Abstract:

The National Health and Nutrition Examination Survey (NHANES) has tested for Mycobacterium tuberculosis infection three times: in 1971–1972, 1999–2000, and 2011–2012. Based on tuberculin skin test results, the estimated national prevalence of latent tuberculosis infection (LTBI) among adults was 11–18% in 1971–1972 but has remained less than or equal to 6% in subsequent NHANES cycles (1–4). A single 2-year NHANES cycle is designed to produce accurate and stable estimates for conditions with at least 10% prevalence in the noninstitutionalized civilian U.S. population (5–7), suggesting that NHANES might no longer be as nationally representative for LTBI as it is for more common health conditions. Approximately 30 counties were selected for each 2-year cycle (5). We wished to examine whether persons in selected counties might have been systematically more or less likely to have a positive tuberculin skin test result than their counterparts in the approximately 3,100 counties that were not selected for NHANES participation.
