Telecommunications Network Measurements of Online Gambling Behavior in Switzerland: A Feasibility Study.

BACKGROUND: Methodological shortcomings of gambling studies relying on self-report or on data sets derived from gambling operators tend to result in biased conclusions. The aim of this study was to analyze online gambling behavior using a novel network database approach. METHODS: From October 13 to October 26, 2014, telecommunications network data from a major telecommunications provider in Switzerland were analyzed. Netflows between mobile devices and a poker operator were quantified to measure the gambling duration and session number. RESULTS: Time spent gambling during night and working hours was compared between devices with longest (red group), intermediate (orange group), and shortest gambling time (green group). Online gambling behavior differed depending on overall gambling time, F (2, 3,143). Night and working hours gambling was the highest in the red group (53%), compared to the orange (50.1%) and the green groups (41.5%). Post hoc analyses indicated significant differences between the orange and green groups (p < 0.05). No differences were observed between the red and orange groups (p = 0.850), and the red and green groups (p = 0.053). CONCLUSIONS: On mobile devices, distinct gambling patterns were observed depending on the overall gambling time. This methodology could also be used to investigate online gaming, social media use, and online pornography.

A stabilizing factor?-Video gaming among elite athletes during the first lockdown of the COVID-19 pandemic.

Objectives: Little is known about the extent of video gaming among elite athletes, specifically under stressful conditions like those induced by the current COVID-19 pandemic. The aim of this study was to evaluate the intensity and extent of video gaming in the context of the COVID-19 pandemic, during which the usual daily routine of many athletes was disrupted. Methods: Overall, 203 elite athletes from Switzerland who participated in Olympic sports or in "International Olympic Committee"-approved disciplines were interviewed using an online questionnaire. They were questioned on their video game consumption during the first Swiss lockdown during the COVID-19 pandemic as well as on their athletic performance and economic circumstances. Additionally, mental and physical health were assessed by standardized questionnaires. From this questionnaire data, predictors of gaming time were evaluated using multivariable analysis. Results: Before the lockdown, 21% of the participating athletes played video games regularly. The average playing time was 15.8 h per month within the gamer group. During the first lockdown, 29% of athletes reported gaming regularly, and within the gamer group the average gaming time increased significantly, by 164%. The mental health burden showed significant differences between gamers and non-gamers regarding existential fears during the lockdown, the ability to cope with governmental measures due to COVID-19 and total sleeping time. However, there was no statistical difference in respect to standardized scales for depressive symptoms, sleep behavior, and anxiety. Higher video gaming time during the lockdown was significantly associated with male gender and previous gaming before the COVID-19 lockdown. Conclusion: Video gaming time increased significantly during the first lockdown. Whether video gaming among elite athletes hereby functions as an effective coping behavior remains to be shown and requires more research.

Use of psychotropic substances among elite athletes - a narrative review.

BACKGROUND AND AIMS: Elite athletes may use psychotropic substances for recreational reasons, (perceived) performance enhancement or self-medication. Causes can overlap. For athletes, substance use may be associated with various medical and social risks. Psychoactive substances include alcohol and nicotine, illicit and various prescription drugs, which all have a potential for abuse and dependence. This paper reviews the existing literature on the use of psychoactive substances and associated substance use disorders among elite athletes in terms of prevalence, patterns of use, as well as underlying causes and risk factors. METHODS: Due to the heterogeneous and partially fragmentary study data, a narrative approach with selection of applicable publications of a Medline search was chosen. RESULTS: The most commonly used psychoactive substances among elite athletes were alcohol, nicotine, cannabis, stimulants and (prescription) opioids. Overall consumption rates are lower in professional sports than in the general population, but use of several substances (smokeless tobacco products, prescription opioids, stimulants) have high prevalence in specific sports and athlete groups. Substance use is subject to multiple risk factors and varies by substance class, sport discipline, country and gender, among other factors. CONCLUSION: Knowledge on the underlying causes and patterns of substance use, as well as the prevalence of substance use disorders in professional sports, is still limited. High prevalence of various substances (i.e., nicotine, prescription opioids) may indicate potentially harmful patterns of use, requiring further research. Specific preventive and therapeutic concepts for the treatment of substance use disorders in elite athletes should be developed.

