Why is chronic disease prevention important to health?
Chronic diseases such as heart disease, diabetes, obesity, and cancer are long-term conditions that often require ongoing medical attention and can significantly impact daily life. These conditions reduce quality of life, increase the risk of premature death, and contribute significantly to healthcare costs. However, many chronic diseases are preventable through early intervention, healthy behaviors, and consistent access to regular healthcare.
Preventing chronic disease is essential for improving both individual well-being and community health. Without timely intervention, these conditions can lead to serious complications, disability, and impose a heavy burden on families, healthcare systems, and the broader economy. For example, one study found that 37% of Hispanic/Latino adults with diabetes were undiagnosed, with individuals of Cuban and South American heritage facing significantly higher odds of undiagnosed diabetes compared to those of Mexican heritage 2. Over time, undiagnosed and untreated diseases increase the risk of more serious complications, loss of work productivity, and diminished overall health, further adding to the social and economic impact.
How do the goals align with the San Bernardino Countywide Vision?
Improving chronic disease outcomes is central to the San Bernardino Countywide Vision as it supports long-term community health and equity. Through the Community Transformation Plan, the County is committed to tackling root causes of chronic illness, including limited access to healthy foods, opportunities for physical activity, and preventive healthcare services. These efforts aim to promote wellness, reduce health disparities, and ensure that every resident can live a longer, healthier life.
What did the data show?
Chronic disease continues to be a pressing issue in San Bernardino County. In California, heart disease was the leading cause of death in 2021. Locally, high cholesterol was the most common chronic condition among adults, and rates have continued to rise in recent years.
San Bernardino County ranks poorly among California’s 58 counties, including 48th for chronic respiratory disease, 47th for coronary heart disease, and 42nd for all cancers. Obesity among adults in the County increased significantly from 28% in 2017 to 31% in 2021, far above the state average of 24%1. In that same year, 24% of adults rated their own health as poor or fair, compared to 18% across the state 1. High cholesterol affected 32% of adults in 2021, up from 27% in 2017, while 30% of adults were reported to have high blood pressure.
These findings emphasize the urgent need for targeted prevention efforts, accessible healthcare, and community-based support. Tackling chronic disease is not only about managing conditions, it is about creating healthier, more equitable environments for all residents of San Bernardino County.
