97-OR: Randomization to a Higher–Complex Carbohydrate vs. Conventional Diet in GDM Improves Glucose Tolerance and Results in Similar Cord Blood Insulin and Newborn Adiposity
Robust evidence for specific nutrition therapy for gestational diabetes (GDM) is lacking. Preliminary data suggested our CHOICE diet, higher in complex carbohydrate (60%) and lower in fat (25%) reduced fasting glucose (FBG), free fatty acids (FFA), and newborn adiposity (NB%fat). We tested the hypot...

description | Robust evidence for specific nutrition therapy for gestational diabetes (GDM) is lacking. Preliminary data suggested our CHOICE diet, higher in complex carbohydrate (60%) and lower in fat (25%) reduced fasting glucose (FBG), free fatty acids (FFA), and newborn adiposity (NB%fat). We tested the hypothesis that 7-8 wks of CHOICE would improve insulin resistance, reduce FFA and NB%fat (2-wk PeaPod; 1° powered outcome) vs. a conventional low-carbohydrate (40%), higher fat (45%) diet (LC/CONV). After diagnosis (∼28-30 wks), 59 BMI-matched diet-controlled GDM women (mean±SD; BMI 32±5) were randomized to a eucaloric CHOICE or LC/CONV diet (7.2±1 wks; ALL MEALS PROVIDED). At baseline, a 2-hr 75g OGTT (with insulins) was performed and diet initiated. On day-4, a breakfast meal was given (30% of total calories) with fasting and hourly blood drawn x5 (gluc, insulin, FFA, triglycerides[TG]) for area-under-the curve (AUC). Measures were repeated at 36-37 wks. Of 59, 13 met exclusions (4 diet failures, 2/group). By ANCOVA (n=23/group), total and weight gain during diet were similar (CHOICE 1.9 vs. LC/CONV 1.8 kg) as was delivery wk (39.2 vs. 39.3 wks). At 37 wks, the meal gluc (p=0.001) and insulin AUCs (p=0.013) were lower for LC/CONV, though fasting gluc/insulin were similar. TG increased similarly. The FFA AUC decreased from 30-37 wks on CHOICE but rose on LC/CONV (p=0.016), and was lower for CHOICE at 37 wks (p=0.009). By the 37-wk OGTT, FBG decreased within both groups (CHOICE -7.2, LC/CONV -3.5 mg/dL, both p |
