Consuming an unhealthy level of alcohol is a significant problem for some young women. Potential determinants of excess consumption include perceptions of usual consumption among peers-perceptions of what is "normal." The present study examined whether perceptions of social normative endorsement of drinking, operationalized by measures of perceived alcohol consumption of close friends (proximal norms), the consumption of the "average student" (distal norms), and the extent of alcohol-related content posted by peers on Facebook were related to alcohol-related attitudes and self-reported consumption. Female university students (n=129; Mage=21.48 years, SD=3.00) completed an online questionnaire assessing Facebook use, perceived alcohol-related norms, and self-reported alcohol attitudes and consumption. Perceptions of the consumption of the average female student were a negative predictor of attitudes. Positive alcohol attitudes, extent of own alcohol-related photographic posts on Facebook, average female student alcohol consumption, and report of male close friend consumption predicted self-report of own alcohol consumption. Interestingly, female close friend norms failed to predict consumption, whereas male close friend norms predicted consumption but not attitudes, suggesting the possibility of separate cognitive pathways for alcohol-related attitudes and behavior. This study builds on existing research by casting new light on predictors of alcohol-related attitudes, as well as describing the potential role of social networking sites such as Facebook in the formation of social norms and the modulation of drinking behavior.

Many individuals wait until alcohol use becomes severe before treatment is sought. However, social networks, or the number of social groups an individual belongs to, may play a moderating role in this relationship. Logistic regression examined the interaction of alcohol consumption and social networks as a predictor of treatment utilization while adjusting for sociodemographic and clinical variables among 1,433 lifetime alcohol-dependent respondents from wave 2 of the National Epidemiologic Survey on Alcohol Related Conditions (NESARC). Results showed that social networks moderate the relationship between alcohol consumption and treatment utilization such that for individuals with few network ties, the relationship between alcohol consumption and treatment utilization was diminished, compared to the relationship between alcohol consumption and treatment utilization for individuals with many network ties. Findings offer insight into how social networks, at times, can influence individuals to pursue treatment, while at other times, influence individuals to stay out of treatment, or seek treatment substitutes.

The negative consequences of chronic alcohol abuse are well known, but heavy episodic consumption ("binge drinking") is also associated with significant personal and societal harms. Aggressive tendencies are increased after alcohol but the mechanisms underlying these changes are not fully understood. While effects on behavioural control are likely to be important, other effects may be involved given the widespread action of alcohol. Altered processing of social signals is associated with changes in social behaviours, including aggression, but until recently there has been little research investigating the effects of acute alcohol consumption on these outcomes. Recent work investigating the effects of acute alcohol on emotional face processing has suggested reduced sensitivity to submissive signals (sad faces) and increased perceptual bias towards provocative signals (angry faces) after alcohol consumption, which may play a role in alcohol-related aggression. Here we discuss a putative mechanism that may explain how alcohol consumption influences emotional processing and subsequent aggressive responding, via disruption of orbitofrontal cortex (OFC)-amygdala connectivity. While the importance of emotional processing on social behaviours is well established, research into acute alcohol consumption and emotional processing is still in its infancy. Further research is needed and we outline a research agenda to address gaps in the literature.

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.

Personality and expectancies are relevant psychological factors for the development of adolescent alcohol use and misuse. The present study examined their direct, mediated and moderated effects on different drinking behaviors in adolescence. Personality domains of the five-factor model, positive and negative alcohol expectancies (AEs), alcohol use during the week and the weekend, and alcohol-related problems were assessed in a sample of 361 adolescents. Different personality dimensions were directly associated with specific alcohol outcomes: Extraversion, low Conscientiousness and low Openness were associated with weekend alcohol use; low Agreeableness was related to weekday use; whereas low Agreeableness, low Conscientiousness and Extraversion were associated with alcohol-related problems. In addition, positive AEs mediated the relationship between Extraversion and alcohol use, whereas both positive and negative expectancies mediated the association between Neuroticism and alcohol consumption and alcohol-related problems. Finally, both types of expectancies interacted with Extraversion to predict alcohol problems. Our results highlight the importance of examining the complex interplay of comprehensive personality models and AEs to gain a better understanding of the development of different alcohol use and misuse patterns in adolescence.

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: National population data on racial/ethnic disparities and risk of alcohol-related injury are scarce. Alcohol-related injury and drinking patterns are examined in a sample of respondents from four (1995, 2000, 2005, 2010) U.S. National Alcohol Surveys using risk function analysis. Method: Self-reported consumption of 15,476 current drinkers was assessed as the average number of drinks consumed monthly and, separately, the frequency of consuming five or more drinks in a day (5+ days) in the last year. Alcohol-related injury was defined as drinking within 6 hours before the event. Risk curves were defined, separately for Whites, Blacks, and Hispanics, using fractional polynomial regression. Results: Risk was greatest for Hispanics to 110 drinks per month (3–4 drinks per day) and above 240 drinks per month, whereas risk was greatest for Whites between these levels. Blacks were at lower risk at all monthly volume levels when demographic and socioeconomic status characteristics were controlled for. Whites had the highest risk of an alcohol-related injury based on 5+ drinking days at all levels up to nearly daily 5+ drinking, whereas Blacks had the lowest risk at all levels of 5+ drinking. Conclusions: A disparity in alcohol-related injury was found for Hispanics compared with Whites at the same average monthly volume of consumption at lower and higher volume levels, but not at the same number of 5+ drinking days, and a lower risk of alcohol-related injury was found for Blacks for both consumption measures when demographic and socioeconomic status characteristics were taken into account. Although exposure to hazards other than alcohol, which could account for some of the racial/ethnic disparity observed, was not taken into account, these mixed findings suggest this is an important area deserving future research attention.

Alcohol-related diseases of the nervous system are caused by excessive exposures to alcohol, with or without co-existing nutritional or vitamin deficiencies. Toxic and metabolic effects of alcohol (ethanol) vary with brain region, age/developmental stage, dose, and duration of exposures. In the mature brain, heavy chronic or binge alcohol exposures can cause severe debilitating diseases of the central and peripheral nervous systems, and skeletal muscle. Most commonly, long-standing heavy alcohol abuse leads to disproportionate loss of cerebral white matter and impairments in executive function. The cerebellum (especially the vermis), cortical-limbic circuits, skeletal muscle, and peripheral nerves are also important targets of chronic alcohol-related metabolic injury and degeneration. Although all cell types within the nervous system are vulnerable to the toxic, metabolic, and degenerative effects of alcohol, astrocytes, oligodendrocytes, and synaptic terminals are major targets, accounting for the white matter atrophy, neural inflammation and toxicity, and impairments in synaptogenesis. Besides chronic degenerative neuropathology, alcoholics are predisposed to develop severe potentially life-threatening acute or subacute symmetrical hemorrhagic injury in the diencephalon and brainstem due to thiamine deficiency, which exerts toxic/metabolic effects on glia, myelin, and the microvasculature. Alcohol also has devastating neurotoxic and teratogenic effects on the developing brain in association with fetal alcohol spectrum disorder/fetal alcohol syndrome. Alcohol impairs function of neurons and glia, disrupting a broad array of functions including neuronal survival, cell migration, and glial cell (astrocytes and oligodendrocytes) differentiation. Further progress is needed to better understand the pathophysiology of this exposure-related constellation of nervous system diseases and better correlate the underlying pathology with in vivo imaging and biochemical lesions

The study of older adults is relatively new for the social sciences. There is a growing awareness of the alcohol-related problems in this population. Between 2 and 10 percent of older social drinkers present severe alcohol-related problems of different kinds. Three terms describe the major consequences of "too much" alcohol: intoxication,…
The approach to treating alcohol-related problems in primary care settings needs: 1) to recognize the incidence of alcohol-related problems in primary care settings; 2) to know the way of screening; 3) to know how to help patients; and 4) to know enough about treating alcoholism to appropriately refer patients for additional help. This article looks research evidence about the incidence of alcohol-related problems in primary care and recognition of incidence and way of screening of alcohol-related problems by primary care physicians in Japan. Then this article describes evidence-based as well as author's experience-based approach to treat the alcohol-related health problems in primary care settings. In line with the newly introduced law to prevent the alcohol-related health problems and the anticipating introduction of new specialty of general medicine, early intervention to alcohol-related problems in primary care settings will be much appreciated. To do so, enough amounts of education and research are needed.

The direct and interactive effects of alcohol expectancies for aggression, dispositional hostility, and heavy alcohol consumption on alcohol-related physical aggression were examined across the first four years of marriage in a sample of 634 newlywed couples. For husbands, alcohol aggression expectancies predicted increases in alcohol-related aggression; across husbands and wives, however, aggression expectancies were not found to interact with hostility or alcohol consumption to predict physical aggression. Consistent with previous research, hostility and alcohol consumption interacted with each other to predict alcohol-related aggression. Specifically, for both husbands and wives high in dispositional hostility, heavy alcohol consumption was positively associated with the occurrence of alcohol-related aggression; for those low in dispositional hostility, however, there was no association between alcohol consumption and alcohol-related aggression. Findings are contrasted with previous longitudinal research on alcohol aggression expectancies and physical aggression in married couples. The article discusses the extent to which findings may vary depending on whether expectancies are assessed in relation to alcohol's effect on one's own behavior versus alcohol's effect on others' behavior.

This study, based on a stratified (by decade of production) random sample of 1,221 animated cartoons and 4,201 characters appearing in those cartoons, seeks to determine the prevalence of alcohol-related content; how, if at all, the prevalence changed between 1930 and 1996 (the years spanned by this research); and the types of messages that animated cartoons convey about beverage alcohol and drinking in terms of the characteristics that are associated with alcohol use, the contexts in which alcohol is used in cartoons, and the reasons why cartoon characters purportedly consume alcohol. Approximately 1 cartoon in 11 was found to contain alcohol-related content, indicating that the average child or adolescent viewer is exposed to approximately 24 alcohol-related messages each week just from the cartoons that he/she watches. Data indicated that the prevalence of alcohol-related content declined significantly over the years. Quite often, alcohol consumption was shown to result in no effects whatsoever for the drinker, and alcohol use often occurred when characters were alone. Overall, mixed, ambivalent messages were provided about drinking and the types of characters that did/not consume alcoholic beverages.

Alcohol consumption may be influenced by the local alcohol retailing environment. This study is the first to examine neighbourhood alcohol outlet availability (on- and off-sales outlets) and alcohol-related health outcomes in Scotland. Alcohol-related hospitalisations and deaths were significantly higher in neighbourhoods with higher outlet densities, and off-sales outlets were more important than on-sales outlets. The relationships held for most age groups, including those under the legal minimum drinking age, although were not significant for the youngest legal drinkers (18–25 years). Alcohol-related deaths and hospitalisations were higher in more income-deprived neighbourhoods, and the gradient in deaths (but not hospitalisations) was marginally larger in neighbourhoods with higher off-sales outlet densities. Efforts to reduce alcohol-related harm should consider the potentially important role of the alcohol retail environment. PMID:25840352

In China, alcohol consumption is increasing faster than anywhere else in the world. A steady increase in alcohol production has also been observed in the country, together with a rise in alcohol-related harm. Despite these trends, China's policies on the sale and consumption of alcoholic beverages are weak compared with those of other countries in Asia. Weakest of all are its policies on taxation, drink driving laws, alcohol sale to minors and marketing licenses. The authors of this descriptive paper draw attention to the urgent need for public health professionals and government officials in China to prioritize population surveillance, research and interventions designed to reduce alcohol use disorders. They describe China's current alcohol policies and recent trends in alcohol-related harm and highlight the need for health officials to conduct a thorough policy review from a public health perspective, using as a model the World Health Organization's global strategy to reduce the harmful use of alcohol.

One of the sequelae of chronic alcohol abuse is malnutrition. Importantly, a deficiency in thiamine (vitamin B(1)) can result in the acute, potentially reversible neurological disorder Wernicke encephalopathy (WE). When WE is recognized, thiamine treatment can elicit a rapid clinical recovery. If WE is left untreated, however, patients can develop Korsakoff syndrome (KS), a severe neurological disorder characterized by anterograde amnesia. Alcohol-related brain damage (ARBD) describes the effects of chronic alcohol consumption on human brain structure and function in the absence of more discrete and well-characterized neurological concomitants of alcoholism such as WE and KS. Through knowledge of both the well-described changes in brain structure and function that are evident in alcohol-related disorders such as WE and KS and the clinical outcomes associated with these changes, researchers have begun to gain a better understanding of ARBD. This Review examines ARBD from the perspective of WE and KS, exploring the clinical presentations, postmortem brain pathology, in vivo MRI findings and potential molecular mechanisms associated with these conditions. An awareness of the consequences of chronic alcohol consumption on human behavior and brain structure can enable clinicians to improve detection and treatment of ARBD.

We studied alcohol consumption and its consequences as a seasonal phenomenon in Estonia and analysed the social and environmental factors that may cause its seasonal rhythm. There are two important questions when researching the seasonality of human activities: (1) whether it is caused by natural or social factors, and (2) whether the impact of the factors is direct or indirect. Often the seasonality of social phenomena is caused by social factors, but the triggering mechanisms are related to environmental factors like temperature, precipitation, and radiation via the circannual calendar. The indicators of alcohol consumption in the current paper are grouped as: (1) pre-consumption phenomena, i.e. production, tax and excise, sales (beer, wine and vodka are analysed separately), and (2) post-consumption phenomena, i.e. alcohol-related crime and traffic accidents and the number of people detained in lockups and admitted to alcohol treatment clinics. In addition, seasonal variability in the amount of alcohol advertising has been studied, and a survey has been carried out among 87 students of Tartu University. The analysis shows that different phenomena related to alcohol have a clear seasonal rhythm in Estonia. The peak period of phenomena related to beer is in the summer, from June to August and the low point is during the first months of the year. Beer consumption correlates well with air temperature. The consumption of vodka increases sharply at the end of the year and in June; the production of vodka does not have a significant correlation with negative temperatures. The consumption of wine increases during summer and in December. The consequences of alcohol consumption, expressed as the rate of traffic accidents or the frequency of medical treatment, also show seasonal variability. Seasonal variability of alcohol consumption in Estonia is influenced by natural factors (temperature, humidity, etc.) and by social factors (celebrations, vacations, etc.). However

Alcohol's adverse public health impact includes disease, injury, violence, disability, social problems, psychiatric illness, drunk driving, drug use, unsafe sex, and premature death. Furthermore, alcohol is a confirmed human carcinogen. The International Agency for Research on Cancer concluded that alcohol causes cancer of the oral cavity, pharynx, larynx, esophagus, liver, colon-rectum, and breast. World Cancer Research Fund/American Institute for Cancer Research concluded that the evidence justifies recommending avoidance of consuming any alcohol, even in small quantities. Despite being responsible for 3.8% of global deaths (2,255,000 deaths) and 4.6% of global disability-adjusted life years in 2004, alcohol consumption is increasing rapidly in China and Asia. Contrary to the World Health Assembly's call for global control action, Hong Kong has reduced wine and beer taxes to zero since 2008. An International Framework Convention on Alcohol Control is urgently needed. Increasing alcohol taxation and banning alcohol advertisement and promotion are among the most effective policies.

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.

The primary goal of this investigation was to determine whether executive functioning (EF) would moderate the alcohol-aggression relation. Participants were 310 (152 men and 158 women) healthy social drinkers between 21 and 35 years of age. EF as well as non-EF skills were measured with 13 validated neuropsychological tests. Following the consumption of either an alcoholic or a placebo beverage, participants were tested on a modified version of the Taylor Aggression Paradigm (S. Taylor, 1967), in which mild electric shocks were received from, and administered to, a fictitious opponent. Aggressive behavior was operationalized as the shock intensities administered to the fictitious opponent. EF was negatively related to aggressive behavior for men, regardless of beverage group, even when controlling for non-EF skills. Furthermore, alcohol increased aggression only for men with lower EF scores. Finally, the mere belief that alcohol was consumed suppressed aggression for women but not for men.

The prevalence of alcohol-related regretted sex in college students warrants a better understanding of the characteristics of students who report such experiences. Therefore, the present study examined correlates of regretted sexual experiences involving alcohol use among 2 specific high-risk college student samples: students mandated to alcohol intervention (n = 522) and volunteer 1st-year students transitioning to college (n = 481). Results indicated that alcohol-related regretted sex occurred at similar rates in mandated and volunteer students, with approximately 25% of the students reporting at least 1 occurrence in the past month. Women were more likely to report alcohol-related regretted sex compared with men. The belief that alcohol use would result in "liquid courage" was associated with alcohol-related regretted sex among college students, even after accounting for greater alcohol use and problem alcohol use behaviors. These findings have significant implications for intervention efforts and future research.

Alcohol-related injuries are responsible for a large share of the global mortality and morbidity burden. Scant information existed, however, for Switzerland. Based on 3653 injured patients and 3519 patients attending the emergency department of the Lausanne University Hospital for other reasons, alcohol attributable fractions with regard to the alcohol consumption in the 6 hours before the injury were estimated. Among men 17% of all injures were alcohol attributable, and 12% among women. Relative risks increased in dose-response relationship with alcohol intake. Leisure time related injuries were most likely to be alcohol attributable. Most of the alcohol-related injuries occurred at already small ethanol quantities ingested.

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.

Internationally, violence in the emergency department (ED) is of a constant concern to emergency practitioners. Frequently, both original research papers and anecdotal reports emphasise the phenomenon of alcohol related aggression in the ED. In this first paper, we highlight the literatures discussion of alcohol related violence in the emergency department and the potential psychological effects of alcohol intoxication. In the second we offer personal and organisational strategies clinical nursing staff may consider appropriate to minimise the risk of assault when caring for service users projecting alcohol related aggression.

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.

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.

Context Alcohol consumption has escalated rapidly in many countries over the past decade. Evidence suggests a correlation between alcohol use and cognitive decline. We have systematically reviewed the concept and controversies, epidemiology, nosology, neuropathology and neurobiology, neuropsychology and management updates of alcohol-related dementia (ARD) in this paper. Evidence Acquisition We retrieved papers for this review by searching the PubMed database for terms “alcohol and dementia”, “alcohol and cognitive impairment”, and “alcohol and wernicke-korsakoff” mentioned in the title of the published papers. A total of 131 studies showed up. Appropriate studies were shortlisted and included (n = 72). Cross-references if relevant were considered from the selected studies. Eligible articles were fully read by the authors and the results were compiled. Results The prolonged and excessive use of alcohol may lead to structural and functional brain damage, leading to ARD. The cognitive deficits are most frequently observed in domains of visuospatial functions, memory and executive tasks, with a potential of partial recovery if abstinence is maintained. However, there are doubts regarding the etiopathogenesis, nosological status, prevalence and diagnostic criteria for ARD, due to difficulty in assessment and various confounding factors. Conclusions With growing cohort of young and middle-aged people, there is a probable risk of upsurge of ARD. Presently, there are dilemmas over the diagnosis of independent ARD. Thus, there is a need to develop evidence-based guidelines for diagnosis and management of ARD through further systematic studies. PMID:27818965

Violence in the emergency department (ED) is a global problem. In our first paper, we highlighted the potential psychological effects of alcohol intoxication, the literatures discussion of alcohol related violence in the emergency department and the importance of developing positive nurse/service user relationships. In this second paper, we discuss personal and organisational strategies clinical nursing staff may consider appropriate to minimise the risk of assault when caring for service users projecting alcohol related aggression.

Alcohol-related health policy research is responsible for guiding the implementation of laws and public health policies that have reduced alcohol-related highway injuries and deaths, as well as other alcohol-related problems over the last 40 years. This research, which tests theories about potential policy changes and responds to specific problems, has examined a vast array of prevention programs. This article briefly identifies 10 program categories and highlights four programs to illustrate the scope and complexity of the individual health policy areas within the categories. PMID:23579933

Alcohol affects the liver through metabolic disturbances associated with its oxidation. Redox changes produced by the hepatic alcohol dehydrogenase pathway affect lipid, carbohydrate and protein metabolism. Ethanol is also oxidized in liver microsomes by the ethanol-inducible cytochrome P4502E1, resulting in ethanol tolerance and selective hepatic perivenular damage. Furthermore, P4502E1 activates various xenobiotics, explaining the increased susceptibility of the heavy drinker to the toxicity of anesthetics, commonly used medications (i.e. isoniazid), analgesics (i.e. acetaminophen), and chemical carcinogens. Induction of microsomal enzymes also contributes to vitamin A depletion, enhances its hepatotoxicity and results in increased acetaldehyde generation from ethanol, with formation of protein adducts, glutathione depletion, free-radical-mediated toxicity, and lipid peroxidation. Chronic ethanol consumption strikingly enhances the number of hepatic collagen-producing activated lipocytes. Both in vivo (in our baboon model of alcoholic cirrhosis) and in vitro (in cultured myofibroblasts and activated lipocytes) ethanol and/or its metabolite acetaldehyde increase collagen accumulation and mRNA for collagen. Gender differences are related, in part, to lower gastric ADH activity (with consequent reduction of first pass ethanol metabolism) in young women, decreased hepatic fatty acid binding protein and increased free-fatty acid levels as well as lesser omega-hydroxylation, all of which result in increased vulnerability to ethanol. Elucidation of the biochemical effects of ethanol are now resulting in improved therapy: in baboons, S-adenosyl-L-methionine attenuates the ethanol-induced glutathione depletion and associated mitochondrial lesions, and polyenylphosphatidylcholine opposes the ethanol-induced hepatic phospholipid depletion, the decrease in phosphatidylethanolamine methyltransferase activity and the activation of hepatic lipocytes, with full prevention of

Based on the review of scientific papers and institutional reports on the subject and analysis of some secondary data, we assess the alcohol-related harm in Spain between 1990 and 2011. In 2011 they could be attributable to alcohol, 10% of the total mortality of the population aged 15-64, and about 30% of deaths due to traffic accidents. Among the population aged 15-64 years at least 0.8% had alcohol use disorders, an additional 5% could have harmful alcohol consumption that would need clinical evaluation, and about 20% had had some acute alcohol intoxication (AAI) in the last year. The AAI accounted for approximately 0.5-1.1 % of hospital emergency visits. Social costs of alcohol could represent 1% of gross domestic product. The prevalence of alcohol-related harm was significantly higher in men than women, with a male/female ratio greater than three for alcohol-related mortality and serious injuries, and this situation has hardly changed in the last 20 years. Alcohol-related harm has followed a downward trend, except for AAI. In 1990-2011 the standardized mortality rates related to alcohol decreased by half. Large gaps in knowledge and uncertainties on alcohol-related harm in Spanish population, clearly justify the institutional support for the research in this field and the implementation of a comprehensive monitoring system.

The purpose of this investigation was to examine (a) whether irritability mediates the relation between executive functioning (EF) and alcohol-related aggression and (b) whether the alcohol-aggression relation is better explained by the interactive effects of EF and irritability above and beyond the effects of either variable alone. EF was measured using seven well-established neuropsychological tests. Irritability was assessed with the Caprara Irritability Scale. Participants were 313 male and female social drinkers between 21 and 35 years of age. Following the consumption of an alcohol or a placebo beverage, participants were tested on a laboratory aggression task in which electric shocks were given to and received from a fictitious opponent under the guise of a competitive reaction-time task. Aggression was operationalized as the shock intensities administered to the fictitious opponent. Results indicated that irritability successfully mediated the relation between EF and intoxicated aggression for men only. Despite the fact that irritability and EF both independently moderated the alcohol-aggression relation in previous studies, no significant interaction for their combined effect was detected here. The findings are discussed, in part, within a cognitive neoassociationistic framework for aggressive behavior.

Abstract In China, alcohol consumption is increasing faster than anywhere else in the world. A steady increase in alcohol production has also been observed in the country, together with a rise in alcohol-related harm. Despite these trends, China’s policies on the sale and consumption of alcoholic beverages are weak compared with those of other countries in Asia. Weakest of all are its policies on taxation, drink driving laws, alcohol sale to minors and marketing licenses. The authors of this descriptive paper draw attention to the urgent need for public health professionals and government officials in China to prioritize population surveillance, research and interventions designed to reduce alcohol use disorders. They describe China’s current alcohol policies and recent trends in alcohol-related harm and highlight the need for health officials to conduct a thorough policy review from a public health perspective, using as a model the World Health Organization’s global strategy to reduce the harmful use of alcohol.

Background Excess alcohol consumption has serious adverse effects on health and violence-related harm. In the UK around 37% of men and 29% of women drink to excess and 20% and 13% report binge drinking. The potential impact on population health from a reduction in consumption is considerable. One proposed method to reduce consumption is to reduce availability through controls on alcohol outlet density. In this study we investigate the impact of a change in the density of alcohol outlets on alcohol consumption and alcohol-related harms to health in the community. Methods/Design A natural experiment of the effect of change in outlet density between 2005–09, in Wales, UK; population 2.4 million aged 16 years and over. Data on outlets are held by the 22 local authorities in Wales under The Licensing Act 2003. The study outcomes are change in (1) alcohol consumption using data from annual Welsh Health Surveys, (2) alcohol-related hospital admissions using the Patient Episode Database for Wales, (3) Accident & Emergency department attendances between midnight–6am, and (4) alcohol-related violent crime against the person, using Police data. The data will be anonymously record-linked within the Secure Anonymised Information Linkage Databank at individual and 2001 Census Lower Super Output Area levels. New methods of network analysis will be used to estimate outlet density. Longitudinal statistical analysis will use (1) multilevel ordinal models of consumption and logistic models of admissions and Accident & Emergency attendance as a function of change in individual outlet exposure, adjusting for confounding variables, and (2) spatial models of the change in counts/rates of each outcome measure and outlet density. We will assess the impact on health inequalities and will correct for population migration. Discussion This inter-disciplinary study requires expertise in epidemiology and public health, health informatics, medical statistics, geographical information science

The occurrence of more than 200 diseases, including cancer, can be attributed to alcohol drinking. The global cancer deaths attributed to alcohol-consumption rose from 243,000 in 1990 to 337,400 in 2010. In 2010, cancer deaths due to alcohol consumption accounted for 4.2% of all cancer deaths. Strong epidemiological evidence has established the causal role of alcohol in the development of various cancers, including esophageal cancer, head and neck cancer, liver cancer, breast cancer, and colorectal cancer. The evidence for the association between alcohol and other cancers is inconclusive. Because of the high prevalence of ALDH2*2 allele among East Asian populations, East Asians may be more susceptible to the carcinogenic effect of alcohol, with most evidence coming from studies of esophageal cancer and head and neck cancer, while data for other cancers are more limited. The high prevalence of ALDH2*2 allele in East Asian populations may have important public health implications and may be utilized to reduce the occurrence of alcohol-related cancers among East Asians, including: 1) Identification of individuals at high risk of developing alcohol-related cancers by screening for ALDH2 polymorphism; 2) Incorporation of ALDH2 polymorphism screening into behavioral intervention program for promoting alcohol abstinence or reducing alcohol consumption; 3) Using ALDH2 polymorphism as a prognostic indicator for alcohol-related cancers; 4) Targeting ALDH2 for chemoprevention; and 5) Setting guidelines for alcohol consumption among ALDH2 deficient individuals. Future studies should evaluate whether these strategies are effective for preventing the occurrence of alcohol-related cancers.

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.

Curiosity, composed of two factors: exploration and absorption, has been previously associated with life satisfaction, life meaningfulness, and enhanced positive affect. It also shares some overlap with sensation seeking, which has been linked to alcohol use and other addictive behaviors. The present research explored the association between curiosity and college women's problematic drinking in the context of sensation seeking. Participants (79 women) completed questionnaires measuring curiosity, sensation seeking, alcohol consumption, and consequences related to alcohol consumption. A zero-inflated negative binomial model indicated that curiosity and sensation seeking accounted for unique variance in alcohol-related problems after controlling for drinking. The curiosity factors had opposing relationships to alcohol-related problems: higher scores on absorption were associated with more alcohol-related problems whereas higher scores on exploration were associated with fewer alcohol-related problems. Should findings be replicated, the curiosity factors may represent additional prevention and intervention targets. Future directions for research about curiosity and drinking and for the inclusion of positive psychology constructs in addictive behaviors research are discussed.

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.

Alcohol-related violence is a serious and common social problem. Moreover, violent behaviour is much more common in alcohol-dependent individuals. Animal experiments and human studies have provided insights into the acute effect of alcohol on aggressive behaviour and into common factors underlying acute and chronic alcohol intake and aggression. These studies have shown that environmental factors, such as early-life stress, interact with genetic variations in serotonin-related genes that affect serotonergic and GABAergic neurotransmission. This leads to increased amygdala activity and impaired prefrontal function that, together, predispose to both increased alcohol intake and impulsive aggression. In addition, acute and chronic alcohol intake can further impair executive control and thereby facilitate aggressive behaviour.

Multiple alcohol control policies have been enacted since the early 1980s to keep drunk drivers off the roads and to prevent more alcohol-related traffic fatalities. In this paper, we analyze nine traffic policies to determine the extent to which each policy contributes to effective alcohol-related fatality prevention. Compared with the existing literature, this paper addresses a more comprehensive set of traffic policies. In addition, we used a panel GLS model that holds regional effects and state-specific time effects constant to analyze their impact on alcohol-related fatalities with two distinct rates: alcohol-related traffic deaths per capita and alcohol-related traffic deaths per total traffic deaths. While per capita alcohol-related traffic deaths is used more often in other studies, alcohol-related traffic deaths per total traffic deaths better reflects the impact of policies on deterring drunk driving. In addition, regional analyses were conducted to determine the policies that are more effective in certain regions. The findings of this study suggest that zero tolerance laws and increased beer taxes are the most effective policies in reducing alcohol-related fatalities in all regions.
Tourism and fatal single motor vehicle accidents, an index of alcohol-related motor accidents, are examined in a cross-sectional analysis of the 50 states of the Union and the District of Columbia. A multiple regression model is employed in which average mileage driven, percent of metropolitan residents, and number of licensed drivers are statistically controlled. Tourism is found to be positively associated with the single motor vehicle fatality rate. Further research and policy implications are discussed.

In Japan, per capita alcohol consumption increased sharply during the post World War II period followed by an increase in cirrhosis mortality. The prevalence of alcoholic cirrhosis among hospitalized patients also increased, from 11% in 1969 to 18% in 1985. Despite an increase in the percentage of drinkers among young women, over 80% of women in Japan are still abstainers or light drinkers. Thus, female cirrhosis mortality rates can be used as a proxy measure of non-alcohol-related cirrhosis mortality rates to estimate alcohol-related cirrhosis deaths among Japanese men. Employing this method, we conclude that two-thirds of cirrhosis deaths among men between 24 and 85 years of age and half of all cirrhosis deaths were attributable to alcohol. Two factors are probably responsible for the differences in proportional morbidity and proportional mortality of alcohol-related cirrhosis: differences in survival rates between alcoholic and non-alcoholic cirrhosis patients and detection bias toward post-hepatic cirrhosis. The synergistic effect of alcohol on viral hepatitis may in part explain excess cirrhosis deaths among Japanese men.

Objective Posttraumatic stress disorder (PTSD), alcohol use, and alcohol-related consequences have been linked to emotion dysregulation. Sex differences exist in both emotion regulation dimensions and alcohol use patterns. This investigation examined facets of emotion dysregulation as potential mediators of the relationship between PTSD symptoms and alcohol-related consequences and whether differences may exist across sexes. Methods Participants included 240 college students with a trauma history who reported using alcohol within the past three months and completed measures of PTSD symptoms, emotion dysregulation, alcohol consumption, alcohol-related consequences, and negative affect. The six facets of emotion dysregulation were examined as mediators of the relationship between PTSD symptoms and alcohol-related consequences in the full sample and by sex. Results There were differences in sexes on several variables, with women reporting higher PTSD scores and Lack of Emotional Awareness. Men reported significantly higher drinks per week in a typical week and a heavy week. There were significant associations between the variables for the full sample, with PTSD showing associations with five facets of emotion dysregulation subscales: Impulse Control Difficulties when Upset, Difficulties Engaging in Goal-Directed Behavior, Nonacceptance of Emotional Responses, Lack of Emotional Clarity, and Limited Access to Emotion Regulation Strategies. Alcohol-related consequences were associated with four aspects of emotion dysregulation: Impulse Control Difficulties when Upset, Difficulties Engaging in Goal-Direct Behavior, Nonacceptance of Emotional Reponses, and Limited Access to Emotion Regulation Strategies. Two aspects of emotion regulation, Impulse Control Difficulties and Difficulties Engaging in Goal Directed Behavior, mediated the relationship between PTSD symptoms and alcohol-related consequences in the full sample, even after adjusting for the effects of negative affect

Alcohol is the number three contributor to the burden of disease worldwide so must remain a priority health promotion issue internationally. Malaysia is a Muslim country and alcohol-related harm was not seen as a priority until recently, because it only affects a minority of the population. Sabah has more than 30 different ethnic groups, and alcohol has a traditional role in the cultural practices of many of these groups. In 2009, the Intervention Group for Alcohol Misuse (IGAM) was formed, under the umbrella of Mercy Malaysia by a group of healthcare workers, academics, members of the Clergy and people who were previously alcohol-dependent concerned about the harmful effects of excessive alcohol consumption. IGAM in collaboration with other bodies have organized public seminars, visited villages and schools, encouraged the formation of a support group and trained healthcare professionals in health promotion intervention. The focus later changed to empowering communities to find solutions to alcohol-related harm in their community in a way which is sensitive to their culture. A standard tool-kit was developed using WHO materials as a guide. Village committees were formed and adapted the toolkit according to their needs. This strategy has been shown to be effective, in that 90% of the 20 committees formed are actively and successfully involved in health promotion to reduce alcohol-related harm in their communities.

Introduction The aim of this work was to determine the effect of chronic alcohol exposure on peripheral nerves in a nutritionally balanced rat model of alcoholism. Methods Three different strains of adult male rats were pair-fed for 8 weeks with isocaloric liquid diets containing 0% or 37% ethanol. Nerve conduction studies (NCS) were performed. Peripheral nerve and muscle were examined histologically with morphometrics. Results Ethanol exposure significantly slowed velocity in tibial and fibular nerves, but not in the plantar nerve in all 3 strains. Studies of the sciatic nerve revealed decreased fiber diameters and increased regenerative sprouts in peripheral nerves. There was muscle denervation of ethanol-exposed rats in all 3 strains. Conclusions Chronic ethanol exposure caused a polyneuropathy characterized by axonal degeneration despite adequate nutrition. These results suggest that ethanol exposure has direct neurotoxic effects on peripheral nerves. This model may be useful in understanding the underlying mechanism(s) of alcohol-related peripheral neuropathy. PMID:23761140

Heterogeneity in the clinical symptoms of alcohol abuse was examined in 243 men and 305 women from families of hospitalized alcoholics, who had demonstrated different patterns of inheritance of susceptibility to alcoholism. Discriminant analysis was utilized to identify nine alcoholic symptoms that distinguished male relatives of alcoholic men from those of alcoholic women. Inability to abstain from alcohol, fighting and reckless driving while intoxicated, and alcohol treatment other than Alcoholics Anonymous were more prevalent in families of male probands. Male relatives of female probands experienced later onset of loss of control over drinking associated with benders, and cirrhosis and feelings of guilt. Female relatives of alcoholic men and women showed a marked predominance of the latter (Type 1) features, whereas male relatives had different clinical features, depending on the associated mode of inheritance.

Rationale Poor behavioral control and heightened attentional bias toward alcohol-related stimuli have independently received considerable attention in regard to their roles in alcohol abuse. Theoretical accounts have begun to speculate as to potential reciprocal interactions between these two mechanisms that might promote excessive alcohol consumption, yet experimental evidence is lacking. Objectives The objective of the study was to integrate these two lines of research through the development of a novel laboratory task that examines the degree to which alcohol cues serve to disrupt mechanisms of behavioral control. Methods Fifty adult drinkers were recruited to perform the attentional bias–behavioral activation (ABBA) task. The ABBA task, an adaptation of traditional cued go/no-go tasks, is a reaction time model that measures the degree to which alcohol-related stimuli can increase behavioral activation of a drinker and reduce the ability to inhibit inappropriate responses. Participants also completed a novel measure of attentional bias, the scene inspection paradigm (SIP), that measures fixation time on alcohol content imbedded in complex scenes. Results As hypothesized, the proportion of inhibitory failures on the ABBA task was significantly higher following alcohol images compared to neutral images. Correlational analyses showed that heightened attentional bias on the SIP was associated with greater response activation following alcohol images on the ABBA task. Conclusions These findings suggest that alcohol stimuli serve to disrupt mechanisms of behavioral control, and that heightened attentional bias is associated with greater disruption of control mechanisms following alcohol images.

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.

The aim of the present study was to examine spirituality, religiosity, and alcohol-related beliefs among college students. The sample consisted of 236 college students - 120 girls and 116 boys. The age range of the sample was between 18 and 21 years. The tools used in the study were Personal Information Data Sheet, Scale for Assessment of Attitudes toward Drinking and Alcoholism (SAADA), Alcohol Expectancy Questionnaire - Adult Form (AEQ), Beliefs and Values Scale (BVS), and The Religious Background and Behavior Questionnaire (RBBQ). The data were analyzed using t-test and Pearson's product moment correlation. Higher spirituality, religiosity, and both the components of religiosity - God Consciousness and Formal Practices, were all associated with less acceptance of drinking and alcoholism. Positive affect and higher spirituality were both associated with religiosity as well as its components. A positive correlation was found among religiosity and both its components. The results revealed gender differences in that the God Consciousness component of religiosity was found to be higher in girls, but not boys, who did not have exposure to alcohol through prior use or alcohol use in family. The implications for primary prevention for college students are discussed.

This paper describes general practitioners' (GPs) experiences of detecting and managing alcohol and alcohol-related problems in consultations. We undertook qualitative research in two phases in the North-East of England. Initially, qualitative interviews with 29 GPs explored their everyday work with patients with alcohol-related issues. We then undertook group interviews--two with GPs and one with a primary care team--where they discussed and challenged findings of the interviews. The GPs reported routinely discussing alcohol with patients with a range of alcohol-related problems. GPs believed that this work is important, but felt that until patients were willing to accept that their alcohol consumption was problematic they could achieve very little. They tentatively introduced alcohol as a potential problem, re-introduced the topic periodically, and then waited until the patient decided to change their behaviour. They were aware that they could identify and manage more patients. A lack of time and having to work with the multiple problems that patients brought to consultations were the main factors that stopped GPs managing more risky drinkers. Centrally, we compared the results of our study with [Thom, B., & Tellez, C. (1986). A difficult business-Detecting and managing alcohol-problems in general-practice. British Journal of Addiction, 81, 405-418] seminal study that was undertaken 20 years ago. We show how the intellectual, moral, emotional and practical difficulties that GPs currently face are quite similar to those faced by GPs from 20 years ago. As the definition of what could constitute abnormal alcohol consumption has expanded, so the range of consultations that they may have to negotiate these difficulties in has also expanded.

Perceived drinking norms have received increased attention as one determinant of high levels of college alcohol consumption and alcohol-related problems. Excessive drinking is widely visible on college campuses, and students may therefore assume that it is peer-supported (Kitts, 2003). Research into peer relations indicates that the perceived approval of important others predicts drinking behavior (Neighbors et al., 2007). Neither the use of alcohol-related protective behavioral strategies nor alcohol-related negative consequences have been investigated in terms of their perceived approval. The purpose of this study was to extend previous research on injunctive norms and assess self-other discrepancies in levels of approval for campus drinking patterns, negative alcohol-related consequences, and protective behavioral strategies. Undergraduate volunteers (n = 324, 61% female, 67% Caucasian) completed an online survey of drinking patterns; they rated comfort with overall campus drinking, and the acceptability of alcohol-related consequences and protective strategies for themselves and their close friends. As predicted, students expressed lower acceptance of consequences than their friends, and higher acceptance of alcohol-related protective strategies. We observed main effects of gender and year in school. Males and upperclassmen expressed higher acceptance of negative consequences for both self and others, and lower acceptance of protective strategies for both self and others. Implications for prevention programs are discussed. PMID:21236586

Alcoholism is a severe disorder that affects the functionality of neurons in the central nervous system (CNS) and alters the behavior of the affected person. Electroencephalogram (EEG) signals can be used as a diagnostic tool in the evaluation of subjects with alcoholism. The neurophysiological interpretation of EEG signals in persons with alcoholism (PWA) is based on observation and interpretation of the frequency and power in their EEGs compared to EEG signals from persons without alcoholism. This paper presents a review of the known features of EEGs obtained from PWA and proposes that the impact of alcoholism on the brain can be determined by computer-aided analysis of EEGs through extracting the minute variations in the EEG signals that can differentiate the EEGs of PWA from those of nonaffected persons. The authors advance the idea of automated computer-aided diagnosis (CAD) of alcoholism by employing the EEG signals. This is achieved through judicious combination of signal processing techniques such as wavelet, nonlinear dynamics, and chaos theory and pattern recognition and classification techniques. A CAD system is cost-effective and efficient and can be used as a decision support system by physicians in the diagnosis and treatment of alcoholism especially those who do not specialize in alcoholism or neurophysiology. It can also be of great value to rehabilitation centers to assess PWA over time and to monitor the impact of treatment aimed at minimizing or reversing the effects of the disease on the brain. A CAD system can be used to determine the extent of alcoholism-related changes in EEG signals (low, medium, high) and the effectiveness of therapeutic plans.

Background Alcohol-related peripheral neuropathy (ALN) is generally characterized as an axonal large-fiber polyneuropathy caused by thiamine deficiency. We hypothesized, based on clinical observations, that ALN is associated with a small-fiber polyneuropathy that can be diagnosed with skin biopsy in heavy alcohol drinking subjects with normal thiamine status. Methods Eighteen individuals (9 heavy alcohol drinking subjects and 9 healthy control subjects) were assessed for the potential utility of skin biopsies in detecting ALN-associated small nerve fiber degeneration. Heavy drinking was defined as greater than 4 drinks/d and 5 drinks/d in women and men, respectively, as determined by the Timeline Follow-Back and lifetime drinking history. All subjects underwent neurological examination, nerve conduction studies, and skin biopsies to quantify end nerve fiber densities (ENFD). Other causes of neuropathy were excluded and thiamine status was assessed. Results Average ENFD were significantly decreased at the calf in the alcohol group as compared with control group (p < 0.0001). Histological sections demonstrated striking attrition and architectural simplification of intraepidermal nerve fibers in the heavy alcohol drinking subjects. There were no significant intergroup differences with respect to clinical assessments of neuropathy or thiamine status. Conclusions ALN is associated with a small-fiber neuropathy that can be detected with skin biopsy in heavy alcohol drinking individuals with normal thiamine status. Skin biopsy is a useful, minimally invasive biomarker that could extend studies to understand the effect of alcohol on the peripheral nerves and to evaluate potential therapeutic agents in larger clinical trials.

