Changes in alcohol use during COVID-19 and associations with contextual and individual difference variables: A systematic review and meta-analysis

Research trends and hotspot analysis of age-related hearing loss: A bibliometric analysis from 2019 to 2023

BACKGROUND

Age-related hearing loss (ARHL) - also termed presbycusis - is prevalent among older adults, leading to a range of issues. Although considerable progress in the understanding of ARHL over the decades, available reports lack data from recent years and do not comprehensively reflect the latest advancements and trends. Therefore, our study sought to assess research hotspots and trends in ARHL over the past 5 years to provide the basis for future research.

MATERIALS AND METHODS

The Web of Science Core Collection database was searched and screened from January 1, 2019 to October 21, 2023, according to the inclusion criteria. CiteSpace (5.8.R3), VOSviewer (1.6.19), and Microsoft Excel 2019 were employed for bibliometric analysis and visualization.

RESULTS

3084 articles from 92 countries led by the United States and China were included. There has been a steady upward trend in the number of publications from 2019 to 2023. The most productive institutions, authors, and journals are Johns Hopkins University (n = 113), Lin FR (n = 66), and Ear and Hearing (n = 135), respectively. Trend topic analyses revealed that "cochlear synaptopathy" and "dementia" were the predominant foci. Keywords, including "individuals" and "national health", began to appear.

CONCLUSION

Over the past 5 years, the annual number of publications has increased significantly and will continue to do so. Research on the mechanism of ARHL, represented by "oxidative stress", is a continuing focus. Emerging topics such as "individual differences" and "national health" may be potential future hotspots in this field.

Parental Patterns of Alcohol Consumption During the COVID-19 Pandemic: Scoping Review

BACKGROUND

The declaration of the COVID-19 pandemic led to public health restrictions that impacted the lives of people across the globe. Parents were particularly burdened with balancing multiple responsibilities, such as working from home while caring for and educating their children. Alcohol use among parents is an area that warrants further exploration.

OBJECTIVE

This study aimed to investigate patterns of parental alcohol consumption during the COVID-19 pandemic, focusing on relative changes in the frequency and quantity of alcohol use compared to prepandemic use, nonparent adult samples, or both.

METHODS

A scoping review informed by the methodology of Arksey and O'Malley explored patterns of parental alcohol consumption during the COVID-19 pandemic. Searches were conducted in CINAHL, Ovid MEDLINE, PsycINFO, and Web of Science. Search terms were created using the Joanna Briggs Institute framework of Population, Concept, and Context, with the population being parents and the concept being alcohol consumption during the COVID-19 pandemic.

RESULTS

The database search yielded 3568 articles, which were screened for eligibility. Of the 3568 articles, 40 (1.12%) met the inclusion criteria and were included in the scoping review. Findings indicated the following: (1) having children at home was a factor associated with parental patterns of alcohol use; (2) mixed findings regarding gender-related patterns of alcohol consumption; and (3) linkages between parental patterns of alcohol use and mental health symptoms of stress, depression, and anxiety.

CONCLUSIONS

This scoping review revealed heterogeneous patterns in parental alcohol use across sociocultural contexts during the COVID-19 pandemic. Given the known harms of alcohol use, it is worthwhile for clinicians to assess parental drinking patterns and initiate conversations regarding moderation in alcohol use.

The impact of COVID-19-related national lockdowns on alcohol-related traffic collisions, injuries, and fatalities in Lithuania

BACKGROUND

The national lockdowns that occurred all over the world in response to the Coronavirus Disease 2019 (COVID-19) pandemic have been found to have impacted alcohol use. The aim was to evaluate the impact of COVID-19-related national lockdowns on alcohol-related traffic collisions, injuries, and fatalities in Lithuania.

METHODS

Using monthly data from the Lithuanian Road Police Service for January 2004 to December 2022, we performed interrupted time-series analyses using a generalized additive model to evaluate the impact of COVID-19-related national lockdowns on alcohol-related traffic collisions, injuries, and fatalities. In Lithuania, the COVID-19-related lockdowns occurred from March 2020 to June 2020 and from November 2020 to June 2021.

RESULTS

Although overall rates for traffic collisions and injuries decreased during the COVID-19-related lockdowns in Lithuania, these lockdowns were associated with a 3.21% (95% CI: 1.19%, 5.23%) increase in the relative proportion of alcohol-related traffic collisions and a 2.46% (95% CI: 0.12%, 4.80%) increase in the relative proportion of alcohol-related traffic injuries. The association between the lockdowns and alcohol-related traffic fatalities was not statistically significant.

CONCLUSION

The COVID-19-related national lockdowns in Lithuania were associated with a decrease in the overall rate of traffic collisions and injuries, but an increase in the relative proportion of alcohol-related traffic collisions and injuries.

Investigating Substance Use as a Coping Strategy Among Adolescent Psychiatric Inpatients: A Comparative Analysis Before and During the COVID-19 Pandemic

The COVID-19 pandemic resulted in significant changes in daily life, potentially impacting mental health and substance use behavior. Research on COVID-related changes in adolescent substance use have yielded mixed findings. The current cross-sectional chart review study compared rates of past-year substance use before and during COVID-19 among adolescent psychiatric inpatients, and investigated how motives for coping with COVID-19 changes were related to psychiatric acuity, and past-year substance use. Count models assessed if the number of past-year days of alcohol and cannabis use was higher among adolescents (n = 491, 11-18 years, 61% female) hospitalized during COVID-19 (3/14/20 to 4/5/21) versus adolescents hospitalized before COVID-19 (8/30/2019 to 3/13/20). For a subsample of COVID-19 inpatients (n = 124; 75% female), we evaluated psychiatric correlates of endorsing substances to cope with COVID-19 changes/rules. Results indicated adolescents admitted during COVID-19 reported significantly more past-year alcohol and cannabis use days than adolescents admitted before COVID-19. Adolescents endorsed using alcohol (19%), cannabis (33%), and e-cigarettes/vaping (25%) to cope with COVID-19. E-cigarette/vaping to cope with COVID-19 was significantly related to lifetime suicide attempt. Endorsing alcohol or cannabis to cope with COVID-19 was associated with a significantly greater number of past-year use days for each respective substance. Adolescent psychiatric inpatients admitted during COVID-19 reported more substance use days than adolescents admitted before COVID-19. Using substances to cope was linked to psychiatric correlates (e.g., suicidality). Assessing the presence and function of substance use in this population may be important to identify, treat, and prevent compounding negative outcomes during times of community stress.

The ReCoDe addiction research consortium: Losing and regaining control over drug intake-Findings and future perspectives

Substance use disorders (SUDs) are seen as a continuum ranging from goal-directed and hedonic drug use to loss of control over drug intake with aversive consequences for mental and physical health and social functioning. The main goals of our interdisciplinary German collaborative research centre on Losing and Regaining Control over Drug Intake (ReCoDe) are (i) to study triggers (drug cues, stressors, drug priming) and modifying factors (age, gender, physical activity, cognitive functions, childhood adversity, social factors, such as loneliness and social contact/interaction) that longitudinally modulate the trajectories of losing and regaining control over drug consumption under real-life conditions. (ii) To study underlying behavioural, cognitive and neurobiological mechanisms of disease trajectories and drug-related behaviours and (iii) to provide non-invasive mechanism-based interventions. These goals are achieved by: (A) using innovative mHealth (mobile health) tools to longitudinally monitor the effects of triggers and modifying factors on drug consumption patterns in real life in a cohort of 900 patients with alcohol use disorder. This approach will be complemented by animal models of addiction with 24/7 automated behavioural monitoring across an entire disease trajectory; i.e. from a naïve state to a drug-taking state to an addiction or resilience-like state. (B) The identification and, if applicable, computational modelling of key molecular, neurobiological and psychological mechanisms (e.g., reduced cognitive flexibility) mediating the effects of such triggers and modifying factors on disease trajectories. (C) Developing and testing non-invasive interventions (e.g., Just-In-Time-Adaptive-Interventions (JITAIs), various non-invasive brain stimulations (NIBS), individualized physical activity) that specifically target the underlying mechanisms for regaining control over drug intake. Here, we will report on the most important results of the first funding period and outline our future research strategy.

Trends in purchasing cross-border, illicit and home-brewed alcohol: A population study in Great Britain, 2020-2023

INTRODUCTION

The last 3 years have seen substantial changes in Great Britain (GB) including the COVID-19 pandemic, cost-of-living crisis and policy changes such as minimum unit pricing. We examined changes in purchasing cross-border, illicit and home-brewed alcohol among risky drinkers over this period.

METHODS

Data were used from 22,086 adult (≥18 years) increasing/higher-risk drinkers (AUDIT-C ≥5) participating in a monthly cross-sectional survey between October 2020 and August 2023. We estimated time trends in the proportion reporting obtaining alcohol from: (i) cross-border (any/within-GB/international); (ii) illicit; and (iii) home-brewed sources in the past 6 months.

