STUDY OF NORTHERN CALIFORNIA BARS AND RESTAURANTS LEADS TO QUESTIONS ABOUT THE
Guidelines about moderate drinking are based on a standard drink defined in the U.S. as one that contains about 14 grams of pure alcohol, typically the amount of alcohol found in 5 ounces of table wine. In a study expected to be published in the September issue of Alcoholism: Clinical and Experimental Research, researchers found that servings of wine and spirits in restaurants and bars are often 50 percent larger than the standard drink used in guidelines. That means that people may be consuming more alcohol than expected. Lead author William Kerr, a senior scientist at the Public Health Institute's Alcohol Research Group, and his colleagues analyzed 480 drinks collected in 80 bars and restaurants in Northern California. According to the study, the type of establishment, the region of Northern California, and the gender of the bartender did not seem to affect the sizes of the drink.

STUDY SHOWS CONSUMPTION OF ENGERY DRINKS IS A POTENTIAL PREDICTOR OF RISK BEHAVIOR
A March 2008 study in The Journal of American College Health found that the consumption of energy drinks is a potential predictor for risky behavior in college students. While the relationship has not been studied in a younger population, the consumption of these drinks may be an indicator that these young people may be especially drawn to taking risks. Energy drinks have come onto the scene relatively recently and are popular with young people including middle and high school students. According to The New York Times, May 26, 2008, about one-third of 12 to14 year olds say they consume energy drinks regularly. Health researchers and school officials are concerned since these drinks have been linked to reports across the country of nausea, abnormal heart rhythms, and emergency room visits.

CANADIAN REPORT ON AVOIDABLE COSTS OF ALOCOHOL ABUSE
The Centre for Addiction and Mental Health (CAMH) in Canada recently released a report that systematically estimated avoidable costs associated with alcohol abuse. The report found that implementing six interventions would save about $1 billion per year and approximately 800 lives. Dr. Jürgen Rehm, CAMH Senior Scientist, and his team focused on six interventions: (1) increasing taxes on alcohol, (2) lowering the blood alcohol concentration (BAC) legal limit from 0.08 percent to 0.05 percent, (3) implementing a zero tolerance BAC for all drivers under age 21, (4) increasing the legal minimum drinking age from 19 to 21 years of age, (5) making bars safer by enforcing drinking laws, and (6) completing routine screening by health care professionals (brief interventions).

CDC STUDY ON BINGE DRINKING PRESENTED AT NATIONAL CONFERENCE FOR EPIDEMIOLOGISTS
Binge drinking accounts for approximately half of the 75‚000 alcohol-attributable deaths in the United States every year. Dr Timothy Naimi‚ Medical Officer‚ Centers for Disease Control and Prevention (CDC)‚ presented research on binge drinking behavior at the Conference of State and Territorial Epidemiologists (CSTE) held June 8-12‚ 2008‚ in Denver‚ CO. Dr. Naimi's findings‚ generated from a CDC study that examined data from 14‚150 respondents to the Behavioral Risk Factor Surveillance Survey Binge Drinking Module during 2003-2004‚ included information about the location of most binge drinking‚ the beverage most often consumed‚ and the association with subsequent risky behavior.
Dr. Naimi reported that almost half of the binge drinking occurred in public places‚ with 20 percent of those who reported binge drinking in bars and clubs also reporting that they subsequently operated a motor vehicle; two-thirds of the time‚ beer was the beverage of choice; and 20 percent of underage respondents reported being able to buy their own alcohol at a store‚ bar‚ or restaurant although they are not of age to purchase alcohol legally.

STUDY SHOWS THAT EXTREME BINGE DRINKING ON 21ST BIRTHDAYS STILL COMMON
A report on the Today Show cited a New York Times story about the ritual of having 21 or more alcoholic drinks on one’s 21st birthday, which appears to be more common than expected. A new study from University of Missouri of 2,518 students showed that among students who drank alcohol to celebrate their 21st birthdays, 34 percent of the men and 24 percent of the women reported having 21 or more drinks. Based on the data, researchers estimated that half of the men and more than a third of the women had blood alcohol levels of 0.26 or higher, the level at which a person is severely impaired and at risk for choking on vomit or serious injury. Interest in the ritual may be spreading because people who attempt or succeed at the ritual post videos and photos of their binges on YouTube, Flickr, or MySpace. Clayton Neighbors, associate professor of psychiatry and behavioral sciences at the University of Washington Center for the Study of Health and Risk Behaviors in Seattle, is studying Internet-based interventions to combat the ritual. In a study of 316 students, those given Web-based information about drinking prior to their 21st birthdays drank less than students who didn’t receive the information. “One of the problems is a lot of these kids don’t realize that 21 drinks in an hour can kill you,’’ he said. One group that addresses this issue, Be Responsible About Drinking (B.R.A.D.), was started by family and friends of a Michigan State University student who died from extreme drinking on his 21st birthday. The group sends young people birthday cards prior to their 21st birthdays warning them about the dangers of alcohol poisoning. The site also includes numerous charts showing how drinks affect blood alcohol levels. April 03, 2008
SAMHSA RELEASES NEW NSDUH STATISTICS ON UNDERAGE DRINKING
SAMHSA’s National Survey on Drug Use and Health (NSDUH) released updated statistics on March 31 about underage drinking. The statistics appeared in The NSDUH Report, Quantity and Frequency of Alcohol Use among Underage Drinkers. According to the report, combined 2005 and 2006 data indicate that an annual average of 28.3 percent of persons aged 12 to 20 in the United States (an estimated 10.8 million annually) drank alcohol in the past month. Also, underage youth who drank in the past month used alcohol an average of 5.9 days and consumed an average of 4.9 alcoholic drinks on the days they drank. And, people under the legal age consumed, on average, more drinks per days on the days they drank in the past month than drinkers of legal age (4.9 drinks versus 2.8 drinks).

