Scoping review of assessment tools for, magnitudes of and factors associated with problem drinking in population-based studies

BackgroundThe term “problem drinking” includes a spectrum of alcohol problems ranging from excessive or heavy drinking to alcohol use disorder. Problem drinking is a leading risk factor for death and...

Social disparities in alcohol's harm to others: evidence from 32 European countries.

Alcohol use can cause harm not only to the person who consumes it but also to others. Prior research has found that these alcohol-attributable harms to others differ across socioeconomic groups, though several findings have been contradictory. The aim of this contribution was to study the role of individual-level and population-level income inequalities in alcohol's harm to others among women and men. Logistic regression analysis of cross-sectional survey data from 2021, covering 39,629 respondents from 32 European countries. Harms from others' drinking were defined as experiences of physical harm, involvement in a serious argument, or involvement in a traffic accident, due to another person's drinking, within the past year. We examined the association of individual-level income and country-specific income inequality (Gini index) with harms from a known person's or a stranger's drinking, adjusting for the respondent's age, daily drinking levels, and at least monthly risky single-occasion drinking. At the individual level, people with lower incomes had 21% to 47% increased odds of reporting harms from a known person's drinking (women and men) or stranger's drinking (men only) than their same-gender counterparts in the highest income quintile. At the national level, countries with higher income inequality showed increased risks of harms from a known person's drinking among women (OR=1.09, 95% confidence interval [CI]: 1.05 - 1.14), while among men the risk of harm from strangers' drinking decreased with higher income inequality (OR=0.86, 95% CI: 0.81 - 0.92). These associations with income inequality were observed among respondents from all but the lowest income groups. Alcohol can cause harm to others, with women and people with low incomes being disproportionally exposed to these harms. Alcohol control policies targeting high consumption levels, especially among men, as well as upstream policies to reduce inequalities, are needed to lower the health burden of alcohol beyond those who consume it.

Social and contextual factors associated with drinking before, during and after watching Australian Football League games: A pilot ecological momentary assessment study.

The aim of this study was to: (i) determine the feasibility of using ecological momentary assessment to collect data from Australian Football League (AFL) fans; (ii) explore pre-game, during-game and post-game consumption patterns of AFL fans; and (iii) explore the social and setting-related factors associated with risky single occasion drinking (5+ drinks) among AFL fans. Thirty-four participants completed up to 10 ecological momentary assessment surveys before, during and after 63 AFL games (n = 437 completed surveys). Surveys collected data about their drinking, and their social and environmental milieu (e.g., location, company). Binary logistic regression analyses clustered by participant identified which game-day characteristics were associated with higher odds of risky single occasion drinking. Significant differences between pre-game, during-game and post-game drinking on social and environmental factors were explored using pairwise comparisons. Risky single occasion drinking was more likely when games began in the early-afternoon (1-3 pm) than late-afternoon (3-6 pm), when participants watched the game at a stadium or pub compared to home, and when participants watched the game with friends compared to family. Pre-drinking was more likely before night games and post-drinking was more likely after day games. Drinking during the game was heavier when watching the game at a pub and when watching with a combined group of friends and family. Preliminary findings suggest that social and contextual factors matter in the way alcohol is consumed while watching AFL games. These findings require further investigation in larger samples.

Unrecorded alcohol use in 33 European countries: Analyses of a comparative survey with 49,000 people who use alcohol.

