Associations among social determinants of health and opioid use disorder and overdose: An umbrella review

Abstract

Background and Objectives: In 2022, over 6 million individuals in the United States were affected by opioid use disorder (OUD), and more than 81,000 died from opioid-related overdoses. This umbrella review synthesized evidence on the associations between a broad range of social determinants of health (SDoH) and OUD/overdose. Methods: An umbrella review of meta-analyses and reviews on SDoH and OUD/overdose was conducted using PubMED, PsycINFO, Embase, and Web of Science. A total of 29 reviews were deemed appropriate for inclusion. Results: Adverse childhood experiences and unemployment were associated with OUD outcomes. In the United States, immigrant status was associated with a lower risk of OUD, though this risk increased in subsequent generations. Individuals who experienced intimate partner violence and sexual minority individuals showed high prevalence of OUD. For overdose, associations were found in unemployment, low income, high poverty, and justice system involvement. Significant increases in odds of overdose were noted among individuals experiencing homelessness, lacking private insurance, engaging in sex work for pay, or witnessing an overdose. Discussion and Conclusions: This study identified SDoH associated with OUD outcomes and overdose risk, with findings having implications from a public health perspective for clinical practice, public health policy, and research priorities. There is a need for meta-analyses to clarify the magnitude of SDoH influences on OUD/overdose, with the goal of informing targeted interventions to reduce opioid-related morbidity and mortality. Scientific Significance: The most comprehensive umbrella review to date on intersections among SDoH, OUD outcomes, and overdose risk.
