Gender Differences in the Epidemiology of Alcohol Use and Related Harms in the United States

Latent classes of eating disorders and addictions by sex: Implication of alexithymia and stressful life events in youths

Introduction

Eating disorders (EDs) and behavioural addictions show common psychological vulnerability factors such as alexithymia and stressful life events (SLE). This study aims, firstly, to explore the prevalence and latent profiles of participants based on their risk of suffering EDs, gambling disorder (GD), alcohol and/or drug abuse, and compulsive buying (CB) by sex. Secondly, it aimed to test whether alexithymia and having experienced SLE are associated with group membership.

Methods

The sample was predominantly drawn from university students and social networks. It was composed of 352 young adults between 18 and 35 years old, of whom 77.8% were women and 22.2% men.

Results

The results showed that the most prevalent disorders of the sample were alcohol, EDs, CB, drugs and GD, respectively. Moreover, latent class analyses were conducted based on the risk of suffering EDs or addictions by sex. Three main profiles were found: 'Men with addictions', 'Healthy women' and 'Women with EDs'. Finally, differences in SLE and alexithymia levels were tested by latent classes. "Men with addictions" and "Women with EDs" had higher scores on alexithymia and SLE than the group of "Healthy women". However, the group of "Women with EDs" (class 3) reported significantly higher levels of SLE and alexithymia than the other two groups.

Discussion and conclusion

In conclusion, we discuss the possibility that some vulnerability factors operate generally and transdiagnostically in EDs and addictive disorders. The identification of clinical phenotypes could complement and deepen prediction, prevention and treatment research in clinical settings. The need to take sex and gender differences into account is reinforced.

Transgender and gender diverse adults' reflections on alcohol counseling and recommendations for providers

Transgender and gender diverse (TGD) populations experience health disparities due to societal stigma that increases TGD individuals' sources of stress and decreases access to health protective resources. Research has linked experiences of stigma to risky alcohol use, yet there remains a dearth of culturally sensitive alcohol use interventions that meet the needs of TGD people. The present study was conducted to inform modifications to the content and delivery of an existing brief, telehealth, motivational intervention to decrease at-risk alcohol use among TGD adults. Individual semi-structured in-depth qualitative interviews were conducted with TGD adults who reported recent alcohol use (n = 18) to explore factors that facilitate positive interactions with health care providers and identify relevant information for alcohol use disorder treatment. Participants were recruited from an LGBTQ +-focused health center in Los Angeles, California. Two major themes and recommendations emerged: (a) A multicultural orientation of humility is important to develop productive therapeutic relationships with TGD clients when delivering motivational interviewing; (b) Due to insufficient appropriate data on alcohol use and health in TGD populations, feedback used in motivational alcohol counseling needs to be modified to better serve TGD clients. These findings show that counselors' philosophy and behavior, as well as session content, need to be considered when working with TGD populations within the context of alcohol counseling. These findings also have implications for intervention development, clinical treatment, and future research. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Are restrictions in sales hours of alcohol associated with fewer emergency room visits in Lithuania? An interrupted time-series analysis

INTRODUCTION

On 1 January 2018, an amendment to the alcohol control law was introduced in Lithuania which, among other changes, reduced trading hours for alcoholic beverages by 4 h for weekdays and Saturdays, and by 9 h for Sundays. The objective of the current study was to quantify the potential association of this law with the numbers and types of emergency room (ER) visits in Lithuania, in general and specifically for Sundays, for all ER visits, for injury-related ER visits and specifically for alcohol poisoning as a 100% alcohol-attributable cause.

METHODS

Sex-stratified time-series analysis-based models for the period 2016-2019 were used to test for associations and for potential alternative explanations (e.g., the increase in minimum legal drinking age, which occurred at the same time).

RESULTS

Overall, while the reduction in sales hours for both sexes was associated with slight increases in all types and in injury-related ER visits on a weekly basis, the association with ER visits for alcohol poisoning was in the opposite direction for men in all models. Specifically, among men, it was associated with an approximate decrease of 20% of alcohol poisoning-related ER visits on Sundays and an approximate decrease of 12% of alcohol poisoning-related ER visits for all seven weekdays.

DISCUSSION AND CONCLUSIONS

As predicted, restrictions on availability were associated with marked reductions in ER visits for alcohol poisoning in men. However, contrary to expectations, there were no overall reductions in overall ER visits, nor reductions in injury-related ER visits.

The developmental unfolding of substance use disorder symptoms and academic achievement in the transition into and out of college

This study aimed to explore the prospective associations between both alcohol and cannabis use (frequency and DSM-5 substance use disorder symptom counts) as they relate to academic performance over a period of ∼ four years. The study members were students enrolled in college in the Southeastern United States (N = 209, 62 % female, 90 % white). Baseline survey data were obtained in the first year of college while participants finished the follow-up assessments ∼ 1 and ∼ 4 years from baseline (80+ % retention rates). We aimed to tease apart antecedent from consequence in the associations between substance use and academic performance using a sophisticated modeling technique that accounts for between-person influences in evaluating within-person change over time. Results showed that greater alcohol use disorder symptoms in the first year of college were associated with a within-person decline in grades in the second year of college. This was not demonstrated for alcohol or cannabis frequency, alcohol quantity, or cannabis use disorder symptoms or in relation to the later developmental transition out of college. In addition to widely implemented prevention efforts, these results indicate that screening first-year college students for alcohol use disorder symptoms and connecting them with resources and treatment may be beneficial in attempts to promote academic performance.

Women, alcohol consumption and health promotion: the value of a critical realist approach

Research on women's drinking occurs in largely disparate disciplines-including public health, health promotion, psychology, sociology, and cultural studies-and draws on differing philosophical understandings and theoretical frameworks. Tensions between the aims and paradigmatic underpinnings of this research (across and within disciplines) have meant that knowledge and insight can be frequently disciplinary-specific and somewhat siloed. However, in line with the social and economic determinants of the health model, alcohol research needs approaches that can explore how multiple gender-related factors-biological, psycho-social, material, and socio-cultural-combine to produce certain drinking behaviours, pleasures and potential harms. We argue that critical realism as a philosophical underpinning to research can accommodate this broader conceptualization, enabling researchers to draw on multiple perspectives to better understand women's drinking. We illustrate the benefit of this approach by presenting a critical realist theoretical framework for understanding women's drinking that outlines interrelationships between the psychoactive properties of alcohol, the role of embodied individual characteristics and the material, institutional and socio-cultural contexts in which women live. This approach can underpin and foster inter-disciplinary research collaboration to inform more nuanced health promotion practices and policies to reduce alcohol-related harm in a wide range of women across societies.

Gambling Among Underage Alcohol Users Between 2008 and 2019: A National Cross-Sectional Study Among Finnish Adolescents

PURPOSE

The aim of this study is to examine trends in the relationship between gambling, alcohol use, and drunkenness between genders in Finland from 2008 through 2019.

METHODS

Data were based on six waves (2008-2009, 2010-2011, 2013, 2015, 2017, 2019) of a national cross-sectional School Health Promotion Study. The survey was conducted during a school day among eighth graders (14-15 years old) and ninth graders (15-16 years old) in Finland. The changes in gambling frequency among boys and girls were studied (regular gambling: at least once a week; occasional gambling: 2-3 times a month to less than once a month; no gambling during the previous year), alcohol use (at least once a month), and drunkenness (at least once a month).

RESULTS

The prevalence of adolescent gambling was more than halved between 2008 and 2019. However, the difference between the adolescents with the most favorable outcome (those who were not gambling and used alcohol or were getting drunk less often than once a month) and the adolescents with the least favorable outcome (boys who gambled, used alcohol, or were getting drunk; girls who were gambling regularly and getting drunk or gambling occasionally, using alcohol, and getting drunk) was larger in 2019 than in 2008.

DISCUSSION

These larger differences between adolescents indicate that there has been a polarization of problems between adolescents, and for some individuals, problems are clustering. There is a strong case to be made for protecting adolescents from these risk behaviors and their adverse consequences on multiple levels.

