Clinical Trial Summary

Gestational Diabetes Mellitus (GDM) incidence is increasing worldwide, and within Canada, the Atlantic provinces statistically have been found to have highest prevalence of diabetes. Increasing evidence supports the benefit of following a low glycaemic index (GI) diet in GDM and the Canadian Diabetes Guidelines recommends replacing high GI foods for low GI foods. Despite recommendation to adapt a low GI diet in GDM, there are limitations and barriers recognized to GI utility largely focused on knowledge translation. There is sufficient research to support a low GI diet in benefiting outcomes of GDM, therefore the GI in GDM Online trial will investigate the feasibility and effectiveness of a distance low GI education intervention, adapted from Diabetes Canada's GI materials, on producing a difference in average dietary GI between a group with the intervention and standard care.

Clinical Trial Description

The incidence of Gestational Diabetes Mellitus (GDM) has been progressively increasing worldwide, with a global prevalence of gestational hyperglycaemia estimated at 16.9%. In Canada, Atlantic provinces have been recorded with the highest prevalence of diabetes at 6%. The Diabetes Canada Practice Guidelines recommends the low glycemic index (GI) diet to type 1 and 2 diabetes mellitus and has recently updated its guidelines to include a recommendation for GDM. This said, barriers to GI knowledge translation have been identified. This study uses a prospective parallel randomized control trial design. Procedures and materials have been adapted from NCT01589757. The Kirkpatrick Model (Reaction, Learning, Behaviour, and Results) informed intervention development and evaluation strategies. The purpose of this study is to evaluate whether a distance low GI education intervention, adapted from Diabetes Canada's GI education materials, will significantly yield a lower average GI (primary outcome) in participants than traditional standard care medical nutrition therapy for Gestational Diabetes Mellitus. We hypothesize that participants who receive the low GI intervention will have a lower dietary GI than those who received usual IWK standard care for GDM. ;
