ABSTRACT
BACKGROUND: Alcohol consumption is associated with cardiovascular disease, and the sympathetic nervous system is a suspected mediator. The present study investigated sympathetic transduction of muscle sympathetic nerve activity to blood pressure at rest and in response to cold pressor test following evening binge alcohol or fluid control, with the hypothesis that sympathetic transduction would be elevated the morning after binge alcohol consumption. METHODS: Using a randomized, fluid-controlled (FC) crossover design, 26 healthy adults (12 male, 14 female, 25±6 years, 27±4 kg/m2) received an evening binge alcohol dose and a FC. All participants underwent next-morning autonomic-cardiovascular testing consisting of muscle sympathetic nerve activity, beat-to-beat blood pressure, and heart rate during a 10-minute rest period and a 2-minute cold pressor test. Sympathetic transduction was assessed at rest and during the cold pressor test in both experimental conditions. RESULTS: Evening alcohol increased heart rate (FC: 60±9 versus alcohol: 64±9 bpm; P=0.010) but did not alter resting mean arterial pressure (FC: 80±6 versus alcohol: 80±7 mmâ Hg; P=0.857) or muscle sympathetic nerve activity (FC: 18±9 versus alcohol: 20±8 bursts/min; P=0.283). Sympathetic transduction to mean arterial pressure (time×condition; P=0.003), diastolic blood pressure (time×condition; P=0.010), and total vascular conductance (time×condition; P=0.004) was augmented after alcohol at rest. Sympathetic transduction during the cold pressor test was also elevated after evening binge alcohol consumption (P=0.002). CONCLUSIONS: These findings suggest that evening binge alcohol consumption leads to augmented morning-after sympathetic transduction of muscle sympathetic nerve activity to blood pressure, highlighting a new mechanism whereby chronic or excessive alcohol consumption contributes to cardiovascular disease progression via altered end-organ responsiveness to sympathetic neural outflow.

ABSTRACT
INTRODUCTION: While the negative effects of drunk driving, including road traffic injuries (RTIs) have been well documented in high-income countries, little has been reported in African countries like Cameroon. This study aimed to measure the prevalence of alcohol-related RTIs (ARRTIs), its associated factors, and its association with injury severity. METHODS: The Cameroon Trauma Registry prospectively collects trauma data from 10 hospitals in Cameroon. This study included patients enrolled between June 2022 and May 2023 for acute RTIs. We assessed the frequency of binge drinking episodes in the past year and self-reported alcohol consumption 6 h before RTI. Bivariate analysis using chi-squared or Fisher's exact test was used to test for associations between ARRTIs and independent variables. Multivariate logistic regression was performed with variables with a P value < 0.05. RESULTS: A total of 3761 RTI cases were recorded with 77.5% (n = 2909) males and a median age of 32 y (IQR = 20 y). Prevalence of ARRTI was 9.01% (n = 338). Any self-reported binge drinking episodes (less than monthly adjusted odds ratio [AOR] = 4.97, 95% confidence interval [CI] = 3.39-7.25; monthly AOR = 5.47, 95% CI = 3.66-8.11; weekly AOR = 6.55, 95% CI = 4.63-9.27; or daily AOR = 11.15, 95% CI = 7.52-16.52) was significantly associated with ARRTI compared to none reported. Male gender, higher educational status, tobacco use, depression, and means of transportation were other associated factors. CONCLUSIONS: Almost one in 10 patients had consumed alcohol 6 h prior to RTI with odds of ARRTI significantly increasing with increased frequency in binge drinking. There is a need for evidenced-based, integrated approaches targeting sociodemographic and behavioral factors toward prevention of ARRTIs in Cameroon.