Temperature-related mortality in China from specific injury

Injury poses heavy burden on public health, accounting for nearly 8% of all deaths globally, but little evidence on the role of climate change on injury exists. We collect data during 2013-2019 in six provinces of China to examine the effects of temperature on injury mortality, and to project future mortality burden attributable to temperature change driven by climate change based on the assumption of constant injury mortality and population scenario. The results show that a 0.50% (95% confident interval (CI): 0.13%-0.88%) increase of injury mortality risk for each 1 °C rise in daily temperature, with higher risk for intentional injury (1.13%, 0.55%-1.71%) than that for unintentional injury (0.40%, 0.04%-0.77%). Compared to the 2010s, total injury deaths attributable to temperature change in China would increase 156,586 (37,654-272,316) in the 2090 s under representative concentration pathways 8.5 scenario with the highest for transport injury (64,764, 8,517-115,743). Populations living in Western China, people aged 15-69 years, and male may suffer more injury mortality burden from increased temperature caused by climate change. Our findings may be informative for public health policy development to effectively adapt to climate change.

Gamma-aminobutyric acid (GABA) can affect physiological processes in preimplantation embryos via GABAA and GABAB receptors

Purpose

Several widely used substances (e.g., some therapeutics or food supplements) can act on gamma-aminobutyric acid (GABA) receptors, and we investigated whether the activation of these receptors could affect the preimplantation embryo.

Methods

Transcripts of all GABA receptor subunits and selected proteins were examined using quantitative RT-PCR and immunohistochemistry. To analyze the effects of receptor activation, in vitro culture of mouse preimplantation embryos with natural and synthetic GABA receptor ligands was used.

Results

We detected nine GABA receptor transcripts in mouse blastocysts and 14 GABA receptor transcripts in ovulated oocytes. The results of this study indicate that ionotropic GABA_A receptors can be formed from α5, β3, and γ3 (or δ, π) subunits, GABA_A-ρ receptors can be formed from ρ2 subunits and metabotropic GABA receptors can be formed from GABA_B1b and GABA_B2 subunits in mouse blastocysts. Supplementing the culture medium with GABA at concentrations of 2-10 mM or with specific GABA_A and GABA_B receptor agonists (at concentrations of 10-100 μM) significantly increased the proportion of dead cells in blastocysts. The GABA-induced effects were prevented by pretreatment of embryos with GABA_A and GABA_B receptor antagonists.

Conclusion

The results of this study indicate that GABA and synthetic GABA receptor ligands can negatively affect preimplantation embryos via GABA_A and GABA_B receptors.

Triple Diagnosis of Attention-Deficit/Hyperactivity Disorder with Coexisting Bipolar and Alcohol Use Disorders: Clinical Aspects and Pharmacological Treatments

Attention-Deficit/Hyperactivity Disorder (ADHD), Bipolar Disorder (BD) and Alcohol Use Disorder (AUD) are common medical conditions often coexisting and exerting mutual influence on disease course and pharmacological treatment response. Each disorder, when considered separately, relies on different therapeutic approaches, making it crucial to detect the plausible association between them. Treating solely the emerging condition (e.g., alcoholism) and disregarding the patient's whole psychopathological ground often leads to treatment failure and relapse. Clinical experience and scientific evidence rather show that tailoring treatments for these three conditions considering their co-occurrence as a sole complex disorder yields more fulfilling and durable clinical outcomes. In light of the above considerations, the purpose of the present review is to critically discuss the pharmacological strategies in the personalized treatment of complex conditions defined by ADHD-bipolarityalcoholism coexistence.

Epidemiology and Disease Burden of Alcohol Associated Liver Disease

Consumption of alcohol in excess leads to substantial medical, economic, and societal burdens. Approximately 5.3% of all global deaths may be attributed to alcohol consumption. Moreover, the burden of alcohol associated liver disease (ALD) accounts for 5.1% of all disease and injury worldwide. Alcohol use disorder (AUD) affects men more than women globally with significant years of life loss to disability in low, middle and well-developed countries. Precise data on global estimates of alcohol related steatosis, alcohol related hepatitis, and alcohol related cirrhosis have been challenging to obtain. In the United States (US), alcohol related steatosis has been estimated at 4.3% based on NHANES data which has remained stable over 14 years. However, alcohol-related fibrotic liver disease has increased over the same period. In those with AUD, the prevalence of alcohol related hepatitis has been estimated at 10-35%. Globally, the prevalence of alcohol-associated cirrhosis has been estimated at 23.6 million individuals for compensated cirrhosis and 2.46 million for those with decompensated cirrhosis. The contribution of ALD to global mortality and disease burden of liver related deaths is substantial. In 2016 liver disease related to AUD contributed to 50% of the estimated liver disease deaths for age groups 15 years and above. Data from the US report high cost burdens associated with those admitted with alcohol-related liver complications. Finally, the recent COVID-19 pandemic has been associated with marked increase in alcohol consumption worldwide and will likely increase the burden of ALD.

Sexually dimorphic development of the mesolimbic dopamine system is associated with nuanced sensitivity to adolescent alcohol use

Alcohol use remains a major public health concern and is especially prevalent during adolescence. Adolescent alcohol use has been linked to several behavioral abnormalities in later life, including increased risk taking and impulsivity. Accordingly, when modeled in animals, male rats that had moderate alcohol consumption during adolescence exhibit multiple effects in adulthood, including increased risk taking, altered incentive learning, and greater release of dopamine in the mesolimbic pathway. It has been proposed that alcohol arrests neural development, "locking in" adolescent physiological, and consequent behavioral, phenotypes. Here we examined the feasibility that the elevated dopamine levels following adolescent alcohol exposure are a "locked in" phenotype by testing mesolimbic dopamine release across adolescent development. We found that in male rats, dopamine release peaks in late adolescence, returning to lower levels in adulthood, consistent with the notion that high dopamine levels in adolescence-alcohol-exposed adults were due to arrested development. Surprisingly, dopamine release in females was stable across the tested developmental window. This result raised a quandary that arrested dopamine levels would not differ from normal development in females and, therefore, may not contribute to pathological behavior. However, the aforementioned findings related to risk-based decision-making have only been performed in male subjects. When we tested females that had undergone adolescent alcohol use, we found that neither risk attitude during probabilistic decision-making nor mesolimbic dopamine release was altered. These findings suggest that different developmental profiles of the mesolimbic dopamine system across sexes result in dimorphic susceptibility to alcohol-induced cognitive and motivational anomalies exposure.

The role of gender and veteran status in healthcare access among a national sample of U.S. adults with unhealthy alcohol use

Background: Routine healthcare access is critical to reduce drinking and its effects, yet little is known about Veteran and gender differences in routine healthcare access among unhealthy drinkers. The current study examined differences in routine healthcare access, stratified by Veteran status and gender, among a national sample of adults endorsing unhealthy drinking. Method: Using data from the Centers for Disease Control and Prevention's 2019 Behavioral Risk Factor Surveillance System National Survey, we identified adults who endorsed unhealthy drinking over the past month (N = 58,816; 41.4% female; 2.7% female Veterans). Bivariate and multivariable analyses modeled associations between gender, Veteran status, and their interaction in predicting routine healthcare access. All multivariable models adjusted for sociodemographic characteristics. Results: Veterans with unhealthy alcohol use reported high rates of routine healthcare access (e.g., >86% sought care in the past 2 years) and were less likely to experience a cost barrier to care (aOR = 0.75, 95% CI = 0.62-0.92). Females were more likely than males to report better access to care but also to experience a cost barrier (aOR = 1.2, 95% CI = 1.10-1.37). The interaction between Veteran status and gender was non-significant. Conclusions: Overall, healthcare access was better for Veterans and females with unhealthy alcohol use compared to civilians and males with unhealthy alcohol use. However, given that females were more likely to report a cost barrier, future implementation research aiming to improve equity in care may want to explore reasons for cost barriers and develop strategies to help reduce these barriers in order to eliminate gender disparities in primary care-based alcohol-related care.

