Heavy drinking
falls with age; Men and smokers slower
Previous studies have suggested that people reduce their
average alcohol consumption as they age. In the new study
the researchers sought to determine whether the percentage
of heavy drinkers—that is, men who have at least five drinks
in one sitting and women who have at least four drinks —
also reduced as they aged. This latest study was based on
data from 14,127 participants, aged 25 to 74, in the
National Health and Nutrition Examination Study, first
administered between 1971 and 1974, with three follow-ups
through 1992.
While the researchers noted that heavy drinking declined
with age, they found it fell more slowly among men compared
with women and among smokers compared with non-smokers. A
higher probability of heavy drinking was associated with
being unmarried, having less than a high school education,
an annual income below the median, and not living in the
Southeastern United States. Heavy drinking also declined
faster among those who got married or quit smoking between
follow ups.
IMPACT: Earlier studies have found that more educated people
and those with higher income drink more on average; yet,
this study showed that they are less likely to be heavy
drinkers. Regular moderate drinking--about one or two
glasses of wine per day, four or more days per week, is
probably beneficial to cardiovascular health, while heavy
drinking can be harmful, said Dr. Arun Karlamangla,
assistant professor of geriatrics at the David Geffen School
of Medicine at UCLA, and the study’s lead author. “Our study
suggests that more educated people and those with higher
income use alcohol regularly and moderately, while those
with less income and education are more likely to drink
heavily,” Karlamangla said. “The benefits of drinking will
be seen by the rich, the harm by the poor.” This is also the
first study to show that heavy drinking behavior can be
changed: Those who got married or quit smoking during the
study also reduced their heavy drinking.
AUTHORS: Others in addition to Karlamangla are Drs. David
Reuben, professor and chief of geriatrics; Gail Greendale,
professor of geriatrics; and Alison Moore, associate
professor of geriatrics; and Keifei Zhou, research assistant
in geriatrics. All are in the David Geffen School of
Medicine at UCLA.
