Includes physician-diagnosed and undiagnosed diabetes. Physician-diagnosed diabetes was obtained by self-report and excludes women who reported having diabetes only during pregnancy. Undiagnosed diabetes is defined as a fasting blood glucose (FBG) of at least 126 mg/dL and no reported physician diagnosis. In 2005–2006, FBG testing was performed at a different laboratory and using a different instrument than testing in earlier years. NHANES conducted a crossover study to evaluate the impact of these changes on FBG measurements. As a result of that study, NHANES recommended that 2005–2006 data on FBG measurements be adjusted to be compatible with earlier years. Undiagnosed diabetes estimates in Health, United States were produced after adjusting the 2005–2006 FBG data as recommended. For more information, see http://www​​/data/nhanes/nhanes_05_06/glu_d.pdf. See related Table 51.


Estimates are age-adjusted to the year 2000 standard population using three age groups: 20–39 years, 40–59 years, and 60 years and over. Because of the smaller sample size for fasting tests, age adjustment is to three age groups only. Age-adjusted estimates in this table may differ from other age-adjusted estimates based on the same data and presented elsewhere if different age groups are used in the adjustment procedure. See Appendix II, Age adjustment.


High serum cholesterol is defined as greater than or equal to 240 mg/dL (6.20 mmol/L). Risk levels have been defined by the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults. National Heart, Lung, and Blood Institute, National Institutes of Health. September 2002. (Available from: http://www​.nhlbi.nih​.gov/guidelines/cholesterol/index.htm and summarized in JAMA 2001;285(19):2486–97.) Individuals who take medicine to lower their serum cholesterol levels and whose measured total serum cholesterol levels are below the cut-offs for high cholesterol are not defined as having high cholesterol. See related Table 69.


Age-adjusted to the 2000 standard population using five age groups: 20–34 years, 35–44 years, 45–54 years, 55–64 years, and 65 years and over. Age-adjusted estimates may differ from other age-adjusted estimates based on the same data and presented elsewhere if different age groups are used in the adjustment procedure. See Appendix II, Age adjustment.


Hypertension is defined as having elevated blood pressure and/or taking antihypertensive medication. Elevated blood pressure is defined as having systolic pressure of at least 140 mmHg or diastolic pressure of at least 90 mmHg. Those with elevated blood pressure may be taking prescribed medicine for high blood pressure. Respondents were asked, “Are you now taking prescribed medicine for your high blood pressure?” See Appendix II, Blood pressure, elevated. See related Table 68.


Excludes pregnant women. Overweight is defined as body mass index (BMI) greater than or equal to 25 kilograms/meter2. See Appendix II, Body mass index. See related Table 72.


Excludes pregnant women. Obesity is defined as body mass index (BMI) greater than or equal to 30 kilograms/meter2. See Appendix II, Body mass index. See related Table 72.


Untreated dental caries refers to untreated coronal caries, that is, caries on the crown or enamel surface of the tooth. Root tips are classified as coronal caries. Root caries are not included. For children 2–5 years of age, only dental caries in primary teeth was evaluated. Caries in both permanent and primary teeth was evaluated for children 6–11 years of age. For children 12 years and over and for adults, only dental caries in permanent teeth was evaluated. Persons without at least one primary or one permanent tooth or one root tip were classified as edentulous and were excluded from this analysis. The majority of edentulous persons are 65 years of age and over. Estimates of edentulism among persons 65 years of age and over are 33% in 1988–1994 and 27% in 1999–2004. Because of significant methodological changes in the collection of 2005–2006 data on dental caries, the 2005–2006 data are not comparable with earlier years. Therefore, 2005–2006 data are not presented in Health, United States. For more information, see http://www​​/data/nhanes/nhanes_05_06/ohx_d.pdf. See Appendix II, Dental caries. See related Table 74.


Overweight is defined as body mass index (BMI) at or above the sex- and age-specific 95th percentile BMI cutoff points from the 2000 CDC Growth Charts: United States. Advance data from vital and health statistics; no 314. Hyattsville, MD: National Center for Health Statistics. 2000. Excludes pregnant girls. See related Table 73.