Health Behaviors, Financial Difficulties, and Depressive Symptoms Among Older Adults Across Gender and Race During the COVID-19 Pandemic

Background: COVID-19 deeply affected the health and well-being of older adults. This study examines health behavior change and the interrelationships between health behaviors, financial difficulties, and depressive symptoms among older adults across gender and race during the pandemic. Methods: Using Rounds 1, 5, and 10 of the National Health and Aging Trends Study (NHATS) linked with the NHATS COVID-19 dataset, our sample included Medicare beneficiaries aged 65 or older in the U.S. (N = 3,118). We modeled the interrelationships between health behaviors, financial difficulties, and depressive symptoms using a structural equation model. Results: Female participants reported less walking, more changes in eating habits, less sleeping, and less alcohol consumption during the pandemic than before the pandemic compared to male participants. Compared to White, Non-White participants showed higher proportions of experiencing financial difficulties, less walking, less vigorous activity, and changes in time spent eating and sleeping during than before the pandemic. Financial difficulties was positively associated with depressive symptoms and sedentary behavior. Active behavior was negatively associated with depressive symptoms, while sedentary behavior was positively associated with more depressive symptoms. Discussion: Health professionals should consider health behaviors and financial difficulties when intervening on depressive symptoms experienced by older adults since the pandemic.

Linking Historical Discriminatory Housing Patterns to the Contemporary Alcohol Environment

Research on alcohol outlet density consistently shows greater disparities in exposure in disinvested communities. Likewise, structural racism via discriminatory housing practices has created many of the issues that beset contemporary disinvested neighborhoods. Little work, however, has examined the relationship between housing practices and alcohol outlet disparities. The central premise of our work is that these discriminatory and inequitable practices create distinctions in the alcohol environment, and that such disparities have implications for work on alcohol policy. Here we link alcohol outlet density with a spatial database examining redlining, blockbusting, and gentrification in Baltimore, Maryland, and Flint, Michigan (two cities with common experiences of urban disinvestment over the last 50 years). Standard measures are used to account for the impacts of neighborhood racial, socioeconomic, and housing composition in a multilevel model. Our findings highlight that gentrification and redlining are strongly associated with alcohol outlet density, while blockbusting is not. Gentrification and redlining also frequently co-occur in inner-urban areas, while the more suburban phenomenon of blockbusting rarely overlaps with either. These findings further contextualize nascent work on structural racism in housing that illustrates important disparities along the lines of these distinct practices. Future work should consider how legacy impacts of discriminatory housing patterns impact our communities today.

Drug use over time among never-deployed US Army Reserve and National Guard soldiers: The longitudinal effects of non-deployment emotions and sex

Some US military service members who have never been deployed experience negative emotions related to never having been deployed, and some work shows these non-deployment emotions (NDE) are cross-sectionally associated with hazardous drinking for male, but not female, US Army Reserve/National Guard (USAR/NG) soldiers. However, it is not known if these effects extend to drug use or persist longitudinally, which is the focus of the current study. We conducted a longitudinal residual change analysis of a subset of data (N = 182 never-deployed soldiers) from Operation: SAFETY, an ongoing survey-based study of USAR/NG soldiers recruited from units across New York State. Outcome measures included current tobacco use, non-medical use of prescription drugs (NMUPD), current cannabis use, and other current illicit drug use (excluding cannabis) at four time points over a 3-year period. Results from bootstrapped residual change generalized estimating equation (GEE) models show that more negative NDE were longitudinally associated with a greater likelihood of current NMUPD among male, but not female, soldiers (p < 0.05). NDE were not longitudinally associated with current tobacco use, cannabis use, or other illicit drug use among male or female soldiers (ps > 0.05). NDE may contribute to ongoing NMUPD among male USAR/NG soldiers who have never been deployed. Never-deployed soldiers, especially those with negative emotions related to never having been deployed, should not be overlooked in military screening and intervention efforts.

COVID-19 Racism, Depressive Symptoms, Drinking to Cope Motives, and Alcohol Use Severity Among Asian American Emerging Adults

The COVID-19 pandemic has incited widespread anti-Asian racism, which is linked to numerous behavioral health consequences including depressive symptoms. As racism-induced depressive symptoms are linked to coping-related alcohol use and because alcohol-related problems represent a significant public health concern in this population, we investigated whether COVID-19 racism predicted alcohol use severity through depressive symptoms and drinking to cope motives among Asian American emerging adults (N = 139; Mage = 23.04; 50% women, 50% men). We conducted a serial mediation wherein COVID-19 racism predicted alcohol use severity sequentially through depressive symptoms and drinking to cope motives. COVID-19 racism directly and significantly predicted alcohol use severity. The indirect effect via depressive symptoms and drinking to cope motives was also significant, suggesting that COVID-19 racism is likely a risk factor for alcohol-related problems. Results inform intervention science and highlight the need for policy and behavioral health services to curb COVID-19 racism.

Identification of clinical factors related to prediction of alcohol use disorder from electronic health records using feature selection methods

BACKGROUND

High dimensionality in electronic health records (EHR) causes a significant computational problem for any systematic search for predictive, diagnostic, or prognostic patterns. Feature selection (FS) methods have been indicated to be effective in feature reduction as well as in identifying risk factors related to prediction of clinical disorders. This paper examines the prediction of patients with alcohol use disorder (AUD) using machine learning (ML) and attempts to identify risk factors related to the diagnosis of AUD.

METHODS

A FS framework consisting of two operational levels, base selectors and ensemble selectors. The first level consists of five FS methods: three filter methods, one wrapper method, and one embedded method. Base selector outputs are aggregated to develop four ensemble FS methods. The outputs of FS method were then fed into three ML algorithms: support vector machine (SVM), K-nearest neighbor (KNN), and random forest (RF) to compare and identify the best feature subset for the prediction of AUD from EHRs.

RESULTS

In terms of feature reduction, the embedded FS method could significantly reduce the number of features from 361 to 131. In terms of classification performance, RF based on 272 features selected by our proposed ensemble method (Union FS) with the highest accuracy in predicting patients with AUD, 96%, outperformed all other models in terms of AUROC, AUPRC, Precision, Recall, and F1-Score. Considering the limitations of embedded and wrapper methods, the best overall performance was achieved by our proposed Union Filter FS, which reduced the number of features to 223 and improved Precision, Recall, and F1-Score in RF from 0.77, 0.65, and 0.71 to 0.87, 0.81, and 0.84, respectively. Our findings indicate that, besides gender, age, and length of stay at the hospital, diagnosis related to digestive organs, bones, muscles and connective tissue, and the nervous systems are important clinical factors related to the prediction of patients with AUD.

CONCLUSION

Our proposed FS method could improve the classification performance significantly. It could identify clinical factors related to prediction of AUD from EHRs, thereby effectively helping clinical staff to identify and treat AUD patients and improving medical knowledge of the AUD condition. Moreover, the diversity of features among female and male patients as well as gender disparity were investigated using FS methods and ML techniques.

A Genome-Wide Association Study Reveals a BDNF-Centered Molecular Network Associated with Alcohol Dependence and Related Clinical Measures

At least 50% of factors predisposing to alcohol dependence (AD) are genetic and women affected with this disorder present with more psychiatric comorbidities, probably indicating different genetic factors involved. We aimed to run a genome-wide association study (GWAS) followed by a bioinformatic functional annotation of associated genomic regions in patients with AD and eight related clinical measures. A genome-wide significant association of rs220677 with AD (p-value = 1.33 × 10^-8 calculated with the Yates-corrected χ² test under the assumption of dominant inheritance) was discovered in female patients. Associations of AD and related clinical measures with seven other single nucleotide polymorphisms listed in previous GWASs of psychiatric and addiction traits were differently replicated in male and female patients. The bioinformatic analysis showed that regulatory elements in the eight associated linkage disequilibrium blocks define the expression of 80 protein-coding genes. Nearly 68% of these and of 120 previously published coding genes associated with alcohol phenotypes directly interact in a single network, where BDNF is the most significant hub gene. This study indicates that several genes behind the pathogenesis of AD are different in male and female patients, but implicated molecular mechanisms are functionally connected. The study also reveals a central role of BDNF in the pathogenesis of AD.

