Prevalence Of Heavy Episodic Drinking Research Articles

Heavy episodic drinking among French adolescents between 2005 and 2022: decreasing prevalence rates and increased risks.

To study the prevalence of alcohol use among French adolescents over time and factors associated with heavy episodic drinking (HED) among drinkers. Our analysis relies on six waves of a standardized cross, sectional survey conducted in mainland France between 2005 and 2022. The overall sample size comprises 179905 adolescents aged 17 (90166 males and 89739 females). Two outcomes were considered: declaring past month HED (at least one) and repeated HED (at least three) in the past month between 2005 and 2022. Relative risks and probabilities according to years of survey, gender and frequency of alcohol use (past 30 days) were estimated using modified Poisson regressions controlling for grade retention, schooling, living out of parental household, socioeconomic status, and other substance (tobacco, cannabis, other illicit substances) use. Despite a steady decline in alcohol use among French adolescents over the past two decades, the prevalence of HED still concerned one, third of 17-year-olds in 2022. The reduction in alcohol use conceals an increased likelihood of HED among occasional drinkers (<10 times a month). Moreover, the probability of HED among females is similar to that of males, or even higher depending on the frequency of use. HED is becoming an increasingly common behavior among adolescent drinkers. The decline in prevalence conceals a homogenization of behavior between genders. Our results also question underage access to alcohol, despite increasing legal restrictions. These results support general prevention in early adolescence aimed at all drinkers, and not only at the most frequent or "at-risk" drinkers.

Does the decline in Swedish adolescent drinking persist into early adulthood?

Sweden has experienced a substantial decrease in adolescent drinking over the past decades. Whether the reduction persists into early adulthood remains unclear. Using survey data, the present study aimed to determine whether reductions in indicators of alcohol use observed among adolescents remain in early adulthood and whether changes in alcohol intake are consistent among light/moderate and heavy drinkers. Data from the Swedish monthly Alcohol Monitoring Survey (2001-20) were used to construct five 5-year birth cohorts (1978-82, 1983-87, 1988-92, 1993-97 and 1998-2002). Sweden. A total of n = 52 847 respondents (48% females) aged 16 and 30 years were included in this study. For both males and females, temporal changes in the prevalence of any drinking, the prevalence of heavy episodic drinking (HED) and total alcohol intake in the past 30 days in centilitres were analysed. The prevalence of any drinking in more recent cohorts remained low until young people came into their early (females) and mid- (males) 20s. Male cohorts differed in the prevalence of HED across age, with the later cohorts showing lower odds than earlier cohorts (odds ratios between 0.54 and 0.66). Among females, no systematic differences between cohorts across age could be observed. Later male birth cohorts in light/moderate drinkers had lower alcohol intake than earlier cohorts (correlation coefficients between -0.09 and -0.54). No statistically significant cohort effects were found for male heavy drinkers. Although differences in alcohol intake among females diminished as age increased, the cohorts did not differ systematically in their level of alcohol intake. In Sweden, the reduced uptake of drinking in adolescents appears to fade as people move into adulthood. Observed reductions in alcohol intake among light and moderate drinkers appear to persist into adulthood. More recent male cohorts show a lower prevalence rate of heavy episodic drinking.

Exploring the Association of e-Cigarette and/or Cannabis Use with Heavy Episodic Drinking among Ontario Adults

Background: The use of electronic cigarettes and cannabis has significantly increased in recent years, which raises public health concerns. There are also concerns about the association of these substances with drinking behaviors. The main objective of the present study is to examine the association of e-cigarettes and/or cannabis use with heavy episodic drinking (HED) among Ontario adults. Methods: The sample consisted of 5,564 adults from the Monitor Survey in 2018 and 2019. Cannabis and e-cigarette use reflected any use of the substances in the past 12 months. HED was defined as consumption of four/five or more drinks on a single occasion at least monthly in the past 12 months. Odds ratios (OR) were estimated from logistic regression models accounting for complex survey design and sociodemographic factors. Results: Overall, the prevalence of HED was 17.5% in 2018 and 2019. Among participants who reported both e-cigarette and cannabis use, about one-half (50.4%) reported HED at least monthly. Adjusting for covariates, the odds of HED were 5.71 (95%CI, 3.92–8.30) times higher among those who reported both e-cigarette and cannabis use compared to those who used neither substance. Conclusions: The use of e-cigarettes and cannabis are significantly associated with heavy episodic drinking among adults, indicating that those who engage in the dual use of e-cigarette and cannabis may be an important group to target with intervention programs.

