ABSTRACT
<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>

<p><b>OBJECTIVE</b>To investigate effects of medium- and long-chain fatty acid triacylglycerols (MLCT) on body fat and serum lipid in overweight and hypertriglyceridemic subjects.</p><p><b>METHODS</b>A double-blind, controlled clinical trial was carried out, in which 112 subjects with hypertriglyceridemia were enrolled and divided into two groups, there were 56 subjects in each group. One group was randomized to consume long-chain fatty acid triacylglycerol (LCT), and the other to MLCT. All volunteers were asked to consume 25 - 30 g test oil daily for consecutive 8 weeks. Anthropometric measurements of body weight, body fat weight, waist circumference(WC), hip circumference(HC), WHR (ratio of WC/HC), total fat weight, subcutaneous fat area, visceral fat area, and serum biochemical variables of glucose, total cholesterols(TC), triglycerides(TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C)were measured at the initial and final time of the study.</p><p><b>RESULTS</b>11 subjects were excluded from the study because of various reasons. Of the 101 included cases, there were 50 (male subject 34, 68.0%) and 51 (male subject 33, 64.7%) subjects left in LCT and MLCT group respectively. The proportion of men in MLCT (64.7%, 33/51) was not significantly different (chi(2) = 0.1227, P > 0.05) compared to those in LCT (68.0%, 34/50). The average age of MLCT was (54.2 +/- 12.5) which was not significantly different (t = 0.39, P > 0.05) compared to those in LCT (53.2 +/- 13.0); Body mass index (BMI) of MLCT was (25.9 +/- 3.3) kg/m(2), which was not significantly different (t = 0.08, P > 0.05) compared to those of LCT (25.9 +/- 2.4) kg/m(2). After consumption of test oil for 8 weeks, extent of decrease in BMI, percent of body fat, subcutaneous fat, serum TG and serum LDL-C in overweight subjects of MLCT were (-0.73 +/- 0.61) kg/m(2), (-1.53 +/- 1.32)%, (-16.29 +/- 19.25) cm(2), (-0.57 +/- 0.86) mmol/L and (-0.05 +/- 0.64) mmol/L respectively, those in overweight subjects of LCT were (-0.19 +/- 0.61) kg/m(2), (-0.58 +/- 1.02)%, (4.69 +/- 19.06) cm(2), (0.65 +/- 1.10) mmol/L and (0.38 +/- 0.58) mmol/L respectively, all of them were significantly different (the value of t were -2.70, -2.43, -3.20, -3.81 and -2.09 respectively, all of P value were less than 0.05).</p><p><b>CONCLUSION</b>Consumption of MLCT can reduce body fat weight and serum triacylglycerol and LDL-C in overweight hypertriglyceridemic subjects under an appropriate dietary regime.</p>
