Harms from other people's drinking: an international survey of their occurrence, impacts on feeling safe and legislation relating to their control

Serving Alcohol to an "Obviously Intoxicated" Patron

OBJECTIVE

Alcohol overservice at on-premises establishments is associated with driving while intoxicated, violence, and other harms. This study examined rates of alcohol overservice and service refusal among licensed on-premises establishments in northern California and characteristics of establishments, servers, and pseudo-patrons (PPs) that may be associated with service refusal.

METHOD

In 2022, 300 licensed on-premises establishments were sampled in nine counties representing the San Francisco Bay Area. From July 2022 to January 2023, PP and observer teams visited each establishment, and PPs attempted to buy alcohol while displaying obvious signs of intoxication. The outcome of each purchase attempt; characteristics of establishments, servers, and PPs; and month, day, and time were recorded. Descriptive and regression analyses were conducted to address study objectives.

RESULTS

Twenty-one percent of the establishments refused alcohol service to PPs. No establishment or server characteristics were significantly associated with service refusal in logistic regression analysis, nor were month, day, or time. However, service refusal was significantly more likely among female PPs (odds ratio = 3.71, 95% CI [1.67, 8.24], p < .01) and PPs displaying obvious or very obvious signs of intoxication (odds ratio = 9.28, 95% CI [1.99, 43.40], p < .01). There was no significant interaction effect of PP × Server Gender on the likelihood of service refusal.

CONCLUSIONS

This study indicates that alcohol overservice to obviously intoxicated patrons remains common at licensed on-premises establishments. Mandatory responsible beverage service training of servers and enforcement of alcohol overservice laws are needed to reduce overservice and related harms.

Regrets, I've Had a Few: Exploring Factors Associated with Getting Drunk and Regret in an International Study of People Who Drink Alcohol

BACKGROUND

Excessive alcohol consumption is often followed by feelings of regret. This study aimed to explore country differences in experiences of drunkenness and regrets and predictors of experiencing a greater number of regrettable drinking occasions.

METHODS

This study draws on a sample of 82,821 respondents from 31 countries who completed the 2020 Global Drug Survey. Respondents were asked to report how many times in the last year they had been drunk, how many of those times they felt regret afterwards and to complete a range of sociodemographic measures.

RESULTS

In the last 12 months, the median times drunk was 6 and the median number of regretted occasions was 2. There was an inverse relationship between times drunk and regret. Respondents who got drunk more often regretted it a smaller percentage of the time than those who got drunk less often. Respondents from Argentina and Colombia regretted being drunk the most and Denmark the least. Being younger, in higher AUDIT categories were associated with more times drunk. Being a woman, having mental health conditions were associated with more regretted occasions.Discussion and conclusions: Country variations may reflect relative acceptability of being drunk. Those who drink more, per occasion, may become accustomed to the consequences and feel fewer regrets. Interventions promoting reduced alcohol consumption may benefit from encouraging people to consider their future regret following a drinking occasion but should account for lower levels of regret in those who get drunk more often.

Combined use of cocaine and alcohol: A violent cocktail? A systematic review

It is generally believed that the use of alcohol and cocaine alone and especially in combination elicits aggression and violent behaviour. Though there is overwhelming proof that heavy alcohol use is associated with violence, this is not the case for cocaine. Still, in the popular press and by spokesmen of the police, cocaine use is seen as a cause of violent incidents. In the current systematic review, available data from human studies on the relation between cocaine and violent behaviour is presented. In particular, we present scientific data on the acute induction of violence by cocaine alone, as well as, that by the combination of cocaine and alcohol known to be frequently used simultaneously. RESULTS: show that there is only weak scientific evidence for the acute induction of violent behaviour by cocaine, either when used alone or in combination with alcohol. Based on these data we were also able to refute misconceptions about the relation between cocaine and violence published in the popular press and governmental reports, because it appeared that there was hardly any empirical support for this widely shared opinion. Probably, contextual factors, including cocaine use disorder and personality disorder, may better explain the assumed association between cocaine and violence.

Prevalence and self-rated health and depression of family members affected by addictive disorders: results of a nation-wide cross-sectional study

AIMS

To estimate the prevalence of family members affected by addictive disorders (FMA) with regard to various types of addictive disorders, and self-rated health and depression in the general population.

DESIGN

Cross-sectional general population survey.

SETTING

The German Health Update study (GEDA) 2014/2015, a nationally representative panel of German residents aged 15 years or older.

PARTICIPANTS

A total of 24 824 residents aged 15 years or older.

MEASUREMENTS

Participants were asked if they had a family member with current or past addictive disorder, the type of addiction and the relationship status. In addition, self-rated health and depression were assessed using standardized questionnaires.

FINDINGS

Of the respondents, 9.5% [95% confidence interval (CI) = 9.0-10.0] reported being affected by a current addictive disorder of a relative (cFMA), with a further 4.5% (95% CI = 4.2-4.9) reported having been affected by the addictive disorders of a relative in the past but not within the last 12 months (pFMA). Most FMAs reported having been affected by disorders due to alcohol, followed by cannabis and other drugs. Compared with life-time non-FMAs, FMAs reported significantly (P < 0.001) higher odds ratios for depression (cFM = 2.437; 95% CI = 2.082-2.853; pFMA = 1.850; 95% CI = 1.519-2.253) and ill-health (cFMA = 1.574; 95% CI = 1.374-1.805; pFMA = 1.297; 95% CI = 1.082-1.555).

CONCLUSIONS

In Germany, family members affected by addictive disorder are a substantial group within the general population. This group is characterized by ill-health and has not yet been adequately addressed by the addiction treatment system.

