Facts about Alcohol
Alcohol, the most widely used psychoactive drug in the United States,
has unique pharmacological effects on the person drinking it
Alcohol contributes to 100,000 deaths annually, making it the third
leading cause of preventable mortality in the US, after tobacco and
diet/activity patterns
Among 9,484 deaths attributed to non-medical
use of other drugs in 1996, 37% also involved alcohol
More than seven percent of the population ages
18 years and older--nearly 13.8 million Americans--have problems with drinking,
including 8.1 million people who are alcoholic. Almost three times as
many men (9.8 million) as women (3.9 million) are problem drinkers, and
prevalence is highest for both sexes in the 18-to-29-years-old age group
About 43% of US adults--76 million
people--have been exposed to alcoholism in the family: they grew up with
or married an alcoholic or a problem drinker or had a blood
relative who was ever an alcoholic or problem drinker
62% of high school seniors report that they
have been drunk; 31% say that have had five or more drinks in a row during the
last two weeks
People who begin drinking before age 15
are four times more likely to develop alcoholism than those who begin at
age 21
From 1985 to 1992, the economic costs of alcoholism
and alcohol-related problems rose 42% to $148 billion. Two-thirds of the
costs related to lost productivity, either due to alcohol-related illness
(45.7%) or premature death (21.2%). Most of the remaining costs were in the
form of health care expenditures to treat alcohol use disorders and the
medical consquences of alcohol consumption (12.7%), property and administrative
costs of alcohol-related motor vehicle crashes (9.2%), and various additional
costs of alcohol-related crime (8.6%). Based on inflation and population
growth, the estimated costs for 1995 total $166.5 billion
Nearly one-fourth of all persons admitted to
general hospitals have alcohol problems or are undiagnosed alcoholics
being treated for the consequences of their drinking
On average, untreated alcoholics incur
general health care costs at least 100% higher than those of nonalcoholics, and
this disparity may exist as long as 10 years before entry into treatment
Based on victim reports, each year 183,000
(37%) rapes and sexual assaults involve alcohol use by the offender, as
do just over 197,000 (15%) of robberies, about 661,000 (27%) aggravated
assaults, and nearly 1.7 million (25%) simple assaults
Alcohol is typically found in the offender, victim or both in about
half of all homicides and serious assaults, as well as in a high percentage of
sex-related crimes, robberies, and incidents of domestic violence, and
alcohol-related problems are disproportionately found among both juvenile and
adult criminal offenders
Fetal alcohol syndrome (FAS), which can occur when women
drink during pregnancy, is the leading known environmental cause of mental
retardation in the Western World
Historical Comparison on Alcoholism
Alcoholism 30 years ago
- Little was known about he genetic basis of alcoholism or when the nervous system changes that occur as a result of heavy drinking
- Alcoholism was thought to be a disease of middle age
- Antabuse® (disulfiram) was the only medication approved for treating alcoholism. Antabuse® produces acute sensitivity to alcohol. This sensitivity causes a highly unpleasant reaction when the patient ingests even a small amount of alcohol.
- Other treatments included various behavioral approaches, mostly group counseling and referral to Alcoholics Anonymous. These treatments were only offered in intensive programs provided at specific locations separated from mainstream health care.
- Research seems to indicate relatively few people with alcoholism ever receive treatment
Alcoholism Today
- Researchers have identified genes that increase an individual’s risk for alcoholism, as well as genes that protect against alcohol problems.
- The neural basis of alcoholism was clarified. Research showing that drinking is influenced by multiple neurotransmitter systems, neuromodulators, hormones and intracellular networks provides evidence of a number of potential target sites for which new medications may be developed
- Multiple excellent animal models provide valuable tools for today’s researchers
- Clinicians have access to a wide range of treatment options that can be tailored to patient’s specific needs and a broad array of drinking problems can be effectively treated by non-specialists
- Screening and brief intervention – one to four repeated short counseling sessions focused on increasing motivation to reduce drinking has recently emerged as an effective strategy for addressing high-risk drinking
- Investigators developed screening tools that allow clinicians to quickly and reliably determine if their patients’ alcohol consumption patterns place them at risk for future adverse consequences. Studies show that brief interventions delivered in trauma units can reduce subsequent drinking and injuries.