Prevalence of heavy episodic drinking and alcohol use disorder diagnosis among US college students: Results from the national Healthy Minds Study

Alcohol use is a common, recognized problem on college campuses. This study examined alcohol use in a national sample of US college students across 78 campuses. Using four waves of data from the Healthy Minds Study (2015–2019), we explored variations by student demographics in prevalence of recent: alcohol consumption, heavy episodic drinking (HED, 4/5 + drinks in one sitting), frequent HED (3 + HED events), and lifetime alcohol use disorder (AUD) diagnosis. Stratified analyses and logistic regression with response propensity weights were used. Two-thirds of students consumed alcohol and roughly-one-third engaged in HED in the past 2 weeks. Alcohol use was more common among students who: identified as cis women/men, bisexual or gay/lesbian/queer, white non-Hispanic, lived in Greek housing or off-campus, were not first generation, or those not rating religion as important. Prevalence of HED among recent drinkers was high (56.7%) but varied by gender identity, race-ethnicity, living situation, and religiosity. In addition, higher HED prevalence was reported among: international, undergraduate, and underage (under 21) students. There was little variation in HED by sexual orientation identity or first generation status among recent drinkers. In a sub-sample of students engaging in frequent HED, AUD diagnosis was uncommon (1.4%) and less likely among students identifying as: cis women/men, heterosexual, racial-ethnic minorities (particularly Asian/Asian American or Pacific Islander), international, religious, or living in Greek housing. Alcohol use continues to be a part of college life, while screening and treatment remains rare. There are opportunities for improved programming and outreach acknowledging college student diversity.

Alcohol everywhere, anytime, coming to a world near you.

Nigeria ranks first for per capita consumption and heavy episodic drinking prevalence in Africa. Yet, there are no alcohol policies, standard drink measurements, or low-risk drinking guidelines (LRDG) in the country.This study explored the awareness and understanding/interpretations of the alcohol industry-sponsored ‘responsible drinking message’ (RDM) among Nigerian youth. Data were elicited through 53 semi-structured interviews and 3 focus groups (N=26), and we also observed product labels and industry websites.Undergraduate participants were aware of ‘‘drink responsibly’’ (one of the RDMs), but some out-of-school participants with low-level education did not know it existed. This is likely because drink responsibly message is promoted in English language without any indigenous language alternatives. It is embedded in conventional advertisements that glamorize drinking without stand-alone public health messages encouraging low-risk drinking behaviours. Participants shared divergent but subjective interpretations of drink responsibly, but none associated it with abstinence. Some associated drink responsibly with the ability to hold one's drink, stating that it means: ‘drinks very well, but don't get drunk’, and ‘drink to your satisfaction, but don't misbehave’. Other interpretations included: ‘know your limit’ and ‘drink in moderation'. Drink responsibly was also understood to mean ‘drink in excess but respect yourself’. Alcohol companies in Nigeria redirect consumers to Drinkaware's and DrinkIQ's websites in the UK but use inconspicuous fonts to inscribe ‘drink responsibly’ on product labels.By design, alcohol companies frame RDMs to promote drinking and individual responsibility. Thus, it engenders subjective interpretations, including high-risk drinking behaviours. Policymakers should jettison self-regulation, implement alcohol policies, and introduce LRDG to encourage low-risk drinking. Stand-alone public health interventions that promote abstinence or low-risk drinking behaviours should be developed, while Drinkaware's and DrinkIQ's websites should be avoided. To be effective, all RDMs should include the indigenous language versions.

Did COVID-19-Related Alcohol Sales Restrictions Reduce Alcohol Consumption? Findings from a National Online Survey in South Africa.

Background: South Africa has a high prevalence of heavy episodic drinking (HED). Due to the high levels of alcohol misuse and violence, public hospital intensive care units were often overrun during the COVID-19 pandemic. This research investigated alcohol intake behaviour change during differing levels of lockdown restrictions, which included bans on alcohol sales. Methods: A self-reported Facebook survey ran from July to November 2020. The questions included socio-demographics, income, alcohol intake, purchasing behaviour, and reasoning. Chi-square tests/Fisher’s exact test for categorical data, Student’s t-test for normal continuous data, and the Mann–Whitney U test for non-normal data were applied. Multiple logistic regression was run for HED versus moderate drinkers. Results: A total of 798 participants took part in the survey, of which 68.4% were female. Nearly 50% of participants fell into the HED category and the majority bought alcohol illegally during restrictions. HED respondents who drank more alcohol than usual during restrictions reported that they felt stressed, needed to relax, and were bored. Conclusions: Policies intended to increase the pricing of alcohol may have the potential to reduce alcohol intake. Reducing stress and anxiety may be key to curtailing HED during emergency situations.

