Heavy drinking occasions in Australia: do context and beverage choice differ from low-risk drinking occasions?

Area of Science:

• Alcohol consumption research
• Public health
• Behavioral science

Background:

• Recent heavy drinking occasions (RHDOs) and usual low-risk drinking occasions differ in patterns.
• Understanding these differences can inform public health interventions for heavy alcohol use.

Purpose of the Study:

• To compare drink choices and locations between recent heavy drinking occasions and usual low-risk occasions.
• To identify specific patterns associated with heavy alcohol consumption.

Main Methods:

• Population-based survey of 774 respondents reporting both RHDOs and usual low-risk occasions.
• Comparison of drink choice and drinking locations using confidence intervals.
• Defined RHDO as 8+ Australian standard drinks (ASD) for females, 11+ ASD for males; usual low-risk as <5 ASD.

Main Results:

• RHDOs were more likely to occur away from licensed premises (59%) compared to usual occasions.
• Pubs, bars, or nightclubs were more common for RHDOs (28%) than usual occasions (12%).
• Bottled spirits were the primary drink for RHDOs (33%) more often than for usual occasions (11%), while bottled wine was more common for usual occasions (33% vs. 20%).

Conclusions:

• Heavy drinking occasions occur frequently in private homes, not just licensed venues.
• The association of heavy drinking with beer may reflect general heavy drinker preferences rather than occasion-specific choices.
• Findings highlight the need for targeted interventions considering both location and drink type in heavy alcohol consumption.