- Several behavioral approaches, such as motivational enhancement therapy, cognitive-behavioral therapy and 12-step facilitation are effective in treating alcoholism, offering the patient and therapist a choice of approach. Brief counseling by a health care professional combined with medication recently was found to be as effective as specialized counseling. Thus, it may be possible to provide access to effective treatment to many p more people in primary care and mental health clinics
- When used in conjunction with behavioral therapies, medications improve the chance for recovery and the lives of those who suffer from alcoholism
Alcohol Addiction
· Addiction researchers and treatment professionals have long known that drug addiction and alcohol abuse are closely associated. In the last decade, research has broadened our understanding of many behavioral mechanisms common to both disorders. Yet, while two in five patients are addicted to both drugs and alcohol, the treatment they are likely to receive will target only one disorder. A lack of science-based information on alcohol and addiction treatment of drug and alcohol abuse limits the ability of treatment professionals to provide the comprehensive treatment these patients need.
· Recent research suggests some medications developed to treat addiction or alcohol abuse may be useful for treating both alcohol and addiction. This information, along with our increased understanding of the underlying factors that drive drug and alcohol abuse, provides a strong rationale for a coordinated research effort to meet the critical need for treatments for people suffering from both disorders. Toward that end, NIDA and the National Institute on Alcohol Abuse and Alcoholism (NIAAA) have issued a joint program announcement to spur both drug and alcohol abuse researchers to investigate all aspects of pharmacological treatment for dually addicted patients.
|
Recent research suggests that some medications developed to treat either drug or alcohol abuse may be useful in treating co-occurring substance abuse. |
· Coordinated research on addiction and alcohol patients will address the needs of the overwhelming number of Americans who abuse both alcohol and illicit drugs. More than 2.4 million of the 5.6 million people who abused illicit drugs in 2001 also abused alcohol, according to the National Household Survey on Drug Abuse. In fact, the more heavily someone abused alcohol, the more likely he or she was to use illicit drugs, the survey found. In 2001, nearly two of every three American teenagers, ages 12 to 17, who engaged in frequent drinking binges also abused drugs. In comparison, only 1 in 20 young people who didn't drink at all used drugs.
· The substantial portion of addiction and alcohol abusing patients in community treatment programs provides additional evidence of the need for science-based information on treating dual addiction. Patients who abuse both drugs and alcohol accounted for more than 42 percent of admissions to substance abuse treatment facilities reported by State agencies in 2000, the last year for which these data are published. Alcohol abuse is even more likely among patients who abuse certain drugs, such as cocaine, methamphetamine, and marijuana. For example, more than half of cocaine-abusing patients who entered treatment in 2000 also abused alcohol.
|
We aim to generate a broad spectrum of useful clinical information about appropriate sequencing or combining of medications and behavioral therapies, possible drug interactions that could affect optimal dosages, and unique requirements of specific groups of dually addicted patients... |
· To develop effective treatments for patients who have addiction and alcohol dependence, we need to understand why so many people do so. Part of the answer probably has to do with genes--underlying genetic variations that may play a role in common brain mechanisms that fuel both disorders. NIDA-supported brain imaging studies conducted at Brookhaven National Laboratory in Upton, New York, have documented similarities in the structure and function of the brains of alcoholics and chronic cocaine abusers that appear to be implicated in the abuse of both substances. Individuals with either disorder have low levels of dopamine D2 receptors in the brain's reward pathways that may impair their capacity to derive pleasure from normally rewarding activities. This deficit may make them more vulnerable to the rewarding effects of alcohol and cocaine.
· Individuals with addiction and alcohol dependence also may combine alcohol and illicit drugs because of interactions between abused substances in the body. Because both drugs and alcohol activate brain areas involved in reward, combining substances may increase these effects. Other alcohol-drug interactions may counter unpleasant effects that often accompany or follow substance abuse. Clinical reports suggest that cocaethylene, a combined cocaine-alcohol metabolite that is formed in the body following concurrent alcohol and cocaine use, appears to reduce the anxiety that can accompany cocaine use. Recent research in rats confirms that cocaethylene plasma levels remain high as cocaine levels fall, producing a delayed, relatively long-lasting rewarding effect that may counter the aversive effect induced when cocaine plasma levels recede.
· While the perceived benefits of combining alcohol and drug addiction may play a big part in the high percentages of people who do so, the addictive effects and harmful consequences of both substances increase when they are used together. Dually addicted patients are more likely to drop out of treatment and have poorer results than patients who abuse only one substance. However, since most studies on treating drug and alcohol abuse have examined these disorders separately, drug and alcohol treatment counselors now have little science-based information on which to base their treatment of these patients.