Introduction It is well established that individuals exposed to alcohol in utero have reduced cortical grey matter volumes. However, the candidate determinants of these reductions, cortical thickness (CT) and surface area (SA), have not been investigated exclusively in alcohol-related neurodevelopmental disorder (ARND), the most prevalent fetal alcohol spectrum disorder subgroup that lacks the characteristic facial dysmorphology. Methods T1-weighted magnetic resonance imaging scans were obtained from 88 participants (8–16 years), 36 diagnosed with ARND and 52 typically developing controls. Scans were submitted to the CIVET pipeline (version 1.1.10). Deformable models were used to construct the inner white matter surfaces and pial surfaces from which CT and SA measures were derived. Group differences in cortical volume, CT, and SA were computed using a general linear model covaried for age, sex, and handedness. Results Global cortical volume reductions in ARND did not reflect CT, which did not differ between groups. Instead, volume decreases were consistent with global SA reductions in bilateral frontal and temporal as well as right occipital regions. Local reductions in SA were observed in the right superior temporal gyrus and the right occipital-temporal region. Conclusion Results suggest that in ARND, prenatal alcohol exposure perturbs global SA to a greater degree than CT, particularly in the right temporal lobe. PMID:24653953

Alcohol-related violence, a longstanding, serious, and pervasive social problem, has provided researchers from diverse disciplines with a model to study individual differences in aggressive and violent behavior. Of course, not all alcohol consumers will become aggressive after drinking and similarly, not all individuals with alcohol use disorders will exhibit such untoward behavior. Rather, the relationship is best conceptualized as complex and indirect and is influenced by a constellation of social, cognitive, and biological factors that differ greatly from one person to the next. Animal experiments and human studies have elucidated how these mechanisms and processes explain (i.e., mediate) the relation between acute and chronic alcohol consumption and aggressive behavior. Further, the rich body of literature on alcohol-related aggression has allowed for identification of several potential high-yield targets for clinical intervention, e.g., cognitive training for executive dysfunction; psychopharmacology targeting affect and threat perception, which may also generalize to other psychiatric conditions characterized by aggressive behavior. Here we aim to integrate pertinent findings, derived from different methodological approaches and theoretical models, which explain heterogeneity in aggressive responses to alcohol. A translational platform is provided, highlighting common factors linking alcohol and aggression that warrant further, interdisciplinary study in order to reduce the devastating social impact of this phenomenon.

This study examined the relationship between patron demographics, substance use, and experience of recent alcohol-related accidents and injuries that were not due to interpersonal violence in night-time entertainment districts. Cross-sectional interviews (n = 4016) were conducted around licensed venues in entertainment districts of five Australian cities. Demographic factors associated with non-violent alcohol-related injuries were examined, including gender, age, and occupation. The association between substance use on the night of interview; blood alcohol concentration (BAC), pre-drinking, energy drink consumption, and illicit drug use; and experience of injury was also explored. Thirteen percent of participants reported an alcohol-related injury within the past three months. Respondents aged younger than 25 years were significantly more likely to report an alcohol-related injury. Further, a significant occupation effect was found indicating the rate of alcohol-related injury was lower in managers/professionals compared to non-office workers. The likelihood of prior alcohol-related injury significantly increased with BAC, and self-reported pre-drinking, energy drink, or illicit drug consumption on the night of interview. These findings provide an indication of the demographic and substance use-related associations with alcohol-related injuries and, therefore, potential avenues of population-level policy intervention. Policy responses to alcohol-related harm must also account for an assessment and costing of non-violent injuries. PMID:28085105

This paper investigates the relationship between community off-sales premises and alcohol-related detritus (litter/remains) in residential neighbourhoods. This was accomplished by photographing all brand-identifiable alcohol product detritus (glass, packaging, etc.) where they lay and mapping these against the presence of off-sales outlets (licensed convenience stores) in the community. It was hypothesised that alcohol-related detritus would be greatest near to such alcohol outlets. However, although there was some evidence of a "broken bottles effect", accumulations of alcohol-related detritus near some off-sales premises, it is concluded that local area deprivation is a better predictor of such alcohol-related incivility than is outlet provision. The implications of these findings are discussed in relation to current social responsibility policy developments which are designed to make the alcohol industry liable for alcohol-related incivilities.

Human studies have found alcoholics to have a smaller brain size than moderate drinkers; however, these studies are complicated by many uncontrollable factors, including timing and amount of alcohol use. Animal experiments, which can control many factors, have established that alcohol can cause damage to brain cells (i.e., neurons), which results in their loss of structure or function (i.e., neurodegeneration) in multiple brain regions, similar to the damage found in human alcoholics. In addition, animal studies indicate that inhibition of the creation of neurons (i.e., neurogenesis) and other brain-cell genesis contributes to alcoholic neurodegeneration. Animal studies also suggest that neurodegeneration changes cognition, contributing to alcohol use disorders. Risk factors such as adolescent age and genetic predisposition toward alcohol consumption worsen neurodegeneration. Mild impairment of executive functions similar to that found in humans occurs in animals following binge alcohol treatment. Thus, animal studies suggest that heavy alcohol use contributes to neurodegeneration and the progressive loss of control over drinking. Despite the negative consequences of heavy drinking, there is hope of recovery with abstinence, which in animal models can result in neural stem-cell proliferation and the formation of new neurons and other brain cells, indicative of brain growth.

The present study applied the Go/No-Go Association Test (GNAT; Nosek & Banaji, 2001) to measure alcohol-related implicit cognitions. Additionally, it assessed the role of implicit cognitions as a potential moderator in the relationship between explicit predictors of alcohol use and hazardous drinking behavior. University undergraduate students (N = 214) completed self-report questionnaires assessing reasons for drinking and reported alcohol use. Participants also completed two GNATs assessing implicit-alcohol-related cognitions associated with attitude (good-bad) and perceived safety (safe-dangerous). As expected, participants held implicit appraisals of alcohol as ‘‘bad’’ and ‘‘dangerous’’ in the context of nonalcoholic drinks, and as ‘‘good’’ and ‘‘safe’’ in the context of licit and illicit drugs. Implicit alcohol-related cognitions moderated the relationship between drinking to cope with negative affect and hazardous drinking and drinking due to cues or craving and hazardous drinking. These findings highlight the multidimensional nature of implicit cognitions and the role of negative implicit alcohol-related associations in moderating relationships between explicit processes and subsequent alcohol use behaviors.

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.

Posttraumatic stress disorder (PTSD) represents a debilitating psychiatric condition that is affecting the lives of many returning veterans. PTSD and alcohol use and dependence are highly comorbid. The purpose of this study was to understand the functional mechanisms between PTSD and alcohol use and problems. Specifically, the role of negative urgency and emotional intelligence were investigated as vulnerability and resiliency factors, respectively. This study utilized experience sampling to test associations between PTSD symptoms and alcohol use and related problems in a sample of 90 OIF/OEF veterans. Participants completed eight brief questionnaires daily for two weeks on palmtop computers. Elevations in PTSD symptoms during the day were associated with subsequent increases in alcohol use and associated problems that night. PTSD symptoms were associated with greater problems above and beyond the effect of drinking level at both the within- and between- person level. Emotional intelligence was associated with lower negative urgency, fewer PTSD symptoms, and less alcohol use and associated problems. The effects of emotional intelligence were primarily indirect via negative urgency and the effects of negative urgency on alcohol use and problems were indirect via its positive association with PTSD symptoms. Hypothesized cross-level effects of emotional intelligence and negative urgency were not supported. The findings suggest a functional association between PTSD symptoms and alcohol consumption. The association between PTSD symptoms and alcohol consumption is consistent with a self-medication model. However, the significant associations between PTSD symptoms and alcohol problems, after controlling for use level, suggest a broader role of dysregulation. PMID:25134021

Abstract Alcohol misuse among adolescents is a common issue worldwide and is an emerging problem in China. This study aimed to investigate the prevalence of alcohol drinking and alcohol-related problems among Chinese adolescents and to explore their risk factors and connections. A cross-sectional study using an anonymous questionnaire was conducted among junior and senior high school students between 2010 and 2012. Data on self-reported alcohol use, alcohol-related problems, school factors, family factors, and psychosocial factors were collected. Descriptive analyses were made of the proportions of sociodemographics, family, school, and psychosocial factors. Multilevel logistic regression models were conducted to analyze the risk factors for alcohol drinking and alcohol-related problems. Of the 105,752 students who ranged in age from 9 to 21 years, the prevalence of current drinking among students was 7.3%, and 13.2% students reported having alcohol-related problems. Male students were 1.78 (95% confidence interval [CI] = 1.69–1.87) times more likely to be involved in current drinking and 1.86 (95% CI = 1.79–1.93) times more likely to have alcohol-related problems. Higher grade level students were at a higher risk of current drinking (adjusted odds ratio [AOR] = 1.09, 95% CI = 1.05–1.13) and having alcohol-related problems (AOR = 1.43, 95% CI = 1.42–1.58). Older students were more likely to report current drinking (AOR = 1.06, 95% CI = 1.04–1.17) and having alcohol-related problems (AOR = 1.83, 95% CI = 1.82–1.85). Having poor classmate relations (AOR = 1.28, 95% CI = 1.03–1.37), having poor relationships with teachers (AOR = 1.08, 95% CI = 1.00–1.16), and below average academic achievement (AOR = 1.50, 95% CI = 1.41–1.59) were positively associated with current drinking. Moreover, students with suicidal ideation were at a higher risk of current drinking (AOR = 1.70, 95% CI = 1.61–1.81) and having alcohol-related problems (AOR = 2.08, 95% CI = 1

Alcohol consumption is common across subpopulations in the United States. However, the health burden associated with alcohol consumption varies across groups, including those defined by demographic characteristics such as age, race/ethnicity, and gender. Large national surveys, such as the National Epidemiologic Survey on Alcohol and Related Conditions and the National Survey on Drug Use and Health, found that young adults ages 18–25 were at particularly high risk of alcohol use disorder and unintentional injury caused by drinking. These surveys furthermore identified significant variability in alcohol consumption and its consequences among racial/ethnic groups. White respondents reported the highest prevalence of current alcohol consumption, whereas alcohol abuse and dependence were most prevalent among Native Americans. Native Americans and Blacks also were most vulnerable to alcohol-related health consequences. Even within ethnic groups, there was variability between and among different subpopulations. With respect to gender, men reported more alcohol consumption and binge drinking than women, especially in older cohorts. Men also were at greater risk of alcohol abuse and dependence, liver cirrhosis, homicide after alcohol consumption, and drinking and driving. Systematic identification and measurement of the variability across demographics will guide prevention and intervention efforts, as well as future research. PMID:27159807

This paper investigates the role of race/ethnicity, language skills (a proxy for acculturation among Hispanics in Arizona, California, New Mexico, and Texas), income, and education level on alcohol-related fatal motor vehicle crashes. Using the Fatality Analysis Reporting System (FARS), we confirmed previous state-based studies showing that high income and education levels have a protective influence on alcohol-related fatal motor vehicle crashes. We also confirmed that language proficiency/acculturation tends to increase the vulnerability of Hispanic women to alcohol-related fatalities. Differences in alcohol-related fatality rates across Hispanic subgroups are observed. Future reductions in alcohol-related traffic fatalities may require prevention policies that take into account existent variations in acculturation, income, and education among racial/ethnic groups and subgroups.

The purpose of this study was to examine the effect of environmental contexts on alcohol norms, expectancies, and efficacy ratings. University students (n = 177) recruited via opportunity sampling completed questionnaires in either university lecture theaters or in a student bar. Positive social, fun, and tension reduction outcome expectancies were higher and social drink refusal self efficacy was lower in those participants questioned in a student bar relative to those questioned in a university lecture theater. These differences were found while controlling for between-groups variations in typical alcohol consumption quantities. Although hitherto largely unexamined by research, context appears to be a potentially important moderator of alcohol-related cognitions. Such findings require further exploration to inform more effective intervention approaches and have implications for the validity of existing literature.

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

Analysis of the impact of alcohol as an underlying and non-underlying cause of death in Wisconsin showed a marked increase between 1963 and 1977 in the frequency of deaths reported with mention of alcohol. The rate of deaths for which alcohol was a non-underlying cause rose more sharply during this period (2.4 per 100,000 to 9.3) than that of alcohol-related causes (4.6/100,000 to 9.0). Nearly 90 per cent of alcohol-related deaths at ages 15-24 reported alcohol as a non-underlying cause, compared to 40.7 per cent at ages 45-54 and 57 per cent at ages 75+. This proportion was higher (50.8 per cent) among males than among females (32.8 per cent). Deaths related to alcohol are attributed to a number of underlying causes in addition to alcohol. In 1975-77, nearly half of the reported alcohol-related deaths were attributed to other causes, including accidents (14.8 per cent), heart disease (14.3 per cent), respiratory diseases (4.9 per cent), suicide (3.7 per cent), and cancer (31 per cent). These percentages may reflect substantial underreporting. Comparison of motor vehicle driver death certificates with blood alcohol test reports for these drivers shows 90 per cent underreporting of alcohol on death certificates. This fact, along with other information on underreporting, shows that the approximately 650 deaths now being reported with mention of alcohol annually in Wisconsin, represent only a portion of such deaths.

Veterans returning from Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) have been found to be at increased risk for post-traumatic stress disorder (PTSD) and alcohol use disorders, leading to negative mental health-related quality of life (MHRQoL). The current study examined the unique impact of alcohol consumption levels versus alcohol-related consequences on the relationship between PTSD symptoms and MHRQoL in a sample of OEF/OIF combat veterans (N = 205, median age 29, 95% men). Mediation analyses indicated that the effect of PTSD symptoms on MHRQoL was explained only by alcohol-related consequences and not by alcohol consumption. Findings highlight the importance of including alcohol-related consequences in clinical assessment and intervention programs for OEF/OIF veterans. Additionally, this study enhances knowledge regarding the underlying mechanisms of functional impairment related to PTSD and alcohol use disorders.
Background Inpatient care for alcohol intoxication is increasing in Sweden, especially among young women. Since it is well known that alcohol disorder is a chronic relapsing illness, this study examines the extent to which people return for more care. Method All inpatients with alcohol-related diagnoses in Stockholm County during 1997 were followed prospectively to 2007 through registers. The proportion reappearing for the same diagnosis, other alcohol-related inpatient, or outpatient care each year after baseline, as well as the number of years the inpatients reappeared were calculated (n = 2735). Three diagnoses were examined separately; alcohol dependence, harmful use of alcohol, and alcohol intoxication. Results Three out of five inpatients with an alcohol diagnoses reappeared for more alcohol-related inpatient care during the following decade. The proportion returning was largest the year after baseline and then decreased curvilinearly over time. The inclusion of outpatient care increased proportions, but did not change patterns. Of those with an alcohol dependence diagnosis at baseline 42 percent returned for more alcohol-related inpatient care the first, 28 percent the fifth, and 25 percent the tenth year. Corresponding proportions for harmful use and intoxication were smaller. One in five among those with an alcohol dependence returned for more than five of the ten years. Ordered logistic regressions confirmed that besides diagnosis, age and gender were independently related to the number of years returning to care. Conclusions While middle-aged males with alcohol dependence were in a revolving door, young female inpatients with intoxication diagnosis returned to a comparably lower degree. PMID:21771291
Background Although there have been a wide range of epidemiological studies examining the impact of patterns of alcohol consumption among adolescents, there remains considerable variability in both defining these patterns and the ability to comprehensively evaluate their relationship to behavioural patterns. This study explores a new procedure for defining and evaluating drinking patterns and integrating well-established indicators. The composite measure is then used to estimate the impact of these patterns on alcohol-related aggressive behaviour among Italian adolescents. Methods Data were collected as part of the 2011 European School Survey Project on Alcohol and other Drugs (ESPAD). A national sample of 14,199 students aged 15–19 years was collected using an anonymous, self-administered questionnaire completed in a classroom setting. Drinking patterns were established using principal component analysis. Alcohol-related aggression was analysed as to its relationship to patterns of drinking, behaviour of friends towards alcohol use, substance use/abuse, school performance, family relationships and leisure activities. Results Several specific drinking patterns were identified: “Drinking to Excess” (DE), “Drinking with Intoxication” (DI) and “Drinking but Not to Excess” (DNE). A higher percentage of males were involved in alcohol-related aggression compared with females. In males, the DE and DI patterns significantly increased the likelihood of alcohol-related aggression, whereas the DNE pattern was negatively associated. Similar results were found in females, although the DI pattern was not significantly associated with alcohol-related aggression. Overall, cigarette smoking, illegal drug use, truancy, limited parental monitoring, frequent evenings spent outside of the home and peer influence associated strongly with alcohol-related aggression. Conclusions Our findings suggest that drinking patterns, as uniquely monitored with an integrated metric

Although there are wide differences in alcohol use patterns among countries, men are consistently more likely than women to be drinkers and to drink heavily. Studies of alcohol use among sexual minorities (SMs), however, reflect a more complex picture. Such research has found higher rates of alcohol use and alcohol-related problems among SM persons than among heterosexuals and greater differences between SM and heterosexual women than between SM and heterosexual men. A variety of factors may contribute to differences in alcohol use and alcohol-related problems between men and women and between SM and heterosexual people. An improved understanding of these factors is important to guide prevention and treatment efforts. Although there is a dearth of literature on use of alcohol by SMs in many parts of the world, especially lower- and middle-income countries, we attempt to review and integrate the sparse data that are available from these lower-resourced countries. The global perspective presented in this article is the first attempt to go beyond a general review of literature in the Western world to document the gender paradox in alcohol use among heterosexuals and SMs in diverse countries worldwide.

Studies of visual attention find that drinkers spend more time attending to images of alcohol-related stimuli compared to neutral images. It is believed that this attentional bias contributes to the maintenance of alcohol use. However, no research has examined the possibility that this bias of visual attention might actually impede the functioning of other modalities, such as the processing of accompanying auditory stimuli. This study aimed to determine if alcohol-related images engender greater sensory dominance than neutral images, such that processing accompanying information from another modality (audition) would be impeded. Drinkers who had an attentional bias to alcohol-related images performed a multisensory perception task that measured how alcohol-related versus neutral visual images affected their ability to detect and respond to simultaneously presented auditory signals. In accord with the hypothesis, compared with neutral images, the presentation of alcohol-related images impaired the ability to detect and respond to auditory signals. Increased dominance of the visual modality was demonstrated by more bimodal targets being misclassified as visual-only targets in the alcohol target condition compared with that of the neutral. Findings suggest that increased processing of alcohol-related stimuli may impede an individual's ability to encode and interpret information obtained from other sensory modalities.

There are important individual differences in acute subjective responses to alcohol, which have often been assessed using self-report measures. There is also evidence of meaningful between-persons variation in alcohol’s disinhibiting effects on behavior, such that some individuals become more impaired on tasks of inhibition than do others after an intoxicating dose. The degree to which subjective alcohol responses correspond with these disinhibition effects is not yet clear. In this study, we tested associations among indices of subjective alcohol responses and their correspondence with sensitivity to alcohol-related disinhibition. We recruited recent-binge-drinking emerging adults (N = 82) for a group-administered, placebo-controlled, within-subject, counterbalanced alcohol challenge in a simulated bar laboratory. Confirmatory factor analyses revealed that a two factor model with several cross-loadings explained associations among the subjective measures well, replicating a differentiation between stimulant-like and sedative-like subjective responses. Controlling sex and placebo performance, participants who reported greater subjective stimulant-like effects—but not sedative-like effects—experienced more alcohol-related disinhibition, as measured by Cued Go/No-Go Task inhibitory failures. This association was small-to-moderate in magnitude. The results of this study highlight the distinction between stimulant-like and sedative-like subjective alcohol effects. They suggest, additionally, that there may be modest commonalities between alcohol’s acute impacts on subjective stimulation and objective disinhibition. PMID:26867000

Treatment programmes specifically for women offenders are under-developed. A systematic review of studies that could inform interventions for alcohol-related offending by women is reported. Three questions were addressed: 1) What is the most up to date knowledge of 'what works' with females who commit alcohol-related offences? 2) What are the identifiable risk-needs factors for non-alcohol dependent women who commit offences involving alcohol misuse? 3) Are there differences between male and female alcohol-related offending? Four studies addressed the effectiveness of psychosocial interventions; three addressed identifiable risk-needs; and 19 addressed differences between male and female offenders' alcohol-related offending. Heterogeneity of these studies precluded meta-analyses, and so a narrative synthesis method was used. There is insufficient evidence to answer the question of what treatment works with women who commit alcohol-related offences. Drunk-driving is most widely studied, and women offenders appear to have more psychosocial problems than men. Alcohol increases the likelihood of violence for both men and women, and, while the mechanisms whereby alcohol increases the likelihood of violence are likely the same in men and women, the effect may be moderated by gender-associated issues. Again, women offenders appear to have more psychosocial problems than men. Implications for developing interventions are discussed.

Aims Epidemiological surveys over the last 20 years show a steady increase in the amount of alcohol consumed by older age groups. Physiological changes and an increased likelihood of health problems and medication use make older people more likely than younger age groups to suffer negative consequences of alcohol consumption, often at lower levels. However, health services targeting excessive drinking tend to be aimed at younger age groups. The aim of this study was to gain an in-depth understanding of experiences of, and attitudes towards, support for alcohol related health issues in people aged 50 and over. Methods Qualitative interviews (n = 24, 12 male/12 female, ages 51–90 years) and focus groups (n = 27, 6 male/21 female, ages 50–95 years) were carried out with a purposive sample of participants who consumed alcohol or had been dependent. Findings Participants’ alcohol misuse was often covert, isolated and carefully regulated. Participants tended to look first to their General Practitioner for help with alcohol. Detoxification courses had been found effective for dependent participants but only in the short term; rehabilitation facilities were appreciated but seen as difficult to access. Activities, informal groups and drop-in centres were endorsed. It was seen as difficult to secure treatment for alcohol and mental health problems together. Barriers to seeking help included functioning at a high level, concern about losing positive aspects of drinking, perceived stigma, service orientation to younger people, and fatalistic attitudes to help-seeking. Facilitators included concern about risk of fatal illness or pressure from significant people. Conclusion Primary care professionals need training on improving the detection and treatment of alcohol problems among older people. There is also a compelling need to ensure that aftercare is in place to prevent relapse. Strong preferences were expressed for support to be provided by those who had experienced

Objective: This study investigated whether self-reports of alcohol-related postings on Facebook by oneself or one’s Facebook friends were related to common motives for drinking and were uniquely predictive of self-reported alcohol outcomes (alcohol consumption, problems, and cravings). Method: Pacific Northwest undergraduates completed a survey of alcohol outcomes, drinking motives, and alcoholrelated Facebook postings. Participants completed the survey online as part of a larger study on alcohol use and cognitive associations. Participants were randomly selected through the university registrar’s office and consisted of 1,106 undergraduates (449 men, 654 women, 2 transgender, 1 declined to answer) between the ages of 18 and 25 years (M = 20.40, SD = 1.60) at a large university in the Pacific Northwest. Seven participants were excluded from analyses because of missing or suspect data. Results: Alcohol-related postings on Facebook were significantly correlated with social, enhancement, conformity, and coping motives for drinking (all ps < .001). After drinking motives were controlled for, self–alcohol-related postings independently and positively predicted the number of drinks per week, alcohol-related problems, risk of alcohol use disorders, and alcohol cravings (all ps < .001). In contrast, friends’ alcohol-related postings only predicted the risk of alcohol use disorders (p < .05) and marginally predicted alcohol-related problems (p = .07). Conclusions: Posting alcohol-related content on social media platforms such as Facebook is associated with common motivations for drinking and is, in itself, a strong predictive indicator of drinking outcomes independent of drinking motives. Moreover, self-related posting activity appears to be more predictive than Facebook friends’ activity. These findings suggest that social media platforms may be a useful target for future preventative and intervention efforts. PMID:24766750
The goal of this study was to describe how activists engaged in campaigns to change alcohol policies in inner city areas framed alcohol problems, and whether or not their frameworks reflected major models used in the field, such as the alcoholism as a disease model, an alcohol problems perspective, or a public health approach to alcohol problems. The findings showed that activists’ models shared some aspects with dominant approaches which tend to focus on individuals and to a lesser extent on regulating alcohol marketing and sales. However, activists’ models differed in significant ways by focusing on community level problems with alcohol; on problems with social norms regarding alcohol use; and on the relationship of alcohol use to illicit drugs.

Background Socioeconomic inequalities in alcohol-related mortality have been documented in several European countries, but it is unknown whether the magnitude of these inequalities differs between countries and whether these inequalities increase or decrease over time. Methods and Findings We collected and harmonized data on mortality from four alcohol-related causes (alcoholic psychosis, dependence, and abuse; alcoholic cardiomyopathy; alcoholic liver cirrhosis; and accidental poisoning by alcohol) by age, sex, education level, and occupational class in 20 European populations from 17 different countries, both for a recent period and for previous points in time, using data from mortality registers. Mortality was age-standardized using the European Standard Population, and measures for both relative and absolute inequality between low and high socioeconomic groups (as measured by educational level and occupational class) were calculated. Rates of alcohol-related mortality are higher in lower educational and occupational groups in all countries. Both relative and absolute inequalities are largest in Eastern Europe, and Finland and Denmark also have very large absolute inequalities in alcohol-related mortality. For example, for educational inequality among Finnish men, the relative index of inequality is 3.6 (95% CI 3.3–4.0) and the slope index of inequality is 112.5 (95% CI 106.2–118.8) deaths per 100,000 person-years. Over time, the relative inequality in alcohol-related mortality has increased in many countries, but the main change is a strong rise of absolute inequality in several countries in Eastern Europe (Hungary, Lithuania, Estonia) and Northern Europe (Finland, Denmark) because of a rapid rise in alcohol-related mortality in lower socioeconomic groups. In some of these countries, alcohol-related causes now account for 10% or more of the socioeconomic inequality in total mortality. Because our study relies on routinely collected underlying causes of

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

The goals of this study were to determine the effects of past-year stimulant and sedative drug use on alcohol-related aggression and to examine whether the relation between stimulant drug use and intoxicated aggression is better accounted for by behavioral disinhibition. Participants were 330 healthy social drinkers (164 men and 166 women) between 21 and 35 years of age. Past-year stimulant and sedative use and behavioral disinhibition were assessed via self-report questionnaires. Following the consumption of either an alcohol or a placebo beverage, participants were tested on a modified version of the Taylor Aggression Paradigm [Taylor, S. (1967). Aggressive behavior and physiological arousal as a function of provocation and the tendency to inhibit aggression. Journal of Personality, 35, 297-310] in which mild electric shocks were received from, and administered to, a fictitious opponent. Aggressive behavior was operationalized as the shock intensities administered to the fictitious opponent under conditions of low and high provocation. Results indicated that alcohol significantly strengthened the relation between stimulant drug use and aggression, but only among men. Behavioral disinhibition did not account for this effect. Regardless of past-year drug use, alcohol did not facilitate aggression among women. The present findings suggest that stimulant drug use may be a risk factor for intoxicated aggression for men. However, the underlying mechanisms accounting for this effect remain unclear.

Among various potential mechanisms that could explain alcohol carcinogenicity, the metabolism of ethanol to acetaldehyde represents an obvious possible mechanism, at least in some tissues. The fundamental principle of genotoxic carcinogenesis is the formation of mutagenic DNA adducts in proliferating cells. If not repaired, these adducts can result in mutations during DNA replication, which are passed on to cells during mitosis. Consistent with a genotoxic mechanism, acetaldehyde does react with DNA to form a variety of different types of DNA adducts. In this chapter we will focus more specifically on N2-ethylidene-deoxyguanosine (N2-ethylidene-dG), the major DNA adduct formed from the reaction of acetaldehyde with DNA and specifically highlight recent data on the measurement of this DNA adduct in the human body after alcohol exposure. Because results are of particular biological relevance for alcohol-related cancer of the upper aerodigestive tract (UADT), we will also discuss the histology and cytology of the UADT, with the goal of placing the adduct data in the relevant cellular context for mechanistic interpretation. Furthermore, we will discuss the sources and concentrations of acetaldehyde and ethanol in different cell types during alcohol consumption in humans. Finally, in the last part of the chapter, we will critically evaluate the concept of carcinogenic levels of acetaldehyde, which has been raised in the literature, and discuss how data from acetaldehyde genotoxicity are and can be utilized in physiologically based models to evaluate exposure risk.

Spring break (SB) can lead to heavy episodic drinking and increased alcohol-related risks. This may be especially relevant for women. The current study utilized deviance regulation theory to increase the use of protective behavioral strategies (PBSs) among female college students on SB. Female college students going on SB (n = 62) completed a screening, a pre-SB intervention (where they were randomly assigned to receive either a positively or negatively framed message about individuals who do or do not use PBS), and a post-SB assessment that provided alcohol and PBS use data for each day of SB (n = 620 person-days). Data were analyzed using a multilevel structural equation model. In the negative frame, SB PBS use was higher among those who perceived SB PBS norms to be more common on SB relative to non-SB. In the positive frame, SB PBS use was higher among those who perceived SB PBS norms to be less common on SB relative to non-SB. These associations did not result in lower alcohol consumption, but did result in a lower likelihood of experiencing alcohol-related problems during SB. These results suggest that a brief online intervention, that utilizes targeted messages based on normative perceptions of SB PBS use, could be an effective strategy for reducing alcohol-related consequences among college student women during SB.

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.

Alcohol misuse among adolescents is a common issue worldwide and is an emerging problem in China. This study aimed to investigate the prevalence of alcohol drinking and alcohol-related problems among Chinese adolescents and to explore their risk factors and connections.A cross-sectional study using an anonymous questionnaire was conducted among junior and senior high school students between 2010 and 2012. Data on self-reported alcohol use, alcohol-related problems, school factors, family factors, and psychosocial factors were collected. Descriptive analyses were made of the proportions of sociodemographics, family, school, and psychosocial factors. Multilevel logistic regression models were conducted to analyze the risk factors for alcohol drinking and alcohol-related problems.Of the 105,752 students who ranged in age from 9 to 21 years, the prevalence of current drinking among students was 7.3%, and 13.2% students reported having alcohol-related problems. Male students were 1.78 (95% confidence interval [CI] = 1.69-1.87) times more likely to be involved in current drinking and 1.86 (95% CI = 1.79-1.93) times more likely to have alcohol-related problems. Higher grade level students were at a higher risk of current drinking (adjusted odds ratio [AOR] = 1.09, 95% CI = 1.05-1.13) and having alcohol-related problems (AOR = 1.43, 95% CI = 1.42-1.58). Older students were more likely to report current drinking (AOR = 1.06, 95% CI = 1.04-1.17) and having alcohol-related problems (AOR = 1.83, 95% CI = 1.82-1.85). Having poor classmate relations (AOR = 1.28, 95% CI = 1.03-1.37), having poor relationships with teachers (AOR = 1.08, 95% CI = 1.00-1.16), and below average academic achievement (AOR = 1.50, 95% CI = 1.41-1.59) were positively associated with current drinking. Moreover, students with suicidal ideation were at a higher risk of current drinking (AOR = 1.70, 95% CI = 1.61-1.81) and having alcohol-related problems (AOR = 2.08, 95% CI = 1.98-2.16).

Age at onset of alcohol dependence (AO-AD) is a defining feature of multiple drinking typologies. AO-AD is heritable and likely shares genetic liability with other aspects of alcohol consumption. We examine whether polygenic variation in AO-AD, based on a genome-wide association study (GWAS), was associated with AO-AD and other aspects of alcohol consumption in two independent samples. Genetic risk scores (GRS) were created based on AO-AD GWAS results from a discovery sample of 1788 regular drinkers from extended pedigrees from the Collaborative Study of the Genetics of Alcoholism (COGA). GRS were used to predict AO-AD, AD and Alcohol dependence symptom count (AD-SX), age at onset of intoxication (AO-I), as well as maxdrinks in regular drinking participants from two independent samples—the Study of Addictions: Genes and Environment (SAGE; n=2336) and an Australian sample (OZ-ALC; n=5816). GRS for AO-AD from COGA explained a modest but significant proportion of the variance in all alcohol-related phenotypes in SAGE. Despite including effect sizes associated with large numbers of single nucleotide polymorphisms (SNPs; >110 000), GRS explained, at most, 0.7% of the variance in these alcohol measures in this independent sample. In OZ-ALC, significant but even more modest associations were noted with variance estimates ranging from 0.03 to 0.16%. In conclusion, there is modest evidence that genetic variation in AO-AD is associated with liability to other aspects of alcohol involvement. PMID:27003187

Background There is a lack of empirical analyses examining how alcohol consumption patterns in children relate to harms. Such intelligence is required to inform parents, children and policy relating to the provision and use of alcohol during childhood. Here, we examine drinking habits and associated harms in 15-16 year olds and explore how this can inform public health advice on child drinking. Methods An opportunistic survey of 15-16 year olds (n = 9,833) in North West England was undertaken to determine alcohol consumption patterns, drink types consumed, drinking locations, methods of access and harms encountered. Cost per unit of alcohol was estimated based on a second survey of 29 retail outlets. Associations between demographics, drinking behaviours, alcohol pricing and negative outcomes (public drinking, forgetting things after drinking, violence when drunk and alcohol-related regretted sex) were examined. Results Proportions of drinkers having experienced violence when drunk (28.8%), alcohol-related regretted sex (12.5%) and forgetting things (45.3%), or reporting drinking in public places (35.8%), increased with drinking frequency, binge frequency and units consumed per week. At similar levels of consumption, experiencing any negative alcohol-related outcome was lower in those whose parents provided alcohol. Drunken violence was disproportionately associated with being male and greater deprivation while regretted sex and forgetting things after drinking were associated with being female. Independent of drinking behaviours, consuming cheaper alcohol was related to experiencing violence when drunk, forgetting things after drinking and drinking in public places. Conclusion There is no safe level of alcohol consumption for 15-16 year olds. However, while abstinence removes risk of harms from personal alcohol consumption, its promotion may also push children into accessing drink outside family environments and contribute to higher risks of harm.

Alcoholism has been characterized as a systemic pro-inflammatory condition and alcohol withdrawal has been linked to various changes in the brain homeostasis, including oxidative stress and glutamate hyperactivity. N-acetylcysteine (NAC) is an anti-inflammatory and antioxidant multi-target drug with promising results in psychiatry, including drug addiction. We assessed the effects of NAC on the serum and brain inflammatory cytokines after cessation of chronic alcohol treatment in rats. Male Wistar rats received 2 g/kg alcohol or vehicle twice a day by oral gavage for 30 days. Rats were treated, from day 31 to 34, with NAC (60 or 90 mg/kg) or saline, intraperitoneally, once daily. Rats were sacrificed at day 35, trunk blood was collected and the frontal cortex and hippocampus dissected for assessment of TNF-α, IL-1β, IL-6, IL-18, IL-10. NAC prevented the increase of pro-inflammatory cytokines and the decrease of anti-inflammatory cytokine in the frontal cortex and hippocampus. No changes were observed on serum cytokines. We conclude that NAC protects against inflammation induced by chronic (30 days) alcohol ingestion followed by 5 days cessation in two rat brain areas. Because inflammation has been documented and associated with craving and relapse in alcoholics, the data revealed by this study points to the validity of NAC clinical evaluation in the context of alcohol detoxification and withdrawal.

Background Alcohol-induced intestinal dysbiosis disrupts homeostatic gut-liver axis function and is essential in the development of alcoholic liver disease. Here, we investigate changes in enteric microbiome composition in a model of early alcoholic steatohepatitis and dissect the pathogenic role of intestinal microbes in alcohol-induced liver pathology. Materials and methods Wild type mice received a 10-day diet that was either 5% alcohol-containing or an isocaloric control diet plus a single binge. 16S rDNA sequencing defined the bacterial communities in the cecum of alcohol- and pair-fed animals. Some mice were treated with an antibiotic cocktail prior to and throughout alcohol feeding. Liver neutrophils, cytokines and steatosis were evaluated. Results Acute-on-chronic alcohol administration induced shifts in various bacterial phyla in the cecum, including increased Actinobacteria and a reduction in Verrucomicrobia driven entirely by a reduction in the genus Akkermansia. Antibiotic treatment reduced the gut bacterial load and circulating bacterial wall component lipopolysaccharide (LPS). We found that bacterial load suppression prevented alcohol-related increases in the number of myeloperoxidase- (MPO) positive infiltrating neutrophils in the liver. Expression of liver mRNA tumor necrosis factor alpha (Tnfα), C-X-C motif chemokine ligand 1 (Cxcl1) and circulating protein monocyte chemoattractant protein-1 (MCP-1) were also reduced in antibiotic-treated alcohol-fed mice. Alcohol-induced hepatic steatosis measured by Oil-Red O staining was significantly reduced in antibiotic treated mice. Genes regulating lipid production and storage were also altered by alcohol and antibiotic treatment. Interestingly, antibiotic treatment did not protect from alcohol-induced increases in serum aminotransferases (ALT/AST). Conclusions Our data indicate that acute-on-chronic alcohol feeding alters the microflora at multiple taxonomic levels and identifies loss of Akkermansia as an

This study investigated the mediating effect of trait aggressivity on the relation between agreeableness and alcohol-related aggression in a laboratory setting. Participants were 116 healthy male social drinkers between 21 and 30 years of age. Agreeableness and trait aggressivity were measured using the Big Five Inventory and the Buss-Perry Aggression Questionnaire, respectively. Following the consumption of an alcohol or no-alcohol control beverage, participants completed a modified version of the Taylor Aggression Paradigm, in which electric shocks were received from and administered to a fictitious opponent during a competitive task. Aggression was operationalized as the proportion of the most extreme shocks delivered to the fictitious opponent under conditions of low and high provocation. Results indicated that lower levels of agreeableness were associated with higher levels of trait aggressivity. In turn, higher levels of trait aggressivity predicted extreme aggression in intoxicated, but not sober, participants under low, but not high, provocation. Findings highlight the importance of examining determinants of intoxicated aggression within a broader theoretical framework of personality.

Objective: The purpose of this study was to determine whether the relative risk of being involved in an alcohol-related crash has changed over the decade from 1996 to 2007, a period during which there has been little evidence of a reduction in the percentage of all fatal crashes involving alcohol. Method: We compared blood-alcohol information for the 2006 and 2007 crash cases (N = 6,863, 22.8% of them women) drawn from the U.S. Fatality Analysis Reporting System (FARS) with control blood-alcohol data from participants in the 2007 U.S. National Roadside Survey (N = 6,823). Risk estimates were computed and compared with those previously obtained from the 1996 FARS and roadside survey data. Results: Although the adult relative risk of being involved in a fatal alcohol-related crash apparently did not change from 1996 to 2007, the risk for involvement in an alcohol-related crash for underage women has increased to the point where it has become the same as that for underage men. Further, the risk that sober underage men will become involved in a fatal crash has doubled over the 1996–2007 period. Conclusions: Compared with estimates obtained from a decade earlier, young women in this study are at an increased risk of involvement in alcohol-related crashes.

The purpose of this study was to determine if a brief 10-item alcohol-related Facebook® activity (ARFA) questionnaire would predict alcohol use patterns in college students (N = 146). During a single laboratory session, participants first privately logged on to their Facebook® profiles while they completed the ARFA measure, which queries past 30 day postings related to alcohol use and intoxication. Participants were then asked to complete five additional questionnaires: three measures of alcohol use (the Alcohol Use Disorders Identification Test [AUDIT], the Timeline Follow-Back [TLFB], and the Personal Drinking Habits Questionnaire [PDHQ]), the Barratt Impulsiveness Scale (BIS-11), and the Marlowe-Crowne Social Desirability Scale (MC-SDS). Regression analyses revealed that total ARFA scores were significant predictors of recent drinking behaviors, as assessed by the AUDIT, TLFB, and PDHQ measures. Moreover, impulsivity (BIS-11) and social desirability (MC-SDS) did not predict recent drinking behaviors when ARFA total scores were included in the regressions. The findings suggest that social media activity measured via the ARFA scale may be useful as a research tool for identifying risky alcohol use.

The Lane Change Task was developed to provide an objective safety criterion for the assessment of driver distraction by in-vehicle information systems (IVIS). It consists of two basic driving tasks, namely lane keeping and lane changes. The LCT has been shown to reliably detect distraction from driving. As this test becomes increasingly important for the assessment of safety the validity of the LCT is crucial. In order to examine this further, the effect of an alcohol intoxication of 0.08 g/dl on the performance in the LCT was examined in the present study as the negative effects of alcohol on driving are well known. Twenty-three participants were tested under alcohol and placebo in a cross-over design measuring different performance indicators in the LCT. There were significant effects of alcohol during the lane keeping phase. However, these were much smaller than those typically found with distracting secondary tasks. The lane change phase was only marginally affected by alcohol. This result gives rise to some caution for interpreting effects in the LCT. The LCT is well able to detect distraction, as other studies have shown. However, our study with intoxicated participants shows that a small effect in the LCT does not necessarily mean that this condition does not impair driving.

The purpose of this study was to test the hypothesis that state anxiety operates as moderator of the alcohol-aggression relation. Participants were 80 healthy male social drinkers between 21 and 33 years of age. They were randomly assigned to 1 of 4 groups: (a) alcohol + anxiety induction (n = 20), (b) placebo + anxiety induction (n = 20), (c) alcohol + no anxiety induction (n = 20), and (d) placebo + no anxiety induction (n = 20). Anxiety was induced by informing participants that they had to deliver a speech about what they liked and disliked about their body in front of a video camera. A modified version of the Taylor Aggression Paradigm (S. Taylor, 1967) was then used to measure aggressive behavior in a situation where electric shocks were administered to, and received from, a fictitious opponent under the guise of a competitive reaction time task. Results indicated that the anxiety induction was successful in suppressing aggression for participants who received alcohol equal to levels seen in placebo controls. Findings are discussed within the context of a number of theories of alcohol's anxiolytic effects in relation to intoxicated aggression.

In this chapter, we review existing research regarding sex differences in alcohol's effects on neurobehavioral functions/processes. Drawn largely from laboratory studies, literature regarding acute alcohol administration and chronic alcohol misuse is explored focusing on commonly employed neuropsychologic domains (e.g., executive function, visuospatial skills, learning and memory, gait and balance), neurophysiologic measures (e.g., electroencephalography and event-related potentials), and structural and functional neuroimaging (e.g., magnetic resonance imaging (MRI), functional MRI, diffusion tensor imaging, positron emission tomography, and magnetic resonance spectroscopy). To provide a historical perspective on the development of these questions, we have included reference to early and more recent research. Additionally, specific biases, knowledge gaps, and continuing controversies are noted.

