García-Pérez Á, Krotter A, Aonso-Diego G. The impact of gambling advertising and marketing on online gambling behavior: an analysis based on Spanish data. Public Health 2024; 234:170-177. [PMID: 39018681 DOI: 10.1016/j.puhe.2024.06.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 06/13/2024] [Accepted: 06/17/2024] [Indexed: 07/19/2024]
Abstract
OBJECTIVES Online platforms have transformed gambling into a daily activity for many, raising concerns about its potential harm. Notably, marketing strategies play a crucial role in influencing gambling behaviors and normalizing gambling. This study aims to explore the relationship between monthly marketing expenditure by the gambling industry, the online amount of money bet, and the number of online accounts (active and new) in Spain. A secondary goal is to assess the impact of marketing restrictions under the Spanish Royal Decree 958/2020 on the relationship between marketing and online gambling behavior. STUDY DESIGN Longitudinal study. METHODS Data covering January 2013 to December 2023. Dependent variables included: new accounts, active accounts, gambler deposits, and the total money bet. Independent variables included: expenditure on advertising, bonuses, affiliate marketing, and sponsorship. A Seasonal Autoregressive Integrated Moving Average (SARIMA) model was employed to assess marketing's impact on online gambling behavior. RESULTS Findings show that investment in advertising (P ≤ 0.025), promotions (P < 0.001), and sponsorships (P ≤ 0.004) significantly increase the number of new and active accounts, deposits, and total money bet. For instance, it has been estimated that, for every €1 invested in bonuses and sponsorship, gamblers deposit €1.6 and €4 into their accounts, respectively. Moreover, the Spanish law regulating gambling advertising has seemingly weakened the link between marketing expenditure and gambling behavior, with the notable exception of bonuses, where the impact has intensified. CONCLUSIONS These results underline the importance of ongoing monitoring and regulation of gambling behavior in Spain, emphasizing the need for strict adherence to regulations.

Abstract
BACKGROUND AND AIMS This is the first nation-wide register study based on a total population sample measuring the gender-specific incidences of chronic diseases and conditions among adults diagnosed with gambling disorder (GD). DESIGN, SETTING AND PARTICIPANTS The study used aggregated data for 2011-22 retrieved from the Register of Primary Health Care visits, Care Register for Health Care and Care Register for Social Welfare, including specialized outpatient and inpatient health care, inpatient social care and institutional care and housing services with 24-hour or part-time assistance, set in mainland Finland. Participants comprised people aged 18-90+ years with GD diagnosis [corresponding to pathological gambling, International Classification of Diseases 10th revision (ICD-10) code F63.0, n = 3605; men n = 2574, women n = 1031] and the general population (n = 4 374 192). MEASUREMENTS Incidences of somatic diseases and psychiatric disorders were calculated for the people with diagnosed GD and for the general population, separately for women and men. FINDINGS After standardizing for age, the incidence of each diagnostic group was systematically higher for people with GD compared with the general population, except for cancer. The highest standardized incidence ratio (SIR) values were for psychiatric disorders [SIR = 234.2; 95% confidence interval (CI) = 226.1-242.4], memory disorders (SIR = 172.1; 95% CI = 119.1-234.8), nervous system diseases (SIR = 162.8; 95% CI = 152.8-173.1), chronic respiratory diseases (SIR = 150.6; 95% CI = 137.6-164.2), diabetes (SIR = 141.4; 95% CI = 127.9-155.5) and digestive diseases (SIR = 134.5; 95% CI = 127.1-142.2). CONCLUSIONS In Finland, the incidence of chronic diseases and conditions among people with gambling disorder is higher compared with the general population, apart from cancer.