· Drug addiction and alcohol abuse wreak incalculable damage on individuals, families, and communities. When they occur together, these disorders double the challenge to researchers and treatment providers. Now, NIDA and NIAAA have launched a concerted scientific response to address these challenges. Ultimately, this expanded research will fuel the development of new treatments that will enable substance abuse treatment programs to more effectively meet the needs of the many patients who abuse both alcohol and illicit drugs.
· The National Institute on Drug Abuse (NIDA) is part of the National Institutes of Health (NIH) , a component of the U.S. Department of Health and Human Services.

New Advances in Alcohol Treatment
More than 700,000 Americans receive alcohol treatment on any given day.
However, the techniques of alcoholism therapy have traditionally been based on clinical
experience and intuition, with little rigorous validation of their
effectiveness. Over the past 20 years, modern methods of evaluating medical
therapies have been increasingly applied to alcoholism treatment. These methods
include the use of control groups for comparison purposes, random assignment of
study participants to different treatment groups and, to the greatest extent
possible, follow-up of all patients who entered the study. This issue focuses
on the results of recent controlled clinical studies on the effectiveness of
self-help groups, psychosocial approaches, and medications in achieving and
maintaining abstinence.
Twelve-Step Self-Help Alcohol
Treatment Programs
Self-help groups are the most commonly sought source of help for alcohol-related
problems. Alcoholics Anonymous (AA), one of the most commonly known self-help
groups, outlines 12 consecutive activities, or steps, that alcoholics should
achieve during the recovery process. Alcoholics can become involved with AA
before entering professional treatment, as a part of it, or as aftercare
following professional treatment. Although AA appears to produce positive
outcomes in many of its members, its efficacy has rarely been assessed in
randomized clinical trials.
One randomized study of patients entering employee assistance
programs compared inpatient treatment combined with AA with referral to AA
alone. This study found that inpatient treatment, a combination of professional
treatment and AA, will achieve better results for more people than AA alone.
Ouimette and colleagues, as part of a nonrandomized observational study
involving 3,000 patients in Department of Veterans Affairs hospitals, compared
predominantly 12-step programs with predominantly cognitive-behavioral programs
as well as with courses of therapy that combined both approaches. In
cognitive-behavioral therapy, the therapist helps the client learn new skills
to cope with problems and to change harmful behavior patterns, such as alcohol
abuse. One year after completion of treatment, the three types of programs had
produced comparable improvements on measures of alcohol consumption and related
problems. However, participants in the 12-step programs achieved more sustained
abstinence and higher rates of employment compared with participants in the
other two programs. Interpretation of these results is complicated by the
nonrandom assignment of patients to the different treatment types.
The beneficial effects of AA may be attributable in part to the
replacement of the participant's social network of drinking friends with a
fellowship of AA members who can provide motivation and support for maintaining
abstinence. In addition, AA's approach often results in the development of
coping skills, many of which are similar to those taught in more structured
psychosocial treatment settings, thereby leading to reductions in alcohol
consumption.
Psychosocial Therapy
The following sections deal with selected recent approaches or considerations
relevant to the psychosocial treatment of alcohol problems.
Alcohol Treatment using Motivational
Enhancement Therapy
Developed specifically for Project MATCH, motivational enhancement therapy
begins with the assumption that the responsibility and capacity for change lie
within the client. The therapist begins by providing individualized feedback
about the effects of the patient's drinking. Working closely together,
therapist and patient explore the benefits of abstinence, review treatment
options, and design a plan to implement treatment goals. Analysis suggests that
MET may be one of the most cost-effective of available treatment methods. In
one study, the motivational interviewing technique-a key component of MET-was
shown to overcome patients' reluctance to enter treatment more effectively than
did conventional techniques.
Alcohol Treatment for Couples Therapy
Evidence indicates that involvement of a nonalcoholic spouse in an alcohol
treatment program can improve patient participation rates and increase the
likelihood that the patient will alter drinking behavior after treatment ends.
There are various approaches to marital family therapy. Behavioral-marital
therapy combines a focus on drinking with efforts to strengthen the marital
relationship through shared activities and the teaching of communication and
conflict evaluation skills. O'Farrell and colleagues combined couples therapy
with the learning and rehearsal of a relapse prevention plan. Among alcoholics
with severe marital and drinking problems, the combination approach produced
improved marital relations and higher abstinence rates through 30 months of
follow-up compared with patients undergoing only BMT.