RESULTS

Between October 2020 and August 2023, the proportion reporting cross-border alcohol purchases increased (from 8.5% to 12.5% overall; prevalence ratio [PR] = 1.47 [95% CI 1.17-1.86]). This was largely driven by an increase in cross-border purchases abroad (PR = 1.52 [1.13-2.05]), with a smaller, uncertain increase in cross-border purchases within GB (PR = 1.37 [0.96-1.95]). The prevalence of cross-border alcohol purchasing was higher in Wales (13.8% [12.3-15.4%]) and Scotland (6.1% [5.4-6.8%]) than England (3.6% [3.3-3.9%]). There was little change in illicit alcohol purchasing in England or Wales (4.1% [3.7-4.4%]; 4.2% [3.2-5.1%]), but in Scotland it fell from 5.7% to 2.4% (PR = 0.42 [0.19-0.81]). Home-brewed alcohol was rare (GB: 3.1% [2.9-3.4]) and stable.

DISCUSSION AND CONCLUSIONS

The proportion of increasing/higher-risk drinkers in GB purchasing cross-border alcohol increased between October 2020 and August 2023, due to an increase in people buying alcohol abroad. Cross-border alcohol purchases within GB were more commonly reported in Wales and Scotland. The small proportion purchasing illicit alcohol did not change substantially in England or Wales, but fell by half in Scotland.

Reducing alcohol harms whilst minimising impact on hospitality businesses: 'Sweetspot' policy options

BACKGROUND

During COVID-19, hospitality businesses (e.g. bars, restaurants) were closed/restricted whilst off-sales of alcohol increased, with health consequences. Post-covid, governments face lobbying to support such businesses, but many health services remain under pressure. We appraised 'sweetspot' policy options: those with potential to benefit public services and health, whilst avoiding or minimising negative impact on the hospitality sector.

METHODS

We conducted rapid non-systematic evidence reviews using index papers, citation searches and team knowledge to summarise the literature relating to four possible 'sweetspot' policy areas: pricing interventions (9 systematic reviews (SR); 14 papers/reports); regulation of online sales (1 SR; 1 paper); place-shaping (2 SRs; 18 papers/reports); and violence reduction initiatives (9 SRs; 24 papers/reports); and led two expert workshops (n = 11).

RESULTS

Interventions that raise the price of cheaper shop-bought alcohol appear promising as 'sweetspot' policies; any impact on hospitality is likely small and potentially positive. Restrictions on online sales such as speed or timing of delivery may reduce harm and diversion of consumption from on-trade to home settings. Place-shaping is not well-supported by evidence and experts were sceptical. Reduced late-night trading hours likely reduce violence; evidence of impact on hospitality is scant. Other violence reduction initiatives may modestly reduce harms whilst supporting hospitality, but require resources to deliver multiple measures simultaneously in partnership.

CONCLUSIONS

Available evidence and expert views point to regulation of pricing and online sales as having greatest potential as 'sweetspot' alcohol policies, reducing alcohol harm whilst minimising negative impact on hospitality businesses.

Risk of mortality among patients with alcohol-associated hepatitis in the US from 2007 to 2021

BACKGROUND/AIMS

Alcohol-associated hepatitis (AH) mortality and risk factors have not been carefully studied in real-world settings. We examined the rate, temporal trend, and risk factors of mortality in AH.

METHODS

We conducted a cohort study of individuals with AH diagnoses using medical claims data from Optum's Clinformatics® Data Mart (CDM). Participants were individuals covered by Medicare Advantage and commercial insurance policies. Cases were identified using diagnostic codes. Cox regressions were used to estimate 90 and 180-day mortality rates by hospitalization status.

RESULTS

The cohort included 32,001 patients (72% men) who had at least one year of continuous insurance coverage prior to AH diagnoses. Of these, 20,912 were hospitalized within seven days of diagnosis. Ninety and 180-day mortality rates were 12.0% (95% CI [11.6%, 12.5%]) and 16.0% (95% CI [15.4%, 16.5%]), respectively, for the hospitalized patients and 3.1% (95% CI [2.8%, 3.4%]) and 5.1% (95% CI [4.6%, 5.5%]) for the non-hospitalized patients. Pre-existing liver disease, even in a mild form, was associated with an increased risk of death. In hospitalized patients, a history of mild liver disease was associated with a 24% increase in 180-day mortality risk (HR = 1.24, 95% CI: [1.14, 1.36]). Moderate-to-severe liver disease was associated with a more than doubled risk (HR = 2.33, 95% CI: [2.12, 2.56]).

CONCLUSIONS

History of liver disease was associated with significantly increased AH mortality. The finding highlights the chronic disease context of AH and suggests that prior diagnosis of liver disease should be considered for prognosis and targeted prevention.

Analysis of the BDNF Gene rs6265 Polymorphism in a Group of Women with Alcohol Use Disorder, Taking into Account Personality Traits

It seems that BDNF has a direct influence on the brain pathways and is typically engaged during the processing of rewards. A surge in BDNF levels in the ventral tegmental area (the region from which the dopaminergic neurons of the mesocorticolimbic dopamine system originate and extend to the dorsolateral and ventromedial striatum) triggers a state of reward similar to that produced by opiates in animal studies. The aims of the study were (1) to analyze the association of the BDNF gene rs6265 polymorphism with AUD (alcohol use disorder) in women, (2) analyze personality and anxiety in alcohol-dependent and control woman, and (3) conduct an interaction analysis of rs6265 on personality, anxiety, and alcohol dependence. Our study found a notable interaction between the anxiety (trait and state), neuroticism, rs6265, and AUD. The alcohol AUD G/A genotype carriers revealed higher level of the anxiety trait (p < 0.0001) and neuroticism (p < 0.0001) compared to the control group with G/A and G/G genotypes. The alcohol use disorder subjects with the G/A genotype displayed higher levels of an anxiety state than the control group with G/A (p < 0.0001) and G/G (p = 0.0014) genotypes. Additionally, the alcohol use disorder subjects with the G/G genotype obtained lower levels of agreeability compared to the controls with G/A (p < 0.0001) and G/G (p < 0.0001) genotypes. Our study indicates that anxiety (trait and state) and neuroticism are interacting with the BDNF gene rs6265 polymorphism in alcohol-dependent women. Characteristics like anxiety (both as a trait and a state) and neuroticism could have a significant impact on the mechanism of substance dependency, particularly in females who are genetically susceptible. This is regardless of the reward system that is implicated in the emotional disruptions accompanying anxiety and depression.

The impact of COVID-19 on the clinical course and outcome of patients with cirrhosis: An observational study

Background and Aims

Severe outcomes of COVID-19 are associated with advancing age and comorbidities. The specific aim of our study was to determine the impact of COVID-19 on the clinical course and outcome of patients with cirrhosis.

Methods

We retrieved data from VA national repository and identified patients tested for SARS-CoV-2 RNA who had cirrhosis. Each virus positive patient was propensity-matched with virus negative subjects by demographics and comorbidities. Primary endpoint was death within 30 days of COVID-19 diagnosis and secondary endpoint was hospitalization within 14 days.

Results

Among 1,115,037 individuals tested for SARS-CoV-2 RNA, 31,680 had cirrhosis. Of those patients, 4456 virus positive patients were propensity-matched with 8752 virus negative subjects. In this cohort of 13,208, median age was 67 years and 95% were male. Most had multiple comorbidities. Alcohol use, hepatitis C and MASH were the dominant etiologies of cirrhosis. At baseline, median MELD was 6% and 21% had hepatic decompensation. Advanced age was the most significant determinant of hospitalization and mortality. Comorbidities, alcohol use and MELD increased the likelihood of hospitalization whereas SARS-CoV-2 positivity had lower Day-14 hospitalization hazard. MELD was associated with higher mortality hazard whereas vaccination reduced the hazard of hospitalization and death. SARS-CoV-2 positivity increased the hazard of death at Day-30 by 72% and at Day-90 by 26%.

Conclusion

Although patients with cirrhosis who developed COVID-19 were less likely to be hospitalized, they were more likely to die within 30 days compared to their virus negative counterparts. Vaccination was effective in reducing both hospitalization and death.

The impact of the COVID-19 pandemic on dietary behaviors among school-age children, adolescents, and young adults: a systematic review and meta-analysis

CONTEXT

The COVID-19 pandemic has had a global impact on food security and nutrition, both in the short and long term. The influence on school-age children, adolescents, and young adults may be particularly significant and long-lasting.

OBJECTIVE

This systematic review and meta-analysis aimed to quantify the impact of the COVID-19 pandemic on dietary habits among school-age children, adolescents, and young adults worldwide.

DATA SOURCES

PubMed, Web of Science, and Embase were searched from inception to October 5, 2023.

DATA EXTRACTION

We included observational studies published in English that reported dietary quality scores and dietary intake quantities during and before the COVID-19 pandemic among school-age children, adolescents, and young adults. We included a total of 22 cohort studies and 20 cross-sectional studies of high or moderate quality.

DATA ANALYSIS

We conducted a meta-analysis, expressing dietary quality scores and dietary intake quantities as standardized mean differences (SMD) with 95% confidence intervals (CIs). For studies with low heterogeneity, we used a fixed-effects model; otherwise, we applied a random-effects model. The Newcastle-Ottawa Scale was employed by 2 reviewers independently to evaluate methodological quality. The analysis indicated that, overall, juice intake increased (SMD = 0.12, 95% CI: 0.04 to 0.20), while alcohol consumption reduced during the COVID-19 pandemic (SMD = -0.28, 95% CI: -0.47 to -0.08). However, the age-stratified results varied. Among school-age children, intake of fruit, dairy products, sugar, and juice increased. Adolescents showed an increase in meal frequency and vegetable intake. Young adults showed reduced carbohydrate and alcohol intakes, while protein and dairy product intakes increased, based on limited included studies.

