Tobacco use, cirrhosis, and age are predictors of readiness to change and continued drinking following brief alcohol intervention in Veterans.

Alcohol-use disorder (AUD) is prevalent within the Veterans Health System, especially in patients being seen in hepatology clinics, and needs a point-of-care strategy. A brief alcohol intervention based on AUDIT-C (Alcohol Use Disorders Identification Test) may be needed for management of hazardous alcohol intake, but feasibility is unclear. We aimed to define predictors of readiness to cease alcohol intake (0-10, 10 being ready to quit now) and continued drinking after using a brief alcohol intervention in Veterans seen in hepatology clinics cross-sectionally and longitudinally over 6 months. A total of 414 men with liver disease (average age of 61 years old, 48% with cirrhosis, 31% with concomitant psychiatric conditions, 44% with tobacco use, 14% with prior AUD therapy) were approached. 144 patients (35%) had a positive AUDIT-C (8.9±4.0) and were given the brief intervention. 80 of these patients (56%) had a high readiness to change, listing "wanting to improve health" and "prior success at reducing alcohol intake" as their most frequent reasoning. On regression analysis, concomitant tobacco use was associated with a significantly lower readiness to quit alcohol score. On longitudinal follow-up at 6 months, 34 (23%) patients were still drinking. These patients were older, and more likely to have concomitant diagnoses of cirrhosis and anxiety. Overall, we found that in a large cohort of Veterans seen in hepatology clinics that in routine practice,a brief intervention targeted at alcohol use is feasible. Older patients with concomitant tobacco use, cirrhosis, and anxiety may need more longitudinal attention to ensure that the initial interest in reducing problem drinking is sustained.

Alcohol and cannabis use associated with cardiometabolic biomarkers among "All of Us" cancer survivors.

Cancer survivors are at increased risk for cardiometabolic comorbidities following cancer treatment which may be further exacerbated by cannabis and alcohol use. We aimed to examine the direct relationships of cannabis, alcohol, and the co-use of both substances with cardiometabolic risk factors and to explore disparities by race/ethnicity and sex. Cross-sectional data were extracted from adult cancer survivors in the "All of Us" from 2018-2022. Cannabis use was defined as occasional or frequent/regular cannabis use (vs never) in the past three months and hazardous alcohol intake (AUDIT-C >3 for females, AUDIT-C >4 for males) vs non-hazardous in the past year, respectively. Co-use was defined as participants who engaged in regular cannabis and hazardous alcohol intake. We identified binary cardiovascular, immune, and metabolic systems biomarkers, with high values defined by clinically established cutoffs or >75th percentile. We used multivariable logistic regression adjusting for socio-demographic and clinical factors. In our sample (N=7,054), 7.6% were Hispanic, 6.2% were Black, and 86.2% were White cancer survivors. Less than 5% of Hispanic and White survivors reported substance co-use compared to 7% of Black survivors. Compared to never users, co-users were 1.58(95% CI=1.14-2.19) more likely to have high blood pressure. No significant associations were found between co-use and immune biomarkers or sex differences. Co-use of cannabis and hazardous alcohol may worsen high blood pressure in survivors, who are at higher risk for cardiometabolic comorbidities. The study investigates substance use and cardiometabolic biomarkers, urging more research on their effects on cancer survivors.

Hazardous alcohol consumption is associated with an increased occurrence of falls among people with HIV in the PROSPER-HIV Study.

Falls are a significant public health concern, particularly among older adults and people with HIV (PWH). This study examines the association between alcohol consumption and falls in PWH. The PROSPER-HIV study recruited PWH from four US sites. Participants were categorized based on Alcohol Use Disorders Identification Test Consumption (AUDIT-C) scores: none, non-hazardous, and hazardous drinking. Data collection included demographics, medical history (i.e., comorbidities, treated hypertension, eGFR), alcohol consumption using AUDIT-C, daily alcohol recall in grams, and self-reported falls over the previous year. Physical performance was measured using the Short Performance Physical Battery (SPPB). Statistical analyses included Pearson's correlation and Poisson regression models to estimate fall prevalence ratios (PR), adjusting for confounders (SPPB, comorbidities, treated hypertension, and eGFR). The study included 315 PWH, aged 52 ± 12 years, with 78% male participants. Thirty-three percent were classified as non-drinking, 50% non-hazardous, and 17% hazardous drinking. Poisson regression showed a significantly higher risk of falls (PR: 2.12, 95% CI: 1.11-4.03) and recurrent falls (PR: 3.54, 95% CI: 1.21-10.3) among hazardous drinking compared to non-hazardous drinking, even after adjusting for confounders. The PR for falls per daily intake in grams was not statistically significant. There is a significant association between hazardous alcohol consumption and increased fall risk in PWH using AUDIT-C, but not when accessing recall of alcohol consumption in grams.