Using data from 33 European countries (including all EU member states), this study aimed to 1) estimate the prevalence of unrecorded alcohol use among past-week alcohol users, 2) describe how unrecorded alcohol use is associated with drinking patterns, and 3) estimate the contribution of unrecorded alcohol to the total amount of alcohol consumed annually in these countries. Data from 25,728 adults who drank alcohol in the past week and self-reported their use of unrecorded alcohol in 2021 were analysed. Prevalence of unrecorded alcohol use in the last week was estimated for those with low, medium, and high risk drinking categorised using the WHO-recommended risk thresholds and definition of risky single occasion drinking. Prevalence estimates were weighted for the country-specific gender, age, and geographical population distribution. An adjusted weighted proportion of unrecorded drinking occasions in total drinking occasions was calculated and compared to 2020 recorded annual per capita consumption estimates. Among past-week alcohol users, the average prevalence of past-week unrecorded alcohol use was 12.1% (95% CI: 11.7-12.5%), with considerable difference between countries (min: 2.0% in Malta; max: 27.0% in Greece). Unrecorded alcohol use was much more prevalent among people with high-risk alcohol use in the past week (24.2%, 95% confidence interval [CI]: 22.9-25.5%) compared to people with low- (6.5, 95% CI: 6.0-6.9%) or medium-risk alcohol intake in the past week (13.6%, 95% CI: 12.9-14.3%). Unrecorded alcohol accounted for 7% of per capita consumption in 2020. This is the first comparable assessment of unrecorded alcohol use across EU and affiliated countries. The findings add support to the observation that availability of unrecorded alcohol may contribute torisky drinking in Europe. The observed country variations may be related to differences in country-specific pricing policies and measures to reduce the production and consumption of unrecorded alcoholic beverages.

The Impact of the COVID-19 Pandemic on Young Adults' Mental Health in Switzerland: A Longitudinal Cohort Study from 2018 to 2021.

Most of the studies that examine the effect of the COVID-19 pandemic on mental health have been restricted to pandemic mental health data alone. The aim of the current study was to estimate the pandemic's effect on young Swiss adults' mental health by comparing pandemic to pre-pandemic mental health. Longitudinal data of 1175 young Swiss adults who participated in the S-YESMH study in 2018 and were followed-up in 2020 and 2021 were analyzed. The study outcomes were self-reported symptoms of depression, generalized anxiety disorder (GAD), attention-deficit/hyperactivity disorder (ADHD), thoughts about death or self-harm, and risky single-occasion drinking (RSOD). Generalized estimation equations, logistic regression and statistical mediation analysis were used to analyze the data. Evidence was found of increased depression, GAD, and ADHD among young women and increased depression among young men, resulting from the COVID-19 pandemic. Uncertainty about the future predicted young women's depression and anxiety in 2021. COVID-19 stress in 2021 fully mediated the effect of COVID-19 stress in 2020 on depression and GAD in 2021. Young Swiss women's and men's mental health appears to have been adversely affected by the COVID-19 pandemic, especially during the second pandemic year. Uncertainty about the future and stress becoming chronic in 2021 likely explain some of the adverse effects.

Young Swiss men’s risky single-occasion drinking: Identifying those who do not respond to stricter alcohol policy environments

BackgroundPrevious research has demonstrated a preventive effect of the alcohol policy environment on alcohol consumption. However, little is known about the heterogeneity of this effect. Our aim was to examine the extent of heterogeneity in the relationship between the strictness of alcohol policy environments and heavy drinking and to identify potential moderators of the relationship. MethodsCross-sectional data from 5986 young Swiss men participating in the cohort study on substance use risk factors (C-SURF) were analysed. The primary outcome was self-reported risky single-occasion drinking in the past 12 months (RSOD, defined as 6 standard drinks or more on a single occasion at least monthly). A previously-used index of alcohol policy environment strictness across Swiss cantons was analysed in conjunction with 21 potential moderator variables. Random forest machine learning captured high-dimensional interaction effects, while individual conditional expectations captured the heterogeneity induced by the interaction effects and identified moderators. ResultsPredicted subject-specific absolute risk reductions in RSOD risk ranged from 16.8% to − 4.2%, indicating considerable heterogeneity. Sensation seeking and antisocial personality disorder (ASPD) were major moderators that reduced the preventive relationship between stricter alcohol policy environments and RSOD risk. They also were associated with the paradoxical observation that some individuals displayed increased RSOD risk in stricter alcohol policy environments. ConclusionWhereas stricter alcohol policy environments were associated with reduced average RSOD risk, additionally addressing the risk conveyed by sensation seeking and ASPD would deliver an interlocking prevention mix against young Swiss men’s RSOD.

Alcohol consumption trajectories over the Australian life course.

