Alcohol-related Opioid Overdose Deaths in Minnesota Between 2011 and 2020: Trends by Sex

Abstract

Objectives: To characterize the overall trend and differences by sex in opioid overdose death (OOD) and alcohol-related opioid overdose deaths (AOOD) in Minnesota between 2011 and 2020 in relation to drug overdose deaths.

Methods: Using Minnesota death certificate data from 2011 to 2020, we identified OOD and AOOD among Minnesota residents aged 15 and older who died of a drug overdose death. We calculated significant differences in the annual proportion of OOD and AOOD and sex differences using Pearson x2 tests.

Results: Approximately 59% of all drug overdose deaths are attributed to opioids, and 18% of those deaths are alcohol-related. Significant increases in the proportion of OOD were found between 2019 and 2020 and a significant decrease between 2017 and 2018 for women only. No significant changes were found in the overall proportion of AOOD. Men had higher on average proportions of OOD and alcohol-related OOD.

Conclusions: Proportions of OOD in relation to overdose deaths increased between 2011 and 2020, with a precipitous increase between 2019 and 2020 while the proportion of AOOD remained relatively stable over the period. Alcohol remains a contributing factor in approximately 1 in 5 OODs in Minnesota. These results support the need for accessible, evidence-based prevention and treatment programs to prevent drug overdose.