Associations between employees' alcohol consumption, insomnia and HR management strength.

Understanding of hazardous alcohol drinking and insomnia among Australian ambulance personnel is limited. Australian ambulance organizations have strengthened their organizational human resource management (HRM) to promote their employees' healthy lifestyles, health and well-being. To describe the prevalence of hazardous alcohol consumption and insomnia among Australian ambulance personnel and to explore their associations with the organizational HRM strength. This cross-sectional study was conducted on 492 ambulance personnel randomly selected from three Australian states. The Alcohol Use Disorders tool, The Insomnia Severity Index and the Perceived HRM System Strength instrument measured alcohol consumption, insomnia and HRM strength. Descriptive analyses, bivariate association analyses and general linear models were used for data analysis. Twenty per cent of Australian ambulance personnel consumed alcohol at a hazardous level and 68% experienced clinically significant insomnia. There was no significant association between organizational HRM strength and ambulance personnel's hazardous alcohol consumption. There was a significant association between organizational HRM strength (consensus) and ambulance personnel's insomnia experience. Hazardous alcohol consumption and insomnia were concerns among Australian ambulance personnel. Even though strengthening the HRM system might reduce their experience of insomnia, simply strengthening the HRM system could not reduce their hazardous alcohol consumption.

Sexual Violence and Hazardous Drinking: Exploring Associations With PTSD Symptoms and Gender Among Adults With Probable PTSD and Hazardous Drinking.

Sexual violence is associated with posttraumatic stress disorder (PTSD), but relatively less research has explored whether it is associated with hazardous drinking. PTSD symptoms may indirectly influence the association between sexual violence and hazardous alcohol use. This association may be moderated by gender. The aim of the current study was to cross-sectionally test whether sexual violence is indirectly associated with hazardous drinking through PTSD symptoms and explore whether gender moderates this association. Hypotheses were tested among 631 adults (Mage = 38, 56% men, 78.6% White) with probable PTSD and hazardous drinking who completed online self-report surveys. Results indicated sexual violence, compared with other trauma types, was associated with more severe hazardous drinking. There was a significant indirect effect of PTSD symptoms in this association. There was no evidence of a moderating effect of gender. PTSD symptoms may drive hazardous drinking among sexual violence survivors. Results also underscore associations between sexual violence and alcohol use, regardless of gender. Future work should continue to investigate these associations prospectively.

Impulsivity Moderates the Association Between Hazardous Alcohol Use and Risky Sexual Behaviors Among Cisgender Bisexual Women

Bisexual women report higher rates of alcohol use and risky sexual behavior than lesbian and heterosexual women. Impulsivity (i.e., action without considering negative consequences) is a risk factor for greater alcohol use and sexual behavior, but few studies have examined the impact of impulsivity on alcohol use and sexual behavior among cisgender bisexual women. Consequently, the purpose of this study was to examine the moderating role of impulsivity on the association between hazardous alcohol use and sexual risk-taking among cisgender bisexual emerging adults. Participants were 225 self-identified cisgender bisexual women (Ma ge = 22.77, SD = 3.45) who completed an online survey about their hazardous alcohol use using the Alcohol Use Disorder Identification Test (AUDIT), impulsivity, and sexual behaviors over the past 30 days. A moderated regression model examined main effects of impulsivity and alcohol use severity, and their interaction, on sexual risk-taking. The association between alcohol use severity and sexual risk-taking was moderated by impulsivity. Simple slopes analyses revealed that greater alcohol use severity was associated with greater sexual risk-taking, but this only occurred for participants with average or high scores of impulsivity. These results suggest prevention programs that target alcohol use should address the role that impulsivity may have on risky sexual behaviors among young bisexual women. Future research would benefit from looking at various outcomes related to sexual risk to determine which are most predominantly associated with alcohol use severity and impulsivity.