Background and AimsAlcohol consumption changes markedly over the life course, with important implications for health and social development. Assessment of these patterns often relies on cross‐sectional data, which cannot fully capture how individuals' drinking changes as they age. This study used data from 18 waves of a general population panel survey to measure drinking trajectories over the life course in Australia.Design and SettingLongitudinal survey data from the Household, Income and Labour Dynamics in Australia (HILDA) survey between 2001 and 2018.ParticipantsA total of 20 593 individuals ages 15 or above in two samples assessing quantity‐frequency (n = 20 569, 52.0% female) and risky single occasion drinking (RSOD), respectively, (n = 17 340, 52.5% female), interviewed as part of HILDA.MeasurementsUsual quantity of alcohol consumed per drinking occasion; frequency of drinking occasions per week; average daily consumption, calculated by combining reported usual quantity and frequency; and average reported frequency of RSOD per week.FindingsMultilevel, mixed effects models run with fractional polynomial terms found similar male and female alcohol consumption trajectories for quantity‐frequency and RSOD measures. Usual quantity of alcohol consumed per drinking occasion (5.4 drinks for men, 3.8 for women) and RSOD frequency (0.56 occasions/week for men, 0.38 for women) peaked in young adulthood, whereas frequency of drinking occasions (2.5 occasions/week for men, 1.7 for women) peaked in middle age. Middle‐age drinkers had the highest average daily consumption of alcohol (1.4 drinks/day for 54‐year‐old men, 0.6 drinks for 57‐year‐old women) and engaged in RSOD slightly less than young adults.ConclusionsAlcohol consumption in Australia appears to vary substantially over the life course, with usual quantity per drinking occasion and frequency of risky single occasion drinking peaking during early adulthood and average daily consumption and frequency of consumption peaking in middle age.

The who and what of women's drinking: Examining risky drinking and associated socio-demographic factors among women aged 40-65 years in Australia.

Recent trends in Australian national survey data show an increase in alcohol use among middle-aged people, amidst declines in alcohol use among other population groups. There is limited research, however, on middle-aged women's alcohol use. This study aimed to examine patterns in alcohol use among Australian women aged 40-65 and the associated sociodemographic and contextual factors. Cross-sectional data from six waves of the National Drug Strategy Household Survey (2001-2019). We estimated the prevalence of long-term risky drinking (>2 Australian standard drinks per day) and risky-single occasion drinking (>5 Australian standard drinks on one occasion) among middle-aged women. Logistic regression models were estimated using 2019 data to examine demographic characteristics and contextual factors associated with alcohol use. Since 2001, there has been a statistically significant increase in long-term risky drinking and risky-single occasion drinking amongst middle-aged women in Australia. Educational attainment, marital status and employment status were negatively associated with risky drinking, whereas rurality, age and location of use were positively associated with risky drinking. Beverage type was both positively and negatively associated with risky drinking. Given the significant increase in alcohol use amongst middle-aged women in Australia, prevention efforts are needed for this group, which may focus in particular on home drinking and the impact of rurality on alcohol use.

Evidence of substantial heterogeneity in the preventive effect of stricter alcohol policy environments in young Swiss men

IntroductionThe alcohol policy environment was shown to exert a preventive effect on alcohol consumption. However, little is known about the heterogeneity of this effect.ObjectivesTo capture the extent of heterogeneity in the relationship between the strictness of alcohol policy environments and heavy drinking and to identify potential effect modifiers.MethodsMethod: Cross-sectional data from 5986 young Swiss men participating in the cohort study on substance use risk factors (C-SURF) in Switzerland was analysed. Self-reported risky single-occasion drinking (RSOD, drinking 6 standard drinks or more on a single occasion at least monthly) in the past 12 months was the outcome of interest. A previously-used index of alcohol policy environment strictness across Swiss cantons was analysed in conjunction with 21 potential effect modifiers. Random forest machine learning and individual conditional expectations captured high-dimensional interaction effects and the heterogeneity induced by the interaction effects and identified potential effect modifiers.ResultsSubject-specific absolute risk reductions ranged from 16.8% to -4.2%, with the latter implying a risk increase. Four prototypical subgroups were evident: “preventive” (alcohol policy environment decreased RSOD risk), “causative” (alcohol policy environment increased RSOD risk), “immune” (no effect due to low RSOD baseline risk), and “doomed” (no effect due to high RSOD baseline risk). Antisocial personality disorder and sensation seeking were major effect modifiers that reduced the preventive effect of stricter alcohol policy environments.ConclusionsConclusion: Whereas stricter alcohol policy environments were associated with a reduced RSOD risk, adding selective prevention measures that target high-risk subpopulations is necessary.DisclosureNo significant relationships.

