Obecity in pregnancy causes many problems and increases risk of pregnancy complications at the time of childbirth. But there is a lack of comprehensive analysis of factors that are negatively affected during pregnancy. Therefore, this study is intended to analyze seven factors of high-risk maternal diseases by the degree of obesity using body mass index(BMI). We conducted a cross tabulation analysis and regression analysis to analisized relationship between variables : Gestational Hypertension(GH), Gestational Diabetes Mellitus(GDM), Thyroid Stimulation Hormone(TSH), Age, Blood Urea Nitrogen Test(BUN), Total-Cholesterol(T-C), and newborn's weight. As a result, the more the obesity level of mothers increases, the more the proportion of mothers with GH, GDM, TSH increases. And there was a positive relationship between the BMI of mothers and their age, T-C, and Newborn weight, and a negative relationship to the BUN.

Purpose:This study compares the maternal characteristics and birth outcomes of infants of Asian immigrant mothers from developing countries with those of the infants of Korean mothers. Methods:In this multicenter and retrospective study, Asian immigrant women who had delivered between January 2005 and June 2008 were enrolled from9 Medical Centers. In all, 333 births to Asian immigrant women from developing countries (Asian-Korean infants) were included in this study. In addition, sex-, birth year-, and gestational age-matched 333 neonates born to Korean mothers were selected as the control group (Korean infants). On the basis of the hospital data, we investigated the nationality, age, and medical history of the mothers and compared the incidence of congenital infection, Apgar score, weight, height, and head circumference of Asian-Korean infants with those of the Korean infants. Results:The average maternal age of Asian women from developing countries at birth term was 26.7 years, which was significantly lower than that of Korean women (30.8 years, P<0.05). The birth weight of Asian-Korean infants (2,869 g) was significantly smaller than that of Korean infants (2,995 g, P<0.05). There was a significant difference in the incidence of congenital syphilis infection between the Asian-Korean infants and Korean infants (5 cases vs. 0 case, P<0.05). Conclusion:There were significant differences in the perinatal outcomes between the Korean and Asian-Korean infants. A multicenter large-scaled study should be performed to analyze the perinatal outcomes of Asian-Korean infants.

To study the risk factors associated with maternal HBsAg carrier and the effects of maternal HBs antigenemia on the neonatal health, sera of 729 pergnant women admitted to the Keimyung University Hospital for delivery during the period of February 1-May 30. 1982 were tested for HBsAg by RPHA method and for anti-HBs by PHA method. Among them 43 women (5.9%) had HBsAg and 246 women (33.7%) had anti-HBs giving an infection rate of 39.6%. The interview data for 43 HBsAg positive mothers and randomly selected 210 HBsAg negative mothers showed a statistically significant association between acupuncture history and HBsAg positive rate (p<0.005) which suggest that acupuncture might have contributed significantly to the propagation of viral hepatitis in Korea. The living standard of HBsAg positive mothers was generally lower than that of HBsAg negative mothers which supports the hypothesis that environmental factors are associated with viral hepatitis B infection. None of the 43 neonates born to HBsAg positive mothers had HBsAg in their cord blood. Three months after birth, 35 out of 43 infants were retested and only one infant became HBsAg positive. At six months of age, 32 out of 35 infants were retested and none of them were HBsAg positive except the same infant who was positive at three months. Among 20 control infants of HBsAg negative mothers, all of them were HBsAg negative at three and six months follow-up. These findings are not consistent with the supposition that perinatal infection is a main route of viral hepatitis B transmission in south-east Asia including Korea. HBsAg positive mothers had significantly higher rate of premature delivery (27.9%) than HBsAg negative mothers (11.7%) (p<0.05). Also, the low birthweight incidence rate was higher among HBsAg positive mothers (23.3%) than negative mothers (14.1%) but this was not statistically significant (P=0.16). The premature rupture of membrane was more frequent among HBsAg positive mothers (25.5%) than negative mothers (11.1%) (p<0.05). There were no significant differences in the stillbirth rate and incidence of congenital anomalies between HBsAg positive and negative groups. It was not clarified in this study due to small sample size whether higher incidence of premature delivery and premature rupture of membranes among HBsAg positive mothers was due to HBs antigenemia per so or their lower living standard than HBsAg negative mothers.

