ABSTRACT.Objective: Integrating data from the National Highway Traffic Safety Administration,
the Centers for Disease Control and Prevention, national coroner studies, census
and college enrollment data for 18–24-year-olds, the National Household Survey on
Drug Abuse, and the Harvard College Alcohol Survey, we calculated the alcoholrelated
unintentional injury deaths and other health problems among college students
ages 18–24 in 1998 and 2001. Among college students ages 18–24 from 1998 to 2001,
alcohol-related unintentional injury deaths increased from nearly 1600 to more than
1700, an increase of 6% per college population. The proportion of 18–24-year-old college
students who reported driving under the influence of alcohol increased from 26.5%
to 31.4%, an increase from 2.3 million students to 2.8 million. During both years more
than 500,000 students were unintentionally injured because of drinking and more than
600,000 were hit/assaulted by another drinking student. Greater enforcement of the
legal drinking age of 21 and zero tolerance laws, increases in alcohol taxes, and wider
implementation of screening and counseling programs and comprehensive community
interventions can reduce college drinking and associated harm to students and others.
National surveys have focused attention on the heavy drinking patterns of many
college students. In 1993, 1997, and 1999, the Harvard School of Public Health
College Alcohol Surveys (CAS) monitored among college students heavy or binge
drinking, defined as five or more drinks in a single drinking session for males and
four or more for females (77–79). In 1999, of 14,138 full-time students randomly
selected at 128 4-year colleges and universities, 44% reported at least one heavy
drinking episode in the previous year, the same percentage as in 1993 (79). About
one fourth (23%) frequently drank in this manner (3 or more times in the past 2
weeks), up from 20% in 1993. Similarly, the national Monitoring the Future study
(36) reported 40% of 1440 full-time 2- and 4-year college students surveyed in
1999 consumed 5 or more drinks on a single occasion at least once in the previous
2 weeks, a greater proportion than found among same-age noncollege peers (35%)
and high school seniors (31%).
In 1998 the National Advisory Council of the National Institute on Alcohol
Abuse and Alcoholism (NIAAA), one of the Institutes of the National Institutes
of Health, created a task force to review the research on college drinking to advise
administrators and the NIAAA on implementing and evaluating college programs
and future research directions. This study resulted in a 2002 report:A Call to Action:
Changing the Culture of Drinking on U.S. College Campuses (57). Background
papers appeared in “College Drinking, What Is It and What to Do About It? A
Review of the State of the Science” in the Journal of Studies for Alcohol (23).
One of the 24 articles commissioned for this panel (30) estimated that in 1998
more than 1400 students ages 18–24 enrolled in 2- and 4-year colleges died from
alcohol-related injuries including motor vehicle crashes. Further, of the 8 million
college students in the United States more than 2 million drove under the influence
of alcohol and over 3 million rode with a drinking driver. More than 500,000 fulltime
4-year-college students were unintentionally injured under the influence of
alcohol, and more than 600,000 were hit or assaulted by and more than 70,000
experienced a date rape caused by another student who had been drinking.
morbidity and mortality among U.S. college students ages 18–24 changed from
1998 to 2001. We also outline interventions, identified by rigorous research in
the 2002 NIAAA report and the recent National Academy of Science Report to
Congress Preventing Under Age Drinking: A Collective Responsibility, to reduce
college drinking problems (52).
Methods: Calculating Changes in Alcohol-related Mortality
This review compares the number of alcohol-related traffic and other unintentional
injury deaths in 1998 and 2001 among 18–24-year-olds in the United States who
are full- or part-time college students attending either 2- or 4-year colleges. Information
was integrated from multiple data sets because the U.S. Department of
Transportation Fatality Analysis Reporting System (FARS): NHTSA (56) does
not routinely record whether persons who die in motor vehicle crashes are college
students. In addition, people who die from other types of unintentional injuries
are not systematically tested for blood alcohol concentrations (BACs). The data
sources consulted are described below.
First, the Centers for Disease Control and Prevention (CDC) annually records
the numbers and ages of unintentional injury deaths (5), but they do not record
whether these deaths are alcohol related. Second, a recent meta-analysis of 331
medical examiner studies (65) from 1975 to 1995 revealed that 84% of unintentional
nontraffic fatalities were tested for BACs. Of those tested, 38% had positive
BACs, and 31% had BACs of 0.10% or higher, exceeding legal limits for intoxication
nationwide (65). This analysis provides the best available estimates for
alcohol involvement in injury deaths (other than motor vehicle crash deaths), but it
does not provide information on annual changes in the proportions of those deaths
that are alcohol related.
