BACKGROUND/AIMS: Childhood cognition predicts adult morbidity and mortality, potentially working through health behaviours. This study investigates if childhood cognition influences life course (i) non-drinking and (ii) binge drinking and pathways through which this might act-namely, childhood behaviour problems, adult social position and educational qualifications. METHODS: Prospective cohort of British births in March 1958, with information on cognition at 7, 11 and 16 years and alcohol use at 23, 33 and 42 years. Non-drinkers drank "infrequently/on special occasions" or "never". Binge drinkers consumed >or=10 units/occasion (men) and >or=7 units/occasion (women). RESULTS: Lower cognitive ability increased the odds of non-drinking at each adult survey (for example, for men at 42 years OR 1.52 (95% CI 1.34 to 1.72) per SD decrease in 7-year maths). Associations remained after adjustment for pathway factors (i) behaviour problems, (ii) adult social position and (iii) educational qualifications. Decreased ability rank across childhood (7-16 years) also increased odds of non-drinking at 42 years, but the association operated via pathway factors. Lower 7-year ability elevated the odds of 42-year binge drinking, operating via pathway factors. Declining ability rank across childhood also increased the odds of adult binge drinking; associations operated through behavioural problems, adult social position and qualifications. In women, the decline in risk of binge drinking from an age 23-year peak to 42 years was associated with higher 7-year score. CONCLUSIONS: Poorer childhood cognition was associated with non-drinking and binge drinking up to the early 40s. Associations between childhood cognition and drinking status may mediate between childhood cognition and adult health.

OBJECTIVE: To investigate (1) social gradients in non-drinking and binge drinking, and (2) changes in social gradients in drinking with increasing age. METHODS: British men and women born during the same week in March 1958 were prospectively followed up to adulthood. The frequency and amount of alcohol use were recorded at age 23, 33 and 42 years. Abstainers "never" drank, binge drinkers consumed >or=10 units (men) and >or=7 units (women) per occasion. Educational qualifications and occupation were reported at age 23 and 33 years. Logistic and repeated-measures models were used to investigate associations between social position and drinking status at single and multiple ages in adulthood. RESULTS: Less educated men and women had greater odds of being non-drinkers at each age in adulthood, with similar gradients at ages 23-42 years. At 23 years of age, men without qualifications had 2.94 times greater odds of non-drinking than men with higher qualifications. Less educated men had greater odds of binge drinking, and gradients did not change at ages 23-42 years. At age 23 years, less educated women had lower odds of binge drinking (odds ratio (OR) 0.67 for women with no qualifications) than women with higher qualifications. By age 42 years, the gradient reversed, and less educated women had higher odds of binge drinking (OR 2.68). CONCLUSIONS: Stable gradients in non-drinking and trends in gradients in binge drinking may reinforce alcohol-related health inequalities over time.

AIMS: To assess (i) continuities in binge drinking across adulthood and (ii) the association between adolescent drinking level and adult binge drinking. DESIGN: Population-based prospective birth cohort. SETTING: England, Scotland and Wales. PARTICIPANTS: All births during one week in March 1958 (n = 8520 in analysis). MEASUREMENTS: Alcohol consumption reported at 16, 23, 33 and 42 years. Binge drinkers were identified by dividing number of units of alcohol consumed in the last week by usual drinking frequency, with limits of >/=10 units/occasion for men and >/=7 for women. FINDINGS: Four in five cohort members drank alcohol at least twice a month. Prevalences of binge drinking at 23, 33 and 42 years among men were 37%, 28% and 31% and among women 18%, 13% and 14%. Most binge drinkers in adulthood changed drinking status during this period. Nevertheless, binge drinking at age 23 increased the odds of binge drinking at 42 years: odds ratio (OR) 2.10 (95% CI 1.85, 2.39) for men; OR 1.56 (95% CI 1.29,1.89) for women. Women who rarely or never drank aged 16 were less likely than light drinkers (0-2 units/week) to binge drink as adults, OR at 23 years 0.65 (95% CI 0.55, 0.77). Men who were heavier drinkers (>/=7 units/week) at 16 years were more likely than light drinkers to binge drink throughout adulthood; at 42 years, OR 1.64 (95% CI 1.33, 2.08). CONCLUSIONS: Binge drinking is common in British men and women throughout adulthood with continuities between the 20s and 40s. Adolescent drinking has a modest although important association with adult binge drinking

