Wearable devices are fundamentally
changing primary data collection, enabling
low-cost, distributed, passive, longitudinal
monitoring of human performance, health
behaviors, and other indicators.

Add Health Consumer Wearable Ancillary Study
CONFIDENTIAL17
▪ Aim 1: Determine rates of smartphone and consumer wearable device
adoption within the Add Health cohort.
▪ Aim 2: Invite cohort members identified in Aim 1 to make a one-time
donation of historical data collected using personally owned wearable
devices.
▪ Aim 3: Prepare a harmonized dataset
▪ Aim 4: Conduct preliminary analysis of wearables data, including device
types, duration and consistency of tracking, and physical activity outcomes.

Healthy Behavior Data Challenge
CONFIDENTIAL18
▪ The Healthy Behavior Data Challenge explores the potential of innovative
data sources and alternative methodologies for public health surveillance.
▪ Our approach emphasizes how consumer wearable data can be used to
augment BRFSS measures with a focus on physical activity, sedentary
behaviors, and sleep
▪ RTI was a Phase I winner and submitted a Phase II dataset to CDC on
January 31, 2018
