Diabetes occurs when the body does not produce enough insulin or cannot use its own insulin well enough to reduce sugar (glucose) levels in the blood. Adult, or type 2, diabetes occurs in adulthood, usually in people who are overweight or obese. Uncontrolled diabetes can lead to serious complications, such as blindness and other eye problems, kidney disease, neurological damage, hypertension, heart disease, stroke, and certain cancers. Uncontrolled diabetes can also cause poor circulation, which in turn can lead to foot amputation.1
More than two million adults in California have reported that they were diagnosed with diabetes in adulthood.2 Diabetes is the seventh leading cause of death in the United States, and accounts for more than 20% of health care spending.1
Before people develop type 2 diabetes, they almost always have prediabetes, a condition that is often undetected or not diagnosed.3 Prediabetes is associated with a higher risk for developing type 2 diabetes and cardiovascular disease. However, it can be reversed with diet, physical activity, and weight loss. Prediabetes therefore presents a prime opportunity for prevention.
Findings in Santa Barbara County
The prevalence of adult diabetes was measured by asking respondents if they had ever been told by a doctor or other health professional that they had diabetes (or “sugar diabetes;” female respondents were instructed to exclude pregnancy-related diabetes). Responses from persons who said they had "borderline" or "prediabetes" were added to the first question and combined for the final percentages in this section, as prediabetics are an important group to target for preventive interventions.

Note: Analyses in this Health Profile include adults with diabetes or prediabetes. The rate of diabetes in CA is 10.3% and prediabetes is 2.6%. In Santa Barbara County, the rate of diabetes is 8.8% and prediabetes is 1.3%.

At 10%, Santa Barbara County's percentage of adults with diabetes/prediabetes is lower than California's, but higher than the HP 2020 target of 7.2%. Approximately 1% of Santa Barbara County adults have been diagnosed with prediabetes. The percentages are notably higher among people over 65 and those in the lowest income group.
Hispanics, in particular, have the highest prevalence of adult diabetes among all groups in Santa Barbara County. Their rate is twice as high as that of whites and double the HP 2020 target.

Factors and Health Outcomes Associated with Diabetes
Figure 47 presents various individual, social, and environmental factors that contribute to the development of diabetes in the population, selected health outcomes that are associated with diabetes, and factors that contribute to successful management of the disease.
Modifiable risk factors for diabetes include diet, being overweight and obese, and insufficient physical activity.1 The figure compares people who have diabetes or prediabetes with all adults in the Santa Barbara County survey and with Californians as a whole.

*Data for California are not available for all indicators
The chart shows that there are some significant differences between Santa Barbara County and California overall. Twice as many Santa Barbara County adults with diabetes or prediabetes report poor health, as well as higher rates of strokes, cancer, and mental health issues. They are more likely to be obese, less likely to have a high school degree, and experience higher rates of food insecurity relative to Santa Barbara County overall. However, they are more likely to have a primary care provider.