Third, the National Highway Traffic Safety Administration’s (NHTSA) FARS
records all motor vehicle crash deaths in the United States (55, 56) and the proportion
that are alcohol related, defined as involving a driver or pedestrian with
a positive BAC. The ages of decedents are recorded, as are their blood alcohol
concentrations. Because BACs are not drawn on all motor vehicle crash deaths,
an imputational formula projects the likelihood of alcohol involvement in those
crashes for which test results are not available.
Fourth, the Department of Education’s National Center for Education Statistics
(53) reports the number of undergraduate college students in the United States. In
1998, of the 26,058,760 18–24-year-olds living in the United States (17), 8,670,000
(33%) were enrolled as full- or part-time students in either 2- or 4-year colleges:
24% (n = 6,106,000) in 4-year colleges and 10% (n = 2,564,000) in 2-year
colleges. Of students enrolled in 4-year colleges, 74% were ages 18–24, as were
60% of those enrolled in 2-year colleges. In 2001, of the 27,918,979 18–24-yearolds
living in the United States, 8,894,000 (32%) were enrolled as either fullor
part-time college students: 23% 6,381,000 (23%) in 4-year colleges and 9%
2,518,000 (9%) in 2-year colleges. Of students enrolled in 4-year colleges 74%
were age 18–24, as were 61% of those enrolled in 2-year colleges.
Fifth, the National Household Survey of Drug Abuse in 1999 and 2002 surveyed
18–24-year-olds regardless of whether they were college students (66, 67). In both
surveys, college students were more likely than same-age noncollege respondents
to report drinking five or more drinks on at least one occasion in the past month and
driving under the influence in the past year. On the basis of those survey results, we
projected that the proportions of traffic and other unintentional injury decedents
testing positive for alcohol would be as high among college 18–24-year-olds as
noncollege-year-olds same-age persons. Because college students comprised 33%
of the 18–24-year-old population in 1998 and 32% in 2001, we estimated that
in 1998 18–24-year-old college students accounted for 33% and in 2001 32% of
traffic and other unintentional injury deaths experienced by the 18–24-year-old
Calculation of other Alcohol-Related Risks
Two national surveys conducted in 1999 and 2002 (66, 67) asked students about
their experiences with alcohol in the previous year. Using their responses and data
on the numbers of college students in the United States during those years, we
estimated the annual numbers of college students ages 18–24 who drive under
the influence of alcohol, were injured because of drinking, and experienced other
The National Household Survey on Drug Abuse (NHSDA) (67) is the primary
source of statistical information on illegal drug use in the United States. Sponsored
by the Substance Abuse and Mental Health Services Administration (SAMHSA)
(66), computer-assisted interviews are conducted with a representative sample of
the United States: residents of households and noninstitutional group quarters (e.g.,
shelters, rooming houses, dormitories) and civilians living on military bases.
The 1999 and 2002 NHSDA used an independent multistage area probability
sample for each of the 50 states and the District of Columbia. Youth and young
adults were oversampled so that each state’s sample was approximately equally
distributed among people ages 12–17, 18–25, and 26 and older.
distributed among people ages 12–17, 18–25, and 26 and older.
In 1999, 169,166 addresses across the United States were screened, and 66,706
persons were interviewed within screened addresses. Weighted response rates for
households screened and interviewed were 89.6% and 68.6%, respectively. The
sample included 19,438 respondents ages 18–24, of whom 6930 (36%) were enrolled
in college, 5796 (30%) as full-time students and 1134 (6%) as part-time
In 2002, 68,126 persons were interviewed within the screened addresses.Weighted
response rates for households screened and persons interviewed were 91% and
79%. In the survey 20,478 respondents were ages 18–24, of whom 8041 (39%)
were enrolled in college.
Respondents were asked howoften they drank 5 or more alcoholic drinks on any
one occasion in the past 30 days. They were also asked, reflecting on the previous
12 months, Has your use of alcohol caused you to have any health problems?, Have
you driven a vehicle under the influence of alcohol only?, and Have you received
treatment or counseling for your use of alcohol?
The Harvard School of Public Health CAS began in 1993 (77) with a sample
of 140 colleges selected from a list of all accredited 4-year colleges provided by
the American Council on Education, using probability sampling proportionate to
the size of undergraduate enrollment at each institution. At each college, a random
sample of 225 undergraduates was drawn from the total enrollment of full-time
students. In 1999 (79), another survey was conducted with 128 of the original
140 colleges. The inability of 10 colleges in 1997 and 2 colleges in 1999 to provide
a random sample of students and their mailing addresses resulted in the attrition
of those schools. In 1999, 12,317 full-time students, ages 18–24 and having come
from 40 states, were surveyed; nearly half of these students lived in dormitories,
college housing, fraternities, or sororities (response rate 60%) (79).
