Purpose : A universal standard of the birth weight for gestational age cannot be made since girth weight distribution varies with race and other sociodemographic factors. This report aims to establish the birth weight distribution curve by gestational age, specific for Korean live births. Methods : We used the national birth certificate data of all live births in Korea from January 2001 to December 2003; for live births with gestational ages 24 weeks to 44 weeks(n=1,509,763), we obtained mean birth weigh, standard deviation and 10th, 25th, 50th, 75th and 90th percentile values for each gestational age group by one week increment. Then, we investigated the birth weight distribution of each gestational age group by the normal Gaussian model. To establish final standard values of Korean birth weight distribution by gestational age, we used the finite mixture model to eliminate erroneous birth slights for respective gestational ages. Results : For gestational ages 28 weeks 32 weeks, birth weight distribution showed a biologically implausible skewed tail or bimodal distribution. Following correction of the erroneous distribution by using the finite mixture model, the constructed curve of birth weight distribution was compared to those of other studies. The Korean birth weight percentile values were generally lower than those for Norwegians and North Americans, particularly after 37 weeks of gestation. The Korean curve was similar to that of Lubchenco both 50th and 90th percentiles, but generally the Korean curve had higher 10th percentile values. Conclusion : This birth weight distribution curve by gestational age is based on the most recent and the national population data compared to previous studies in Korea. We hope that for Korean infants, this curve will help clinicians in defining and managing the large for gestational age infants and also for infants with intrauterine growth retardation.

Purpose : The purpose of this study was to identify factors influencing premature infants who are small for their gestational ago. Methods : The medical records of 1,010 premature infants of 26 to 35 weeks of gestational age born at Il-Sin Christian Hospital, Busan from January 2000 to August 2006 were reviewed. We collected data on gestational age, birth weight, infant gender, birth order, maternal age and previous abortion history and analyzed the factors influencing premature infants who were small for their gestational ago at birth. Results : In our study more female than male (P=0.042) in premature infants who were small for their gestational ago were born from mothers aged younger than 20 or older than 35 (P=0.041). But association between smallness for gestational age and birth order or maternal previous abortion history was statistically insignificant (P=0.228, P=0.129). Conclusion : Considering the association of birth weight and the survival rate of premature infants, it is thought that maternal age had an influence on the survival rate of premature infants. Social and political support to lower the teenager pregnancy and older pregnancy is expected to increase the survival rate of premature infants and the birth of healthy normal neonates.

Serial ultrasonographic examinations were performed on 9 pregnant Korea Jin-do dog from days 15 to 60 to determine the size of gestational structures throughout pregnancy. Gestational age was timed from the day of ovulation (Day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0 ng/ml. Extra-fetal structures were measureable from days 17 to 49. Outer uterine diameter increased from $7.0{\pm}0.7$ ($mean{\pm}SD$)mm at day 17 to $54.0{\pm}2.2mm$ at day 49 and inner chorionic cavity diameter increased from $3.0{\pm}0.7mm$ at day 17 to $37.5{\pm}0.6mm$ at day 49. Uterine wall thickness increased from $2.8{\pm}0.4mm$ at day 17 to $8.3{\pm}0.5mm$ at day 49, placental thickness increased from $1.0{\pm}0.1mm$ at day 22 to $5.7{\pm}0.2mm$ at day 49 and length of chorionic cavity or zonary placenta increased from $5.5{\pm}1.3mm$ at day 20 to $52.3{\pm}2.2mm$ at day 49. Inner chorionic cavity diameter, outer uterine diameter and placental length each increased at a linear rate through day 37, after which time, each had a marked plateau in growth. Of the extra-fetal structures, inner chorionic cavity diameter was the most accurate for estimation of gestational age until day 37. Fetal structures were measureable from days l7 to 60. Crown-rump length, increased from $3.0{\pm}0.7mm$ at day 22 to $118.7{\pm}3.1mm$ at day 49, fetal body diameter increased from $4.0{\pm}0.7mm$ at day 25 to $55.8{\pm}1.7mm$ at day 60 and fetal head diameter increased from $4.3{\pm}0.6mm$ at day 26 to $29.8{\pm}0.8mm$ at day 60. Of the fetal structures, fetal head diameter was the most accurate for estimation of gestational age from day 37 until day 60.

Purpose: To examine the effects of a case management program on self-efficacy, depression and anxiety in pregnant women with gestational diabetes mellitus. Methods: Thirty-seven patients who enrolled in a diabetes outpatient clinic were randomly assigned to either an experimental group (n=19) or a control group (n=18). The experimental group received a 2-week intervention composed of a series of one face-to-face interactive interview and five telephone interviews based on the National standards for diabetes self-management education and Bandura's self-efficacy resources of performance accomplishment, vicarious experience, verbal persuasion, and emotional arousal. The effects of the intervention were assessed by completion of a 9-item self-efficacy questionnaire, a 20-item depression questionnaire and a 20-item anxiety questionnaire prior to, and after the intervention. The statistical significances were examined using t-test. Results: The change in self-efficacy was significantly greater in the experimental group than in the control group. Depression and anxiety changes in the experimental group were significantly greater compared to those in the control group. Conclusion: The results of study suggest that a case management program improves self-efficacy, and decreases depression and anxiety in pregnant women with gestational diabetes mellitus.

