Remote data collection of infant activity and sleep patterns via wearable sensors in the HEALthy Brain and Child...

Area of Science:

• Neuroscience and Developmental Psychology
• Human Development Research
• Biomedical Engineering and Health Technology

Background:

• The HEALthy Brain and Child Development (HBCD) Study is a large-scale, multi-site, prospective longitudinal cohort study.
• Advancements in wearable and remote sensing technologies offer new possibilities for data collection outside traditional laboratory settings.
• Understanding the impact of early life experiences on development is crucial for identifying potential health and social outcomes.

Purpose of the Study:

• To examine human brain, cognitive, behavioral, social, and emotional development from prenatal stages through early childhood.
• To leverage wearable technologies for remote data collection on infant activity and sleep patterns within natural environments.
• To detail the framework guiding the study's design, data collection protocols, and the development of publicly available data derivatives.

Main Methods:

• Utilized wearable sensors to remotely measure infant activity (leg movements) and sleep (heart rate and leg movements).
• Employed a decision-making framework to establish the study design, data collection protocol, and derivative data generation.
• Examined challenges related to technology adoption, data management, participant privacy, and participant burden.

Main Results:

• Successfully illustrated the collection of infant activity and sleep data using wearable technologies in a naturalistic setting.
• Developed a comprehensive data collection protocol and derivative datasets for public dissemination.
• Identified and discussed practical challenges and limitations in wearable sensor data collection and analysis.

Conclusions:

• Wearable technologies provide a viable method for remote, in-home data collection in large developmental studies.
• The HBCD Study's approach offers a robust framework for integrating novel technologies into developmental research.
• Further research is needed to address validation, device comparability, and the impact of evolving sensor technology.
