PurposeHepatocellular carcinoma (HCC) incidence rates continue to increase in the United States. Geographic variation in rates suggests a potential contribution of area-based factors, such as neighborhood socioeconomic deprivation, retail alcohol availability, and access to health care.MethodsUsing the National Institutes of Health-American Association of Retired Persons Diet and Health Study, we prospectively examined area socioeconomic variations in HCC incidence (n = 434 cases) and chronic liver disease (CLD) mortality (n = 805 deaths) and assessed contribution of alcohol outlet density, health care infrastructure, diabetes, obesity, and health behaviors. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated from hierarchical Cox regression models.ResultsArea socioeconomic deprivation was associated with increased risk of HCC incidence and CLD mortality (HR, 1.48; 95% CI, 1.03–2.14 and HR, 2.36; 95% CI, 1.79–3.11, respectively) after accounting for age, sex, and race. After additionally accounting for educational attainment and health risk factors, associations for HCC incidence were no longer significant; associations for CLD mortality remained significant (HR, 1.78; 95% CI, 1.34–2.36). Socioeconomic status differences in alcohol outlet density and health behaviors explained the largest proportion of socioeconomic status-CLD mortality association, 10% and 29%, respectively. No associations with health care infrastructure were observed.ConclusionsOur results suggest a greater effect of area-based factors for CLD than HCC. Personal risk factors accounted for the largest proportion of variance for HCC but not for CLD mortality.
