Aims Research has shown that alcohol outcome expectancies are predictive of heavy alcohol consumption, which can lead to risky behavior. The purpose of the present study was to assess the incidence of various low-risk social behaviors while drinking among college students. Such social behaviors may later be regretted (referred to as regrettable social behaviors) and include electronic and in-person communications. Methods College students (N = 236) completed measures of alcohol outcome expectancies and regrettable social behaviors. Results Regrettable social behaviors were reported by 66.1% of participants, suggesting that they may occur at a much higher rate than more serious drinking-related consequences (e.g. drinking and driving, violence, etc.). Expectancies for social facilitation predicted regrettable social behavior. Further, this relationship was mediated by amount of alcohol consumed. Conclusion Given the high incidence, regrettable social behaviors may be effective targets in alcohol prevention programming. PMID:25820611

Background: The present study explores the role of having rules about alcohol, parental norms about early alcohol use, and parental alcohol use in the development of adolescents' drinking behavior. It is assumed that parental norms and alcohol use affect the rules parents have about alcohol, which in turn prevents alcohol use by adolescent…

Multiple event-level methodology was used to examine the relation between risky sexual behavior and alcohol use among sexually active, heavy drinking college students (N = 221). Using a structured timeline follow-back interview, participants reported their sexual, alcohol, and drug use behaviors over a 3-month period. Over 2,700 vaginal or anal sexual events were reported from 177 participants. Overall, condom use was not associated with heavy or non-heavy alcohol consumption among those reporting both sexual events concurrent with heavy drinking and when no alcohol was consumed. Results from multilevel regression analyses revealed a more complex pattern. Among women, but not men, less condom use was associated with steady versus casual sexual partners, but partner type interacted with alcohol consumption such that less condom use occurred when heavy drinking preceded sex with steady partners. At the event-level, alcohol consumption among heavy drinking college students leads to risky sexual behavior but the relation differs by gender and partner type.

Alcohol use disorder (AUD) is heritable, but the genetic basis for this disease remains poorly understood. Although numerous gene variants have been associated with AUD, these variants account for only a small fraction of the total risk. The idea of inheritance of acquired characteristics, i.e. “epigenetic inheritance,” is re-emerging as a proven adjunct to traditional modes of genetic inheritance. We hypothesized that alcohol drinking and neurobiological sensitivity to alcohol are influenced by ancestral alcohol exposure. To test this hypothesis, we exposed male mice to chronic vapor ethanol or control conditions, mated them to ethanol-naïve females, and tested adult offspring for ethanol drinking, ethanol-induced behaviors, gene expression, and DNA methylation. We found that ethanol-sired male offspring had reduced ethanol preference and consumption, enhanced sensitivity to the anxiolytic and motor-enhancing effects of ethanol, and increased Bdnf expression in the ventral tegmental area (VTA) compared to control-sired male offspring. There were no differences among ethanol- and control-sired female offspring on these assays. Ethanol exposure also decreased DNA methylation at the BdnfÆpromoter of sire's germ cells and hypomethylation was maintained in the VTA of both male and female ethanol-sired offspring. Our findings show that paternal alcohol exposure is a previously unrecognized regulator of alcohol drinking and behavioral sensitivity to alcohol in male, but not female, offspring. Paternal alcohol exposure also induces epigenetic alterations (DNA hypomethylation) and gene expression changes that persist in the VTA of offspring. These results provide new insight into the inheritance and development of alcohol drinking behaviors. PMID:24896617

Alcohol attitudes are often considered an important predecessor of drinking behavior, although the literature is equivocal. Lately, attention has turned to enhancing positive cognitions on alcoholic-free drinks to discourage heavy drinking. The current study was the first to longitudinally examine associations between attitudes towards binge drinking and alcohol-free drinks and binge drinking behavior in a cross-lagged path model in Mplus. Participants were 293 adolescents (131 boys, M(age)=16.1 years) who filled in two online questionnaires with a six-month interval. Binge drinking behavior and attitudes towards binge drinking and alcohol-free drinks were all significantly correlated at both waves. The multivariate model, however, showed that only higher levels of binge drinking at T1 were prospectively related to more positive binge drinking attitudes at T2, and not vice versa. Analyses were controlled for sex, educational level, and age. Findings discard the Theory of Planned Behavior, but rather seem consistent with the Theory of Cognitive Dissonance, i.e., adolescents may adapt their cognitions to their behavior. More longitudinal research with several time points and over a longer period of time is needed to further examine the development of attitudes and drinking behavior.

The aim of this study was to evaluate the prevalence, behavioral patterns and correlates of regular alcohol drinking in high school students. This cross-sectional study involved the completion of a modified version of "Health Behavior in School Age Children" (HBSC 1997/1998) questionnaire by 4,153 grade 9-11 students from 26 randomly selected high schools in Istanbul. Chi-square test, Spearman correlation test and forward stepwise multiple logistic regression model were used for statistical analyses as appropriate. Overall, 61% of students were experimental drinkers, and 46% of the students were current drinkers. There was a significant difference between female and male students with respect to reporting current alcohol drinking at grade 9 and 11 (p > 0.05 for each comparison). Regular drinking was reported by 6% of students. Male students were more likely than female students to report regular drinking at each grade (p < 0.01 for each comparison). Nineteen percent of the students reported that they had been really drunk at least once during their lifetime. Malestudents were more likely than female students to report an occasion of drunkenness at each grade (p < 0.05 for each comparison). All types of drinking behavior rates tended to increase across grades for both genders (p < 0.05 for each comparison). In logistic regression analysis the following were all independently associated with regular drinking: being in grade 11, smoking cigarettes currently, lifetime drug use, bullying others, being sexually active, playing computer games > or = 4 h/week, exercising < or = 1 h/week, spending > or = four evenings with friends, at ease in talking to same gender friends, tiredness in the morning, perceived as good-looking/beautiful, higher educational level of the mother and perceived poor academic achievement. The results of this study showed that alcohol consumption is prevalent among high school students. There is therefore a need for school-based alcohol prevention

Thirty nonalcoholic young (18 to 30 years) males with extensive multigenerational family histories of male alcoholism and 29 age-matched, family history-negative controls completed a variety of trait personality questionnaires, participated in a competitive stress task (while sober and alcohol-intoxicated), and were assessed for self-report and laboratory drinking behavior. Low academic achievement, disinhibited personality (as measured by the P Scale of the Eysenck Personality Questionnaire), and sensitivity to alcohol reinforcement were significant and powerful independent predictors of self-report (approximate R2 = 0.40, p < 0.0001) and laboratory (approximate R2 = 0.20, p < 0.0001) drinking behavior. There seemed to be some specificity with respect to the facets of drinking behavior accounted for by each independent variable: low academic achievement and sensitivity to alcohol reinforcement were more related to quantity of alcohol consumption and frequency of excessive consumption, whereas psychoticism was more related to self-reported negative consequences with alcohol. A cluster analysis on three identified correlates of drinking behavior indicated that the two experimental groups could be more accurately subdivided into three homogeneous types. Multigenerational family history males were disproportionately represented in two of these groups: one characterized by enhanced sensitivity to alcohol reinforcement and the other characterized by high psychoticism scores and alcohol-related problems.

Sigma-1 receptor (Sig-1R) has been proposed as a novel therapeutic target for drug and alcohol addiction. We have shown previously that Sig-1R agonists facilitate the reinforcing effects of ethanol and induce binge-like drinking, while Sig-1R antagonists on the other hand block excessive drinking in genetic and environmental models of alcoholism, without affecting intake in outbred non-dependent rats. Even though significant progress has been made in understanding the function of Sig-1R in alcohol reinforcement, its role in the early and late stage of alcohol addiction remains unclear. Administration of the selective Sig-1R antagonist BD-1063 dramatically reduced the acquisition of alcohol drinking behavior as well as the preference for alcohol in genetically selected TSRI Sardinian alcohol preferring (Scr:sP) rats; the treatment had instead no effect on total fluid intake, food intake or body weight gain, proving selectivity of action. Furthermore, BD-1063 dose-dependently decreased alcohol-seeking behavior in rats trained under a second-order schedule of reinforcement, in which responding is maintained by contingent presentation of a conditioned reinforcer. Finally, an innate elevation in Sig-1R protein levels was found in the nucleus accumbens of alcohol-preferring Scr:sP rats, compared to outbred Wistar rats, alteration which was normalized by chronic, voluntary alcohol drinking. Taken together these findings demonstrate that Sig-1R blockade reduces the propensity to both acquire alcohol drinking and to seek alcohol, and point to the nucleus accumbens as a potential key region for the effects observed. Our data suggest that Sig-1R antagonists may have therapeutic potential in multiple stages of alcohol addiction.

Purpose To examine short-term consequences associated with consuming alcohol and energy drinks compared with consuming alcohol without energy drinks. Methods A longitudinal measurement-burst design (14-day bursts of daily surveys in four consecutive college semesters) captured both within-person variation across occasions and between-person differences across individuals. The analytic sample of late adolescent alcohol users included 4,203 days with alcohol use across up to four semesters per person from 508 college students. Results Adding energy drink use to a given day with alcohol use was associated with an increase in number of alcoholic drinks, a trend toward more hours spent drinking, elevated estimated blood alcohol content (eBAC), a greater likelihood of subjective intoxication, and more negative consequences of drinking that day. After controlling for eBAC, energy drink use no longer predicted subjective intoxication but was still associated with a greater number of negative consequences. Conclusions The consumption of energy drinks may lead to increases in alcohol consumption and, after controlling for eBAC, negative consequences. Use of energy drinks plus alcohol represents an emerging threat to public health. PMID:24309196

Alcoholic individuals often are assumed to deny personal responsibility for their alcholism and to assign causation to external situational factors. To evaluate this assumption, 20 alchololics and 14 nonalcoholics made causal attributions for a recent personal drinking episode and for the drinking behavior of three target individuals (an abstinent alcoholic, a nonabstinent alcololic, and a nonalcoholic). Results showed that both alcoholic and non-alcoholic subjects tended to make external attributions for their own drinking behavior. Subjects' attributons for the target individuals depended on bot the targest' and subjects' drinking histories. The results are discussed in terms of their relevance to models of alcoholism and to actor-observer differences in casual attribution processes.

Alcohol expectancies have been associated with drinking behaviors among college students. Few studies, however, have focused on researcher-labeled ''positive'' and ''negative'' expectancies as well as the valuations (i.e., desirability) of these expectancies. Moreover, research on the correlates of heavy drinking among female college athletes…

Prenatal alcohol exposure can have serious and permanent adverse effects. The developing brain is the most vulnerable organ to the insults of prenatal alcohol exposure. A behavioral phenotype of prenatal alcohol exposure including conduct disorders is also described. This study on a sample of Brazilian adolescents convicted for criminal behavior aimed to evaluate possible clinical features of Fetal Alcohol Syndrome (FAS). These were compared to a control group of school adolescents, as well as tested for other environmental risk factors for antisocial behavior. A sample of 262 institutionalized male adolescents due to criminal behavior and 154 male students aged between 13 and 21 years comprised the study population. Maternal use of alcohol was admitted by 48.8% of the mothers of institutionalized adolescents and by 39.9% of the school students. In this sample of adolescents we could not identify individual cases with a clear diagnosis of FAS, but signs suggestive of FASD were more common in the institutionalized adolescents. Social factors like domestic and family violence were frequent in the risk group, this also being associated to maternal drinking during pregnancy. The inference is that in our sample, criminal behavior is more related to complex interactions between environmental and social issues including prenatal alcohol exposure.

Dopamine and serotonin (5-HT) in the nucleus accumbens (ACC) and ventral tegmental area of the mesoaccumbens reward pathways have been implicated in the mechanisms underlying development of alcohol dependence. We used a C57BL/6J mouse model with increased voluntary alcohol-drinking behavior by exposing the mice to alcohol vapor for 20 consecutive days. In the alcohol-exposed mice, the expression of 5-HT(2C) receptor mRNA increased in the ACC, caudate nucleus and putamen, dorsal raphe nucleus (DRN), hippocampus and lateral hypothalamus, while the protein level of 5-HT(2C) receptor significantly increased in the ACC. The expression of 5-HT(7) receptor mRNA increased in the ACC and DRN. Contents of 5-HT decreased in the ACC shell (ACC(S) ) and DRN of the alcohol-exposed mice. The basal extracellular releases of dopamine (DA) and 5-HT in the ACC(S) increased more in the alcohol-exposed mice than in alcohol-naïve mice. The magnitude of the alcohol-induced ACC(S) DA and 5-HT release in the alcohol-exposed mice was increased compared with the control mice. Intraperitoneal (i.p.) administration or local injection into ACC(S) of the 5-HT(2C) receptor antagonist, SB-242084, suppressed voluntary alcohol-drinking behavior in the alcohol-exposed mice. But the i.p. administration of the 5-HT(7) receptor antagonist, SB-258719, did not have significant effects on alcohol-drinking behavior in the alcohol-exposed mice. The effects of the 5-HT(2C) receptor antagonist were not observed in the air-exposed control mice. These results suggest that adaptations of the 5-HT system, especially the upregulation of 5-HT(2C) receptors in the ACC(S) , are involved in the development of enhanced voluntary alcohol-drinking behavior.

This paper explores the connection between alcohol-related mortality, drinking behavior, and macroeconomic conditions in Finland using both aggregate and microlevel data from recent decades. The aggregate data reveal that an improvement in economic conditions produces a decrease in alcohol-related mortality. Microlevel data show that alcohol consumption increases during economic expansion while the probability of being a drinker remains unchanged. This demonstrates that alcohol-related mortality and self-reported alcohol consumption may be delinked in the short-run business cycle context. One explanation for this paradox is that most harmful forms of drinking are not captured in survey-based data used to study the effect of macroeconomic conditions on alcohol consumption. Our evidence does not overwhelmingly support the conclusions reported for the United States that temporary economic downturns are good for health.

Social learning mechanisms, such as descriptive norms for drinking behavior (norms) and positive alcohol expectancies (PAEs), play a major role in college student alcohol use. According to the principle of reciprocal determinism (Bandura, 1977), norms and PAEs should be reciprocally associated with alcohol use, each influencing one another over time. However, the nature of these prospective relationships for college students is in need of further investigation. This study provided the first examination of the unique reciprocal associations among norms, PAEs, and drinking together in a single model. PAEs become more stable with age, whereas norms are likely to be more dynamic upon college entry. Thus, we hypothesized that alcohol use would show stronger reciprocal associations with norms than with PAEs for college students. Students (N = 557; 67% women) completed online measures of PAEs, norms, and quantity and frequency of alcohol use in September of their first (T1), second (T2), and third (T3) years of college. Reciprocal associations were analyzed using a cross-lagged panel design. PAEs had unidirectional influences on frequency and quantity of alcohol use, with no prospective effects from alcohol use to PAEs. Reciprocal associations were observed between norms and alcohol use, but only for quantity and not for frequency. Specifically, drinking quantity prospectively predicted quantity norms and quantity norms prospectively predicted drinking quantity. This effect was observed across both years in the model. These findings support the reciprocal determinism hypothesis for norms but not for PAEs in college students and may help to inform norm-based interventions.

Background Cabergoline is an ergotamine derivative that increases the expression of glial cell line-derived neurotrophic factor (GDNF) in vitro. We recently showed that GDNF in the ventral tegmental area (VTA) reduces the motivation to consume alcohol. We therefore set out to determine whether cabergoline administration decreases alcohol-drinking and -seeking behaviors via GDNF. Methods Reverse transcription polymerase chain reaction (RT-PCR) and Enzyme-Linked ImmunoSorbent Assay (ELISA) were used to measure GDNF levels. Western blot analysis was used for phosphorylation experiments. Operant self-administration in rats and a two-bottle choice procedure in mice were used to assess alcohol-drinking behaviors. Instrumental performance tested during extinction was used to measure alcohol-seeking behavior. The [35S]GTPγS binding assay was used to assess the expression and function of the dopamine D2 receptor (D2R). Results We found that treatment of the dopaminergic-like cell line SH-SY5Y with cabergoline and systemic administration of cabergoline in rats resulted in an increase in GDNF level and in the activation of the GDNF pathway. Cabergoline treatment decreased alcohol-drinking and -seeking behaviors including relapse, and its action to reduce alcohol consumption was localized to the VTA. Finally, the increase in GDNF expression and the decrease in alcohol consumption by cabergoline were abolished in GDNF heterozygous knockout mice. Conclusions Together, these findings suggest that cabergoline-mediated upregulation of the GDNF pathway attenuates alcohol-drinking behaviors and relapse. Alcohol abuse and addiction are devastating and costly problems worldwide. This study puts forward the possibility that cabergoline might be an effective treatment for these disorders. PMID:19232578

We sought to 1) describe the settings or groups of settings where men who have sex with men (MSM) consume alcohol in 16 U.S. metropolitan statistical areas (MSA); and 2) investigate whether certain drinking settings or groups of settings are associated with higher levels of alcohol consumption, problem drinking, and sexual risk behavior. Latent class analysis was used to develop our measure of drinking settings. The final latent class model consisted of four distinct classes which captured the typical settings where MSM consumed alcohol: “home” “social,” “bar/social,” and “general” drinkers (i.e., drinks in all settings). Regression models showed that “general” drinkers were more likely than “social” drinkers to engage in frequent heavy drinking. Compared to `social' drinkers, general drinkers were also more likely to engage in unprotected anal intercourse (UAIMP) and UAIMP with men met in bars and other venues (e.g., private parties, bath houses) while intoxicated. Assessment of drinking settings may be a means of identifying MSM who are at greater risk for frequent, heavy drinking and related sexual risk behavior. PMID:23261495

How does adolescent organizational membership in general, and simultaneous membership in distinct types of organizations in particular, impact drinking behavior? While past studies have focused either on the learning effect of involvement with gangs or on the constraining influence of conventional organizations on adolescent problem behavior, we explore the possibility that conventional school clubs can serve as socializing opportunities for existing gang members to engage in drinking behavior with non-gang club members. Using the Add Health data, we show that gang members drink more often, and engage in more binge drinking, than non-members. More importantly, individuals who are members of both gangs and school clubs drink alcohol at greater levels than those who are solely involved in gangs. In addition, non-gang adolescents who are co-members with gang members in the same school club are more likely to drink alcohol than non-members. This result has important implications for understanding the role of organizations in adolescent behavior and suggests that the study of delinquent behaviors would benefit from devoting more attention to individuals who bridge distinct types of organizations.

Although heavy episodic drinkers are at risk to experience alcohol-related consequences, studies show that a large percentage of student drinkers do not experience problems as a result of their drinking. The present study was a more in-depth examination of factors beyond just drinking quantity and frequency to explain why students experience consequences. The current research examined the relationship between the use of protective behaviors, alcohol use, and alcohol related consequences, as well as the relationship between attitudinal and cognitive predictors of engaging in protective behaviors when drinking. We hypothesized there would be a significant direct effect of protective behaviors on consequences after taking into account the effect of alcohol use and that cognitive predictors, including perceived self-efficacy, perceived effectiveness, and subjective norm, would be associated with the attitude and frequency of engaging in protective behaviors. Results supported both hypotheses, indicating good model fit for all models and significant paths between constructs (p's<.05). These findings extend the literature on protective behaviors by providing insight as to their utility in preventing harm and why students choose to engage in these behaviors. Implications for interventions are also discussed.

According to information-processing models of alcohol use, alcohol expectancies constitute representations in long-term memorythat may be activated in the presence of drinking-related cues, thereby influencing alcohol consumption. A fundamental implication of this approach is that primed expectancies should affect drinking only for those individuals who possess the specific expectancies primed. To test this notion, in the present study, participants were initially assessed on three distinct domains of positive alcohol expectancies. Approximately one week later, they completed an ad libitum drinking study during which only a single expectancy domain (sociability) was primed in the experimental condition. Consistent with predictions, following exposure to sociability primes, but not control primes, individuals with stronger expectancies that alcohol would enhance sociability uniquely showed increased placebo consumption of nonalcoholic beer. These results, which demonstrate the moderating role of compatibility between the specific content of primes and that of underlying expectancies, offer new, direct support for memory network-based models of drinking behavior.

This study examined protective behavioral strategies (PBS) as a moderator of the relationship between impulsive sensation seeking and binge drinking and alcohol-related consequences in a sample of high school seniors (N=346). Hierarchical regression analyses indicated that impulsive sensation seeking was a significant predictor of binge drinking and alcohol-related consequences and that PBS moderated these relationships. Specifically, manner of drinking moderated the relationships such that among students with high impulsive sensation seeking, those using strategies related to how they drink (e.g. avoiding rapid and excessive drinking) reported lower levels of binge drinking and alcohol-related consequences than those using fewer of these strategies. Clinical implications are discussed including using personality-targeted interventions that equip high impulsive sensation seeking adolescents with specific strategies to reduce binge drinking and alcohol-related consequences.

It is widely accepted that stress, anxiety, depression and alcohol abuse-related disorders are in large part controlled by corticotropin-releasing factor (CRF) receptors. However, evidence is accumulating that some of the actions on these receptors are mediated not by CRF, but by a family of related Urocortin (Ucn) peptides Ucn1, Ucn2 and Ucn3. The initial narrow focus on CRF as the potential main player acting on CRF receptors appears outdated. Instead it is suggested that CRF and the individual Ucns act in a complementary and brain region-specific fashion to regulate anxiety-related behaviors and alcohol consumption. This review, based on a symposium held in 2011 at the research meeting on "Alcoholism and Stress" in Volterra, Italy, highlights recent evidence for regulation of these behaviors by Ucns. In studies on stress and anxiety, the roles of Ucns, and in particular Ucn1, appear more visible in experiments analyzing adaptation to stressors rather than testing basal anxiety states. Based on these studies, we propose that the contribution of Ucn1 to regulating mood follows a U-like pattern with both high and low activity of Ucn1 contributing to high anxiety states. In studies on alcohol use disorders, the CRF system appears to regulate not only dependence-induced drinking, but also binge drinking and even basal consumption of alcohol. While dependence-induced and binge drinking rely on the actions of CRF on CRFR1 receptors, alcohol consumption in models of these behaviors is inhibited by actions of Ucns on CRFR2. In contrast, alcohol preference is positively influenced by actions of Ucn1, which is capable of acting on both CRFR1 and CRFR2. Because of complex distribution of Ucns in the nervous system, advances in this field will critically depend on development of new tools allowing site-specific analyses of the roles of Ucns and CRF.

Alcohol use has been implicated as a risk factor for sexual negative consequences, such as unprotected sexual intercourse. The present research was conducted to examine the relationship between drinking protective behavioral strategies and consensual sex-related alcohol negative consequences, and whether this relationship varied by gender. Additionally, typical number of drinks during sexual behavior was evaluated as a potential mediator of this association. Heavy drinking, sexually active college students (N = 297, 50.2% female) completed self-report measures of drinking protective behavioral strategies, alcohol consumption, and sex-related alcohol negative consequences. Findings indicated that women who used drinking protective behavioral strategies more frequently were less likely to experience sex-related alcohol negative consequences whereas this relationship was not significant for men. For women, this relationship was mediated by the typical number of drinks consumed during sexual behavior. The current research demonstrates that use of drinking protective behavioral strategies is related to a reduction in women's sex-related risks when drinking. Findings are discussed in terms of alcohol myopia theory. Implications for interventions aimed to reduce higher risk sexual behavior among college students are discussed. PMID:20565149

The aim of this research was to explore the increasingly popular Dutch health phenomenon of 'gathering in private peer group settings (barracks)', with a focus on the prevalence and characteristics of barracks, alcohol consumption, and other (risk) behaviors of their visitors. Three studies were conducted. The first consisted of field research in which 51 barracks were visited and group-interviews were held. The second was an Internet study in which 442 barracks' websites were analyzed using content analysis. The third consisted of a questionnaire completed by 1457 adolescents, aged 15-17, in order to explore differences in behavior between barracks visitors and non-visitors. There was wide variation in barracks' characteristics and culture. Barracks' members and visitors also organize diverse activities that are publicly shown on the websites. Barracks are associated with various legal issues, such as alcohol sales to minors, lack of parental supervision, and illicit drug use. Barracks' visitors drink alcohol more frequently, drink more alcohol per occasion (up to fifteen bottles of beer a night), and have been drunk more frequently than non-visitors. Policymakers must be aware of the barracks phenomenon and use their powers in adjacent political and legal areas (such as in binge drinking, illicit drug use, and public safety) to intervene and create solid, responsible, and tailor-made policies.

The use of mice in alcohol research provides an excellent model system for a better understanding of the genetics and neurobiology of alcohol addiction. Almost 60 years ago, alcohol researchers began to test strains of mice for alcohol preference and intake. In particular, various voluntary alcohol drinking paradigms in the home cage were developed. In mouse models of voluntary oral alcohol consumption, animals have concurrent access to water and either one or several concentrated alcohol solutions in their home cages. Although these models have high face validity, many experimental conditions require a more precise monitoring of alcohol consumption in mice in order to capture the role of specific strains or genes, or any other manipulation on alcohol drinking behavior. Therefore, we have developed a fully automated, highly precise monitoring system for alcohol drinking in mice in the home cage. This system is now commercially available. We show that this drinkometer system allows for detecting differences in drinking behavior (i) in transgenic mice, (ii) following alcohol deprivation, and (iii) following stress applications that are usually not detected by classical home-cage drinking paradigms. In conclusion, our drinkometer system allows disturbance-free and high resolution monitoring of alcohol drinking behavior. In particular, micro-drinking and circadian drinking patterns can be monitored in genetically modified and inbred strains of mice after environmental and pharmacological manipulation, and therefore this system represents an improvement in measuring behavioral features that are of relevance for the development of alcohol use disorders.

Background The regulation of alcohol outlet density has been considered as a potential means of reducing alcohol consumption and related harms among underage youth. Whereas prior studies have examined whether alcohol outlet density was associated with an individual’s alcohol consumption and related harms, this study examines whether it is related to the co-occurrence, or clustering, of these behaviors within geographic areas, specifically census tracts. Methods The Enforcing Underage Drinking Laws Randomized Community Trial provided cross-sectional telephone survey data in 2006 and 2007 from 10,754 youth aged 14–20 from 5 states residing in 1556 census tracts. The alternating logistic regression approach was used to estimate pairwise odds ratios between responses from youth residing in the same census tract and to model them as a function of alcohol outlet density. Results Riding with a drinking driver, making an alcohol purchase attempt and making a successful alcohol purchase attempt clustered significantly within census tracts with the highest off-premise alcohol outlet density while frequent drinking clustered within census tracts with the greatest on-premise density. Driving after drinking and experiencing non-violent alcohol-related consequences clustered marginally within census tracts with the greatest on-premise and off-premise alcohol outlet density, respectively. Conclusions Although youth primarily receive alcohol from social sources, commercial alcohol access is geographically concentrated within census tracts with the greatest off-premise outlet density. A potentially greater concern is the clustering of more frequent drinking and drinking and driving within census tracts with the greatest on-premise outlet density which may necessitate alternative census tract level initiatives to reduce these potentially harmful behaviors.

According to dual-process models, excessive alcohol use emerges when response inhibition ability is insufficient to inhibit automatic impulses to drink alcohol. This study examined whether strengthening response inhibition for alcohol-related cues decreases alcohol intake. Fifty-two heavy drinking students were randomly assigned to one of two conditions: In the beer/no-go condition, participants performed a go/no-go task that consistently paired alcohol-related stimuli with a stopping response, to increase response inhibition for alcohol-related stimuli. In the beer/go condition, in contrast, participants were always required to respond to alcohol-related stimuli during the go/no-go task. Before and after the go/no-go manipulation, we measured weekly alcohol intake and implicit attitudes toward alcohol. In addition, we measured alcohol consumption during a taste test immediately after the go/no-go manipulation. Following the manipulation, participants in the beer/no-go condition demonstrated significantly increased negative implicit attitudes toward alcohol, and a significant reduction in weekly alcohol intake, while participants in the beer/go condition showed a non-significant increase in implicit positive attitudes toward alcohol and a significant increase in weekly alcohol intake. This study demonstrates that repeatedly stopping prepotent responses toward alcohol-related stimuli can be an effective strategy to reduce excessive alcohol use.

Background There has been a dramatic rise in the consumption of alcohol mixed with energy drinks (AmED) in young people. AmEDs have been implicated in risky drinking practices and greater accidents and injuries have been associated with their consumption. Despite the increased popularity of these beverages (e.g., Red Bull and vodka), there is little laboratory research examining how the effects of AmED differ from alcohol alone. This experiment was designed to investigate if the consumption of AmED alters neurocognitive and subjective measures of intoxication compared with the consumption of alcohol alone. Methods Participants (n=56) attended one session where they were randomly assigned to receive one of four doses (0.65 g/kg alcohol, 3.57 ml/kg energy drink, AmED or a placebo beverage). Performance on a cued go/no-go task was used to measure the response of inhibitory and activational mechanisms of behavioral control following dose administration. Subjective ratings of stimulation, sedation, impairment and level of intoxication were recorded. Results Alcohol alone impaired both inhibitory and activational mechanisms of behavioral control, as evidenced by increased inhibitory failures and increased response times compared to baseline performance. Coadministration of the energy drink with alcohol counteracted some of the alcohol-induced impairment of response activation, but not response inhibition. For subjective effects, alcohol increased ratings of stimulation, feeling the drink, liking the drink, impairment and level of intoxication and alcohol decreased the rating of ability to drive. Coadministration of the energy drink with alcohol increased self-reported stimulation, but resulted in similar ratings of the other subjective effects as when alcohol was administered alone. Conclusions An energy drink appears to alter some of alcohol’s objective and subjective impairing effects, but not others. Thus AmEDs may contribute to a high risk scenario for the drinker

Alcohol consumption, a risk factor for HIV transmission in sub-Saharan Africa, is considered high in Uganda. The study was conducted to determine whether sex-related expectations about the effects of alcohol help explain the association between alcohol use and risky sexual behaviors in a population-based sample of adults in Kampala. A two-stage sampling procedure was used to identify residents in one division of Kampala for a cross-sectional study. Associations between alcohol use (current and higher-risk drinking) and high-risk sexual behaviors (multiple regular partners and casual sex) were tested. Final models included a sex-related alcohol outcome expectancy (AOE) summary score. In age-sex-adjusted models, having multiple regular partners was associated with current drinking (Odds Ratio (OR)=2.76, 95% Confidence Intervals (CI)=1.15, 6.63) and higher-risk drinking (OR=3.35, 95%CI=1.28,8.71). Associations were similar but not statistically significant for having a causal sex partner. Sex-related AOE were associated with both alcohol use and high-risk sexual behavior and attenuated relationships between multiple regular partners and both current drinking (OR=1.94, 95%CI=0.57,6.73) and higher-risk drinking (OR=2.44, 95%CI=0.68,8.80). In this setting sexual behaviors related with alcohol consumption were explained, in part, by sex-related expectations about the effects of alcohol. These expectations could be an important component to target in HIV education campaigns. PMID:26315308

Puerarin, daidzin, and daidzein are 3 major isoflavonoid compounds isolated from Pueraria lobata, an edible vine used widely in China for various medicinal purposes. We studied the antiinebriation and the antidipsotropic effects of these antioxidants in rats. Daidzin and daidzein shortened alcohol-induced sleep time (loss of righting reflex) in rats that were given ethanol intragastrically but not in those given ethanol intraperitoneally. When daidzin was given to animals intragastrically with the ethanol solution, the blood alcohol concentration (BAC) was found to peak later and be lower than in control rats that were given only the ethanol solution. BACs also receded more slowly if daidzin was fed to the animals. None of the 3 isoflavonoid compounds administered orally affected liver alcohol dehydrogenase or aldehyde dehydrogenase activities, as was reported for intraperitoneal administration. Further experiments indicated that the suppression of the BAC by daidzin was due mainly to delay of stomach emptying. All 3 compounds suppressed voluntary alcohol consumption in alcohol-preferring rats. The decrease in alcohol consumption was accompanied by an increase in water intake, so that the total volume of liquid consumed daily remained unchanged. Daily food consumption and body weight gain were not affected. Alcohol preference returned to baseline levels after the isoflavonoids were discontinued. We postulate that the suppression of alcohol reinforcement produced by these compounds is mediated centrally in the brain reward pathway.

Background Global association and experimental studies suggest that alcohol use may increase sexual behavior that poses risk for exposure to sexually-transmitted infections (STI) among heterosexual men and women. However, results from longitudinal and daily recall studies exploring the co-occurrence of alcohol use with various sexual risk outcomes in more naturalistic contexts have been mixed, and the bulk of this research has focused on college students. Methods The current study enrolled heavy-drinking emergency department (ED) patients and used a cross-sectional, 30-day Timeline Followback (TLFB) method to examine the daily co-occurrence between alcohol use and three sexual behavior outcomes: Any sex, unprotected intercourse (UI), and UI with casual partners (vs. protected intercourse [PI] with casual partners, or UI/PI with steady partners). Results Results indicated that increasing levels of alcohol use on a given day increased the odds of engaging in any sexual activity and that heavy drinking (but not very heavy drinking) on a given day was associated with an increased odds of engaging in UI with either steady or casual partners. However, day-level alcohol use was not associated with an increased odds of UI with casual partners. Conclusions These findings suggest that alcohol may play an important role in increasing risk for HIV/STIs among heterosexuals, and support the continued need to target heavy drinking in sex risk reduction interventions. However, our results also suggest that alcohol may not universally result in unprotected sex with casual partners, a behavior posing perhaps the highest risk for HIV/STI transmission. PMID:25962789

Background The contribution of epigenetic factors, such as histone acetylation and DNA methylation, to the regulation of alcohol drinking behavior has been increasingly recognized over the last several years. GADD45b is a protein demonstrated to be involved in DNA demethylation at neurotrophic factor gene promoters, including at Brain-derived neurotrophic factor (Bdnf) which has been highly implicated in alcohol drinking behavior. Methods DNA methyltransferase-1 (Dnmt1), 3a, and 3b, and Gadd45a, b, and g mRNA were measured in the nucleus accumbens (NAc) and ventral tegmental areas (VTA) of high ethanol consuming C57BL/6J (C57) and low alcohol consuming DBA/2J (DBA) mice using qRT-PCR. In the NAc GADD45b protein was measured via immunohistochemistry and Bdnf9a mRNA using in situ PCR. Bdnf9a promoter histone H3 acetylated at lysines 9 and 14 (H3K9,K14ac) was measured using chromatin immunoprecipitation, and 5-methylcytosine (5MC) and 5-hydroxymethylcytosine (5HMC) using methylated DNA immunoprecipitation. Alcohol drinking behavior was evaluated in Gadd45b haplodeficient (+/−) and null mice (−/−) utilizing drinking in the dark (DID) and 2-bottle free-choice paradigms. Results C57 mice had lower levels of Gadd45b and g mRNA and GADD45b protein in the NAc relative to the DBA strain. C57 mice had lower NAc shell Bdnf9a mRNA levels, Bdnf9a promoter H3K9,K14ac, and higher Bdnf9a promoter 5HMC and 5MC. Acute ethanol increased GADD45b protein, Bdnf9a mRNA, and histone acetylation and decreased 5HMC in C57 mice. Gadd45b +/− mice displayed higher drinking behavior relative to wild-type littermates in both DID and 2-bottle free-choice paradigms. Conclusions These data indicate the importance of the DNA demethylation pathway and its interactions with histone post-translational modifications in alcohol drinking behavior. Further, we suggest that lower DNA demethylation protein GADD45b levels may affect Bdnf expression possibly leading to altered alcohol drinking behavior

IMPORTANCE Alcohol is the most common drug among youth and a major contributor to morbidity and mortality worldwide. Billions of dollars are spent annually marketing alcohol. OBJECTIVE To examine the reach of television alcohol advertising and its effect on drinking among underage youth. DESIGN, SETTING, AND PARTICIPANTS Longitudinal telephone- and web-based surveys conducted in 2011 and 2013 involving 2541 US adolescents 15 to 23 years of age at baseline, with 1596 of these adolescents completing the follow-up survey. Cued recall of television advertising images for top beer and distilled spirits brands that aired nationally in 2010–2011 (n = 351). Images were digitally edited to remove branding, and the respondents were queried about 20 randomly selected images. An alcohol advertising receptivity score was derived (1 point each for having seen the ad and for liking it, and 2 points for correct brand identification). Fast-food ads that aired nationally in 2010–2011 (n = 535) were similarly queried to evaluate message specificity. MAIN OUTCOMES AND MEASURES Among the underage youth at baseline, we determined (1) the onset of drinking among those who never drank, (2) the onset of binge drinking among those who were never binge drinkers, and (3) the onset of hazardous drinking among those with an Alcohol Use Disorders Identification Test consumption subscore of less than 4. Multivariate regressions were used to predict each outcome, controlling for covariates (demographics, drinking among friends and parents, and sensation seeking), weighting to the US population, and using multiple imputation to address loss to follow-up. RESULTS Underage participants were only slightly less likely than participants of legal drinking age to have seen alcohol ads (the mean percentage of ads seen were 23.4%, 22.7%, and 25.6%, respectively, for youth 15–17, 18–20, and 21–23 years of age; P < .005). The transition to binge and hazardous drinking occurred for 29% and 18% of

Research has suggested that exposure to psychological trauma is associated with increased abuse of psychoactive substances, particularly alcohol. To assess this, we analyzed alcohol consumption, binge drinking, and alcohol dependence among a random sample of 1681 New York City adults 1 year and 2 years after the September 11 attacks. In multivariate models controlling for demographic factors, other stressor exposures, social psychological resources, and history of anti-social behavior, we found that greater exposure to the World Trade Center disaster (WTCD) was associated with greater alcohol consumption at 1 year and 2 years after this event. In addition, our analyses also indicated that exposure to the WTCD was associated with binge drinking at 1 year after but not 2 years after this event. Alcohol dependence, assessed as present in either year 1 or year 2, also was positively associated with greater WTCD exposures. Posttraumatic stress disorder was not associated with alcohol use, once WTCD exposure and other covariates were controlled. Our study suggests that exposure to psychological trauma may be associated with increases in problem drinking long after exposure and deserves further investigation. PMID:15982827

Electrophysiological data suggest a dual role of Y2 receptors (Y2 Rs) as autoreceptors regulating neuropeptide Y release and heteroceptors regulating gamma-aminobutyric acid release in the central amygdala (CeA). Here, we report that neither systemic (JNJ-31020028) nor intra-CeA (BIIE0246) Y2 R antagonism altered operant alcohol responding by alcohol-dependent or non-dependent rats. Conversely, BIIE0246 in the CeA reduced anxiety-like behavior in alcohol-dependent and alcohol-naïve rats. The finding that Y2 R antagonism reduces anxiety-like behavior but not alcohol drinking suggests that these two effects may occur via different functions of the Y2 R (e.g. autoreceptor versus heteroceptor function).

A dual-process model of the alcohol-behavior link is presented, synthesizing 2 of the major social-cognitive approaches: expectancy and myopia theories. Substantial evidence has accrued to support both of these models, and recent neurocognitive models of the effects of alcohol on thought and behavior have provided evidence to support both as well.…

Background Exposure to stress during adolescence is known to be a risk factor for alcohol-use and anxiety disorders. This study examined the effects of footshock stress during adolescence on subsequent alcohol drinking in male and female mice selectively bred for high-alcohol preference (HAP1 lines). Acoustic startle responses and prepulse inhibition (PPI) were also assessed in the absence of, and immediately following, subsequent footshock stress exposures to determine whether a prior history of footshock stress during adolescence would produce enduring effects on anxiety-related behavior and sensorimotor gating. Methods Alcohol-nav̈ve, adolescent (male, n = 27; female, n = 23) and adult (male, n = 30; female, n = 30) HAP1 mice were randomly assigned to a stress or no stress group. The study consisted of 5 phases: (1) 10 consecutive days of exposure to a 30-minute footshock session, (2) 1 startle test, (3) one 30-minute footshock session immediately followed by 1 startle test, (4) 30 days of free-choice alcohol consumption, and (5) one 30-minute footshock session immediately followed by 1 startle test. Results Footshock stress exposure during adolescence, but not adulthood, robustly increased alcohol drinking behavior in both male and female HAP1 mice. Before alcohol drinking, females in both the adolescent and adult stress groups showed greater startle in phases 2 and 3; whereas males in the adolescent stress group showed greater startle only in phase 3. After alcohol drinking, in phase 5, enhanced startle was no longer apparent in any stress group. Males in the adult stress group showed reduced startle in phases 2 and 5. PPI was generally unchanged, except that males in the adolescent stress group showed increased PPI in phase 3 and females in the adolescent stress group showed decreased PPI in phase 5. Conclusions Adolescent HAP1 mice appear to be more vulnerable to the effects of footshock stress than adult mice, as manifested by increased alcohol drinking

Relapse-like ethanol-drinking behavior depends on increased glutamate transmission in the mesocorticolimbic motive circuit. Extracellular glutamate is regulated by a number of glutamate transporters. Of these transporters, glutamate transporter 1 (GLT1) is responsible for the majority of extracellular glutamate uptake. We have recently reported that ceftriaxone (CEF) treatment (i.p.), a β-lactam antibiotic known to elevate GTL1 expression, reduced ethanol intake in male alcohol-preferring (P) rats. We investigated here whether CEF treatment attenuates relapse-like ethanol-drinking behavior. P rats were exposed to free choice of 15% and 30% ethanol for 5 weeks and treated with CEF (50 and 100 mg/kg, i.p.) during the last 5 days of the 2-week deprivation period. Rats treated with CEF during the deprivation period showed a reduction in ethanol intake compared with saline-treated rats upon re-exposure to ethanol; this effect persisted for 9 days. Moreover, CEF-mediated attenuation in relapse to ethanol-drinking behavior was associated with upregulation of GLT1 level in prefrontal cortex and nucleus accumbens core. GLT1 upregulation was revealed only at the higher dose of CEF. In addition, CEF has no effect on relapse-like sucrose-drinking behavior. These findings suggest that ceftriaxone might be used as a potential therapeutic treatment for the attenuation of relapse-like ethanol-drinking behavior.

The authors examined the relation between Greek students' perceptions of alcohol consumption in their pledge classes (descriptive norms) and acceptability of drinking (injunctive norms) and the ability of these normative influences to predict drinking behavior, alcohol-related negative consequences, and symptoms of alcohol dependence concurrently and prospectively over 1 year. Participants were 279 men and 303 women recruited from incoming pledge classes of 12 fraternities and 6 sororities, who completed measures of descriptive and injunctive norms, alcohol use, and consequences. Results revealed that descriptive norms significantly predicted concurrent drinking. After controlling for baseline drinking, injunctive norms significantly predicted drinking 1 year later and predicted alcohol-related consequences and dependency symptoms at baseline and follow-up. The potential to incorporate injunctive norms into preventive interventions is discussed.

Rationale Alcohol effects on behavioral and cognitive mechanisms influence impaired driving performance and decisions to drive after drinking (Barry 1973; Moskowitz and Robinson 1987). To date, research has focused on the ascending limb of the blood alcohol curve, and there is little understanding of how acute tolerance to impairment of these mechanisms might influence driving behavior on the descending limb. Objectives To provide an integrated examination of the degree to which alcohol impairment of motor coordination and inhibitory control contributes to driving impairment and decisions to drive on the ascending and descending limbs of the blood alcohol curve. Methods Social-drinking adults (N=20) performed a testing battery that measured simulated driving performance and willingness to drive, as well as mechanisms related to driving: motor coordination (grooved pegboard), inhibitory control (cued go/no-go task), and subjective intoxication. Performance was tested in response to placebo and a moderate dose of alcohol (0.65 g/kg) twice at comparable blood alcohol concentrations: once on the ascending limb and again on the descending limb. Results Impaired motor coordination and subjective intoxication showed acute tolerance, whereas driving performance and inhibitory control showed no recovery from impairment. Greater motor impairment was associated with poorer driving performance under alcohol, and poorer inhibitory control was associated with more willingness to drive. Conclusions Findings suggest that acute tolerance to impairment of motor coordination is insufficient to promote recovery of driving performance and that the persistence of alcohol-induced disinhibition might contribute to risky decisions to drive on the descending limb.

Alcohol use disorder (AUD) with harmful drinking patterns is on the one hand characterized by impulsive behavior and is on the other hand known to involve structural brain alterations with lower gray matter volume (GMV), especially in the prefrontal cortex (PFC). So far it is unclear whether frontal brain volumes are associated to harmful alcohol drinking and impulsivity, while controlling simultaneously for a wide array of important confounding factors, which are related to alcohol consumption. We used voxel-based morphometry in 99 adults ranging within a continuum of normal to harmful drinking behavior and alcohol dependence, measured by the 'Alcohol Use Disorders Identification Test', to examine whether the severity of harmful drinking is correlated with structural markers, in particular in the PFC and whether such markers are linked to self-reported impulsivity. We included alcohol and nicotine lifetime exposure, age, education, and BMI as covariates to control that GMV decreases were not related to those factors. Harmful drinking was associated with lower GMV in the right frontal pole, left inferior frontal gyrus, and bilateral inferior parietal lobe. GMV loss in the PFC regions was correlated with increased impulsivity. Follow-up mediation analyses showed that the relationship between GMV in the frontal pole and harmful drinking was mediated by impulsivity. Our findings show that PFC reductions are associated with harmful drinking and impulsivity. Our data suggest that reduced frontal pole GM, independent of a number of alcohol drinking associated covariates, e.g. lifetime alcohol consumption, is related to impaired top-down control of alcohol drinking behavior.

