Cognitive function in drinkers compared to abstainers in the New Mexico elder health survey.
BACKGROUND
Recent epidemiological studies have shown that individuals who ingest alcohol regularly have a higher level of cognitive function and are less likely to develop dementia than those who abstain. The purpose of this study was to compare nine measures of cognitive function in drinkers compared to abstainers.


METHODS
A cross-sectional community survey was conducted of 883 randomly selected Hispanic and non-Hispanic white men and women, age >or=65 years of age, undergoing a paid home interview and 4-hour interview/examination in a senior health clinic (The New Mexico Elder Health Survey). The interviews included questions on frequency and quantity of alcohol ingested.


RESULTS
Participants who consumed alcohol had significantly better mean scores on 7 of 9 cognitive function tests and less frequently had scores below selected "cut points" compared to those who abstained from all alcohol intake. Scoring used multivariate linear and logistic regression models adjusted for sex, ethnicity, age, level of education, and evidence of depression.


CONCLUSIONS
Participants in the New Mexico Elder Health Survey (nearly equal numbers of Hispanic and non-Hispanic white men and women) who consumed alcohol had better scores on their cognitive tests than did those participants who abstained.