AIMS: The aim of the study was to determine outcomes in adult life of binge drinking in adolescence in a national birth cohort. DESIGN AND SETTING: Longitudinal birth cohort: 1970 British Birth Cohort Study surveys at 16 years (1986) and 30 years (2000). PARTICIPANTS: A total of 11 622 subjects participated at age 16 years and 11 261 subjects participated at age 30 years. MEASUREMENTS: At the age of 16 years, data on binge drinking (defined as two or more episodes of drinking four or more drinks in a row in the previous 2 weeks) and frequency of habitual drinking in the previous year were collected. Thirty-year outcomes recorded were alcohol dependence/abuse (CAGE questionnaire), regular weekly alcohol consumption (number of units), illicit drug use, psychological morbidity (Malaise Inventory) and educational, vocational and social history. FINDINGS: 17.7% of participants reported binge drinking in the previous 2 weeks at the age of 16 years. Adolescent binge drinking predicted an increased risk of adult alcohol dependence (OR 1.6, 95% CI 1.3 to 2.0), excessive regular consumption (OR 1.7, 95% CI 1.4 to 2.1), illicit drug use (OR 1.4, 95% CI 1.1 to 1.8), psychiatric morbidity (OR 1.4, 95% CI 1.1 to 1.9), homelessness (OR 1.6, 95% CI 1.1 to 2.4), convictions (1.9, 95% CI 1.4 to 2.5), school exclusion (OR 3.9, 95% CI 1.9 to 8.2), lack of qualifications (OR 1.3, 95% CI 1.1 to 1.6), accidents (OR 1.4, 95% CI 1.1 to 1.6) and lower adult social class, after adjustment for adolescent socioeconomic status and adolescent baseline status of the outcome under study. These findings were largely unchanged in models including both adolescent binge drinking and habitual frequent drinking as main effects. CONCLUSIONS: Adolescent binge drinking is a risk behaviour associated with significant later adversity and social exclusion. These associations appear to be distinct from those associated with habitual frequent alcohol use. Binge drinking may contribute to the development of health and social inequalities during the transition from adolescence to adulthood

AIM: To determine whether adolescent alcohol use and/or other adolescent health risk behaviour predisposes to alcohol dependence in young adulthood. DESIGN: Seven-wave cohort study over 6 years. PARTICIPANT: A community sample of almost two thousand individuals followed from ages 14-15 to 20-21 years. OUTCOME MEASURE: Diagnostic and Statistical Manual volume IV (DSM-IV) alcohol dependence in participants aged 20-21 years and drinking three or more times a week. FINDINGS: Approximately 90% of participants consumed alcohol by age 20 years, 4.7% fulfilling DSM-IV alcohol dependence criteria. Alcohol dependence in young adults was preceded by higher persisting teenage rates of frequent drinking [odds ratio (OR) 8.1, 95% confidence interval (CI) 4.2, 16], binge drinking (OR 6.7, 95% CI 3.6, 12), alcohol-related injuries (OR 4.5 95% CI 1.9, 11), intense drinking (OR 4.8, 95% CI 2.6, 8.7), high dose tobacco use (OR 5.5, 95% CI 2.3, 13) and antisocial behaviour (OR 5.9, 95% CI 3.3, 11). After adjustment for other teenage predictors frequent drinking (OR 3.1, 95% CI 1.2, 7.7) and antisocial behaviour (OR 2.4, 95% CI 1.2, 5.1) held persisting independent associations with later alcohol dependence. There were no prospective associations found with emotional disturbance in adolescence. CONCLUSION: Teenage drinking patterns and other health risk behaviours in adolescence predicted alcohol dependence in adulthood. Prevention and early intervention initiatives to reduce longer-term alcohol-related harm therefore need to address the factors, including alcohol supply, that influence teenage consumption and in particular high-risk drinking patterns.

