Glucose Lowering effect Of Walking breaks during pregnancy
We are currently examining whether interrupting prolonged sitting during pregnancy can improve blood sugar levels in individuals at risk of gestational diabetes mellitus.
Recent experimental evidence suggests that regular (every 20–30 minutes), brief (2–3 minutes) bouts of gentle walking can lower post meal blood sugar levels by 24 to 35 per cent when compared to prolonged sitting. Given that prolonged sitting is associated with elevated blood sugar levels, there is value in examining the effect of breaking up sitting in the context of routine screening for gestational diabetes mellitus.
Who can participate?
Eligible participants must be pregnant, aged over 18 years and sit for more than 5 hours a day.
This study aims to test the acute effect of breaking up sitting during a pregnancy oral glucose tolerance test, a routine screening test used to diagnose GDM at 24–28 weeks.
Participants will be required to:
- Attend 3 visits (1 screening visit and 2 oral glucose tolerance tests) over a minimum period of 3 weeks.
- Provide blood samples at regular intervals (by means of intravenous catheter) during the oral glucose tolerance tests.
- Wear physical activity and continuous blood glucose monitors for a 4-day period on two occasions.
- Keep a record of your food and drink intake.