Mental Health and Substance Use Among Black Women Attending STD Clinics in Baltimore: The Role of Overt and Subtle Discrimination.

Black women are disproportionately impacted by mental health conditions, like depression, posttraumatic stress disorder (PTSD), and substance use harms. Experiences of discrimination may cause and exacerbate these conditions, but little is known about how distinct types of discrimination (overt vs. subtle) may be related to these outcomes. The current study sought to evaluate the associations between overt and subtle discrimination, mental health, and substance misuse outcomes among Black women. Data were drawn from ESSENCE, a retrospective cohort study (2013-2018) on sexual assault and HIV risk among Black women attending sexually transmitted disease (STD) clinics in Baltimore, Maryland (n = 199). Multivariable Poisson regression models tested the associations between overt and subtle discrimination, depressive and PTSD symptoms, and substance misuse while controlling for covariates. Nearly half (42.2%) of participants reported depressive symptoms, and over a third reported severe PTSD symptoms (35.2%). Higher levels of subtle discrimination were associated with increased risk of depressive symptoms (adjusted relative risk [aRR] = 1.32, 95% confidence interval [CI]: 1.16, 1.50, p < .0001), whereas higher levels of overt discrimination were associated with increased risk of severe PTSD symptoms (aRR = 1.22, 95% CI [1.02, 1.46], p = .0287). Neither overt nor subtle discrimination was significantly associated with hazardous alcohol use or daily marijuana use in adjusted models. We identified that subtle discrimination has a unique negative association with depressive symptoms, while overt discrimination is positively associated with PTSD symptoms. This information is critical for tailoring stigma reduction interventions and mental health supports for Black women.

Syndemic Conditions Associated with Hazardous Alcohol Consumption among Sexual Minority Men in San Francisco

BackgroundHazardous alcohol consumption (HAC) is prevalent among sexual minority men (SMM). Using syndemic theory, this study aimed to identify the number of syndemic conditions, including their combinations, and their association with HAC among SMM in San Francisco. MethodWe conducted a secondary analysis of cross-sectional data from 246 SMM who consume alcohol. Syndemic factors included multiple substance use, depressive symptoms, HIV/STI status, and houselessness. We conducted a multivariable logistic regression to estimate the odds of HAC associated with increasing syndemic conditions. We further examined which combinations of three syndemic factors were associated with the highest odds for HAC. ResultsThe average age was 40.7; participants were predominantly White (33.3%) and Black/African American (29.7%) and graduated from high school (92.7%). The prevalence of HAC increased with the number of syndemic conditions: 13.6% with none, 30.9% with one, 51.9% with two, 65.1% with three, and 69.2% with four conditions. A significant log-linear trend was observed, with two syndemic conditions increasing the odds of HAC over fivefold (AOR=5.05, 95% CI=1.68–15.15), and three and four syndemic conditions increasing the odds by more than eightfold (AOR=8.82, 95% CI=2.74–28.39; AOR=8.55, 95% CI=2.26–32.28). The combination of depressive symptoms, HIV/STI status, and houselessness tripled the odds for HAC (OR=3.07, 95% CI=1.34–7.04). ConclusionHAC was associated with increasing syndemics, and specific conditions (depression, HIV/STI, and houselessness) had the greatest odds of HAC. These findings underscore the need for comprehensive screening and integrated interventions targeting these co-occurring conditions to reduce HAC in this population.

Interest in the Use of Herbal Supplements to Close the Treatment Gap for Hazardous Alcohol Use Among Men Who Have Sex With Men: Secondary Analysis of a Cross-Sectional Study.