Emotional and behavioral regulation has been linked to coping and enhancement motives and associated with different patterns of alcohol use and problems. The current studies examined emotional instability, urgency, and internal drinking motives as predictors of alcohol dependence symptoms and DSM-5 Alcohol Use Disorder. In Study 1, college drinkers (n = 621) completed alcohol involvement and behavioral/emotional functioning assessments. There was an indirect association between emotional instability and dependence symptoms via both coping and enhancement drinking motives which was potentiated by trait urgency. In Study 2, college drinkers (n = 510) completed alcohol involvement, behavioral/emotional functioning, and AUD criteria assessments. A significant indirect effect from emotional instability to the likelihood of meeting AUD criteria, via drinking to cope was found, again potentiated by urgency. PMID:27075609

The purpose of this study is to examine how parental drinking behavior, drinking locations, alcohol outlet density, and types of social support (tangible, emotional, and social companionship) may place children at greater risk for physical abuse. Data on use of physical abuse, drinking behaviors, types of social support, social networks, and demographic information were collected via telephone interviews with 3,023 parent respondents in 50 cities in California. Data on alcohol outlet density were obtained by the California Department of Alcoholic Beverage Control. Multilevel Poisson models were used to analyze data for the drinking levels in the entire sample and dose-response drinking models for drinkers. Social companionship support was related to more frequent use of physical abuse. Having a higher percentage of social companionship support network living within the neighborhood was related to more frequent physical abuse in the full sample. This relationship was moderated by on-premise alcohol outlet density. With regards to drinking behaviors, drinking behaviors from ex-drinkers to frequent heavy drinkers used physically abusive parenting practices more often than lifetime abstainers. The dose-response models show that each additional drinking event at a bar or home/party was related to more frequent use of physical abuse. Practitioners working with parents who abuse their children should be aware that not all social support is beneficial. Findings build evidence that child maltreatment is influenced by the interaction between individual and ecological factors.

Purpose Alcohol-related cognitions, particularly expectancies for drinking and non-drinking and motives for non-drinking, are involved in the initiation, maintenance, and cessation of alcohol use and are hypothesized to play key roles in adolescent decision making. This study explored (a) the relationships between alcohol use expectancies, non-drinking expectancies and non-drinking motives, (b) the roles of these cognitions across hypothesized developmental stages of adolescent alcohol use and (c) the relationships between these cognitions and recent or intended future changes in drinking behavior in a cross-sectional sample. Methods Surveys assessing alcohol use behaviors and attitudes were administered to 1648 high school students. Results Heavier drinkers reported more positive alcohol use expectancies and fewer non-drinking motives than lighter drinkers or non-drinkers, however non-drinking expectancies only differed between non- and rare- drinkers and all subsequent drinking classes. Alcohol use expectancies, non-drinking expectancies and non-drinking motives differentiated students who recently initiated alcohol from those who had not, while non-drinking expectancies and non-drinking motives differentiated binge drinking students who had made recent efforts to reduce/stop their drinking from those who had not. Intentions to initiate or reduce drinking in the coming month were also associated with these alcohol-related cognitions. Conclusion Drinking and non-drinking expectancies, and motives for not drinking may play critical roles in decisions to alter alcohol-use behavior during adolescence. Future exploration of temporal relationships between changes in alcohol-related cognitions and behavioral decision making will be useful in the refinement of effective prevention and intervention strategies.

The aim of the study was to determine the role of alcoholic drinks as a potential source of dietary fluoride by means of measuring fluoride levels in selected alcoholic drinks available on the Polish market that are also diverse in terms of the percentage content of ethanol. The study was conducted on 48 types of drinks with low, medium, and high alcohol content available on the Polish market and offered by various manufacturers, both Polish and foreign. Fluoride concentrations in individual samples were measured by potentiometric method with a fluoride ion-selective electrode. The highest fluoride levels were determined in the lowest percentage drinks (less than 10 % v/v ethanol), with the lowest fluoride levels observed in the highest percentage drinks (above 40 % v/v ethanol). In terms of types of alcoholic drinks, the highest fluoride levels were determined in beers and wines, while the lowest levels were observed in vodkas. These data confirm the fact that alcoholic beverages need to be considered as a significant source of fluoride delivered into the body.

Background: Alcohol consumption during pregnancy and lactation induces detrimental consequences, that are not limited to the direct in utero effects of the drug on fetuses, but extend to maternal care. However, the occurrence and severity of alcohol toxicity are related to the drinking pattern and the time of exposure. The present study investigated in female rats long-term alcohol drinking trajectories, by a continuous and intermittent free-choice paradigm, during pre-gestational time, pregnancy, and lactation; moreover, the consequences of long-term alcohol consumption on the response to natural reward and maternal behavior were evaluated. Methods: Virgin female rats were exposed to home-cage two-bottle continuous- or intermittent “alcohol (20% v/v) vs. water” choice regimen along 12 weeks and throughout pregnancy and lactation. Animals were tested for saccharin preference, and maternal behavior was assessed by recording dams' undisturbed spontaneous home-cage behavior in the presence of their offspring. Results: Our results show that the intermittent alcohol drinking-pattern induced an escalation in alcohol intake during pre-gestational time and lactation more than the continuous access, while a reduction in alcohol consumption was observed during pregnancy, contrarily to the drinking trajectories of the continuous access-exposed rats. Long-term voluntary alcohol intake induced a decreased saccharin preference in virgin female rats and a significant reduction in maternal care, with respect to control dams, although the intermittent drinking produced a greater impairment than the continuous-access paradigm. Conclusion: The present data indicate that both alcohol-drinking patterns are associated to modifications in the drinking trajectories of female rats, in pre-gestational time, during pregnancy and lactation. Moreover, long-lasting alcohol intake can affect sensitivity to natural rewarding stimuli and maternal behavior and sensitivity to natural rewarding

‘Omics' techniques are widely used to identify novel mechanisms underlying brain function and pathology. Here we applied a novel metabolomics approach to further ascertain the role of frontostriatal brain regions for the expression of addiction-like behaviors in rat models of alcoholism. Rats were made alcohol dependent via chronic intermittent alcohol vapor exposure. Following a 3-week abstinence period, rats had continuous access to alcohol in a two-bottle, free-choice paradigm for 7 weeks. Nontargeted flow injection time-of-flight mass spectrometry was used to assess global metabolic profiles of two cortical (prelimbic and infralimbic) and two striatal (accumbens core and shell) brain regions. Alcohol consumption produces pronounced global effects on neurometabolomic profiles leading to a clear separation of metabolic phenotypes between treatment groups, particularly. Further comparisons of regional tissue levels of various metabolites, most notably dopamine and Met-enkephalin, allow the extrapolation of alcohol consumption history. Finally, a high-drinking metabolic fingerprint was identified indicating a distinct alteration of central energy metabolism in the accumbens shell of excessively drinking rats that could indicate a so far unrecognized pathophysiological mechanism in alcohol addiction. In conclusion, global metabolic profiling from distinct brain regions by mass spectrometry identifies profiles reflective of an animal's drinking history and provides a versatile tool to further investigate pathophysiological mechanisms in alcohol dependence.

Research suggests that high school students who participate in sports may be at elevated risk for alcohol use compared to their non-athlete peers; however, reasons for this association are unclear. Alcohol expectancy theory posits that individuals who expect favorable outcomes to occur because of alcohol use are more likely to drink than those who do not endorse such beliefs. As such, the present study was designed to examine the associations of alcohol expectancy outcomes and valuations (i.e., beliefs about whether an outcome is good or bad), as well as alcohol expectancies related to sports functioning (e.g., alcohol's effects on one's ability to learn new plays and recover physically from sporting activities), with risky drinking among high school athletes. Participants were 219 in-season high school athletes (mean age = 15.6, range = 13-18) who completed anonymous self-report surveys. A structural equation model indicated that endorsement of positive alcohol expectancy outcomes and favorable evaluations of negative expectancy outcomes were associated with higher levels of risky drinking. Conversely, greater endorsement of negative athletic-functioning drinking expectancies was associated with lower levels of risky drinking. Future research considerations and implications for intervention efforts targeting high school athletes are discussed.

Alcohol drinking habits and alcoholism are partly genetically determined. Alcohol is degraded primarily by alcohol dehydrogenase (ADH) wherein genetic variation that affects the rate of alcohol degradation is found in ADH1B and ADH1C. It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence interval (CI): 9.1-11) among men with the ADH1B.1/1 genotype compared to 7.5 drinks (95% CI: 6.4-8.7) among men with the ADH1B.1/2 genotype, and the odds ratio (OR) for heavy drinking was 3.1 (95% CI: 1.7-5.7) among men with the ADH1B.1/1 genotype compared to men with the ADH1B.1/2 genotype. Furthermore, individuals with ADH1C slow vs fast alcohol degradation had a higher risk of heavy and excessive drinking. For example, the OR for heavy drinking was 1.4 (95% CI: 1.1-1.8) among men with the ADH1C.1/2 genotype and 1.4 (95% CI: 1.0-1.9) among men with the ADH1B.2/2 genotype, compared with men with the ADH1C.1/1 genotype. Results for ADH1B and ADH1C genotypes among men and women were similar. Finally, because slow ADH1B alcohol degradation is found in more than 90% of the white population compared to less than 10% of East Asians, the population attributable risk of heavy drinking and alcoholism by ADH1B.1/1 genotype was 67 and 62% among the white population compared with 9 and 24% among the East Asian population.

Central ghrelin is required for the rewarding properties of drug abuse. We investigated whether alcohol affects ghrelinergic, dopaminergic, and serotoninergic neurons and growth hormone secretagogue receptor 1A (GHS-R1A) levels in the reward system of the brain. Alcohol-naïve C57BL/6J mice received 2g/kg ethanol (EtOH) intraperitoneally (i.p.). Plasma ghrelin levels decreased between 1 and 4h. We investigated the effects of EtOH administration on plasma ghrelin levels in two different animal models at 1, 3, and 10months of age. Plasma ghrelin levels decreased following the EtOH treatment in 1- and 3-month-old short-term (1-day) alcohol vapor-exposed (STA) mice. In contrast, EtOH administration increased plasma ghrelin levels in 1- and 3-month-old long-term (20-day) alcohol vapor-exposed (LTA) mice. In vivo ghrelin release in the lateral hypothalamus (LH) increased in STA and LTA mice after the i.p. administration of EtOH. EtOH increased in vivo dopamine (DA), but not serotonin (5-HT) release in the LH of STA mice, and increased in vivo DA and 5-HT release in the LH of LTA mice. GHS-R1A mRNA expression and GHS-R1A protein levels in the LH were increased in LTA mice. The number of GHS-R1A-immunoreactive cells was greater in the LH and amygdala of LTA mice. These results support the neurobiological correlation between the development of drinking behavior and activation of ghrelinergic and serotonergic neurons in the LH. The activation of ghrelinergic systems in the amygdala may also induce an increase in 5-HT release in the LH during long-term alcohol intake.

Objective Research shows social and institutional pressure influences drinking, yet determinants of who receives pressure are understudied. This paper examines age, time period, and birth cohort (APC) effects on pressure to stop or reduce drinking among U.S. men and women. Methods Data were drawn from six National Alcohol Surveys (NAS) conducted from 1984 to 2010 (N=32,534). Receipt of pressure during the past year to quit or change drinking from formal (police, doctor, work) and informal (spouse, family, friends) sources was assessed. Results Determinants of pressure were similar for men and women but varied in strength. They included younger age, less education, and younger cohort groups. Cohort effects were stronger for women than men. Conclusions Cohort effects among women may be due to increased alcohol marketing to younger women and the changing social contexts of their drinking. Future studies should assess associations between drinking contexts, pressures, and outcomes. PMID:25395917

Background Despite evidence for genetic influences on alcohol use and alcohol-related cognitions, genetic factors and endophenotypes are rarely incorporated in cognitive models of drinking behavior. This study evaluated a model of ALDH2 and drinking behavior stipulating cognitive factors and alcohol sensitivity as accounting for genetic influences on drinking outcomes. Methods Participants were Asian-American young adults (n = 171) who completed measures of alcohol cognitions (drinking motives, drinking refusal self-efficacy and alcohol expectancies), alcohol sensitivity, drinking behavior and alcohol-related problems as part a prospective study. Structural equation modeling (SEM) evaluated a model of drinking behavior that stipulated indirect effects of ALDH2 on drinking outcomes through cognitive variables and alcohol sensitivity. Results The full model provided an adequate fit to the observed data, with the measurement model explaining 63% of the variance in baseline heavy drinking and 50% of the variance in alcohol-related problems at follow-up. Associations of ALDH2 with cognitive factors and alcohol sensitivity were significant, whereas the association of ALDH2 with drinking was not significant with these factors included in the model. Mediation tests indicated significant indirect effects of ALDH2 through drinking motives, drinking refusal self-efficacy and alcohol sensitivity. Conclusions Results are consistent with the perspective that genetic influences on drinking behavior can be partly explained by learning mechanisms and implicate cognitive factors as important for characterizing associations of ALDH2 and drinking.

Alcohol-related cognitions, particularly expectancies for drinking and nondrinking and motives for nondrinking, are involved in the initiation, maintenance, and cessation of alcohol use and are hypothesized to play key roles in adolescent decision making. This study explored (a) the relationships between alcohol use expectancies, nondrinking expectancies, and nondrinking motives; (b) the roles of these cognitions across hypothesized developmental stages of adolescent alcohol use; and (c) the relationships between these cognitions and recent or intended future changes in drinking behavior in a cross-sectional sample. Surveys assessing alcohol use behaviors and attitudes were administered to 1,648 high school students. Heavier drinkers reported more positive alcohol use expectancies and fewer nondrinking motives than did lighter drinkers or nondrinkers; however, nondrinking expectancies only differed between nondrinkers and rare drinkers and all subsequent drinking classes. Alcohol use expectancies, nondrinking expectancies, and nondrinking motives differentiated students who recently initiated alcohol from those who had not, while nondrinking expectancies and nondrinking motives differentiated binge-drinking students who had made recent efforts to reduce/stop their drinking from those who had not. Intentions to initiate or reduce drinking in the coming month were also associated with these alcohol-related cognitions. Drinking and nondrinking expectancies and motives for not drinking may play critical roles in decisions to alter alcohol-use behavior during adolescence. Future exploration of temporal relationships between changes in alcohol-related cognitions and behavioral decision making will be useful in the refinement of effective prevention and intervention strategies.

The relationship between level of childhood abuse (physical and emotional) and sexual risk behavior of sexually transmitted disease clinic patients in St. Petersburg, Russia was examined through path analyses. Mediating variables investigated were: Alcohol Use Disorder Identification Test (AUDIT), drinking motives (for social interaction, to enhance mood, to facilitate sexual encounters), intimate partner violence (IPV), anxiety, and depression symptoms. Results showed a significant indirect effect of childhood abuse on women's sexual risk behavior: higher level of childhood abuse was associated with a greater likelihood of IPV, motivations to drink, leading to higher AUDIT scores and correlated to higher likelihood of having multiple, new or casual sexual partner(s). No significant effect was identified in paths to condom use. Among men, childhood abuse had no significant effect on sexual risk behavior. Reduction in alcohol-related sexual risk behavior may be achieved by addressing the effects of childhood abuse among female participants.

Energy drinks are popular beverages that typically include high levels of caffeine and other ingredients such as taurine, or caffeine-containing herbs, such as guarana. While energy drinks are often consumed alone, they are also frequently used as mixers for alcoholic beverages. This review summarizes what is known about the scope of use of alcohol mixed with energy drinks, the risks associated with such mixtures, and the objective laboratory data examining how the effects of their consumption differ from consuming alcohol alone. The weight of the evidence reveals that consuming alcohol mixed with energy drinks is riskier than consuming alcohol alone and constitutes a public health concern. Consumption of these mixed beverages is frequent, especially in young and underage drinkers, and compared with alcohol alone, their use is associated with elevated rates of binge drinking, impaired driving, risky sexual behavior, and risk of alcohol dependence. Laboratory research (human and animal) has demonstrated that consuming alcohol mixed with energy drinks leads to altered subjective states including decreased perceived intoxication, enhanced stimulation, and increased desire to drink/increased drinking compared to consuming alcohol alone. Possible underlying mechanisms explaining these observations are highlighted in this review.

The purpose of the present study was to investigate the potential associations of binge drinking detected at the exit of nightclubs and risk behaviors and alcohol effects just after leaving the venue in a representative sample of Brazilian nightclub patrons according to sex. For this purpose, a portal survey study called Balada com Ciência was conducted in 2013 in the megacity of São Paulo, Brazil, using a two-stage cluster sampling survey design. Individual-level data were collected in 2422 subjects at the entrance and 1822 subjects at the exit of 31 nightclubs, and breath alcohol concentration (BrAC) was measured using a breathalyzer. The following day, 1222 patrons answered an online follow-up survey that included questions about risk behaviors and alcohol effects practiced just after leaving the nightclub. Weighted logistic regressions were used to analyze binge drinking associated with risk behaviors by sex. For both sexes, the most prevalent risk behaviors practiced after leaving a nightclub were drinking and driving (men=27.9%; women=20.4%), the use of illicit drugs (men=15.8%; women=9.4%) and risky sexual behavior (men=11.4%; women=6.8%). The practice of binge drinking increased the behavior of illicit drug use after leaving the nightclub by 2.54 times [95% CI: 1.26-5.09] among men who drank and increased the risk of an episode of new alcohol use by 5.80 times [95% CI: 1.50-22.44] among women who drank. Alcoholic blackouts were more prevalent among men [OR=8.92; 95% CI: 3.83-20.80] and women [OR= 5.31; 95% CI: 1.68-16.84] whose BrAC was equivalent to binge drinking compared with patrons with a lower BrAC. Public policies aiming to reduce patrons' BrAC at the exit of nightclubs, such as staff training in responsible beverage service and legislation to prevent alcohol sales to drunk individuals, would be useful to protect patrons from the risk behaviors associated with binge drinking in nightclubs.

Aims To test whether drinking onset moderates genetic and environmental contributions to individual differences in the etiology of alcohol expectancies across adolescence. Design Longitudinal twin design. Setting Community sample from Los Angeles, CA, USA. Participants A total of 1292 male and female twins, aged 11–18 years, were assessed at 1 (n = 440), 2 (n = 587) or 3 (n = 265) occasions as part of the risk factors for the Antisocial Behavior Twin Study. Measurements Social behavioral (SB) alcohol expectancies were measured using an abbreviated version of the Social Behavioral subscale from the Alcohol Expectancy Questionnaire for adolescents (AEQ-A). Drinking onset was defined as >1 full drink of alcohol. Findings Alcohol expectancies increased over age and the increase became more rapid following onset of drinking. The importance of genetic and environmental influences on SB scores varied with age and drinking status, such that variation prior to drinking onset was attributed solely to environmental influences, whereas all post-onset variation was attributed to genetic influences. Results did not differ significantly by sex. Conclusion Only environmental factors explain beliefs about the social and behavioral consequences of alcohol use prior to drinking onset, whereas genetic factors explain an increasing proportion of the variance in these beliefs after drinking onset.

Alcohol dependence continues to be an important health concern and animal models are critical to furthering our understanding of this complex disease. A hallmark feature of alcoholism is a significant increase in alcohol drinking over time. While several different animal models of excessive alcohol (ethanol) drinking exist for mice and rats, a growing number of laboratories are using a model that combines chronic ethanol exposure procedures with voluntary ethanol drinking with mice as experimental subjects. Primarily, these studies use a chronic intermittent ethanol (CIE) exposure pattern to render mice dependent and a 2-h limited access procedure to evaluate drinking behavior. Compared to non-dependent mice that also drink ethanol, the ethanol-dependent mice demonstrate significant increases in voluntary ethanol drinking. The increased drinking significantly elevates blood and brain ethanol concentrations compared to the non-dependent control mice. Studies report that the increased drinking by dependent mice is driven by neuroadaptations in glutamatergic and corticotropin-releasing factor signaling in different brain regions known to be involved in alcohol-related behaviors. The dysregulation of these systems parallels findings in human alcoholics and treatments that demonstrate efficacy in alcoholics can also reduce drinking in this model. Moreover, preclinical findings have informed the development of human clinical trials, further highlighting the translational potential of the model. As a result of these features, the CIE exposure and free-choice drinking model is becoming more widely used and promises to provide more insight into mechanisms of excessive drinking that may be important for developing treatments for human alcoholics. The salient features and possible future considerations for CIE exposure and free-choice drinking in mice are discussed.
Purpose This study examined the association between early initiation of problem behaviors (alcohol drinking, cigarette smoking, and sexual intercourse) and suicidal behaviors (suicidal ideation and suicide attempts), and explored the effect of concurrent participation in these problem behaviors on suicidal behaviors among Korean adolescent males and females. Materials and Methods Data were obtained from the 2006 Korean Youth Risk Behavior Survey, a nationally representative sample of middle and high school students (32,417 males and 31,467 females) in grades seven through twelve. Bivariate and multivariate logistic analyses were conducted. Several important covariates, such as age, family living structure, household economic status, academic performance, current alcohol drinking, current cigarette smoking, current butane gas or glue sniffing, perceived body weight, unhealthy weight control behaviors, subjective sleep evaluation, and depressed mood were included in the analyses. Results Both male and female preteen initiators of each problem behavior were at greater risk for suicidal behaviors than non-initiators, even after controlling for covariates. More numerous concurrent problematic behaviors were correlated with greater likelihood of seriously considering or attempting suicide among both males and females. This pattern was more clearly observed in preteen than in teen initiators although the former and latter were engaged in the same frequency of problem behavior. Conclusion Early initiation of alcohol drinking, cigarette smoking, and sexual intercourse, particularly among preteens, represented an important predictor of later suicidal ideation and suicide attempts in both genders. Thus, early preventive intervention programs should be developed and may reduce the potential risks for subsequent suicidal behaviors. PMID:20046509

Marchigian Sardinian alcohol-preferring (msP) rats exhibit innate preference for alcohol, are highly sensitive to stress and stress-induced alcohol seeking. Genetic analysis showed that over-expression of the corticotropin-releasing factor (CRF) system of msP rats is correlated with the presence of two single nucleotide polymorphisms (SNPs) occurring in the promoter region (position −1836 and −2097) of the CRF1 receptor (CRF1-R) gene. Here we examined whether these point mutations were associated to the innate alcohol preference, stress-induced drinking, and seeking. We have recently re-derived the msP rats to obtain two distinct lines carrying the wild type (GG) and the point mutations (AA), respectively. The phenotypic characteristics of these two lines were compared with those of unselected Wistar rats. Both AA and GG rats showed similar patterns of voluntary alcohol intake and preference. Similarly, the pharmacological stressor yohimbine (0.0, 0.625, 1.25, and 2.5 mg/kg) elicited increased operant alcohol self-administration under fixed and progressive ratio reinforcement schedules in all three lines. Following extinction, yohimbine (0.0, 0.625, 1.25, and 2.5 mg/kg) significantly reinstated alcohol seeking in the three groups. However, at the highest dose this effect was no longer evident in AA rats. Treatment with the CRF1-R antagonist antalarmin (0, 5, 10, and 20 mg/kg) significantly reduced alcohol-reinforced lever pressing in the AA line (10 and 20 mg/kg) while a weaker or no effect was observed in the Wistar and the GG group, respectively. Finally, antalarmin significantly reduced yohimbine-induced increase in alcohol drinking in all three groups. In conclusion, these specific SNPs in the CRF1-R gene do not seem to play a primary role in the expression of the msP excessive drinking phenotype or stress-induced drinking but may be associated with a decreased threshold for stress-induced alcohol seeking and an increased sensitivity to the effects

Despite minimum drinking age laws, underage college students engage in high levels of risky drinking and reach peak lifetime levels of alcohol dependence. A group of presidents of universities and colleges has argued that these laws promote disrespect for laws in general, and do not prevent drinking or related negative consequences. However, no study has investigated the policy-relevant question of whether students who endorse a personal responsibility to obey drinking laws, regardless of their opinions about the laws, are less likely to drink or to experience negative consequences. Therefore, we compared endorsers to non-endorsers, controlling for race, gender, and baseline outcomes, at two universities (Ns = 2007 and 2027). Neither sample yielded a majority (49% and 38% endorsement), but for both universities, all 17 outcome measures were significantly associated with endorsement across all types of analyses. Endorsers were less likely to drink, drank less, engaged in less high-risk behavior (e.g., heavy/binge drinking), and experienced fewer harms (e.g., physical injury), even when controlling for covariates. Racial/ethnic minority groups were more likely to endorse, compared to White students. By isolating a small window of time between high school and college that produces large changes in drinking behavior, and controlling for covariates, we can begin to hone in on factors that might explain relations among laws, risky behaviors, and harms. Internalization of a social norm to adhere to drinking laws could offer benefits to students and society, but subsequent research is needed to pin down causation and causal mechanisms.

Ingesting alcohol and energy drinks together is associated with a decreased awareness of the physical and mental impairment caused by the alcohol without reducing the actual impairment. This is of particular concern for youth who have a baseline of less mature judgment. Adding energy drinks to alcohol tends to increase the rate of absorption through its carbonation and dilution of the alcohol, and keep a person awake longer allowing ingestion of a greater volume of alcohol. At low blood alcohol levels, caffeine appears to decrease some of the impairment from the alcohol, but at higher blood alcohol levels, caffeine does not appear to have a modifying effect on either the physical or mental impairment induced by the alcohol. Obtaining this combination is made easier and more affordable for under aged persons by manufacturers of premixed alcoholic energy drink combination beverages. Awareness by medical and educational personnel and parents of this activity and its potential for harm is unknown.

Attitudes toward alternative behaviors, such as drinking soda instead of alcohol, might contribute to the prediction of young people's drinking behavior. The current study explored the associations between late adolescents' and young adults' attitudes toward alcoholic and non-alcoholic drinks and their alcohol consumption, and whether these associations were moderated by participants' sex, age and education level. Cross-sectional data were collected among 1012 15 to 25-year-olds. Participants completed an online questionnaire on attitudes toward alcoholic and non-alcoholic drinks, binge drinking and monthly alcohol consumption. Data were analyzed by employing structural equation modeling in Mplus. After controlling for the shared variance in both attitudes, attitudes toward alcoholic drinks were positively related and attitudes toward non-alcoholic drinks were negatively related to participants' monthly alcohol use and binge drinking. Relations between attitudes towards alcoholic drinks and monthly alcohol consumption were stronger for boys than for girls and stronger for participants with intermediate education background. Relations between both attitudes and binge drinking were strongest for high educated participants. According to our data, non-alcohol attitudes provide a unique contribution to the prediction of alcohol use.

Objective The purpose of this study was to extend the limited research on college student support for alcohol control policies by using a latent class analysis to examine the shared characteristics of drinking students who support or oppose such policies. Methods We used data from a sample of 2393 students drawn from a larger study on high risk drinking at a mid-western university. Data was collected between October 2005 and May 2007. We conducted a latent class analysis to identify sub-groups of drinking students based on relevant variables. Results The results of the latent class analysis yielded a model which could correctly classify 90% of the students taking the survey into one of four “classes” based upon their response to four items on the questionnaire. Conclusions Interventions would benefit from approaches that target both student perceptions and specific policies that are most conducive to student support and engagement. PMID:20153587

Early consumption of full servings of alcohol and early experience of drunkenness have been linked with alcohol-related harmful effects in adolescence, as well as adult health and social problems. On the basis of secondary analysis of county-level prevalence data, the present study explored the current pattern of drinking and drunkenness among 15- and 16-year-old adolescents in 40 European and North American countries. Data from the 2006 Health Behavior in School Children survey and the European School Survey Project on Alcohol and other Drugs were used. The potential role of alcohol control and policy measures in explaining variance in drinking patterns across countries was also examined. Policy measures and data on adult consumption patterns were taken from the WHO Global Information System on Alcohol and Health, Eurostat and the indicator of alcohol control policy strength developed by Brand DA, Saisana M, Rynn LA et al. [(2007) Comparative analysis of alcohol control policies in 30 countries. PLoS Med 4:e151.]. We found that a non-significant trend existed whereby higher prices and stronger alcohol controls were associated with a lower proportion of weekly drinking but a higher proportion of drunkenness. It is important that future research explores the causal relationships between alcohol policy measures and alcohol consumption patterns to determine whether strict policies do in fact have any beneficial effect on drinking patterns, or rather, lead to rebellion and an increased prevalence of binge drinking.

Objective The aim of this study was to assess whether the effect of parenthood on alcohol intake varies according to the context in which the drinking act occurs. Method The data were drawn from the Canadian Addiction Survey, a national telephone survey conducted in 2004. The analytical sample included 1,079 drinking occasions nested in 498 female drinkers and 926 drinking occasions nested in 403 male drinkers between 18 and 55 years of age. A multilevel linear statistical model was used to estimate the variance related to the drinking occasion (Level 1) and to the parental role (Level 2). Results Parenthood was not associated with alcohol intake per occasion. Drinking context variables brought great explanatory power to the study of alcohol intake, but, overall, the effect of parenthood on alcohol intake did not vary according to the context in which drinking occurs. Only one interaction between the parental role and contextual characteristics was found. Conclusions Men's and women's alcohol intake within drinking contexts is more likely to be influenced by the immediate context in which drinking occurs than by their parental role. The explanation for alcohol behaviors within the general Canadian population may lie as much in the situation as in the person. PMID:21388599

Alcoholics generally display cycles of excessive ethanol intake, abstinence and relapse behavior. Using an animal model of relapse-like drinking, the alcohol deprivation effect (ADE), our laboratory has shown that repeated 2-week cycles of ethanol deprivation and re-exposure, following an initial 6-week access period, result in a robust ADE by alcohol-preferring (P) and high alcohol-drinking (HAD-1 and HAD-2) rats. These rat lines have been selectively bred to prefer a 10% ethanol solution over water. The present study examined whether P and HAD rats would display an ADE using much shorter ethanol deprivation and re-exposure intervals. Rats were given either continuous or periodic concurrent access to multiple concentrations (10%, 20%, and 30% [vol/vol]) of ethanol. The periodic protocol involved access to ethanol for 12 days followed by four cycles of 4 days of deprivation and 4 days of re-exposure to ethanol access. High-alcohol-drinking rats displayed a robust 24-h ADE upon first re-exposure (HAD-1: approximately 5 vs. 8g/kg/day; HAD-2: approximately 6 vs. 9g/kg/day, baseline vs. re-exposure), whereas P rats ( approximately 7 vs. 8g/kg/day) displayed a modest, nonsignificant, increase in 24-h intake. In a separate group of rats, ethanol intake and blood alcohol concentrations after the first hour of the fourth re-exposure cycle were HAD-1: 2.0g/kg and 97 mg%, HAD-2: 2.3g/kg and 73 mg%, and P: 1.2g/kg and 71 mg%; with all three lines displaying a robust first hour ADE. These findings suggest that (a) an ADE may be observed with short ethanol deprivation and re-exposure intervals in HAD rats, and (b) the genetic make-up of the P and HAD rats influences the expression of this ADE.

Energy drinks are popular beverages that typically include high levels of caffeine and other ingredients such as taurine, or caffeine-containing herbs, such as guarana. While energy drinks are often consumed alone, they are also frequently used as mixers for alcoholic beverages. This review summarizes what is known about the scope of use of alcohol mixed with energy drinks (AmED), the risks associated with AmED, and the objective laboratory data examining how AmED differs from alcohol alone. The weight of the evidence reveals that AmED beverages are riskier than alcohol alone and constitute a public health concern. AmED beverage consumption is frequent, especially in young and underage drinkers. AmED use is associated with elevated rates of binge drinking, impaired driving, risky sexual behavior, and risk of alcohol dependence when compared with alcohol alone. Laboratory research (human and animal) has demonstrated that AmED beverages lead to altered subjective states including decreased perceived intoxication, enhanced stimulation, and increased desire to drink/increased drinking compared to alcohol alone. Possible underlying mechanisms explaining these observations are highlighted. PMID:25293549

Objective To examine impaired control over drinking behavior as a mediator of unique pathways from impulsive traits to alcohol outcomes in young adults and to investigate the moderating influence of self-reported sensitivity to alcohol on these pathways. Method Young adult heavy drinkers (N=172; n=82 women) recruited from the community completed self-report measures of impulsive traits (positive urgency, negative urgency, sensation seeking), alcohol sensitivity (Self-Rating of the Effects of Alcohol scale), impaired control over drinking, and alcohol use and problems. Multiple-groups path analysis was used to analyze the data. Results Path coefficients between urgency and impaired control were larger for individuals with lower versus higher self-reported sensitivity to alcohol. The same was true for the association between impaired control and alcohol problems. For participants lower on alcohol sensitivity, significant indirect paths were observed from both positive and negative urgency to all alcohol outcomes (quantity, frequency, and problems) mediated via impaired control. For participants higher on alcohol sensitivity, only the paths from negative urgency (but not positive urgency) to the three alcohol outcomes via impaired control were statistically significant. Sensation seeking was not uniquely associated with impaired control. Conclusions The findings indicate that relatively low sensitivity to the pharmacological effects of alcohol may exacerbate the association of urgency – especially positive urgency – with impaired control, supporting the notion that personality and level of response to alcohol may interact to increase risk for impaired control over drinking.

Underage drinking is a significant problem facing US communities. Several environmental alcohol prevention (EAP) strategies (laws, regulations, responsible beverage service training and practices) successfully address underage drinking. Communities, however, face challenges carrying out these EAP strategies effectively. This small-scale, 3-year, randomized controlled trial assessed whether providing prevention coalitions with Getting To Outcomes-Underage Drinking (GTO-UD), a tool kit and implementation support intervention, helped improve implementation of two common EAP strategies, responsible beverage service training (RBS) and compliance checks. Three coalitions in South Carolina and their RBS and compliance check programs received the 16-month GTO-UD intervention, including the GTO-UD manual, training, and onsite technical assistance, while another three in South Carolina maintained routine operations. The measures, collected at baseline and after the intervention, were a structured interview assessing how well coalitions carried out their work and a survey of merchant attitudes and practices in the six counties served by the participating coalitions. Over time, the quality of some RBS and compliance check activities improved more in GTO-UD coalitions than in the control sites. No changes in merchant practices or attitudes significantly differed between the GTO-UD and control groups, although merchants in the GTO-UD counties did significantly improve on refusing sales to minors while control merchants did not.

Binge alcohol drinking continues to be a public health concern among today's youth and young adults. Moreover, an early onset of alcohol use, which usually takes the form of binge drinking, is associated with a greater risk for developing alcohol use disorders. Given this, it is important to examine this behavior in rat models of alcohol abuse and dependence. Toward that end, the objective of this article is to review findings on binge-like drinking by selectively bred alcohol-preferring (P) and high-alcohol-drinking (HAD) lines of rats. As reviewed elsewhere in this special issue, the P line meets all, and the HAD line meets most, of the proposed criteria for an animal model of alcoholism. One model of binge drinking is scheduled ethanol access during the dark cycle, which has been used by our laboratory for over 20 years. Our laboratory has also adopted a protocol involving the concurrent presentation of multiple ethanol concentrations. When this protocol is combined with limited access, ethanol intake is maximized yielding blood ethanol levels (BELs) in excess, sometimes greatly in excess, of 80 mg%. By extending these procedures to include multiple scheduled ethanol access sessions during the dark cycle for 5 consecutive days/week, P and HAD rats consume in 3 or 4 h as much as, if not more than, the amount usually consumed in a 24 h period. Under certain conditions, using the multiple scheduled access procedure, BELs exceeding 200 mg% can be achieved on a daily basis. An overview of findings from studies with other selectively bred, inbred, and outbred rats places these findings in the context of the existing literature. Overall, the findings support the use of P and HAD rats as animal models to study binge-like alcohol drinking and reveal that scheduled access procedures will significantly increase ethanol intake by other rat lines and strains as well.

The goal of this cross-sectional study was to assess the relationship of alcohol craving with biopsychosocial and addiction factors that are clinically pertinent to alcoholism treatment. Alcohol craving was assessed in 315 treatment-seeking, alcohol dependent subjects using the PACS questionnaire. Standard validated questionnaires were used to evaluate a variety of biological, addiction, psychological, psychiatric, and social factors. Individual covariates of craving included age, race, problematic consequences of drinking, heavy drinking, motivation for change, mood disturbance, sleep problems, and social supports. In a multivariate analysis (R2 = .34), alcohol craving was positively associated with mood disturbance, heavy drinking, readiness for change, and negatively associated with age. The results from this study suggest that alcohol craving is a complex phenomenon influenced by multiple factors. PMID:20716308

The objective of this article is to review the literature on the utility of using the selectively bred alcohol-preferring (P) and high-alcohol-drinking (HAD) lines of rats in studies examining high alcohol drinking in adults and adolescents, craving-like behavior, and the co-abuse of alcohol with other drugs. The P line of rats meets all of the originally proposed criteria for a suitable animal model of alcoholism. In addition, the P rat exhibits high alcohol-seeking behavior, demonstrates an alcohol deprivation effect (ADE) under relapse drinking conditions, consumes amounts of ethanol during adolescence equivalent to those consumed in adulthood, and co-abuses ethanol and nicotine. The P line also exhibits excessive binge-like alcohol drinking, attaining blood alcohol concentrations (BACs) of 200 mg% on a daily basis. The HAD replicate lines of rats have not been as extensively studied as the P rats. The HAD1,2 rats satisfy several of the criteria for an animal model of alcoholism, e.g., these rats will voluntarily consume ethanol in a free-choice situation to produce BACs between 50 and 200 mg%. The HAD1,2 rats also exhibit an ADE under repeated relapse conditions, and will demonstrate similar levels of ethanol intake during adolescence as seen in adults. Overall, the P and HAD1,2 rats have characteristics attributed to an early onset alcoholic, and can be used to study various aspects of alcohol use disorders.

Objective Worldwide, alcohol is the most commonly used psychoactive substance. However, heterogeneity among alcohol users has been widely recognized. This paper presents a typology of alcohol users based on an implementation of idiographic methodology to examine longitudinal daily and cyclic (weekly) patterns of alcohol use at the individual level. Method A secondary data analysis was performed on the pre-intervention data from a large randomized control trial. A time series analysis was performed at the individual level, and a dynamic cluster analysis was employed to identify homogenous longitudinal patterns of drinking behavior at the group level. The analysis employed 180 daily observations of alcohol use in a sample of 177 alcohol users. Results The first order autocorrelations ranged from −.76 to .72, and seventh order autocorrelations ranged from −.27 to .79. Eight distinct profiles of alcohol users were identified, each characterized by a unique configuration of first and seventh autoregressive terms and longitudinal trajectories of alcohol use. External validity of the profiles confirmed the theoretical relevance of different patterns of alcohol use. Significant differences among the eight subtypes were found on gender, marital status, frequency of drug use, lifetime alcohol dependence, family history of alcohol use and the Short Index of Problems. Conclusions Our findings demonstrate that individuals can have very different temporal patterns of drinking behavior. The daily and cyclic patterns of alcohol use may be important for designing tailored interventions for problem drinkers. PMID:24333036

Heavy drinking has increased in recent years and has been linked to numerous health-related risks, particularly in women. A number of factors may play a role in exacerbating the risks linked to heavy drinking, such as impulsivity, which itself is related to a number of risky behaviors. The present study investigated the effects of alcohol (0, 0.5, 0.75 g/kg) on impulsivity in female heavy drinkers (n = 23) and female light drinkers (n = 23) using a double-blind, placebo-controlled outpatient design; all women were tested during follicular phase of the menstrual cycle. Each session, participants completed a range of tasks including subjective measures of abuse liability, cognitive performance tasks, three behavioral impulsivity tasks, and a risk-taking task. Alcohol increased impulsivity on the Immediate and Delayed Memory Task (IMT and DMT) and Delay Discounting task. Heavy drinkers scored higher on impulsivity self-reports and were more impulsive on the IMT and the GoStop task than light drinkers. The high dose of alcohol further increased impulsive performance on the IMT and DMT in heavy drinkers. There were no group differences or alcohol effects on the Balloon Analogue Risk Task. Alcohol increased sedative-like effects more in light drinkers and increased stimulant-like effects and alcohol liking more in heavy drinkers. In summary, female heavy drinkers are less sensitive to the negative effects of alcohol, report more positive effects of alcohol, and are more impulsive than female light drinkers. Moreover, impulsive responding was exacerbated by alcohol drinking among female heavy drinkers, indicating that women who drink at this level are at increased risk for developing alcohol use disorders and engaging in other risky behaviors, particularly after drinking.

Suicide is an escalating public health problem, and alcohol use has consistently been implicated in the precipitation of suicidal behavior. Alcohol abuse may lead to suicidality through disinhibition, impulsiveness and impaired judgment, but it may also be used as a means to ease the distress associated with committing an act of suicide. We reviewed evidence of the relationship between alcohol use and suicide through a search of MedLine and PsychInfo electronic databases. Multiple genetically-related intermediate phenotypes might influence the relationship between alcohol and suicide. Psychiatric disorders, including psychosis, mood disorders and anxiety disorders, as well as susceptibility to stress, might increase the risk of suicidal behavior, but may also have reciprocal influences with alcohol drinking patterns. Increased suicide risk may be heralded by social withdrawal, breakdown of social bonds, and social marginalization, which are common outcomes of untreated alcohol abuse and dependence. People with alcohol dependence or depression should be screened for other psychiatric symptoms and for suicidality. Programs for suicide prevention must take into account drinking habits and should reinforce healthy behavioral patterns. PMID:20617037

The impact of social anxiety on negative alcohol-related behaviors among college students has been studied extensively. Drinking motives are considered the most proximal indicator of college student drinking behavior. The current study examined the mediating role of drinking motives in the relationship that social anxiety symptoms have with problematic (alcohol consumption, harmful drinking, and negative consequences) and safe (protective behavioral strategies) drinking behaviors. Participants were 532 undergraduates who completed measures of social anxiety, drinking motives, alcohol use, harmful drinking patterns, negative consequences of alcohol use, and protective behavioral strategy use. Our results show that students with higher levels of social anxiety symptoms who were drinking for enhancement motives reported more harmful drinking and negative consequences, and used fewer protective behavioral strategies. Thus, students who were drinking to increase their positive mood were participating in more problematic drinking patterns compared with students reporting fewer social anxiety symptoms. Further, conformity motives partially mediated the relationship between social anxiety symptoms and negative consequences. Thus, students with more symptoms of social anxiety who were drinking in order to be accepted by their peers were more likely than others to experience negative consequences. Clinical and research implications are discussed.

Although women appear to be more vulnerable to alcohol-induced pathophysiology than men, the neurobiological basis for sex differences is largely unknown, partially because most studies on alcohol drinking are conducted in male subjects only. The present study examined sex differences in alcohol consumption in two rat strains, Long Evans and Wistar, using multiple behavioral paradigms. The effects of the estrous cycle on alcohol consumption were monitored throughout the study. The results indicated that females drank more alcohol than males when given either continuous or intermittent access to alcohol (vs. water) in their home cages (voluntary drinking). Under operant conditions, no sex or strain differences were found in drinking prior to development of alcohol dependence. However, upon dependence induction by chronic, intermittent alcohol vapor exposure, Wistar rats of both sexes substantially escalated their alcohol intake compared with their nondependent drinking levels, whereas Long Evans rats only exhibited a moderate escalation of drinking. Under these conditions, the estrous cycle had no effect on alcohol drinking in any strain and drinking model. Thus, strain, sex, and drinking conditions interact to modulate nondependent and dependent alcohol drinking. The present results emphasize the importance of including sex and strain as biological variables in exploring individual differences in alcohol drinking and dependence.

Objective: Interventions for college student drinking often incorporate interpersonal factors such as descriptive and/or injunctive norms to correct misperceptions about campus drinking (e.g., BASICS [Brief Alcohol Screening and Intervention for College Students] and social-norms campaigns). Some interventions also focus on intra-personal factors of alcohol consumption, which can be considered as one's own perception of drinking, one's attitude toward drinking, and one's intended outcome related to drinking. The current study sought to extend previous work by examining relationships between both inter- and intrapersonal perceptions of drinking and reported drinking behavior. Method: College students (N = 303) completed questionnaires assessing drinking behaviors, perceptions of other students' attitudes toward drinking (i.e., injunctive norms), their perception of the quantity and frequency of student/friend drinking (i.e., descriptive norms), and their attitudes and perceptions toward their own alcohol consumption (i.e., intrapersonal factors). Results: Multiple regressions were used to analyze the unique influence between inter- and intrapersonal drinking perceptions and drinking behavior. Conclusions: Among the interpersonal perceptions of drinking, only closest friend's drinking significantly predicted alcohol consumption, whereas all three intrapersonal factors significantly predicted alcohol consumption. Suggestions for enhancing college student drinking interventions are discussed. PMID:19261229

This study examined relations between personal strivings and alcohol use among college students. Personal strivings are ongoing goals that individuals are characteristically trying to achieve through their behavior. Participants generated lists of personal strivings following standard instructions and then completed an assessment of alcohol use and related problems. Participants returned to complete a follow-up assessment of drinking behavior after 30 days. Personal strivings were coded into content categories by trained raters using a coding manual. Four content categories were examined for this study: achievement, affiliation, health, and self-presentation. A series of t tests revealed that participants endorsing achievement strivings reported less alcohol-related problems and marginally fewer instances of binge drinking during the 30-day follow-up period. In contrast, participants endorsing self-presentation strivings reported more alcohol-related problems during the follow-up period.