Two studies are reported using the theory of planned behavior (TPB) to predict and explain joining and not joining alcohol-related social gatherings among Korean undergraduates in various engineering majors. Specifically, considering that the attitudinal component of TPB is behavioral-outcome-based, the current study investigated whether the outcomes of engaging in a behavior and of not engaging in a behavior would similarly predict intentions to engage in a behavior and intentions to not engage in a behavior. The current study also examined whether intentions to engage and intentions to not engage would be significantly related to self-reported behavior a week later. Participants in Study 1 reported TPB components (attitudes toward behavior, subjective norms, perceived behavioral control, and behavioral intentions) concerning joining alcohol-related social gatherings. Participants in Study 2 reported TPB components concerning not joining alcohol-related social gatherings. Additionally, a week later, the participants in both studies reported their participation in alcohol-related social gatherings from the past week. Generally, the results showed that the TPB components were significantly associated with undergraduates' intentions to join and intentions to not join. Specifically, conversation-related attitudes and senior-junior relationship-related attitudes were significantly related to intentions to join, and only group-related attitudes were significantly related to intentions to not join. Intentions to join and intentions to not join were not significantly related to self-reported behavior of joining alcohol-related social gatherings a week later. The findings from the current research provide some evidence that joining or not joining alcohol-related social gatherings may not be mere behavioral opposites, predictable by the presence or absence of the same behavioral outcomes. These two aspects of the behavior may require assessment of different behavioral

In migrants alcohol-related problems increase with increasing age. This group, in particular, is hardly reached by alcohol-specific care offers. Thus our project aimed at the identification of target group-specific barriers to health-care use by means of a cross-sectional study (n=435). Based on these results a trans-cultural concept for alcohol prevention among elderly migrants was developed and evaluated in a cluster-randomised controlled trial (n=176).

High-throughout single nucleotide polymorphism detection technology and the existing knowledge provide strong support for mining the disease-related haplotypes and genes. In this study, first, we apply four kinds of haplotype identification methods (Confidence Intervals, Four Gamete Tests, Solid Spine of LD and fusing method of haplotype block) into high-throughout SNP genotype data to identify blocks, then use cluster analysis to verify the effectiveness of the four methods, and select the alcoholism-related SNP haplotypes through risk analysis. Second, we establish a mapping from haplotypes to alcoholism-related genes. Third, we inquire NCBI SNP and gene databases to locate the blocks and identify the candidate genes. In the end, we make gene function annotation by KEGG, Biocarta, and GO database. We find 159 haplotype blocks, which relate to the alcoholism most possibly on chromosome 1 approximately 22, including 227 haplotypes, of which 102 SNP haplotypes may increase the risk of alcoholism. We get 121 alcoholism-related genes and verify their reliability by the functional annotation of biology. In a word, we not only can handle the SNP data easily, but also can locate the disease-related genes precisely by combining our novel strategies of mining alcoholism-related haplotypes and genes with existing knowledge framework.

Japan passed the national law "Basic Act on Measures against Alcohol-related Health Harm" on December 2013. This law is expected to prevent inappropriate drinking that leads to alcohol-related problems such as physical and mental disorder, drunk driving, suicide, domestic violence, child abuse, and poor work performance. The physician's responsibilities under this law are described as follows: i) to provide high quality and appropriate medical care concerning alcohol-related health harm; ii) to reduce or eliminate the consumption of alcohol, thus preventing the progression of alcohol-related health harm; and iii) to coordinate these efforts amongst medical institutions. Based on this law, we believe that Japanese physicians will have essential roles in achieving the goals of this law and that we can fulfill our responsibilities by observing the following aspects: a) changing our message to the patients from "drink sensibly and moderately" to "low-risk drinking; but any drinking has a risk of harm and low-risk drinking is not risk-free"; b) encouraging the spread and use of Screening, Brief Intervention, and Referral to Treatment (SBIRT); and c) establishing community healthcare systems for alcohol-related problems, including dementia in the elderly and during alcohol emergencies.

A positive corelation between Alcoholics Anonymous (AA) involvement and better alcohol-related outcomes has been identified in research studies, but whether this correlation reflects a causal relationship remains a subject of meaningful debate. The present study evaluated the question of whether AA affiliation appears causally related to positive alcohol-related outcomes in a sample of 2,319 male alcohol-dependent patients. An initial structural equation model indicated that 1-year posttreatment levels of AA affiliation predicted lower alcohol-related problems at 2-year follow-up, whereas level of alcohol-related problems at 1-year did not predict AA affiliation at 2-year follow-up. Additional models found that these effects were not attributable to motivation or psychopathology. The findings are consistent with the hypothesis that AA participation has a positive effect on alcohol-related outcomes.

This study investigates pathways from alcohol outcome expectancies to alcohol-related problems (ARPs), considering alcohol volume and episodic heavy drinking (EHD) as potential mediators. It is further examined whether these pathways vary by age. The population-based sample comprised 6,823 individuals aged 18 to 64 years reporting alcohol use in the past year. Direct and indirect effects of five alcohol expectancies (social assertiveness, tension reduction, sexual enhancement, cognitive impairment, aggression) and alcohol use (average daily intake, EHD) on a latent measure of ARPs (six items of the Alcohol Use Disorders Identification Test) were investigated. A multiple-group structural equation model with three age groups (18 to 24, 25 to 44, 45 to 64 years) was examined. In individuals aged 18 to 24 years, social assertiveness expectancies were positively associated with average intake and EHD, which in turn were associated with more ARPs. In addition, expectancies related to cognitive impairment and aggression were directly linked to more ARPs without mediation in this age group. In individuals aged 25 years and older, tension reduction expectancies were associated with more ARPs through increased average intake. In contrast, high scores on cognitive impairment were associated with lower average intake and in turn with fewer ARPs. Challenging expectancies of sociability in young and expectancies of relaxation in mid adulthood might help decrease high-risk drinking and subsequently ARPs. Considering negative alcohol expectancies may help to identify younger individuals at high risk for ARPs, even if they have not previously exhibited repeated excessive drinking.

Objectives. The aim of this article is to represent the first reported case with cooccurrence of two rare alcohol related complications. Case Report. We report a 38-year-old man with chronic alcoholism who presented with both cranial and peripheral nerve palsy. On MRI examination characteristic findings of Marchiafava-Bignami disease were recognized. Discussion. Marchiafava-Bignami disease (MBD) is a rare complication of long-term, heavy alcohol abuse that has characteristic MRI findings. Acute alcohol related polyneuropathy (AARP) is another rare and not-well-understood complication of chronic alcohol abuse. We could not find any previous report of the cooccurrence of these two complications in the literature. PMID:27668107

There is agreement that physicians can play a major role in the prevention of alcohol problems among their patients and that medical schools should prepare physicians for this role by teaching three major subject areas: knowledge, attitudes and clinical skills. Despite this agreement and the acknowledged high prevalence of alcohol problems in clinical populations, medical school coverage of these problems is not proportional to their importance. Barriers to adequate coverage of alcohol problems are traditional attitudes, confusion as to whether such problems are "medical" and lack of adequate faculty role models. These problems could be remedied by encouragement and training of interested faculty members, establishment of substance abuse centres in university medical schools, integration of alcohol-related material with relevant topics in all departments and inclusion of alcohol-related questions on medical qualifying exams.

In adults, alcohol-related stimuli prime aggressive responding without ingestion or belief of ingestion. This represents either experiential or socially-and culturally-mediated learning. Using a laboratory-based competitive aggression paradigm, we replicated adult findings in 103 11-14 year old adolescents below the legal UK drinking age. Using a two-independent group design, priming with alcohol-related imagery led participants to deliver louder noise punishments in a competition task than priming with beverage-related images. This effect was stronger in participants scoring low on an internalization measure. Priming effects in relatively alcohol-naïve participants could constitute evidence of socio-cultural transmission of scripts linking alcohol use and aggression. The enhanced effect in lower internalization scorers suggests that alcohol priming might undermine behavioral inhibition processes in otherwise stable adolescents.

The present study investigated the role specific types of alcohol-related problems and life satisfaction play in predicting motivation to change alcohol use. Participants were 548 college students mandated to complete a brief intervention following an alcohol-related policy violation. Using hierarchical multiple regression, we tested for the presence of interaction and quadratic effects on baseline data collected prior to the intervention. A significant interaction indicated that the relationship between a respondent's personal consequences and his/her motivation to change differs depending upon the level of concurrent social consequences. Additionally quadratic effects for abuse/dependence symptoms and life satisfaction were found. The quadratic probes suggest that abuse/dependence symptoms and poor life satisfaction are both positively associated with motivation to change for a majority of the sample; however, the nature of these relationships changes for participants with more extreme scores. Results support the utility of using a multidimensional measure of alcohol related problems and assessing non-linear relationships when assessing predictors of motivation to change. The results also suggest that the best strategies for increasing motivation may vary depending on the types of alcohol-related problems and level of life satisfaction the student is experiencing and highlight potential directions for future research.
The present paper addressed the problem of the origin of alcohol-related social norms in the Saami minority in northern Norway. Based on data from studies of comparable ethnic minorities in Greenland, North America and Australia it could be expected that alcohol use- and abuse would be more prevalent in the Saami than in the Norwegian populations of northern Norway. No data to support this hypothesis exist. On the contrary, available data suggest that drinking problems in this group are similar to those of the majority in the area. The present paper developed the hypothesis that Saami alcohol-related social norms originated in the Laestadian religious revival. The paper investigated the impact of the Laestadian culture in the formation of alcohol-related social norms. It was concluded that the Laestadian sobriety norm, and the norm of abstinence from the use of adiafora, have influenced alcohol-related behaviour in the Saami group in such a way that this group does not conform to the drinking behaviour found in comparable minorities.

STUDY OBJECTIVE—To investigate the utility of capture-recapture methods to estimate prevalence of subjects with alcohol related disorders using multiple incomplete lists. DESIGN—This was a cross sectional study of alcohol related disorders in a large community. SETTING—During 1997 identified cases with known alcohol related disorders were independently flagged by four sources (self help volunteering groups; psychiatric ambulatory; public alcohology service; hospital discharges). PATIENTS—381 records were flagged, corresponding to 349 individual cases from a target population resident in a northern Italy area. MAIN RESULTS—The two sample capture-recapture estimates were clearly biased because of dependencies among sources. Estimates based on log-linear models showed prevalent counts ranged from 2297 (95% confidence intervals: 1524, 3794) to 2523 (95% confidence intervals: 1623, 4627) after adjustment for dependence among sources only or also for heterogeneity in catchability among age categories (< 50 and ⩾ 50 years), respectively. CONCLUSIONS—The study suggests that capture-recapture is an appropriate approach for estimating prevalence of subjects with alcohol related problems who seek or need treatment and assistance when different lists of alcoholics can be obtained from different types of agencies involved with problematic use of alcohol. Critical factors are the complexity in case definition and the analysis of heterogeneity among people. Accurate estimates are needed to plan and evaluate public health interventions.

In this article I describe the historical context for research on sexual minority women’s drinking, including the age-old tendency to link homosexuality and alcoholism; I summarize gaps and limitations that characterized much of the research on sexual minority women’s drinking over the past several decades; and I review recent literature to highlight progress in the field—with a particular focus on my own research related to risk and protective factors for heavy drinking and drinking-related problems among sexual minority women. I conclude with a discussion of barriers to treatment for sexual minority women and recommendations for substance abuse treatment providers. PMID:22470226

With a better understanding of the biologic basis of alcohol dependence and the considerable financial burden of alcohol abuse and dependence, the number of alcohol-related clinical pharmacotherapy trials has been on the rise. Subsequently, the potential to find efficacious treatments is more promising. Unfortunately, alcohol-related trials face a number of challenges, as a result of the difficulties that arise from traditional and outdated methods to collect data and ensure medication adherence. Novel technology-based assessments, such as ecological momentary assessment, interactive voice response, transdermal sensor and medication-event monitoring system provide a prospective solution—albeit not without possible concerns—to the difficulties faced in alcohol-related clinical trials. Clinical trials are meant to define the efficacy of the treatment and to determine an effective and safe dosage. However, due to lack of adherence a drug could inappropriately or mistakenly be judged as ineffective for treating a specific disorder. The described technologies may be important tools to prevent false negatives in validating drug efficacy, to provide consistency in clinical trials and to improve available data regarding the study of pharmacotherapies for alcohol dependence.

The New South Wales Tissue Resource Centre at the University of Sydney, Australia, is one of the few human brain banks dedicated to the study of the effects of chronic alcoholism. The bank was affiliated in 1994 as a member of the National Network of Brain Banks and also focuses on schizophrenia and healthy control tissue. Alcohol abuse is a major problem worldwide, manifesting in such conditions as fetal alcohol syndrome, adolescent binge drinking, alcohol dependency, and alcoholic neurodegeneration. The latter is also referred to as alcohol-related brain damage (ARBD). The study of postmortem brain tissue is ideally suited to determining the effects of long-term alcohol abuse, but it also makes an important contribution to understanding pathogenesis across the spectrum of alcohol misuse disorders and potentially other neurodegenerative diseases. Tissue from the bank has contributed to 330 peer-reviewed journal articles including 120 related to alcohol research. Using the results of these articles, this review chronicles advances in alcohol-related brain research since 2003, the so-called genomic age. In particular, it concentrates on transcriptomic approaches to the pathogenesis of ARBD and builds on earlier reviews of structural changes (Harper et al. Prog Neuropsychopharmacol Biol Psychiatry 2003;27:951) and proteomics (Matsumoto et al. Expert Rev Proteomics 2007;4:539).

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.

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.

The personality trait of impulsivity is predictive of heavy drinking and consequences among college students. The current study examined how impulsivity-measured via positive urgency, negative urgency, and sensation seeking-and a person's beliefs about the role alcohol plays in the college experience relate to drinking and consequences in a sample of 470 college students (mean age=19 years, 61.3% female, 59.8% White). In support of the hypotheses, sensation seeking independently predicted greater drinking, and both positive urgency and negative urgency predicted greater experience of alcohol-related negative consequences after controlling for consumption level. Moreover, alcohol beliefs moderated the relationship between impulsivity types and alcohol outcomes. Among students high (versus low) in sensation seeking, strong beliefs about alcohol's role in college life were related to significantly greater drinking, and among students high (versus low) in negative urgency, endorsing strong beliefs about alcohol's role in college life were related to greater levels of alcohol-related negative consequences. Overall, findings inform college prevention efforts by highlighting the need to distinguish unique facets of impulsivity and examine how they intersect with students' beliefs about alcohol in college.

This study identifies the individual, situational, and alcohol-related factors associated with reporting violent victimization to the police. Factors positively associated with reporting included older age and incident severity (the assailant's use of a weapon, incurring injury that required attendance at an emergency department). Factors negatively associated with reporting included higher educational qualifications, assault in the nighttime economy (NTE), and drinking more than two alcoholic drinks immediately prior to victimization. It is possible that drinkers engage in "moratorium" on reporting violence in the NTE. Recognizing and reducing the acceptability of violence in the NTE may help reduce incidence of alcohol-related violence. Organizations that use police records of violence to inform practice and policy should account for uneven distributions in reporting behavior when analyzing trends in violence.

The present study examined the impact of socially based descriptive norms on willingness to drink alcohol, drinker prototype favorability, affective alcohol attitudes, and perceived vulnerability for alcohol-related consequences within the Prototype Willingness model. Descriptive norms were manipulated by having 189 young adolescents view experimenter-created profile pages from the social networking site Facebook, which either showed older peers drinking or not. The results provided evidence that descriptive norms for alcohol use, as portrayed by Facebook profiles, significantly impact willingness to use, prototypes, attitudes toward use, and perceived vulnerability. A multiple mediation analysis indicated that prototypes, attitudes, and perceptions of use mediated the relationship between the content of the Facebook profile and willingness. These results indicate that adolescents who perceive that alcohol use is normative, as evidenced by Facebook profiles, are at higher risk for cognitions shown to predict alcohol use than adolescents who do not see alcohol use portrayed as frequently on Facebook.

Background Alcohol misuse is an important global health determinant and a major contributor to health inequalities. We aimed to investigate the association between school performance and alcohol-related disorders in early adulthood in a longitudinal register-based national cohort study. Methods We followed a register-based national cohort of Swedish citizens born 1973–1984 (N = 948 440) from compulsory school graduation at age 15–16 to 2009. We divided the population into five groups: high school marks (> mean + 1 SD); high average (between mean and mean + 1 SD); low average (between mean and mean − 1 SD); low (< mean – 1SD); and missing. Cox proportional hazard models were used to investigate the relation between school marks at time of graduation and hospital care for alcohol-related disorders in early adulthood. Results There was a steep gradient in the risk of alcohol-related disorders related to school performance. In comparison with peers in the top category of school marks, students with low marks had adjusted hazard ratios of 8.02 [95% confidence interval (CI) 7.20 to 8.91], low average 3.02 (2.72 to 3.35) and high average 1.55 (1.39 to 1.73). The risk associated with low school marks was stronger in the male population and in the group from high socioeconomic background. Conclusions The study demonstrated a strong graded relation between low school performance and alcohol-related disorders in young adulthood. School performance should be taken into account when developing prevention programmes/policies targeting alcohol misuse among teenagers and young adults, especially if the aim is to reach high-risk groups.

After high school, college students escalate their drinking at a faster rate than their noncollege-attending peers, and alcohol use in high school is one of the strongest predictors of alcohol use in college. Therefore, an improved understanding of the role of predictors of alcohol use during the critical developmental period when individuals transition to college has direct clinical implications to reduce alcohol-related harms. We used path analysis in the present study to examine the predictive effects of personality (e.g., impulsivity, sensation seeking, hopelessness, and anxiety sensitivity) and three measures of alcohol perception: descriptive norms, injunctive norms, and perceptions regarding the perceived role of drinking in college on alcohol-related outcomes. Participants were 490 incoming freshmen college students. Results indicated that descriptive norms, injunctive norms, and the role of drinking largely mediated the effects of personality on alcohol outcomes. In contrast, both impulsivity and hopelessness exhibited direct effects on alcohol-related problems. The perceived role of drinking was a particularly robust predictor of outcomes and mediator of the effects of personality traits, including sensation seeking and impulsivity on alcohol outcomes. The intertwined relationships observed in this study between personality factors, descriptive norms, injunctive norms, and the role of drinking highlight the importance of investigating these predictors simultaneously. Findings support the implementation of interventions that target these specific perceptions about the role of drinking in college.

Objective: This analysis tested whether comprehensive community interventions that focus on reducing alcohol availability and increasing substance abuse treatment can reduce alcohol related fatal traffic crashes. Intervention: Five of 14 communities awarded Fighting Back grants by The Robert Wood Johnson Foundation to reduce substance abuse and related problems attempted to reduce availability of alcohol and expand substance abuse treatment programs (FBAT communities). Program implementation began on 1 January 1992. Design: A quasi-experimental design matched each program community to two or three other communities of similar demographic composition in the same state. Main outcome measures: The ratio of fatal crashes involving a driver or pedestrian with a blood alcohol concentration of 0.01% or higher, 0.08% or higher, or 0.15% or higher were examined relative to fatal crashes where no alcohol was involved for 10 years preceding and 10 years following program initiation. Results: Relative to their comparison communities, the five FBAT communities experienced significant declines of 22% in alcohol related fatal crashes at 0.01% BAC or higher, 20% at 0.08% or higher, and 17% at 0.15% or higher relative to fatal crashes not involving alcohol. Conclusions: Community interventions to reduce alcohol availability and increase substance abuse treatment can reduce alcohol related fatal traffic crashes. PMID:15805436

Laboratory-based experimental research has demonstrated that the pharmacological effects of alcohol can increase aggressive responding. Given mixed findings and concerns regarding task validity, however, it remains uncertain whether this effect holds constant across men and women and whether variability in subjective alcohol intoxication contributes to alcohol-related aggression. In this investigation, the authors used 4 years of event-level data in a sample of 1,775 college students (140,618 total observations) to provide a test of laboratory-derived findings on the link between alcohol and aggression in an alternative methodology. They found support for several such findings: (a) Within-person increases in alcohol intoxication, as assessed by estimated blood alcohol concentrations (eBACs), were associated with increases in the probability of aggression at the drinking-episode level; (b) this association was significantly stronger among men than among women; and (c) within-person variability and between-persons individual differences in levels of subjective alcohol intoxication were associated with aggression over and beyond eBACs. Cross-methodological replication can reduce the impact of constraints specific to experimental studies on conclusions regarding alcohol's relation with aggression.

Objective To examine the impact of critical care on future alcohol-related behaviour. Further, it aimed to explore patterns of recovery for patients with and without alcohol use disorders beyond the hospital environment. Design In-depth, semistructured interviews with participants (patients) 3–7 months post intensive care discharge. Setting The setting for this study was a 20-bedded mixed intensive care unit (ICU), in a large teaching hospital in Scotland. On admission, patients were allocated to one of the three alcohol groups: low risk, harmful/hazardous and alcohol dependency. Participants 21 participants who received mechanical ventilation for greater than 3 days were interviewed between March 2013 and June 2014. Interventions None. Measurements and main results Four themes which impacted on recovery from ICU were identified in this patient group: psychological resilience, support for activities of daily living, social support and cohesion and the impact of alcohol use disorders on recovery. Participants also discussed the importance of personalised goal setting and appropriate and timely rehabilitation for alcohol-related behaviours during the critical care recovery period. Conclusions There is a significant interplay between alcohol misuse and recovery from critical illness. This study has demonstrated that at present, there is a haphazard approach to rehabilitation for patients after ICU. A more targeted rehabilitation pathway for patients leaving critical care, with specific emphasis on alcohol misuse if appropriate, requires to be generated. PMID:27048633

The factors underlying vulnerability to alcoholism are largely unknown. We identified in rodents an innate endophenotype predicting individual risk for alcohol-related behaviors that was associated with decreased expression of the neuroplasticity-related polysialylated neural cell adhesion molecule (PSA-NCAM). Depletion of PSA-NCAM in the ventromedial prefrontal cortex was sufficient to render mice unable to extinguish alcohol seeking, indicating a causal role of naturally occurring variation. These data suggest a mechanism of aberrant prefrontal neuroplasticity that underlies enhanced propensity for inflexible addiction-related behavior.

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.

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…

Alcohol-related partner aggression is a pervasive social problem throughout various life stages, including the transition to parenthood. Previous research shows that alcohol use is associated with partner aggression perpetration for both men and women; however, not all individuals who consume alcohol act aggressively. In this study, the moderating effects of general social support and partner-specific support on the association between prepregnancy alcohol use and recent partner physical aggression are investigated using a community sample of 98 pregnant couples. For men, high levels of general appraisal social support (i.e., someone to talk to about one's problems) increases the strength of the association between alcohol use and aggression perpetration, whereas partner-specific emotional support serves as a buffer. For women, general social support is not a significant moderator, but high levels of partner-specific instrumental support strengthens the association between alcohol use and aggression. These results can be applied to prevention and treatment programs for alcohol-related partner aggression.

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.

Research has shown that college students participating in athletics drink more than other students, yet relatively few studies have examined variables that are associated with alcohol-related outcomes among this population. The purpose of this study was to examine the relationships among trait urgency, general drinking motives and sport-related drinking motives, and both alcohol use and alcohol-related problems. Data were collected from 198 college students participating in either intercollegiate or recreational athletics at three U.S. universities. Structural equation modeling was used to examine a series of theoretically derived explanatory models. All variables included in the model were directly associated with alcohol use and/or alcohol-related problems. The specific patterns of relationships differed across the motives and trait urgency variables. Sport-related coping motives, sport-related positive reinforcement motives, and general enhancement motives had direct relationships with alcohol use, while trait urgency, general coping motives, and sport-related positive reinforcement motives had direct relationships with alcohol-related problems. Several indirect effects on alcohol use and alcohol-related problems were also found. This study suggests that general drinking motives, sport-related drinking motives, and trait urgency all serve as important predictors of alcohol-related outcomes in college athletes.

This study aimed to contrast student and not student outcome expectancies, and explore the diversity of alcohol-related cognitions within a wider student sample. Participants (n=549) were college students (higher education-typically aged 15-18 years), university students (further education-typically aged 18-22 years) and business people (white collar professionals <50 years) who completed questionnaires in their place of work or education. Overall positive expectancies were higher in the college students than in the business or university samples. However, not all expectancy subcategories followed this pattern. Participant groups of similar age were therefore alike in some aspects of their alcohol-related cognitions but different in others. Similarly, participant groups whom are divergent in age appeared to be alike in some of their alcohol-related cognitions, such as tension reduction expectancies. Research often homogenises students as a specific sub-set of the population, this paper hi-lights that this may be an over-simplification. Furthermore, the largely exclusive focus on student groups within research in this area may also be an oversight, given the diversity of the findings demonstrated between these groups.

Background: Alcohol-impaired driving is a major public health problem. National studies indicate that about 25% of college students have driven while intoxicated in the past month and an even greater percentage drive after drinking any alcohol and/or ride with an intoxicated driver. The purpose of this investigation was to examine the change in these various alcohol-related traffic risk behaviors as students progressed through their college experience. Methods: A cohort of 1,253 first-time first-year students attending a large, mid-Atlantic university were interviewed annually for four years. Repeated measures analyses were performed using generalized estimating equations (GEE) to evaluate age-related changes in prevalence and frequency of each behavior (i.e., ages 19 to 22). Results: At age 19, 17% wt of students drove while intoxicated, 42%wt drove after drinking any alcohol, and 38%wt rode with an intoxicated driver. For all three driving behaviors, prevalence and frequency increased significantly at age 21. Males were more likely to engage in these behaviors than females. To understand the possible relationship of these behaviors to changes in drinking patterns, a post-hoc analysis was conducted and revealed that while drinking frequency increased every year, frequency of drunkenness was stable for females, but increased for males. Conclusions: Alcohol-related traffic risk behaviors are quite common among college students, and take a significant upturn when students reach the age of 21. Prevention strategies targeted to the college population are needed to prevent serious consequences of these alcohol-related traffic risk behaviors. PMID:20528819

Previous research suggests that both jealousy and relationship contingent self-esteem (RCSE) are related to alcohol use and alcohol-related problems. No work, however, has examined these two constructs together as they relate to motives for alcohol use and alcohol-related problems. The current study aims to build upon emerging literature examining different types of jealousy (i.e., emotional, cognitive, and behavioral), relationship quality (i.e., satisfaction, commitment, closeness), RCSE, and alcohol use. More specifically, the current study aimed to examine the associations between RCSE and drinking to cope and RCSE and alcohol-related problems, in the context of the different types of jealousy. Moreover, the current study aimed to assess whether the associations between RCSE, jealousy, and drinking outcomes vary as a function of relationship quality. Two hundred and seventy seven individuals (87% female) at a large southern university participated in the study. They completed measures of RCSE, relationship satisfaction, commitment, closeness, and jealousy as well as alcohol-related outcomes. Using PROCESS, moderated mediational analyses were used to evaluate different types of jealousy as mediators of the association between RCSE and drinking to cope/alcohol-related problems. Further, we aimed to examine whether relationship quality moderated the association between RCSE and jealousy in predicting alcohol-related variables. Results indicated that cognitive jealousy mediated the association between both RCSE and drinking to cope and RCSE and alcohol-related problems. Further, relationship satisfaction, commitment, and closeness were all found to moderate the association between RSCE and cognitive jealousy such that at lower, but not higher levels of satisfaction, commitment, and closeness, cognitive jealousy mediated the association between RCSE and drinking to cope and RCSE and alcohol-related problems.

A substantial literature has identified risk factors for intoxicated aggression and the mechanisms by which these effects are exerted. This theoretical and empirical foundation is a valuable resource for the development of treatment inventions. In contrast, a comparable literature is not available to guide development of clinical interventions for intoxicated antigay aggression. To address this gap in the literature, the present article 1) identifies risk factors and mechanisms pertinent to alcohol-related antigay aggression, 2) advances predictions regarding how alcohol will increase antigay aggression, and 3) reviews societal- and individual-level considerations for intervention based upon these hypotheses.

This randomized experiment examines the effects of contextual information on undergraduate college student's levels of alcohol-related incident guardianship at college parties. The research is conceptualized using routine activities theory and the theory of planned behavior. The experiment examines attitudinal variations about heavy drinking differentiated by sex, athletic status, and location of the drinking event. The sex and athletic status variables produce statistically effects on the dependent variables, while location of the drinking event is not significant. The article concludes by discussing the importance of context as it pertains to the social norms marketing strategy utilized in much college alcohol programming, and suggests a more directed marketing approach.

Objectives Alcohol is responsible for a proportion of emergency admissions to hospital, with acute alcohol intoxication and chronic alcohol dependency (CAD) implicated. This study aims to quantify the proportion of hospital admissions through our emergency department (ED) which were thought by the admitting doctor to be (largely or partially) a result of alcohol consumption. Setting ED of a UK tertiary referral hospital. Participants All ED admissions occurring over 14 weeks from 1 September to 8 December 2012. Data obtained for 5497 of 5746 admissions (95.67%). Primary outcome measures Proportion of emergency admissions related to alcohol as defined by the admitting ED clinician. Secondary outcome measures Proportion of emergency admissions due to alcohol diagnosed with acute alcohol intoxication or CAD according to ICD-10 criteria. Results 1152 (21.0%, 95% CI 19.9% to 22.0%) of emergency admissions were thought to be due to alcohol. 74.6% of patients admitted due to alcohol had CAD, and significantly greater than the 26.4% with ‘Severe’ or ‘Very Severe’ acute alcohol intoxication (p<0.001). Admissions due to alcohol differed to admissions not due to alcohol being on average younger (45 vs 56 years, p<0.001) more often male (73.4% vs 45.1% males, p<0.001) and more likely to have a diagnosis synonymous with alcohol or related to recreational drug use, pancreatitis, deliberate self-harm, head injury, gastritis, suicidal ideation, upper gastrointestinal bleeds or seizures (p<0.001). An increase in admissions due to alcohol on Saturdays reflects a surge in admissions with acute alcohol intoxication above the weekly average (p=0.003). Conclusions Alcohol was thought to be implicated in 21% of emergency admissions in this cohort. CAD is responsible for a significantly greater proportion of admissions due to alcohol than acute intoxication. Interventions designed to reduce alcohol-related admissions must incorporate measures to tackle CAD. PMID:27324707

The negative impact of alcohol use on workplace performance is of significant concern to the U.S. military, given the costs associated with recruiting, hiring, and training personnel. However, little is known about the extent of potential alcohol use problems of recruits. We examined the history of alcohol-related problems among recruits entering the Air Force (N=37858). Although the average age of recruits was <21 years, 78% reported consuming alcohol and 49% reported binging before basic military training. Recruits who drank reported having negative alcohol-related outcomes (NAROs). In fact, >95% reported that they or someone else had been injured as a result of their drinking and that a relative, friend, doctor, or other health care worker has been concerned about their drinking. The remaining NAROs were reported by approximately one-quarter of those who drank. However, recruits who reported binge drinking were substantially more likely to report more NAROs, such as morning drinking, inability to stop drinking, having others be concerned about their drinking, having blackouts, fighting, having injured or been injured, feeling guilty about their drinking, and wanting to reduce the amount they drink. Results suggest that alcohol-related problems are common among recruits before basic military training and screening for future problems may be beneficial.

The present study examined three alcohol-perception variables (descriptive norms, injunctive norms, and college-related alcohol beliefs) as mediators of the predictive effects of four personality traits (impulsivity, sensation seeking, anxiety sensitivity, and hopelessness) on alcohol use and alcohol-related consequences in a sample of mandated college students (n=875). Our findings replicated several findings of a previous study of incoming freshman college students (Hustad et al., in press) in that impulsivity and hopelessness had direct effects on alcohol-related problems, sensation seeking and impulsivity had indirect effects on alcohol-related outcomes via college-related alcohol beliefs, and college-related alcohol beliefs predicted both alcohol use and alcohol-related problems. We discuss the implications of our findings for global college student interventions as well as personality-targeted interventions.

This paper examines alcohol-related social problems among Mexican Americans living along the U.S.-Mexico border and in non-border areas. Interviews were conducted among Mexican Americans in the border regions of California, Arizona, New Mexico, and Texas (N=1307). Non-border respondents were interviewed primarily in Houston and Los Angeles (N=1288) as part of the Hispanic Americans Baseline Alcohol Survey (HABLAS). Both the border and HABLAS surveys employed multistage cluster sample designs (response rates were 67% and 76%, respectively). In the bivariate analysis, there were no significant differences between border and non-border areas in the proportion of those with one or more social problem. In non-border areas, the prevalence of alcohol problems did not differ significantly by age. However, along the border the prevalence of alcohol problems was significantly different across age groups, with 18 to 29year old men and women having the highest prevalence. The final models showed no residence effect on problem likelihood. Drinking was strongly associated with problems. Although young border residents had higher problem prevalence rates than older residents, the logistic regression models showed no effect of border residence on the likelihood of problems, indicating that problems are due to alcohol consumption, not the border environment. The border, however, did appear to influence more drinking among young people. Regardless of residence, alcohol treatment and preventive interventions tailored to Mexican Americans are essential and special attention should be focused on younger individuals near the border.

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.

This study examined the relations among alcohol-related problems, perceived burdensomeness, thwarted belongingness, and suicide proneness in undergraduate college students (N = 996). As hypothesized, alcohol-related problems, perceived burdensomeness, and thwarted belongingness were all significantly and positively correlated with suicide proneness. The relation between experiencing alcohol-related problems and suicide proneness was, in part, accounted for by perceived burdensomeness and thwarted belongingness. Additionally, the mediation via perceived burdensomeness was significantly stronger than the mediation via thwarted belongingness. Results suggest that it would be advisable for clinicians to be aware of students’ experiences with alcohol-related problems in conjunction with their levels of burdensomeness and belongingness when assessing for suicide risk PMID:21883409

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.

Time perspective is an individual difference variable which assesses the extent to which orientation to the past, present and future affects current behaviors. The present study investigated the viability of temporal profiles and the degree (if any) to which these predict meaningful differences in alcohol-related problems. Participants were undergraduates recruited from a University in the North West of England. Full survey data were available for 455 individuals (aged 18-25; 49.7% male) on (a) time perspective, and (b) alcohol-related problems. Four profiles emerged and were labeled Future-Positive, Present, Past Negative-Future, and Ambivalent. As hypothesized, the Future-Positive profile was associated with the best alcohol-related outcomes. The Present profile was associated with the worst outcomes. This study demonstrates that temporal profiles are associated with alcohol-related problems.

This study aimed to determine the prevalence of responsible hospitality policies in a group of licensed premises associated with alcohol-related harm. During March 1999, 108 licensed premises with one or more police-identified alcohol-related incidents in the previous 3 months received a visit from a police officer. A 30-item audit checklist was used to determine the responsible hospitality policies being undertaken by each premises within eight policy domains: display required signage (three items); responsible host practices to prevent intoxication and under-age drinking (five items); written policies and guidelines for responsible service (three items); discouraging inappropriate promotions (three items); safe transport (two items); responsible management issues (seven items); physical environment (three items) and entry conditions (four items). No premises were undertaking all 30 items. Eighty per cent of the premises were undertaking 20 of the 30 items. All premises were undertaking at least 17 of the items. The proportion of premises undertaking individual items ranged from 16% to 100%. Premises were less likely to report having and providing written responsible hospitality documentation to staff, using door charges and having entry/re-entry rules. Significant differences between rural and urban premises were evident for four policies. Clubs were significantly more likely than hotels to have a written responsible service of alcohol policy and to clearly display codes of dress and conditions of entry. This study provides an indication of the extent and nature of responsible hospitality policies in a sample of licensed premises that are associated with a broad range of alcohol related harms. The finding that a large majority of such premises appear to adopt responsible hospitality policies suggests a need to assess the validity and reliability of tools used in the routine assessment of such policies, and of the potential for harm from licensed premises.

Objective The purpose of this study is to investigate whether pregaming (i.e., drinking prior to a social event) is a risk factor for hospitalization. Participants Participants (N=516) were undergraduate students with an alcohol-related sanction. Method Participants completed a survey about alcohol use, as well as behaviors and experiences prior to and during the referral event. The dependent variable was whether participants received medical attention at an emergency department during the sanction event. Results Results indicated that older students, females who pregame, students with higher alcohol use screening scores, lighter drinkers, and higher numbers of drinks before the referral event all increased the odds of receiving medical attention. Pregaming alone was not significantly related to receiving medical attention in the multivariate analysis. Conclusions Female students who pregame appear to be at risk for requiring hospitalization after drinking when controlling for the number of drinks consumed. PMID:24635415

The mechanisms of alcohol-related peripheral neuropathy (ALPN) are poorly understood. We hypothesize that, like alcohol-related liver and brain degeneration, ALPN may be mediated by combined effects of insulin/IGF resistance and oxidative stress. Adult male Long Evans rats were chronically pair-fed with diets containing 0% or 37% ethanol (caloric), and subjected to nerve conduction studies. Chronic ethanol feeding slowed nerve conduction in the tibial (p = 0.0021) motor nerve, and not plantar sensory nerve, but it did not affect amplitude. Histological studies of the sciatic nerve revealed reduced nerve fiber diameters with increased regenerative sprouts, and denervation myopathy in ethanol-fed rats. qRT-PCR analysis demonstrated reduced mRNA levels of insulin, IGF-1, and IGF-2 polypeptides, IGF-1 receptor, and IRS2, and ELISAs revealed reduced immunoreactivity for insulin and IGF-1 receptors, IRS-1, IRS-4, myelin-associated glycoprotein, and tau in sciatic nerves of ethanol-fed rats (all p < 0.05 or better). The findings suggest that ALPN is characterized by (1) slowed conduction velocity with demyelination, and a small component of axonal degeneration; (2) impaired trophic factor signaling due to insulin and IGF resistance; and (3) degeneration of myelin and axonal cytoskeletal proteins. Therefore, ALPN is likely mediated by molecular and signal transduction abnormalities similar to those identified in alcoholic liver and brain degeneration. PMID:23016131

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.

Background Little is known about differences in alcohol use and alcohol-related problems between transgender- and nontransgender-identified populations. Using data from a large-scale health survey, we compare the drinking patterns and prevalence of alcohol-related problems of transgender-identified individuals to nontransgender-identified males and females. For transgender-identified people, we examine how various forms of victimization relate to heavy episodic drinking (HED). Methods Cross-sectional surveys were completed by 75,192 students aged 18–29 years attending 120 post-secondary educational institutions in the United States from 2011–2013. Self-reported measures included alcohol use, alcohol-related problems, victimization, and sociodemographics, including 3 gender-identity groups: transgender-identified individuals; nontransgender-identified males; and nontransgender-identified females. Results Compared to transgender-identified individuals, nontransgender-identified males were more likely to report HED in the past 2 weeks (relative risk=1.42; p=0.006); however, nontransgender-identified males and females reported HED on fewer days than transgender-identified people (incidence-rate ratios [IRRs] ranged from 0.28–0.43; p-values<0.001). Compared to transgender-identified people, nontransgender-identified males and females had lower odds of past-year alcohol-related sexual assault and suicidal ideation (odds ratios ranged from 0.24–0.45; p-values<0.05). Among transgender-identified people, individuals who were sexually assaulted (IRR=3.21, p=0.011) or verbally threatened (IRR=2.42, p=0.021) in the past year had greater HED days than those who did not experience those forms of victimization. Conclusions Compared to transgender-identified people, nontransgender-identified males and females: have fewer HED occasions (despite nontransgender-identified males having greater prevalence of HED); and are at lower risk for alcohol-related sexual assaults and

OBJECTIVE: To examine the association between acculturation, birthplace, and alcohol-related social problems across Hispanic national groups. METHOD: 5,224 Hispanic adults (18+ years) were interviewed using a multistage cluster sample design in Miami, New York, Philadelphia, Houston, and Los Angeles. RESULTS: Multivariate analysis shows no association between acculturation and problems among men or women. Birthplace is a risk factor for social problems among both genders. Among men, Mexican Americans, Puerto Ricans, and South/Central Americans are more likely to report social problems than Cuban Americans. Other risk factors for men are unemployment, a higher volume of drinking, and a higher frequency of binge drinking. Among women, Mexican American origin and binge drinking are also risk factors for reporting problems. CONCLUSIONS: U.S.-born Hispanics may experience stress and other detrimental effects to health because of their minority status, which may increase the likelihood of more drinking and the development of alcohol-related problems.

Use and abuse of alcohol are common findings when unnatural deaths are investigated as evidenced by high blood- and urine- alcohol concentrations (BAC and UAC) at autopsy. Because ethanol is metabolized in the liver until the time of death, the autopsy BAC or UAC might be negative even though the deceased had consumed alcohol in the immediate ante-mortem period. Analysis of the non-oxidative metabolite of ethanol [ethyl glucuronide (EtG)] offers a more sensitive test of recent drinking. In this paper, we determined the concentrations of ethanol and EtG in urine samples from 972 consecutive forensic autopsies. In 425 cases (44%) both EtG and ethanol were positive, which supports ante-mortem drinking. In 342 cases (35%), both EtG and ethanol was negative, which speaks against any consumption of alcohol just before death. In 181 cases, ethanol was negative in urine (<0.2 g/kg), whereas EtG was positive (>0.5 mg/L), which points towards ingestion of alcohol some time before death. In these cases, mean and median concentrations of EtG were 53.2 mg/L and 23.7 mg/L, respectively, although there was no mention of alcohol on 131 of the death certificates. Alcohol was mentioned on death certificates as an underlying or immediate cause of death or a contributing factor in 435 (45%) cases, which rose to 566 (58%) cases when positive EtG results were included. This article demonstrates the usefulness of EtG analysis in routine post-mortem toxicology when ante-mortem drinking and alcohol-related deaths are investigated.