Gender and sexual identity and harms from others' drinking among U.S. college students: Results from a multi-campus survey

BACKGROUND

College is a critical life stage for alcohol-related harms to others (AHTOs), gender, and sexual identity. We tested associations between inclusively-defined gender and sexual identities (separately) and AHTOs among college students.

METHODS

The Healthy Minds Study (n = 8,308) provided data about three AHTOs: (1) babysitting a drunk student, (2) alcohol-related unwanted sexual advance, and (3) alcohol-related sexual assault. Independent variables included gender and sexual identity.

RESULTS

One in four students (25.5%) reported babysitting, 6.2% reported unwanted advances, and 1.2% reported sexual assaults. Compared to cisgender males, cisgender females had higher odds of reporting babysitting (aOR = 1.36, p < 0.001) and unwanted advances (aOR = 2.59, p < 0.001); trans masculine students had higher odds of reporting sexual assaults (aOR = 4.49, p = 0.04).

CONCLUSIONS

AHTOs are prevalent on college campuses, and cisgender female and trans masculine students have higher odds of experiencing them. Alcohol interventions may protect cisgender female and gender minority students from the drinkers around them.

Global comparisons of responses to alcohol health information labels: A cross sectional study of people who drink alcohol from 29 countries

AIMS

The aim of this paper was to explore responses to alcohol health information labels from a cross sectional survey of people who drink alcohol from 29 countries.

DESIGN

This paper draws on findings from the Global Drug Survey (GDS) - an annual cross sectional online survey.

PARTICIPANTS

75,969 (64.3% male) respondents from 29 countries were included in the study.

MEASURES

Respondents were shown seven health information labels (topics were heart disease, liver, cancer, calories, violence, taking two days off and myth of benefits of moderate drinking). They were asked if the information was new, believable, personally relevant, and if it would change their drinking. A multivariate multilevel Bayesian logistic regression model was used to estimate predicted probabilities for newness, believability, relevance and if messages would change drinking behaviour by country and information label.

FINDINGS

Predicted probabilities showed substantial variability in responses across countries. Respondents from Colombia, Brazil and Mexico were more likely to consider drinking less as well as have lower levels of previous awareness. Those from Denmark and Switzerland were not as likely to say the labels would make them consider drinking less. The cancer message was consistently the newest and most likely to make people consider drinking less across countries.

CONCLUSIONS

Country differences in responses to messages can be used to create targeted harm reduction measures as well as inform what should be on labels. The provision of such health information on alcohol product labels may play a role in raising awareness of the risk of drinking. Global comparisons of responses to alcohol health information labels: a cross sectional study of people who drink alcohol from 29 countries.

Effects of multi-component programmes in preventing sales of alcohol to intoxicated patrons in nightlife settings in the United Kingdom

•

Alcohol service to intoxicated patrons in nightlife settings is common.

•

Multi-component interventions can prevent alcohol over-service.

•

Effects are stronger for interventions including enhanced law enforcement.

Introduction

Alcohol service to intoxicated patrons is common across nightlife settings and preventing such sales is a key priority globally. In England and Wales, three multi-component programmes have been implemented including: (1) community mobilisation, responsible beverage server (RBS) training and routine law enforcement; (2) community mobilisation and enhanced law enforcement; and, (3) community mobilisation, RBS training and enhanced law enforcement. This study estimates the association between sales of alcohol to pseudo-intoxicated patrons and implementation of three multi-component interventions in four nightlife settings.

Methods

Alcohol test purchases by pseudo-intoxicated actors were implemented at pre (n = 206) and post-intervention (n = 224). Actors/observers recorded venue and test purchase characteristics. Logistic regression assessed service refusal by intervention type, adjusting for venue/test purchase characteristics.

Results

Pre-intervention, 20.9% of sales were refused. Post-intervention, 42.1%, 68.8% and 74.0% of sales were refused in areas with intervention 1, 2, and 3 respectively. In adjusted analyses, compared to pre-intervention, the odds of service refusal were higher for all interventions, with the highest odds when the intervention included enhanced law enforcement (adjusted odds ratios, interventions 1, 2, 3: 2.6, 7.1, 14.4; p < 0.01). Service refusal was higher if the test purchase was implemented on a Saturday/Sunday night; and lower if implemented in a nightclub or if age verification was requested at the bar.

Conclusion

Community-based multi-component interventions were associated with significant increases in service refusal to pseudo-intoxicated actors in nightlife settings in England and Wales. Effects were stronger for interventions including enhanced law enforcement, and particularly if all intervention components were implemented.

Effectiveness of a digital intervention versus alcohol information for online help-seekers in Sweden: a randomised controlled trial

BACKGROUND

The ubiquity of Internet connectivity, and widespread unmet needs, requires investigations of digital interventions for people seeking help with their drinking. The objective of this study was to test the effectiveness of a digital alcohol intervention compared to existing online resources for help seekers.

METHODS

This parallel randomised controlled trial included 2129 risky drinkers with access to a mobile phone and aged 18 years or older. Randomised sub-studies investigated consent procedures and control group design. Simple computerised randomisation was used. Participants were aware of allocation after randomisation; research personnel were not. The digital intervention was designed around weekly monitoring of alcohol consumption followed by feedback and tools for behaviour change. Primary outcomes were total weekly consumption (TWC) and frequency of heavy episodic drinking (HED), measured 2 and 4 months post-randomisation.

