Questionable tactics in marketing

A new report studying marketing practices for alcohol in seven developing countries will be presented at the GAPC conference in Bangkok early next year. The study has been conducted by Tom Farrell, senior lecturer at Oxford Brookes University in England and Dr. Ross Gordon, research fellow at the University of Wollongong in Australia. They have analyzed a sample of 15 alcohol promotions against the regulatory codes governing such marketing in the UK, often cited as a ‘gold standard system’ according to the researchers. > > > > Read More

News Release - Study Underlines Potential of Anti-Stress Peptide to Block Alcohol Dependence

New research by scientists at The Scripps Research Institute has underlined the power of an endogenous anti-stress peptide in the brain to prevent and even reverse some of the cellular effects of acute alcohol and alcohol dependence in animal models. The work could lead to the development of novel drugs to treat alcoholism.

The new study, led by Scripps Research Associate Professor Marisa Roberto and published online ahead of print by the journal Biological Psychiatry, illuminates the cellular mechanisms that govern the transition from alcohol use to alcohol dependence. Specifically, the study examined the interaction between two competing agents—one a stress peptide that promotes excessive alcohol drinking, the other an anti-stress peptide that opposes it. The results confirm that drugs derived from the anti-stress peptide nociceptin could play an important role in treating a complex and multi-faceted disease.

"Alcohol affects a lot of systems in the brain, and there won't be a single pill that will cure the multiple and complex aspects of this disease," Roberto said. Instead, scientists are seeking to attack the disease from a variety of angles, and are investigating the many different areas of the brain that appear to play a role in the use and abuse of alcohol. > > > > Read More

Nociceptin/Orphanin FQ Blockade of Corticotropin-Releasing Factor-Induced Gamma-Aminobutyric Acid Release in Central Amygdala Is Enhanced After Chroni

The central nucleus of the amygdala (CeA) mediates stress- and addiction-related processes. Corticotropin-releasing factor (CRF) and nociceptin/orphanin FQ (nociceptin) regulate ethanol intake and anxiety-like behavior. In the rat, CRF and ethanol significantly augment CeA gamma-aminobutyric acid (GABA) release, whereas nociceptin diminishes it.

Using electrophysiologic techniques in an in vitro slice preparation, we investigated the interaction of nociceptin and CRF on evoked and spontaneous GABAergic transmission in CeA slices of naive and ethanol-dependent rats and the mechanistic role of protein kinase A.

In neurons from naive animals, nociceptin dose-dependently diminished basal-evoked GABA_A receptor-mediated inhibitory postsynaptic potentials (IPSPs) by decreasing GABA release and prevented, as well as reversed, CRF-induced augmentation of IPSPs, actions that required PKA signaling. In neurons from ethanol-dependent animals, nociceptin decreased basal GABAergic transmission and blocked the CRF-induced increase in GABA release to a greater extent than in naive controls.

These data provide new evidence for an interaction between the nociceptin and CRF systems in the CeA. Nociceptin opposes CRF effects on CeA GABAergic transmission with sensitization of this effect in dependent animals. These properties of nociceptin may underlie its anti-alcohol and anxiolytic properties and identify the nociceptin receptor as a useful therapeutic target for alcoholism.

News Release - Early Intervention Program Reduces Youth Substance Abuse in WV

A pilot program in Logan and Mercer counties is cutting down on youth substance abuse in the Mountain State. WV’s Substance Abuse Early Intervention Program (EIP) targets youth ages 12-18 who have just begun to use alcohol, tobacco, or other substances and/or are engaging in delinquent behavior often associated with substance use. Since its inception in 2010, 65 youth have completed the program, which enhances accurate understanding of the risks of alcohol, tobacco, & other drug (ATOD) use and develops ATOD refusal skills. The program also provides an alternative option for youth who may be on their way into the juvenile justice system. > > > > Read More

Differential Effects of Single Versus Repeated Alcohol Withdrawal on the Expression of Endocannabinoid System-Related Genes in the Rat Amygdala

Endogenous cannabinoids such as anandamide and 2-arachidonoylglycerol (2-AG) exert important regulatory influences on neuronal signaling, participate in short- and long-term forms of neuroplasticity, and modulate stress responses and affective behavior in part through the modulation of neurotransmission in the amygdala. Alcohol consumption alters brain endocannabinoid levels, and alcohol dependence is associated with dysregulated amygdalar function, stress responsivity, and affective control.