In 2001, 215 full-time students ages 18–24 were randomly selected for the
survey from each of 119 colleges and universities that had been part of the 1999
sample, response rate 52% (80). Respondents were asked their frequency and usual
quantity of drinking, whether during the current school year they experienced
a variety of health and social problems because of their drinking, and whether
the drinking of other college students posed any of a series of social and health
problems for them.
Statistical Analyses of Surveys
For both surveys we present weighted results that consider their respective designs
and nonresponse. All statistical estimates of percentages for the survey data were
conducted using the SUDAAN statistical package to account for each survey’s
design (63). The SUDAAN package accounts for sampling weights in calculating
both estimates and standard errors, using first-order Taylor series approximations
to provide standard errors that approximately account for sampling design.
Using the information above, we identified the percentage of 2- and 4-year
college students ages 18–24 who responded affirmatively to the survey questions
regarding alcohol problems and then calculated 95% confidence intervals
for those responses. To estimate the numbers of 18–24-year-old college students
who experienced those problems, we then multiplied those percentages
and confidence intervals by the appropriate population count from the Department
of Education of students 18–24 years enrolled in 2- and 4-year colleges in
the United States. Data from the Department of Education are considered to be
true population totals; therefore, our confidence intervals reflect only the sampling
variability in the percentage estimates. We also made projections from the
CAS responses to the full-time 4-year college population using the same analytic
Percentages of responses with 95% confidence intervals were calculated from
survey data accounting for the sampling design. Changes in numbers of events
and rates of events per 100,000 population were described through relative risks,
and 95% confidence intervals were calculated using the Poisson model. These
percentages and confidence intervals are available on request.
Motor Vehicle Crash Deaths
The NHSDA surveys in both 1999 and 2002 revealed that in the year prior to
the survey, a significantly greater percentage of 18–24-year-old college students
compared with same-age noncollege respondents drank 5 or more drinks on a single
occasion in the past month (41.7% versus 36.5% in 1999 and 43.2% versus 39.8%
in 2002) and drove under the influence of alcohol in the previous year (26.5%
versus 19.8% in 1999 and 31.4% versus 23.7% in 2002). The percentage in both
groups of 18–24-year-olds who drank 5 or more drinks in the past 30 days did
not significantly increase from 1999 to 2002. However, the percentage of college
students who drove under the influence in the past year increased significantly
[RR = 1.18 (95% CI 1.13, 1.25)].
In 1998, in the United States, among persons ages 18–24, 3783 (51%) of 7452
taffic deaths were alcohol related. On the basis of a deliberately conservative
assumption that college students (33% of the U.S. population ages 18–24 in 1998)
experienced alcohol-related fatalities at the same rate as the entire 18–24-year-old
population, 1248 (33%) of the alcohol-related traffic deaths in that age groupwould
have been college students. (Note this figure is somewhat higher than reported by
Hingson et al. (30) because the Census Bureau revised its estimate of college
students in 1998 from 8 million to 8.67 million.)
In 2001, in the United States, among persons ages 18–24, 4216 (51%) of the
8242 traffic deaths were alcohol related. Assuming that college students (32%
of the U.S. population ages 18–24 in 2001) experienced alcohol-related fatalities
at the same rate as the entire 18–24-year-old population, 1349 (32%) of the
alcohol-related traffic deaths in that age group would have been college students
From 1998 to 2001 the U.S. population ages 18–24 increased 7%, whereas
alcohol-related traffic deaths increased 11%. Thus the increase in alcohol-related
traffic deaths per 18–24-year-old population was 4%. The U.S. college population
ages 18–24 increased 3%, but the number of alcohol-related traffic deaths
among 18–24-year-old students increased 8%. The 5% increase in the rate of
alcohol-related traffic deaths from 14.4 to 15.2 per 100,000 college students approached,
but did not reach, statistical significance [RR = 1.05 (95% CI 0.98,
Unintentional Nontraffic Deaths
In the NHSDA survey, 18–24-year-olds in college and not in college were equally
likely to report alcohol-related health problems (1.9% versus 2.0% in 1999 and
2.1% versus 2.3% in 2002). According to the CDC there were 10,052 unintentional
injury deaths among 18–24-year-olds in 1998 and 11,272 in 2001 (5). Subtracting
7444 traffic deaths in 1998 from the total unintentional injury deaths among 18–
24-year-olds that year and 8242 from the total in 2001 yielded 2608 nontraffic
injury unintentional deaths in 1998 and 3030 in 2001. If 38% were alcohol related,
as reported in national analyses of coroner studies (64), then 991 persons ages
18–24 in 1998 and 1151 in 2001 died from alcohol-related nontraffic injuries.
