Chronic Disease

Highest Rates of Chronic Diseases Among Counties

Chronic diseases – including diabetes, high blood pressure, and cardiovascular (heart disease) – are costly yet largely preventable. Chronic illnesses contribute to approximately 70% of deaths in the United States each year and account for about 75% of the nation’s health-related costs.1 This indicator reports prevalence and death data for heart disease, diabetes, and high blood pressure/stroke. Also tracked are hospitalizations due to heart disease.

Hospitalizations due to Coronary Heart Disease

In 2017, the hospitalization rate for heart disease in San Bernardino County was 86.6 per 10,000 residents (age-adjusted). This is significantly higher than the California hospitalization rate of 69.5 per 10,000 residents.

Note: This report presents longitudinal data for hospitalizations using 2008-2017 Census (ACS) population estimates. The San Bernardino County Community Transformation Plan also presents data related to heart disease hospitalizations. Because that plan presents a one-year snapshot for 2012, using 2010 Census population, the rates are not directly comparable.

Thus, caution should be taken when interpreting the data. 3Fully 70% of strokes can be directly linked to existing high blood pressure, making high blood pressure the single most important controllable stroke risk factor.
