Episodic Drinking (episodic + drinking)
Kinds of Episodic Drinking Selected AbstractsAlcohol, suppressed anger and violenceADDICTION, Issue 9 2010Thor Norström ABSTRACT Aims Is alcohol related causally to violence, and if so, is the effect of drinking contingent on suppressed anger such that it is strongest among individuals who are highly inclined to withhold angry feelings? We addressed these questions by analysing panel data using a method that diminishes the effects of confounding factors. Design We analysed data on heavy episodic drinking and violent behaviour from the second (1994) and third (1999) waves of the Young in Norway Longitudinal Study (n = 2697; response rate: 67%). The first difference method was applied to estimate the association between these behaviours, implying that changes in the frequency of violence were regressed on changes in the frequency of drinking. Hence, the effects of time-invariant confounders were eliminated. Analyses were conducted for the whole sample, and for groups scoring low, medium and high on a short version of the STAXI anger suppression scale. Findings Changes in drinking were related positively and significantly to changes in violent behaviour, but the alcohol effect varied with the level of suppressed anger: it was strongest in the high-anger group (elasticity estimate = 0.053, P = 0.011) and weakest (and insignificant) in the low-anger group (elasticity estimate = 0.004, P = 0.806). Conclusions Alcohol use may be related causally to violence, but the effect of drinking is confined to individuals who are inclined to suppress their angry feelings. [source] Gender and alcohol consumption: patterns from the multinational GENACIS projectADDICTION, Issue 9 2009Richard W. Wilsnack ABSTRACT Aims To evaluate multinational patterns of gender- and age-specific alcohol consumption. Design and participants Large general-population surveys of men's and women's drinking behavior (n's > 900) in 35 countries in 1997,2007 used a standardized questionnaire (25 countries) or measures comparable to those in the standardized questionnaire. Measurements Data from men and women in three age groups (18,34, 35,49, 50,65) showed the prevalence of drinkers, former drinkers, and lifetime abstainers; and the prevalence of high-frequency, high-volume, and heavy episodic drinking among current drinkers. Analyses examined gender ratios for prevalence rates and the direction of changes in prevalence rates across age groups. Findings Drinking per se and high-volume drinking were consistently more prevalent among men than among women, but lifetime abstention from alcohol was consistently more prevalent among women. Among respondents who had ever been drinkers, women in all age groups were consistently more likely to have stopped drinking than men were. Among drinkers, the prevalence of high-frequency drinking was consistently greatest in the oldest age group, particularly among men. Unexpectedly, the prevalence of drinking per se did not decline consistently with increasing age, and declines in high-volume and heavy episodic drinking with increasing age were more typical in Europe and English-speaking countries. Conclusions As expected, men still exceed women in drinking and high-volume drinking, although gender ratios vary. Better explanations are needed for why more women than men quit drinking, and why aging does not consistently reduce drinking and heavy drinking outside Europe and English-speaking countries. [source] Hostility, drinking pattern and mortalityADDICTION, Issue 1 2008Stephen H. Boyle ABSTRACT Aims This study examined the association of hostility to drinking pattern and whether this association mediated the relation of hostility to mortality. Participants and design Subjects were 3326 current drinkers from the Vietnam Experience Study cohort who were followed for vital status. Setting United States. Measurements Hostility was measured by an abbreviated version of the Cook,Medley Hostility Scale (ACM). The alcohol variables were total monthly intake of alcohol, drinking frequency, drinks per drinking day and drinking , 5 drinks on at least one occasion in the past month (i.e. heavy episodic drinking). Findings Regression analyses showed associations between the ACM and total monthly intake of alcohol (P < 0.0001), drinks per drinking day (P < 0.0001) and heavy episodic drinking (P < 0.0001), but not with frequency of drinking days. Hostility, drinks per drinking day, heavy episodic drinking and total monthly alcohol intake were also associated with all-cause mortality (all Ps < 0.0001). Further analyses showed that drinking pattern, particularly drinks per drinking day, may account partially for the relation of hostility to mortality. Conclusions High hostility is associated with elevated mortality and a deleterious drinking pattern characterized by relatively high intake per drinking occasion. Drinking pattern could help explain the relationships between hostility and health. [source] Drinking patterns, drinking contexts and alcohol-related aggression among late adolescent and young adult drinkersADDICTION, Issue 7 2005Samantha Wells ABSTRACT Aims The main objectives of this study were to determine: (1) the relative roles of heavy episodic drinking (HED), drinking frequency and drinking volume in explaining alcohol-related aggression and (2) whether drinking context variables (i.e. usual drinking locations, typical drinking companions and extent of peer drinking) confound or modify the relationship between HED and alcohol-related aggression or whether they predict alcohol-related aggression independently. Design A secondary analysis of the US National Longitudinal Survey of Youth was conducted. Alcohol-related aggression (denoted fights after drinking) was measured based on self-reports of arguments or fights that occurred during or after drinking in the previous 12 months. Participants A composite sample of drinkers, ages 17,21, from the 1994, 1996 and 1998 Young