Importance The high prevalence of traumatic brain injuries (TBI) among adolescents has brought much focus to this area in recent years. Sports injuries have been identified as a main mechanism. Although energy drinks, including those mixed with alcohol, are often used by young athletes and other adolescents they have not been examined in relation to TBI. Objective We report on the prevalence of adolescent TBI and its associations with energy drinks, alcohol and energy drink mixed in with alcohol consumption. Design, Settings and Participants Data were derived from the Centre for Addiction and Mental Health’s 2013 Ontario Student Drug Use and Health Survey (OSDUHS). This population-based cross-sectional school survey included 10,272 7th to 12th graders (ages 11–20) who completed anonymous self-administered questionnaires in classrooms. Main Outcome Measures Mild to severe TBI were defined as those resulting in a loss of consciousness for at least five minutes, or being hospitalized for at least one night. Mechanism of TBI, prevalence estimates of TBI, and odds of energy drink consumption, alcohol use, and consumption of energy drinks mixed with alcohol are assessed. Results Among all students, 22.4% (95% CI: 20.7, 24.1) reported a history of TBI. Sports injuries remain the main mechanism of a recent (past year) TBI (45.5%, 95% CI: 41.0, 50.1). Multinomial logistic regression showed that relative to adolescents who never sustained a TBI, the odds of sustaining a recent TBI were greater for those consuming alcohol, energy drinks, and energy drinks mixed in with alcohol than abstainers. Odds ratios were higher for these behaviors among students who sustained a recent TBI than those who sustained a former TBI (lifetime but not past 12 months). Relative to recent TBI due to other causes of injury, adolescents who sustained a recent TBI while playing sports had higher odds of recent energy drinks consumption than abstainers. Conclusions and Relevance TBI remains a

Binge drinking and the onset of alcohol-use disorders usually peak during the transition between late adolescence and early adulthood, and early adolescent onset of alcohol consumption has been demonstrated to increase the risk for alcohol dependence in adulthood. In the present study, we describe an animal model of early adolescent alcohol consumption where animals drink unsweetened and unflavored ethanol in high concentrations (20%). Using this model, we investigated the influence of drinking on alcohol-related appetitive behavior and alcohol consumption levels in early adulthood. Further, we also sought to investigate whether differences in alcohol-related drinking behaviors were specific to exposure in adolescence versus exposure in adulthood. Male Wistar rats were given a 2-bottle choice between 20% ethanol and water in one group and between two water bottles in another group during their adolescence (Postnatal Day [PD] 26-59) to model voluntary drinking in adolescent humans. As young adults (PD85), rats were trained in a paradigm that provided free access to 20% alcohol for 25 min after completing up to a fixed-ratio (FR) 16 lever press response. A set of young adult male Wistar rats was exposed to the same paradigm using the same time course, beginning at PD92. The results indicate that adolescent exposure to alcohol increased consumption of alcohol in adulthood. Furthermore, when investigating differences between adolescent high and low drinkers in adulthood, high consumers continued to drink more alcohol, had fewer FR failures, and faster completion of FR schedules in adulthood, whereas the low consumers were no different from controls. Rats exposed to ethanol in young adulthood also increased future intake, but there were no differences in any other components of drinking behavior. Both adolescent- and adult-exposed rats did not exhibit an increase in lever pressing during the appetitive challenge session. These data indicate that adolescent and early

Cessation from chronic alcohol abuse often produces a dysphoric state that can persist into protracted withdrawal. This dysphoric state is theorized to function as a negative reinforcer that maintains excessive alcohol consumption and/or precipitates relapse in those struggling to abstain from alcohol. However, we know relatively little regarding the impact of cessation from binge drinking on behavioral measures of negative affect and related neurobiology. Male C57BL/6J mice were given access to unsweetened 20% alcohol for 6 weeks under modified Drinking-in-the-dark procedures, followed by behavioral testing beginning either 1 or 21 days into withdrawal. Mice were administered a behavioral test battery consisting of: the elevated plus maze, light/dark box, novel object test, marble burying test, Porsolt forced swim test and sucrose preference test to assess anxiogenic and depressive signs. Egr1 immunostaining was used to quantify cellular activity within the central nucleus of the amygdala (CEA), basolateral amygdala (BLA), bed nucleus of the stria terminalis (BNST), and the nucleus accumbens (Acb) shell (AcbSh) and core (AcbC). Compared to water controls, alcohol-drinking mice exhibited higher indices of emotionality in the majority of behavioral assays. The hyper-emotionality exhibited by binge drinking mice was apparent at both withdrawal time-points and correlated with higher Egr1+ cell counts in the CEA and BNST, compared to controls. These data show that affective symptoms emerge very early after cessation of binge drinking and persist into protracted withdrawal. A history of binge drinking is capable of producing enduring neuroadaptations within brain circuits mediating emotional arousal.

The consumption of alcohol mixed with energy drinks (AmED) has been associated with higher rates of binge drinking and impaired driving when compared with alcohol alone. However, it remains unclear why the risks of use of AmED are heightened compared with alcohol alone even when the doses of alcohol consumed are similar. Therefore, the purpose of this laboratory study was to investigate if the rate of self-paced beverage consumption was faster for a dose of AmED versus alcohol alone using a double-blind, within-subjects, placebo-controlled study design. Participants (n = 16) of equal gender who were social drinkers attended 4 separate test sessions that involved consumption of alcohol (1.97 ml/kg vodka) and energy drinks, alone and in combination. On each test day, the dose assigned was divided into 10 cups. Participants were informed that they would have a 2-h period to consume the 10 drinks. After the self-paced drinking period, participants completed a cued go/no-go reaction time (RT) task and subjective ratings of stimulation and sedation. The results indicated that participants consumed the AmED dose significantly faster (by ∼16 min) than the alcohol dose. For the performance task, participants' mean RTs were slower in the alcohol conditions and faster in the energy-drink conditions. In conclusion, alcohol consumers should be made aware that rapid drinking might occur for AmED beverages, thus heightening alcohol-related safety risks. The fast rate of drinking may be related to the generalized speeding of responses after energy-drink consumption. (PsycINFO Database Record

Purpose: To retrospectively evaluate the prognostic value of smoking and drinking status in patients with head-and-neck squamous cell carcinomas. Methods and Materials: All patients with all stages and sites were included if complete information was available on baseline smoking and alcohol behavior (never, former, active), disease stage, primary site, radiation dose, sex, and age. Treatment was radiotherapy in 973 patients, postoperative radiotherapy in 469, and chemoradiotherapy in 429. Statistical analysis was performed with Kaplan-Meier and Cox methods. Results: Data from 1,871 patients were available. At baseline, 9% of patients never smoked, 40% were former smokers, and 51% were active smokers; 20% never drank, 25% were former drinkers, and 55% were active drinkers. Smoking was associated with inferior local control and survival. For local control, the hazard ratio (HR) of active smokers vs. former smokers was 1.5 (p = 0.0001). For survival, the HRs of former smokers and active smokers vs. those who never smoked were also statistically significant (1.3 and 1.7, respectively, p = 0.000001). Alcohol drinking was associated with local control (p = 0.03), and was associated with survival. For survival, HRs of former and active drinkers compared with those who never drank were, respectively, 1.1 (p = 0.01) and 1.28 (p = 0.001). Adjusted 5-year local control and survival rates for those who never smoked and never drank were 87% and 77%, respectively, and for those who were both active smokers and active drinkers were 72% (p = 0.007) and 52% (p = 0.0009), respectively. Conclusion: Smoking and drinking at baseline were associated with poor outcomes in these patients.

Alcohol dependence and alcohol intoxication are important risk factors for suicidal behavior. However, the mechanism for the relationship remains unclear. This review presents a conceptual framework relating alcohol to suicidal behavior. Distal risk factors create a statistical potential for suicide. Alcohol dependence, as well as associated comorbid psychopathology and negative life events, act as distal risk factors for suicidal behavior. Proximal risk factors determine the timing of suicidal behavior by translating the statistical potential of distal risk factors into action. The acute effects of alcohol intoxication act as important proximal risk factors for suicidal behavior among the alcoholic and nonalcoholic alike. Mechanisms responsible for alcohol's ability to increase the proximal risk for suicidal behavior include alcohol's ability to: (1) increase psychological distress, (2) increase aggressiveness, (3) propel suicidal ideation into action through suicide-specific alcohol expectancies, and (4) constrict cognition which impairs the generation and implementation of alternative coping strategies. Moreover, the proximal risk factors associated with acute intoxication are consistent with Baumeister's (1990) escape theory of suicide. Suggestions for additional research are discussed, including the possibility that a nonlinear cusp catastrophe model characterizes the relationship between alcohol intoxication and suicidal behavior.

The current study examined whether the relationship between drinking motives and alcohol-related outcomes was mediated by college adjustment. Participants (N=253) completed an online survey that assessed drinking motives, degree of both positive and negative college adjustment, typical weekly drinking, and past month negative alcohol-related consequences. Structural equation modeling examined negative alcohol consequences as a function of college adjustment, drinking motives, and weekly drinking behavior in college students. Negative college adjustment mediated the relationship between coping drinking motives and drinking consequences. Positive college adjustment was not related to alcohol consumption or consequences. Positive reinforcement drinking motives (i.e. social and enhancement) not only directly predicted consequences, but were partially mediated by weekly drinking and degree of negative college adjustment. Gender specific models revealed that males exhibited more variability in drinking and their positive reinforcement drinking motives were more strongly associated with weekly drinking. Uniquely for females, coping motives were directly and indirectly (via negative adjustment) related to consequences. These findings suggest that interventions which seek to decrease alcohol-related risk may wish to incorporate discussions about strategies for decreasing stress and increasing other factors associated with better college adjustment.

Alcohol abuse is a major problem, especially among students on and around college campuses. We use the mathematical framework of  and study the role of environmental factors on the long term dynamics of an alcohol drinking population. Sensitivity and uncertainty analyses are carried out on the relevant functions (for example, on the drinking reproduction number and the extinction time of moderate and heavy drinking because of interventions) to understand the impact of environmental interventions on the distributions of drinkers. The reproduction number helps determine whether or not the high-risk alcohol drinking behavior will spread and become persistent in the population, whereas extinction time of high-risk drinking measures the effectiveness of control programs. We found that the reproduction number is most sensitive to social interactions, while the time to extinction of high-risk drinkers is significantly sensitive to the intervention programs that reduce initiation, and the college drop-out rate. The results also suggest that in a population, higher rates of intervention programs in low-risk environments (more than intervention rates in high-risk environments) are needed to reduce heavy drinking in the population.

Emergency Department (ED) visits due to energy drinks rose drastically from 2007 to 2011. Consuming alcohol mixed with energy drinks by young people is particularly concerning. Among youth (ages 14–20) in the ED reporting past-year alcohol use, we assessed frequency, reasons, and medical consequences of consuming alcohol and energy drinks in the same beverage or on the same occasion, and relationships with other risk behaviors. The sample included 439 youth (Mage=18.6 years, SD=1.4; 41% male; 73% Caucasian): those who drank alcohol, but not energy drinks (Non-users; 41%, n=178), those who drank alcohol and energy drinks on separate occasions (Separate; 23%, n=103), and those who combined alcohol and energy drinks in the same beverage or on the same occasion (Combined; 36%, n=158). Common reasons for combining energy drinks and alcohol were hiding the flavor of alcohol (39%) and liking the taste (36%). Common consequences were feeling jittery (71%) and trouble sleeping (46%). Combined users had the highest rates of risk behaviors (e.g., drug use, sexual risk behaviors, driving after drinking) and alcohol use severity. Multinomial logistic regression indicated that men, those who had sex after substance use, those who had used drugs, and those with higher alcohol severity were more likely to be Combined users than Non-Users. Those with higher alcohol severity were also more likely to be Combined users than Separate users. Combining energy drinks and alcohol is associated with higher rates of other risk behaviors among young drinkers. Future studies are needed to determine longitudinal relationships of energy drink use on substance use problem trajectories. PMID:25528143

Alcoholic drinks are capable of triggering a wide range of allergic and allergic-like responses, including rhinitis, itching, facial swelling, headache, cough and asthma. Limited epidemiological data suggests that many individuals are affected and that sensitivities occur to a variety of drinks, including wine, beer and spirits. In surveys of asthmatics, over 40% reported the triggering of allergic or allergic-like symptoms following alcoholic drink consumption and 30 - 35% reported worsening of their asthma. Sensitivity to ethanol itself can play a role in triggering adverse responses, particularly in Asians, which is due mainly to a reduced capacity to metabolize acetaldehyde. In Caucasians, specific non-alcohol components are the main cause of sensitivities to alcoholic drinks. Allergic sensitivities to specific components of beer, spirits and distilled liquors have been described. Wine is clearly the most commonly reported trigger for adverse responses. Sensitivities to wine appear to be due mainly to pharmacological intolerances to specific components, such as biogenic amines and the sulphite additives. Histamine in wine has been associated with the triggering of a wide spectrum of adverse symptoms, including sneezing, rhinitis, itching, flushing, headache and asthma. The sulphite additives in wine have been associated with triggering asthmatic responses. Clinical studies have confirmed sensitivities to the sulphites in wine in limited numbers of individuals, but the extent to which the sulphites contribute to wine sensitivity overall is not clear. The aetiology of wine-induced asthmatic responses may be complex and may involve several co-factors.

Although alcohol expectancy (expectations about the effects of drinking alcohol on one's behavior and mood) and drinking refusal self-efficacy (one's perceived ability to resist drinking in high-risk situations) have consistently been demonstrated to be useful to our understanding of alcohol use and abuse, the specificity of these constructs to alcohol consumption has not been previously demonstrated. Using 161 first-year psychology students and multiple regression analyses this study indicated that alcohol expectancies and drinking refusal self-efficacy were specifically related to quantity of alcohol consumption, but not to caffeine or nicotine intake. These results provide empirical evidence to confirm the theoretical and practical utility of these two cognitive constructs to alcohol research and serve to strengthen the theoretical foundations of alcohol expectancy theory.
Alcohol dependence is characterized by conflict between approach and avoidance motivational orientations for alcohol that operate in automatic and controlled processes. This article describes the first study to investigate the predictive validity of these motivational orientations for relapse to drinking after discharge from alcohol detoxification treatment in alcohol-dependent patients. One hundred twenty alcohol-dependent patients who were nearing the end of inpatient detoxification treatment completed measures of self-reported (Approach and Avoidance of Alcohol Questionnaire; AAAQ) and automatic (modified Stimulus-Response Compatibility task) approach and avoidance motivational orientations for alcohol. Their drinking behavior was assessed via telephone follow-ups at 2, 4, and 6 months after discharge from treatment. Results indicated that, after controlling for the severity of alcohol dependence, strong automatic avoidance tendencies for alcohol cues were predictive of higher percentage of heavy drinking days (PHDD) at 4-month (β = 0.22, 95% CI [0.07, 0.43]) and 6-month (β = 0.22, 95% CI [0.01, 0.42]) follow-ups. We failed to replicate previous demonstrations of the predictive validity of approach subscales of the AAAQ for relapse to drinking, and there were no significant predictors of PHDD at 2-month follow-up. In conclusion, strong automatic avoidance tendencies predicted relapse to drinking after inpatient detoxification treatment, but automatic approach tendencies and self-reported approach and avoidance tendencies were not predictive in this study. Our results extend previous findings and help to resolve ambiguities with earlier studies that investigated the roles of automatic and controlled cognitive processes in recovery from alcohol dependence.

The important implications generated by binge drinking among university students justify the interest to determine which factors predict its occurrence. Specifically, this study aims to assess the role of personality and drinking onset in predicting weekly alcohol consumption, and the impact of the whole set of variables in predicting the number of consequences associated with consumption in undergraduates. Two hundred and thirteen freshmen who were intensive consumers (binge drinkers) from the University Complutense of Madrid were evaluated. All of them filled in a self-registration of consumption, the BIS-11, the NEO-FFI and the IECI consequences associated with intake. The hierarchical regression analysis shows that the drinking onset appears to be a relevant predictor variable in explaining weekly consumption and the number of consequences. The same can be said of the weekly consumption variable with regard to the number of consequences. In general, the influence of personality is quite limited. It is interesting to point out that responsibility and impulsivity, along with age, explain most of the weekly consumption behavior among males. With respect to the consequences of consumption, only impulsivity and neuroticism contribute to explain them, but with less strength than age and weekly consumption. Our results justify the need to plan tighter interventions and consider new predictors that help to explain further weekly consumption in women.

Mindfulness and drinking motives have both been linked to affect regulation, yet the relationship between mindfulness and drinking motives is poorly understood. The present study examined whether drinking motives, particularly mood regulatory motives, mediated the associations between facets of mindfulness and alcohol-related outcomes among college students (N = 297). We found three specific facets of mindfulness (describing, nonjudging of inner experience, and acting with awareness) to have negative associations with alcohol outcomes. Importantly, specific drinking motives mediated these associations such that lower levels of mindfulness were associated with drinking for distinct reasons (enhancement, coping, conformity), which in turn predicted alcohol use and/or alcohol problems. Our findings suggest that drinking motives, especially mood regulatory and negative reinforcement motives, are important to examine when studying the role of mindfulness in college student drinking behavior.

The objective of this study was to determine the drinking patterns of high school students in central Thailand. Eleven thousand three hundred sixty high school students from central Thailand were divided into 2 groups (drinkers and nondrinkers) according to their alcohol consumption. Information was obtained by an anonymous self-reporting questionnaire which consisted of 2 parts: general characteristics, and characteristics of alcohol drinking behavior. Data were analyzed using descriptive and inferential statistics by a computerized statistical package. The socio-demographic factors related to the student's alcohol consumption during the previous 12 months were: age > 15 years old, male sex, grades 9 and 11 education level, living in a private dormitory, staying with a relative or a friend, having a grade point average <2.0 or >3.0, having a job earning money and having family members with alcohol/drug problems (p<0.05). Drinking patterns were classified into 5 categories: life time drinking, drinking during the previous year, drinking during the previous 30 days, binge drinking during the previous 30 days and drinking until intoxication during the previous 30 days. A higher proportion of drinking was reported by boys than girls. The prevalence of drinking increased in proportion to the educational level. The 3 main drinking places were parties (48.5%), at home or in the dormitory (37.5%) and in shops around the school (12.4%). Boys drank alcohol on average 1-2 times per month in 59.8% and 1-2 standard drinks per time in 38.6%. Eighty point one percent of girls drank alcohol 1-2 times per month and 1-2 standard drinks per time in 55.6%. Drinking alcohol among high school students should be controlled by limiting access to alcoholic beverages in order to reduce accidents, injuries, violence and alcohol-related health problems among young people.

Chronic intermittent access to alcohol leads to the escalation of alcohol intake, similar to binge drinking in humans. Converging lines of evidence suggest that impairment of medial prefrontal cortex (mPFC) cognitive function and overactivation of the central nucleus of the amygdala (CeA) are key factors that lead to excessive drinking in dependence. However, the role of the mPFC and CeA in the escalation of alcohol intake in rats with a history of binge drinking without dependence is currently unknown. To address this issue, we examined FBJ murine osteosarcoma viral oncogene homolog (Fos) expression in the mPFC, CeA, hippocampus, and nucleus accumbens and evaluated working memory and anxiety-like behavior in rats given continuous (24 h/d for 7 d/wk) or intermittent (3 d/wk) access to alcohol (20% vol/vol) using a two-bottle choice paradigm. The results showed that abstinence from alcohol in rats with a history of escalation of alcohol intake specifically recruited GABA and corticotropin-releasing factor (CRF) neurons in the mPFC and produced working memory impairments associated with excessive alcohol drinking during acute (24–72 h) but not protracted (16 –68 d) abstinence. Moreover, abstinence from alcohol was associated with a functional disconnection of the mPFC and CeA but not mPFC and nucleus accumbens. These results show that recruitment of a subset of GABA and CRF neurons in the mPFC during withdrawal and disconnection of the PFC–CeA pathway may be critical for impaired executive control over motivated behavior, suggesting that dysregulation of mPFC interneurons may be an early index of neuroadaptation in alcohol dependence.

Heavy episodic drinking early in adolescence is associated with increased risk of addiction and other stress-related disorders later in life. This suggests that adolescent alcohol abuse is an early marker of innate vulnerability and/or binge exposure impacts the developing brain to increase vulnerability to these disorders in adulthood. Animal models are ideal for clarifying the relationship between adolescent and adult alcohol abuse, but we show that methods of involuntary alcohol exposure are not effective. We describe an operant model that uses multiple bouts of intermittent access to sweetened alcohol to elicit voluntary binge alcohol drinking early in adolescence (~postnatal days 28-42) in genetically heterogeneous male Wistar rats. We next examined the effects of adolescent binge drinking on alcohol drinking and anxiety-like behavior in dependent and non-dependent adult rats, and counted corticotropin-releasing factor (CRF) cell in the lateral portion of the central amygdala (CeA), a region that contributes to regulation of anxiety- and alcohol-related behaviors. Adolescent binge drinking did not alter alcohol drinking under baseline drinking conditions in adulthood. However, alcohol-dependent and non-dependent adult rats with a history of adolescent alcohol binge drinking did exhibit increased alcohol drinking when access to alcohol was intermittent. Adult rats that binged alcohol during adolescence exhibited increased exploration on the open arms of the elevated plus maze (possibly indicating either decreased anxiety or increased impulsivity), an effect that was reversed by a history of alcohol dependence during adulthood. Finally, CRF cell counts were reduced in the lateral CeA of rats with adolescent alcohol binge history, suggesting semi-permanent changes in the limbic stress peptide system with this treatment. These data suggest that voluntary binge drinking during early adolescence produces long-lasting neural and behavioral effects with implications

College students' use of digital communication technology has led to a rapid expansion of digital alcohol marketing efforts. Two surveys (total usable n = 637) were conducted to explore college students' experiences with alcohol-related social media, their decision making related to alcohol use, and their problematic drinking behaviors. Study results indicated that students' use of alcohol-related social media predicted their problem drinking behaviors. In addition, students' wishful identification, perceived desirability, perceived similarity, and normative beliefs predicted their expectancies for drinking alcohol. Finally, students' expectancies for drinking alcohol predicted their problematic drinking behaviors.

Energy drinks, the fastest growing segment in the beverage market, have become popular mixers with alcohol. The emerging research examining the use of alcohol mixed with energy drinks (AmEDs) indicates that the combination of caffeine-containing energy drinks with alcohol may be riskier than the use of alcohol alone. The public health concerns arising from AmED use are documented in different research domains. Epidemiologic studies reveal that the consumption of AmEDs is frequent among young and underage drinkers, demographic groups that are more likely to experience the harms and hazards associated with alcohol use. In addition, for all consumers, elevated rates of binge drinking and risk of alcohol dependence have been associated with AmED use when compared to alcohol alone. Results from laboratory studies help explain why AmED use is associated with excessive intake of alcohol. When an energy drink (or caffeine) is combined with alcohol, the desire (or urge) to drink more alcohol is more pronounced in both humans and animals than with the same dose of alcohol alone. The experience of drinking alcohol appears to be more rewarding when combined with energy drinks. Given that caffeine in other foods and beverages increases preference for those products, further research on AmEDs may elucidate the underlying mechanisms that contribute to alcohol dependence.

Distinct environmental and conditioned stimuli influencing ethanol-associated appetitive and consummatory behaviors may jointly contribute to alcohol addiction. To develop an effective translational animal model that illuminates this interaction, daily seeking responses, maintained by alcohol-associated conditioned stimuli (CSs), need to be dissociated from alcohol drinking behavior. For this, we established a procedure whereby alcohol seeking maintained by alcohol-associated CSs is followed by a period during which rats have the opportunity to drink alcohol. This cue-controlled alcohol-seeking procedure was used to compare the effects of naltrexone and GSK1521498, a novel selective μ-opioid receptor antagonist, on both voluntary alcohol-intake and alcohol-seeking behaviors. Rederived alcohol-preferring, alcohol-nonpreferring, and high-alcohol-drinking replicate 1 line of rats (Indiana University) first received 18 sessions of 24 h home cage access to 10% alcohol and water under a 2-bottle choice procedure. They were trained subsequently to respond instrumentally for access to 15% alcohol under a second-order schedule of reinforcement, in which a prolonged period of alcohol-seeking behavior was maintained by contingent presentations of an alcohol-associated CS acting as a conditioned reinforcer. This seeking period was terminated by 20 min of free alcohol drinking access that achieved significant blood alcohol concentrations. The influence of pretreatment with either naltrexone (0.1−1−3 mg/kg) or GSK1521498 (0.1–1–3 mg/kg) before instrumental sessions was measured on both seeking and drinking behaviors, as well as on drinking in the 2-bottle choice procedure. Naltrexone and GSK1521498 dose-dependently reduced both cue-controlled alcohol seeking and alcohol intake in the instrumental context as well as alcohol intake in the choice procedure. However, GSK1521498 showed significantly greater effectiveness than naltrexone, supporting its potential use

Objective: Poor mental health, sleep problems, drinking motivations, and high-risk drinking are prevalent among college students. However, research designed to explicate the interrelationships among these health risk behaviors is lacking. This study was designed to assess the direct and indirect influences of poor mental health (a latent factor consisting of depression, anxiety, and stress) to alcohol use and alcohol-related consequences through the mediators of global sleep quality and drinking motives in a comprehensive model. Method: Participants were 1,044 heavy-drinking college students (66.3% female) who completed online surveys. Results: A hybrid structural equation model tested hypotheses involving relations leading from poor mental health to drinking motives and poorer global sleep quality to drinking outcomes. Results showed that poor mental health significantly predicted all four subscales of drinking motivations (social, coping, conformity, and enhancement) as well as poor sleep. Most of the drinking motives and poor sleep were found to explain alcohol use and negative alcohol consequences. Poor sleep predicted alcohol consequences, even after controlling for all other variables in the model. The hypothesized mediational pathways were examined with tests of indirect effects. Conclusions: This is the first study to assess concomitantly the relationships among three vital health-related domains (mental health, sleep behavior, and alcohol risk) in college students. Findings offer important implications for college personnel and interventionists interested in reducing alcohol risk by focusing on alleviating mental health problems and poor sleep quality.

In apparent contrast to the alleged importance of positive alcohol expectancies in alcohol (ab)use, a series of studies using the Implicit Association Test (IAT; [Greenwald, A. G., McGhee, D. E., & Schwartz, J.L.K. (1998). Measuring individual differences in implicit cognition: The Implicit Association Test. Journal of Personality and Social Psychology, 74, 1464-1480]), found that heavy and light drinkers display more negative implicit attitudes toward alcohol than toward sodas (e.g., [Wiers, R. W., van Woerden, N., Smulders, F. T. Y., & de Jong, P. J. (2002). Implicit and explicit alcohol-related cognitions in heavy and light drinkers. Journal of Abnormal Psychology, 111, 648-658]). One explanation for this might be that the negative-alcohol IAT effect reflects an artifact of the IAT procedure and are due to its relative nature and/or its sensitivity to task recoding strategies. Therefore, the present study used a non-relative measure that has been argued to be robust against participants' task recoding strategies (Extrinsic Affective Simon Test; EAST, [De Houwer, J. (2001). A structural and process analysis of the Implicit Association Test. Journal of Experimental Social Psychology, 37, 443-451]) to test heavy (n=16) and light (n=16) drinkers' automatic affective associations with alcohol and sodas. Heavy and light drinkers displayed clear positive associations with sodas and neutral (or ambivalent) automatic associations with alcohol. Importantly, positive automatic alcohol associations predicted unique variance of alcohol (mis)use and was the single best predictor of individuals' alcohol problems, underlining the idea that they do play a role in alcohol (mis)use.

While affiliation with Greek fraternities/sororities and intercollegiate athletic teams is associated with heavier drinking (Meilman et al., 1999), few studies have compared reasons for drinking among these groups. A sample of 1,541 students, identifying as either Greeks or athletes, completed an online survey. Athletes were significantly higher than Greeks on conformity reason for drinking. Tests of independent correlations indicated the magnitude of the past behavior to intention link was considerably stronger for Greeks. Greeks experienced significantly more social problems from drinking. Several group by gender ANOVA models found significant main effects with highest drinking rates, usually among Greek males, and lowest among female athletes. Understanding these specific group differences informs recommendations for group-specific and tailored educational interventions, which are discussed.

Adolescent heavy alcohol drinking increases the risk for alcohol use disorders in adulthood, yet mechanisms conferring increased risk are not well understood. We propose that adolescent alcohol drinking shapes alcohol's aversive or appetitive properties in adulthood. Alcohol normally drives aversive learning and alcohol-predictive cues are avoided. We hypothesize that through adolescent heavy drinking alcohol gains access to appetitive learning. A primary consequence is that alcohol-predictive cues become valued and sought out. To test this hypothesis, we gave genetically heterogeneous, male Long Evans rats voluntary, chronic intermittent access to water or alcohol throughout adolescence and then identified moderate and heavy alcohol drinkers. After a short abstinence period, we assessed the aversive or appetitive properties of alcohol using flavor learning procedures. We compared alcohol to the known appetitive properties of sugar. Flavor learning in adult rats who were alcohol-naïve or adolescent moderate alcohol drinkers revealed alcohol to be aversive and sugar to be appetitive. The same flavor learning procedures revealed both alcohol and sugar to be appetitive in adult rats who were adolescent heavy drinkers. The results demonstrate that alcohol gains access to neurobehavioral circuits for appetitive learning through adolescent heavy alcohol drinking.

Alcohol may be used and misused for different reasons, i.e., to enhance positive affect and to cope with negative affect. These to pathways are thought to depend on two distinct and relatively stable neurobiological systems: the behavioral activation (BAS; i.e., fun seeking, drive, reward responsiveness) and behavioral inhibition (BIS) systems. This study investigates the associations of BAS and BIS sensitivity with risky single-occasion drinking and alcohol use disorder in a representative sample of 5362 young Swiss men. In order to better understand the contribution of more proximal motivational factors in the associations of BIS and BAS with alcohol outcomes, mediations via drinking motives (i.e., enhancement, social, coping, conformity) was also tested. Risky single-occasion drinking and alcohol use disorder were positively associated with fun seeking and negatively with reward responsiveness. Drive was negatively associated with risky single-occasion drinking. BIS was positively associated with alcohol use disorder and negatively with risky single-occasion drinking. Positive associations of fun seeking with risky single-occasion drinking and alcohol use disorder were partially mediated mainly by enhancement motives. Negative association of drive with risky single-occasion drinking was partially mediated by conformity motives. The negative reward responsiveness—alcohol use disorder association was partially mediated, whereas the negative reward responsiveness—risky single-occasion drinking association was fully mediated, mainly by coping and enhancement motives. The positive BIS–alcohol use disorder association was fully mediated mainly by coping motives. Fun seeking constitutes a risk factor, whereas drive and reward responsiveness constitute protective factors against alcohol misuse and disorder. BIS constitutes a protective factor against risky single-occasion drinking and a risk factor for alcohol use disorder. The results of the mediation analysis

The present study examined a range of injunctive norms for alcohol use and related consequences from less severe behaviors (e.g., drinking with friends) to more severe behaviors (e.g., drinking enough alcohol to pass out), and their relationship with alcohol consumption and alcohol-related negative consequences among college students. In addition, this research aimed to determine if these relationships between injunctive norms and consequences were moderated by alcohol consumption and level of identification with the typical same-sex college student. A random sample (N = 1,002) of undergraduates (56.9% female) completed a Web–based survey that was comprised of measures of drinking behavior, perceived approval of drinking behaviors that ranged in severity (i.e., injunctive norms), and level of identification with the typical same-sex college student. Results suggest that the association between negative consequences and injunctive drinking norms depend on one's own drinking behavior, identification with other students, and the severity of the alcohol use and related consequences for which injunctive norms are assessed. Findings are discussed in terms of false consensus and false uniqueness effects, and deviance regulation perspectives. Implications for preventative interventions are discussed. PMID:20565144

Objective: This study examined childhood abuse, problem behavior, drinking style, and dating violence (DV). Our goal was to assess whether (a) alcohol use—related beliefs and behaviors (“drinking style”) would be associated with DV perpetration and victimization, (b) drinking style would mediate the relationship between childhood abuse and DV, and (c) the drinking style—DV relationship would be attributable to propensity for problem behavior. Method: Cross-sectional survey data were collected from 456 youth ages 14—21 years who were patients in an urban emergency department. Participants were eligible if they were unmarried and reported past-month alcohol use and dating in the past year. By design, the sample was 50% female. Data were analyzed using structural equation modeling. Results: For both males and females, past-year DV was associated with a more risky drinking style, characterized by more frequent alcohol use, alcohol-aggression expectancies, drinking to cope, and beliefs that alcohol is disinhibiting and that being drunk provides a “time-out” from behavioral expectations. Drinking style mediated the childhood victimization—DV relationship for males and females. However, when propensity for problem behavior was included in the model, the effect of drinking style on DV was no longer significant. Substantial path differences for males and females were observed. Conclusions: The current study examined adolescent drinking style as a potential mediator between childhood victimization and DV. Drinking style was associated with DV for males and females and mediated the relationship between childhood victimization and DV. The relationship between drinking style and DV appeared to reflect adolescents' propensity for problem behavior. Variations in males' and females' pathways to DV were observed. The implications of these findings are discussed. PMID:21683037

Injuries constitute a major public health problem. Millions of people are injured each year, and acute drinking is a well-known risk factor for injuries. Research suggests that acknowledgment of alcohol as a factor in an injury enhances willingness to change drinking behavior, possibly because the patient becomes aware of the negative consequences of their drinking. This study aims to investigate the prevalence of acute alcohol consumption (drinking before the event) among injury patients and to examine the importance of factors potentially associated with motivation to reduce alcohol consumption among these patients. All patients aged 18-69 years were requested to answer alcohol-related questions on a touchscreen computer. Fifteen percent of injured patients were categorized as acute drinkers, and of these, 64% reported that their injury was connected to alcohol. There were significant differences for all sociodemographic and drinking characteristics between acute drinkers and nonacute drinkers. Acute drinkers were categorized as risky drinkers to a much higher extent than nonacute drinkers. Acute drinkers had a considerably higher average weekly alcohol consumption and engaged far more frequently in heavy episodic drinking than nonacute drinkers. Acute drinkers were motivated to reduce their alcohol intake to a greater extent than nonacute drinkers; 51% were in the action, preparation, and contemplation stages, compared with 19% of the nonacute drinkers. Acute drinkers had considerably more detrimental alcohol consumption than nonacute drinkers, and the acute drinkers were more motivated to reduce their drinking than the nonacute drinkers.

Background Mixing alcohol with energy drinks is associated with heavier drinking and related problems among college students. However, little is known about how high school drinkers who mix alcohol with energy drinks (AmED) compare to those who do not (AwoED). This study compares high school AmED and AwoED users on their alcohol use during middle and high school, as well as key domains of functioning in high school. Methods Two surveys were conducted three years apart in adolescents initially recruited from 16 middle schools in Southern California. The analytic sample consists of 696 past month drinkers. Multivariable models compared AmED and AwoED users on alcohol use, mental health, social functioning, academic orientation, delinquency and other substance use at age 17, and on their alcohol use and related cognitions at age 14. Results AmED was reported by 13% of past month drinkers. AmED and AwoED users did not differ on alcohol use or cognitions in middle school, but AmED users drank more often, more heavily, and reported more negative consequences in high school. AmED users were also more likely to report poor grades, delinquent behavior, substance use-related unsafe driving, public intoxication, and drug use than AwoED users in high school. Group differences were not found on mental health, social functioning, or academic aspirations. Conclusions AmED use is common among high school drinkers. The higher risk behavioral profile of these young AmED users, which includes drug use and substance use-related unsafe driving, is a significant cause for concern and warrants further attention.

Evidence suggests that noradrenergic signaling may play a role in mediating alcohol-drinking behavior in both rodents and humans. We have investigated this possibility by administering clonidine to alcohol-drinking rats selectively bred for alcohol preference (P line). Clonidine is an α2-adrenergic receptor agonist which, at low doses, inhibits noradrenergic signaling by decreasing norepinephrine release from presynaptic noradrenergic neurons. Adult male P rats were given 24 h access to food and water and scheduled access to a 15% (v/v) alcohol solution for 2 h daily. Rats received intra-peritoneal (IP) injections with clonidine (0, 10, 20, 40, or 80 μg/kg body weight [BW], 10-11 rats/treatment group) once/day at 30 min prior to onset of the daily 2 h alcohol access period for 2 consecutive days. Clonidine, in doses of 40 or 80 μg/kg BW, significantly reduced alcohol intake on both days of treatment (p<0.001). Two weeks later, rats were treated with clonidine for 5 consecutive days and clonidine, in doses of 40 or 80 μg/kg BW, reduced alcohol intake on all 5 treatment days (p < 0.001). Clonidine did not alter water consumption during the daily 2 h free-choice between alcohol and water. In a separate group of male P rats, clonidine (40 μg/kg BW) suppressed intake of a saccharin solution (0.04 g/L). These results are consistent with and complement our previous findings that the α1-adrenergic receptor antagonist, prazosin, decreases voluntary alcohol drinking in alcohol-preferring rats, but suggests that effects of clonidine may not be specific for alcohol. The results suggest that although activation of the noradrenergic system plays an important role in mediating voluntary alcohol drinking, care is needed in selecting which drugs to use to suppress central noradrenergic signaling in order to maximize the selectivity of the drugs for treating alcohol-use disorders.

Research has demonstrated a relation between alcohol use and engaging in high-risk sexual behaviors. Alcohol use, especially binge drinking, has been linked to a host of problems including high-risk sexual behavior, date rape, and academic problems. As such, the purpose of this study was to provide a descriptive profile of alcohol consumption among adolescents and to examine the relations of alcohol use (lifetime, current, binge) with sexual activity variables (sexual initiation, multiple sex partners, condom use, and pregnancy) among adolescents completing the 1993-1999 Youth Risk Behavior Survey. Analysis showed alcohol use was associated with high-risk sexual activity. Binge drinking had stronger relations with sexual activity variables than lifetime use and current use of alcohol. This result is of particular concern, in that binge drinking has been implicated in many problem behaviors. As such, it is of great importance to intervene in the high-risk practices of adolescents before problems occur.

We evaluated the association between residential exposure to outdoor alcohol advertising and current problem drinking among 139 African American women aged 21 to 49 years in Central Harlem, New York City. We found that exposure to advertisements was positively related to problem drinking (13% greater odds), even after we controlled for a family history of alcohol problems and socioeconomic status. The results suggest that the density of alcohol advertisements in predominantly African American neighborhoods may add to problem drinking behavior of their residents.

OBJECTIVES: To investigate the hypothesis that exposure to alcohol consumption in movies affects the likelihood that low-risk adolescents will start to drink alcohol. METHODS: Longitudinal study of 2346 adolescent never drinkers who also reported at baseline intent to not to do so in the next 12 months (mean age 12.9 years, SD = 1.08). Recruitment was carried out in 2009 and 2010 in 112 state-funded schools in Germany, Iceland, Italy, Netherlands, Poland, and Scotland. Exposure to movie alcohol consumption was estimated from 250 top-grossing movies in each country in the years 2004 to 2009. Multilevel mixed-effects Poisson regressions assessed the relationship between baseline exposure to movie alcohol consumption and initiation of trying alcohol, and binge drinking (≥ 5 consecutive drinks) at follow-up. RESULTS: Overall, 40% of the sample initiated alcohol use and 6% initiated binge drinking by follow-up. Estimated mean exposure to movie alcohol consumption was 3653 (SD = 2448) occurrences. After age, gender, family affluence, school performance, TV screen time, personality characteristics, and drinking behavior of peers, parents, and siblings were controlled for, exposure to each additional 1000 movie alcohol occurrences was significantly associated with increased relative risk for trying alcohol, incidence rate ratio = 1.05 (95% confidence interval, 1.02–1.08; P = .003), and for binge drinking, incidence rate ratio = 1.13 (95% confidence interval, 1.06–1.20; P < .001). CONCLUSIONS: Seeing alcohol depictions in movies is an independent predictor of drinking initiation, particularly for more risky patterns of drinking. This result was shown in a heterogeneous sample of European youths who had a low affinity for drinking alcohol at the time of exposure. PMID:24799536

Family factors have been widely implicated in the development of adolescent drinking behaviors. These include parental attachment and parental rules concerning drinking behaviors. Moreover, throughout adolescence attachment to parents gives way to attachment to peers, and parental rules about alcohol use become less strict. The present study examined the relationship between parental and peer attachment, parental rules on drinking and alcohol use in a large sample (n = 1,724) of adolescents in the United Kingdom. Controlling for school grade (proxy for age), sex and the non-independence of respondents (clustering at school level) results showed that scores on a parental rules on drinking questionnaire were a significant statistical predictor when comparing moderate drinkers and abstainers, as well as moderate drinkers and problematic drinkers. Scores on both attachment scales were also significant, but only in the comparison between moderate and problematic drinkers, with lower attachment to parents and higher attachment to peers associated with problematic drinking.

Background There has been a dramatic rise in the consumption of alcohol mixed with energy drinks (AmED) in social drinkers. It has been suggested that AmED beverages might lead individuals to drink greater quantities of alcohol. This experiment was designed to investigate if the consumption of AmED would alter alcohol priming (i.e., increasing ratings of wanting another drink) compared with alcohol alone. Methods Participants (n = 80) of equal gender attended one session where they were randomly assigned to receive one of 4 doses (0.91 ml/kg vodka, 1.82 ml/kg energy drink, 0.91 ml/kg vodka mixed with 1.82 ml/kg energy drink (AmED), or a placebo beverage). Alcohol-induced priming of the motivation to drink was assessed by self-reported ratings on the Desire-for-Drug questionnaire. Results The priming dose of alcohol increased the subjective ratings of “desire” for more alcohol, consistent with previous research that small doses of alcohol can increase the motivation to drink. Furthermore, higher desire ratings over time were observed with AmED compared to alcohol alone. Finally, ratings of liking the drink were similar for the alcohol and AmED conditions. Conclusions An energy drink may elicit increased alcohol priming. This study provides laboratory evidence that AmED beverages may lead to greater motivation to drink versus the same amount of alcohol consumed alone. PMID:22724427

Alcoholic beverages have been used throughout American history but their use has always been controversial. Ethyl alcohol is one of the few alcohols man is able to drink, although it is never full strength. The fermentation process is used to manufacture alcoholic beverages. Wines are made from a variety of fruits. Beer is made from yeast and a…

Excessive alcohol use is risk factor for a wide range of health and social problems including liver cirrhosis, certain cancers, depression, motor vehicle crashes, and violence. Alcohol use during pregnancy can lead to fetal alcohol spectrum disorders (FASDs) and other adverse birth outcomes . Community studies estimate that as many as 2% to 5% of first grade students in the United States might have an FASD, which include physical, behavioral, or learning impairments. In 2005, the Surgeon General reissued an advisory urging women who are or might be pregnant to abstain from alcohol consumption to eliminate the risk for FASDs or other negative birth outcomes. To estimate current prevalences of any alcohol use and binge drinking (consuming four or more drinks on an occasion) among pregnant and nonpregnant women aged 18-44 years in the United States, CDC analyzed 2011-2013 Behavioral Risk Factor Surveillance System (BRFSS) data. Among pregnant women, the prevalences of any alcohol use and binge drinking in the past 30 days were 10.2% and 3.1%, respectively. Among nonpregnant women, the prevalences of any alcohol use and binge drinking in the past 30 days were 53.6% and 18.2%, respectively. Among binge drinkers, pregnant women reported a significantly higher frequency of binge drinking than nonpregnant women (4.6 and 3.1 episodes, respectively); the largest amount consumed during binge drinking was also higher among pregnant women than nonpregnant women (7.5 versus 6.0 drinks), although this difference was not statistically significant. Implementation of evidence-based clinical and community-level strategies would be expected to reduce binge drinking among pregnant women and women of childbearing age, and any alcohol consumption among women who are or might be pregnant. Healthcare professionals can support these efforts by implementing alcohol screening and brief interventions in their primary care practices, and informing women that there is no known safe level of

Individuals who drink alcohol for the explicit motive of facilitating or enhancing sex may be more likely to engage in risky sexual behavior, including having sex under the influence of alcohol. However, efforts to assess sexual motives for drinking have been very limited to date. We examined the psychometric properties of a 5-item measure of sexual motives for drinking (SMD) in a sample of HIV-positive heavy drinking men who have sex with men. Findings provided excellent support for the scale's internal consistency and concurrent validity with a well-established measure of sexual alcohol expectancies (SAEs). Good discriminant validity was also established, as SMDs were correlated with other drinking motives but uniquely predicted the proportion of sex acts occurring under the influence of alcohol and other drugs, over-and-above other drinking motives and SAEs. SMDs were not significantly associated with unprotected anal intercourse. Adjusting for alcohol problem severity, higher SMDs were associated with lower willingness to consider changing drinking. Results suggest this measure of SMDs exhibits sound psychometric properties and may be useful in studies examining the association between alcohol use and sexual behavior. PMID:25134043

Alcohol consumption frequency and volume are known to be related to health problems among drinkers. Most of the existing literature that analyses regional variation in drinking behaviour uses measures of consumption that relate only to volume, such as 'binge drinking'. This study compares the regional association of alcohol consumption using measures of drinking frequency (daily drinking) and volume (binge drinking) using a nationally representative sample of residents using the Health Survey for England, 2011-2013. Results suggest the presence of two differentiated drinking patterns with relevant policy implications. We find that people in northern regions are more likely to binge drink, whereas people in southern regions are more likely to drink on most days. Regression analysis shows that regional variation in binge drinking remains strong when taking into account individual and neighbourhood level controls. The findings provide support for regional targeting of interventions that aim to reduce the frequency as well as volume of drinking.

Teen binge drinking is associated with low frontal white matter integrity and increased risk of alcoholism in adulthood. This neuropathology may result from alcohol exposure or reflect a pre-existing condition in people prone to addiction. Here we used rodent models with documented clinical relevance to adolescent binge drinking and alcoholism in humans to test whether alcohol damages myelinated axons of the prefrontal cortex. In Experiment 1, outbred male Wistar rats self-administered sweetened alcohol or sweetened water intermittently for 2 weeks during early adolescence. In adulthood, drinking behavior was tested under nondependent conditions or after dependence induced by 1 month of alcohol vapor intoxication/withdrawal cycles, and prefrontal myelin was examined 1 month into abstinence. Adolescent binge drinking or adult dependence induction reduced the size of the anterior branches of the corpus callosum, i.e., forceps minor (CCFM), and this neuropathology correlated with higher relapse-like drinking in adulthood. Degraded myelin basic protein in the gray matter medial to the CCFM of binge rats indicated myelin was damaged on axons in the mPFC. In follow-up studies we found that binge drinking reduced myelin density in the mPFC in adolescent rats (Experiment 2) and heavier drinking predicted worse performance on the T-maze working memory task in adulthood (Experiment 3). These findings establish a causal role of voluntary alcohol on myelin and give insight into specific prefrontal axons that are both sensitive to alcohol and could contribute to the behavioral and cognitive impairments associated with early onset drinking and alcoholism.

