Understanding population-wide trends in prevalence and control of diabetes is critical to planning public health approaches for prevention and management of the disease.To determine trends in prevalence of diabetes and control of risk factors in diabetes among US adults between 1999-2000 and 2017-2018.Ten cycles of cross-sectional National Health and Nutrition Examination Survey (NHANES) data between 1999-2000 and 2017-2018 were included. The study samples were weighted to be representative of the noninstitutionalized civilian resident US population. Adults aged 18 years or older were included, except pregnant women.Survey cycle.Diabetes was defined by self-report of diabetes diagnosis, fasting plasma glucose level of 126 mg/dL or more, or hemoglobin A1c (HbA1c) level of 6.5% or more. Three risk factor control goals were individualized HbA1c targets, blood pressure less than 130/80 mm Hg, and low-density lipoprotein cholesterol level less than 100 mg/dL. Prevalence of diabetes and proportion of adults with diagnosed diabetes who achieved risk factor control goals, overall and by sociodemographic variables, were estimated.Among the 28 143 participants included (weighted mean age, 48.2 years; 49.3% men), the estimated age-standardized prevalence of diabetes increased significantly from 9.8% (95% CI, 8.6%-11.1%) in 1999-2000 to 14.3% (95% CI, 12.9%-15.8%) in 2017-2018 (P for trend
