Importance: There are several apparent research gaps based on the intersectional sociodemographic dimensions of drug-related mortality disparities. Relatively marginal evidence exists on the potential roles of intersecting forms of race and sexual marginalization on the disparities across drug-related mortality.
Objective: To examine intersectional sex-specific White and Black racial disparities in drug poisoning mortality across states from 2010 to 2020.
Design, setting, and participants: This cross-sectional study used unintentional fatal drug poisoning mortality data from the Centers for Disease Control and Prevention's Web-Based Injury Statistics Query and Reporting System. Trends from 2010 through 2020 were analyzed by Black men, Black women, White men, and White women across states. One-sided Mann-Kendall trend analysis was used to examine statistically significant increasing or decreasing trends in age-adjusted mortality rates. Statistical analysis was performed from June to July 2024.
Exposures: White and Black groups intersecting with male and female sex.
Main outcomes and measures: Analysis of age-adjusted mortality rates, excess years of potential life lost (reference group: White men), years of potential life lost ratios (reference group: White men), and percentage change to highlight state differences.
Results: From a total sample of 518 724 unintentional fatal drug poisoning deaths (9.0% in Black men, 3.9% in Black women, 29.0% in White women, and 58.1% in White men), 11 820 781 years of potential life lost were recorded. Black men had the highest mean (SD) age-adjusted mortality rate (23.25 [22.65]), followed by White men (22.49 [14.32]), with lower rates for White women (11.71 [5.96]) and Black women (9.01 [8.04]) (P < .001). Compared with White men, both Black men (τ = 0.298, slope = 0.002, intercept = 0.381, P < .001) and Black women (τ = 0.157, slope = 0.0004, intercept = 0.271, P < .001) had worsening YPLL over time, while White women (τ = -0.146, slope = -0.0003, intercept = 0.5252, P < .001) showed improvement in their YPLL over time compared with White men. At the state level, there was a disproportionate burden of deaths due to drug poisonings, with Maryland showing the highest increase in mortality rates among Black men (485.4%), while decreases were observed for White women in states such as Alaska (-23.0%).
Conclusions and relevance: In this cross-sectional study of overdose deaths, disparities in overdose mortality were evident, with Black men and Black women experiencing a pronounced and increasing burden of mortality compared with their White counterparts. Addressing these disparities will require a multipronged approach targeting the social, physical, economic, and policy risk environments.