If 33% of those deaths were among college students in 1998 and 32% in 2001,
then 327 students in 1998 and 368 in 2001 died from alcohol-related nontraffic
From 1998 to 2001, the rate of these deaths showed a non-significant 10% increase
from 3.8 to 4.1 per 100,000 college students, RR = 1.10 (95% CI 0.95,
1.27). Among 18–24-year-old college students, deaths from all alcohol-related
unintentional injuries, including traffic and other unintentional injury deaths, increased
from 1575 in 1998 to 1717 in 2001, corresponding to an increase in the
rates of these deaths from 18.2 to 19.3 per 100,000 students, a 6% increase that
approached statistical significance (RR = 1.06, 95% CI 0.99, 1.14). From 1998
to 2001 the total population of persons ages 18–24, including college students and
others, increased 7%, and alcohol-related unintentional injury deaths increased
12% from 4771 to 5367, a significant 5% increase per population [RR = 1.05
(95% CI 1.01, 1.09)].
Heavy Episodic Drinking
From 1999 to 2002, the proportion of college students ages 18–24 who drank
5 or more drinks on an occasion in the previous 30 days increased from 41.7%
to 43.2%, a nonsignificant increase. The number of college students ages 18–24
who consumed at least 5 drinks on an occasion in the previous month increased
from 3,615,550 to 3,842,208, a nonsignificant 4% increase per college student
population. The increase in the proportion who reported a health problem related
to alcohol, from 1.9% to 2.1%, was also not significant. However, the proportion
of college students ages 18–24 who in the past year reported driving under the
influence of alcohol increased significantly from 26.5% to 31.4%, RR = 1.18%
(95% CI 1.13, 1.25); the proportion of students who were arrested for an alcoholrelated
offense or who were receiving treatment for an alcohol or drug problem
increased from 1.4% to 2.2%, RR=1.37 (95% CI 1.22, 2.01). The number of
students who drove under the influence of alcohol in the previous year increased
from 2,297,550 to 2,792,716, a highly significant 18% increase per college student
Other Alcohol-Related Health Problems
From 1998 to 2001 the number of full-time 4-year college students ages 18–
24 in the United States increased 4% from 5,496,000 to 5,709,000. Because the
proportion of students who in the CAS reported being hurt or injured or having
unprotected sex did not significantly change from 1999 to 2001, the projected
number of students with these experiences increased at rates similar to the proportional
population increase. In 2001, 599,000 (10.5%) were injured because of
drinking and 474,000 (8%) had unprotected sexual intercourse as a result of their
drinking. Although in 2001 slightly smaller proportions reported being assaulted
or hit by another drinking college student, more than 696,000 (12%) experienced
that problem in 2001, and 97,000 (2%) were alcohol-related sexual assault or date
Discussion: Estimates of the Magnitude
of College Drinking Problems
From 1998 to 2001 the nationwide number of alcohol-related deaths among 18–24-
year-olds rose at a rate that significantly exceeded that age group’s proportional
population increase. Whereas the population increased 7% from 26,058,760 to
27,918,979, alcohol-related unintentional injury deaths rose 12% from 4771 to
5367. Thus, alcohol-related deaths per population of 18–24-year-olds rose 5%
from 1998 to 2001.
From 1998 to 2001, among college students ages 18–24 the population increased
3% from 8,670,000 to 8,894,000, whereas unintentional alcohol-related injury
deaths increased 9% from 1575 to 1717. Thus, similar to the overall 18–24-yearold
group, among college students alcohol-related unintentional injury deaths per
population rose 6%, an increase that approached statistical significance. In 2001,
nearly 600,000 college students were injured because of drinking, and 696,000
were assaulted by another drinking college student.
Although the numbers are disturbingly high,webelieve our estimates of alcoholrelated
college deaths are conservative. First, we focused only on unintentional
injury deaths, not homicides and suicides, many of which are also alcohol related.
Second, the proportion of 18–24-year-olds who engage in heavy episodic drinking
and driving under the influence of alcohol is higher among persons that age who
are enrolled in college. Consequently, our projection that college and noncollege
18–24-year-olds experience traffic alcohol-related injury deaths at the same rate
per population in each group was intentionally conservative.
Third, the meta-analysis of coroner studies (65) did not provide age-specific
estimates of alcohol involvement in nontraffic unintentional injury deaths. We
estimated the proportion of nontraffic unintentional injury deaths was the same
among 18–24-year-old college students as among adults all ages, even though
persons 18–24 are known to drink more than other adults. A higher proportion
of traffic fatalities are alcohol related in the 18–24-year-old population (51%)
than among all age groups (38%). It is therefore possible, if not likely, that our
estimates of the number of unintentional alcohol-related nontraffic injury deaths
among 18–24-year-olds are also conservative.