Performance of self-reported measures of alcohol use and of harmful drinking patterns against ethyl glucuronide hair testing among young Swiss men.

There is a need for empirical studies assessing the psychometric properties of self-reported alcohol use as measures of excessive chronic drinking (ECD) compared to those of objective measures, such as ethyl glucuronide (EtG). To test the quality of self-reported measures of alcohol use and of risky single-occasion drinking (RSOD) to detect ECD assessed by EtG. A total of 227 samples of hair from young Swiss men were used for the determination of EtG. Self-reported measures of alcohol use (previous twelve-month and previous-week alcohol use) and RSOD were assessed. Using EtG (<30 pg/mg) as the gold standard of ECD assessment, the sensitivity and specificity were computed, and the AUROC were compared for alcohol use measures and RSOD. Logistic regressions were used to test the contribution of RSOD to the understanding of ECD after controlling for alcohol use. A total of 23.3% of participants presented with ECD. Previous twelve-month alcohol use with a cut-off of >15 drinks per week (sensitivity = 75.5%, specificity = 78.7%) and weekly RSOD (sensitivity = 75.5%, specificity = 70.1%) yielded acceptable psychometric properties. No cut-off for previous-week alcohol use gave acceptable results. In the multivariate logistic regression, after controlling for the previous twelve months of alcohol use, RSOD was still significantly associated with EtG (p = .016). Self-reported measures of the previous twelve months of alcohol use and RSOD were acceptable measures of ECD for population-based screening. Self-reported RSOD appeared to be an interesting screening measure, in addition to the previous twelve months of alcohol use, to understand ECD among young people.

Drinking to cope mediates the link between work-family conflict and alcohol use among mothers but not fathers of preschool children

Based on the assumptions of emotion regulation theory, this study tests whether drinking to cope mediates the association between work-family conflict (WFC) and alcohol use; an important link missing in previous studies. Based on a sample of 144 fathers and 165 mothers of pre-schoolers in Switzerland, Poisson regression mediation models were estimated. Models were adjusted for other drinking motives, age, and employment level. The results revealed that, among mothers, coping motives fully mediated the effect of WFC on frequency of risky single occasion drinking (IRR direct effect = 0.969, p > .05; IRR indirect effect = 1.043, p < .05) and partially mediated the link between WFC and usual quantity per drinking day (IRR direct effect = 1.181, p < .01; IRR indirect effect = 1.035, p < .05). Among fathers, no effect of WFC on alcohol use was found and consequently no mediation of coping motives. The findings suggest that mothers who drink to cope are at risk of excessive drinking, particularly when experiencing WFC. This puts them at risk for long-term health consequences when the stress and negative affects resulting from WFC are not adequately addressed. Intervention efforts should focus on women who drink for coping motives by providing them with support and non-drinking alternatives.

Effectiveness of an Ecological Momentary Intervention for Reducing Risky Alcohol Consumption Among Young Adults: Protocol for a Three-Arm Randomized Controlled Trial.

