Solitary drinking: a risk factor for alcohol-related problems?

Area of Science:

• Public Health
• Epidemiology
• Addiction Research

Background:

• Solitary drinking is prevalent in the general population.
• Understanding the association between solitary drinking and alcohol-related problems is crucial for public health interventions.
• Previous research has yielded mixed results on the risks associated with drinking alone.

Purpose of the Study:

• To investigate whether solitary drinking is a risk factor for alcohol-related problems.
• To examine different indicators of solitary drinking behavior.
• To identify specific patterns of solitary drinking associated with negative outcomes.

Main Methods:

• Data from a general population telephone survey of 2015 drinkers in Montréal, Canada.
• Three indicators of solitary drinking were assessed: drinking alone, frequency of solitary drinking, and consuming five or more drinks alone.
• Alcohol-related problems were measured using seven binary items covering social, health, work, and personal well-being domains.

Main Results:

• 31% of respondents reported drinking alone, with 27% doing so weekly and 17% consuming five or more drinks alone at least once.
• Univariate analysis showed positive associations between alcohol-related problems and both solitary drinking and heavy solitary drinking.
• Only heavy solitary drinking (five or more drinks alone) remained a significant predictor in logistic regression models controlling for confounders.

Conclusions:

• Solitary drinking per se is not a significant risk factor for alcohol-related problems.
• The risk is associated with the quantity of alcohol consumed while drinking alone, specifically consuming five or more drinks.
• Public health messaging should focus on heavy drinking occasions, regardless of whether they occur alone or in company.