AIMS: To describe the pattern of drinking at age 16 and to relate this to outcomes at 16-21 years and 21-25 years across a number of psychosocial domains. DESIGN: A prospective birth cohort study with annual follow-up until age 16 then at 18, 21 and 25 years. SETTING: Christchurch, New Zealand. PARTICIPANTS: Of 1265 subjects, 953 were interviewed at age 16. MEASUREMENTS: Multiple measures of family background were collected from birth to 16 years. Alcohol consumption was measured in terms of frequency, usual or last quantity drunk and most drunk per occasion. Problems were also recorded. Questions about psychiatric symptoms enabled Diagnostic and Statistical Manual (DSM) criteria to be applied. Detailed reports on educational outcomes, employment, sexual behaviours and offending were collected. FINDINGS: Four latent classes were required to describe drinking at age 16, but these appeared to lie along a single dimension which strongly predicted outcomes at ages 16-21 and 21-25 across all domains (alcohol-related, substance dependence, mental health, education, sexual relationships and offending). After controlling for background and correlates only a small number of outcomes were still related consistently to drinking at age 16 over both periods: most alcohol-related outcomes, the number of sexual partners and the extent of violent offending. CONCLUSIONS: Drinking at age 16 is a clear indicator of future life-course over most domains in late adolescence and early adulthood. Many of these associations are due to other covariates. Outcomes specific to drinking at age 16 are alcohol outcomes, number of sexual partners and violence.

Late adolescence (ie, 16-20 years of age) is a period characterized by escalation of drinking and alcohol use problems for many and by the onset of an alcohol use disorder for some. This heightened period of vulnerability is a joint consequence of the continuity of risk from earlier developmental stages and the unique neurologic, cognitive, and social changes that occur in late adolescence. We review the normative neurologic, cognitive, and social changes that typically occur in late adolescence, and we discuss the evidence for the impact of these transitions on individual drinking trajectories. We also describe evidence linking alcohol abuse in late adolescence with neurologic damage and social impairments, and we discuss whether these are the bases for the association of adolescent drinking with increased risks of mental health, substance abuse, and social problems in adulthood. Finally, we discuss both the challenges and successes in the treatment and prevention of adolescent drinking problems.

Numerous developmental changes occur across levels of personal organization (eg, changes related to puberty, brain and cognitive-affective structures and functions, and family and peer relationships) in the age period of 10 to 15 years. Furthermore, the onset and escalation of alcohol use commonly occur during this period. This article uses both animal and human studies to characterize these multilevel developmental changes. The timing of and variations in developmental changes are related to individual differences in alcohol use. It is proposed that this integrated developmental perspective serve as the foundation for subsequent efforts to prevent and to treat the causes, problems, and consequences of alcohol consumption.

While adolescent alcohol consumption has been asserted to adversely alter brain development, research in human adolescents has not yet provided us with sufficient evidence to support or refute this position. Brain constituents actively developing during adolescence include the prefrontal cortex, limbic system areas, and white matter myelin. These areas serving cognitive, behavioral, and emotional regulation may be particularly vulnerable to adverse alcohol effects. Alternatively, deficits or developmental delays in these structures and their functions may underlie liability to accelerated alcohol use trajectories in adolescence. This review will describe a conceptual framework for considering these relationships and summarize the available studies on the relationships among risk characteristics, alcohol involvement and brain development during this period. The cross-sectional designs and small samples characterizing available studies hamper definitive conclusions. This article will describe some of the opportunities contemporary neuroimaging techniques offer for advancing understanding of adolescent neurodevelopment and alcohol involvement.

LinksAlcohol advertising and alcohol consumption by adolescents.

Saffer H, Dave D.

Department of Economics, Kean University, USA. hsaffer@gc.cuny.edu

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.

Affective decision-making deficits, linked to a dysfunctional ventromedial prefrontal cortex, revealed in 10th grade Chinese adolescent binge drinkers.