Fourth, if respondents underreport illegal behaviors like driving under the influence
of alcohol, our estimate of the numbers of students who engage in those
behaviors may be low.
Fifth, response rates for the NHSDA and CAS were low. Thus, students may
under- or overrepresent problems associated with alcohol. In 1999 a short form
of the CAS was sent to nonresponding students, and there was no significant
difference in rates of previous year alcohol use for those answering the short survey
compared with the full questionnaire. Of note, the estimates of heavy episodic
drinking reported by college students in the NHSDA and the CAS are very similar
to those obtained by other major national surveys that include college students
e.g., the Monitoring the Future Survey (36, 37).
Sixth, this analysis focused only on college students ages 18–24. In 1998 only
74% of 4-year college students and 60% of students at 2- or 4-year colleges were
ages 18–24. In 2001, 74% of 4-year college students and 61% at 2-year colleges
were in that age group.We have calculated the overall numbers of college students
all ages who drink heavily and experience alcohol-related health problems. These
numbers are larger than those reported here and are available on request.
The magnitude of problems posed by excessive drinking among college students
should stimulate both improved measurement of these problems and efforts to
reduce them. We believe every unnatural death in the United States should be
tested for alcohol. The average cost of such testingwould be approximately $50 per
deceased person or an annual cost of $1.1 million if all injury deaths of those under
21 were tested or $7.2 million for 144,374 unintentional deaths, homicides, and
legal intervention and suicide deaths of all ages recorded in 2001. In comparison,
the National Academy of Sciences (52) reports $71.1 million are spent annually
to reduce underage drinking. Even though this review used cautious assumption to
estimate the numbers of alcohol-related deaths among college students and other
18–24-year-olds, direct systematic alcohol test results would be preferable. Also,
mortality data sets (e.g., the Department of Transportation’s FARSand CDC’sVital
Statistics Mortality File) should include occupation and student status categories
so that the absolute number of annual college student deaths can be tabulated.
Progress has been made over the past two decades to reduce alcohol-related
crash deaths. This process has occurred in part because a sufficiently high and
consistent level of fatally injured drivers in crashes are tested for alcohol that statistical
models based on crash factors, vehicle factors, and person factors have
been developed and used to estimate the annual numbers of alcohol-involved fatal
crashes in all states (40). The data on the numbers of alcohol-related fatal crashes
annually in each state has proven invaluable to researchers seeking to study the effects
of state-level legislative interventions to reduce alcohol-related traffic deaths.
Unfortunately, without comprehensive testing for alcohol and determination of
college student status of all persons who die from unnatural deaths, we lack the
most dependable yardstick by which to measure the magnitude of alcohol-related
injury death among college students, and whether this figure is changing over time.
Interventions to Reduce College Drinking
The increase in the past 3 years in alcohol-related traffic and other unintentional
injury deaths among 18–24-year-olds both in college and not in college underscores
the need for colleges and their surrounding communities to expand and strengthen
interventions demonstrated to reduce excessive drinking among college students
and their same-age noncollege counterparts.
Of note, heavy-drinking college students not only place their own health at risk,
but also they jeopardize the well-being of others. As many as 46% of the 4553
people killed in 2001 in crashes involving 18–24-year-old drinking drivers are
persons other than the drinking driver, and the total deceased has increased 33%
from 3425 to 4553 between 1998 and 2001. Further, surveys both in 1999 and
again in 2001 indicate annually over 600,000 college students nationwide were hit
or assaulted by a drinking college student, and in 2001 97,000 students were the
victim of a date rape or assault perpetrated by a drinking college student. Colleges
and surrounding communities have an obligation to protect people from potential
harm contributed by excess college drinking.
The recent report on college drinking (57) and its background reports (23) and
the National Academy of Sciences Report on Underage Drinking (52) identified
numerous individually oriented counseling approaches, environmental interventions,
and comprehensive community interventions that can reduce drinking and
related problems among college students and the college age population. These
documents summarize scientifically valid approaches for effective prevention, and
some believe they establish a new legal standard by which the adequacy of any
college or university’s efforts can be judged (44). See Table 2.
