SLeeP AID4 is a single-group, single-arm, Canada-wide, non-randomised, unblinded, in-home, observational study to prospectively collect and build a data set of natural sleep behaviour and physiology in maternal-fetal dyads (and bed partners, if applicable) in the third trimester of pregnancy in the home setting and subsequently investigate the feasibility of using computer vision technology (CVT) to monitor sleep during and across the third trimester of pregnancy in the home setting for research purposes by eliciting participants' attitudes toward CVT and training, validating, and testing a CVT model to accurately, unobtrusively, non-invasively, and objectively detect and quantify various sleep behaviours, disturbances, and disorders.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Virtual setup cohort | Participants in this cohort will use a night vision camera and level III home sleep apnea test. If the participant has a bed partner who consents to be in the study, the bed partner will also use a level III home sleep apnea test and be recorded by the night vision camera. |
| |
| In-person setup cohort | Participants in this cohort will use a night vision camera, a level III home sleep apnea test, a maternal-fetal transabdominal electrocardiographic heart rate monitor, and a pressure sensing mat. If the participant has a bed partner who consents to be in the study, the bed partner will also use a level III home sleep apnea test and be recorded by the night vision camera (maternal-fetal transabdominal electrocardiographic heart rate monitor and a pressure sensing mat will not be used by the bed partner). |
