Rancho Bernardo Study (RBS)
The RBS study is a long-running longitudinal cohort study based in Rancho Bernardo, a suburb of San Diego, California, the United States of America. Over 6,700 participants were initially recruited between 1972 and 1974 to investigate cardiovascular risk factors. The study was later expanded to examine broader aspects of aging. Participants were recruited through door-to-door outreach and community engagement as part of the Lipid Research Clinic (LRC) Prevalence Program, with free health screenings conducted in a mobile clinic set up in a supermarket parking lot. To date, the study has conducted 12 clinic visits, with participants followed up through clinic visits approximately every 4 years, mailed surveys every 2 years, and annual checks on vital status.
