Longitudinal cohort study

A longitudinal cohort study is a research method where a group of people sharing a common characteristic (a "cohort") is followed over time to observe how specific factors or behaviors impact their health or outcomes. Researchers collect data at multiple points, allowing them to identify patterns or changes and establish possible cause-and-effect relationships. This approach helps to understand how things like lifestyle, environment, or genetics influence long-term health, providing valuable insights into disease development, prevention, and health trends.