Purpose: We investigated behavioral problems, attention problems, and cognitive function in children and adolescents born small for gestational age (SGA). Methods: Forty-six SGA children born at term and 46 appropriate for gestational age (AGA) children born at term were compared. Psychiatric symptoms were examined with reference to the Korean-Child Behavior Checklist, Korean-Youth Self Report, and Attention Deficit Hyperactivity Disorder Rating Scale (ADHD-RS). Cognitive function was estimated using the Wechsler Intelligence Scale. Sociodemographic data were recorded from interviews. Results: SGA children had high scores on delinquent behavior, aggressive behavior, and the externalizing scale, and they also showed a propensity for anxiety and depression. The SGA group had a higher mean ADHD-RS score than the AGA group ($10.52{\pm}8.10$ vs.$9.93{\pm}7.23$), but the difference was not significant. The SGA group had a significantly lower verbal intelligence quotient (IQ) than the AGA group, but the mean scores of both groups were within normal limits. Conclusion: This study indicates marked behavioral problems, such as delinquency, aggressiveness, and anxiety and depression, as well as low verbal IQ in the SGA group than in the AGA group. Even in cases in which these symptoms are not severe, early detection and proper treatment can help these children adapt to society.

Purpose: This study aimed to summarize the current evidence on the effects of nonpharmacological interventions on psychological health outcomes for women with high-risk pregnancies due to conditions such as preeclampsia, gestational diabetes, or preterm labor. Methods: The following databases were searched from January 2000 to December 2020: PubMed, Ovid Embase, CINAHL, Web of Science, DBpia, RISS, and KISS. Two investigators independently reviewed and selected articles according to the inclusion/exclusion criteria. RoB 2 and the ROBINS-I checklist were used to evaluate study quality. Results: Twenty-nine studies with a combined total of 1,806 pregnant women were included in the systematic review and meta-analysis. Psychological health improvements were found in women with preeclampsia (Hedges' g=-0.67; 95% confidence interval [CI], -0.91 to -0.44), gestational diabetes (Hedges' g=-0.38; 95% CI, -0.54 to -0.12), and preterm labor (Hedges' g=-0.73; 95% CI, -1.00 to -0.46). The funnel plot was slightly asymmetrical, but the fail-safe N value and the trim-and-fill method showed no publication bias. Conclusion: Nonpharmacological interventions for women with high-risk pregnancies due to conditions such as preeclampsia, gestational diabetes, and preterm labor can improve psychological parameters such as anxiety, stress, and depression. Nurses can play a pivotal role in the nursing management of pregnant women with high-risk conditions and apply various types of nonpharmacological interventions to meet their needs in uncertain and anxious times during pregnancy.

The purpose of this study was to evaluate whether the MTHFR variants, folate and vitamin $B_{12}$ deficiencies increase the risk of hyperhomocysteinaemia and adverse pregnancy outcome such as short gestational age or reduced birth weight. Healthy pregnant women (n=136; 24-28 gestational weeks; 20-40 years old), who visited Ewha Womans University Hospital for prenatal care, participated in this study. At the time of delivery, trained nurses recorded the pregnancy outcome from medical chart. We determined maternal MTHFR polymorphisms (C to T subsitution at nucleotide 677) and measured serum homocyteine, vitamin $B_{12}$, and folate concentrations. We compared serum homocysteine level by MTHFR genotype, serum folate and serum vitamin B12 levels using ANOVA. To evaluate the association between serum homocysteine level and pregnancy outcome, we compared the gestational age and birth weight by serum homocysteine levels using multiple regression analysis, adjusting for other potential predictors. Mean level of serum homocysteine was highest among pregnant women of the MTHFR variants with low levels of serum folate and vitamin $B_{12}$. Regarding association with birth outcome, we found the relationship between homocysteine levels and increased gestational age (p=0.03) and reduced birth outcome (p>0.05). Our data demonstrates that serum level of folate and vitamin $B_{12}$ among pregnant women affects significantly serum homocysteine levels, and the genetic polymorphism of MTHFR modulates the relationship between them. However, we did not have conclusive evidence of association between high homocysteine level and adverse pregnancy outcome such as preterm or low birth weight.

Background: Gestational trophoblastic neoplasia (GTN) is a malignant disease which occurs in women of reproductive age. Treatment of GTN has an excellent outcome and further pregnancies can be expected. However, data concerning quality of life in these cancer survivor patients are limited. This study aimed to assess quality of life in women who were diagnosed with GTN and remission after treatment, and to determine factors that may affect quality of life status. Materials and Methods: This cross sectional study was conducted from July 2013 to May 2014 in the Gestational Trophoblastic Disease Clinic, King Chulalongkorn Memorial Hospital, Bangkok, Thailand. Patients who were diagnosed GTN and complete remission were recruited. Data collection was accomplished by interview with two sets of questionnaires, one general covering demographic data and the other focusing on quality of life, the fourth version of Functional Assessment of Cancer Therapy (FACT-G). Descriptive statistics were used to determine general data and quality of life scores. Students t-test and one way ANOVA were used to compare between categorical and continuous data. Results: Forty four patients were enrolled in this study. The overall mean quality of life score (FACT-G) was 98.2. The overall FACT-G score was not significantly correlated with age, education level, stage of disease, treatment modalities, and time interval from remission to enrollment. However, patients who needed further fertility showed significant lower FACT-G scores in the emotional well-being domain (p=0.02). Conclusions: Overall quality of life scores in post-treatment gestational trophoblastic neoplasia patients are in the mild impairment range. Patients who desire fertility suffer lower quality of life in the emotional well-being domain.
