The Efficacy of Nutritional Interventions in Reducing Childhood/Youth Aggressive and Antisocial Behavior: A Mixed‐Methods Systematic Review and Meta‐Analysis

By Barna Konkolÿ Thege|, Chaz Robitaille, Lujayn Mahmoud, Eden A. Kinzel, Rameen Qamar, Jamie Hartmann‐Boyce, Oliia Choy

Aggressive/antisocial behaviors in children and youth may result in impairments in family, social, or academic functioning and lead to long‐term negative consequences for both the individual and society as a whole. The potential of healthy dietand nutritional supplements to reduce aggression and antisocial behavior is an active area of study in nutritional mental health sciences. The goal of this systematic review is to (1) investigate the effectiveness/efficacy of nutritional interventions(dietary manipulation, fortification or supplementation) in reducing excessive aggression, antisocial behaviors, and criminal offending in children/youth (systematic review and meta‐analysis); and (2) provide an overview of implementation barriers and facilitators regarding nutritional interventions in children/youth (qualitative/narrative synthesis). After consulting theCampbell Collaboration's methodological guidelines, a comprehensive search for published and unpublished papers on controlled intervention studies was performed (up to February 26, 2024) using both electronic databases (MEDLINE,Embase, Cochrane Library, APA PsycInfo, Scopus, and the Allied and Complementary Medicine Database) and otherresources (e.g., Google Scholar, reference list of included studies and other reviews, websites of public health agencies). Thisstudy focuses on children and youth (up to the age of 24) presenting with an above‐average level of aggression/antisocial behavior. In terms of the intervention, we considered both dietary manipulation and nutritional supplementation with aduration long enough (minimum of 1 week) that a significant change in the individual's nutritional status could be expected.We included studies with a controlled design if, for outcomes, they reported on (1) behavioral‐level violence/aggression toward others in real‐life (non‐simulated) settings, (2) antisocial behaviors, or (3) criminal offending. Initial screening,checking for eligibility criteria, data extraction from, and risk of bias assessment for each eligible study were conducted independently by two reviewers. To perform the meta‐analysis, data from each original report were standardized(transformed into Hedges' g) so that results across studies could be meaningfully combined and interpreted. Data con-versions, computation of pooled effect sizes, and estimation of publication bias were conducted using the Comprehensive Meta‐analysis software (Version 4). Altogether, 51 reports (describing 50 individual studies) met our inclusion criteria, and72 effect sizes were extracted from these reports. Nutritional interventions with a broad target (e.g., broad‐spectrummicronutrient supplementation or general improvement in diet quality) had the most consistent and largest interventionThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.© 2025 The Author(s).

Policy Thoughts on Bounded Rationality of Identity Thieves

By Graeme R. Newman

This essay critiques a study by Copes and Vieraitis regarding the "bounded rationality" of identity thieves, arguing that a focus on offender psychology and rationalizations is insufficient for developing effective crime reduction policies[cite: ]Newman contends that current criminal justice approaches rely too heavily on punishment and victim vindication, which, while politically satisfying, fail to reduce the prevalence of identity theft.

The author advances the following arguments regarding the development of effective policy:

* Policies based on the "deep psychology" of offenders or their denial of victims are largely fruitless because these rationalizations are often unconscious defense mechanisms. Instead of asking “why” offenders commit crimes, policy should focus on “how” they are accomplished.

* Newman distinguishes between crime mitigation (reducing damage to victims) and crime prevention (reducing the number of crimes)[cite:. While legislation and credit reporting agencies have improved mitigation efforts for victims, these measures do not address the root causes of the crime.

* Effective prevention must target the technological and business arrangements that create opportunities for theft. This involves shifting focus from the offender to the "significant players" (businesses) who can implement standard security procedures, such as the use of PINs for credit cards, to harden targets.

* The essay concludes that businesses often view fraud merely as a cost of doing business rather than a crime to be prevented[cite:. Therefore, the government must establish policies that compel businesses to accept responsibility for crime reduction and eliminate the opportunities they create through their products and services[cite.