The consequence of long-term alcohol consumption on the expression of genes related to endocannabinoid signaling was investigated using quantitative RT-PCR analyses of amygdala tissue. Two groups of ethanol (EtOH)-exposed rats were generated by maintenance on an EtOH liquid diet (10%): the first group received continuous access to EtOH for 15 days, whereas the second group was given intermittent access to the EtOH diet (5 d/wk for 3 weeks). Control subjects were maintained on an isocaloric EtOH-free liquid diet. To provide an initial profile of acute withdrawal, amygdala tissue was harvested following either 6 or 24 hours of EtOH withdrawal.

Acute EtOH withdrawal was associated with significant changes in mRNA expression for various components of the endogenous cannabinoid system in the amygdala. Specifically, reductions in mRNA expression for the primary clearance routes for anandamide and 2-AG (fatty acid amide hydrolase [FAAH] and monoacylglycerol lipase [MAGL], respectively) were evident, as were reductions in mRNA expression for CB₁, CB₂, and GPR55 receptors. Although similar alterations in FAAH mRNA were evident following either continuous or intermittent EtOH exposure, alterations in MAGL and cannabinoid receptor-related mRNA (e.g., CB₁, CB₂, GPR55) were more pronounced following intermittent exposure. In general, greater withdrawal-associated deficits in mRNA expression were evident following 24 versus 6 hours of withdrawal. No significant changes in mRNA expression for enzymes involved in 2-AG biosynthesis (e.g., diacylglicerol lipase-α/β) were found in any condition.

These findings suggest that EtOH dependence and withdrawal are associated with dysregulated endocannabinoid signaling in the amygdala. These alterations may contribute to withdrawal-related dysregulation of amygdalar neurotransmission.

A Longitudinal Analysis of Circulating Stress-Related Proteins and Chronic Ethanol Self-Administration in Cynomolgus Macaques

Alcoholics have alterations in endocrine and immune functions and increased susceptibility to stress-related disorders. A longitudinal analysis of chronic ethanol intake on homeostatic mechanisms is, however, incompletely characterized in primates.

Plasma proteins (n = 60; Luminex) and hormones (adrenocorticotropic hormone [ACTH]; cortisol) were repeatedly measured in adult male cynomolgus monkeys (Macaca fascicularis, n = 10) during a 32-month experimental protocol at baseline, during induction of water and ethanol (4% w/v in water) self-administration, after 4 months, and after 12 months of 22-hour daily concurrent access to ethanol and water.

Significant changes were observed in ACTH, cortisol, and 45/60 plasma proteins: a majority (28/45) were suppressed as a function of ethanol self-administration, 8 proteins were elevated, and 9 showed biphasic changes. Cortisol and ACTH were greatest during induction, and correlations between these hormones and plasma proteins varied across the experiment. Pathway analyses implicated nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) and Janus kinase (JAK)/signal transducer and activator of transcription (STAT) as possible mediators of ethanol-induced effects on immune-related proteins in primates.

Chronic ethanol consumption in primates leads to an allostatic state of physiological compromise with respect to circulating immune- and stress-related proteins in NF-κB- and STAT/JAK-related pathways in correlation with altered endocrine activity.

Early Growth Response-1 Contributes to Steatosis Development After Acute Ethanol Administration

Previous work demonstrated that the transcription factor, early growth response-1 (Egr-1), participates in the development of steatosis (fatty liver) after chronic ethanol (EtOH) administration. Here, we determined the extent to which Egr-1 is involved in fatty liver development in mice subjected to acute EtOH administration.

In acute studies, we treated both wild-type and Egr-1 null mice with either EtOH or phosphate-buffered saline (PBS) by gastric intubation. At various times after treatment, we harvested sera and livers and quantified endotoxin, indices of liver injury, steatosis, and hepatic Egr-1 content. In chronic studies, groups of mice were fed liquid diets containing either EtOH or isocaloric maltose-dextrin for 7 to 8 weeks.

