In this video, we delve into the growing significance of wearable technology in the realm of population health. Ten years ago, less than 10% of the population owned and used a wearable device such as an Apple Watch, Fitbit, or Garmin. Today, nearly two-thirds of the population utilise these devices daily, contributing to an unprecedented volume of biometric data collection.
Our investigation provides a comprehensive overview of the current landscape of wearable technology research. We conducted an umbrella review of systematic reviews, scrutinising 24 systematic reviews encompassing 391 unique studies. These studies evaluated various commercially available wearable devices for their accuracy in measuring biometric outcomes.
Key findings reveal that wearables exhibit high accuracy in metrics related to the cardiovascular system, including heart rate (BPM) and blood oxygen saturation (SpO2). Wearables demonstrate good accuracy for estimating heart rate variability (HRV) and aerobic capacity (VO2max) during exercise testing. However, discrepancies arise due to factors such as device type, participant characteristics, activity intensity, and skin tone.
Key Abbreviations:
- BPM: Beats Per Minute
- SpO2: Blood Oxygen Saturation
- HRV: Heart Rate Variability
- VO2max: Maximum Oxygen Uptake
- ICC: Intraclass Correlation Coefficient
