Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The 2019 Canadian Guideline for Physical Activity throughout Pregnancy recommends that women be physically active for at least 150 minutes spread over at least 3 days each week. Managing high blood sugars with exercise improves outcomes for mom and baby; however, optimal timing of exercise has not been investigated.
The goal of this study is to determine if exercising after meals in shorter bouts is more effective at controlling post-meal blood sugars than exercising in larger amounts between meals.
This is a fully remote study; participants will receive all necessary equipment in the mail and all interactions with the researcher will be done via phone, video call and email.
The study will recruit 30 pregnant women diagnosed (or not) with diabetes (gestational, pre-, or type 2 diabetes mellitus) after 20 weeks' gestation to participate in this 2-week study. Following a 2 day baseline period, they will be randomly assigned to: 1) walk for 10 minutes after each meal (SHORT), or 2) walk for 30 minutes once per day at any time except in the hour after eating (LONG) for 5 days. Following a 2- day washout period, women will then complete the alternative exercise protocol for an additional 5 days. Women will wear a Continuous Glucose Monitor to track blood sugars, and an accelerometer to track activity patterns (e.g., compliance to the intervention) for seven consecutive days. The Investigators hypothesize that women who walk for 10 minutes after each meal will have a blunted rise in blood sugar following food intake, compared to the women in the 30- minute walking group. Findings from this novel study may help better treat GDM, improving lifelong health for moms and babies around the world.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Diabetes
Participants recruited to this arm have been clinically diagnosed with either gestational, pre- or type 2 diabetes.
30-minute walking intervention
Participants are asked to go for a 30 minute walk once per day at any time except the 1 hour after a meal. During these walks they are asked to record heart rate using a heart rate monitor and a phone application.
10-minute
Participants are asked to go for a 10-minute walk after each meal occurring 3 times daily. During these walks they are asked to record heart rate using a heart rate monitor and a phone application.
Non-diabetes
Participants recruited to this arm of the study do not have gestational, pre- or type 2 diabetes.
30-minute walking intervention
Participants are asked to go for a 30 minute walk once per day at any time except the 1 hour after a meal. During these walks they are asked to record heart rate using a heart rate monitor and a phone application.
10-minute
Participants are asked to go for a 10-minute walk after each meal occurring 3 times daily. During these walks they are asked to record heart rate using a heart rate monitor and a phone application.
