Descriptive Information
Brief Title  ICMJE Food Order Intervention for Gestational Diabetes
Official Title  ICMJE Carbohydrate-Last Food Order Intervention for Gestational Diabetes Mellitus
Brief Summary This is a randomized controlled feasibility trial for women diagnosed with gestational diabetes mellitus (GDM). The current front-line treatment for GDM is medical nutrition therapy (MNT), i.e. personalized diets which may or may not include mild carbohydrate restriction. Use of carbohydrate restriction increases the risk of the mother developing ketosis, a harmful condition for both the mother and fetus. If MNT is not enough to stabilize blood sugar levels, then pharmaceuticals are prescribed. In patients with type-2 diabetes and prediabetes, the carbohydrate-last food order behavior has been shown to improve post-meal blood sugar control without the need of reduced carbohydrate intake. Given this data, the addition of this intervention to MNT in patients with GDM may be helpful in achieving controlled blood sugar levels without increasing the risk of ketosis. This study will include two randomized groups diagnosed with GDM. Patients in the control group will be prescribed standard MNT. Patients in the intervention group will have identical MNT but with additional food order instruction/therapy. All patients will be followed up with at 1-2 week intervals. At each follow-up the physician and dietician will analyze the patient's blood sugar measurements and, among additional factors, determine if pharmaceuticals should be added. Treatment will continue through delivery. The primary aim of this study is to assess the feasibility of the carbohydrate last food order in GDM and generate preliminary data on its effects on glucose control.