Compared with controls, acute EtOH-treated mice showed a rapid, transient elevation in serum endotoxin beginning 30 minutes after treatment. One hour postgavage, livers from EtOH-treated mice exhibited a robust elevation of both Egr-1 mRNA and protein. By 3 hours postgavage, liver triglyceride increased in EtOH-treated mice as did lipid peroxidation. Acute EtOH treatment of Egr-1-null mice showed no Egr-1 expression, but these animals still developed elevated triglycerides, although significantly lower than EtOH-fed wild-type littermates. Despite showing decreased fatty liver, EtOH-treated Egr-1 null mice exhibited greater liver injury. After chronic EtOH feeding, steatosis and liver enlargement were clearly evident, but there was no indication of elevated endotoxin. Egr-1 levels in EtOH-fed mice were equal to those of pair-fed controls.

Acute EtOH administration induced the synthesis of Egr-1 in mouse liver. However, despite its robust increase, the transcription factor had a smaller, albeit significant, function in steatosis development after acute EtOH treatment. We propose that the rise in Egr-1 after acute EtOH is an hepatoprotective adaptation to acute liver injury from binge drinking that is triggered by EtOH metabolism and elevated levels of endotoxin.

Synchrony of Corticostriatal-Midbrain Activation Enables Normal Inhibitory Control and Conflict Processing in Recovering Alcoholic Men

Alcohol dependence is associated with inhibitory control deficits, possibly related to abnormalities in frontoparietal cortical and midbrain function and connectivity.

We examined functional connectivity and microstructural fiber integrity between frontoparietal and midbrain structures using a Stroop Match-to-Sample task with functional magnetic resonance imaging and diffusion tensor imaging in 18 alcoholic and 17 control subjects. Manipulation of color cues and response repetition sequences modulated cognitive demands during Stroop conflict.

Despite similar lateral frontoparietal activity and functional connectivity in alcoholic and control subjects when processing conflict, control subjects deactivated the posterior cingulate cortex (PCC), whereas alcoholic subjects did not. Posterior cingulum fiber integrity predicted the degree of PCC deactivation in control but not alcoholic subjects. Also, PCC activity was modulated by executive control demands: activated during response switching and deactivated during response repetition. Alcoholics showed the opposite pattern: activation during repetition and deactivation during switching. Here, in alcoholic subjects, greater deviations from the normal PCC activity correlated with higher amounts of lifetime alcohol consumption. A functional dissociation of brain network connectivity between the groups further showed that control subjects exhibited greater corticocortical connectivity among middle cingulate, posterior cingulate, and medial prefrontal cortices than alcoholic subjects. In contrast, alcoholic subjects exhibited greater midbrain-orbitofrontal cortical network connectivity than control subjects. Degree of microstructural fiber integrity predicted robustness of functional connectivity.

Thus, even subtle compromise of microstructural connectivity in alcoholism can influence modulation of functional connectivity and underlie alcohol-related cognitive impairment.

Early age alcohol use and later alcohol problems in adolescents: Individual and peer mediators in a bi-national study.

This paper examines whether there is cross-national similarity in the longitudinal relationship between early age alcohol use and adolescent alcohol problems. Potential mechanisms underlying this relationship also are examined, testing adolescent alcohol use, low self-regulation, and peer deviance as possible mediators.

Students (N = 1,945) participating in the International Youth Development Study, a longitudinal panel survey study, responded to questions on alcohol use and influencing factors, and were followed annually over a 3-year period from 2002 to 2004 (98% retention rate). State-representative, community student samples were recruited in grade 7 in Washington State, United States (US, n = 961, 78% of those eligible; Mage = 13.09, SD = .44) and Victoria, Australia (n = 984, 76% of those eligible; Mage = 12.93, SD = .41). Analyses were conducted using multiple-group structural equation modeling.

In both states, early age alcohol use (age 13) had a small but statistically significant association with subsequent alcohol problems (age 15).

