Diabetes and tuberculosis, US National Health Interview Survey, 2000-2005.

Blacks and Hispanics are disproportionately affected by diabetes, which may confound ethnic association with tuberculosis (TB). We analyzed 2000-2005 National Health Interview Survey data. We present adjusted odds ratios (aORs) and 99% confidence intervals (CIs) for the association of diabetes with history of TB disease, controlling for race/ethnicity and age. Diabetics had an aOR of 1.4 (99%CI 1.0-2.0) for history of TB, controlling for being foreign-born non-Hispanic (aOR 2.2, 99%CI 1.6-3.2), US-born Hispanic (aOR 2.1, 99%CI 1.4-3.2), age ≥65 years (aOR 2.0, 99%CI 1.5-2.6), and being Black (aOR 1.6, 99%CI 1.1-2.4). After controlling for race/ethnicity, self-identified diabetics had an increased aOR for history of TB.