Cannabis use in Switzerland 2015-2045: A population survey based model.

BACKGROUND: Alternative cannabis regulation models are discussed and implemented worldwide. A baseline scenario under the assumption of no policy or market changes may prove useful to forecast cannabis use and treatment demand and evaluate changes in legislation. METHODS: Based on data of the Continuous Rolling Survey of Addictive Behaviours and Related Risks on cannabis use, age, gender and nationality from 2011 to 2015, we used general estimating equation analysis to model lifetime and 30-days prevalence from 2015 to 2045 in Switzerland accounting for demographic trends. RESULTS: Lifetime prevalence of cannabis use is projected to grow from 28.3% (CI 95% 27.8-28.8) in 2015 to 42.0% (CI 95% 41.0-43.0) in 2045. 30-days prevalence would increase slightly from 2.70% (CI 95% 2.53-2.88) to 3.39% (CI 95% 3.11-3.66). Due to population growth, absolute numbers with past 30-day cannabis use are estimated to increase from 202,784 (CI 95% 189,534-216,035) to 314,302 (CI 95% 288,504-340,100). Among those aged under 30 years no substantial change in lifetime and 30-days prevalence of cannabis use is projected. Larger changes are estimated to occur in the age group 30+. The mean age of past 30-day cannabis users would increase for men with Swiss nationality from 30.3 to 38.7 years. DISCUSSION: Population-based survey data and demographic projections can be used to develop baseline scenarios of future cannabis use. Assuming no changes in cannabis legislation, growing absolute numbers of users will likely increase treatment demand. Cannabis use is estimated to increase among the group aged >30 years, which is currently underrepresented in clinical treatment and research. Our findings highlight the need for prospective baseline scenarios to evaluate the impact of legislative changes on cannabis use. Moreover, in Switzerland effective prevention and treatment interventions for cannabis use disorders are required even if cannabis legislation remains unchanged.

[Substance abuse in older adults]. / Sucht im Alter.

In respect of demographic change, the number of older patients with substance abuse and addiction is on the raise. In this review we present important clinical and therapeutic aspects of substance abuse and addiction in the elderly and focus on alcohol, benzodiazepines and opioids. Daily and risky alcohol consumption is common among older people. They also have an increased risk getting alcohol-related complications. For early detection, laboratory parameters and questionnaires such as the AUDIT-C are suitable. Therapeutically brief interventions have been proved successful. Also, abuse of benzodiazepines, especially low-dose addiction, is widespread among older persons, although often overlooked, and patients often do not recognize their addiction. The physician has to know the correct indication, adequate dosage and pharmacological interactions. A slow-dose reduction is recommended in case of addiction. Thanks to opioid substitution therapy, patients with an opioidaddiction can reach a higher age. Age influences the effects of the substitute, which may require an adjustment of the dosage. Treatment of elderly patients should be based on their needs and resources and is usually very effective.

Sur le plan démographique le nombre de personnes âgées abusant ou dépendant de substances est en augmentation. Dans cette revue seront présentés des aspects cliniques et thérapeutiques de l'abus et de la dépendance de substances dans cette classe de la population, en particulier en ce qui concerne l'alcool, les benzodiazépines et les opioïdes. La consommation d'alcool quotidienne est fréquente chez les personnes âgées et augmente chez elles le risque de complications. Pour la détection précoce d'un abus d'alcool des paramètres de laboratoire et des questionnaires comme le AUDIT-C sont appropriés. Des interventions thérapeutiques brèves se sont avérées efficaces. L'abus de benzodiazépines, en particulier la dépendance à ces substances à petites doses, est aussi très répandu et souvent négligé chez les personnes âgées, de telle sorte que ces dernières n'en ont pas conscience. Le médecin doit connaître l'indication correcte, le dosage adéquat et les interactions des benzodiazépines. Une réduction lente des doses est recommandée en cas de dépendance. Les patients présentant une dépendance aux opioïdes ont leur vie prolongée grâce à un traitement substitutif. L'âge influence les effets des substances substitutives, ce qui peut nécessiter des adaptations de dosage. Le traitement des personnes âgées devrait être basé sur leurs besoins et leurs ressources. Il est généralement très efficace.