ABSTRACT
Early adolescent drinking onset is linked to myriad negative consequences. Using the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA) baseline to year 8 data, this study (1) leveraged best subsets selection and Cox Proportional Hazards regressions to identify the most robust predictors of adolescent first and regular drinking onset, and (2) examined the clinical utility of drinking onset in forecasting later binge drinking and withdrawal effects. Baseline predictors included youth psychodevelopmental characteristics, cognition, brain structure, family, peer, and neighborhood domains. Participants (N=538) were alcohol-naïve at baseline. The strongest predictors of first and regular drinking onset were positive alcohol expectancies (Hazard Ratios [HRs]=1.67-1.87), easy home alcohol access (HRs=1.62-1.67), more parental solicitation (e.g., inquiring about activities; HRs=1.72-1.76), and less parental control and knowledge (HRs=.72-.73). Robust linear regressions showed earlier first and regular drinking onset predicted earlier transition into binge and regular binge drinking (ßs=0.57-0.95). Zero-inflated Poisson regressions revealed that delayed first and regular drinking increased the likelihood (Incidence Rate Ratios [IRR]=1.62 and IRR=1.29, respectively) of never experiencing withdrawal. Findings identified behavioral and environmental factors predicting temporal paths to youthful drinking, dissociated first from regular drinking initiation, and revealed adverse sequelae of younger drinking initiation, supporting efforts to delay drinking onset.
ABSTRACT
BACKGROUND: Information on trajectories of diffuse subcortical brain damage of vascular origin associated with binge drinking in older adults is limited. We sought to evaluate the impact of this drinking pattern on the progression of white matter hyperintensities (WMH) of presumed vascular origin in individuals aged ≥60 years taken from the community. METHODS: Following a longitudinal prospective design, participants of the Atahualpa Project Cohort received interviews to assess patterns of alcohol intake as well as baseline and follow-up brain MRIs. Only men were included because alcohol consumption in women is negligible and tend not to engage in binge drinking in our studied population. Poisson regression models were fitted to assess the incidence rate ratio of WMH progression by patterns of alcohol use (binge drinking or not), after adjusting for demographics, level of education and cardiovascular risk factors. RESULTS: The study included 114 men aged ≥60 years (mean age: 65.1±5.4 years). Thirty-seven participants (32%) reported binge drinking for more than 30 years. Follow-up MRIs revealed WMH progression in 45 participants (39%) after a median of 7.2 years. In unadjusted analysis, the risk of WMH progression among individuals with binge drinking was 2.08 (95% C.I.: 1.16-3.73). After adjustment for age, education level and vascular risk factors, participants with this drinking pattern were 2.75 times (95% C.I.: 1.42-5.30) more likely to have WMH progression than those who did not. CONCLUSIONS: Study results show an independent association between binge drinking and WMH progression in community-dwelling older men.
ABSTRACT
Linalool-rich Rosewood oil (Aniba rosaeodora Ducke) is a natural compound widely used in perfumery industry. Evidence suggests that linalool exerts antidepressant and anxiolytic effects. Conversely, ethanol binge drinking (i.e., intermittent and episodic consumption) during adolescence elicits neurobehavioral alterations associated with brain damage. Here, we investigated whether linalool-rich Rosewood oil administration can improve the emotional and molecular impairments associated with ethanol binge-like exposure during adolescence in female rats. Rosewood oil was obtained by hydrodistillation and posteriorly analyzed. Adolescent female Wistar rats received four-cycles of ethanol binge-like pattern (3â¯g/kg/day, 3 days on/4 days off) and daily Rosewood oil (35â¯mg/kg, intranasally) for 28 days. Twenty-four hours after treatments, it was evaluated the impact of ethanol exposure and Rosewood oil treatment on the putative emotional impairments assessed on the splash and forced swimming tests, as well as the levels of brain-derived neurotrophic factor (BDNF), S100B, oxidative parameters, and inflammatory cytokines in prefrontal cortex and hippocampus. Results indicated that Rosewood oil intranasal administration mitigated emotional impairments induced by ethanol exposure accompanied by a marked increase in BDNF, S100B, glutathione (GSH), and antioxidant activity equivalent to Trolox (TEAC) levels in brain areas. Rosewood oil treatment also prevented the ethanol-induced increase of interleukin-1ß, interleukin-6, tumor necrosis factor α (TNF-α), and neurofilament light chain (NFL) levels. These findings provide the first evidence that Rosewood oil intranasal administration exerts protective effects against emotional and molecular impairments associated with adolescent ethanol binge-like exposure, possibly due to linalool actions triggering neurotrophic factors, rebalancing antioxidant status, and attenuating proinflammatory process.