NIAAA’S APIS ANNOUNCES UPDATE OF ALCOHOL POLICY INFORMATION
The Alcohol Policy Information System (APIS), a project by the National Institute on Alcohol Abuse and Alcoholism, announces its latest update of State-by-State alcohol policies. The January 1, 2007 update is posted to the APIS Web site and covers the period 1/2/2006 through 1/1/2007. Among the most prominent changes related to underage drinking are the following: Hawaii and North Carolina have adopted laws that explicitly prohibit underage consumption of alcohol; Hawaii has adopted license suspension procedures for use of false IDs by minors to obtain alcohol; Oklahoma has targeted suppliers of false IDs to minors by adopting a provision prohibiting their lending, transfer, sale, and production; Connecticut, Oklahoma, and Rhode Island have adopted laws to impose criminal liability on those who host underage drinking parties; and North Carolina and Wyoming have adopted keg registration laws. For more information go to the APIS Web site; of particular interest is the Web page Highlight on Underage Drinking. March 20, 2008
CURBING TEEN DRINKING DIFFICULT IN URBAN AREAS
A new study has shown that a 3-year prevention program for Chicago middle-schoolers did not keep them from drinking or using drugs, despite the program’s previous success in rural Minnesota, where it reduced alcohol use 20 to 30 percent. The researchers studied 5,812 6th- 7th-, and 8th-graders in 61 public schools in mostly low-income communities in Chicago. The schools were grouped into neighborhood study units assigned randomly either for intervention or to serve as controls. Participating schools used an alcohol prevention curriculum in the classroom; these sessions were led by students. The family component included homework assignments that parents and children could complete together, organized events for families, and educational postcards sent to parents. The community components included youth-led community service projects and community organizing. At the end of the Chicago study, year-end surveys showed no difference in alcohol use between the children who took part in the project and those who did not. Lead author Kelli Komro says in a news release: “The intervention found to be effective in rural areas was not effective here, which really surprised us. This is an important finding to realize this program was not enough. The bottom line is this: Low-income children in urban areas need more, long-term intensive efforts.” Of the three program components, the family interventions were the most effective. One community activity worked well: in the neighborhoods where teams went to stores that sold alcohol and asked them not to sell to underage youth, selling alcohol to minors decreased by 64 percent. The study appears in the April 2008 Addiction (Vol. 103, pp. 606-618) (see abstract). March 20, 2008

STUDY OF DRINKING PATTERNS OF 6TH-GRADERS IN CHICAGO
Reuters reports that a new study of more than 4,000 6th-graders in Chicago schools has found that 17 percent of the children used alcohol in the past year. The study compares those who reported alcohol use in the past year to those who reported no use in a multiethnic, urban sample of sixth graders in 61 schools in Chicago in 2002. The study found that young adolescent alcohol users drink at higher rates than their peers throughout adolescence and appear to be less amenable to intervention. These children were more likely than their peers to get into fights, shoplift, or get into trouble at school. They also had a range of risk factors for early drinking, including delinquent or violent behavior, lack of adult supervision out of school, and having friends who drink alcohol. The researchers conclude that alcohol prevention should start in grade school and involve parents. Lead researcher Dr. Keryn Pasch, of the University of Minnesota School of Public Health in Minneapolis, suggests that school-based programs include take-home assignments or other activities that involve parents. She recommends that parents look for “teachable moments,” such as when drinking is portrayed on television. In addition, parents should not only tell their children not to drink, but also teach them how to refuse alcohol. The findings are reported in the journal Health Education & Behavior (OnlineFirst, February 26) (see abstract).

