabulary at 18 months. The growth rate was strongly influenced by maternal questioning and feedback. The effect of the maternal linguistic input was constant with age. Gender differences in size of vocabulary did not vary systematically with age.

  • Objectives: This study measured the impact of shifts in maternal age and parity on the increase in the low birth weight (LBW) rate in Korea. Methods: We obtained raw data for all 6 397 945 live births registered at the Korea National Statistical Office between 1995 and 2005. We calculated the proportion of increment in the LBW rate due to changes in the distribution of maternal age and parity (AP-dis) and the proportion due to changes in the age- and parity-specific LBW rate (AP-spe). Results: The LBW rate increased from 3.02% in 1995 to 4.28% in 2005. The multiple birth rate increased from 1.32% to 2.19% during the same period. Of the 1.26% points increment in the LBW rate, 0.64% points occurred among singleton births and 0.62% points occurred among multiple births. Changes in the AP-dis accounted for 50% of the increase in the LBW rate among singleton births, but did not contribute to the increase in the LBW rate among multiple births. The remainder of the total increment in the LBW rate was explained by the increase in the AP-spe. Conclusions: This study demonstrated that shifts in maternal age and parity among singleton births and increased multiple births were important contributors to the increment in the LBW rate. This study also revealed that the increase in the AP-spe was an equally important contributor as the shifts in maternal age and parity to the increment in the LBW rate among singleton births and was a major contributor among multiple births.

  • Purpose: This study aimed to identify maternal, infant, and perinatal mortality using the national population data of South Korea between 2018 and 2020, and to analyze mortality rates according to characteristics such as age, date of death, and cause of death in each group. This study updates the most recent study using 2009 to 2017 data. Methods: Analyses of maternal, infant, and perinatal mortality were done with data identified through the supplementary investigation system for cases of death from the Census of Population Dynamics data provided by Statistics Korea from 2018 to 2020. Results: Between 2018 and 2020, a total of 99 maternal deaths, 2,427 infant deaths, and 2,408 perinatal deaths were identified from 901,835 live births. The maternal mortality ratio was 11.3 deaths per 100,000 live births in 2018; it decreased to 9.9 in 2019 but increased again to 11.8 in 2020. The maternal mortality ratio increased steeply in women over the age of 40 years. An increasing trend in the maternal mortality ratio was found for complications related to the puerperium and hypertensive disorders. Both infant and perinatal mortality continued to decrease, from 2.8 deaths per 1,000 live births in 2018 to 2.5 in 2020 and from 2.8 in 2018 to 2.5 in 2020, respectively. Conclusion: Overall, the maternal, infant, and perinatal mortality statistics showed improvements. However, more attention should be paid to women over 40 years of age and specific causes of maternal deaths, which should be taken into account in Korea's maternal and child health policies.
