First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is tracking 2,000 adults over time to understand how obesity and disruptions to the body's internal clock (circadian rhythm) influence aging and heart health. Participants will provide health data, questionnaires, and biological samples during annual check-ups. The goal is to uncover links between weight, sleep patterns, and long-term health outcomes.