Individually Oriented Interventions
Larimer & Cronce (43) reviewed individually oriented strategies to reduce problematic
alcohol consumption by college students from 1984 to 1999. Studies were
included in this review if they had a control or comparison group and had at least
one change in drinking or alcohol consequences outcome. A total of 34 separate
studies were identified. The reviewers found little evidence for the effectiveness
of information-based and values-clarification programs. Several skills-based interventions
(13, 50, 60) resulted in decreases in alcohol consumption, including selfmonitoring/
self-assessment (21, 48) as well as expectancy-challenge procedures
(14) involving alcohol/placebo administration. Brief motivational interventions
had demonstrated effectiveness in a variety of contexts including selected high-risk
freshmen, high school classrooms, fraternity organizations, outpatient counseling
centers, and emergency rooms. Mailed graphic feedback alone in three studies (1,
75, 76) resulted in reductions in alcohol consumption equivalent or superior to
skills-based interventions with combined feedback.
Environmental Interventions: Legal Drinking Age of 21
The most powerful environmental intervention to reduce drinking among college
students is the minimum legal drinking age of 21. In 1984, when 25 states had a
legal drinking age of 21, the U.S. Congress passed legislation that would withhold
highway construction funds from states that did not make it illegal to sell alcohol
to people younger than 21. By 1988, all states adopted this law. A review of
more than 49 studies of legal drinking age changes revealed that in the 1970s and
1980s, when many states lowered the drinking age, alcohol-related traffic crashes
increased 10%. In contrast, when states increased the legal drinking age to 21,
alcohol-related crashes among people younger than 21 decreased an average of
16% (64).Wagenaar&Toomey (74) reviewed more than 48 studies of the effects of
drinking age changes on drinking and 57 studies on traffic crashes. They concluded
that increases in the age of legal alcohol purchase and consumption have been the
most successful intervention to date in reducing drinking- and alcohol-related
crashes among persons under 21. One national study of laws raising the drinking
age to 21 indicated that persons who grew up in states with a drinking age of 21
relative to those with lower legal drinking ages drank less not only when they were
younger than 21, but also when they were ages 21–25 (58). NHTSA (54) estimates
that a legal drinking age of 21 saves 700–1000 lives annually, and that more than
21,000 traffic deaths have been prevented by such laws since 1976.
Zero tolerance laws, which make it illegal in every state for persons under 21
to drive after any drinking, have also contributed to declines in alcohol-related
traffic deaths among people younger than 21. A comparison of the first 8 states
to adopt zero tolerance laws with nearby states without such laws revealed a 21%
greater decline in zero tolerance law states in the proportion of fatal crashes among
drivers younger than 21 that were of the type most likely to involve alcohol (i.e.,
single-vehicle fatal crashes at night) (28). Wagenaar et al. (73) found that in the
first 30 states to adopt zero tolerance laws, relative to the rest of the nation, there
was a 19% decline in the proportion of people younger than 21 who drove after
any drinking and a 23% decline in the proportion who drove after 5 or more drinks.
Unfortunately, despite their demonstrated benefits, legal drinking age and zero
tolerance laws generally have not been vigorously enforced (38). Young drivers
are substantially underrepresented in the driving while intoxicated (DWI) arrest
population relative to their contributions to the alcohol crash problem (59, 70).
Younger drivers may be more likely to drink at locations where DWI enforcement
resources are less likely to be deployed. Young drivers with high BACs also are
more likely to be missed by police at sobriety checkpoints (82).
Stepped-up enforcement of alcohol purchase laws aimed at sellers and buyers
can be effective (59, 69, 72) if resources are made available for this purpose.
Enforcement of zero tolerance laws is hindered in some states because their implied
consent laws require either an arrest for DWI or probable cause for a DWI arrest
before the evidentiary test can be done to prove a zero tolerance violation (19).
Thus in practice zero tolerance laws often are not enforced independently of DWI.
In states such as New Mexico, where this situation exists, most teenagers are
unaware that there is a zero tolerance law (20).
The National Academy of Sciences (52) reviewed the literature on price of alcohol
and alcohol-related problems and recommended that Congress and state legislators
raise excise taxes to reduce underage alcohol consumption and to raise additional
revenues to reduce underage drinking problems.
With rare exceptions (8, 15) research since the early 1980s generally has concluded
that increases in the price of alcohol beverages lead to reductions in drinking
and heavy drinking, as well as reductions in the adverse consequences of alcohol
use and abuse (6). Higher alcohol prices have also been found to reduce alcoholrelated
problems such as motor vehicle fatalities (16, 39, 62), robberies, rapes,
liver cirrhosis deaths (11, 12, 61), sexually transmitted diseases (9), and child
abuse (46, 47). Among moderate drinkers, investigators have estimated that a 1%
price increase results in a 1.19% decrease in consumption (45). Younger, heavier
drinkers tend to be more affected by price than older, heavier drinkers (7, 22, 39,
68), perhaps because younger drinkers have less discretionary income. Laixuthai
& Chaloupka (42), Grossman et al. (25), and Coate & Grossman (10) all found increasing
the price of alcohol reduces the percent of youths who drink infrequently
and produces even greater percentage declines in youths who drink frequently.
