The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus (GDM).</p><p><b>METHODS</b>A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation (WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity.</p><p><b>RESULTS</b>Age, pre-pregnant body weight (BW), and body mass index (BMI) were associated with increased risk of GDM. Fat mass (FM), fat mass percentage (FMP), extracellular water (ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass (FFM), muscular mass (MM), and intracellular water (ICW) were associated with a decreased risk of GDM.</p><p><b>CONCLUSION</b>Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity.</p>

Evaluation of the glucose screening retest during pregnancy / 中华妇产科杂志

Objective To evaluate of the glucose screening retest for gestational diabetes mellitus (GDM) during pregnancy. Methods A retrospective analysis of 714 pregnant women screened for GDM, between December 1,2001, and December 31,2002, was performed.The first glucose challenge test(GCT) was performed in 16～27 week and retested in 28～38 week.Diagnosis of GDM was based on the criteria of Dong.NDDG criteria was also discussed. Results (1) 1-hour glucose value of 50 g GCT ≥7.8 mmol/L was set as abnormal.The first 50 g GCT abnormal rate was 26.6%(190/714),and the retest abnormal rate was 35.2%(225/639).The mean age of pregnant women in 50 g GCT positive group was significantly higher than that in the negative group( P