Classical Deception: Counterfeits, Forgeries and Reproductions of Ancient Coins

Wayne G. Sayles:


Classical Deception is a detailed and accessible exploration of the long history of counterfeit ancient coins and the methods by which they are produced, detected, and sometimes unwittingly circulated within the numismatic world. Designed for collectors, students of antiquity, and museum professionals alike, the book traces forgery practices from antiquity to the modern era, showing that imitations have accompanied genuine coinage for as long as coins have existed. Sayles examines a spectrum of deceptions — from ancient contemporary counterfeits meant to pass in daily commerce, to the sophisticated modern forgeries that challenge even seasoned experts.

A substantial portion of the book profiles well-known forgers, documenting their techniques, motives, and the specific pieces they produced. Sayles pays particular attention to the prolific work of modern reproduction artists, including Peter Rosa, whose replicas are widely encountered and often misunderstood by beginning collectors. More than 200 photographs allow readers to visually compare authentic coins with their deceptive counterparts, highlighting telltale markers in style, fabric, metallurgy, and die workmanship.

Sayles also introduces the scientific and observational tools available to detect fakes — from simple weight measurement and magnified study of surfaces to metallurgical testing, microscopy, and imaging technologies. Throughout, he emphasizes practical guidance: what warning signs to look for, how to assess provenance, and how to avoid costly errors in the marketplace.

Ultimately, Classical Deception serves both as a cautionary manual and as a historical study of ingenuity, fraud, and craftsmanship. It equips the reader to navigate the hazards of collecting while deepening appreciation for the authentic artistry of ancient coinage.

Perspectives on Identity Theft

By Megan M. McNally and Graeme R. Newman

From the cover: There has been a glaring lack of scholarly attention to the crime of identity theft, according to the editors. The chapters in this volume attempt to fill some of this gap by exploring theory and research on identity theft, as well as situational measures to prevent its occurrence.

The editors' introduction outlines several key issues related to the definition, extent and commission of identity theft. The chapter by Graeme Newman applies the opportunity perspective to the study of identity theft. Megan

McNally uses the "script" approach to examine the meaning and mechanics of identity theft in all of its forms. Henry Pontell, Gregory Brown and Anastasia Tosouni present new findings on how identity theft affects victims, based on data collected by the Identity Theft Resource Center. Heith Copes and Lynne Vieraitis describe how a sample of identity theft offenders viewed their crimes. Michael Levi recounts the evolution of identity fraud and its control in the U.K. Russell Smith presents a framework for evaluating preventive measures, particularly document-based systems, biometric technologies and identity cards. Sara Berg considers how information technology can be used within a situational crime prevention framework to fight identity theft. Robert Willison examines the use of situational crime prevention to protect sensitive personal information in the context of information systems security.

Why Place Matters: Neighbourhood Effects on Crime and Anti-Social Behaviour: Insights Report

