Adolescents drink less: How, who and why? A review of the recent research literature

Historic and current achievements of the temperance movement in the control of alcohol and its adverse health consequences

SETTING

The study aims to assess firstly, the historical (pre-2000) achievements in the control of alcohol and its adverse health consequences in the nine developed countries with mass temperance movements. Currently (post-2000), it looks at achievements in developed countries more generally, including these nine countries.

METHODS

The study is a policy analysis conducted within an historical timeframe. This principally involves the historical impacts on government schemes regulating alcohol as well as individual alcohol consumption and its consequences. Trends since 2000 in alcohol consumption in young people in high-income temperance cultures are also examined.

RESULTS AND CONCLUSION

Substantial alcohol-related public health impacts have occurred in almost all of the nine countries, either on relevant government schemes and/or individual alcohol consumption. Regarding government schemes, five of the nine temperance countries, and in part a sixth (the US), retain government store monopoly systems, offering heavily-taxed spirits with limits on their accessibility. Impacts on individual consumption in these countries, where studied, were positive. Consumption in young people since 2000 in high income countries is lower in temperance than non-temperance countries. It is concluded that temperance culture has had substantial and enduring governmental and individual public health impacts relating to alcohol consumption.

International trends in male youth suicide and suicidal behaviour

OBJECTIVE

Suicide and suicidal behaviour strongly contribute to overall male youth mortality. An understanding of worldwide data contextualises suicide and suicidal behaviour in young men within any given country.

METHOD

Members and colleagues of the World Federation of Societies of Biological Psychiatry's Task Force on Men's Mental Health review the relevant data from several regions of the world. The review identifies notable findings across regions of relevance to researchers, policymakers, and clinicians.

RESULTS

Male suicide and suicidal behaviour in adolescence and emerging adulthood within North America, Latin America and the Caribbean, Europe, the Mediterranean and the Middle East, Continental Africa, South Asia, East Asia, China, and Oceania share similarities as well as significant points of divergence.

CONCLUSIONS

International data provide an opportunity to obtain a superior understanding of suicide and suicidal behaviour amongst young men.

Depressive symptoms, conduct problems and alcohol use from age 13 to 19 in Norway: evidence from the MyLife longitudinal study

BACKGROUND

Even though mental health problems and alcohol use remain major challenges facing adolescents, our understanding of their developmental progressions primarily stems from cohorts coming 1 of age in the early 2000's. We aimed to examine and describe normative developmental trajectories of depression, conduct problems, and alcohol use across adolescent years among more recent cohorts of Norwegian youth born in the 21st century.

METHODS

Multilevel mixed linear models for symptoms of depression and conduct disorder, and multilevel mixed logistic models for depressive disorder, conduct problems, any alcohol use, and risky drinking, were estimated with longitudinal data from a nationwide sample N = 3436 (55% girls) of Norwegian adolescents (mean age 14.3 [SD = 0.85] in 2017). We compared models with linear, quadratic, and cubic change with age, and models that tested moderation by sex and centrality (rural vs. urban communities).

RESULTS

Average symptoms and the rate of depressive disorder increased sharply from age 13 to age 19, but both the initial levels and the rates of change were greater for girls than for boys. Average symptoms of conduct disorder and the rate of conduct problems increased in early adolescence and were greater for boys than girls. The rates of any alcohol use and risky drinking both increased sharply from age 14, but there were no notable sex differences either in the initial levels or rates of change over time. Adolescents from more rural communities had greater rates of any drinking in mid-adolescence, but there were no other effects of centrality.

CONCLUSIONS

This study provides a much-needed update concerning normative developmental trajectories of depression, conduct problems, and alcohol use among millennium cohorts. Consistent with prior studies, we observed significant increases in all outcomes across adolescence, with depression being both greater and more prevalent among girls and conduct problems being both greater and more prevalent among boys. Consistent with the emerging evidence, we observed no sex differences in alcohol use. Finally, there were no differences in the examined developmental trajectories as a function of centrality. These findings underscore the importance of early prevention and treatment of mental health and substance use problems.

Diverging trends in alcohol use and mental health in Australian adolescents: A cross-cohort comparison of trends in co-occurrence

Background

In recent years, psychological distress in Western countries has rapidly increased among older adolescents while alcohol use has declined, though little is known about younger adolescents. It is also unclear if and how these trends relate to co-occurring alcohol use and distress. This study sought to examine temporal changes in the prevalence of distress, alcohol use, and their co-occurrence among young Australians.

Methods

This study used data from 13,388 youth in their early teens (aged 12-14). Differences in the prevalence of high psychological distress (Kessler-6 ≥ 13), any alcohol use (standard drink in past 3/6 months), and their co-occurrence across cohorts (2007, 2012, 2014, 2019) were tested through log-binomial regression models. Changes in co-occurrence across cohorts were tested with cohort-by-alcohol interactions predicting distress, and vice-versa. Differential trends by sex were evaluated.

Results

From 2007 to 2019, the prevalence of high distress more than doubled (4.6%-13.5%) while alcohol use decreased by ∼90% (11.8%-3.1%). Distress increased more-so among females, while alcohol use decreased more-so among males. The prevalence of high distress was significantly greater among adolescents who used alcohol compared to those who had not (>2 times higher), with this co-occurrence remaining consistent across cohorts.

Conclusions

Psychological distress appears to be increasing similarly among youth in their early teens who do and do not use alcohol. At the same time, alcohol use is decreasing similarly among youth with and without distress. While alcohol use does not appear to be a driver of increases in distress, rates of co-occurring alcohol use and distress remain high. Addressing co-occurrence and distress-specific mechanisms remain necessary.

Modeling of drinking and driving behaviors among adolescents and young adults in the United States: Complexities and Intervention outcomes

Alcohol-impaired driving is a formidable public health problem in the United States, claiming the lives of 37 individuals daily in alcohol-related crashes. Alcohol-impaired driving is affected by a multitude of interconnected factors, coupled with long delays between stakeholders' actions and their impacts, which not only complicate policy-making but also increase the likelihood of unintended consequences. We developed a system dynamics simulation model of drinking and driving behaviors among adolescents and young adults. This was achieved through group model building sessions with a team of multidisciplinary subject matter experts, and a focused literature review. The model was calibrated with data series from multiple sources and replicated the historical trends for male and female individuals aged 15 to 24 from 1982 to 2020. We simulated the model under different scenarios to examine the impact of a wide range of interventions on alcohol-related crash fatalities. We found that interventions vary in terms of their effectiveness in reducing alcohol-related crash fatalities. In addition, although some interventions reduce alcohol-related crash fatalities, some may increase the number of drinkers who drive after drinking. Based on insights from simulation experiments, we combined three interventions and found that the combined strategy may reduce alcohol-related crash fatalities significantly without increasing the number of alcohol-impaired drivers on US roads. Nevertheless, related fatalities plateau over time despite the combined interventions, underscoring the need for new interventions for a sustained decline in alcohol-related crash deaths beyond a few decades. Finally, through model calibration we estimated time delays between actions and their consequences in the system which provide insights for policymakers and activists when designing strategies to reduce alcohol-related crash fatalities.