Reported Cases of Alcohol Consumption and Poisoning for the Years 2015 to 2022 in Hail, Saudi Arabia

This study aimed to determine the pattern of alcohol consumption and its poisoning among the Saudi population in the city of Hail, KSA. Data from a retrospective cohort were collected qualitatively at King Khalid Hospital (KKH) and Hail General Hospital (HGH), covering 550 participants from 2015 to 2022. Two groups were formed comprising patients admitted to the emergency room (ER) and community members; their ages ranged from 19 to 75 years. Group 1 contained 400 participants, of which 250 were patients (244 males, six females) who came to the (ER) with a suspected alcohol overdose or poisoning, and 150 were patients (128 males and 22 females) who were discharged from the (ER) with minimal complaints because of their drinking. Group 2 comprised 150 participants (128 males, 22 females) who were community members, who were surveyed using a questionnaire or interview. In Group 1, 30% of patients reported an altered state of consciousness as a major complaint, 28.8% of patients exhibited abnormal liver function tests (LFTs), 27% had abnormal renal function tests (RFT) with decreased glomerular filtration rates (GFR) and elevated levels of urea and creatinine or low levels of electrolytes or calcium, and 35.6% patients showed elevated levels of pancreatic enzymes. One death was reported due to high alcohol consumption. In Group 2, the community participants reported that they started drinking alcohol due to the influence of other people (29%), stress (11%), depression (10.8%), curiosity (4.4%), and boredom (4%). In addition, 77% of participants were frequent alcohol drinkers and 20% consumed it daily. Further, 68.7% claimed to drink alcohol for more than one hour at a time, while 83.3% experienced blackouts and 70% had problems related to their liver. Moreover, 72.7% of the participants ended up in the hospital and 34.6% suffered from multiple chronic diseases. It is concluded that social influences and stress contributed to the initiation of alcohol use. Despite data gaps, the findings of this study provide a practical understanding of alcohol consumption among the Saudi population and guidance for policymakers.

An examination of cyberchondria's relationship with trait anxiety and psychological well-being in women of reproductive age: A cross-sectional study

Online environments have become the main sources of health-related information. However, if used incorrectly, this can decrease the level of well-being. Cyberchondria corresponds to the hypochondria in the digital age. We aimed to investigate the relationship between cyberchondria and trait anxiety, psychological well-being, and other factors in women of reproductive age. This study used a descriptive cross-sectional design. Face-to-face questionnaires were administered to women aged 18 to 49. The sample size was formed and stratified according to the population of the 47 family health centers to reflect the entire population. The questionnaire included a sociodemographic information form, the Cyberchondria Severity Scale (CSS), the State-Trait Anxiety Inventory, and the Psychological Well-Being Scale (PWBS). This study included 422 participants. The average daily use of the Internet was 2.14 ± 1.837 hours, while that of social media was 2.69 ± 2.027 hours. The mean CSS score was 89.42 ± 21.688; the mean trait anxiety score was 44.34 ± 8.791, and the mean PWBS score was 324.26 ± 35.944. Factors that interacted with the level of cyberchondria were the trait anxiety score, PWBS score, alcohol consumption, and average daily use of the internet and social media. Increased online time, alcohol consumption, trait anxiety levels, and psychological well-being increase cyberchondria levels. Improvements must be made in the accuracy of online information, which is unsupervised and easily accessible to society as a source of information. Future studies should focus on the prevention, detection, and treatment of cyberchondriasis. Identifying and improving the factors affecting women's and mothers' cyberchondria will also increase the chances of providing primary protection against certain diseases.

Seeking care where they can: A systematic review of global trends in online alcohol treatment utilization among non-veteran and veteran women

Background

Findings from a person-level meta-analysis of online alcohol intervention trials suggest that women disproportionately seek out such interventions (Riper et al., 2018). Although women may be a "hidden population" that is particularly drawn to online alcohol interventions, trial design features may explain women's apparent over-representation in these trials.

Methods

This systematic review examined associations between gender-tailored recruitment/inclusion criteria and proportions of women enrolled in online alcohol intervention trials, evaluated whether community samples have greater proportions of women than clinical samples, and compared country-specific average proportions of women in trials to country-specific proportions of women with Alcohol Use Disorder (AUD).

Results

Forty-four trials met inclusion/exclusion criteria, 34 community samples and 10 drawn from clinical settings; 4 studies included U.S. veterans and were examined separately. The average proportion of community-recruited women across the studies was 51.20% and the average proportion of clinically-recruited women was 35.81%, a difference that was statistically significant. Across the countries with relevant trials, the expected proportion of those with AUD who are women is 27.1% (World Population Review, 2022). Only 2 studies used targeted recruitment for women so no between-group tests were conducted. There was not a statistically significant difference in the proportion of women across trials that did and did not use gender-tailored alcohol inclusion criteria.

Conclusions

Results from this systematic review suggest that study design factors do not account for the marked over-representation of women in online alcohol interventions, indicating that women are indeed a "hidden population" whose needs should be understood and accommodated.

Neural cue reactivity is not stronger in male than in female patients with alcohol use disorder

BACKGROUND

Males consume more alcohol than females, and alcohol use disorder (AUD) is more prevalent in males than females. However, females progress faster to AUD. Sex differences in neural alcohol cue reactivity were previously observed in young social drinkers, indicating a role of hypersensitivity to alcohol-related cues in very early stages of addiction. To our knowledge, this is the first study on patients diagnosed with AUD to test sex differences in neural reactivity to alcohol cues in order to widen previous findings.

METHODS

We analyzed data from previous studies, using a well-established functional magnetic resonance imaging (fMRI) paradigm to compare neural reactivity to alcohol cues between 42 female and 124 male patients with AUD (mean age 45 and 46 years) in predefined regions of interest that were implicated by previous studies (ventral and dorsal striatum as well as caudate, putamen, amygdala, hippocampus, insula, anterior cingulate cortex, and medial prefrontal cortex) using independent samples t-tests. Post-hoc, effect size calculations were performed.

RESULTS

Throughout all nine regions of interest, we found no statistically significant sex differences in neural reactivity toward alcoholic pictures alone or in comparison to neutral pictures (p > 0.05, FDR-corrected). Post-hoc effect size estimates indicated a magnitude between 0.137 and 0.418 (Hedge's g) on alcohol reactivity to alcohol cues compared to neutral cues and indicate very small to less than medium effect sizes in the direction of higher cue reactivity in female patients.

CONCLUSION

Previous studies showed sex differences in neural alcohol cue reactivity in younger social and problematic alcohol drinkers, i.e., stronger striatal cue-reactivity in males. After correction for multiple comparisons, we did not observe significant sex differences in a cohort of middle-aged females and males with AUD. Sex differences that are present during early phases of addiction development might disappear at later stages of AUD and might thus be considered as clinically less relevant in patients with more severe AUD.

The Role of Gender in the Association between Mental Health and Potentially Preventable Hospitalizations: A Single-Center Retrospective Observational Study

Psychiatric disorders and substance abuse are barriers that limit access to timely treatment and can lead to Potentially Preventable Hospitalizations (PPH). The aim of this study is to identify the role played by gender in the association between mental health and PPH. Hospital discharge records (HDRs) from the Local Health Authority of Pescara (Italy) from 2015 to 2021 were examined and PPH were measured according to Prevention Quality Indicators (PQIs) provided by the Agency for Healthcare Research and Quality. In total, 119,730 HDRs were eligible for the study and 21,217 patients fell into the PQI categories. Mental health disorders and addictions were extracted from the HDRs through the Elixhauser Enhanced ICD-9-CM algorithm. The association between PQI hospitalization and some predictors considered was evaluated with multivariate logistic regression models. In males and females, alcohol abuse showed a protective role towards preventable admissions for PQI-90 (all types of conditions) and PQI-92 (chronic conditions). In contrast, there is a gender gap in accessibility to primary health care, especially for acute conditions leading to PPH. Indeed, in males, PQI-91 admissions for acute conditions were found to be positively associated with drug abuse, psychosis, and depression, whereas this was not the case for females.

