ABSTRACT
Objective To analyze the association between pre-pregnancy body mass index,pregnancy weight gain and gestational diabetes(GDM).Methods The pre-pregnancy body mass index,pregnancy weight gain and the incidence data of 345 gestational diabetes with full-term primiparae were analyzed.Results The GDM ratio of low-weight,ideal weight group,over-weight was 2.78％,2.96％,16.04％,respectively over-weight GDM pregnancy was significantly higher than the ideal weight group( x2 =4.269,P ＜0.05),and GDM over-weight before pregnancy was significantly higher than the low weight group the incidence of GDM,the difference was statistically significant( x2 =17.299,P ＜0.01 ) ;Pregnant women in different pregnancy weight gain A( ＜ 11.0kg),B( 11.0 ～ 17.9kg),C( 18.0～24.9kg),D(≥25.0kg) range,the GDM were 0％,1.75％,6.60％,11.02％,that GDM of A,B,C,D group were statistically different( P ＜ 0.05 ).Rate of weight gain during pregnancy on pregnancy size was proportional to the impact of diabetes.Conclusion Pre-pregnancy body mass index,pregnancy weight gain had clinical significance in evaluation of gestational diabetes.
ABSTRACT
OBJECTIVE: To establish the biweekly standard values of pregnancy weight gains for primiparas and multiparas, and to investigate the influence of prepregnancy body mass index on biweekly weight gain during pregnancy. METHODS: We analyzed the biweekly weight gain data from 536 primiparas and 114 multiparas who had noncomplicated singleton term pregnancy. Data was categorized according to parity and body mass index (BMI). RESULTS: Biweekly weight gain was significantly different among prepregnancy BMI groups from the 15th week but was not different between primiparas and multiparas. CONCLUSION: To prevent a lot of complications which may be associated with abnormal weight gain during pregnancy, more careful prenatal care according to the prepregnancy BMI groups is needed. To establish the Korean standard value for antenatal weight gain, a nationwide multicenter study is needed.

The necessity of adequate pregnancy weight gain for optimal pregnancy outcome has been recognized. However, the specific components of pregnancy weight gain that might be critical for fetal growth and development have not been elucidated clearly. The purpose of this study was to investigate the correlation of pregnancy weight gain and birth weight with serum leptin levels in women delivered newborns. The subjects were recruited from K university hospital. The subject's characteristic data (age 32.1+/-4.3 y, gestational age 39.5+/-1.1wk, pre-pregnancy weight 58.0+/-8.6 kg, pregnancy weight gain 12.7+/-5.5 kg, newborn's birth weight 3.5+/-0.5 kg) were gathered. Maternal dietary assessment was carried out at the end of pregnancy. After delivery, blood samples were collected from 20 mother-newborn pairs. Serum levels of various lipids and leptin were analyzed. Maternal daily consumption of iron, zinc, folate were lower than the RDA of each nutrient and index of nutritional quality was less than 1 showing that the quality of maternal diet was low. The levels of serum leptin of mothers and infants were 10.2+/-6.7 ng/ ml and 1.7+/-0.6 ng/ml, respectively. The serum leptin concentrations of male infants (1.9+/-0.7 ng /ml) were not different from that of females (1.7+/-0.5 ng/ml). A negative correlation was found between the maternal pre-pregnant BMI and weight gain during pregnancy (r=-0.54, p<0.05). There was a positive correlation between the pregnancy weight gain and the newborn's birth weight (r = 0.59, p<0.01). There were also positive correlation between newborn's birth weight and newborn's serum leptin levels (r =0.57, p<0.01). No correlations were found between maternal serum leptin levels and that of newborn's. Efforts should be made to attain adequate diet and weight gain during the pregnancy to reduce the likelihood of low or over birth weight of newborns.

OBJECTIVE: To calculate monthly weight gains during pregnancy among 20s, early and late 30s, and to investigate the influence of age groups on monthly weight gains. METHODS: We analyzed the monthly weight gain data from 892 women who had visited before 20 weeks of gestation and had healthy singleton term pregnancy. Data was categorized in three groups according to age (20s, early and late 30s). RESULTS: The monthly weight gain tables among 20s, early and late 30s have been determined. Monthly weight gain was not significantly different among three age groups. CONCLUSION: Although statistically insignificant among three age groups, more cautious prenatal care according to the monthly weight gain-gestational month tables for each age group is needed to prevent complications which may be associated with abnormal weight gain during pregnancy.

OBJECTIVE: To establish the standard values for proper antenatal weight gain, biweekly mean weight gains, standard deviations were calculated from the 5th to the 42nd gestational week and their percentiles were determined. And the influence of prepregnancy body mass index and/or parity on biweekly weight gain was investigated. METHODS: We analyzed the biweekly weight gain data from 910 women who had noncomplicated singleton term pregnancy. Data was categorized in three groups according to body mass index (BMI). RESULTS: The biweekly weight gain table has been determined and 'Sigmoid(S) shaped' weight gain curves were presented. Primipara and multipara have significantly less weight gain than nullipara beyond the 25th weeks. Biweekly weight gain was significantly different among prepregnancy BMI groups from the 13th week. CONCLUSION: More careful prenatal care according to the biweekly weight gain-gestational week tables is needed to prevent a lot of complications which may be associated with abnormal weight gain during pregnancy. To establish Korean standard value for antenatal weight gain, a nationwide multicenter study is needed.

OBJECTIVE: Mean weight gains, standard deviations were calculated for each gestational months and the 10th, 25th, 50th, 75th, and 90th percentiles were determined. And the influence of prepregnancy body mass index and/or parity on monthly weight gain was investigated. METHODS: We analyzed the monthly weight gain data from 876 women who had healthy sigleton term pregnancy in Han-il Hospital(Jul 2001-Jun 2002). Data were categorized in three groups according to the prepregnancy body mass index. RESULTS: The monthly weight gain table has been determined and 'Sigmoid(S) shaped' monthly weight gain curve was presented. Primipara and multipara have less weight gain than nullipara in the 5th and the 7th-11th months. Monthly weight gains adjusted for parity and age were significantly different among prepregnancy body mass index groups from the 4th month. CONCLUSIONS: More careful prenatal care according to the monthly weight gain-gestational month tables is needed to prevent a lot of complications which may be associated with abnormal weight gain during pregnancy.
