a Calculated for characteristics for which a population denominator was available
b Estimates for Hispanic and Asian subgroups cannot be calculated for 1999–2000 due to NHANES sampling methodology
cDefined using the ratio of family income to poverty (calculated by dividing family income by the U.S. Department of Health and Human Services poverty guidelines specific to the survey year); < 1 was considered below poverty
d Normal, prediabetes and diabetes were defined using the National Institutes of Health’s glycohemoglobin (A1C) cutoff values http://diabetes.niddk.nih.gov/dm/pubs/diagnosis/
e BMI categories for children and adolescents aged 2 to 19 years were based on the Centers for Disease Control and Prevention's sex-specific 2000 BMI-for-age growth charts for the United States http://www.cdc.gov/growthcharts/clinical_charts.htm. BMI for adults aged 20 years and older were based on Centers for Disease Control and Prevention’s standard weight status categories http://www.cdc.gov/healthyweight/assessing/bmi/adult_bmi/index.html
§ Estimates and 95% CIs may be unreliable because the RSE > 30%
Note: There were no study participants with both TST positive and HIV positive results