Adolescent solitary drinking may represent an informative divergence from normative behavior, with important implications for understanding risk for alcohol-use disorders later in life. Within a self-medication framework, we hypothesized that solitary alcohol use would be associated with drinking in response to negative affect and that such a pattern of drinking would predict alcohol problems in young adulthood. We tested these predictions in a longitudinal study in which we examined whether solitary drinking in adolescence (ages 12-18) predicted alcohol-use disorders in young adulthood (age 25) in 466 alcohol-using teens recruited from clinical programs and 243 alcohol-using teens recruited from the community. Findings showed that solitary drinking was associated with drinking in response to negative affect during adolescence and predicted alcohol problems in young adulthood. Results indicate that drinking alone is an important type of alcohol-use behavior that increases risk for the escalation of alcohol use and the development of alcohol problems.

Objective: Sexual behavior that incurs increased risk for sexually transmitted infections and HIV incidence is associated with both heavy alcohol and marijuana use. Whereas detrimental effects of alcohol on increased sexual risk have been documented in event-level and laboratory studies, less is known about the combined use of alcohol and marijuana and their relative impact on sexual risk behavior. We examined the degree to which both heavy drinking and marijuana use were associated with condomless sexual intercourse with casual versus main partners in a sample of weekly marijuana smokers. Method: Participants reported substance use and sexual activity using a 60-day Timeline Followback interview method (n = 112). Results: Results of generalized estimating equations indicated that both alcohol and marijuana use were independently associated with greater odds of having sexual intercourse but were not associated with greater odds of unprotected sex with a casual partner. Heavy drinking on a given day was associated with increased odds of having casual protected sex. Using both substances synergistically increased the likelihood of unprotected sex with a main partner. Conclusions: Findings suggest that behaviors posing higher sexual risk (condomless intercourse or sex with casual partners) occur on days when alcohol use exceeds moderate drinking guidelines. Interventions designed to reduce sexual risk behaviors may need to specifically target heavy drinking alone or when used with marijuana. PMID:26751360

Underage drinking among American youth is a growing public concern. However, while extensive research has identified individual level predictors of this phenomenon, few studies have theorized and tested the effect of structural social forces on children's and youths' alcohol consumption. In an attempt to address this gap, we study the effects of residential environments on children's and youths' underage drinking (while accounting for personality and familial processes). Integrating informal social control and opportunity explanations of deviance, we first suggest that while neighborhood collective efficacy prevents adolescents' underage drinking, individuals' access to local alcohol retail shops encourages such behavior. Focusing on the interactive effects of communal opportunities and controls, we then suggest that high presence of alcohol outlets and sales in the neighborhood is likely to increase youths' probability of alcohol consumption in the absence of communal mechanisms of informal social control. We test our theoretical model using the unprecedented data design available in the PHDCN. Results from a series of multilevel logit models with robust standard errors reveal partial support for our hypotheses; specifically, we find that alcohol sales in a given neighborhood increase adolescents' alcohol use. In addition, while the direct effect of collective efficacy is insignificantly related to children's and youths' alcohol consumption, our models suggest that it significantly attenuates the effect of local alcohol retailers and sales on underage drinking.

Excessive alcohol consumption is a major public health problem worldwide. Although drinking habits are known to be inherited, few genes have been identified that are robustly linked to alcohol drinking. We conducted a genome-wide association metaanalysis and replication study among >105,000 individuals of European ancestry and identified β-Klotho (KLB) as a locus associated with alcohol consumption (rs11940694; P = 9.2 × 10(-12)). β-Klotho is an obligate coreceptor for the hormone FGF21, which is secreted from the liver and implicated in macronutrient preference in humans. We show that brain-specific β-Klotho KO mice have an increased alcohol preference and that FGF21 inhibits alcohol drinking by acting on the brain. These data suggest that a liver-brain endocrine axis may play an important role in the regulation of alcohol drinking behavior and provide a unique pharmacologic target for reducing alcohol consumption.

Alcohol-exposed pregnancy is a leading cause of preventable birth defects in the United States. This paper describes the motivational patterns that relate to risky drinking and ineffective contraception, two behaviors that can result in alcohol-exposed pregnancy. As part of an intervention study aimed at reducing alcohol-exposed pregnancy 124 women were recruited and reported demographic characteristics, readiness to change, stages of change, drinking, contraception, and sexual behavior history. Our results showed the following. Drinking: A significant positive correlation was found between the number of drinks consumed in 90 days and the Importance to reduce drinking (r = .23, p = .008). A significant negative correlation between number of drinks and confidence to reduce drinking (r = −.39, p = .000) was found as well. Significant differences were found in the total number of drinks consumed in 90 days between the five stages of change (F = (4,118), 3.12, p = .01). Women in Preparation reported drinking a significantly higher number of drinks than women in other stages of change. Contraception: There were significant negative correlations between ineffective contraception and Importance (r = −.38, p = .00), confidence (r = −.20, p = .02) and Readiness (r = −.43, p = .00) to use contraception effectively. Significant differences in contraception ineffectiveness were found for women in different stages of change (F = (4,115) 8.58, p = .000). Women in Precontemplation reported significantly higher levels of contraception ineffectiveness compared to women in other stages of change. Results show a clear relationship between higher alcohol consumption and higher levels of motivation to reduce drinking. In contrast, higher levels of ineffective contraception were related to lower levels of motivation to use contraception effectively. This suggests risky drinking may be better targeted with brief skills building interventions and ineffective contraception may

Binge drinking, a pattern associated with worse outcome, is becoming increasingly popular among youths, thus negatively impacting social life. To investigate drinking patterns and their underlying motives in Italian adolescents, the Alcohol Use Questionnaire and the Drinking Motive Questionnaire Revised Short Form were administered to 332 school-age teenagers (16-19 years; 139 girls, 193 boys) from a single Roman school, recruited at their classrooms through the intermediation of their teachers. Boys scored higher than girls on all drinking and binge measures. They also scored higher on the Enhancement, Social, and Conformity Drinking Motive Questionnaire-Revised Short Form subscales. Binge drinking scores positively correlated with gender, alcohol consumption, and with all Drinking Motive Questionnaire Revised Short Form subscales. In the two-step hierarchical model, Drinking Motive Questionnaire-Revised Short Form enhancement and conformity predicted alcohol use and Drinking Motive Questionnaire-Revised Short Form coping motives significantly predicted binge drinking. Binge drinking is prevalent among Italian adolescents, who mainly drink to enhance perceived positive effects of alcohol, conform to their social groups, and face their problems. Boys binge more than girls.

OBJECTIVE: To examine the appeal of "designer drinks" to young people. DESIGN: Qualitative and quantitative research comprising group discussions and questionnaire led interviews with young people accompanied by a self completion questionnaire. SETTINGS: Argyll and Clyde Health Board area, west Scotland. SUBJECTS: Eight groups aged 12-17 years; 824 aged 12-17 recruited by multistage cluster probability sample from the community health index. RESULTS: Young people were familiar with designer drinks, especially MD 20/20 and leading brands of strong white cider. Attitudes towards these drinks varied quite distinctly with age, clearly reflecting their attitudes towards and motivations for drinking in general. The brand imagery of designer drinks-in contrast with that of more mainstream drinks-matched many 14 and 15 year olds' perceptions and expectations of drinking. Popularity of designer drinks peaked between the ages of 13 and 16 while more conventional drinks showed a consistent increase in popularity with age. Consumption of designer drinks tended to be in less controlled circumstances and was associated with heavier alcohol intake and greater drunkenness. CONCLUSIONS: Designer drinks are a cause for concern. They appeal to young people, often more so than conventional drinks, and are particularly attractive to 14-16 year olds. Consumption of designer drinks is also associated with drinking in less controlled environments, heavier drinking, and greater drunkenness. There is a need for policy debate to assess the desirability of these drinks and the extent to which further controls on their marketing are required. PMID:9040387

Despite speculation that peers' alcohol-related content on social media sites (SMS) may influence the alcohol use behaviors of SMS frequenting college students, this relationship has not been investigated longitudinally. The current prospective study assesses the relationship between exposure to peers' alcohol-related SMS content and later-drinking among first-year college students. Among 408 first-year students, total exposure to peers' alcohol-related content on Facebook, Instagram, and Snapchat during the initial 6 weeks of college predicted alcohol consumption 6 months later. The rather robust relationship persisted even after students' and close friends drinking were accounted for, indicating that alcohol references on SMS do not simply reflect alcohol use behaviors that would otherwise be observed in the absence of SMS and be predictive of later alcohol use. Findings also illuminate important gender differences in the degree to which peers' alcohol-related SMS content influenced later drinking behavior as well as psychological mediators of this relationship. Among females, enhancement drinking motives and beliefs about the role of alcohol in the college experience fully mediated the relationship between SMS alcohol exposure and later drinking. Males, however, evidenced a much stronger predictive relationship between SMS alcohol exposure and second semester drinking, with this relationship only partially explained by perceptions of drinking norms, enhancement drinking motives, and beliefs about the role of alcohol in the college experience. Implications of these findings for college drinking prevention efforts and directions for future research are discussed.

Aims Universities are striving to raise funds, often attracting spectators by selling alcohol at campus events. This study evaluates the effect of a policy change on student drinking at a large western university that had historically banned alcohol on campus but transitioned to permitting the sale of alcohol in some of its facilities. Methods Surveys of student drinking and perceptions of other students' drinking were conducted before, during and after the policy change at the transition university (TU) and compared to similar data from a control university (CU). Surveys of student drinking at on-campus and off-campus venues and observations of alcohol service practices were also conducted. Results The policy change at the TU was introduced cautiously, and sales to underage drinkers were relatively well controlled. Despite this, student drinking rose initially, then declined after 1 year. Perceptions of the amount of drinking by other students increased slightly, but there was no overall measurable increase in student drinking during the first 3 years of the new policy. Conclusions The conservative TU policy—to sell alcohol only at select events and to control sales to minors—may have limited the impact of on-campus alcohol sales on student consumption. Although the study results did not find a stable increase in student drinking, they do not necessarily support the liberalization of campus alcohol policy, because the transition is still ‘in progress’ and the final outcome has not been evaluated.

Recent literature showed that expectancies or cognitions have been proposed as a major factor in influencing the amount of alcohol an individual consumes and the behavioral consequences following consumption. However, how alcohol expectancies influence alcohol consumption is unclear; this paper reports two studies of the relationship. Study I examined the relationship between alcohol consumption and alcohol-related positive and negative self-statements in 110 social drinkers. The results showed that, in a nondrinking situation, the alcohol expectancies and variables measuring consumption and alcohol-related problems were correlated. Also, subjects who perceived their "alcoholic sets" as negative consumed more than those who perceived theirs as positive. Study II investigated changes in self-statement responding in 8 light and 8 heavy drinkers in a "normal" pub drinking situation. The results showed that alcohol-dependent self-statements in the light drinkers were relatively stable across time and between drinking and nondrinking environments. However, the alcohol-dependent self-statements of heavy drinkers became more negative during the drinking session. Furthermore, the degree and nature of such changes appeared to be related to alcohol-associated problems and consumption.

Background Driving after the consumption of alcohol represents a significant problem globally. Individual prevention countermeasures such as personalized mobile apps aimed at preventing such behavior are widespread, but there is little research on their accuracy and evidence base. There has been no known assessment investigating the quality of such apps. Objective This study aimed to determine the quality and accuracy of apps for drink driving prevention by conducting a review and evaluation of relevant mobile apps. Methods A systematic app search was conducted following PRISMA guidelines. App quality was assessed using the Mobile App Rating Scale (MARS). Apps providing blood alcohol calculators (hereafter “calculators”) were reviewed against current alcohol advice for accuracy. Results A total of 58 apps (30 iOS and 28 Android) met inclusion criteria and were included in the final analysis. Drink driving prevention apps had significantly lower engagement and overall quality scores than alcohol management apps. Most calculators provided conservative blood alcohol content (BAC) time until sober calculations. None of the apps had been evaluated to determine their efficacy in changing either drinking or driving behaviors. Conclusions This novel study demonstrates that most drink driving prevention apps are not engaging and lack accuracy. They could be improved by increasing engagement features, such as gamification. Further research should examine the context and motivations for using apps to prevent driving after drinking in at-risk populations. Development of drink driving prevention apps should incorporate evidence-based information and guidance, lacking in current apps. PMID:27502956

The acute impairing effects of alcohol on inhibitory control are well-established, and these disinhibiting effects are thought to play a role in its abuse potential. Alcohol impairment of inhibitory control is typically assessed in the context of arbitrary cues, yet drinking environments are comprised of an array of alcohol-related cues that are thought to influence drinking behavior. Recent evidence suggests that alcohol-related stimuli reduce behavioral control in sober drinkers, suggesting that alcohol impairment of inhibitory control might be potentiated in the context of alcohol cues. The current study tested this hypothesis by examining performance on the attentional-bias behavioral activation (ABBA) task that measures the degree to which alcohol-related stimuli can reduce inhibition of inappropriate responses in a between-subjects design. Social drinkers (N=40) performed the task in a sober condition, and then again following placebo (0.0 g/kg) and a moderate dose of alcohol (0.65 g/kg) in counter-balanced order. Inhibitory failures were greater following alcohol images compared to neutral images in sober drinkers, replicating previous findings with the ABBA task. Moreover, alcohol-related cues exacerbated alcohol impairment of inhibitory control as evidenced by more pronounced alcohol-induced disinhibition following alcohol cues compared to neutral cues. Finally, regression analyses showed that greater alcohol-induced disinhibition following alcohol cues predicted greater self-reported alcohol consumption. These findings have important implications regarding factors contributing to binge or ‘loss of control’ drinking. That is, the additive effect of disrupted control mechanisms via both alcohol-cues and the pharmacological effects of the drug could compromise an individual’s control over ongoing alcohol consumption.

Alcohol consumption is largely associated with alterations in the extracellular glutamate concentrations in several brain reward regions. We recently showed that glutamate transporter 1 (GLT-1) is downregulated following chronic exposure to ethanol for 5 weeks in alcohol-preferring (P) rats and that upregulation of the GLT-1 levels in nucleus accumbens and prefrontal cortex results, in part, in attenuating ethanol consumption. Cystine glutamate antiporter (xCT) is also downregulated after chronic ethanol exposure in P rats, and its upregulation could be valuable in attenuating ethanol drinking. This study examines the effect of a synthetic compound, (R)-(-)-5-methyl-1-nicotinoyl-2-pyrazoline (MS-153), on ethanol drinking and expressions of GLT-1 and xCT in the amygdala and the hippocampus of P rats. P rats were exposed to continuous free-choice access to water, 15% and 30% ethanol, and food for 5 weeks, after which they received treatments of MS-153 or vehicle for 5 days. The results show that MS-153 treatment significantly reduces ethanol consumption. It was revealed that GLT-1 and xCT expressions were downregulated in both the amygdala and the hippocampus of ethanol-vehicle-treated rats (ethanol-vehicle group) compared with water-control animals. MS-153 treatment upregulated GLT-1 and xCT expressions in these brain regions. These findings demonstrate an important role for MS-153 in these glutamate transporters for the attenuation of ethanol-drinking behavior.

Alcohol use disorder commonly occurs in patients with schizophrenia and dramatically worsens their course. The atypical antipsychotic clozapine has been associated with reduced drinking in these patients, but its toxicity reduces its use. We have attempted to create a clozapine-like drug by combining agents that capture components of clozapine's pharmacologic action, including its weak dopamine D2 blockade and noradrenergic modulation. The current study assessed whether paliperidone, a dopamine D2 receptor and adrenergic alpha-2 receptor antagonist like clozapine, would attenuate alcohol drinking in the alcohol-preferring P rat and the Syrian golden hamster, and whether desipramine, a norepinephrine reuptake inhibitor, would potentiate the ability of paliperidone to attenuate alcohol drinking in the P rat and the Syrian golden hamster. Daily subcutaneous injections of paliperidone (5 mg/kg for the rat; 1 mg/kg for the hamster) over 20 days slightly and transiently attenuated initiation of alcohol consumption in both animals. Desipramine (3 mg/kg) or lower doses of paliperidone alone did not affect alcohol drinking. However, the combination of desipramine (3 mg/kg) and paliperidone essentially prevented initiation of alcohol drinking and acquisition of alcohol preference in the P rat (2.5 or 5 mg/kg), and almost as dramatically suppressed chronic alcohol intake and alcohol preference in the hamster (2.5 mg/kg). Taken together, the current data suggest that (1) the desipramine and paliperidone combination attenuates alcohol drinking in a synergistic manner, and (2) desipramine and paliperidone may serve as an effective new treatment for alcohol use disorder in patients with schizophrenia.

Drinking alcohol in moderation is often considered a health-conscious behavior, associated with improved cardiovascular and brain health. However, "moderate" amounts of alcohol include drinking 3-4 alcohol beverages in a day, which is closer to binge drinking and may do more harm than good. Here we examined how daily drinking of moderate-high alcohol alters the production of new neurons in the adult hippocampus. Male and female adult Sprague-Dawley rats were provided free access to a liquid replacement diet that was supplemented with either 4% ethanol or Maltodextrin for a period of 2 weeks. Proliferating cells were labeled with 5-bromo-2-deoxyuridine (BrdU) and the number of BrdU-positive cells in the hippocampus was assessed after the final day of drinking. A subset of rats was also exposed to a motor skill or associative learning task to examine the functional effects of alcohol consumption. The drinking regime resulted in an average blood alcohol concentration of approximately 0.08%, which is comparable to the human legal driving limit in many countries. This level of intoxication did not impair motor skill learning or function in either sex, nor did the alcohol consumption disrupt associative learning 2 days after drinking. Therefore, moderate alcohol consumption did not disrupt basic sensory, motor or learning processes. However, the number of cells produced in the dentate gyrus of the hippocampus was reduced by nearly 40%. Thus, even moderate consumption of alcohol for a relatively short period of time can have profound effects on structural plasticity in the adult brain.

Using a survey of drinkers (N = 1,634), we evaluated alternative explanations of heavy and binge drinking, driving under the influence (DUI), DUI arrests, speeding citations, and chargeable accidents. Explanations included socializing, short-term decision-making, unrealistic optimism, risk preferring behavior, and addiction. Most consistent relationships were between substance use and alcohol addiction and dependent variables for (1) binge drinking and (2) DUI episodes. Respondent characteristics (age, marital and employment status, race, etc.) had important roles for DUI arrests. Drinker-drivers and those arrested for DUI are partially overlapping groups with implications for treatment and policies detecting and incapacitating persons from drinking and driving.

Several serotonin uptake inhibitors, including the long-acting fluoxetine, have been found to decrease alcohol intake in moderately dependent alcoholics. While the mechanism of their effect is not fully elucidated, a previous study with citalopram indicated that decreased desire to drink may be an important factor. Therefore, we tested fluoxetine effects on alcohol intake and desire to drink in a placebo-controlled study. Subjects, recruited by advertisement, were mildly/moderately dependent alcoholics (12 male, four female, aged 19-59 years, healthy, non-depressed) who did not believe they had a drinking problem and were not requesting treatment. After a 1 week baseline they received, single-blind, 2 weeks placebo followed by 2 weeks fluoxetine 60 mg/day. As out-patients, subjects recorded daily standard drinks (13.6 g ethanol) and rated interest, desire, craving and liking for alcohol biweekly. Each out-patient period was immediately followed by a double-blind experimental drinking session. Out-patient daily drinks slightly decreased during fluoxetine to 6.6 +/- 0.9 (mean +/- S.E.M.) compared with during placebo (7.16 +/- 0.95, p = 0.07, N.S.) and baseline (7.18 +/- 1.0, p > 0.1, N.S.). Desire, interest and craving for alcohol decreased during fluoxetine vs placebo baseline (p < 0.05), but not vs placebo. Appetite loss and decrease in food intake (p < 0.01, fluoxetine vs placebo) correlated with each other (r = 0.91, p < 0.01) but neither correlated with decrease in alcohol intake (appetite: r = 0.26, N.S.; food intake: r = 0.22, N.S.). Weight loss occurred during fluoxetine (p < 0.05 vs placebo) but did not correlate with decrease in alcohol intake (r = 0.1, N.S.). In the experimental drinking sessions after placebo and fluoxetine treatments subjects rated their desire for each of 18 mini-drinks (each one-third of a standard drink) offered at 5 min intervals. Fluoxetine decreased desire to drink throughout the sessions; both mean and maximum desire ratings were

Purpose This study examined relationships between energy drink consumption and problem behaviors among adolescents and emerging adults. It was hypothesized that frequent consumption of energy drinks would be positively associated with substance abuse and other risky behaviors and that these relationships would be moderated by race. Methods Cross-sectional, self-report survey data were collected from 602 Western New York undergraduate students in the spring of 2006. Differences in problem behaviors by frequency of energy drink consumption were assessed with multivariate linear and logistic regressions, controlling for gender, race, age, parental education, and college grade point average. Follow-up regressions were conducted to test for a moderating effect of race. Results Frequency of energy drink consumption was positively associated with marijuana use, sexual risk-taking, fighting, seatbelt omission, and taking risks on a dare for the sample as a whole, and associated with smoking, drinking, alcohol problems, and illicit prescription drug use for white students but not for black students. Conclusions These findings suggest that energy drink consumption is closely associated with a problem behavior syndrome, particularly among whites. Frequent consumption of energy drinks may serve as a useful screening indicator to identify students at risk for substance use and/or other health-compromising behavior. PMID:18848678

Apart from individual alcohol drinking behavior, the context or places where people drink play a significant role in HIV transmission risk. In this paper, we review the research that has been conducted on alcohol venues to identify the social and structural factors (e.g., social norms, sexual behavior) that are associated with HIV risk in these places, to review HIV prevention interventions based in alcohol venues, and to discuss appropriate methodologies for alcohol venue research. Alcohol venues are defined here as places that sell or serve alcohol for onsite consumption, including bars, bottle stores, nightclubs, wine shops, and informal shebeens. Despite the many established HIV risk factors at play in alcohol venues, limited prevention strategies have been implemented in such places. A total of 11 HIV prevention interventions or programs were identified. HIV prevention interventions in alcohol venues may be conducted at the individual, social, or structural level. However, multilevel interventions that target more than one level appear to lead to the most sustainable behavior change. Strategies to incorporate alcohol venues in biomedical prevention strategies including antiretroviral therapy for alcohol users are also discussed. PMID:26099244

Background Alcohol-related blackouts are periods of amnesia that reflect the failure of the brain to record memories of what transpires while drinking. This paper examined the incidence, predictors, and behavioral correlates of blackouts among emerging adults and examined whether questions about blackouts could serve as better markers of risk for other alcohol related harms than questions about levels of consumption. Methods In 2012-2013, 1,463 (68%) of 2,140 respondents one-year past high school reported having consumed alcohol. They were asked whether, in the past six months because of drinking, they forgot where they were or what they did. The survey also explored demographics, substance use behaviors, and other alcohol-related problems in the past six months. Chi square and logistic regression analyses explored bivariate and multivariate predictors of blackouts and other alcohol-related problems. Results Twenty percent of respondents who ever drank alcohol reported a blackout in the past six months. Blackouts were more prevalent among females and those who, in the past 30 days, used multiple drugs, more frequently binged, were drunk, smoked, had lower body weight, and lived in college dorms. After controlling for drinking levels, having a blackout was the strongest independent predictor of most other alcohol problems examined, including in the past six months because of drinking, missing class or work, getting behind in work or school, doing something respondents later regretted, arguing with friends, experiencing an overdose, and total number of alcohol problems reported. It was also an independent predictor of hangovers, damaging property, getting hurt, and trouble with police. Conclusion Because blackouts indicate drinking at levels that result in significant cognitive and behavioral impairment, questions about blackouts could serve as important, simple screeners for the risk of experiencing other alcohol related harms.

Alcohol use disorders (AUDs) are a major public health issue and have an enormous social and economic burden in developed, developing, and third-world countries. Current pharmacotherapies for treating AUDs suffer from deleterious side effects and are only effective in preventing relapse in a subset of individuals. This signifies an essential need for improved medications to reduce heavy episodic drinking and alcohol-related problems. Growing literature has provided support for the use of anticonvulsants in suppressing symptoms induced by alcohol withdrawal. Emerging clinical and preclinical evidence suggests that a number of well-tolerated anticonvulsants may also decrease alcohol drinking. This review will focus on recent evidence supporting the efficacy of novel anticonvulsants in reducing voluntary alcohol consumption in rodent models. The data demonstrate that anticonvulsants reduce drinking in standard home cage two-bottle choice paradigms, self-administration of alcohol in operant chambers, and cue- and stress-induced reinstatement of alcohol seeking behaviors in rats and mice. This review also highlights evidence that some anticonvulsants were only moderately effective in reducing drinking in select strains of rodents or models. This suggests that genetics, possible neuroadaptations, or the pharmacological target affect the ability of anticonvulsants to attenuate alcohol consumption. Nonetheless, anticonvulsants are relatively safe, have little abuse potential, and can work in combination with other drugs. The results from these preclinical and clinical studies provide compelling evidence that anticonvulsants are a promising class of medication for the treatment of AUDs.

The objective of this study is to describe energy drink consumption and health behaviors among college students attending a predominantly minority university. Undergraduate and graduate students attending a private, minority-serving university were invited to participate in an online survey between September 2009 and August 2010. Out of 2,500 students, 407 participated yielding a response of 16 %. Analysis assessed energy drink consumption as well as participation in sport activities and high-risk behaviors. Energy drink consumption is significantly related with drinking alcohol to inebriation and driving (r = .14, p < .05) and to riding with a drunk driver (r = .15, p < .05). Athletes were more likely to engage in drinking alcohol to inebriation and driving F (1, 186) = 6.12, p < .02. Energy drink consumption is a common practice among racial minority university students. Tailored health promotion strategies and interventions are needed to address misconceptions of energy drink and alcohol mixing.

A structural equation model examined sexual enhancement alcohol expectancies, heavy episodic drinking (HED), and risky sexual behavior as correlates of alcohol-involved rape in a sample of 353 college women. Prevalence of alcohol-involved rape was 15.6%. Sexual enhancement alcohol expectancies were indirectly associated with alcohol-involved rape via increased levels of HED, greater likelihood of sex while intoxicated, and number of sex partners. All forms of risky behavior were associated with alcohol-involved rape although HED had the strongest relationship. Findings suggest continued focus on women's positive alcohol expectancies and HED as risk factors for alcohol-involved rape. Implications for intervention will be discussed.

This study examined the association between paternal alcoholism and 12-month infant temperament and 18-month behavior problems. The role of associated parental psychopathology and maternal drinking in exacerbating risk for maladaptive behavioral outcomes was also examined. Participants were 213 families (102 control families, 94 paternal alcoholic families, and 17 families with alcoholic fathers and heavy drinking mothers) who were assessed when their child was 12 months old and reassessed again when their child was 18 months old. Infants of alcoholics displayed marginally more stubborn/persistent temperaments at 12 months of age, but significantly more internalizing problems at 18 months. Analyses suggested that internalizing problems in the infants of alcoholics could be attributed to the paternal depression concomitant with paternal alcoholism. In addition, an interaction was observed, indicating that paternal alcohol problems predicted 18-month externalizing problems among families with low maternal depression, but not among families with high maternal depression. Children of depressed mothers exhibited uniformly higher externalizing scores, but were not further impacted by paternal alcohol problems. However, children of nondepressed mothers were adversely affected by fathers’ drinking as reflected by higher externalizing behavior scores. The results highlight the necessity of addressing the overall contextual risks that occur with paternal alcoholism in studies of the development of children in alcoholic families. PMID:19436770

We examined direct and indirect pathways between adverse environmental exposures during gestation and childhood and drinking in mid-adolescence. Mothers and their offspring (n = 917 mother/child dyads) were followed prospectively from second trimester to a 16-year follow-up assessment. Interim assessments occurred at delivery, 6, 10, and 14 years. Adverse environmental factors included gestational exposures to alcohol, tobacco, and marijuana, exposures to childhood maltreatment and violence, maternal psychological symptoms, parenting practices, economic and home environments, and demographic characteristics of the mother and child. Indirect effects of early child behavioral characteristics including externalizing, internalizing activity, attention, and impulsivity were also examined. Polytomous logistic regression analyses were used to evaluate direct effects of adverse environmental exposures with level of adolescent drinking. Structural equation modeling (SEM) was applied to simultaneously estimate the relation between early adversity variables, childhood characteristics, and drinking level at age 16 while controlling for significant covariates. Level of drinking among the adolescent offspring was directly predicted by prenatal exposure to alcohol, less parental strictness, and exposures to maltreatment and violence during childhood. Whites and offspring with older mothers were more likely to drink at higher levels. There was a significant indirect effect between childhood exposure to violence and adolescent drinking via childhood externalizing behavior problems. All other hypothesized indirect pathways were not significant. Thus most of the early adversity measures directly predicted adolescent drinking and did not operate via childhood behavioral dysregulation characteristics. These results highlight the importance of adverse environmental exposures on pathways to adolescent drinking. PMID:26994529
Background Reducing harm in drinking environments is a growing priority for European alcohol policy yet few studies have explored nightlife drinking behaviours. This study examines alcohol consumption and blood alcohol concentration (BAC) in drinking environments in four European cities. Methods A short questionnaire was implemented among 838 drinkers aged 16-35 in drinking environments in four European cities, in the Netherlands, Slovenia, Spain and the UK. Questions included self-reported alcohol use before interview and expected consumption over the remainder of the night. Breathalyser tests were used to measured breath alcohol concentration (converted to BAC) at interview. Results Most participants in the Dutch (56.2%), Spanish (59.6%) and British (61.4%) samples had preloaded (cf Slovenia 34.8%). In those drinking < 3 h at interview, there were no differences in BAC by gender or nationality. In UK participants, BAC increased significantly in those who had been drinking longer, reaching 0.13% (median) in females and 0.17% in males drinking > 5 h. In other nationalities, BAC increases were less pronounced or absent. High BAC (> 0.08%) was associated with being male, aged > 19, British and having consumed spirits. In all cities most participants intended to drink enough alcohol to constitute binge drinking. Conclusions Different models of drinking behaviour are seen in different nightlife settings. Here, the UK sample was typified by continued increases in inebriation compared with steady, more moderate intoxication elsewhere. With the former being associated with higher health risks, European alcohol policy must work to deter this form of nightlife. PMID:22151744

The present study examined the unique contributions of protective behavioral strategies and social norms in predicting alcohol-related outcomes. Participants were 363 students from a large public university in the Midwest who reported at least one binge-drinking episode (5+/4+ drinks for men/women in one sitting) in the past 30 days. Data were collected 1/2010-3/2011. We used SEM to test models where protective behavioral strategies (PBS) and social norms were predictors of both alcohol use and alcohol-related problems, after controlling for the effects of gender. Both PBS and descriptive norms had relationships with alcohol use. PBS also had a relationship with alcohol-related problems. Overall, the findings suggest that PBS and social norms have unique associations with distinct alcohol-related outcomes.
Women drinkers are on the increase, in recent 20 years, according to greater participation of women in public affairs and the change of life style and so on. So, the consciousness or attitude of drinking or alcoholic beverages among women have been changed by the new customs of drinking. In this paper the relationship between women drinking behavior and their consciousness of drinking or life events, was investigated statistically using the data of sending questionnaires concerning about drinking behavior, consciousness and drinking history in Kusatsu city. The subject of investigation was 4,105 women who were aged 30 years and more, and 1,650 answers were available. Then the following findings were obtained; 1) The pattern of consumption of alcoholic beverages changed fairly from 1960, but in recent years, it seems to keep balance and yearly consumption of pure alcohol per adult has leveled off about 8 l. 2) Distribution of PAC (Pure Alcohol Consumption per year) of women exceeding the limit of a liter per year was against the logarithmic normal curve. The median value of PAC of women in Kusatsu was estimated about 0.55 l, and it seemed to be smaller than that of men. QFI (Quantity-Frequency Index) of women was large among those who were full-time workers being in their thirties and forties, and had mother of regular drinker who drank once and more a week. 3) The estimated ratio of excessive drinkers among women by adopting Ledermann's model was larger than the practical ratio. For estimating the women excessive drinkers accurately, it is necessary to use exact P.A.C. of women. 4) The 20 opinions concerning with drinking or alcoholic beverages were grouped into four basic consciousness by using the method of factor analysis. The 1st was 'necessity or values' of drinking, the 2nd was 'method or manner' for taking the pleasure of drinking and of correct drinking, the 3rd was 'regulation' of alcoholic slot machine, minor drinking or drunk and the 4th was 'harmfulness

Adolescence is a developmental period when physical and cognitive abilities are optimized, when social skills are consolidated, and when sexuality, adolescent behaviors, and frontal cortical functions mature to adult levels. Adolescents also have unique responses to alcohol compared with adults, being less sensitive to ethanol sedative–motor responses that most likely contribute to binge drinking and blackouts. Population studies find that an early age of drinking onset correlates with increased lifetime risks for the development of alcohol dependence, violence, and injuries. Brain synapses, myelination, and neural circuits mature in adolescence to adult levels in parallel with increased reflection on the consequence of actions and reduced impulsivity and thrill seeking. Alcohol binge drinking could alter human development, but variations in genetics, peer groups, family structure, early life experiences, and the emergence of psychopathology in humans confound studies. As adolescence is common to mammalian species, preclinical models of binge drinking provide insight into the direct impact of alcohol on adolescent development. This review relates human findings to basic science studies, particularly the preclinical studies of the Neurobiology of Adolescent Drinking in Adulthood (NADIA) Consortium. These studies focus on persistent adult changes in neurobiology and behavior following adolescent intermittent ethanol (AIE), a model of underage drinking. NADIA studies and others find that AIE results in the following: increases in adult alcohol drinking, disinhibition, and social anxiety; altered adult synapses, cognition, and sleep; reduced adult neurogenesis, cholinergic, and serotonergic neurons; and increased neuroimmune gene expression and epigenetic modifiers of gene expression. Many of these effects are specific to adolescents and not found in parallel adult studies. AIE can cause a persistence of adolescent-like synaptic physiology, behavior, and sensitivity

Population studies find that an early age of drinking onset correlates with increased lifetime risks for the development of alcohol dependence, violence, and injuries. Brain synapses, myelination, and neural circuits mature in adolescence to adult levels in parallel with increased reflection on the consequence of actions and reduced impulsivity and thrill seeking. Alcohol binge drinking could alter human development, but variations in genetics, peer groups, family structure, early life experiences, and the emergence of psychopathology in humans confound studies. As adolescence is common to mammalian species, preclinical models of binge drinking provide insight into the direct impact of alcohol on adolescent development. This review relates human findings to basic science studies, particularly the preclinical studies of the Neurobiology of Adolescent Drinking in Adulthood (NADIA) Consortium. These studies focus on persistent adult changes in neurobiology and behavior following adolescent intermittent ethanol (AIE), a model of underage drinking. NADIA studies and others find that AIE results in the following: increases in adult alcohol drinking, disinhibition, and social anxiety; altered adult synapses, cognition, and sleep; reduced adult neurogenesis, cholinergic, and serotonergic neurons; and increased neuroimmune gene expression and epigenetic modifiers of gene expression. Many of these effects are specific to adolescents and not found in parallel adult studies. AIE can cause a persistence of adolescent-like synaptic physiology, behavior, and sensitivity to

Research and theory suggest that romantic couple members are motivated to drink to cope with interpersonal distress. Additionally, this behavior and its consequences appear to be differentially associated with insecure attachment styles. However, no research has directly examined drinking to cope that is specific to relationship problems, or with relationship-specific drinking outcomes. Based on alcohol motivation and attachment theories, the current study examines relationship-specific drinking-to-cope processes over the early years of marriage. Specifically, it was hypothesized that drinking to cope with a relationship problem would mediate the associations between insecure attachment styles (i.e., anxious and avoidant) and frequencies of drinking with and apart from one's partner and marital alcohol problems in married couples. Multilevel models were tested via the actor-partner interdependence model using reports of both members of 470 couples over the first nine years of marriage. As expected, relationship-specific drinking-to-cope motives mediated the effects of actor anxious attachment on drinking apart from one's partner and on marital alcohol problems, but, unexpectedly, not on drinking with the partner. No mediated effects were found for attachment avoidance. Results suggest that anxious (but not avoidant) individuals are motivated to use alcohol to cope specifically with relationship problems in certain contexts, which may exacerbate relationship difficulties associated with attachment anxiety. Implications for theory and future research on relationship-motivated drinking are discussed.

The alcohol intake of twenty adult Long-Evans male rats was recorded before, during and after rapid eye movement sleep (REM) deprivation produced with the flowerpot technique modified by using a cuff pedestal and an electrified grid floor instead of water. The alcohol intake reached a steady level of 2.8 g/kg/day in the 3 weeks before REM deprivation. During seven REM-sleep deprivation days the alcohol intake was significantly elevated, finally increasing to 3.7 g/kg/day. A rebound decrease in alcohol drinking was then observed during the "REM-rebound" phase immediately after the termination of REM-sleep deprivation. The results suggest a possible vicious circle of REM-sleep deprivation increasing alcohol drinking and alcohol intake causing REM-sleep deprivation.

Summary paragraph Binge alcohol drinking is a tremendous public health problem because it leads to the development of numerous pathologies including alcohol abuse, and anxiety1–4. It is thought to do so by hijacking brain systems that regulate stress and reward, including neuropeptide Y (NPY) and corticotropin–releasing factor (CRF). The central actions of NPY and CRF play opposing functional roles in the regulation of emotional and reward–seeking behaviors; therefore, dysfunctional interactions between these peptidergic systems could play a role in the development of these pathologies. Here, we used converging physiological, pharmacological, and chemogenetic approaches to identify a precise neural mechanism in the bed nucleus of the stria terminalis (BNST), a limbic brain region involved in pathological reward and anxiety behaviors, underlying the interactions between NPY and CRF in the regulation of binge alcohol drinking in both mice and monkeys. We found that NPY Y1 receptor (Y1R) activation in the BNST suppressed binge alcohol drinking by enhancing inhibitory synaptic transmission specifically in CRF neurons via a novel, Gi-mediated, PKA-dependent postsynaptic mechanism. Further, chronic alcohol drinking led to persistent alterations in Y1R function in the BNST of both mice and monkeys, highlighting the enduring, conserved nature of this effect across mammalian species. Together, these data provide both a cellular locus and signaling framework for the development of novel therapeutics for treatment of neuropsychiatric diseases, including alcohol use disorders.

Experimental animal models are critical for understanding the genetic, environmental and neurobiological underpinnings of alcohol use disorders. Limited studies investigate alcohol-induced effects on behavior using free-choice paradigms. The aims of the present experiment were to study voluntary alcohol intake using a modified intermittent access paradigm, investigate the effects of voluntary alcohol intake on behavioral profiles in water- and alcohol-drinking rats, and select extreme low- and high-drinking animals for a more detailed behavioral characterization. Sixty outbred male Wistar rats were randomized into water and alcohol groups. Behavioral profiles in the multivariate concentric square field™ (MCSF) test were assessed prior to and after voluntary alcohol intake. The animals had intermittent access to 20% alcohol and water for three consecutive days per week for seven weeks. The results revealed increased alcohol intake over time. No major alcohol-induced differences on behavior profiles were found when comparing water- and alcohol-drinking animals. The high-drinking animals displayed an alcohol deprivation effect, which was not found in the low-drinking animals. High-drinking rats had lower risk-taking behavior prior to alcohol access and lower anxiety-like behavior after voluntary alcohol intake compared to low-drinking rats. In conclusion, the modified intermittent access paradigm may be useful for pharmacological manipulation of alcohol intake. With regard to behavior, the present findings highlights the importance of studying subgroup-dependent differences and add to the complexity of individual differences in behavioral traits of relevance to the vulnerability for excessive alcohol intake.

Objective: The present study investigates risk behaviors, sleep habits, and mental health factors associated with caffeinated beverage use in young adults. Materials and Methods: Students from a midsize private university (n = 159) completed a 15-minute anonymous questionnaire, including questions on risk behaviors, sleep habits, alcohol, and caffeine consumption. We compared behaviors between the top ∼15% ("high end") of energy drink users (≥3/month) and coffee users (≥16/month) to those with less frequent or no caffeine consumption. Results: Caffeine consumption was frequent among young adults. In the last month, 36% of students had an energy drink, 69% had coffee or espresso, and 86% reported having any caffeine; however, the majority of students were unaware of the caffeine content in these beverages. High-end energy drink consumers reported more risk-taking behaviors (increased drug and alcohol use and less frequent seat belt use), sleep disturbances (later bedtimes, harder time falling asleep, and more all-nighters), and higher frequency of mental illness diagnoses than those who consumed fewer energy drinks. In contrast, the frequency of most risk behaviors, sleep disturbances, and mental illness diagnoses was not significantly different between the high-end and general population of coffee drinkers. Conclusion: Students with delayed sleep patterns, mental illness, and higher frequency of substance use and risk behaviors were more likely to be regular energy drink users but not regular coffee drinkers. It is unclear whether the psychoactive content in energy drinks results in different behavioral effects than just caffeine in coffee, and/or different personality/health populations are drawn to the two types of beverages.

Gender-based violence is a well-recognized risk factor for HIV infection among women. Alcohol use is associated with both gender-based violence and sexual risk behavior, but has not been examined as a correlate of both in a context of both high HIV risk and hazardous drinking. The purpose of this paper is to examine the association between recent abuse by a sex partner with alcohol and sexual risk behavior among female patrons of alcohol serving venues in South Africa. Specifically, the aim of this study is to determine whether sexual risk behaviors are associated with gender-based violence after controlling for levels of alcohol use. We surveyed 1,388 women attending informal drinking establishments in Cape Town, South Africa to assess recent history of gender-based violence, drinking, and sexual risk behaviors. Gender-based violence was associated with both drinking and sexual risk behaviors after controlling for demographics among the women. A hierarchical logistic regression analysis showed that after controlling for alcohol use sexual risk behavior remained significantly associated with gender-based violence, particularly with meeting a new sex partner at the bar, recent STI diagnosis, and engaging in transactional sex, but not protected intercourse or number of partners. In South Africa where heavy drinking is prevalent women may be at particular risk of physical abuse from intimate partners as well as higher sexual risk. Interventions that aim to reduce gender-based violence and sexual risk behaviors must directly work to reduce drinking behavior.

Objective Alcohol use is a key determinant of sexual risk behaviors but pathways to alcohol use in the context of commercial sex still remain unclear. The present study explores reasons for drinking and their roles on alcohol use problems among female sex workers (FSWs) in different types of commercial sex venues. Method In 2009, a sample of 1,022 FSWs from Guangxi, China completed a survey containing a 10-item Alcohol Use Disorders Identification Test (AUDIT) and a 28-item measure of reasons for drinking. Factor analysis revealed five reasons for drinking: suppression, disinhibition, work requirement, sexual enhancement, and confidence booster. Results All identified reasons except for confidence booster appeared to be related to a higher tendency of developing alcohol use problems among FSWs. Types of commercial sex venues moderated the relationship between work requirement and alcohol use problems. Conclusions: Alcohol-risk reduction interventions among this population need to provide them with alternative approaches to regulate emotions and modify their misconceptions about alcohol’s sexual enhancing function. More attention is needed to FSWs’ vulnerability to the negative influence of occupational drinking. PMID:25594829

The antiepileptic levetiracetam (LEV) has been investigated for the treatment of alcohol abuse. However, little is known about how LEV alters the behavioral effects of alcohol in laboratory animals. The acute effects of LEV on alcohol drinking by male C57BL/6J mice were investigated using two different drinking procedures, limited access [drinking-in-the-dark (DID)] and intermittent access (IA) drinking. In the first experiment (DID), mice had access to a single bottle containing alcohol or sucrose for 4 h every other day. In the second experiment (IA), mice had IA to two bottles, one containing alcohol or sucrose and one containing water, for 24 h on Monday, Wednesday, and Friday. In both experiments, mice were administered LEV (0.3-100 mg/kg intraperitoneally) or vehicle 30 min before access to the drinking solutions. In the DID mice, LEV increased alcohol intake from 4.3 to 5.4 g/kg, whereas in the IA mice LEV decreased alcohol intake from 4.8 to 3.0 g/kg in the first 4 h of access and decreased 24 h alcohol intake from 20 to ∼15 g/kg. These effects appear specific to alcohol, as LEV did not affect sucrose intake in either experiment. LEV appears to differentially affect drinking in animal models of moderate and heavier alcohol consumption.

Sialadenosis is a unique form of non-inflammatory, non-neoplastic bilateral salivary gland disorder characterized by recurrent painless swelling which usually occurs in parotid glands. Alcoholism is one of the main causes of sialadenosis along with diabetes, bulimia, and other idiopathic causes. The prognosis is verified according to the degree of liver function. We present a case of a 46 year-old man who had alcoholic fatty liver disease diagnosed as alcoholic sialadenosis based on clinical points of recurrent bilateral parotid swelling after heavy alcohol drinking, computed tomography, and fine-needle aspiration biopsy. After stopping alcohol drinking and treated with conservative treatment, he got improved without specific sequela.

The inability to regulate alcohol consumption has been attributed to an imbalance between stimulus-driven behavioral biases, or action tendencies, and the ability to exert goal-directed control, or working memory capacity (WMC). Previous research assessing the interaction between these variables has not considered the effect of whether individuals' current goals or task demands require goal-directed control. Our aim was to examine the potential interaction of appetitive action tendencies and the ability to exert control over these action tendencies as a function of whether task demands require applying control for successful task completion. Two groups of social drinkers (n = 40 per group) who differed in their ability to regulate their alcohol consumption completed a novel variant of the Approach-Avoidance Task (AAT), which separately assessed approach and avoid trials. The approach and avoidance responses differentially require goal-directed control, depending on whether the task-relevant response is incongruent with the stimulus-driven action tendency. Results indicated that (a) group differences in AAT indices were only observed on trials that required an avoidance movement, which are trials where the task-relevant response would be incongruent with an approach action tendency, and (b) the extent of the group differences for these avoidance trials was moderated by individual differences in WMC, such that problem drinkers with lower WMC showed greater behavioral bias toward alcohol than those with higher WMC. These findings suggest that difficulties in regulating alcohol consumption arise from a complex interaction of action-tendencies, WMC, and current goals or task demands.