Abstract
Armed forces veterans are especially prone to experiencing a variety of addictive disorders, including gambling disorder. Even so, gambling disorder in veterans remains understudied generally, and there remain significant gaps in the research literature with regards to how gambling disorder relates to the experience and expression of comorbid substance use disorders. The present work examines the prevalence, presentation, and clinical associations of substance use disorders in U.S. Armed Forces veterans receiving inpatient treatment for gambling disorder. Participants (N = 664) were veterans from all branches of the U.S. Armed Forces receiving inpatient treatment for gambling disorder through the Department of Veteran Affairs Healthcare System. Clinical data from the time of intake was analyzed. A substantial portion of veterans (36.1%) met current criteria for an SUD, with another 16.5% reporting a history of SUD. Alcohol use disorder was the most commonly reported SUD (76.1% of those with a current SUD), with polysubstance use disorders and stimulant use disorders each occurring in at least 25% of those with SUDs. SUD status was related to greater levels of impulsivity, but there was no evidence that SUD status was related to gambling symptom severity, gambling preferences, or further psychiatric comorbidities.

The risk and development of work disability among individuals with gambling disorder: a longitudinal case-cohort study in Sweden. Psychol Med 2024; 54:1391-1402.

Abstract
BACKGROUND This longitudinal register study aimed to investigate the association between gambling disorder (GD) and work disability and to map work disability in subgroups of individuals with GD, three years before and three years after diagnosis. METHODS We included individuals aged 19-62 with GD between 2005 and 2018 (n = 2830; 71.1% men, mean age: 35.1) and a matched comparison cohort (n = 28 300). Work disability was operationalized as the aggregated net days of sickness absence and disability pension. Generalized estimating equation models were used to calculate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for the risk of long-term work disability (>90 days of work disability/year). Secondly, we conducted Group-based Trajectory Models on days of work disability. RESULTS Individuals with GD showed a four-year increased risk of long-term work disability compared to the matched cohort, peaking at the time of diagnosis (AOR = 1.89; CI 1.67-2.13). Four trajectory groups of work disability days were identified: constant low (60.3%, 5.6-11.2 days), low and increasing (11.4%, 11.8-152.5 days), medium-high and decreasing (11.1%, 65.1-110 days), and constant high (17.1%, 264-331 days). Individuals who were females, older, with prior psychiatric diagnosis, and had been dispensed a psychotropic medication, particularly antidepressants, were more likely to be assigned to groups other than the constant low. CONCLUSION Individuals with GD have an increased risk of work disability which may add financial and social pressure and is an additional incentive for earlier detection and prevention of GD.

Changes in some health and lifestyle behaviours are significantly associated with changes in gambling behaviours: Findings from a longitudinal New Zealand population study. Addict Behav 2024; 149:107886.

Abstract
Although a large number of studies have investigated associations between risky gambling behaviours and health, lifestyle and social factors, research has not focused on changes in these factors and associations with changes in gambling risk level. This study utilised existing data from the four waves of the longitudinal New Zealand National Gambling Study to examine associations between changes in substance use, mental and physical health, and quality of life and deprivation with changes in gambling risk level over time. A Markov chain transition model was used to perform these analyses using data from participants who had completed all four waves (11,080 data transitions). Although changes in various covariates were associated with changes in all gambling risk levels, the highest number of significant factors was for transitioning into risky gambling from non-problematic gambling, including development, or continuation, of several negative health and lifestyle factors that may possibly be alleviated by transitioning out of risky gambling. These findings highlight the importance of screening for gambling behaviours when assisting people with substance use, health issues, or social situations or conditions in order to provide appropriate and effective social, health and treatment supports for people whose gambling behaviour increases over time.

