Assessing alcohol industry penetration and government safeguards: the International Alcohol Control Study.

Background: The alcohol industry uses many of the tobacco industry's strategies to influence policy-making, yet unlike the Framework Convention on Tobacco Control, there is no intergovernmental guidance on protecting policies from alcohol industry influence. Systematic assessment of alcohol industry penetration and government safeguards is also lacking. Here, we aimed to identify the nature and extent of industry penetration in a cross-section of jurisdictions.

The alcohol harm paradox: is it valid for self-reported alcohol harms and does hazardous drinking pattern matter?

Background: The alcohol harm paradox (APH) posits that alcohol harms are more prevalent in low socioeconomic position (SEP) groups compared to high SEP groups, when adjusted for alcohol consumption volume.

Aim: We explored whether APH is valid for self-reported alcohol harms and whether SEP differences in hazardous drinking patterns may explain SEP differences in alcohol harms, accounting for consumption volume.

Data And Methods: We applied cross-sectional data from national population surveys in Norway, restricted to a subsample of past month drinkers aged 25-79 years (n = 8 171).

Effect of a small increase in off-premises trading hours on alcohol sales in Norway: A stepped-wedge cluster-randomized controlled trial.

Background And Aims: Evidence of the effect of limiting off-premises alcohol trading hours is still scarce. This study tested the effect of a small extension in trading hours on alcohol sales in alcohol monopoly outlets in Norway.

Design: The extension of trading hours was implemented within a stepped-wedge cluster-randomized trial design.

Gambling consumption and harm: a systematic review of the evidence.

The total consumption model (TCM) postulates a close link between total consumption and levels of harm within the population, which has important implications for prevention. This review aimed to explore evidence relating to the application of the TCM and theoretical elements associated with it (i.e.

A nationwide study on time spent on social media and self-harm among adolescents.

Self-harm among adolescents has increased in many countries, but few studies have examined possible explanations. One explanation could be the changes in the way adolescents socialize and use of social media. We explored the relationship between past year self-harm and time spent on social media, employing data from a nationwide cross-sectional survey among students in grades 8 through 11 in Norway (N = 37,268).

Mortality and alcohol-related morbidity in patients with delirium tremens, alcohol withdrawal state or alcohol dependence in Norway: A register-based prospective cohort study.

Background And Aims: Little is known about long-term consequences of delirium tremens (DT). This study aimed to compare all-cause and cause-specific mortality and alcohol-related morbidity between patients with: (i) DT, (ii) alcohol withdrawal state (AWS) and (iii) alcohol dependence (AD).

Design: A national longitudinal health registry study with linked data from the Norwegian Patient Registry and the Norwegian Cause of Death Registry.

Temporal order of diagnosis between gambling disorder and substance use disorders: Longitudinal results from the Norwegian Patient Registry.

Introduction: Previous research has established co-occurrence between substance use disorders (SUDs) and gambling disorder (GD). Less well understood is the temporal sequencing of onset between these disorders, and in particular whether SUD is a risk factor for GD. The present study examined the temporal order between registered diagnoses of SUD and GD, stratified by sex.

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.

Alcohol: No Ordinary Commodity-a summary of the third edition.

Background And Aims: This article summarizes the findings and conclusions of the third edition of Alcohol: No Ordinary Commodity. The latest revision of this book is part of a series of monographs designed to provide a critical review of the scientific evidence related to alcohol control policy from a public health perspective.

Design: A narrative summary of the contents of the book according to five major issues.

Self-exclusion from gambling: A toothless tiger?

While there is evidence for self-exclusion (SE) as an individual-level harm reduction intervention, its effects on reducing harm from gambling at the population level remain unclear. Based on a review of national legal frameworks and SE programs, including their utilization and enforcement in selected high-income societies, the present analysis aims to explore the reach and strengths of SE in the protection of gamblers in these jurisdictions. It places particular emphasis on SE programs' potential to prevent and minimize gambling harm at the population level.

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).

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).

Patients admitted to treatment for substance use disorder in Norway: a population-based case-control study of socio-demographic correlates and comparative analyses across substance use disorders.

Background: Improved knowledge regarding socio-demographic correlates of people with substance use disorders (SUDs) is essential to better plan and provide adequate services for SUD patients and their families, and to improve our understanding of the complex mechanisms underlying progression into and development of various SUDs. This study aimed to: i) describe demographic, economic, and social correlates of people with SUDs in comparison with those of the general population and ii) compare these correlates across SUDs from licit versus illicit substances, as well as across specific SUDs.