The effect of alcohol use disorder symptom and recovery narratives on problem-recognition: A randomized online trial

BACKGROUND

Low problem recognition is a barrier to seeking treatment for alcohol use disorder ("AUD"). Promoting continuum belief narratives, which conceptualize AUD as a spectrum, together with narratives that promote non-abstinence recovery may boost self-recognition of risky drinking. This experimental study examines the effect of dichotomous vs continuous symptom narratives and non-abstinence vs abstinence recovery narratives on self-recognition of risky drinking among students.

METHODS

N = 489 participants were randomized to one of four interventions combining a continuous vs dichotomous AUD symptom narrative with an abstinence vs moderated drinking AUD recovery narrative in a 2×2 design. Participants completed demographic and alcohol use (AUDIT-C) preintervention measures and postintervention measures assessing self-recognition of risky drinking and endorsement of continuum beliefs.

RESULTS

Moderate drinking recovery narratives resulted in higher endorsement of continuum beliefs (F (1, 485) = 16.27, p <.001, η2p =.032 90 % CI [0.01, 0.06]). Recognizing own risky drinking behavior was unaffected by the interventions. However, in a subgroup of participants without prior AUD experience who met AUDIT-C criteria for risky drinking, the combination of a continuous symptom narrative and moderated drinking recovery narrative resulted in higher problem recognition (F (1, 48) = 5.79, p =.020, η2p =.10, 90 % CI [0.01, 0.25]).

CONCLUSIONS

Exposure to moderated drinking recovery narratives may help develop an awareness in young adults that problematic alcohol use exists on a spectrum. Among those at increased risk for AUD, exposure to narratives that promote a continuous model of AUD and non-abstinence recovery may increase problem recognition.

Public Health Measures and Prevention of Alcohol-Associated Liver Disease

Hazardous alcohol consumption causes approximately 4% of deaths globally, constituting one of the leading risk factors for the burden of the disease worldwide. Alcohol has several health consequences, such as alcohol-associated liver disease, hepatocellular carcinoma, nonliver neoplasms, physical injury, cardiac disease, and psychiatric disorders. Alcohol misuse significantly affects workforce productivity, with elevated direct and indirect economic costs. Due to the high impact of alcohol consumption on the population, public health has led to the development of a range of strategies to reduce its harmful effects. Regulatory public health policies (PHP) for alcohol can exist at the global, regional, international, national, or subnational levels. Effective strategies incorporate a multilevel, multicomponent approach, targeting multiple determinants of drinking and alcohol-related harms. The World Health Organization categorizes the PHP into eight categories: national plan to fight the harmful consequences of alcohol, national license and production and selling control, taxes control and pricing policies, limiting drinking age, restrictions on alcohol access, driving-related alcohol policies, control over advertising and promotion, and government monitoring systems. These policies are supported by evidence from different populations, demonstrating that determinants of alcohol use depend on several factors such as socioeconomic level, age, sex, ethnicity, production, availability, marketing, and others. Although most policies have a significant individual effect, a higher number of PHP are associated with a lower burden of disease due to alcohol. The excessive consequences of alcohol constitute a call for action, and clinicians should advocate for developing and implementing a new PHP on alcohol consumption.

Analysis of alcohol use, consumption of micronutrient and macronutrients, and liver health in the 2017-2018 National Health and Nutrition Examination Survey

BACKGROUND

Alcohol use is a major global healthcare burden that contributes to numerous adverse health outcomes, including liver disease. Many factors influence individual susceptibility to alcohol-associated diseases, including nutritional factors. The objective of the current study was to examine inter-relations among alcohol, dietary micronutrients and macronutrient consumption, and liver health by analyzing data from the 2017-2018 National Health and Nutrition Examination Survey (NHANES).

METHODS

Based on self-reported alcohol consumption, NHANES respondents were assigned to one of four categories: never drinkers (lifetime abstainers), non-drinkers (past-year abstainers), moderate drinkers (1/2 drinks per day for females/males, respectively), and heavy drinkers (>1/>2 drinks per day for females/males, respectively, and/or frequent binge drinking). Survey-weighted regression analyses (adjusted for gender, age, race, education, and body mass index) were performed to examine associations between alcohol intake, dietary, and liver health characteristics.

RESULTS

Individuals categorized as heavy drinkers were significantly younger, most often well-educated males with low incidences of diabetes and other comorbidities. They consumed the most overall calories and various micronutrients, indicating a diet that was not necessarily nutrient poor. Neither moderate nor heavy drinkers had liver steatosis or fibrosis as measured by liver elastography, although heavy drinkers had modestly elevated plasma biomarkers of liver injury, including ALT, AST, and GGT, compared with the other groups.

CONCLUSIONS

Our findings suggest that the category of heavy drinkers in the 2017-2018 NHANES consisted of generally healthy individuals with high-energy intake and no evidence of liver steatosis or fibrosis. However, slightly increased plasma liver markers may indicate a risk of future progression to more advanced stages of liver disease over time in some individuals. Several limitations should be considered when interpreting these data, including the potential misclassification of drinking categories and the lack of standardized cutoff scores for fatty liver as assessed by elastography, among others.

Predicting severe alcohol use disorders in primary care using number of heavy drinking days

BACKGROUND AND AIMS

Although screening for unhealthy alcohol use is becoming more common, severe alcohol use disorders (AUDs) associated with the most severe medical and socio-economic sequelae still often go unidentified in primary care. To improve identification of severe AUDs and aid clinical decision-making, we aimed to identify a threshold of heavy drinking days (HDDs) associated with severe AUDs.

DESIGN, SETTING AND CASES

This cohort study analyzed electronic health record data of 138 765 adults who reported ≥ 1 HDD (4+ drinks/occasion for women and men aged ≥ 65 years, 5+ for men aged 18-64 years) during a 3-month period at a routine alcohol screening in primary care in a large Northern California, USA health-care system from 2014 to 2017. Our sample was 66.5% male, 59.7% white, 11.0% Asian/Pacific Islander, 5.0% black, 17.4% Latino/Hispanic and 7.0% other/unknown race/ethnicity; the mean age was 40.6 years (standard deviation = 15.2).

MEASUREMENTS

We compared sensitivity and specificity of different thresholds of the reported number of HDDs during a 3-month period for predicting severe AUD diagnoses in the following year, in the full sample and by sex and age.

FINDINGS

The prevalence of severe AUD diagnoses in the year after the screening was 0.6%. The optimal threshold predicting future severe AUD diagnoses in the full sample was ≥ 5 HDDs during a 3-month period [sensitivity = 68.9%, 95% confidence interval (CI) = 65.9, 72.0; specificity = 63.2%, 95% CI = 62.9, 63.4], but varied by sex and age. Women had a lower threshold than men (4 versus 6 HDDs), which decreased as women aged (from 5 HDDs among 18-24 years to 4 HDDs ≥ 25 years), but increased as men aged (from 5 HDDs among 18-24 years to 6 HDDs among 25-64 years, to 7 HDDs ≥ 65 years).

CONCLUSIONS

Five or more heavy drinking days in a 3-month period may indicate heightened risk of future severe alcohol use disorder in an adult primary care population. The optimal thresholds are lower for women than for men, and thresholds decrease as women age but increase as men age.

