Epidemiological trends in drinking by age and gender: providing normative feedback to adults.
OBJECTIVE
The purpose of this research was to evaluate drinking rates as a function of age and gender and to disseminate current estimates of U.S. population drinking norms based on age and gender.


METHODS
Participants included 42,706 men and women 18 years and older who provided information about their drinking from the National Epidemiologic Survey on Alcohol and Related Conditions [National Alcohol Survey on Alcohol and Related Conditions (NESARC, 2001) dataset collected between 2001 and 2002 from a representative, non-institutionalized sample.


RESULTS
Results revealed greater frequency and typical quantity of alcohol consumption among men versus women. Age differences in drinking frequency suggests a sharp increase with legal drinking age followed by a period of reduced frequency, in turn followed by gradual increase up to retirement age. Age differences in typical drinking quantity suggest a sharp increase with legal drinking age followed by a gradual linear decline in number of drinks per occasion. Age differences in typical quantity were more pronounced among men.


CONCLUSIONS
Analyses provide epidemiological trends in drinking rates by age and gender, and emphasize the importance of within group differences when examining drinking rates. Discussion focuses on explaining how to incorporate norms information in prevention and treatment.
