Cirrhosis mortality and per capita consumption of distilled spirits, United States, 1949-1994: trend analysis.

OBJECTIVE To describe, evaluate, and suggest interpretations for an observed aggregate-level relation between trends in mortality from cirrhosis and per capita consumption of distilled spirits in the United States. DESIGN Trend analysis using data on US cirrhosis mortality and per capita alcohol consumption. RESULTS There is a consistent long-term trend relation between mortality from cirrhosis and per capita consumption of distilled spirits in the United States from 1949 to 1994. Two instances of comparatively sharp drops in the consumption of spirits in the 1940s generated mixed results in predicting changes in cirrhosis mortality. CONCLUSIONS An aggregate-level relation between trends in long-term cirrhosis mortality and the consumption of spirits falls considerably short of establishing a direct causal link between the two for individuals. Moreover, two sharp drops in the consumption of spirits generated only mixed results with respect to the short-term trend in cirrhosis. Nevertheless, the observed relation between the consumption of spirits and cirrhosis mortality merits further investigation.