Prevalence of heavy episodic drinking in the Brazilian adult population: National Health Survey 2013 and 2019.

To describe the prevalence of heavy episodic drinking in the Brazilian adult population, according to sociodemographic characteristics, in 2013 and in 2019. A cross-sectional study using data on heavy episodic drinking among adults (≥ 18 years) from the National Health Survey, analyzed descriptively. 60,202 participants were included in 2013 and 88,531 in 2019. The prevalence of heavy episodic drinking, in 2019 (17.1%; 95%CI 16.6;17.5), was higher than 2013 (13.1%; 95%CI 13.1;14.2). In the two years, there was a higher prevalence among male sex, adults 18 to 39 years old, individuals with high schooling and Black skin color. In addition, higher prevalence were found among residents in urban areas and in the Midwest and Southeast regions. The indication of the growing prevalence of alcohol abuse in Brazil and the differences in prevalence, according to sociodemographic characteristics, show the need to encourage public policies and actions to combat its use.

Heavy episodic drinking and HIV disclosure by HIV treatment status among People with HIV in IeDEA Cameroon.

Heavy alcohol use is common among people with HIV (PWH), leading to sub-optimal HIV care outcomes. Yet, heavy episodic drinking (HED) is not routinely addressed within most HIV clinics in sub-Saharan Africa. HIV disclosure may provide social support, potentially reducing HED to cope with HIV. We examined the prevalence of HED and HIV disclosure by antiretroviral treatment (ART) status among PWH receiving HIV care in Cameroon. We analyzed routine HIV clinical data augmented with systematic alcohol use data among adult PWH receiving HIV care in three regional hospitals from January 2016 to March 2020. Recent HED prevalence was examined across PWH by ART status: those not on ART, recent ART initiators (ART initiation ≤30 days prior), and ART users (ART initiation >30 days prior); and by gender. We used log-binomial regression to estimate prevalence differences (PD) between HIV disclosure and recent HED by ART status. Among 12,517 PWH in care, 16.4% (95%CI: 15.7, 17.0) reported recent HED. HED was reported among 21.2% (95%CI: 16.0, 26.3) of those not on ART, 24.5% (95%CI: 23.1, 26.0) of recent ART initiators, and 12.9% (95%CI: 12.2, 13.6) of ART users. Regardless of ART status, men were more likely than women to report HED. Those who disclosed HIV status had a lower HED prevalence than those who had not disclosed (aPD: -0.07; 95%CI: -0.10, -0.05) and not modified by gender. The prevalence of recent HED was high among PWH in care. HED prevalence was highest among men and recent ART initiators. Longitudinal analyses should explore how HIV disclosure may support PWH in reducing or abstaining from HED through social support. Systematic HED screening and referral to care should be included in routine HIV clinical care, particularly for men, to improve engagement in the HIV care continuum in Cameroon.

Country-Level Heavy Episodic Drinking and Individual-Level Experiences of Harm from Others’ Drinking-Related Aggression in 19 European Countries

Introduction: There is limited knowledge about how individual experiences of harm from others’ drinking are influenced by heavy episodic drinking (HED) at the country level. The present study aimed to assess (1) the association between the country-level prevalence of HED and the risk of experiencing harm from others’ drinking-related aggression and (2) if HED at the country level modifies the association between consumption of alcohol per capita (APC) and such harm. Methods: Outcome data from 32,576 participants from 19 European countries stem from the RARHA SEAS study. Self-reported harm from others’ drinking included having been verbally abused, harmed physically, or having serious arguments. Data on country-level drinking patterns were derived from the World Health Organization. Associations between country-level prevalence of monthly HED and experiences of aggression (at least 1 of 3 studied harms) were derived through multilevel models – adjusted for country-level age structure and by including the respondent’s own HED patterns as a mediator. Results: A 1% increase in the prevalence of monthly HED was associated with 5% higher odds (odds ratio [OR] 1.05) of experiencing others’ alcohol-related aggression among men, and 6% (OR 1.06) among women. The results suggest that the association between APC and harm was stronger in countries with high prevalences of HED, but the modifying effect could not be confirmed. Discussion/Conclusion: Harm from others’ drinking-related aggression depends not only on individual factors but is also influenced by the drinking patterns of the population. However, the country-level prevalence of HED only explains a small part of the variance of this type of harm.