CONCLUSION

Dietary changes in school-age children from before to during the pandemic were mixed, while dietary behavior changes in adolescents and young adults tended to be more positive. Considering the lasting effects of negative dietary behaviors, attention should be given to addressing the increased sugar and juice intakes. It is also crucial that caregivers and researchers monitor whether positive dietary behaviors will rebound after returning to normal study and life.

Modelling the longer-term health and health inequality impacts of changes in alcohol consumption during the COVID-19 pandemic in England

BACKGROUND

Alcohol consumption changed substantially during the COVID-19 pandemic for many people. This study quantified how these changes in drinking varied across the population and their potential longer-term impact on health and health inequalities.

METHODS

We analyzed data from the Alcohol Toolkit Study to estimate how alcohol consumption changed during the pandemic (April 2020-November 2021) and how these changes varied with age, sex, drinking level and socioeconomic position. We combined these estimates with a range of alternative scenarios of future alcohol consumption and used the Sheffield Alcohol Policy Model to assess the long-term health and health inequality impacts of these changes.

RESULTS

Alcohol consumption in 2020-21 increased in heavier drinkers but fell in moderate drinkers. If alcohol consumption returns to pre-pandemic levels in 2022, we estimate a total of 42 677 additional hospital admissions and 1830 deaths over 20 years because of these changes. If consumption remains at 2021 levels in the long-term these figures rise to 355 832 and 12 849, respectively. In all scenarios, the biggest increase in harm occurs in the most deprived 20% of the population.

CONCLUSIONS

Pandemic-era changes in alcohol consumption are likely to have a significant negative impact on public health and health inequalities, even under optimistic assumptions about future drinking.

A novel mouse home cage lickometer system reveals sex- and housing-based influences on alcohol drinking

Alcohol use disorder (AUD) is a significant global health issue. Despite historically higher rates among men, AUD prevalence and negative alcohol-related outcomes in women are rising. Loneliness in humans has been associated with increased alcohol use, and traditional rodent drinking models involve single housing, presenting challenges for studying social enrichment. We developed LIQ PARTI (Lick Instance Quantifier with Poly-Animal RFID Tracking Integration), an open-source tool to examine home cage continuous access two-bottle choice drinking behavior in a group-housed setting, investigating the influence of sex and social isolation on ethanol consumption and bout microstructure in C57Bl/6J mice. LIQ PARTI, based on our previously developed single-housed LIQ HD system, accurately tracks drinking behavior using capacitive-based sensors and RFID technology. Group-housed female mice exhibited higher ethanol preference than males, while males displayed a unique undulating pattern of ethanol preference linked to cage changes, suggesting a potential stress-related response. Chronic ethanol intake distinctly altered bout microstructure between male and female mice, highlighting sex and social environmental influences on drinking behavior. Social isolation with the LIQ HD system amplified fluid intake and ethanol preference in both sexes, accompanied by sex- and fluid-dependent changes in bout microstructure. However, these effects largely reversed upon resocialization, indicating the plasticity of these behaviors in response to social context. Utilizing a novel group-housed home cage lickometer device, our findings illustrate the critical interplay of sex and housing conditions in voluntary alcohol drinking behaviors in C57Bl/6J mice, facilitating nuanced insights into the potential contributions to AUD etiology.

Changes in substance use, recovery, and quality of life during the initial phase of the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic disrupted lives on a massive scale. While the pandemic appeared to worsen mental health outcomes broadly, its effects on alcohol/substance use and recovery are unclear. Many studies convolved the sociopolitical unrest beginning in May 2020 with the pandemic. We assessed pandemic-related changes in substance use, recovery involvement, and quality of life among US adults at two specified time periods that isolated pandemic effects from potentially confounding sociopolitical factors.

OBJECTIVES

We tested the following hypotheses: the pandemic and consequent policies (1) increased use of alcohol and illicit substances in active users; (2) increased use of alcohol/substances among people in early recovery; (3) reduced participation in recovery activities among those in early recovery, and that (4) use amount and use events correlated with impulsivity in both groups and that (5) substance use and abstinence correlated with resilience.

METHODS

We recruited 1,685 participants through Amazon's Mechanical Turk (MTurk). We assessed demographics, quality of life, alcohol/substance use, recovery activities, and measures of impulsivity and resilience at two time points, pre-pandemic and (early) during-pandemic. Only n = 45 (Active Users; males n = 32) and n = 34 (Recovery; males n = 20) passed data quality checks and were included in the primary analyses.

RESULTS

Among Active Users, weekly alcohol consumption and days spent using alcohol and illicit substances decreased during the pandemic. Resilience negatively correlated with pandemic-related substance use in early recovering participants. Significant reduction in the quality of life was coincident with a trend of lower recovery activity participation (31% decline) during the pandemic.

CONCLUSIONS

The reduced alcohol/substance use and participation in recovery activities might be expected from conditions that promote social isolation. The high prevalence of low-quality data from MTurk cautions for careful use of online data sourcing.

Factors associated with very high-risk drinking in the Australian general population: How do men and women compare?

INTRODUCTION

Despite vulnerability to alcohol-related harms, women have historically been under-represented in alcohol research. This study examined the prevalence and characteristics of women who drink at very high-risk levels (11+ standard drinks monthly), factors associated with this consumption and comparisons with men.

METHODS

Secondary analyses of 2019 National Drug Strategy Household Survey data were undertaken. Significant differences by sex in the distribution of demographic and alcohol-related variables were explored using chi-squared and Mann-Whitney U tests. Binary logistic regression examined factors associated with very high-risk drinking.

RESULTS

Very high-risk drinking was reported by 10.4% of men and 3.1% of women. Compared to men, women were significantly younger with higher levels of psychological distress/mental health conditions, and were more likely to be unmarried. Both women and men engaged in a range of harm-minimisation strategies. Odds of very high-risk drinking were significantly higher for respondents who were male, younger, employed, lived in a regional/rural/remote area, psychologically distressed, smoked and used illicit drugs. Interactions with sex indicated that very high-risk drinking declined after the age of 24 for men compared to 44 for women. Being married reduced the likelihood of very high-risk drinking more greatly among women compared to men, while living in a major city reduced the likelihood among men (and not women).

DISCUSSION AND CONCLUSIONS

Very high-risk drinking is not limited to Australian men, and the women who drink at these levels have distinct profiles and factors associated with consumption.

Drinking While Stressed and Drinking to Cope Differentially Relate to Mental Health

Excessive alcohol use, as well as drinking to manage distress, are known to undermine mental health. The current study examined the unique associations of simply consuming alcohol while stressed, versus using alcohol to cope with distress, with mental health during the early stages of COVID-19. Participants (N = 264) reported their alcohol use and use of alcohol/substances to cope with stress daily for 22 days and completed measures of mental health at baseline and every 7 days thereafter. Hierarchical regression models were tested to predict drinking while stressed, drinking to cope, and mental health. At baseline, drinking while stressed was not significantly associated with mental health when coping motives were accounted for. However, drinking to cope was significantly associated with greater stress, anxiety, depression, and loneliness. Drinking while stressed was significantly predicted by baseline stress and loneliness, while drinking to cope was significantly predicted by baseline anxiety. Drinking while stressed was not a significant predictor of change in mental health when coping motives were accounted for. Drinking to cope was a significant predictor of increases in depression but not of change in stress, anxiety, or loneliness. The motivation to manage distress appears to be driving the negative effects of alcohol use on mental health.

Changes in alcohol consumption and binge drinking during the COVID-19 pandemic among American Indians residing in California and Oklahoma

Background: This study explored the increased quantity and frequency of alcohol use in the American Indian (AI) population during the COVID-19 pandemic.Objectives: The aims of this study were to explore possible associations between covariables and both binge drinking and alcohol consumption during COVID-19.Methods: This cross-sectional survey study analyzed data from a sample of AI individuals (63% female) residing in California (n = 411) and Oklahoma (n = 657) between October 2020-January 2021. Analysis included summary statistics and multivariable logistic regression, including a variety of socio-economic, COVID-19 concern, and tobacco and marijuana use variables.Results: One or more alcohol binge episodes were reported between October 2020-January 2021 in 19.3% of participants and elevated overall alcohol consumption was reported by 21.6% of participants. Higher odds of elevated alcohol consumption occurred in women and those following more social distancing measures. The odds of binge drinking or elevated alcohol consumption in those using both marijuana and tobacco (aOR/ adjusted odds ratio:18.9, 95% CI = 8.5, 42.2, and aOR:3.9, 95% CI = 1.7, 8.6, respectively) were higher compared to those using neither. Similarly, the odds of binge drinking or elevated alcohol consumption in those using tobacco only (aOR:4.7, 95% CI = 2.9, 7.7 and aOR: 2.0, 95% CI = 1.1, 3.5, respectively) were higher compared to those using neither.Conclusions: This study found high rates of alcohol use and bingeing during the COVID-19 pandemic. Offering collaborative, culturally sensitive, and affordable support services are important components of intervention and preparation for future stressful events on local, as well as global levels.