More than [3/4] of U.S. college students report a heavy drinking episode (HDE; 5 (for men) and 4 (for women) drinks during an occasion) in the previous 90 days. This pattern of drinking is associated with various risks and social problems for both the heavy drinkers and the larger college community. According to behavioral economics, college student drinking is a contextually bound phenomenon that is impacted by contingencies such as price and competing alternative reinforcers, including next-day responsibilities such as college classes. This study systematically examines the role of these variables by using hypothetical alcohol purchase tasks to analyze alcohol consumption and expenditures among college students who reported recent heavy drinking (N = 207, 53.1% women). The impact of gender and the personality risk factor sensation seeking (SS) were also assessed. Students were asked how many drinks they would purchase and consume across 17 drink prices and 3 next-day responsibility scenarios. Mean levels of hypothetical consumption were highly sensitive to both drink price and next-day responsibility, with the lowest drinking levels associated with high drink prices and a next-day test. Men and participants with greater levels of SS reported more demand overall (greater consumption and expenditures) than women and students with low SS personality. Contrary to our hypotheses women appeared to be less sensitive to increases in price than men. The results suggest that increasing drink prices and morning academic requirements may be useful in preventing heavy drinking among college students.

Alcohol use is a known key risk factor associated with risky sexual behavior that contributes to HIV transmission. This cross-sectional study used time location sampling to investigate alcohol use and risky sexual behaviors that occurred after ingesting alcohol among 609 patrons of alcohol venues in Gaborone, Botswana. Alcohol Use Disorders Identification Test (AUDIT) scores were categorized as low (1-7), medium (8-15), and high (16+) for analysis. Logistic regression models stratified by gender assessed the association between alcohol use and condom use at last sex after drinking alcohol. Among females, the odds of condom use during last sex after drinking alcohol were significantly lower for high compared to low AUDIT scores (AOR = 0.17, 95% CI 0.06-0.54). Among males, factors significantly associated with condom use at last sex after alcohol use were low levels of education (primary level compared to university and above AOR = 0.13; 95% CI 0.03-0.55) and beliefs that alcohol use did not increase risky sexual behaviors (AOR = 0.26; 95% CI 0.11-0.62). HIV prevention interventions should target females and emphasize sexual risks associated with alcohol use.

Rationale Previous work has indicated that implicit attentional biases to alcohol-related cues are indicative of susceptibility to alcohol dependence and escape drinking, or drinking to avoid dysphoric mood or emotions. Objective The goal of the current study was to examine whether alcohol dependence and escape drinking were associated with early neural attentional biases to alcohol cues. Methods EEG data were recorded from 54 college students who reported that they regularly drank alcohol, while they viewed alcohol and control pictures that contained human content (active) or no human content (inactive). Results Those who were alcohol dependent showed more neural attentional bias to the active alcohol-related stimuli than to the matched control stimuli early in processing, as indicated by N1 amplitude. Escape drinkers showed greater neural attention to the active alcohol cues than non-escape drinkers, as measured by larger N2 amplitudes. Conclusions While alcohol dependence is associated with enhanced automatic attentional biases early in processing, escape drinking is associated with more controlled attentional biases to active alcohol cues during a relatively later stage in processing. These findings reveal important information about the time-course of attentional processing in problem drinkers and have important implications for addiction models and treatment. PMID:24292342

The process by which peers or the social network influence individual alcohol use, particularly among adults, remains a necessary area of research. The purpose of the present study was to examine the longitudinal influence of “drinking buddies” on alcohol outcomes (i.e., alcohol use, heavy drinking, and alcohol-related problems) as mediated by alcohol expectancies of social facilitation. Participants were 1347 (men = 660) newly married individuals recruited from the community. They were assessed at the time of marriage and through the 4th wedding anniversary. Longitudinal mediation across time was evaluated using latent growth modeling. Overall, the prospective association between the number of drinking buddies in the social network and all three alcohol outcomes were mediated by alcohol expectancies. In testing group invariance across genders, findings suggest that social facilitation expectancies may be more relevant to men as compared to women in predicting typical alcohol use and alcohol-related problems. Given that the social network may impact alcohol use at least in part through social expectancies, tailoring alcohol interventions to modify these specific beliefs may be particularly beneficial. In addition, strategies that target a drinker’s social network or their drinking buddies specifically may be useful. PMID:22732054

Personalized normative feedback is a recommended component of alcohol interventions targeting college students. However, normative data are commonly collected through campus-based surveys, not through actual participant-referent relationships. In the present investigation, we examined how misperceptions of residence hall peers, both overall using a global question and those designated as important peers using person-specific questions, were related to students' personal drinking behaviors. Participants were 108 students (88% freshman, 54% White, 51% female) residing in a single campus residence hall. Participants completed an online baseline survey in which they reported their own alcohol use and perceptions of peer alcohol use using both an individual peer network measure and a global peer perception measure of their residential peers. We employed network autocorrelation models, which account for the inherent correlation between observations, to test hypotheses. Overall, participants accurately perceived the drinking of nominated friends but overestimated the drinking of residential peers. Consistent with hypotheses, overestimating nominated friend and global residential peer drinking predicted higher personal drinking, although perception of nominated peers was a stronger predictor. Interaction analyses showed that the relationship between global misperception and participant self-reported drinking was significant for heavy drinkers, but not non-heavy drinkers. The current findings explicate how student perceptions of peer drinking within an established social network influence drinking behaviors, which may be used to enhance the effectiveness of normative feedback interventions.

Recent studies suggest that the combination of caffeine-containing drinks together with alcohol might reduce the subjective feelings of alcohol intoxication-the so-called "masking effect". In this study, we aimed to review the effects of alcohol in combination with caffeine or energy drink with special focus on the "masking effect". Fifty-two healthy male volunteers were analysed concerning breath alcohol concentration and subjective sensations of intoxication using a 18 item Visual Analogue Scale in a randomised, double-blinded, controlled, four treatments cross-over trial after consumption of (A) placebo, (B) alcohol (vodka 37.5% at a dose of 46.5 g ethanol), (C) alcohol in combination with caffeine at a dose of 80 mg (equivalent to one 250 ml can of energy drink) and (D) alcohol in combination with energy drink at a dose of 250 ml (one can). Primary variables were headache, weakness, salivation and motor coordination. Out of four primary variables, weakness and motor coordination showed a statistically significant difference between alcohol and non-alcohol group, out of 14 secondary variables, five more variables (dizziness, alterations in sight, alterations in walking, agitation and alterations in speech) also showed significant differences due mainly to contrasts with the non-alcohol group. In none of these end points, could a statistically significant effect be found for the additional ingestion of energy drink or caffeine on the subjective feelings of alcohol intoxication. This within-subjects study does not confirm the presence of a "masking effect" when combining caffeine or energy drink with alcohol.

This study examines the associations between alcohol marketing strategies, alcohol education including knowledge about dangers of alcohol and refusal of alcohol, and drinking prevalence, problem drinking, and drunkenness. Analyses are based on the Global School-Based Student Health Survey (GSHS) conducted in Zambia (2004) of students primarily 11 to 16 years of age (N = 2257). Four statistical models were computed to test the associations between alcohol marketing and education and alcohol use, while controlling for possible confounding factors. Alcohol marketing, specifically through providing free alcohol through a company representative, was associated with drunkenness (AOR = 1.49; 95% CI: 1.09-2.02) and problem drinking (AOR = 1.41; 95% CI: 1.06-1.87) among youth after controlling for demographic characteristics, risky behaviors, and alcohol education. However, alcohol education was not associated with drunkenness or problem drinking. These findings underscore the importance of restricting alcohol marketing practices as an important policy strategy for reducing alcohol use and its dire consequences among vulnerable youth.

In a DUI offender sample, four drinking reason factors are regressed on alcohol consumption variables and frequency of drinking in seven types of locations. Drinking for "pleasure" and "opposite sex/drunkenness" reasons are associated with both quantity consumed per occasion and away-from-home locations such as automobiles, bars, and parties, suggesting high traffic accident risk. "Escapism" reasons are related to quantity consumed per occasion, but are only weakly associated with specific locations; and "sociability" reasons are associated with drinking in friends' homes, but are not related to high consumption levels. Implications for DUI countermeasures are discussed.

The effects of alcohol expectancies (AE) and drinking refusal self-efficacy (DRSE) in predicting alcohol consumption in Caucasians has been well studied. However, the role of AE and DRSE in Asian students is still not well understood. This study reported on this using Caucasian (n=98) and Asian (n=92) student samples. Participants completed the Alcohol Use Disorder Identification Test (AUDIT) to measure their hazardous alcohol consumption, and the drinking expectancy profile (DEP) to assess their alcohol related expectancies and ability to resist drinking in certain situations. Results showed that Caucasians reported significantly higher confidence, higher sexual interest, and higher tension reduction expectancies than Asians. Conversely, Asians significantly expected cognitive enhancement and negative consequences more than Caucasians. Relative to Caucasians, the Asian sample also reported that they would be more able to refuse alcohol when under social pressure. Results from regression analyses showed that for the Caucasian sample, AE, DRSE and their interactions were significant predictors of alcohol consumption. For the Asian group, the only significant effect to emerge was that DRSE was negatively related to alcohol consumption. The clinical implications of the differential pattern of results between the samples are discussed in terms of self-efficacy and negative consequences of alcohol consumption, especially when dealing with university aged individuals.

Alcoholism and alcohol use disorders are characterized by several months to decades of heavy and problematic drinking, interspersed with periods of abstinence and relapse to heavy drinking. This alcohol-drinking phenotype was modeled using macaque monkeys to explore neuronal adaptations in the striatum, a brain region controlling habitual behaviors. Prolonged drinking with repeated abstinence narrowed the variability in daily intake, increased the amount of ethanol consumed in bouts, and led to higher blood ethanol concentrations more than twice the legal intoxication limit. After the final abstinence period of this extensive drinking protocol, we found a selective increase in dendritic spine density and enhanced glutamatergic transmission in the putamen, but not in the caudate nucleus. Intrinsic excitability of medium-sized spiny neurons was also enhanced in the putamen of alcohol-drinking monkeys in comparison with non-drinkers, and GABAeric transmission was selectively suppressed in the putamen of heavy drinkers. These morphological and physiological changes indicate a shift in the balance of inhibitory/excitatory transmission that biases the circuit toward an enduring increase in synaptic activation of putamen output as a consequence of prolonged heavy drinking/relapse. The resultant potential for increased putamen activation may underlie an alcohol-drinking phenotype of regulated drinking and sustained intoxication.

Individuals with elevated social anxiety appear particularly vulnerable to experiencing alcohol-related problems; yet we know little about factors that may account for this relationship. One possibility is that socially anxious individuals hold beliefs about the impressions they make on others while drinking and these beliefs play an important role in their drinking behaviors. The present study used exploratory factor analysis among participants with clinically elevated social anxiety (n=166) to develop a measure, the Social Impressions while Drinking Scale (SIDS), to assess beliefs regarding others' impressions of drinking behaviors that may be particularly relevant to socially anxious individuals. A valuations scale was also developed to assess the importance of each belief. Empirically-derived subscales were identified with adequate reliability. Among socially anxious participants, the Gregarious and Sexual Facilitation subscales were uniquely related to drinking problems and frequency respectively. Individuals with clinically meaningful social anxiety achieved higher scores on all SIDS subscales compared to those with lower social anxiety (n=166). Several SIDS scales mediated the relations between social anxiety group status and drinking problems (Interaction Fears, Observation Fears, Aggression, Gregariousness). Results highlight the importance of examining beliefs specific to high-risk populations in assessing their alcohol-related behaviors.

Since the 1990s, we have suggested the concept of pre-alcoholism which encompasses patients who have drunk a great deal of alcohol leading to alcohol related problems such as health issues, domestic violence, drunken driving and black-outs. Pre-alcoholism excludes alcohol-dependent patients who have experienced continuous drinking or withdrawal symptoms. We have treated many outpatients with pre-alcoholism for several years. Our regimen demands that the patients must be abstinent for half a year at the beginning of their treatment. After half a year they can choose whether they will continue to be abstinent or they will resume drinking with the aim of reducing their total alcohol consumption. The study clarified the character of pre-alcoholism by investigation of the patients' background and re-diagnosis of the patients based on the International Classification of Diseases, 10th Revision (ICD-10). A remarkable ratio of pre-alcoholic patients was diagnosed with alcohol dependence under ICD-10. We classified pre-alcoholic patients into two groups, one diagnosed as having ICD-10-classed alcohol dependence and the other which did not fulfill the ICD-10 diagnostic criteria of alcohol dependence, and examined the therapeutic processes of the two groups. It was shown that most pre-alcoholic patients could finally take required courses of treatment by themselves without regard to diagnosis under ICD-10, even if they chose any treatment and made alcohol related mistakes on the way. Our findings suggested that pre-alcoholic patients, a portion of whom may have exhibited mild alcohol dependence, could select drinking reduction as a primary goal of treatment after a certain period of abstinence.

This study builds on research identifying deficits in behavioral self-regulation as risk factors for intimate partner violence (IPV). It also builds on alcohol administration research identifying these deficits as moderators of the association between acute alcohol consumption and aggression in laboratory paradigms. Participants analyzed were 97 men seeking residential treatment for alcohol dependence who were involved in a current or recent heterosexual relationship of at least 1 year. Participants completed a self-report measure of impulsivity, neuropsychological tests of executive function, and computerized delay discounting and behavioral inhibition tasks. With the exception of the self-report measure of impulsivity, performance on measures of behavioral self-regulation was not associated with the occurrence or frequency of past year IPV in this sample. Similarly, self-reported impulsivity moderated the association between daily drinking and IPV in multivariate models controlling for daily drug use, but deficits in performance on other measures did not. Performance on a tower task moderated the association between daily drinking and the occurrence of IPV, but contrary to hypotheses, better task performance was associated with greater likelihood of IPV on drinking days. These results suggest that self-perceived impulsivity is a better predictor of IPV in alcohol treatment seeking men than deficits in performance on behavioral measures of delay discounting, behavioral inhibition, and executive function.

Background: The quantitative, measurable detection of drinking is important for the successful treatment of alcohol misuse in transplantation of patients with alcohol disorders, people living with human immunodeficiency virus that need to adhere to medication, and special occupational hazard offenders, many of whom continually deny drinking. Their initial misconduct usually leads to medical problems associated with drinking, impulsive social behavior, and drunk driving. The accurate identification of alcohol consumption via biochemical tests contributes significantly to the monitoring of drinking behavior. Methods: A systematic review of the current methods used to measure biomarkers of alcohol consumption was conducted using PubMed and Google Scholar databases (2010–2015). The names of the tests have been identified. The methods and publications that correlate between the social instruments and the biochemical tests were further investigated. There is a clear need for assays standardization to ensure the use of these biochemical tests as routine biomarkers. Findings: Alcohol ingestion can be measured using a breath test. Because alcohol is rapidly eliminated from the circulation, the time for detection by this analysis is in the range of hours. Alcohol consumption can alternatively be detected by direct measurement of ethanol concentration in blood or urine. Several markers have been proposed to extend the interval and sensitivities of detection, including ethyl glucuronide and ethyl sulfate in urine, phosphatidylethanol in blood, and ethyl glucuronide and fatty acid ethyl esters in hair, among others. Moreover, there is a need to correlate the indirect biomarker carbohydrate deficient transferrin, which reflects longer lasting consumption of higher amounts of alcohol, with serum γ-glutamyl transpeptidase, another long term indirect biomarker that is routinely used and standardized in laboratory medicine.

Social norms affect human behavior, and underage drinking is no exception. Using the theory of normative social behavior, this study tested the proposition that the association between perceptions about the prevalence of drinking (descriptive norms) and underage drinking is strengthened when perceived pressures to conform (injunctive norms) and beliefs about the benefits of drinking (outcome expectations) are high. This proposition was tested on a nationally representative sample of underage drinkers ages 13-20 (N = 1,031) in relation to their alcohol consumption, expanding on research with college-age youth. On average, males and females reported drinking 23 and 18 drinks per month, respectively. The main effect of descriptive norms (β = .10, p < .01) on alcohol consumption was modified by interactions with injunctive norms (β = .11, p < .01), benefit to self (β = .12, p < .001), and benefit to others (β = .10, p < .01). Underage drinkers are most vulnerable to excessive drinking if they believe that most others drink, that they themselves are expected to drink, and that drinking confers several benefits. Norms-based interventions to reduce youth alcohol use need to focus on changing not only descriptive norms but also injunctive norms and outcome expectations.

This longitudinal study of 1,447 first-time college students tested separate time-varying covariate models of the relations between academic and social motives/behaviors and alcohol use and related problems from senior year of high school through the end of the second year in college. Structural equation models identified small but significant inverse relations between academic motives/behaviors and alcohol use across all time points, with relations of somewhat larger magnitude between academic motives/behaviors and alcohol-related problems across all semesters other than senior year in high school. At all time points, there were much larger positive relations between social motives/behaviors and alcohol use across all semesters, with smaller but significant relations between social motives/behaviors and alcohol-related problems. Multi-group models found considerable consistency in the relations between motives/behaviors and alcohol-related outcomes across gender, race/ethnicity, and family history of alcohol problems, although academic motives/behaviors played a stronger protective role for women, and social motives were a more robust risk factor for Caucasian and Latino students and individuals with a positive family history of alcohol problems. Implications for alcohol prevention efforts among college students are discussed.

Excessive alcohol use is a serious public health concern worldwide, but less attention has been given to the prevalence, risk and protective factors, and consequences of early alcohol use in low-income, developing countries. The purpose of this study was to determine the associations between early alcohol use, before age 13, and problem drinking among adolescents in Uganda and Zambia. Data from students in Zambia (n=2257; 2004) and Uganda (n=3215; 2003) were obtained from the cross-sectional Global School-Based Student Health Survey (GSHS). The self-administered questionnaires were completed by students primarily 13 to 16 years of age. Multiple statistical models were computed using logistic regression analyses to test the associations between early alcohol initiation and problem drinking, while controlling for possible confounding factors (e.g., current alcohol use, bullying victimization, sadness, lack of friends, missing school, lack of parental monitoring, and drug use). Results show that early alcohol initiation was associated with problem drinking in both Zambia (AOR=1.28; 95% CI:1.02–1.61) and Uganda (AOR=1.48; 95% CI: 1.11–1.98) among youth after controlling for demographic characteristics, risky behaviors, and other possible confounders.The study shows that there is a significant association between alcohol initiation before 13 years of age and problem drinking among youth in these two countries. These findings underscore the need for interventions and strict alcohol controls as an important policy strategy for reducing alcohol use and its dire consequences among vulnerable youth.

Purpose To investigate the temporal relation between energy drink and alcohol use among adolescents. Methods Data were collected from adolescents attending public high schools in two waves (n = 894). Results Path analysis indicated that energy drink use at baseline was positively associated with the number of drinking days but not binge drinking or average drinks per drinking day over the past 30 days at follow-up. This relation remained while controlling for race, age, gender, previous alcohol use, and impulsivity. Conclusions Alcohol use prevention efforts should consider energy drink use as risk factors for adolescent alcohol use. PMID:26632245

Social factors have a tremendous influence on instances of heavy drinking and in turn impact public health. However, it is extremely difficult to assess whether this influence is only a cultural phenomenon or has biological underpinnings. Research in non-human primates demonstrates that the way individuals are brought up during early development affects their future predisposition for heavy drinking, and research in rats demonstrates that social isolation, crowding or low social ranking can lead to increased alcohol intake, while social defeat can decrease drinking. Neurotransmitter mechanisms contributing to these effects (i.e., serotonin, GABA, dopamine) have begun to be elucidated. However, these studies do not exclude the possibility that social effects on drinking occur through generalized stress responses to negative social environments. Alcohol intake can also be elevated in positive social situations, for example, in rats following an interaction with an intoxicated peer. Recent studies have also begun to adapt a new rodent species, the prairie vole, to study the role of social environment in alcohol drinking. Prairie voles demonstrate a high degree of social affiliation between individuals, and many of the neurochemical mechanisms involved in regulation of these social behaviors (for example, dopamine, central vasopressin and the corticotropin releasing factor system) are also known to be involved in regulation of alcohol intake. Naltrexone, an opioid receptor antagonist approved as a pharmacotherapy for alcoholic patients, has recently been shown to decrease both partner preference and alcohol preference in voles. These findings strongly suggest that mechanisms by which social factors influence drinking have biological roots, and can be studied using rapidly developing new animal models.

Problem drinking during the college years continues to be an important area of study. Subjective evaluations of consequences have recently been demonstrated to predict future drinking behavior; however, what predicts those evaluations is yet unknown. Social Learning Theory (SLT) provides a guiding framework in this study with primary aims to investigate whether individual differences in past experience with and normative perceptions of alcohol consequences predict subjective evaluations (i.e., the extent to which consequences are perceived as negative, aversive, or severe) and weekly drinking behavior. We also test whether evaluations mediate the influence of past consequences and norms on weekly drinking behavior. Following a baseline assessment, participants (N=96 regularly drinking college students, 52% female) completed ten weekly web-based surveys on previous week alcohol use, consequences, and subjective evaluations of those consequences. A series of hierarchical linear models were used to test hypotheses. Most mediational pathways were not supported – weekly level evaluations do not appear to fully explain the effect of norms or past experience on weekly level drinking behavior. However, results demonstrated that normative perceptions of and past experience with consequences were associated with both weekly drinking behavior and subjective evaluations, and evaluations remained significant predictors of alcohol use behavior after accounting for these important between-person influences. Findings support the importance placed by SLT on cognition in drinking behavior, and suggest that norms for consequences and subjective evaluations may be appropriate targets of intervention in college students.

Lesbian, gay, and bisexual young adults are at elevated risk for drinking compared to heterosexual young adults, and this discrepancy is particularly striking for sexual minority women (SMW). Perceived social norms are strong predictors of young adult alcohol use, especially among college students. The college environment is often one where increases in alcohol use are seen, but the impact of college status on SMW's drinking has been understudied. The present study explored patterns of alcohol use and consequences among SMW and the extent to which social norms relate to use and consequences. Participants were recruited via social networking sites for a larger national study on SMW's health behaviors. Present analyses focused on 875 SMW between 18 and 25 who were categorized as either a 2-year college student (n = 196), 4-year college student (n = 418), or non-student (n = 261). Several differences emerged between college and non-college SMW, with non-college women reporting higher alcohol use and social norms compared to 4-year college women. In terms of alcohol-related consequences, students in both 2-year and 4-year colleges reported a higher likelihood of any consequences. There was some evidence that perceived norms partially explained differences in typical drinking among the college status groups. The present findings suggest that college may play a protective role against heavy drinking for this population of young women, however, the results are not straightforward and additional research is warranted.

This study examined concurrent and prospective associations of financial stress (financial strain, lack of financial access, public assistance) and parenting support factors (relationship quality, living at home, financial support) with young adults’ alcohol behaviors (alcohol use, heavy drinking, and problematic drinking) over a 5-year period. Analyses of National Longitudinal Study of Adolescent Health (Add Health) data (N = 7,159) showed that, over the study period, alcohol use and heavy drinking declined while problematic drinking increased. In addition, living at home and parental relationship quality were associated with fewer concurrent and prospective alcohol behaviors whereas financial strain and parents’ financial support were associated with more alcohol behaviors. The implications for minimizing alcohol misuse in young adults amid uncertain economic conditions are discussed. PMID:26388681

Drinking alcohol clearly has important effect on social behaviors, such as increasing aggression, self-disclosure, sexual adventuresomeness, and so on. Research has shown that these effects can stem from beliefs we hold about alcohol effects. Less is known about how alcohol itself affects these behaviors. A cognitive explanation, that alcohol impairs the information processing needed to inhibit response impulses--the abilities to foresee negative consequences of the response, to recall inhibiting standards, and so on--has begun to emerge. We hypothesize that alcohol impairment will make a social response more extreme or excessive when the response is pressured by both inhibiting and instigating cues--in our terms, when it is under inhibitory response conflict. In that case, alcohol's damage to inhibitory processing allows instigating pressures more sway over the response, increasing its extremeness. In the present meta-analysis, each published test of alcohol's effect on a social, or socially significant behavior was rated (validated against independent judges) as to whether it was under high or low inhibitory conflict. Over low-conflict tests, intoxicated subjects behaved only a tenth of a standard deviation more extremely than their sober controls, whereas over high-conflict tests they were a full standard deviation more extreme. The effect of conflict increased with alcohol dosage, was shown not to be mediated by drinking expectancies, and generalized with few exceptions across the 34 studies and 12 social behaviors included in this analysis.

To decrease the prevalence and the amount of alcohol consumption among students, health messages advocating responsible alcohol behavior can be used. However, it is unclear whether responsible drinking messages are most effective when they use a gain frame, presenting the advantages of responsible drinking, or a loss frame, presenting the disadvantages of irresponsible drinking. This study tests the effects of framing and the moderating role of involvement with the issue of responsible drinking. A three-wave, between-subjects, experimental study was conducted, in which participants (N = 90) were exposed to either a gain- or loss-framed message about responsible drinking behavior at Wave 2. At all three waves, attitudes, intentions and behavior toward responsible drinking were measured. Results showed that for participants with low issue- involvement, a gain frame led to more positive attitudes and intentions toward responsible alcohol use, whereas a loss frame did not have any effects for them. For participants with high issue involvement, a loss frame led to more positive attitudes and intentions toward responsible alcohol use, whereas a gain frame did not have an effect on attitude and only a delayed effect on intention. However, there were no effects of frame and issue involvement on adhering to the guideline of responsible alcohol use and average drinking behavior.

The rationale for our study was to determine the pattern of ethanol drinking by the high alcohol-drinking (HAD) replicate lines of rats during adolescence and adulthood in both male and female rats. Rats were given 30 days of 24 h free-choice access to ethanol (15%, v/v) and water, with ad lib access to food, starting at the beginning of adolescence (PND 30) or adulthood (PND 90). Water and alcohol drinking patterns were monitored 22 h/day with a "lickometer" set-up. The results indicated that adolescent HAD-1 and HAD-2 males consumed the greatest levels of ethanol and had the most well defined ethanol licking binges among the age and sex groups with increasing levels of ethanol consumption throughout adolescence. In addition, following the first week of adolescence, male and female HAD-1 and HAD-2 rats differed in both ethanol consumption levels and ethanol licking behavior. Adult HAD-1 male and female rats did not differ from one another and their ethanol intake or licking behaviors did not change significantly over weeks. Adult HAD-2 male rats maintained a relatively constant level of ethanol consumption across weeks, whereas adult HAD-2 female rats increased ethanol consumption levels over weeks, peaking during the third week when they consumed more than their adult male counterparts. The results indicate that the HAD rat lines could be used as an effective animal model to examine the development of ethanol consumption and binge drinking in adolescent male and female rats providing information on the long-range consequences of adolescent alcohol drinking.

High-intensity drinking (i.e., women/men consuming 8+/10+ drinks in a day) is prevalent and associated with negative consequences. Occasions of high-intensity drinking have markedly high risk; however, previous research has not examined the predictors of these high-risk drinking days. The current study was designed to examine to what extent positive and negative alcohol expectancies predict high-intensity drinking and whether high-intensity drinking on a given day was associated with drinking consequences and their evaluations that day. Frequently drinking college students (N=342) participated in an intensive longitudinal study of drinking behaviors (N=4645 drinking days). Days with greater positive and negative expectancies were associated with high-intensity drinking. Days with high-intensity drinking were associated with reporting more positive and negative consequences and with evaluating positive consequences more favorably and evaluating negative consequences less favorably, compared to drinking days without high-intensity drinking. Given this, prevention and intervention efforts may consider specifically targeting high-intensity drinking events as a unique phenomenon.

Addiction to alcohol remains a major social and economic problem, in part because of the high motivation for alcohol that humans exhibit and the hazardous binge intake this promotes. Orexin-1-type receptors (OX1Rs) promote reward intake under conditions of strong drives for reward, including excessive alcohol intake. While systemic modulation of OX1Rs can alter alcohol drinking, the brain regions that mediate this OX1R enhancement of excessive drinking remain unknown. Given the importance of the nucleus accumbens (NAc) and anterior insular cortex (aINS) in driving many addictive behaviors, including OX1Rs within these regions, we examined the importance of OX1Rs in these regions on excessive alcohol drinking in C57BL/6 mice during limited-access alcohol drinking in the dark cycle. Inhibition of OX1Rs with the widely used SB-334867 within the medial NAc Shell (mNAsh) significantly reduced drinking of alcohol, with no effect on saccharin intake, and no effect on alcohol consumption when infused above the mNAsh. In contrast, intra-mNAsh infusion of the orexin-2 receptor TCS-OX2-29 had no impact on alcohol drinking. In addition, OX1R inhibition within the aINS had no effect on excessive drinking, which was surprising given the importance of aINS-NAc circuits in promoting alcohol consumption and the role for aINS OX1Rs in driving nicotine intake. However, OX1R inhibition within the mPFC did reduce alcohol drinking, indicating cortical OXR involvement in promoting intake. Also, in support of the critical role for mNAsh OX1Rs, SB within the mNAsh also significantly reduced operant alcohol self-administration in rats. Finally, orexin ex vivo enhanced firing in mNAsh neurons from alcohol-drinking mice, with no effect on evoked EPSCs or input resistance; a similar orexin increase in firing without a change in input resistance was observed in alcohol-naïve mice. Taken together, our results suggest that OX1Rs within the mNAsh and mPFC, but not the aINS, play a central role in

Many pregnant women drink varying quantities of alcohol, although several guidelines recommend total abstinence. What is known of the dangers of alcohol for the outcome of pregnancy and for the unborn child? To answer this question, we conducted a review of the literature using the standard Prescrire methodology. Fetal alcohol syndrome, which combines facial dysmorphism, growth retardation and intellectual disability, occurs in about 5% of children who are regularly exposed to at least five standard units per day (about 50 g of alcohol per day). Four studies have explored the link between heavy maternal alcohol use over a short period and the risk of cognitive impairment in the child. The results were inconclusive, however, and the authors failed to take concomitant chronic alcohol consumption into account. A methodologically sound study showed an increase in neurological abnormalities (seizures and epilepsy) when the mother drank heavily during short periods between the 11th and 16th weeks of pregnancy. There is a risk of cognitive and behavioural problems in children whose mothers regularly drank more than 2 standard units per day. Studies involving a total of about 150 000 pregnancies sought a link between low-level alcohol consumption and abnormal pregnancy outcomes. Very few showed a statistically significant link, and the results are undermined by the failure to take other risk factors into account. Weekly consumption of 5 standard units or more during pregnancy has been linked to an increased risk of cryptorchidism. Studies in a total of 57 000 pregnancies showed no effect of minimal alcohol consumption on the risk of malformations. A study of 1000 pregnancies showed a statistically significant risk of major malformations, but there were several apparent biases. A link between infant mortality and alcohol consumption during pregnancy was examined in large cohort studies. Consumption of at least 4 standard units per week increased the risk of early neonatal

Since the advent of energy drinks in the U.S. marketplace, some defendants have claimed that positive breath alcohol test results have occurred due to the ingestion of non-alcoholic energy drinks. A variety of energy drinks were tested by gas chromatography and some 88.9% (24 of 27) were found to contain low concentrations of ethanol (5-230 mg/dL). Drinks were then consumed (24.6-32 oz) by volunteers to determine the extent of reaction that could be achieved on a portable breath-testing instrument. Eleven of 27 (40.7%) beverages gave positive results on a portable breath-testing instrument (0.006-0.015 g/210 L) when samples were taken within 1 min of the end of drinking. All tests taken by portable breath test, DataMaster, and Intox EC/IR II at least 15 min after the end of drinking resulted in alcohol-free readings (0.000 g/210 L). Affording subjects a minimum 15-min observation period prior to breath-alcohol testing eliminates the possibility that a small false-positive alcohol reading will be obtained.

People are exposed to many references to alcohol, which might influence their consumption of alcohol directly. In a field experiment, we tested whether textual references to alcohol in music played in bars lead to higher revenues of alcoholic beverages. We created two databases: one contained songs referring to alcohol, the parallel database contained songs with matching artists, tempo, and energetic content, but no references to alcohol. Customers of three bars were exposed to either music textually referring to alcohol or to the control condition, resulting in 23 evenings in both conditions. Bartenders were instructed to play songs with references to alcohol (or not) during a period of 2 hours each of the evenings of interest. They were not blind to the experimental condition. The results showed that customers who were exposed to music with textual references to alcohol spent significantly more on alcoholic drinks compared to customers in the control condition. This pilot study provides preliminary evidence that alcohol-related lyrics directly affect alcohol consumption in public drinking places. Since our study is one of the first testing direct effects of music lyrics on consumption, our small-scale, preliminary study needs replication before firm conclusions can be drawn.

Stress and impulsivity contribute to alcohol use, and stress may also act via impulsivity to increase drinking behavior. Impulsivity represents a multi-faceted construct and self-report and behavioral assessments may effectively capture distinct clinically relevant factors. The present research investigated whether aspects of impulsivity mediate the effect of stress on alcohol use. A community-based sample of 192 men and women was assessed on measures of cumulative stress, alcohol use, self-reported impulsivity, and behavioral choice and response impulsivity. Data were analyzed using regression and bootstrapping techniques to estimate indirect effects of stress on drinking via impulsivity. Cumulative adversity exhibited both direct effects and indirect effects (via self-reported impulsivity) on drinking behavior. Additional models examining specific types of stress indicated direct and indirect effects of trauma and recent life events, and indirect effects of major life events and chronic stressors on drinking behavior. Overall, cumulative stress was associated with increased drinking behavior, and this effect was partially mediated by self-reported impulsivity. Self-reported impulsivity also mediated the effects of different types of stress on drinking behavior. These findings highlight the value of mediation models to examine the pathways through which different types of stress increase drinking behavior. Treatment and prevention strategies should focus on enhancing stress management and self-control.

Objective: Although college students experience a diverse range of alcohol consequences, most studies focus on global, rather than distinct, consequence types. One predictor of unique consequences—drinking motives—has been studied only cross-sectionally. We aimed to examine the prediction of unique alcohol consequence domains (social/interpersonal, academic/occupational, risky behavior, impaired control, poor self-care, diminished self-perception, blackout drinking, and physiological dependence) by coping and enhancement motives over the course of one year. We hypothesized that coping motives would directly predict and that enhancement motives would indirectly (through alcohol use) predict unique consequences. Method: Web surveys were administered to a sample of college students (n = 552, 62% female) at the beginning of the fall semester for 2 consecutive academic years. Structural equation modeling was used to test direct and indirect paths from motives to consequences. Results: The data supported hypothesized direct, prospective paths from coping motives to several alcohol consequences (impaired control, diminished self-perception, poor self-care, risky behaviors, academic/occupational, and physiological dependence). These associations were not mediated by alcohol consumption. Enhancement motives were indirectly associated with all eight consequence domains by way of increased alcohol use at follow-up. Models were invariant across gender, year in school, and symptoms of posttraumatic stress. Conclusions: Findings suggest that whether motives act as a final common pathway to problem drinking may depend on which motives and which drinking outcomes are examined. As coping motives demonstrate a direct link to unique alcohol problem types over time, individuals endorsing these motives may need to be prioritized for intervention. PMID:24411801
Background This study evaluated a decisional balance intervention among heavy drinking undergraduates and compared a non-weighted decisional balance proportion (DBP; Collins, Carey, & Otto, 2009) to a participant-weighted DBP with weights based on relative importance of items. We expected: 1) the intervention to decrease drinking compared to control; 2) the weighted intervention to be more effective compared to the non-weighted or control in reducing drinking; and 3) intervention efficacy to be moderated by initial DBP. Method Participants (N =162, Mean age = 24.37, SD = 6.81, 27% male) were randomly assigned to an alcohol intervention wherein they were either asked to assign weights of importance to pros and cons (weighted intervention), or not (non-weighted intervention), or to control. Participants completed web-based questionnaires at baseline and again during a one month follow-up assessment. Results Consistent with expectations, the non-weighted intervention was associated with reduced follow-up weekly drinking, and the weighted intervention was associated with reductions in drinking frequency. Results further indicated that initial decisional balance did not moderate intervention efficacy. Discussion Findings suggest that the decisional balance procedure can reduce drinking but there was not compelling evidence for the addition of weights. This study lays the groundwork for enhancing future interventions by increasing empirical knowledge of the role motivation plays in heavy alcohol use. PMID:26555004

Oxygen plays an important role in the metabolism of alcohol. An increased dissolved oxygen level in alcoholic beverages reportedly accelerates the elimination of alcohol. Therefore, we evaluated the effect of dissolved oxygen in alcohol and the supportive effect of oxygenated water on alcohol pharmacokinetics after the excessive consumption of alcohol, i.e., 540 ml of 19.5% alcohol (v/v). Fifteen healthy males were included in this randomized, 3 × 3 crossover study. Three combinations were tested: X, normal alcoholic beverage and normal water; Y, oxygenated alcoholic beverage and normal water; Z, oxygenated alcoholic beverage and oxygenated water. Blood alcohol concentrations (BACs) were determined by conversion of breath alcohol concentrations. Four pharmacokinetic parameters (C(max), T(max), K(el), and AUCall) were obtained using non-compartmental analysis and the times to reach 0.05% and 0.03% BAC (T(0.05%) and T(0.03%)) were compared using one-way analysis of variance (ANOVA) and Duncan's post hoc test. With combination Z, the BAC decreased to 0.05% significantly faster (p < 0.05) than with combination X. Analyzing the pharmacokinetic parameters, the mean K(el) was significantly higher for combination Z than for combinations X and Y (p < 0.05), whereas the mean values of C(max), T(max) and AUCall did not differ significantly among the combinations. Dissolved oxygen in drinks accelerates the decrease in BAC after consuming a large amount of alcohol. However, the oxygen dissolved in the alcoholic beverage alone did not have a sufficient effect in this case. We postulate that highly oxygenated water augments the effect of oxygen in the alcoholic beverage in alcohol elimination. Therefore, it is necessary to investigate the supportive effect of ingesting additional oxygenated water after heavy drinking of normal alcoholic beverages.

Objective To examine characteristics of alcohol mixed with energy drink (AmED) use in a sample of college students. Participants College students (N=614, 53% female) in their second year of college participated during the fall of 2008. Method Students completed a cross-sectional survey with questions regarding AmED use. Results AmED use in the last 30 days was reported by 27% of participants. Logistic regression analyses found that risk factors for AmED included participating in a fraternity/sorority; participating in athletics; living off-campus; having greater fun/social, relax, image motives for alcohol consumption; and binge drinking. Protective factors included early morning classes, Honors Program participation, and greater physical/behavioral motives for not drinking. Conclusions Risk factors for AmED use can identify college students most likely to consume AmEDs and thereby inform screening and intervention efforts to reduce negative AmED-related consequences.

Study abroad programs have the potential to promote cultural, experiential, and personal development for escalating numbers of American college students each year. Despite reports that study abroad students may be at particular risk for increased and problematic alcohol use, there is limited empirical documentation of this risk. Thus, the present study used a longitudinal design to examine the factors associated with changes in alcohol use among college students studying in foreign countries. A sample of 177 students completed measures of demographics, drinking behavior, and perceived peer drinking behavior one month prior to departure and one-month post-study abroad return. Analyses revealed that participants more than doubled their drinking during study abroad trips and those who drank at heavier levels while abroad returned home drinking at significantly elevated levels. This pattern of increased use while abroad was moderated by several factors, with participants studying abroad in Europe (e.g., Italy, France) and Oceania (e.g., Australia, New Zealand), those under the age of 21, those with higher intentions of drinking while abroad, and those with higher drinking perceptions of other study abroad students in their host country increased their alcohol consumption to a greater extent than other participants. Results suggest drinking while abroad is a concern warranting further investigation, especially regarding how changes in drinking may contribute to the experience of alcohol-related consequences abroad. Continued identification of the risk factors associated with increased drinking can help inform targeted pre-departure preventive interventions with these students. PMID:20853940

This study examined whether the relationship between friends' drinking norms and male adolescents' alcohol use is moderated by performance-based peer influence susceptibility. Seventy-three male adolescents (M = 17 years) from three schools in the Netherlands were exposed to the drinking norms of "peers" (electronic confederates) in a chat room experiment. These peers were either popular or unpopular, and conveyed pro- or anti-alcohol norms. Peer influence susceptibility was defined as the change in adolescents' answers before and after exposure to the peer norms. Multilevel regression analyses indicated that the relationship between friends' drinking norms and adolescents' alcohol use (assessed during eight weekends) was moderated by susceptibility to the pro-alcohol norms of popular peers. This relationship was stronger for adolescents who were highly susceptible. These findings suggest that a behavioral measure of peer influence susceptibility could be useful in alcohol prevention programs to select adolescents at risk for negative peer socialization.

The anxiolytic effects of neuropeptide Y (NPY) are mediated in part by the central nucleus of the amygdala (CeA), a brain region involved in the regulation of alcohol-drinking behaviors. Centrally administered NPY suppresses alcohol drinking in subpopulations of rats vulnerable to the development of high alcohol-drinking behavior. The purpose of the current study was to determine the role of NPY in the CeA on elevated alcohol drinking produced by alcohol dependence. Adult male Wistar rats were trained to respond for 10% w/v alcohol in an operant situation with the use of a supersaccharin fading procedure. Following stabilization of responding, rats were divided into two groups matched for intake and given daily access to either alcohol-containing (9.2% v/v) liquid diet or an isocaloric control diet. Following extended access to the diet and reliable separation of operant responding between dependent and non-dependent rats during 6-h withdrawal tests, all rats were implanted bilaterally with cannulae aimed at the CeA. Rats were then infused with 4 NPY doses (0.0, 0.25, 0.5, 1.0 microg/0.5 microl aCSF) in a within-subjects Latin-square design during acute withdrawal and tested for operant alcohol responding 30 min later. Alcohol-dependent rats exhibited higher operant alcohol responding than non-dependent rats when infused with vehicle, but responding was similar in the two groups following infusion of all doses of NPY. These results indicate that NPY abolishes dependence-induced elevations in alcohol drinking and implicate the recruitment of limbic NPY systems in the motivational drive to consume alcohol following the transition to dependence.

This study examined the joint effects of contextual cues and alcohol intoxication on the associations between activation of positive and negative alcohol expectancies in memory and self-reported urges to drink alcohol after a laboratory alcohol administration. Young adult heavy drinkers were randomly assigned to drink a moderate dose of alcohol or a placebo (alcohol manipulation), and then listened to positive or negative drinking scenarios (cue manipulation). Before and after these manipulations, participants completed an alcohol expectancy Stroop task assessing positive and negative expectancy activation, as well as self-report measures of urges to drink. Regression analyses revealed that the alcohol and cue manipulations had a joint, moderating impact on the associations between expectancy activation and postcue changes in urge to drink. Specifically, both increased activation of negative expectancies and decreased activation of positive expectancies predicted decreases in urges to drink, but only for intoxicated participants in the negative cue condition. There were no associations between expectancy activation and urges to drink for those in the positive cue condition regardless of beverage condition. Results suggest that whether memory activation of alcohol expectancies has an impact on urge to drink after alcohol is on board may depend on the relevance of the activated expectancies to the current drinking context. This process appears to be influenced by a complex interaction between contextual cues in the environment and the pharmacological effects of alcohol.

Background Participation in drinking games is associated with excessive drinking and alcohol risks. Despite the growing literature documenting the ubiquity and consequences of drinking games, limited research has examined the influence of psychosocial factors on the experience of negative consequences as the result of drinking game participation. Objectives The current event-level study examined the relationships among drinking game participation, social anxiety, drinking refusal self-efficacy (DRSE) and alcohol-related consequences in a sample of college students. Methods Participants (n =976) reported on their most recent drinking occasion in the past month in which they did not preparty. Results After controlling for sex, age, and typical drinking, higher levels of social anxiety, lower levels of DRSE, and playing drinking games predicted greater alcohol-related consequences. Moreover, two-way interactions (Social Anxiety × Drinking Games, DRSE × Drinking Games) demonstrated that social anxiety and DRSE each moderated the relationship between drinking game participation and alcohol-related consequences. Participation in drinking games resulted in more alcohol problems for students with high social anxiety, but not low social anxiety. Students with low DRSE experienced high levels of consequences regardless of whether they participated in drinking games; however, drinking game participation was associated with more consequences for students confident in their ability to resist drinking. Conclusion Findings highlight the important role that social anxiety and DRSE play in drinking game-related risk, and hence provide valuable implications for screening at-risk students and designing targeted harm reduction interventions that address social anxiety and drink refusal in the context of drinking games.