ABSTRACT
AIMS: Peripheral cortisol represents one biological measure of the hypothalamic-pituitary-adrenal (HPA) axis, a significant component of the stress system, which is altered by chronic alcohol consumption. However, whether heavy alcohol use affects the HPA axis differentially between the sexes and whether basal cortisol levels are a biomarker of prospective alcohol intake is unknown. METHODS: We recruited light moderate (LM) and binge-heavy (BH) drinkers of alcohol (n = 118). Repeated fasting morning cortisol levels were studied over a 2-hour period to assess basal levels while participants underwent a neuroimaging scan. RESULTS: Significantly higher average cortisol levels in BH compared to LM groups across four timepoints were observed (P < .018). Overall sex differences were observed with women showing higher initial cortisol levels at the first timepoint with a blunted decrease over the morning relative to men (P < .003). Average morning cortisol differentially predicted prospective future 30-day daily reports of alcohol consumption by sex and group, such that LM males had a positive significant relationship and BH males had a negative non-significant relationship between cortisol and drinking. CONCLUSIONS: Findings indicate that morning plasma cortisol is upregulated in the BH vs. LM group. Although females had higher initial morning cortisol levels, BH males showed a dysregulated negative relationship between stress and binge drinking in contrast to the LM group. Future work should further investigate the role of cortisol and other stress hormones as biomarkers of problematic drinking behaviors in men and women.

Background: Sociosexuality-attitudes, behaviors, and desires related to casual sex-partly predicts drinking behavior in both men and women because drinking is thought to facilitate interactions that lead to casual sex. It follows that sociosexuality would predict drinking intake (e.g., quantity consumed)-but perhaps not drinking consequences (e.g., blacking out)-on the premise that drinking large quantities with high frequency (but not to such high degrees/levels of intoxication that negative consequences occur) would facilitate casual sex. Objectives: This set of studies evaluated whether baseline measures of sociosexuality predict drinking intake (i.e., frequency, quantity, and binge drinking) but not experiencing blacking out at follow-up in two samples (Study 1, N = 172; Study 2, N = 1,038) of college-aged men. Results: As predicted, men's sociosexuality prospectively predicted drinking frequency, quantity, and binge drinking. Contrary to our predictions, men's sociosexuality also predicted blacking out. Conclusions: College men's drinking interventions should be tailored to high-risk groups and consider individual differences like sociosexuality.

Background: Stress is one of the main environmental factors involved in the onset of different psychopathologies. In youth, stressful life events can trigger inappropriate and health-damaging behaviors, such as binge drinking. This behavior, in turn, can lead to long-lasting changes in the neurophysiological response to stress and the development of psychological disorders late in life, e.g., alcohol use disorder. Our aim was to analyze the pattern of neurophysiological responses triggered with the exposition to a stressful virtual environment in young binge drinkers. Methods: AUDIT-3 (third question from the full AUDIT) was used to detect binge drinking (BD) in our young sample (age 18-25 years). According to the score, participants were divided into control (CO) and BD group. Next, a standardized virtual reality (VR) scenario (Richie's Plank) was used for triggering the stress response while measuring the following neurophysiological variables: brain electrical activity by electroencephalogram (EEG) and cortisol levels through saliva samples both measurements registered before and after the stressful situation. Besides, heart rate (HR) with a pulsometer and electrodermal response (EDA) through electrodes placed on fingers were analyzed before, during and after the VR task. Results: Regarding the behavior assessed during the VR task, BD group spent significantly less amount of time walking forward the table and a tendency toward more time walking backwards. There was no statistically significant difference between the BD and the CO group regarding time looking down, but when we controlled the variable sex, the BD women group displayed higher amount of time looking down than the rest of the groups. Neurophysiological measurements revealed that there was not any statistically significant difference between groups in any of the EEG registered measures, EDA response and cortisol levels. Sex-related differences were found in HR response to VR scenario, in which BD women displayed the highest peak of response to the stressor. Also, the change in heartbeat was higher in BD women than men. Conclusion: Unveiling the neurophysiological alterations associated with BD can help us to prevent and detect early onset of alcohol use disorder. Also, from our data we conclude that participants' sex can modulate some stress responses, especially when unhealthy behaviors such as BD are present. Nevertheless, the moment of registration of the neurophysiological variables respect to the stressor seems to be a crucial variable.