Abstract
BACKGROUND Both psychostimulant use and engagement with probabilistic schedules of reward sensitize the mesocorticolimbic dopamine (DA) system. Such behaviors may act synergistically to explain the high comorbidity between stimulant use and gambling disorder. The salient audiovisual stimuli of modern electronic gambling may exacerbate the situation. METHODS To probe these interactions, we sensitized ventral tegmental area DA neurons via chronic chemogenetic stimulation while rats (n = 134) learned a rat gambling task in the presence or absence of casino-like cues. The same rats then learned to self-administer cocaine. In a separate cohort (n = 25), we confirmed that our chemogenetic methods sensitized the locomotor response to cocaine and potentiated phasic excitability of ventral tegmental area DA neurons through in vivo electrophysiological recordings. RESULTS In the absence of cues, sensitization promoted risk taking in both sexes. When rewards were cued, sensitization expedited the development of a risk-preferring phenotype in males while attenuating cue-induced risk taking in females. CONCLUSIONS While these results provide further confirmation that ventral tegmental area DA neurons critically modulate risky decision making, they also reveal stark sex differences in the decisional impact that dopaminergic signals exert when winning outcomes are cued. As previously observed, risky decision making on the cued rat gambling task increased as both males and females learned to self-administer cocaine. The combination of DA sensitization and win-paired cues while gambling led to significantly greater cocaine taking, but these rats did not show any increase in risky choice as a result. Therefore, cocaine and heavily cued gambles may partially substitute for each other once the DA system has been rendered labile through sensitization, thereby compounding addiction risk across modalities.

Abstract
Gambling disorder and cannabis use disorder are both considered major public health issues. Despite the well-documented frequency of substance use disorders among people with gambling disorder, little is known about the experiences of those who both engage with gambling and cannabis. A scoping review was undertaken to investigate studies focusing on the experiences of people who gamble and use cannabis. Unexpectedly, no qualitative or mixed-methods studies that included an in-depth qualitative component to study the lived experiences of this population were found. This absence highlights the critical need to diversify research methods and fill the gap in knowledge of the lived experiences of people who both gamble and consume cannabis.

Abstract
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. Methods A study with a longitudinal design using objective registry data drawn from the Norwegian Patient Registry was carried out. Among the patients with a registered diagnosis of GD between 2008 and 2018 (N = 5,131; males = 81.8%), those (who in addition) had a registered diagnosis of any SUD (n = 1,196; males = 82.1%) were included. The measures included a registered diagnosis using the ICD-10 of both GD (code F63.0) and SUDs (codes F10-F19) by a health care professional. Binomial tests were used to identify the temporal order between SUD(s) and GD. Co-occurring cases (i.e., cases diagnosed within the same month) were removed in the main analyses. Results Results showed a significant directional path from SUD to GD but no support for the reversed path (i.e., from GD to SUD). This finding was similar overall for (i) both males and females, (ii) when different SUDs (alcohol, cannabis, sedatives, and polysubstance) were examined individually, and (iii) when specifying a 12-month time-lag between diagnoses. Conclusions The findings suggest that experiencing SUD(s) is a risk marker for GD given the temporal precedence observed for patients in specialised healthcare services seeking treatment. These results should be considered alongside screening and prevention efforts for GD.

Abstract
Epidemiological and phenomenological studies suggest shared underpinnings between multiple addictive behaviors. The present genetic association study was conducted as part of the Psychological and Genetic Factors of Addictions study (n = 3003) and aimed to investigate genetic overlaps between different substance use, addictive, and other compulsive behaviors. Association analyses targeted 32 single-nucleotide polymorphisms, potentially addictive substances (alcohol, tobacco, cannabis, and other drugs), and potentially addictive or compulsive behaviors (internet use, gaming, social networking site use, gambling, exercise, hair-pulling, and eating). Analyses revealed 29 nominally significant associations, from which, nine survived an FDRbl correction. Four associations were observed between FOXN3 rs759364 and potentially addictive behaviors: rs759364 showed an association with the frequency of alcohol consumption and mean scores of scales assessing internet addiction, gaming disorder, and exercise addiction. Significant associations were found between GDNF rs1549250, rs2973033, CNR1 rs806380, DRD2/ANKK1 rs1800497 variants, and the “lifetime other drugs” variable. These suggested that genetic factors may contribute similarly to specific substance use and addictive behaviors. Specifically, FOXN3 rs759364 and GDNF rs1549250 and rs2973033 may constitute genetic risk factors for multiple addictive behaviors. Due to limitations (e.g., convenience sampling, lack of structured scales for substance use), further studies are needed. Functional correlates and mechanisms underlying these relationships should also be investigated.