Background College students who engage in high-risk drinking patterns are thought to “mature out” of these patterns as they transition to adult roles. College graduation is an important milestone demarcating this transition. We examine longitudinal changes in quantity and frequency of alcohol consumption between the college years and the four years after graduation; and explore variation in these changes by gender and race/ethnicity. Methods Participants were 1128 college graduates enrolled in a longitudinal prospective study of health-risk behaviors. Standard measures of alcohol consumption were gathered during eight annual personal interviews (76% to 91% annual follow-up). Graduation dates were culled from administrative data and self-report. Spline models, in which separate trajectories were modeled before and after the “knot” of college graduation, were fit to eight annual observations of past-year alcohol use frequency and quantity (typical number of drinks/drinking day). Results Frequency increased linearly pre-graduation, slightly decreased post-graduation, and then rebounded to pre-graduation levels. Pre-graduation frequency increased more steeply among individuals who drank more heavily at college entry. Quantity decreased linearly during college, followed by quadratic decreases after graduation. Conclusions Results suggest that the post-college “maturing out” phenomenon might be attributable to decreases in alcohol quantity but not frequency. High-frequency drinking patterns that develop during college appear to persist several years post-graduation. PMID:26893253
Heavy drinking contributes to involuntary body movements such as akathisia. Quetiapine has been shown to alleviate symptoms of akathisia; however, its efficacy in the alcohol dependent population is not well established. Thus, we aimed to identify efficacy of Quetiapine in treating akathisia in very heavy drinking alcohol dependent patients. 108 male and female heavy alcohol consuming study participants received 13 weeks of Quetiapine XR. Drinking history (Timeline Followback, TLFB), depression (Montgomery-Asberg Depression Rating Scale, MADRS), and movement (Barnes Akathisia Scale, BARS) measures were collected at baseline (0 W), week 6 (6 W), and week 12 (12 W). The role of drinking, symptoms of depression, and efficacy of Quetiapine for treating akathisia were assessed. In patients with no symptoms of depression (low MADRS), Quetiapine treatment decreased symptoms of akathisia. Patients with clinically significant depression (high MADRS) reported a significant increase in akathisia measures at 6 W which eventually decreased at 12 W to below baseline levels. The increase in akathisia at 6 W corresponded with a significant increase in the patients' total drinks and heavy drinking pattern. Treatment with Quetiapine progressively lowered the occurrence of akathisia in alcohol dependent patients who do not show symptoms of depression. Quetiapine treatment lowered akathisia over time in heavy drinkers who had clinically significant symptoms of depression. PMID:27847671

Alcohol Behavioral Couple Therapy (ABCT) has emerged over the last 30 years as a highly efficacious treatment for those with alcohol use disorders. This review highlights the historical and conceptual underpinnings of ABCT, as well as the specific treatment elements and structure. Proposed active ingredients, moderators, and mediators of treatment outcome are discussed. Efficacy is evaluated for reductions in identified patient drinking, improved relationship functioning, and reductions in intimate partner violence. Adaptations of ABCT for substances other than alcohol are described. Other adaptations, including brief interventions, interventions addressing PTSD and TBI along with alcohol use, and interventions deliverable via technology platforms are described. Additional cost-benefit and cost-effectiveness findings supporting the economic value of ABCT are noted. Future directions for research in this area include possible adaptations for female identified patients, nontraditional couples, LGBT partners and dyads involving nonintimate partner relationships. The development of more flexible models and enhanced dissemination strategies may improve clinical uptake and utility as well as increasing the feasibility of this treatment for integrated healthcare settings.

Background: This study used multi-level analysis to estimate which type of factor explains most of the variance in alcohol consumption of Vietnamese students. Methods: Data were collected among 6011 students attending 12 universities/faculties in four provinces in Vietnam. The three most recent drinking occasions were investigated per student, resulting in 12,795 drinking occasions among 4265 drinkers. Students reported on 10 aspects of the drinking context per drinking occasion. A multi-level mixed-effects linear regression model was constructed in which aspects of drinking context composed the first level; the age of students and four drinking motives comprised the second level. The dependent variable was the number of drinks. Results: Of the aspects of context, drinking duration had the strongest association with alcohol consumption while, at the individual level, coping motive had the strongest association. The drinking context characteristics explained more variance than the individual characteristics in alcohol intake per occasion. Conclusions: These findings suggest that, among students in Vietnam, the drinking context explains a larger proportion of the variance in alcohol consumption than the drinking motives. Therefore, measures that reduce the availability of alcohol in specific drinking situations are an essential part of an effective prevention policy. PMID:27420089

On college campuses, alcohol abuse is a challenge particularly on football game days. From previous research, it is known that fans drink more and are more affected by excessive alcohol consumption than non-fans. This study explored age and gender issues regarding behaviors and consequences of typical game-day alcohol consumption. A…

Underage drinkers typically have not developed regular patterns of drinking and so are likely to exhibit situational variation in alcohol intake, including binge drinking. Information about such variation is not well captured by quantity/frequency (QF) measures, which require that drinkers blend information over time to derive a representative estimate of "typical" drinking. The Timeline Followback (TLFB) method is designed to retrospectively capture situational variations in drinking during a specific period of time. We compared our newly-developed Self-administered TLFB (STLFB) measure to a QF measure for reporting alcohol intake. Our sample of 429 (men=204; women=225) underage (i.e., age 18-20 years) drinkers completed the two drinking measures and reported on alcohol problems. The STLFB and QF measures converged in assessing typical daily intake, but the STLFB provided more information about situational variations in alcohol use and better identification of regular versus intermittent binge drinkers. Regular binge drinkers reported more alcohol problems. The STLFB is an easy-to-administer measure of variations in alcohol intake, which can be useful for understanding drinking behavior.

This study, designed to evaluate a relapse prevention technique, is based on Swedish "heavy" social drinkers who wanted to drink less or quit completely. They were recruited by advertisement in national Swedish newspapers and were randomly assigned into a control group and a coping skill training group (treatment group). Data were collected during the period 1989-1991. Subjects in the coping skills training group were taught methods to cope with the craving for alcohol, and subjects in the control group had a conventional discussion about their problems and the future. All participants also had to set a goal to be reached after the treatment. Subjects were asked about their alcohol consumption and dependence of alcohol and other alcohol-related behaviors, before, six months, and 18 months after treatment. The coping skills training did not prove more efficient than nonspecific treatment received in the control group. Instead alcohol consumption decreased as a function of the subjects' initial goals, independent of treatment and a wish to control drinking seemed more efficient than to try to quit drinking completely.

Alcohol expectancies are a central construct in understanding college student typical alcohol use. However, to our knowledge, there is no research addressing how alcohol expectancies for specific events (i.e. 21st birthday) are different from expectancies regarding typical drinking. We examine the extent to which 21st birthday alcohol expectancies differ from general alcohol expectancies and how 21st birthday expectancies are associated with actual alcohol use and consequences experienced on 21st birthdays, above and beyond expectancies for typical drinking. Participants were college students (N=585; 54% women) who were turning 21 within a week, and intended to drink 4/5 (female/male) drinks on their birthday. All negative expectancies (impairment, risk and aggression, negative self-perception) and positive expectancies (social, liquid courage, sex) except tension reduction were significantly greater for 21st birthday drinking than for typical drinking. While 21st birthday expectancies were not uniquely related to actual birthday drinking, several positive and negative 21st birthday expectancy subscales were associated with 21st birthday drinking-related consequences, even when controlling for typical drinking expectancies. Expectancy challenge interventions aimed specifically at these subscales may be effective at attenuating alcohol-related consequences that result from 21st birthday drinking.

Alcohol use health consequences are considerable; prevention efforts are needed, particularly for adolescents and college students. The national minimum legal drinking age of 21 years is a primary alcohol-control policy in the United States. An advocacy group supported by some college presidents seeks public debate on the minimum legal drinking age and proposes reducing it to 18 years. We reviewed recent trends in drinking and related consequences, evidence on effectiveness of the minimum legal drinking age of 21 years, research on drinking among college students related to the minimum legal drinking age, and the case to lower the minimum legal drinking age. Evidence supporting the minimum legal drinking age of 21 years is strong and growing. A wide range of empirically supported interventions is available to reduce underage drinking. Public health professionals can play a role in advocating these interventions.

Objective The present study attempted to determine if behavioral economic indices of elevated alcohol reward value, measured before and immediately after a brief alcohol intervention, predict treatment response. Method Participants were 133 heavy drinking college students (49.6% female, 51.4% male; 64.3% Caucasian, 29.5% African American) who were randomized to one of three conditions: motivational interviewing plus personalized feedback (BMI), computerized personalized feedback intervention (e-CHUG), and assessment only. Results Baseline levels of alcohol demand significantly predicted drinks per week and alcohol problems at 1-month (demand intensity= maximum expenditure) and 6-month (relative discretionary expenditures on alcohol) follow-up. BMI and e-CHUG were associated with an immediate post-session reduction in alcohol demand (p < .001, ηρ2 = .29) that persisted at the 1-month follow-up, with greater post-session reductions in the BMI condition (p = .02, ηρ2 = .06). Reductions in demand intensity and Omax (maximum expenditure) immediately post-intervention significantly predicted drinking reductions at one-month follow up (p = .04, ΔR2 = .02 & p = .01, ΔR2 = .03, respectively). Reductions in relative discretionary expenditures on alcohol at 1-month significantly predicted drinking (p = .002, ΔR2 = .06,) and alcohol problem (p < .001, ΔR2 = .13) reductions at the 6-month follow-up. Conclusions These results suggest that behavioral economic reward value indices may function as risk factors for poor intervention response and as clinically-relevant markers of change in heavy drinkers.

This study investigated the association between the age at first drink and later alcohol drinking patterns, and analyzed whether differences in the association exist among Korean adults according to gender. The subjects included 10,649 adults (5,405 men and 5,244 women) from the fourth Korean National Health and Nutrition Examination Survey between 2007 and 2009, which extracted the standard survey household by using the proportional systematic sampling method. Baseline individual characteristics, the age at first drink, and individual alcohol drinking patterns were obtained by specially trained interviewers or examiners. The association between the age at first drink and the adult alcohol drinking patterns was summarized with odds ratios and their confidence intervals obtained from multiple logistic regression analysis with sampling weights of KNHANES complex sample survey design. The results of this study show that age, co-habitation, occupation, smoking, and self-rated stress level were significantly related to the drinking patterns for men, whereas education, co-habitation, smoking, and self-rated stress level were significant factors for the drinking patterns of women. The association between the age at first drink and the adult alcohol consumption was significant for both genders and, interestingly, the alcohol drinking patterns were significantly differed by gender even after controlling for the individual characteristics. These results imply a need for gender-specific strategies to prevent hazardous alcohol consumption at a later time for Korean.

Aims To identify childhood and adolescent factors differentiating heavy alcohol users in early adulthood from more moderate users or abstainers. Design Low-income participants followed from birth to age 28 years. Participants A total of 178 adults (95 males) who were first-born children of low-income mothers recruited in Minneapolis, Minnesota, during their third trimester of pregnancy. Measurements Maternal hostility (24/42 months), externalizing and internalizing behavior problems (9 years), peer acceptance and academic achievement (12 years), maternal alcohol use and participants’ drinking behavior (16 years), quantity of alcohol use per occasion (19, 23 and 26 years), alcohol use disorders (28 years). Findings For men: (i) higher amounts of alcohol consumption at age 16 increased the odds of being a heavy drinker compared to an abstainer (age 19) and a moderate drinker (ages 23 and 26); (ii) lower achievement scores at age 12 and having a mother who drank more when the participant was age 16 increased the odds of being a heavy drinker compared to moderate drinker (age 26). Higher levels of externalizing behavior problems at age 9 and drinking more when the participants were age 16 increased the odds that men would have a current alcohol use disorder at age 28. For women: (i) drinking more at age 16 increased the odds of being a heavy drinker compared to being either an abstainer or a moderate drinker (age 26); (ii) having higher levels of achievement at age 12 increased the odds of being a heavy drinker compared to an abstainer at age 23. Adolescent alcohol use mediated the relation between externalizing behavior at age 9 and alcohol use at age 26 for women. Conclusions Problem drinking may be the result of a long-term developmental process wherein childhood externalizing behavior problems sets a pathway leading to heavy drinking during and after adolescence.

Aims: There is sparse literature on drink alcohol content in developing countries. This study documented detailed information on drink sizes and ethanol content of alcoholic beverages consumed in three different parts of India. Methods: Data primarily from formative phases of studies on alcohol use patterns in the states of Delhi, Rajasthan and Goa are reported. Participant observation and semi-structured interviews with key informants and drinking respondents were used to assess different beverage types and to empirically measure actual drink sizes as poured. Investigation of ethanol content included the use of biochemical analyses, the alcoholmeter and the Analox Analyser AM3. Respondents interviewed in the post-formative phase in one study were also asked to define the volume of their drinks by indicating pour levels in select drinking vessels. Results: A wide range of alcoholic drinks were documented that varied in ethanol concentration across and within sites. Drink sizes, particularly for high-strength beverages, varied both by study site and respondent, with pours of distilled spirits on average being larger than standard measures. Conclusion: Estimates of both mean volume of alcohol consumption and heavy drinking amounts are influenced by variability in alcohol concentration and respondent-defined pour sizes. The variation in drink alcohol content found across Indian states indicates that prior to conducting quantitative surveys, preliminary work on sources of drink alcohol content variation should be undertaken to tailor measurement tools to specific beverages and drinking practices observed. Recommendations for alcohol research in developing countries are provided. PMID:18832137

The predominately Hispanic U.S.-Mexico border population is at an elevated risk for drinking and associated problems due to the area's low SES, poor services infrastructure, and drug-related violence. Among Mexican American residents, recent studies suggest this risk is particularly pronounced among younger age groups, and a key characteristic of this elevated risk involves crossing the border to drink in Mexico (where the legal drinking age is 18). However, few studies have compared the drinking behavior of U.S. residents who consume alcohol on the Mexico side of the border with those who do not. We address this gap in the present study. A multistage household probability sample of 1307 Mexican American border residents was interviewed about their drinking and associated problems over the past year. The survey response rate was 67%. Among current drinkers who reported going to Mexico in the past 12 months (N=468), 36.1% reported consuming alcohol in Mexico. Those who drank in Mexico reported significantly more drinks per week (12.8 versus 8.7, p<.05), were more likely to have binged (58.3% versus 35.4%, p<.001), and were more likely to report one or more alcohol problem (35.5% versus 19.5%, p<.01) than those who did not drink in Mexico. Among those who drank in Mexico, men reported significantly more drinks per day while in Mexico than women (6.2 versus 4.0, p<.001). Male gender and lower income were significant predictors of drinking in Mexico. These findings suggest that drinking in Mexico contributes to the heightened risk for drinking and associated problems seen in previous research among Mexican Americans living on the U.S.-Mexico border.

Regular and irregular abuse of alcohol are global health priorities associated with diseases at multiple sites, including cancer. Mechanisms of diseases induced by alcohol are closely related to its metabolism. Among conventional markers of alcohol abuse, the mean corpuscular volume (MCV) of erythrocytes is prognostic of alcohol-related cancer and its predictivity increases when combined with functional polymorphisms of alcohol dehydrogenase (ADH1B [rs1229984] and ADH1C [rs698]) and the mitochondrial aldehyde dehydrogenase (ALDH2 [rs671]). Whether these genetic variants can influence abuse in alcohol drinking and MCV has never been examined in drunk-driving traffic offenders. We examined 149 drunk drivers, diagnosed as alcohol abusers according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth edition Text Revision (DSM-IV-TR) and enrolled in a probation program, and 257 social drinkers (controls), all Caucasian males. Alcohol intake was assessed according to self-reported drink-units/d and MCV unadjusted and adjusted for age, smoking, and body mass index. Multivariable models were used to compute MCV adjusted means. Genotype analyses were performed by PCR on DNA from blood. The adjusted MCV mean was higher in drunk-driving abusers than in controls (92 vs. 91fL; P<.0001) and increased with the number of drink-units/d in both abusers and controls (P-trend=.0316 and .0089) already at intermediate quantities (0-1 vs. 2-4 drink-units/d: P=.054 and .024). Carriers of the common ADH1B*1/*1 (rs1229984) genotype were more likely to be drunk-driving abusers (P=.008), reported higher drink-units/d (P=.0126), and had larger MCV (P=.035). The rs698 ADH1C and rs671 ALDH2 polymorphisms were not associated with MCV. ADH1B*1/*1 polymorphism is significantly associated with being a drunk-driving abuser, higher alcohol drinking, and MCV enlargement. This suggests that drunk drivers with augmented MCV modulated by the alcohol metabolic ADH1B*1/*1 genotype may be at

Prior research suggests that high dispositional self-regulation leads to decreased levels of risky drinking and sexual behavior in adolescence and the early years of college. Self-regulation may be especially important when individuals have easy access to alcohol and freedom to pursue sexual opportunities. In the current 1-year longitudinal study, we followed a sample of N = 1,136 college students who had recently reached the legal age to purchase alcohol and enter bars and clubs to test whether self-regulation protected against heavy episodic drinking, alcohol-related problems, and unprotected sex. We tested main effects of self-regulation and interactions among self-regulation and established risk factors (e.g., sensation seeking) on risky drinking and sexual behavior. High self-regulation inversely predicted heavy episodic drinking, alcohol-related problems, and unprotected sex, even when taking into account gender and risk factors. Moreover, in predicting unprotected sex, we found three-way interactions among self-regulation, sensation seeking, and heavy episodic drinking. Self-regulation buffered against risk associated with heavy drinking but only among those low in sensation seeking. The protective effects of self-regulation for risky drinking and sexual behavior make it a promising target for intervention, with the caveat that self-regulation may be less protective among those who are more drawn to socially and emotionally rewarding stimuli.

To estimate the prevalence of any alcohol use and heavy alcohol drinking using the Alcohol Use Disorders Identification Test (AUDIT) and its correlates among men who have sex with men (MSM), a cross-sectional study was conducted among 391 MSM in Chongqing, China to collect data about sociodemographic characteristics, alcohol use, sexual behaviors, and other related factors through a computer-assisted self-administered questionnaire. Heavy alcohol drinking in the past 12 months was defined as an AUDIT-C score ≥ 4. Blood was collected from each potential participant to test for HIV and syphilis status. Twenty three percent of MSM had consumed a drink containing alcohol in the previous year. 7.2% had an AUDIT-C score ≥ 4, defined as heavy alcohol drinkers. 23.5% were unmarried, but planning to marry, who were more likely to report any alcohol drinking (adjusted odds ratio [AOR], 2.38; 95% confidence interval [CI], 1.40-4.06) and to have AUDIT-C scores ≥ 4 (AOR, 3.58; 95% CI, 1.60-8.00). MSM who had used any alcohol in the previous year, and MSM who were heavy alcohol drinkers, were more likely to have had anal sex with male casual partners in the previous 6 months, to have been tested for HIV, and to have decreased scores on the scales of general self-efficacy, increased scores on the scales of stigma and discrimination. Our findings provided further evidence of the associations of any alcohol use and heavy alcohol consumption with HIV-risky behaviors, lowered sense of general self-efficacy, and higher sense of HIV/AIDS-related stigma and discrimination among MSM in the city with the highest HIV epidemic among MSM in China.

Research indicates that peer and maternal bonds play important but sometimes contrasting roles in the outcomes of children. Less is known about attachment bonds to these 2 reference groups in young adults. Using a sample of 351 participants (18 to 20 years of age), the research integrated two theoretical traditions: attachment theory and theory of planned behavior (TPB). The predictive contribution of both theories was examined in the context of underage adult alcohol use. Using full structural equation modeling, results substantiated the hypotheses that secure peer attachment positively predicted norms and behavioral control toward alcohol, but secure maternal attachment inversely predicted attitudes and behavioral control toward alcohol. Alcohol attitudes, norms, and behavioral control each uniquely explained alcohol intentions, which anticipated an increase in alcohol behavior 1 month later. The hypothesized processes were statistically corroborated by tests of indirect and total effects. These findings support recommendations for programs designed to curtail risky levels of underage drinking using the tenets of attachment theory and TPB.

Background The study aim was to assess the prevalence and co-occurrence of alcohol and sexual risk behaviors among emergency department (ED) patients in community hospitals. Methods Systematic screening of ED patients (N = 6,486; 56.5% female) was conducted in 2 community hospitals in the northeast during times with high patient volume, generally between the hours of 10 AM to 8 PM, Monday through Saturday. Screening occurred from May 2011 through November 2013. Assessment included validated measures of alcohol use and sexual risk behavior. Results Overall results identified high rates of alcohol use, sexual risk behaviors, and their co-occurrence in this sample of ED patients. Specifically, ED patients in between the ages of 18 and 35 were consistently highest in hazardous alcohol use (positive on the Alcohol Use Disorders Identification Test or endorsing heavy episodic drinking [HED]), sexual risk behaviors, and the co-occurrence of alcohol and sex-risk behaviors. Conclusions Findings show a high co-occurrence of hazardous drinking and unprotected sex among ED patients and highlight the role of HED as a factor associated with sexual risk behavior. Efforts to integrate universal screening for the co-occurrence of alcohol and sexual risk behavior in ED settings are warranted; brief interventions delivered to ED patients addressing the co-occurrence of alcohol and sexual risk behaviors have the potential to decrease the risk of sexually transmitted infections and HIV among a large number of patients.

Although the relationship between child maltreatment and alcohol use and drinking problems is well established, the mechanisms involved in this relationship remain largely unknown and research has focused primarily on women. Using the Modified Drinking Motives Questionnaire-Revised (M-DMQ-R; Grant, Stewart, O'Connor, Blackwell & Conrod, 2007), drinking motives were examined as mediators in the relationship between childhood maltreatment and alcohol consumption and consequences among male and female college student drinkers (N = 218, 60.6% women). Participants completed questionnaires assessing child maltreatment, drinking motives, alcohol consumption and alcohol consequences. Enhancement motives in particular mediated the relationship between childhood abuse and alcohol consequences for men, whereas coping-depression motives mediated this relationship for women. Implications of these findings for alcohol interventions and future research are discussed, along with limitations of the present study.

Problem drinkers may use alcohol to avoid negative mood states and may develop implicit cognitive associations between negative emotional states and reinforcing properties of drinking. It is paradoxical that attempts to control drinking, such as among those high in drinking restraint, may inadvertently increase desire to drink and subsequent alcohol consumption, and this may be exaggerated under times of emotional distress when urges to drink are high. We examined whether individuals who are high on drinking restraint would demonstrate stronger alcohol-related thoughts elicited by stimuli that represent the desire to use alcohol, in response to stronger versus weaker negative mood arousal. Seventy hazardous drinkers completed measurements of drinking restraint, alcohol consumption, and consequences of use. After being randomized to view negative or positive pictures sets, participants completed an Implicit Association Task (IAT) to test differences in the strength of the association between desire to approach or avoid alcohol or water cues, and then a measurement of subjective craving following the IAT. Regression analyses showed that trait restriction not temptation was positively related to IAT scores, after controlling for relevant covariates and explained 7% of the total variance. Trait temptation not IAT predicted subjective craving. Negative affect was unrelated to IAT scores, singly or in conjunction with measures of drinking restraint, contrary to predictions. In sum, implicit alcohol cognitions are related to attempts to restrict drinking not temptation to drink and are less strongly influenced by mood state.

Problem drinkers may use alcohol to avoid negative mood states and may develop implicit cognitive associations between negative emotional states and reinforcing properties of drinking. Ironically, attempts to control drinking, such as among those high in drinking restraint, may inadvertently increase desire to drink and subsequent alcohol consumption, and this may be exaggerated under times of emotional distress when urges to drink are high. We examined whether individuals who are high on drinking restraint would demonstrate stronger alcohol-related thoughts elicited by stimuli that represent the desire to use alcohol, in response to stronger versus weaker negative mood arousal. Seventy hazardous drinkers completed measurements of drinking restraint, alcohol consumption, and consequences of use. After being randomized to view negative or positive pictures sets, participants completed an Implicit Association Task (IAT) to test differences in the strength of the association between desire to approach or avoid alcohol or water cues, and then a measurement of subjective craving following the IAT. Regression analyses showed that trait restriction, but not temptation, was positively related to IAT scores, after controlling for relevant covariates and explained 7% of the total variance. Trait temptation, but not IAT, predicted subjective craving. Negative affect was unrelated to IAT scores, singly or in conjunction with measures of drinking restraint, contrary to predictions. In sum, implicit alcohol cognitions are related to attempts to restrict drinking, but not temptation to drink, and are less strongly influenced by mood state. PMID:22369223

The transition from goal-directed actions to habitual ethanol seeking models the development of addictive behavior that characterizes alcohol use disorders. The progression to habitual ethanol-seeking behavior occurs more rapidly than for natural rewards, suggesting that ethanol may act on habit circuit to drive the loss of behavioral flexibility. This review will highlight recent research that has focused on the formation and expression of habitual ethanol seeking, and the commonalities and distinctions between ethanol and natural reward-seeking habits, with the goal of highlighting important, understudied research areas that we believe will lead toward the development of novel treatment and prevention strategies for uncontrolled drinking.

Alcohol has been implicated in the high mortality in Central and Eastern Europe but the magnitude of its effect, and whether it is due to regular high intake or episodic binge drinking remain unclear. The aim of this paper was to estimate the contribution of alcohol to mortality in four Central and Eastern European countries. We used data from the Health, Alcohol and Psychosocial factors in Eastern Europe is a prospective multi-centre cohort study in Novosibirsk (Russia), Krakow (Poland), Kaunas (Lithuania) and six Czech towns. Random population samples of 34,304 men and women aged 45-69 years in 2002-2005 were followed up for a median 7 years. Drinking volume, frequency and pattern were estimated from the graduated frequency questionnaire. Deaths were ascertained using mortality registers. In 230,246 person-years of follow-up, 2895 participants died from all causes, 1222 from cardiovascular diseases (CVD), 672 from coronary heart disease (CHD) and 489 from pre-defined alcohol-related causes (ARD). In fully-adjusted models, abstainers had 30-50% increased mortality risk compared to light-to-moderate drinkers. Adjusted hazard ratios (HR) in men drinking on average ≥60 g of ethanol/day (3% of men) were 1.23 (95% CI 0.95-1.59) for all-cause, 1.38 (0.95-2.02) for CVD, 1.64 (1.02-2.64) for CHD and 2.03 (1.28-3.23) for ARD mortality. Corresponding HRs in women drinking on average ≥20 g/day (2% of women) were 1.92 (1.25-2.93), 1.74 (0.76-3.99), 1.39 (0.34-5.76) and 3.00 (1.26-7.10). Binge drinking increased ARD mortality in men only. Mortality was associated with high average alcohol intake but not binge drinking, except for ARD in men.

Sardinian alcohol-preferring (sP) rats have been selectively bred for high alcohol preference and consumption using the standard 2-bottle "alcohol (10%, v/v) vs. water" choice regimen with unlimited access; under this regimen, sP rats daily consume 6-7 g/kg alcohol. The present study assessed a new paradigm of alcohol intake in which sP rats were exposed to the 4-bottle "alcohol (10%, 20%, and 30%, v/v) vs. water" choice regimen during one of the 12 h of the dark phase of the daily light/dark cycle; the time of alcohol exposure was changed daily in a semi-random order and was unpredictable to rats. Alcohol intake was highly positively correlated with the time of the drinking session and averaged approximately 2 g/kg when the drinking session occurred during the 12th hour of the dark phase. Alcohol drinking during the 12th hour of the dark phase resulted in (a) blood alcohol levels averaging approximately 100 mg% and (b) severe signs of alcohol intoxication (e.g., impaired performance at a Rota-Rod task). The results of a series of additional experiments indicate that (a) both singular aspects of this paradigm (i.e., unpredictability of alcohol exposure and concurrent availability of multiple alcohol concentrations) contributed to this high alcohol intake, (b) alcohol intake followed a circadian rhythm, as it decreased progressively over the first 3 h of the light phase and then maintained constant levels until the beginning of the dark phase, and (c) sensitivity to time schedule was specific to alcohol, as it did not generalize to a highly palatable chocolate-flavored beverage. These results demonstrate that unpredictable, limited access to multiple alcohol concentrations may result in exceptionally high intakes of alcohol in sP rats, modeling - to some extent - human binge drinking. A progressively increasing emotional "distress" associated to rats' expectation of alcohol might be the neurobehavioral basis of this drinking behavior.

Objective: To understand the association of alcohol use with sex and unprotected sex among hazardously drinking incarcerated women, we examined the relationship of these behaviors on any given day. Method: Participants endorsed unprotected sex and hazardous alcohol consumption (four or more drinks at a time on at least 3 separate days in the previous 3 months or a score of 8 or above on the Alcohol Use Disorders Identification Test). Participants recalled behaviors in the 90 days before incarceration using the Timeline Followback method. Generalized estimating equation models estimated the effect of daily alcohol use and selected covariates on the odds of sexual-risk behavior. Results: The 245 participants averaged 34 years of age and were 71.4% white; 67.8% used cocaine. On most (84.7%) drinking days, women consumed four or more drinks. One hundred forty-one participants (57.6%) reported sex with only main partners, 10.6% with only casual partners, and 30.6% with both casual and main partners. The likelihood of having any sex (odds ratio = 1.78, p < .01) and unprotected sex (odds ratio = 1.95, p < .01) was higher on days when participants consumed alcohol compared with nondrinking days. However, when the analysis was restricted to days on which participants reported having sex, the odds of having unprotected sex was not significantly associated with drinking. Conclusions: Among incarcerated women who reported hazardous drinking, alcohol use was associated with an increased likelihood of sexual activity and a concomitant increase in unprotected sex. However, use of alcohol was not significantly associated with condom use on days when participants were sexually active. PMID:19515290

Binocular rivalry refers to perceptual alternation when two eyes view different images. One of the potential percepts during binocular rivalry is a spatial mosaic of left- and right-eye images, known as piecemeal percepts, which may result from localized rivalries between small regions in the left- and right-eye images. It is known that alcohol increases inhibitory neurotransmission, which may reduce the number of alternations during binocular rivalry. However, it is unclear whether alcohol affects rivalry dynamics in the same manner for both coherent percepts (i.e., percepts of complete left or right images) and piecemeal percepts. To address this question, the present study measured the dynamics of binocular rivalry before and after 15 moderate-to-heavy social drinkers consumed an intoxicating dose of alcohol versus a placebo beverage. Both simple rivalrous stimuli consisting of gratings with different orientations, and complex stimuli consisting of a face or a house were tested to examine alcohol effects on rivalry as a function of stimulus complexity. Results showed that for both simple and complex stimuli, alcohol affects coherent and piecemeal percepts differently. More specifically, alcohol reduced the number of coherent percepts but not the mean dominance duration of coherent percepts. In contrast, for piecemeal percepts, alcohol increased the mean dominance duration but not the number of piecemeal percepts. These results suggested that alcohol drinking may selectively affect the dynamics of transitional period of binocular rivalry by increasing the duration of piecemeal percepts, leading to a reduction in the number of coherent percepts. The differential effect of alcohol on the dynamics of coherent and piecemeal percepts cannot be accounted for by alcohol’s effect on a common inhibitory mechanism. Other mechanisms, such as increasing neural noise, are needed to explain alcohol’s effect on the dynamics of binocular rivalry. PMID:27092096

Background The P2X4 receptor is thought to be involved in regulating alcohol-consuming behaviors and ethanol (EtOH) has been reported to inhibit P2X4 receptors. Ivermectin is an anti-parasitic agent that acts as a positive allosteric modulator of the P2X4 receptor. The current study examined the effects of systemically- and centrally-administered ivermectin on alcohol drinking of replicate lines of high-alcohol-drinking (HAD-1/HAD-2) rats, and the effects of lentiviral-delivered short-hairpin RNAs (shRNAs) targeting P2rx4 on EtOH intake of female HAD2 rats. Method For the 1st experiment, adult male HAD-1 & HAD-2 rats were given 24-hr free-choice access to 15% EtOH vs. water. Dose-response effects of ivermectin (1.5 to 7.5 mg/kg i.p.) on EtOH intake were determined; the effects of ivermectin were then examined for 2% w/v sucrose intake over 5 consecutive days. In the 2nd experiment, female HAD-2 rats were trained to consume 15% EtOH under 2-hr limited access conditions, and dose-response effects of intracerebroventricular (ICV) administration of ivermectin (0.5 to 2.0 μg) were determined over 5 consecutive days. The 3rd experiment determined the effects of microinfusion of a lentivirus expressing P2rx4 shRNAs into the posterior ventral tegmental area (VTA) on 24-hr EtOH free-choice drinking of female HAD-2 rats. Results The highest i.p. dose of ivermectin reduced alcohol drinking (30-45%) in both rat lines, but did not alter sucrose intake. HAD-2 rats appeared to be more sensitive than HAD1 rats to the effects of ivermectin. ICV administration of ivermectin reduced 2-hr limited access intake (∼35%) of female HAD-2 rats; knockdown of P2rx4 expression in the posterior VTA reduced 24-hr free choice EtOH intake (∼20%). Conclusion Overall, the results of the current study support a role for P2X4 receptors within the mesolimbic system in mediating alcohol drinking behavior. PMID:26334550

FKBP5 encodes FK506-binding protein 5, a glucocorticoid receptor (GR)-binding protein implicated in various psychiatric disorders and alcohol withdrawal severity. The purpose of this study is to characterize alcohol preference and related phenotypes in Fkbp5 knockout (KO) mice and to examine the role of FKBP5 in human alcohol consumption. The following experiments were performed to characterize Fkpb5 KO mice. (1) Fkbp5 KO and wild-type (WT) EtOH consumption was tested using a two-bottle choice paradigm; (2) The EtOH elimination rate was measured after intraperitoneal (IP) injection of 2.0 g/kg EtOH; (3) Blood alcohol concentration (BAC) was measured after 3 h limited access of alcohol; (4) Brain region expression of Fkbp5 was identified using LacZ staining; (5) Baseline corticosterone (CORT) was assessed. Additionally, two SNPs, rs1360780 (C/T) and rs3800373 (T/G), were selected to study the association of FKBP5 with alcohol consumption in humans. Participants were college students (n = 1162) from 21-26 years of age with Chinese, Korean or Caucasian ethnicity. The results, compared to WT mice, for KO mice exhibited an increase in alcohol consumption that was not due to differences in taste sensitivity or alcohol metabolism. Higher BAC was found in KO mice after 3 h of EtOH access. Fkbp5 was highly expressed in brain regions involved in the regulation of the stress response, such as the hippocampus, amygdala, dorsal raphe and locus coeruleus. Both genotypes exhibited similar basal levels of plasma corticosterone (CORT). Finally, single nucleotide polymorphisms (SNPs) in FKBP5 were found to be associated with alcohol drinking in humans. These results suggest that the association between FKBP5 and alcohol consumption is conserved in both mice and humans.

Several decades of research show that lesbians are at risk for hazardous drinking. Compared with heterosexual women, lesbians are less likely to abstain from drinking, less likely to decrease their alcohol consumption as they age, and more likely to report alcohol-related problems. Stress associated with lesbian identity and reliance on lesbian or gay bars for socialization and support are frequently posited--but largely untested--explanations for lesbians' heightened risk. Results from general population studies indicate that patterns of alcohol use established early in the life-course or during life transitions influence later alcohol use and alcohol-related problems. Further, heavy-drinking peers, availability of alcohol, and drinking in particular social contexts--such as at bars and parties--are believed to contribute to heavier drinking and to alcohol-related problems. To better understand lesbians' risks for hazardous drinking, we examined relationships between retrospective accounts of drinking patterns and drinking contexts in the early stages of lesbian identity development and current drinking outcomes in a large sample of adult lesbians. Findings suggest that early drinking patterns and drinking contexts influence later alcohol use and have important implications for risk reduction and prevention among lesbians.

Evidence that persons with HIV who reside in states with stricter DUI penalties drink less might suggest that changes to alcohol policy might improve the health of persons with HIV and reduce the rate of new infections. Using multi-level modeling and data from the national HIV Cost and Services Utilization Study, we examined how states' DUI-related fines, jail time, license suspension, and court-referred treatment/education policies were related to past month drinking/not (n = 2,255) and among drinkers (n = 1,117), drinking frequency, drinks per occasion, and engagement in frequent heavy drinking. Fine strictness was negatively related to all outcomes. Residents in states with court-referred treatment/education had more current drinkers. Results suggested that punitive DUI policies might curb a variety of drinking behaviors whereas harm reduction DUI policies (e.g., court treatment programs) might have been established in response to higher drinking rates.

The purpose of this paper is to investigate the relationships between illicit drug and alcohol use, problem drinking, and road rage. Particular attention is devoted to the association between these behaviors and frequent involvement in road rage activities. The data are taken from the 2002 Centre for Addiction and Mental Health (CAMH) Monitor, a representative telephone survey with a sample of 2421 adults aged 18 and older in Ontario. A cluster analysis was performed and analysis of variance procedures were used to test for group differences. The cluster analysis revealed five distinct groups involved in various types of road rage behavior. Frequent road ragers, accounting for 5.3% of the sample, were involved in the most severe forms of road rage behavior and were most likely (24%) to report problem drinking and past year cannabis (23.8%), cocaine (5.4%), and ecstasy (10%) use. These data indicate that illicit drug use and alcohol problems are significantly greater for those involved in the most serious forms of road rage behavior. Further work is needed to identify the mechanisms by which illicit drug use and problem drinking are linked to road rage.

To examine the effects of alcohol consumption on female sexuality and contraceptive use, 69 sexually active women between the ages of 18 and 34 completed daily logs of their drinking behavior, sexual activity and contraceptive use over three consecutive menstrual cycles. In addition, participants completed a post-study questionnaire that assessed personal beliefs regarding alcohol use and sexual behavior. Although the results from the daily logs failed to show any significant effects of alcohol on subsequent sexual arousal, sexual pleasure or orgasm, female-initiated sexual activity appeared to be inversely related to alcohol use with women initiating significantly fewer sexual activities following the consumption of alcohol. On the contrary, the retrospective questionnaire data indicated that women believed alcohol enhanced sexual desire, enjoyment and activity. The findings further indicated that alcohol consumption immediately prior to sexual intercourse did not significantly alter the use of coitus-dependent contraceptives. These data suggest that women view alcohol as an aphrodisiac despite their physiological and reported behavioral responses.

This study examined underage drinkers' responses to negative-restrictive versus proactive-nonrestrictive slogans in humorous anti-alcohol abuse advertisements. The authors conducted a posttest-only control group experiment with 91 teenagers and college-aged participants. For underage moderate drinkers, the negative-restrictive slogans (e.g., "Don't drink") increased participants' perceived risk of excessive drinking and increased a level of intention to change their drinking behavior. However, for underage binge drinkers, the negative-restrictive slogans lowered participants' risk perception of excessive drinking and intention to change their drinking behavior.

Alcohol (ethanol) dependence is a chronic relapsing brain disorder partially influenced by genetics and characterized by an inability to regulate harmful levels of drinking. Emerging evidence has linked genes that encode KV7, KIR, and KCa2 K(+) channels with variation in alcohol-related behaviors in rodents and humans. This led us to experimentally test relations between K(+) channel genes and escalation of drinking in a chronic-intermittent ethanol (CIE) exposure model of dependence in BXD recombinant inbred strains of mice. Transcript levels for K(+) channel genes in the prefrontal cortex (PFC) and nucleus accumbens (NAc) covary with voluntary ethanol drinking in a non-dependent cohort. Transcripts that encode KV7 channels covary negatively with drinking in non-dependent BXD strains. Using a pharmacological approach to validate the genetic findings, C57BL/6J mice were allowed intermittent access to ethanol to establish baseline consumption before they were treated with retigabine, an FDA-approved KV7 channel positive modulator. Systemic administration significantly reduced drinking, and consistent with previous evidence, retigabine was more effective at reducing voluntary consumption in high-drinking than low-drinking subjects. We evaluated the specific K(+) channel genes that were most sensitive to CIE exposure and identified a gene subset in the NAc and PFC that were dysregulated in the alcohol-dependent BXD cohort. CIE-induced modulation of nine genes in the NAc and six genes in the PFC covaried well with the changes in drinking induced by ethanol dependence. Here we identified novel candidate genes in the NAc and PFC that are regulated by ethanol dependence and correlate with voluntary drinking in non-dependent and dependent BXD mice. The findings that Kcnq expression correlates with drinking and that retigabine reduces consumption suggest that KV7 channels could be pharmacogenetic targets to treat individuals with alcohol addiction.

Research has consistently found that religiousness and spirituality are negatively associated with underage drinking. However, there is a paucity of research exploring the mechanisms by which these variables influence this important outcome. With 344 underage young adults (ages 18-20; 61 % women), we investigated positive alcohol expectancies as a mediator between religiousness and spirituality (measured separately) and underage alcohol use. Participants completed the Religious Commitment Inventory-10, Daily Spiritual Experiences Scale, Alcohol Expectancies Questionnaire, and Drinking Styles Questionnaire. Results indicate less positive alcohol expectancies partially mediate the relationship between both religiousness and spirituality and underage alcohol use. This suggests religiousness and spirituality's protective influence on underage drinking is partly due to their influence on expectations about alcohol's positive effects. Since underage drinking predicts problem drinking later in life and places one at risk for serious physical and mental health problems, it is important to identify specific points of intervention, including expectations about alcohol that rise from religious and spiritual factors.

Objective: A high proportion of individuals convicted of driving under the influence (DUI) are repeat offenders. Efforts have sought to identify specific factors underlying DUI recidivism. Of particular interest is the role that alcohol-related cognitions might play in the development and escalation of alcohol use. The present study investigated the degree to which preoccupation with, and attentional bias to, alcohol are heightened among repeat DUI offenders. Method: Three groups of participants (recidivist DUI offenders, first-time offenders, and controls; n = 20 per group) performed a visual probe task to measure attentional bias and completed questionnaires regarding their cognitive and emotional preoccupation with alcohol and drinking habits. Results: Recidivist offenders displayed a significantly heightened alcohol attentional bias and reported greater preoccupation with alcohol compared with both first-time offenders and controls. By contrast, none of the groups differed with regard to the self-reported quantity and frequency of their consumption. Conclusions: Factors reflecting preoccupation with alcohol have utility for differentiating recidivist offenders from both first-time offenders and nonoffenders. These findings highlight the value of moving beyond self-reported assessments of drinking patterns toward assessing specific cognitive and behavioral characteristics that can improve our understanding, assessment, and treatment of the problem of DUI recidivism.

The anabolic steroid nandrolone decanoate has been reported to increase voluntary ethanol intake in Wistar rats. In recent experiments we received opposite results, with decreased voluntary ethanol intake in both high drinking AA and low drinking Wistar rats after nandrolone treatment. The difference between the two studies was that we used pure nandrolone decanoate in oil, whereas in the previous study the nandrolone product Deca-Durabolin containing benzyl alcohol (BA) was used. The aims of the present study were to clarify whether the BA treatment could promote ethanol drinking and to assess the role of the hypothalamic-pituitary-adrenal-gonadal axes (HPAGA) in the potential BA effect. Male AA and Wistar rats received subcutaneously BA or vehicle oil for 14 days. Hereafter followed a 1-week washout and consecutively a 3-week voluntary alcohol consumption period. The median (± median absolute deviation) voluntary ethanol consumption during the drinking period was higher in BA-treated than in control rats (4.94 ± 1.31 g/kg/day vs. 4.17 ± 0.31 g/kg/day, p = 0.07 and 1.01 ± 0.26 g/kg/day vs. 0.38 ± 0.27 g/kg/day, p = 0.05, for AA and Wistar rats, respectively; combined effect p < 0.01). The present results can explain the previous discrepancy between the two nandrolone studies. No significant BA effects on basal and ethanol-mediated serum testosterone and corticosterone levels were observed in blood samples taken at days 1, 8 and 22. However, 2h after ethanol administration significantly (p = 0.02) higher frequency of testosterone elevations was detected in high drinking AA rats compared to low drinking Wistars, which supports our previous hypotheses of a role of testosterone elevation in promoting ethanol drinking. Skin irritation and dermatitis were shown exclusively in the BA-treated animals. Altogether, the present results indicate that earlier findings obtained with Deca-Durabolin containing BA need to be re-evaluated.

Three pairs of Indiana University rat lines (inbred alcohol-preferring and nonpreferring rat lines [P/NPs], high- and low-alcohol-drinking rat lines [HAD/LAD1s and HAD/LAD2s]) were bred in the School of Medicine colony to drink high versus low daily amounts of a 10% vol/vol alcohol test solution (>5.0 g/kg body weight vs. <1.5 g/kg body weight), and a high versus low proportion of alcohol to water (>2:1 vs. <0.5:1) by the end of a 3-week alcohol-water choice condition. This choice phase was always preceded by four days of a forcing procedure with alcohol as the only fluid. The present study examined the contribution of the forcing procedure to the alcohol intake of animals in each pair of lines by comparing daily alcohol intake of rats housed in experimental chambers in a forced group (4 days with only alcohol solution to drink followed by 22 choice days) versus a choice group (both alcohol and water available all 26 days). As expected, under the initial alcohol exposure, high-drinking line rats drank more alcohol than low-drinking line rats, and all forced groups drank more alcohol than choice groups. At the start of the choice phase, all low-drinking line forced groups immediately dropped their alcohol intake to the level of their choice groups. In contrast, all high-drinking line forced groups maintained a high level of alcohol intake under choice, whereas all high-drinking line choice groups slowly increased average alcohol intake across the 22-day choice phase, ending near the average intake of their forced groups. However, a small subset of each high-drinking line choice animals failed to increase alcohol intake until subsequently forced with alcohol for 4 days and tested again in choice. These results indicate that the alcohol-forcing procedure used in deriving these lines resulted in the selection of more than one pathway to a high-drinking phenotype. In addition, high-drinking line animals appeared more sensitive to the differences between laboratory- and

Alcohol and nicotine are the two most co-abused drugs in the world. Previous studies have shown that nicotine can increase alcohol drinking in nondependent rats, yet it is unknown whether nicotine facilitates the transition to alcohol dependence. We tested the hypothesis that chronic nicotine will speed up the escalation of alcohol drinking in rats and that this effect will be accompanied by activation of sparsely distributed neurons (neuronal ensembles) throughout the brain that are specifically recruited by the combination of nicotine and alcohol. Rats were trained to respond for alcohol and made dependent using chronic, intermittent exposure to alcohol vapor, while receiving daily nicotine (0.8 mg/kg) injections. Identification of neuronal ensembles was performed after the last operant session, using immunohistochemistry. Nicotine produced an early escalation of alcohol drinking associated with compulsive alcohol drinking in dependent, but not in nondependent rats (air exposed), as measured by increased progressive-ratio responding and increased responding despite adverse consequences. The combination of nicotine and alcohol produced the recruitment of discrete and phenotype-specific neuronal ensembles (∼4-13% of total neuronal population) in the nucleus accumbens core, dorsomedial prefrontal cortex, central nucleus of the amygdala, bed nucleus of stria terminalis, and posterior ventral tegmental area. Blockade of nicotinic receptors using mecamylamine (1 mg/kg) prevented both the behavioral and neuronal effects of nicotine in dependent rats. These results demonstrate that nicotine and activation of nicotinic receptors are critical factors in the development of alcohol dependence through the dysregulation of a set of interconnected neuronal ensembles throughout the brain.

