A new study published in JAMA Psychiatry has found that sports gambling frequency and alcohol-related problems are strongly associated over time, reinforcing concerns about the potential health risks of concurrent gambling and drinking behaviors.

The study, funded by the International Center for Responsible Gaming (ICRG), analyzed data from over 4300 U.S. adults over two years. Researchers found that while alcohol-related problems slightly decreased over time, fluctuations in sports gambling frequency were closely tied to changes in alcohol-related harms. These findings suggest that individuals who engage in both activities may be at heightened risk of developing problematic drinking behaviors.

“These results emphasize the need for screening and intervention strategies targeting sports gamblers who also drink. It is quite likely that these behaviors are interacting in such a way that may increase the risks associated with both. Given the increasing accessibility of sports gambling in the U.S., understanding the health implications of these behaviors is critical,” said lead author Dr. Joshua B. Grubbs of the University of New Mexico.

The ICRG, the largest independent funder of gambling research in the US, has supported multiple studies aimed at understanding the risks associated with sports wagering. Dr. Grubbs’ latest research builds on his extensive body of work, which has resulted in 12 peer-reviewed publications examining gambling behaviors, addiction risks, and responsible gambling strategies. Supported by ICRG funding, his studies have significantly contributed to the understanding of these critical issues.

Among prior ICRG-supported findings:

• Sports bettors are at a higher risk for addiction than other gambling groups, with a strong connection to binge drinking. (JAMA Network Open, 2024)

• Impulsivity is a key predictor of high-risk gambling behaviors, underscoring the need for targeted intervention strategies. (Addictive Behaviors, 2024)

• Responsible gambling strategies must be tailored to different types of sports betting, as not all forms carry the same level of risk. (Journal of Gambling Studies, 2024)

• Marginalized communities face unique gambling challenges, requiring culturally sensitive harm-reduction strategies. (Addictive Behaviors, 2023)

“As sports gambling continues to expand, research like this is essential for understanding the broader public health implications. ICRG remains committed to funding rigorous, independent studies that contribute to evidence-based solutions for responsible gambling,” said Art Paikowsky, President of ICRG.
