Health's influence on alcohol use-a longitudinal study of working adults in Sweden.

Moderate and poor health-related quality of life were associated with higher odds of heavy drinking compared to good HRQoL.

• Moderate HRQoL was associated with OR 1.26 (95% CI: 1.02–1.56) for heavy drinking.
• Poor HRQoL was associated with OR 1.39 (95% CI: 1.08–1.78) for heavy drinking.
• The pattern suggests a dose-response relationship between HRQoL and heavy drinking.
• Heavy drinking was defined as ≥21 units/week for men and ≥14 units/week for women.
• Analysis used baseline data from 7097 participants in the 2010 Stockholm Public Health Cohort with outcomes measured in 2014.

The combination of moderate HRQoL and low socioeconomic position was associated with increased odds of both heavy episodic drinking and heavy drinking, with evidence of additive interaction.

• Moderate HRQoL and low SEP was associated with OR 1.48 (95% CI: 1.02–2.15) for heavy episodic drinking (HED).
• Moderate HRQoL and low SEP was associated with OR 1.62 (95% CI: 1.01–2.60) for heavy drinking.
• Additive interaction was indicated by RERI: 0.79 and attributable proportion (AP): 0.49.
• Joint exposure analyses used good health and high SEP as the reference group.
• HED was defined as ≥5 units on a single occasion ≥2 times per month.

Associations between mental health and alcohol use outcomes were weaker and inconsistent compared to HRQoL associations.

• Good mental health combined with low SEP was associated with increased HED (OR: 1.35).
• Moderate mental health combined with intermediate SEP was associated with decreased HED (OR: 0.66).
• Mental health was categorized as good, moderate, or poor.
• The paper characterizes mental health findings as 'less consistent' than those for HRQoL.

The study examined whether socioeconomic position moderates the association between health and alcohol use among working adults in Sweden.

• Baseline data were from 7097 participants in the 2010 Stockholm Public Health Cohort.
• Exposures were HRQoL and mental health (categorized as good, moderate, or poor).
• Outcomes measured in 2014 included heavy episodic drinking and heavy drinking.
• Logistic regression estimated odds ratios with interaction assessed using RERI and attributable proportion.
• SEP was used both as a potential moderator and in joint exposure analyses with health measures.