The role of brain serotonin signaling in excessive alcohol consumption and withdrawal: A call for more research in females

Alcohol Use Disorder (AUD) is a leading cause of death and disability worldwide, but current treatments are insufficient in fully addressing the symptoms that often lead to relapses in alcohol consumption. The brain's serotonin system has been implicated in AUD for decades and is a major regulator of stress-related behaviors associated with increased alcohol consumption. This review will discuss the current literature on the association between neurobiological adaptations in serotonin systems and AUD in humans as well as the effectiveness of serotonin receptor manipulations on alcohol-related behaviors like consumption and withdrawal. We will further discuss how these findings in humans relate to findings in animal models, including a comparison of systemic pharmacological manipulations modulating alcohol consumption. We next provide a detailed overview of brain region-specific roles for serotonin and serotonin receptor signaling in alcohol-related behaviors in preclinical animal models, highlighting the complexity of forming a cohesive model of serotonin function in AUD and providing possible avenues for more effective therapeutic intervention. Throughout the review, we discuss what is known about sex differences in the sequelae of AUD and the role of serotonin in these sequelae. We stress a critical need for additional studies in women and female animals so that we may build a clearer path to elucidating sex-specific serotonergic mechanisms and develop better treatments.

Sex and gender in alcohol use disorder and alcohol-associated liver disease in the United States: A narrative review

Over the last 20 years, there has been an alarming increase in alcohol use and AUD prevalence among women, narrowing the historical gender gap. Concurrently, there has also been a significant rise in alcohol-associated liver disease (ALD) prevalence, severity, and mortality among women. Despite this, there are no recent reviews that have sought to evaluate both sex and gender differences at the intersection of AUD and ALD. In this narrative review, we address the escalating rates of ALD and AUD in the United States, with a specific focus on the disproportionate impact on women. Sex and gender play an important and well-known role in the pathogenesis and epidemiology of ALD. However, sex and gender are also implicated in the development and prevalence of AUD, as well as in the treatment of AUD, all of which have important consequences on the approach to the treatment of patients with ALD and AUD. A better understanding of sex and gender differences in AUD, ALD, and the intersection of the 2 is essential to enhance prevention, diagnosis, and management strategies. These data underscore the urgent need for awareness and preventive efforts to mitigate the potential long-term health consequences.

Alcohol-associated liver disease-Global epidemiology

Alcohol-associated liver disease (ALD), as highlighted in this narrative review, is a major public health concern, increasingly impacting global disease burden and premature mortality. In 2019, ALD accounted for the loss of 11 million life-years worldwide. The rising number of deaths and disability-adjusted life-years attributed to ALD, particularly pronounced in the United States, are alarming. Projections suggest that the economic impact of ALD, as seen in the United States, could potentially double by 2040. ALD is increasingly prevalent among younger adults (20-45 y) and has become the leading cause of liver transplantation in both United States and Europe. During the COVID-19 pandemic, the existing trend was further amplified as high-risk drinking patterns coincided with a rise in hospital admissions for alcohol-associated hepatitis and increased ALD-related mortality. The prevalence of ALD is estimated at 3.5% in the general population, 26.0% among hazardous drinkers, and 55.1% among those with alcohol use disorders. Alarmingly, 5-year mortality rates for patients with ALD exceed 50%, with even higher rates in more advanced disease stages. Methodological challenges, such as underreporting, diagnostic difficulties, and variability in registry data quality, complicate the accurate assessment of the impact of ALD. Additionally, the contribution of alcohol to the progression of other liver diseases is often under acknowledged in health care registries, leading to a significant underestimation of its broader implications for liver health. Addressing the growing ALD concern requires robust public health initiatives, heightened awareness, refined diagnostic techniques, and comprehensive epidemiological studies. These measures are vital to tackle the increasing prevalence of ALD and mitigate its extensive impact on individuals and health care systems.

Tapping into alcohol use during COVID: Drinking correlates among bartenders and servers

The COVID pandemic placed a spotlight on alcohol use and the hardships of working within the food and beverage industry, with millions left jobless. Following previous studies that have found elevated rates of alcohol problems among bartenders and servers, here we studied the alcohol use of bartenders and servers who were employed during COVID. From February 12-June 16, 2021, in the midst of the U.S. COVID national emergency declaration, survey data from 1,010 employed bartender and servers were analyzed to quantify rates of excessive or hazardous drinking along with regression predictors of alcohol use as assessed by the 10-item Alcohol Use Disorders Identification Test (AUDIT). Findings indicate that more than 2 out of 5 (44%) people surveyed reported moderate or high rates of alcohol problem severity (i.e., AUDIT scores of 8 or higher)-a rate 4 to 6 times that of the heavy alcohol use rate reported pre- or mid-pandemic by adults within and outside the industry. Person-level factors (gender, substance use, mood) along with the drinking habits of one's core social group were significantly associated with alcohol use. Bartenders and servers reported surprisingly high rates of alcohol problem severity and experienced risk factors for hazardous drinking at multiple ecological levels. Being a highly vulnerable and understudied population, more studies on bartenders and servers are needed to assess and manage the true toll of alcohol consumption for industry employees.

Effects of social drinking context on subjective effects, affect, and next-day appraisals in the natural environment

BACKGROUND

Drinking commonly occurs in social settings and may bolster social reinforcement. Laboratory studies suggest that subjective effects and mood are mechanisms through which the social context influences alcohol consumption. Ecological momentary assessment (EMA) may be useful for extending these findings to the natural environment. This pre-registered secondary analysis of EMA data investigated the influence of the social environment on: (1) stimulating and sedating subjective effects of alcohol, (2) contentedness and negative affect, and (3) next-day evaluations of the drinking occasion.

METHODS

Nontreatment seeking adults reporting past-month heavy drinking (N = 131; Mage = 28.09; 42% female) completed 7 days of EMA (in the morning, at random, and following drinking prompts), which included questions on their social context (drinking in the presence of known others or alone), contemporaneous stimulating and sedating effects, contentedness and negative affect, alcohol consumption, and next-day evaluations of a prior day's drinking event (how satisfying/pleasant was drinking). We used multi-level models in SAS 9.4 M7 software to examine relations among the variables.

RESULTS

Contemporaneous subjective effects (stimulating or sedating), negative affect, and contentedness did not significantly depend on the social context. For next-day evaluations of pleasure/satisfaction from drinking, context effects were dependent on consumption totals. As the total number of standard drinks consumed increased, recollections of pleasure/satisfaction were higher when drinking had occurred with others, relative to alone. At lower consumption totals, next-day evaluations did not appear to depend on social context.

CONCLUSIONS

When reported contemporaneously, subjective effects and affect do not appear dependent upon the presence of known others. However, heavier drinking events, relative to lighter drinking events, are appraised more favorably the following day when occurring within social contexts.

Examining the relationship between the oral microbiome, alcohol intake and alcohol-comorbid neuropsychological disorders: protocol for a scoping review

INTRODUCTION

Heavy alcohol use and alcohol use disorder (AUD) continues to rise as a public health problem and increases the risk for disease. Elevated rates of anxiety, depression, sleep disruption and stress are associated with alcohol use. Symptoms may progress to diagnosed neurophysiological conditions and increase risk for relapse if abstinence is attempted. Research on mechanisms connecting the gastrointestinal microbiome to neuropsychological disorders through the gut-brain axis is well-established. Less is known how the oral microbiome and oral microbial-associated biomarkers may signal to the brain. Therefore, a synthesis of research studying relationships between alcohol intake, alcohol-associated neurophysiological symptoms and the oral microbiome is needed to understand the state of the current science. In this paper, we outline our protocol to collect, evaluate and synthesise research focused on associations between alcohol intake and AUD-related neuropsychological disorders with the oral microbiome.

METHODS AND ANALYSIS

The search strategy was developed and will be executed in collaboration with a medical research librarian. Studies will be screened by two independent investigators according to the aim of the scoping review, along with the outlined exclusion and inclusion criteria. After screening, data will be extracted and synthesised from the included papers according to predefined demographic, clinical and microbiome methodology metrics.

ETHICS AND DISSEMINATION

A scoping review of primary sources is needed to synthesise the data on relationships between alcohol use, neuropsychological conditions associated with AUD and the oral microbiome. The proposed scoping review is based on the data from publicly available databases and does not require ethical approval. We expect the results of this synthesis will identify gaps in the growing literature and highlight potential mechanisms linking the oral-brain axis to addiction and other associated neuropsychological conditions. The study findings and results will be disseminated through journals and conferences related to psychology, neuroscience, dentistry and the microbiome.

Exploring the relationship between solitary drinking and living without other adults on alcohol consumption during the COVID-19 pandemic

AIMS

The COVID-19 pandemic presents the opportunity to learn about solitary drinking as many people were forced to spend time at home. The aim of this study is to examine the relationship between solitary drinking and living without other adults on alcohol consumption.

METHODS

A longitudinal study with four survey waves (between May and November 2020) obtained seven-day drinking diary data from Australian adults living in New South Wales. In May, a convenience sample of 586 participants (Mage = 35.3, SD = 14.8; 65.3% women) completed the first wave. Participants then completed a survey in June (n = 319, 54.4% response rate), July/August (n = 225, 38.4% response rate), and November (n = 222, 37.9% response rate). Information about alcohol consumption including risky drinking (more than four drinks on one occasion), household structure, solitary drinking, and demographics were collected. We conducted random-effects panel bivariate and multivariable regression analyses predicting the number of standard drinks and risky drinking.