Sex-specific association between alcohol consumption and liver cirrhosis: An updated systematic review and meta-analysis

Different studies have shown that females develop liver diseases at lower levels of alcohol consumption than males. Our aim was to quantify the dose-response relationship between alcohol consumption and the risk of liver cirrhosis by sex and identify the differences between females and males. A systematic review was conducted using PubMed/Medline and Embase to identify longitudinal and case-control studies that analyzed the relationship between the level of alcohol use and liver cirrhosis (LC) incidence, and mortality (ICD-8 and ICD-9 codes 571 and ICD-10 codes K70, K73, K74). Pooled relative risks (RR) were calculated by random effects models. Restricted cubic splines were used to model the dose-response relationship. A total of 24 studies were included in the analysis. There were collectively 2,112,476 females and 924,853 males, and a total of 4,301 and 4,231 cases of LC for females and males, respectively. We identified a non-linear dose-response relationship. Females showed a higher risk for LC compared to males with the same amount of alcohol consumed daily. For instance, drinking 40 g/day showed RRs of 9.35 (95% CI 7.64-11.45) in females and 2.82 (95% CI 2.53-3.14) in males, while drinking 80 g/day presented RRs of 23.32 (95% CI 18.24-29.82) in females and 7.93 (95% CI 7.12-8.83) in males. Additional analyses showed that a higher risk for females was found for morbidity and for mortality. Understanding the influence of sex on the association of alcohol consumption and the risk of LC is needed to develop recommendations and clinical guidelines for prevention and treatment.

The impact of an unemployment insurance reform on incidence rates of hospitalisation due to alcohol-related disorders: a quasi-experimental study of heterogeneous effects across ethnic background, educational level, employment status, and sex in Sweden

Background

Many Western countries have scaled back social and health expenditure, including decreases in the generosity and coverage of unemployment insurance, resulting in negative effects on general health and well-being at the aggregate level. Yet, research has not sufficiently looked into heterogeneity of such effects across different subgroups of the population. In Sweden, the 2006 unemployment insurance reform, implemented on the 1^st of January 2007, encompassed a drastic increase of insurance fund membership fees, reduced benefit levels, and stricter eligibility requirements. As this particularly affected already socioeconomically disadvantaged groups in society, such as foreign-born and low-educated individuals, the current study hypothesise that the reform would also have a greater impact on health outcomes in these groups.

Methods

Based on register data for the total population, we utilise a quasi-experimental approach to investigate heterogeneous health effects of the reform across ethnic background, educational level, employment status, and sex. Due to behaviourally caused diseases having a relatively shorter lag time from exposure, hospitalisation due to alcohol-related disorders serves as the health outcome. A series of regression discontinuity models are used to analyse monthly incidence rates of hospitalisation due to alcohol-related disorders among individuals aged 30–60 during the study period (2001–2012), with the threshold set to the 1^st of January 2007.

Results

The results suggest that, in general, there was no adverse effect of the reform on incidence rates of hospitalisation due to alcohol-related disorders. A significant increase is nonetheless detected among the unemployed, largely driven by Swedish-born individuals with Swedish-born or foreign-born parents, low-educated individuals, and men.

Conclusions

We conclude that the Swedish 2006 unemployment insurance reform generally resulted in increasing incidence rates of hospitalisation due to alcohol-related disorders among unemployed population subgroups known to have higher levels of alcohol consumption.

Alcohol Use during COVID-19 Pandemic: A Cross-Sectional Survey among Healthcare and Office Workers in Italy

BACKGROUND

The aim of our study of a sample of Italian healthcare (HCWs) and office workers (OWs) carried out during the pandemic period was to understand alcohol consumption patterns during the COVID-19 pandemic.

METHODS

A web-based cross-sectional survey based on Google Forms was developed. Harmful alcohol use was assessed through a validated questionnaire (AUDIT-C). Three multivariate logistic regression models were implemented for the overall sample of HCWs and OWs. The presence of harmful alcohol consumption (AUDIT-C score) was considered as a dependent variable.

RESULTS

A total of 1745 workers answered the survey. A lower risk of harmful drinking behavior among men overall and in both working groups was found (aOR 0.42, CI 95% 0.33-0.53), but also for both HCWs (aOR 0.62, CI 95% 0.46-0.84) and OWs (aOR 0.17, CI 95% 0.11-0.27). Comparing OWs and HCWs, we found a higher risk of harmful drinking in the first group (aOR 1.62, CI 95% 1.20-2.18).

CONCLUSIONS

The results of the survey indicate that unhealthy behaviors were elevated during the pandemic. It is urgent to implement company policies managed by an occupational doctor to raise workers' awareness of alcohol-related dangers and provide educational tools that have the task of preventing the damage caused by alcohol.

The critical impact of sex on preclinical alcohol research - Insights from zebrafish

Sex is an important biological variable that is widely recognized in studies of alcohol-related effects. Complementing clinical and preclinical rodent research, the zebrafish (Danio rerio) is the second most used laboratory species, and a powerful model organism in biomedicine. Like clinical and rodent models, zebrafish demonstrate overt sex differences in alcohol-related responses. Collectively, this evidence shows that the zebrafish becomes a sensitive model species to further probe in-depth sex differences commonly reported in alcohol research.

Alcohol Use

Unhealthy alcohol use-the consumption of alcohol at a level that has caused or has the potential to cause adverse physical, psychological, or social consequences-is common, underrecognized, and undertreated. For example, data from the 2020 National Survey on Drug Use and Health indicate that 7.0% of adults reported heavy alcohol use in the previous month, and only 4.2% of adults with alcohol use disorder received treatment. Primary care is an important setting for optimizing screening and treatment of unhealthy alcohol use to promote individual and public health.

Gender Differences in Alcohol Use: a Nationwide Study in a Multiethnic Population

The increase in alcohol consumption, and the greater consequences of chronic alcohol use among females, as well as the convergence of the gender gap warrants investigation. This paper aims to uncover gender differences in individuals with alcohol use disorder (AUD) in Singapore. The SMHS 2016 was a population-based, cross-sectional, epidemiological study. Recruitment spanned from August 2016 to March 2018, where 6126 respondents were recruited. Similarly to global estimates, lifetime prevalence and 12-month prevalence for AUD were higher in males than females. However, females had a higher prevalence of obsessive–compulsive disorder (OCD) co-morbidity than males. Women also had an earlier onset and age of recovery of AUD than men. Alarmingly, male (94.14%) and female (100%) respondents reported low help-seeking for their AUD. Gender differences in individuals with AUD were identified in Singapore population. Future research should direct its effort to identify barriers to help-seeking for individuals with alcohol use disorder.

The Role of Sex in Acute and Chronic Liver Damage

Acute and chronic hepatic damages are caused by xenobiotics or different diseases affecting the liver, characterized by different etiologies and pathological features. It has been demonstrated extensively that liver damage progresses differently in men and women, and some chronic liver diseases show a more favorable prognosis in women than in men. This review aims to update the most recent advances in the comprehension of the molecular basis of the sex difference observed in both acute and chronic liver damage. With this purpose, we report experimental studies on animal models and clinical observations investigating both acute liver failure, e.g., drug-induced liver injury (DILI), and chronic liver diseases, e.g., viral hepatitis, alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), autoimmune liver diseases, and hepatocellular carcinoma (HCC).

Sex-Related Differences in Voluntary Alcohol Intake and mRNA Coding for Synucleins in the Brain of Adult Rats Prenatally Exposed to Alcohol

Maternal alcohol consumption is one of the strong predictive factors of alcohol use and consequent abuse; however, investigations of sex differences in response to prenatal alcohol exposure (PAE) are limited. Here we compared the effects of PAE throughout gestation on alcohol preference, state anxiety and mRNA expression of presynaptic proteins α-, β- and γ-synucleins in the brain of adult (PND60) male and female Wistar rats. Total RNA was isolated from the hippocampus, midbrain and hypothalamus and mRNA levels were assessed with quantitative RT-PCR. Compared with naïve males, naïve female rats consumed more alcohol in “free choice” paradigm (10% ethanol vs. water). At the same time, PAE produced significant increase in alcohol consumption and preference in males but not in females compared to male and female naïve groups, correspondingly. We found significantly lower α-synuclein mRNA levels in the hippocampus and midbrain of females compared to males and significant decrease in α-synuclein mRNA in these brain areas in PAE males, but not in females compared to the same sex controls. These findings indicate that the impact of PAE on transcriptional regulation of synucleins may be sex-dependent, and in males’ disruption in α-synuclein mRNA expression may contribute to increased vulnerability to alcohol-associated behavior.