BackgroundRecent research has investigated the utility of mobile phone–delivered interventions for reducing risky single-occasion drinking, also known as binge drinking. In the past five years, focus has been placed on ecological momentary interventions (EMIs), which aim to deliver intervention content in correspondence to real-time assessments of behavior, also known as ecological momentary assessments (EMAs).ObjectiveThis study aims to assess the effect of a fully automated, tailored, mobile phone–delivered EMI termed Mobile Intervention for Drinking in Young people (MIDY) on young people's risky single-occasion drinking behavior.MethodsWe will use a three-armed randomized controlled trial design to determine the impact of MIDY on peak consumption of alcohol among young people. A list of mobile telephone numbers for random digit dialing will be generated, and researchers will telephone potential participants to screen for eligibility. Participants will be randomized into one of three intervention groups. For 6 weeks, EMI, EMA, and attention control groups will complete hourly EMA surveys on their mobile phones on Friday and Saturday nights. EMI participants will receive personalized feedback in the form of text messages corresponding to their EMA survey responses, which focus on alcohol consumption, spending, and mood. EMA participants will not receive feedback. A third group will also complete EMA and receive feedback text messages at the same time intervals, but these will be focused on sedentary behavior and technology use. All groups will also complete a short survey on Saturday and Sunday mornings, with the primary outcome measure taken on Sunday mornings. A more detailed survey will be sent on the final Sunday of the 6-week period, and then again 1 year after recruitment.ResultsThe primary outcome measure will be an observed change (ie, reduction) in the mean peak number of drinks consumed in a single night over the 6-week intervention period between the EMI and attention control groups as measured in the weekly EMA. We expect to see a greater reduction in mean peak drinking in the EMI group compared to that in the attention control group. As a secondary aim, we will assess whether mean peak drinking is reduced in the EMA group compared to the attention control group. We will use a random-effects mixed-modeling approach using maximum-likelihood estimation to provide estimates of differences in peak drinking across time periods between those receiving the intervention (EMI) and attention control participants. An intention-to-treat approach will be taken for the analysis. Individuals and study groups will be modeled as random and fixed factors, respectively.ConclusionsThis study extends our previous work investigating the efficacy of a mobile EMI (MIDY) for reducing risky drinking among young adults in Australia, and will add to the expanding literature on the use of mobile interventions for reducing risky alcohol consumption.Trial RegistrationAustralian New Zealand Clinical Trials Registration (ANZCTR): ACTRN12617001509358p; http://www.anzctr.org.au/ACTRN12617001509358p.aspxInternational Registered Report Identifier (IRRID)DERR1-10.2196/14190

A Multilevel Analysis of Regional and Gender Differences in the Drinking Behavior of 23 Countries

Introduction: Drinking behavior differs not only among countries, but also among regions within a country. However, the extent of such variation and the interplay between gender and regional differences in drinking have not been explored and are addressed in this study. Methods: Data stem from 105,061 individuals from 23 countries of the GENACIS data set. The outcomes were heavy drinking (10/20 g or more of pure ethanol per day for women/men), and risky single occasion drinking (RSOD) (5+ drinks per occasion) at least monthly. Analyses used binary logistic mixed models. Variance at specific levels was measured by the intra-class correlation coefficient (ICC). Gender differences in outcomes were measured using gender ratios. Results: Country-level ICC was 0.13 (95% CI: 0.09–0.18) for heavy drinking and 0.16 (95% CI: 0.10–0.26) for RSOD. Within-country regional-level ICC for heavy drinking and RSOD was 0.02 (95% CI: 0.009–0.05; 0.01–0.04, respectively), implying that 2% of variation in heavy drinking and RSOD was explained by regional variation. Variance in drinking indicators was larger for women compared to men across countries. Gender ratios were higher in low- and middle-income countries. Conclusions: Regional variations in risky drinking were more often present in low- to middle-income countries as well as in a few higher-income countries, and could be due to cultural and demographic differences. Variations in gender differences were larger on the country level than on the regional level, with lower-income countries showing larger differences. These results can help to better identify specific high-risk groups for prevention strategies.

Problematic smartphone use in young Swiss men: Its association with problematic substance use and risk factors derived from the pathway model.

Background and aimsThis study aimed to examine associations between risk factors suggested in the pathway model proposed by Billieux et al., demographic and substance use variables, and problematic smartphone use (PSU).MethodsThe analytical sample consisted of 5,096 Swiss men (mean age = 25.5 years, SD = 1.26). Multiple linear regression analyses were conducted with PSU as dependent and the following as independent variables: (a) Billieux’s pathway model variables (depression, social anxiety, ADHD, aggression–hostility, and sensation seeking); (b) substance use variables [alcohol: at-risk risky single-occasion drinking (RSOD); at-risk volume drinking; tobacco use: daily smoking; illicit drug use: more than weekly cannabis use; having used at least one other illicit drug besides cannabis over the preceding 12 months]; and (c) sociodemographic variables (age, language region, and education).ResultsAll pathway-model variables except sensation seeking were significant predictors of PSU, especially symptoms of social anxiety (β = 0.196) and ADHD (β = 0.184). At-risk RSOD was positively (β = 0.071) associated with PSU, whereas both frequent cannabis use (β = −0.060) and daily cigarette smoking (β = −0.035) were negatively associated with PSU. Higher-achieved educational levels and being from the German-speaking part of Switzerland predicted PSU.Discussion and conclusionsThe findings of this study can be used to develop tailored interventional programs that address the co-occurrence of certain risky behaviors (e.g., at-risk RSOD and PSU) and target individuals who might be particularly prone to PSU. Such interventions would need to ensure that addressing one problem (e.g., decreasing PSU) does not lead to some other compensatory behavior (e.g., frequent cigarette smoking).