Brief Alcohol
Treatment Interventions
Many persons with alcohol-related problems receive counseling from primary care
physicians or nursing staff in the context of five or fewer standard office
visits. Such treatment, known as brief intervention, generally consists of
straightforward information on the negative consequences of alcohol consumption
along with practical advice on strategies and community resources to achieve
moderation or abstinence. Two controlled trials in the United States and Canada
demonstrated that this approach reduced drinking, alcohol-related problems and
patients' use of health care services. Most brief interventions are designed to
help those at risk for developing alcohol-related problems to reduce their
alcohol consumption. Alcohol-dependent patients are encouraged to enter
specialized treatment with the goal of complete abstinence.
The brief intervention approach has also been successfully
applied outside the primary care setting. Evidence suggests that 25 to 40
percent of trauma patients may be alcohol dependent. Gentilello and colleagues
conducted a randomized controlled study among patients in a trauma center who
had detectable blood alcohol levels at the time of admission. The researchers
found that a single motivational interview at or near the time of discharge
reduced drinking levels and re-admission for trauma during 6 months of
follow-up. Monti and colleagues conducted a similar randomized controlled study
among youth ages 18 to 19 admitted to an emergency room with alcohol-related
injuries. After 6 months, although all participants had decreased their alcohol
consumption, the group receiving brief intervention had a significantly lower
incidence of drinking and driving, traffic violations, alcohol-related
injuries, and alcohol-related problems.
Brief intervention among freshman college students previously
identified as being at high risk for harmful consequences of heavy drinking has
been shown to result in a significant decline in alcohol-related problems.
Treatment of Alcohol and Nicotine
Addiction Together
Nicotine and alcohol interact in the brain, each drug possibly affecting
vulnerability to dependence on the other. Consequently, some researchers
postulate that treating both addictions simultaneously might be an effective,
even essential, way to help reduce dependence on both. A recent study by Hurt
and colleagues showed that treatment for nicotine dependence did not interfere
with abstinence from alcohol or other drugs. Furthermore, such concurrent
treatment not only enhanced cessation from smoking, it also did not induce
already abstinent smokers to relapse to drinking.
Alcohol Treatment utilizing
Pharmacotherapy
More recently, research has focused on the development of medications for
blocking alcohol-brain interactions that might promote alcoholism. In 1995 the
U.S. Food and Drug Administration approved the use of the medication naltrexone
(ReViaTM) as an aid in preventing relapse among recovering alcoholics who are
simultaneously undergoing psychosocial therapy. This approval was based largely
on two randomized controlled studies that showed decreased alcohol consumption
for longer periods in naltrexone-treated patients compared with those who
received a placebo.
As is the case with all diseases, however, naltrexone is only
effective if taken on a regular basis (34). Like all medications, naltrexone
has side effects. One recent study reported a high rate of side effects, which
probably explains why this study, in contrast with most other studies, failed
to find naltrexone effective.
Acamprosate showed promise in treating alcoholism in several
randomized controlled European trials involving more than 3,000 alcoholic
subjects who were also undergoing psychosocial treatment. Analysis of combined
results showed that more than twice as many alcoholics receiving acamprosate
remained abstinent up to 1 year compared with subjects receiving psychosocial
treatment alone.
Research suggests that some medications may be more effective
for certain types of alcoholics. For example, when ondansetron (Zofran®) was
combined with psychotherapy, alcoholics who had begun drinking heavily before
age 25 (i.e., early-onset alcoholics) decreased their alcohol consumption and
increased their number of abstinent days, but later onset alcoholics did not
Sertraline (Zoloft®), in contrast, appears to reduce drinking in late-onset,
but not early-onset, alcoholics (38). However, fluoxetine (Prozac®), a
medication related to sertraline, has not been found to be effective in
late-onset alcoholism.
In conclusion, research supports the concept of using
medications as an adjunct to the psychosocial therapy of alcohol abuse and alcoholism.
However, additional clinical trials are required to identify those patients
most likely to benefit from such an approach, to determine the most appropriate
medications for different patient types, to establish optimal dosages, and to
develop strategies for enhancing patient compliance with medication regimens.