RESULTS

Participants with solitary drinking occasions consumed more and had more risky drinking occasions than participants with no solitary drinking occasions, which was also found to be the case during lockdown. Living without other adults was associated with less consumption and less risky drinking than living with other adults. However, participants who lived without other adults and had frequent solitary drinking occasions (solitary drinking in >50% drinking occasions) reported more consumption than participants without a solitary drinking occasion.

CONCLUSIONS

Individuals who consume alcohol alone and live without other adults or spend long periods of time at home may be more at risk of alcohol-related harm.

Differential change in alcohol consumption during the COVID-19 pandemic: the role of loneliness, socialization, and mental well-being

Introduction

The COVID-19 pandemic led to a surge in mental health issues and psychological distress, disruption to work/studying conditions, and social isolation particularly among young adults. Changes in these factors are differentially associated with alcohol use. Moreover, the relationship between these factors are bidirectional and may have fluctuated throughout the different phases of the pandemic. However, studies focusing on young adults had conflicting results, short follow-up periods, and lacked comprehensive data to describe underlying mechanisms.

Methods

1067 young adults participated in repetitive measures termed wave 4 (2021) of the Survey of Adolescent Life in Västmanland Cohort "SALVe" Cohort. Of these, 889 also completed pre-pandemic measurements termed wave 3 (2018). Participants completed the Alcohol Use Disorders Identification Test (AUDIT) to evaluate alcohol consumption and harmful use. Cross-sectional associations between perceived changes in alcohol use and shift in individual, mental health, and work environment factors were examined using Chi-square tests. Logistic regression was utilized to identify pre-pandemic predictors of harmful consumption during the pandemic.

Results

Harmful consumption decreased only in females following the COVID-19 pandemic. Participants who reported increased feelings of depression, anxiety, and loneliness were more likely to increase their alcohol use. Interestingly, the subgroup who felt less lonely and met their friends more often, as well as those who continued working/studying from their regular workplace also had an increased likelihood of higher consumption. Only pre-pandemic ADHD and delinquency symptoms predicted harmful alcohol consumption following the pandemic.

Conclusion

Females reduced harmful alcohol consumption during the COVID-19 pandemic. While those who suffered the burden of social isolation and distress were more likely to increase their alcohol use, young adults who felt less lonely and met their friends more often also had a similar outcome. The relationship between loneliness and alcohol consumption among young adults is influenced by the social factors that may be facilitated by drinking.

Tracking Changes in the Endorsement of Injunctive Drinking Norms in Response to the COVID-19 Pandemic Using Longitudinal Alignment Analysis

The onset of the pandemic saw shifts in messaging around the acceptability of alcohol consumption at different times and contexts. A psychometric analysis of responses to injunctive norms may reveal important differences in specific aspects of norms that were influenced by the pandemic. Study 1 used alignment analysis to evaluate measurement invariance in low- and high-risk injunctive norms across samples of Midwestern college students from 2019 to 2021. Study 2 used an alignment-within-confirmatory factor analysis (CFA) approach to replicate the solution from Study 1 in an independent longitudinal sample (N = 1,148) who responded between 2019 and 2021. For Study 1, the latent mean for high-risk norms was significantly higher in 2021, and the endorsement of four specific norms also differed. In Study 2, increases in latent means for low- and high-risk norms were observed across 2020 and 2021, and differential endorsement emerged for one high-risk norm item. Examining scale-level changes in injunctive drinking norms provides insight into how college students' perceptions changed in response to the COVID-19 pandemic.

Exploring the short-term impact of swapping consumption from standard protein snacks to higher protein snacks on energy intake in social drinkers: Is protein worth a nudge?

Drinking alcoholic beverages stimulates food intake and contributes to the passive overconsumption of dietary energy. As protein is the most satiating of all the macronutrients, increased levels in snacks taken with alcohol have the potential to minimize excess energy consumption. We hypothesized that swapping consumption from retail-available standard protein (SP) snacks to higher protein (HP) snack foods would increase satiety and reduce acute food energy intake in social drinkers. A randomized single-blind crossover trial with 19 healthy participants aged 19-31 years was conducted. Participants attended two separate testing sessions, where they ingested white wine (30 g alcohol) and were offered ad libitum access to either HP snacks with a protein-fortified dip or SP snacks with a dip. There were no significant differences in mean food mass, food energy intake, or subjective appetite ratings between the high and SP snacks (all p > .05). Mean protein intake was significantly increased with HP snacks compared with standard snacks (p < .001). Plasma glucose median incremental area under the curve and mean peak were significantly higher with the SP snacks (all p < .05) but remained within the reference range. This study demonstrated that consumption of a higher amount of protein after a moderate alcohol dose does not result in a change in food mass and energy intake or promote satiety in healthy young adults. The potential for a simple swap to different snack types is unlikely to bring substantial benefits to social drinkers and reduce passive energy consumption.

Prevalence of alcohol use and associated factors since COVID-19 among school-going adolescents within the Southern African Development Community: a systematic review protocol

INTRODUCTION

The COVID-19 pandemic has significantly shaped the global landscape and impacted various aspects of individuals' lives, especially the behaviour of school-going adolescents regarding substance use. Among these substances, alcohol is the most predominant substance, particularly among school-going adolescents, who also are highly susceptible to harmful alcohol use, such as poor academic performance, psychiatric disorders and disrupted social lives. This review will synthesise the known prevalence estimates and associated factors of alcohol use among school-going adolescents in the Southern African Development Community (SADC) since the COVID-19 pandemic.

METHODS AND ANALYSIS

We will perform a systematic review in line with the Cochrane Handbook for Systematic Reviews. We will systematically search for selected global databases (ScienceDirect, EbscoHost, PsycINFO and PubMed) and regional electronic databases (African Index Medicus, Sabinet and African Journals OnLine). Peer-reviewed literature published between 11 March 2020 and 10 March 2024 will be considered for eligibility without language restriction. All 16 countries of the SADC region will be included in the review. The Mixed-Methods Appraisal Tool checklist for quality appraisal will be used to appraise the methodological quality of the included studies. Depending on the level of heterogeneity, prevalence estimates will be pooled in a meta-analysis; narrative synthesis will be applied to describe the reported associated factors of alcohol use.

ETHICS AND DISSEMINATION

We will not seek ethical approval from an institutional review board since the study will not involve gathering data directly from individual school-going adolescents, nor will it violate their privacy. When completed, the full report of this review will be submitted to a journal for peer-reviewed publication; the key findings will be presented at local and international conferences with a partial or full focus on (adolescent) alcohol (mis)use.

Exercising healthy behaviors: A latent class analysis of positive coping during the COVID-19 pandemic and associations with alcohol-related and mental health outcomes

OBJECTIVE

To identify latent classes of positive coping behaviors during the COVID-19 pandemic and examine associations with alcohol-related and mental health outcomes across participants with and without a history of alcohol use disorder (AUD).

METHODS

Baseline data from 463 participants who were enrolled in the NIAAA COVID-19 Pandemic Impact on Alcohol (C19-PIA) Study were analyzed. Latent class analysis (LCA) was applied to five positive coping behaviors during COVID-19: taking media breaks, taking care of their body, engaging in healthy behaviors, making time to relax, and connecting with others. Latent class differences and the moderating role of history of AUD on six alcohol-related and mental health outcomes were examined using multiple regression models.

RESULTS

LCA revealed two latent classes: 83.4% High Positive Coping and 16.6% Low Positive Coping. Low Positive Coping was associated with higher levels of perceived stress, anxiety symptoms, and loneliness. A history of AUD was consistently associated with higher levels of alcohol-related and mental health outcomes. Significant interactions between Coping Latent Classes and history of AUD indicated that the associations of Low Positive Coping with problematic alcohol use, depressive symptoms, and drinking to cope motives were either stronger or only significant among individuals with a history of AUD.

CONCLUSIONS

Individuals with a history of AUD may be particularly vulnerable to depressive symptoms and alcohol-related outcomes, especially when they do not utilize positive coping strategies. The promotion of positive coping strategies is a promising avenue to address alcohol-related and mental health problems during a public health crisis and warrants future research.

Problematic alcohol use and its impact on liver disease quality of life in a multicenter study of patients with cirrhosis

BACKGROUND

Management of cirrhosis is challenging and has been complicated by the COVID-19 pandemic due to decreased access to care, increased psychological distress, and alcohol misuse. Recently, The National Institute on Alcohol Abuse and Alcoholism has broadened the definition of recovery from alcohol use disorder to include quality of life (QoL) as an indicator of recovery. This study examined the associations of alcohol-associated cirrhosis etiology and problematic drinking with liver disease QoL (LDQoL).

METHODS

Patients with cirrhosis (N=329) were recruited from 3 sites (63% from 2 Veterans Affairs Health Care Systems and 37% from 1 safety net hospital) serving populations that are economically or socially marginalized. Cirrhosis etiology was ascertained by chart review of medical records. Problematic drinking was defined by ≥8 on the Alcohol Use Disorders Identification Test. Multivariable general linear modeling adjusting for age, sex, race/ethnicity, site, pandemic-related stress, and history of anxiety/depressive disorder were conducted. Sensitivity analyses further adjusted for indicators of liver disease severity.