Assessment of heavy alcohol drinking among young Swiss men

There is a need of empirical evidence of the relationship between heavy alcohol use and alcohol markers. More precisely, associations of these markers with patterns of alcohol use, such as risky single occasion drinking (i.e., drinking 6 drinks or more on a single occasion) have been scarcely investigated. This study aimed to derive psychometric properties of alcohol markers in comparison with different measures of alcohol use and to test whether it allows detecting excessive alcohol use. Participants ( n = 233, male, around 20 years old) were recruited based on a stratified random selection of the Swiss Cohort Study on Substance Use and Risk Factors. Inclusion criterion was an Audit score ≥ 13. Assessments included a clinical interview based on the Diagnostic Interview for Genetic Studies (DIGS) and self-reported alcohol measures [1] . Hair ( n = 230) and capillary blood ( n = 233) on Hemaxis ® DBS device were collected for ethyl glucuronide (EtG) and phosphatidylethanol (PEth) determination, respectively. EtG was extracted from washed hair by micropulverized extraction and SPE purification. The extracts were submitted to LC-MS/MS analysis (6500 Qtrap Sciex). Chromatographic separation was achieved using a Merck Chromolith ® RP-C18e column (150 × 3 mm). The PEth homologs 16:0/18:1 and 16:0/18:2 concentrations were determined by LC-MS/MS (5000 Qtrap Sciex) according to a validated method [2] . For the interpretation, only the PEth homolog 16:0/18:1 were used. Statistical data treatment (ROC-analysis) was carried out using R software. EtG could be detected in 151 of 230 samples with concentrations ≥ 4.0 pg/mg (LOQ). The maximum measured concentration was 690 pg/mg. Twenty-five percent, 50% (median) and 75% percentiles were 6.8, 15, and 34 pg/mg, respectively. In 53 cases, EtG concentrations were ≥ 30 pg/mg, suggesting excessive alcohol consumption. The area under the ROC curve for EtG ≥ 30 pg/mg vs. PEth was 0.8322. In cases where PEth ≥ 210 ng/mL, more than 75% presented also EtG ≥ 30 pg/mg. PEth 16:0/18:1 detected in 218 of 233 samples with concentrations ≥ 10 ng/mL (LOQ). The maximum measured concentration was 1990 ng/mL. Twenty-five percent, 50% (median) and 75% percentiles were 71, 182, and 360 ng/ml, respectively. In 99 cases, PEth 16:0/18:1 concentrations ≥ 210 ng/mL, suggesting excessive alcohol consumption, were found. Compared to self-reported data (last week total alcohol intake diary), area under the ROC curve for PEth ≥ 210 ng/mL were 0.8174. For detecting a risky single occasion drinking (≥ 5 drinks at one occasion), the area under the ROC curve for PEth were 0.7955. EtG and PEth measurement allowed detecting excessive alcohol consumption with high specificity and sensitivity. Both marker are complementary and do not necessarily provide the same information because of their different detection window and change of consumption during the evaluation period. The results support the statement in the SoHT consensus for the use of alcohol markers: “It is not advisable to use the results of hair testing for alcohol markers in isolation” [3] .

Is there gender convergence in risky drinking when taking birth cohorts into account? Evidence from an Australian national survey 2001-13.