Hazardous alcohol consumption is highly prevalent for men who have sex with men (MSM). The 4 treatments currently approved by the Food and Drug Administration for alcohol use are reaching an alarmingly low percentage of people who would benefit from a reduction in their alcohol use. There is increasing interest in alternative methods of treatment, such as herbal supplements, to address hazardous drinking. However, research on the acceptability of alternative pharmacotherapies among MSM remains limited. We examined the prevalence and correlates of expressing interest in using herbal supplements for alcohol treatment among MSM with hazardous alcohol consumption. We conducted a secondary data analysis from a cross-sectional study of MSM who use alcohol, conducted from March 2015 to July 2017 in San Francisco, California, to assess the overall prevalence of interest in using herbal supplements to help reduce alcohol consumption. Associations between expressing interest in herbal supplements and demographic, social, and clinical characteristics were examined using bivariate and multivariable logistic regression models. One-third (66/200, 33%) of the participants expressed interest in an herbal supplement for reducing alcohol consumption. In the multivariable analyses, weekly binge drinking (adjusted odds ratio [aOR] 2.85, 95% CI 1.17-6.93), interest in abstaining from alcohol use (aOR 5.04, 95% CI 1.46-17.40), higher severity of alcohol dependence score (aOR 1.22, 95% CI 1.04-1.41), and interest in naltrexone (aOR 3.22, 95% CI 2.12-4.91) were independently associated with higher odds of being interested in using an herbal supplement to reduce alcohol consumption, adjusting for age, race or ethnicity, and education. We found that MSM who have hazardous drinking habits, more severe alcohol dependence, and interest in pharmacotherapy were more likely to express interest in using an herbal supplement for reducing alcohol consumption. To our knowledge, this is the first study that has evaluated correlates of interest in herbal supplements for alcohol use among MSM. As researchers implement novel alcohol treatment studies, they should focus on recruitment efforts among MSM with a motivation to reduce their alcohol use patterns.

Alcohol Misuse and Correlates with Mental Health Indicators among Firefighters

Background: Stress and repetitive exposures to potentially traumatizing events are inherent to first-responder professions. Firefighters and other crisis responders are often exposed to incidents in their work environments and are at risk of developing acute or posttraumatic symptomatology, depression, and anxiety, as well as harmful patterns of alcohol consumption. Most prior research and theory suggests that many firefighters use alcohol to cope with past and current stressors, and that increased drinking accompanies ongoing exposures to stressful occupational hazards. Objectives: The primary aim of this research was to examine alcohol consumption and mental health variables associated in the literature with alcohol misuse. Participants included 546 predominantly male career firefighters in the U.S. Using a cross-sectional design, we examined alcohol misuse in the context of self-reported depression, generalized anxiety, PTSD, and suicidal ideation using previously validated measures. Results: Based on the AUDIT’s recommended cut score of 8, 38.8% of our sample reported drinking at hazardous levels. Hazardous alcohol use was also significantly associated with several mental health indicators with correlations ranging from .28 to .34. Regression analyses revealed that over 14% of the variance in AUDIT scores could be explained by psychological symptom measures, and 29% of the variance in suicide risk was explained by a model using both alcohol and mental health measures. Conclusions: Findings suggest that psychological distress is associated with hazardous drinking, and that more consistent screening and referral for these issues, as well as multi-level interventions, are needed to effectively address these behavioral health concerns among firefighters.

Work- &amp; family-related stress &amp; the risk of hazardous alcohol use: role of sex and social support

Abstract Background There is a lack of longitudinal studies investigating the effect of individual stress factors on alcohol use behaviour, and how sex and social support may mitigate the effect of these stressors. We aimed to determine the association of work- and family-related stressors with developing hazardous alcohol use over time among habitual drinkers, and to examine the role of sex and social support in these associations. Methods A sample of 4,046 individuals, working and living in Stockholm, age 25-55 years, habitual drinkers, who answered the PART study (Swedish acronym for Mental Health, Work and Social Relations) questionnaire regarding work- and family-related stress (exposures) in 1998-2000 (wave1) and 2001-2003 (wave2) were followed until 2010 (wave3) regarding hazardous alcohol use (outcome) measured using Alcohol-Use-Disorder-Identification-Test (AUDIT) score ( &amp;gt; =8 in men, &amp;gt; =7 in women). Weights for selective attrition were calculated, and crude and multivariate (adjusting for sociodemographic, health- and previous stress-related factors) logistic regression models, yielding Odds Ratios (OR) with 95% Confidence Intervals (CI), were used to estimate the exposure-outcome associations. Analyses were stratified for sex and social support in general and at work. Results Job strain (a combination of high demand and low control) was not statistically significantly associated with hazardous alcohol use (OR, CI: 1.3, 0.9-1.9). Among those reporting any family-related stress, a significantly higher risk was observed (OR, CI: 1.5, 1.1-2.1), particularly among women (OR, CI: 1.7, 1.02-2.7) and those with low social support (OR, CI: 2.1, 1.2-3.6). These associations became non-significant after adjusting for previous family-related stress. Conclusions Public health measures aiming to prevent transitions from habitual to hazardous alcohol use should give special attention to individuals with family-related stress, especially among women and those with low social support. Key messages • While job stress was not significantly associated, those experiencing family-related stress had a higher risk of hazardous alcohol use, especially among women and those without social support. • Individuals experiencing family-related stress, particularly women and those lacking social support, require special attention in public health prevention strategies for risky alcohol consumption.