Background/Objective: The aim of the study was to evaluate the diagnostic usefulness of changes in transferrin isoforms, especially disialo-Tf, in identifying binge drinking children and adolescents admitted to hospital emergency. Methods: The study group consisted of 122 ambulatory children and adolescents below 18 years of age and 30 healthy subjects. From the group of drinkers, those with acute alcohol intoxication (AAI) were identified (ICD-11, code F10.0). The isoforms of transferrin were separated by capillary electrophoresis into five major fractions: asialo-Tf, disialo-Tf, trisialo-Tf, tetrasialo-Tf, and pentasialo-Tf. The differences between binge drinking youth and nondrinking subjects were evaluated by Mann-Whitney U-test. Results: In the total study group and in both genders, the concentration of disialo-Tf was significantly higher in the binge drinkers compared to the nondrinking youth (p = 0.006). With respect to the gender, the level of disialo-Tf was significantly higher in binge drinking than nondrinking girls (p = 0.028) and the value of trisialo-Tf was lower in binge drinking than nondrinking boys (p = 0.011). In the AAI subgroup, the concentrations of disialo-Tf and tetrasialo-Tf were significantly higher in comparison to nondrinking subjects (p = 0.002, p = 0.039, respectively). There were no significant correlations between the BAC and the transferrin isoforms in the total group and the AAI subgroup. The disialo-Tf reached the highest diagnostic power (AUC = 0.718) in identifying binge drinkers at diagnostic specificity and sensitivity of 86.7% and 51.6%, respectively (at cut-off 0.70), in the total group and it was growing up to AUC = 0.761 with the diagnostic sensitivity of 60% in the AAI subgroup. Conclusions: The disialo-Tf might be a useful biomarker to identify binge drinking children and adolescents.
ABSTRACT
Adolescent alcohol use has significant consequences for concurrent and longitudinal health and wellbeing, with sexual minority youth consistently reporting higher levels of alcohol use than their heterosexual peers. Understanding how individual-difference variables like aggressive behavior are associated with variability in sexual minority adolescents' higher levels of alcohol use offers novel theoretical insight into this vulnerability. The 81,509 participants were drawn from the Profiles of Student life: Attitudes and Behavior Study. They were ages 14-17 years (M = 15.38, SD = 1.09) and 50.1% were cisgender girls. For sexual identity, 88% were heterosexual, 5% were mostly heterosexual, were 4% bisexual, were 1% mostly gay or lesbian, and were 1% being gay or lesbian. Participants reported on alcohol use, aggressive behavior, and sexual identity. Gay/lesbian and mostly gay/lesbian adolescents who reported higher aggressive behavior had higher levels of alcohol use than their heterosexual peers who also reported higher aggressive behavior. The way in which aggressive behavior amplified the link between mostly gay/lesbian and gay/lesbian identities and alcohol use suggests the need for more research examining how this trait may heighten both exposure and reaction to minority stressors among some subgroups of sexual minority youth.
ABSTRACT
Alcohol-impaired driving is a formidable public health problem in the United States, claiming the lives of 37 individuals daily in alcohol-related crashes. Alcohol-impaired driving is affected by a multitude of interconnected factors, coupled with long delays between stakeholders' actions and their impacts, which not only complicate policy-making but also increase the likelihood of unintended consequences. We developed a system dynamics simulation model of drinking and driving behaviors among adolescents and young adults. This was achieved through group model building sessions with a team of multidisciplinary subject matter experts, and a focused literature review. The model was calibrated with data series from multiple sources and replicated the historical trends for male and female individuals aged 15 to 24 from 1982 to 2020. We simulated the model under different scenarios to examine the impact of a wide range of interventions on alcohol-related crash fatalities. We found that interventions vary in terms of their effectiveness in reducing alcohol-related crash fatalities. In addition, although some interventions reduce alcohol-related crash fatalities, some may increase the number of drinkers who drive after drinking. Based on insights from simulation experiments, we combined three interventions and found that the combined strategy may reduce alcohol-related crash fatalities significantly without increasing the number of alcohol-impaired drivers on US roads. Nevertheless, related fatalities plateau over time despite the combined interventions, underscoring the need for new interventions for a sustained decline in alcohol-related crash deaths beyond a few decades. Finally, through model calibration we estimated time delays between actions and their consequences in the system which provide insights for policymakers and activists when designing strategies to reduce alcohol-related crash fatalities.