New Advances in Alcohol Treatment
Alcoholism clinicians have access today to a wide range of treatment options
for their patients. Some of these treatments, such as 12-step self-help programs,
have been around a long time. Others-including brief intervention and various
therapies borrowed from other fields, such as motivational enhancement therapy
and couples therapy-are relatively new concepts that have been shown to be
effective in reducing the risk for alcohol-related problems. The key change
that has occurred, of course, is the advent of alcoholism clinical research,
which over the past 15 years or so has made significant progress toward
rigorous evaluation of both existing therapies and newly developed therapies
for use in treating alcohol-related problems. Finally, continued research on
alcohol's effects in the brain and on the links between brain and behavior,
which has already led to the development of medications to reduce craving, is
likely to provide clinicians with a range of highly specific medications that
will, when used in conjunction with behavioral therapies, improve the chance
for recovery-and the lives-of those who suffer from alcohol abuse and
dependence.
Alcohol Treatment using Naltrexone
The medication naltrexone and up to 20 sessions of alcohol counseling by a
behavioral specialist are equally effective treatments for alcohol dependence
when delivered with structured medical management, according to results from
"Combining Medications and Behavioral Interventions for Alcoholism"
(The COMBINE Study). Results from the National Institutes of Health-supported
study show that patients who received naltrexone, specialized alcohol
counseling, or both demonstrated the best drinking outcomes after 16 weeks of
outpatient treatment. All patients also received Medical Management (MM), an
intervention consisting of nine brief, structured outpatient sessions provided
by a health care professional. Contrary to expectations, the researchers found
no effect on drinking of the medication acamprosate and no additive benefit
from adding acamprosate to naltrexone.
NIH's National Institute on Alcohol Abuse and Alcoholism (NIAAA)
launched COMBINE in 2001 to identify the most effective current treatments and
treatment combinations for alcohol dependence. The largest clinical trial ever
conducted of pharmacologic and behavioral treatments for alcohol dependence,
COMBINE was carried out at 11 academic sites that recruited and randomly
assigned 1383 recently abstinent alcohol dependent patients to one of nine
treatment groups.
During the 16 weeks of treatment and 1 year after the treatment,
the researchers assessed the patients for the percentage of days
abstinent from alcohol and time to the first heavy drinking day, defined
as 4 or more drinks per day for women and 5 or more drinks per day for men.
They also assessed the odds of good clinical outcome, defined as abstinence or
moderate drinking without alcohol-related problems. As in other large clinical
trials, the researchers found that most patients showed substantial improvement
during treatment and that both the overall level of improvement and the
differences between treatment groups diminished during the follow-up period. In
the COMBINE study, however, naltrexone continued to show a small advantage for
preventing relapse at 1 year after the end of active treatment..
"These results demonstrate that either naltrexone or
specialized alcohol counseling--with structured medical management--is an
effective option for treating alcohol dependence," said Mark L.
Willenbring, M.D., Director, Division of Treatment and Recovery Research,
NIAAA. "Although MM is somewhat more intensive than the alcohol dependence
interventions offered in most of today's health care settings, it is not unlike
other patient care models such as initiating insulin therapy in patients with
diabetes mellitus. MM's application in primary care and general mental health
care settings would expand access to effective treatment dramatically, while
offering patients greater choice."
"The COMBINE results provide guidance for applying today's
treatment tools. NIAAA continues to explore new treatment tools in more than 50
current medication trials, studies to better understand the mechanisms of
action in behavioral treatments, and our search for new molecular targets and
novel compounds for clinical testing," according to Raye Z. Litten, Ph.D.,
Combines’ government director and co-leader of NIAAA medications development
team.
Alcohol Rehab
Alcohol rehab
(rehabilitation) is defined here as the process of treatment for alcohol abuse
and dependency, alcoholism. Each different level of care is designed to offer a
unique type of program or medical service. A person participating in the process
of recovery from their alcoholism needs some combination of these services,
also known as levels of rehab care.
The following six levels of rehab care are offered by the alcohol recovery
industry;
1.
Alcohol
Detox
Also known as inpatient, alcohol detox (detoxification) is
the initial, mandatory phase in the alcohol rehab process. It can be defined as
the process of having all of the alcohol out of a person’s body. Also known as
withdrawal, to insure the patient’s safety, must always be done under proper medical supervision.
2.
Outpatient
Alcohol Rehab
Outpatient therapy (intensive outpatient program), is
considered an intermediate level of alcohol rehab care. They offer a viable
alternative to 30 day residential programs. Strictly done as group therapy,
they meet 3 to 5 times per week, for 2 to 3 hours per session.