Implications of the decline in adolescent drinking on the experience of alcohol-related consequences in the Nordic countries: A study based on data from the ESPAD project

Aims: The aim of this study was to investigate: (1) whether self-reported acute alcohol-related consequences among adolescents in the Nordic countries have declined in concert with the decline in alcohol consumption; (2) whether the relationship between alcohol consumption and alcohol-related consequences has strengthened; and (3) whether the decline in alcohol-related consequences can be attributed to the decline in alcohol consumption. Methods: Data are from the European School Survey Project on Alcohol and Other Drugs (ESPAD) cross-sectional surveys in 2007, 2011 and 2015. Participants were students aged 15-16 years in 2007 (n = 16,035), 2011 (n = 14,765) and 2015 (n = 13,517). Alcohol consumption variables included lifetime and 12-month alcohol use, volume ethanol at last drinking occasion and heavy episodic drinking in the past 30 days. Self-reported acute alcohol-related consequences were measured as a sum index of experiencing the following at least once within the last 12 months: (1) an accident or injury; (2) being victimised by robbery or theft; or (3) had trouble with the police. Results: For all alcohol indicators, adolescent alcohol use decreased between 2007 and 2015. The highest prevalence estimates were found in Denmark, and here only the number of current drinkers decreased significantly. In addition, a decreasing trend in self-reported acute alcohol-related consequences was observed. We did not find a strengthening of the alcohol consumption consequences association from 2007 to 2015, except in Iceland. When all surveys were combined, the decrease in alcohol-related consequences could be explained by a decrease in alcohol consumption. Conclusions: Overall, adolescents aged 15-16 years exhibited decreasing trends in both alcohol consumption, less markedly in Denmark, and in our sum index of alcohol-related consequences between 2007 and 2015. Except for Iceland, we found no support for a strengthening of the alcohol-consequences association with declining drinking among adolescents.

Mind the gap! Gender differences in alcohol consumption among Swedish ninth graders 1989-2021

INTRODUCTION

To examine gender differences in drinking habits among Swedish ninth graders over the period 1989-2021.

METHODS

Annual school surveys with nationally representative samples of ninth-grade students in Sweden covering the period 1989-2021, total sample of 180,538 students. Drinking habits were measured with self-reports of frequency and quantity of use and frequency of heavy episodic drinking. Differences between genders were compared annually and differences were tested using logistic and ordinary least square regression models with cluster robust standard errors.

RESULTS

Small gender differences in the prevalence of alcohol use during the first part of the study period were followed by an increasing gap over the past decade with girls being more likely to drink alcohol than boys. Boys consumed larger amounts of alcohol than girls during the first three decades of the studied period but no gender differences were found in later years. Binge drinking was more prevalent among boys during 1989 to 2000 but no systematic gender difference was found during the past 15 years.

DISCUSSION AND CONCLUSIONS

There used to be clear gender differences in drinking habits among ninth graders in Sweden with boys drinking more than girls. This gap has narrowed over the past three decades and among contemporary adolescents, no gender differences are found neither in binge drinking nor volume of drinking and the prevalence of drinking is even higher among girls.

Changes in co-use of alcohol and cannabis among Nordic adolescents in the 21st century: Results from the European School Survey Project on Alcohol and Other Drugs study

INTRODUCTION

In the 21st century, there has been a decline in alcohol use among adolescents in most Nordic countries, while trends of cannabis use have diverged. We explore how alcohol and cannabis use, respectively, and co-use of the two substances, have changed among Nordic adolescents. Three hypotheses are used to frame the study: (i) cannabis use has substituted alcohol use; (ii) there has been a parallel decline in both substances; and/or (iii) there has been a 'hardening' of users, implying that alcohol users increasingly use cannabis.

METHODS

Data from the European School Survey Project on Alcohol and Other Drugs, conducted among 15- to 16-year-olds in Denmark, Finland, Iceland, Norway and Sweden (N = 74,700, 49% boys), were used to explore trends of past-year alcohol and cannabis use in the period 2003-2019.

RESULTS

The proportion of adolescents reporting alcohol use decreased significantly in all Nordic countries except Denmark. The proportion of those using cannabis only was low (0.0%-0.7%) and stable in all countries. The total number of substance use occasions declined among all adolescents in all countries but Denmark. Among alcohol users, cannabis use became increasingly prevalent in all countries but Denmark.

DISCUSSION AND CONCLUSIONS

We found no support for the 'parallel decline hypothesis' in alcohol and cannabis use among Nordic adolescents. Partially in line with the 'substitution hypothesis', cannabis use accounted for an increasing proportion of all substance use occasions. Our results suggests that the co-use of alcohol and cannabis has become more common, thus also providing support to the 'hardening' hypothesis.

Psychosocial correlates of drinking transitions: A longitudinal study among adolescents in Sweden

INTRODUCTION

Non-drinkers have been shown in older studies to have poorer mental health and social life compared to their alcohol-using counterparts. Given the profound decline in adolescent drinking observed in most high-income countries, this pattern may have changed. This study explores drinking transitions and examines psychosocial factors among adolescents by longitudinal drinking status.

METHODS

Data were based on two waves of a prospective longitudinal nationwide study (n = 4018). The first wave (T1) of data was collected in 2017 (age 15/16) and the second wave (T2) was in 2019 (age 17/18). Respondents were asked about their past year drinking status, general health, psychosomatic problems, psychiatric medication, school enjoyment, emotional symptoms, peer relationship problems, prosocial ability, friendships satisfaction and satisfaction with relation to mother/father. Comparisons by mean values were assessed and multinomial logistic regressions were used to examine associations.

RESULTS

Abstainers and later drinkers differed significantly from early drinkers on 9/10 factors respectively at T1. Fewer psychosomatic problems, less psychiatric medication, higher school enjoyment, more emotional symptoms, higher parental relationship satisfaction, more peer problems and lower friendships satisfaction at T1 were associated with abstaining and/or later drinking. All factors were more strongly associated with abstaining. School enjoyment predicted abstaining but not later drinking.

DISCUSSION AND CONCLUSIONS

Longitudinal drinking status relates to small to moderate systematic psychosocial differences. Adolescents with better mental health, more content relationships with parents and lower friendships satisfaction are more often abstainers. Those generally worse off are more likely early drinkers but they also have better friendships.

Understanding youth drinking decline: Similarity and change in the function and social meaning of alcohol use (and non-use) in adolescent cohorts 20 years apart

INTRODUCTION

Qualitative research aimed at understanding the decline in youth drinking has so far been hampered by a lack of baseline data for comparison. This New Zealand study overcomes this limitation by comparing archival qualitative data collected at the height of youth drinking (1999-2001) with contemporary data collected for this study (June-October 2022). The aim is to explore changes in the function and social meaning of alcohol use (and non-use) for two cohorts about 20 years apart.

METHODS

Both archival and contemporary data were collected from 14 to 17 year old secondary school students (years 10-12) through individual and small-group/pair interviews in matched suburban co-ed schools. Interviews explored friendships, lifestyles, romantic relationships and experiences and perceptions of substance use and non-use.

RESULTS AND DISCUSSION

Comparative analysis highlighted changes that may help to explain the decline in youth drinking, including an increased value placed on personal choice and acceptance of diversity; decreased face-to-face socialising and the emergence of social media as a central feature of adolescent social life, perhaps displacing key functions of drinking and partying; increased pervasiveness of risk discourses and increased awareness of health and social risks of alcohol; and increased framing of alcohol use as a coping mechanism by both drinkers and non-drinkers.

CONCLUSIONS

Collectively, these changes appear to have shifted the social position of drinking from an almost compulsory component of adolescent social life in 1999-2001, to an optional activity that many contemporary adolescents perceive to have high risks and few benefits.

Global Trends in the Prevalence of Alcohol Consumption Among School-Going Adolescents Aged 12-15 Years

PURPOSE

Adolescent alcohol consumption is detrimental to multiple facets of health. However, there is a scarcity of data available on time trends in adolescents' alcohol consumption particularly from non-Western countries and low- and middle-income countries. Thus, we examined the temporal trend of alcohol use in a large representative sample of school-going adolescents aged 12-15 years from 22 countries in Africa, Asia, and the Americas.

METHODS

Data from the Global School-based Student Health Survey were analyzed. Alcohol consumption referred to consuming alcohol on at least one day in the past 30 days. Crude linear trends of past 30-day alcohol consumption by country were assessed by linear regression models.