ABSTRACT
Women veterans (WV) are a fast-growing population in the United States with concerning health disparities. Reports of increased risks of cardiovascular disease (CVD) and poorer health are evident in WV compared with their civilian counterparts. The transition from active duty to veteran poses additional life stressors, causing changes in health behaviors such as unhealthy alcohol consumption and decreased physical activity, which may explain health disparities in WV. The changes in these two health risk behaviors may be influenced by each other, and emerging evidence suggests that physical activity aids in managing alcohol consumption during alcohol use treatment. In this general narrative review, we summarized findings from studies involving WV on (1) the associations between alcohol consumption and physical activity and (2) the effect of physical activity on reducing alcohol use. We also discussed the clinical consideration of adding physical activity to alcohol use interventions for WV. Most of the literature included in this review has been based on predominantly veteran men populations. This knowledge gap highlights the importance of continued efforts and research studies targeting WV to eliminate health disparities among them.
ABSTRACT
The aim of this study was to evaluate the possible impact of the COVID-19 pandemic on prevalence rates and self-reported changes in patterns of alcohol use among first-year university students in Spain, considering the risk of problematic alcohol use. A serial cross-sectional study based on the uniHcos project was carried out. Data from 10 518 first-year university students (73.3% female, mean age 19 (SD = 1.6)) collected between 2012 and 2022 were analysed. The evolution of the pooled prevalence rates during the time series was analysed and the risk of problematic alcohol consumption was assessed using the AUDIT. Also, self-reported changes in alcohol use patterns during the pandemic were assessed. According to the results, during the COVID-19 pandemic, the prevalence of alcohol use in the past 30-days was reduced (76.3% in 2019 vs. 63.7% in COVID-19) increasing again in the New Normal period. Thus, a similar pattern in the practice of binge drinking was observed. Regarding the AUDIT score, 21.7% (95%CI 20.9, 22.6) of the students had harmful alcohol consumption, with a higher proportion among males. In the multivariable logistic models, a higher AUDIT score was significantly associated (p-value < 0.001) with being male and living with roommates. According to self-reported changes in consumption patterns during the COVID-19 pandemic, a higher proportion of participants with harmful use reported an increase in alcohol consumption compared to those at low-risk (43% vs 19%). Finally, despite the overall reduction in drinking prevalence during COVID-19, changes were not equal for all students and depended on their previous level of problematic drinking, highlighting that this should be considered in the development of strategies against alcohol use in this population.
ABSTRACT
BACKGROUND: This study examined reasons not to drink in young adults in relation to demographics, alcohol use patterns, timing (weekend vs. weekday), and typical drinking motives. METHODS: Young adults who reported past 30-day alcohol use and at least one nondrinking day (n = 614; mean age = 21.5 years ±0.53) completed a survey of alcohol-related measures (e.g., typical drinking motives) and up to 14 daily surveys that included 12 reasons not to drink assessed on nondrinking days. Multilevel logistic regressions were estimated for each reason not to drink and related covariates. RESULTS: The most common reasons not to drink on a given day were "wasn't interested in drinking" (83.4% of nondrinking days) and "didn't want to get drunk" (81.8% of nondrinking days), with over 96% of participants endorsing each of these at least once. On days (11.6%; by 29.5% of participants) when another drug was used instead of alcohol, 81.8% used cannabis. Sex, race/ethnicity, weekend (vs. weekday), and drinking motives were differentially linked to reasons not to drink. Reporting high-intensity drinking (i.e., ≥10 drinking on a day) versus binge (5-9 drinks on a day) in the past 2 weeks was linked to "had a hangover recently" (odds ratio = 2.85) as a reason not to drink. CONCLUSIONS: Findings suggest that reasons not to drink reflect personal decisions and highlight ways to acknowledge situational barriers (e.g., saving money for food and essentials) that can be emphasized in brief interventions. Furthermore, reasons not to drink and alcohol motives may work in tandem within the motivational model to impact alcohol use behaviors.
