As a prospective cohort study, CPS-3 follows the same group of participants for many years. With 300,000 participants from all over the US, the CPS-3 cohort is geographically and racially/ethnically diverse.
We collect Lifestyle, Behavioral, Health, and Environmental data from surveys. Participants receive follow-up surveys every 3 years for the next 20+ years that are distributed online and by mail and offered in English and Spanish.
Objectively measured using a variety of tools and devices, we use biometric data to validate or supplement participant-reported information.
Data is collected from activity monitors worn by up to 20,000 CPS-3 participants, making this study the largest of its kind in the United States
By securely linking participant information with state and national data sources, we have the capability of identifying additional data to advance our research.
This data includes cancer diagnoses from state cancer registries and mortality and cause of death from the National Death Index.
Through a secure participant portal, we are continuing to explore and add more types of data collection tools. All data are stored securely to safeguard privacy.
We compared self-reported physical activity and diet information with objective measures from activity trackers, blood and urine in 1,500 participants.