RESULTS

Data on 135,426 adolescents aged 12-15 years were analyzed [mean (standard deviation) age 13.8 (1.0) years; 52.0% females]. The overall mean prevalence of past 30-day alcohol consumption was 14.1%. Of the 22 countries included in the study, increasing, decreasing, and stable trends were observed in 3, 8, and 11 countries, respectively. Specifically, significant increases were observed in Benin between 2009 (16.1%) and 2016 (38.6%), Myanmar between 2007 (0.9%) and 2016 (3.6%), and Vanuatu between 2011 (7.6%) and 2016 (12.2%). The most drastic decrease was observed in Samoa between 2011 (34.5%) and 2017 (9.8%), but the rate of decrease was modest in most countries.

DISCUSSION

Among school-going adolescents, decreasing trends in alcohol consumption were more common than increasing trends, but the rate of decrease was limited in most countries, suggesting that more global action is required to curb adolescent alcohol consumption.

Geographies of alcohol and generation: Examining the decline in youth drinking in England through a spatial lens

INTRODUCTION

While international literature addresses the links between youth culture and the decline in youth drinking, little research has engaged with scholarship on youth geographies to more fully disentangle these links. This article explores how the decline is connected to shifts in where young people access and drink alcohol.

METHODS

Qualitative interviews were conducted with young people aged 12-19 (N = 96) and 29-35 (N = 17) years in England. The interviews explored the place of alcohol in everyday life, with younger participants discussing the present and older participants discussing their youth in the late 1990s to early 2000s. Data were analysed thematically.

FINDINGS

Buying alcohol in shops and licensed premises was a common experience for older participants when they were teenagers but few younger participants discussed buying alcohol from commercial settings. Older participants also reflected positively on drinking in outdoor public spaces whereas younger participants, particularly those from working-class backgrounds, regarded this as morally suspect. Young participants instead accessed alcohol from parents and siblings, and often consumed it in their or others' homes in supervised or moderated ways, seeing this as positive and normative.

DISCUSSION AND CONCLUSION

Spatial shifts in young people's drinking away from public spaces and toward the home appear an important part of a wider trend that renders youth drinking as increasingly moderate, risk-averse, incidental and mediated by parents, rather than excessive, transgressive and integral to youth culture.

Trends in alcohol-related harm among Swedish youth: Do in-patient care registry data match drinking trends?

INTRODUCTION

Youth drinking has been declining in Sweden since the year 2000. There is a paucity of studies examining trends in alcohol-related harm during this period. The overall aim of the present study is to examine how trends in alcohol-related harm match trends in drinking among Swedish youths during 2000-2021.

METHODS

Measures of alcohol use were obtained from national school surveys. Prevalence rates of any alcohol use and heavy episodic drinking were used. Alcohol-related harm indicators were obtained from registry information from the National Board of Health and Welfare. Annual trends in harm indicators were tested with linear regression models and correlations between alcohol use and alcohol-related harm indicators were assessed using Pearson's correlation on annual data.

RESULTS

Statistically significant negative trends were observed for all alcohol-related harm indicators for the period 2000-2021. Significant correlations were found for both measures of alcohol use and all alcohol-related harm indicators.

DISCUSSION AND CONCLUSIONS

The levels of alcohol-related harm have declined among youths in Sweden during the period 2000-2021. The trends in harm seem to reflect the decline in youth drinking that has occurred during the same period.

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

BACKGROUND AND AIMS

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.

DESIGN

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).

SETTING

Sweden.

PARTICIPANTS

A total of n = 52 847 respondents (48% females) aged 16 and 30 years were included in this study.

MEASUREMENTS

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.

FINDINGS

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.

CONCLUSIONS

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.

Cannabidiol tempers alcohol intake and neuroendocrine and behavioural correlates in alcohol binge drinking adolescent rats. Focus on calcitonin gene-related peptide's brain levels

Alcohol binge drinking is common among adolescents and may challenge the signalling systems that process affective stimuli, including calcitonin gene-related peptide (CGRP) signalling. Here, we employed a rat model of adolescent binge drinking to evaluate reward-, social- and aversion-related behaviour, glucocorticoid output and CGRP levels in affect-related brain regions. As a potential rescue, the effect of the phytocannabinoid cannabidiol was explored. Adolescent male rats underwent the intermittent 20% alcohol two-bottle choice paradigm; at the binge day (BD) and the 24 h withdrawal day (WD), we assessed CGRP expression in medial prefrontal cortex (mPFC), nucleus accumbens (NAc), amygdala, hypothalamus and brainstem; in addition, we evaluated sucrose preference, social motivation and drive, nociceptive response, and serum corticosterone levels. Cannabidiol (40 mg/kg, i.p.) was administered before each drinking session, and its effect was measured on the above-mentioned readouts. At BD and WD, rats displayed decreased CGRP expression in mPFC, NAc and amygdala; increased CGRP levels in the brainstem; increased response to rewarding- and nociceptive stimuli and decreased social drive; reduced serum corticosterone levels. Cannabidiol reduced alcohol consumption and preference; normalised the abnormal corticolimbic CGRP expression, and the reward and aversion-related hyper-responsivity, as well as glucocorticoid levels in alcohol binge-like drinking rats. Overall, CGRP can represent both a mediator and a target of alcohol binge-like drinking and provides a further piece in the intricate puzzle of alcohol-induced behavioural and neuroendocrine sequelae. CBD shows promising effects in limiting adolescent alcohol binge drinking and rebalancing the bio-behavioural abnormalities.

"I don't want to introduce it into new places in my life": The marketing and consumption of no and low alcohol drinks

INTRODUCTION

Recent years have seen an expanding 'no and low alcohol' (NoLo) drinks market in the United Kingdom and other high-income countries. With the UK government pledging to increase the availability of NoLos and encourage their consumption, further research is required to underpin policy and explore the potential for NoLos to ease - or exacerbate - alcohol-related harm.

METHODS

This paper draws on original primary research on NoLo marketing and consumption in the UK; analysis of two NoLo marketing campaigns and semi-structured interviews with both drinkers and non-drinkers who consume NoLos.

FINDINGS AND DISCUSSION

Addition marketing was identified in the promotion of NoLo products, encouraging consumers to incorporate NoLo consumption into new spatial and temporal contexts on top of their typical weekly drinking patterns. However, there was resistance towards these practices from consumers, who stressed they were more likely to drink NoLos in place of alcohol and incorporate them into their existing drinking routines.

CONCLUSION

This paper expands a currently very limited evidence base and contributes directly to ongoing debates around 'addition' versus 'substitution' (i.e. whether NoLo products are being used on top of or in place of alcohol). Findings highlight both some of the challenges and opportunities of the expanding market, pointing towards the problematic presence of 'addition marketing' but also highlighting the ways consumers might challenge this and use NoLos flexibly to reduce consumption. As a result, NoLo promotion could function as one tool amongst many to help at least some consumers drink in moderation, alongside a broader package of measures such as education and wider social change.

Adolescent binge-like alcohol exposure dysregulates NPY and CGRP in rats: Behavioural and immunochemical evidence

Alcohol binge drinking during adolescence impacts affective behaviour, possibly impinging on developing neural substrates processing affective states, including calcitonin gene-related peptide (CGRP) and neuropeptide Y (NPY). Here, we modelled binge-like alcohol exposure in adolescence, by administering 3.5 g/kg alcohol per os, within 1 h, to male adolescent rats every other day, from postnatal day 35 to 54. The effects on positive and negative affective behaviour during abstinence were explored including: consummatory behaviour and weight gain; social behaviour in the modified social interaction test; thermal nociception in the tail-flick test; psychosocial stress coping in the resident-intruder paradigm. Moreover, CGRP and NPY levels were evaluated in functionally relevant brain regions. Our data shows that binge-like intermittent alcohol administration during adolescence decreased weight gain, social preference and motivation, nociception, and active psychosocial stress coping during abstinence. In addition, intermittent alcohol-exposed rats displayed increased expression of CGRP and NPY in the prefrontal cortex and nucleus accumbens; decreased NPY levels in the amygdala; opposite changes in CGRP levels in the hypothalamus and brainstem. Overall, our data shows that adolescent binge-like alcohol exposure, through the allostatic load of alternate intoxication and withdrawal, produces long-term consequences in sensory and affective processes and dysregulated complementary neuropeptidergic systems. Thus, neuropeptide-targeted interventions hold promising potential for addressing negative affect during prolonged withdrawal in young subjects.