ABSTRACT
BACKGROUND: Binge drinking has been linked to traumatic dental injury (TDI). Once drunk, adolescents are more prone to accidents, which may result in orofacial injury. AIM: This study evaluated the possible association of binge drinking with a number of traumatised teeth in a population of 12-year-old Brazilian adolescents in 2013 and 2015. DESIGN: This study was longitudinal, carried out with 588 adolescents at two moments, 2013 and 2015. TDI, overjet and lip protection were assessed by calibrated examiners. Binge drinking data were collected through the Alcohol Use Disorders Identification Test. Sociodemographic indicators were obtained through a questionnaire answered by the parents/guardians. The Poisson regression model with a random effects intercept was estimated. RESULTS: A higher prevalence of traumatised teeth was observed among adolescents who binge drink (IRR = 1.37; 95% CI: 1.05-1.80; p < .05). The prevalence was also significantly higher among adolescents in this age range with a ≥ 3-mm overjet and those with inadequate lip protection (IRR = 1.99; 95% CI: 1.44-2.76; p < .001 and IRR = 3.41; 95% CI: 2.57-4.53; p < .001, respectively). CONCLUSION: A greater number of traumatised teeth were found among adolescents who reported binge drinking and had severe overjet and inadequate lip coverage.
ABSTRACT
There are over 1.4 million adolescents living with HIV in sub-Saharan Africa, the majority of whom acquired the virus through perinatal transmission (PHIV). HIV stigma is particularly high among adolescents living with HIV and is associated with several outcomes that worsen health and increase the risk of onward HIV transmission. We tested associations between internalized HIV stigma and four of these outcomes over a one-year period among a sample of adolescent boys living with PHIV in Soweto, South Africa. Participants (N = 241) answered questions about internalized HIV stigma at baseline. They completed weekly mobile surveys over the following year to answer questions about their experiences with depression, binge drinking, medication adherence, and violence victimization. Using generalized linear mixed models, we found that baseline internalized HIV stigma was associated with increased odds of depression (OR 1.74), alcohol misuse (OR 2.09), and violence victimization (OR 1.44) and decreased odds of medication adherence (OR 0.60) over the course of a year. These outcomes negatively impact the health and wellbeing of adolescents living with PHIV and increase their risk of transmitting HIV to their partners in the future. Our findings provide novel, longitudinal evidence for the deleterious effects of HIV stigma. To improve health outcomes for adolescents with PHIV, it will be crucial to develop effective HIV stigma reduction interventions that address specific developmental, gendered, and cultural experiences.
ABSTRACT
Aripiprazole has been linked to the development of impulse control problems (ICPs), most commonly gambling. Aripiprazole's effect on serotonergic and dopaminergic pathways has had mixed results on drinking behaviors. A male patient receiving outpatient psychiatric care presented with ongoing symptoms of depression on his current regimen of mirtazapine and gabapentin. Aripiprazole was chosen for augmentation after multiple failed trials of alternative medications. Within 3 weeks the patient discontinued the medication due to escalating binge-drinking behavior. This behavior resolved within 3 days after discontinuing aripiprazole. Individuals who engage in binge drinking demonstrate consistent impulse control deficits that are unrelated to the rewarding effects of alcohol. Aripiprazole may be related to this patient's return to binge drinking from an ICP standpoint rather than driven by alcohol cravings as other psychosocial factors remained stable throughout this time.
