Breath alcohol concentration, hazardous drinking and preloading among Swedish university students

Changes in patterns of alcohol consumption in young psychiatric outpatients: two comparable samples assessed with 10 years apart

AIMS

Over the past 20 years, a trend towards non-drinking and less use of alcohol has been reported among young adults. This study aimed to investigate if a similar trend in alcohol consumption can be seen among young adult psychiatric outpatients.

METHODS

This was a cross-sectional study based on two comparable samples of young adult (18-25 years) psychiatric outpatients recruited approximately 10 years apart in 2002-2003 (N = 197) and 2012-2016 (N = 380). The Swedish version of the Alcohol Use Disorders Identification Test (AUDIT) was used to assess alcohol consumption. Psychiatric diagnoses were based on diagnostic interviews. Differences between the two samples in alcohol consumption and a number of alcohol-use disorder diagnoses were analysed. Cramer's V was chosen as the effect size measure.

RESULTS

Mean AUDIT scores and prevalence of diagnosed alcohol-use disorder in the two samples did not differ significantly. The number of non-drinkers was larger among patients in the mid-2010s (15.8% vs. 8.1%; χ2 = 6.76, p < 0.01, Φ = 0.11), but when non-drinkers were excluded, the alcohol consumption was higher among females in the later sample.

CONCLUSION

The mean level of alcohol consumption seems not to have changed to the same extent among young psychiatric patients as in the general population. However, some young psychiatric patients have followed the trend of non-drinking, while others consume more alcohol. Further studies on both non-drinking and high alcohol consumption in psychiatric patients are needed to understand their mechanisms.

Mental health, self-rated health, risky sexual behaviour, alcohol use, and drug use among students who intend to spend a semester abroad - a cross-sectional study

Aim

Our aim was to investigate potential differences in mental health, self-rated health, risky sexual behaviour, alcohol use, and drug use between (1) Prospective exchange students and campus students separated by sex, and (2) male and female students as a group.

Method

Comparative cross-sectional design using an online survey containing the following instruments: Knowledge, Attitudes, and Sexual Behaviour in Young People in Sweden; Self-Rated Health Questionnaire; and General Health Questionnaire 12. One-hundred and fourteen prospective exchange students and 451 campus students participated in the study.

Results

Male prospective exchange students rated their mental health as being better and had used cannabis more often compared with female prospective exchange students. Male prospective exchange students also rated their mental health as being better than male campus students. Female students, in general, rated their mental health as worse than male students. A larger proportion of male prospective exchange students had sex together with alcohol compared with male campus students, and a larger proportion of female prospective exchange students had sex with a new partner and drank more alcohol compared to female campus students.

Conclusion

The result shows that risky alcohol use and sexually risky behaviour is prominent amongst prospective exchange students. It is possible that they will continue, and even increase their risky behaviour whilst abroad as they find themselves in a new social context, and free from influence of the rules and restrictions that they might have at home. With limited knowledge of the local culture, native language, and in an unfamiliar environment, it is possible that the risks will be enhanced and possibly decrease their health. This highlights the need for proactive interventions, conceivably with some variations in content between sexes.

Student drinking cultures in tertiary education residential accommodation: A contextual research study

Background: In Australia, harmful drinking among students aged 18-24 years in tertiary education residential accommodation (TRA) remains high, placing students at higher risk of harms than non-TRA and university peers. Aim: The aim of this study was to identify the context-specific factors distinctive to TRAs that supported a heavy drinking culture among students. Conducted across three sites in Melbourne, Australia, the purpose of the study was to inform the development of context-specific harm reduction interventions for these sites. Methods: Five focus groups were conducted with 32 students to examine their lived experience of drinking within the distinctive environments of their TRAs. The data were examined using thematic data analysis. Results: Three themes were identified: (1) routine drinking in TRAs; (2) drinking for social inclusion in the TRA; and (3) TRA alcohol governance and students' self-regulation. The data show that factors contributing to these TRA drinking cultures included: liberty to store alcohol and drink on campus; freshers' belief that admission to the TRA was conditional on "partying hard"; students' belief that staff supported the TRA drinking culture; and poor dissemination and operationalisation of TRA alcohol policy. Collectively, these factors fostered an environment that enabled frequent and heavy alcohol consumption among residents. Conclusions: The TRA drinking cultures were supported by social and regulatory factors specific to these institutions and, in particular, by a liberal approach to TRA alcohol governance and poorly disseminated alcohol policy that made widespread heavy drinking possible. Drinking cultures in TRAs can be changed through appropriate interventions that include nuanced policy and effective governance.