At-risk drinking, operant demand, and cross-commodity discounting as predictors of drunk driving in underage college women

Behavioral economics offers unique tools for assessing value and motivation associated with college drinking. Tasks that model changes in consumption as a function of price (operant demand) or the decline in an outcome’s subjective value as a function of time-to-occurrence (delay discounting) provide valuable information that may efficiently supplement clinical screening instruments when characterizing alcohol use severity. The first aim of this investigation was to examine the extent to which at-risk drinking, operant demand for alcohol, and single- and cross-commodity discounting of money and alcohol predict adverse consequences of past-month drinking in underage college women (N = 72). The second aim was to determine whether these clinical and behavioral economic measures could significantly predict the odds of past-month drunk driving, a serious public health concern due to the increasing prevalence of heavy episodic drinking among women in their first 1 – 2 years of college. Results showed that higher scores on the consumption factor of the Alcohol Use Disorder Identification Test (AUDIT-C), higher Persistence (consumption amidst constraint) and Amplitude (maximum consumption) of demand, as well as lower rates of discounting for choices between alcohol now or double the amount after a delay (choosing the larger amount of alcohol even when it is delayed) significantly predicted adverse consequences of past-month drinking. Moreover, higher scores on the AUDIT-C, higher Amplitude of demand, and greater discounting for choices between alcohol now and money later (choosing immediately available alcohol at the expense of double the equivalent in delayed money) significantly predicted past-month drunk driving. We contend that operant demand along with single- and cross-commodity discounting can be viewed as intersecting measures of reinforcer value with clinical relevance to college women.

Association between age at first alcohol use and heavy episodic drinking: An analysis of Thailand's smoking and alcohol drinking behavior survey 2017.

According to evidence from developed countries, age at first alcohol use has been identified as a determinant of heavy episodic drinking (HED). This study aimed to investigate the association between age at first alcohol use and HED using data from the Smoking and Drinking Behavior Survey 2017, a Thai nationally representative survey. Binary logistic regression was used to examine the association. This study used data from 23,073 current drinkers in the survey. The survey participants were chosen to represent the Thai population aged 15 years and older. The prevalence of HED and frequent HED among Thai drinkers was 18.6% and 10.1%, respectively. Age at first drinking <20 years was associated with higher odds of HED (adjusted OR, 1.43; 95% CI, 1.26-1.62) and frequent HED (adjusted OR, 1.31; 95% CI, 1.12-1.53) relative to age at first drinking ≥25 years. Regular drinking, drinking at home, and exposure to alcohol advertising increased the odds of HED. Drinking at home was associated with frequent HED. There was a significant interaction between the effect of age at first alcohol use and sex on HED and frequent HED with a stronger effect of age at first alcohol use observed in females. This study provides evidence from a developing country that early onset of alcohol use is associated with HED. Effective measures such as tax and pricing policy should be enforced to delay the onset of drinking.

Can alcohol consumption in Germany be reduced by alcohol screening, brief intervention and referral to treatment in primary health care? Results of a simulation study.

Screening, brief intervention and referral to treatment (SBIRT) is a programme to reduce alcohol consumption for drinkers with high alcohol consumption levels. Only 2.9% of patients in primary health care (PHC) are screened for their alcohol use in Germany, despite high levels of alcohol consumption and attributable harm. We developed an open-access simulation model to estimate the impact of higher SBIRT delivery rates in German PHC settings on population-level alcohol consumption. A hypothetical population of drinkers and non-drinkers was simulated by sex, age, and educational status for the year 2009 based on survey and sales data. Risky drinking persons receiving BI or RT were sampled from this population based on screening coverage and other parameters. Running the simulation model for a ten-year period, drinking levels and heavy episodic drinking (HED) status were changed based on effect sizes from meta-analyses. In the baseline scenario of 2.9% screening coverage, 2.4% of the adult German population received a subsequent intervention between 2009 and 2018. If every second PHC patient would have been screened for alcohol use, 21% of adult residents in Germany would have received BI or RT by the end of the ten-year simulation period. In this scenario, population-level alcohol consumption would be 11% lower than it was in 2018, without any impact on HED prevalence. Screening coverage rates below 10% were not found to have a measurable effect on drinking levels. Large-scale implementation of SBIRT in PHC settings can yield substantial reductions of alcohol consumption in Germany. As high screening coverage rates may only be achievable in the long run, other effective alcohol policies are required to achieve short-term reduction of alcohol use and attributable harm in Germany. There is large potential to apply this open-access simulation model to other settings and for other alcohol interventions.