Trends in Tobacco Use among 9th Graders in Sweden, 1991-2020

Tobacco use was measured with self-reports of lifetime use of cigarettes and snus to examine trends in tobacco use among Swedish 9th graders over the period 1991-2020. Annual school surveys with nationally representative samples of 9th-grade students in Sweden covering the period 1991-2020 with a total sample of 163,617 students. We distinguished between the use of cigarettes only, use of snus only, dual use (use of both cigarettes and snus), and total tobacco use (use of any of these tobacco products). In addition to a graphical description of trends in the various measures of tobacco use, the correlation between these trends was calculated with the Pearson correlation coefficient (Rxy). The prevalence of total tobacco use declined from 72% in 1991 to 36% in 2020. The declining trend in total tobacco use was positively correlated with the trend in dual use (Rxy = 0.98) and the trend in cigarette use only (Rxy = 0.87). The trend in total tobacco use was, on the other hand, negatively correlated with snus use only (Rxy = -0.41), and snus use only was negatively correlated with cigarette use only (Rxy = -0.71). The situation became different after 2017 when total tobacco use increased as a result of an increasing prevalence of snus use. The sharp decline in tobacco use among 9th graders in Sweden over the past three decades is driven by declining cigarette use. The correlations between the various forms of tobacco use suggest that snus use may have contributed to the decline in cigarette use and, by that, overall tobacco use. The situation changed after 2017 when a sharp rise in snus use seems to have increased total tobacco use among adolescents in Sweden. A possible explanation behind this development is the introduction of a new form of snus called "All white snus", which was introduced in Sweden in 2014.

'When I came to university, that's when the real shift came': alcohol and belonging in English higher education

While young people's alcohol consumption has fallen sharply in the United Kingdom and other high-income countries, universities remain places where heavy drinking is routine and normative. Drawing on interviews with undergraduate students, this article explores how heavy drinking is part of how students negotiate a sense of belonging and form personal relationships. Theoretical work on belonging and relationality is used to make sense of students' encounters with alcohol. Consistent with the decline in youth drinking, several interviewees had limited experience of heavy drinking prior to university, and some were not interested in taking it up. After describing how heavy drinking facilitates belonging in certain spaces of student life, we examine the strategies of non- and low-drinking students in navigating these spaces. Attending to their strategies suggests that becoming known as 'social persons' is key to negotiating belonging without drinking heavily. We conclude by considering how universities might better accommodate the desire for belonging for the increasingly large proportion of students with limited experience of or desire for alcohol by creating opportunities for students to form personal relationships in ways that do not involve alcohol or where alcohol is peripheral to the activity.

Abstainers and Drinkers - Two Sides of the Same Coin?

This commentary discusses a recently published literature review focussing on the growing trend of young people abstaining from drinking alcohol. Despite the recent increase in research on the decline in youth drinking, the review only identified 10 papers that explicitly examined abstainers. The inclusion criteria used thus excluded and overlooked the vast literature available on the decline in youth drinking. This commentary discusses the implications of this and raises the issue of how the adolescent abstainer should be viewed in research; is it a distinct social phenomenon with unique determinants or are abstainers merely the flip side of drinkers?

Decline in youth drinking in high-income settings: Implications for public health in low-income countries

Declining drinking among youth in many high-income countries has attracted scholarly attention and debates. Still, researchers are yet to globalize such research or examine its public health implications for low-resource settings. This commentary has two interrelated purposes. First, using evidence from Nigeria, it highlights how declining youth drinking in high-income countries may impact public health in low-income countries. Second, it highlights the necessity for research to examine youth drinking behaviours simultaneously worldwide. The declining drinking trends among young people in high-income countries have occurred simultaneously with global alcohol corporations being more aggressive in low-income countries like Nigeria. Relatedly, alcohol corporations may employ evidence regarding declines in drinking to argue against implementing stringent policies or other effective interventions in Nigeria (and other low-income settings), claiming their apparent success in the falling drinking trends in high-income settings. The article argues that research on the drinking decline among young people should be globalized because without commensurate attempts to examine their drinking behaviours/trends worldwide simultaneously, public and/or global health may be harmed for the reasons explored in this article.

Ambivalence in Adolescents’ Alcohol Expectancies: A Longitudinal Mixed Methods Study Among 12-to-18-Year-Olds

Drawing on the framework of alcohol expectancies and their importance for drinking behaviors, this longitudinal mixed-methods study examined changes and continuities in development of alcohol expectancies during adolescence. Quantitative and qualitative data were prospectively collected at four time points between 2015 and 2020 from nationwide, socio-economic, and gender-balanced samples of Norwegian adolescents aged 12–18. Quantitative data ( n = 3425) were analyzed using linear mixed-effects models, and qualitative data ( nT1 = 118) using thematic analysis. Quantitative and qualitative results were juxtaposed in the discussion. Quantitative results indicated an increase in social facilitation and tension reduction expectancies from age 13 to 18, and a simultaneous decrease in negative emotional expectancies. This development could partly be explained by experience with alcohol use in adolescence. Similarly, qualitative findings showed adolescents’ expectancies of alcohol evolving with age; from one-sided negative expectancies of aggression and harm to increased positive expectancies of fun, sociability, and relaxation. Both analyses showed that negative expectances remained high throughout the study period, but by late adolescence, many participants held positive and negative expectations simultaneously. The qualitative data illustrated how adolescents’ alcohol expectancies became increasingly ambivalent and complex with age, as alcohol use became more common. Prevention strategies aiming to reduce underage alcohol use should acknowledge this complexity.

Generational shifts in attitudes and beliefs about alcohol: An age-period-cohort approach

INTRODUCTION AND AIMS

Population level alcohol consumption has declined markedly in Australia in the past two decades, with distinct generational patterns. The underlying reason for this shift remains unclear and there has been little work assessing how attitudes and beliefs about alcohol have shifted in population sub-groups.

DESIGN AND METHODS

Using seven waves of survey data spanning 19 years (2001-2019, n = 166,093 respondents aged 14 +), we assess age, time-period and birth cohort effects on trends in four measures of alcohol attitudes (disapproval of regular alcohol use, perceptions of safe drinking levels for men and women and perception that alcohol causes the most deaths of any drug in Australia).

RESULTS

There were steady increases in period effects for perceived safe drinking levels (especially for men) and belief that alcohol causes the most deaths. Disapproval of regular use has been stable at the population level, but there are marked cohort differences, with early and recent cohorts more likely than others to disapprove of regular alcohol use.

DISCUSSIONS AND CONCLUSIONS

These findings point to a broad lowering of perceived safe levels of drinking across the population alongside a sharp increase in disapproval of drinking for recent cohorts, potentially contributing to the reductions in drinking that have been reported in these cohorts.