Alcoholism is a complex, multifactorial disorder involving problematic ethanol ingestion; it results from the interplay between genetic and environmental factors. Personality, likewise, is formed from a combination of inherited and acquired influences. Because selected dimensions of emotional temperament are associated with distinct neurochemical substrates contributing to specific personality phenotypes, certain aspects of abnormal emotional traits in alcoholics may be inherited. Emotions involve complex subjective experiences engaging multiple brain regions, most notably the cortex, limbic system, and cerebellum. Results of in vivo magnetic resonance imaging and post-mortem neuropathological studies of alcoholics indicate that the greatest cortical loss occurs in the frontal lobes, with concurrent thinning of the corpus callosum. Additional damage has been documented for the amygdala and hippocampus, as well as in the white matter of the cerebellum. All of the critical areas of alcoholism-related brain damage are important for normal emotional functioning. When changes occur in these brain regions, either as a consequence of chronic ethanol abuse or from a genetic anomaly affecting temperament and/or a vulnerability to alcoholism, corresponding changes in emotional functions are to be expected. In alcoholics, such changes have been observed in their perception and evaluation of emotional facial expressions, interpretation of emotional intonations in vocal utterances, and appreciation of the meaning of emotional materials.

Background Sexual offences are a global public health concern. Recent changes in the law in England and Wales have dramatically altered the legal landscape of sexual offences, but sexual assaults where the victim is voluntarily intoxicated by alcohol continue to have low conviction rates. Worldwide, students are high consumers of alcohol. This research aimed to compare male and female students in relation to their knowledge and attitudes about alcohol and sexual activity and to identify factors associated with being the victim of alcohol-related non-consensual sex. Methods 1,110 students completed an online questionnaire. Drinking levels were measured using the Alcohol Use Disorder Identification Test. Non-consensual sexual experiences were measured using the Sexual Experience Survey. Univariate and multivariate analyses were undertaken using chi square and backwards stepwise logistic regression respectively. Results A third of respondents had experienced alcohol-related non-consensual sex. Male and female students differed in the importance they gave to cues in deciding if a person wished to have sex with them and their understanding of the law of consent. 82.2% of women who had experienced alcohol-related non-consensual sex were hazardous drinkers compared to 62.9% who drank at lower levels (P < 0.001). Differences existed between men and women, and between those who had and had not experienced alcohol-related non-consensual sex, in relation to assessments of culpability in scenarios depicting alcohol-related intercourse. A third of respondents believed that a significant proportion of rapes were false allegations; significantly more men than women responded in this way. Conclusions Alcohol-related coerced sexual activity is a significant occurrence among students; attitudinal and knowledge differences between males and females may explain this. Educational messages that focus upon what is deemed acceptable sexual behaviour, the law and rape myths are needed but

Objective: Despite showing reductions in college student drinking, interventions have shown some inconsistency in their ability to successfully decrease consequences. With the goal of improving prevention efforts, the purpose of this study was to examine the role of consequence-specific constructs, in addition to drinking, that influence students’ experiences with alcohol-related problems. The study examined how drinking and protective behaviors mediated the relationships between students’ willingness to experience consequences, intentions to avoid them, and four categories of alcohol-related problems (physiological, social, sexual, and academic). Method: First-year college student drinkers (n = 2,024) at a large northeastern university completed surveys during the fall and spring of their freshman year. Results: As expected, different patterns of associations emerged for physiological and nonphysiological consequences. When physiological consequences (e.g., hangover, vomiting) were examined, drinking significantly mediated the effect of willingness on the consequences. Drinking-specific protective behaviors indirectly influenced consequences through drinking behaviors whereas general protective behaviors did not. When nonphysiological (e.g., social, sexual, academic) consequences were examined, drinking and general protective behaviors emerged as significant mediators of the effects of willingness and intentions on the consequences, whereas drinking-specific protective behaviors did not. Conclusions: The results suggest that prevention efforts (e.g., personalized feedback) could be tailored to address specific types of protective behaviors as well as specific types of consequences frequently experienced by college students.

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.

There is substantial evidence for a significant genetic component to the risk for alcoholism. In searching for genes that contribute to this risk, the diagnostic criteria for alcohol dependence may not be the optimal phenotype; rather, creation of a more homogeneous phenotype will lead to a more homogeneous genetic etiology. Items from the Semi-Structured Assessment for the Genetics of Alcoholism collected from 830 individuals in 105 alcoholic families were used in a latent class analysis to identify a more homogeneous alcoholism-related phenotype. A four-class solution was chosen: class 1, unaffected group; class 2, mildly problematic group; class 3, moderately affected group; and class 4, severely affected group. Classes 3 and 4 had higher symptom endorsement probabilities than classes 1 and 2 for items reflecting severe alcohol dependence, and were combined to provide enough sibling pairs for genetic linkage analysis. A total of 291 markers distributed throughout the genome, with an average intermarker distance of 14 cM, were genotyped. Linkage analysis was performed to detect loci underlying classes 3 and 4, the moderately and severely affected alcoholics, of whom 88% met the Collaborative Study of the Genetics of Alcoholism, and >99% met ICD-10 criteria for alcohol dependence. Evidence for a locus on chromosome 16, near the marker D16S675, was found with a maximum multipoint lod score of 4.0. Analysis of additional markers on chromosome 16 yielded a lod score of 3.2, narrowed the critical region, and placed the gene between D16S475 and D16S675 in a 15 cM interval.

The goal of the present study was to examine scenarios for using two schematic organizers--schematic knowledge maps and conceptual matrices--in integrating episodic and semantic knowledge about alcohol. Seventy students from undergraduate general psychology classes participated for course credit. Participants were assigned to either a schematic organizer group or an essay writing group. These groups were subdivided further into two treatment sequences: episodic/semantic and semantic/episodic. The episodic activity required participants to complete materials using their own alcohol-related experiences, whereas the semantic activity required participants to annotate expert materials. Assessment measures used were consumer-satisfaction questionnaires and free-recall tests. While no preferences were established for any one scenario, the episodic activities were rated higher than the semantic activities regardless of integration sequence. The semantic/episodic integration scenario did produce higher recall scores for the expert information.

Aim: This paper describes Chinese university students' understanding of the meaning of the alcohol-related flushing response and how they reacted to their own and someone else's flushing in a group drinking situation. Method: The researcher surveyed 530 Chinese university students about their understanding of flushing and their perception of how people respond to a person who visibly flushes while drinking alcohol. Findings: Most students did not know about the physiological cause of flushing. There were significant gender differences in both reactions to and perception of responses to a person who flushes. There was no direct relationship between flushing and drinking behaviour. Conclusions: This description of flushing behaviour and responses to a flushing person is discussed in terms of educational opportunities to change behaviours that could reduce the cancer related risks of this visibly at-risk group.

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.

Background Availability of alcohol is a major policy issue for governments, and one of the availability factors is the density of alcohol outlets within geographic areas. Objective The aim of this study is to investigate the association between alcohol outlet density and hospital admissions for alcohol-related conditions in a national (English) small area level ecological study. Methods This project will employ ecological correlation and cross-sectional time series study designs to examine spatial and temporal relationships between alcohol outlet density and hospital admissions. Census units to be used in the analysis will include all Lower and Middle Super-Output Areas (LSOAs and MSOAs) in England (53 million total population; 32,482 LSOAs and 6781 MSOAs). LSOAs (approximately 1500 people per LSOA) will support investigation at a fine spatial resolution. Spatio-temporal associations will be investigated using MSOAs (approximately 7500 people per MSOA). The project will use comprehensive coverage data on alcohol outlets in England (from 2003, 2007, 2010, and 2013) from a commercial source, which has estimated that the database includes 98% of all alcohol outlets in England. Alcohol outlets may be classified into two broad groups: on-trade outlets, comprising outlets from which alcohol can be purchased and consumed on the premises (eg, pubs); and off-trade outlets, in which alcohol can be purchased but not consumed on the premises (eg, off-licenses). In the 2010 dataset, there are 132,989 on-trade and 51,975 off-trade outlets. The longitudinal data series will allow us to examine associations between changes in outlet density and changes in hospital admission rates. The project will use anonymized data on alcohol-related hospital admissions in England from 2003 to 2013 and investigate associations with acute (eg, admissions for injuries) and chronic (eg, admissions for alcoholic liver disease) harms. The investigation will include the examination of conditions that
High risk drinking is linked with high rates of physical harm. The reported incidence of alcohol - related trauma among Aboriginal and Torres Strait Islander people in the Northern Territory is the highest in the world. Facial fractures are common among young Aboriginal and Torres Strait Islanders. They are often linked with misuse of alcohol in the Northern Territory and are frequently secondary to assault. This review focuses on alcohol-related trauma in the Territory and draws attention to an urgent need for preventative health approach to address this critical issue. PMID:22862897

Social scripts are commonly shared representations of behavior in social contexts, which are seen to be partly transmitted through social and cultural media. Research suggests that people hold scripts associated with alcohol-related aggression, but, unlike general aggression scripts, there is little evidence of social transmission. To demonstrate social transmission of alcohol-related aggression scripts, learning mechanisms based on personal experience should be minimized. We used a lexical decision task to examine implicit links between alcohol and aggression in alcohol-naïve adolescents who have limited personal or vicarious experience of alcohol-related aggression. One hundred and four 11-14 year old adolescents made lexical decisions on aggressive or nonaggressive words preceded by 40-ms alcohol or nonalcohol word primes. Repeated measures analyses of group data showed that alcohol word primes did not lead to faster responses to aggressive words than to nonaggressive words, nor were responses to aggressive words faster when they were preceded by alcohol word primes than by nonalcohol word primes. However, at an individual level, faster recognition times to the alcohol prime/aggression target word combination predicted aggression on a competitive laboratory task in 14 year olds only. This occurred only when the competitive aggression task was preceded by a visual presentation of alcoholic, but not nonalcoholic beverage, images. We concluded that alcohol-related aggression scripts are not strongly developed in this age group, but individual differences in script strength are linked to alcohol-related laboratory aggression.

, traditional norms that may directly pertain to hyperfemininzed Asian-American women, including modesty and sexual fidelity, may protect against heavy episodic drinking (Young et al. 2005). Conversely, the risk for heavy episodic drinking may be enhanced in men who strive to demonstrate traditional notions of masculinity through risk-taking and endorsement of playboy norms (Iwamoto et al. 2010). Although this review has illustrated the contemporary state of research on alcohol use among Asian Americans, it also highlights the significant limitations in this literature. Many of the studies reviewed here have used cross-sectional data, which do not allow researchers to infer causality between the various sociocultural factors and problematic alcohol use. One way of addressing this gap in the existing literature may be to implement longitudinal designs to further understand how the temporal relationship between sociocultural factors, including acculturation and gender norms, may impact alcohol use and alcohol-related problem trajectories. There also is a pressing need to develop greater understanding of within-group differences among U.S.-born and foreign-born Asian Americans as well as among as specific ethnic groups. To date, epidemiological research has largely neglected to examine these significant discrepancies. Given the growing prevalence of alcohol use and alcohol-related problems among Asian-American women (Grant et al. 2004; Iwamoto et al. 2010), studies also should focus on this group and explore how the intersection of gender and culture may influence alcohol use. Finally, the majority of research on this population has been conducted in college samples; therefore, it is important to also examine community samples, including U.S.-born young adults who are not attending college and older adult Asian-American populations.

Research increasingly finds that race/ethnicity needs to be taken into account in the modelling of associations between protective factors and adolescent drinking behaviors in order to understand family effects and promote positive youth development. The current study examined racial/ethnic variation in the prospective effects of family cohesion on adolescent alcohol-related problems using a nationally representative sample. Data were drawn from the first two waves of the National Longitudinal Study of Adolescent to Adult Health and included 10,992 (50% female) non-Hispanic Asian, non-Hispanic Black, Latino, and non-Hispanic White 7th-12th graders. Consistent with Hirschi's social control theory of youth delinquency, higher levels of family cohesion predicted lower levels of future adolescent alcohol-related problems, independent of race/ethnicity, sex, age, baseline alcohol-related problems, and family socioeconomic status. Findings from moderation analyses indicated that the magnitude of associations differed across groups such that the protective effect of family cohesion was strongest among White adolescents. For Latino adolescents, family cohesion was not associated with alcohol-related problems. Future longitudinal cross-racial/ethnic research is needed on common and unique mechanisms underlying differential associations between family processes and adolescent high-risk drinking. Understanding these processes could help improve preventive interventions, identify vulnerable subgroups, and inform health policy aimed at reducing alcohol-related health disparities.

Objective: A family history of alcoholism is a significant risk factor for the development of alcohol use disorders (AUDs). Because common structural abnormalities are present in reward and affective brain regions in alcoholics and those with familial alcoholism, the current study examined the relationship between familial loading of AUDs and volumes of the amygdala and nucleus accumbens (NAcc) in largely alcohol-naive adolescents, ages 12–16 years (N = 140). Method: The amygdala and NAcc were delineated on each participant’s T1-weighted anatomical scan, using FMRIB Software Library’s FMRIB Integrated Registration & Segmentation Tool, and visually inspected for accuracy and volume outliers. In the 140 participants with accurate segmentation (75 male/65 female), subcortical volumes were represented as a ratio to intracranial volume (ICV). A family history density (FHD) score was calculated for each adolescent based on the presence of AUDs in first- and second-degree relatives (range: 0.03–1.50; higher scores represent a greater prevalence of familial AUDs). Multiple regressions, with age and sex controlled for, examined the association between FHD and left and right amygdala and NAcc volume/ICV. Results: There was a significant positive relationship between FHD and left NAcc volume/ICV (ΔR2 = .04, p = .02). Post hoc regressions indicated that this effect was only significant in females (ΔR2 = .11, p = .006). Conclusions: This finding suggests that the degree of familial alcoholism, genetic or otherwise, is associated with alterations in reward-related brain structure. Further work will be necessary to examine whether FHD is related to future alcohol-related problems and reward-related behaviors. PMID:25486393

Ninety-two British, caucasian, alcoholic patients with liver disese were grouped on the basis of hepatic histology into fatty change, hepatitis with or without cirrhosis, and cirrhosis alone. Men with alcoholic hepatitis with or without cirrhosis showed an increased incidence of the histocompatibility antigen HLA-B8 (P less than 0.02). Increased measles antibody titres were found in patients without cirrhosis with or without hepatitis and were associated with the B8 phenotype in both sexes. Rubella antibody titres and percentage DNA-binding were raised in patients with cirrhosis and showed no association with the B8 phenotype. Concentrations of IgM and IgA were were raised in patients with stetosis and with hepatitis, while in patients with cirrhosis IgG concentrations were also increased. Low titres of autoantibodies were found in all histological groups. It is possible that the development of hepatitis in response to alcohol abuse may be influenced, at least in men, by a gene linked to the B locus. Otherwise, immune processes associated with alcohol-related liver disease are probably secondary phenomena. PMID:7400347

Alcohol-related traumatic brain injury (TBI) is a common condition in medical and forensic practice, and results in high prehospital mortality. We investigated the mechanism of chronic alcoholism-related mortality by examining the effects of alcohol on the synapses of the medulla oblongata in a rat model of TBI. Seventy adult male Sprague-Dawley rats were randomly assigned to either ethanol (EtOH) group, EtOH-TBI group, or control groups (water group, water-TBI group). To establish chronic alcoholism model, rats in the EtOH group were given EtOH twice daily (4 g/kg for 2 weeks and 6 g/kg for another 2 weeks). The rats also received a minor strike on the occipital tuberosity with an iron pendulum. Histopathologic and ultrastructure changes and the numerical density of the synapses in the medulla oblongata were examined. Expression of postsynaptic density-95 (PSD-95) in the medulla oblongata was measured by ELISA. Compared with rats in the control group, rats in the chronic alcoholism group showed: (1) minor axonal degeneration; (2) a significant decrease in the numerical density of synapses (p < 0.01); and (3) compensatory increase in PSD-95 expression (p < 0.01). Rats in the EtOH-TBI group showed: (1) high mortality (50%, p < 0.01); (2) inhibited respiration before death; (3) severe axonal injury; and (4) decrease in PSD-95 expression (p < 0.05). Chronic alcoholism induces significant synapse loss and axonal impairment in the medulla oblongata and renders the brain more susceptible to TBI. The combined effects of chronic alcoholism and TBI induce significant synapse and axon impairment and result in high mortality.

Background—Uncertainty exists about the extent and consequences of a return to alcohol consumption after liver transplantation for alcoholic liver disease (ALD). Aims—To determine the prevalence and consequences of alcohol consumption in patients transplanted for ALD. Methods—A retrospective case controlled study of all patients transplanted for ALD at the Queen Elizabeth Hospital, Birmingham, between 1987 and 1996. Results—Seventy patients with ALD were transplanted, of which 59 survived more than three months; 56 were interviewed. Twenty eight had consumed some alcohol after transplantation; for the nine "heavy drinkers" (HD), the median time to resumption of alcohol intake was six months and for the 19 "moderate drinkers" (MD) it was eight months. There was no significant difference in episodes of acute rejection or compliance with medication between those who were abstinent, MD, or HD. Histological evidence of liver injury was common in ALD patients who had returned to drink. Mild fatty change was found in 1/11 biopsy specimens from abstinent patients but moderate to severe fatty change and ballooned hepatocytes were seen in 3/5 MD and 2/5 HD specimens. Two HD patients had early fibrosis. One HD patient has died of alcohol related complications. Conclusions—Moderate to heavy alcohol consumption occurs in patients transplanted for ALD. Patient recall of abstinence advice is unreliable, and patients return to alcohol mainly within the first year after liver transplantation. Return to alcohol consumption after liver transplantation is associated with rapid development of histological liver injury including fibrosis.

Little is known about the subjective experience of alcohol desire and craving in young people. Descriptions of alcohol urges continue to be extensively used in the everyday lexicon of young, non-dependent drinkers. Elaborated Intrusion (EI) Theory contends that imagery is central to craving and desires, and predicts that alcohol-related imagery will be associated with greater frequency and amount of drinking. This study involved 1535 age stratified 18-25 year olds who completed an alcohol-related survey that included the Imagery scale of the Alcohol Craving Experience (ACE) questionnaire. Imagery items predicted 12-16% of the variance in concurrent alcohol consumption. Higher total Imagery subscale scores were linearly associated with greater drinking frequency and lower self-efficacy for moderate drinking. Interference with alcohol imagery may have promise as a preventive or early intervention target in young people.

In order to evaluate the frequency of depressive symptomatology (DS) and alcohol-related problems (ARP) during the academic training of medical students from Universidad Nacional Mayor de San Marcos, a cross-sectional study was conducted among students from first to sixth year of career. The Zung Self-Rating depression scale was used to evaluate DS and the CAGE questionnaire to evaluate ARP. 23.3% of participants had DS, and 7.3% had ARP. We found that the frequency of DS and ARP was higher among students in the first years of career. We recommend it is necessary to take action in the prevention and detection of these disorders from the first years of training of medical students.

Alcohol use generally peaks during the early twenties and declines with age. These declines, referred to as “maturing out,” are presumed to result from the acquisition of adult roles (e.g. marriage, employment) incompatible with alcohol use. Recent empirical evidence suggests that variables other than role transitions (e.g. personality) may also be important in understanding this process. Changes in identity that occur during emerging adulthood may also be linked to the process of maturing out of heavy drinking, though no studies have yet addressed this possibility. Utilizing data from a large sample of graduating college students (N = 907) during senior year (wave 1) and the two following years (waves 2-3), the current study examined relations between aspects of emerging adult identity and drinking outcomes (alcohol use and problems). Using time varying covariate growth models, results indicated that several facets of emerging adult identity conferred risk for the failure to mature out of heavy drinking and alcohol-related problems. Experimentation/possibilities emerged as a significant risk factor for both heavy drinking and alcohol problems, but these effects diminished considerably when accounting for personality risk. In contrast, although small in magnitude, effects of self-focus on heavy drinking and negativity/instability on alcohol-related problems were relatively independent of effects of other established predictors. The effect for negativity/instability was evident only at the final wave. The findings have important implications for theories of “maturing out” and may ultimately inform tailoring or refinement of prevention/intervention approaches for emerging adults. PMID:27077443

Recent empirical evidence suggests that variables other than role transitions (e.g., personality) may also be important in understanding this process. Changes in identity that occur during emerging adulthood may also be linked to the process of maturing out of heavy drinking, though no studies have yet addressed this possibility. Utilizing data from a large sample of graduating college students (N = 907) during senior year (Wave 1) and the 2 following years (Waves 2-3), the current study examined relations between aspects of emerging adult identity and drinking outcomes (alcohol use and problems). Using time-varying covariate growth models, results indicated that several facets of emerging adult identity conferred risk for the failure to mature out of heavy drinking and alcohol-related problems. Experimentation/possibilities emerged as a significant risk factor for both heavy drinking and alcohol problems, but these effects diminished considerably when accounting for personality risk. In contrast, although small in magnitude, effects of self-focus on heavy drinking and negativity/instability on alcohol-related problems were relatively independent of effects of other established predictors. The effect for negativity/instability was evident only at the final wave. The findings have important implications for theories of maturing out and may ultimately inform tailoring or refinement of prevention/intervention approaches for emerging adults.

Background The incidence of mandibular fractures in the Northern Territory of Australia is very high, especially among Indigenous people. Alcohol intoxication is implicated in the majority of facial injuries, and substance use is therefore an important target for secondary prevention. The current study tests the efficacy of a brief therapy, Motivational Care Planning, in improving wellbeing and substance misuse in youth and adults hospitalised with alcohol-related facial trauma. Methods and design The study is a randomised controlled trial with 6 months of follow-up, to examine the effectiveness of a brief and culturally adapted intervention in improving outcomes for trauma patients with at-risk drinking admitted to the Royal Darwin Hospital maxillofacial surgery unit. Potential participants are identified using AUDIT-C questionnaire. Eligible participants are randomised to either Motivational Care Planning (MCP) or Treatment as Usual (TAU). The outcome measures will include quantity and frequency of alcohol and other substance use by Timeline Followback. The recruitment target is 154 participants, which with 20% dropout, is hoped to provide 124 people receiving treatment and follow-up. Discussion This project introduces screening and brief interventions for high-risk drinkers admitted to the hospital with facial trauma. It introduces a practical approach to integrating brief interventions in the hospital setting, and has potential to demonstrate significant benefits for at-risk drinkers with facial trauma. Trial Registration The trial has been registered in Australian New Zealand Clinical Trials Registry (ANZCTR) and Trial Registration: ACTRN12611000135910. PMID:23106916

Background Although drinking for tension reduction has long been posited as a risk factor for alcohol-related problems, studies investigating anxiety in relation to risk for alcohol problems have returned inconsistent results, leading researchers to search for potential moderators. Negative urgency (the tendency to become behaviorally dysregulated when experiencing negative affect) is a potential moderator of theoretical interest because it may increase risk for alcohol problems among those high in negative affect. The present study tested a cross-sectional mediated moderation hypothesis whereby an interactive effect of anxiety and negative urgency on alcohol problems is mediated through coping-related drinking motives. Method The study utilized baseline data from a hazardously drinking sample of young adults (N = 193) evaluated for participation in a randomized controlled trial of naltrexone and motivational interviewing for drinking reduction. Results The direct effect of anxiety on physiological dependence symptoms was moderated by negative urgency such that the positive association between anxiety and physiological dependence symptoms became stronger as negative urgency increased. Indirect effects of anxiety and negative urgency on alcohol problems (operating through coping motives) were also observed. Conclusions Although results of the current cross-sectional study require replication using longitudinal data, the findings suggest that the simultaneous presence of anxiety and negative urgency may be an important indicator of risk for AUDs via both direct interactive effects and indirect additive effects operating through coping motives. These findings have potentially important implications for prevention/intervention efforts for individuals who become disinhibited in the context of negative emotional states. PMID:26031346

Background Previous studies have already substantiated alcohol’s causal role in injuries. Yet the role that alcoholic beverage preferences and the drinking context play in the risk for injury is still under-investigated. In this study a cross-national comparison of the association between alcohol and injury focusing on beverage type preference and the drinking context is reported. Methods Emergency department injured patients were interviewed in eight countries from the Latin American and Caribbean (LAC) region. Data on the type of alcoholic beverage, total alcohol volume, and the place where the injury occurred were obtained from patients who reported any alcohol consumption within 6 hours prior to being injured. Patients who did not drink prior to injury were also asked about their typical drinking pattern and the injury place. Differences within- and between-groups were evaluated regarding patients’ typical drinking and drinking before injury. Results Beer was the most prevalent beverage type usually consumed among injured patients across countries, however, patients who drank before injury had a higher typical consumption of spirits than those not drinking prior to injury. The total alcohol volume typically consumed and drinking in public settings were also found to be positively associated with alcohol-related injury. Conclusions A similar beverage-specific association with alcohol-related injury was found across LAC countries, mainly attributed to beer consumption, and spirits drinkers seem to have a greater chance of becoming involved in injury events. Future prevention strategies should inform the public about harms from drinking associated with the context in which drinking takes place. PMID:24556276

In Australia, the immediate post-school period (known as 'Schoolies') is associated with heavy drinking and high levels of alcohol-related harm. This study investigated students' intended alcohol consumption during Schoolies to inform interventions to reduce alcohol-related harm among this group. An online survey was administered to students in their senior year of schooling. Included items related to intended daily alcohol consumption during Schoolies, amount of money intended to be spent on alcohol over the Schoolies period, and past drinking behaviour. On average, participants (n=187) anticipated that they would consume eight standard drinks per day, which is substantially higher than the recommended maximum of no more than four drinks on a single occasion. Participants intended to spend an average of A$131 on alcohol over the Schoolies period. Although higher than national guidelines, intended alcohol consumption was considerably lower than has been previously documented during Schoolies events. The substantial amounts of money expected to be spent during Schoolies suggest this group has adequate spending power to constitute an attractive target market for those offering alternative activities that are associated with lower levels of alcohol-related harm.

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.

Approximately half of all alcohol-related crime is violent crime associated with heavy episodic drinking. Multi-component interventions are highly acceptable to communities and may be effective in reducing alcohol-related crime generally, but their impact on alcohol-related violent crime has not been examined. This study evaluated the impact and benefit-cost of a multi-component intervention (increasing community and liquor licensees' awareness, police activity, and feedback) on crimes typically associated with alcohol-related violence. The intervention was tailored to weekends identified as historically problematic in 10 experimental communities in NSW, Australia, relative to 10 control ones. There was no effect on alcohol-related assaults and a small, but statistically significant and cost-beneficial, effect on alcohol-related sexual assaults: a 64% reduction in in the experimental relative to control communities, equivalent to five fewer alcohol-related sexual assaults, with a net social benefit estimated as AUD$3,938,218. The positive benefit-cost ratio was primarily a function of the value that communities placed on reducing alcohol-related harm: the intervention would need to be more than twice as effective for its economic benefits to be comparable to its costs. It is most likely that greater reductions in crimes associated with alcohol-related violence would be achieved by a combination of complementary legislative and community-based interventions.

Introduction Alcohol use and alcohol-related problems are on the rise in low- and middle-income countries. Expenditure on alcohol is an important problem for families and communities and needs to be assessed. Aim This study examines level of alcohol consumption and expenditure on alcohol in a district in Vietnam. Methods A cross-sectional survey was conducted in a rural district in northern Vietnam. Multi-stage sampling was employed to randomly select participants from 20 communities and a town in the same district. One thousand five hundred and sixty-four adults (765 males and 799 females) aged 18–60 years were interviewed. Information about alcohol use as well as expenditure on alcohol consumption four weeks prior to the interview was gathered. Non-parametric tests and log-linear regression were employed to compare expenditure on alcohol consumption across socioeconomic groups. Results The prevalence of alcohol use one month prior to interview was 35% (66% among men and 5% among women). The median alcohol consumption among those who reported use of alcohol in the week prior to the interview was 7.9 standard drinks. Excessive drinking (more than 14 standard drinks per week for men and more than seven standard drinks per week for women) occurred among 35% of those who used alcohol. Median expenditure for alcohol consumption during one month by those who drank alcohol was USD 3.5, accounting for 4.6% of household food expenditure, 2.7% of total household expenditure, and 1.8% of household income. The differences in alcohol consumption and expenditure between sexes and between socioeconomic groups are also presented. Conclusion Our study confirms that alcohol consumption and alcohol-related problems are common among men in Vietnam. The share of alcohol expenditure in total household expenditure is substantial, especially among poor households. This should be considered an important public health issue, which needs to be taken into account in the alcohol policy

Alcohol-related myopathy (Alc-M) is highly prevalent among heavy drinkers, although its pathogenesis is not well understood. We hypothesize that Alc-M is mediated by combined effects of insulin/IGF resistance and oxidative stress, similar to the effects of ethanol on liver and brain. We tested this hypothesis using an established model in which adult rats were pair-fed for 8 weeks with isocaloric diets containing 0% (N = 8) or 35.5% (N = 13) ethanol by caloric content. Gastrocnemius muscles were examined by histology, morphometrics, qRT-PCR analysis, and ELISAs. Chronic ethanol feeding reduced myofiber size and mRNA expression of IGF-1 polypeptide, insulin, IGF-1, and IGF-2 receptors, IRS-1, and IRS-2. Multiplex ELISAs demonstrated ethanol-associated inhibition of insulin, IRS-1, Akt, and p70S6K signaling, and increased activation of GSK-3β. In addition, ethanol-exposed muscles had increased 4-hydroxy-2-nonenal immunoreactivity, reflecting lipid peroxidation, and reduced levels of mitochondrial Complex IV, Complex V, and acetylcholinesterase. These results demonstrate that experimental Alc-M is associated with inhibition of insulin/IGF/IRS and downstream signaling that mediates metabolism and cell survival, similar to findings in alcoholic liver and brain degeneration. Moreover, the increased oxidative stress, which could be mediated by mitochondrial dysfunction, may have led to inhibition of acetylcholinesterase, which itself is sufficient to cause myofiber atrophy and degeneration.

Chemosensory (olfaction-taste) dysfunctions are considered as reliable biomarkers in many neurological and psychiatric states. However, experimental measures of chemosensory abilities are lacking in alcohol-dependence (AD) and Korsakoff Syndrome (KS, a neurological complication of AD), despite the role played by alcohol-related odors and taste in the emergence and maintenance of AD. This study thus investigated chemosensory impairments in AD and KS. Olfactory-gustatory measures were taken among 20 KS, 20 AD, and 20 control participants. Olfaction (odor detection-discrimination-identification) was assessed using the "Sniffin Sticks" battery and taste was measured using the "Taste Strips" task. Impairments were found for high-level olfaction in AD (odor discrimination) and KS (odor discrimination-identification), even after controlling for psychopathological comorbidities. Gustatory deficits were also observed in both groups, indexing a global deficit for chemosensory perception. Finally, the gradient of impairment between the successive disease stages for odor identification suggests that the hypothesis of a continuum between AD and KS regarding cognitive deficits can be generalized to chemosensory perception. AD and KS are thus characterized by deficits in chemosensory abilities, which could constitute a marker of the AD-KS transition. In view of its deleterious influence on everyday life, chemosensory dysfunction should also be taken into account in clinical settings.

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.

Although alcohol use has long been a significant cause of hospital presentations, little is published regarding the long-term demographic changes that have occurred at a single hospital site. To address this deficit, we prospectively studied all acute alcohol-related presentations to Bellevue Hospital Center (New York, NY) and compared this contemporary data set with one from the same institution from 1902 to 1935. We prospectively identified all patients presenting to the emergency department because of acute alcohol use over an 8-week period in 2009. We described the basic attributes of patients presenting currently because of alcohol and compared these data to those previously described between 1902 and 1935. We also compared our census data with contemporaneous data from all patients presenting to this hospital site. During the study period, 560 patients presented because of acute alcohol use which extrapolated to an estimated 3,800 patients over the calendar year. This compares to 7,600 presentations recorded annually early in the twentieth century. Twelve percent of patients in 2009 were female as compared to 18 % of patients between 1934 and 1935. Patients with alcohol-related presentations in 2009 were more likely to be admitted than contemporaneous patients without an alcohol-related presentation (30 vs. 19 % admitted; p < 0.001). Since first measured 110 years ago at one large New York City hospital, alcohol-related presentations remain common representing 5 % of all emergency department visits. This demonstrates alcoholism's continuing toll on society's limited medical resources and on public health as a whole.
Background This study examines whether alcohol-related hospitalization predicts survey non-response, and evaluates whether this missing data result in biased estimates of the prevalence of hazardous alcohol use and abstinence. Methods Registry data on alcohol-related hospitalizations during the preceding ten years were linked to two representative surveys. Population data corresponding to the surveys were derived from the Stockholm County registry. The alcohol-related hospitalization rates for survey responders were compared with the population data, and corresponding rates for non-responders were based on the differences between the two estimates. The proportions with hazardous alcohol use and abstinence were calculated separately for previously hospitalized and non-hospitalized responders, and non-responders were assumed to be similar to responders in this respect. Results Persons with previous alcohol-related admissions were more likely currently to abstain from alcohol (RR=1.58, p<.001) or to have hazardous alcohol use (RR=2.06, p<.001). Alternatively, they were more than twice as likely to have become non-responders. Adjusting for this skewed non-response, i.e., the underrepresentation of hazardous users and abstainers among the hospitalized, made little difference to the estimated rates of hazardous use and abstinence in total. During the ten-year period 1.7% of the population were hospitalized. Conclusions Few people receive alcohol-related hospital care and it remains unclear whether this group’s underrepresentation in surveys is generalizable to other groups, such as hazardous users. While people with severe alcohol problems – i.e. a history of alcohol-related hospitalizations – are less likely to respond to population surveys, this particular bias is not likely to alter prevalence estimates of hazardous use.

Background The power to influence many social determinants of health lies within local government sectors that are outside public health's traditional remit. We analyse the challenges of achieving health gains through local government alcohol control policies, where legal and professional practice frameworks appear to conflict with public health action. Methods Current legislation governing local alcohol control in England and Wales is reviewed and analysed for barriers and opportunities to implement effective population-level health interventions. Case studies of local government alcohol control practices are described. Results Addressing alcohol-related health harms is constrained by the absence of a specific legal health licensing objective and differences between public health and legal assessments of the relevance of health evidence to a specific place. Local governments can, however, implement health-relevant policies by developing local evidence for alcohol-related health harms; addressing cumulative impact in licensing policy statements and through other non-legislative approaches such as health and non-health sector partnerships. Innovative local initiatives—for example, minimum unit pricing licensing conditions—can serve as test cases for wider national implementation. Conclusions By combining the powers available to the many local government sectors involved in alcohol control, alcohol-related health and social harms can be tackled through existing local mechanisms.

Although levels of heavy drinking and alcohol-related problems are high in college students, there is significant variability in the number and type of problems experienced, even among students who drink heavily. African American students drink less and experience fewer alcohol-related problems than European American students, but are still at risk, and little research has investigated the potentially unique patterns and predictors of problems among these students. Depression, distress tolerance, and delay discounting have been implicated in adult substance abuse and may be important predictors of alcohol problem severity among college students. We examined the relationship between these variables and alcohol-related problems among African American and European American students (N = 206; 53% female; 68% European American; 28% African American) who reported recent heavy drinking. In regression models that controlled for drinking level, depression, distress tolerance, and delay discounting were associated with alcohol problems among African American students, but only depression was associated with alcohol problems among European American students. These results suggest that negative affect is a key risk factor for alcohol problems among college student drinkers. For African American students, the inability to tolerate negative emotions and to organize their behavior around future outcomes may also be especially relevant risk factors.

Purpose Attention-deficit/hyperactivity disorder (ADHD) has been shown to be related to a higher risk of developing psychiatric problems such as depressive disorders, substance use disorder, and impulsivity. Adults who have comorbid ADHD and alcohol use disorder (AUD) are at greater risk of negative outcomes. Thus, it is important to evaluate the relationship of ADHD symptoms and the severity of alcohol-related problems among patients with AUD. The aim of the present study was to evaluate the effect of ADHD symptoms on severity of alcohol-related problems, while controlling the effects of depression and impulsivity in a sample of inpatients with AUD. Patients and methods Participants (n=190) were evaluated with the Beck Depression Inventory, the Short Form Barratt Impulsiveness Scale, the Michigan Alcohol Screening Test, and the Adult ADHD Self-Report Scale. Results Severity of the scale scores was positively correlated with each other. Although severity of depression and impulsivity (particularly non-planning impulsivity) predicted the severity of alcohol-related problems in a linear regression model, when severity of ADHD symptoms was included in the analysis, the inattentive subscale score, in particular, predicted the severity of alcohol-related problems together with non-planning impulsivity, whereas depression was no longer a predictor. Conclusion These findings suggest that, together with non-planning impulsivity, symptoms of ADHD (particularly inattentive factor) are an important factor that predict alcohol-related problems, while controlling the severity of depressive symptoms among inpatients with AUD.

The objective of this review is to provide an update on existing research examining alcohol-related consequences among college students with relevance for individual-based interventions. While alcohol-related consequences have been a focus of study for several decades, the literature has evolved into an increasingly nuanced understanding of individual and environmental circumstances that contribute to risk for experiencing consequences. A number of risk factors for experiencing alcohol-related consequences have been identified, including belonging to specific student subgroups (e.g., Greek organizations) or drinking during high-risk periods, such as spring break. In addition, the relationship between students’ evaluations of both negative and positive consequences and their future drinking behavior has become a focus of research. The current review provides an overview of high-risk student subpopulations, high-risk windows and activities, and college students’ subjective evaluations of alcohol related consequences. Future directions for research are discussed and include determining how students’ orientations toward consequences change over time, identifying predictors of membership in high-risk consequence subgroups, and refining existing measures of consequences to address evolving research questions.

Background The average U.S. adolescent is exposed to about 2.5 hours of popular music per day and 8 mentions of alcohol brands every day. Alcohol brand mentions may function as advertising whether or not they are sanctioned by the alcohol industry. Our study aimed to determine associations between adolescents' involvement with music containing alcohol brand mentions and alcohol-related behaviors. Methods In 2010–2011 we conducted a random-digit-dial survey using national U.S. land line and cell phone frames. Through screening interviews, we identified 6,466 eligible households with subjects between 15 to 23 years of age, of whom 3422 (52%) completed the telephone survey. Of these, 2541 opted to participate in a subsequent Web-based component. Independent variables included a composite score indicating owning and liking popular songs with alcohol brand mentions and correct recall of alcohol brands in songs. Outcome measures included ever having consumed a complete drink, ever bingeing, bingeing at least monthly, and having experienced problems from alcohol use. Results Among the 2541 participants, compared with those in the lowest tertile on the receptivity scale, those in the highest tertile had higher odds of having had a complete drink (OR=3.4; 95% CI=2.2, 5.2) after adjusting for age, sex, race/ethnicity, socioeconomic status, sensation seeking, friend alcohol use, and parent alcohol use. Compared with those who did not identify at least one alcohol brand correctly, those who did had over twice the odds of having had a complete drink (OR=2.1; 95% CI=1.2, 3.8) after adjusting for all covariates. Results were also significant for the outcome of ever bingeing but not for bingeing at least monthly or having had problems due to drinking. Conclusions In a national sample of U.S. adolescents and young adults, there were independent associations between involvement with popular music containing alcohol brand mentions and both having ever had a complete drink and

Additional work is needed to determine how and/or why the relationship between alcohol use and increased risk for partner aggression exists. Researchers have begun to examine whether alcohol-related outcome expectancies (i.e., beliefs about the cognitive and behavioral effects of alcohol) are associated with partner aggression irrespective of alcohol use. We examined the relationship between alcohol use, alcohol expectancies, and partner aggression among 360 males arrested for a domestic violence offense and court-mandated to treatment. Results indicate that certain alcohol expectancies do play a role in the relationship between alcohol use and some forms of partner aggression. PMID:25519237

Bullying perpetration and victimization as externalizing and internalizing pathways: A retrospective study linking parenting styles and self-esteem to depression, alcohol use, and alcohol-related problems

Emerging research suggests significant positive associations between bullying and substance use behaviors. However, these studies typically focused either on the link between substance use and bullying perpetration or victimization, and few have conceptualized bullying perpetration and/or victimization as mediators. In this study, we simultaneously tested past bullying perpetration and victimization as mediational pathways from retrospective report of parenting styles and global self-esteem to current depressive symptoms, alcohol use and alcohol-related problems. Data were collected from a college sample of 419 drinkers. Mediation effects were conducted using a bias-corrected bootstrap technique in structural equation modeling. Two-path mediation analyses indicated that mother and father authoritativeness were protective against bully victimization and depression through higher self-esteem. Conversely, having a permissive or authoritarian mother was positively linked to bullying perpetration, which in turn was associated with increased alcohol use, and to a lesser degree, more alcohol-related problems. Mother authoritarianism was associated with alcohol-related problems through depressive symptoms. Three-path mediation analyses suggested a trend in which individuals with higher self-esteem were less likely to report alcohol-related problems through lower levels of bullying victimization and depression. Results suggested that bullying perpetration and victimization may respectively serve as externalizing and internalizing pathways through which parenting styles and self-esteem are linked to depression and alcohol-related outcomes. The present study identified multiple modifiable precursors of, and mediational pathways to, alcohol-related problems which could guide the development and implementation of prevention programs targeting problematic alcohol use.

ABSTRACT Many epidemiological studies have demonstrated a correlation between alcohol intake and the occurrence of cancer in humans. All types of alcoholic beverages are associated with an increased risk which suggests that ethanol itself is the crucial compound which causes that effect. The International Agency for Research for Cancer classified alcohol consumption and acetaldehyde associated with alcohol consumption as carcinogenic for humans (group 1): oral cavity, pharynx, larynx, esophagus, colorectal, liver and female breast. The mechanisms by which alcohol consumption exerts its carcinogenic effect have not been defined fully, although plausible events include: a genotoxic effect of acetaldehyde; increased estrogen concentration, which is important for breast carcinogenesis; a role as solvent of tobacco carcinogens; production of reactive oxygen species and nitrogen species; and change in folate metabolism. Most alcohol-induced diseases increases in a linear fashion as intake increases: oral, esophagus and colon cancer fall into this pattern: very little is known about safe margins of alcohol consumption. Given the linear dose-response relation between alcohol intake and risk of cancer, control of heavy drinking remains the main target for cancer control. In healthy subjects, European Code Against Cancer recommends keeping daily consumption within two drinks for man and one drink for women. In our opinion, there are not enough data to support the actually safe intake of alcohol. Any level of alcohol consumption increase the risk of developing an alcohol related cancer. The level of risk increases in line with the level consumption. PMID:22879847

The primary purpose of this article is to apply the attention allocation model (AAM; Steele & Josephs, 1990) to the explanation, as well as the prevention, of alcohol-related violence. The AAM contends that alcohol has a “myopic” effect on attentional capacity that presumably facilitates aggression by narrowing attentional focus on the most salient provocative cues, that are naturally present in hostile situations, rather than less salient inhibitory cues. Data are presented to demonstrate support for the AAM with regard to alcohol-related aggression. The model has also been expanded to suggest some intermediary mechanisms that may account for how distracting attention away from provocative cues might be involved in the reduction of aggression. Finally, a number of practical suggestions are put forth regarding how the AAM can be applied to the prevention of intoxicated aggression. PMID:19938917

The current study examined gender-specific associations between trauma cognitions, alcohol cravings and alcohol-related consequences in individuals with dually diagnosed PTSD and alcohol dependence (AD). Participants (N = 167) had entered a treatment study for concurrent PTSD and AD; baseline information was collected from participants about PTSD-related cognitions in three areas: negative cognitions about self, negative cognitions about the world, and self-blame; and two aspects of AD, alcohol cravings and consequences of AD. Gender differences were examined while controlling for PTSD severity. The results indicate that negative cognitions about the self are significantly related to alcohol cravings in men but not women, and that interpersonal consequences of AD are significantly related to self-blame in women but not in men. These findings suggest that for individuals with comorbid PTSD and AD, psychotherapeutic interventions that focus on reducing trauma-related cognitions are likely to reduce alcohol cravings in men and relational problems in women.