Pre-Loading with Drugs before Entering the Nighttime Entertainment District: A Scoping Review

Background: Nighttime entertainment districts attract many people who pre-load with alcohol and other substances before entering licensed venues. Despite the harms and dangers associated with both alcohol pre-loading and drug use respectively, there is a paucity of research on drug and polysubstance pre-loading. Objectives: The primary objectives of this scoping review are to systematically map out the body of existing literature on drug and polysubstance pre-loading, discuss methodological potentials and pitfalls in field-based research, identify gaps in knowledge, and derive practical implications and opportunities for future research. Methods: Using the PRISMA (ScR) guidelines, we conducted a search of Medline, PsycINFO, Embase, Scopus, CINAHL, Social Services Abstracts, Sociological Abstracts, and Web of Science databases. We followed this up by conducting an author and citation analysis of relevant articles. Results: Of the 632 data sources identified, 338 articles were reviewed after removing duplicates. Overall, only nine articles were included and thematically analyzed. In our review and analysis of the literature, we find people who drug pre-load to be a particularly vulnerable subset of the population. We also posit that the point-of-entry design has greater sensitivity than the commonly used portal-in design. From this, we also draw attention to various time points where field-based researchers can provide intervention. Conclusions: Given the high prevalence of young adults engaging in the behavior, clinicians should consider pre-loading behaviors when assessing for risk and vulnerability. Field-based research would elucidate the full breadth and scope of the growing pre-loading phenomenon and the dangers associated with this practice.

Prologue to the special issue on predrinking and drinking game behaviors among adolescents and young adults in the United States and across the globe: Definitions and overview of prevalence rates

Predrinking and drinking games (DGs) are common risky drinking practices among adolescents and young adults in many different countries around the world. However, most studies on these behaviors have been conducted with university student samples in a limited number of countries. Despite the risks of negative alcohol-related consequences associated with predrinking and DGs, these activities are quite prevalent among young people. In this prologue, we provide definitions for predrinking and DGs and an extensive overview of the known prevalence rates of predrinking and DGs among young people around the world. This special issue addresses known gaps in the literature by including articles which (a) use differing methodologies to examine predrinking or DGs behavior, (b) consider psychosocial and contextual factors that influence these behaviors, and (c) examine young people's perceptions of alcohol policies and interventions. Taken together this Special Issue offers an international view on how and why young people around the world engage in these risky drinking practices, and potential ways to address these behaviors.

Lifestyle behaviors in Swedish university students before and during the first six months of the COVID-19 pandemic: a cohort study

Background

Changes in Swedish university students’ lifestyle behaviors during the COVID-19 pandemic are unknown. This study aimed to assess physical activity, sitting time, meal frequency and risk substance use (alcohol, tobacco, and illicit use of drugs) in Swedish university students before and during the first six months of the COVID-19 pandemic, for all and stratified by age and sex.

Methods

Data were obtained from the Sustainable University Life cohort study in which web-based surveys were sent to university students repeatedly for one year. Baseline assessment (before the pandemic) was between August 2019-March 2020, follow-up 1 (FU1) between March-June 2020, and follow-up 2 (FU2) between June–September 2020. Participants reported weekly minutes of physical activity, daily sitting hours, meal frequency by weekly intake of different meals, and motivation for eating irregularly, if so. Also, harmful use of alcohol, tobacco and illicit drugs was assessed. Population means and differences with 95% confidence intervals (95% CI) in lifestyle behaviors between time points were calculated with Generalized Estimating Equations.