Purposes : This study was performed to evaluate the seropositivities and levels of term pregnant women and their neonates, and the transplacental transfer rate of maternal Epstein-Barr Virus-specific IgG(VCA IgG and EBNA IgG) from term pregnant women to their neonates. Subjects and Methods : During Jan. 1, 1997 to Mar. 31. 1997, we collected the 42 pairs of sera from pregnant women and umbilical cord of their neonates in Korea University Ansan Hospital. The serum levels of VCA IgG and EBNA IgG were measured by the ELISA method. Results : 1) The seropositivities of VCA IgG were 100% in mothers and neonates. There was no statistical difference of mean VCA IgG levels between mothers and neonates. There was significant correlation of VCA IgG levels between maternal sera and neonatal umbilical cord sera(correlation coefficient r=0.5214, P<0.001). 2) The seropositivities of EBNA IgG were 100% in mothers and neonates. There was no significant difference of the mean EBNA IgG levels between mothers and neonates. There was significant correlation of EBNA IgG levels between maternal sera and neonatal umbilical cord sera (correlation coefficient r=0.7244, P<0.001). 3) There was no correlation between VCA IgG and EBNA IgG levels of maternal sera. Conclusion : Seropositivities of EBV CA IgG and EBNA IgG of term-pregnant women and their neonates were 100% and no significant differences of antibody levels were found in two groups. It seems that EBV Antibody levels in Korean mothers and neonates were high enough to protect primary EBV infection during early infancy.

The purpose of this study was to examine the relationship between maternal age and infant mortality in Korea(n=617,867). Data of Korean vital statistics linked National Infant Mortality Survey conducted on births in 1999 were used in this study. The odds ratios (ORs) of infant death by maternal age were estimated with the multiple logistic regression model, adjusting for gender, plurality, birth order, low birth weight, and congenital malformation. After adjusting for the relevant variables, the odds of infant death in the group of maternal age with less than 20 years(Odds ratio [OR], 5.29, 95% confidence interval [CI], 3.51-7.98), 20-24 years(OR, 1.44, 95% CI, 1.23-1.69), 35-39 years(OR, 1.28, 95% CI, 1.11-1.46), and more than 40 years(OR, 1.94, 95% CI, 1.53-2.45) was higher than that of reference group(25-29 years). In conclusion, the higher infant mortality in the group of maternal age with less than 25 years and more than 35 years in Korea appears to be due to higher proportion of low birth weight and pre-term birth. Prenatal care intervention programs which tackle biological factors for advanced maternal age and address socio-economic problems and social stigma for early maternal age should be devised.

This study was conducted to compare the maternal charactristics, and birth weight of infants delivered at five different categories of medical facility in Taegu to examine the risk level of pregnant women and children by the medical facility for delivery. The study population included 1,410 pregnant women who delivered a baby at one of nine medical facilities (3 university hospitals, 2 general hospitals, 2 private clinics, 1 midwife clinic, 1 MCH center) in Taegu in April, 1987(April and May, 1987 for K university hospital), Pregnant women were interviewed to ask the age and educational level of woman, payment of medical fee, birth order, delivery method. Birth weight of infant was obtained from medical record. Mean ages of the women delivering at the university hospitals(27.5 years) and at general hospitals(26.7 years) were higher than those at midwife clinic(25.4 years) and at MCH center(26.1 years). Also, mean years of school education were higher in women of university hospitals(12.7 years) and general hospitals (12.2 years) than in women of midwife clinic(9.2 years) and MCH center (9.3 years). The percentages of women covered by the medical insurance were far greater in the university hospitals(78.1%) and general hospitals(82.9%) than in private clinics(44.3%) , midwife clinic(29.1%) and MCH center (5.4%). Infants born at the MCH center were mostly the second birth (47.3%) while 56.0% to 61.7% of infants born at all the other medical facilities were the first birth more women delivering at the university hospitals had history of spontaneous abortion as well as still birth than the women delivering at the other medical facilities. The preform birth rate (11.4%) and low birthweight incidence rates(5.8-13.0%) in university hospitals were significantly higher than those of other medical facilities. Accordingly, c-section rates showed a wide variation among the medical facilities. Study findings revealed that most of women delivering at the university hospitals and general hospitals are in the middle of or upper socio-economic class and obstetrically high risk group regardless of socioeconomic class while the wome delivering at the midwife clinic and MCH center are low risk group of low socioeconomic class. Therefore, the data of a specific medical facility are highly limited in interpretation and can not be generalized.