Examining the link between age of alcohol initiation, adolescent alcohol use and adult substance use

Abstract Background Understanding the relationship between adolescent alcohol use and adult substance use is important for prevention programmes. Existing evidence presents divergent findings and potential mechanisms are debated. Methods We estimated associations between the age of alcohol initiation and alcohol use at age 17 and substance use at age 20 in a nationally representative cohort (n = 4554). Weighted logistic regression models were fitted using Generalised Estimating Equations in multiply imputed and complete case data. Results Our analysis identified that 27% of participants reported first alcohol use at ≤ 14 years old, with 37% engaging in risky alcohol use by age 17. At age 20, 14% reported hazardous alcohol use, while 38% used tobacco, 24% cannabis, and 28% other drugs. The age at which alcohol was initiated and risky alcohol use at 17 years old were both strongly associated with alcohol, tobacco, cannabis and other illicit drug use at 20 years old. Sequential change in effect estimates coupled with non-overlapping confidence intervals suggest a dose-response relationship between age of alcohol initiation and tobacco and other drug use at age 20. Conclusions First use of alcohol at 14 or younger was common. Earlier alcohol initiation and risky alcohol use are each associated with substantially elevated risk for substance use at 20 years old even after accounting for common liability factors. Acknowledgement: Growing Up in Ireland (GUI) is funded by the Department of Children, Equality, Disability, Integration and Youth (DCEDIY).

Neither the CSO nor DCEDIY take any responsibility for the views expressed or the outputs generated from these analyses. Key messages • Delaying alcohol initiation and preventing risky alcohol use during adolescence may reduce levels of substance use in young adults. • Self-reported early use of alcohol remains common.

Characterizing long-acting injectable antiretroviral therapy eligibility and initiation at a safety net academic medical center in the southeastern United States.

Background: Long-acting injectable (LAI) cabotegravir/rilpivirine (CAB/RPV) extends dosing intervals from daily to every 8weeks. Equitable implementation requires anticipating and addressing barriers to use. We described LAI-CAB/RPV eligibility and initiation among persons with HIV (PWH) receiving care at a Southeastern US academic medical center. Methods: We included PWH ≥18years, in care 01/01/2020-12/31/2021, and participating in the UNC CFAR HIV Clinical Cohort. We characterized LAI-CAB/RPV eligibility, compared those with and without recent detectable viral load (VL), and described clinical outcomes on LAI-CAB/RPV. Results: Among 1672 PWH, 425 (25.4%) had LAI-CAB/RPV drug-resistance. Among 1238 LAI-eligible PWH, 8.9% had detectable VL. Median age was 53 (interquartile range 40, 61), 54.6% were non-Hispanic Black, and 73.6% male. Over one-third lived >50 miles from clinic, one-fifth were uninsured, and 7.4% reported hazardous alcohol use. Gaps in care (prior 12-month) were more common among PWH with detectable VL versus suppressed (23.1% vs 13.9%, p = 0.03). 6/47 initiated LAI-CAB/RPV had detectable VL prior to injection; >95% sustained suppression and those with detectable VL had a rapid decline in viremia. Conclusions: Three-quarters of PWH were eligible for LAI-CAB/RPV, but equitable implementation may require addressing challenges such as distance to care, inconsistent care engagement, and other comorbid conditions, particularly for PWH with viremia.