RESULTS

Participants were on average 64.6 years old, 17% female, 58% non-White, 44% with alcohol-associated cirrhosis, and 17% with problematic drinking. Problematic drinking was significantly associated with worse LDQoL scores in the overall scale and in the memory/concentration and health distress subscales. These associations remained significant after adjusting for indicators of liver disease severity, including Model for End-Stage Liver Disease-Sodium score and decompensated cirrhosis status.

CONCLUSIONS

Among patients with cirrhosis, problematic drinking was associated with worse LDQoL, especially in the domains of memory/concentration and health distress. Assessment and awareness of cognitive deficits and negative emotionality within the context of cirrhosis and problematic drinking may help clinicians provide better integrated care for this population.

Alcohol's contribution to climate change and other environmental degradation: a call for research

Climate change is the single biggest health threat facing humanity. The production, distribution and consumption of many fast-moving consumer goods contribute substantially to climate change, principally through releasing greenhouse gas emissions. Here we consider just some of the ways that alcohol-already a key contributor to an array of health, social and economic burdens-exacerbates environmental harms and climate change. We explore current evidence on alcohol production as a resource- and energy-intensive process, contributing to significant environmental degradation through water usage and other carbon emission costs. We argue that the impacts of alcohol production on climate change have been minimally explored by researchers. Yet the extent of the unfolding catastrophe beholds us to consider all available ways to mitigate unnecessary emissions, including from products such as alcohol. We then turn to suggestions for a research agenda on this topic, including investigations of commercial determinants, inequalities and product advice to help consumers choose lower-carbon options. We conclude by arguing that public health researchers already have an array of methodological expertise and experience that is well placed to produce the evidence needed to inform regulation and efforts by alcohol producers and consumers to minimize their contributions to environmental harms.

How did COVID-19 restrictions impact alcohol consumption in Australia? A longitudinal study

INTRODUCTION

The state of Victoria experienced more stringent public health measures than other Australian states during the COVID-19 pandemic. This study investigated how these public health measures impacted: (i) total alcohol consumption; (ii) location-specific consumption; and (iii) consumption among different pre-pandemic drinking groups, in Victoria compared to the rest of Australia during the first year of the pandemic.

METHOD

A longitudinal study with six survey waves was conducted between April and December 2020. A total of 775 adults completed data on alcohol use, including detailed consumption location information. Based on their 2019 consumption, participants were classified into low, moderate or high-risk groups. Data were analysed descriptively.

RESULTS

There was no difference in total alcohol consumption from 2019 levels among Victorians and those from the other Australian states when Victoria was the only state in lockdown. Location-specific consumption was relatively similar for Victoria and the rest of Australia, with an increase in home drinking, and a decrease in consumption in someone else's home, licensed premises and public spaces during lockdown compared with 2019. Participants in the high-risk group reported a reduction of two standard drinks per day in November 2020 compared with 2019. In contrast, consumption remained relatively stable for participants in the low and moderate-risk groups once accounting for regression to the mean.

DISCUSSION AND CONCLUSION

Contrary to expectations, restrictions on licensed premises appeared to impact high-risk drinkers more than low and moderate-risk drinkers. Reducing availability of on-premise alcohol may be an effective way to reduce consumption in heavier drinkers.

College Students' Day-to-Day Maladaptive Drinking Responses to Stress Severity and Stressor-Related Guilt and Anger

BACKGROUND

Stress is a common part of college students' daily lives that may influence their physical activity (PA) and alcohol use. Understanding features of daily stress processes that predict health behaviors could help identify targets for just-in-time interventions.

PURPOSE

This study used intensive longitudinal data to examine whether prior day stress processes predict current day PA or alcohol use.

METHODS

Participants (N=58, Mage=20.5, 59% women, 70% White) were 18-to-25-year-old students who engaged in binge drinking at least twice monthly and used cannabis or tobacco in the past year. They wore activity (activPAL4) and alcohol (Secure Continuous Remote Alcohol Monitor) monitors for 11 days to assess daily PA (e.g., step counts) and alcohol use (e.g., drinking day), and completed daily surveys about yesterday's stress, including number of stressors (i.e., frequency), stressor intensity (i.e., severity), and frequency of affective states (e.g., guilt). Multilevel models examined prior day stress predicting current day PA or alcohol use.

RESULTS

Participants had higher odds of current day drinking (odds ratio=1.21) and greater area under the curve (B=0.08) when they experienced greater than usual stress severity the prior day. Participants had higher current day peak transdermal alcohol concentration (B=0.12) and area under the curve (B=0.11) when they more frequently experienced guilt due to stressors the prior day.

CONCLUSIONS

College students' unhealthy response of increasing alcohol use due to stress could adversely impact health outcomes. There is a critical need for interventions addressing students' ability to effectively manage and respond to the stress-inducing, daily demands of student life.

A Qualitative Exploration of Intimate Partner Violence Among HIV/TB Coinfected Persons With Problematic Alcohol Use Participating in an Incentive-Based Alcohol/Medication Adherence Intervention in Uganda During COVID-19

In Uganda, four in ten women report experiencing intimate partner violence (IPV) in the past year. Salient drivers of IPV in sub-Saharan Africa include stress related to household finances, alcohol use, and partner infidelity. We conducted 42 interviews with participants (n = 32) in the Drinkers' Intervention to Prevent Tuberculosis (DIPT) study which included economic incentives, and their partners (n = 10) to understand how participating in DIPT during COVID-19 lockdown restrictions impacted relationship dynamics in intimate partnerships. Our findings highlight the need to develop policies to address root causes of IPV and to ensure continuity of IPV services in future pandemics. Policy and programming recommendations based on study results are presented.

[Trends in the incidence of mental and behavioral disorders during the COVID-19 pandemic in Penza Oblast]

OBJECTIVE

An analysis of the trend of overall and primary incidence of mental and behavioral disorders, including those caused by the use of psychoactive substances, in different age groups during the COVID-19 pandemic in Penza Oblast.

MATERIAL AND METHODS

The data were obtained from statistical report №12 for Penza Oblast. These included the overall and primary incidence of mental and behavioral disorders (MBD), as well as substance use-related MBD (MBDSUR), as calculated per 100.000 people for the period 2015 to 2022. The period 2015 to 2019 was the reference period and 2020 to 2022 was the pandemic period. The calculation was carried out by age groups: children (0-14 years), adolescents (15-17 years), adults (over 18 years), adults over working age (from 55 years for women and from 60 years for men). Statistical processing of the results included regression analysis, calculation of incidence forecast for 2023-2025, and assessment of the significance of the changes using the t-criterion.

RESULTS

The decrease in the overall incidence of MBD in adults was highly deterministic (R2=0.82; p=0.012) and significant between 2017-2018 (p=0.009), 2018-2019 (p=0.001) and 2019-2020 (p=0.004). High determination with a logarithmic trend line was characteristic of almost all models, except for the primary incidence of MBD in children and overall incidence of MBDSUR in adults over working age, including after 2020. Among adolescents, the overall incidence of MBDSUR decreased significantly from 2015 to 2022 (p=0.042).

CONCLUSION

There was no significant increase in the incidence of MBD, including MBDURS, during the pandemic. At the same time, there was a trend towards the decrease in adults, as well as the increase in the primary incidence of MBD in children and the overall incidence of MBDSUR in adults over working age, which determines the need for further identification of risk factors and development of specific rehabilitation measures for patients in these groups.

The politics of COVID-19: Differences between U.S. red and blue states in COVID-19 regulations and deaths

The study investigated infection variables and control strategies in 2020 and 2021 and their influence on COVID-19 deaths in the United States, with a particular focus on comparing red (Republican) and blue (Democratic) states. The analysis reviewed cumulative COVID-19 deaths per 100,000 by year, state political affiliation, and a priori latent factor groupings of mitigation strategies (lockdown days in 2020, mask mandate days, vaccination rates), social demographic variables (ethnicity, poverty rate), and biological variables (median age, obesity). Analyses first identified possible relationships between all assessed variables using K-means clustering for red, blue, and purple states. Then, a series of regression models were fit to assess the effects of mitigation strategies, social, and biological factors specifically on COVID-19 deaths in red and blue states. Results showed distinct differences in responding to COVID infections between red states to blue states, particularly the red states lessor adoption of mitigation factors leaving more sway on biological factors in predicting deaths. Whereas in blue states, where mitigation factors were more readily implemented, vaccinations had a more significant influence in reducing the probability of infections ending in death. Overall, study findings suggest politicalization of COVID-19 mitigation strategies played a role in death rates across the United States.

High-resolution examination of changes in drinking during the COVID-19 pandemic: Nine-wave findings from a longitudinal observational cohort study of community adults

Few multi-wave longitudinal studies have examined changes in drinking across extended periods of the coronavirus 2019 (COVID-19) pandemic. Using multiple indicators over three years, the current study examined: a) overall drinking changes; b) sex, income, age, and pre-COVID drinking level as moderators of changes; and c) the clinical significance of the observed changes. Using a longitudinal observational cohort design with nonclinical adults from the general community (N = 1395), assessments were collected over nine waves, two pre-COVID (April 2019 and October 2019) and seven intra-COVID (April 2020-April 2022). Drinking was measured as percent drinking days, percent heavy drinking days, and the Alcohol Use Disorders Identification Test (AUDIT) score. Clinically significant changes were defined based on the World Health Organization risk levels. All indicators exhibited significant changes from pre-pandemic to intra-pandemic periods, with drinking changes comprising early pandemic increases followed by subsequent decreases and AUDIT scores consistently declining. Pre-pandemic drinking level substantially moderated all changes. Heavier drinkers exhibited larger decreases compared to other drinking groups. In terms of clinically important changes, ∼10% of pre-pandemic abstinent or low-risk drinkers transitioned to medium- or high-risk status during the pandemic. In contrast, 37.1% of medium-risk drinkers and 44.6% of high-risk drinkers exhibited clinically significant decreases during the intra-pandemic period. Collectively, these findings highlight the multifarious impacts of the pandemic on drinking over time, comprising both increases and decreases in drinking behaviour.

