Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* Is sleep disordered breathing associated with impaired the function of the heart and blood vessels in pregnancy?
* Is higher levels of physical activity associated with a reduced risk of sleep disordered breathing in pregnancy?
Participants will complete an 8 day long study protocol at two time points during pregnancy (20-24 weeks gestation and 28-36 weeks gestation). During each testing period they will be asked to:
* Complete one night of at-home sleep testing and and one night of overnight vital signs monitoring (ambulatory blood pressure and heart rate monitoring devices)
* Wear two accelerometers and complete a 7-day sleep log
* Complete a set of questionnaires
* Visit the laboratory for a fasted blood draw and ultrasound assessment of their cardiovascular health (resting heart rate and blood pressure, flow mediated dilation and pulse wave velocity tests)
Participants will also be asked to complete a short follow-up survey in the postpartum period.
