Evaluating Association between Air Pollution and Cardiovascular Outcomes Using Smartphone Particle Sensors and Wearable Technologies in Children

摘要

Introduction: Recent development of both portable air pollution particle sensors and wearable technologies offers unique opportunities to study the real-time association between exposure and cardiopulmonary outcomes. We explored potential application of two technologies, AirBeam2 and Hexoskin smart shirt in a group of children. Methods: Elementary school aged children (N=12) in Albany, NY, are being equipped with particle sensor 'AirBeam2' (which measures PM1, PM2.5, and PM10), and a HexoSkin smart t-shirt (which measures heart rate, heart rate variability, breathing rate, ventilation) for a 1 week period, during all waking hours. Results: We will consider performance of AirBeam2 with stationary monitors, both a real-time instrument and integrated gravimetric filter system, previously placed within the classroom. The real-time relationship between exposure to PM and changes in heart rate variability, relative to baseline, will be measured and modeled using linear mixed models. We will also calculate lung deposited dose for PM using the measured lung function metrics from HexoSkin. Conclusion: Unique challenges were observed and experienced by researchers in this study assessing potential deployment of novel sensors in young children to study air pollution-health relationship. Preliminary results suggest that increased exposure to particulate matter exposure can potentially affect adversely cardiovascular outcomes among children.
