The Chronic Disease Prevalence and Health Behaviors slide set presents data on the prevalence of chronic diseases in San Diego County and its regions from 2001 to 2023, focusing on 3 health behaviors (poor diet, physical inactivity, and tobacco use) that contribute to 4 chronic diseases (cancer, heart disease, diabetes, and lung disease) that account for more than 50% of premature deaths (3-4-50 concept). The data provided in the slide set are from the Behavioral Risk Factor Surveillance System (BRFSS) and California Health Interview Survey (CHIS, AskCHIS).