Adult surveys (n = 738) was used. Findings Frequency of drinking and drinking volume largely confounded the association between HED and fights after drinking. Usually drinking in public locations away from home versus private locations was found to be significantly associated with a greater likelihood of fights after drinking among females. Among males, usual drinking location modified the relationship between drinking frequency and alcohol-related aggression, with the greatest risk of aggression for males who drank frequently and usually drank in public locations away from home. Conclusions Programs designed to reduce drinking frequency in this population and to increase the safety of drinking locations in public places away from home may prove to be beneficial in reducing alcohol-related aggression. [source] Social marketing in action,geodemographics, alcoholic liver disease and heavy episodic drinking in Great BritainINTERNATIONAL JOURNAL OF NONPROFIT & VOLUNTARY SECTOR MARKETING, Issue 3 2007Jane Powell This paper explores the use of geodemographic population classifications to identify and predict ,hotspots' of Great Britain (England, Scotland and Wales) prone to greater than expected alcoholic liver disease. MOSAIC geodemographic codes were overlaid onto Hospital Episode Statistics (HES) for Great Britain. The HES data included gender, MOSAIC Type, MOSAIC Code, postal and local authority district, month and year of birth, ethnic origin, Primary Care Trust and GP code. Analysis demonstrated that some geodemographic classifications of the population were over-represented for alcoholic liver disease episodes. These groups had low socio-economic and socio-cultural status, lived in areas of high deprivation and disadvantage. Manchester followed by Liverpool and Hull had the highest estimated patient group size in England and Hart, Surrey Heath and Wokingham the three lowest (indicating low expected levels of alcoholic liver disease compared with average). Analysis of the same data was also carried out at postcode level for Manchester indicating ,hotspots' for alcoholic level disease at street level. This analysis exemplifies the ways in which geodemographic data might be usefully applied to routine health service data to enhance service planning, delivery and improved targeting of information in harder to reach populations.

Brager Background:, Chronic ethanol abuse is associated with disrupted circadian rhythms and sleep. Ethanol administration impairs circadian clock phase-resetting, suggesting a mode for the disruptive effect of alcohol abuse on circadian timing. Here, we extend previous studies to explore the effects of chronic forced ethanol on photic phase-resetting, photic entrainment, and daily locomotor activity patterns in C57BL/6J mice. Methods:, First, microdialysis was used to characterize the circadian patterns of ethanol uptake in the suprachiasmatic (SCN) circadian clock and correlate this with systemic ethanol levels and episodic drinking of 10 or 15% ethanol. Second, the effects of chronic forced ethanol drinking and withdrawal on photic phase-delays of the circadian activity rhythm were assessed. Third, the effects of chronic ethanol drinking on entrainment to a weak photic zeitgeber (1 minute of 25 lux intensity light per day) were assessed. This method was used to minimize any masking actions of light that could mask ethanol effects on clock entrainment. Results:, Peak ethanol levels in the SCN and periphery occurred during the dark phase and coincided with the time when light normally induces phase-delays in mice. These delays were dose-dependently inhibited by chronic ethanol and its withdrawal. Chronic ethanol did not impede re-entrainment to a shifted light cycle but affected entrainment under the weak photic zeitgeber and disrupted the daily pattern of locomotor activity. Conclusions:, These results confirm that chronic ethanol consumption and withdrawal markedly impair circadian clock photic phase-resetting. Ethanol also disturbs the temporal structure of nighttime locomotor activity and photic entrainment. Collectively, these results suggest a direct action of ethanol on the SCN clock. [source] Heavy Episodic Drinking and Alcohol Consumption in French Colleges: The Role of Perceived Social NormsALCOHOLISM, Issue 1 2010Lionel Riou França Background:, The effect of normative perceptions (social norms) on heavy episodic drinking (HED) behavior is well known in the U.S. college setting, but little work is available in other cultural contexts. The objective of this study is therefore to assess whether social norms of alcohol use are related to HED in France, taking account of other influential predictors. Methods:, A cross-sectional survey was carried out among 731 second-year university students in the Paris region to explore the role of 29 potential alcohol use risk factors. The probability of heavy episodic drinking and the frequency of HED among heavy episodic drinkers were modeled independently. Monthly alcohol consumption was also assessed. Results:, Of the students, 56% overestimate peer student prevalence of HED (37% for alcohol drinking prevalence). HED frequency rises with perceived peer student prevalence of HED. Other social norms associated with HED are perceived friends' approval of HED (increasing both HED probability and HED frequency) and perceived friend prevalence of alcohol drinking (increasing HED probability only). Cannabis and tobacco use, academic discipline, gender, and the number of friends are also identified as being associated with HED. Conclusions:, Overestimation of peer student prevalence is not uncommon among French university students. Furthermore, perceived peer student prevalence of HED is linked to HED frequency, even after adjusting for other correlates. Interventions correcting misperceived prevalences of HED among peer students have therefore the potential to reduce the frequency of HED in this population. [source] Projected Alcohol