RESULTS

Between 25/04/2019 and 26/11/2020, 2129 participants were randomised (intervention: 1063, control: 1066). Negative binomial regression was used to contrast groups, with both Bayesian and maximum likelihood inference. The posterior median incidence rate ratio (IRR) of TWC was 0.89 (95% CI = 0.81;0.99, 98.2% probability of effect, P-value = 0.033) at 2 months among 1557 participants and 0.77 (95% CI = 0.69;0.86, > 99.9% probability of effect, P-value < 0.001) at 4 months among 1429 participants. For HED, the IRR was 0.83 (95% CI = 0.75;0.93, > 99.9% probability of effect, P-value = 0.0009) at 2 months among 1548 participants and 0.71 (95% CI = 0.63;0.79, probability of effect > 99.9%, P-value < 0.0001) at 4 months among 1424 participants. Analyses with imputed data were not markedly different.

CONCLUSIONS

A digital alcohol intervention produced self-reported behaviour change among online help seekers in the general population. The internal and external validity of this trial is strong, subject to carefully considered study limitations arguably inherent to trials of this nature. Limitations include higher than anticipated attrition to follow-up and lack of blinding.

TRIAL REGISTRATION

The trial was prospectively registered ( ISRCTN48317451 ).

Selling World Health Organization's Alcohol “Best Buys” and Other Recommended Interventions in an Urban Chinese Population: Public Acceptability of Alcohol Harms Reduction Strategies in Hong Kong

Background

To counter the harms caused by alcohol use, the World Health Organization (WHO) outlined a series of evidence-based recommendations, including the highly cost-effective “Best Buys” recommendations. While many Western countries have been actively introducing alcohol harms reduction strategies, it is unclear whether these cost-effective policies would be publicly acceptable in Asian regions with traditionally low alcohol consumption. This study examines the public acceptability of WHO-recommended alcohol harms reduction strategies in an Asian city with few extant alcohol regulations.

Methods

A cross-sectional telephone survey of Hong Kong Chinese residents aged 18–74 (n = 4,000) was conducted from January to August 2018. Respondents were asked about their perceptions of various WHO-recommended strategies and consequences of their implementation. After reducing the strategies into several policy categories by principal component analysis, multivariable linear regression was performed to identify factors associated with endorsement of the various policies.

Results

Among the “Best Buys”, introduction of moderate beer/wine taxes (68.7%) and shortened alcohol retail hours (51.9%) were the most supported while bans on event sponsorships (19.5%) and public drinking events (17.7%) were the least popular. Strategies targeting young drinkers were particularly highly supported. Males, younger adults, Non-abstainers, and those who believed in drinking's social benefits were less likely to endorse stringent control measures (p < 0.05). Adults with higher household income were less supportive, partially due to concerns about infringements on local economy, lifestyles, and economic freedom. Women and older people were generally more supportive, partially because they perceived these policies would lower alcohol-related harms.

Conclusion

In order to reduce barriers to implementing WHO-recommended strategies in the region, it is imperative to increase awareness of alcohol-related harms and to strengthen beliefs in the effectiveness of these countermeasures, especially among men, young adults, and drinkers.

Care of women and girls after sexual assault in Geneva: A descriptive study between 2005 and 2014

BACKGROUND AND PURPOSE

We aimed to examine epidemiological data and identify risk factors for sexual assault. This study included women seeking care at the Geneva University Hospitals emergency obstetrics and gynaecological unit.

METHOD

Retrospective, sociodemographic, and clinical data were collected from the medical reports.

RESULTS

We reviewed 836 medical charts and registered 92.8 women and girls per year who consulted the emergency department after sexual assault. The average age was 26 (±12) years, with a median of 23 years. Body lesions were reported in 525 patients (63%) and genital traumatic lesions were reported in 230 (28%) patients. Sexual assault by a stranger was reported in 436 cases (52%). Thirty percent of patients knew their aggressor. Aggressions were predominantly committed on the weekend, accounting for 367 cases (46%), with nearly two-thirds (65%, n = 474) occurring between 10 pm and 6 am. In total, 399 (48%) patients who were sexually assaulted reported having consumed alcohol and 102 (12%) reported having taken drugs prior to the aggression; 80 (10%) patients had consumed both and 286 (34%) had amnesia. Half of the sample sought and received medical care within 24 h from the time the aggression took place.

CONCLUSION

Sexual assault risk factors in our study population in Geneva included use of drugs and alcohol, with amnesia. Future prevention and education interventions should target these areas.

STOP-sexual violence: evaluation of a community-based nightlife worker awareness raising bystander training programme

BACKGROUND

Preventing sexual violence in nightlife environments is a pervasive issue across many countries. This study explored the associated impact of a nightlife worker sexual violence awareness raising/bystander training programme (STOP-SV) on trainees' sexual violence myth acceptance and readiness and confidence to intervene.

METHODS

: Pre- and post-test (n = 118), and 3-month follow-up (n = 38) trainee surveys were implemented across three countries (Czech Republic, Portugal and Spain). Paired-sample tests examined changes across time-periods in participants' myth acceptance (e.g. unwanted sexual advances are a normal part of a night out), and readiness and confidence to intervene. Multi-nominal regression was used to examine the relationship between the change in pre-to-post-training scores and trainee characteristics.

RESULTS

Compared to pre-training, post-training participants were significantly (P < 0.01) less likely to agree with sexual violence myths, and more likely to be ready and confident to intervene. In bi-variate and multi-variate analyses, we found no significant associations between the change in pre-to-post-training scores and trainee characteristics. Analyses of the small follow-up sub-sample illustrated some positive changes at the post-training and follow-up time-periods (i.e. reduction in sexual violence myth acceptance).

CONCLUSION

This exploratory study suggests that the STOP-SV training programme was associated with a decrease in trainees' acceptance of sexual violence myths, and an increase in their readiness and confidence to intervene. Our findings support the case for further implementation and evaluation of awareness raising/bystander programmes for nightlife workers that aim to prevent and respond to sexual violence.

