Abstract
The aim of this study was to quantify the association between alcohol consumption and incidence of pneumonia and to examine possible pathways. This was done by a systematic review and meta-analyses on the dose-response relationship between alcohol consumption or alcohol-use disorders and the incidence of community-acquired pneumonia (CAP). The relative risk (RR) of CAP increased monotonically with increasing alcohol consumption. Individuals consuming 24, 60, and 120 g of pure alcohol daily demonstrated RRs for incident CAP of 112 (95% CI 102-123), 133 (95% CI 106-167) and 176 (95% CI 113-277), respectively, relative to non-drinkers. Clinically defined alcohol-use disorders were associated with an eightfold increased risk of CAP (RR 822, 95% CI 485-1395). In conclusion, alcohol was found to be a risk factor for pneumonia with a clear statistical association, and a monotonic dose-response relationship.
