The number of Americans who have died from alcohol-related problems annually more than doubled between 1999 and 2017, a new study found, and that’s likely an undercount, the researchers said.

The study was published Wednesday in the journal Alcoholism: Clinical and Experimental Research.

Looking at data from death certificates from 1999 to 2017, researchers from the National Institute on Alcohol Abuse and Alcoholism determined that the number of alcohol-related deaths increased 50.9% from 16.9 to 25.5 per 100,000. Specifically, they counted 35,914 deaths in 1999 and 72,558 by 2017. That’s a loss of nearly 1 million Americans in that time period. In 2017 alone, 2.6% of about 2.8 million deaths in the US were alcohol related.

About half of these deaths are from liver disease or an overdose from alcohol or alcohol mixed with other drugs. Men died at a higher rate than women, but the largest annual increase in deaths was among non-Hispanic white women. Rates of deaths also increased more for people between the ages of 55 and 64. Rates of death were higher among non-Hispanic American Indians and Alaska natives.

Researchers think this number of deaths is an undercount, because while death certificates are the best way to track deaths in the US, the certificates often fail to capture the role alcohol plays in a death. Past studies have shown that only about one in six drunk driving deaths are actually reported as alcohol-related.

Americans are drinking more. Per capita consumption is up about 8% since the turn of this century and binge drinking numbers increased about 7.7%. About 70% of the adult population said they drank in 2017, averaging a little over two drinks a day. By US standards, that would put a good number of adults in the “heavy drinker” category.

Earlier research referenced in the study also showed a “significant” increase in alcohol-related injuries. Between 2006 and 2014, the rate of people admitted to the ER due to alcohol increased 47.3% among people older than age 12. Alcohol-related hospitalizations increased 51.4% between 2000 and 2015.

Dr. Elliot Tapper, who has used the same data working on similar studies that show similar results, said the new research is strong.

“When multiple researchers come to the same conclusion using different methods, I can tell you for certain these results are valid,” said Tapper, an assistant professor at the University of Michigan whose area of practice focuses on cirrhosis and hepatic encephalopathy.

Tapper said he’s thought a lot over the years about why there are so many more alcohol-related deaths and he attributes it to three factors.

First, he said that the increased prevalence of obesity, metabolic syndrome and diabetes make an increase in alcohol consumption much more harmful.
