Alcohol consumption and all-cause mortality

This study examined the association between alcohol consumption and mortality risk in United States adults, using data from the National Health Interview Surveys of 333,247 participants ≥18 years of age and categorizing participants according to self-reported alcohol consumption patterns. Median follow-up was 8.2 years. Compared with lifetime abstainers, individuals who were light or moderate consumers were at a reduced risk of all-cause mortality, but that risk increased significantly with heavy alcohol consumption, as seen in this J-shaped curve. Dashed lines: 95% CI.
