Early Detection of Perinatal Depression With Wearable Technology (BLUESMAPPED)

21 de agosto de 2026 atualizado por: Women's College Hospital

Biometrics in Longitudinal Uptake for Early Monitoring and Assessing Perinatal Patterns of Emotions in Depression

The goal of this feasibility study is to learn whether wearable devices and self-report surveys can help researchers better understand changes in mood during pregnancy and after birth in young pregnant individuals with a history of major depressive disorder. The study will also examine whether this type of monitoring is practical and acceptable for participants and clinicians. The main questions it aims to answer are:

  • Can researchers successfully collect wearable and survey data throughout late pregnancy and the first 3 months after birth?
  • Do participants and clinicians find wearable-based monitoring easy to use and helpful?
  • Are changes in sleep, heart rate, activity, and other wearable data linked to mood changes during the perinatal period?

Researchers will compare 2 wearable devices, the Oura Ring and EmbracePlus, to see which device provides more complete and usable data.

Participants will:

  • Wear either the Oura Ring or EmbracePlus device every day from the third trimester of pregnancy until 3 months after birth
  • Complete short daily and biweekly questionnaires about mood and wellbeing
  • Allow the wearable device to collect information such as sleep, heart rate, heart rate variability, and physical activity

The study will include 10 participants. Researchers will measure feasibility by looking at how many participants join the study and how much study data is completed. The study team hopes at least 70% of scheduled study activities data will be collected.

Researchers will also interview 5 participants and 4 reproductive psychiatry clinicians about their experiences using wearable monitoring. These interviews will explore ease of use, usefulness in clinical care, and how wearable data may fit into electronic medical records.

This study may help researchers develop future tools that can predict the risk of perinatal depression earlier and support more personalized care during pregnancy and after birth.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Experimental: Oura Ring
Participants randomized to this arm will wear the Oura Ring continuously from the third trimester of pregnancy through three months postpartum. The device will collect sleep, activity, heart rate, and heart rate variability data passively, alongside daily and biweekly self-report measures.
Dispositivo: Oura Ring (Photoplethysmography-based wearable ring)
A lightweight titanium ring worn continuously on the index finger that passively collects sleep, physical activity, heart rate, and heart rate variability data via infrared optical sensors and a 3D accelerometer. Worn throughout the third trimester of pregnancy and three months postpartum to monitor physiological parameters associated with perinatal depression risk.
Comparador Ativo: EmbracePlus
Participants randomized to this arm will wear the EmbracePlus smartwatch continuously from the third trimester of pregnancy through three months postpartum. The device will collect sleep, activity, heart rate, heart rate variability, and electrodermal activity data passively, alongside daily and biweekly self-report measures.
Dispositivo: EmbracePlus Watch (Electrodermal activity wristband sensor)
A medical-grade waterproof smartwatch worn continuously on the wrist that passively collects sleep, physical activity, heart rate, heart rate variability, and electrodermal activity data via photoplethysmography and ventral electrodermal sensors. Worn throughout the third trimester of pregnancy and three months postpartum to monitor physiological parameters associated with perinatal depression risk.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Wearable device adherence completion rate
Prazo: From enrollment (13-27 weeks gestation) through 3 months postpartum
Feasibility of continuous wearable device data collection will be assessed by the proportion of scheduled data points completed during continuous daily wear. Wearable use profiles will be categorized as low, moderate, or high based on continuous daily wear without interruptions of more than 3 hours. Feasibility will be established if ≥ 70% of scheduled data points are completed across the study period.
From enrollment (13-27 weeks gestation) through 3 months postpartum
Daily Visual Analogue Scale mood entry completion rate
Prazo: From enrollment (13-27 weeks gestation) through 3 months postpartum
Feasibility of daily mood self-reporting will be assessed by the proportion of scheduled Visual Analogue Scale mood entries completed by participants. The Visual Analogue Scale is a 100-point scale (range: 0-100), where higher scores indicate better mood. Feasibility will be established if ≥ 70% of scheduled entries are completed across the study period.
From enrollment (13-27 weeks gestation) through 3 months postpartum
Edinburgh Postnatal Depression Scale completion rate
Prazo: From enrollment (13-27 weeks gestation) through 3 months postpartum
Feasibility of biweekly depression screening will be assessed by the proportion of scheduled Edinburgh Postnatal Depression Scale surveys completed. The Edinburgh Postnatal Depression Scale (EPDS) is a 10-item questionnaire (range: 0-30), where higher scores indicate greater severity of depressive symptoms. Feasibility will be established if ≥ 70% of scheduled surveys are completed across the study period.
From enrollment (13-27 weeks gestation) through 3 months postpartum
Generalized Anxiety Disorder-7 completion rate
Prazo: From enrollment (13-27 weeks gestation) through 3 months postpartum
Feasibility of biweekly anxiety screening will be assessed by the proportion of scheduled Generalized Anxiety Disorder-7 surveys completed. The Generalized Anxiety Disorder-7 is a 7-item questionnaire (range: 0-21), where higher scores indicate greater severity of anxiety symptoms. Feasibility will be established if ≥ 70% of scheduled surveys are completed across the study period.
