Chronicity of drinking problems among men: a longitudinal study.

Analyses demonstrate that the chronicity of alcohol problems among men is a function of age; the probable chronicity over time is greater among older than among younger men. Alcohol problems among older men show greater interrelationships; remission is higher among younger men. The data have implications for estimates of the prevalence of alcoholism in the U.S. population. If the percentage of problem drinkers in the general population is used, actual prevalence will be overestimated. If the percentage of alcoholics in treatment is used, actual prevalence will be underestimated. The ability to identify men in the general population who are at risk for becoming alcoholics has implications for prevention of alcohol-related problems and the treatment of alcoholism.