By Sophie Davis Manon Roberts Freya Smith

Neighbourhoods — understood here as the small, local areas people identify with in their daily lives which do not necessarily align with official administrative boundaries — play a central role in shaping people’s experiences of crime and safety. This is particularly true in relation to anti-social behaviour (ASB) and visible disorder. These issues, while often seen as less serious than violent crime, directly affect people’s day-to-day lives by shaping perceptions of safety, trust in institutions, and community cohesion. This paper makes the case for why neighbourhoods must be at the heart of crime policy — both as spaces where crime is experienced and as sites of potential solutions. The evidence is clear: the social and physical conditions of neighbourhoods are not incidental to crime — they help to generate it and shape how people respond to it. Poor lighting, unmanaged public spaces, and the erosion of social ties can all create the conditions in which ASB and crime thrive. Crucially, these neighbourhood characteristics can also be changed. Interventions that enhance the built environment, foster informal guardianship, and build local trust can have a preventative effect, reducing demand and improving outcomes cost-effectively. Over the past three decades, policy has increasingly acknowledged this link with initiatives such as Crime and Disorder Reduction Partnerships, neighbourhood policing and the Safer Streets Fund. These initiatives reflect a wider recognition that local, place-based approaches, built on strong partnerships and trust, are essential. However, the effectiveness of such approaches has often been undermined by fiscal constraints, insufficient targeting of the most affected neighbourhoods and a lack of investment in the social connections that sustain resilient communities. The government wants to ‘take back our streets’ as one of its key missions. In its June 2025 Spending Review, the government announced a new national commitment to improving 350 deprived communities, and a £240 million investment in a Growth Mission Fund — signalling a renewed commitment to place-based approaches. It was also announced that police spending power will grow by 1.7% annually, to support the government’s mission to make streets safer, complementing a pledge made in April 2025 to ‘restore local policing’ and a commitment to placing 13,000 neighbourhood police officers and police community support officers (PCSOs) into dedicated community roles. To achieve its ambitions, the government needs to ‘think neighbourhoods’: focus on areas where harm is greatest, invest in the social foundations of safety and deliver quick, visible improvements. Neighbourhood-focused approaches are not only effective, they are efficient. With limited public finances, place-based approaches offer a strategic route to delivering high-impact, low-cost crime reduction, particularly in relation to ASB and disorder. But achieving the government’s mission to ‘take back our streets’ requires more than additional police officers. It requires investing in both places and people — building social capital and strengthening cohesion — to prioritise key issues and needs at a place-based level.Summary of key findings Crime is heavily concentrated and persistent in areas of multiple disadvantage. A small proportion of geographic areas account for a disproportionate share of crime and ASB. These areas often face persistent poverty, underinvestment, and institutional neglect, which foster conditions for crime to take root and persist. Residents in these areas report significantly greater concerns about ASB, illegal drugs and safety, and feel less connected and optimistic about their communities. Disadvantage and instability reinforce each other, weakening community control. Factors such as residential turnover can interact with disadvantage to undermine social cohesion, weakening informal social control and making communities more vulnerable to ASB and crime. The built environment shapes both risk and resilience. Urban design influences crime not only by affecting opportunities for offending but also by shaping perceptions of safety, trust and community pride, and enabling more positive use of public space, including through increased natural surveillance and by supporting informal guardianship. Social cohesion and trust can act as protective factors, particularly in areas of disadvantage. Strong social bonds, shared norms, and a collective willingness to intervene (collective efficacy) can help neighbourhoods resist crime and ASB, even in deprived areas. Crime and ASB matter to communities — they act as wider signals of neighbourhood decline. Visible signs of disorder and ineffective institutional responses erode trust and community pride, reinforcing a negative cycle of decline and inse

Parental Leave and Intimate Partner Violence

By  Dan Anderberg, Line Hjorth Andersen, N. Meltem Daysal, Mette Ejrnæs

We examine the impact of a 2002 Danish parental leave reform on intimate partner violence (IPV) using administrative data on assault-related hospital contacts. Using a regression discontinuity design, we show that extending fully paid leave increased mothers’ leave-taking and substantially reduced IPV, with effects concentrated among less-educated women. The reform also lengthened birth spacing, while separations remained unchanged and earnings effects were modest. The timing and heterogeneity of impacts point to fertility adjustments—rather than exit options or financial relief—as the key mechanism. Parental leave policy thus emerges as an underexplored lever for reducing IPV.

Abnormal Man : Volume 2 - Bibliography

By Arthur MacDonald.

The narrative in Volume 1 asks many pointed questions: What does it mean to be “abnormal”? Who decides? And how have these judgments shaped modern science, education, and criminal justice?

First published in 1893, Arthur MacDonald’s Abnormal Man is one of the earliest American attempts to systematically study human difference through the emerging tools of psychology, anthropology, and criminology. Drawing on international research—from European criminal anthropology to American child-study movements—MacDonald sought to classify the physical, mental, and moral traits considered “aberrant” in his era. His work reflects the hopes and anxieties of a society confronting rapid industrialization, immigration, social change, and new scientific approaches to crime and mental health.