Socioeconomic inequalities in alcohol consumption in Argentina: Comparative analysis from 2009, 2013, and 2018

BackgroundThe present study investigates the socioeconomic inequalities in alcohol use and harmful drinking in Argentina, a middle-income beer- and wine-producing country with high levels of alcohol consumption. MethodsData from the last three waves (2009, 2013, and 2018) of the National Risk Factors Survey were used. Each wave comprised samples of 34,732, 32,365, and 29,224 individuals, respectively. Outcome measures included the prevalence of alcohol use and heavy episodic drinking (HED). The Erreygers concentration index was employed to measure the socioeconomic inequalities. ResultsHED prevalence among drinkers increased from 17 % in 2009 to 25 % in 2018. Overall, the results showed significant pro-rich inequality for alcohol use and pro-poor inequality for HED, indicating that while a smaller proportion of the most disadvantaged population consumed alcohol, harmful drinking tended to concentrate among them. Pro-rich inequality for alcohol use was deeper in the population aged 25+, particularly among women. HED among males aged 35+ showed the highest inequality against lower income groups. During the period analyzed, the group aged 18–24 years had the highest HED prevalence as well as the greatest increase in this measure; it tended to be equally distributed across socioeconomic groups, presenting no socioeconomic inequality by 2018. ConclusionsThese results highlight the importance of the assessment and characterization of the most exposed population to alcohol and harmful drinking. Regardless of their socioeconomic status, the young population was identified as a group for targeted interventions because of its greater alcohol exposure and the potential growth in economic and social burdens.

Alcohol and Mortality: An Actuarial Issue

Despite some favorable global trends in the prevalence of heavy episodic drinking, alcohol-related mortality and morbidity since 2010, and the prevalence of youth drinking in certain developed countries, there has been limited progress in reducing total per-capita alcohol consumption. The burden of disease attributable to alcohol remains high, particularly at pre-retirement ages, and is increasing in some countries and for some causes of death. This article describes the status and trends in alcohol consumption, both worldwide and in the United States. It also describes the adverse consequences of heavy and binge drinking, which are significant to the individual, family and friends, and society. Although the overall effect on mortality of moderate alcohol drinking compared with no drinking at all has generally been viewed to be somewhat favorable due to the effect of certain cardiovascular risks, this view is not shared by all—the arguments involved are examined in this article. The recognition and need for active management of the adverse effects of heavy and binge alcohol consumption, remain essential to favorable health and longevity. Possible public interventions are also described. Actuaries involved in assessing mortality trends and product design need to assess trends in drivers and consequences of historical, current, and expected future alcohol-attributable mortality and morbidity patterns on a regular basis.

Determinants and consequences of heavy episodic drinking among female sex workers in Ethiopia: A respondent-driven sampling study.

Female sex workers (FSW), due to their working conditions, have an increased likelihood of heavy episodic drinking (HED), which is associated with risky sexual behavior. Nevertheless the specific contribution of HED to risky sexual behavior among FSWs in Ethiopia is not well documented for prevention activities. The purpose of this study was to explore the determinants and consequences of HED among FSWs in Ethiopia. A cross-sectional study using respondent-driven sampling was conducted among 4886 FSWs in 11 major towns in Ethiopia in 2014. A structured interview was performed, and data were examined using descriptive statistics and multiple logistic regression analyses. Most (66%) FSWs consumed alcohol, and the prevalence of HED was 29.1%. Compared to street-based FSWs, those who worked in bars/hotels and local drinking houses had 2.19 and 1.29 times higher odds of HED, respectively. FSWs who started selling sex when younger than 18 years (compared to those who started when older than 25 years) and those who were forced into selling sex had 1.48 and 2.91 times higher odds of HED, respectively. FSWs with more income from selling sex and FSWs who chewed khat reported increased odds of HED. Moreover, FSWs with experience of HED reported 1.27 and 1.44 times higher odds of physical beating and condom breakage/slippage, respectively. Furthermore, the population attributable risk fraction of HED among FSWs showed that 6.2% of physical beating and 8.9% of condom breakage/slippage could be attributed to HED. In general, several factors increase the experience of HED, and HED in turn increases the likelihood of violence and condom breakage. These factors could inform programs and intervention activities among FSWs populations.