The impact of the COVID-19 pandemic experiences on college drinking via mental distress: Cross-sectional mediation moderated by race

BACKGROUND

The COVID-19 pandemic has been linked to stress, anxiety, and depression among college students, with heightened distress tied to greater drinking for some individuals. Emerging research suggests that these associations may differ across race, but few studies use adequate samples to examine this, particularly among college students, an at-risk population for both heavy drinking and mental distress. Specifically, pandemic-related stressors and mental distress may be higher among Black students than White students. The current study examined: (1) whether mental distress cross-sectionally mediates the association between pandemic-specific stressors and drinking and (2) whether race (Black or White) moderates these associations.

METHODS

A cross-sectional online survey of 400 college drinkers (43% White, 28% Black) in fall 2020 assessed pandemic-related stressors (e.g., losing a job, contracting COVID-19, changed living situation), mental distress (stress, anxiety, depression), and drinking (past-month drinking, perceived changes since the start of the pandemic).

RESULTS

Cross-sectional mediation models indicated that financial stressors and social distancing were linked to greater quantity and frequency of past-month drinking through greater mental distress. For perceived changes in drinking, only financial stressors were linked to drinking greater quantities and drinking more often (compared to pre-pandemic levels) via mental distress. Moderated mediation models among students identifying as White or Black revealed that changed living situation was a robust stressor across race. Financial stressors and social distancing were linked with greater distress only among White students, whereas essential worker status was a protective factor against distress only among Black students.

CONCLUSIONS

Select stressors were linked to increased drinking through greater mental distress, with differential risks across Black versus White students. Findings suggest campus administrators should focus on connecting students with resources (e.g., counseling centers and health promotion offices) during times of distress.

Changes in Alcohol-Specific Mortality During the COVID-19 Pandemic in 14 European Countries

Aim

Exploring trends in 1) alcohol-specific mortality and 2) alcohol sales in European countries in the years before and during the COVID-19 pandemic.

Method

Complete data on alcohol-specific mortality and alcohol sales were obtained for 14 European countries (13 EU countries and UK) for the years 2010 to 2020, with six countries having mortality data available up to 2021. Age-standardised mortality rates were calculated and descriptive statistics used.

Results

When compared to 2019, alcohol-specific mortality rates in 2020 increased by 7.7 % and 8.2 % for women and men, respectively. Increases in alcohol-specific mortality were seen in the majority of countries and continued in 2021. In contrast, alcohol sales declined by an average of 5.0 %.

Conclusion

Despite a drop in alcohol consumption, more people died due to alcohol-specific causes during the COVID-19 pandemic in Europe.

COVID-19 Concerns, Coping and Perceived Peer Norms: Correlates of Increased Alcohol and Marijuana Use Among Sexual Minority Women

This study explored the impact of COVID-related concerns and other characteristics on alcohol and marijuana use among sexual minority women (SMW). Survey data from a racially/ethnically diverse sample of 338 SMW participants in the Chicago Health and Life Experiences of Women (CHLEW) study were used to examine correlates of three substance use outcomes: frequent intoxication (once a month or more), perceived increase in alcohol use, and perceived increase in marijuana use. Coping motives for alcohol use was positively associated with each of the substance use outcomes. Belief that peers (in terms of age, sexual identity, and gender) used alcohol often to cope was associated with higher odds of frequent intoxication. COVID-19 related financial concerns were positively associated with both frequent intoxication and increased marijuana use. Health and mental health concerns were associated with lower odds of frequent intoxication. Findings underscore the importance of enhancing coping skills, addressing perceived peer coping norms, and providing both economic and social support in intervention efforts.

Social media addiction as a mediator of the associations between fear of COVID-19, mental health symptoms, and problematic alcohol use

Background

Fear of COVID-19 is a risk factor for anxiety and depressive symptoms. During the COVID-19 pandemic, drinking to cope with psychological distress has been proposed as a key mechanism leading to problematic drinking. The goal of this study was to test social media addiction as a mediator linking fear of COVID-19 to mental health symptoms and problematic alcohol use.

Methods

In between April 6 and July 2 of 2022, 250 participants completed an online survey as part of the National Institute on Alcohol Abuse and Alcoholism COVID-19 Pandemic Impact on Alcohol Study. Path analyses were conducted to test the mediational pathways.

Results

Using the polythetic classification scheme, 13.2% (n = 33) of participants were classified as having social media addiction. Compared with participants without social media addiction, participants with social media addiction spent significantly more time on social media platforms and on digital communications with a family member or friend. They also reported greater fear of COVID-19, higher anxiety symptoms, and higher depressive symptoms. Path analyses indicated that social media addiction mediated the associations of fear of COVID-19 with anxiety and depressive symptoms. Furthermore, there were indirect pathways linking fear of COVID-19 to problematic alcohol use through higher social media addiction and higher anxiety and depressive symptoms.

Conclusion

Social media addiction may be a maladaptive coping mechanism that individuals with high fear of COVID-19 utilized to deal with uncertainty and perceived risks during the pandemic. Findings underscore the need to examine cognitions related to fear of COVID-19 and address excessive social media use in the context of mental health and alcohol interventions.

Navigating the Shifts: Retrospective Analysis of Alcohol Consumption and its Predictors Across Pre-Pandemic, Lockdown, and Post-Pandemic Eras in Poland

BACKGROUND Alcohol consumption is a serious health risk that affects both physical and mental health. It is one of the major risk factors in the development of non-communicable diseases. The aim of this study was to perform a retrospective analysis of alcohol consumption patterns, determine of predictors of alcohol addiction, and attempt to distinguish and compare the profiles of participants differentiated in terms of their preferences in the pre-pandemic, lockdown, and post-pandemic periods. MATERIAL AND METHODS A retrospective study was conducted with a computer-assisted web interview on a representative sample of Polish citizens. Primary outcomes were sociodemographic and COVID-19-related variables, preferences regarding the type and location of consumed alcohol, reasons for drinking, severity of addiction symptoms, loneliness, quality of life, and health level. RESULTS During the lockdown period, the percentage of people declaring abstinence increased, as well as people who, according to the Alcohol Use Disorders Identification Test (AUDIT) cut-off points, could be diagnosed with probable alcohol dependence. The strongest predictors of the severity of addiction symptoms were preferences regarding the type and place of alcohol consumption, with a high percentage of explained variance (>50%). The analysis of profiles differentiated in terms of the preferred type of alcohol consumed allowed for the identification of 7 different profiles, which differed in terms of AUDIT score, loneliness, quality of life, and level of health. CONCLUSIONS Patterns of alcohol consumption changed during the pandemic. Alcohol-related preferences are important from the public health perspective.

Beverage- and Context-Specific Alcohol Consumption During COVID-19 in the United States: The Role of Alcohol To-Go and Delivery Purchases

OBJECTIVE

Alcohol delivery and to-go sales may contribute to changes in drinking patterns, including where and what people drink. This study tested whether home delivery and to-go alcohol purchases were associated with context- and beverage-specific consumption volumes during the first year of the COVID-19 pandemic after adjusting for pre-pandemic consumption volumes.

METHOD

Data from a pre-pandemic panel were compared to a during-pandemic panel of the National Alcohol Survey (n = 1,150 adult drinkers, 52.7% female). Outcomes were past-year alcohol consumption volumes in standard drinks (overall, by beverage type, and by location). Independent variables included past-year alcohol delivery and to-go purchases (separately). Covariates comprised baseline beverage- or context-specific volume, demographics, COVID-19 impacts, and drinking motivations. Negative binomial regression tested associations between alcohol purchases and change in overall, beverage-, and context-specific consumption.

RESULTS

On average, respondents who had alcohol delivered (vs. not) reported consuming larger volumes overall (incidence rate ratio [IRR] = 1.58, 95% CI [1.07, 2.32], p = .02), of wine (IRR = 2.90, 95% CI [1.50, 5.63], p < .04), of spirits (IRR = 1.59, 95% CI [1.03, 2.44], p = .04), and at home (IRR = 1.59, 95% CI [1.10, 2.31], p = .01). People who bought alcohol to go (vs. not) reported larger volumes of wine (IRR = 1.41, 95% CI [1.02, 1.96], p = .04), at home (IRR = 1.60, 95% CI [1.10, 2.32], p = .01), and in bars (IRR = 4.55, 95% CI [2.55, 8.11], p < .001). Finally, people who had alcohol delivered reported drinking smaller volumes in bars (IRR = 0.49, 95% CI [0.24, 0.98], p = .04).

CONCLUSIONS

During the first year of the pandemic, adults who had alcohol delivered or bought it to go reported larger volumes for several locations and beverage types.