3.
Partial
Hospitalization
Partial hospitalization, also known as PHP, the patient
continues to reside at home, but commutes to a treatment center up to seven days
a week. They are either all morning or all afternoon alcohol rehab sessions,
including both group and individual counseling.
4.
Residential
Alcohol Rehab Care
Alcohol rehab often needs time spend in treatment on a full
time basis. The length of stay is generally 30 days. This allows the individual
time in a safe, structured environment, where therapy is done daily and
considered to be enough time to begin to form new habits.
5.
Extended
Alcohol Rehab Care
Long term, or extended alcohol rehab is time in a
full time residential environment for longer than 30 days. They are up to a
maximum of 90 days. This is often recommended for people who have been through
lower levels of care and been unsuccessful.
6.
Sober
Living
Sober living, also known as half-way houses or sober houses are the final step
in the alcohol rehab process. Clients are usually required to have a job,
attend meetings and live in a structured lifestyle for up to one year.
Finding the right level and the best facility for alcohol rehab can be difficult. Usually, the right first step is to have a complete assessment and evaluation done. For more information about alcohol rehab, fill out the form below. A professional counselor will respond immediately
Teens and Alcohol
Some abuse alcohol by drinking frequently or by binge drinking--often defined as having five or more drinks* in a row. A minority of teens may meet the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for alcohol dependence. The progression of drinking from use to abuse to dependence is associated with biological and psychosocial factors. This Alcohol Alert examines some of these factors that put youth at risk for drinking and for alcohol-related problems and considers some of the consequences of their drinking.
Thirteen- to fifteen-year-olds are at high risk to begin drinking. According to results of an annual survey of students in 8th, 10th, and 12th grades, 26 percent of 8th graders, 40 percent of 10th graders, and 51 percent of 12th graders reported drinking alcohol within the past month. Binge drinking at least once during the 2 weeks before the survey was reported by 16 percent of 8th graders, 25 percent of 10th graders, and 30 percent of 12th graders.
Males report higher rates of daily drinking and binge drinking than females, but these differences are diminishing. White students report the highest levels of drinking, blacks report the lowest, and Hispanics fall between the two.
A survey focusing on the alcohol-related problems experienced by 4,390 high school seniors and dropouts found that within the preceding year, approximately 80 percent reported either getting "drunk," binge drinking, or drinking and driving. More than half said that drinking had caused them to feel sick, miss school or work, get arrested, or have a car crash.
Some teens that drink later abuse alcohol and may develop alcoholism. Although these conditions are defined for adults in the DSM, research suggests that separate diagnostic criteria may be needed for youth.
While drinking may be a singular problem behavior for some, research suggests that for others it may be an expression of general teen turmoil that includes other problem behaviors and that these behaviors are linked to unconventionality, impulsiveness, and sensation seeking.
Teens and Alcohol - Teenage Binge Drinking
Binge drinking, often beginning around age 13, tends to increase during adolescence, peak in young adulthood (ages 18-22), then gradually decrease. In a 1994 national survey, binge drinking was reported by 28 percent of high school seniors, 41 percent of 21- to 22-year-olds, but only 25 percent of 31- to 32-year-olds. Individuals who increase their binge drinking from age 18 to 24 and those who consistently binge drink at least once a week during this period may have problems attaining the goals typical of the transition from adolescence to young adulthood (e.g., marriage, educational attainment, employment, and financial independence).
Consequences of Teens Using Alcohol
Of the nearly 8,000 drivers’ ages 15-20 involved in fatal crashes in 1995, 20 percent had blood alcohol concentrations above zero.
Surveys of teenagers suggest that alcohol use is associated with risky sexual behavior and increased vulnerability to coercive sexual activity. Among adolescents surveyed in New Zealand, alcohol misuse was significantly associated with unprotected intercourse and sexual activity before age 16. Forty-four percent of sexually active Massachusetts teenagers said they were more likely to have sexual intercourse if they had been drinking, and 17 percent said they were less likely to use condoms after drinking.
Survey results from a nationally representative sample of 8th and 10th graders indicated that alcohol use was significantly associated with both risky behavior and victimization and that this relationship was strongest among the 8th-grade males, compared with other students.
High doses of alcohol have been found to delay puberty in female and male rats, and large quantities of alcohol consumed by young rats can slow bone growth and result in weaker bones. However, the implications of these findings for young people are not clear.