Growing alcohol use preceding death by suicide among women compared with men: age-specific temporal trends, 2003-18

BACKGROUND AND AIMS

In the United States, until 2018 both the prevalence of heavy alcohol use and the suicide mortality rate increased among men and women; however, women had experienced a notably higher increase in both. As heavy alcohol use may have contributed to the observed sex disparity in the suicide mortality rate increase, the aim of the current study was to estimate the temporal trend of the sex- and age-group-specific proportion of suicides that were alcohol-involved in the United States.

DESIGN

Using restricted-access data from the National Violent Death Reporting System, we performed joinpoint regression analyses to investigate temporal trends in the sex- and age-group (young adults = 18-34 years; middle-aged adults = 35-64 years; and older adults = 65+ years)-specific proportion of suicides that were alcohol-involved.

SETTING

United States.

PARTICIPANTS

A total of 115 202 suicide decedents 18+ years of age from 2003 to 2018.

MEASUREMENTS

The sex- and age-group-specific proportion of suicides that were alcohol-involved, among all suicide decedent, for which the decedent had a blood alcohol concentration (BAC) (a) ≥ 0.04 g/dl and (b) ≥ 0.08 g/dl.

FINDINGS

For 2003-18, the proportion of suicides that were alcohol-involved wherein the decedent had a BAC ≥ 0.08 g/day significantly increased on average annually for women of all age groups [young women: 2.80%, 95% confidence interval (CI) = 1.86%, 3.75%; middle-aged women: 2.20%, 95% CI = 1.20%, 3.21%; older women: 10.48%, 95% CI = 1.17%, 20.65%], while only middle-aged men experienced a significant average annual percentage increase (0.81%, 95% CI = 0.003%, 1.62%).

CONCLUSION

In the United States between 2003 and 2018, alcohol use preceding death by suicide increased among women compared with men.

What Predicts Willingness to Experience Negative Consequences in College Student Drinkers?

OBJECTIVE

Research has shown that students who were more willing to experience consequences reported higher rates of alcohol consumption and negative consequences. The present study used a longitudinal design to examine intra- and interpersonal consequence-specific predictors of willingness to experience negative consequences.

METHOD

Students (N = 2,024) were assessed in the fall (Time [T] 1) and spring (T2) semesters of their first year in college. Intrapersonal constructs (i.e., expectancies, subjective evaluations, self-efficacy), interpersonal constructs (i.e., peer descriptive, injunctive norms), and personality constructs (i.e., self-regulation, impulsivity, sensation seeking) were assessed at T1 and willingness to experience negative alcohol-related consequences was assessed 6 months later. A structural path model examined the relationship between T1 predictors and T2 willingness. T1 drinking and sex were included as covariates.

RESULTS

These results demonstrated significant positive relationships between T1 participants' subjective evaluations of consequences, expectancies of experiencing consequences, and T2 willingness to experience negative consequences. Further, impulsivity, sensation seeking, and T1 drinking showed significant, positive associations with willingness, whereas higher self-regulation was significantly associated with lower willingness. Men were significantly more willing to experience negative consequences than women. No significant associations were observed between normative perceptions and willingness.

CONCLUSIONS

Intrapersonal and personality constructs, as well as previous drinking, were significantly associated with willingness to experience consequences whereas interpersonal constructs were not. Men were significantly more willing to experience negative consequences. College student interventions may benefit from focusing on significant constructs identified in the current study (e.g., enhancing self-regulation) and focusing on students with higher willingness to experience negative consequences.

The indirect effect of negative emotionality via alcohol craving on abstinence self-efficacy among women in alcohol treatment

Women with alcohol use disorder (AUD) often present to treatment with heightened negative emotionality, including negative affect, anxiety, stress, and depression. Negative emotionality might impact women's alcohol abstinence self-efficacy (AASE), or confidence in their ability to remain sober, which is an important predictor of treatment outcomes. It is also plausible that other variables, such as alcohol craving, influence AASE. The present work examined the indirect effect of negative emotionality on AASE via alcohol craving as a mediator cross-sectionally among a sample of women enrolled in AUD treatment reporting co-occurring depressive symptoms (N = 73). Participants completed baseline measures of negative emotionality (e.g. anxiety and depression symptoms, stress, negative affect), alcohol craving, and AASE. All indices of negative emotionality were positively correlated with each other and alcohol craving (r's ranging from 0.244 to 0.671) and all but depression were inversely associated with AASE (r's ranging from -0.341 to -0.234; p <.05). In separate simple mediation models, we found that alcohol craving mediated the association of each of the four measures of negative emotionality with AASE. Further longitudinal and experimental work is necessary to determine if teaching skills to cope with alcohol craving in the context of co-occurring negative emotionality might lead to better therapeutic outcomes.

Alcohol-related consequences and the intention to seek care in treatment naïve women and men with severe alcohol use disorder

INTRODUCTION

Research on treatment utilization for alcohol use disorder (AUD) is based primarily on clinical samples and community samples of low AUD severity that may not need formal care. Using a community sample of adults with untreated but severe AUD symptoms, we tested the hypothesis that alcohol-related consequences, but not alcohol consumption levels, are associated with the intention to seek AUD treatment, examined associations of specific types of alcohol-related consequences with intention, and explored sex differences in these associations.

METHODS

The sample was recruited using social media ads for a randomized controlled trial to test a brief intervention to promote AUD treatment seeking. This report is based on analysis of baseline data collected prior to treatment intervention. Multiple linear regressions examined associations of measures of alcohol consumption, alcohol-related consequences broadly, and specific alcohol-related consequences with the intention to seek treatment. Moderating effects of sex on associations were explored.

RESULTS

Subjects (n = 349) averaged 41 years of age, 48% were female, 6% were Latinx, 80% were white, 15% were Black, and 92% met criteria for severe AUD. Alcohol consumption measures were not associated with intention to seek treatment whereas interpersonal- and intrapersonal- consequences were associated with intention. Sex served as a moderator, with intrapersonal consequences (e.g., sad mood) showing a stronger association with intention in women and social responsibility consequences (particularly financial) associated with intention in men.

CONCLUSION

Select alcohol-related consequences may be keys to understanding increased intention to seek AUD treatment including intrapersonal consequences in women and financial consequences in men.

Social Determinants of Health Associated With the Development of Sepsis in Adults: A Scoping Review

Evaluating risk for sepsis is complicated due to limited understanding of how social determinants of health (SDoH) influence the occurence of the disease. This scoping review aims to identify gaps and summarize the existing literature on SDoH and the development of sepsis in adults.

DATA SOURCES

A literature search using key terms related to sepsis and SDoH was conducted using Medline and PubMed.

STUDY SELECTION

Studies were screened by title and abstract and then full text in duplicate. Articles were eligible for inclusion if they: 1) evaluated at least one SDoH on the development of sepsis, 2) participants were 18 years or older, and 3) the studies were written in English between January 1970 and January 2022. Systematic reviews, meta-analyses, editorials, letters, commentaries, and studies with nonhuman participants were excluded.

DATA EXTRACTION

Data were extracted in duplicate using a standardized data extraction form. Studies were grouped into five categories according to the SDoH they evaluated (race, socioeconomic status [SES], old age and frailty, health behaviors, and social support). The study characteristics, key outcomes related to incidence of sepsis, mortality, and summary statements were included in tables.

DATA SYNTHESIS

The search identified 637 abstracts, 20 of which were included after full-text screening. Studies evaluating SES, old age, frailty, and gender demonstrated an association between sepsis incidence and the SDoH. Studies that examined race demonstrated conflicting conclusions as to whether Black or White patients were at increased risk of sepsis. Overall, a major limitation of this analysis was the methodological heterogeneity between studies.

CONCLUSIONS

There is evidence to suggest that SDoH impacts sepsis incidence, particularly SES, gender, old age, and frailty. Future prospective cohort studies that use standardized methods to collect SDoH data, particularly race-based data, are needed to inform public health efforts to reduce the incidence of sepsis and help clinicians identify the populations most at risk.