To the modern reader, Abnormal Man reveals both the ambition and the pitfalls of nineteenth-century science. Its pages contain pioneering observations about child development, deviance, and social responsibility, alongside early theories—now discredited—about heredity, physiognomy, and race. What emerges is a vivid and sometimes unsettling portrait of a culture striving to understand human variation without the benefit of modern psychology or ethical safeguards.

The Read-Me.org edition Volume 1 presents Abnormal Man as both a historical artifact and a gateway to critical reflection. It illustrates how scientific thought evolves, how cultural bias can shape research, and how early debates about abnormality laid the groundwork for contemporary approaches to mental health, special education, criminology, and social policy. To make such work, much of it controversial then as it is today, minimally believable, requires extensive documentation. The voluminous Bibliography of Abnormal Man reproduced here in Volume 2, contains all that Macdnald referred to within his detailed exposition. To some, his arguments may seem unsupported, or lacking in evidence. But he left no stone untuned as this amazing bibliographical documentation of all relative contemporary research

A foundational text at the crossroads of science and society, Abnormal Man invites readers to explore the origins of modern debates about deviance, diversity, and the boundaries of the “normal.”

Carceral Citizenship in Puerto Rico: Self-Help and Punishment

By Caroline Mary Parker

The predominant criminological view of ‘carceral citizenship’ takes citizenship as a purely juridical matter, overlooking key social dimensions of citizenship as a human practice. To understand how the carceral turn is reconfiguring citizenship in Puerto Rico, I explore how formerly incarcerated people carve out a place for themselves in Puerto Rican society under the shadow of the prison. Focusing on one couple and their efforts to operate a therapeutic community, I show how self-help supplies a subset of former prisoners with a publicly recognized form of social belonging. Though more stable and encompassing than the stigmatized exile that awaits many people returning from prison, this carceral citizenship invites formerly incarcerated people to assume critical roles in the confinement, punishment, and care of people convicted of drug offences. Overall, this article highlights how self-help and punishment have emerged as intertwined mediums through which formerly incarcerated people assert their citizenship.

Examining the Effects of Firearm Lethality and Aggressors’ Intentions to Kill on Injurious Firearm Violence at American Schools: A research note

By Brent R. Klein,  Cory Schnell,  Steven M. Chermak,  Joshua D. Freilich

This study examined firearm lethality and lethal intent on injurious fatal and nonfatal school shootings using data from The American School Shooting Study, which covers 329 school shootings in the United States from 1990 to 2016. We developed a new multidimensional construct for measuring determination to kill and examined firearm characteristics while considering confounding factors. We identified 11 distinct categories of shooters’ intent, with most showing a strong desire to kill. Both intent and weapon lethality significantly impacted school shooting homicides. Overall, we recommend that prevention and theoretical models should address both factors.

Briefing - Violence and intimidation against politicians in the EU - 15-10-2025

By Lonel Zamfir

Increased political polarisation has led to a proliferation of attacks against elected representatives, political candidates and party members. Verbal abuse and insults, harassment, threats and intimidation, as well as smear campaigns against politicians, occur regularly both online and offline, marking a serious degradation in the quality of political debate in the EU. During the 2024 European elections campaign, there were serious incidents in several countries. Nevertheless, acts of physical violence remain isolated and less frequent in the EU than in many other parts of the world. Violence is a risk to which politicians have always been exposed, including in democratic regimes. Organised crime and radicalised individuals or groups resort to violence to promote their political or economic agendas. EU countries have been unevenly affected; violence linked to organised crime has particularly affected certain regions, especially southern Italy, where it has proven difficult to eradicate. By contrast, violence driven by political radicalisation is a more recent phenomenon and increasingly affects all EU countries – albeit to varying degrees – and tends to flare up during periods of heightened tension, such as election campaigns and large-scale public protests. The impact on political debate, free exchange of opinions and compromise-building is profoundly negative. Violence and intimidation pressure politicians to self-censor when addressing politically sensitive issues and, in some cases, to step out of politics altogether. To counter this, several EU countries have adopted preventive and protective measures, including regular data collection. Examples include classifying offences against elected representatives as aggravated offences, simplifying reporting, and providing training, counselling and emergency assistance. Parliaments have also promoted civility and mutual respect in debates through codes of conduct and have established support services such as legal aid