Alcohol Use and Sexual and Physical Assault Victimization Among University Students: Three Years of Follow-Up

The aim of this study was to determine the incidence of sexual and physical assault among university students and its association with alcohol use. The research is part of a wider cohort study (Spit for ScienceTM) at a large public university in the United States. The follow-up data include the first two cohorts (2011, 2012; n = 5,170). The dependent variables were victim of sexual assault and victim of physical assault. The independent variables were alcohol dependence and abuse according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.), cannabis use, residence, ethnicity, sexual orientation, and previous experience of sexual assault and/or physical assault. We used multilevel logistic regression for repeated measures. All data were analyzed using generalized linear mixed models. Incidence rates of sexual and physical assault (per 100 students a year) were 15.1 and 27.6 among nonabusers/dependents versus 36.4 and 56.7 among alcohol-dependent females at the first year, and 2.8 and 4.7 versus 7.7 and 23.1 at the third year; while in males, incident rates were 6.0 and 3.1 versus 18.5 and 66.6, and 2.3 and 7.4 versus 18.9 and 15.1, respectively. Our results show that alcohol abuse and dependence constitute risk factors to be victim of sexual assault in males (odds ratio [OR] = 2.21 and OR = 2.73) and alcohol dependence in females (OR = 2.16). Similarly, alcohol abuse and dependence are risk factors to physical assault among both males (OR = 1.52 and OR = 2.03) and females (OR = 1.70 and OR = 2.88). Ethnicity, sexual orientation, and whether the individual had been victimized in the past were associated with sexual assault. Regarding physical assault, cannabis use and past victimization are also risk factors. Our study has shown that assault victimization is strongly related to alcohol abuse and dependence diagnoses in both genders. Ethnicity and sexual orientation are also associated to both assaults. Our results show that incidence rates of both types of assaults were clearly higher in the first 6 months of university, probably explained by the novel and potentially risky environment.

The Influence of Alcohol Consumption on Fighting, Shoplifting and Vandalism in Young Adults

Experimental studies support the conventional belief that people behave more aggressively whilst under the influence of alcohol. To examine how these experimental findings manifest in real life situations, this study uses a method for estimating evidence for causality with observational data-'situational decomposition' to examine the association between alcohol consumption and crime in young adults from the Avon Longitudinal Study of Parents and Children. Self-report questionnaires were completed at age 24 years to assess typical alcohol consumption and frequency, participation in fighting, shoplifting and vandalism in the previous year, and whether these crimes were committed under the influence of alcohol. Situational decomposition compares the strength of two associations, (1) the total association between alcohol consumption and crime (sober or intoxicated) versus (2) the association between alcohol consumption and crime committed while sober. There was an association between typical alcohol consumption and total crime for fighting [OR (95% CI): 1.47 (1.29, 1.67)], shoplifting [OR (95% CI): 1.25 (1.12, 1.40)], and vandalism [OR (95% CI): 1.33 (1.12, 1.57)]. The associations for both fighting and shoplifting had a small causal component (with the association for sober crime slightly smaller than the association for total crime). However, the association for vandalism had a larger causal component.

Association between Exposure to Alcohol's Harm to Others and Health-Related Quality of Life in Korean Adults: A Nationwide Population-Based Study

This study aimed to investigate the association between exposure to alcohol's harm to others (AHTO) and health-related quality of life HRQoL using a nationally representative sample. Data from 2016-2018 of 17,346 South Korean individuals aged ≥19 years were obtained from the Korea National Health and Nutrition Examination Survey. HRQoL was evaluated using the European Quality of Life-5 Dimensions (EQ-5D) index. A significant positive association was found between exposure to AHTO and lower EQ-5D scores (p = 0.022). In the final model of multiple regression analysis, participants' HRQoL decreased by 0.932 points when exposed to AHTO (R² = 36.5%, p < 0.001). In addition, the exposure to AHTO group had significantly higher odds ratios (OR) for pain/discomfort (OR: 1.42, 95% CI: 1.15-1.75) and anxiety/depression (OR: 1.55, 95% CI: 1.68-2.80) compared to the non-AHTO group. Further studies are required for intervention when exposed to reduce the pain/discomfort and anxiety/depression in AHTO victims as well as to reduce the incidence of AHTO.

Association between state-level alcohol availability and taxation policies on the prevalence of alcohol-related harms to persons other than the drinker in the USA, 2000-2015

INTRODUCTION AND AIMS

Alcohol-related harms to others (AHTO) are consequences of alcohol use borne by persons other than the drinker. This study assessed whether the odds of experiencing AHTO are associated with alcohol availability and taxation policies.

DESIGN AND METHODS

This study pooled data from four waves of the National Alcohol Survey (n = 20656 adults). We measured past-year AHTO exposure using three binary variables: physical (pushed/hit/assaulted or property damage by someone who had been drinking), family or financial (family/marital problems or financial harms by someone who had been drinking) and driving AHTO (riding in a vehicle with a drink-driver or being in a drink-driving crash). Policies included bar and off-premise alcohol outlet density (separately), alcohol retail hours, beer and spirits taxes (separately) and monopoly on retail/wholesale alcohol purchases.

