Abstract

Abstract: Studies indicate an inverse association between moderate alcohol consumption and chronic inflammatory diseases; however, the association between alcohol consumption and chronic obstructive pulmonary disease (COPD) incidence has not been widely studied. We investigated the associations of total alcohol consumption and intake of specific alcoholic beverages with risk of COPD in a population-based prospective cohort study, the Cohort of Swedish Men ( n = 44, 254). Alcohol consumption was assessed with a self-administered questionnaire in 1997. During follow-up (1998–2014), 2, 177 COPD cases were ascertained. Moderate alcohol consumption was associated with the lowest risk of COPD. A J-shaped association was observed for ethanol consumption ( P for nonlinearity = 0.003) and beer consumption ( P for nonlinearity < 0.001); for wine consumption, a U-shaped association was observed ( P for nonlinearity < 0.001). Defining a "standard drink" as 12 g of ethanol, the multivariable-adjusted hazard ratios were 0.77 (95% confidence interval (CI): 0.66, 0.90) and 0.92 (95% CI: 0.81, 1.05) for beer consumption of 4.1–6.0 and >6.0 standard drinks/week (SDW) versus <1.0 SDW, respectively; 0.80 (95% CI: 0.69, 0.93) and 1.00 (95% CI: 0.83, 1.21) for wine consumption of 2.0–4.0 and >4.0 SDW versus <1.0 SDW, respectively; and 1.10 (95% CI: 0.98, 1.24) and 1.20 (95% CI: 0.99, 1.44) for liquor consumption of 2.0–4.0 and >4.0 SDW versus <1.0 SDW, respectively. In conclusion, our findings suggest that moderate beer and wine consumption, but not liquor consumption, may decrease risk of COPD. Additional studies are needed to confirm these associations.