The Mark or Trace of a Criminal Record: A Survey Experiment of Race and Criminal Record Signaling

By Sarah Lageson and Robert Apel

Employment discrimination from a criminal record is a salient social fact, evidenced by a robust body of experimental research. In Part 1 of this study, we analyze prior criminal record hiring experiments—comprising in-person audits, online audits, and opt-in surveys—to describe patterns over time in employer receptivity to applicants of different races with criminal records. In Part 2, we use a novel experimental survey of 1080 employers to measure how differences in the signaling of a criminal record impact the criminal record–employment relationship. Our results reveal a substantial hiring penalty for an official criminal record (conveyed by a background check report), with a smaller but still significant penalty for an unofficial criminal record (an Internet search engine “hit”). The experiment also shows that the official criminal record penalty is significantly larger for White applicants than for Black applicants. Although the latter finding was counter to expectations informed by prior studies, it is less surprising considering our Part 1 findings, which reveal a closing racial gap in the criminal record penalty during the last 20 years. We discuss how broader legal, social, and technological changes, as well as changes in methodologies, impact our understanding today of criminal records, race, and employment.

Violence-Informed Approaches to Preventing Criminalisation in the UK Evidence, Research, Policy, Practice, and Emerging Thinking

By Stan Gilmour

This briefing paper examines the emerging framework of "violence informed approaches" as a critical development in understanding and responding to violence, particularly in the context of preventing criminalisation in the UK. Traditional approaches to violence prevention have often focused on individualised explanations, frequently obscuring the broader social, political, and economic contexts in which violence occurs. Whilst trauma-informed approaches have gained significant traction, they have been critiqued for sometimes inadvertently pathologising  individuals and focusing on psychological impacts rather than addressing structural causes. Violence-informed approaches build upon and extend these frameworks by offering a more explicitly political and contextual analysis of violence and its social determinants. This briefing draws on the foundational work of Professor Stan Gilmour (2025) on violence-informed approaches to preventing criminalisation¹⁶, integrating this with current evidence, research, policy, and practice in the UK to outline the theoretical underpinnings, key characteristics, and practical applications of this emerging framework.

Indigenous Youths’ Strain and Delinquency: Investigating the Individual and Cumulative Impact of Strain Through a Cultural Lens

By Makayla Burden; Ariel L. Roddy

Using General Strain Theory as a framework, this study examines the direct effects of seven categories of strain that fall under three broad domains, negative emotions, and substance use on Indigenous youths’ delinquency. Additionally, the cumulative impact of experiencing more than one domain or category is evaluated. Cultural connectedness and support systems are assessed as potential protective factors. Using a sample of Indigenous youth (N = 359) in the United States, this study employs multiple imputation, correlations, and stepwise negative binomial regressions to address the research questions. Results show that few individual strain domains and categories were significant predictors of delinquency. However, there was a cumulative effect of strain where, as the number of domains or categories experienced increases, so did the likelihood of delinquency. Negative emotions were not associated with delinquency and there was limited support for cultural connectedness and support systems’ ability to buffer against delinquent behaviors. Finally, substance use was strongly associated with delinquency. Therefore, there is merit in using the GST framework to examine Indigenous youth delinquency through a cultural lens. However, more culturally integrated research needs to be conducted to fully understand Indigenous youth’s strain and delinquency, and what should be done to provide further support.

