The All of Us Research Program is a national initiative aimed at gathering health data from a diverse group of people across the United States. Its goal is to improve health outcomes by understanding how individual differences in lifestyle, environment, and biology affect health. Participants contribute information through surveys, health records, and biosamples, which researchers can use to advance precision medicine. This program is part of the larger effort by the National Institutes of Health to create a comprehensive database that reflects the diversity of the U.S. population. By including various demographics, the program seeks to ensure that medical research benefits everyone, not just specific groups.