Preventing alcohol use among Hispanic adolescents through a family-based intervention: The role of parent alcohol misuse

Early-life alcohol use raises the risk of poor long-term alcohol and other health outcomes. U.S. Hispanics are less likely to access treatment if they develop alcohol abuse or dependence, making preventive interventions critical. Familias Unidas is a family-based intervention effective in preventing drug and sexual risk behavior among Hispanic youth. The effects of this intervention specifically on youth alcohol use have been less consistent and may be affected by parental factors. The intervention is primarily delivered to parents to ultimately reduce youth risk behaviors, applying research on protective parenting and family influences, such as parental monitoring and positive communication. This study conducted secondary data analysis of an effectiveness randomized controlled trial of the Familias Unidas intervention, examining parent moderators of intervention effects on adolescent alcohol use. A total of 746 Hispanic families with 12-16-year-old adolescents were randomized to intervention or control. Logistic regression analyses confirmed no evidence of intervention effectiveness in reducing 90-day adolescent alcohol use at 30-month follow-up. However, there was evidence that parent misuse moderated intervention effects on adolescent alcohol use. Among youth whose parents reported any episode of alcohol misuse in their lifetime, the intervention was associated with lower odds of youth alcohol use at 30 months compared to youth in the control condition. Potential reasons and intervention implications are reviewed, including how parent alcohol use experiences might raise awareness of youth risks and motivate involvement or protective behaviors. Understanding intervention moderators can help shape, target, and adapt interventions to enhance their effectiveness and reach. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The relationship between age at first drink and later risk behaviours during a period of youth drinking decline

AIMS

Alcohol consumption among teenagers in many high-income countries has steadily declined since the early 2000s. There has also been a steady increase in the average age at first drink, a reliable marker of later alcohol problems. This study measured whether young people who initiated drinking early were at increased risk of alcohol problems in young adulthood in recent cohorts where early initiation was comparatively rare.

DESIGN

Analysis of six waves of a repeated cross-sectional household survey (2001-16).

SETTING

Australia.

PARTICIPANTS

A total of 9576 young adults (aged 20-25 years) who had initiated drinking before the age of 20 years.

MEASUREMENTS

Respondents were classified into three groups based on their self-reported age at first drink (< 16, 16-17, 18-19 years). Outcome variables were self-reported experiences of memory loss while drinking, risky and delinquent behaviour while drinking and monthly or more frequent drinking occasions of 11 or more 10-g standard drinks.

FINDINGS

Later initiators reported lower levels of all outcomes [e.g. odds ratios (ORs) for memory loss were 0.56, 95% confidence interval (CI) = 0.50, 0.63] for those who first drank at 16 or 17 years compared with those who first drank at age 15 or younger). Significant interactions between age at first drink and survey year showed that early initiation was more strongly associated with harms (e.g. for memory loss, OR = 0.97, 95% CI = 0.94, 0.99 for 18-19 versus 15 or younger) in young adulthood for recent cohorts where early drinking was less common.

CONCLUSIONS

The decline in youth drinking may have contributed to a concentration of risk of alcohol problems among those young people who consume alcohol in early adolescence. Early initiation of drinking may be an increasingly important marker of broader risk taking as alcohol becomes less normative for teenagers.

Russian adolescent mental health in 2002, 2015 and during the COVID-19 pandemic in 2021

BACKGROUND

Adolescent mental health is a global concern, however, time trends and the COVID-19-related restrictions vary across countries. This study examined changes in adolescent mental health and substance use in Russia between 2002, 2015 and during the pandemic in 2021.

METHODS

Cross-sectional school-based surveys of 12- to 18-year-olds were carried out in a Siberian city in 2002 (N = 713), 2015 (N = 840) and 2021 (N = 721) using the Strengths and Difficulties Questionnaire, data on tobacco, alcohol and drug use and socio-demographic information. We examined the effect of cohort, gender, family composition and parental occupation on mental health and substance use.

RESULTS

There were increases in emotional symptoms and internalising problems (B = 0.93, p < .001) and decreases in substance use over 19 years (B = -.73, p < .001). Changes in adolescent mental health and substance use were substantial from 2002 to 2015 and nonsignificant from 2015 to 2021. Increases in mental health problems were evident only among girls; a decrease in alcohol use was larger among boys. Family composition and parental occupation did not account for these changes.

CONCLUSIONS

These results suggest that the mental health of Russian adolescent girls has worsened in the 21st century; the gender gap in mental health has widened; the gender gap in alcohol use was reversed in 2021. The findings highlight the need for research into gender-specific factors and for effective interventions. The lack of changes in Russian adolescent mental health and substance use from 2015 to during the pandemic in 2021 suggests successful coping; however, more research is needed.

The great decline in adolescent risk behaviours: Unitary trend, separate trends, or cascade?

In many high-income countries, the proportion of adolescents who smoke, drink, or engage in other risk behaviours has declined markedly over the past 25 years. We illustrate this behavioural shift by collating and presenting previously published data (1990-2019) on smoking, alcohol use, cannabis use, early sexual initiation and juvenile crime in Australia, England, the Netherlands, New Zealand, and the USA, also providing European averages where comparable data are available. Then we explore empirical evidence for and against hypothesised causes of these declines. Specifically, we explore whether the declines across risk behaviours can be considered 1) a 'unitary trend' caused by common underlying drivers; 2) separate trends with behaviour-specific causes; or 3) the result of a 'cascade' effect, with declines in one risk behaviour causing declines in others. We find the unitary trend hypothesis has theoretical and empirical support, and there is international evidence that decreasing unstructured face-to-face time with friends is a common underlying driver. Additionally, evidence suggests that behaviour-specific factors have played a role in the decline of tobacco smoking (e.g. decreasing adolescent approval of smoking, increasing strength of tobacco control policies) and drinking (e.g. more restrictive parental rules and attitudes toward adolescent drinking, decreasing ease of access to alcohol). Finally, declining tobacco and alcohol use may have suppressed adolescent cannabis use (and perhaps other risk behaviours), but evidence for such a cascade is equivocal. We conclude that the causal factors behind the great decline in adolescent risk behaviours are multiple. While broad contextual changes appear to have reduced the opportunities for risk behaviours in general, behaviour-specific factors have also played an important role in smoking and drinking declines, and 'knock-on' effect from these behavioural domains to others are possible. Many hypothesised explanations remain to be tested empirically.

Energy drinks and alcohol use among adolescents: A longitudinal study

BACKGROUND

Alcohol use is a leading cause of reduced health among young people. Consumption of energy drinks might be a risk factor for alcohol use. The aim of this study was to examine if more frequent consumption of energy drinks in early adolescence was associated with higher concurrent alcohol consumption, and with stronger increase in alcohol use throughout adolescence.

METHODS

The data came from MyLife, a longitudinal study where Norwegian adolescents completed e-questionnaires in the autumn of 2017, 2018, 2019, 2020, and 2021. The participants were a nationwide sample of 2916 adolescents (mean age: 14.25 [SD = 0.85], 56% girls). At baseline, adolescents self-reported how often they had consumed energy drinks over the past month, a range of family factors, individual characteristics, and substance use. Self-reports of alcohol use (frequency, usual quantity, and frequency of consuming five or more units) were collected at all five assessments and combined into continuous variables.

RESULTS

The results of fully adjusted growth curve models indicate that more frequent consumption of energy drinks at baseline was associated with greater concurrent alcohol use (p < .001), and greater increase in alcohol use over time (p < .05). The effect of energy drinks on concurrent alcohol use was stronger for girls, but the effect on increase over time was stronger for boys.

CONCLUSION

Consumption of energy drinks in early adolescence is associated with more alcohol use throughout adolescence, but the effect size was rather modest in this sample of Norwegian adolescents.

"There's a lot of stereotypes going on": A cross-national qualitative analysis of the place of gender in declining youth drinking

INTRODUCTION

Significant declines in drinking among young people have been recorded in many high-income countries over the past 20 years. This analysis explored the role of gender - which we interpret as socially constructed and relational - to provide insight into whether and how gender might be implicated in declining youth drinking.

METHODS

Interview data from four independent qualitative studies from Australia, Denmark, Sweden and the UK (n=194; participants aged 15-19 years) were analysed by researchers in each country following agreement about analytical focus. Findings were collated by the lead author in a process of 'qualitative synthesis' which involved successive rounds of data synthesis and feedback from the broader research team.