Effects of a COVID-19 Public Health Lockdown on Drinking and Health Behavior Among Persons with HIV and with Unhealthy Alcohol use in Uganda

To better understand the impact of Uganda's initial COVID-19 lockdown on alcohol use, we conducted a cross-sectional survey (August 2020-September 2021) among persons with HIV (PWH) with unhealthy alcohol use (but not receiving an alcohol intervention), enrolled in a trial of incentives to reduce alcohol use and improve isoniazid preventive therapy. We examined associations between bar-based drinking and decreased alcohol use, and decreased alcohol use and health outcomes (antiretroviral therapy [ART] access, ART adherence, missed clinic visits, psychological stress and intimate partner violence), during lockdown. Of 178 adults surveyed whose data was analyzed, (67% male, median age: 40), 82% reported bar-based drinking at trial enrollment; 76% reported decreased alcohol use during lockdown. In a multivariate analysis, bar-based drinking was not associated with greater decreases in alcohol use during lockdown compared to non-bar-based drinking (OR = 0.81, 95% CI: 0.31-2.11), adjusting for age and sex. There was a significant association between decreased alcohol use and increased stress during lockdown (adjusted β = 2.09, 95% CI: 1.07-3.11, P < 0.010), but not other health outcomes.

The impact of COVID-19 on alcohol sales and consumption in the United States: A retrospective, observational analysis

Understanding the COVID-19 pandemic's effect on alcohol sales and consumption is critical in mitigating alcohol abuse and morbidity. We sought to determine how the onset of the COVID-19 pandemic and changes in viral incidence affected alcohol sales and consumption in the United States. We conducted a retrospective observational analysis regressing National Institute on Alcohol Abuse and Alcoholism (NIAAA) alcohol sales data and Behavioral Risk Factor Surveillance System (BRFSS) survey data for 14 states for 2017 to 2020 with COVID-19 incidence in 2020 in the United States. The onset of the pandemic was associated with higher monthly alcohol sales per capita of 1.99 standard drinks (95% Confidence Interval: 0.63 to 3.34, p = 0.007). Increases of one COVID-19 case per 100 were associated with lower monthly alcohol sales per capita of 2.98 standard drinks (95% CI: -4.47 to -1.48, p = 0.001) as well as broad decreases in alcohol consumption, notably 0.17 fewer days per month with alcohol use (95% CI: -0.31 to -0.23, p = 0.008) and 0.14 fewer days per month of binge drinking (95% CI: -0.23 to -0.052, p < 0.001). The COVID-19 pandemic is associated with increased monthly average alcohol purchases, but higher viral incidence is linked to lower alcohol purchases and consumption. Continued monitoring is needed to mitigate the effects of higher population alcohol use during the pandemic.

Substance use disorders and COVID-19: reflections on international research and practice changes during the "poly-crisis"

Since March 2020, the COVID-19 pandemic has had a disproportionately high toll on vulnerable populations, coinciding with increased prevalence of alcohol-and drug-related deaths and pre-existing societal issues such as rising income inequality and homelessness. This poly-crisis has posed unique challenges to service delivery for people with substance use disorders, and innovative approaches have emerged. In this Perspectives paper we reflect on the poly-crisis and the changes to research and practice for those experiencing substance use disorders, following work undertaken as part of the InterGLAM project (part of the 2022. Lisbon Addictions conference). The authors, who were part of an InterGLAM working group, identified a range of creative and novel responses by gathering information from conference attendees about COVID-19-related changes to substance use disorder treatment in their countries. In this paper we describe these responses across a range of countries, focusing on changes to telehealth, provision of medications for opioid use disorder and alcohol harm reduction, as well as changes to how research was conducted. Implications include better equity in access to technology and secure data systems; increased prescribed safer supply in countries where this currently does not exist; flexible provision of medication for opioid use disorder; scale up of alcohol harm reduction for people with alcohol use disorders; greater involvement of people with lived/living experience in research; and additional support for research in low- and middle-income countries. The COVID-19 pandemic has changed the addictions field and there are lessons for ongoing and emerging crises.

Trends in Public Awareness and Knowledge of Drinking Guidelines: a Representative Population Survey in England, 2016-2022

AIM

To examine trends in public awareness and knowledge of drinking guidelines in the UK since their revision in 2016, which had moved from a daily to a weekly guideline, made the guideline the same for men and women, and reduced the guideline for men by around one-third.

METHOD

Data were from a representative, repeat cross-sectional survey. We analysed changes in awareness and knowledge of drinking guidelines among 8168 adult drinkers between 2016 and 2022 and associations with sociodemographic characteristics, smoking status and level of alcohol consumption.

RESULTS

The proportion of drinkers aware of guidelines declined from 86.0% (95%CI 84.0-88.0%) in 2016 to 81.7% (79.5-84.0%) in 2019, then increased during the COVID-19 pandemic, peaking at 91.6% (90.1-93.1%) in 2020. The proportion who correctly identified the guideline as a maximum of exactly 14 units/week remained at around a quarter from 2016 (25.0%, 22.4-27.5%) to 2018 (25.8%, 23.2-28.3%), whereas the proportion who gave a figure of 14 units or fewer rose from 52.1 (49.2-55.0%) to 57.4% (54.6-60.3%). However, by 2022, guideline knowledge had worsened significantly, with these figures falling to 19.7 (17.4-21.9%) and 46.5% (43.6-49.4%), respectively. Changes over time were similar across subgroups. Odds of guideline awareness and knowledge were higher among drinkers who were aged ≥35, female, more educated and from more advantaged social grades.

CONCLUSIONS

The majority of adult drinkers in the UK are aware of low-risk drinking guidelines. However, 6 years since their announcement, knowledge of the revised drinking guidelines remains poor. Less than a quarter know the recommended weekly limit and only around half think it is 14 units or less. Inequalities have persisted over time, such that disadvantaged groups remain less likely to know the guidelines.

Longitudinal factors associated with increased alcohol consumption in adults during the COVID-19 pandemic

Background: Alcohol is the most abused substance among adults in the United States. The COVID-19 pandemic impacted patterns of alcohol use, but data are conflicting, and previous studies are largely limited to cross-sectional analyses.Objective: This study aimed to longitudinally assess sociodemographic and psychological correlates of changes in three patterns of alcohol use (number of alcoholic drinks, drinking regularity, and binge drinking) during COVID-19.Methods: We studied changes in self-reported drinking behaviors in 222,195 Mayo Clinic patients over 21 years of age (58.1% female and 41.9% male) between April 1, 2019, and March 30, 2021. Logistic regression models were used to estimate associations between patient characteristics and change in alcohol consumption.Results: Sociodemographically younger age, White race, having a college degree, and living in a rural area were associated with increased alcohol use regularity (all p < .05). Younger age, male, White, high-school education or less, living in a more deprived neighborhood, smoking, and living in a rural area were associated with increases in number of alcohol drinks (all p ≤ .04) and binge drinking (all p ≤ .01). Increased anxiety scores were associated with increased number of drinks, while depression severity was associated with both increased drinking regularity and increased number of drinks (all p ≤ .02) independent of sociodemographic characteristics.Conclusion: Our study showed that both sociodemographic and psychological characteristics were associated with increased alcohol consumption patterns during the COVID-19 pandemic. Our study highlights specific target groups previously not described in the literature for alcohol interventions based on sociodemographic and psychological characteristics.

Characteristics associated with buying alcohol to-go and for delivery during the first year of the COVID-19 pandemic among a national sample of US adults

INTRODUCTION

This study: (i) determined the population coverage of alcohol delivery and to-go/carryout policies (i.e., policies permitting bars/restaurants to sell individual drinks for off-site consumption) in 2019 and 2020; and (ii) identified characteristics associated with alcohol delivery and to-go purchases.

METHODS

Data are from the National Alcohol Survey and Alcohol Policy Information System (n = 1677 adults, 52.1% female). Population coverage models summed state populations across state-level bar/restaurant delivery and to-go/carryout policies by beverage. Regression outcomes were past-year alcohol delivery and to-go purchases. Independent variables included demographics, excessive drinking, COVID-19 impacts and state COVID-19 bar/restaurant alcohol laws. Chi-squared tests and logistic regression models tested associations between delivery/to-go purchases and independent variables.

RESULTS

Overall, 7.5% of adults had alcohol delivered and 14.5% bought alcohol to-go. From December 2019 to December 2020, the number of people living in states allowing beer/wine/spirits delivery (284%) and to-go sales (627%) rose steeply. People who were Black (vs. White; adjusted odds ratio [aOR] 2.92, p < 0.001), excessive drinkers (vs. non-excessive drinkers; aOR 2.06, p < 0.001) or lived in states allowing beer/wine/spirits to-go sales (aOR 2.20, p = 0.01) had higher odds of buying alcohol to-go. Conversely, older people had lower odds of buying alcohol to-go (aOR 0.97, p < 0.001). People with some college or more (vs. high school degree or less, aOR 2.21, p < 0.001) and a higher economic burden (vs. fewer COVID-19 impacts, aOR 2.32, p = 0.05) had higher odds of alcohol delivery.

DISCUSSION AND CONCLUSIONS

A select sub-population defined by socioeconomic status, race, excessive drinking and state policies bought alcohol for delivery or to-go in the Unites States.