RESULTS

Monopolies were associated with 41.2% lower odds of physical harms [adjusted odds ratio (aOR) = 0.59, 95% confidence interval (CI) 0.45, 0.77, q < 0.001 correcting for multiple analyses], and a 10% increase in bar density was associated with a 1.2% increase in odds of driving-related harms ( e ^{ln(1.1) * β} =1.01, 95% CI 1.00, 1.02, q = 0.03). Among men, beer taxes were associated with lower odds of physical harms ( e^{ln(1.1) * β} =0.93, 95% CI 0.88, 0.98 q = 0.03) and monopolies were associated with lower odds of physical (aOR = 0.45, 95% CI 0.35, 0.59, q < 0.001) and driving harms (aOR = 0.66, 95% CI 1.00, 1.02, q = 0.03).

DISCUSSION AND CONCLUSIONS

Monopolies, taxes and outlet density are associated with odds of some AHTO. Future longitudinal research should test whether physical availability and taxation policies may be protective for bystanders as well as drinkers.

Frightening or Foolish? Gendered Perceptions of Public Intoxication Among Youths and Adults in Norway and Finland

Background: What people define as acceptable alcohol use may differ between social situations and depend upon on who is drinking as well as who is evaluating the situation. Objective: The aim of the study was to explore how Norwegian and Finnish youth and adults perceived the acceptability of situations involving public intoxication and how gender and alcohol's harm to others were made relevant in their reflections. Methods: We conducted eight focus groups among adolescents (N = 44) and eight among adults (N = 38), using photos and stories of drinking situations as stimuli for the discussions. Results: Youths' and adults' perceptions of public intoxication were characterized by ambivalence: negative evaluations were often nuanced and negotiated while positive evaluations typically were followed up with reservations. To some extent, their evaluations depended upon the gender and age of the drinker. Although a norm of gender equality was emphasized, women were typically criticized for their looks and for foolish behavior when drunk, while drunk men were often perceived as frightening. Age was a prominent dimension in evaluations of the acceptability of women's alcohol use, while it was seldom mentioned when discussing intoxicated men. Youths seemed to have somewhat more restrictive attitudes towards public intoxication than adults, reflecting perhaps how they related to the situations with more general conceptions of drinking and harms from drinking, picked up from public debate or from school. Conclusion: Perceptions of alcohol's harm to others were clearly gendered, in that intoxicated men were seen as frightening while women were seen as foolish.

Alcohol's harms to others in Wales, United Kingdom: Nature, magnitude and associations with mental well-being

Aim

To explore the nature and magnitude of alcohol's harms to others (AHTOs), and associations with mental well-being.

Methods

Cross-sectional survey implemented amongst 891 randomly selected Welsh residents (aged 18+ years), via computer assisted telephone interviews. Questions established past 12-month experience of nine direct harms resulting from another person's alcohol consumption (e.g. violence) and five linked outcomes (e.g. concern for a child). The source (e.g. partner/stranger) and frequency of the AHTO were collected, and respondents' socio-demographics, drinking behaviours and mental well-being status.

Results

During the past 12 months, 43.5% of respondents had experienced at least one direct harm (45.5% at least one direct harm/linked outcome). In demographically adjusted analyses, the odds of experiencing any direct harm decreased sequentially as age group increased (Adjusted Odds Ratio [AORs]: 1.9 [age 65–74 years] - 4.2 [age 18–34 years]), and was higher amongst binge drinkers (AOR, 1.5, p < 0.05). Associations between age group and suffering the direct harms anxiety, disrupted sleep, feeling threatened, property damage and emotional neglect were found. Experience of feeling threatened was lower amongst females (AOR 0.6, p < 0.05). In demographically adjusted analyses, low mental well-being was higher amongst those who had suffered alcohol-related financial issues (AOR 2.2, p < 0.001), emotional neglect (AOR 2.3, p < 0.01) and property damage (AOR 2.2, p < 0.05).

Conclusion

AHTOs place a large, although unequal burden on adults in Wales. Individuals' drinking patterns are associated with experience of AHTOs. Critically, experience of some harms is associated with low mental well-being.

•

The harms from alcohol extend from the drinker to those around them (i.e. alcohol's harms to others [AHTOs]).

•

AHTOs place a large, although unequal burden on the Welsh adult population, with young people and binge drinkers most at-risk.

•

Experience of some AHTOs is associated with low mental well-being.

•

AHTOs should be a consideration in the development, targeting and evaluation of alcohol policy and prevention activity.

My own personal hell: approaching and exceeding thresholds of too much alcohol

Objectives: Government guidelines aim to promote sensible alcohol consumption but such advice is disconnected from people's lived experiences. This research investigated how people construct personal thresholds of 'too much' alcohol. Design and measures: One hundred fifty drinkers completed an online survey (M_age = 23.29(5.51); 64.7% female). Participants were asked whether they had an intuitive sense of what constitutes too much alcohol. They wrote open-ended descriptions of how that threshold had been established and how it felt to approach/exceed it. These qualitative accounts were coded using thematic analysis and interpreted with an experiential theoretical framework. Results: Personal thresholds were based on previously experienced embodied states rather than guidelines, or health concerns. Describing the approach to their threshold, 75% of participants fell into two distinct groups. Group 1's approach was an entirely negative embodied experience (nausea/anxiety) and Group 2's approach was an entirely positive, embodied experience (relaxed/pleasurable). These groups differed significantly in awareness of alcohol's effects, agency and self-perceptions, but not on alcohol consumption. Exceeding their threshold was an entirely negative embodied experience for all. Conclusion: These findings illustrate that people are guided by experientially grounded conceptions of consumption. Interventions could target different groups of drinker according to their embodied experience during the approach to 'too much' alcohol.

Alcohol-related harm to others in England: a cross-sectional analysis of national survey data

OBJECTIVES

To estimate the prevalence, the frequency and the perpetrators of alcohol-related harm to others (AHTO) and identify factors associated with experiencing harm and aggressive harm.

DESIGN

Cross-sectional survey.