Recent studies have argued that there has been substantial gender convergence in alcohol consumption. However, many of these rely on comparisons of different cohorts and do not adjust for age differences in male and female drinking patterns. We aimed to examine (1) whether the gender gap in risky drinking in Australia narrowed between 2001 and 2013, (2) if the evidence for gender convergence (or divergence) was consistent across age groups and (3) how a cohort-focused analysis of gender convergence compared with an age-focused approach. Repeated cross-sectional data from five waves of the National Drug Strategy Household Survey (2001, 2004, 2007, 2010, 2013). Interaction terms in logistic and linear regression models were used to test for significantly different trends between men and women. Australia. Australians aged 14years and older (n=125 215) who provided data on alcohol consumption in the National Drug Strategy Household Survey. Prevalence of long-term risky drinking (average of 20g or more per day) and prevalence of risky single occasion drinking (12 or more sessions of 50g or more). Gender differences were large for all age groups except adolescents (14-17-year-olds), with men typically reporting levels of drinking at least twice as high as women across the study period. Overall, there was statistically significant gender convergence in alcohol use measures showing a slight decrease in men's drinking and a slight increase in women's drinking. However, when age-specific analyses were conducted gender convergence was only observed for 50-69-year-olds. In Australia, gender convergence in risky drinking since 2001 has been evident only in people aged 50-69years.

The relationship between socioeconomic status and risky drinking in Denmark: a cross-sectional general population study

BackgroundSocioeconomic status (SES) is regarded as consisting of education, income and employment. However, the relationship of these three components to alcohol use behaviours, such as risky single occasion drinking (RSOD) is unclear. The aim of the present paper is to specify how the three SES components relate to RSOD in a cross-sectional survey sample of the Danish general population.MethodData from a 2011 Danish national representative survey (n = 3600) was analysed by multiple logistic regression to assess the influence of three dimensions of individual SES (education, income, employment) on RSOD.ResultsComponents of SES were not found to be significantly associated with RSOD independently nor in combination.ConclusionIn the Danish context, SES was not associated with RSOD.

Is proximity to alcohol outlets associated with alcohol consumption and alcohol-related harm in Denmark?

Background:This study examined the associations between distance from residence to the nearest alcohol outlet with alcohol consumption as well as with alcohol-related harm.Methods:Data on alcohol consumption, alcohol-related harm and sociodemographics were obtained from the 2011 Danish Drug and Alcohol Survey (n = 5133) with respondents aged 15–79 years. The information on distances from residence to the nearest alcohol outlets was obtained from Statistics Denmark. Multiple logistic and linear regressions were used to examine the association between distances to outlets and alcohol consumption whereas alcohol-related harm was analysed using negative binomial regression.Results:Among women it was found that those living closer to alcohol outlets were more likely to report alcohol-related harm (p < 0.05). This was not true for men. No association was found between distances to outlets and alcohol consumption (volume of drinking and risky single occasion drinking).Conclusions:This study found some support for an association between closer distances between place of residence and alcohol outlets and alcohol-related harm for women. Future studies in the Nordic region should continue to examine the association between physical alcohol availability (nearest distance to an outlet and outlet densities) and alcohol consumption as well as alcohol-related problems using different outlet types.

Drinking patterns at the sub-national level: What do they tell us about drinking cultures in European countries?

Aim:A drinking pattern is not only a major drinking variable, but is also one indicator of a country’s drinking culture. In the present study, we examine drinking patterns within and across the neighbouring countries of Denmark and Germany. The aim of the research is to determine to what extent drinking patterns differ or are shared at the sub-national level in the two countries.Method:Data came from the German 2012 Epidemiological Survey of Substance Use (n = 9084) 18–64 years (response rate 54%), and the Centre for Alcohol and Drug Research’s 2011 Danish national survey (n = 5133) 15–79 years (response rate 64%), which was reduced to a common age range, producing a final n = 4016. The drinking pattern variable included abstention, moderate drinking, heavy drinking, risky single occasion drinking (RSOD), and was investigated with bivariate statistics and gender-specific hierarchical cluster analysis.Results:For men three clusters emerged: one highlighting abstention and RSOD, moderate/heavy drinking, RSOD and RSOD + heavy drinking. For women, two clusters appeared: one highlighting abstention and moderate/heavy drinking and the other highlighting RSOD and RSDO + heavy drinking. The clusters revealed different geographical patterning: for men, a west vs. east divide; for women, a north–south gradient.Conclusions:The analysis could identify for each gender clusters representing both separate and shared drinking patterns as well as distinctive geographical placements. This new knowledge can contribute to a new understanding of the dynamics of drinking cultures and could indicate new approaches to prevention efforts and policy initiatives.
