Alcohol Use Associated With Gambling Harm in a Population Representative Australian Sample

Area of Science:

• Public Health
• Behavioral Science
• Addiction Research

Background:

• Gambling and alcohol use are prevalent public health issues.
• Understanding the interplay between alcohol consumption and gambling behavior is crucial for harm reduction strategies.
• Previous research suggests potential links between these behaviors and adverse outcomes.

Purpose of the Study:

• To investigate the association between alcohol use while gambling and gambling harm in Victoria, Australia.
• To determine if heavy episodic drinking (HED) independently predicts gambling harm.
• To explore whether combined alcohol use behaviors exacerbate gambling-related harm, particularly in economically disadvantaged populations.

Main Methods:

• Utilized data from the 2023 Victorian Population Gambling and Health Study (N=3114).
• Employed regression analyses to assess the predictive value of drinking while gambling and HED on gambling harm.
• Measured gambling harm using the Short Gambling Harm Screen.

Main Results:

• Alcohol consumption while gambling was significantly associated with increased gambling harm (OR=2.58) and a higher number of harms (IRR=2.57).
• Heavy episodic drinking (HED) was associated with harm in initial analyses but not independently after controlling for other variables.
• The combination of HED and drinking while gambling showed a synergistic effect, significantly increasing gambling harm.

Conclusions:

• Drinking alcohol while gambling is a significant risk factor for gambling harm.
• Combined alcohol use behaviors, particularly HED with concurrent gambling, elevate risk substantially.
• Findings support interventions aimed at restricting alcohol availability in gambling venues to reduce harm.
