Up to now, there is no adequate definition of the alcohol hangover. The purpose of the current study was to develop a useful definition, and consensus among those who will use it in scientific publications. A survey was conducted among N=1099 social drinkers who recently had a hangover. They were asked to provide their definition of the alcohol hangover. Text mining and content analysis revealed 3 potential definitions. These were submitted to members of the Alcohol Hangover Research Group, who were asked to give their expert opinion on the proposed definitions. Taking into account their comments and suggestions, the following definition for the alcohol hangover was formulated: \"The alcohol hangover refers to the combination of mental and physical symptoms, experienced the day after a single episode of heavy drinking, starting when blood alcohol concentration approaches zero.\"

The Dutch College of General Practitioners\' practice guideline \"Problem drinking\" contains recommendations for the (early) recognition, diagnosis and treatment of problem drinking and includes recommendations for young people and the management of acute alcohol intoxication. In daily practice problems with alcohol manifest themselves mainly as indirect signals and aspecific symptoms. The practice guideline recommends asking about alcohol use in every case where symptoms cannot be directly explained. General practitioners are usually able treat patients with a drinking problem themselves. Short-term interventions by the general practitioner and practice nurse are effective in the reduction of alcohol use. \'E-mental health\' is an aid that can be used in the diagnosis and treatment of problem alcohol use.

OBJECTIVE: Undergraduate students frequently exceed guideline limits for alcohol intake in a single session and are highly susceptible to associated health, social, and economic problems. Psychological theory suggests that interventions aimed at reducing alcohol consumption should target both motivational and volitional phases of action to be effective. This study reports an integrated theory-based intervention aimed at reducing undergraduates\' alcohol consumption in excess of guideline limits.
METHODS: The study adopted a 2 (motivation: mental simulation vs. no mental simulation) × 2 (volitional: implementation intention vs. no implementation intention) randomized controlled design presented in an online format.
METHODS: Undergraduate students (N= 238; females, n= 133, M age = 20.11, SD= 2.09; males, n= 105, M age = 20.38, SD= 1.35) completed baseline psychological measures and self-reported alcohol consumption as units consumed and heavy episodic drinking occasions followed by the intervention manipulation (if any). One month later participants completed follow-up measures of the psychological variables and alcohol consumption.
RESULTS:  Significant reductions in alcohol consumption were observed at follow-up. Participants receiving a mental simulation intervention reported significantly fewer units of alcohol consumed and heavy episodic drinking occasions. Among participants with high baseline alcohol consumption, participants in the combined mental simulation and implementation intention intervention group consumed significantly fewer units than other groups.
CONCLUSIONS: Results support the use of these theory-based strategies to reduce alcohol drinking in excess of guideline limits among undergraduates. There was preliminary support for the interaction between the two strategies among heavier drinkers. Targeting both motivational and implemental phases of action poses a high probability for success in changing alcohol-related behaviour in this population.

The history of drink driving and legislative responses to it remain virtual terra incognita. This contribution traces developments in Britain between 1945 and the aftermath of the Road Safety Act in 1967. The first section focuses on the formation of an extra-parliamentary pressure group in the 1950s. This is complemented by an interpretation of the impact of the government-backed Drew Report (1959), and the ways in which Drew\'s research was rhetorically and creatively deployed by Graham Page, leading spokesman for the Pedestrians\' Association and Ernest Marples, the Conservative Minister of Transport. The final section interrogates key debates leading up to the introduction of the breathalyser. The article concludes that belated introduction of road safety legislation in Britain in the 1960s revealed a high degree of cross-party consensus. Only senior officials at the Home Office, and to a lesser extent, at the Ministry of Transport, repeatedly threatened to delay reform.

Alcohol-induced hangover, defined by a series of symptoms, is the most commonly reported consequence of excessive alcohol consumption. Alcohol hangovers contribute to workplace absenteeism, impaired job performance, reduced productivity, poor academic achievement, and may compromise potentially dangerous daily activities such as driving a car or operating heavy machinery. These socioeconomic consequences and health risks of alcohol hangover are much higher when compared to various common diseases and other health risk factors. Nevertheless, unlike alcohol intoxication the hangover has received very little scientific attention and studies have often yielded inconclusive results. Systematic research is important to increase our knowledge on alcohol hangover and its consequences. This consensus paper of the Alcohol Hangover Research Group discusses methodological issues that should be taken into account when performing future alcohol hangover research. Future research should aim to (1) further determine the pathology of alcohol hangover, (2) examine the role of genetics, (3) determine the economic costs of alcohol hangover, (4) examine sex and age differences, (5) develop common research tools and methodologies to study hangover effects, (6) focus on factor that aggravate hangover severity (e.g., congeners), and (7) develop effective hangover remedies.

BACKGROUND: With surveys suggesting that exceeding guidelines for \'sensible\' alcohol intake is commonplace, the health and social impact of modifying intake on a population level is potentially considerable. If public health interventions are to be successfully implemented, it is first important to identify correlates of such behaviours, including socioeconomic disadvantage. This was the aim of the present study.
METHODS: Population-representative cohort study of 576 men from the West of Scotland. Data on life course socioeconomic position were collected in 1988 (at around 55 years of age). Alcohol consumption patterns (detailed seven day recall) and problem drinking (CAGE questionnaire) were ascertained in 1990/2 (at around 59 years of age). A relative index of inequality was computed to explore the comparative strength of different indicators of social circumstances from different periods of the life course.
RESULTS: Socioeconomic adversity in both early life and in adulthood was related to an increased risk of exceeding the weekly and daily alcohol guidelines, with adult indicators of socioeconomic position revealing the strongest associations. Of these, material indicators of socioeconomic deprivation in adulthood - car ownership, housing tenure - were marginally more strongly related to heavy alcohol intake and problem drinking than education, income and occupational social class. A substantial proportion of the influence of early life deprivation on alcohol intake was mediated via adult socioeconomic position. Similar results were apparent when problem drinking was the outcome of interest.
CONCLUSIONS: In men in this cohort, exposure to disadvantaged social circumstances across the lifecourse, but particularly in adulthood, is associated with detrimental patterns of alcohol consumption and problem drinking in late middle age.

OBJECTIVE: This study evaluated gender-specific ethanol dosing protocols that were designed to result in one of two peak breath alcohol concentrations (BrACs)--0.07 or 0.10 g/2101. Inter- and intrasubject variability in BrAC were assessed and several possible methods for reducing variability in BrAC were evaluated.
METHODS: Subjects (16 women, 16 men, ages 21-30 years) were studied after low (women 0.49 g/kg, men 0.53 g/kg consumed over 10 minutes) and high (women 0.81 g/kg, men 0.89 g/kg consumed over 20 minutes) ethanol doses, consumed following a 4-hour fast. All subjects were regular drinkers.
RESULTS: Mean (+/-SD) peak BrACs actually achieved were 0.069+/-0.011 g/2101 after the low dose, and 0.105+/-0.014 g/2101 after the high dose. Mean values for peak BrAC, time to peak BrAC and area under the curve were not statistically significantly different between genders at either dose. BrACs varied by as much as twofold between subjects after equivalent gender and body weight adjusted doses. There was some reproducibility of ethanol pharmacokinetic parameters over dose and time in men, but not in women.
CONCLUSIONS: The doses used resulted in equivalent mean ethanol exposures for women and men at each dose, with mean peak BrACs that closely approached the targets, but there was substantial inter- and intrasubject variability in ethanol pharmacokinetics.
