Official title: Integrating Smart Ring Wearable Technology in Pregnancy Health Monitoring (I-SMART)

Status Not yet recruiting

Clinical Trial Summary

This study aims to test the following hypotheses in a single-arm observational study in 70-100 healthy pregnant multi-ethnic women who will be followed-up from the first trimester of pregnancy to the third trimester of pregnancy.

Aim 1: To assess the applicability, acceptability and compliance with the use of a wearable smart ring together with smart digital devices (e.g., smart phone) during pregnancy.

Hypothesis 1: The investigators hypothesize that participants will respond favorably to the use of the smart ring to monitor their physical activity and sleep during pregnancy.

Aim 2: To assess the association between maternal characteristics (age, pre-pregnancy BMI, pregnancy weight gain, stress, anxiety and depression symptoms) with physical activity markers (energy expenditure, and step count) and sleep markers (duration, quality, sleep onset latency, wake after sleep onset, time in bed and heart rate variability) collected from the smart ring in the second trimester of pregnancy.

Hypothesis 2: The investigators hypothesize that specific maternal characteristics will be associated with physical activity markers (energy expenditure, and step count), as well as sleep markers (duration, quality, sleep onset latency, wake after sleep onset, time in bed and heart rate variability).

Clinical Trial Description

Wearable sensor and other smart technologies may play an important part in the early detection of adverse pregnancy-related health events along with motivating improvement in patient and provider interactions for effective pregnancy health management. The use of wearable sensors, more specifically, wearable smart rings can potentially be used to offer remote, unobtrusive personalized care, encourage preventive care and provide the necessary context for self-help based just-intime adaptive interventions (feedback loops utilizing digital phenotyping data to trigger in-app interventions). Studies on the use of wearable smart rings and health outcomes are scarce, and currently there is no available data of the use of wearable smart rings together with smart digital devices (i.e., smart phone) for tracking pregnancy health in women. This study aims to be the first to generate preliminary pilot data to support it's use in this specific group of women.

An observational period for up to 37 weeks, single-center, one-armed intervention study involving 70-100 healthy pregnant women from a multi-ethnic population (Chinese, Malay, Indian, others) aged between 21 and 45 years.

All participants included into the study will be provided an Oura Ring to wear for the rest of the pregnancy period.

Data will be collected through questionnaires and each time a participant opens up their mobile application, the uploaded data will be automatically transferred via Bluetooth connection to the study database in the smart ring cloud service. The questionnaires include socio-economic factors, maternal anxiety and depression, maternal sleep, and maternal physical activity. The participants data will be collected from the moment join the study up till delivery. ;