Alcohol Consumption among Freshman College Students in Spain: Individual and Pooled Analyses of Three Cross-Sectional Surveys (2005, 2012 and 2016).

Objective: We aimed to evaluate changes in the prevalence of Heavy Episodic Drinking (HED) and Risky Consumption (RC) in freshman college students between 2005, 2012 and 2016; and to identify the explanatory variables of these patterns of consumption using individual and pooled analyses. Methods: A cross-sectional study involving 5260 students was carried out in Spain in 2005, 2012 and 2016. HED and RC were determined using the Alcohol Use Disorders Identification Test. Another questionnaire was used to measure parental education level and alcohol use, alcohol-related problems, age of onset of alcohol use and alcohol-related expectancies. Adjusted Odds Ratios (ORs) of RC and HED and their 95% Confidence Intervals were estimated using logistic regression. Results: An increase in the prevalence rates of HED and RC was observed among women during the three-study periods, nonetheless there was no statistically significant difference in the prevalence rates among men. High maternal educational level, living away from parental home, initiating drinking before the age of 15 and having positive expectancies about drinking are associated with higher prevalence of RC in both genders. High positive expectancies and early onset of alcohol use are associated with higher rates of HED among men and women. Students recruited in 2012 and 2016 are protected against RC in comparison to those recruited in 2005. Conclusions: The age of alcohol consumption onset is the most influencing factor on HED and RC for both genders in the three-study periods. Alcohol prevention campaigns targeting youth at early ages can reduce risky drinking behaviors.

Calendar Month Variation in Alcohol and Marijuana Use in a Community Sample of Young Adults

Alcohol use among adults varies by season, and drinking among 4-year college students has been linked to holidays and the academic calendar. Little research has assessed calendar-related variation in marijuana use. We examined calendar month variation in alcohol and marijuana use among a sample of young adults that was diverse with respect to college status and educational attainment. Data were drawn from a community sample of 761 individuals (57% female; ages 18-23 at enrollment). Participants were surveyed monthly for 24 consecutive months. Multilevel models accounted for nesting of monthly data within individuals. All measures of substance use showed evidence of variation by calendar month, with the exception of hours high in months when marijuana was used. Drinks per week and peak number of drinks were relatively elevated in summer months and in October and December; the prevalence of heavy episodic drinking was also elevated in October and December. Attending a 4-year college was associated with more drinking than not being enrolled in a 4-year college, regardless of whether a 4-year degree had been obtained. Students in a 4-year college reported more drinks per week than those not in a 4-year college in September and October, whereas the peak number of drinks converged across educational status in the summer months and in December. Across educational statuses, marijuana use was highest in April and December. Findings may guide the targeting and timing of substance use prevention programs by focusing efforts before and during higher risk months.

Is the theory of collectivity of drinking cultures valid across educational groups?

IntroductionTo explore whether Skog's theory of collectivity of drinking cultures is valid across groups with different socioeconomic position (SEP).MethodsIndividual‐level information on alcohol consumption and SEP for the years 2004–2014 were retrieved from the Monitoring Project; a nationally representative monthly alcohol use survey. The analytical sample consisted of 162 369 respondents aged 25–79 years. SEP was measured by education level. Alcohol use was measured by yearly volume of consumption and frequency of heavy episodic drinking (HED). Respondents were divided into six SEP‐groups based on their education level and sex. Mean yearly volume consumption and prevalence of monthly HED was calculated for each group and graphically plotted against the overall mean volume of consumption.ResultsThe yearly changes in overall mean consumption during the study period reflected a collective shift in drinking across groups with basic, intermediate and high education. There were also indications that changes in overall mean consumption reflected collective shifts in the prevalence of HED across the SEP‐groups. Moreover, while the magnitude of the associations for both average volume and HED differed somewhat in strength across the SEP‐groups, they were clearly in the same, positive, direction.Discussion and ConclusionsOur findings add support for including a socioeconomic dimension to Skog's theory of collectivity of drinking cultures. Future studies should replicate our analyses on cases and periods with more tangible changes in the price and availability of alcohol.
