Researchers are reporting changes in alcohol consumption across the United States, with younger adults showing some of the largest declines in drinking. However, Iowa continues to report elevated rates of binge drinking and alcohol-related health concerns.
University of New Mexico psychology professor Katie Witkiewitz says research indicates that younger adults are reducing their alcohol consumption at a greater rate than other age groups. Younger adults have historically reported higher rates of drinking and alcohol-related problems.
According to a 2020 report from the Iowa Department of Health and Human Services, 57 percent of Iowa adults reported consuming at least one alcoholic beverage during the previous month, compared to 61 percent a decade earlier. The national average was reported at 53 percent.
Researchers are also examining the growing interest in alcohol-free lifestyles, including participation in movements such as Sober October. These efforts encourage individuals to temporarily abstain from alcohol or reconsider their drinking habits.
Witkiewitz says some individuals who reduce their alcohol consumption report changes in sleep patterns and energy levels.
Despite reported declines in alcohol consumption, Iowa continues to face alcohol-related public health concerns.
According to information from Iowa health officials, the state ranked fourth nationally in alcohol-related cancer incidence and had the highest rate in the Midwest. In 2019, Iowa’s alcohol-related cancer rate was reported to be nearly 10 percent higher than the national average.
Alcohol also remains present in various social settings, including sporting events, restaurants and community gatherings. Researchers continue to examine how advertising and social environments influence drinking habits.
An Iowa state report estimated that excessive alcohol consumption cost the state nearly $2 billion in 2010. Those costs included lost workplace productivity, health care expenses and criminal justice expenditures.
A 2025 report from Find Recovery ranked Iowa first nationally for binge drinking, reporting a rate of 22.5 percent. The report also indicated that the state’s binge-drinking rate had declined slightly over the previous decade.
The findings reflect different measurements of alcohol consumption and its effects. While some research indicates changes in drinking patterns, state and national reports continue to document alcohol-related health and economic concerns.