Teenage mothers are more likely to use drugs, and their children are more likely to use substances and become pregnant during adolescence. Teenage mothers' substance use may play a role in the intergenerational risk for adolescent pregnancy. Pregnant adolescents (12-18 years) were seen during pregnancy and postnatal years 6, 10, 14, and 16 (n = 332). Teenage mothers reported on substance use and family characteristics. The offspring reported substance use (starting at age 10) and sexual behavior (ages 14 and 16). Prenatal alcohol exposure was associated with offspring (a) having a risky first sex partner and (b) multiple sex partners in the past year. Heavy maternal drinking during childhood was associated with offspring reports of a risky first sex partner and early teenage pregnancy. Findings from this unique birth cohort have implications for alcohol prevention efforts with girls during and after a teenage pregnancy and interventions to prevent risky sex in high-risk youth.

Experimentation with alcohol and sexuality is a normative aspect of adolescent development. Yet both present distinct risks to adolescent females and are especially problematic when they intersect. Although youth are often cautioned about the dangers associated with having sex and using alcohol, popular entertainment media frequently depict the combination of alcohol and sexuality as carefree fun. It is unclear how adolescent females interpret these contradictory messages in their everyday lives. Focus group interviews were used to explore young women's understandings of the relation between alcohol and sexuality. Young women, ages 14–17 years (N = 97, 61% White), and their mothers were recruited through advertisements in local newspapers to participate in separate, simultaneous focus group interviews. Only data from the 15 daughters' groups are presented here. Qualitative analysis revealed that participants recognized the risks associated with combining alcohol and sex, yet they also perceived sexual advantages to drinking alcohol. Advantages included facilitating social and sexual interactions and excusing unsanctioned sexual behavior. Alcohol was also seen as increasing the likelihood of sexual regret and coercion through impaired judgment and self-advocacy abilities. Educational and prevention efforts need to consider adolescent developmental and social needs, as well as the influences of the larger cultural context in which youth function. PMID:23833392

Study describes the blockade of relapse-like alcohol drinking by mesenchymal stem cells (MSCs). High alcohol-intake bred rats consumed alcohol for 3 months and were subjected to repeated alcohol deprivations for 7-14 days, followed by alcohol reaccess. Upon reaccess, animals consumed 2.2 g alcohol/kg in 60 minutes. A single intra-cerebroventricular MSC administration inhibited relapse-like drinking up to 80-85% for 40 days (P < 0.001). An alcohol-use-disorder was prevented.

Neuroeconomics integrates concepts and methods from psychology, economics, and cognitive neuroscience to understand how the brain makes decisions. In economics, demand refers to the relationship between a commodity's consumption and its cost, and, in behavioral studies, high alcohol demand has been consistently associated with greater alcohol misuse. Relatively little is known about how the brain processes demand decision making, and the current study is an initial investigation of the neural correlates of alcohol demand among heavy drinkers. Using an event-related functional magnetic resonance imaging (fMRI) paradigm, participants (N=24) selected how much they would drink under varying levels of price. These choices determined access to alcohol during a subsequent bar laboratory self-administration period. During decisions to drink in general, greater activity was present in multiple distinct subunits of the prefrontal and parietal cortices. In contrast, during decisions to drink that were demonstrably affected by the cost of alcohol, significantly greater activation was evident in frontostriatal regions, suggesting an active interplay between cognitive deliberation and subjective reward value. These choices were also characterized by significant deactivation in default mode network regions, suggesting suppression resulting from greater cognitive load. Across choice types, the anterior insula was notably recruited in diverse roles, further implicating the importance of interoceptive processing in decision-making behavior. These findings reveal the neural signatures subserving alcohol cost-benefit decision making, providing a foundation for future clinical applications of this paradigm and extending this approach to understanding the neural correlates of demand for other addictive commodities.
Background Research indicates that brief motivational interventions are efficacious treatments for hazardous drinking. Little is known, however, about the psychological processes that may moderate intervention success. Based on growing evidence that drinking behavior may be influenced by automatic (nonvolitional) mental processes, the current study examined whether automatic alcohol-approach associations moderated the effect of a brief motivational intervention. Specifically, we examined whether the efficacy of a single-session intervention designed to increase motivation to reduce alcohol consumption would be moderated by the strength of participants’ automatic alcohol-approach associations. Methods Eighty-seven undergraduate hazardous drinkers participated for course credit. Participants completed an Implicit Association Test to measure automatic alcohol-approach associations, a baseline measure of readiness to change drinking behavior, and measures of alcohol involvement. Participants were then randomly assigned to either a brief (15-minute) motivational intervention or a control condition. Participants completed a measure of readiness to change drinking at the end of the first session and returned for a follow-up session six weeks later in which they reported on their drinking over the previous month. Results Compared with the control group, those in the intervention condition showed higher readiness to change drinking at the end of the baseline session but did not show decreased drinking quantity at follow-up. Automatic alcohol-approach associations moderated the effects of the intervention on change in drinking quantity. Among participants in the intervention group, those with weak automatic alcohol-approach associations showed greater reductions in the amount of alcohol consumed per occasion at follow-up compared with those with strong automatic alcohol-approach associations. Automatic appetitive associations with alcohol were not related with change in

This study tested a modified version of the Alcohol-Related Behavior Questionnaire (ARBQ) to investigate the influence of alcohol on negative mood states. The ARBQ asked subjects (substance users and those not misusing drugs or alcohol) to recall various moods and behaviors under three drug conditions: sober, drinking, and drunk. Tests of the ARBQ subscales provided support for its reliability and validity. Scale scores measuring negative affect increased as levels of recalled alcohol intake increased, suggesting that larger amounts of alcohol produced more negative and aggressive feelings. Alcohol-dependent subjects reported more anger and aggression with increasing levels of alcohol intake than nonproblem drinkers. These data further indicated that, among those with alcohol dependence, a history of childhood aggression is an important predictor of negative behaviors and feelings associated with alcohol intake. Among other groups of drug users, a diagnosis of antisocial personality was relatively more important.

Introduction The aim of this survey was to assess the motives for energy drink consumption, both alone and mixed with alcohol, and to determine whether negative or neutral motives for consuming alcohol mixed with energy drinks (AMED) have a differential effect on overall alcohol consumption. Methods Demographics, alcohol and energy drink consumption-related questions, and motives for the consumption of energy drinks (alone or mixed with alcohol) were assessed. The motives to mix alcohol with energy drinks were compared with those for mixing alcohol with other nonalcoholic beverages. Results A total of 2,329 students who completed the study consumed energy drinks. The motives for consuming energy drinks (without alcohol) included “I like the taste” (58.6%), “To keep me awake” (54.3%), “It gives me energy” (44.3%), “It helps concentrating when studying” (33.9%), “It increases alertness” (28.8%), “It helps me concentrate better” (20.6%), and “It makes me less sleepy when driving” (14.2%). A total of 1,239 students reported occasionally consuming AMED (AMED group). The most frequent motives included “I like the taste” (81.1%), “I wanted to drink something else” (35.3%), and “To celebrate a special occasion” (14.6%). No relevant differences in motives were observed for using an energy drink or another nonalcoholic beverage as a mixer. A minority of students (21.6%) reported at least one negative motive to consume AMED. Despite these negative motives, students reported consuming significantly less alcohol on occasions when they consumed AMED compared to alcohol-only occasions. Conclusion The majority of students who consume energy drinks (without alcohol) do so because they like the taste, or they consume these drinks to keep them awake and give them energy. AMED consumption is more frequently motivated by neutral as opposed to negative motives. No relevant differences in drinking motives and overall alcohol consumption were

The development of tolerance to alcohol with chronic consumption is an important criterion for an animal model of alcoholism and may be an important component of the genetic predisposition to alcoholism. The aim of this study was to determine whether the selectively bred Warsaw High Preferring (WHP) line of alcohol-preferring rats would develop behavioral and metabolic tolerance during the free-choice drinking of ethanol. Chronic tolerance to ethanol-induced sedation was tested. The loss of righting reflex (LRR) paradigm was used to record sleep duration in WHP rats. Ethanol (EtOH)-naive WHP rats received a single intraperitoneal (i.p.) injection of 5.0 g ethanol/kg body weight (b.w.), and sleep duration was measured. Subsequently, rats had access to a 10% ethanol solution under a free-choice condition with water and food for 12 weeks. After 12 weeks of the free-choice intake of ethanol, the rats received another single i.p. injection of 5.0 g ethanol/kg b.w., and sleep duration was reassessed. The blood alcohol content (BAC) for each rat was determined after an i.p. injection of 5 g/kg of ethanol in naive rats and again after chronic alcohol drinking at the time of recovery of the righting reflex (RR). The results showed that the mean ethanol intake was 9.14 g/kg/24 h, and both sleep duration and BAC were decreased after chronic ethanol intake. In conclusion, WHP rats exposed to alcohol by free-choice drinking across 12 weeks exhibited increased alcohol elimination rates. Studies have demonstrated that WHP rats after chronic free-choice drinking (12 weeks) of alcohol develop metabolic tolerance. Behavioral tolerance to ethanol was demonstrated by reduced sleep duration, but this decrease in sleep duration was not significant.

Young adults and young women in particular are drinking more alcohol than ever before, with implications for risky behaviours and long-term health. This study explored the ways in which alcohol and drinking were represented in six monthly UK magazines (three targeted at young men, three at young women) across a three-month period (18 magazines). We identified three main discourses across the texts, namely the drug alcohol; masculinity and machismo; and drinking as normality. These discourses constructed women's and men's drinks and drinking behaviours in sharp contrast. Drinking was aligned with traditional masculine images, although new kinds of drinks were aligned with traditional feminine images--and derided in men's magazines. Findings highlight how gender, constructed in relation to the other, is an important aspect of representations of drinking patterns in young adults.

Background Exposure to alcohol marketing is prevalent and is associated with both initiation and progression of alcohol use in underage youth. The mechanism of influence is not well understood, however. This study tests a model that proposes alcohol-specific cognitions as mediators of the relation between alcohol marketing and problematic drinking among experimental underage drinkers. Methods This paper describes a cross-sectional analysis of 1734 U.S. 15–20 year old underage drinkers, recruited for a national study of media and substance use. Subjects were queried about a number of alcohol marketing variables including television time, internet time, favorite alcohol ad, ownership of alcohol branded merchandise (ABM), and exposure to alcohol brands in movies. The relation between these exposures and current (30 day) binge drinking was assessed, as were proposed mediators of this relation, including marketing-specific cognitions (drinker identity and favorite brand to drink), favorable alcohol expectancies and alcohol norms. Paths were tested in a structural equation model that controlled for socio-demographics, personality and peer drinking. Results Almost one-third of this sample of ever drinkers had engaged in 30 day binge drinking. Correlations among mediators were all statistically significant (range 0.16 – 0.47) and all were significantly associated with binge drinking. Statistically significant mediation was found for the association between ABM ownership and binge drinking through both drinker identity and having a favorite brand, which also mediated the path between movie brand exposure and binge drinking. Peer drinking and sensation seeking were associated with binge drinking in paths through all mediators. Conclusions Associations between alcohol marketing and binge drinking were mediated through marketing-specific cognitions that assess drinker identity and brand allegiance, cognitions that marketers aim to cultivate in the consumer.

Binge drinking during adolescence may perturb the maturing neuroenvironment and increase susceptibility of developing an alcohol use disorder later in life. In the present series of experiments, we utilized a modified version of the drinking in the dark-multiple scheduled access (DID-MSA) procedure to study how heavy binge drinking during adolescence alters responsivity to ethanol later in adulthood. Adult and adolescent C57BL/6J (B6) and DBA/2J (D2) males and females were given access to a 20% ethanol solution for 3 hourly periods, each separated by 2h of free water access. B6 adults and adolescents consumed 2 to 3.5 g/kg ethanol an hour and displayed significant intoxication and binge-like blood ethanol concentrations. There was an interaction of sex and age, however, driven by high intakes in adult B6 females, who peaked at 11.01 g/kg. Adolescents of both sexes and adult males never consumed more than 9.3 g/kg. D2 mice consumed negligible amounts of alcohol and showed no evidence of intoxication. B6 mice were abstinent for one month and were retested on the balance beam 10 min following 1.75 g/kg ethanol challenge (20%v/v; i.p). They were also tested for changes in home cage locomotion immediately following the 1.75 g/kg dose (for 10 min prior to balance beam). Although there was no effect of age of exposure, all mice with a binge drinking history demonstrated a significantly dampened ataxic response to an ethanol challenge. Female mice that binge drank during adulthood showed a significantly augmented locomotor response to ethanol when compared to their water drinking controls. This alteration was not noted for males or for females that binge drank during adolescence. These results highlight the importance of biological sex, and its interaction with age, in the development of behavioral adaptation following binge drinking.

An effort has been mounted to understand the mechanisms of alcohol dependence in a way that may allow for greater efficacy in treatment. It has long been suggested that drugs of abuse seize fundamental reward pathways and disrupt homeostasis to produce compulsive drug seeking behaviors. Ghrelin, an endogenous hormone that affects hunger state and release of growth hormone, has been shown to increase alcohol intake following administration, while antagonists decrease intake. Using rodent models of dependence, the current study examined the effects of two ghrelin receptor antagonists, [DLys3]-GHRP-6 (DLys) and JMV2959, on dependence-induced alcohol self-administration. In two experiments adult male C57BL/6J mice and Wistar rats were made dependent via intermittent ethanol vapor exposure. In another experiment, adult male C57BL/6J mice were made dependent using the intragastric alcohol consumption (IGAC) procedure. Ghrelin receptor antagonists were given prior to voluntary ethanol drinking. Ghrelin antagonists reduced ethanol intake, preference, and operant self-administration of ethanol and sucrose across these models, but did not decrease food consumption in mice. In experiments 1 and 2, voluntary drinking was reduced by ghrelin receptor antagonists, however this reduction did not persist across days. Despite the transient effects of ghrelin antagonists, the drugs had renewed effectiveness following a break in administration as seen in experiment 1. The results show the ghrelin system as a potential target for studies of alcohol abuse. Further research is needed to determine the central mechanisms of these drugs and their influence on addiction in order to design effective pharmacotherapies.

To test the assumption embedded in state-of-the-art, community assessment and decision-making regarding prevention of underage drinking: that there is minimal variation in the way that risk and protective factors (RPF) are associated with underage drinking across communities. Three large datasets provided the same measures of adolescent alcohol use and RPFs. Multilevel ordered-logistic regression models were carried out separately for each dataset and separately for males and females in 8th and 10th grades, testing random slopes for each RPF index. Predicted school-level coefficients were derived from these models, representing the association between RPFs and alcohol use. The variation in associations between RPFs and alcohol use across schools was greatest for antisocial peer risk and community protection; the lowest variation across schools was found for family cohesion and individual antisocial behavior. Ranges in predicted coefficients indicate large differences across schools for many RPFs. Bivariate correlations indicated that school-level associations vary across RPFs in expected directions. Policy makers should recognize that the magnitude of associations between RPFs and adolescent alcohol use vary considerably across communities, and that such variability is greater for certain RPFs than others. These findings have implications for policies regarding how prevention resources are targeted within and across communities.

Understanding the psychological mechanisms and underlying neurobiology of relapse behavior is essential for improving the treatment of addiction. Because the neurobiology of relapse behavior cannot be well studied in patients, we must rely on appropriate animal models. The alcohol deprivation effect (ADE) is a phenomenon in laboratory animals that models a relapse-like drinking situation, providing excellent face and predictive validity. In rodents, relapse-like behavior is largely influenced by the genetic make-up of an animal. It is not clear which other factors are responsible for variability of this behavior, but there seems to be no correlation between levels of baseline alcohol intake and the occurrence, duration, and robustness of the ADE. Rats that undergo long-term alcohol drinking for several months with repeated deprivation phases develop a compulsive drinking behavior during a relapse situation, characterized by insensitivity to taste adulteration with quinine, a loss of circadian drinking patterns during relapse-like drinking, and a shift toward drinking highly concentrated alcohol solutions to rapidly increase blood alcohol concentrations and achieve intoxication. Some mouse strains also exhibit an ADE, but this is usually of shorter duration than in rats. However, compulsive drinking in mice during a relapse situation has yet to be demonstrated. We extend our review section with original data showing that during long-term alcohol consumption, mice show a decline in alcohol intake, and the ADE fades with repeated deprivation phases. Furthermore, anti-relapse compounds that produce reliable effects on the ADE in rats produce paradoxical effects in mice. We conclude that the rat provides a better model system to study alcohol relapse and putative anti-relapse compounds.

Rationale While stress is often proposed to play a significant role in influencing alcohol consumption, the relationship between stress and alcohol is complex and poorly understood. Over several decades, stress effects on alcohol drinking have been studied using a variety of animal models and experimental procedures, yet this large body of literature has generally produced equivocal results. Objectives This paper reviews results from animal studies in which alcohol consumption is evaluated under conditions of acute/sub-chronic stress exposure or models of chronic stress exposure. Evidence also is presented indicating that chronic intermittent alcohol exposure serves as a stressor that consequently influences drinking. Results The effects of various acute/sub-chronic stress procedures on alcohol consumption have generally been mixed, but most study outcomes suggest either no effect or decreased alcohol consumption. In contrast, most studies indicate that chronic stress, especially when administered early in development, results in elevated drinking later in adulthood. Chronic alcohol exposure constitutes a potent stressor itself, and models of chronic intermittent alcohol exposure reliably produce escalation of voluntary alcohol consumption. Conclusions A complex and dynamic interplay among a wide array of genetic, biological, and environmental factors govern stress responses, regulation of alcohol drinking, and the circumstances in which stress modulates alcohol consumption. Suggestions for future directions and new approaches are presented that may aid in developing more sensitive and valid animal models that not only better mimic the clinical situation, but also provide greater understanding of mechanisms that underlie the complexity of stress effects on alcohol drinking.

Approximately 37% of college students report heavy episodic drinking (5 or more drinks in an occasion for men and 4 or more for women) in the past month. This pattern of drinking is often associated with high blood alcohol levels, accidents, injuries, and negative social and academic outcomes. There is a need for novel theoretical approaches to guide prevention efforts. Behavioral economics emphasizes the role of contextual determinants, such as drink price and the presence and amount of alternative reinforcement as determinants of drinking levels and has received strong empirical support in basic laboratory research. This translational research study used a hypothetical behavioral economic measure to investigate the impact of a variety of next-day responsibilities on night-before drinking intentions in a sample of first-year college students (N = 80; 50% female) who reported recent heavy episodic drinking. Drinking estimates were significantly lower in all of the responsibility conditions relative to the no-responsibility condition; internships were associated with the greatest reduction (d(rm) = 1.72), and earlier class times were associated with greater reductions in drinking intentions (d(rm) range = 1.22-1.35) than later class times (d(rm) range = 0.83-1.00). These results suggest that increasing morning responsibilities should be further investigated as a potential strategy to reduce drinking in college students.

Considerable basic and clinical research supports a behavioral economic conceptualization of alcohol and drug dependence. One behavioral economic approach to assess motivation for a drug is the use of demand curves, or quantitative representations of drug consumption and drug-reinforced responding across a range of prices. This study used a hypothetical alcohol purchase task to generate demand curves, and examined whether the resulting demand curve parameters predicted drinking outcomes following a brief intervention. Participants were 51 college student drinkers (67% female; 94% Caucasian; drinks/week: M=24.57, S.D.=8.77) who completed a brief alcohol intervention. Consistent with predictions, a number of demand curve indices significantly predicted post-intervention alcohol use and frequency of heavy drinking episodes, even after controlling for baseline drinking and other pertinent covariates. Most prominently, O(max) (i.e., maximum alcohol expenditure) and breakpoint (i.e., sensitivity of consumption to increasing price) predicted greater drinking at 6-month post-intervention follow-up. These results indicate that a behavioral economic measure of alcohol demand may have utility in characterizing the malleability of alcohol consumption. Moreover, these results support the utility of translating experimental assays of reinforcement into clinical research.

Underage drinking accounts for 4400 alcohol-attributable deaths in the US each year. After several reports of the deaths of young people due to the consumption of the flavored-alcoholic beverage (FAB) Four Loko, the Federal Trade Commission (FTC) examined whether Phusion Projects violated federal law by using deceptive marketing. In 2013, the FTC responded by ordering alcohol facts labels on Four Loko disclosing the number of standard drinks contained in the product. This paper aims to discuss whether the FTC's order for alcohol facts labels on Four Loko cans will effectively reduce the hazardous consumption of FABs among youth. The authors discuss the existing research that relates to the FTC's order, including studies on the effectiveness of serving size labeling for reducing youth drinking, research on the brand-specific consumption of FABs among underage youth, and the associations between youth drinking and exposure to alcohol marketing. After synthesizing the evidence, the authors conclude that simply requiring the disclosure of the number of standard drinks on supersized Four Loko cans is not likely to adequately address the hazardous consumption of this beverage among underage drinkers. Instead, if the FTC addresses the marketing of these products and its potential to encourage the excessive use of alcohol, as the Attorneys General did recently in a settlement with the same company, it is possible that there would be a greater impact on reducing youth alcohol consumption. Additional research is needed to determine the impact of alcohol facts labels in changing underage drinking behaviors.

Objective Alcohol expectancies are developed, in part, through exposure to health messages, the understanding of which may be influenced by health literacy. This study explores the relationships among health literacy, alcohol expectancies, and alcohol use behaviors in teens. Methods We studied alcohol use behaviors in the past six months in youths aged 14–19 recruited from two adolescent medicine clinics. We assessed covariate-adjusted bivariate relationships between HL, expectancies, and four measures of alcohol use and tested health literacy as a moderator of the relationship between expectancies and use. Results Of the 293 study teens, 45 percent reported use of alcohol in the past six months. Use behaviors were positively associated with higher health literacy and positive expectancies. Our moderation model suggested that health literacy moderates the relationship between expectancies and use, with the expectancy/use relationship being significantly stronger in higher literacy teens. Conclusion Findings suggest that health literacy can influence alcohol expectancies and behaviors. Practice implications: Health literacy should be explicitly considered in the design of alcohol prevention messages. PMID:25085549

The effects of a low dose of alcohol on car driving remain controversial. To address this issue, event-related potentials were recorded while subjects performed a simple car-following task in a driving simulator before and after consuming either "one drink" of beer (representing one standard alcoholic beverage containing 14 g of alcohol) or mineral water (control condition). Subjects who had consumed the determined amount of alcohol demonstrated no detectable outward behavioral signs of intoxication while performing the driving task, an observation in agreement with previous findings. However, the parietal P3 elicited by the brake lights of the preceding car was significantly reduced in amplitude, approximately 50% that observed under the control condition, likely indicating alteration of the neural processing of visual information critical for safe driving. The finding suggests that alcohol begins to affect neural processes for driving even at quantities too low to modify behavior.

Based on recent findings that post-retirement adjustment may be influenced by the conditions leading up to the decision to retire, we examine the impact of individual agency in the retirement decision on problematic drinking behavior, as well as the extent to which such an effect may itself depend upon the valence of the pre-retirement work experience. Using a sample of 304 blue-collar retirees, our findings indicate that, when controlling for pre-retirement drinking behavior, perceptions of retirement as the result of a more forced or involuntary decision are associated with greater alcohol consumption, while perceptions of retirement as the result of a more volitional or voluntary process are associated with lower levels of alcohol consumption and a lower risk of problematic drinking behavior. Our results also indicate that pre-retirement job satisfaction amplifies the former relationship, while attenuating the latter one. PMID:19956364

This study explores whether associations between consuming alcohol in bars and alcohol-related harms are consistent across countries and whether country-level characteristics modify associations. We hypothesized that genderedness of bar drinking modifies associations, such that odds of harms associated with bar drinking increase more rapidly in…

Alcohol use is a robust predictor of intimate partner violence (IPV). A critical barrier to progress in preventing alcohol-related IPV is that little is known about how an individual's specific drinking contexts (where, how often, and with whom one drinks) are related to IPV, or how these contexts are affected by environmental characteristics,…

This study explored effects of family, school, and marketing communications on alcohol use and intention to drink of Thai students. We conducted a survey in which 5,184 students participated. Respondents were selected randomly from school districts throughout Thailand. In this survey we measured the exposure to, reception of, and perceptions concerning alcohol marketing communication, school absenteeism and achievement, family alcohol use, students' alcohol use, and drinking intentions. Findings indicated students' low alcohol use, moderate intention to drink, and high prevalence of family drinking. The levels of exposure and also the information receptivity to alcohol media marketing of Thai students were low. The respondents had a high level of media literacy on alcohol marketing communication. Multiple regression and focus group discussions provided support for the contention that there were significant effects of school achievement, absenteeism and media marketing communication on alcohol use (R2 = 14%) and intention to drink (R2 = 11%). Therefore, consideration of relevant school and alcohol policies, including monitoring of media marketing communication, will be needed.

It has been suggested that consuming alcohol mixed with energy drink (AMED) may increase total alcohol consumption. Aims of this systematic review and meta-analysis were (i) to compare alcohol consumption of AMED consumers with alcohol only (AO) consumers (between-group comparisons), and (ii) to examine if alcohol consumption of AMED consumers differs on AMED and AO occasions (within-subject comparisons). A literature search identified fourteen studies. Meta-analyses of between-group comparisons of N = 5212 AMED consumers and N = 12,568 AO consumers revealed that on a typical single drinking episode AMED consumers drink significantly more alcohol than AO consumers (p = 0.0001, ES = 0.536, 95%CI: 0.349 to 0.724). Meta-analyses of within-subject comparisons among N = 2871 AMED consumers revealed no significant difference in overall alcohol consumption on a typical drinking episode between AMED and AO occasions (p = 0.465, ES = -0.052, 95%CI: -0.192 to 0.088). In conclusion, between-group comparisons suggest that heavy alcohol consumption is one of the several phenotypical differences between AMED and AO consumers. Within-subject comparisons revealed, however, that AMED consumption does not increase the total amount of alcohol consumed on a single drinking episode.

Objective Alcohol use and its associated behaviors are among the most common reasons for medical treatment and disciplinary infractions among college students. The purpose of this study was to describe the characteristics of students who had recent serious alcohol-related incidents and to identify predictors of motivation to change alcohol use and heavy drinking in particular, with specific attention to gender. Method Students (N = 227; 52% female) who had been mandated to attend a session of alcohol education following alcohol-related medical treatment and/or a disciplinary infraction were assessed on their alcohol use, alcohol problems, characteristics of their alcohol-related incident, reactions to the incident, attributions about the incident, and motivation to change drinking and heavy drinking. Path and regression analyses were used to identify the individual and incident-related characteristics that were related to motivation to change. Results Perceived aversiveness of the incident was directly and positively related to motivation to change drinking and heavy drinking. Alcohol consumption in the month before the incident and past-year alcohol problems were negatively related to motivation to change heavy drinking, and women were more motivated to change heavy drinking than men. The more students consumed in the incident, the more likely they were to feel responsible for it, and the more responsible they felt about the incident, the greater its aversiveness. Conclusions Individual and incident-related characteristics are both directly and indirectly associated with motivation to change following an alcohol-related incident, and therefore have implications for interventions with college drinkers who have experienced an alcohol-related incident.

The consumption of alcohol mixed with energy drinks (AmED) has become a popular and controversial practice among young people. Increased rates of impaired driving and injuries have been associated with AmED consumption. The purpose of this study was to examine if the consumption of AmED alters cognitive processing and subjective measures of intoxication compared with the consumption of alcohol alone. Eighteen participants (9 men and 9 women) attended 4 test sessions where they received one of 4 doses in random order (0.65 g/kg alcohol, 3.57 ml/kg energy drink, AmED, or a placebo beverage). Performance on a psychological refractory period (PRP) task was used to measure dual-task information processing and performance on the Purdue pegboard task was used to measure simple and complex motor coordination following dose administration. In addition, various subjective measures of stimulation, sedation, impairment, and level of intoxication were recorded. The results indicated that alcohol slowed dual-task information processing and impaired simple and complex motor coordination. The co-administration of the energy drink with alcohol did not alter the alcohol-induced impairment on these objective measures. For subjective effects, alcohol increases various ratings indicative of feelings of intoxication. More importantly, co-administration of the energy drink with alcohol reduced perceptions of mental fatigue and enhanced feelings of stimulation compared to alcohol alone. In conclusion, AmED may contribute to a high-risk scenario for a drinker. The mix of behavioral impairment with reduced fatigue and enhanced stimulation may lead AmED consumers to erroneously perceive themselves better able to function than is actually the case.

Previous research reported positive associations between alcohol mixed with energy drink (AMED) consumption and overall alcohol consumption. However, results were largely based on between-subjects comparisons comparing AMED consumers with alcohol-only (AO) consumers, and therefore cannot sufficiently control for differences in personal characteristics between these groups. In order to determine whether AMED consumers drink more alcohol on occasions they consume AMED compared to those when they drink AO additional within-subjects comparisons are required. Therefore, this UK student survey assessed both alcohol consumption and alcohol-related negative consequences when consumed alone and when mixed with energy drinks, using a within-subject design. A total of 1873 students completed the survey, including 732 who consumed AMED. It was found that AMED consumers drank significantly less alcohol when they consumed AMED compared to when they drank AO (p < 0.001). In line with reduced alcohol consumption significantly fewer negative alcohol-related consequences were reported on AMED occasions compared to AO occasions (p < 0.001). These findings suggest that mixing alcohol with energy drinks does not increase total alcohol consumption or alcohol-related negative consequences.

Heightened emotional states increase impulsive behaviors such as excessive ethanol consumption in humans. Though positive and negative affective states in rodents can be monitored in real-time through ultrasonic vocalization (USV) emissions, few animal studies have focused on the role of emotional status as a stimulus for initial ethanol drinking. Our laboratory has recently developed reliable, high-speed analysis techniques to compile USV data during multiple-hour drinking sessions. Since High Alcohol Drinking (HAD-1) rats are selectively bred to voluntarily consume intoxicating levels of alcohol, we hypothesized that USVs emitted by HAD-1 rats would reveal unique emotional phenotypes predictive of alcohol intake and sensitive to alcohol experience. In this study, male HAD-1 rats had access to water, 15% and 30% EtOH or water only (i.e., Controls) during 8 weeks of daily 7-h drinking-in-the-dark (DID) sessions. USVs, associated with both positive (i.e., 50-55 kHz frequency-modulated or FM) and negative (i.e., 22-28 kHz) emotional states, emitted during these daily DID sessions were examined. Findings showed basal 22-28 kHz USVs were emitted by both EtOH-Naïve (Control) and EtOH-experienced rats, alcohol experience enhanced 22-28 kHz USV emissions, and USV acoustic parameters (i.e., mean frequency in kHz) of both positive and negative USVs were significantly suppressed by chronic alcohol experience. These data suggest that negative affective status initiates and maintains excessive alcohol intake in selectively bred HAD-1 rats and support the notion that unprovoked emissions of negative affect-associated USVs (i.e., 22-28 kHz) predict vulnerability to excessive alcohol intake in distinct rodent models.

Binge drinking is associated with many health and financial costs and is linked to risks of legal consequences. As alcohol use typically is initiated during adolescence, the current study assessed the relationship between parental behaviors and strategies in forecasting adolescents' likelihood of binge drinking and later arrest. Restricted data from waves I-IV of the National Longitudinal Study of Adolescent Health were used to assess hypotheses. A weighted path analytic model (N = 9421) provided a multifaceted picture of variables linked to later antisocial behavior. Low parental monitoring, low parental warmth, parent alcohol use, and parent expectancies regarding their children's alcohol use were associated with higher incidence of adolescent binge drinking. In turn, low monitoring, low warmth, parent alcohol use, parent expectancies, and underage consumption were associated with binge drinking in early adulthood. Binge drinking during both adolescence and young adulthood were predictive of respondents' likelihood of arrest 8-14 years later. Findings demonstrated the substantial, enduring effects of parental behaviors on child alcohol-related actions and have implications for parent-targeted interventions designed to reduce excessive alcohol consumption. They suggest campaigns focus on parenting strategies that involve setting effective and strict alcohol-related rules and guidelines, while maintaining a warm and supportive family environment.
College binge drinking is examined from the perspectives of two cultures. The traditional culture views binging as deviant; the second culture promotes it. In this context, logit regression is used to explore the effects of various factors, including student employment and parental education. Employed students are less likely to binge than are students who are not employed. Also, students whose mother is a college graduate, but whose father is not, are more likely to binge than other students. The prescriptions for reducing binge drinking are different when the behavior is perceived as mainstream rather than deviant. The research calls for the development of a process for promoting cultural change in an environment of continually changing student leadership.

Binge drinking (five drinks or more in a 2-h sitting for men or four or more drinks in a 2-h sitting for women) and alcohol-related problems are a growing problem among Asian American young adults. The current study examines the sociocultural (i.e., generational status and ethnic identity) determinants of binge drinking and alcohol-related problems across U.S.-born, young-adult, Asian American ethnic groups. Data were collected from 1,575 Asian American undergraduates from a public university in Southern California. Chinese Americans consisted of the largest Asian ethnicity in the study, followed by Vietnamese, Filipino, Korean, South Asian, Japanese, Multi-Asian, and "other Asian American." Participants completed a web-based assessment of binge drinking, alcohol-related problems, ethnic identity, descriptive norms (i.e., perceived peer drinking norms), and demographic information. An analysis of variance was used to determine potential gender and ethnic differences in binge drinking and alcohol-related problems. Negative binomial regression was selected to examine the relationship between the predictors and outcomes in our model. There were no gender differences between Asian American men and women in regards to binge drinking; however, men reported more alcohol-related problems. Japanese Americans reported the highest number of binge-drinking episodes and alcohol-related problems, followed by Filipino and Multi-Asian Americans (e.g., Chinese and Korean). Living off-campus; higher scores in descriptive norms; Greek status; and belonging to the ethnic groups Japanese, Filipino, Multi-Asian, Korean, and South Asian increased the risk of engaging in binge drinking. Quantity of alcohol consumed, Greek status, gender, Filipino, South Asian, other Asian, and lower ethnic identity scores were related to alcohol-related problems. Using one of the largest samples collected to date on sociocultural determinants and drinking among U.S.-born Asian American young adults, the

Chronically homeless individuals with alcohol dependence experience severe alcohol-related consequences. It is therefore important to identify factors that might be associated with reduced alcohol-related harm, such as the use of safer-drinking strategies. Whereas effectiveness of safer-drinking strategies has been well-documented among young adults, no studies have explored this topic among more severely affected populations, such as chronically homeless individuals with alcohol dependence. The aims of this study were thus to qualitatively and quantitatively document safer-drinking strategies used in this population. Participants (N=31) were currently or formerly chronically homeless individuals with alcohol dependence participating in a pilot study of extended-release naltrexone and harm-reduction counseling. At weeks 0 and 8, research staff provided a list of safer-drinking strategies for participants to endorse. Implementation of endorsed safer-drinking strategies was recorded at the next appointment. At both time points, strategies to buffer the effects of alcohol on the body (e.g., eating prior to and during drinking) were most highly endorsed, followed by changing the manner in which one drinks (e.g., spacing drinks), and reducing alcohol consumption. Quantitative analyses indicated that all participants endorsed safer-drinking strategies, and nearly all strategies were implemented (80-90% at weeks 0 and 8, respectively). These preliminary findings indicate that chronically homeless people with alcohol dependence use strategies to reduce harm associated with their drinking. Larger randomized controlled trials are needed to test whether interventions that teach safer-drinking strategies may reduce overall alcohol-related harm in this population.

Objectives Transdermal alcohol monitoring is used extensively in forensic settings to identify whether individuals have violated court-ordered mandates to abstain from drinking. Despite widespread use in that setting, comparatively few studies have explored the clinical utility of transdermal alcohol monitoring. Furthermore, of the few studies conducted, most have relied on the forensically established conservative criteria to identify whether or not a drinking episode has occurred. Here, we explore how transdermal alcohol monitoring data can be used to estimate more clinically meaningful parameters relevant to clinical treatment programs. Methods We developed a procedure to use transdermal data to objectively estimate the number of standardized drinks an individual has consumed. Participants included 46 men and women who consumed 1 to 5 beers within 2 hours in the laboratory on separate days while wearing devices to monitor transdermal alcohol concentrations (TAC). Results A mathematical model was derived to estimate the number of standardized alcohol drinks consumed, which included a number of variables (time-to-peak TAC, area under the TAC curve, and sex). The model was then validated by applying it to data from a separate study. Our results indicate that transdermal alcohol devices can be used to estimate the number of standard drinks consumed. Conclusions Objective methods characterizing both the level of intoxication achieved and the number of drinks consumed, such as transdermal alcohol monitoring, could be useful in both research and treatment settings.

Oral infections have been associated with an increased risk for myocardial infarction (MI) and other cardiovascular diseases (CVD). Conversely, low, regular alcohol consumption is associated with a lower association of CVD. The objective was to test the novel hypothesis that oral infections are modified by regular alcohol drinking which has the effect of lowering the incidence of MI's. The effect has been observed where tooth extractions where carried out due to infections and compared with extractions unconnected to infections. Oral infections and in particular periodontal infections impose an infectious load on the health in many people. In its advanced forms (periodontal pockets ≥ 6mm) periodontitis affects ∼10-15% of adults. The infection runs a chronic course with exacerbations. The bacteria cause local infection destructive to the supporting tissues of the teeth and have been detected in systemic diseases through bacterial products and bacteria entering the circulation. The often persistent, long term history of chronic periodontal infection in individuals is a challenge to the immune system. Over 700 oral bacteria and other microorganisms have been identified, many of which are virulent. Control of the level of oral microbiota is through well known oral hygiene measures. Alcohol by being bactericidal is a factor that may reduce the bacterial level in the oral cavity. If this effect truly exists, it should be observed through reduction of infections in the mouth. Tooth extraction is the ultimate consequence of periodontal and dental infections and a reduction of tooth extraction due to infections should therefore be observed. The hypothesis was tested using the screening data of the Oslo II-study in a cross sectional analysis. The Oslo-study included men aged 48-67 years. The main finding was that the effect of a drinking pattern of 2-7 times per week reduced the risk of MI among men who had a history of tooth extractions due to infections versus tooth

Social anxiety disorder more than quadruples the risk of developing an alcohol use disorder, yet it is inconsistently linked to drinking frequency. Inconsistent findings may be at least partially due to lack of attention to drinking context - it may be that socially anxious individuals are especially vulnerable to drinking more often in specific contexts that increase their risk for alcohol-related problems. For instance, socially anxious persons may drink more often while alone, before social situations for "liquid courage" and/or after social situations to manage negative thoughts about their performance. Among current (past-month) drinkers (N=776), social anxiety was significantly, positively related to solitary drinking frequency and was negatively related to social drinking frequency. Social anxiety was indirectly (via solitary drinking frequency) related to greater past-month drinking frequency and more drinking-related problems. Social anxiety was also indirectly (via social drinking frequency) negatively related to past-month drinking frequency and drinking-related problems. Findings suggest that socially anxious persons may be vulnerable to more frequent drinking in particular contexts (in this case alone) and that this context-specific drinking may play an important role in drinking problems among these high-risk individuals.

Social norms are sustained and disseminated, both implicitly and explicitly, through the act of communication. As a result, communication researchers have sought to classify and target normative perceptions to enact social change. In line with this research, the current study investigated whether perceptions of past normative behavior, referred to here as historical norms, were significantly related to current behavior. Using the theory of normative behavior as a guiding framework, two studies were conducted to assess whether college student drinking behavior was related to one of two perceived historical drinking norms measures: historical consumption norms (i.e., the perceived percentage of students who drank over time) and historical tradition norms (i.e., the perception of drinking as a university tradition). Study 1 revealed that although historical consumption norms was not directly related to drinking behavior, it moderated the effect of descriptive norms on drinking behavior (p = .03). A full assessment of the theory of normative social behavior was conducted in study 2 to determine whether perceived historical drinking norms influenced behavior above and beyond both descriptive and injunctive norms. Findings demonstrated that historical tradition norms were significantly related to drinking behavior (p = .001), and marginally moderated the relationship between descriptive norms and drinking behavior (p = .09). These findings offer preliminary evidence in support of measuring perceived historical drinking norms in future campaigns and interventions designed to reduce drinking behavior.

Social norms are key predictors of college student drinking. Additionally, the social reasons for consumption (i.e. social drinking motives) are important to understanding drinking behaviour. This study investigated the effects of social norms and social motives on alcohol consumption. A total of 229 college students completed an online questionnaire assessing their drinking behaviour, social drinking motives and their perceived drinking social norms. Drinking social norms were assessed as descriptive norms (i.e. the individual's perceived prevalence of alcohol consumption), and injunctive norms (i.e. the individual's perceived approval of drinking by their peers). Additionally, injunctive norms were further separated into distal (socially distant peers) and proximal (socially close peers). Hierarchical regression analyses revealed descriptive norms, proximal injunctive norms and social motives all independently predicted alcohol consumption. Additionally, the relationship between proximal injunctive norms and consumption, and descriptive norms and consumption was mediated by social motives. Lastly, there was a significant three-way interaction between descriptive norms, distal injunctive norms and social motives on drinking. Consideration of both the individual factors and the complex interplay between social norms and social motives on alcohol consumption is necessary to further understand drinking behaviour, and to develop more effective alcohol harm-reduction strategies.

Alcohol consumption is associated with sexual behavior and outcomes, though research indicates a variety of moderating factors, including demographic characteristics. To better target interventions aimed at alcohol-related sexual risk behavior, our analyses simultaneously examine demographic predictors of both day- and event-level associations between alcohol consumption and sexual behavior in a sample of young adults (N = 301) who are sexually active and consume alcohol. Young adults (aged 18-29) recruited using time-space sampling and incentivized snowball sampling completed a survey and a timeline follow-back calendar reporting alcohol consumption and sexual behavior in the past 30 days. On a given day, a greater number of drinks consumed was associated with higher likelihood of sex occurring, particularly for women and single participants. During a given sexual event, number of drinks consumed was not associated with condom use, nor did any demographic predictors predict that association. Findings highlight associations between alcohol and sexual behavior, though not between alcohol and sexual risk behavior, highlighting the need for additional research exploring the complex role of alcohol in sexual risk behavior and the need to develop prevention efforts to minimize the role of alcohol in the initiation of sexual encounters.

We previously reported that high-alcohol-drinking (HAD) rats exhibited selective deficits in active avoidance learning and that those deficits were partially reversed by moderate doses of ethanol under certain training conditions [Pharmacol. Biochem. Behav. 75 (2003) 89]. In that study, we hypothesized that HAD deficits resulted from exaggerated fear in the conditioning context and that the anxiolytic properties of ethanol, along with prior exposure to the conditioning apparatus, were responsible for the facilitated avoidance learning that was observed in HAD rats following moderate doses of ethanol. The current study was designed to test whether HAD rats exhibit behaviors consistent with increased fear in aversive learning contexts. We used a standard Pavlovian fear conditioning paradigm to assess behavioral freezing in HAD (HAD-1 and HAD-2) and low-alcohol-drinking (LAD; LAD-1 and LAD-2) rats. No significant differences were observed between HAD-1 and HAD-2 or between LAD-1 and LAD-2 rats, indicating that the replicate lines performed similarly in this study. Both HAD and LAD rats exhibited robust fear conditioning during training. Although no differences were observed between HAD and LAD rats during fear training, HAD rats failed to extinguish freezing behavior in response to the discrete tone conditional stimulus during subsequent fear retention tests. Thus, HAD rats demonstrated prolonged cue-elicited fear that was resistant to extinction.

Background This paper examines age at first drink and adult drinking, binge drinking and DSM-5 alcohol use disorder (AUD) among U.S. Hispanic national groups. Methods Respondents come from two independent studies. The Hispanic Americans Baseline Alcohol Survey used a multistage cluster sample design to interview 5,224 individuals 18 years of age and older selected from the household population in: Miami, New York, Philadelphia, Houston and Los Angeles. Respondents in the border area (N=1,307) constituted a household probability sample of Mexican Americans living on U.S. counties that border Mexico. In both surveys, data were collected during computer assisted interviews conducted in respondents' homes. The HABLAS and the border sample response rates were 76% and 67%, respectively. Results U.S. born Hispanics begin drinking at a younger age than those who are foreign born, independent of national group. Among foreign born Hispanics, age of arrival in the U.S. is not associated with age at first drink. Results support the hypothesis that a younger age at first drink is associated with a higher mean volume of drinking, a higher probability of bingeing and a higher probability of DSM-5 AUD. But the results do not show a clear pattern by which a particular national group would consistently show no associations or stronger associations between age at first drink and the alcohol-related outcomes under consideration. Conclusions An earlier age at first drinking is positively associated with heavier drinking patterns among U.S. Hispanics. However, as in other areas of alcohol epidemiology, here too there is considerable variation in age at first drink and drinking across Hispanic national groups. PMID:24689445

Students report drinking for social reasons, yet the social benefits of alcohol use are less understood. Associations between social drinking motives, drinking behaviors, and college friendships were examined via in-person interviews with 72 college freshmen from a large Midwestern University. Social drinking motives were significantly associated with drinking behaviors; however, drinking behaviors were not associated with the number of new casual or close friends students made at college. Consistent with previous research, social motives predicted drinking behaviors; however drinking behaviors were unrelated to friendship outcomes. Drinking prevention campaigns might incorporate these findings in an effort to alter college freshmen’s social alcohol expectancies. PMID:24634551

Objective Electronic Music Dance Events (EMDEs) in nightclubs are settings where young adults tend to engage in high risk behaviors, such as heavy alcohol/drug use. Consequences of these behaviors may be prevented if young adults engaged in protective strategies with their drinking group. It is important to identify drinking group characteristics that predict willingness to intervene with peers. Objectives are to: 1) examine whether young adults at EMDEs would be willing to intervene with members of their drinking group; and 2) identify both individual and group characteristics of drinking groups that predict willingness to intervene. Method Nightclub patrons (N=215 individuals; 80 groups) were surveyed anonymously as they entered clubs. Individual and group-level characteristics were measured in relation to willingness to intervene with peers. Mixed model regressions were conducted, accounting for nesting by drinking group. Results : Analyses show that participants were willing to intervene with their peers. Groups that knew each other well and had lower expectations for members’ drinking were more willing to intervene. Women, younger and older participants were also more willing to intervene. Conclusions Findings show that club patrons are willing to intervene with their drinking groups to protect them from harmful consequences of heavy drinking and drug use. Findings indicate characteristics of both individuals and drinking groups that could be targeted in interventions among young adults largely not being reached by college interventions. PMID:26999349

This study investigated the relative contribution of the Big 5 personality factors and alcohol metacognitions in predicting weekly levels of alcohol use in binge drinking university students. No research to date has investigated whether either of these constructs predicts levels of weekly alcohol use in binge drinkers. A sample of university students (n=142) who were classified as binge drinkers were administered the following self-report instruments: NEO-Five Factor Inventory (NEO-FFI; Costa & McCrae, 1992), Positive Alcohol Metacognitions Scale (PAMS; Spada & Wells, 2008), Negative Alcohol Metacognitions Scale (NAMS; Spada & Wells, 2008), and Khavari Alcohol Test (KAT; Khavari & Farber, 1978). Pearson product-moment correlations showed that weekly levels of alcohol use were negatively correlated with agreeableness and conscientiousness and positively correlated with positive alcohol metacognitions about cognitive self-regulation, negative alcohol metacognitions about uncontrollability and negative alcohol metacognitions about cognitive harm. A hierarchical regression analysis revealed that conscientiousness and positive alcohol metacognitions about cognitive self-regulation were the only two significant predictors of weekly levels of alcohol use when controlling for gender. These findings show that being male, low on conscientiousness and high on positive alcohol metacognitions about cognitive self-regulation raises the risk for increased weekly levels of alcohol use in binge drinking university students. The implications of these findings are discussed.

