Active Comparator: Deactivated device
Wear deactivated pregnancy coach device for the remainder of pregnancy.
|
Device: Deactivated Pregnancy Coach
Naturalistic monitoring of their typical sleep patterns and behaviors |
Experimental: Active device
Wear active device for remainder of pregnancy (including 3 day run-in period)
|
Device: Active Pregnancy Coach
The Pregnancy Coach will begin to deliver alerts when supine sleep is detected. Sleep metrics will be visible on the smartphone app. |
- Proportion of sleep time spent in the supine position as measured by the Pregnancy Coach [ Time Frame: Until delivery, approximately 12 weeks ]Will be conducted using the naturalistic arm (deactivated device). Simple descriptive statistics to report the average number of minutes and the average proportion of supine sleep per week.
- Proportion of sleep time spent with objective snoring as indicated by the Pregnancy Coach [ Time Frame: Until delivery, approximately 12 weeks ]Will be conducted using the naturalistic arm (deactivated device). Proportion of time will be determined during each gestational week.
- Proportion of participants where their 'going to sleep' position was the same as their dominant sleep position [ Time Frame: Until delivery, approximately 12 weeks ]Will be conducted using the naturalistic arm (deactivated device). We will determine whether the "going to sleep" position during each gestational week is predictive of the most dominant sleep position.
- Percentage of sleep position changes following alert from Pregnancy Coach [ Time Frame: Until delivery, approximately 12 weeks ]Will be conducted using the intervention arm (active device). Percentage of sleep position changes in response to an alert from the Pregnancy Coach will be reported for each gestational week.
