Abstract
Background
Current US hepatitis B mortality rates remain three times higher than the national target. Mortality reduction will depend on addressing hepatitis B disparities influenced by social determinants of health.
Objectives
This study aims to describe characteristics of hepatitis B–listed decedents, which included US birthplace status and county social vulnerability attributes and quantify premature mortality.
Methods
We conducted a cross-sectional analysis of 17,483 hepatitis B–listed decedents using the 2010–2019 US Multiple-Cause-of-Death data merged with the county-level Social Vulnerability Index (SVI). Outcomes included the distribution of decedents according to US birthplace status and residence in higher versus lower death burden counties by sociodemographic characteristics, years of potential life lost (YPLL), and SVI quartiles.
Results
Most hepatitis B–listed decedents were US-born, male, and born during 1945–1965. Median YPLL was 17.2; 90.0% died prematurely. US-born decedents were more frequently White, non-college graduates, unmarried, and had resided in a county with < 500,000 people; non-US-born decedents were more frequently Asian/Pacific Islander, college graduates, married, and had resided in a county with ≥ 1 million people. Higher death burden (≥ 20) counties were principally located in coastal states. US-born decedents more frequently resided in counties in the highest SVI quartile for “Household Characteristics” and “Uninsured,” whereas non-US-born decedents more frequently resided in counties in the highest SVI quartile for “Racial/Ethnic Minority Status” and “Housing Type/Transportation.”
Conclusion
This analysis found substantial premature hepatitis B mortality and residence in counties ranked high in social vulnerability. Successful interventions should be tailored to disproportionately affected populations and the social vulnerability features of their geographic areas.

Data Availability
Restricted-use US Multiple Cause of Death data were acquired through an approved project determination to the CDC National Center for Health Statistics to obtain information on state and county of decedent residence and birth. The public-use CDC Social Vulnerability Index data were obtained from the CDC’s Agency for Toxic Substances and Disease Registry website.
