Drinking behaviours and blood alcohol concentration in four European drinking environments: a cross-sectional study.

BACKGROUND: Reducing harm in drinking environments is a growing priority for European alcohol policy yet few studies have explored nightlife drinking behaviours. This study examines alcohol consumption and blood alcohol concentration (BAC) in drinking environments in four European cities. METHODS: A short questionnaire was implemented among 838 drinkers aged 16-35 in drinking environments in four European cities, in the Netherlands, Slovenia, Spain and the UK. Questions included self-reported alcohol use before interview and expected consumption over the remainder of the night. Breathalyser tests were used to measured breath alcohol concentration (converted to BAC) at interview. RESULTS: Most participants in the Dutch (56.2%), Spanish (59.6%) and British (61.4%) samples had preloaded (cf Slovenia 34.8%). In those drinking < 3 h at interview, there were no differences in BAC by gender or nationality. In UK participants, BAC increased significantly in those who had been drinking longer, reaching 0.13% (median) in females and 0.17% in males drinking > 5 h. In other nationalities, BAC increases were less pronounced or absent. High BAC (> 0.08%) was associated with being male, aged > 19, British and having consumed spirits. In all cities most participants intended to drink enough alcohol to constitute binge drinking. CONCLUSIONS: Different models of drinking behaviour are seen in different nightlife settings. Here, the UK sample was typified by continued increases in inebriation compared with steady, more moderate intoxication elsewhere. With the former being associated with higher health risks, European alcohol policy must work to deter this form of nightlife.

Alcohol and drug prevention in nightlife settings: a review of experimental studies.

This study examines the evidence regarding the effectiveness of interventions aimed at the prevention of harmful alcohol and drug use in nightlife settings. A literature search was conducted in 2009. Of 161 studies, 17 experimental studies were included in the review, 15 alcohol-related and two drug-related studies. The results show that preventive substance abuse interventions in nightlife settings can effectively reduce high-risk alcohol consumption, alcohol-related injury, violent crimes, access to alcohol by underage youth, and alcohol service to intoxicated people. A combination of approaches such as enforcement activities seem to be facilitating factors. However, results should be considered cautiously as more gold standard (cost-) effectiveness research is required, in particular directed at drug prevention and educational interventions in nightlife settings.

Computer-based programmes for the prevention and management of illicit recreational drug use: a systematic review.

The last few decades have seen increasing use of computer-based programmes to address illicit recreational drug use but knowledge about their effectiveness is limited. We conducted a systematic review to examine evidence on these programmes. Eight electronic databases were searched to identify primary research studies evaluating computer-based programmes to prevent or reduce use of illicit recreational drugs. From an initial 3413 extracted studies, 10 were identified for inclusion, covering a range of intervention types, target groups and settings. Universal drug prevention programmes were effective in reducing the frequency of recreational drug use in the mid-term (<12 months), but not immediately post intervention. Programmes targeting recreational drug users showed more inconsistent results but were generally effective in reducing use of drugs both immediately and in the mid-term. Computer-based programmes have the potential for use in addressing recreational drug use when targeted both universally and at illicit drug users, at least in the mid-term. However, longer term evaluations are needed to better understand the duration of effects. Given the benefits that computer-based programmes can have over traditional delivery methods, research is needed to better understand the value of human contact in health interventions and help inform whether, and how much, professional contact should be involved in computer-based programmes.

Drunk and disorganised: relationships between bar characteristics and customer intoxication in European drinking environments.

Preventing alcohol-related harm in drinking environments is a growing international priority. Factors relating to the physical, social and staffing environments in bars can contribute to increased alcohol consumption and harm. Understanding the relationships between such factors and intoxication in European drinking environments is critical to developing appropriate interventions. We undertook a quantitative observational study in 60 bars in four European cities, in The Netherlands, Slovenia, Spain and the UK (n = 237 observational visits). Using a structured observational schedule, researchers recorded characteristics of the bar environment and rated customer intoxication levels. All physical bar characteristics showed associations with intoxication before interactions between them were controlled for. Hierarchical modelling found significant independent associations between intoxication and use of plastic glassware, promotion of non-alcoholic drinks (often energy drinks), permissive environments, poor washroom facilities, the presence of a dance floor, customer sexual activity/competitiveness and later observational time. Findings suggest that prevention efforts should focus on raising and enforcing managerial standards in bars. While harm reduction measures such as plastic glassware are often promoted for high risk bars, such measures are inadequate to address public health concerns and insufficient to demonstrate social responsibility.