FINDINGS

Our analysis raised two notable points in relation to the role of gender in declining youth drinking. The first concerned the consistency and vehemence across three of the countries at which drinkers and states of intoxication were pejoratively described in gendered terms (e.g., bitchy, sleazy). The second related to the opportunities non- and light-drinking offered for expressing alternate and desirable configurations of femininities and masculinities.

CONCLUSIONS

We identified an intolerance towards regressive constructions of gender that emphasise weakness for women and strength for men and a valorisation of gendered expressions of maturity through controlled drinking. Though subtle differences in gendered drinking practices between and within countries were observed, our findings offer insight into how young people's enactions of gender are embedded in, and evolve alongside, these large declines in youth drinking.

'More options…less time' in the 'hustle culture' of 'generation sensible': Individualization and drinking decline among twenty-first century young adults

There has been a dramatic decline in alcohol consumption among younger people, including an increase of conscious moderation and abstinence. Change has a generational character, with different cohorts' drinking changing over time from the heavy, embedded pattern among post-war 'boomers' to the more selective habits initiated by 'millennials'. This is a surprising development in historical terms and has been cast as indicating the emergence of a moderating 'generation sensible'. It is also coincident with more negative trends, such as young adults worsening mental health. Informed by the perspective of individualization, we consider the decline in youth drinking in the context of generational changes in the lifecourse. We focus upon how recent generations of young people experience greater choice, pressure and a prolonged adolescence, characterized by more limited autonomy. Explored with conscious young moderators through a survey (N = 517) and focus groups (N = 13), these themes resonated with our sample who appear a self-conscious generation with significant and open-ended focus upon maintaining their wellbeing and control. Further, they appear more disembedded from pressure to conform but under greater pressure to perform. The same forces of individualization encouraging moderate drinking may also weigh down upon young people who feel under pressure not only to transform their own lives but feel a burden of responsibility for a damaged, unjust world. The article's originality lies in applying individualization to both generational change and consumption, suggesting this can be usefully done through a focus upon freedom/choice and pressure/performance. It also considers what is regarded as the positive trend of drinking decline alongside, and as related to, negative trends such as greater loneliness and less autonomy among young adults.

Temporal trends in alcohol, cannabis, and simultaneous use among 12th-grade U.S. adolescents from 2000 to 2020: Differences by sex, parental education, and race and ethnicity

BACKGROUND

Simultaneous use of alcohol and cannabis to enhance each other's effect can cause potential harm. Time trends are diverging in adolescent use of alcohol, which is declining, and cannabis, which is increasing among certain subgroups. However, little is known about trends in their simultaneous and non-simultaneous use. Racial and socioeconomic disparities are emerging in cannabis use, which may portend consequences to public health.

METHODS

The 2000 to 2020 Monitoring the Future surveys included approximately 38,000 U.S. 12th-grade students with information on simultaneous use and pertinent demographic factors. A 5-level alcohol/cannabis measure included past-year simultaneous use (i.e., alcohol and cannabis use at the same time), non-simultaneous alcohol and cannabis use, alcohol-use-only, cannabis-use-only, and no use. Multinomial logistic regressions estimated associations (adjusted relative risk ratios; aRRR) with time period (2000 to 2004, 2005 to 2009, 2010 to 2014, 2015 to 2020). Models were adjusted and included interactions with sex, race/ethnicity, and parental education.

RESULTS

Between 2000 and 2020, simultaneous alcohol/cannabis use among 12th graders decreased from 24.4% to 18.7%. From 2015 to 2020 compared to 2000 to 2004, the odds of simultaneous use (adjusted relative risk ratio (aRRR) vs. no use = 0.57, 95% CI [0.50, 0.66]) and alcohol-use-only (aRRR = 0.55, 95% CI [0.49, 0.61]) decreased, while cannabis-use-only odds increased (aRRR = 2.59, 95% CI [1.87, 3.59]). Notably, the prevalence of cannabis-use-only more than doubled from 2011 to 2019. The odds of simultaneous use, alcohol-use-only, and non-simultaneous use of alcohol and cannabis declined more rapidly among males than females, whereas the odds for cannabis-use-only increased faster for females than males. Increases in cannabis-use-only were faster for non-white adolescents.

CONCLUSION

Simultaneous use of alcohol and cannabis is declining among U.S. adolescents, but the decline is slower among females than males. Declines in simultaneous use are largely concomitant with historical declines in alcohol use, indicating that a continued focus on reducing alcohol use among adolescents and young adults has extended benefits to other adolescent substance use. However, cannabis use without any reported past-year alcohol use more than doubled in the last decade, a concerning trend.

The Declining Trend in Adolescent Drinking: Do Volume and Drinking Pattern Go Hand in Hand?

Traditionally, adolescent drinking cultures differed between Nordic and Mediterranean countries; the former being characterised by low volume and relatively frequent heavy episodic drinking (HED). Across these drinking cultures, we examined the associations between alcohol volume and HED with respect to (i) secular trends at the country level and (ii) individual-level associations over time. The data stem from the European School Survey Project on Alcohol and Other Drugs (ESPAD) conducted among 15–16-year-olds in Finland, Iceland, Norway, Sweden, France and Italy, employing six cross-sectional surveys from 1999 to 2019 (n = 126,126). Both consumption volume and HED frequency decreased in all Nordic countries and displayed a curvilinear trend in France and Italy. In all countries, consumption volume and HED correlated highly over time at the country level. At the individual level, the correlation was positive but with a varying magnitude over time and between countries. In 1999/2003, the alcohol volume–HED correlation was significantly higher in the Nordic compared to the Mediterranean countries but became significantly weaker in Finland, Norway and Sweden and remained stable in France, Iceland and Italy during the period. In conclusion, while trends in consumption volume and drinking patterns went hand in hand at the aggregate level, the association at the individual level weakened over time in several Nordic countries, along with the substantial decline in adolescent drinking since 2000.

Declining Trend in Adolescent Alcohol Use: Does It Have Any Significance for Drinking Behaviour in Young Adulthood?

Since 2000, adolescent alcohol use has declined substantially in many high-income countries, particularly in Northern Europe. This study examined whether birth cohorts in Norway who experienced different levels of alcohol consumption in mid-adolescence differed in drinking behaviour when they reached young adulthood. We analysed data from annual population surveys in Norway (2012–2021). The analytic sample comprised data from respondents aged 20–29 years (N = 5266), and we applied four birth cohorts (i.e., 1983–1987, 1988–1992, 1993–1996 and 1997–2001). We applied age categories with two- and five-year intervals and tested whether drinking frequency, heavy episodic drinking (HED) and usual number of drinks per drinking occasion during the past 12 months differed by birth cohort in age-specific strata. Possible cohort differences within age groups were tested using Pearson’s Chi square. There were no statistically significant differences between cohorts with respect to drinking frequency or HED frequency. However, the youngest cohort had fewer drinks per occasion when in their early 20s compared to older cohorts. This study showed that birth cohorts who differed substantially in levels of alcohol consumption in mid-adolescence, only to a little extent differed in drinking behaviour in young adulthood.

To drink or not to drink: A study of the association between rates of non-drinkers and per drinker mean alcohol consumption in the Swedish general population

INTRODUCTION

Understanding how the mean consumption per drinker and rates of non-drinking interplay to form overall per capita alcohol consumption is imperative for our understanding of population drinking. The aim of the present study is to examine the association between rates of non-drinkers and per drinker mean alcohol consumption in the Swedish adult population and for different percentiles of drinkers.

METHODS

Data came from a monthly telephone survey of drinking habits in the Swedish adult population between 2002 and 2013. Alcohol consumption and non-drinking during the last 30 days were measured by beverage-specific quantity-frequency questions. Regression models estimated the association between the rate of non-drinkers and per drinker volume on annual data. Auto-regressive integrated moving average time-series models estimated the association on monthly data.

