Brief Summary

It is well-known that regular physical activity (PA) can improve glycemic control and physical fitness in type 2 diabetes patients. However, studies examining the effects of PA in patients with gestational diabetes mellitus (GDM) are limited. Interval walking training (IWT) is a careful type of PA consisting of repeatedly cycles of 3 min. fast and slow walking. The investigators aimed to examine, if IWT is feasible as PA intervention for GDM patients, and to examine the effects of IWT on glycemic control, PA levels and physical fitness.

Behavioral: IWT-group

Con-group

NO INTERVENTION

The con-group follows the standardized GDM care program for GDM patients at OUH

Model Details: This open-label randomized controlled trial aims to enroll 20 patients randomized (1:1) to a control- (Con) or IWT-group. Patients in both the IWT- and Con-group follows the standardized GDM care program for GDM patients at OUH through the 6-week intervention period, which consists of instruction of self-monitoring of BG levels, dietary guidance, and in some cases, insulin treatment. Additionally, the program also consists of close obstetric control visits and exercise guidance. All patients are instructed not to start any new type of PA after inclusion and continue their lives without any changes. Patients randomized to the IWT-group goes through a 6-week non-supervised IWT-program, where they are prescribed to conduct 3 IWT sessions per week of 40-50 minutes each. Before and after the 6-week intervention, maternal blood glucose (BG) levels is measured by continuous glucose monitoring, PA level measured using accelerometers and physical fitness measured using two walking tests.