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

Suicide is one of the major causes of deaths worldwide. Several studies have showed that alcohol use disorders (AUD) are associated with suicide ideation, suicide attempts, and suicide completion. The majority of the theoretical conceptualization and the bulk of evidence on suicidal behavior and AUD are based on investigations of nonfatal cases because data on nonfatal suicidal behaviors are more readily available. This study aims to explore demographic, clinical, and behavioral dimensions in a large sample of alcohol-related suicides compared to an age-gender matched sample of non-AUD suicides to identify specific factors associated with AUD suicides. We conducted a psychological autopsy study with 158 pairs of AUD and non-AUD suicides. Findings showed that AUD suicides have lower educational level, more biological children and were more likely to be heavy smokers (OR=3.32). Cases were more likely to have family history of alcohol (OR=1.73) and drug abuse (OR=3.61). Subjects had similar prevalences of depressive disorders, anxiety disorders or psychotic disorders. AUD suicides were more likely to meet criteria for current cocaine abuse/dependence (OR=6.64). With respect to personality disorders, AUD suicides presented higher prevalence of Antisocial Personality Disorder (OR=4.68), and were less likely to meet criteria for Avoidant (OR=0.26) and Obsessive-Compulsive Personality Disorders (OR=0.35). Impulsivity scores were higher in AUD suicides (p=0.18), as well as aggression scores (p<0.001). Results form the conditional logistic regression models showed that cocaine abuse/dependence (OR=4.20) and Antisocial Personality Disorder (OR=6.24) were associated with AUD suicide. After controlling for impulsive-aggressive behaviors, levels of aggression were the only psychopathological feature statistically different between AUD and non-AUD suicides (OR=1.28). In conclusion, higher levels of aggressive behaviors are a specific characteristic of AUD suicides. Apart from

Although the association between alcohol and pancreatic diseases has been recognized for a long time, the impact of alcohol consumption on pancreatitis and pancreatic cancer (PC) remains poorly defined. Nowadays there is not consensus about the epidemiology and the beverage type, dose and duration of alcohol consumption causing these diseases. The objective of this study was to review the epidemiology described in the literature for pancreatic diseases as a consequence of alcoholic behavior trying to understand the association between dose, type and frequency of alcohol consumption and risk of pancreatitis and PC. The majority of the studies conclude that high alcohol intake was associated with a higher risk of pancreatitis (around 2.5%-3% between heavy drinkers and 1.3% between non drinkers). About 70% of pancreatitis are due to chronic heavy alcohol consumption. Although this incidence rate differs between countries, it is clear that the risk of developing pancreatitis increases with increasing doses of alcohol and the average of alcohol consumption vary since 80 to 150 g/d for 10-15 years. With regard to PC, the role of alcohol consumption remains less clear, and low to moderate alcohol consumption do not appear to be associated with PC risk, and only chronic heavy drinking increase the risk compared with lightly drinkers. In a population of 10%-15% of heavy drinkers, 2%-5% of all PC cases could be attributed to alcohol consumption. However, as only a minority (less than 10% for pancreatitis and 5% for PC) of heavily drinkers develops these pancreatic diseases, there are other predisposing factors besides alcohol involved. Genetic variability and environmental exposures such as smoking and diet modify the risk and should be considered for further investigations.

The aim of this paper is to estimate the cumulative effect of childhood household dysfunction (CHD) on alcohol related illness and death later in life and to test the interaction between CHD and socioeconomic background. The study utilised Swedish national registers including data of a Swedish national cohort born 1973-82 (n = 872,912), which was followed from age 18 to 29-40 years. Cox regression analyses were used to calculate hazard ratios (HR) for alcohol related illness or death in young adulthood. The CHD measure consisted of seven indicators: parental alcohol/drug misuse, mental health problems, criminality, death, divorce, social assistance, and child welfare interventions. Childhood socioeconomic position (SEP) was indicated by parental occupational status. Outcomes were alcohol related inpatient hospital care, specialised outpatient care or deaths. Using the highest socioeconomic group without CHD experience as a reference, those in the same socioeconomic group with one indicator of CHD had HRs of 2.1 [95% CI: 1.7-2.5], two CHD indicators 5.6 [4.4-7.1], three or more indicators 9.4 [7.1-12.4] for retrieving inpatient care. Socioeconomic disadvantage further increased the risks-those with low socioeconomic background and three CHD indicators or more had a HR of 12.5 [10.9-14.3]. Testing for interaction suggests that the combined HRs deviates from additivity [Synergy index: 1.6, 95% CI: 1.4-1.9]. The results for outpatient care were similar, but not as pronounced. In conclusion, this Swedish national cohort study shows that childhood household dysfunction is strongly and cumulatively associated to alcohol related illness later in life and that it interacts with socioeconomic disadvantage.

Background Registered offenders are known to have a higher mortality rate, but given the high proportion of offenders with drug-addiction, particularly among offenders with a custodial sentence, higher mortality is expected. While the level of overall mortality compared to the non-criminal population is of interest in itself, we also estimate the risk of death by criminal records related to substance abuse and other types of criminal acts, and separate between those who receive a prison sentence or not. Methods Age-adjusted relative risks of death for 2000–2008 were studied in a population based dataset. Our dataset comprise the total Norwegian population of 2.9 million individuals aged 15–69 years old in 1999, of whom 10% had a criminal record in the 1992–1999 period. Results Individuals with a criminal record have twice the relative risk (RR) of death of the control group (non-offenders). Males with a record of use/possession of drugs and a prison record have an 11.9 RR (females, 15.6); males with a drug record but no prison record have a 6.9 RR (females 10.5). Males imprisoned for driving under the influence of substances have a 4.4 RR (females 5.6); males with a record of driving under the influence but no prison sentence have a 3.2 RR (females 6.5). Other male offenders with a prison record have a 2.8 RR (females 3.7); other male offenders with no prison record have a 1.7 RR (females 2.3). Conclusion Significantly higher mortality was found for people with a criminal record, also for those without any record of drug use. Mortality is much higher for those convicted of substance-related crimes: more so for drug- than for alcohol-related crimes and for women. PMID:24223171

Firearm violence frequently involves alcohol, but there are no studies of misuse of alcohol and risk for future violence among firearm owners. We examined the association between prior convictions for alcohol-related crimes, chiefly driving under the influence (DUI), and risk of subsequent arrest among 4066 individuals who purchased handguns in California in 1977. During follow-up through 1991, 32.8% of those with prior alcohol-related convictions and 5.7% of those with no prior criminal history were arrested for a violent or firearm-related crime; 15.9% and 2.7%, respectively, were arrested for murder, rape, robbery or aggravated assault. Prior alcohol-related convictions were associated with a fourfold to fivefold increase in risk of incident arrest for a violent or firearm-related crime, a relative increase greater than that seen for age, sex or prior violence. Prior convictions for alcohol-related crime may be an important predictor of risk for future criminal activity among purchasers of firearms.

One strategy to determine the contribution of individual genes to the development of complex traits and behaviors such as alcohol consumption is to reduce or completely eliminate the activity of those genes in the cells or organism under investigation and then study the effects of this modification. But how can a single specific gene be inactivated? One strategy that has been developed in recent years is the use of small, artificially generated molecules called short-interfering RNAs (siRNAs). This article briefly describes the principles of this strategy and presents some initial results obtained with this approach.

Objective To conduct a systematic review of the literature examining risk and protective factors of alcohol related negative consequences (ARNCs) among adolescents. Methods We conducted a systematic search of original empirical articles published between January 1, 1990 and June 1, 2015. The qualitative synthesis was performed using the Theory of Triadic Influence as a framework. Results Fifty-two studies were reviewed. Intrapersonal (e.g., personality traits, drinking motives and expectancies, depression), interpersonal (e.g., parental and peer alcohol use, violence exposure) and attitudinal factors (e.g., media exposure to alcohol, religiosity) influence ARNCs. Emerging evidence of new trends contributing to ARNCs include ready mixed alcohol drinks and childhood trauma and abuse. Conclusions Risk factors from all domains of influence were observed. More research is needed on protective factors and how alcohol use interacts with preventive factors in predicting ARNCs. The conceptualization of negative consequences varies significantly between studies and may impact the external validity of previous research. PMID:26871952

Health professionals’ personal health behaviors have been found to be associated with their practices with patients in areas such as smoking, physical activity and weight management, but little is known in relation to alcohol use. This review has two related strands and aims to: (1) examine health professionals’ alcohol-related health promotion practices; and (2) explore the relationship between health professionals’ personal alcohol attitudes and behaviors, and their professional alcohol-related health promotion practices. A comprehensive literature search of the Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL, British Nursing Index, Web of Science, Scopus and Science Direct (2007–2013) identified 26 studies that met the inclusion criteria for Strand 1, out of which six were analyzed for Strand 2. The findings indicate that health professionals use a range of methods to aid patients who are high-risk alcohol users. Positive associations were reported between health professionals’ alcohol-related health promotion activities and their personal attitudes towards alcohol (n = 2), and their personal alcohol use (n = 2). The findings have some important implications for professional education. Future research should focus on conducting well-designed studies with larger samples to enable us to draw firm conclusions and develop the evidence base. PMID:24366045

In a national US sample of pregnant women (n=311), we investigated the question of who becomes highly anxious about pregnancy by examining putative sociodemographic, pregnancy- and mental health-related predictors of pregnancy anxiety. We also assessed the contribution of pregnancy anxiety to the risk of significant alcohol consumption during pregnancy. English-speaking pregnant women aged 18+years were recruited online. Results indicated that sociodemographic factors (younger age, white, unmarried, lower education, lower household income, no previous children), feelings about current pregnancy (unwanted), and general anxiety (higher general and state anxiety) predicted higher pregnancy-related anxiety, whereas age, religiosity, number of weeks pregnant, unplanned pregnancy, and maternal depressive symptoms did not. Pregnancy anxiety was the single strongest predictor of alcohol drinking risk during pregnancy (p<.001, ∆R(2)=.10) a relationship that held after controlling for other significant predictors. Pregnancy anxiety also represented the strongest predictor of screening positively for drinking risk during pregnancy at the total T-ACE (an alcohol risk screener for pregnancy) level of 3+ (odds ratio 95% CI=1.61-4.14, p<.001), though not at the level of 2+ (odds ratio 95% CI=0.98-1.68, p=.07). We discuss implications for the link between maternal mental health and birth/ child outcomes.

This study contributes to the scarce research on U.S. college students studying abroad by documenting general and sexual negative alcohol-related risks and factors associated with such risk. The manner of drinking (quantity vs. frequency), predeparture expectations surrounding alcohol use while abroad, culture-related social anxiety, and perceived disparity between home and host cultures differentially predicted consequences abroad. The findings include important implications for student affairs professionals in developing study abroad–specific interventions and resources to maintain student well-being while abroad.

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.

Alcohol Myopia Theory (AMT; Steele & Josephs, 1990) purports that alcohol facilitates aggression by narrowing attentional focus onto salient and instigatory cues common to conflict situations. However, few tests of its counterintuitive prediction - that alcohol may decrease aggression when inhibitory cues are most salient - have been conducted. The present study examined whether an AMT-inspired self-awareness intervention manipulation would reduce heavy drinking men's intoxicated aggression toward women and also examined whether a relevant individual variable, locus of control, would moderate this effect. Participants were 102 intoxicated male heavy drinkers who completed a self-report measure of locus of control and completed the Taylor Aggression Paradigm (Taylor, 1967). In this task, participants administered electric shocks to, and received electric shocks from, a fictitious female opponent while exposed to an environment saturated with or devoid of self-awareness cues. Results indicated that the self-awareness manipulation was associated with less alcohol-related aggression toward the female confederate for men who reported an internal, but not an external, locus of control. Findings support AMT as a theoretical framework to inform preventative interventions for alcohol-related aggression and highlight the importance of individual differences in receptivity to such interventions.
Do predisposing and family background characteristics modify or confound the relationship between drinking frequency and alcohol-related aggression? A study of late adolescent and young adult drinkers.
Wells, Samantha; Graham, Kathryn; Speechley, Mark; Koval, John J
The present study examined whether predisposing and family background characteristics confounded (common cause/general deviance theory) or modified (conditional/interactive theory) the association between drinking frequency and alcohol-related aggression. A secondary analysis of the US National Longitudinal Survey of Youth was conducted using a composite sample of drinkers, ages 17 to 21, from the 1994, 1996, and 1998 Young Adult surveys (n=602). No evidence of confounding of the relationship between drinking frequency and alcohol-related aggression was found. In addition, predisposing characteristics did not modify the association between drinking frequency and alcohol-related aggression. However, family background variables (mother's education and any poverty) were important explanatory variables for alcohol-related aggression among males, whereas recent aggression (fights at school or work) was an important predictor for females. Overall, lack of support for the conditional/interactive and common cause theories of the alcohol and aggression relationship suggests that alcohol has an independent explanatory role in alcohol-related aggression. In addition, the gender differences found in the present study highlight the need for more gender-focussed research on predictors of alcohol-related aggression, especially among adolescents and young adults.

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.

Objectives This study examined processes linking age cohort, economic stressors, coping strategies and two drinking-related outcomes (i.e., past-month drinking and problematic drinking). Methods Structural equation models were conducted utilizing data from a national survey. Results Findings revealed the associations between economic stressors and both past-month drinking and problematic drinking were significantly greater for members of the millennial cohort compared to baby boomers. These effects are partly explained by the lesser tendency of members of the millennial cohort to use collective, politically-focused coping strategies. Discussion These findings clarify the circumstances in which age matters most for the associations among economy-related stressors, coping strategies and drinking-related outcomes. They highlight how difficult economic circumstances influence the availability of coping strategies and, in turn, alcohol consumption – and differently for younger and older age cohorts.

Introduction Harmful drinking among young people is common in Australia and many other countries. Social norms and their influence on adolescents’ alcohol consumption behaviours have received much research attention in recent years. However, there is limited understanding of how social norms related to alcohol are developed and transmitted across social networks and a specific tool that measures these constructs has yet to be developed. This paper outlines the rationale and protocol for the design and validation of a multidimensional survey instrument which measures the development and transmission pathways of alcohol-related norms among adolescents. A longer term aim is to apply the instrument in a respondent-driven sampling study with a large adolescent cohort. Methods and analysis Social Cognitive Theory (SCT) and relevant literature will guide the design of the online survey instrument. Feedback from a practitioner-based stakeholder committee, academic expert panel reviews, focus groups and interviews with adolescents aged 13–17 years in Perth, Western Australia (WA) will serve to ascertain content and face validity. A test–retest will be conducted using a purposive sample of students (n=400) at secondary schools in Perth. The instrument's psychometric properties will be analysed, including exploratory factor analyses, discriminant validity, internal consistency and test–retest reliability. Ethics and dissemination The results of this research will provide public health researchers and practitioners with a comprehensive standardised instrument to explore the characteristics of individual-level and community-level social influences and norms associated with use of alcohol by adolescents and the routes through which these norms are transmitted. The data collected by the instrument is anticipated to inform the design of youth specific interventions with the potential to reduce alcohol-related harms. The Study findings will be disseminated widely through

The central amygdala (CeA) is uniquely situated to function as an interface between stress- and addiction-related processes. This brain region has long been attributed an important role in aversive (e.g., fear) conditioning, as well as the negative emotional states that define alcohol dependence and withdrawal. The CeA is the major output region of the amygdala and receives complex inputs from other amygdaloid nuclei as well as regions that integrate sensory information from the external environment (e.g., thalamus, cortex). The CeA is functionally and anatomically divided into lateral and medial subdivisions that themselves are interconnected and populated by inhibitory interneurons and projections neurons. Neuropeptides are highly expressed in the CeA, particularly in the lateral subdivision, and the role of many of these peptides in regulating anxiety- and alcohol-related behaviors has been localized to the CeA. This review focuses on two of these peptides, corticotropin-releasing factor (CRF) and neuropeptide Y (NPY), that exhibit a high degree of neuroanatomical overlap (e.g., in CeA) and largely opposite behavioral profiles (e.g., in regulating anxiety- and alcohol-related behavior). CRF and NPY systems in the CeA appear to be recruited and/or up-regulated during the transition to alcohol dependence. These and other neuropeptides may converge on GABA synapses in CeA to control projection neurons and downstream effector regions, thereby translating negative affective states into anxiety-like behavior and excessive alcohol consumption.

This study investigates the effects of alcohol advertising on adolescent alcohol consumption. The theory of an industry response function and evidence from prior studies indicate the importance of maximizing the variance in advertising measures. Monitoring the Future (MTF) and National Longitudinal Survey of Youth 1997 (NLSY97) data are augmented with alcohol advertising, originating on the market level, for five media. The large sample of the MTF allows estimation of race and gender-specific models. The longitudinal nature of the NLSY97 allows controls for unobserved heterogeneity with state-level and individual fixed effects. Price and advertising effects are generally larger for females relative to males. Controls for individual heterogeneity yield larger advertising effects, implying that the MTF results may understate the effects of alcohol advertising. Results from the NLSY97 suggest that a 28% reduction in alcohol advertising would reduce adolescent monthly alcohol participation from 25% to between 24 and 21%. For binge participation, the reduction would be from 12% to between 11 and 8%. The past month price-participation elasticity is estimated at -0.26, consistent with prior studies. The results show that reduction of alcohol advertising can produce a modest decline in adolescent alcohol consumption, though effects may vary by race and gender.

Alcohol use and firearm ownership are risk factors for violent injury and death. To determine whether firearm ownership and specific firearm-related behaviours are associated with alcohol-related risk behaviours, the author conducted a cross-sectional study using Behavioral Risk Factor Surveillance System data for eight states in the USA from 1996 to 1997 (the most recent data available). Altogether, 15 474 respondents provided information on firearm exposure. After adjustment for demographics and state of residence, firearm owners were more likely than those with no firearms at home to have ≥5 drinks on one occasion (OR 1.32; 95% CI 1.16 to 1.50), to drink and drive (OR 1.79; 95% CI 1.34 to 2.39) and to have ≥60 drinks per month (OR 1.45; 95% CI 1.14 to 1.83). Heavy alcohol use was most common among firearm owners who also engaged in behaviours such as carrying a firearm for protection against other people and keeping a firearm at home that was both loaded and not locked away. The author concludes that firearm ownership and specific firearm-related behaviours are associated with alcohol-related risk behaviours.

The study investigated prenatal alcohol consumption and knowledge of alcohol risks and fetal alcohol syndrome among Korean women. The participants were 221 Korean women who attended the post-partum care centers in Seoul, Korea. The data included the participants' background characteristics, quantity-frequency typology, Student Alcohol Questionnaire, and a scale on the participants' knowledge of fetal alcohol syndrome. Alcohol was consumed during pregnancy by 12.7% of the participants. Of these, 60.7% drank alcohol with their spouse. A few participants reported that nurses identified their drinking habits and gave them information on alcohol consumption and fetal alcohol syndrome. Most of the participants did not have the opportunity for prenatal counseling about fetal alcohol syndrome. The knowledge level regarding alcohol risks and fetal alcohol syndrome among the participants was poor. Alcohol consumption before pregnancy was significantly related to prenatal alcohol consumption. Prenatal alcohol consumption was not related to knowledge about alcohol consumption and fetal alcohol syndrome. The assessment of alcohol consumption and counseling about alcohol are needed for pregnant women in order to prevent fetal alcohol syndrome.

This study examined how work stressors were associated with sleep quality and alcohol-related problems among U.S. Navy members over the course of deployment. Participants were 101 U.S. Navy members assigned to an Arleigh Burke-class destroyer who experienced an 8-month deployment after Operational Enduring Freedom/Operation Iraqi Freedom. Approximately 6 weeks prior to deployment, 6 weeks after deployment, and 6 months reintegration, participants completed measures that assessed work stressors, sleep quality, and alcohol-related problems. A piecewise latent growth model was conducted in which the structural paths assessed if work stressors influenced sleep quality or its growth over time, and in turn if sleep quality influenced alcohol-related problems intercepts or growth over time. A significant indirect effect was found such that increases in work stressors from pre- to postdeployment predicted decreases in sleep quality, which in turn were associated with increases in alcohol-related problems from pre- to postdeployment. These effects were maintained from postdeployment through the 6-month reintegration. Findings suggest that work stressors may have important implications for sleep quality and alcohol-related problems. Positive methods of addressing stress and techniques to improve sleep quality are needed as both may be associated with alcohol-related problems among current Navy members.
Workers at the Swedish Telephone Company participated in the present study to explore the alcohol-related expectancies for a general sample of Swedish citizens and relate these expectancies to various background factors and whether the expected effects of alcohol also were desired effects. A slightly modified version of the Alcohol Expectancy Questionnaire (AEQ) was used and data were analyzed in terms of six general factors. Results indicated that men expected more sexual enhancement than women and that high consumers expected more strong effects for all six factors than the low consumers. Men further rated both sexual enhancement, physical and social pleasure, and social assertiveness as more desirable effects than did women, and the high consumers rated all six effects as more desirable than the low consumers. Results are discussed in terms of expectancies as causes of drinking.

The number of Americans who are overweight or obese has reached epidemic proportions. Elevated weight is associated with health problems and increased medical expenditures. This paper analyzes Waves 1 and 2 of the National Epidemiological Survey of Alcohol and Related Conditions to investigate the role of alcohol consumption in weight gain. Alcohol is not only an addictive substance but also a high-calorie beverage that can interfere with metabolic function and cognitive processes. Because men and women differ in the type and amount of alcohol they consume, in the biological effects they experience as a result of alcohol consumption, and in the consequences they face as a result of obesity, we expect our results to differ by gender. We use first-difference models of body mass index (BMI) and alcohol consumption (frequency and intensity) to control for time-invariant unobservable factors that may influence changes in both alcohol use and weight status. Increasing frequency and intensity of alcohol use is associated with statistically significant yet quantitatively small weight gain for men but not for women. Moreover, the first-difference results are much smaller in magnitude and sometimes different in sign compared with the benchmark pooled cross-sectional estimates.

Objective: Personalized normative feedback (PNF) has been used extensively to reduce alcohol consumption, particularly among heavy drinkers. However, the majority of PNF studies have used only descriptive norms (real or perceived pervasiveness of a given behavior). The purpose of the current study was to explore the efficacy of PNF both with and without an injunctive message indicating approval or disapproval based on the participants’ standing relative to other students’ drinking levels. This randomized trial evaluated two brief web-based alcohol intervention conditions (descriptive-norms-feedback–only condition versus a descriptive-plus-injunctive-message condition relative to an assessment-only control condition). Method: Participants included 176 students who had reported at least one heavy drinking episode in the past month. Participants completed baseline and follow-up assessments of perceived norms and drinking. Follow-up assessments were completed at 2 weeks post-intervention by 165 (94%) participants. Results: Analyses were conducted using zero-inflated negative binomial regression models. As expected, the descriptive-norms–only condition was effective in reducing drinking among heavier baseline drinkers at follow-up relative to the control condition. However, contrary to expectations, the descriptive-plus-injunctive-message condition did not predict less drinking at follow-up. Conclusions: This study was unique in using an injunctive message as an adjunct to descriptive-norms feedback within the context of drinking. Findings highlight the need for additional research into the role of defensiveness, which may serve as an impediment to using injunctive norms/messages in interventions for problematic substance use and other potentially stigmatizing behaviors.

Objective: The purpose of this study was to establish the frequency of positive and negative alcohol-related consequences during the first year of college and to evaluate gender, race/ethnicity, time of year, alcohol use, and intoxication as predictors of consequences using frequent assessments. Method: Participants (N = 1,053; 57.5% female) completed biweekly assessments of alcohol use and positive and negative alcohol-related consequences throughout the year. Results: The majority of drinkers reported both positive and negative consequences. Having a good time and feeling less stressed were the most commonly reported positive consequences. Blackouts and getting physically sick were the most commonly endorsed negative consequences. At the weekly level, number of drinking days, drinks per drinking day, and estimated blood alcohol concentration (eBAC, reflecting intoxication) were significantly related to all consequences after controlling for demographics and time of year. Negative consequences had stronger associations with number of drinks and eBAC than positive consequences did. With each additional drink consumed on a drinking day, the incidence of negative consequences more than doubled (incidence rate ratio [IRR] = 2.34, 95% CI [2.19, 2.50]), whereas the incidence of positive consequences increased by about half (IRR = 1.51, 95% CI [1.47, 1.56]). The consequence with the largest gender difference was regretted sex, with women reporting it more often. Few racial/ethnic differences were found in report of negative consequences. Greater positive and negative consequences were endorsed at the beginning of both academic semesters. Conclusions: As number of drinks and eBAC increase, the relative odds of a negative consequence are higher than that of a positive consequence. Alcohol interventions could promote greater awareness of the likelihood of specific consequences and could highlight that positive consequences are associated with lower levels of drinking. PMID

Compared with their nonathlete peers, collegiate athletes consume higher quantities of alcohol, drink with greater frequency, and exhibit an increased propensity to engage in heavy episodic drinking (ie, binge drinking), which often may result in alcohol-related consequences. Moreover, collegiate athletes are also more likely to engage in other maladaptive lifestyle behaviors, such as participating in physical fights and riding with an intoxicated driver, and less likely to engage in protective behaviors, such as wearing a helmet while operating a motorcycle, moped, or bicycle. Taken together, these behaviors clearly pose a health risk for student-athletes and increase the likelihood that they will experience an alcohol-related unintentional injury (ARUI). An ARUI represents a risk not only to the health and well-being of collegiate athletes but also to their athletic performances, collegiate careers, and potential professional opportunities. Therefore, athletic trainers need to be equipped with the knowledge and skills to provide face-to-face brief interventions to student-athletes presenting with ARUIs and to evaluate the effect of their involvement. We address potential action items for implementation by athletic trainers.

Aim Impaired illness insight may hamper treatment outcome in patients with alcohol-related cognitive deficits. In this study, a short questionnaire for the assessment of illness insight (eg, the Q8) was investigated in patients with Korsakoff’s syndrome (KS) and in alcohol use disorder (AUD) patients with mild neurocognitive deficits. Methods First, reliability coefficients were computed and internal structure was investigated. Then, comparisons were made between patients with KS and patients with AUD. Furthermore, correlations with the Dysexecutive Questionnaire (DEX) were investigated. Finally, Q8 total scores were correlated with neuropsychological tests for processing speed, memory, and executive function. Results Internal consistency of the Q8 was acceptable (ie, Cronbach’s α =0.73). The Q8 items represent one factor, and scores differ significantly between AUD and KS patients. The Q8 total score, related to the DEX discrepancy score and scores on neuropsychological tests as was hypothesized, indicates that a higher degree of illness insight is associated with a higher level of cognitive functioning. Conclusion The Q8 is a short, valid, and easy-to-administer questionnaire to reliably assess illness insight in patients with moderate-to-severe alcohol-related cognitive dysfunction. PMID:27445476

Members of Greek-letter societies are the heaviest drinkers on college campuses, and experience more alcohol-related problems than their peers. This study reports the results of a web-based survey administered to stratified random samples of college students from ten North Carolina universities. Greek-letter status was a significant independent risk factor for increased injury (both experienced and caused to others), even after adjusting for drinking behaviors. Prevention, screening, and intervention strategies are discussed in the context of these results. PMID:22689586

The present research aimed (a) to determine whether students underestimate gender-specific descriptive normative perceptions for protective behavioral strategies; (b) to evaluate the relationships among perceived gender-specific descriptive and injunctive drinking norms and perceived gender-specific descriptive norms for protective behavioral strategies; and (c) to examine whether normative perceptions for protective behavioral strategies relate to use of these strategies when controlling for relevant drinking behavior factors (i.e., alcohol consumption, negative consequences, and attitude toward drinking behavior) and social norms factors (i.e., perceived descriptive and injunctive norms). Students (N = 666; 56.6% men) completed measures assessing drinking behavior and attitudes toward drinking, perceived descriptive and injunctive norms, perceived protective behavioral strategies, and protective behavioral strategies. Findings demonstrated that students consistently underestimated the use of strategies for the typical male student, whereas results were less consistent for the typical female student. In addition, results indicated that same-sex normative perceptions for protective behavioral strategies were associated with personal use of these strategies, even when controlling for relevant drinking behavior and social norms factors. Results stress the importance of evaluating factors that are associated with use of protective behavioral strategies. Implications for social norms preventative interventions are discussed.

Purpose. This study examines the prevalence of alcohol-related problems, the factors underlying these problems, and whether or not there is evidence of syndemic effects in a community population of southern, urban African American women. Methods. Questionnaire-based interviews were conducted with 817 women, all African American, from 80 targeted census block groups in Atlanta, Georgia. Results. Most of the alcohol users (67.8%) experienced at least one problem as a result of their alcohol (ab)use, with most women experiencing two or more such problems. Eight factors were found to be associated with experiencing more alcohol problems: being aged 30 or older, having had no recent health insurance, lower levels of educational attainment, self-identifying as lesbian or bisexual, experiencing greater amounts of childhood maltreatment, greater impulsivity, perceiving one's local community or neighborhood to be unsafe, and having a larger number of criminally involved friends. Conclusions. Drinking-related problems were prevalent in this population. Numerous factors underlie the extent to which African American women experienced problems resulting from their alcohol use. There is strong evidence of syndemic-type effects influencing drinking problems in this population, and future efforts to reduce the negative impact of alcohol (ab)use ought to consider the adoption of programs using a syndemics' theory approach.

A randomized control trial was conducted at a midsized private university in the Northeast to evaluate the short-term impact of AlcoholEdu for College 8.0, an online alcohol course for first-year students. In September 2007, 1,620 matriculated first-year students were randomly assigned to either a treatment group or an assessment-only control group. Both groups of students completed a baseline survey and knowledge test. Treatment group students finished the course, took a second knowledge test, and 30 days later completed a postintervention survey. Control group students completed the postintervention survey and knowledge test during the same time period. Compared with the control group, treatment group students reported a significantly lower level of alcohol use, fewer negative drinking consequences, and less positive alcohol-related attitudes. AlcoholEdu 8.0 had a positive impact on the first-year students' alcohol-related attitudes, behaviors, and consequences. Additional investigations of online alcohol education courses are warranted.

Objective Historically, alcohol use and related harms are more prevalent in men than in women. However, emerging evidence suggests the epidemiology of alcohol use is changing in younger cohorts. The current study aimed to systematically summarise published literature on birth cohort changes in male-to-female ratios in indicators of alcohol use and related harms. Methods We identified 68 studies that met inclusion criteria. We calculated male-to-female ratios for 3 broad categories of alcohol use and harms (any alcohol use, problematic alcohol use and alcohol-related harms) stratified by 5-year birth cohorts ranging from 1891 to 2001, generating 1568 sex ratios. Random-effects meta-analyses produced pooled sex ratios within these 3 categories separately for each birth cohort. Findings There was a linear decrease over time in the sex ratio for all 3 categories of alcohol use and related harms. Among those born in the early 1900s, males were 2.2 (95% CI 1.9 to 2.5) times more likely than females to consume alcohol, 3.0 (95% CI 1.5 to 6.0) times more likely to drink alcohol in ways suggestive of problematic use and 3.6 (95% CI 0.4 to 30.3) times more likely to experience alcohol-related harms. Among cohorts born in the late 1900s, males were 1.1 (95% CI 1.1 to 1.2) times more likely than females to consume alcohol, 1.2 (95% CI 1.1 to 1.4) times more likely to drink alcohol in ways suggestive of problematic use and 1.3 (95% CI 1.2 to 1.3) times more likely to experience alcohol-related harms. Conclusions Findings confirm the closing male–female gap in indicators of alcohol use and related harms. The closing male–female gap is most evident among young adults, highlighting the importance of prospectively tracking young male and female cohorts as they age into their 30s, 40s and beyond.

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.

Objective Using an iterative process, a series of three video scenarios were developed for use as a standardized measure for assessing women’s perception of risks for alcohol-related sexual assault (SA). The videos included ambiguous and clear behavioral and environmental risk cues. Method Focus group discussions with young, female heavy drinkers (N = 42) were used to develop three videos at different risk levels (low, moderate, and high) in Study 1. Realism, reliability, and validity of the videos were assessed using multiple methods in Studies 2 and 3. One hundred-four women were used to compare differences in risk perception across the video risk level in Study 2. In Study 3 (N = 60), we assessed women’s perceptions of the low and high risk videos under conditions of no alcohol and alcohol. Results The realism and reliability of the videos were good. Women who viewed the low risk video compared to women who viewed the moderate and high risk videos perceived less risk for SA. We found an interaction between alcohol and risk perception such that, women in the alcohol condition were less likely to perceive risk when watching the high risk video. Conclusions As the video risk level increased, women’s perception of risk increased. These findings provide convergent evidence for the validity of the video measure. Given the limited number of standardized scenarios for assessing risk perception for sexual assault, our findings suggest that these videos may provide a needed standardized measure. PMID:27747131

This paper examines whether increased consumption of tobacco and alcohol products by minority groups is a function of the target marketing campaigns directed at these groups by marketers, and whether such contributes to the perpetuation of racism. First, a description of the tobacco and alcohol consumption rates of blacks and Hispanics compared to whites is presented, including a comparative analysis of the health effects and mortality rates resulting from the consumption of tobacco and alcohol. Second, the paper examines specific marketing strategies of targeting tobacco and alcohol products to ethnic minority consumers. This is followed by a discussion of whether these practices are a deliberate strategy driven by racism or just the pursuit of profit. A framework for answering the question is provided. Finally, the paper assesses the prospects for change in the future, and analyzes specific needs for future research.

Objective This aim of this study was to characterize trends in alcohol-related hospital admissions among middle-aged and older adults from 1993 to 2010 in relation to age, gender, race, and cohort membership. Method This study utilized repeated cross-sectional data from the Nationwide Inpatient Sample. Using alcohol-related classified admissions, yearly rates and longitudinal trends of alcohol-related inpatient hospitalizations based on age, period, birth cohort, gender, and race were estimated. Results Among those aged 45 and older, admissions rose from an estimated 610,634 to more than 1,134,876, and rates of any alcohol-related diagnosis also increased from 1993 to 2010. Rates for men were consistently higher than women, and rates for Blacks were higher than Whites. Age was associated with decreasing rates, but post–World War II cohorts displayed higher rates over time. Discussion Rates of alcohol-related admissions are increasing among adults above age 45, which may be a function of cohort effects. Training the health care workforce is crucial to respond to this trend. PMID:25903980

We aim to study socioeconomic inequalities in alcohol related cancers mortality (upper aero-digestive tract (UADT) (oral cavity, pharynx, larynx, oesophagus) and liver) in men and to investigate whether the contribution of these cancers to socioeconomic inequalities in cancer mortality differs within Western Europe. We used longitudinal mortality datasets including causes of death. Data were collected during the 1990s among men aged 30–74 years in 13 European populations (Madrid, the Basque region, Barcelona, Turin, Switzerland (German and Latin part), France, Belgium (Walloon and Flemish part, Brussels), Norway, Sweden, Finland). Socioeconomic status was measured using the educational level declared at the census at the beginning of the follow-up period. We conducted Poisson regression analyses and used both relative (Relative index of inequality (RII)) and absolute (mortality rates difference) measures of inequality. For UADT cancers, the RII’s were above 3.5 in France, Switzerland (both parts) and Turin whereas for liver cancer they were the highest (around 2.5) in Madrid, France and Turin. The contribution of alcohol related cancer to socioeconomic inequalities in cancer mortality was 29–36% in France and the Spanish populations, 17–23% in Switzerland and Turin, and 5–15% in Belgium and the Nordic countries. We did not observe any correlation between mortality rates differences for lung and UADT cancers, confirming that the pattern found for UADT cancers is not only due to smoking. This study suggests that alcohol use substantially influences socioeconomic inequalities in male cancer mortality in France, Spain and Switzerland but not in the Nordic countries and nor in Belgium.

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR, and SPINK1 variants were associated with pancreatitis risk. We now report two significant genome-wide associations identified and replicated at PRSS1-PRSS2 (1×10-12) and x-linked CLDN2 (p < 1×10-21) through a two-stage genome-wide study (Stage 1, 676 cases and 4507 controls; Stage 2, 910 cases and 4170 controls). The PRSS1 variant affects susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous (or hemizygous male) CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men – male hemizygous frequency is 0.26, female homozygote is 0.07. PMID:23143602

Objective Approximately 30 million Americans present to acute care medical settings annually after incurring traumatic injuries. Posttraumatic stress disorder and depressive symptoms are endemic among injury survivors. Our paper is a replication and extension of a previous report documenting a pattern of multiple traumatic life events across patients admitted to Level I trauma centers for an alcohol-related injury. Method This study is a secondary analysis of a nationwide 20-site randomized trial of an alcohol brief intervention with 660 traumatically injured inpatients. Pre-injury trauma history was assessed using the National Comorbidity Survey trauma history screen at the 6 month time point. Results Most common traumatic events experienced by our population of alcohol positive trauma survivors were having had someone close unexpectedly die, followed by having seen someone badly beaten or injured. Of particular note, there is high reported prevalence of rape/sexual assault, and childhood abuse and neglect among physically injured trauma survivors. Additional trauma histories are increasingly common among alcohol-positive patients admitted for a traumatic injury. Conclusions Due to the high rate of experienced multiple traumatic events among acutely injured inpatients, the trauma history screen could be productively integrated into screening and brief intervention procedures developed for acute care settings.

A systematic review of the literature to assess the effectiveness of alcohol tax policy interventions for reducing excessive alcohol consumption and related harms was conducted for the Guide to Community Preventive Services (Community Guide). Seventy-two papers or technical reports, which were published prior to July 2005, met specified quality criteria, and included evaluation outcomes relevant to public health (e.g., binge drinking, alcohol-related crash fatalities), were included in the final review. Nearly all studies, including those with different study designs, found that there was an inverse relationship between the tax or price of alcohol and indices of excessive drinking or alcohol-related health outcomes. Among studies restricted to underage populations, most found that increased taxes were also significantly associated with reduced consumption and alcohol-related harms. According to Community Guide rules of evidence, these results constitute strong evidence that raising alcohol excise taxes is an effective strategy for reducing excessive alcohol consumption and related harms. The impact of a potential tax increase is expected to be proportional to its magnitude and to be modified by such factors as disposable income and the demand elasticity for alcohol among various population groups.

Higher density of alcohol outlets has been linked to increased levels of adolescent alcohol-related behaviour. Research to date has been cross-sectional. A longitudinal design using two waves of annual survey data from the Australian arm of the International Youth Development Study was used. The sample comprised 2835 individuals with average age at wave 2 of 14 years (SD=1.67; range=11-17 years). GSEM was used to examine how absolute levels of alcohol outlet density was associated with student-reported alcohol use one year later, while controlling for prior alcohol use, risk factors at wave one and changes in density over the 2 years. Adolescents' perception of alcohol availability and friends' alcohol use were tested as potential mediators of the association between alcohol outlet density and adolescent alcohol use. Elasticity modelling identified a 10% increase in overall density at wave one was associated with an approximately 17% increase in odds of adolescent alcohol consumption at wave two. Living in areas with a higher density of outlets was associated with a statistically significant increase in the likelihood of adolescents developing early age alcohol consumption.

This study investigated whether the relative allocation of discretionary monetary expenditures to alcoholic beverages versus savings (presumed to reflect relative preferences for immediate vs. delayed rewards) before quitting abusive drinking predicted natural resolution among untreated problem drinkers. Drinking, life events, income, and expenditures were assessed for the year before resolution and again 1 and 2 years later (N = 50). Compared with those who relapsed, participants who remained resolved at 2 years reported proportionally more pre-resolution discretionary expenditures on savings and less on alcohol. Income and expenditures were similar across groups. The findings support the predictive utility of this functional index of relative reward preferences that operate over variable time horizons and suggest that temporal discounting is an important process in addictive behavior change.

In June of 2002, a revision to part of the Road Traffic Act drastically increased the penalties for drinking and driving offences in Japan. Most notably, the legal blood alcohol concentration (BAC) limit for driving was lowered from 0.05 mg/ml to 0.03 mg/ml. The rationale for the new lower BAC limit was predicated on the assumption that drinking drivers will comply with the new, lower limit by reducing the amount of alcohol they consume prior to driving, thereby lowering their risk of crash involvement. This, in turn, would lead to fewer alcohol-related crashes. A key limitation of previous lower BAC evaluation research in determining the effectiveness of lower legal BAC limit policies is the assumption of population homogeneity in responding to the laws. The present analysis is unique in this perspective and focuses on the evaluation of the impact of BAC limit reduction on different segments of the population. The chief objective of this research is to quantify the extent to which lowering the legal limit of BAC has reduced male, female and teenager involvement in motor vehicle crashes in Japan since 2002. Most notably, the introduction of reduced BAC limit legislation resulted in a statistically significant decrease in the number of alcohol-impaired drivers on the road in Japan, indicating responsiveness to the legal change among adults and teenagers. In addition, this preliminary assessment appears to indicate that the implementation of 0.03 BAC laws and other associated activities are associated with statistically significant reductions in alcohol-involved motor vehicle crashes. In comparison, the rates of total crashes showed no statistically significant decline nor increase in the period following the introduction of the BAC law, indicating that the lower BAC limit only had an effect on alcohol-related crashes in Japan. The evidence suggests that the lower BAC legal limit and perceived risk of detection are the two most important factors resulting in a

Research using twins has found that much of the variability in externalizing phenotypes-including alcohol and drug use, impulsive personality traits, risky sex, and property crime-is explained by genetic factors. Nevertheless, identification of specific genes and variants associated with these traits has proven to be difficult, likely because individual differences in externalizing are explained by many genes of small individual effect. Moreover, twin research indicates that heritable variance in externalizing behaviors is mostly shared across the externalizing spectrum rather than specific to any behavior. We use a longitudinal, "deep phenotyping" approach to model a general externalizing factor reflecting persistent engagement in a variety of socially problematic behaviors measured at 11 assessment occasions spanning early adulthood (ages 18 to 28). In an ancestrally homogenous sample of non-Hispanic Whites (N = 337), we then tested for enrichment of associations between the persistent externalizing factor and a set of 3,281 polymorphisms within 104 genes that were previously identified as associated with alcohol-use behaviors. Next, we tested for enrichment among domain-specific factors (e.g., property crime) composed of residual variance not accounted for by the common factor. Significance was determined relative to bootstrapped empirical thresholds derived from permutations of phenotypic data. Results indicated significant enrichment of genetic associations for persistent externalizing, but not for domain-specific factors. Consistent with twin research findings, these results suggest that genetic variants are broadly associated with externalizing behaviors rather than unique to specific behaviors.