RESULTS

A significant (P < 0.01) negative association (-0.849) was found between the rate of non-drinkers and per drinker mean volume on annual data. A unit increase in non-drinking was associated with a decline of 0.85 cl of pure alcohol among drinkers. This finding was mirrored across all percentiles of consumption. The semi-log models found that a 1% unit increase in the rate of non-drinkers was followed by a 2% reduction in per drinker mean consumption. Auto-regressive integrated moving average time-series models verified these results.

DISCUSSION AND CONCLUSIONS

There is a significant association between the proportion of non-drinkers and the amount of drinking among drinkers. The theory of collectivity of drinking cultures should also include the non-drinking part of the population.

Declining drinking among adolescents: Are we seeing a denormalisation of drinking and a normalisation of non-drinking?

BACKGROUND

In the early 2000s, alcohol use among young people began to decline in many western countries, especially among adolescents (ages between 12-17 years old). These declines have continued steadily over the past two decades, against the backdrop of much smaller declines among the general population.

ARGUMENT

Hypotheses examining individual factors fail adequately to provide the necessary 'big picture' thinking needed to understand declines in adolescent drinking. We use the normalisation thesis to argue that there is strong international evidence for both processes of denormalisation of drinking and normalisation of non-drinking occurring for adolescents in many western countries.

CONCLUSIONS

Research on declining adolescent drinking provides evidence of both denormalisation of alcohol consumption and normalisation of non-drinking. This has implications for enabling policy environments more amenable to regulation and increasing the acceptability of non-drinking in social contexts. Normalisation theory (and its various interpretations) provides a useful multi-dimensional tool for understanding declines in adolescent drinking.

Declines in alcohol consumption in Australia: some challenges to the theory of collectivity

BACKGROUND AND AIMS

There is significant debate about whether or not changes in per-capita alcohol consumption occur collectively across the entire distribution of drinking. This study used data from a decade of declining drinking in Australia to test the collectivity of drinking trends.

DESIGN

Repeated cross-sectional surveys (2010, 2013, 2016, 2019), analysed with quantile regression techniques assessing trends in drinking for 20 quantile groups.

SETTING

Australia.

PARTICIPANTS

A general population sample (total n = 85 891; males = 39 182, females = 46 709) aged 14 years and over.

MEASUREMENTS

Past-year volume of alcohol consumed was measured using standard graduated frequency survey questions. Models were stratified by sex and age group.

FINDINGS

Throughout the whole population, alcohol consumption had declined in all percentile groups, with the largest proportional declines evident for light and moderate drinkers [e.g. drinkers in the 25th percentile declined by 32.7%; 95% confidence interval (CI) = -41.6, -22.3% per wave]. Broadly collective declines were also found for younger men and women with significant declines in every percentile group, but older groups showed some evidence of polarization. For example, women aged 45-64 years significantly increased their consumption (2.9% per wave, 95% CI = 0.3-5.5%), while consumption for those in the 25th percentile fell significantly (-16.7%, 95% CI = -27.6, -4.2%).

CONCLUSIONS

The declines in Australian drinking since 2010 have included important deviations from the collectivity predicted by Skog's influential theory of collectivity of drinking, with markedly different patterns evident among different demographic groups.

Tracking the decline in Australian adolescent drinking into adulthood

BACKGROUND AND AIMS

Adolescent drinking in Australia (and many other countries) has declined substantially since the early 2000s. This study aimed to test whether these declines have been maintained into adulthood and whether they are consistent across sub-groups defined by sex and socio-economic status.

DESIGN

Quasi-cohorts were constructed from seven repeated waves of cross-sectional household survey data (2001-2019).

SETTING

Australia.

PARTICIPANTS

A total of 20 733 respondents age between 14 and 24 (male: 9492; female: 11 241).

MEASUREMENTS

Participants were grouped into five cohorts based on their birth year (from 1979-1983 to 1999-2003). Three measures of drinking were assessed: any past-year consumption (yes/no), past-year regular risky drinking (12 or more drinking episodes of >40 g of pure alcohol, yes/no) and total volume of alcohol consumed in the past year (in Australian standard drinks, 10 g of alcohol). Socio-economic status was measured based on neighbourhood of residence.

FINDINGS

Drinking declines were consistent across socio-economic groups on all measures and trends were broadly similar for women and men. More recent birth cohorts had significantly lower levels of drinking across all three measures (odds ratios between 0.31 and 0.70 for drinking and risky drinking, coefficients between -0.28 and -0.80 for drinking volume). There were significant interactions between birth cohort and age for past-year drinking and past-year regular risky drinking, with cohort differences diminishing as age increased.

CONCLUSIONS

Lighter drinking adolescent cohorts appear to partly 'catch up' to previous cohorts by early adulthood, but maintain lower levels of drinking and risky drinking up to the age of 24. These ongoing reductions in drinking are spread evenly across socio-economic groups.

Parent/caregiver attitudes, motivations and behaviours in relation to alcohol use among offspring aged 13-18 years: a qualitative study

BACKGROUND

Parental alcohol consumption and alcohol-related behaviour play a critical role in shaping adolescent alcohol use, but comparatively little is known about the perspectives of parents regarding adolescent alcohol use from qualitative studies in England. This study aimed to explore parental views and attitudes towards alcohol use during adolescence, among their offspring and among young people in general.

METHODS

Twenty-three parents (21 mothers, 2 fathers) of children aged 13-18 years were recruited via schools, workplaces and community settings, predominantly in the West of England (n = 19) between 2017 and 2018. Data were collected via in-depth one-to-one interviews and analysed thematically, using an inductive, constructionist approach.

RESULTS

Five major themes were identified in the data: (1) the parental alcohol environment, (2) balance and acceptance, (3) influences of the parental approach, (4) boundaries and parental monitoring, and (5) wider influences shaping young people's behaviour. Overall, parents were aware of the risks and consequences of alcohol use and the wide range of influences shaping drinking behaviour, and expressed broad disapproval of alcohol use among young people. However, adolescent alcohol use was viewed as inevitable, and set within a context of a tolerant drinking culture. Many parents therefore chose a balanced and reluctantly accepting approach. This approach was determined by weighing disapproval of drinking against consistency with wider culture and parental behaviour, support for autonomy of the child, and avoidance of social sanctions. Parents' responses were also determined by a desire to protect the parent-child relationship, maintain an open, communicative and trusting relationship, and ultimately limit risk and minimise harm. Various boundaries and strategies were employed to this end, including care around role modelling, gradual introductions to alcohol, boundaried provision, clear risk reduction messaging and parental monitoring.

CONCLUSIONS

Parents employ a range of mechanisms to reduce alcohol-related risk and to balance harms of alcohol use among their offspring against adolescent behavioural norms. A downward shift in community consumption and changing socio-cultural norms could alter the accepting context in which parents are required to navigate adolescent alcohol use.

Youth drinking in decline: What are the implications for public health, public policy and public debate?

Youth drinking has declined across most high-income countries in the last 20 years. Although researchers and commentators have explored the nature and drivers of decline, they have paid less attention to its implications. This matters because of the potential impact on contemporary and future public health, as well as on alcohol policy-making. This commentary therefore considers how youth drinking trends may develop in future, what this would mean for public health, and what it might mean for alcohol policy and debate. We argue that the decline in youth drinking is well-established and unlikely to reverse, despite smaller declines and stabilising trends in recent years. Young people also appear to be carrying their lighter drinking into adulthood in at least some countries. This suggests we should expect large short- and long-term public health benefits. The latter may however be obscured in population-level data by increased harm arising from earlier, heavier drinking generations moving through the highest risk points in the life course. The likely impact of the decline in youth drinking on public and policy debate is less clear. We explore the possibilities using two model scenarios, the reinforcement and withdrawal models. In the reinforcement model, a 'virtuous' circle of falling alcohol consumption, increasing public support for alcohol control policies and apparent policy successes facilitates progressive strengthening of policy, akin to that seen in the tobacco experience. In the withdrawal model, policy-makers turn their attention to other problems, public health advocates struggle to justify proposed interventions and existing policies erode over time as industry actors reassert and strengthen their partnerships with government around alcohol policy. We argue that disconnects between the tobacco experience and the reinforcement model make the withdrawal model a more plausible scenario. We conclude by suggesting some tentative ways forward for public health actors working in this space.

