Adverse Pregnancy Outcomes, Fasting Plasma Glucose, Gestational Diabetes Mellitus, Gestational Weight Gain, HbA1c, Medical Nutrition Therapy
Conditions
Brief summary
Background: Gestational diabetes mellitus (GDM), GDM is the first time of gestational impaired glucose tolerance in pregnant women. It is the most common complication disease in women of childbearing age. It is associated with the high risk of adverse health outcomes for both mothers and offsprings and the variety of metabolic disease, including type 2 diabetes, etc. As for the epidemiology data of GDM in China, the prevalence is around 18% based on the criteria from the International Association of Diabetes in Pregnancy Study Groups, IADPSG. Several studies claimed that the diabetes-specific formula improved glycemic control in type 2 diabetes patients. However, the effects of medical nutrition therapy combined with the diabetes-specific formula in pregnant women with gestational diabetes mellitus (GDM) are unclear. Objective: This study examines whether medical nutrition therapy combined with Enteral Nutrition Suspension (TFP-DM, Diason 0.75 kcal/ml) in GDM women could improve the glycemic control and the pregnancy outcomes.
Detailed description
Design: A randomized controlled trial in pregnant women with gestational diabetes mellitus (GDM) will be performed at 24-28 weeks of gestation until the 42 days after delivery. Participants will be randomly assigned to the control group (Medical Nutrition Therapy) or the intervention group (Medical Nutrition Therapy combined with TFP-DM). The control group will receive the individualized Medical Nutrition Therapy, which focuses on restricting energy intake combined with behavioral lifestyle modification through participation in group sessions and individual counseling. The intervention group has two components. The first part has the same intervention with the control group. The second part has the additional Enteral Nutrition Suspension (TFP-DM, Diason 0.75 kcal/ml) intervention based on the standard Medical Nutrition Therapy. It meant 200ml/150Kcal TFP-DM will be suggested to participants in the intervention group 2 times per day. The 400ml TFP-DM will replace the 25 grams of grains and dairies during breakfast and the snack session after dinner. Overall, the control group and the intervention group will receive the same amount of carbohydrate and calorie intake. The primary outcome will be fasting plasma glucose concentration, HbA1c concentration. The secondary outcome will be serum glycated albumin, serum insulin concentration, the rate of using insulin for patients, the insulin sensitivity (HOMA-IS), the gestational weight gain, the incidence of macrosomic infants. Hypothesis: Medical nutrition therapy combined with the enteral nutrition suspension (TFP-DM, Diason 0.75 kcal/ml) in pregnant women with gestational diabetes mellitus (GDM) will improve in glucose and lipid metabolism and the relevant adverse pregnancy outcomes, and provide the evidence-based in clinical nutrition therapy for gestational diabetes mellitus (GDM) disease.