SETTING

England.

PARTICIPANTS

Adults (general population) aged 16 and over.

OUTCOME MEASURES

Percentage of respondents who experienced harm. Socioeconomic and demographic factors associated with the outcomes. Outcomes were (1) experienced harm/did not experience harm and (2) experienced aggressive harm (physically threatened, physically hurt and forced/pressured into something sexual)/did not experience an aggressive harm (no aggressive harm plus no harm at all).

RESULTS

Data to support a response rate calculation were not collected; 96.3% of people surveyed completed the AHTO questions. The weighted sample was 4874; 20.1% (95% CI 18.9 to 21.4, N=980) reported experiencing harm in the previous 12 months and 4.6% (95% CI 4.0 to 5.4, N=225) reported experiencing an aggressive harm. Friends and strangers were the dominant perpetrators. Most harms (74.8%) occurred less than monthly. Factors associated with experiencing harm were: younger age (p<0.001), drinking harmfully/hazardously (p<0.001), white British (p<0.001 compared to other white groups and Asian groups and p=0.017 compared to black groups), having a disability (p<0.001), being educated (p<0.001 compared to no education) and living in private rented accommodation (p=0.004 compared with owned outright). Being in the family stage of life (defined as having children in the household) had significantly lower odds of harm (p=0.006 compared to being single), as did being retired (p<0.001 compared to being employed). Factors associated with experiencing an aggressive harm were similar.

CONCLUSIONS

This exploratory study, using data collected through the Alcohol Toolkit Survey, shows that AHTO affects 20.1% of the population of England. Even apparently minor harms, like being kept awake, can have a negative impact on health, while aggressive harms are clearly of concern. Using a standard methodology to measure harm across studies would be advantageous. Policies that focus on alcohol must take into consideration the impact of drinking on those other than the drinker.

The Role of Sex and Age on Pre-drinking: An Exploratory International Comparison of 27 Countries

Aims

This exploratory study aims to model the impact of sex and age on the percentage of pre-drinking in 27 countries, presenting a single model of pre-drinking behaviour for all countries and then comparing the role of sex and age on pre-drinking behaviour between countries.

Methods

Using data from the Global Drug Survey, the percentages of pre-drinkers were estimated for 27 countries from 64,485 respondents. Bivariate and multivariate multilevel models were used to investigate and compare the percentage of pre-drinking by sex (male and female) and age (16–35 years) between countries.

Results

The estimated percentage of pre-drinkers per country ranged from 17.8% (Greece) to 85.6% (Ireland). The influence of sex and age on pre-drinking showed large variation between the 27 countries. With the exception of Canada and Denmark, higher percentages of males engaged in pre-drinking compared to females, at all ages. While we noted a decline in pre-drinking probability among respondents in all countries after 21 years of age, after the age of 30 this probability remained constant in some countries, or even increased in Brazil, Canada, England, Ireland, New Zealand and the United States.

Conclusions

Pre-drinking is a worldwide phenomenon, but varies substantially by sex and age between countries. These variations suggest that policy-makers would benefit from increased understanding of the particularities of pre-drinking in their own country to efficiently target harmful pre-drinking behaviours.

Ideal, expected and perceived descriptive norm drunkenness in UK nightlife environments: a cross-sectional study

Background

Drunkenness is common in nightlife environments and studies suggest it can be considered both desirable and normal by nightlife users. We aimed to compare UK nightlife users’ ideal levels of drunkenness to their expected drunkenness on a night out and their perceptions of descriptive nightlife norms.

Methods

A cross-sectional survey with nightlife patrons (n = 408, aged 18–35) in three cities. Using a scale from 1 (completely sober) to 10 (very drunk), participants rated: personal drunkenness at survey; expected drunkenness on leaving nightlife; perceived descriptive drunkenness norm in the city’s nightlife; and ideal personal drunkenness. Analyses were limited to those who had or were intending to consume alcohol.

Results

Almost half of participants (46.8%) expected to get drunker than their reported ideal level on the night of survey, rising to four fifths of those with the highest levels of expected drunkenness. 77.9% rated typical nightlife drunkenness ≥8 but only 40.9% expected to reach this level themselves and only 23.1% reported their ideal drunkenness as ≥8. Higher expected drunkenness was associated with higher ideal drunkenness, higher perceived drunkenness norm and later expected home time.

Conclusions

Nightlife users’ perceptions of typical drunkenness in nightlife settings may be elevated and many of the heaviest drinkers are likely to drink beyond their ideal level of drunkenness. Findings can support emerging work to address cultures of intoxication in nightlife environments and suggest that interventions to correct misperceptions of normal levels of nightlife drunkenness may be of benefit.

Typology of Nightclubs in São Paulo, Brazil: Alcohol and Illegal Drug Consumption, Sexual Behavior and Violence in the Venues

BACKGROUND

Nightclubs are venues in which excessive alcohol use and illegal drug consumption occur in addition to other high-risk behaviors, such as violence and sexual risk behaviors. Environmental factors common in nightclubs and the personal characteristics of patrons might increase the risk of these events. To better understand the relationship between these factors, typologies were formulated that clustered nightclubs according to definite profiles to identify differences to be taken into consideration in preventive interventions.

OBJECTIVES

The present study aim was to construct a typology of nightclubs in São Paulo, Brazil.

METHODS

This typology was constructed using mixed methods research through the triangulation of several data sources as follows: 307 hours of ethnographic observation at 31 nightclubs, 8 focus group sessions with nightclub patrons (n = 34) and 30 semi-structured interviews with nightclub employees. Content analysis and qualitative typology were used.

