Intersectionality and the Association Between State-Level Structural Racism, Binge Alcohol Consumption, and Smoking Status Among Black Americans.

Background: Structural racism is associated with alcohol and tobacco use among Black Americans. There is a need to understand how this relationship differs within varying groups of Black Americans. This study assessed the moderating roles of age, gender, and income in the association between structural racism and binge alcohol consumption and tobacco smoking status among Black Americans.

Methods: A state-level index of structural racism was merged with data from a national probability sample of 1946 Black Americans. Hierarchical linear and logistic regression models tested associations between structural racism (measured by residential segregation, and economic, incarceration, and educational inequities) and binge alcohol use and smoking status among Black Americans by stratified by age, gender, and income. Moderating effects of age, gender, and income were tested using slope estimate comparisons.

Results: Results indicated statistically significant positive associations between incarceration disparities and binge drinking and smoking status among Black Americans below age 65. An inverse association was detected between education disparities and smoking status among Black Americans below age 65 and among higher-income Black Americans. Age, gender, and income were not significant moderators of these associations.

Conclusions: Age, gender, and income do not moderate the association between state-level structural racism and binge alcohol or tobacco use behaviors among the current sample of Black Americans.

Impact: Addressing structural racism may have implications for reducing participation in binge drinking and tobacco use behaviors among Black Americans, regardless of their age, gender, or income. This has implications for healthy equity and cancer prevention and control.