Dose Influences on the Activation of Alcohol Expectancies in College DrinkersALCOHOLISM, Issue 7 2009Jennifer P. Read Background:, Alcohol expectancies have been linked to drinking behavior in college students, and vary according to a number of factors, including projected dose of alcohol. Research using Multidimensional Scaling (MDS) suggests that drinking may be influenced by activation of differing expectancy dimensions in memory, yet studies have not examined expectancy activation according to projected alcohol doses. Methods:, The present study used Individual Differences Scaling (INDSCAL) to map expectancy networks of college students (n = 334) who imagined varied drinking at high and low alcohol doses. Expectancy activation was modeled by dose, as well as by gender and by drinking patterns (typical quantity, blood alcohol content, heavy episodic drinking, and alcohol consequences). Expectancies were organized along positive,negative and arousal,sedation dimensions. Anticipation of a high dose of alcohol was associated with greater emphasis on the arousal,sedation dimension, whereas anticipation of a lower dose was associated with greater emphasis on the positive,negative dimension. Results:, Across heavy, medium, and light drinkers, expectancy dimensions were most distinguishable at higher doses; activation patterns were more similar across drinking groups at lighter doses. Modest evidence for the influence of gender on activation patterns was observed. Findings were consistent across alcohol involvement indices. Conclusions:, These data suggest that both dimensionality and context should be considered in the refinement of interventions designed to alter expectancies in order to decrease hazardous drinking. [source] Disparities in Alcohol-Related Problems Among White, Black, and Hispanic AmericansALCOHOLISM, Issue 4 2009Nina Mulia Background:, This study assesses racial/ethnic disparities in negative social consequences of drinking and alcohol dependence symptoms among white, black, and Hispanic Americans. We examine whether and how disparities relate to heavy alcohol consumption and pattern, and the extent to which social disadvantage (poverty, unfair treatment, and racial/ethnic stigma) accounts for observed disparities. Methods:, We analyzed data from the 2005 U.S. National Alcohol Survey, a nationally representative telephone-based survey of adults ages 18 and older (N = 6,919). Given large racial/ethnic differences in abstinence rates, core analyses were restricted to current drinkers (N = 4,080). Logistic regression was used to assess disparities in alcohol-related problems at 3 levels of heavy drinking, measured using a composite variable incorporating frequency of heavy episodic drinking, frequency of drunkenness, and maximum amount consumed in a single day. A mediational approach was used to assess the role of social disadvantage. Results:, African American and Hispanic drinkers were significantly more likely than white drinkers to report social consequences of drinking and alcohol dependence symptoms. Even after adjusting for differences in heavy drinking and demographic characteristics, disparities in problems remained. The racial/ethnic gap in alcohol problems was greatest among those reporting little or no heavy drinking, and gradually diminished to nonsignificance at the highest level of heavy drinking. Social disadvantage, particularly in the form of racial/ethnic stigma, appeared to contribute to racial/ethnic differences in problems. Conclusions:, These findings suggest that to eliminate racial/ethnic disparities in alcohol-related problems, public health efforts must do more than reduce heavy drinking. Future research should address the possibility of drink size underestimation, identify the particular types of problems that disproportionately affect racial/ethnic minorities, and investigate social and cultural determinants of such problems. [source] Caffeinated Cocktails: Energy Drink Consumption, High-risk Drinking, and Alcohol-related Consequences among College StudentsACADEMIC EMERGENCY MEDICINE, Issue 5 2008Mary Claire O'Brien MD Abstract Objectives:, The consumption of alcohol mixed with energy drinks (AmED) is popular on college campuses in the United States. Limited research suggests that energy drink consumption lessens subjective intoxication in persons who also have consumed alcohol. This study examines the relationship between energy drink use, high-risk drinking behavior, and alcohol-related consequences. Methods:, In Fall 2006, a Web-based survey was conducted in a stratified random sample of 4,271 college students from 10 universities in North Carolina. Results:, A total of 697 students (24% of past 30-day drinkers) reported consuming AmED in the past 30 days. Students who were male, white, intramural athletes, fraternity or sorority members or pledges, and younger were significantly more likely to consume AmED. In multivariable analyses, consumption of AmED was associated with increased heavy episodic drinking (6.4 days vs. 3.4 days on average; p < 0.001) and twice as many episodes of weekly drunkenness (1.4 days/week vs. 0.73 days/week; p < 0.001). Students who reported consuming AmED had significantly higher prevalence of alcohol-related consequences, including being taken advantage of sexually, taking advantage of another sexually, riding with an intoxicated driver, being physically hurt or injured, and requiring medical treatment (p < 0.05). The effect of consuming AmED on driving while intoxicated depended on a student's reported typical alcohol consumption (interaction p = 0.027). Conclusions:, Almost one-quarter of college student current drinkers reported mixing alcohol with energy drinks. These students are at increased risk for alcohol-related consequences, even after adjusting for the amount of alcohol consumed. Further research is necessary to understand this association and to develop targeted interventions to reduce risk. [source] | ||||||||||
