Moderate drinkers end up better thinkers

Moderate drinkers have been found to be better thinkers than heavy

drinkers and those who do not drink at all, according to the Australian

National University research. In a study of more than 7000 people aged

20-24, 40-44 and 60-64, participants were asked about their alcohol use,

and to perform a series of tests to measure cognition - verbal skills,

memory and speed of thinking.

ANU researchers Dr Kaarin Anstey and Dr Rodgers found that people

who had drunk moderate amounts of alcohol (14-28 standard drinks a week

for men and 7-14 standard drinks a week for women) performed

significantly better than those who were heavy drinkers (over 28 and 14

standard drinks for men and women respectively) and those who rarely or

never drank. This relationship was found in participants in their 20s,

40s and 60s.

In articles published online in the journal Addiction the researchers

outlined some of the reasons for the disparity.

“We found that people who did not drink were more likely to have poorer

mental and physical health, less education, and poorer lifestyles,” Dr

Anstey said. “However, these factors are not sufficient to fully explain

the results and further research is required to obtain a clearer picture

of exactly what this means for our thinking abilities.”

Dr Rodgers said: “This does not necessarily show that moderate alcohol

use is good for our brains - there may be other reasons that we haven’t

measured to explain the poor performance of non-drinkers.”

Their findings are the latest from the PATH Through Life project, a

20-year study of change in thinking and mood as people age, which was

initiated by the ANU Centre for Mental Health Research in 1999.

Other findings from the project have included:

· Strong associations between childhood adversity and adult depression.

Factors most strongly related to depression include: mother’s

depression, reports of neglectful upbringing, too much physical

punishment, having an unaffectionate father, and experiencing a lot of

family conflict.

· Bisexual people tended to suffer more from anxiety, depression and

suicidal tendency than homosexual or heterosexual study participants.

· Young Australian adults are the least likely to obtain GP care,

compared to other age groups - despite evidence of significant mental

health problems, such as tendencies towards suicide and substance abuse.

The study found that those who used GPs were most likely to be female,

to have been or be undertaking higher education and to be living with

children. Young adults were also identified as having poorer physical

health, more chronic diseases and higher levels of suicidal ideation

when regularly using marijuana.

· Elevated symptoms of depression, anxiety and negativity were related

to levels of tobacco consumption and marijuana use for both young men

and women.

Dr Anstey was recently awarded the The Margret M. Baltes Early

Investigator Award in Behavioral and Social Gerontology from the

Gerontology Society of America in recognition of her outstanding early

career contribution to gerontology.
