This week’s news about excessive college
drinking is another shocking example of statistical deception
by shameless activists manipulating a media panting for
sensationalism.
USA Today’s "College drinking kills
1,400 a year, study finds" was the typical headline.
The frenzy was sparked by the National
Institute on Alcohol Abuse and Alcoholism’s report, "A Call to
Action: Changing the Culture of Drinking at U.S. Colleges."
In addition to the alleged death toll, the
report’s other alarmist claims include: 500,000 college
students are injured while under the influence of alcohol;
600,000 are assaulted; 70,000 are the victims of sexual
assault; 400,000 had unsafe sex; 25 percent have academic
problems; and 150,000 have alcohol-related health problems or
tried to commit suicide.
If true, these figures would make college
worthy of a Surgeon General’s warning.
But none of these likely-to-be-immortalized
factoids resulted from an actual count. They’ve been produced
by statistical guesswork.
"A Call to Action" doesn’t present the
analysis behind these claims. It only references a new study
simultaneously published in the March 2002, Journal of
Studies on Alcohol. The study’s lead author is Ralph
Hingson of the Boston University School of Public Health.
As an example of how goofy Hingson’s
numbers are, here’s how he calculated the headline-grabbing
estimate of 1,400 deaths.
There are about 25.5 million 18- to
24-year-olds living in the U.S., according to U.S. Census
data. Thirty-one percent of this age group are enrolled as
full or part-time students in two-or four-year colleges.
The number of alcohol-related motor vehicle
crash deaths among 18-24 years olds during 1998 is 3,674; 31
percent of this figure is 1,138.
Similarly applying the 31 percent factor to
the 991 alcohol-related, non-traffic deaths among 18- to
24-year-olds in 1998 results in an additional 307 deaths.
Adding the 307 and 1,138 figures equals the
alleged 1,445 alcohol-related deaths annually among college
students.
But Hingson relies on a key, but
unsupported assumption. It does not automatically follow that
college students constitute 31 percent of alcohol deaths
simply because 31 percent of 18- to 24-year-olds are college
students.
The simplistic reasoning is equivalent to
assuming that because women constitute about half the
population, they commit half of all crime. In fact, men commit
more than 75 percent of crime.
The definition of what constitutes an
"alcohol-related" death is another problem.
The National Highway Traffic Safety
Administration defines a fatal traffic crash as being
alcohol-related if either a driver or a pedestrian had a blood
alcohol concentration (BAC) of 0.01 grams per deciliter
(g/dl).
But 0.10 g/dl is the traditional level at
which persons are considered to be intoxicated. Just because a
person involved in a fatal accident has a measurable BAC
doesn’t mean that the alcohol caused or contributed to the
accident.
Even accepting Hingson’s results at face
value, his study is still silly.
There isn't a statistically-meaningful
difference in rates of alcohol-related problems between
college students and non-college students.
Hingson estimates, for example, that 41
percent of college students binge on occasion as compared to
36.5 percent of non-college students. But the relative
difference between the two estimates (14 percent) is too small
to be reliably detected in his crude data and analysis.
Also, if college students have alcohol
problems in proportion to their presence in the age group, why
crackdown only on college students? Are the other 69 percent
of 18- to 24-year olds not worthy of attention?
Why is Hingson playing fast and loose with
the data?
He’s on the board of directors of Mothers
Against Drunk Driving (MADD).
Although MADD began in 1980 with the
laudable goal of reducing drunk-driving fatalities, it has
strayed beyond its original mission. "If truth-in-advertising
laws applied to Mothers Against Drunk Driving, its name would
be changed to Mothers Against All Drinking of Any Kind," says
the Center for Consumer Freedom.
MADD’s crusade has turned into a
prohibitionist movement. Focusing on college kids and
pressuring universities seems to be the new tactic to
implement its misguided goal.
Mark Goldman, co-chair of the NIAAA task
force that produced "A Call to Action" told the Los Angeles
Times, "Our society has always dealt with [college
drinking] with a wink and a nod, as a rite of passage. But the
statistics that Ralph Hingson has put together are stunning to
all of us, even the most seasoned researchers."
This scam must be very intoxicating. How
can "seasoned researchers" fall for such obviously flawed
analysis? Will they also be using the movie Animal
House as evidence of excessive college drinking?
There is no question that some alcohol
abuse occurs among college students as it does among all 18-
to 24-year-olds. However, this is hardly news or an excuse for
junk science.