RESULTS

Four nightclub types were defined based on four analyzed thematic axes (Intoxicating, Violent, Dancing and Highly Sexualized nightclubs). Excessive alcohol use was detected in almost all of the investigated nightclubs, and drug use was observed in approximately one-third of them. Triangulation of the data revealed a relationship among environmental factors (especially alcohol sales strategies and promotion and the availability of areas for sex) and a more considerable presence of high-risk behaviors.

CONCLUSIONS

The study shows that nightclubs are settings in which high-risk behaviors are potentiated by facilitating environmental factors as well as by the lack of laws restricting excessive alcohol use stimulated by the promotion strategies applied at these venues.

Risk Factors Related to Binge Drinking

The characteristics of and risk factors associated with binge drinking among South Korean and American adolescents were identified in this study. Data on adolescents in the 9th to 12th grades were extracted from two nationwide data sets: the Korea Youth Risk Behavior Web-based Survey System and the U.S. Youth Risk Behavior Surveillance System. Binge drinking was observed among 16% of American adolescents during the past month and among 11.6% of Korean adolescents during the past year. For adolescents from both countries, the following seven similar significant factors were associated with binge drinking: female gender, higher grade, fighting-related injury experience, current cigarette smoking, preteen smoking initiation, participation in team sports, and depression. Among Korean adolescents, higher or lower level of academic achievement and inadequate sleep were additional unique factors associated with binge drinking. These results could be useful for developing interventions for adolescents engaging in binge drinking in both countries.

Are ecstasy induced serotonergic alterations overestimated for the majority of users?

BACKGROUND

Neuroimaging studies imply that the regular use of ±3,4-methylenedioxymethamphetamine (MDMA), the major constituent of ecstasy pills, alters the brain's serotonergic system in a dose-dependent manner. However, the relevance of these findings remains unclear due to limited knowledge about the ecstasy/MDMA use pattern of real-life users.

AIMS

We examined the representativeness of ecstasy users enrolled in neuroimaging studies by comparing their ecstasy use habits with the use patterns of a large, international sample.

METHODS

A systematic literature search revealed 10 imaging studies that compare serotonin transporter levels in recreational ecstasy users to matched controls. To characterize the ecstasy use patterns we relied on the Global Drug Survey, the world's largest self-report database on drug use. The basis of the dose comparison were the Usual Amount (pills/session), Use Frequency (sessions/month) and Dose Intensity (pills/year) variables.

RESULTS

Both the average Usual Amount (pills/session) and Use Frequency (sessions/month) of neuroimaging study participants corresponded to the top 5-10% of the Global Drug Survey sample and imaging participants, on average, consumed 720% more pills over a year than the Global Drug Survey participants.

CONCLUSIONS

Our findings suggest that the serotonin brain imaging literature has focused on unusually heavy ecstasy use and therefore the conclusions from these studies are likely to overestimate the extent of serotonergic alterations experienced by the majority of people who use ecstays.

Polysubstance use and misuse or abuse of prescription opioid analgesics: a multi-level analysis of international data

Increasing mortality and morbidity associated with opioid analgesics has led to concerns about their misuse and abuse, even when obtained through a prescription. These concerns have been most pronounced in the United States, but limited data make it difficult to determine whether it is a problem in other countries. We investigated opioid analgesic misuse and abuse in participants from the Global Drug Survey 2015 resident in the United States (N = 1334), United Kingdom (N = 1199), France (N = 1258), Germany (N = 866), and Australia (N = 1013) who had used at least 1 prescription opioid analgesic medication in the past year. We also investigated the relationship with polysubstance use, one of the most consistent predictors of problematic opioid analgesic use. Data included misuse and abuse of codeine, hydrocodone, oxycodone, and tramadol; ability to obtain a prescription; different sources for obtaining drugs; and past-year use of benzodiazepines and illicit drugs. In multilevel models, country of residence accounted for less than 3% of the variance in opioid analgesic misuse or abuse. Adjusting for country of residence and sociodemographic factors, use of illicit drugs and benzodiazepines was associated with 4-fold greater odds of misuse (odds ratio 4.36, 95% confidence interval 3.29-5.93) and 6-fold greater odds of abuse compared with not using either drug (odds ratio 6.49, 95% confidence interval 4.0-10.48), although the strength of the association with abuse varied by country. Misuse and abuse by those prescribed opioid analgesics seem to be a problem that is not limited to the United States and warrant attention on an international scale.

Gender Differences in Binge Drinking

Just as binge drinking rates differ for men and women, the predictors and consequences of binge drinking vary by gender as well. This article examines these differences and how binge drinking definitions and research samples and methods may influence findings. It also describes the relationship between age and binge drinking among men and women, and how drinking culture and environment affect this relationship. It examines gender-specific trends in binge drinking, predictors of binge drinking for men and women, and binge drinking in the context of smoking. The article reviews current findings on gender differences in the health consequences of binge drinking, including morbidity and mortality, suicidality, cancer, cardiovascular disorders, liver disorders, and brain and neurocognitive implications. It also discusses gender differences in the behavioral and social consequences of binge drinking, including alcohol-impaired driving, sexual assault, and intimate partner violence, and includes implications for treatment and prevention.

Do emotions related to alcohol consumption differ by alcohol type? An international cross-sectional survey of emotions associated with alcohol consumption and influence on drink choice in different settings

OBJECTIVES

To examine the emotions associated with drinking different types of alcohol, explore whether these emotions differ by sociodemographics and alcohol dependency and whether the emotions associated with different drink types influence people's choice of drinks in different settings.

DESIGN

International cross-sectional opportunistic survey (Global Drug Survey) using an online anonymous questionnaire in 11 languages promoted through newspapers, magazines and social media from November 2015 to January 2016.