Patterns of alcohol consumption in Brazilian adults

In this study, we aimed to describe the patterns of alcohol consumption in Brazilian adults by sociodemographic characteristics and states according to sex. Cross-sectional study including 87,555 adults from the 2019 Brazilian National Health Survey who responded to a questionnaire on alcohol consumption and were classified as non-drinkers (0 g/day), light (1-12.5 g/day), moderate (12.6-49.9 g/day), and heavy drinkers (≥ 50 g/day). Of the Brazilian adults, 73.5% were non-drinkers. Among the drinkers, 14.8% were light drinkers. 82.6% of heavy drinkers were men. White participants drank more than non-white participants, except black women who were 38% more likely to be moderate drinkers than white women (ROR 1.38, 95% CI 1.09 to 1.76). Unmarried were more likely to be drinkers. Women over 55 and men over 65 years old were less likely to be drinkers. Compared to participants with none or incomplete primary education, both men and women with higher educational attainment were more likely to be light and moderate drinkers. The largest consumption of alcohol was found in Sergipe and Mato Grosso for men, and Mato Grosso do Sul and Bahia for women. Our findings may be useful to inform policies for reducing alcohol consumption in Brazil.

Adolescent Alcohol and Stress Exposure Rewires Key Cortical Neurocircuitry

Human adolescence is a period of development characterized by wide ranging emotions and behavioral risk taking, including binge drinking (Konrad et al., 2013). These behavioral manifestations of adolescence are complemented by growth in the neuroarchitecture of the brain, including synaptic pruning (Spear, 2013) and increases in overall white matter volume (Perrin et al., 2008). During this period of profound physiological maturation, the adolescent brain has a unique vulnerability to negative perturbations. Alcohol consumption and stress exposure, both of which are heightened during adolescence, can individually and synergistically alter these neurodevelopmental trajectories in positive and negative ways (conferring both resiliency and susceptibility) and influence already changing neurotransmitter systems and circuits. Importantly, the literature is rapidly changing and evolving in our understanding of basal sex differences in the brain, as well as the interaction between biological sex and life experiences. The animal literature provides the distinctive opportunity to explore sex-specific stress- and alcohol- induced changes in neurocircuits on a relatively rapid time scale. In addition, animal models allow for the investigation of individual neurons and signaling molecules otherwise inaccessible in the human brain. Here, we review the human and rodent literature with a focus on cortical development, neurotransmitters, peptides, and steroids, to characterize the field's current understanding of the interaction between adolescence, biological sex, and exposure to stress and alcohol.

Chronic Ethanol Causes Persistent Increases in Alzheimer's Tau Pathology in Female 3xTg-AD Mice: A Potential Role for Lysosomal Impairment

Epidemiological studies have found that heavy alcohol use is associated with increased risk for Alzheimer's disease (AD), with frequent drinking earlier in adulthood increasing risk. The increases in neuroinflammation featured in both heavy alcohol use and AD may be partially responsible for this link. However, it is unknown if abstinence mitigates this risk. We hypothesized that binge ethanol during mid adult life would persistently increase AD pathology even after prolonged abstinence. Male and female 3xTg-AD mice (APPSwe, tauP301, Psen1^tm1Mpm) which feature progressive amyloid (Aβ) and tau pathology, received chronic binge ethanol (5g/kg/day, 5-days-on/2-days-off, i.g.) or water during adulthood (from 5.5 to 9 months of age), followed by abstinence and assessment at 14 months of age. The effects of ethanol on protective AD genes (e.g., APOE and TREM2) as well as proinflammatory genes were measured by PCR. Levels of pathologic tau and Aβ were measured by immunohistochemistry and western blot. Ethanol caused persistent reductions in protective AD genes: APOE (25% reduction, *p < 0.05), TREM2 (28%, *p < 0.05), LPL (40%, ^** p < 0.01), and CTSD (24%, *p < 0.05) and promoted a proinflammatory gene signature in female, but not male cortex. Concurrently, ethanol increased total and hyperphosphorylated tau (AT8) in piriform cortex and hippocampus of females, but not males. Levels of AT8 were negatively correlated with APOE (R = -0.67, *p < 0.05) and TREM2 (R = -0.78, ^**p < 0.005) suggesting protective roles in pathogenesis. No differences were found in levels of main regulators of tau phosphorylation state (GSK3β, PKA, PP2A), suggesting ethanol disrupted clearance of tau. Therefore, we measured the effect of ethanol on lysosomes, which degrade tau, and lysosomal localization of tau using co-immunofluorescence. In females, ethanol caused a persistent reduction in mature LAMP1 lysosomes in CA1 of hippocampus (35%, *p < 0.05), along with a 60% increase in total tau (*p < 0.05). Thus, chronic binge ethanol during mid adult life causes a persistent enhancement of tau pathology in cortical and hippocampal brain regions of females. Persistent AD pathology was associated with an increased proinflammatory signature and a reduction of mature lysosomes. This implicates binge ethanol exposure with increased risk of AD pathologic progression in females.

Chronic Intermittent Ethanol Administration during Adolescence Produces Sex Dependent Impairments in Behavioral Flexibility and Survivability

Chronic intermittent ethanol exposure during adolescence produces behavioral impairments and neurobiological changes that can last into young adulthood. One such behavioral impairment is reduced behavioral flexibility, a behavioral impairment that has been correlated with the risk for increased ethanol intake. In the current study, we investigated if chronic intermittent ethanol exposure during adolescence alters cognition, including behavioral flexibility, over a 22-month testing period. Female and male rats were treated with either 3.0 g/kg or 5.0 g/kg ethanol via gavage in a chronic intermittent fashion during adolescence and then tested every 4 to 5 months on a series of cognitive measures in the Morris water maze. Chronic intermittent ethanol selectively impaired behavioral flexibility in both female and male rats, although the pattern of results was different as a function of sex. In addition, female, but not male, rats were impaired in a short-term relearning test. Finally, male rats administered ethanol during adolescence were significantly more likely to not survive the 22-month experiment compared to female rats administered ethanol during adolescence. The current results demonstrate that adolescence is a unique period of development where chronic intermittent ethanol exposure produces long-lasting, selective cognitive impairments across the lifespan.

Sex-related differences in pattern of ethanol drinking under the intermittent-access model and its impact on exploratory and anxiety-like behavior in Long-Evans rats

BACKGROUND

While men in the United States consume more alcohol than women, rates of drinking are converging. Nevertheless, females remain underrepresented in preclinical alcohol research. Here, we examined rats' sex-related differences in patterns of ethanol (EtOH) drinking and the effects of this drinking on exploratory and anxiety-like behavior.

METHODS

Adult male and female Long-Evans rats were given 20% ethanol under the intermittent-access two-bottle-choice paradigm. Their intake was measured daily for the first 7 weeks. During the eighth week, intake was measured over the 24 h of daily access. During the ninth week, they, along with EtOH-naive controls, were tested prior to daily access in a novel chamber, light-dark box, and hole board apparatus. During the tenth week, blood ethanol concentration (BEC) was assessed after 30 to 40 min of access.

RESULTS

Females overall demonstrated higher ethanol intake and preference across all access weeks than males, although only half of females drank significantly more than males. Across 24 h of daily access, both sexes had their highest intake in the first 30 min and their lowest in the middle of the light phase of the light/dark cycle. Despite their greater ethanol intake, females did not show significantly different BECs than males. In behavioral tests, females showed less vertical time in a novel activity chamber, more movement between chambers in a light-dark box, and more nose pokes in a hole-board apparatus than males. While a history of ethanol drinking led to a trend for lower vertical time in the activity chamber and greater chamber entries in the light-dark box, the effects were not sex-dependent.

CONCLUSIONS

These results suggest that female and male rats could both be tested for acute effects of ethanol after 30 min of daily access, but that nuanced considerations are needed in the design of these experiments and the interpretation of their findings.