Rationale Alcohol use appears to decrease executive function acutely in a dose dependent manner, and lower baseline executive function appears to contribute to problematic alcohol use. However, no studies, to our knowledge, have examined the relationship between individual differences in working memory (a subcomponent of executive function) after alcohol consumption and drinking behaviors and consequences. Objectives The current study assessed the relationship between drinking behavior, alcohol-related consequences, and alcohol-induced changes in working memory (as assessed by Trails Making Test-B). Method Participants recruited from the community (n = 41), 57.3% male, mean age 39.2, took part in a three-session, within-subjects, repeated-measures design. Participants were administered a placebo, 0.4 g/kg, or 0.8 g/kg dose of alcohol. Working memory, past 30 day alcohol consumption, and consequences of alcohol use were measured at baseline; working memory was measured again after each beverage administration. Results Poorer working memory after alcohol administration (controlling for baseline working memory) was significantly associated with a greater number of drinks consumed per drinking day. Additionally, we observed a significant indirect relationship between the degree of alcohol-induced working memory decline and adverse consequences of alcohol use, which was mediated through greater average drinks per drinking day. Conclusions It is possible that greater individual susceptibility to alcohol-induced working memory decline may limit one’s ability to moderate alcohol consumption as evidenced by greater drinks per drinking day, and that this results in more adverse consequences of alcohol use.

Background Information on the economic impact of alcohol consumption can provide important evidence in supporting policies to reduce its associated harm. To date, several studies on the economic costs of alcohol consumption have been conducted worldwide. This study aims to review the economic impact of alcohol worldwide, summarizing the state of knowledge with regard to two elements: (1) cost components included in the estimation; (2) the methodologies employed in works conducted to date. Methods Relevant publications concerning the societal cost of alcohol consumption published during the years 1990-2007 were identified through MEDLINE. The World Health Organization's global status report on alcohol, bibliographies and expert communications were also used to identify additional relevant studies. Results Twenty studies met the inclusion criteria for full review while an additional two studies were considered for partial review. Most studies employed the human capital approach and estimated the gross cost of alcohol consumption. Both direct and indirect costs were taken into account in all studies while intangible costs were incorporated in only a few studies. The economic burden of alcohol in the 12 selected countries was estimated to equate to 0.45 - 5.44% of Gross Domestic Product (GDP). Conclusion Discrepancies in the estimation method and cost components included in the analyses limit a direct comparison across studies. The findings, however, consistently confirmed that the economic burden of alcohol on society is substantial. Given the importance of this issue and the limitation in generalizing the findings across different settings, further well-designed research studies are warranted in specific countries to support the formulation of alcohol-related policies.

Because of their complex social structures, behaviors, and genetic similarities to humans, nonhuman primates are useful for studying how genetic factors influence alcohol consumption. The neurobiological systems that influence addiction vulnerability may do so by acting on alcohol response, reward pathways, behavioral dyscontrol, and vulnerability to stress and anxiety. Rhesus macaques show individual differences in alcohol response and temperament, and such differences are influenced by genetic variants that are similar functionally to those present in humans. Genes at which variation moderates these phenotypes include those encoding monoamine oxidase A (MAOA-LPR), the serotonin transporter (HTTLPR), corticotropin releasing hormone (CRH-248C/T and -2232 C/G), Neuropeptide Y (NPY-1002 T/G), and the μ-opioid receptor (OPRM1 C77G). These provide opportunities for modeling how genetic and environmental factors (i.e., stress, individual's sex, or alcohol exposure) interact to influence alcohol consumption. Studies in primates may also reveal selective factors have driven maintenance or fixation of alleles that increase risk for alcohol use disorders in modern humans.

The work analyzes different aspects related to alcohol consumption among homeless people and people at risk of social exclusion. The data was gathered from a representative sample of homeless people in Madrid (n = 188) and a sample of people at risk of social exclusion (n = 164) matched in sex, age, and origin (Spaniards vs. foreigners). The results showed that homeless people present a greater consumption of alcohol and have experienced more problems derived from its consumption than people at risk of social exclusion. Most of the homeless people who had alcohol-related problems had had them prior to their homelessness, and they stated they had poorer health and had experienced a greater number of homelessness episodes. Despite the relevance of problems related to alcohol among our sample, only a small percentage of the sample had participated in treatment programs for alcohol consumption.

The discipline of behavioral economics integrates principles from psychology and economics to systematically characterize decision-making preferences. Two forms of behavioral economic decision making are of relevance to HIV risk behavior: delay discounting, reflecting preferences for immediate small rewards relative to larger delayed rewards (i.e., immediate gratification), and probability discounting, reflecting preferences for larger probabilistic rewards relative to smaller guaranteed rewards (i.e., risk sensitivity). This study examined questionnaire-based indices of both types of discounting in relation to sexual risk taking in an emergency department sample of hazardous drinkers who engage in risky sexual behavior. More impulsive delay discounting was significantly associated with increased sexual risk-taking during a drinking episode, but not general sexual risk-taking. Probability discounting was not associated with either form of sexual risk-taking. These findings implicate impulsive delay discounting with sexual risk taking during alcohol intoxication and provide further support for applying this approach to HIV risk behavior.

Background It is well established that individual difference factors modulate aggression under the acute effects of alcohol. In this investigation, we tested the hypothesis that one core dimension of psychopathy, Impulsive Antisociality, would modulate intoxicated aggression, whereas another dimension, Fearless Dominance, would not. Methods Participants were 516 young social drinkers (253 men and 263 women). Psychopathy was measured using the Psychopathic Personality Inventory (PPI; Lilienfeld and Andrews, 1996). Following the consumption of either an alcohol or a placebo beverage, aggression was measured with a task in which participants administered and received electric shocks to/from a fictitious opponent under the guise of a competitive reaction-time task. Results Hierarchical regression analyses supported our hypothesis: Impulsive Antisociality predicted aggression under alcohol, whereas Fearless Dominance did not. Conclusions Persons who tend to endorse antisocial and impulsive externalizing behaviors appear to be at greater risk for aggression under the acute influence of alcohol. PMID:22959485

Objective: Depression is often found to be comorbid with alcohol-related problems. Parental overprotection, which may be of particular importance during emerging adulthood, has been linked to internalizing symptoms in offspring. This article evaluates the impact of parenting styles and parental confidence in their offspring on an internalizing pathway to alcohol-related problems through self-esteem and depression. Method: Mediational links were tested among parenting styles (authoritative, authoritarian, permissive), parental confidence (overprotection, autonomy), self-esteem, depression, and alcohol-related problems. A two-group, multiple indicator multiple-cause structural equation model with 441 (216 female, 225 male) college students was examined. Results: Overall, having a father who was confident in his child's ability to make autonomous decisions was protective against depression for both genders. Perceptions of paternal autonomy mediated the impact of the fathers' parenting styles (authoritative, permissive) on depression for both genders. For men, parental overprotection mediated the impact of an authoritarian father on self-esteem, and self-esteem mediated the impact of parental overprotection on depression. Moreover, among men, perceptions of maternal autonomy mediated the impact of the mothers' parenting styles (authoritative, permissive) on self-esteem, and self-esteem mediated the impact of maternal autonomy on depression. Conclusions: The current pattern of findings is distinct from pathways through behavioral undercontrol with influences from the same-sex parent for both genders. These findings indicate that parenting may have differential influences on internalizing pathways to alcohol-related problems. PMID:19261233

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

Except for Quebec, all Canadian provinces have introduced administrative laws to lower the permitted blood alcohol concentration (BAC) to .05% or .04% for driving-or having the care of-a motor vehicle. Using linear mixed effects models for longitudinal data, this study evaluates the effect of administrative BAC laws on fatal alcohol related crashes and law enforcement patterns in Canada from 1987 to 2010. Results reveal a significant decrease of 3.7% (95% C.I.: 0.9-6.5%) in fatally injured drivers with a BAC level equal or greater than .05% following the introduction of these laws. Reductions were also observed for fatally injured drivers with BAC levels greater that .08% and .15%. The introduction of administrative BAC laws led neither to significant changes in the rate of driving while impaired (DWI) incidents reported by police officers nor in the probability of being charged for DWI under the Criminal Code.

This study examined race and gender differences in use of specific types of protective behavioral strategies (PBS) and the moderating effects of race and gender on the relationship between PBS use and alcohol problems, controlling for alcohol use, among a large sample of Asian, Black, and White college drinkers. There were significant racial and gender differences in the types of PBS used. Moderation analyses indicated that PBS were more protective for women than men against experiencing alcohol-related problems. There were no significant race effects or race-by-gender interaction effects on alcohol problems. Implementing PBS may be beneficial for all college students. PMID:26114577

Background and Aim Alcohol-related liver disease (ALD) is mediated in part by insulin resistance. Attendant dysregulation of lipid metabolism increases accumulation of hepatic ceramides that worsen insulin resistance and compromise the structural and functional integrity of the liver. Insulin and insulin growth factor (IGF) stimulate aspartyl-asparaginyl-β-hydroxylase (AAH), which promotes cell motility needed for structural maintenance and remodeling of the liver. AAH mediates its effects by activating Notch, and in ALD, insulin/IGF signaling, AAH, and Notch are inhibited. Method To test the hypothesis that in ALD, hepatic ceramide load contributes to impairments in insulin, AAH, and Notch signaling, control and chronic ethanol-fed adult Long–Evans rats were treated with myriocin, an inhibitor of serine palmitoyl transferase. Livers were used to assess steatohepatitis, insulin/IGF pathway activation, and expression of AAH–Notch signaling molecules. Results Chronic ethanol-fed rats had steatohepatitis with increased ceramide levels; impairments in signaling through the insulin receptor, insulin receptor substrate, and Akt; and decreased expression of AAH, Notch, Jagged, Hairy–Enhancer of Split-1, hypoxiainducible factor 1α, and proliferating cell nuclear antigen. Myriocin abrogated many of these adverse effects of ethanol, particularly hepatic ceramide accumulation, steatohepatitis, and impairments of insulin signaling through Akt, AAH, and Notch. Conclusions In ALD, the histopathology and impairments in insulin/IGF responsiveness can be substantially resolved by ceramide inhibitor treatments, even in the context of continued chronic ethanol exposure.

Ecological momentary assessment (EMA) has afforded several important advances in the field of alcohol research, including testing prominent models of alcohol abuse etiology in "high resolution." Using high-tech methods for signaling and/or assessment, such as mobile electronic diaries, personal data assistants, and smartphones, EMA approaches potentially can improve understanding of precipitants of drinking, drinking patterns, and consequences. For example, EMA has been used to study complex drinking patterns and dynamic predictors of drinking in near-real time. Compared with other methods, EMA can better sample and capture changes in these phenomena that occur in relatively short time frames. EMA also has several potential applications in studying the consequences of alcohol use, including physical, interpersonal, behavioral, and legal problems. However, even with all these potential capabilities, EMA research in the alcohol field still is associated with some limitations, including the potential for measurement reactivity and problems with acceptability and compliance. Despite these limitations, electronically based EMA methods are versatile and are capable of capturing data relevant to a variety of momentary influences on both alcohol use and consequences. Therefore, it will be exciting to fully realize the potential of future applications of EMA technologies, particularly if the associated costs can be reduced.

Chronic excessive alcohol intake results in alcohol-related brain damage. Many previous reports have documented alcohol-related global or local brain shrinkage or diffusional abnormalities among alcoholics and heavy to moderate drinkers; however, the influence of relatively low levels of alcohol consumption on brain structural or diffusional abnormality is unclear. We investigated structural or diffusional abnormalities related to lifetime alcohol consumption (LAC) using voxel-based morphometry (VBM) among Japanese non-alcohol-dependent individuals (114 males, 97 females). High-resolution three-dimensional magnetic resonance images and diffusion tensor imaging were acquired in all subjects. The collected images were normalized, segmented, and smoothed using SPM 5. Gray matter volume (GMV) and white matter volume (WMV) were normalized for each total intracranial volume (TIV), and partial correlation coefficients were estimated between normalized GMV or WMV and lifetime alcohol consumption (LAC) adjusted for age. To investigate regional GMV or WMV abnormalities related to LAC, multiple regression analyses were performed among regional GMV or WMV and LAC, age, and TIV. To investigate subtle regional abnormalities, multiple regression analyses were performed among fractional anisotropy (FA) or mean diffusivity (MD), and LAC and age. No LAC-related global or regional GMV or WMV abnormality or LAC-related regional FA abnormality was found among male or female subjects. Significant LAC-related MD increase was found in the right amygdala among female subjects only. The current results suggest female brain vulnerability to alcohol, and a relation between subtle abnormality in the right amygdala and alcohol misuse.

The aim of this study was to gather enough data in order to formulate theory- and research-based recommendations to policy makers with the intention of decreasing the number of alcohol-related accidents and victims on Croatian roads. The data on the injured traffic participants and the share of participants under the influence of alcohol were collected from the police reports of the Traffic Police Department, Ministry of the Interior, written at the scene of the respective accidents. This documentation was then processed by descriptive epidemiology and analysed through a four-year period, before and after the passing of the New Road Traffic Safety Act in the Republic of Croatia, on 20 August 2004. In the first six months of 2005, after the passing of the Act, there were 3,275 accidents caused by the motorists under the influence of alcohol (12.5% of all the accidents), with 64 persons killed. Only 5 fatalities (8%) were caused by the drivers with measured blood alcohol concentration of up to 0.5 per thousand. As much as 27 fatalities (42%) were caused by the drivers with measured more than 1.5 per thousand, while half of the fatalities, 32 (50%), were caused by drivers with 0.5-1.5 per thousand. In this period, more than 451,000 violations were recorded, whereas in the same period of the previous year, the number of violations was about 519,000. A reduction of the total number of accidents is the result of the new regulation provision, according to which the incidents without human victims do not have to be reported to the police. The number of traffic accidents caused by drivers under the influence of alcohol had increased by some dozen per cents, namely: 2005 - 6,219 persons, 2006- 6,590 persons, noting that in 2006 one less person was killed (123) compared to 2005. In 2005, drivers with alcohol concentration of 0-0.5 per thousand caused 1,096 accidents, with 14 fatalities, whereas in 2006 there were 1,164 accidents with 9 fatalities. A total of 2,314 accidents
Parents influence adolescent drinking behavior, but to what extent does this association diminish with age, however? The cross-sectional data was drawn from the Scania drug use survey 2007, consisting of 4,828 secondary education students in the 9th and 11th grade. The age- and gender-adjusted findings indicate that having parents who are consenting to alcohol use (OR 1.4), having been provided with alcohol by one's parents (OR 1.8), having parents with an authoritarian (OR 1.5) or neglectful (OR 2.1) parenting style, and having parents who both have a university degree (OR 1.3) were factors significantly associated with monthly heavy episodic drinking. These findings lead to the conclusion that parenting styles as well as parental attitudes and behaviors are important throughout the high school years. Thus, prevention targeting parents should emphasize both these domains.

Sleep disturbances are common among alcohol-dependent individuals and are often associated with relapse. The utility of behavioral therapies for sleep disturbances, including cognitive-behavioral therapy for insomnia (CBT-I), among those with alcohol-related disorders is not well understood. This review systematically evaluates the evidence of CBT-I and related behavioral therapies applied to those with alcohol-related disorders and accompanying sleep disturbances. A search of four research databases (PubMed, PsycINFO, Embase, and CINAHL Plus) yielded six studies that met selection criteria. Articles were reviewed using Cochrane’s Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) scoring system. A majority of the studies demonstrated significant improvements in sleep efficiency among behavioral therapy treatment group(s), including but not limited to CBT-I. While behavioral sleep interventions have been successful in varied populations, they may not be utilized to their full potential among those with alcohol-related disorders as evidenced by the low number of studies found. These findings suggest a need for mixed-methods research on individuals’ sleep experience to inform interventions that are acceptable to the target population. PMID:25288884

It has been suggested that alcohol ingestion facilitates escalatory processes in aggressive interactions. The present study examined interaction patterns in intoxicated, sober and mixed dyads. Thirty pairs of men college students were randomly assigned to these conditions. Subjects who received alcohol received .964 g of absolute alcohol per kg of body weight. At the beginning of each trial in a reaction-time competition, each member of the dyad selected the shock level that he wanted his opponent to receive if the opponent was slower on the trial. Further, each member was informed by feedback lights of the shock level that his opponent had selected for him. The results indicated that the intoxicated dyads selected higher shock levels than did the sober dyads. Mixed dyads tended to select lower shock levels than intoxicated dyads but higher shock levels than sober dyads. However, these differences were not statistically significant. Additionally, intoxicated dyads escalated in aggression over the first block of six trials, whereas neither sober nor mixed dyads evidenced such an escalation. One interpretation of these findings is that the cognitive disruption caused by the alcohol interfered with the subjects' ability to evaluate the consequences of their behavior and to interpret the behavior of their opponents. A second interpretation is that, because of the expectancy effects associated with alcohol consumption, intoxicated dyads did not feel constrained to a nonaggressive stance. Finally, the value of the dyadic-interaction paradigm in the study of alcohol-related violence was discussed.

A relatively common stop codon (Q20*) was identified in the serotonin 2B receptor gene (HTR2B) in a Finnish founder population in 2010 and it was associated with impulsivity. Here we examine the phenotype of HTR2B Q20* carriers in a setting comprising 14 heterozygous HTR2B Q20* carriers and 156 healthy controls without the HTR2B Q20*. The tridimensional personality questionnaire, Brown–Goodwin lifetime aggression scale, the Michigan alcoholism screening test and lifetime drinking history were used to measure personality traits, impulsive and aggressive behavior, both while sober and under the influence of alcohol, and alcohol consumption. Regression analyses showed that among the HTR2B Q20* carriers, temperamental traits resembled a passive-dependent personality profile, and the presence of the HTR2B Q20* predicted impulsive and aggressive behaviors particularly under the influence of alcohol. Results present examples of how one gene may contribute to personality structure and behaviors in a founder population and how personality may translate into behavior. PMID:26575222

Stroke is an international health problem with high associated human and economic costs. The mortality rate from stroke in Russia is one of the highest in the world. Risk factors identification is therefore a high priority from the public health perspective. Epidemiological evidence suggests that binge drinking is an important determinant of high stroke mortality rate in Russia. The aim of the present study was to estimate the premature stroke mortality attributable to alcohol abuse in Russia on the basis of aggregate-level data of stroke mortality and alcohol consumption. Age-standardized sex-specific male and female stroke mortality data for the period 1980-2005 and data on overall alcohol consumption were analyzed by means ARIMA time series analysis. The results of the analysis suggest that 26.8% of all male stroke deaths and 18.4% female stroke deaths in Russia could be attributed to alcohol. The estimated alcohol-attributable fraction for men ranged from 16.2% (75+ age group) to 57,5% (30-44 age group) and for women from 21.7% (60-74 age group) and 43.5% (30- 44 age group). The outcomes of this study provide support for the hypothesis that alcohol is an important contributor to the high stroke mortality rate in Russian Federation. Therefore prevention of alcohol-attributable harm should be a major public health priority in Russia. Given the distribution of alcohol-related stroke deaths, interventions should be focused on the young and middle-aged men and women.
Background Alcohol is a major preventable cause of injury, disability and death in young people. Large numbers of young people with alcohol-related injuries and medical conditions present to hospital emergency departments (EDs). Access to brief, efficacious, accessible and cost effective treatment is an international health priority within this age group. While there is growing evidence for the efficacy of brief motivational interviewing (MI) for reducing alcohol use in young people, there is significant scope to increase its impact, and determine if it is the most efficacious and cost effective type of brief intervention available. The efficacy of personality-targeted interventions (PIs) for alcohol misuse delivered individually to young people is yet to be determined or compared to MI, despite growing evidence for school-based PIs. This study protocol describes a randomized controlled trial comparing the efficacy and cost-effectiveness of telephone-delivered MI, PI and an Assessment Feedback/Information (AF/I) only control for reducing alcohol use and related harm in young people. Methods/design Participants will be 390 young people aged 16 to 25 years presenting to a crisis support service or ED with alcohol-related injuries and illnesses (including severe alcohol intoxication). This single blinded superiority trial randomized young people to (i) 2 sessions of MI; (ii) 2 sessions of a new PI or (iii) a 1 session AF/I only control. Participants are reassessed at 1, 3, 6 and 12 months on the primary outcomes of alcohol use and related problems and secondary outcomes of mental health symptoms, functioning, severity of problematic alcohol use, alcohol injuries, alcohol-related knowledge, coping self-efficacy to resist using alcohol, and cost effectiveness. Discussion This study will identify the most efficacious and cost-effective telephone-delivered brief intervention for reducing alcohol misuse and related problems in young people presenting to crisis support

Background: In movies, alcohol-related cues are frequently depicted and there is evidence for a link between movie alcohol cues and immediate alcohol consumption. Less is known about factors influencing immediate effects movie alcohol exposure on drinking. The exertion of self-control is thought to be important in avoiding or resisting certain temptations. Aims: The aim of the present study was to assess the immediate effects of movie alcohol portrayals on drinking of male social drinkers and to assess the moderating role of self-control in this relation. It was hypothesized that participants would drink more when exposed to movie alcohol portrayals and that especially participants with low self-control would be affected by these portrayals. Methods: A between-subjects design comparing two movie conditions (alcohol or no portrayal of alcohol) was used, in which 154 pairs of male friends (ages 18–30) watched a 1-h movie in a semi-naturalistic living room setting. Their alcohol consumption while watching was examined. Participants completed a questionnaire assessing self-control as well as their self-reported weekly alcohol use. A multivariate regression analysis was conducted to test the effects of movie condition on alcohol comsumption. Results: Self-control moderated the relation between movie condition and alcohol consumption. Assignment to the alcohol movie condition increased alcohol consumption during the movie for males with high self-control but not for males with low self-control. Conclusion: Viewing a movie with alcohol portrayals can lead to higher alcohol consumption in a specific sample of young men while watching a movie. PMID:25691873

The purpose of this study was to document preliminary findings of the association between posttraumatic stress disorder (PTSD), mental health service use, and alcohol related health visits among veterans following 2004-2005 Florida hurricane seasons. A retrospective review of the Veterans Health Administration Medical SAS Outpatient Dataset was conducted to identify veterans residing in Florida during the 2004-2005 hurricane seasons with a history of PTSD and/or PTSD and a substance use disorder. It was found that veterans with PTSD residing in counties affected by hurricanes demonstrated an immediate 28 % increase in use of mental health services following hurricane landfall versus veterans residing in non-hurricane affected counties (+28.0 vs. -6.5 %, p = 0.001). Additionally, veterans residing in affected counties were found to use more group psychotherapy treatment sessions overall (30.3 vs. 27.2 %, p = 0.001). Of note, veterans with PTSD experienced a -0.16 per month (p = 0.114) decrease in alcohol related visits following the 2004 hurricane season. These findings provide insight into the mental health needs of veterans with PTSD following a disaster and can inform delivery of services to veterans with PTSD and alcohol related issues in disaster prone areas.

Toxicity of some legally sold alcoholic beverages has contributed to enhanced mortality in Russia since 1990. Widespread drunkenness during the early 1990s facilitated privatization of economy: workers and some intelligentsia did not oppose privatizations because of drunkenness and involvement in illegal activities. Apparently, alcohol consumption and heavy binge drinking have been decreasing in Russia since approximately the last decade. Exaggeration of alcohol-related problems tends to veil shortages of the health care system. There are motives to exaggerate consumption of nonbeverage alcohol in order to veil the problem of toxicity of some legally sold beverages. It is essential to distinguish between legally and illegally sold rather than between recorded and unrecorded alcohol because sales of poor-quality alcoholic beverages in legally operating shops and kiosks occurred generally with knowledge of authorities.

We developed a time- and cost-effective multiplex allele-specific polymerase chain reaction (AS-PCR) method based on the two-step PCR thermal cycles for genotyping single-nucleotide polymorphisms in three alcoholism-related genes: alcohol dehydrogenase 1B, aldehyde dehydrogenase 2 and μ-opioid receptor. Applying MightyAmp(®) DNA polymerase with optimized AS-primers and PCR conditions enabled us to achieve effective and selective amplification of the target alleles from alkaline lysates of a human hair root, and simultaneously to determine the genotypes within less than 1.5 h using minimal lab equipment.

Background Underage drinking is a prevalent risk behavior and common public health problem. Research shows that alcohol abuse not only affects the quality of life of drinkers themselves. The problems resulting from underage drinking pose substantial costs to society as well. The proposed study will address underage drinking with the use of an Internet campaign, which is a cost-effective way of tackling the problem. Objective The aims of this study are to test the effectiveness of an online quiz competition in changing adolescents’ alcohol-related attitudes and behavior and to explore the feasibility of using Internet viral marketing to reach a significant number of adolescents. Methods The study will constitute a cluster randomized controlled trial for 20 secondary schools (6720 Grade 7-9 students). Schools will be randomized to intervention or control arm with equal likelihood. Students in intervention schools will be invited to take part in the Internet campaign, whereas those in control schools will receive relevant promotional leaflets. Results Alcohol-related attitude and behavior will be the primary outcome measures. The results of the proposed study will provide evidence on the efficacy of an Internet intervention in modifying adolescents’ attitudes and behavior and guide further investigation into the prevention of and intervention in such risk behaviors as underage drinking. The project was funded July 2015, enrollment started September 2015, and results are expected July 2017. Conclusions With the Internet increasingly being recognized as a practical and cost-effective platform for health information delivery, the proposed Internet-based intervention is expected to be more effective in altering adolescents’ alcohol-related attitudes and behaviors than traditional health promotion.

To investigate the alcohol consumption in later life in Brazil and its association with socio-demographic characteristics. This study was a cross-sectional analysis of nationally representative survey data. A multistage cluster sampling procedure was used to select 3007 individuals of 14 years of age and older from the Brazilian household population. In this study we analyzed data from all 400 participants who were over 60 years old. Alcohol Abuse and Dependence Syndrome was established according to DSM-IV and Risky Drinking was defined in two ways: heavy drinkers (>7 drinks/week) and as binge drinkers (>3 drinks/one occasion). Twelve percent of participants reported heavy drinking behavior while 10.4% and 2.9% were binge drinkers and alcohol dependent respectively. In the adjusted logistic regression only gender was associated with heavy drinking behavior. Males, the youngest and the wealthiest were more likely to report binge drinking behaviors. In conclusion, alcohol related-problems are common but under recognized among older adults. Health professionals should be aware that common definitions of alcohol abuse and dependence may not apply as readily to older people, who have had biological changes for alcohol tolerance and its effects on the Central Nervous System.

Any use of alcohol in the years following liver transplantation (LTX) approaches 50% of patients transplanted for alcoholic liver disease (ALD). We collected detailed prospective data on alcohol consumption following LTX for ALD to investigate ongoing patterns of use. Using trajectory modeling we identified four distinct alcohol use trajectories. One group had minimal use over time. Two other groups developed early onset moderate to heavy consumption and one group developed late onset moderate use. These trajectories demonstrate that alcohol use varies based on timing of onset, quantity, and duration. Using discriminant function analysis, we examine characteristics of recipient’s pre-LTX alcohol histories and early post-LTX psychological stressors to identify the profile of those at risk for these specific trajectories. We discuss the relevance of these findings to clinical care and preliminarily to outcomes. PMID:20726963

Objective: Although the concepts of harmonious and obsessive passion have been productive in explaining why people eagerly engage in such activities as sports, Internet use, and gambling, previous research has not yet extended these models to explain alcohol and marijuana use among college students. The current research was conducted to clarify the relationships among harmonious and obsessive passion, alcohol and marijuana use, and negative consequences. Method: Two studies were conducted using online assessments. In Study 1, 748 heavy drinking college students (58% female) were recruited and completed measures of passion for drinking alcohol, alcohol use, and alcohol-related negative consequences. In Study 2, 352 regular marijuana-using students (54% female) were recruited and completed assessments of marijuana passion, marijuana use, and marijuana-related consequences. Results: Study 1 found that among heavy drinking college students, harmonious passion was a stronger predictor of increased consumption than was obsessive passion, whereas obsessive passion was a stronger predictor of alcohol-related problems than was harmonious passion. Study 2 revealed similar findings with regard to harmonious passion predicting marijuana consumption; however, unlike Study 1, no significant difference between the passions was found in predicting marijuana-related problems. Conclusions: This research provides a novel perspective on motivation for alcohol and marijuana use. Findings suggest that understanding the locus of young adults’ passion for substance use may be helpful in identifying those who are likely to develop a substance use disorder and therefore may be the most in need of assistance and intervention.

The aim of this study was to analyze the relationship of levels of self esteem and alcohol consumption in adolescents, by carrying out a transversal, descriptive study, in a college of nursing of Queretaro in Mexico, in the month of July 2008, with a sample of 109 adolescents, between 17 and 20 years old. For attainment of the data two instruments were applied: AUDIT and the Rosemberg self esteem scale. The majority of the participating adolescents had high self esteem (94.5%) and none presented low self esteem. Of the adolescents in the study 80.7% did not consume alcohol hazardously. It was concluded that the adolescents presented high self esteem and low alcohol consumption. Therefore, it is necessary to implement preventive programs related to alcohol consumption and to identify the protective factors to guarantee the maintenance of healthy habits for the adolescents.

Background Previous research has reported a significant genetic correlation between heaviness of alcohol consumption and alcohol dependence (AD), but this association might be driven by the influence of AD on consumption rather than the reverse. We test the genetic overlap between AD symptoms and a heaviness of consumption measure among individuals who do not have AD. A high genetic correlation between these measures would suggest that a continuous measure of consumption may have a useful role in the discovery of genes contributing to dependence risk. Methods Factor analysis of 5 alcohol use measures was used to create a measure of heaviness of alcohol consumption. Quantitative genetic analyses of interview data from the 1989 Australian Twin Panel (n=6257 individuals; M=29.9 years) assessed the genetic overlap between heaviness of consumption, DSM-IV AD symptoms, DSM-IV AD symptom clustering, and DSM-IV alcohol abuse. Results Genetic influences accounted for 30–51% of the variance in the alcohol measures and genetic correlations were 0.90 or higher for all measures, with the correlation between consumption and dependence symptoms among non-dependent individuals estimated at 0.97 (95% CI: 0.80–1.00). Conclusions Heaviness of consumption and AD symptoms have a high degree of genetic overlap even among non-dependent individuals in the general population, implying that genetic influences on dependence risk in the general population are acting to a considerable degree through heaviness of use, and that quantitative measures of consumption will likely have a useful role in the identification of genes contributing to AD.

The relationship between alcohol intake and colour discrimination capacity was examined among 136 persons of whom 16 were undergoing treatment in a detoxification centre. Current weekly alcohol consumption (or prior to treatment for those in the centre) was obtained with a detailed questionnaire, which divided week and weekend drinking into types of alcohol (beer, wine, spirits). Alcohol consumption varied from 0-5824 g/week; median: 266 g/week. Qualitative and quantitative assessment of acquired dyschromatopsia was obtained with a colour arrangement test, the Lanthony D-15 desaturated panel. In all age categories, the prevalence of dyschromatopsia increased with alcohol intake. Moreover, all the heavy drinkers (greater than 751 g/week) presented a certain degree of dyschromatopsia, whether or not they were undergoing treatment for alcoholism in a detoxification centre. Colour loss was primarily in the blue-yellow range; however, 4 of the 16 persons from the detoxification centre presented complex dyschromatopsia patterns including red-green loss. This raises the question of possible progressive deterioration. Multiple regression analysis showed that colour vision loss was significantly related to both age (p less than 0.001) and alcohol intake (p less than 0.01). These results underline the importance of taking into account the contribution of alcohol consumption in studies on acquired dyschromatopsia.

A few reports show that consumption of spirits and of wine correlate with elevated plasma total homocysteine (tHcy), which is associated with the risk of cardiovascular disease. We analyzed the relation between tHcy and current daily ethanol consumption cross-sectionally in middle-aged Japanese men (n = 974, age 51-59 years). Plasma tHcy was positively associated with consumption of whiskey but not with consumption of shochu (Japanese spirits), sake, beer, or wine. Odds ratios of an increase in daily intake of 30 ml ethanol (approximately 1 standard deviation) for hyperhomocysteinemia (>14.0 micromol/l) were 2.58 (95% confidence interval, 1.29-5.14) for whiskey, 1.08 (0.78-1.50) for shochu, 0.99 (0.59-1.66) for sake, 0.98 (0.58-1.63) for beer, and 1.70 (0.31-9.50) for wine in a multivariate logistic regression analysis adjusted for the daily number of cigarettes smoked, physical activity, vegetable consumption, and serum creatinine levels. After inclusion of plasma folate and vitamin B12 in the multivariate analysis model, the association between whiskey ethanol consumption and hyperhomocysteinemia remained significant with odds ratio of 2.79 (1.36-5.72). These results suggest that whiskey consumption correlates with hyperhomocysteinemia independently of plasma folate or vitamin B12 or lifestyle factors in the population studied.

Maternal alcohol consumption during pregnancy is a significant field of scientific exploration primarily because of its negative effects on the developing fetus, which is specifically defined as fetal alcohol spectrum disorders. Though the effects on the mother are less explored compared with those on the fetus, alcohol produces multiple effects on the maternal vascular system. Alcohol has major effects on systemic hemodynamic variables, endocrine axes, and paracrine factors regulating vascular resistance, as well as vascular reactivity. Alcohol is also reported to have significant effects on the reproductive vasculature including alterations in blood flow, vessel remodeling, and angiogenesis. Data presented in this review will illustrate the importance of the maternal vasculature in the pathogenesis of fetal alcohol spectrum disorders and that more studies are warranted in this field.

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.

Situational drinking motives (i.e., motives specific to the drinking situation) as well as respondent-level drinking motives (i.e., usual drinking motives across drinking situations) were examined in terms of their relations with aggression experienced by university students. Secondary, multi-level analyses were conducted on the Canadian Campus Survey (CCS), a national survey of 40 Canadian universities conducted between March 1 and April 30, 2004 (N=6,282). For their three most recent drinking events, students reported their motive for drinking (i.e., situational motive) and whether they had an argument/fight. Respondent-level drinking motives were computed by averaging motives across drinking events. Drinking to cope at the situational-level increased the likelihood of aggression. Respondent-level enhancement motives also increased the risk of aggression. Aesthetic motives were important at both situational and respondent levels decreasing the risk for alcohol-related aggression. Gender did not moderate these relations. These results suggest that prevention programming might benefit from a focus on altering drinking motives, or their underlying causes, in order to reduce alcohol-related aggression among young adults.

The reliable measurement of quality of life (QoL) presents a challenge in individuals with alcohol-related brain damage. This study investigated vagally mediated heart rate variability (vmHRV) as a physiological predictor of QoL. Self- and proxy ratings of QoL and dysexecutive symptoms were collected once, while vmHRV was repeatedly assessed over a 3-week period at weekly intervals in a sample of nine alcohol-related brain damaged patients. We provide robustness checks, bootstrapped correlations with confidence intervals, and standard errors for mean scores. We observed low to very low heart rate variability scores in our patients in comparison to norm values found in healthy populations. Proxy ratings of the QoL scale “subjective physical and mental performance” and everyday executive dysfunctions were strongly related to vmHRV. Better proxy-rated QoL and fewer dysexecutive symptoms were observed in those patients with higher vmHRV. Overall, patients showed low parasympathetic activation favoring the occurrence of dysfunctional emotion regulation strategies. PMID:27616894

Ethanol associated addictive behaviors are governed by a combination of multiple gene action (polygenic or quantitative trait) and environmental factors. We produced F2 progeny from F1 crosses derived from the alcohol-preferring Fawn-Hooded (FH/Wjd) rat strain and the alcohol-nonpreferring ACI/N strain. We compared different phenotypes related to alcohol intake in more than 600 F2 progeny. We found that female rats had significantly higher mean voluntary and forced ethanol, water, saccharin and total fluid intakes than male rats. Therefore, we compared these measures in the top 15th percentile with those in bottom 15th percentile of the F2 total ethanol intake distribution separately for males and females. The two tail comparison of means showed that only the trait of alcohol preference differed significantly in both males and females, suggesting that alcohol preference is closely related to alcohol intake. Because of the detailed information about the F1 parents of the F2 progeny, it was possible to determine parental effects. For swim test immobility, for example, the F2 progeny derived from FA(m)/FA(f) parents (ACI maternal inheritance) had the lowest mean value of 130s while the F2 progeny from AF/AF parents (FH maternal inheritance) had the highest mean value of 157s (p<0.005). The F2 progeny derived from FA/AF parents (FH maternal inheritance) showed higher mean values of forced alcohol intake than FA/FA parents (FH paternal inheritance) (6.58 and 6.36g/kg/day, respectively) suggesting that the FH mother had a significantly (p<0.0001) greater effect on forced alcohol intake than the FH father. It is concluded from these analyses that alcohol-related phenotypes are segregating independently and may be influenced by maternal and sex factors.

We used the theory of planned behaviour (TPB) to investigate factors associated with alcohol consumption among university students, and to examine whether general or alcohol-specific health knowledge acts as a moderator in the relationship between elements of the theory and drinking behaviour. Participants were 258 Australian undergraduate university students (79% female) who completed an online questionnaire, assessing the constructs of interest. The hypothesis that intentions and behaviour would be successfully predicted using the theory was generally supported. Little evidence for the moderating effect of knowledge on the TPB variables was observed, although both general and alcohol-specific health knowledge moderated the relationship between intentions and behaviours. Contrary to expectation, more accurate knowledge strengthened this relationship. Further work is necessary to investigate the role of knowledge in limiting alcohol-related harms.

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.

Background Hispanics have much higher cirrhosis mortality rates than non-Hispanic Blacks and Whites. Although heavy alcohol use and hepatitis C virus (HCV) infection are two major risk factors for cirrhosis, no studies have systematically assessed the contribution of alcohol- and HCV-related cirrhosis deaths to the total cirrhosis mortality for Hispanics as a whole and its variations across Hispanic subgroups. To fill this gap, the current study presents the latest data on total cirrhosis mortality as well as its component alcohol- and HCV-related cirrhosis mortality for all Hispanics and for Hispanic subgroups. Methods The multiple-cause approach was used to analyze data from the U.S. Multiple Cause of Death Data Files for 28,432 Hispanics and 168,856 non-Hispanic Whites (as a comparison group) who died with cirrhosis as the underlying or a contributing cause during 2000–2004. Four major Hispanic subgroups were defined by national origin or ancestry, including Mexicans, Puerto Ricans, Cubans, and Other Hispanics. The cirrhosis deaths were divided into four distinctive cause-of-death categories: alcohol-related, HCV-related, both alcohol- and HCV-related, and neither alcohol- nor HCV-related. Age-adjusted total cirrhosis death rates and percentage shares of the cause-specific categories were compared across Hispanic subgroups and non-Hispanic Whites. Results Compared with non-Hispanic Whites, all Hispanic subgroups except Cubans had much higher cirrhosis mortality. The age-adjusted total cirrhosis death rates were twice as high for Puerto Ricans and Mexicans as for non-Hispanic Whites. Alcohol-related and HCV-related cirrhosis death rates also were higher for most Hispanic subgroups than for non-Hispanic Whites. Conclusions Heavy alcohol use and hepatitis C viral infection are two important factors contributing to the high cirrhosis mortality among Hispanics. However, their relative contributions to total cirrhosis mortality varied by gender and Hispanic subgroup

Alcohol - related violence among Australian Aboriginal and Torres Strait Islanders (also called as "Indigenous") is a major public health concern in Northern Territory of Australia. There is dearth of epidemiological data that link three contributing epidemics: alcohol misuse, violence, and trauma in the Northern Territory. In this review, we aimed to concentrate on how these epidemics intersect among the Indigenous people in the Northern Territory. In our descriptive review, we have searched published papers, publicly available government and health department reports web sites reporting relevant data on these three risk factors in the Northern Territory. The high rate of family and domestic violence and assaults in the Australian Territory indicates an increased correlation with high risk alcohol use compared to unintentional injuries. Heavy drinking pattern and harmful use of alcohol among Indigenous people are more likely to be associated with the incidence of violent assaults and physical injuries in the Northern Territory. We are trying to emphasize our understanding of co-occurring risk factors on the alcohol - violence relationship and urging a need for interventional approaches to reduce the public health issues in the Northern Territory.

Using panel data from Waves 1 and 2 of the NESARC, we estimate gender-specific effects of changes in employment status on overall alcohol consumption, binge drinking episodes, and a diagnosis of alcohol abuse and/or dependence. We employ various fixed-effects models to address potential bias from unobserved and time-invariant individual heterogeneity. All results show a positive and significant effect of unemployment on drinking behaviors and the findings are robust to numerous sensitivity tests. Perhaps macroeconomic policy decisions intended to stimulate the economy during economic downturns should also consider the avoided personal costs and externalities associated with alcohol misuse.

Alcohol dependence is correlated with a wide spectrum of medical, psychological, behavioral, and social problems. Acute alcohol abuse causes damage to and functional impairment of several organs affecting protein, carbohydrate, and fat metabolism. Mitochondria participate with the conversion of acetaldehyde into acetate and the generation of increased amounts of NADH. Prenatal exposure to ethanol during fetal development induces a wide spectrum of adverse effects in offspring, such as neurologic abnormalities and pre- and post-natal growth retardation. Antioxidant effects have been described due to that alcoholic beverages contain different compounds, such as polyphenols as well as resveratrol. This review analyzes diverse topics on the alcohol consumption effects in several human organs and demonstrates the direct participation of mitochondria as potential target of compounds that can be used to prevent therapies for alcohol abusers.

