Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM).Methods 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 GDIVl morbidity.Results 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.Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity. 展开更多

LiNbO_(3)的非线性光学系数d_(33)比KDP的d_(36)大60~70倍,虽然d_(33)不能位相匹配,但我们已经实现了d_(33)的准位相匹配,证明了通过准位相匹配的聚片多畴LiNbO_(3)晶体是获得高效倍频转换的有效途径。因而LiNbO_(3)是作为激光二极管倍... LiNbO_(3)的非线性光学系数d_(33)比KDP的d_(36)大60~70倍,虽然d_(33)不能位相匹配,但我们已经实现了d_(33)的准位相匹配,证明了通过准位相匹配的聚片多畴LiNbO_(3)晶体是获得高效倍频转换的有效途径。因而LiNbO_(3)是作为激光二极管倍频的理想倍频晶体。 展开更多
