A comparison of alcohol and commercial tobacco use in populous American Indian/Alaska Native states

Background: Modern research suggests that the racial influence on smoking and drinking behaviors may not be as prevalent as once thought. This study utilizes national survey data to compare binge drinking and commercial cigarette smoking behaviors between American Indians/Alaskan Natives (AI/AN) and non-Hispanic Whites in the five most populous AI/AN U.S. states. Methods: Data were analyzed from the Behavioral Risk Factor Surveillance System (BRFSS) from 2018 to 2022; White (n=79,405), AI/AN (n=11,007). Data analyses include frequency statistics, followed by two model evaluations comparing main effects of race/ethnicity and sex for both binge drinking and commercial cigarette smoking behaviors, and subgroup estimates of race/ethnicity by sex. An ANOVA was utilized to evaluate differences by race/ethnicity, sex, and race/ethnicity by sex subgroups by states. Results: Males were over twice as likely to engage in binge drinking, with no significant differences found between people identifying as AI/AN and White individuals. Both White and AI/AN males were twice as likely to engage in binge drinking, compared to their White female counterparts. AI/AN individuals were over twice as likely to engage in commercial cigarette smoking compared to their White counterparts. Conclusions: Results showed no significance differences in AI/AN versus White individuals in binge drinking (controlling for sex, age, and income), while there were significant differences by sex (controlling for race/ethnicity, age, and income). People identifying as AI/AN were significantly more likely to engage in commercial cigarette smoking compared to White individuals, signifying the importance of racial/ethnical and covariate considerations when establishing public health interventions.
