Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Women between 12-30 wks of pregnancy will be advised to perform 10-minutes of light-moderate intensity walking after each main meal. They will also receive standard-care from the Diabetes Service (as below control). The intervention will be from 12-35 wks of pregnancy until brith. Accelerometers will objectively measure physical activity.

Statistical methods / analysis
Data will first be assessed for normality using Q-Q plots, histograms and the shapiro-wilk test. A Linear mixed model (with intervention duration as a covariate) will compare the changes in study outcomes between the PMW and Control groups.

Summary
Brief summary
This project seeks to determine the feasibility and effectiveness of postmeal walking exercise to control blood glucose in gestational diabetes. Postmeal walking involves 10 min
of physical activity (preferably walking) after breakfast, lunch and dinner. Women with gestational diabetes will be randomised to standard-care alone, or with postmeal walking.
It is hypothesised that postmeal walking will improves aspects of blood glucose control more than standard-care alone.