STUDY POPULATION

Individuals aged 18-34 years who reported consumption of beer, spirits, red and white wine in the previous 12 months and were resident in countries with more than 200 respondents (n=21 countries; 29 836 respondents).

MAIN OUTCOME MEASURES

Positive and negative emotions associated with consumption of different alcoholic beverages (energised, relaxed, sexy, confident, tired, aggressive, ill, restless and tearful) over the past 12 months in different settings.

RESULTS

Alcoholic beverages vary in the types of emotions individuals report they elicit, with spirits more frequently eliciting emotional changes of all types. Overall 29.8% of respondents reported feeling aggressive when drinking spirits, compared with only 7.1% when drinking red wine (p<0.001). Women more frequently reported feeling all emotions when drinking alcohol, apart from feelings of aggression. Respondents' level of alcohol dependency was strongly associated with feeling all emotions, with the likelihood of aggression being significantly higher in possible dependent versus low risk drinkers (adjusted OR 6.4; 95% CI 5.79 to 7.09; p<0.001). The odds of feeling the majority of positive and negative emotions also remained highest among dependent drinkers irrespective of setting.

CONCLUSION

Understanding emotions associated with alcohol consumption is imperative to addressing alcohol misuse, providing insight into what emotions influence drink choice between different groups in the population. The differences identified between sociodemographic groups and influences on drink choice within different settings will aid future public health practice to further comprehend individuals' drinking patterns and influence behaviour change.

Moving on From Representativeness: Testing the Utility of the Global Drug Survey

A decline in response rates in traditional household surveys, combined with increased internet coverage and decreased research budgets, has resulted in increased attractiveness of web survey research designs based on purposive and voluntary opt-in sampling strategies. In the study of hidden or stigmatised behaviours, such as cannabis use, web survey methods are increasingly common. However, opt-in web surveys are often heavily criticised due to their lack of sampling frame and unknown representativeness. In this article, we outline the current state of the debate about the relevance of pursuing representativeness, the state of probability sampling methods, and the utility of non-probability, web survey methods especially for accessing hidden or minority populations. Our article has two aims: (1) to present a comprehensive description of the methodology we use at Global Drug Survey (GDS), an annual cross-sectional web survey and (2) to compare the age and sex distributions of cannabis users who voluntarily completed (a) a household survey or (b) a large web-based purposive survey (GDS), across three countries: Australia, the United States, and Switzerland. We find that within each set of country comparisons, the demographic distributions among recent cannabis users are broadly similar, demonstrating that the age and sex distributions of those who volunteer to be surveyed are not vastly different between these non-probability and probability methods. We conclude that opt-in web surveys of hard-to-reach populations are an efficient way of gaining in-depth understanding of stigmatised behaviours and are appropriate, as long as they are not used to estimate drug use prevalence of the general population.

Energy drink use frequency among an international sample of people who use drugs: Associations with other substance use and well-being

OBJECTIVE

The study aims were to identify: i.) energy drink (ED), caffeine tablet, and caffeine intranasal spray use amongst a sample who report drug use, and ii.) the association between ED use frequency and demographic profile, drug use, hazardous drinking, and wellbeing.

METHOD

Participants (n=74,864) who reported drug use completed the online 2014 Global Drug Survey. They provided data on demographics, ED use, and alcohol and drug use, completed the Alcohol Use Disorders Identification Test (AUDIT) and Personal Wellbeing Index (PWI), and reported whether they wished to reduce alcohol use.

RESULTS

Lifetime ED, caffeine tablet and intranasal caffeine spray use were reported by 69.2%, 24.5% and 4.9%. Median age of ED initiation was 16 years. For those aged 16-37, median years using EDs increased from 4 to 17 years of consumption, where it declined thereafter. Greater ED use frequency was associated with: being male; under 21 years of age; studying; and past year caffeine tablet/intranasal spray, tobacco, cannabis, amphetamine, MDMA, and cocaine use. Past year, infrequent (1-4days) and frequent (≥5days) past month ED consumers reported higher AUDIT scores and lower PWI scores than lifetime abstainers; past month consumers were less likely to report a desire to reduce alcohol use.

CONCLUSIONS

ED use is part of a complex interplay of drug use, alcohol problems, and poorer personal wellbeing, and ED use frequency may be a flag for current/future problems. Prospective research is required exploring where ED use fits within the trajectory of other alcohol and drug use.

Conceptual and Methodological Issues in Studying Alcohol's Harm to Others1

While there is a longer history of concern about alcohol's harm to others, researchers' interest has intensified in the last few years. The background of variation in concern over time in different societies is outlined. Three main traditions of research have emerged: population survey studies of such harm from the perspective of the ‘other’; analysis of register or case-record data which includes information on the involvement of another's drinking in the case; and qualitative studies of interactions and experiences involved in particular harms from others' drinking. In the course of the new spate of studies, many conceptual and methodological issues have arisen, some of which are considered in the paper. The diverse types of harms which have been studied are discussed. The social and personal nature of many of the harms means they do not ft easily into a disability or costing model, raising questions about how they might best be counted and aggregated. Harm from others' drinking is inherently interactional, and subject to varying definitions of what counts as harm. The attribution to drinking, in the usual situation of conditional causation, is also subject to variation, with moral politics potentially coming into play. For measurement and comparison, account needs to be taken of cultural and individual variations in perceptions and thresholds of what counts as a harm, and attribution to alcohol. The view from the windows of a population survey and of a response agency case register are often starkly different, and research is needed, as an input and spur to policy initiatives, on what influences this difference and whether and how the views might be reconciled.
