<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>