Studies of the neurobiological predisposition to consume alcohol (ethanol) and to transition to uncontrolled drinking behavior (alcoholism), as well as studies of the effects of alcohol on brain function, started a logarithmic growth phase after the repeal of the 18th Amendment to the United States Constitution. Although the early studies were primitive by current technological standards, they clearly demonstrated the effects of alcohol on brain structure and function, and by the end of the 20th century left little doubt that alcoholism is a "disease" of the brain. This review traces the history of developments in the understanding of ethanol's effects on the most prominent inhibitory and excitatory systems of brain (GABA and glutamate neurotransmission). This neurobiological information is integrated with knowledge of ethanol's actions on other neurotransmitter systems to produce an anatomical and functional map of ethanol's properties. Our intent is limited in scope, but is meant to provide context and integration of the actions of ethanol on the major neurobiologic systems which produce reinforcement for alcohol consumption and changes in brain chemistry that lead to addiction. The developmental history of neurobehavioral theories of the transition from alcohol drinking to alcohol addiction is presented and juxtaposed to the neurobiological findings. Depending on one's point of view, we may, at this point in history, know more, or less, than we think we know about the neurobiology of alcoholism.

Re-analysis employing covariance-structural models was conducted on Strickland's (1983) survey data on 772 drinking students from Grades 7, 9 and 11. These data bear on the relations among alcohol consumption, alcohol abuse, association with drinking peers and exposure to televised alcohol advertising. Whereas Strickland used a just-identified model which, therefore, could not be tested for goodness of fit, our re-analysis tested several alternative models, which could be contradicted by the data. One model did fit his data particularly well. Its major implications are as follows: (1) Symptomatic consumption, negative consequences and self-rated severity of alcohol-related problems apparently reflect a common underlying factor, namely alcohol abuse. (2) Use of alcohol to relieve distress and frequency of intoxication, however, appear not to reflect abuse, although frequent intoxication contributes substantially to it. (3). Alcohol advertising affects consumption directly and abuse indirectly, although peer association has far greater impact on both consumption and abuse. These findings are interpreted as lending little support to further restrictions on advertising.

Background We conducted a population-based case–control study to better delineate the relationship between individual alcohol consumption, alcohol outlets in the surrounding environment, and being assaulted with a gun. Methods An incidence density sampled case–control study was conducted in the entire city of Philadelphia from 2003 to 2006. We enrolled 677 cases that had been shot in an assault and 684 population-based controls. The relationships between 2 independent variables of interest, alcohol consumption and alcohol outlet availability, and the outcome of being assaulted with a gun were analyzed. Conditional logistic regression was used to adjust for numerous confounding variables. Results After adjustment, heavy drinkers were 2.67 times as likely to be shot in an assault when compared with nondrinkers (p < 0.10) while light drinkers were not at significantly greater risk of being shot in an assault when compared with nondrinkers. Regression-adjusted analyses also demonstrated that being in an area of high off-premise alcohol outlet availability significantly increased the risk of being shot in an assault by 2.00 times (p < 0.05). Being in an area of high on-premise alcohol outlet availability did not significantly change this risk. Heavy drinkers in areas of high off-premise alcohol outlet availability were 9.34 times (p < 0.05) as likely to be shot in an assault. Conclusions This study finds that the gun assault risk to individuals who are near off-premise alcohol outlets is about the same as or statistically greater than the risk they incur from heavy drinking. The combination of heavy drinking and being near off-premise outlets resulted in greater risk than either factor alone. By comparison, light drinking and being near on-premise alcohol outlets were not associated with increased risks for gun assault. Cities should consider addressing alcohol-related factors, especially off-premise outlets, as highly modifiable and politically feasible approaches

Epidemiological and experimental studies have consistently linked alcoholic beverage consumption with the development of several chronic disorders, such as cancer, cardiovascular diseases, diabetes mellitus and obesity. The impact of drinking is usually dose-dependent, and light to moderate drinking tends to lower risks of certain diseases, while heavy drinking tends to increase the risks. Besides, other factors such as drinking frequency, genetic susceptibility, smoking, diet, and hormone status can modify the association. The amount of ethanol in alcoholic beverages is the determining factor in most cases, and beverage types could also make an influence. This review summarizes recent studies on alcoholic beverage consumption and several chronic diseases, trying to assess the effects of different drinking patterns, beverage types, interaction with other risk factors, and provide mechanistic explanations.

Excessive alcohol consumption represents a significant concern on U.S. college campuses and there is a need to identify students who may be at risk for engaging in risky alcohol use. The current study examined how variables measured prior to college matriculation, specifically alcohol-related decision-making variables drawn from the Theory of Reasoned Action (i.e., alcohol expectancies, attitudes, and normative beliefs), were associated with patterns of alcohol use prior to and throughout the first semesters of college. Participants were 392 undergraduate students (56% female) from a large Northeastern U.S. university. Decision-making variables were assessed prior to college matriculation and alcohol use was measured with 5 assessments before and throughout freshman and sophomore semesters. Latent profile analysis was used to identify types of students with distinct patterns of decision-making variables. These decision-making profiles were subsequently linked to distinct patterns of alcohol use using latent transition analysis. Four distinct decision-making profiles were found and were labeled “Anti-Drinking”, “Unfavorable”, “Mixed”, and “Risky”. Five drinking patterns were observed and included participants who reported consistently low, moderate, or high rates of alcohol use. Two patterns described low or non-drinking at the pre-college baseline with drinking escalation during the measurement period. Students' likelihood of following the various drinking patterns varied according to their decision-making. Findings suggest the early identification of at-risk students may be improved by assessing decision-making variables in addition to alcohol use. The findings also have implications for the design of early identification assessments to identify at-risk college students and for the targeting of alcohol prevention efforts to students based on their alcohol-related attitudes and beliefs.

Objective Recent studies suggest drinking protective behaviors (DPBs) and contextual protective behaviors (CPBs) can uniquely reduce alcohol-related sexual risk in college students. Few studies have examined CPBs independently, and even fewer have utilized theory to examine modifiable psychosocial predictors of students’ decisions to use CPBs. The current study used a prospective design to examine 1) rational and reactive pathways and psychosocial constructs predictive of CPB use, and 2) how gender might moderate these influences in a sample of college students. Method Students (n = 508) completed web-based baseline (mid-spring semester) and 1- and 6-month follow-up assessments of CPB use; psychosocial constructs (expectancies, normative beliefs, attitudes, and self-concept); and rational and reactive pathways (intentions and willingness). Regression was used to examine rational and reactive influences as proximal predictors of CPB use at the 6-month follow-up. Subsequent path analyses examined the effects of psychosocial constructs, as distal predictors of CPB use, mediated through the rational and reactive pathways. Results Both rational (intentions to use CPB) and reactive (willingness to use CPB) influences were significantly associated with increased CPB use. The examined distal predictors were found to effect CPB use differentially through the rational and reactive pathways. Gender did not significantly moderate any relationships within in the model. Discussion Findings suggest potential entry points for increasing CPB use that include both rational and reactive pathways. Overall, this study demonstrates the mechanisms underlying how to increase the use of CPBs in programs designed to reduce alcohol-related sexual consequences and victimization. PMID:26415062

Introduction Excessive alcohol consumption increases the risk of many diseases and injuries, and the Global Burden of Disease 2010 study estimated that 6% of the burden of disease in Denmark is due to alcohol consumption. Alcohol consumption thus places a considerable economic burden on society. Methods We analysed the cost-effectiveness of six interventions aimed at preventing alcohol abuse in the adult Danish population: 30% increased taxation, increased minimum legal drinking age, advertisement bans, limited hours of retail sales, and brief and longer individual interventions. Potential health effects were evaluated as changes in incidence, prevalence and mortality of alcohol-related diseases and injuries. Net costs were calculated as the sum of intervention costs and cost offsets related to treatment of alcohol-related outcomes, based on health care costs from Danish national registers. Cost-effectiveness was evaluated by calculating incremental cost-effectiveness ratios (ICERs) for each intervention. We also created an intervention pathway to determine the optimal sequence of interventions and their combined effects. Results Three of the analysed interventions (advertising bans, limited hours of retail sales and taxation) were cost-saving, and the remaining three interventions were all cost-effective. Net costs varied from € -17 million per year for advertisement ban to € 8 million for longer individual intervention. Effectiveness varied from 115 disability-adjusted life years (DALY) per year for minimum legal drinking age to 2,900 DALY for advertisement ban. The total annual effect if all interventions were implemented would be 7,300 DALY, with a net cost of € -30 million. Conclusion Our results show that interventions targeting the whole population were more effective than individual-focused interventions. A ban on alcohol advertising, limited hours of retail sale and increased taxation had the highest probability of being cost-saving and should thus

We investigated the question, how do older men who drink alcohol differ from those who do not drink on measures of cognitive function, memory, affect, and health? Of the nonprobability sample of male participants (N = 60), 35 (58%) of the males reported some degree of alcohol consumption. Eleven men had one or more drinks per day, 14 had one or more drinks per week, and 9 were occasional drinkers. The drinkers reported significantly less depression, had higher self-reported general health and vitality, and had higher cognitive performance, cognitive flexibility, and verbal memory, and greater knowledge of memory processes.

Alcohol consumption in France exceeds the European average (12.7L of pure alcohol/habitant/year in 2009 for an average of 12.5 L). This consumption has a major professional, social and health impact on the individuals and their families. The cost of such, estimated in Europe to be of 155.8 billion Euros in 2010, is the highest among the central nervous system diseases in Europe, far higher than that of depression or dementia. Patients suffering from psychiatric disorders are more frequently affected by problems related to alcohol use than the general population. They are also more vulnerable to the immediate and subsequent consequences of their consumption. The alcohol related disorders that are often accompanied by risk taking and other addictive behaviour require a global assessment of the addiction, with and without substance, and of the complications. These have a strong impact on risk taking, compliance with care, and the morbidity of somatic and psychiatric disorders, as well as access to optimal care and the life span of patients suffering from psychiatric disorders. The development of addictology care, with integrative treatment programs, is recommended in response to these public health issues. Nevertheless, specific addictology practices and partners with addictology care structures are still scarcely developed in psychiatry. Firstly, it would be necessary to set up such integrated treatments through the systematisation of an "addictology" checkup on admission, a global assessment of addictive behaviour and cognitive disorders, using pragmatic tools that are user-friendly for the care teams, maintain the reduction in risk taking, and apply prescriptions for addiction to psychotropic treatments, in liaison with the referring general practitioner. As early as possible, accompanied by specific training in addictology for the psychiatrists and the mental health nursing teams, such care could be enhanced by the development of liaison and advanced psychiatric

The association between alcohol intake and colorectal cancer (CRC) may vary secondary to single nucleotide polymorphisms (SNPs) in two pathways related to alcohol intake. 375 cases of CRC were identified among 38 373 Japan Public Health Center-based prospective Study (JPHC Study) participants who had returned a baseline questionnaire, reported no diagnosis of any cancer and provided blood samples. For each case, two controls were selected on matching variables. Logistic regression models were used to determine matched Odds Ratios (OR) and 95% Confidence Intervals (CI) for the association between alcohol consumption, genetic polymorphisms of enzymes in the alcohol- and folate metabolic pathways (e.g. methylenetetrahydrofolate reductase (MTHFR) rs1801133) and CRC risk. Compared to never/occasional alcohol intake, moderate to heavy alcohol intake was associated with CRC (OR = 2.12, 95% CI, 1.34–3.36). When compared to the CC genotype, the MTHFR rs1801133 CT/TT genotype was inversely associated with CRC (OR = 0.72, 95% CI, 0.54–0.97). Never/occasional consumers of alcohol with the MTHFR rs1801133 CT/TT genotype were also at a reduced risk of CRC compared to never/occasional drinkers with the CC genotype (OR = 0.68, 95% CI, 0.47–0.98) (P for interaction = 0.27). The results indicate that the folate pathway is likely to be involved in alcohol-related CRC development. PMID:27827401

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.

Consumption of alcohol was investigated in two groups of pregnant women: an intervention group (n = 58) (two structured interviews during pregnancy including counseling focused on reduction of alcohol consumption and potential benefits to the fetus, and interview after delivery), and a control group (n = 74) (interview after delivery). Prepregnancy 80% of the women were light or moderate alcohol consumers, and 20% teetotalers. Pregnancy considerably reduced alcohol consumption in both groups. 66% abstained from alcohol during pregnancy, and use of liquor nearly ceased. The changes in alcohol consumption occurred independently to the intervention program. Strategy for reducing alcohol consumption during pregnancy should include a structured alcohol anamnesis at the first ante-natal visit, accompanied by counseling focused on reduction of alcohol consumption. More extensive intervention programs may be reserved for pregnancies at higher risk (high-consumers, abusers).

Discrepancies between parents and adolescents regarding parenting behaviors have been hypothesized to represent a deficit in the parent-child relationship and may represent unique risk factors for poor developmental outcomes. The current study examined the predictive utility of multiple methods for characterizing discrepancies in parents’ and adolescents’ reports of parental monitoring on youth alcohol use behaviors in order to inform future study design and predictive modeling. Data for the current study came from a prospective investigation of alcohol initiation and progression. The analyzed sample consisted of 606 adolescents (6th – 8th grade; 54% female) and their parents were surveyed at baseline, with youth followed up 12 months later. A series of hierarchical logistic regressions were performed for each monitoring-related construct examined (parental knowledge, parental control, parental solicitation, and child disclosure). The results showed that adolescents’ reports were more closely related to outcomes than parents’ reports, while greater discrepancies were frequently found to be uniquely associated with greater likelihood of alcohol use behaviors. Implications for future work incorporating parents’ and adolescents’ reports are discussed. PMID:24964878

The zebrafish is becoming increasingly popular in behavior genetics because it may allow one to conduct large scale mutation and drug screens facilitating the discovery of mechanisms of complex traits. Strain differences in adult zebrafish behavior have already been reported, which may have important implications in neurobehavioral genetics. For example, we have found the AB and SF strains to differ in their behavioral responses to both acute and chronic alcohol exposure. In the current study, we further characterize these strains using semi-quantitative RT-PCR to measure the expression of ten selected genes and HPLC to measure the levels of nine neurochemicals. We chose the target genes and neurochemicals based upon their potential involvement in alcohol and other drugs of abuse related mechanisms. We quantified the expression of the genes encoding D1-R, D2a-R, D4a-R dopamine receptors, GABA(A)-R, GABA(B)-R1, GAD1, MAO, NMDA-R (NR2D subunit), 5HT-R1bd and SLC6 a4a. We found the gene encoding D1 dopamine receptor over-expressed and the genes encoding GABA(B1) receptor and solute family carrier protein 6 (SLC6) 4a under-expressed in SF compared to AB. We also found the level of all (dopamine, DOPAC, Serotonin, GABA, Glutamate, Glycine, Aspartate, Taurine) but one (5HIAA) neurochemicals tested decreased in SF as compared to AB. These results, combined with previously identified behavioral differences between the AB and SF strains, demonstrate the importance of strain characterization in zebrafish. They now also allow formulation of working hypotheses about possible mechanisms underlying the differential effects of acute and chronic alcohol treatment on these two zebrafish strains.

Trait positive urgency is characterised by risky and maladaptive actions in response to extreme positive affective states. Positive urgency has previously been shown to be a risk factor for alcohol consumption and alcohol-related problems; however, there has been limited experimental research examining how positive urgency may moderate relations between affective states and alcohol consumption. In the current study, a sample of 106 participants completed a trait measure of positive urgency and were then randomly assigned to one of three mood induction conditions: a high-activation positive, a low-activation positive or a neutral mood condition. Subsequently, participants took part in a bogus beer taste test, where their alcohol consumption was subsequently measured. The results revealed that positive urgency significantly predicted increased beer consumption, but only for those participants in the high-activation positive mood induction group. The findings from this study provide support for positive urgency as a risk factor for alcohol use and suggest that it may be of particular relevance in social situations where individuals experience highly activated positive affective states.
This study utilizes a balanced panel data set covering 50 monthly observations regarding the brewery products to examine the impact of holy month Ramadan on alcohol consumption in Turkey. In addition to the Ramadan, temperature, prices of the products and disposable income are other demand factors which are taken into account in this study. As expected, the Ramadan has been found to be associated with lower alcohol usage. As price of alcoholic drinks increases, the alcohol consumption decreases significantly. In addition, alcohol consumption rises with the enhancements in the disposable income. However, surprisingly, the temperature has not any significant effect on alcohol consumption in Turkey.

To understand the impact of drinking and driving laws on drinking and driving fatality rates, this study explored the different effects these laws have on areas with varying severity rates for drinking and driving. Unlike previous studies, this study employed quantile regression analysis. Empirical results showed that policies based on local conditions must be used to effectively reduce drinking and driving fatality rates; that is, different measures should be adopted to target the specific conditions in various regions. For areas with low fatality rates (low quantiles), people’s habits and attitudes toward alcohol should be emphasized instead of transportation safety laws because “preemptive regulations” are more effective. For areas with high fatality rates (or high quantiles), “ex-post regulations” are more effective, and impact these areas approximately 0.01% to 0.05% more than they do areas with low fatality rates.

Background Alcoholic beverages are widely consumed. Depression, the most prevalent mental disorder worldwide, has been related to alcohol intake. We aimed to prospectively assess the association between alcohol intake and incident depression using repeated measurements of alcohol intake. Methods We followed-up 5,505 high-risk men and women (55 to 80 y) of the PREDIMED Trial for up to seven years. Participants were initially free of depression or a history of depression, and did not have any history of alcohol-related problems. A 137-item validated food frequency questionnaire administered by a dietician was repeated annually to assess alcohol intake. Participants were classified as incident cases of depression when they reported a new clinical diagnosis of depression, and/or initiated the use of antidepressant drugs. Cox regression analyses were fitted over 23,655 person-years. Results Moderate alcohol intake within the range of 5 to 15 g/day was significantly associated with lower risk of incident depression (hazard ratio (HR) and 95% confidence interval (95% CI) = 0.72 (0.53 to 0.98) versus abstainers). Specifically, wine consumption in the range of two to seven drinks/week was significantly associated with lower rates of depression (HR (95% CI) = 0.68 (0.47 to 0.98)). Conclusions Moderate consumption of wine may reduce the incidence of depression, while heavy drinkers seem to be at higher risk. PMID:23988010

Introduction Alcohol use among young people is a major public health concern in Australia and internationally. Research elucidating social norms influencing alcohol use supports the desire to conform to peers. However, there is a lack of evidence on how social norms are transmitted from the community to young people and between family members and peers, as previous studies are limited to mainly school and university environments. This article describes the proposed process to investigate common alcohol-related norms held by 14-year-olds to 17-year-olds in Perth, Western Australia, and to clarify the process and pathways through which proalcohol norms are transmitted to adolescents. Methods and analysis This cross-sectional quantitative study will use respondent-driven sampling (RDS) to recruit a sample of 672 adolescents from sporting groups, youth programmes and the community in Perth. Data will be collected with a previously developed and validated multidimensional online survey instrument. A variety of strategies will be explored to aid participation including face-to-face recruitment and survey administration, web-based RDS and a ‘mature minor’ consent assessment protocol. Data analysis will include descriptive statistics of demographic characteristics, as well as social network and dyadic analyses, to explore the connections between shared understanding of norms and behaviours among individuals and how these translate into reported practices. Ethics and dissemination This research is expected to extend our understanding of normative development pathways to inform future interventions, and will be widely disseminated through conference presentations, peer-reviewed papers, media channels and community seminars. A study reference group of key health industry stakeholders will be established to encourage integration of study findings into policy and practice, and results will guide the development of community interventions.

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.

Heavy maternal alcohol consumption during early pregnancy increases the risk of oral clefts, but little is known about how genetic variation in alcohol metabolism affects this association. Variants in the alcohol dehydrogenase 1C (ADH1C) gene may modify the association between alcohol and clefts. In a population-based case-control study carried out in Norway (1996–2001), the authors examined the association between maternal alcohol consumption and risk of oral clefts according to mother and infant ADH1C haplotypes encoding fast or slow alcohol-metabolizing phenotypes. Subjects were 483 infants with oral cleft malformations and 503 control infants and their mothers, randomly selected from all other livebirths taking place during the same period. Mothers who consumed 5 or more alcoholic drinks per sitting during the first trimester of pregnancy had an elevated risk of oral cleft in their offspring (odds ratio (OR) = 2.6, 95% confidence interval (CI): 1.4, 4.7). This increased risk was evident only in mothers or children who carried the ADH1C haplotype associated with reduced alcohol metabolism (OR= 3.0, 95% CI: 1.4, 6.8). There was no evidence of alcohol-related risk when both mother and infant carried only the rapid-metabolism ADH1C variant (OR = 0.9, 95% CI: 0.2, 4.1). The teratogenic effect of alcohol may depend on the genetic capacity of the mother and fetus to metabolize alcohol. PMID:20810466

Public acceptability influences policy action, but the most acceptable policies are not always the most effective. This discrete choice experiment provides a novel investigation of the acceptability of different interventions to reduce alcohol consumption and the effect of information on expected effectiveness, using a UK general population sample of 1202 adults. Policy options included high, medium and low intensity versions of: Minimum Unit Pricing (MUP) for alcohol; reducing numbers of alcohol retail outlets; and regulating alcohol advertising. Outcomes of interventions were predicted for: alcohol-related crimes; alcohol-related hospital admissions; and heavy drinkers. First, the models obtained were used to predict preferences if expected outcomes of interventions were not taken into account. In such models around half of participants or more were predicted to prefer the status quo over implementing outlet reductions or higher intensity MUP. Second, preferences were predicted when information on expected outcomes was considered, with most participants now choosing any given intervention over the status quo. Acceptability of MUP interventions increased by the greatest extent: from 43% to 63% preferring MUP of £1 to the status quo. Respondents' own drinking behaviour also influenced preferences, with around 90% of non-drinkers being predicted to choose all interventions over the status quo, and with more moderate than heavy drinkers favouring a given policy over the status quo. Importantly, the study findings suggest public acceptability of alcohol interventions is dependent on both the nature of the policy and its expected effectiveness. Policy-makers struggling to mobilise support for hitherto unpopular but promising policies should consider giving greater prominence to their expected outcomes.

Understanding of the relation between the alcoholic consumption and the development of pancreatitis should help in defining the alcoholic etiology of pancreatitis. Although the association between alcohol consumption and pancreatitis has been recognized for over 100 years, it remains still unclear why some alcoholics develop pancreatitis and some do not. Surprisingly little data are available about alcohol amounts, drinking patterns, type of alcohol consumed and other habits such as dietary habits or smoking in respect to pancreatitis preceding the attack of acute pancreatitis or the time of the diagnosis of chronic pancreatitis. This review summarizes the current knowledge. Epidemiological studies clearly show connection between the alcohol consumption in population and the development of acute and chronic pancreatitis. In the individual level the risk to develop either acute or chronic pancreatitis increases along with the alcohol consumption. Moreover, the risk for recurrent acute pancreatitis after the first acute pancreatitis episode seems also to be highly dependent on the level of alcohol consumption. Abstaining from alcohol may prohibit recurrent acute pancreatitis and reduce pain in chronic pancreatitis. Therefore, all the attempts to decrease alcohol consumption after acute pancreatitis and even after the diagnosis of chronic pancreatitis should be encouraged. Smoking seems to be a remarkable co-factor together with alcohol in the development of chronic pancreatitis, whereas no hard data are available for this association in acute pancreatitis. Setting the limits for accepting the alcohol as the etiology cannot currently be based on published data, but rather on the 'political' agreement.
Aim Concerns have been raised about the impact of alcohol sports sponsorship on harmful consumption, with some countries banning this practice or considering a ban. We review evidence on the relationship between exposure to alcohol sports sponsorship and alcohol consumption. Methods Search of electronic databases (PubMed, Cochrane Library, Google Scholar and International Alcohol Information Database) supplemented by hand searches of references and conference proceedings to locate studies providing data on the impact of exposure to alcohol sports sponsorship and outcomes relating to alcohol consumption. Results Seven studies met inclusion criteria, presenting data on 12,760 participants from Australia, New Zealand, the UK, Germany, Italy, Netherlands and Poland. All studies report positive associations between exposure to alcohol sports sponsorship and self-reported alcohol consumption, but the statistical significance of results varies. Two studies found indirect exposure to alcohol sports sponsorship was associated with increased levels of drinking amongst schoolchildren, and five studies found a positive association between direct alcohol sports sponsorship and hazardous drinking amongst adult sportspeople. Conclusion These findings corroborate the results of previous systematic reviews that reported a positive association between exposure to alcohol marketing and alcohol consumption. The relationship between alcohol sports sponsorship and increased drinking amongst schoolchildren will concern policymakers. Further research into the effectiveness of restrictions on alcohol sports sponsorship in reducing harmful drinking is required. PMID:26911984

Background The purpose of this study was to examine whether facial flushing after drinking influences the relationship between alcohol consumption and prostatic hyperplasia among Korean men. Methods The subjects were 957 Korean men (180 non-drinkers, 389 with drinking-related facial flushing, 388 without facial flushing) in the 40–69 age group, who underwent prostate ultrasound at the health promotion center of Chungnam National University Hospital between 2008 and 2014. Alcohol consumption and alcohol-related facial flushing were assessed through a questionnaire. In terms of the amount consumed, 14 g of alcohol was considered a standard drink. With the non-drinker group as reference, logistic regression was used to analyze the relationship between weekly alcohol intake and prostatic hyperplasia in the flushing and non-flushing groups, with adjustment for confounding factors such as age, body mass index, smoking, and exercise patterns. Results Individuals aged 50–59 years who experienced drinking-related facial flushing had a significantly lower risk of prostatic hyperplasia than the non-drinker group, depending on alcohol consumption: ≤4 standard drinks (adjusted odds ratio [OR], 0.38; 95% confidence interval [CI], 0.16 to 0.86); >4 ≤8 standard drinks (OR, 0.35; 95% CI, 0.13 to 0.95); >8 standard drinks (OR, 0.33; 95% CI, 0.13 to 0.84). However, no significant relationship was observed between the number of drinks consumed and the risk of prostate hyperplasia in the non-flushing group. Conclusion The risk of prostatic hyperplasia appears to be reduced by alcohol consumption among Korean men aged 50–59 years who exhibit drinking-related facial flushing. PMID:28360985

The prevalence of alcohol consumption, the choice of beverages and the quantity of drinks used by a Polynesian society are described, both in the Tokelau atolls and among Tokelauan migrants in New Zealand. Current drinking was uncommon but increasing among women. Among men, it was more common, but both prevalence and quantity were modest compared with national alcohol consumption in New Zealand. Description of alcohol consumption in such migrant populations may provide a basis for encouraging continuing prudence regarding alcohol and ready acceptance and provision for the non-drinker of alcohol.

A postal survey of New Zealand general practitioners gathered information from a self-selected sample about their response to alcohol problems. Responses to a series of attitude statements measured the extent to which doctors held traditional beliefs about alcoholism as a disease, the management of which requires abstinence; emerging concepts of alcohol dependence and more moralistic attitudes. General practitioners who responded to the survey were found to be largely in sympathy with the disease concept of alcohol problems though some of the more recently emerging concepts were also widely accepted. The majority reported that they felt they did have an active role to play in connection with the alcohol problems of their patients, both in terms of treatment or advice giving, and referral to specialist agencies. Over half of the respondents requested guidelines for treatment and advice giving. Only a small proportion of general practitioners reported pessimism about their personal role in relation to their patients' alcohol problems. The results are discussed in the context of recent research evidence showing the relative efficacy of a structured advice-counseling session of the type in which general practitioners might engage.

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.

Objective To examine drinking patterns and alcohol-related problems among youth in Jujuy, Argentina. Material and Methods A survey was conducted in 2005 with a representative sample of 9th grade youth (12 to 17 years old) including sociodemographic and consumption data, and the AUDIT-C test. Results Nine percent of girls and 11% of boys reported hazardous drinking; 12% of girls and 19% of boys reported dependence symptoms. The odds ratio for dependence symptoms (adjusted OR 0.7; 95%CI: 0.6-0.8) and for hazardous drinking (adjusted OR 0.7; 95%CI: 0.6-0.8) was significantly lower for girls compared with boys. Older age, working, and attending night school were risk factors for hazardous drinking, dependence symptoms, and harmful drinking. Conclusions A significant proportion of youth reported problematic patterns of alcohol drinking, highlighting the need to implement prevention and treatment interventions tailored to the adolescent population.

This study investigated the impact of mild-moderate dehydration on alcohol-induced deteriorations in cognitive functions. Sixteen healthy males participated in a single-blind, placebo-controlled cross-over design study involving 4 experimental trials (separated by ≥7 d). In each trial, participants were dehydrated by 2.5% body mass through exercise. After 1 h recovery in a thermo-neutral environment (22 ± 2 °C, 60-70% relative humidity) 4 tasks from the Cambridge Neuropsychological Test Automated Battery (CANTAB) were administered to the participants (test 1). In two of the trials, participants were provided with water equivalent to either 50% or 150% body mass loss and given salt (NaCl) capsules (50 mmol/L). A set volume of alcohol or placebo was then consumed in each trial, incorporating the conditions: dehydration-placebo (DP), dehydration-alcohol (DA), partial rehydration-alcohol (PA), and full rehydration-alcohol (FA). The same 4 CANTAB tasks were then re-administered (test 2). Subjective ratings of mood and estimates of alcohol intoxication and driving impairment were also recorded in each trial. Alcohol consumption caused deterioration on 3 of the 4 CANTAB measures (viz., choice reaction time, executive function and response inhibition). This reduction in performance was exacerbated when participants were dehydrated compared to trials where full rehydration occurred. Subjective ratings of impairment and intoxication were not significantly different between any of the trials where alcohol was consumed; however ratings for alcohol trials were significantly higher than in the placebo trial. These findings suggest that rehydration after exercise that causes fluid loss can attenuate alcohol-related deterioration of cognitive functions. This may pose implications for post match fluid replacement if a moderate amount of alcohol is also consumed.

The present paper aims to review current evidence for the effectiveness and/or feasibility of using inter-agency data sharing of ED recorded assault information to direct interventions reducing alcohol-related or nightlife assaults, injury or violence. Potential data-sharing partners involve police, local council, liquor licensing regulators and venue management. A systematic review of the peer-reviewed literature was conducted. The initial search discovered 19,506 articles. After removal of duplicates and articles not meeting review criteria, n = 8 articles were included in quantitative and narrative synthesis. Seven of eight studies were conducted in UK EDs, with the remaining study presenting Australian data. All studies included in the review deemed data sharing a worthwhile pursuit. All studies attempting to measure intervention effectiveness reported substantial reductions of assaults and ED attendances post-intervention, with one reporting no change. Negative logistic feasibility concerns were minimal, with general consensus among authors being that data-sharing protocols and partnerships could be easily implemented into modern ED triage systems, with minimal cost, staff workload burden, impact to patient safety, service and anonymity, or risk of harm displacement to other licensed venues, or increase to length of patient stay. However, one study reported a potential harm displacement effect to streets surrounding intervention venues. In future, data-sharing systems should triangulate ED, police and ambulance data sources, and assess intervention effectiveness using randomised controlled trials that account for variations in venue capacity, fluctuations in ED attendance and population levels, seasonal variations in assault and injury, and control for concurrent interventions.

AIMS As part of a larger study to estimate the global burden of disease and injury attributable to alcohol: To evaluate the evidence for a causal impact of average volume of alcohol consumption and pattern of drinking on diseases and injuries;To quantify relationships identified as causal based on published meta-analyses;To separate the impact on mortality vs. morbidity where possible; andTo assess the impact of the quality of alcohol on burden of disease. METHODS Systematic literature reviews were used to identify alcohol-related diseases, birth complications and injuries using standard epidemiologic criteria to determine causality. The extent of the risk relations was taken from meta-analyses. RESULTS Evidence of a causal impact of average volume of alcohol consumption was found for the following major diseases: tuberculosis, mouth, nasopharynx, other pharynx and oropharynx cancer, oesophageal cancer, colon and rectum cancer, liver cancer, female breast cancer, diabetes mellitus, alcohol use disorders, unipolar depressive disorders, epilepsy, hypertensive heart disease, ischaemic heart disease (IHD), ischaemic and haemorrhagic stroke, conduction disorders and other dysrhythmias, lower respiratory infections (pneumonia), cirrhosis of the liver, preterm birth complications, foetal alcohol syndrome. Dose-response relationships could be quantified for all disease categories except for depressive disorders, with the relative risk increasing with increased level of alcohol consumption for most diseases. Both average volume and drinking pattern were causally linked to IHD, foetal alcohol syndrome, and unintentional and intentional injuries. For IHD, ischaemic stroke and diabetes mellitus beneficial effects were observed for patterns of light to moderate drinking without heavy drinking occasions (as defined by 60+ grams pure alcohol per day). For several disease and injury categories, the effects were stronger on mortality compared to morbidity. There was insufficient

Aims To investigate the relationship between legalization of Sunday alcohol sales and alcohol consumption in the United States. Design State-level per capita consumption of beer, wine, and spirits was analyzed using difference-in-differences econometric methods. Setting United States. Participants 5 treatment states that repealed their laws restricting Sunday alcohol sales during 1990–2007 and 12 control states that retained their Sunday alcohol laws during the same period. Measurements Outcome measures are state-level per capita consumption of overall alcohol, beer, wine, and spirits. Findings Among the states that legalized Sunday sales of alcoholic beverages, Delaware, Pennsylvania, and New Mexico experienced significant increases in overall alcohol consumption (P<0.05). However, the effect of the legalization of Sunday alcohol sales in Massachusetts and Rhode Island on per capita alcohol consumption was insignificant (P=0.964 and P=0.367). Conclusions Three out of five states in the USA that repealed their laws restricting Sunday sale of alcoholic beverages during 1990–2007, experienced significant increases in per capita alcohol consumption. This finding implies that increased alcohol availability leads to an increase in alcohol consumption. PMID:24103041

Closed circuit television (CCTV) systems which incorporate real-time communication links between camera room operators and on-the-ground security may limit injuries resulting from alcohol-related assault. This pilot study examined CCTV footage and operator records of security responses for two periods totalling 22 days in 2010-2011 when 30 alcohol-related assaults were recorded. Semistructured discussions were conducted with camera room operators during 18 h of observation. Camera operators were proactive, efficiently directing street security to assault incidents. The system intervened in 40% (n=12) of alcohol-related assaults, limiting possible injury. This included three incidents judged as potentially preventable. A further five (17%) assault incidents were also judged as potentially preventable, while 43% (n=13) happened too quickly for intervention. Case studies describe security intervention in each category. Further research is recommended, particularly to evaluate the effects on preventing injuries through targeted awareness training to improve responsiveness and enhance the preventative capacity of similar CCTV systems.

OBJECTIVES: the aim of this study was to analyze alcohol consumption by university students and psychosocial problems related. METHOD: descriptive correlational study that included 396 university students. The "Alcohol Use Disorders Identification Test" - (AUDIT) - and an "ad hoc" questionnaire were used as instruments to assess the associated problems. RESULTS: of the total sample, 88.6% drank, 20.5% had harmful consumption and 14.9% were at risk of dependence according to AUDIT. The study showed important results related to harmful alcohol consumption and dependence, with damage to the academic performance, social relationships, psychological status and sexual condition. CONCLUSIONS: complications caused by problematic alcohol consumption by university students, which is high in this group due to the high prevalence of their alcohol consumption, highlights the importance of promoting programs to prevent the abuse and dependence of this substance in universities.

The objective of this study was to identify differences in high school students' attitudes towards the consumption or non-consumption of alcohol using the theory of planned behavior. This was a qualitative, descriptive, cross-sectional study that included a sample of 131 students. We found that 74% of students had consumed alcohol, and 18.3% exhibited a harmful level of consumption. We also found that behavioral beliefs towards consumption were higher among alcohol consumers (mean=29.32, median=27.50) than those who did not consume alcohol. Moreover, positive beliefs towards consumption were higher among alcohol consumers (mean=17.72, median=9.52) than non-consumers, which demonstrates a need for preventative programs to strengthen adolescents' beliefs concerning alcohol as well as protective factors and healthy lifestyles.
Background Despite intense investigation, the temporal sequence between alcohol consumption and mental health remains unclear. This study explored the relationship between alcohol consumption and mental health over multiple occasions, and compared a series of competing theoretical models to determine which best reflected the association between the two. Methods Data from phases 5 (1997 to 1999), 7 (2002 to 2004), and 9 (2007 to 2009) of the Whitehall II prospective cohort study were used, providing approximately 10 years of follow-up for 6,330 participants (73% men; mean ± SD age 55.8 ± 6.0 years). Mental health was assessed using the Short Form (SF)-36 mental health component score. Alcohol consumption was defined as the number of UK units of alcohol drunk per week. Four dynamic latent change score models were compared: 1) a baseline model in which alcohol consumption and mental health trajectories did not influence each other, 2) and model in which alcohol consumption influenced changes in mental health but mental health exerted no effect on changes in drinking and 3) vice versa, and (4) a reciprocal model in which both variables influenced changes in each other. Results The third model, in which mental health influenced changes in alcohol consumption but not vice versa, was the best fit. In this model, the effect of previous mental health on upcoming change in alcohol consumption was negative (γ = -0.31, 95% CI -0.52 to -0.10), meaning that those with better mental health tended to make greater reductions (or shallower increases) in their drinking between occasions. Conclusions Mental health appears to be the leading indicator of change in the dynamic longitudinal relationship between mental health and weekly alcohol consumption in this sample of middle-aged adults. In addition to fuelling increases in alcohol consumption among low-level consumers, poor mental health may also be a maintaining factor for heavy alcohol consumption. Future work

There is a considerable degree of individual vulnerability for alcohol use disorder (AUD) as only a subpopulation of individuals who regularly consume alcohol develop AUD. It is therefore very important to understand the factors and mechanisms that contribute towards the individual risk for AUD. In this respect, social influences, in particular during development, may be relevant for AUD as disruptions in early social experiences are associated with an increased risk for AUD. Social play, the most prominent form of social behaviour shown by young mammals, is rewarding and considered to be important for social, emotional and cognitive development. Recent studies suggest that early social isolation, effectively depriving animals from social play, increases the risk for addictive behaviour. The aim of this study was therefore to explore the long-term consequences of early social isolation on alcohol consumption and motivation for alcohol. To this end, rats were socially isolated from postnatal days 21-42, followed by 4 weeks of social housing, and voluntary alcohol consumption and operant responding for alcohol were determined in adulthood. We observed enhanced levels of alcohol consumption in adulthood in previously isolated rats, whereas operant responding for alcohol was not altered. The impact of early social isolation was independent of the individual variation in alcohol consumption. These data indicate that social isolation, during a developmental period when social play is highly abundant, enhances the propensity to consume alcohol in adulthood. This implies that early social experience may be a protective factor against excessive alcohol use.

Objective To examine emergency department (ED) data sharing via a local injury surveillance system and assess its contribution to the prevention of violence and alcohol-related harms. Methods 6-year (2004–2010) exploratory study analysing injury attendances to one ED in the North West of England using descriptive and trend analyses. Results Over the 6-year period, there were 242 796 ED injury attendances, including 21 683 for intentional injuries. Compared with unintentional injury patients, intentional injury patients were more likely to be men, aged 18–34 years, live in the most deprived communities, have attended the ED at night/weekends, have been injured in a public place and have consumed alcohol prior to the injury. Detailed data collected on alcohol and violence-related ED attendances were shared with local partners to monitor local trends and inform prevention activity including targeted policing and licensing enforcement. Over the 6-year period, intentional ED injury attendances decreased by 35.6% and alcohol-related assault attendances decreased by 30.3%. Conclusions The collection of additional ED data on assault details and alcohol use prior to injury, and its integration into multi-agency policy and practice, played an important role in driving local violence prevention activity. Further research is needed to assess the direct contribution ED data sharing makes to reductions in violence. PMID:22210640

Prior studies aimed at explaining cognitive-motivational reasons for drinking have focused on either cognitive or motivational factors, but not on both. This study examined the ability of both alcohol-attentional bias and motivational structure to predict alcohol consumption. Participants were university students (N=87) who completed a battery of tests, including the Personal Concerns Inventory (a measure of adaptive and maladaptive motivation), an alcohol Stroop test (a measure of alcohol-attentional bias), and an alcohol-use inventory. Regression, moderation, and mediation analyses showed that (a) maladaptive motivation and alcohol-attentional bias were positive predictors of alcohol consumption after participants' age, gender, and executive cognitive functioning had been controlled, and (b) maladaptive motivation and alcohol-attentional bias independently predicted alcohol consumption. The implications of the results for both theory and practice are discussed.

Possible selves, cognitions about the self that reflect hopes, fears, and expectations for the future, are reliable predictors of health risk behaviors but have not been explored as predictors of adolescents’ alcohol use. In a secondary analysis of data from 137 adolescents, we examined the influence of possible selves assessed in eighth grade on alcohol consumption (yes/no and level of use) in ninth grade. Having a most important feared possible self related to academics in eighth grade predicted alcohol abstinence in ninth grade. Among those who reported alcohol use, having many hoped-for possible selves and a most important hoped-for possible self related to academics in eighth grade predicted lower level of alcohol consumption in ninth grade. Interventions that foster the personal relevance and importance of academics and lead to the development of hoped-for possible selves may reduce adolescents’ alcohol consumption. PMID:25545451
Significant investment in advertising has been made to promote the consumption of alcoholic beverages, but only 0.5% of the GDP is allocated for preventing alcohol use. Although available evidence clearly demonstrates a causal relationship between ethanol and cancer, the perception of risk in the general population remains extremely low. This is partly due to the fact that alcohol consumption is considered as a "normal" habit in our society, mostly as a consequence of the lack of appropriate information. It should also be emphasized the lack of a common language within the healthcare community, in that too often alcohol is identified as a food or a preservative. The fourth edition of the RDA represents a true cultural revolution as it identifies alcohol consumption as a risk, regardless of the amount consumed. Recommended dosages are defined as low-risk dosages. It would be appropriate to correctly apply the Law 125/2001, which provides for inclusion of alcoholism in university education programs.

