About All of Us Participants

The All of Us Research Program aims to engage a community of one million or more volunteers who reflect the diversity of America.

We recruit participants, both healthy and those who have experienced illness, from all regions across the country, including many communities that have traditionally been underrepresented in biomedical research.

These diverse participants contribute to a wide variety of data sources including surveys, measurements, biosamples, electronic health records (EHRs), and mobile health devices.

The All of Us Research Program’s Data and Research Center curates and validates participant data as part of the data collection process.

Through the All of Us Research Hub, researchers can explore participant data by state, ethnicity, age, and more through our Data Snapshots or Data Browser.

SURVEYS

All participants who consent to be a part of the program must complete a core set of surveys on the secure Participant Portal (learn more about how participants join here). Some participants will complete more health surveys during their participation in the program.

Core surveys include extensive questions on health and lifestyle factors. Additional surveys will be incorporated over time by the program. You can view survey questions and learn more about where they came from using our Survey Explorer.

ELECTRONIC HEALTH RECORDS

Some participants will agree to share information from their electronic health records (EHR). The program removes personal identifiers from EHR data before adding this information to the Research Hub

We use the Observational Medical Outcomes Partnership (OMOP) to standardize all EHR data. Learn more about OMOP on our Data Methods page.

PHYSICAL MEASUREMENTS

Some participants will provide physical measurements at one of our All of Us Research Program Partner locations. Measurements collected include: height, weight, BMI, waist circumference, hip circumference, pregnancy-status, blood pressure, heart rate, and wheelchair use.

Further explore our collection of physical measurements in the Data Browser.

BIOSAMPLES

Some participants contribute urine and saliva samples. These samples are stored in our biobank at the Mayo Clinic for later analyses, including genomic sequencing. In the future, genetic data will become available on the Research Hub for registered and approved researchers.

MOBILE HEALTH DATA (WEARABLE DEVICES)

The program also has begun collecting information from wearable health tracking technology. Wearables track biometric data like heart rate and blood pressure.