Methods: A national population-based case-control study included all SUD patients enrolled in specialized drug treatment in Norway in 2009-2010 (N = 31 245) and a population control sample, frequency-matched on age and gender (N = 31 275).

The importance of alcohol in elderly's hospital admissions for fall injuries: a population case-control study.

Background: Fall injuries account for a substantial part of the health burden among elderly persons, and they often affect life quality severely and impose large societal costs. Alcohol intoxication is a well-known risk factor for accidental injuries, but less is known about this association among elderly people. In this study, our aim was to assess whether risk of fall injuries among the elderly is elevated with an intoxication-oriented drinking pattern.

Are short AUDIT screeners effective in identifying unhealthy drinking of varying severity? A prison population study.

Background: Whether brief versions of the Alcohol Use Disorder Identification Test (AUDIT) can be used as graded severity measures is largely unknown. We examined the performance of eight such brief screeners in a prison population, and compared their effectiveness in detecting hazardous drinking, harmful drinking, and possible alcohol dependence as classified by the full ten-item AUDIT.

Methods: The study sample included pre-prison drinkers who participated in the Norwegian Offender Mental Health and Addiction (NorMA) study (n = 758).

Heavy drinkers and the contexts of drinking among adults in Norway.

Background: There is little knowledge about characteristics of the heaviest drinkers. This study aimed at exploring 1) socio-demographic characteristics and 2) drinking patterns and drinking contexts of heavy drinkers and other drinkers in Norway, applying various criteria for heavy drinking.

Methods: Data from cross-sectional population surveys among adults in Norway (aged 16 +) in 2015 through 2018 (current drinkers, n = 6 940) were analysed.

Effect of extended trading hours on alcohol sales in Norway: study protocol for a stepped wedge cluster-randomized trial.

Background And Aims: Norwegian alcohol policy measures include national restrictions on sales hours and a state monopoly on retail sales. A 1-hour extension of sales hours on Saturdays in the monopoly outlets took effect from September 2020. We aim to evaluate whether increase in sales hours results in (1) an increase in alcohol sales in the monopoly outlets and (2) an increase in total alcohol sales, including substitution effects from beer sales in grocery stores.

Measuring changes in alcohol use in Finland and Norway during the COVID-19 pandemic: Comparison between data sources.

Objectives: To examine (1) how a rapid data collection using a convenience sample fares in estimating change in alcohol consumption when compared to more conventional data sources, and (2) how alcohol consumption changed in Finland and Norway during the first months of the COVID-19 pandemic.

Methods: Three different types of data sources were used for the 2nd quarter of 2020 and 2019: sales statistics combined with data on unrecorded consumption; the rapid European Alcohol Use and COVID-19 (ESAC) survey (Finland: n = 3800, Norway: n = 17,092); and conventional population surveys (Finland: n = 2345, Norway: n1 = 1328, n2 = 2189, n3 = 25,708). Survey measures of change were retrospective self-reports.

Stronger alcohol-violence association when adolescents drink less? Evidence from three Nordic countries.

Background: Since 2000, adolescents' alcohol use and heavy episodic drinking (HED) have declined in the Nordic countries. However, little is known about corresponding trends in alcohol-related harm and possible changes in the alcohol-harm association. The aims are to examine (i) whether the decline in HED was accompanied by a decline in alcohol-related violence (AV) and (ii) whether the strength of the HED-AV association changed concomitant with the decline.

The alcohol advertising ban in Norway: A response to Nelson's comments.

In a recent analysis of the effect of the complete advertising ban on alcohol in Norway, I found that the ban led to a decrease in recorded alcohol sales. Jon Nelson offers comments on this study in two regards; my critical comments on his previous study of alcohol advertising bans and the time series analysis in my study. In this response to Nelson, I offer further explanation for my comments on Nelson's previous study and for the appropriateness of the analysis.

Changes in Alcohol Consumption during the COVID-19 Pandemic-Small Change in Total Consumption, but Increase in Proportion of Heavy Drinkers.

Little is known about possible changes in alcohol consumption distribution during the COVID-19 pandemic. We estimated how individual changes in alcohol consumption during the pandemic translated into changes in: (i) mean consumption; (ii) dispersion of consumption distribution; and (iii) prevalence of heavy drinkers. We employed data from two independent web-surveys of Norwegian adults collected between April and July 2020 and limited to those reporting past year alcohol consumption ( = 15,267, = 1195).
