More than 13 million California adults — nearly half of the state’s adult population — are estimated to have prediabetes or undiagnosed diabetes, according to the 2013-14 California Health Interview Survey conducted by the UCLA Center for Health Policy Research. Another 2.5 million have been diagnosed with diabetes.
Prediabetes is a condition in which blood glucose levels are higher than normal but not high enough for a diagnosis of diabetes. People with prediabetes have a much higher risk of developing type 2 diabetes, as well as an increased risk for cardiovascular disease, though the concept of prediabetes as a medical condition is somewhat controversial.
Prediabetes disproportionately affects certain racial and ethnic groups. In California, at least half of Pacific Islanders, American Indians and African-Americans are estimated to have prediabetes, as shown in the graph above. According to the same data collected in the 2013-14 California Health Interview Survey, more than one-third of Latinos, Pacific Islanders, American Indians, African-Americans and those of multiple races aged 18-39 are estimated to have prediabetes.