The primary aim of this study was to test the hypothesis that adolescent binge drinkers, but not lighter drinkers, would show signs of impairment on tasks of affective decision-making as measured by the Iowa Gambling Test (IGT), when compared to adolescents who never drank. We tested 207 10th grade adolescents in Chengdu City, China, using two versions of the IGT, the original and a variant, in which the reward/punishment contingencies were reversed. This enables one to distinguish among different possibilities of impaired decision-making, such as insensitivity to long-term consequences, or hypersensitivity to reward. Furthermore, we tested working memory capacity using the Self-ordered Pointing Test (SOPT). Paper and pencil questionnaires were used to assess drinking behaviors and school academic performance. Results indicated that relative to never-drinkers, adolescent binge drinkers, but not other (ever, past 30-day) drinkers, showed significantly lower net scores on the original version of the IGT especially in the latter trials. Furthermore, the profiles of behavioral performance from the original and variant versions of the IGT were consistent with a decision-making impairment attributed to hypersensitivity to reward. In addition, working memory and school academic performance revealed no differences between drinkers (at all levels) and never-drinkers. Logistic regression analysis showed that after controlling for demographic variables, working memory, and school academic performance, the IGT significantly predicted binge-drinking. These findings suggest that a "myopia" for future consequences linked to hypersensitivity to reward is a key characteristic of adolescents with binge-drinking behavior, and that underlying neural mechanisms for this "myopia" for future consequences may serve as a predisposing factor that renders some adolescents more susceptible to future addictive behaviors.

Decision making and binge drinking: a longitudinal study.

BACKGROUND: Behavioral decision making, as measured by the Iowa Gambling Task (IGT) is found to be diminished in individuals with substance dependence and other types of disinhibitory psychopathology. However, little is known regarding the relation between heavy alcohol use and decision-making skills in young adults. This study therefore investigated whether binge drinking is related to disadvantageous decision making, as measured by the IGT. We also examined the relation between decision making and impulsivity. METHODS: Latent class growth analysis was used to classify college students into 4 groups (each group n=50, 50% male), based on their binge drinking trajectories over a 2-year time period (precollege through second year of college). Participants were 200 college students, divided in 4 subgroups: (1) low binge drinkers, (2) stable moderate binge drinkers, (3) increasing binge drinkers, and (4) stable high binge drinkers. A measure of decision making, the IGT, impulsivity questionnaires, and multiple indicators of heavy alcohol use were included. RESULTS: The stable high binge-drinking group made less advantageous choices on the IGT than the low binge-drinking group. Impulsivity was not related to decision-making performance. Decision-making performance did not differ by gender, but deck preferences and decision time patterns did differ; women preferred low frequency, high amount punishments to a greater extent than men. CONCLUSIONS: Although disadvantageous decision making is related to binge-drinking patterns in emerging adulthood, this relation is independent of impulsivity. Additionally, the association appears attributable to those who engage in heavy (binge) drinking at an early age, but not to age of onset of drinking in general.

LinksBeyond the "Binge" threshold: heavy drinking patterns and their association with alcohol involvement indices in college students.

Read JP, Beattie M, Chamberlain R, Merrill JE.

Despite its ubiquity, the term "Binge" drinking has been controversial. Among other things, the grouping of drinkers into a single risk category based on a relatively low threshold may not capture adequately the nature of problem drinking behaviors. The present study is an initial examination of the utility of delineating heavy drinkers into three groups; those who typically drink below the traditional "Binge" cutoff (less than 4+/5+ drinks per occasion for women/men), those who met traditional "Binge" drinking criteria, and a higher "Binge" cutoff of 6+/7+ (women, men). We examined differences in drunkenness, drinking frequency, and unique types of alcohol problems. Participants (N=356; 184 women) were regularly drinking college students at a mid-sized U.S. university who completed a battery of self-report measures including a calendar of daily alcohol consumption, and the 8-domain Young Adult Alcohol Consequences Questionnaire (YAACQ). Estimated Blood Alcohol Levels (eBALs) were calculated. We found that the standard 4+/5+ drink "Binge" cutoff distinguishes drinkers across some but not all indices of alcohol involvement. "Binge" drinkers differed from their "Non-Binge" counterparts on eBAL, but for other indicators (drinking frequency, total alcohol consequences), only "Heavy Binge" drinkers differed significantly from "Non-Binge" drinkers. Importantly, "Heavy Binge" drinkers experienced higher levels of those specific consequences associated with more problematic alcohol involvement. Findings suggest that not all "Binge" drinkers drink alike, are equally drunk, or experience similar consequences. As such, there may be utility in distinguishing among heavy drinkers, in order to focus appropriately on those at greatest risk for different types of consequences

LinksA cognitive model of binge drinking: the influence of alcohol expectancies and drinking refusal self-efficacy.