The unique and interactive effects of paternal and maternal alcohol problems on the drinking behavior of adolescent girls and boys were investigated. A prospective design was employed to examine changes in youth drinking behavior over a 3-year period in a community-based sample of 695 families. Results revealed that, as maternal alcohol problems increased, the likelihood of adolescent alcohol use increased. Paternal alcohol problems were associated with an increased likelihood of alcohol use for girls only. Findings point to the need for future research to investigate both maternal and paternal alcohol problems in community samples and with a sample size large enough to examine both parent and adolescent gender. Implications for preventive and interventive efforts are considered.

Considering that current trends in sexual behavior and alcohol use among adolescents pose a significant public health risk, more research is needed in this area. Using a cross-sectional design, this study examined sex and alcohol behaviors among middle school and high school students in southeastern North Carolina. The findings suggested that there were strong associations between overall drinking patterns and sexual behaviors. Further analyses examined the effect of several demographic and behavioral factors on sexual experience and condom use for both middle and high school students. Alcohol, race, and age were significant determinants of sexual experience for all students while gender was significant for middle school students. None of the measured factors, including AIDS education, significantly increased condom use among sexually active students. The results suggested that sexuality and alcohol education methods and content should be re-evaluated and should begin in or before middle school.

The aim of this study was to investigate to what extent alcohol-specific parenting practices relate to adolescents' alcohol use, binge drinking, and alcohol-related problems, and whether these associations are moderated by socioeconomic status (SES), i.e. parents' education level and family income. The present data were collected within the framework of a representative study on alcohol use among Dutch students. The present findings are based on data from respondents who had been drinking in the past year (81.5%), and of whom one of the parents had filled out a short questionnaire including SES characteristics (52%). The sample consisted of 1,344 adolescents. Adolescents were approached in a school setting; parents received a short questionnaire at the home address. The results show that applying strict rules about alcohol use and having qualitative good conversations about drinking alcohol seem to prevent adolescents from heavy drinking patterns, whereas parental alcohol use seems to promote adolescents' drinking. A positive association was found between frequency of alcohol communication and availability of alcohol at home on the one hand and adolescents' drinking on the other. Some moderating effects of SES were found.

The rise in marketing and mass consumption of energy drink products by adolescents poses a largely unknown risk on adolescent development and drug reward. Yet, with increasing reports of acute health issues present in young adults who ingest large quantities of energy drinks alone or in combination with alcohol, the need to elucidate these potential risks is pressing. Energy drinks contain high levels of caffeine and sucrose; therefore, exposure to energy drinks may lead to changes in drug-related behaviors since caffeine and sucrose consumption activates similar brain pathways engaged by substances of abuse. With a recent study observing that adolescent caffeine consumption increased cocaine sensitivity, we sought to investigate how prolonged energy drink exposure in adolescence alters alcohol use and preference in adulthood. To do so, we utilized three different energy drink exposure paradigms and two strains of male mice (C57BL/6 and BALB/c) to monitor the effect of caffeine exposure via energy drinks in adolescence on adult alcohol intake. These paradigms included two models of volitional consumption of energy drinks or energy drink-like substances and one model of forced consumption of sucrose solutions with different caffeine concentrations. Following adolescent exposure to these solutions, alcohol intake was monitored in a limited-access, two-bottle choice between water and increasing concentrations of alcohol during adulthood. In none of the three models or two strains of mice did we observe that adolescent 'energy drink' consumption or exposure was correlated with changes in adult alcohol intake or preference. While our current preclinical results suggest that exposure to large amounts of caffeine does not alter future alcohol intake, differences in caffeine metabolism between mice and humans need to be considered before translating these results to humans.

Despite efforts to limit underage access to alcohol, alcohol availability remains a challenge for youth drinking prevention. This paper fills a gap in our understanding of alcohol consumption among youths by systematically investigating how and under what circumstances they obtain alcohol and the context within which they consume it. Qualitative interviews (n=47) were conducted with teens to collect information about where and how they obtain alcohol and the contexts within which they drink. Respondents were knowledgeable about commercial and social sources and used this knowledge in their decision making regarding where to obtain alcohol. Teens used their social relationships to circumvent existing policies designed to limit underage access to alcohol. Findings indicate that the majority of teens’ drinking occasions occur in their own or someone else’s home. PMID:25445811

Making appropriate recommendations for safe drinking behavior among different age groups requires understanding of differences between young and older adults in following them. The purpose of this study was to investigate how drinking behavior in terms of drinking speed and bolus size differs between young and older adults following instructions to change drinking rate. Thirty young (mean age 24.7 years) and 30 older (mean age 66.9 years) healthy female participants were recruited. All participants drank water under different drinking instructions: "as they normally would", "as quickly as is comfortably possible", and "slowly". Results showed that when asked to drink quickly, both age groups increased drinking speed to a similar extent. When asked to drink slowly, older adults were unable to slow their drinking rate as much as young adults (P < .001). When drinking slowly, older adults had significantly larger bolus size than young adults'. These suggest that in a healthcare setting, the often prescribed advice to "drinking slowly" may be insufficient precaution for older patients. Prudence is suggested to carefully observe patients drinking after they've been asked to drink slowly, before making a clinical judgment if additional, more specific strategies may be indicated.

This paper focuses on the contemporary British moral panic about young people and the consumption of alcohol in public space. Most of this public debate has focused on binge drinking in urban areas as a social problem. Here, we consider instead the role of alcohol in rural communities, and in particular alcohol consumption in domestic and informal…

Objective To quantify James Bond’s consumption of alcohol as detailed in the series of novels by Ian Fleming. Design Retrospective literature review. Setting The study authors’ homes, in a comfy chair. Participants Commander James Bond, 007; Mr Ian Lancaster Fleming. Main outcome measures Weekly alcohol consumption by Commander Bond. Methods All 14 James Bond books were read by two of the authors. Contemporaneous notes were taken detailing every alcoholic drink taken. Predefined alcohol unit levels were used to calculate consumption. Days when Bond was unable to consume alcohol (such as through incarceration) were noted. Results After exclusion of days when Bond was unable to drink, his weekly alcohol consumption was 92 units a week, over four times the recommended amount. His maximum daily consumption was 49.8 units. He had only 12.5 alcohol free days out of 87.5 days on which he was able to drink. Conclusions James Bond’s level of alcohol intake puts him at high risk of multiple alcohol related diseases and an early death. The level of functioning as displayed in the books is inconsistent with the physical, mental, and indeed sexual functioning expected from someone drinking this much alcohol. We advise an immediate referral for further assessment and treatment, a reduction in alcohol consumption to safe levels, and suspect that the famous catchphrase “shaken, not stirred” could be because of alcohol induced tremor affecting his hands.

Numerous studies have highlighted that personality traits are associated with alcohol problems and disorders; however, little is known on the link between personality and the quantities of alcohol actually ingested during given drinking episodes (i.e. in situ alcohol consumption, in grams of pure alcohol). Based on data of 123 young adults who participated in two wine-tasting assignments (one performed in group, the other individually; sequence of participation assigned at random), the results from regression models suggest that individual characteristics and personality traits are, to some extent, associated with in situ alcohol consumption, but contextual factors (e.g., in line with behavioral exposition and perceptions of norms) might overwhelm such associations in a social context, or later on in similar drinking contexts. These findings argue for the development of early preventive initiatives focusing on social influences and on specific drinking context.

Research suggests that workplace harassment (WH) significantly predicts alcohol use and problem drinking behavior, but has generally failed to consider concurrent effects of other sources of stress. This two-wave study (n=1418) is the first to explore whether sexual harassment (SH) and generalized workplace harassment (GWH) predict increased drinking independently of the effects of job and life stress, and whether effects differ by gender, in a nationally representative sample. SH and GWH predicted increases in problem drinking one year later for men but not women, while life stress was associated with increased problem drinking for women but not men. This study confirms the importance of examining the associations between different types of stressors and drinking-related outcomes in gendered contexts. PMID:18384975

Objectives To assess whether exposure to alcohol use in films (AUF) is associated with alcohol use susceptibility, current alcohol use, and binge drinking in adolescents from two Latin American countries. Methods Cross-sectional study with 13,295 middle school students from public and private schools in Mexico and Argentina. Exposure to alcohol use in over 400 contemporary top box office films in each country was estimated using previously validated methods. Outcome measures included current drinking (i.e., any drink in the last 30 days), ever binge-drinking (i.e., more than 4 or 5 drinks in a row for females and males, respectively) and, among never drinkers, alcohol susceptibility (i.e., might drink in the next year or accept a drink from a friend). Multivariate models were adjusted for age, sex, parental education, peer drinking, sensation seeking, parenting style and media access. Results Mean age was 12.5 years (SD = 0.7) and the prevalence of alcohol consumption and binge drinking was 19.8% and 10.9% respectively. Mean exposure to alcohol from the film sample was about 7 hours in both countries. Adjusted models indicated independent dose-response associations between higher levels of exposure to AUF and all outcomes; the adjusted odds ratios (OR) comparing quartiles 4 and 1 1.99 (95% CI 1.73 - 2.30) for current drinking, 1.68 (1.39 - 2.02) for binge drinking, and 1.80 (1.52 - 2.12) for alcohol susceptibility. Compared to Mexican adolescents, Argentine adolescents were significantly more likely to have engaged in binge drinking (OR 1.40, 95% CI 1.12 - 1.76.) and, among never drinkers, were more susceptible to trying drinking (OR 1.40, 95% CI 1.20 - 1.64). Conclusions Higher levels of exposure to alcohol use in films was associated with higher likelihood of alcohol use, binge drinking, and alcohol susceptibility in Latin American adolescents.

Alcohol consumption is a potential risk factor for being overweight. We aimed to investigate the effects of an alcohol priming dose and an alcohol-related environment on snacking behaviour. One hundred and fourteen social drinkers completed one of four experimental sessions either receiving a priming dose of alcohol (.6 g/kg) or soft drink in a bar-lab or a sterile lab. Participants provided ratings of appetite, snack urge, and alcohol urge before and after consuming their drinks. Participants completed an ad libitum snack taste test of savoury and sweet, healthy and unhealthy foods before completing the self-reports a final time. Appetite and snack urge increased more following alcohol consumption, and decreased to a lesser extent following the taste test relative to the soft drink. Total calories (including drink calories) consumed were significantly higher in the alcohol groups. There was a marginal effect of environment; those in the bar-lab consumed a higher proportion of unhealthy foods. These effects were more pronounced in those who were disinhibited. While alcohol may not increase food consumption per se, alcohol may acutely disrupt appetite signals, perhaps via processes of reward and inhibitory control, resulting in overall greater calorie intake. Individuals who are generally disinhibited may be more vulnerable to the effects of alcohol and drinking environments on eating behaviour.

Gray's (1975, 1987) behavioral activation (BAS) and behavioral inhibition systems (BIS) are thought to underlie sensitivity to reinforcement and punishment, respectively. Consistent with Gray's theory and the Acquired Preparedness model, BAS may facilitate the learning of positive alcohol expectancies (PAEs) over time, leading to increases in drinking. Yet, no prospective tests of this pathway have been reported. The present study investigated whether BAS prospectively predicted PAEs and whether PAEs mediated the association between BAS and subsequent alcohol use. We hypothesized that BAS would influence drinking specifically via enhancement-related PAEs. We also explored the role of BIS in PAEs and drinking. College students (N=557) completed online BAS, PAE, and alcohol use measures in September of their first (T1), second (T2), and third (T3) years of college. We conducted autoregressive path analyses with three BAS subscales and BIS (T1) as predictors, four PAE types (T2) as mediators, and quantity and frequency of drinking (T3) as outcomes. The BAS Fun-Seeking scale was prospectively associated with PAEs, and there was a significant indirect path from Fun-Seeking to alcohol use mediated specifically through activity enhancement PAEs. BIS was positively associated with some PAE types, but did not have indirect effects on drinking. Findings are consistent with both the theory of the BAS and the Acquired Preparedness model, as individuals high on BAS Fun-Seeking may find the rewarding properties of alcohol more reinforcing, leading to stronger enhancement PAEs and increased drinking over time. The prospective design helps establish the temporal association between BAS and alcohol-related learning, and points to the need for prevention efforts that target these at-risk students.
The DSM-5 has created significant changes in the definition of alcohol use disorders (AUD). Limited work has considered the impact of these changes in specific populations, such as heavy-drinking college students. Latent class analysis (LCA) is a person-centered approach that divides a population into mutually exclusive and exhaustive latent classes, based on observable indicator variables. The present research was designed to examine whether there were distinct classes of heavy-drinking college students who met DSM-5 criteria for an AUD and whether gender, perceived social norms, use of protective behavioral strategies (PBS), drinking refusal self-efficacy (DRSE), self-perceptions of drinking identity, psychological distress, and membership in a fraternity/sorority would be associated with class membership. Three-hundred and ninety-four college students who met DSM-5 criteria for an AUD were recruited from three different universities. Two distinct classes emerged: Less Severe (86%), the majority of whom endorsed both drinking more than intended and tolerance, as well as met criteria for a mild AUD; and More Severe (14%), the majority of whom endorsed at least half of the DSM-5 AUD criteria and met criteria for a severe AUD. Relative to the Less Severe class, membership in the More Severe class was negatively associated with DRSE and positively associated with self-identification as a drinker. There is a distinct class of heavy-drinking college students with a more severe AUD and for whom intervention content needs to be more focused and tailored. Clinical implications are discussed.

Hazardous alcohol consumption among medical students appears to occur at a level comparable to the general population; however, among medical students, it has been found that the motivation to use alcohol partially stems from unique stressors related to their professional training. Although veterinary students may also experience psychological distress in association with their training, little work has focused on the way that these students use alcohol to cope with their distress. The current study sought to examine the severity of depressive symptoms and alcohol consumption among veterinary students as well as students' specific motives for drinking alcohol. The majority of our sample reported experiencing at least one depressive symptom, and a significant proportion engaged in high-risk drinking, with men reporting more harmful alcohol use patterns. Drinking motives related to managing internal bodily and emotional states accounted for variance in drinking patterns. Further, drinking to ameliorate negative emotions partially accounted for the relationship between psychological distress and high-risk drinking. The results of this study suggest that depressive symptoms among veterinary students may be related to harmful drinking patterns, due to alcohol being used as a coping mechanism to regulate emotions. The findings from this study can be used to develop targeted interventions to promote psychological well-being among veterinary students.

Background The literature documents two related yet distinct social normative influences on adolescent drinking. Descriptive norms refer to perceptions of how much others engage in a particular behavior whereas injunctive norms refer to the extent to which others approve of a particular behavior. Theoretical formulations suggest that whether descriptive or injunctive norms guide drinking behavior depends on cognitive factors related to executive functioning. Cognitive capacities, specifically inhibitory control and preplanning, were tested as moderators of the association between social norms and alcohol use using a longitudinal design and community sample of adolescents. Method This longitudinal study included 387 adolescents and three annual waves of data. Behavioral tasks assessed inhibitory control (Stop Signal Task) and preplanning (Tower of London) and social norms and drinking were assessed using self-report measures. Results Significant interactions were found for descriptive and injunctive norms with preplanning and descriptive norms with inhibitory control. As hypothesized, descriptive norms were stronger prospective predictors of alcohol use at low levels of cognitive preplanning whereas injunctive norms were stronger prospective predictors at high levels of cognitive preplanning. Descriptive norms prospectively predicted alcohol use at high, but not at low levels of inhibitory control. Conclusion These findings highlight the complexity of normative influences and suggest that descriptive and injunctive norms have differential effects on future drinking for individuals with different cognitive capacities.

Alcohol use typically is initiated during adolescence, a period that coincides with critical structural and functional maturation of the brain. Brain maturation and associated improvements in decision making continue into the third decade of life, reaching a plateau within the period referred to as emerging adulthood (18-24 years). This particular period covers that of traditionally aged college students, and includes the age (21 years) when alcohol consumption becomes legal in the United States. This review highlights neurobiological evidence indicating the vulnerabilities of the emerging-adult brain to the effects of alcohol. Factors increasing the risks associated with underage alcohol use include the age group's reduced sensitivity to alcohol sedation and increased sensitivity to alcohol-related disruptions in memory. On the individual level, factors increasing those risks are a positive family history of alcoholism, which has a demonstrated effect on brain structure and function, and emerging comorbid psychiatric conditions. These vulnerabilities-of the age group, in general, as well as of particular individuals-likely contribute to excessive and unsupervised drinking in college students. Discouraging alcohol consumption until neurobiological adulthood is reached is important for minimizing alcohol-related disruptions in brain development and decision-making capacity, and for reducing the negative behavioral consequences associated with underage alcohol use.

We aimed to identify drinking rates in a prospectively identified cohort of pregnant women, and subsequently, to identify the drinkers of 48 g or more alcohol/day among them, by using complementary methods for verifying self-reported drinking habits. A research team of social workers and health professionals at the Maipú Clinic, located in a lower middle class neighborhood of Santiago, Chile, conducted interviews of women attending a prenatal clinic between August 1995 and July 2000. Women whose interview responses met predefined criteria (identified in the text) were further evaluated by home visits. We interviewed 9,628 of 10,917 (88%) women receiving prenatal care. By initial interview, 42.6% of women reported no drinking, 57.4% some alcohol consumption, and 3.7% consuming at least one standard drink (15 mL of absolute alcohol) per day. Of the 887 women who had home visits, 101 were identified as consuming on average at least 4 drinks/day (48 g). To determine the best home visit questionnaire items for identifying those drinking at least 4 drinks per day, 48 women who openly admitted drinking this amount were compared with 786 women who were not considered drinkers after the home visit. The 48 self-reported 48 g/day drinkers were significantly more likely to get tipsy when drinking before (p = 0.01) or during (p < 0.0001) pregnancy, to have started drinking at a younger age (p = 0.007), or to exhibit signs of low self-esteem (p < 0.0001), sleep or appetite problems (p < 0.0001), bad interpersonal relationships (p < 0.0001) or having family members with fetal alcohol syndrome features (p < 0.009). In conclusion, using complementary methods of alcohol misuse ascertainment during pregnancy, we found that at least 1% of pregnant women in a Santiago, Chile, clinic population were drinking at levels that are clearly dangerous to the fetus (48 g/day or more). We identified specific interview questions that may help screen for alcohol use of 48 g/day or more in

Alcohol has a wide variety of effects on physiology and behavior. One of the most well-recognized behavioral effects is disinhibition, where behaviors that are normally suppressed are displayed following intoxication. A large body of evidence has shown that alcohol-induced disinhibition in humans affects attention, verbal, sexual, and locomotor behaviors. Similar behavioral disinhibition is also seen in many animal models of ethanol response, from invertebrates to mammals and primates. Here we describe several examples of disinhibition in the nematode C. elegans. The nematode displays distinct behavioral states associated with locomotion (crawling on land and swimming in water) that are mediated by dopamine. On land, animals crawl and feed freely, but these behaviors are inhibited in water. We found that additional behaviors, including a variety of escape responses are also inhibited in water. Whereas alcohol non-specifically impaired locomotion, feeding, and escape responses in worms on land, alcohol specifically disinhibited these behaviors in worms immersed in water. Loss of dopamine signaling relieved disinhibition of feeding behavior, while loss of the D1-like dopamine receptor DOP-4 impaired the ethanol-induced disinhibition of crawling. The powerful genetics and simple nervous system of C. elegans may help uncover conserved molecular mechanisms that underlie alcohol-induced disinhibition of behaviors in higher animals. PMID:24681782

Objective: The purpose of this study was to conduct a meta-analysis summarizing the effectiveness of brief, single-session interventions to reduce alcohol use among heavy drinking college students. Method: A comprehensive literature search identified 73 studies comparing the effects of single-session brief alcohol intervention with treatment-as-usual or no-treatment control conditions on alcohol use among heavy drinking college students. Random-effects meta-analyses with robust variance estimates were used to synthesize 662 effect sizes, estimating the average overall effect of the interventions and the variability in effects across a range of moderators. Results: An overall mean effect size of ḡ = 0.18, 95% CI [0.12, 0.24] indicated that, on average, single-session brief alcohol interventions significantly reduced alcohol use among heavy drinking college students relative to comparison conditions. There was minimal variability in effects associated with study method and quality, general study characteristics, participant demo-graphics, or outcome measure type. However, studies using motivational enhancement therapy/motivational interviewing (MET/MI) modalities reported larger effects than those using psychoeducational therapy (PET) interventions. Further investigation revealed that studies using MET/ MI and feedback-only interventions, but not those using cognitive-behavioral therapy or PET modalities, reported average effect sizes that differed significantly from zero. There was also evidence that long-term effects were weaker than short-term effects. Conclusions: Single-session brief alcohol interventions show modest effects for reducing alcohol consumption among heavy drinking college students and may be particularly effective when they incorporate MET/MI principles. More research is needed to directly compare intervention modalities, to develop more potent interventions, and to explore the persistence of long-term effects. PMID:26098028

Aims This study investigated which ethyl glucuronide immunoassay (EtG-I) cutoff best detects heavy versus light drinking over five days in alcohol dependent outpatients. Methods A total of 121 adults with alcohol use disorders and co-occurring psychiatric disorders taking part in an alcohol treatment study. Participants provided self-reported drinking data and urine samples three time per week for 16-weeks (total samples = 2761). Agreement between low (100 ng/mL, 200 ng/mL), and moderate (500 ng/mL) EtG-I cutoffs and light (women ≤3 standard drinks, men ≤ 4 standard drinks) and heavy drinking (women >3, men >4 standard drinks) were calculated over one to five days. Results The 100 ng/mL cutoff detected >76% of light drinking for two days, and 66% at five days. The 100 ng/mL cutoff detected 84% (1 day) to 79% (5 days) of heavy drinking. The 200 ng/mL cutoff detected >55% of light drinking across five days and >66% of heavy drinking across five days. A 500 ng/mL cutoff identified 68% of light drinking and 78% of heavy drinking for one day, with detection of light (2–5 days <58%) and heavy drinking (2–5 days <71%) decreasing thereafter. Relative to 100 ng/mL, the 200 ng/mL and 500 ng/mL cutoffs were less likely to result in false positives. Conclusions An EtG-I cutoff of 100 ng/mL is most likely to detect heavy drinking for up to five days and any drinking during the previous two days. Cutoffs of ≥ 500 ng/mL are likely to only detect heavy drinking during the previous day. PMID:26475403

Alcohol use disorder, characterized by modest levels of alcohol use, commonly occurs in patients with schizophrenia and dramatically worsens their course. Recent data indicate that the atypical antipsychotic clozapine, but not the typical antipsychotic haloperidol, decreases alcohol drinking both in patients with schizophrenia and also in the Syrian golden hamster, an animal model of moderate alcohol drinking. The present study was designed to assess the comparative effects of clozapine and haloperidol in the alcohol-preferring (P) rat, an animal model of alcoholism. First, the study investigated the comparative effects of clozapine and haloperidol on initiation of alcohol consumption in P rats, which models the early stage of alcoholism. Second, the study assessed the comparative effects of clozapine and haloperidol on maintenance of chronic alcohol consumption in P rats to provide a clue as to whether either drug may also limit alcohol consumption in alcohol-dependent patients. Clozapine attenuated the initiation of alcohol drinking and development of alcohol preference while haloperidol did not. However, neither clozapine nor haloperidol attenuated maintenance of chronic alcohol drinking. Taken together, the current data suggest that clozapine, but not haloperidol, may be effective at reducing alcohol abuse or non-dependent drinking and the P rat, used within an alcohol initiation paradigm, and may differentiate the effects of clozapine and haloperidol on alcohol drinking.

Objective American students studying in foreign countries represent a unique group at risk for increased and problematic drinking. Examination of risk and protective factors for negative alcohol-related consequences can lead to the development of efficacious preventive interventions for reducing high-risk drinking while abroad. The present study examined the relationship between sojourner adjustment (i.e., the sociocultural and psychological adjustment of short-term residents in foreign environments), drinking motives, and alcohol-related consequences. Method Participants were 248 college students (81% women) who recently completed study-abroad trips and completed online surveys about their drinking motives and behavior, alcohol-related consequences, and sojourner adjustment. Results In general, positive sojourner adjustment (i.e., social interaction with host nationals, language development and use, and host culture identification) was protective against negative consequences, whereas negative sojourner adjustment (i.e., social interaction with co-nationals and homesickness/feeling out of place) was associated with increased reporting of consequences. Unexpectedly, the positive sojourner adjustment factor of cultural understanding and participation was associated with greater alcohol-related consequences. Social motives for drinking also predicted consequences. Drinking motives moderated several of the relationships between sojourner adjustment and consequences. Conclusions Interest in and adoption of the host country culture may protect against problematic alcohol use; however, this may vary based on students' reasons for drinking. These findings support the need for further examination of sojourner adjustment in college students abroad and indicate potential areas for development of preventive interventions. PMID:23036220

Objectives: Correct identification of alcohol as a contributor to, or comorbidity of, many psychiatric diseases requires health professionals to be competent and confident to take an accurate alcohol history. Being able to estimate (or calculate) the alcohol content in commonly consumed drinks is a prerequisite for quantifying levels of alcohol consumption. The aim of this study was to assess this ability in medical and nursing students. Methods: A cross-sectional survey of 891 medical and nursing students across different years of training was conducted. Students were asked the alcohol content of 10 different alcoholic drinks by seeing a slide of the drink (with picture, volume and percentage of alcohol by volume) for 30 s. Results: Overall, the mean number of correctly estimated drinks (out of the 10 tested) was 2.4, increasing to just over 3 if a 10% margin of error was used. Wine and premium strength beers were underestimated by over 50% of students. Those who drank alcohol themselves, or who were further on in their clinical training, did better on the task, but overall the levels remained low. Conclusions: Knowledge of, or the ability to work out, the alcohol content of commonly consumed drinks is poor, and further research is needed to understand the reasons for this and the impact this may have on the likelihood to undertake screening or initiate treatment.

This longitudinal study provided a comprehensive examination of age-related changes in alcohol outcome expectancies, subjective evaluation of alcohol outcomes, and automatic alcohol associations in early adolescence. A community sample (52% female, 75% White/Non-Hispanic) was assessed annually for three years (mean age at the first assessment = 11.6 years). Results from growth modeling suggested that perceived likelihood of positive outcomes increased and that subjective evaluations of these outcomes were more positive with age. Perceived likelihood of negative outcomes declined with age. Automatic alcohol associations were assessed with an Implicit Association Task (IAT), and were predominantly negative, but these negative associations weakened with age. High initial levels of perceived likelihood of positive outcomes at age 11 were associated with escalation of drinking. Perceived likelihood of negative outcomes was associated with low risk for drinking at age 11, but not with changes in drinking. Increases in positive evaluations of positive outcomes were associated with increases in alcohol use. Overall, findings suggest that at age 11, youth maintain largely negative attitudes and perceptions about alcohol, but with the transition into adolescence, there is a shift toward a more neutral or ambivalent view of alcohol. Some features of this shift are associated with escalation of drinking. Our findings point to the importance of delineating multiple aspects of alcohol information processing for extending cognitive models of alcohol use to the early stages of drinking. PMID:24841180

Aims (1) To compare affective changes over drinking and non-drinking days among frequent drinkers. (2) To evaluate whether drinkers’ expectations influence affective changes and perceived pleasure and relief from drinking. Design Observational study involving ecological momentary assessments collected via electronic diaries over the course of three weeks. Setting Drinkers’ usual settings in Columbia, MO, USA. Participants 400 adult, frequent drinkers, ages 18–70. Measurements Ecological assessments included morning reports, pre-drinking random prompts, user-initiated first-drink reports, and device-prompted follow-ups over drinking episodes. Participants rated positive (enthusiastic, excited, happy) and negative (distressed, sad) affect and perceived pleasure and relief from drinking in real time. A self-report questionnaire completed at baseline evaluated expectancies for enhanced sociability and tension reduction from drinking. Findings Relative to affective changes over non-drinking days, positive affect increased prior to drinking, 95%CI[.073,.102], and at first drink, 95%CI[.169,.254], whereas negative affect decreased prior to drinking, 95%CI[−.008,−.0005], and at first drink, 95%CI[−.148,−.079]. Sociability expectancies augmented increases in positive affect prior to drinking, 95%CI[.006,.024], and at first drink, 95%CI[.004,.159]). Sociability expectancies also enhanced perceived pleasure from first drinks, 95%CI[.046,.318]. Tension-reduction expectancies attenuated decreases in negative affect at first drink, 95%CI[−.137, −.027], but augmented perceived relief from first drinks, 95%CI[.001,.304]. Conclusions Although theoretical models tend to focus on negative affective outcomes of drinking, changes in positive affect prior to drinking and early in drinking episodes are important for maintaining drinking behavior. Frequent drinkers’ expectations for enhanced sociability or tension reduction from drinking influence their affective

Background Previous studies have shown cultural variations in normative drinking and furthermore, in the quantity and frequency of drinking related to alcohol use disorders. Aim The main goal of this study is to characterize alcohol drinking patterns in Argentinean Emergency Department patients, and secondly, to explore the association between those drinking patterns and DSM-IV alcohol use disorders. Method Data were collected from a probability sample of patients admitted to the Emergency Department of a large public hospital in Mar del Plata, Argentina. Data analyzed here pertain to those who reported consuming at least one drink during the last twelve months (n=529). A factor analysis of multiple correspondences and a hierarchic classification were performed. For the factor analysis, usual quantity and frequency of drinking (for the last 12 months) were considered active variables; number of DSM-IV dependence criteria met, positive or negative diagnostic status for abuse, positive or negative diagnostic status for dependence (both for the last 12 months), and socio-demographic characteristics (age, gender and economic level) were considered illustrative variables. Results The first five factorial axes were retained, accounting for 88% of the total variance. Hierarchic classification resulted in six distinctive classes of drinking patterns. Two patterns were associated with a positive diagnosis of abuse and dependence, respectively. One, drinking between 4 and 6 drinks per occasion mostly on a weekly basis, was associated with a diagnosis of abuse; this pattern was also associated with meeting one or two dependence criteria (dependence orphans). The other, drinking 7 or more drinks per occasion, was associated with a diagnosis of dependence, and also with a diagnostic orphan condition. This class, composed primarily of males, was not characterized by any particular frequency of drinking. The other four drinking patterns were not associated with a positive

Men who have sex with men (MSM) account for the largest proportion of new HIV infections in the United States. Alcohol may facilitate HIV transmission by increasing unprotected anal sex, but few studies have focused on transmission behaviors in HIV-positive MSM. This study explored daily associations between alcohol use and sexual behavior among heavy drinking HIV-positive MSM using a 30-day Timeline Followback interview. Results of generalized estimating equations indicated that greater alcohol consumption on a given day was associated with a linear increase in the odds of having unprotected anal sex with partners of any HIV status. However, the odds of reporting unprotected anal sex with HIV-negative or HIV-status unknown partners increased in a curvilinear fashion, occurring primarily at very heavy levels of use (12+ drinks). Results suggest that very heavy drinking increases the risk of engaging in sexual behavior that has the potential for transmitting HIV to other men.

The relationship between alcohol drinking and the prognosis of nasopharyngeal carcinoma (NPC) is unknown. To investigate the prognostic value of alcohol drinking on NPC, this retrospective study was conducted on 1923 male NPC patients. Patients were classified as current, former and non-drinkers according to their drinking status. Furthermore, they were categorized as heavy drinkers and mild/none drinkers based on the intensity and duration of alcohol drinking. Survival outcomes were compared using Kaplan-Meier analysis and Cox proportional hazards model. We found that current drinkers had significantly lower overall survival (OS) rate (5-year OS: 70.2% vs. 76.4%, P < 0.001) and locoregional recurrence-free survival (LRFS) rate (5-year LRFS: 69.3% vs. 77.5%, P < 0.001) compared with non-drinkers. Drinking ≥14 drinks/week, and drinking ≥20 years were both independent unfavorable prognostic factors for OS (hazard ratio [HR] = 1.38, 95% confidence interval [CI] 1.05-1.81, P = 0.022; HR = 1.38, 95% CI 1.09-1.75, P = 0.007). Stratified analyses further revealed that the negative impacts of alcohol were manifested mainly among older patients and among smokers. In conclusion, alcohol drinking is a useful predictor of prognosis in male NPC patients; drinkers, especially heavy drinkers have poorer prognosis.

We (Kranzler et al. 2014) reported that topiramate 200 mg/day reduced heavy drinking days and increased abstinent days in 138 heavy drinkers whose treatment goal was to reduce drinking to safe levels. In that 12-week, placebo-controlled study, we measured drinking using the Timeline Follow-back method at each treatment visit. In addition to the intent-to-treat effects of topiramate, we found that a single nucleotide polymorphism (rs2832407) in GRIK1, encoding the GluK1 subunit of the kainate receptor, moderated the treatment effect in European Americans (EAs; n=122). Topiramate reduced heavy drinking only in rs2832407*C allele homozygotes. Here, we augment those analyses by using patients’ daily reports obtained using interactive voice response technology (a) to validate the interactive effects of GRIK1 and topiramate as predictors of drinking level and (b) to examine changes in expected positive effects of drinking (i.e., positive outcome expectancies) and desire to drink. We found that rs2832407*C allele homozygotes treated with topiramate drank less overall during treatment than those receiving placebo, validating our earlier findings for heavy drinking days (Kranzler et al. 2014). There was also a study day × medication group × genotype group interaction that predicted both positive alcohol expectancies and desire to drink, with rs2832407*C-allele homozygotes treated with topiramate showing the largest decreases in these outcomes during the study period. Changes in positive alcohol expectancies or desire to drink did not mediate the effects on drinking. These findings validate and extend our previous pharmacogenetic findings with topiramate.

This chapter reviews selected epidemiologic studies on drinking and associated problems among US ethnic minorities. Ethnic minorities and the White majority group exhibit important differences in alcohol use and related problems, including alcohol use disorders. Studies show a higher rate of binge drinking, drinking above guidelines, alcohol abuse, and dependence for major ethnic and racial groups, notably, Blacks, Hispanics, and American Indians/Alaskan Natives. Other problems with a higher prevalence in certain minority groups are, for example, cancer (Blacks), cirrhosis (Hispanics), fetal alcohol syndrome (Blacks and American Indians/Alaskan Natives), drinking and driving (Hispanics, American Indians/Alaskan Natives). There are also considerable differences in rates of drinking and problems within certain ethnic groups such as Hispanics, Asian Americans, and American Indians/Alaskan Natives. For instance, among Hispanics, Puerto Ricans and Mexican Americans drink more and have higher rates of disorders such as alcohol abuse and dependence than Cuban Americans. Disparities also affect the trajectory of heavy drinking and the course of alcohol dependence among minorities. Theoretic accounts of these disparities generally attribute them to the historic experience of discrimination and to minority socioeconomic disadvantages at individual and environmental levels.

Objective Alcohol screening is uncommon among college students; however, many students display references to alcohol on Facebook. The objective of this study was to examine associations between displayed alcohol use and intoxication/problem drinking (I/PD) references on Facebook and self-reported problem drinking using a clinical scale. Design Content analysis and cross-sectional survey Setting www.Facebook.com Participants Undergraduate students from two state universities between the ages of 18 and 20 with public Facebook profiles Main exposures Profiles were categorized into one of three distinct categories: Non-Displayers, Alcohol Displayers and Intoxication/Problem Drinking (I/PD) Displayers. Outcome measures An online survey measured problem drinking using the AUDIT scale. Analyses examined associations between alcohol display category and 1) AUDIT problem drinking category using logistic regression, 2) AUDIT score using negative binomial regression, and 3) alcohol-related injury using Fisher’s exact test. Results Of 307 profiles identified, 224 participants completed the survey (73% response rate). The average age was 18.8 years, 122 (54%) were female, 152 (68%) were Caucasian, and approximately half were from each university. Profile owners who displayed I/PD were more likely (OR=4.4 [95% CI 2.0-9.4]) to score in the problem drinking category of the AUDIT scale, had 64% (IRR=1.64 [95% CI: 1.27-11.0] higher AUDIT scores overall and were more likely to report an alcohol-related injury in the past year (p=0.002). Conclusions Displayed references to I/PD were positively associated with AUDIT scores suggesting problem drinking as well as alcohol-related injury. Results suggest that clinical criteria for problem drinking can be applied to Facebook alcohol references. PMID:21969360

Although the biphasic effects of acute alcohol during ascending and descending Breath Alcohol Concentrations (BrACs) are well described, the plateau period between peak and steadily descending BrACs is generally unrecognized and under-studied by researchers. Naturalistic examinations indicate such periods persist for substantial intervals, with a time frame of onset suggesting BrAC plateaus may co-occur with potentially risky behaviors (e.g., driving). The current pilot study examined neurocognitive performance during this period. Participants were healthy, community-residing moderate drinkers (n = 18). In the first phase of the study, the Digit Symbol Substitution and Trail Making Tasks were administered during BrAC plateau (M = 62 mg/dL). BrACs were negatively correlated with Digit Symbol performance but unrelated to other tasks. In contrast, performance on a derived Trail Making measure of set-shifting was positively associated with the maximum alcohol doses consumed in the preceding 6 months. Phase 2 analyses demonstrated that relationships between previous alcohol experience and cognitive performance were absent among individuals receiving placebo beverages. Taken together, these data suggest a relationship worthy of investigation between previous drinking experiences and cognitive flexibility during the plateau phase.

Rationale Impulsive behavior is associated with both alcohol use disorders and a family history of alcoholism (FHA). One operational definition of impulsive behavior is the stop signal task (SST), which measures the time needed to stop a ballistic hand movement. Objective Employ functional magnetic resonance imaging (fMRI) to study right frontal responses to stop signals in heavy drinking subjects with and without FHA, and as a function of alcohol exposure. Methods Twenty two family history positive (FHP; age = 22.7 years, SD= 1.9) and 18 family history negative (FHN; age = 23.7, SD= 1.8) subjects performed the SST in fMRI in two randomized visits: once during intravenous infusion of alcohol, clamped at a steady-state breath alcohol (BrAC) concentration of 60mg%, and once during infusion of placebo saline. An independent reference group (n= 13, age= 23.7, SD= 1.8) was used to identify a priori right prefrontal regions activated by successful inhibition (Inh) trials, relative to ‘Go’ trials that carried no need for inhibition (Inh > Go). Results FHA interacted with alcohol exposure in right prefrontal cortex, where alcohol reduced [Inh > Go] activation in FHN subjects, but not in FHP subjects. Within this right frontal cortical region, stop signal reaction time (SSRT) also correlated negatively with [Inh > Go] activation, suggesting that the [Inh > Go] activity was related to inhibitory behavior. Conclusions The results are consistent with the low level of response theory (Schuckit, 1980; Quinn & Fromme, 2011), with FHP being less sensitive to alcohol’s effects. PMID:23468100

The motivational model of alcohol use posits that individuals may consume alcohol to cope with negative affect. Conflict with others is a strong predictor of coping motives, which in turn predict alcohol-related problems. Two studies examined links between conflict, coping motives, and alcohol-related problems in emerging adult romantic dyads. It was hypothesized that the association between conflict and alcohol-related problems would be mediated by coping-depression and coping-anxiety motives. It was also hypothesized that this would be true for actor (i.e., how individual factors influence individual behaviors) and partner effects (i.e., how partner factors influence individual behaviors) and at the between- (i.e., does not vary over the study period) and within-subjects (i.e., varies over the study period) levels. Both studies examined participants currently in a romantic relationship who consumed ≥12 alcoholic drinks in the past year. Study 1 was cross-sectional using university students (N = 130 students; 86.9% female; M = 21.02 years old, SD = 3.43). Study 2 used a 4-wave, 4-week longitudinal design with romantic dyads (N = 100 dyads; 89% heterosexual; M = 22.13 years old, SD = 5.67). In Study 2, coping-depression motives emerged as the strongest mediator of the conflict-alcohol-related problems association, and findings held for actor effects but not partner effects. Supplemental analyses revealed that this mediational pathway only held among women. Within any given week, alcohol-related problems changed systematically in the same direction between romantic partners. Interventions may wish to target coping-depression drinking motives within couples in response to conflict to reduce alcohol-related problems.

Multiple lines of high alcohol-preferring (HAP) mice were selectively bred for their intake of 10% ethanol (v/v) during 24-hour daily access over a 4-week period, with the highest drinking lines exhibiting intakes in excess of 20 g/kg/day. We observed circadian drinking patterns and resulting blood ethanol concentrations (BECs) in the HAP lines. We also compared the drinking rhythms and corresponding BECs of the highest drinking HAP lines to those of the C57BL/6J (B6) inbred strain. Adult male and female crossed HAP (cHAP), HAP replicate lines 1, 2, 3 and B6 mice had free-choice access to 10% ethanol and water for 3 weeks prior to bi-hourly assessments of intake throughout the dark portion of the light-dark cycle. All HAP lines reached and maintained a rate of alcohol intake above the rate at which HAP1 mice metabolize alcohol, and BECs were consistent with this finding. Further, cHAP and HAP1 mice maintained an excessive level of intake throughout the dark portion of the cycle, accumulating mean BEC levels of 261.5 ± 18.09 and 217.9 ± 25.02 mg/dl, respectively. B6 mice drank comparatively modestly, and did not accumulate high BEC levels (53.63 + 8.15 mg/dl). Free-choice drinking demonstrated by the HAP1 and cHAP lines may provide a unique opportunity for modeling the excessive intake that often occurs in alcohol-dependent individuals, and allow for exploration of predisposing factors for excessive consumption, as well as the development of physiological, behavioral and toxicological outcomes following alcohol exposure.

Alcohol use has been linked to risky sexual practices among adolescents. However, limited research on alcohol use and risky sexual behavior has been conducted among female adolescents. This study examined a high quantity of alcohol as a longitudinal predictor of risky sexual behavior and sexually transmitted diseases (STDs) among female adolescents. Three hundred ninety-three adolescent females aged 15-21 were assessed for alcohol use and risky sexual behaviors. Participants also provided 2 swab specimens that were assayed for STDs. Use of high alcohol quantity was defined as > or = 3 drinks in 1 sitting. Binary generalized estimating equation models were conducted assessing the impact of alcohol use at baseline on risky sexual behavior and STDs over a 12-month period. Age, intervention group and baseline outcome measures were entered as covariates. The results indicated that use of high alcohol quantity predicted inconsistent condom use, high sexual sensation seeking, multiple sexual partners, sex while high on alcohol or drugs, and having anal sex during 12-month follow-up period. These findings suggest that STD-related behavioral interventions for adolescents should discuss the link between alcohol and STD-risk behavior. Deeper understanding of alcohol as a predictor of risky sexual behavior among female adolescents is of paramount importance for development of efficient prevention programs at individual and community levels. The risk of acquiring an STD is higher among teenagers than among adults.

This study aimed to investigate alcoholic beverages drinking and predictive factors among female students. The participants were 377 subjects from 3 high schools in a tourist province, of Thailand. Data collection was done through self-administered questionnaire. Scales of the questionnaire had reliability coefficients ranging from 0.84 - 0.88. The data were analyzed by using descriptive and inferential statistics. The findings revealed as follows. About half (51%) of them have ever drunk and 10.5% of drinkers have drunk once a week. In addition, 15.6% of drinkers began their first drink when they were under 10 years old. Risk factors for alcohol consumption of female student were age, GPA, drinker in family, peer pressure, advertisement and accessibility to alcoholic beverages while protective factors were perception of drinking impacts on family and moral values. Students who have a drinking family member were 4.6 times more likely to drink than those who do not have.

Social norms-based interventions have shown promise in reducing drinking behavior and resulting consequences in young adults. Although most research has focused on young civilians (i.e., college students), some studies have investigated social norms-based interventions with active duty military and veteran samples. Yet, research has not yet determined how to maximize the effectiveness of social norms-based intervention in this heavy drinking population. As an initial step toward this goal, the current study utilized a community sample of 1,023 young adult veterans to examine: (1) whether veteran perceptions of the drinking behavior of their veteran peers differ from their perceptions of civilian drinking behavior, (2) whether perceptions of specific veteran groups differ from actual drinking behavior of veterans within those groups, (3) what levels of specificity in reference groups (same-gender civilians, same-branch veterans, same-gender veterans, or same-branch-and-same-gender veterans) are most strongly associated with veterans’ own drinking, and (4) whether perceptions about others’ attitudes toward drinking also contribute independently of perceived behavioral norms to veteran drinking. Findings indicated that participants perceived that other veterans drank more than civilians and that veteran groups drank more than veterans in the sample actually drank. Veteran-specific perceived behavioral norms were similar in their associations with drinking outcomes, whereas same-gender civilian perceived behavioral norms exhibited little or no associations with drinking. Veteran-specific perceived attitudinal norms exhibited little or no association on drinking behavior after controlling for perceived behavioral norms. These findings can be used to inform the development of social norms