Results

1877 students (73% women, mean age 26.5 years) answered the baseline survey. Weekly exercise decreased by -5.7 min (95% CI: -10.0, -1.5) and -7.7 min (95% CI: -12.6, -2.8) between baseline and FU1 and FU2, respectively. Weekly daily activities increased by 5.6 min (95% CI: 0.3, 11.7) and 14.2 min (95% CI: 7.9, 20.5) between baseline and FU1 and FU2. Daily sitting time decreased by -1.4 h (95% CI: -1.7, -1.2) between baseline and FU2. Breakfast intake increased by 0.2 days per week (95% CI: 0.1, 0.3) between baseline and FU2. Lunch intake decreased by -0.2 days per week (95% CI: -0.2, -0.1) between baseline and FU1 and by -0.2 days per week (95% CI: -0.3, -0.0) between baseline and FU2. Dinner intake decreased by -0.1 days per week (95% CI: -0.2, -0.0) between baseline and both FU1 and FU2. Only minor differences in risk substance use were observed. Similar changes were observed in analyses stratified by age and sex.

Conclusions

Lifestyle behaviors in Swedish university students slightly improved during the first six months of the COVID-19 pandemic compared to before.

Alcohol Use and Gambling Associated with Impulsivity among a Swedish University Sample

Excessive alcohol use and gambling can have negative consequences. Across countries, the risk of excessive alcohol use is more common in university populations than in the general population. However, few studies have investigated the prevalence of both alcohol use and gambling in this group. This study explores these behaviours in a Swedish university setting. In addition, this study investigates how impulsivity affects alcohol use and gambling. In total, 794 Swedish students answered an online survey. Data were analysed using descriptive statistics to determine prevalence, and multinomial logistic regression was used to determine the contribution of impulsivity, age, and sex to alcohol use and gambling. Compared to the Swedish national prevalence, the prevalence was higher for excessive alcohol use, but the prevalence of gambling was at the same level or lower. High levels of impulsivity and male sex increased the risk of excessive alcohol use, while older age lowered the risk of excessive alcohol use and gambling. The results indicate that primarily young men could benefit from primary prevention in a university setting. Also, screening for impulsivity in men might be one way to identify risk groups in a university population.

The morning after the night before: Alcohol-induced blackouts impair next day recall in sober young adults

Binge-drinking in adolescents and young adults is a widespread problem, however, an often unreported consequence of binge-drinking behaviour is an alcohol-induced memory blackout (MBO). An MBO is a transient amnesic event resulting from rapid, excessive alcohol consumption. Here, we examine the short-term impact of an alcohol-induced MBO event (testing < 20 hours after blackout) on memory performance in people who have experienced a high volume of MBOs. In addition, we aimed to test the hypothesis that people who experience a high volume of MBOs may have poorer recall than non-blackout controls in either sober or intoxicated states. Three episodic memory paradigms consisting of free recall, serial recall, and depth of encoding tasks, were conducted by a group of alcohol drinkers who had never experienced a memory blackout, and those who reported at least 9 in the preceding 12-months. Studies were completed sober and after alcohol by all participants, and sober but after blackout by the experimental group. Accuracy of recall was assessed with linear mixed effects modelling for all experiments and conditions. Recall rate both before and after alcohol consumption was similar between groups, with poorer recall after drinking alcohol by all participants in all three studies. After blackout, MBO participants showed no significant improvement from their intoxicated state in serial recall and depth of encoding tasks, but an improvement in free recall. Further analysis of these findings revealed that 10 out of 23 participants showed significantly impaired performance after blackout during free recall, extending up to 17 participants in serial recall. In general, alcohol reduced recall rate in both blackout and control participants similarly, but recall following MBO remained poor. Our evidence suggests that alcohol-induced blackouts impair memory functioning the next day, and future research should establish the duration of deficits after an acute alcohol-induced blackout episode.

A Proposal for a Taxonomy of Pre-Loading

Background: Pre-loading of alcohol and other drugs has become a prevalent start to nights out in many countries. Studies into pre-loading have been using different operational definitions and descriptions, leading to confusion and debate in the research literature. Purpose/Objective: We wish to propose a full taxonomy so that research into preloading, of any substances, can be specific and standardized. Methods: We address this problem by analyzing (1) terminology used throughout the literature, (2) the evolving nature of this phenomenon, and (3) the operational components comprising this substance use practice. Additionally, we provide a context and rationale for how we view pre-loading in relation to the broader event-level session. Results: Our results propose a full operational definition and taxonomy of pre-loading to be used, and built upon, by researchers. We also provide a visual representation of pre-loading within an event-level session and provide a method to facilitate consistency across cultures. Conclusions: We propose that this system will lead to greater specificity and higher reliability in the interpretation of research results.
