Alcohol-Related Deaths During the COVID-19 Pandemic
Research letter
Abstract
Background
Research suggests that alcohol consumption and related harms increased during the first year of the COVID-19 pandemic. Studies reported increases in alcohol use to cope with stress, transplants for alcohol-associated liver disease, and emergency department visits for alcohol withdrawal.
The researchers examined mortality data to assess whether alcohol-related deaths increased during the pandemic as well.
Methods
US mortality data from the National Center for Health Statistics were used to compare numbers and rates of alcohol-related and all-cause deaths among all individuals 16 years or older in 2019 and 2020. Provisional data for the first half of 2021 (as of January 2022) were obtained from the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research. The National Institutes of Health Office of Intramural Research deemed the project exempt from institutional review board oversight.
Death certificates list an underlying cause and up to 20 multiple (contributing) causes. Deaths were identified as alcohol-related if an alcohol-induced cause was listed as an underlying or contributing cause (Supplement). Age-adjusted rates were calculated using the 2000 US Standard Population. For age groups, age-specific rates were presented instead. Comparisons between rates in 2019 and 2020 overall and by age group and sex were conducted with SAS, version 9.4 (TS Level 1M3) using 2-tailed z tests with an α level of .05.
Results
The number of deaths involving alcohol increased between 2019 and 2020, from 78,927 to 99,017.
This means that alcohol deaths increased by 25.5%.
The age-adjusted rate also increases from 27.3 to 34.4 per 100 000.
This is a relative change of 25.9%].
Comparatively, deaths from all causes had smaller relative increases in number (from 2,823,460 to 3,353,547 [18.8%]) and rate (from 938.3 to 1094.3 per 100 000 [16.6%]).
Alcohol-related deaths accounted for 2.8% of all deaths in 2019 and 3.0% in 2020.
Rates increased for all age groups, with the largest increases occurring for people aged 35 to 44 years (from 22.9 to 32.0 per 100 000 [39.7%]) and 25 to 34 years (from 11.8 to 16.1 per 100 000 [37.0%]). Increases in rates were similar for females (from 13.7 to 17.5 per 100 000 [27.3%]) and males (from 42.1 to 52.6 per 100 000 [25.1%]).
The number of deaths with an underlying cause of alcohol-associated liver diseases increased from 24,106 to 29,504 (22.4%) and the number of deaths with an underlying cause of alcohol-related mental and behavioral disorders increased from 11,261 to 15,211 (35.1%).
Opioid overdose deaths involving alcohol as a contributing cause increased from 8503 to 11 ,969 (40.8%). Deaths in which alcohol contributed to overdoses specifically on synthetic opioids other than methadone (eg, fentanyl) increased from 6302 to 10,032 (59.2%).
During 2020, a total of 2042 death certificates listed alcohol and COVID-19 as causes (1475 listed COVID-19 as the underlying cause, 323 listed alcohol as the underlying cause). As such, only a small proportion of the increase in alcohol-related deaths involved COVID-19 directly.
Discussion
The number and rate of alcohol-related deaths increased approximately 25% between 2019 and 2020, the first year of the COVID-19 pandemic. Rates increased prior to the pandemic, but less rapidly (2.2% mean annual percent change between 1999 and 2017).
The rate increase for alcohol-related deaths in 2020 outpaced the increase in all-cause mortality, which was 16.6%.
Previous reports suggest the number of opioid overdose deaths increased 38% in 2020, with a 55% increase in deaths involving synthetic opioids such as fentanyl. There were similar increases in the number of deaths in which alcohol contributed to overdoses of opioids (40.8%) and, specifically, synthetic opioids (59.2%).
Deaths involving alcohol reflect hidden tolls of the pandemic.
Increased alcohol use to cope with pandemic-related stressors, shifting alcohol policies, and disrupted treatment access are all possible contributing factors.
Whether alcohol-related deaths will decline as the pandemic wanes, and whether policy changes could help reduce such deaths, warrants consideration.
Study limitations include inaccurate death certificates, such as underreporting of alcohol involvement, and unclear causal relationships among listed causes of deaths. Provisional data are subject to change when more death certificates are processed.
