age adjusted prevalence of diabetes
64.6 percent of adults aged 18 years and older with diagnosed diabetes had a glycosylated hemoglobin measurement at least twice in the past 12 months, as reported in 2008 (age adjusted to the year 2000 standard population). Overall Numbers, Diabetes and Prediabetes. 1  Prevalence: In 2012, 29.1 million Americans, or 9.3% of the population, had diabetes. 2  Approximately 1.25 million American children and adults have type 1 diabetes. 3  Undiagnosed: Of the 29.1 million, 21.0 million were diagnosed, and 8.1 million were undiagnosed.

Mozaffarian D et al. Circulation. 2015;131:e29-e322 National Health and Nutrition Examination Survey: 2009–2012. Nearly 1 in 10 adults now have this chronic disease. Many more are unaware that they have this condition. According to national studies, approximately one-third of people with diabetes do not know they have it. 15 The continued rise in diabetes prevalence is likely due to a combination of factors. The most important factor is the increase in adult obesity, which is the main driver of the diabetes epidemic. Furthermore, women who have had GDM have a 35% to 60% chance of developing type 2 diabetes within the next 10 to 20 years. 6 The prevalence of GDM has been increasing both nationally and in LA County, 10,11 and parallels the trend in type 2 diabetes. Baseline: 68.0 percent of adults aged 18 years and older with diagnosed diabetes had at least one foot examination by a health professional in the past 12 months, as reported in 2008 (age adjusted to the year 2000 standard population). Target: 1 Prevalence in Seniors: The percentage of Americans age 65 and older remains high, at 25.9%, or 11.8 million seniors (diagnosed and undiagnosed). 2  New Cases: The incidence of diabetes in 2012 was 1.7 million new diagnoses/year; in 2010 it was 1.9 million. 51.8 percent of adults aged 18 years and older with diagnosed diabetes had their blood pressure under control in 2005–08 (age adjusted to the year 2000 standard population). From 1997 to 2011, the percentage of adults with this condition increased from 6.6% to 9.9%; 1-3 more than 685,000 adults in the county are now affected. Obesity is the primary preventable risk factor for type 2 diabetes, 4 which accounts for over 90% of all diabetes cases. Age and Racial/Ethnic Disparities • Diabetes increased with age: In 2011 the prevalence was 3.7% for adults ages 30-39 years and increased to 24.1% for those 65 years and older (Table 1).• Diabetes prevalence was highest among Latinos (13.5%) and African Americans (12.4%); it was lowest among whites (6.7%).