Overall, there was little evidence for mediation of early alcohol effects. Low self-regulation prospectively predicted peer deviance, alcohol use, and alcohol problems in both states.

Peer deviance was more positively related to alcohol use and low self-regulation among students in Victoria compared to students in Washington State.

The small but persistent association of early age alcohol use with alcohol problems across both samples is consistent with efforts to delay alcohol initiation to help prevent problematic alcohol use.

Self-regulation was an important influence, supporting the need to further investigate the developmental contribution of neurobehavioral disinhibition.

The Fraction of Cancer Attributable to Lifestyle and Environmental Factors in the UK in 2010

This supplement provides up-to-date estimates of the numbers (and percentages) of new cancer cases in the UK that are attributable to factors that have been established by international consensus as potentially avoidable causes of the disease. It therefore offers a useful guide to the relative importance of different preventive interventions.

Excluded from consideration are factors that, although known to be effective in reducing the risk of numerically important cancers, do not offer acceptable or practical preventive strategies at present. Early and multiple childbearing (to prevent breast cancer) and the widespread use of anti-androgen drugs (to prevent prostate cancer) come under this category. What remains is a limited number of important factors that can, at least to some extent, be affected by personal or political choices. The most important among these is continuation of the significant reduction in tobacco exposure. Next in importance are reductions in obesity and in heavy alcohol consumption, and certain other dietary changes. Each of these four main strategies for cancer control would also substantially reduce the burden of other non-communicable diseases, particularly cardiovascular, diabetic, renal and hepatic disease.

Whether, and to what extent, changes in these major causes of cancer can be achieved is another consideration. Thus, for example, although substantial progress has been made in reducing the number of young people who start smoking, and in helping those who smoke to escape their addiction in time to avoid most of the risk of premature death, tobacco still remains the most important avoidable cause of cancer, responsible for almost 20% of all cases of cancer (and, although this supplement does not quantify cancer mortality, for about 25% of all deaths from cancer, plus similar numbers of deaths from other diseases).

Taken together, the causative factors reviewed in this supplement account for an estimated 43% of all new cases of cancer in the UK (approximately 134 000 new cases in 2010), and about 50% of all cancer deaths. Most of these cases of cancer (excluding a few thousand due to the natural background of ionising radiation, or due to certain infections that are currently neither preventable nor treatable) could have been prevented by methods that would also prevent many premature deaths from other non-communicable disease. Over the past 40 years in the UK, the probability of death before the age of 70 years has been halved, and over the next few decades it could be halved again by continued improvements in the treatment of disease and by paying appropriate attention to the few major avoidable causes of disease. This supplement will help focus the attention of researchers, individuals and policy makers on the relative importance of the currently known causes of cancer.

Adolescents Living with a Parent Who Drives Under the Influence Are at Increased Risk for Driving Under the Influence Themselves

According to the National Survey on Drug Use and Health, an annual average1 of 932,000 16 to 17 year olds (11.5 percent) drove under the influence of alcohol or illicit drugs in the 12 months prior to the interview. Youths in this age group were more likely to drive under the influence if they lived with a mother or father who also had driven under the influence in the past year. These data suggest the importance of parents as role models in promoting children’s healthy behavior.

'Alcohol pricing and taxation policies': IFS still favours taxation over minimum pricing

The economics think-tank the Institute for Fiscal Studies (IFS) have published a new report on Alcohol pricing and taxation policies. It echoes many of the findings from a report last year in which it suggested minimum pricing would transfer further profits to industry and retailers, therefore favouring increased taxation.

The new report however suggests the current alcohol taxation system is not optimal and a "sensible starting point would be to tax all alcohols at an equivalent rate per unit. Such a change would require policy action at the EU level which the Government should pursue." > > > > Read More

Ethanol Exposure During Pregnancy Persistently Attenuates Cranially Directed Blood Flow in the Developing Fetus: Evidence from Ultrasound Imaging in a

Ethanol (EtOH) consumption during pregnancy can lead to fetal growth retardation, mental retardation, and neurodevelopmental delay. The fetal brain initiates neurogenesis and vasculogenesis during the second trimester, and depends on maternal-fetal circulation for nutrition and growth signals. We used high-resolution in vivo ultrasound imaging to test the hypothesis that EtOH interferes with fetal brain-directed blood flow during this critical developmental period.

