Data from U.S. adults aged ≥20 y in NHANES 1988–1994, 1999–2004, and 2005–2010. Total confirmed diabetes was defined as diagnosed diabetes or undiagnosed diabetes with diagnostic levels of both hemoglobin A1c (≥6.5%) and fasting glucose (7.0 mmol/L [≥126 mg/dL]). Obesity was defined as body mass index ≥30 kg/m 2; 601 persons were missing body mass index data. Prevalence estimates for total confirmed diabetes and obesity were obtained using only the subsample of participants who attended the morning fasting session (7385 participants for 1988–1994, 5680 participants for 1999–2004, and 6719 participants for 2005–2010). The midpoint for obesity prevalence between 1988–1994 and 1999–2004 was calculated as the average of the prevalence of the 2 Ann Intern Med. 2014;160(8):517-525. doi:10.7326/M13-2411 periods.