NSDUH STATE DATA RELEASED
The Substance Abuse and Mental Health Services Administration (SAMHSA) has released substance abuse data by State derived from its most recent National Survey on Drug Use and Health (NSDUH). The report, “State Estimates of Substance Use from the 2005-2006 National Surveys on Drug Use and Health,” includes rates for underage drinking and binge drinking, illegal drug use, serious mental illness, and tobacco use. According to the report, past month alcohol use for youths aged 12 to 17 decreased nationally from 17.1 to 16.6 percent between 2004-2005 and 2005-2006. Four States showed decreases in this age group: California (16.2 to 14.7 percent), Indiana (17.1 to 14.6 percent), South Dakota (22.0 to 18.4 percent), and Wisconsin (22.6 to 19.3 percent). Nationally, binge alcohol use among youths aged 12 to 17 fell from 10.5 percent to 10.1 percent in 2005-2006. The District of Columbia had the lowest binge-drinking rate in this age group at 7.3 percent and Montana had the highest at 15.3 percent. SAMHSA Administrator Terry Cline says in a press release, “This report shows that although states may be uniquely affected by serious public health problems like underage drinking, every state and region must confront these issues. By highlighting the nature and scope of the challenges affecting each state, we can help focus and target substance abuse and mental illness prevention and treatment resources.” March 13, 2008
EARLIER PARENTAL SUPERVISION MAY CURB COLLEGE DRINKING
Parental monitoring during high school has a protective effect on later college drinking, according to a study published last week. A press release says the researchers from the Center for Substance Abuse Research at the University of Maryland College Park interviewed more than 1,200 students as part of the College Life Study, an ongoing investigation of health-risk behaviors in college students, including alcohol and other drug use. The students were surveyed during the summer before they attended a large public university in the mid-Atlantic to assess their perception of parental rule-setting, supervision, consequences, and monitoring during the last high-school year as well as their alcohol consumption over the past year. The students were later followed up with a personal interview to assess their drinking during their first year of college. Among the study results were that higher levels of parental supervision were associated with lower levels of high-school drinking. Although parental supervision did not directly influence drinking in college, there was evidence that the more the students drank in high school, the more they drank in college. The authors point out that these results call into question the opinion of many parents that “responsible drinking” should begin in high school. Further research is needed to explore the extent and type of parental supervision that could reduce students’ drinking in college. The authors write: “In summary, the transition to college marks a high-risk period for escalation of alcohol consumption. Parents and prevention practitioners can benefit from evidence that points to specific parenting practices that might help reduce the risk for heavy drinking, while at the same time allow for appropriate levels of autonomy that are critical for young adult development.” The research was published in the online journal Substance Abuse Treatment, Prevention, and Policy (3:6) (see abstract).

RESISTANCE AND REFUSAL SKILLS HELP YOUTH AVOID DRINKING
A 3-year study of inner city middle-school students in New York City examined the impact of “media resistance skills” and “drug skill refusal techniques” on adolescent drinking. According to a press release, the results were taken from surveys of over 2,000 predominantly African-American adolescents from 13 inner-city junior high schools. The researchers, from Weill Cornell Medical College, found that 7th-graders who were critically aware of advertising (had media resistance skills) were significantly less likely to drink alcohol when they reached 9th grade. In addition, these same 7th-graders were more likely to have developed better skills for resisting peer pressure (drug skill refusal techniques) by the time they reached 8th grade, further reducing their likelihood of drinking. Lead author Dr. Jennifer Epstein says “There are many pressures on teens to drink. One very powerful influence is advertising—from television to billboards, it’s everywhere. Our study found their ability to be critically aware of advertising as well as their ability to resist peer pressure are both key skills for avoiding alcohol.” The study appears online in the journal Addictive Behaviors (print edition April 2008, Vol. 33, pp. 528-537).

DRINKING PATTERNS AND VICTIMIZATION LINKED IN WOMEN COLLEGE FRESHMEN
A new study assesses risk for physical and sexual victimization in female college freshmen, with regard to changes in their drinking behavior during the transition from high school to college. The researchers were specifically interested in how risk for victimization differed according to whether the women were continued abstainers, began drinking once in college (new drinkers), or continued drinking but either decreased, increased, or did not change their level of weekly drinking. For the study, the students were asked to report their alcohol and other drug use, psychological symptoms, number of sexual partners, and experiences with physical and sexual victimization for the year before entering college and the first year at college. In a news release, Principal Investigator Kathleen Parks, of the University at Buffalo Research Institute on Addictions, explains “Young women who had a history of physical victimization and greater psychological symptoms, and who began drinking during the first year at college had an increased likelihood of experiencing physical victimization. Women who had a greater number of psychological symptoms, more sexual partners and increased their weekly drinking had an increased likelihood of experiencing sexual victimization during the first year of college.” She continues, “This is the first study that we know of that has compared risk for physical and sexual assault among college women based on changes in drinking during this transition period. Clearly, abstaining from drinking is a protective measure. However, young college women should be aware that becoming a new drinker or increasing one’s drinking during this transition increases the likelihood of victimization.” The research appears in the January 2008 Journal of Studies on Alcohol and Drugs. (Vol. 69, pp. 65-74) (see abstract). The study was funded by the National Institute on Alcohol Abuse and Alcoholism. February 14, 2008
NIAAA ISSUES UPDATE ON COLLEGE DRINKING RESEARCH
In 2002, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) Task Force on College Drinking released A Call to Action: Changing the Culture of Drinking at U.S. Colleges, which included statistics conveying the magnitude of college drinking problems and their consequences. A new NIAAA report, What Colleges Need to Know Now: An Update on College Drinking Research, is now available that summarizes recent findings with updated statistics, analysis, and recommendations.