Pregnant mice were lightly anesthetized on gestational day 12 with an isoflurane/oxygen mixture. We assessed the effect of single and repeated binge-like maternal EtOH exposures at 3 g/kg, administered by intragastric gavage or intraperitoneal injection, on maternal circulation and fetal umbilical, aortic, internal carotid, and middle cerebral arterial circulation.

Binge maternal EtOH exposure, regardless of exposure route, significantly reduced fetal arterial blood acceleration and velocity time integral (VTI), from umbilical to cerebral arteries, without a change in fetal heart rate and resistivity indices. Importantly a single maternal binge EtOH exposure induced persistent suppression of fetal arterial VTI for at least 24 hours. Repeated binge episodes resulted in a continuing and persistent suppression of fetal VTI. Qualitative assessments showed that maternal EtOH exposure induced oscillatory, nondirectional blood flow in fetal cerebral arteries. Maternal cardiac and other physiological parameters remained unaltered.

These data show that binge-type maternal EtOH exposure results in rapid and persistent loss of blood flow from the umbilical artery to the fetal brain, potentially compromising nutrition and the maternal/fetal endocrine environment during a critical period for neuron formation and angiogenesis in the maturing brain.

A Longitudinal Analysis of Circulating Stress-Related Proteins and Chronic Ethanol Self-Administration in Cynomolgus Macaques

Alcoholics have alterations in endocrine and immune functions and increased susceptibility to stress-related disorders. A longitudinal analysis of chronic ethanol intake on homeostatic mechanisms is, however, incompletely characterized in primates.

Plasma proteins (n = 60; Luminex) and hormones (adrenocorticotropic hormone [ACTH]; cortisol) were repeatedly measured in adult male cynomolgus monkeys (Macaca fascicularis, n = 10) during a 32-month experimental protocol at baseline, during induction of water and ethanol (4% w/v in water) self-administration, after 4 months, and after 12 months of 22-hour daily concurrent access to ethanol and water.

Significant changes were observed in ACTH, cortisol, and 45/60 plasma proteins: a majority (28/45) were suppressed as a function of ethanol self-administration, 8 proteins were elevated, and 9 showed biphasic changes. Cortisol and ACTH were greatest during induction, and correlations between these hormones and plasma proteins varied across the experiment. Pathway analyses implicated nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) and Janus kinase (JAK)/signal transducer and activator of transcription (STAT) as possible mediators of ethanol-induced effects on immune-related proteins in primates.

Chronic ethanol consumption in primates leads to an allostatic state of physiological compromise with respect to circulating immune- and stress-related proteins in NF-κB- and STAT/JAK-related pathways in correlation with altered endocrine activity.

Chronic Intermittent Ethanol Exposure and Its Removal Induce a Different miRNA Expression Pattern in Primary Cortical Neuronal Cultures

Increasing evidence indicates that repeated exposure to and withdrawal from alcohol can result in persistent molecular and cellular adaptations. One molecular adaptation that occurs is the regulation of gene expression, which is thought to lead to the functional alterations that characterize addiction: tolerance, dependence, withdrawal, craving, and relapse. MicroRNAs (miRNAs) have been recently identified as master regulators of gene expression through post-transcriptional regulation. However, the role of miRNAs in the neuroadaptations after alcohol removal has not yet been directly addressed.

We employed a chronic intermittent ethanol (CIE) model in primary cortical neuronal cultures to examine the global extent of differential miRNA expression using a TaqMan real-time PCR miRNA array.

Sixty-two miRNAs were differentially expressed after 10 days of CIE (CIE10) treatment (n = 42 with false discovery rate [FDR] < 0.05 and fold change > 2) and 5 days post-CIE (P5) treatment (n = 26) compared with untreated control values. Compared to CIE10, ethanol (EtOH) removal experience in P5 induced a distinct expression pattern, including 20 differentially expressed miRNAs, which did not exhibit a significant change at CIE10. The predicted target molecules of EtOH removal-induced miRNAs function mainly in the regulation of gene transcription, but also function in neuron differentiation, embryonic development, protein phosphorylation, and synaptic plasticity. Interestingly, some of the miRNAs differentially expressed 5 days after CIE treatment were found to cluster on chromosomes near CpG islands, suggesting that they share functional similarity by targeting alcohol-related genes.