ABSTRACT
Aims: Harmful patterns of alcohol consumption, such as binge drinking, are prevalent among the student population at universities. Despite the risks of this behaviour, few secondary prevention programmes have been created to meet the specific needs of this population. The PEERCARE programme is a peer-based prevention programme that seeks harm reduction for alcohol overuse in party environments, among other goals. To do so, a "chill-out" space is created by peer educators in party environments to limit the risks associated with alcohol overuse. This study sought to examine peer educators' experience with a chill-out space to identify their specific actions, difficulties and needs, and to consider possibilities for improvement. Methods: Nine engineering students from one French grandes écoles campus trained as peer educators (six men and three women; mean age 21 years) participated. Semi-structured interviews were used for data collection. Results: The thematic analysis showed that the peer educators were highly engaged with this programme in response to alcohol overuse on their campus. The chill-out space was lauded for its non-judgemental and non-moralising nature. In addition, the numerous risk reduction activities that were enacted confirmed the benefits of these spaces during parties. The peer educators' experience was positive, and acting as managers of the chill-out space seemed to answer to a sense of competence recognitiontion. Conclusion: This study confirms the relevance of utilising chill-out spaces during parties and provides preliminary data on the deployment and management of peer-led chill-out space approaches. Expanding the implementation of such spaces to more educational institutions is recommended.
ABSTRACT
This cross-sectional study, carried out between October and December 2020 in two Brazilian cities, aimed to evaluate the joint association of education and sex with habitual and episodic excessive alcohol consumption during the COVID-19 pandemic. Habitual alcohol consumption was defined as drinking any quantity of alcohol at least once per week. Excessive episodic alcohol consumption was defined as the consumption of five or more drinks by men or four or more drinks by women at least once in the last 30 days. Adjusted multivariate logistic regression models were used to analyze associations of education and sex with alcohol consumption. Education was not associated with habitual alcohol consumption and excessive episodic alcohol consumption. However, when evaluating the joint effect between education and sex, it can be seen that men with low education were more likely to habitually consume (OR: 5.85; CI95:2.74-14.84) and abuse alcohol (OR: 4.45; IC95:1.54-12.82) and women with high education were more likely to have habitual (OR: 2.16; IC95:1.18-3.95) and abusive alcohol consumption (OR: 2.00; IC95:1.16-3.43). These findings highlight the modifying effect of sex on the relationship between education and alcohol consumption, such that education influenced alcohol consumption differently between sexes during the pandemic.

People are able to voluntarily suppress unwanted thoughts or memories, a phenomenon known as suppression-induced forgetting or memory suppression. Despite harmful alcohol use, such as binge drinking, has been linked to impaired inhibitory control (IC) and augmented alcohol-cue reactivity, no study to date has assessed memory inhibition abilities towards alcohol-related cues in binge drinkers (BDs). Thus, the present preregistered study aimed to evaluate the behavioral and neurofunctional mechanisms associated with memory inhibition, specifically those related to the suppression of alcohol-related memories, in young BDs. For this purpose, electroencephalographic activity was recorded in eighty-two college students aged between 18 and 24 years old from the University of Minho (50% females; 40 non/low-drinkers [N/LDS] and 42 BDs) while they performed the Think/No-Think Alcohol task. Brain functional connectivity (FC) was calculated using the phase locking value and, subsequently, a dynamic seed-based analysis was conducted to explore the FC patterns between IC and memory networks. Comparatively to N/LDs, BDs exhibited decreased alpha-band FC between the anterior cingulate cortex and the left fusiform gyrus during attempts to suppress non-alcohol memories, accompanied by unsuccessful forgetting of those memories. Conversely, BDs displayed augmented gamma-band FC between the IC network and memory regions -i.e., hippocampus, parahippocampus and fusiform gyrus- during suppression of alcohol-related memories. Inhibitory abnormalities in BDs may lead to hypoconnectivity between IC and memory networks and deficient suppression of non-alcohol-related memories. However, while suppressing highly salient and reward-predicting stimuli, such as alcohol-related memories, BDs display a hyperconnectivity pattern between IC and memory networks, likely due to their augmented attention towards intrusive alcoholic memories and the attempts to compensate for potential underlying IC deficits. These findings hold important implications for alcohol research and treatment, as they open up new avenues for reducing alcohol use by shifting the focus to empowering suppression/control over alcohol-related memories.
