The Centers for Disease Control and Prevention (CDC) located within the Department of Health and Human Services (HHS) announces the launch of the Healthy Behavior Data Challenge.
The Healthy Behavior Data Challenge responds to the call for new ways to address the challenges and limitations of self-reported health surveillance information and tap into the potential of innovative data sources and alternative methodologies for public health surveillance.
The Healthy Behavior Data (HBD) Challenge will support the development and implementation of prototypes to use these novel methodologies and data sources (e.g., wearable devices, mobile applications, and/or social media) to enhance traditional healthy behaviors surveillance systems in the areas of nutrition, physical activity, sedentary behaviors, and/or sleep among the adult population aged 18 years and older in the US and US territories.
The collection of health data through traditional surveillance modes including telephone and in-person interviewing, however, is becoming increasingly challenging and costly with declines in participation and changes in personal communications. In addition, the self-reported nature of responses particularly in the areas of nutrition, physical activity, sedentary behaviors, and sleep has been a major limitation in these surveillance systems, since self-reported data are subject to under/over reporting and recall bias. Meanwhile, the advent of new technologies and data sources including wearable devices ( such as: smart watches, activity trackers, sleep monitors, etc.), mobile health applications on smartphones or tablets, and data from social media represents an opportunity to enhance the ability to monitor health-related information and potentially adjust for methodological limitations in traditional self-reported data.
The Healthy Behavior Data (HBD) Challenge will be conducted concurrently with a similar challenge proposed by the Public Health Agency of Canada. This will enable the two countries to learn from their respective challenges and leverage information. We expect increased efficiency with a dual challenge.
The Healthy Behavior Data Challenge participants will propose data sources and approaches for aggregating data from wearable devices, mobile applications and/or social media in the areas of nutrition, physical activity, sedentary behaviors, and/or sleep. In Phase II (Prototype Implementation), a subset of submissions (up to 3) with promising concepts will be invited to test their proposed approaches for ongoing public health surveillance.
Winner: Catherine Bass
Solution: Onlife Health - Closing the Loop
Description: Augmenting Mobile Data Sources for Public Health Surveillance The system was designed to simplify and improve the quality and quantity of health behavior data collection by aggregating personal wearable device and mobile health app data, augmented by user validation and supplemented with survey responses. The mobile app was designed to collect and validate data from wearable devices and mobile apps and to collect survey responses on healthy behaviors. The data collected include nutrition, sleep, physical activity and sedentary behaviors. The project included a series of short, just-in-time survey questions delivered via push notification to supplement mobile data sources. The system cross-validated the collected healthy behavior data from the mobile and survey data sets, as well as with the BRFSS survey data. Robert Furberg - RTI International - Enhancing Public Health Surveillance Indicators using Wearable Devices The method was designed to augment any mode of data collection, from interviewer-administered in-person or telephone surveys to self-administration online or via mobile device, with minimal disruption to these essential data collection activities. The project demonstrated how the combination of self-generated data can enhance public health surveillance indicators to provide valid, measures of physical activity, sedentary behaviors, and sleep. The approach implemented a three-step data collection: screening, survey, and data retrieval. Owners of Fitbit devices were invited to participate in the HBDC. A service called Fitabase was used for data retrieval of the three measures.

Phase II (Prototype Implementation Phase)
During The Phase II Prototype Implementation Phase, the six submissions selected under Phase I will test their solutions, utilizing data from 300 or more adults (aged 18 and above) residing in the US or its territories. During this phase there will be an opportunity for HBD Challenge participants to incorporate data from existing surveys including the Behavioral Risk Factor Surveillance System (BRFSS).
Phase II (Prototype Implementation) allows applicants to test proposals developed in Phase I. The prototype is a demonstration of possible methods for supplementing data from existing surveillance systems (such as the BRFSS). This prototype is not meant to be merged with existing surveillance systems, but rather to complement data collected with current infrastructures. At the end of implementation HBD Challenge participants should be able to:
- Compare data obtained by the prototype to data from the BRFSS in the areas of nutrition, physical activity, sedentary behaviors, and/or sleep.
- Demonstrate how data from the included participants could be stratified by demographics (age, sex, education, etc.).
- Demonstrate the ease of adding additional types of mobile applications and wearable devices to existing survey methodologies.
- Report that describes the prototype/methodology and the prototype’s anticipated strengths and limitations for surveillance.
- Demonstrate the applicability of the non-traditional data source(s) for ongoing public health surveillance purposes.
- Describe the prototype in detail, including purpose, method, outcomes and comparability to data obtained from the Behavioral Risk Factor Surveillance System (BRFSS).
- Provide a working prototype including data (in Excel format) obtained using the prototype from 300 or more adult respondents residing in the US or its territories. The data must include the age, gender, location, and at least one of the measures associated with the HBD Challenge in the areas of nutrition, physical activity, sedentary behaviors and/or sleep.
- Provide a PowerPoint presentation to the judges and invited CDC personnel which includes information on the purpose, methods, outcomes and comparability to the BRFSS.