ALCOHOL USE BEFORE AGE 13 LINKED WITH VIOLENT BEHAVIORS
The relationship between early alcohol use initiation and violent and suicidal behaviors is the subject of a new study conducted by researchers from Georgia State University’s Institute of Public Health, according to a news release. The researchers analyzed data on 7th-graders taken from a 2004 survey of violence among public school students in a community defined as “high-risk” because of high levels of poverty, unemployment, serious crimes, and single-parent households. Among the results were that 35 percent of the 7th-graders had started drinking before age 13 (“preteen alcohol use initiators”). The youths who began drinking early were three times more likely than non-drinking peers to attempt suicide, and were more likely to be victims of dating and peer violence. Author Monica Swahn states, “Since early alcohol use was strongly associated with both dating violence victimization and suicide attempts, prevention efforts that delay or reduce adolescents’ alcohol use may prevent these forms of violence as well. A number of evidence-based strategies, such as enforcing minimum legal drinking age laws and increasing excise taxes on alcohol, are available but not fully implemented to prevent and reduce alcohol use among minors. Increased support of these strategies will be necessary to prevent alcohol abuse and the many health problems associated with its use among young people.” The study appears in the February issue of Pediatrics (Vol. 121, pp. 297-305) (see abstract).

PARENTAL DRINKING AND PARENTING PRACTICES INFLUENCE TEEN DRINKING
A newly published study investigates the effects of both parental drinking and parenting behaviors on teen drinking. An article on the Addiction Technology Transfer Center (ATTC) Web site reports that the researchers analyzed data on 2,402 male and 2,329 female teens and their parents gathered from an ongoing Finnish study of health-related behaviors and correlated risk factors. The teens answered questions about their alcohol use and intoxication at ages 14 and 17.5 and on their perceptions of the parenting they received. The parents were asked about their frequency of alcohol use and intoxication and about their lifetime prevalence of alcohol-related problems. The investigators found that parental alcohol use, intoxication, and problem drinking were associated with decreased monitoring of their children and with increased discipline. Decreased monitoring, in turn, was related to more adolescent alcohol use at age 14 and more frequent intoxication at both ages 14 and 17.5. Increased discipline was linked to more frequent alcohol use and intoxication in the teens aged 17.5, but not in the 14-year-olds. Thus parental monitoring has a protective effect, whereas excessive discipline may have the unintended effect of causing greater risk for alcohol use among older children who are seeking greater autonomy. Corresponding author Shawn Latendresse of the Virginia Institute for Psychiatric and Behavioral Genetics at Virginia Commonwealth University says “This awareness provides us with some tangible targets for prevention, that is, knowing where one’s children are, what they are doing, etc., and not exerting excessive control or discipline to the extent that it actually subverts a child’s need to develop their independence.” The study is in the February Alcoholism: Clinical & Experimental Research (Vol. 32, pp. 322-330) (see abstract).

EXCESSIVE DRINKING WHILE YOUNG TIED TO LATER HEALTH RISKS
A study found that excessive drinking in early life leads to later health problems, including abdominal obesity and low HDL cholesterol, which can lead to diabetes and cardiovascular disease. According to an article on the Scientific American Web site, researchers examined a group of people aged 35 to 80 who had started drinking early in life and consumed alcohol heavily as teens and young adults, but reduced consumption as they aged (including becoming abstinent in midlife). The researchers specifically looked at risk of metabolic syndrome, which means having three or more of the conditions that can lead to heart disease, stroke and diabetes (the conditions that form metabolic syndrome are abdominal obesity, high blood pressure, low levels of "good" HDL cholesterol, high blood sugar, and high triglyceride levels). They compared them with others who had consumed modest amounts of alcohol throughout their adult lives. Those who had consumed alcohol excessively while young were nearly a third more likely to have metabolic syndrome. The results were reported in the January Journal of Clinical Endocrinology & Metabolism (Vol. 93, pp. 154-161) (see abstract). |