Taken together, these results suggest a potential role of differentially expressed miRNAs in mediating EtOH removal-related phenotypes.

Prediction of the Risk of Comorbid Alcoholism in Schizophrenia by Interaction of Common Genetic Variants in the Corticotropin-Releasing Factor System

Stress plays a major role in the development of comorbid alcohol use disorder (AUD). In turn, AUD worsens the outcome of psychiatric patients with respect to global disease severity, social situation, and socioeconomic burden. Prediction of persons at risk for AUD is crucial for future preventive and therapeutic strategies.

To investigate whether genetic variants of the corticotropin-releasing factor system or their interaction influence the risk of developing AUD in chronic disease populations.

Genotype analysis comprising selected single-nucleotide polymorphisms within the CRHR1 and CRHBP genes in patients with schizophrenia and in a nonschizophrenic psychiatric disease control sample should allow the extraction of predictors of comorbid AUD. Gene expression (messenger RNA) analysis in peripheral blood mononuclear cells was performed to gain the first mechanistic insight.

An ideal setup for this study was the Göttingen Research Association for Schizophrenia Data Collection of schizophrenic patients, specifically intended to enable association of genetic information with quantifiable phenotypes in a phenotype-based genetic association study.

Patients A total of 1037 schizophrenic patients (Göttingen Research Association for Schizophrenia sample), 80 nonschizophrenic psychiatric disease controls as a small replicate sample, and a case-control study including 1141 healthy subjects.

Main Outcome Measures Association of CRHR1 and CRHBP genotypes with the following: (1) AUD; (2) a newly developed alcoholism severity score comprising 5 AUD-relevant variables; and (3) quantitative CRHR1 and CRHBP messenger .RNA expression.

An interaction of CRHR1 rs110402 and CRHBP rs3811939 predicts high risk of comorbid AUD in schizophrenic patients (odds ratio = 2.27; 95% confidence interval, 1.56-3.30; P < .001) as well as psychiatric disease controls (odds ratio = 4.02; 95% confidence interval, 0.95-17.05; P = .06) and leads to the highest CRHR1/CRHBP messenger RNA ratio (P = .02; dysbalanced stress axis).

The high predictive value of a genetic interaction within the stress axis for the risk of comorbid AUD may be used for novel preventive and individualized therapeutic approaches.

Inebriation, Drinking Motivations and Sexual Risk Taking Among Sexually Transmitted Disease Clinic Patients in St. Petersburg, Russia

We investigated whether inebriation was associated with having non-main partners and unprotected sex with non-main partners and whether drinking motivations were associated with sexual risk behaviors among patients attending an STD clinic in St Petersburg, Russia.

A cross-sectional behavior survey was applied to 362 participants between 2008 and 2009. Multivariate logistic regression was used for analysis.

At-risk drinking per Alcohol Use Disorders Identification Test (AUDIT-C) criteria (OR 2.5, 95% CI 1.4–4.4) was independently associated with having non-main sexual partners. Inebriation (OR 3.2, 95% CI 1.3–8.1) but not at-risk drinking or drinking prior to sex was associated with unprotected sex with non-main partners.

Among drinkers, the consumption of alcohol to facilitate sexual encounters (OR 2.7, 95% CI 1.6–4.5) was associated with having non-main sexual partners.

HIV prevention programs in Russia must address inebriation in addition to conventional patterns of problem drinking such as those measured by AUDIT-C and consider individuals’ motivations to drink that lead to sexual risk taking.

Medscape (Sweden) - Alcohol Abuse More Detrimental to the Female Brain

Alcohol abuse appears to be much more detrimental to the female brain than to the male brain, new research suggests. Investigators from the multidisciplinary Gothenburg Alcohol Research Project in Sweden found that after 4 years of excessive drinking, women experienced the same loss of serotonergic function that occurred in men who had been abusing alcohol for 12 years.