Past research on alcohol consumption patterns comparing Chinese and Caucasians indicates that significant group differences exist. Chinese, as a group, consume significantly less alcohol than their Caucasian counterparts. Explanations for these differences have been controversial. Some argue that it is due to cultural differences, whereas others contend that it is because of physiological differences. The present study explores this controversy using a new approach: model testing via path analysis. With a sample size of 178 Canadian Chinese and 161 Caucasian university students, the present study found that in both ethnic groups, cultural norms rather than physical symptoms were a significant predictor of alcohol consumption patterns. This finding strongly suggests that alcohol consumption behavior can be better understood by a social/psychological rather than a biomedical approach. To effect changes in alcohol assumption patterns, it is suggested that cultural interpretations of alcohol use should be examined.
This study was done to determine the effects of alcohol consumption on selenium bioavailability in initially Se-depleted rats. Weanling male rats were fed a Se deficient basal diet for 4 weeks and then for the subsequent 4 weeks were supplemented at 0.031 mg Se/Kg or at 0.085 mg Se/Kg of diet in the form of high Se yeast. During the Se repletion period alcohol replaced medium chain triglycerides in the diet at three levels: 0%, 10% and 20% of calories. Dietary Se level significantly affected urinary Se, fecal Se, Se absorption, Se balance whole blood Se, whole blood glutathione peroxidase activity, liver Se concentration, and total liver Se content. Alcohol consumption significantly increased liver Se concentrations and total liver Se in rats fed the adequate Se diet. In rates fed the low Se diet, this pattern was not shown. There was a significant interaction between alcohol and Se level in terms of liver Se concentration and total liver Se. In the first week of Se repletion, fecal Se. Se absorption and Se balance were significantly higher in the 10% alcohol group fed the low Se repletion diet compared to rats given 0% and 20% alcohol in the same Se group. In the final week Se repletion the parameters of Se balance were not affected by alcohol consumption. Alcohol consumption did not influence whole blood Se and whole blood glutathione peroxidase activity; however alcohol consumption significantly reduced growth rate at both Se levels.

The influence of pre-pregnancy alcohol consumption on alcohol self-selection during pregnancy and lactation was examined in C57BL mice. One group of animals was given a two-bottle choice between water and a 10% w/v ethanol solution for three weeks prior to breeding, throughout pregnancy, and during lactation, while a second group was given the alcohol-water choice beginning on the first day of pregnancy. Relative alcohol intake (g ethanol/kg body weight) as well as alcohol "preference" decreased below pre-pregnancy levels during both pregnancy and lactation. That is, voluntary alcohol consumption was attenuated in pregnant and lactating mice, regardless of strain-typical pre-pregnancy high consumption. However, mice given a choice between alcohol and water prior to pregnancy did not decrease their alcohol consumption during pregnancy as much as mice not given the pre-pregnancy alcohol choice. There was no correlation between pre-pregnancy alcohol consumption and subsequent intake. The mechanism underlying decreased voluntary alcohol consumption during pregnancy remains to be elucidated, but it is clear that prior experience with alcohol influences the phenomenon.

When self-control resources are depleted ("ego depletion"), alcohol-seeking behavior becomes closely associated with automatic alcohol-related processing biases (e.g., Ostafin, Marlatt, & Greenwald, 2008). The current study aimed to replicate and extend these findings, and also to investigate whether the effects of ego depletion on drinking behavior would be mediated by temporary impairments in executive function or increases in impulsivity. Eighty heavy social drinkers (46 female) initially completed measures of automatic approach tendencies (stimulus response compatibility [SRC] task) and attentional bias (visual probe task) elicited by alcohol-related cues. Participants were then exposed to either an ego depletion manipulation or a control manipulation, before completing a bogus taste test in order to assess ad-lib alcohol consumption. In a subsequent testing session, we examined effects of the ego depletion manipulation (vs. control manipulation) on 3 aspects of executive function (inhibitory control, phonemic fluency, and delay discounting). Results indicated that the ego depletion manipulation increased ad-lib drinking, relative to the control manipulation. Automatic approach tendencies, but not attentional bias, predicted ad-lib drinking, although this effect was not moderated by ego depletion. Ego depletion had inconsistent effects on measures of executive function and impulsivity, and none of these measures mediated the effect of ego depletion on ad-lib drinking. However, the effect of ego depletion on ad-lib drinking was mediated by self-reported effort in suppressing emotion and thoughts during the manipulation. Implications for the effects of self-control strength on drinking behavior, and cognitive mediators of these effects, are discussed.

Alcohol is a recognized global risk factor for many diseases and injury types and a major contributor to disability and death. While cost-effective interventions do exist, many countries lack a comprehensive national alcohol harm reduction policy. The Arab world includes 22 diverse countries stretching from North Africa to Western Asia having varying dispositions with regards to alcohol sale and consumption. Epidemiological data is scattered and the picture on alcohol consumption remains blurry. This paper presents the findings of an extensive review conducted on all 22 Arab countries, specifically describing: (1) the density and methodology of alcohol-related peer-reviewed publications over the last two decades (1993-2013); (2) the epidemiology of alcohol consumption given all available data; and (3) the current status of policies in the region. Our search revealed a strikingly low number of alcohol-related peer-reviewed published studies - a total of 81 publications across 22 countries and two decades. Most studies are based on clinical or student samples. Where data is available, age of onset is low and drinking is frequent, in the absence of any available or enforced harm reduction policies. We submit that countries in the Arab region can be divided into four categories by alcohol ban and published data. One category includes countries where alcohol is not banned but data is absent, suggesting an ostrich-like response to a controversial behavior, or reflecting a weak research infrastructure and/or policy landscape. Evidence-informed recommendations and future directions for policy and research are discussed and tailored to countries' current stance on alcohol legislation and consumption. Given the particular vulnerability of youth to uptake of alcohol as well as the resulting short and long term consequences, the paper concludes by focusing on the implications of the findings for youth alcohol harm reduction.

The paper presents evidence on the impact of individual characteristics as well as regional macroeconomic factors on changes in fat, protein, alcohol and tobacco consumption, and on diet's diversity during the transition period 1994 - 2004 in Russia. The results from estimating first difference demand functions using Russian Longitudinal Monitoring Survey (RLMS) data suggest that individual characteristics such as initial consumption patterns, gender, education, household income, and access to a garden plot all have a significant impact on the consumption behaviour. Regarding the macroeconomic variables, inflation has a significant impact on alcohol and tobacco consumption, while unemployment significantly impacts only smoking behaviour. Russian consumers respond to own prices of fat and protein as well as to own prices of alcohol and tobacco but to a lesser extent. Analysis of subsamples based on different initial consumption patterns reveals significant heterogeneity in consumption responses.

Similarities between gambling disorder and substance use disorders have been extensively described. To date, however, few studies using large clinical samples have been carried out that reliably assess the relationship between different levels of alcohol consumption and gambling disorders. The present study aimed to assess the impact of baseline alcohol consumption levels on the clinical profile in a large sample of treatment-seeking individuals. Nine hundred and fifty-one consecutive outpatients diagnosed with gambling disorder according to DSM-IV criteria were compared after being included in three alcohol consumption groups (low risk, abuse and risk of dependence) based on their total raw scores on the AUDIT questionnaire. Results showed a high prevalence of risk of alcohol dependence in GD patients who were immigrants, unemployed, and had a low level of education. A positive linear trend was also found between alcohol consumption level and the prevalence of other current and life-time comorbid mental disorders, and for the presence of drug abuse. Statistically significant differences were found between the three alcohol consumption groups in terms of the evolution and severity of the gambling disorder, self-directedness personality trait, and levels of general psychopathology, hostility and paranoid ideation. In conclusion, the results showed an association between increased alcohol consumption and greater dysfunction.

This study aimed to verify differences in personality factors between abstainers and drinkers and between individuals with higher versus lower levels of alcohol consumption in the previous three months, and to test the predictive power of factors for any lifetime alcohol consumption and for at least monthly alcohol consumption. A total of 169 university students participated, of whom 66.7% were women, with a mean age of 21.2 years. Lifetime alcohol consumption was 90.1%; 42.3% had consumed at least twice in the previous three months; and 57.7% consumed alcohol at least monthly. Participants with less frequent consumption in the previous three months showed higher mean scores for personality factors involving socialization and achievement, while those that consumed more frequently scored higher on extroversion. A predictive model showed that increments in extroversion contributed to increased odds of drinking alcohol, while increments in achievement decreased the odds of drinking. Personality characteristics were able to distinguish between different groups of drinkers and predict the frequency of alcohol consumption.

Aims This study examined whether adolescents from Santiago, Chile who had never drunk alcohol differed from those who had drunk alcohol but who had never experienced an alcohol-related problem, as well as from those who had drunk and who had experienced at least one alcohol-related problem on a number of variables from four domains - individual, peers, parenting, and environmental. Design Cross-sectional. Setting Community based sample. Participants 909 adolescents from Santiago, Chile. Measurements Data were analyzed with multinomial logistic regression to compare adolescents who had never drunk alcohol (non-drinkers) with i) those that had drunk but who had experienced no alcohol-related problems (non-problematic drinkers) and ii) those who had drunk alcohol and had experienced at least one alcohol-related problem (problematic drinkers). The analyses included individual, peer, parenting, and environmental factors while controlling for age, sex, and socioeconomic status. Findings Compared to non-drinkers, both non-problematic and problematic drinkers were older, reported having more friends who drank alcohol, greater exposure to alcohol ads, lower levels of parental monitoring, and more risk-taking behaviors. In addition, problematic drinkers placed less importance on religious faith to make daily life decisions and had higher perceptions of neighborhood crime than non-drinkers. Conclusions Prevention programs aimed at decreasing problematic drinking could benefit from drawing upon adolescents’ spiritual sources of strength, reinforcing parental tools to monitor their adolescents, and improving environmental and neighborhood conditions.

Little is known about how parents make drinking decisions and weigh the risks and rewards of alcohol consumption in specific contexts. This qualitative study examined two questions: 1. What factors influence parental drinking decisions in different drinking contexts? 2. What do parents perceive as the risks and rewards of alcohol consumption in different drinking contexts? Purposive sampling was used to select sixty parents of children aged 10 or younger living in four mid-sized California cities. Data were collected via in-depth, semi-structured interviews. Many parents viewed drinking at family get-togethers or parties as protective of children, since the presence of multiple adults and children provide buffers when parents become intoxicated. In contrast, parents noted that drinking at home, and particularly drinking alone, transmitted potentially negative messages. Social pressures and contexts influence alcohol consumption among parents and could provide potential avenues for intervention against alcohol-related harms. PMID:26457048
Context The problem of alcohol misuse in Russia is immense; but nonetheless there is a tendency to exaggerate it, which is evident for inside observers. Such exaggeration tends to veil shortcomings of the health care system with responsibility shifted onto the patients, that is, self-inflicted diseases caused by excessive alcohol consumption. The aim of this report is to draw attention to the above-mentioned and other problems related to the alcohol consumption in Russia, not clearly perceptible from the literature, e.g. toxicity of some legally sold alcoholic beverages. Evidence Acquisition This report is based on a review of literature and observations by the author during the period 1970 - 2014. Results Predictable increase of alcohol consumption after the anti-alcohol campaign facilitated the economical reforms of the early 1990s: workers and some intelligentsia did not oppose privatizations of state-owned enterprises partly due to their drunkenness, involvement in workplace theft and use of equipment for profit, which was often tolerated by the management at that and earlier time. Conclusions Last time, a gradual change of the alcohol consumption pattern in Russia has been noticed: less heavy binge drinking of vodka, fortified wine and surrogates; more moderate consumption of beer.

Alcohol consumption is highly prevalent in university students. Early detection in future health professionals is important: their consumption might not only influence their own health but may determine how they deal with the implementation of preventive strategies in the future. The aim of this paper is to detect the prevalence of risky alcohol consumption in first- and last-degree year students and to compare their drinking patterns.Risky drinking in pharmacy students (n=434) was assessed and measured with the AUDIT questionnaire (Alcohol Use Disorders Identification Test). A comparative analysis between college students from the first and fifth years of the degree in pharmacy, and that of a group of professors was carried to see differences in their alcohol intake patterns.Risky drinking was detected in 31.3% of students. The highest prevalence of risky drinkers, and the total score of the AUDIT test was found in students in their first academic year. Students in the first academic level taking morning classes had a two-fold risk of risky drinking (OR=1.9 (IC 95%1.1-3.1)) compared with students in the fifth level. The frequency of alcohol consumption increases with the academic level, whereas the number of alcohol beverages per drinking occasion falls.Risky drinking is high during the first year of university. As alcohol consumption might decrease with age, it is important to design preventive strategies that will strengthen this tendency.

Tailgating has been associated with both problem drinking and high-risk behaviors. The purpose of this study was to determine if student participation in game day on-campus tailgating activities is associated with increased alcohol consumption. Employing a convenience sample of 567 university students, the authors compared the alcohol use patterns…

Aims: Alcohol consumption is known to be associated with risky sexual behaviours, but this relationship may be complex and bidirectional. We explored whether alcohol consumption leads to the consumer being rated as more attractive than sober individuals. Methods: Heterosexual social alcohol consumers completed an attractiveness-rating task, in which they were presented with pairs of photographs depicting the same individual, photographed while sober and after having consumed alcohol (either 0.4 or 0.8 g/kg), and required to decide which image was more attractive. Results: Photographs of individuals who had consumed a low dose of alcohol (equivalent to 250 ml of wine at 14% alcohol by volume for a 70 kg individual) were rated as more attractive than photographs of sober individuals. This was not observed for photographs of individuals who had consumed a high dose of alcohol. Conclusion: In addition to perceiving others as more attractive, a mildly intoxicated alcohol consumer may also be perceived as more attractive by others. This in turn may play a role in the relationship between alcohol consumption and risky sexual behaviour. PMID:25716115

The use of antidepressants for alcoholism in humans has been a matter of controversy in recent years. Despite the existence of an important co-morbidity for depression and alcoholism, some studies suggest that the use of antidepressants could worsen the prognosis of alcoholism. However, there is a lack of studies in animal models exploring this phenomenon. In the present study, we show how the 15-d treatment with fluoxetine (10 mg/kg) or venlafaxine (50 mg/kg) affected alcohol deprivation effect (ADE) and subsequent alcohol consumption. Initially, fluoxetine reduced ADE and venlafaxine did not affect it. However, in the following days, both antidepressants increased alcohol consumption, an effect that was found to last at least 5 wk. Fluoxetine treatment was shown to cause a locomotor sensitized response to a challenge dose of amphetamine (0.5 mg/kg), indicating the presence of a supersensitive dopaminergic transmission. In summary, antidepressant treatment may increase alcohol consumption in rats after a period of alcohol deprivation and this could be related to alterations in the reward circuitry. This finding confirms in an animal model previous reports in humans that may limit the use of antidepressants for alcoholism.

Rodent models implicate metabotropic glutamate receptors (mGluRs) and downstream signaling pathways in addictive behaviors through metaplasticity. One way mGluRs can influence synaptic plasticity is by regulating the local translation of AMPA receptor trafficking proteins via eukaryotic elongation factor 2 (eEF2). However, genetic variation in this pathway has not been examined with human alcohol use phenotypes. Among a sample of adults living in Detroit, Michigan (Detroit Neighborhood Health Study; n=788; 83% African American), 206 genetic variants across the mGluR–eEF2–AMPAR pathway (including GRM1, GRM5, HOMER1, HOMER2, EEF2K, MTOR, EIF4E, EEF2, CAMK2A, ARC, GRIA1 and GRIA4) were found to predict number of drinking days per month (corrected P-value <0.01) when considered as a set (set-based linear regression conducted in PLINK). In addition, a CpG site located in the 3′-untranslated region on the north shore of EEF2 (cg12255298) was hypermethylated in those who drank more frequently (P<0.05). Importantly, the association between several genetic variants within the mGluR–eEF2–AMPAR pathway and alcohol use behavior (i.e., consumption and alcohol-related problems) replicated in the Grady Trauma Project (GTP), an independent sample of adults living in Atlanta, Georgia (n=1034; 95% African American), including individual variants in GRM1, GRM5, EEF2, MTOR, GRIA1, GRIA4 and HOMER2 (P<0.05). Gene-based analyses conducted in the GTP indicated that GRM1 (empirical P<0.05) and EEF2 (empirical P<0.01) withstood multiple test corrections and predicted increased alcohol consumption and related problems. In conclusion, insights from rodent studies enabled the identification of novel human alcohol candidate genes within the mGluR–eEF2–AMPAR pathway. PMID:26101849

The present pilot study examined the effects of alcohol commercials shown in movie theaters on the alcohol consumption of young adults who see these commercials. A two (alcohol commercials vs. nonalcohol commercials) by two (high weekly alcohol consumption vs. low weekly alcohol consumption) between-participant design was used, in which 184 young adults (age: 16-28 years) were exposed to a movie that was preceded by either alcohol commercials or nonalcohol commercials. Participants' actual alcohol consumption while watching the movie ("Watchmen") was examined. An analysis of variance (ANOVA) was conducted to examine the effects of the commercial condition on alcohol consumption. An interaction effect was found between commercial condition and weekly alcohol consumption (p < .001). Alcohol consumption among high weekly alcohol drinkers was higher in the alcohol commercial condition than in the nonalcohol commercial condition, whereas no differences were found in alcohol consumption between commercial conditions among low weekly alcohol drinkers. No gender differences were found in the association between exposure to alcohol commercials, weekly drinking, and alcohol use. Thus, exposure to alcohol commercials prior to a movie in a movie theater can directly influence alcohol consumption among high weekly alcohol consumers.

The objective of this study was to assess the relationship between alcohol availability, as measured by the density of off-premise alcohol outlets, and alcohol consumption in Los Angeles county and southern Louisiana, USA. Consumption information was collected through a telephone survey of 2,881 households in Los Angeles county and pre-Katrina southern Louisiana, nested within 220 census tracts. Respondents' addresses were geo-coded and both neighbourhood (census tracts and buffers of varying sizes) and individual (network distance to the closest alcohol outlet) estimates of off-sale alcohol outlet density were computed. Alcohol outlet density was not associated with the percentage of people who were drinkers in either site. Alcohol outlet density was associated with the quantity of consumption among drinkers in Louisiana but not in Los Angeles. Outlet density within a one-mile buffer of the respondent's home was more strongly associated with alcohol consumption than outlet density in the respondent's census tract. The conclusion is that the relationship between neighbourhood alcohol outlet density and alcohol consumption is complex and may vary due to differences in neighbourhood design and travel patterns.

This paper identifies the variables associated with alcohol-related fatal traffic crashes (AFTC) in Spain. In addition, and for the first time in this country, these variables are used to describe the trend in AFTC, and to study the relationship between AFTC and alcohol consumption over the period 1976-1993. To this end, official data were obtained from the Traffic Department (Dirección General de Tráfico), the National Statistics Institute (Instituto Nacional de Estadística), and from international publications on trends in alcohol consumption. Nighttime fatal crashes (NFC) and male-driver single-vehicle nighttime fatal crashes (MNFC) were strongly associated with AFTC rates in Spain. A further finding was the decrease in NFC and MNFC rates during the period 1978-1993, though this decrease proved of a lower magnitude than that observed for daytime crashes. No relationship was observed between alcohol consumption at the population level and NFC or MNFC rates. The fatal crash rate, particularly the daytime rate, showed a rise with wealth level, as measured by gross domestic product and national private consumption, and an inverse relationship with the unemployment rate. The relationship between the fatal crash rate and economic variables was due, in most part, to changes in vehicle-km travelled.

Many parents support the "supervised introduction" of alcohol to children. While initiation to regular alcohol consumption in early adolescence has been linked with alcohol-related problems in adult life, the findings from these studies cannot be extrapolated to early childhood.

Detecting patterns of maternal drinking that place fetuses at risk for fetal alcohol spectrum disorders (FASDs) is critical to diagnosis, treatment, and prevention but is challenging because information on antenatal drinking collected during pregnancy is often insufficient or lacking. Although retrospective assessments have been considered less favored by many researchers due to presumed poor reliability, this perception may be inaccurate because of reduced maternal denial and/or distortion. The present study hypothesized that fetal alcohol exposure, as assessed retrospectively during child adolescence, would be related significantly to prior measures of maternal drinking and would predict alcohol-related behavioral problems in teens better than antenatal measures of maternal alcohol consumption. Drinking was assessed during pregnancy, and retrospectively about the same pregnancy, at a 14-year follow-up in 288 African-American women using well-validated semistructured interviews. Regression analysis examined the predictive validity of both drinking assessments on pregnancy outcomes and on teacher-reported teen behavior outcomes. Retrospective maternal self-reported drinking assessed 14 years postpartum was significantly higher than antenatal reports of consumption. Retrospective report identified 10.8 times more women as risk drinkers (≥ one drink per day) than the antenatal report. Antenatal and retrospective reports were moderately correlated and both were correlated with the Michigan Alcoholism Screening Test. Self-reported alcohol consumption during pregnancy based on retrospective report identified significantly more teens exposed prenatally to at-risk alcohol levels than antenatal, in-pregnancy reports. Retrospective report predicted more teen behavior problems (e.g., attention problems and externalizing behaviors) than the antenatal report. Antenatal report predicted younger gestational age at birth and retrospective report predicted smaller birth size

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.

Alcoholic liver disease is an established, yet controversial, indication for liver transplantation. Although an abstinence period of up to 6 mo prior to transplantation is mandatory, alcohol relapse after transplantation is a common event. In case of recurrence of heavy drinking, graft survival is significantly impaired. Guidelines on detection and surveillance of alcohol consumption in this patient cohort are lacking. This review summarizes the challenge of patient selection as well as the current knowledge on established and novel alcohol biomarkers with special focus on liver transplant candidates and recipients.

The effects of alcohol on food and energy intake in human subjects have been the subject of a number of controlled studies recently. Unlike the evidence for other macronutrients, there is minimal evidence for any compensatory reduction in food intake in response to energy ingested as alcohol. In contrast, all studies testing intake within 1 h of preload ingestion report a higher intake of food following alcohol relative to energy-matched controls, although this short-term stimulatory effect is not evident if the test meal is delayed beyond 1 h. This time-course suggests that short-term stimulation of appetite may be mediated by the pharmacological action of alcohol on the appetite control system, either through enhanced orosensory reward or impaired satiety. In the long term, energy ingested as alcohol is additive to energy from other sources, suggesting that moderate alcohol consumption results in long-term passive over-consumption alongside short-term active over-consumption of energy through appetite stimulation. Despite the consistency of enhanced energy intake after moderate alcohol, evidence of an association between alcohol in the diet and obesity remains contentious, although the most recent results suggest that alcohol intake correlates with BMI. Future research needs to address this issue and clarify the mechanisms underlying appetite stimulation by alcohol.
Alcohol is widely consumed across the world in different cultural and social settings. Types of alcohol consumption differ between (a) light, only occasional consumption, (b) heavy chronic alcohol consumption, and (c) binge drinking as seen as a new pattern of alcohol consumption among teenagers and young adults. Heavy alcohol consumption is detrimental to many organs and tissues, including bones. Osteoporosis is regularly mentioned as a secondary consequence of alcoholism, and chronic alcohol abuse is established as an independent risk factor for osteoporosis. The review will present the different mechanisms and effects of alcohol intake on bone mass, bone metabolism, and bone strength, including alcoholism-related "life-style factors" such as malnutrition, lack of exercise, and hormonal changes as additional causative factors, which also contribute to the development of osteoporosis due to alcohol abuse.

Objectives Research has demonstrated that packaging which includes pictorial health warnings are more effective in altering smokers’ perceptions and intentions as well as changing smoking behaviours compared to text-only health warnings. However, very few studies have investigated the effectiveness of health warnings on alcoholic beverages Methods Participants (N = 60) viewed alcoholic beverages presenting one of three health warnings (No health warning, Text-only, Pictorial) and then responded to questions relating to level of fear arousal and their perceptions toward alcohol use. Results We found that pictorial health warnings were associated with significantly higher fear arousal, increased perceptions of the health risks of consuming alcohol as well as greater intentions to reduce and quit alcohol consumption compared to the control. Conclusions These novel findings suggest pictorial health warnings on alcoholic beverages may be an important way of making the public aware of the health risks of alcohol consumption. PMID:27105210

A survey by 150 trained medical students was carried out in 1986 on a random sample of adults from the electoral register of Cardiff. The survey explored attitudes, knowledge and behaviour over a wide range of health related topics. 4266 self-completed questionnaires were returned for analysis and this paper reports the answers to the question 'how much did you drink last week'. The total units of alcohol were calculated and the drinking characteristics of the respondents are presented by age, sex, marital status, social class, accommodation and occupation. The contribution that such community surveys play in the development of local alcohol policy is discussed.

The present study addresses the association between immigration from the former Soviet Union (FSU) and gender and alcohol consumption among a representative sample of young adults in Israel 2000. Previous studies that were conducted on FSU immigrants to Israel indicate higher consumption than that of resident Israelis and immigrants of earlier periods. The current study aims to assess alcohol consumption among FSU and resident Israelis five years later to determine whether the discrepancy in alcohol consumption stays consistent or reduces. In addition, gender differences in alcohol consumption among the Israeli society were examined as well, as a special case of socio-culture differences. The data came from the 2000 national survey of drinking in Israel. Of 5,004 Jewish Israelis, 532 were immigrants from the FSU who arrived since 1989, and 4,472 were resident Israelis. The FSU group was compared with resident Israelis, and males were compared to females on several drinking variables. Logistic regression was the principal method of analysis. Demographics and cultural variables as main effects or in interaction with FSU and gender were controlled. The FSU group was significantly more likely to report drinking in the last twelve months plus drinking in the last thirty days than resident Israelis. Women's reported drinking in the last twelve months was one fourth of men's and during the past thirty days was one fifth of men's. Further investigation on the associations between the success of FSU acculturation in the Israeli society and drinking patterns as well as attitudes toward women and gender differences in alcohol consumption may provide explanations for gender and immigration gaps in alcohol consumption.

Twenty-two 50-month-old rhesus monkeys were provided concurrent free access to an aspartame-sweetened 7% ethanol solution and an aspartame-sweetened vehicle before, during, and after social separation. Subjects had been reared for their first 6 months of life either without access to adults but with constant access to age mates (peer reared), a condition producing reduced exploration and increased fear-related behaviors, or as controls with their mothers; thereafter, all subjects received identical treatment. During home-cage periods, for 1 hr each day, 4 days a week, when the ethanol solution and vehicle were freely available, peer-reared subjects consumed significantly more alcohol than mother-reared subjects. When stress was increased via social separation, mother-reared animals increased their alcohol consumption to a level nearly as high as that of peer-reared monkeys. Average individual differences in alcohol consumption were markedly stable over time. In addition, there were strong positive correlations between alcohol consumption and distress behaviors. Biological indices of increased stress, such as plasma cortisol and corticotropin, were higher in peer-reared subjects. Within the peer- and mother-reared groups, these indices were positively correlated with alcohol consumption. The results suggest that early rearing experiences that predispose monkeys to increased fear-related behaviors produce excessive alcohol consumption under normal living conditions. Furthermore, a major challenge such as social separation increases alcohol consumption to levels producing intoxication even in monkeys not particularly vulnerable to stress.

ABSTRACT OBJECTIVE To describe the patterns of alcohol consumption in Brazilian adolescents. METHODS We investigated adolescents who participated in the Study of Cardiovascular Risks in Adolescents (ERICA). This is a cross-sectional, national and school-based study, which surveyed adolescents of 1,247 schools from 124 Brazilian municipalities. Participants answered a self-administered questionnaire with a section on alcoholic beverages consumption. Measures of relative frequency (prevalence), and their 95% confidence intervals, were estimated for the following variables: use of alcohol beverages in the last 30 days, frequency of use, number of glasses or doses consumed in the period, age of the first use of alcohol, and most consumed type of drink. Data were estimated for country and macro-region, sex, and age group. The module survey of the Stata program was used for data analysis of complex sample. RESULTS We evaluated 74,589 adolescents, who accounted for 72.9% of eligible students. About 1/5 of adolescents consumed alcohol at least once in the last 30 days and about 2/3 in one or two occasions during this period. Among the adolescents who consumed alcoholic beverages, 24.1% drank it for the first time before being 12 years old, and the most common type of alcoholic beverages consumed by them were drinks based on vodka, rum or tequila, and beer. CONCLUSIONS There is a high prevalence of alcohol consumption among adolescents, as well as their early onset of alcohol use. We also identified a possible change in the preferred type of alcoholic beverages compared with previous research. PMID:26910550

Previous field research has shown that individuals consumed more alcohol and at a faster rate in environments paired with loud music. Theoretically, this effect has been linked to approach/avoidance accounts of how music influences arousal and mood, but no work has tested this experimentally. In the present study, female participants (n = 45) consumed an alcoholic (4% alcohol-by-volume) beverage in one of three contexts: slow tempo music, fast tempo music, or a no-music control. Results revealed that, compared with the control, the beverage was consumed fastest in the two music conditions. Interestingly, whereas arousal and negative mood declined in the control condition, this was not the case for either of the music conditions, suggesting a downregulation of alcohol effects. We additionally found evidence for music to disrupt sensory systems in that, counterintuitively, faster consumption was driven by increases in perceived alcohol strength, which, in turn, predicted lower breath alcohol level (BrAL). These findings suggest a unique interaction of music environment and psychoactive effects of alcohol itself on consumption rate. Because alcohol consumed at a faster rate induces greater intoxication, these findings have implications for applied and theoretical work.

Alcohol-related injuries have been concerned worldwide. However, there have been no large cross-sectional epidemiologic studies. The aim of this study was to investigate the association between alcohol and the prevalence of injury according to gender in a representative sample of the South Korean population. This cross-sectional study was based on data obtained in the Korea National Health and Nutrition Examination Survey from 2010 to 2012. In total, 15,249 Korean adults (7128 men and 8112 women) aged 19 years or older were enrolled. Injury was defined as the incidence of an injury or intoxication within the year before completing the survey questionnaire. Univariate and multiple logistic regression analyses were conducted to analyze the relationship between alcohol consumption and the prevalence of injury. Heavy alcohol consumption and high-risk drinking were associated with a higher prevalence of injury in women (adjusted odds ratio [aOR] and corresponding 95% confidence interval [CI]: 2.48 [1.321, 4.656], 1.816 [1.136, 2.929], respectively), and Alcohol Use Disorders Identification Test (AUDIT) scores ≥20 were associated with a higher prevalence of injury in both men and women (aOR and 95% CI: 1.425 [1.004, 2.024] and 3.71 [2.067, 6.66], respectively). According to the AUDIT scores results, women who were injured reported significantly more high-risk drinking behaviors per month compared with those who were not injured. Gender disparities in the relationship between alcohol and the prevalence of injury were found. Indeed, future research using a prospective design should examine the causal relationship between alcohol consumption and the prevalence injury according to gender to confirm that alcohol is a risk factor for injury and to identify the possible mechanisms underlying this phenomenon.

Introduction Excessive alcohol consumption was responsible for approximately 4,300 annual deaths in the United States among people younger than 21 from 2006 through 2010. Underage drinking cost the United States $24.6 billion in 2006. Previous studies have shown that liquor is the most common type of alcohol consumed by high school students. However, little is known about the types of liquor consumed by youth or about the mixing of alcohol with energy drinks. Methods The 2011 Michigan Youth Tobacco Survey was used to assess usual alcohol beverage consumption and liquor consumption and the mixing of alcohol with energy drinks by Michigan high school students. Beverage preferences were analyzed by demographic characteristics and drinking patterns. Results Overall, 34.2% of Michigan high school students consumed alcohol in the past month, and 20.8% reported binge drinking. Among current drinkers, liquor was the most common type of alcohol consumed (51.2%), and vodka was the most prevalent type of liquor consumed by those who drank liquor (53.0%). The prevalence of liquor consumption was similar among binge drinkers and nonbinge drinkers, but binge drinkers who drank liquor were significantly more likely than nonbinge drinkers to consume vodka and to mix alcohol with energy drinks (49.0% vs 18.2%, respectively). Conclusions Liquor is the most common type of alcoholic beverage consumed by Michigan high school students; vodka is the most common type of liquor consumed. Mixing alcohol and energy drinks is common, particularly among binge drinkers. Community Guide strategies for reducing excessive drinking (eg, increasing alcohol taxes) can reduce underage drinking.

Background and purpose — Long-term alcohol intake is associated with various negative effects on capillary microcirculation and tissue perfusion. We hypothesized that alcohol consumption might be a risk factor for both the occurrence and the severity of rotator cuff tears (RCTs). Patients and methods — A case-control study was performed. We studied 249 consecutive patients (139 men and 110 women; mean age 64 (54–78) years) who underwent arthroscopic rotator cuff repair. Tear size was determined intraoperatively. The control group had 356 subjects (186 men and 170 women; mean age 66 (58–82) years) with no RCT. All participants were questioned about their alcohol intake. Participants were divided into: (1) non-drinkers if they consumed less than 0.01 g of ethanol per day, and (2) moderate drinkers and (3) excessive drinkers if women (men) consumed > 24 g (36 g) per day for at least 2 years. Results — Total alcohol consumption, wine consumption, and duration of alcohol intake were higher in both men and women with RCT than in both men and women in the control group. Excessive alcohol consumption was found to be a risk factor for the occurrence of RCT in both sexes (men: OR = 1.7, 95% CI: 1.2–3.9; women: OR = 1.9, 95% CI: 0.94–4.1). Massive tears were associated with a higher intake of alcohol (especially wine) than smaller lesions. Interpretation — Long-term alcohol intake is a significant risk factor for the occurrence and severity of rotator cuff tear in both sexes. PMID:26610042

Digital interventions are available to help people reduce their alcohol consumption, but it is not known who uses these interventions and how this treatment-seeking group compares with the general population of drinkers. The study objective was to compare the socio-demographic and drinking characteristics of users of the 'Drinks Meter' smartphone app with the general population of drinkers in England and website users of the same intervention. Data were used from the Drinks Meter app and website, and a nationally representative cross-sectional survey in England (Alcohol Toolkit Study). Participants were drinkers aged 16+ in England. Data were collected on participants' age, gender, region, sexual orientation, social grade and AUDIT score. Regression analyses were conducted to assess differences in socio-demographic and drinking characteristics between samples. Drinks Meter app users, compared with drinkers of the general population, were younger, more likely to be from the South, not heterosexual, less likely to be of a lower social grade and had a higher mean AUDIT score. Drinks Meter app users were younger than website users and reported greater alcohol consumption and related harms. Drinkers using the Drinks Meter app are more likely to be younger and report greater alcohol consumption and related harms compared with the general population of drinkers in England and website users of the same intervention. Apps that provide feedback on drinking appear to be reaching those who report greater alcohol consumption and related harms.

In this chapter, we review the effects of global null mutant and overexpressing transgenic mouse lines on voluntary self-administration of alcohol. We examine approximately 200 publications pertaining to the effects of 155 mouse genes on alcohol consumption in different drinking models. The targeted genes vary in function and include neurotransmitter, ion channel, neuroimmune, and neuropeptide signaling systems. The alcohol self-administration models include operant conditioning, two- and four-bottle choice continuous and intermittent access, drinking in the dark limited access, chronic intermittent ethanol, and scheduled high alcohol consumption tests. Comparisons of different drinking models using the same mutant mice are potentially the most informative, and we will highlight those examples. More mutants have been tested for continuous two-bottle choice consumption than any other test; of the 137 mouse genes examined using this model, 97 (72%) altered drinking in at least one sex. Overall, the effects of genetic manipulations on alcohol drinking often depend on the sex of the mice, alcohol concentration and time of access, genetic background, as well as the drinking test.

The aim of this study was to evaluate the magnesium (Mg) status of male subjects consuming moderate amounts of alcohol (n = 14) in comparison with that of a group of non-consumers of alcohol (n = 10). Plasma ionized Mg levels and total erythrocyte Mg content were determined as well as the excretion of Mg in urine before and after an oral loading test. Intake of Mg via food and water was estimated using a one-week dietary records. The results showed a significantly higher, alcohol dose-related excretion of Mg and Ca (calcium) in the urine after the oral Mg load among consumers of alcohol. Although the study is based on a small number of subjects with differences in smoking habits, it is suggested that alcohol consumption even in moderate amounts could contribute to Mg deficiency.

This study was done to determine the effects of alcohol ingestion on Se bioavailability in initially Se-depleted rats. Weanling male rats were fed a Se deficient (0.012 mg/kg) basal diet for 4 weeks and then for the subsequent 4 weeks were supplemented at 0.031 mg Se/kg or at 0.085 mg Se/kg of diet in the form of high Se yeast. During the Se repletion period alcohol replaced medium chain triglycerides in the diet at 3 levels: 0%, 10%, and 20% of calories. Dietary Se level significantly (P < .0001) affected urinary Se, fecal Se, Se absorption, Se balance, whole blood Se, whole blood glutathione peroxidase activity, and liver Se. In rats fed the higher Se diet total liver Se increased 50% when 20% rather than 0% alcohol was given. In rats fed the lower Se diet total liver Se decreased 12% as dietary alcohol increased from 0 to 20%. There was a significant (P < .0015) interaction between alcohol and Se level. All the other parameters for Se bioavailability were not affected by alcohol consumption. However, alcohol consumption significantly reduced growth rate at both Se levels.

We reviewed 143 papers that described the relationship between moderate drinking of alcohol and some aspect of cognition. Two types of papers were found: (1) those that provided ratios of risk between drinkers and nondrinkers (74 papers in total) and (2) those that, although they did not provide such ratios, allowed cognition in drinkers to be rated as “better,” “no different,” or “worse” than cognition in nondrinkers (69 papers in total). The history of research on moderate drinking and cognition can be divided into two eras: 1977–1997 and 1998–present. Phase I (1977–1997) was the era of neuropsychological evaluation involving mostly young to middle-aged (18–50 years old) subjects. Although initial studies indicated moderate drinking impaired cognition, many later studies failed to confirm this, instead finding no difference in cognition between drinkers and nondrinkers. Phase II (1998–present) was and is the era of mental status exam evaluation involving mostly older (≥55 years old) subjects. These studies overwhelmingly found that moderate drinking either reduced or had no effect on the risk of dementia or cognitive impairment. When all the ratios of risk from all the studies in phase II providing such ratios are entered into a comprehensive meta-analysis, the average ratio of risk for cognitive risk (dementia or cognitive impairment/decline) associated with moderate “social” (not alcoholic) drinking of alcohol is 0.77, with nondrinkers as the reference group. The benefit of moderate drinking applied to all forms of dementia (dementia unspecified, Alzheimer’s disease, and vascular dementia) and to cognitive impairment (low test scores), but no significant benefit against cognitive decline (rate of decline in test scores) was found. Both light and moderate drinking provided a similar benefit, but heavy drinking was associated with nonsignificantly higher cognitive risk for dementia and cognitive impairment. Although the meta

The authors have previously found an increased risk of ischemic heart disease (IHD) in men with the Lewis phenotype Le(a[minus]b[minus]) and suggested that the Lewis blood group has a close genetic relation with insulin resistance. The authors have investigated whether any conventional risk factors explain the increased risk in Le(a[minus]b[minus]) men. 3,383 men aged 53-75 years were examined in 1985-86, and morbidity and mortality during the next 4 years were recorded. At baseline, the authors excluded 343 men with a history of myocardial infarction, angina pectoris, intermittent claudication, or stroke. The potential risk factors examined were alcohol consumption, physical activity, tobacco smoking, serum cotinine, serum lipids, body-mass index, blood pressure, prevalence of hypertension and non-insulin-dependent diabetes mellitus, and social class. In 280 (9.6%) men with Le(a[minus]b[minus]), alcohol was the only risk factor significantly associated with risk of IHD. There was a significant inverse dose-effect relation between alcohol consumption and risk; trend tests, with adjustment for age, were significant for fatal IHD (p=0.02), all IHD (p=0.03), and all causes of death (p=0.02). In 2649 (90.4%) men with other phenotypes, there was a limited negative association with alcohol consumption. In Le(a[minus]b[minus]) men, a group genetically at high risk of IHD, alcohol consumption seems to be especially protective. The authors suggest that alcohol consumption may modify insulin resistance in Le(a[minus]b[minus]) men.

The effect of alcohol consumption on the risk of gastric cancer (GC) has not yet been fully elucidated, and an aldehyde dehydrogenase 2 (ALDH2) polymorphism, rs671, is a genetic variant that influences alcohol consumption in East Asians. Additionally, the discrepancy between the Helicobacter pylori (H. pylori) infection prevalence and GC incidence across Asian countries has not been explained. This study evaluated the effects of alcohol consumption and genetic susceptibility to defective acetaldehyde metabolism on the GC risk and their interactions with H. pylori infection. This study included 450 Korean GC cases and 1,050 controls recruited at the National Cancer Center. Data for 795 patients and 4,893 controls were used for further confirmation of the effect of rs671. Increased GC risks were evident for rs671 A allele carriers (odds ratio (OR), 1.23; 95% confidence interval (CI), 1.08-1.41) and H. pylori-infected individuals (OR, 7.07; 95% CI, 4.60-10.86), but no dose-response association with alcohol consumption was observed. Furthermore, the interactions between these factors were not significant. This study has demonstrated that alcohol consumption and rs671 should be considered simultaneously when assessing the GC risk. Additionally, alcohol-related factors were not found to interact with H. pylori infection, and further studies evaluating other environmental factors are required to explain the Asian enigma.

While the adverse health and economic consequences attributable to alcohol consumption are widely acknowledged, its impact on psychological wellbeing is less well understood. This is to a large extent due to the challenge of establishing causal effects of alcohol consumption when using standard single-equation econometric analyses. Using a unique dataset collected in 2010/11 of 18,000 individuals and also community characteristics from nine countries of the former Soviet Union, a region with a major burden of alcohol related ill health, we address this problem by employing an instrumental variable approach to identify any causal effects of alcohol consumption on mental well-being. The availability of 24-h alcohol sales outlets in the neighbourhood of the individuals is used as an instrument, based on theoretical reasoning and statistical testing of its validity. We find that increased alcohol consumption decreases well-being and that ignoring endogeneity leads to underestimation of this effect. This finding adds a further and previously under-appreciated dimension to the expected benefits that could be achieved with more effective alcohol policy in this region.

Research has demonstrated a link between alcohol use and multiple forms of risky sexual behavior, particularly among college-age individuals. Studies have also linked heavy alcohol use to other problems, such as impaired consciousness resulting from an alcohol-induced blackout, which may impact sexual decision making. However, research has rarely examined sexual risk taking (SRT) in relation to blackouts, nor has it examined this construct during the precollege transition (i.e., the interval of time between high school graduation and college matriculation). This study examined the intersection between alcohol-involved SRT, blackouts, and gender in a sample of precollege individuals with prior alcohol use (N = 229; 54% male, 63% White). Results indicated that, despite drinking less per occasion, women reporting recent blackouts were at increased risk for experiencing unwanted, unsafe, and regretted sexual behaviors compared to men with recent blackouts and their peers with no recent blackouts. Women with recent blackouts also reported differences in alcohol expectancies that may increase their risk for experiencing negative consequences while drinking, including higher social expectancies and lower negative expectancies of danger. Future directions for research and implications for precollege interventions are discussed.