Are changes in attitudes towards school associated with declining youth drinking? A multi-level analysis of 37 countries

BACKGROUND

Changes in adolescents' attitudes towards school are a potential explanation for recent declines in young people's alcohol consumption. However, this has not been tested using multi-national survey data, which would permit stronger causal inferences by ruling out other country-specific explanations. This study, therefore, uses an international survey of schoolchildren to examine the associations between changing attitudes towards school and adolescent alcohol consumption.

METHODS

We used data from 247 325 15-year-olds across 37 countries participating in four waves of the Health Behaviour in School-aged Children study (2001/02-2013/14). Attitudes towards school were assessed using two measures-self-reported pressure from schoolwork and whether respondents like school. Outcome measures were weekly alcohol consumption and having been drunk twice in one's lifetime. We used whole population and gender-specific hierarchical linear probability models to assess the relationship between attitudes and alcohol outcomes within countries over time.

RESULTS

Country-level changes over time in liking school were not associated with changes in alcohol consumption. However, a 10% increase in feeling pressured by schoolwork was associated with a 1.8% decline in drunkenness [95% confidence interval (CI): -3.2% to -0.3%] and weakly associated with a 1.7% decline in weekly drinking (95% CI: -3.6% to 0.2%). Among girls only, increases in feeling pressured by schoolwork were associated with a 2.1% decline in weekly drinking (95% CI: -3.7% to -0.6%) and a 2.4% decline in drunkenness (95% CI: -3.8% to -1.1%).

CONCLUSION

Changes in attitudes towards school may have played a minor role in the decline in alcohol consumption among adolescent girls only.

Becoming Safe, Legal, Mature, Moderate, and Self-Reflexive: Trajectories of Drinking and Abstinence among Young People

In recent years, a vast body of research has investigated trends of declining alcohol consumption among youths. However, the extent to which restrictive-youth approaches towards drinking are maintained into adulthood is unclear. The aim of this study is to explore how young people's relation to alcohol changes over time. Our data are based on longitudinal qualitative in-depth interviews with 28 participants aged 15 to 23 conducted over the course of three years (2017-2019). The study draws on assemblage thinking by analysing to what kinds of heterogeneous elements young people's drinking and abstinence are related and what kinds of transformations they undergo when they get older. Five trajectories were identified as influential. Alcohol was transformed from unsafe to safe assemblages, from illegal to legal drinking assemblages, from performance-orientated to enjoyment-orientated assemblages, and from immature to mature assemblages. These trajectories moved alcohol consumption towards moderate drinking. Moreover, abstinence was transformed from authoritarian assemblages into self-reflexive assemblages. Self-control, responsibility, and performance orientation were important mediators in all five trajectories. As the sober generation grows older, they will likely start to drink at more moderate levels than previous generations.

An examination of the role of changes in country-level leisure time internet use and computer gaming on adolescent drinking in 33 European countries

INTRODUCTION

Adolescent alcohol consumption has been declining in many high-income countries since the turn of this century. Research investigating the plausible explanations for these declines has been mostly based on individual-level studies, which are largely inconclusive. Changes in leisure time internet use and computer gaming (referred to in this article as 'computer activities') have been hypothesised to play a role in declining adolescent alcohol consumption at a country-level. The aim of this study was to examine the association between country-level changes over time in computer activities and adolescent drinking in 33 European countries.

METHODS

This is a multi-level repeated cross-national study examining the role of changes over time in country-level and individual-level computer activities on regular drinking. We utilised four waves of the European School Survey Project on Alcohol and Drugs (ESPAD) from 2003, 2007, 2011 and 2015. At an individual-level the primary exposure of interest was daily engagement in computer activities and aggregated means were used to measure country-level daily computer activities in each included country. Data were analysed using three-level hierarchical linear probability methods.

RESULTS

In the fully adjusted model, for between individual effects, we found significant positive association between daily computer activities and regular drinking (β = 0.043, p-value <0.001 and 95% CI = 0.033-0.054). However, at a country-level, we did not find any association between within-country changes in daily computer activities and regular drinking (β = 0.031, p-value = 0.652 and 95% CI = -0.103-0.164.

CONCLUSION

Findings from this study suggest that broad cultural shifts towards increased computer-based activities among adolescents has played a little or no role in declining adolescent drinking. Future research should be directed towards examining other high-level cultural changes which may have influenced cross-national reductions in adolescent drinking.

17 Is the New 15: Changing Alcohol Consumption among Swedish Youth

To examine and compare trends in drinking prevalence in nationally representative samples of Swedish 9th and 11th grade students between 2000 and 2018. A further aim is to compare drinking behaviours in the two age groups during years with similar drinking prevalence. Data were drawn from annual surveys of a nationally representative sample of students in year 9 (15-16 years old) and year 11 (17-18 years old). The data covered 19 years for year 9 and 16 years for year 11. Two reference years where the prevalence of drinking was similar were extracted for further comparison, 2018 for year 11 (n = 4878) and 2005 for year 9 (n = 5423). The reference years were compared with regard to the volume of drinking, heavy episodic drinking, having had an accident and quarrelling while drunk. The prevalence of drinking declined in both age groups during the study period. The rate of decline was somewhat higher among year 9 students. In 2018, the prevalence of drinking was the same for year 11 students as it was for year 9 students in 2005. The volume of drinking was lower among year 11 students in 2018 than year 9 students in 2005. No differences were observed for heavy episodic drinking. The decline in drinking has caused a displacement of consumption so that today's 17-18-year-olds have a similar drinking behaviour to what 15-16-year-olds had in 2005.

Are changes in parenting related to the decline in youth drinking? Evidence from a comparison of Sweden and Denmark

Introduction: The aim of this study was to replicate earlier studies suggesting that changes in parenting have contributed to the recent decline in youth drinking by comparing parenting in a country experiencing a sharp decline in youth drinking (Sweden) with a country with only a small decline (Denmark). Data and analysis: Data stem from self-reported information from 15–16-year-old children in the Swedish and Danish subsamples of ESPAD. Youth drinking was measured by prevalence and frequency of drinking over the past year. Parenting was measured in terms of the extent the child reported that: (1) parents’ attitudes towards offspring drinking are restrictive, (2) parents set up general rules for what their children are allowed to do, and (3) parents have high level of knowledge about where and with whom their children spend time. The association between these indicators of parenting and youth drinking was first estimated with logistic regressions. Second, changes in parenting between 1999 and 2015 were compared between Denmark and Sweden across the study period. Results: Restrictive parental attitudes were associated with a lower likelihood of past-year drinking and frequent drinking in both Sweden and Denmark. This attitude was more common in Sweden, where it also became more prevalent between 2003 and 2015 in contrast to in Denmark. The association between strict parental rule-setting and youth drinking was weak in both countries. A high parental knowledge of the child's whereabouts was linked to a lower likelihood of past-year drinking in Sweden and a lower frequency of drinking in both countries. Parental knowledge of offspring's whereabouts did not develop differently in Sweden and Denmark, with a high and stable proportion in both countries. Conclusion: More restrictive parental attitudes towards youth drinking may have contributed to the decline in youth drinking, whereas the importance of general parental rule-setting and parental knowledge of offspring's whereabouts was not supported.