Oei TP, Morawska A.

School of Psychology, University of Queensland, Brisbane 4072, Australia. oei@psy.uq.edu.au

While binge drinking-episodic or irregular consumption of excessive amounts of alcohol-is recognised as a serious problem affecting our youth, to date there has been a lack of psychological theory and thus theoretically driven research into this problem. The current paper develops a cognitive model using the key constructs of alcohol expectancies (AEs) and drinking refusal self-efficacy (DRSE) to explain the acquisition and maintenance of binge drinking. It is suggested that the four combinations of the AE and DRSE can explain the four drinking styles. These are normal/social drinkers, binge drinkers, regular heavy drinkers, and problem drinkers or alcoholics. Since AE and DRSE are cognitive constructs and therefore modifiable, the cognitive model can thus facilitate the design of intervention and prevention strategies for binge drinking.

LinksAcute alcohol effects on cognitive function in social drinkers: their relationship to drinking habits.

Weissenborn R, Duka T.

Laboratory of Experimental Psychology, University of Sussex, Falmer, Brighton BN1 9QG, UK.

RATIONALE: Several studies suggest that cognitive deficits seen in late stages of alcoholism are related to executive function. However, little is known about the acute effects of alcohol on cognitive executive functions. AIMS: The present investigation examined the acute effects of a moderate alcohol dose on tests of planning and spatial working memory as well as on tests of spatial and pattern recognition. The relationship between the acute alcohol effects on performance in these tasks and extreme drinking patterns were also studied. METHODS: Alcohol (0.8 g/kg) or placebo was administered to 95 social drinkers. In the planning task, alcohol decreased the number of solutions with the minimum moves. Alcohol also decreased the thinking time before initiating a response, while it increased the subsequent thinking time in the same task. Under alcohol, participants recognised fewer items in the spatial recognition task; however no effect of alcohol was found in a spatial working memory task and in a pattern recognition task. Among the participants with moderate to heavy use of alcohol, those who were 'bingers' performed worse in the spatial working memory and in the pattern recognition task than 'non-bingers'; no interaction between treatment and drinking pattern was found. CONCLUSION: These data suggest that alcohol given acutely impairs executive-type cognitive functions and that binge drinking may be associated with impaired cognitive function in a working memory and a pattern recognition task.

Binge drinking, cognitive performance and mood in a population of young social drinkers.

Townshend JM, Duka T.

Laboratory of Experimental Psychology, University of Sussex, Falmer, Brighton BN1 9QG.

BACKGROUND: Binge drinking may lead to brain damage and have implications for the development of alcohol dependence. The aims of the present study were to determine individual characteristics as well as to compare mood states and cognitive function between binge and nonbinge drinkers and thus further validate the new tool used to identify these populations among social drinkers. METHODS: The lowest and the highest 33.3% from a database of 245 social drinkers' binge scores derived from the Alcohol Use Questionnaire (AUQ) were used as cutoff points to identify nonbinge drinkers and binge drinkers in a further population of 100 young healthy volunteers. Personality characteristics, expectations of the effects of alcohol and current mood were evaluated. Cognitive performance was tested with a Matching to Sample Visual Search task (MTS) and a Spatial Working Memory task (SWM) both from the CANTAB battery, and a Vigilance task from the Gordon Diagnostic System. RESULTS: The binge drinkers had less positive mood than the nonbinge drinkers. In the MTS choice time on an 8-pattern condition and movement time on an 8- and 4-pattern condition was found to be faster in the binge drinkers compared to nonbinge drinkers. A gender by binge drinking interaction in the SWM and the Gordon Diagnostic System task revealed that female binge drinkers were worse on both these tasks than the female nonbinge drinkers. CONCLUSIONS: These results confirm previous findings in binge drinkers and suggest that in a nondependent alcohol-drinking group, differences can be seen in mood and cognitive performance between those that binge drink and those that do not.