The relationship between co-occurring traumatic experiences and co-occurring mental health domains for veterans resident in Northern Ireland

IntroductionVeterans residing in Northern Ireland (NI) likely experience higher levels of co-occurring lifetime trauma exposure and associated co-occurring mental health symptoms, due to the Troubles. As NI veterans have been subject to little exploration it is difficult to know how to support them. This exploratory study explored the co-occurrence of mental health symptoms as a function of co-occurring traumatic experiences.MethodsTwo latent class analyses (LCA) were conducted on NI veteran data (n = 609). One LCA factored endorsements of 16-lifetime traumatic events, with a separate LCA exploring the co-occurrence of symptoms across six mental health domains. Mental health symptom classes were considered as a function of trauma classes, military-specific variables, gender and age.ResultsThree trauma classes were identified: High Multi Trauma (10.84%); High Combat/Conflict (47.62%); Moderate Combat Conflict (41.54%), and three mental health symptom classes: High Co-occurring Mental Health (19.38%); High Depression Moderate Anxiety/Alcohol (24.63%); Moderate Alcohol/Normative (55.99%). Significant predictors of High Co-occurring Mental Health class membership were UDR service, ‘Worst’ military trauma and High Multi Trauma class membership. Both combat classes had a negative relationship with the High Co-occurring Mental Health. Predictors of the High Depression Moderate Anxiety/Alcohol class were High Multi Trauma class membership and UDR service, with Age and Moderate Combat Class membership having a negative relationship.DiscussionNI veterans could be labelled as ‘traumatised’ due to high levels of combat/conflict exposure, yet the two combat classes seemed unrelated to membership of poorer mental health classes. UDR membership indicated that living in one’s theatre of war could have mental health implications. It was concerning that 45% experienced some co-occurring mental health symptoms with 19% experiencing the poorest symptoms. Hazardous alcohol use appeared unrelated to poor mental health. Further research is needed, utilising robust methods. No clinical inferences are to be made from this exploratory study.

Addressing India’s alcohol misuse crisis: The urgent need for screening and brief intervention to bridge the healthcare gap

India faces a significant challenge with alcohol misuse, as evidenced by the national survey revealing that 57 million out of 160 million persons with alcohol use exhibit harmful or dependent patterns, necessitating professional assistance. The Global Status Report on Alcohol and Health (2018) indicates a rising per capita alcohol consumption in the Southeast Asian Region, with India contributing substantially. To address this, implementing policies and programs to curb hazardous alcohol use is crucial. Despite a shortage of mental health professionals in India, they remain the primary caregivers for those with alcohol-related issues. Only one in five individuals with problematic alcohol use can access professional help. I argue for adopting Screening and Brief Intervention (SBI) to bridge this healthcare gap. SBI is a concise, structured counseling approach that proves effective and scalable. It can be delivered by various healthcare providers, including doctors, nurses, counselors, and paramedics. Hence, it can be seamlessly integrated into primary care, emergency, and nonclinical settings. The efficacy of SBI extends to electronic formats, providing a scope of expansion through telehealth. The WHO advocates SBI by its SAFER initiative aimed at reducing negative alcohol-associated health and social consequences. SBI is effective across age groups, including adolescents and young adults, constituting most of India’s population. Emerging evidence suggests that SBI is acceptable, feasible, and effective in the Indian context. Universal or targeted SBI can be a pivotal tool in achieving the Sustainable Development Goals (2030) and global commitments for noncommunicable diseases, fortifying efforts to prevent and treat alcohol misuse.

Serum BDNF and pro-BDNF levels in alcohol use disorders according to depression status: An exploratory study of their evolution two months after withdrawal

