Alcohol misuse and functional impairment in the UK Armed Forces: a population-based study

Area of Science:

• Military health
• Occupational health
• Addiction medicine

Background:

• Alcohol misuse is a significant concern within military populations.
• Understanding the relationship between alcohol use and functional impairment is crucial for military readiness and personnel well-being.
• Psychiatric comorbidity may influence the association between alcohol misuse and impairment.

Purpose of the Study:

• To investigate the association between alcohol misuse and functional impairment in the UK Armed Forces.
• To determine if psychiatric comorbidity mediates the relationship between alcohol misuse and functional impairment.

Main Methods:

• A large cross-sectional study involving 8585 UK Armed Forces personnel.
• Data collected via questionnaire in 2005.
• Alcohol misuse assessed using the Alcohol Use Disorders Identification Test (AUDIT); functional impairment measured using the Short Form Questionnaire-36 (SF-36).

Main Results:

• An AUDIT score of 20 or higher was consistently associated with functional impairment (ORs 1.8-3.7).
• Alcohol dependence and alcohol-related harm were also linked to impairment, while binge drinking was not.
• Approximately half of individuals with AUDIT scores >= 20 reported psychological comorbidities.

Conclusions:

• Functional impairment in the military is primarily associated with significant alcohol misuse (AUDIT score >= 20), alcohol dependence, or alcohol-related harm.
• Individual-focused interventions should target these specific groups.
• Public health strategies for alcohol misuse can be broadly applied and enhanced for the entire military population.