CBC.ca (Canada) - B.C. drunk-driving law could be overturned

The B.C. Supreme Court is expected to rule Wednesday on whether the province's tough new drunk-driving law violates constitutional rights. Described as the strictest impaired driving law in Canada, the B.C.

The Economist (Scotland) - The battle of the bottle

SATURDAY nights in most British cities are high-spirited, but in Glasgow they are the stuff of legend. Some 75,000 people stream through its streets, crowding into pubs and clubs. After the bouncers push their last all-but-senseless clients out of the door, and the last punch-up outside a chippy is dispersed by the Strathclyde police, pavements lie deserted under a dense coating of fag ends and glass shards. Over a thousand people will have been admitted to accident and emergency units.

Engagement with alcohol marketing and early brand allegiance in relation to early years of drinking

This study aimed to examine the relationship between measures of awareness to marketing and drinking among a sample of young people in New Zealand.

The sample consisted of 1302 males and 1236 females predominantly aged between 13 and 14 years and drawn from a number of schools in a metropolitan city. They were surveyed using a computer assisted telephone interview.

Regression analyses examined relationships between marketing (awareness of and engagement with a range of alcohol marketing channels) and reports of brand allegiance and drinking status, drinking frequency and quantity and future drinking intentions.

The results showed that awareness of each alcohol marketing channel increased the odds of being a drinker by 8%. Engagement with web-based marketing increased the odds of being a drinker by 98% while engagement with traditional marketing increased the odds by 51%. Brand allegiance increased the odds of being a drinker by 356% and increased the likelihood of non-drinkers reporting future drinking intentions (by 73%). Brand allegiance was also associated with more frequent alcohol consumption (1.65 times more drinking occasions per year) and 86% more alcohol consumed on a typical occasion.

The results suggest that, while exposure to all forms of marketing are associated with drinking by young people, measures of more active engagement, such as owning merchandise and downloading screensavers are stronger predictors of drinking. Having established a brand allegiance, at this early age, was related to not only drinking and future intentions to drink but also drinking patterns including consuming larger quantities.

Alcohol and Student Performance: Estimating the Effect of Legal Access

We consider the effect of legal access to alcohol on student achievement. We first estimate the effect using an RD design but argue that this approach is not well suited to the research question in our setting.

Our preferred approach instead exploits the longitudinal nature of the data, identifying the effect by measuring the extent to which a student’s performance changes after he gains legal access to alcohol, controlling flexibly for the expected evolution of grades as students make progress towards their degrees.

We find that students’ grades fall below their expected levels upon being able to drink legally, but by less than previously documented.

We also show that there are effects on women and that the effects are persistent.

Social Norm Influences on Evaluations of the Risks Associated with Alcohol Consumption: Applying the Rank-Based Decision by Sampling Model to Health J

The research first tested whether perceptions of other people's alcohol consumption influenced drinkers' perceptions of the riskiness of their own consumption. Second, the research tested how such comparisons are made—whether, for example, people compare their drinking to the ‘average’ drinker's or ‘rank’ their consumption amongst other people's. The latter untested possibility, suggested by the recent Decision by Sampling Model of judgment, would imply different cognitive mechanisms and suggest that information should be presented differently to people in social norm interventions.

Study 1 surveyed students who provided information on (a) their own drinking, (b) their perceptions of the distribution of drinking in the UK and (c) their perceived risk of various alcohol-related disorders. Study 2 experimentally manipulated the rank of ‘target’ units of alcohol within the context of units viewed simultaneously.

In both studies, the rank of an individual's drinking in a context of other drinkers predicted perceptions of developing alcohol-related disorders. There was no evidence for the alternative hypothesis that people compared with the average of other drinkers' consumptions. The position that subjects believed they occupied in the ranking of other drinkers predicted their perceived risk, and did so as strongly as how much they actually drank.

Drinking comparisons are rank-based, which is consistent with other judgments in social, emotional and psychophysical domains. Interventions should be designed to work with people's natural ways of information processing, through providing clients with information on their drinking rank rather than how their drinking differs from the average.
