Drug Overdose Deaths in Mexican-Heritage Arizonans: An Examination of Mortality Rates, Demographics, Drugs Involved,...

This study examined drug overdose deaths in Mexican-heritage Arizonans, with the goal of informing tailored overdose prevention programs for this community.

We analyzed death certificate data (from the Arizona Department of Health Services) for drug overdose deaths among Arizona residents from 2018-2022. We compared deaths in US-born and foreign-born Mexican-heritage Arizonans and, as a frame of reference, Non-Hispanic (NH) White Arizonans. We compared demographics, circumstances of death, and mortality rates, using descriptive statistics, multinomial logistic regression models, and age-standardized mortality rates and ratios.

The age-standardized drug overdose mortality rate (per 100,000) was lower in the overall Mexican-heritage population (28.0) than in the NH White population (35.9). Nonetheless, the rate in the US-born Mexican-heritage male subgroup (59.5) was higher than in US-born NH White males (49.9) or any other subgroup examined. Synthetic opioids such as fentanyl were involved in higher proportions of deaths among US-born (64.6%) and foreign-born (65.1%) Mexican-heritage Arizonans than among NH White Arizonans (48.5%). In multinomial regression models, the risk of a medical place of death, relative to death at home, was significantly higher in the foreign-born (adjusted Relative Risk Ratio [aRRR] 1.82; 95% Confidence Interval [CI], 1.38-2.42) and US-born (aRRR 1.85; 95% CI, 1.62-2.11) Mexican-heritage groups than the NH White group, adjusting for age, sex, marital status, county of residence, overdose intent, and drugs involved.

Findings highlight disparate rates of overdose mortality in US-born Mexican-heritage Arizona men, also underscoring racial/ethnic/nativity-based differences in overdose circumstances and decedent characteristics.
