NHANES data show hepatitis B infection prevalence in US adults by race and origin

This observational analysis used data from the National Health and Nutrition Examination Survey (NHANES) to examine the prevalence of past or present hepatitis B virus infection among US adults aged 18 years and older. The study stratified results by race and Hispanic origin, though the specific sample size, follow-up duration, and detailed methodology were not reported.

No specific prevalence rates, absolute numbers, effect sizes, or confidence intervals were reported for the primary outcome of hepatitis B infection prevalence. The direction of any differences between demographic groups and statistical significance measures were also not provided in the available data.

Safety and tolerability data were not reported, as this was a prevalence study rather than an interventional trial. Key limitations include the observational nature of the data, which prevents causal inference, and the absence of reported methodological details such as sample size and statistical measures.

The practice relevance of these findings is limited to providing descriptive epidemiological context about hepatitis B infection patterns in the US adult population. Clinicians should interpret these findings cautiously as preliminary descriptive data that require confirmation with complete statistical reporting and peer-reviewed publication.