When Rule-Breaking Spreads: The Social Contagion of Prosocial Deviance in the Workplace

By Takashi Mitsuhashi, Hitoshi Mitsuhashi, Masahiko Urao

Rule-breaking, a significant workplace safety threat, is often shaped by social influences, with employees more likely to engage in violations when exposed to similar behaviors among peers. Prior research has largely treated peer rule-breaking as uniformly influential, overlooking how situational factors and the perceived motives behind violations shape contagion effects. This study examines how peer effects influence employees’ rule-breaking behaviors, particularly when employees are exposed to peers’ rule-breaking in situations where these actions can plausibly be inferred as motivated by prosocial motives. Using longitudinal task-level data on nurses’ rule-breaking during medication administration at a medical facility in Tokyo, we find that a nurse is more likely to break patient identification rules when exposed more to rule-breaking by co-shift peers, especially when exposed in situations where the nurse can infer peers’ prosocial motives. In addition, we also find that peer effects diminish when management policies reduce nurses’ exposure, particularly by transitioning from pair-checking to single-checking procedures. These insights contribute to research on workplace safety and policy interventions to manage deviant behaviors.

From Gray to Black Markets – A Quasi-Experimental Study on Algorithmically Driven Digital Drift Opportunities on Social Media

By Kristoffer Aagesen & Jakob Deman

This study examines how Snapchat’s recommendation algorithms facilitate digital drift from legal to illegal activities. Using microsociological observations, we conducted a quasi-experiment with 40 profiles that engaged with gray markets for nicotine vapes and sex work. Within four days, 65% of these profiles were directed to illicit drug sellers, despite no prior engagement with illegal content. Our audit of Snapchat’s affordances highlights their criminogenic potential, showing how platform algorithms can actively steer users toward illicit networks. These findings underscore how social media platforms function not only as offender convergence spaces but also as facilitators of illegal activity.

“I’m Not a Serial Killer:” Exploring Identity and Boundary-Setting in the Narratives of a Serial Homicide Offender

By Karen Holt

A dearth of research examines the perceptions of serial homicide offenders directly through qualitative interviews. The current study presents a case study analysis of serial homicide offender, Harold David Haulman. The concept of serial homicide as understood by the offender himself is explored, with the focus on what it means to be a “serial killer” and the acceptance or rejection of that label. Findings revealed that Haulman both actively resists stigma while at times leaning into the “serial killer” label, a label he constructs by drawing from the popular criminological and larger cultural narratives of serial murder.

A Systematic Review of Literature on Substance Use in Nightlife Settings Utilizing In Situ Data Collection

By Renata Glavak-Tkalić, Mike Vuolo, Anja Wertag

Background: Nightlife environments, including nightclubs, bars, and entertainment districts, are associated with elevated substance use and related harms. In situ nightlife studies offer an opportunity to capture real-time data on substance use from targeted populations. Despite the growing number of studies, no systematic review has yet been conducted on this topic. Therefore, the aim of this systematic review is to explore empirical in situ research in nightlife settings, with a focus on substance use. Methods: A systematic search was conducted across four databases (WOS, PsycInfo, PubMed, and Google Scholar) for English-language peer-reviewed journal articles published between 2014 and 2023 that involved in situ primary data collection about substance use in nightlife settings. In total, 55 articles met the inclusion criteria. Detailed data were extracted on various aspects, such as study design, recruitment methods, substances reported, and key findings. Results: Included studies represented the United States, Europe, Brazil, and Oceania. Most (93%) employed surveys; over half (56%) also collected biomarkers. Substance use was highest among males, young adults, and sexual minorities, with polydrug use and high-risk behavior particularly prevalent in Electronic Dance Music scenes. Included articles varied substantially in their focus, including prevalence, correlates, patterns, harms, and interventions. Recruitment and reporting methods varied widely, complicating cross-study comparisons. Conclusions: This review highlights both the value and challenges of in situ research. Biomarker data enhance the reliability of self-report measures, while inconsistent reporting and non-random sampling limit generalizability. Future research should adopt standardized reporting guidelines that would allow for stronger evidence, permit reproducibility, and increase transparency