BackgroundAlcohol use disorders (AUDs) are complex pathologies with a myriad of molecular actors involved in both disease progression and remission. Brain-derived neurotrophic factor (BDNF) is suspected to be one such actor due to its neurotrophic effects. The BDNF precursor, pro-BDNF, has different effects, as it mainly promotes neuronal apoptosis. Both forms also play a role in depression and depressive episodes (DE). The aim of this exploratory study was to compare serum BDNF and pro-BDNF levels in patients with AUDs after withdrawal and according to DE status with those of controls without AUDs or DE. Materials and methodsNinety-nine AUD patients and 40 controls were included. Questionnaires were used to assess both alcohol and psychiatric domains: the severity of hazardous alcohol consumption was assessed using Alcohol Use Disorders Identification Test (AUDIT), craving was assessed using Obsessive and Compulsive Drinking Scale (OCDS), anxiety was assessed with Hamilton Anxiety Rating Scale (HAM-A) and depression with Montgomery-Åsberg Depression Rating Scale (MADRS). Blood samples were collected during two visits: at the time of alcohol withdrawal (M0) and two months later (M2). ELISAs to measure serum BDNF and pro-BDNF levels were performed. AUD patients were categorized according to depression status at M2. Forty-five patients remained abstinent whereas 54 relapsed. BDNF serum levels rose after alcohol withdrawal, but pro-BDNF levels did not vary between M0 and M2. ResultsAUD subjects without DE at M2 had higher BDNF levels at both M0 and M2 than AUD subjects with DE at M2. AUD subjects showed lower MADRS and OCD scores at M2 than at M0. AUD subjects without DE had lower BDNF levels at M0 than controls but not at M2, regardless of abstinence maintenance. ConclusionBDNF serum levels were reduced in AUD patients compared to controls and were further reduced in patients with both AUDs and DE. Alcohol withdrawal treatment was sufficient to induce an increase in serum BDNF levels after 2 months, regardless of whether abstinence was maintained during this time period.

A randomized controlled trial testing the efficacy of the eCHECKUP TO GO on drinking games participation and behavior among high school seniors

BackgroundAmong high school students, seniors report the highest levels of hazardous drinking behavior, including playing drinking games. Technology-based interventions are a promising approach for reducing hazardous drinking behavior among this age group. Objectives: This randomized controlled trial investigated the efficacy of the eCHECKUP TO GO, an online personalized feedback intervention, on reducing the frequency of playing drinking games, the number of drinks consumed while playing drinking games, and the number of drinks consumed on occasions when drinking games were played among high school seniors (ClinicalTrials.gov Identifier NCT03613818). Method: Participants were recruited from two high schools. Class periods were randomized to the intervention condition or an assessment-only control condition. Participants completed online surveys at baseline, 30-day, and 6-month assessments. The subsample in this study (N = 109) consisted of high-risk drinkers (i.e., students reporting binge drinking in the past two weeks at baseline). Results: We did not find any significant differences in frequency of playing drinking games between the intervention and control conditions. For number of drinks consumed, students in the intervention condition reported a significant reduction in the number of drinks consumed while playing drinking games (p < 0.01) and total number of drinks consumed on drinking game occasions (p < 0.04) at the 30-day follow-up relative to students in the control condition. Reductions within the intervention group were sustained at the 6-month follow-up. Conclusions: Results support the efficacy of the eCHECKUP TO GO for decreasing hazardous alcohol use among high school seniors.

Containment Measures and Alcohol Consumption Among Drinking Higher Education Students Before and During the COVID-19 Pandemic: A Multilevel Analysis in 25 Countries.

Hazardous alcohol use tends to be more prominent among higher education students. The COVID-19 pandemic severely altered student life, raising questions on its impact on students' alcohol use patterns. The current study examined cross-country variations in drinking behaviors (weekly drinking and binge drinking), and the extent to which these variations were associated with containment measures implemented during the first wave of the COVID-19 pandemic. Data were obtained from the COVID-19 International Student Well-being Study, covering students in 25 middle- and upper-high income countries. Data on government responses were retrieved from the Oxford COVID-19 Government Response Tracker. Multilevel multinomial logistic regression analyses were performed on weekly drinking (n = 44,212) and binge drinking (n = 32,785). Considerable cross-country variation existed for weekly drinking and binge drinking. In the majority of countries, a self-reported decrease in weekly drinking and a substantial self-reported decrease in binge drinking were observed. Closings of schools were associated with decreases in weekly drinking, while limitations on social gatherings were associated with increases in weekly drinking. The stringency index was associated with reporting decreased binge drinking. The study findings demonstrate a number of small yet significant associations between containment measures and changes in student drinking behaviors. Future studies are required to uncover why some students increased their alcohol consumption, particularly in countries with stricter limitations on social gatherings.