Research taking into account the addictive nature of alcohol shows that the
long-term price elasticity is well above short-term elasticity (24). Kenkel (39)
reported a 10% increase in the price of alcohol would reduce DWI 7%among men
and 8% among women, and among persons under 21 this action would produce a
13% decrease among men and a 21% decrease among women.
If, as recommended by the National Academy of Sciences Report (52), revenues
generated by alcohol tax increases to raise beverage prices are in turn earmarked
for programs and enforcement of policies known to reduce underage drinking,
reductions in underage drinking problems could exceed deductions associated
with alcohol price increases alone.
Other Environmental Interventions
Alcohol outlet density has been associated with alcohol-related problems (26) and
reducing outlet density may in turn reduce drinking-related problems. Wechsler
et al. (81) found that students who attend colleges in states that have more restrictions
on underage drinking, high volume consumption, and sales of alcohol
beverages and which devote more resources to enforce drunk-driving laws, report
less drinking and driving. Laws in these states included prohibitions against using
a false identification, restrictions on attempting to buy or consume for those
under the legal drinking age, enforcement of a clerk age minimum, and maintenance
of minimum mandatory postings of warning signs in retailers to potential
underage buyers. Laws pertaining to volume alcohol sales were keg registration, a
statewide 0.08 g/dl per se BAC law, and restrictions on happy hours, open alcohol
containers, beer sold in a pitcher, and billboards and advertising. The availability
of large volumes of alcohol (24- and 30-can cases of beer, kegs, party balls), low
sale prices, and frequent promotions and advertisements at both on- and off-premise
establishments were also associated with higher binge drinking rates on the college
Shults (64) also reviewed 19 studies of states lowering legal blood alcohol
limits for persons above 21 to 0.08% and reported that this law cut alcohol-related
fatalities on average by 7% and concluded that there is strong evidence in favor of
such a change.
Comprehensive Community Interventions
Several carefully conducted community-based initiatives have had particular success
in reducing drinking- and/or alcohol-related problems among young people
(32). These programs typically coordinate efforts of city officials from multiple
departments of city government, school, health, police, alcohol beverage control,
etc.; concerned private citizens and their organizations; students; parents; and
merchants who sell alcohol. Often multiple intervention strategies are incorporated
into the programs, including school-based programs involving students, peer
leaders, and parents; media advocacy; community organizing and mobilization;
environmental policy change to reduce alcohol availability to youth; and heightened
enforcement of laws regulating sales and distribution of alcohol and laws to
reduce alcohol-related traffic injuries and deaths.
Three comprehensive community programs in particular have shown reduction
in alcohol problems among college-age youth: the Communities Mobilizing for
Change Program (71, 72), the Community Trials Program (35), and the Saving
Lives Program (34). Two programs (35, 71, 72) concentrated program efforts
on underage alcohol purchase attempt surveys with feedback to alcohol sales
merchants and the community about the proportion of attempts that resulted in
sales and penalties for continued violations. Two programs (34, 35) focused on
publicized police enforcement of drinking driver laws and alcohol service laws, and
one (34) targeted risky motorist behaviors—such as speeding, running red lights,
failing to wear safety belts, and yielding to pedestrians in crosswalks—engaged
in disproportionally by drinking drivers.
Relative to the comparison communities, the Communities Mobilizing for
Change communities achieved a 17% increase in outlets checking the age identification
of youthful-appearing alcohol purchasers, a 24% decline in sales by bars and
restaurants to potential underage purchasers, a 25% decrease in the proportion
of 18–20-year-olds seeking to buy alcohol, a 17% decline in the proportion of older
teens who provided alcohol to younger teens, and a 7% decrease in the percentage
of respondents younger than 21 who drank in the previous 30 days (71). Further,
drinking and driving arrests declined significantly among 18–20-year-olds, and
disorderly conduct violators declined among 15–17-year-olds (72).
In the Community Trials Program, single-vehicle crashes at night, a measure
of alcohol-related crashes, declined 11% more in program than in comparison
communities. Alcohol-related trauma visits to emergency departments declined
In the Saving Lives Program (34) the proportion of drivers younger than 20
who reported in telephone surveys driving after drinking declined from 19% to
9% over the course of the program. The proportion of vehicles observed speeding
through use of radar was cut in half, and there was a 7%increase in safety belt use.