Violence at School

By Losefa Aguirre, Fernanda Ramírez-Espinoza, Roman Andres Zarate

This paper estimates the impact of violence perpetrated by peers and school staff on student victims. Leveraging unique administrative data from Chile that links reports of school violence to individual educational records, we address longstanding data limitations that have constrained empirical research on this issue. Using a matched difference-in-differences design, we find that exposure to school violence has persistent negative effects: absenteeism increases by 46–64%, grade retention rates double, and both grades and test scores decline significantly, with impacts lasting up to four years. In the longer term, victims are substantially less likely to graduate from high school or enroll in university, with violence perpetrated by adults having more severe consequences than peer violence. Complementary survey evidence reveals that reported incidents are associated with increased perceptions of violence and discrimination, as well as decreases in school belonging and teacher expectations. While these psychological and perceptual effects tend to fade after one year, the adverse educational consequences persist, underscoring how brief traumatic experiences can lead to long-lasting educational disadvantages.

Taking Stock: Counting the Economic Costs of Alcohol Harm

By Jamie O’Halloran and Sebastian Rees

Most people are aware of the health risks of drinking alcohol. Alcohol is known to cause at least seven types of cancer and to be a primary risk factor for more than 30 health conditions. The more alcohol someone drinks, the greater the risk. Despite this, alcohol consumption across the UK remains worryingly high.

The most important fact in this report is that after some years when alcohol consumption was going down in the UK, the trend is now heading in the wrong direction and the health risks are clear. Increased rates of alcohol consumption can already be detected in the rise in both alcohol-related and alcohol-specific mortality since 2019. For example, in 2023, 10,473 people died from alcohol-specific causes in the UK, the highest number on record.

Inequalities

As well as having a deleterious effect on the nation’s health as a whole, harmful levels of alcohol consumption are also a key driver of health inequalities. The health burden of alcohol harm is not spread equally across the UK – people living in Scotland, Northern Ireland and Wales are more likely to die of alcohol-specific causes than those living in England. 

Impact on the workforce

Leaving aside, for the moment, the impact of people developing onset of chronic health conditions such as cancer, cardiovascular disease and anxiety and depression, which often lead to people leaving the labour market, alcohol consumption also has significant effects on the productivity of those in work. It can increase both:

  • absenteeism, where people take time off due to illness and

  • presenteeism, where people are at work but their capacity is reduced.

Previous analysis by the Institute of Alcohol Studies estimates that alcohol consumption costs the economy £5.06 billion a year – with 44 per cent of the cost being due to presenteeism.

The current report builds on existing analysis and takes a closer look at the relationship between alcohol consumption and workforce productivity by using data from Understanding Society – a large longitudinal panel survey of UK households – and findings from a specially commissioned survey, the authors examine alcohol’s economic impact more deeply, including its varied impacts on different sectors of the economy and job roles.

Key findings

  • A quarter of employees feel pressure to drink at workplace events, rising to 38 per cent of 18 to 24 year olds

  • Workplace drinking culture driving absences as 31 per cent of workers call in sick in past year after work events

  • IPPR calls for minimum unit pricing, reintroducing the alcohol duty escalator, and stronger action from employers

The authors say that pressure to drink at work events is contributing to widespread alcohol-related absences and reduced productivity across all sectors.  

From after-work drinks to subsidised bar tabs at company events, alcohol is often embedded in professional life. A quarter (24 per cent) of workers said they sometimes felt pressured to drink when they didn’t want to, rising to 38 per cent among younger employees (aged 18-24). Over a third said drinking at work events excluded non-drinkers or created cliques.

This culture is driving real consequences. One in three UK workers (31 per cent) have called in sick in the past year after drinking at work-related events, while 22 per cent reported working while hungover, and 29 per cent observed colleagues being tired or sluggish after drinking.

Interestingly, young workers and senior executives are among the most affected groups.