This study was carried out to evaluate the minerals and trace elements contents in colostrum milk produced from 30 normal healthy mothers delivery at term, 10 mothers delivery preterm and 8 pregnancy induced hypertensive mothers(PIH) and to investigate the relationship between maternal minerals intakes during pregnancy and milk contents of minerals. Five minerals(Na, K, Ca, P, Mg) and three trace elements(Fe, Zn, Cu) in colostrum were determined by ICP-AES and maternal dietary intakes during pregnancy were estimated by semiquantitative frequency questionnaire. Maternal dietary intakes of three groups during pregnancy were below the recommended allowances except protein and phosphorus. The overall mean nutrients intakes of mothers delivered preterm were the lowest among three study groups, especially phosphorus and sodium intakes of preterm mothers were significantly lower than those of normal term mothers(p < 0.05). Dietary intakes of mothers with pregnancy induced hypertension were similar to those of normal term mothers except calcium intake of pregnancy induced hypefensive mother was the lowest among three groups. While potassium and phosphorus concentrations in preterm colosalm were significantly lower than those of term milk(p < 0.05), iron contents of colostrum in preterm and PIH groups were significantly higher than term milk respectively(p < 0.07). The other minerals concentrations of colostrum produced by the preterm mothers tended to be lower than term milk. There were not significant relationships between maternal dietary intakes of minerals during pregnancy and the corresponding mineral levels of colostrum of three groups of mothers except that Pearson correlation coefficient showed positive significant relationships between the calcium intakes of PIH mothers and the colostrum milk calcium levels. These results suggest that preterm milk might be insufficient for the mineral nutrition of preterm infects in considering of the poor tissue storage of minerals and catch-up growth of preterm infects.

Purpose : This study was performed to evaluate the seropositivities and levels of Hepatitis A Virus(Hav) antibody in term pregnant women and their neonates, and the transplacental transfer rate of maternal Hav-specific IgG(Hav IgG) from tenn pregnant women to their neonates. Methods : During Jan. 1st, 1998 to May. 31 tho 1998, we collected the 42 pairs of sera from pregnant women and umbilical cord of their neonates in Korea University Ansan Hospital. The serum levels of Hav IgG were measured by the RIA method. Results : 1) The seropositivities of Hav IgG were 78.6% in mothers and 81.0% in neonates. There was no statistical difference of mean antibody(Ab) levels between mothers and neonates. There was significant correlation of Ab levels between maternal sera and neonatal umbilical cord sera(correlation coefficient r=0.9285, P<0.001). 2) There were no significant correlations between neonatal Hav IgG level and other factors such as maternal age, gestational age and initial body weight of neonates. Conclusion : Seropositivities of Hav IgG tenn-pregnant women was comparable to those of their neonates. Pregnant women and their neonates can be protected from Hav infection.

To investigate the blood lead concentration, their interrelation, correlation factor and influence on pregnant women and newborn, lead concentration in the maternal blood and umbilical cord blood were determined. Samples were collected from 130 mothers who were living in the Taegu City, during March, 1989. Blood lead concentration was estimated using the Atomic Absorption Spectrophotometer(IL. 551) equipped with Flameless Furnace Atomizer (IL. 665). The mean lead concentration of maternal and cord blood were $17.47{\pm}7.92{\mu}g/d{\ell}$, $15.31{\pm}7.98{\mu}g/d{\ell}$, respectively. A significant correlation was observed between the lead concentration of maternal and cord blood, r=0.663, Y=0.667X+3.646. No significant correlation was observed between previous spontaneous abortion and obstetric complication of mother and maternal blood lead concentration. Similarly, no significant correlation was observed between the sex, gestational age of neonate and cord blood lead concentration. But the birth weight of neonate had some negative correlation with cord blood lead concentration. The blood lead concentration of mother who had engaged in manufactures were higher than others and the longer working years were, the higher blood lead concentration were. Significant correlation was observed between husband's occupational exposure to lead and maternal blood lead concentration.
