Abstract
OBJECTIVES: We sought to assess the performance of self-reported vaccination with hepatitis B vaccine (HepB) compared with serological status for hepatitis B markers in the general US civilian population. METHODS: Using 1999 through 2008 National Health and Nutrition Examination Survey data, we calculated 3 measures of agreement between self-reported HepB vaccination status and serological status: percent concordance, and positive (PPV) and negative predictive values (NPV) of self-report. Logistic regression was used to identify factors associated with agreement between self-report and serological status. RESULTS: Overall agreement was 83% (95% CI = 82.3, 83.7), NPV of self-report was high (0.95; 95% CI = 0.93, 0.95) and PPV was low (0.53; 95% CI = 0.51, 0.54). Birth year relative to the 1991 recommendation for universal infant HepB vaccination had a strong association with agreement, however, the association was positive for those who reported receiving at least 3 doses and negative for those who reported receiving no doses. CONCLUSIONS: Although the low PPV in our study could be attributable in part to waning of vaccine-induced anti-HBs over time, national adult HepB vaccination coverage may be lower than previously estimated because national estimates usually depend on self-report of vaccine receipt.