Minimal change in these outcomes occurred in comparison areas. Fatal crashes
declined from 178 during the 5 preprogram years to 120 during the 5 program
years, a 25% greater reduction than in the rest of Massachusetts. Fatal crashes
involving alcohol declined 42%, and the number of fatally injured drivers with
positive BACs declined 47%, relative to the rest of Massachusetts. Visible injuries
per 100 crashes declined 5% more in Saving Lives cities than in the rest of the state
during the program period. The fatal crash declines were greater in all six program
cities relative to comparison areas, particularly among drivers ages 15–25.
Weitzman et al. (83) recently evaluated the impact of college/community partnerships
implementing environmentally based interventions to reduce drinking
and related problems specifically among college students. Interventions included
in the A Matter of Degree (AMOD) program included keg registration, mandatory
responsible beverage service, increased enforcement of community police collaboration
or wild party enforcement, substance-free residence halls, and a variety of
alcohol bars advertising environment with change. Of the ten AMOD programs,
the five that most vigorously implemented these interventions achieved significant
reductions in binge and frequent binge drinking, frequent intoxication, driving
after drinking, alcohol-related injury, and a variety of other alcohol-related problems.
Relative to control colleges, significant reductions were observed also in the
proportion of students who reported being assaulted by another drinking college
Binge drinking and particularly DWI among college students and others in the 18–
24 age group has increased since 1998, and alcohol-related deaths have increased
significantly more than the population totals for that age. Colleges and the communities
in which they are located have an obligation to control the harms to others
posed by college-age drinkers, regardless of whether these drinkers are college
students. Although a high percentage of 18–24-year-old college students drink
heavily and engage in behaviors, such as driving a motor vehicle after drinking,
that pose risk to themselves and others, there are so many more 18–24-year-olds
not in college that this population actually accounts for more heavy drinkers, drinking
drivers, and alcohol-related deaths. In 2001, while 3.8 million college students
ages 18–24 engaged in heavy (5+ drinks) drinking episodes, so too did 7.6 million
18–24-year-olds who were not in college. While 2.8 million college students this
age drove under the influence of alcohol, so too did 4.5 million persons that age
who were not in college. While in 2001 nearly 1349 18–24-year-old college students
died in alcohol-related motor vehicle crashes, among all 18–24-year-olds,
there were 4216 of these deaths in 2001. While more than 300 college students
ages 18–24 died from other unintentional alcohol-related injuries, among all 18–
24-year-olds, 1151 individuals died from alcohol-related nontraffic unintentional
injuries in 2001.
Moreover, while young adults ages 18–24 have the highest rates of binge drinking
(5+ drinks at a time) than do other adults, persons over age 26 account for two
thirds of all binge drinking episodes (51). Also, while the highest rates of alcoholrelated
traffic deaths are among 18–24-year-olds, they accounted for only 24%
of alcohol-related traffic deaths and 9% of all other alcohol-related unintentional
deaths in 2001; this fact suggests that efforts are needed to reduce alcohol-related
traffic and unintentional injury deaths among persons of all ages, including college
Further, new research indicates that persons who drink to excess even before
they enter college are more likely to experience alcohol-related problems both
in high school and in college (33). According to the CDC National Youth Risk
Behavior Survey, in 2001 47% of high school students (over 7 million) drank
alcohol in the previous 30 days and 34% (over 5 million) drank at least 5 drinks
within a 2-hour period at least once in the previous 30 days. Thirteen percent
or 1.9 million individuals drove after drinking in the previous 30 days, and 31%
(4.6 million) rode with a drinking driver (27). Further, the average age of starting
to drink is declining (66). In 2001, 29% of high school students reported that they
began drinking before age 13 (27). Analyses of the 1999 CAS among college
students 19 and older revealed that the younger college students were when they
first drank to intoxication (got drunk), the more likely they were to experience
alcohol dependence in college, to engage in frequent heavy episodic drinking, to
drive after drinking and heavy (5+drinks) drinking, to ride with drunk drivers, to be
injured under the influence of alcohol (31), and to have unplanned and unprotected
sex after drinking (29). Community alcohol policy enforcement targeting high
school students may have carryover effects in college years.
Because increased efforts to enforce underage drinking laws at the community
level have reduced underage drinking, alcohol-related assault, emergency department
visits, and alcohol-related fatal crashes involving people of college age (34,
35, 71, 72), it is important that colleges and their surrounding communities collaborate
in these efforts. These efforts can include individually oriented screening
and counseling strategies of proven efficiency among college and adolescent
populations as well as environmental interventions such as alcohol tax increases,
heightened education, and enforcement of minimum legal drinking age and zero
tolerance laws. College crackdowns on campus drinking absent community support
may drive problematic drinking off campus. Community crackdowns without
college support may similarly drive drinking problems back onto campus. Moreover,
community efforts to reduce underage drinking are needed to prevent the
development of unsafe underage drinking practices before they spill over into the
