Changes in Alcohol Consumption during the COVID-19 Pandemic-Small Change in Total Consumption, but Increase in Proportion of Heavy Drinkers

Impact of the pandemic on leisure physical activity and alcohol consumption

BACKGROUND

The COVID-19 pandemic precipitated heightened morbidity and elevated mortality attributed to the SARS-CoV-2 infection. The pandemic also influenced health behaviors such as physical activity (PA) and alcohol consumption. The aim of this study was to examine changes in leisure PA and alcohol consumption in Sweden during the pandemic, and elucidate potential discrepancies in changes across demographic strata and socioeconomic status (SES).

METHODS

Data were retrieved from two waves of the longitudinal cohort study Life conditions, Stress and Health (LSH) (n = 2,523). Two measures of change were used; longitudinal change relative to baseline (2012-2015) and reported change compared to before the pandemic. For these two change measures, differences between sex, age group and SES were analyzed using multinomial logistic regression.

RESULTS

Regardless of the change measure, the proportion of individuals with diminished PA was notably higher among females compared to males. Furthermore, relative to baseline, females were less likely to have increased their PA, however according to the reported change they were more likely to have increased PA. Longitudinal change in PA compared to baseline followed a reversed age gradient, while, according to reported change, a decrease in PA during the pandemic was most prevalent in respondents 45 years of age at baseline (OR = 1.8, CI: 1.2-2.5) and respondents 50 years of age at baseline (OR = 1.7, CI: 1.2-2.4). High SES was associated with a greater variability in PA. Alcohol consumption was generally reduced during the pandemic. However, individuals aged 40 or 45 years at baseline were more likely than others to have initiated risky alcohol consumption.

CONCLUSIONS

Females exhibited a greater propensity to alter their PA levels during the pandemic, with the most profound decreases observed among individuals of working ages. Despite a general downturn in alcohol consumption, individuals aged 40 and 45 had a heightened likelihood of having initiated risky alcohol consumption compared to individuals in other age cohorts. In conclusion, societal restrictions during a pandemic render a dual impact on PA levels. While posing a risk for decreased PA among individuals in working ages, the restrictions also present a potential window of opportunity to increase PA, particularly among females.

The association between alcohol retail access and health care visits attributable to alcohol for individuals with and without a history of alcohol-related health-care use

BACKGROUND AND AIMS

Alcohol retail access is associated with alcohol use and related harms. This study measured whether this association differs for people with and without heavy and disordered patterns of alcohol use.

DESIGN

The study used a repeated cross-sectional analysis of health administrative databases.

SETTING, PARTICIPANTS/CASES

All residents of Ontario, Canada aged 10-105 years with universal health coverage (n = 10 677 604 in 2013) were included in the analysis.

MEASUREMENTS

Quarterly rates of emergency department (ED) and outpatient visits attributable to alcohol in 464 geographic regions between 2013 and 2019 were measured. Quarterly off-premises alcohol retail access scores were calculated (average drive to the closest seven stores) for each geographic region. Mixed-effect linear regression models adjusted for area-level socio-demographic covariates were used to examine associations between deciles of alcohol retail access and health-care visits attributable to alcohol. Stratified analyses were run for individuals with and without prior alcohol-attributable health-care use in the past 2 years.

FINDINGS

We included 437 707 ED visits and 505 271 outpatient visits attributable to alcohol. After adjustment, rates of ED visits were 39% higher [rate ratio (RR) = 1.39, 95% confidence interval (CI) = 1.20-1.61] and rates of outpatient visits were 49% higher (RR = 1.49, 95% CI = 1.26-1.75) in the highest versus lowest decile of alcohol access. There was a positive association between alcohol access and outpatient visits attributable to alcohol for individuals without prior health-care attributable to alcohol (RR = 1.65, 95% CI = 1.39-1.95 for the highest to lowest decile of alcohol access) but not for individuals with prior health-care attributable to alcohol (RR = 1.08, 95% CI = 0.90-1.30). There was a positive association between alcohol access and ED visits attributable to alcohol for individuals with and without prior health-care for alcohol for ED visits.

CONCLUSION

In Ontario, Canada, greater alcohol retail access appears to be associated with higher rates of emergency department (ED) and outpatient health-care visits attributable to alcohol. Individuals without prior health-care for alcohol may be more susceptible to greater alcohol retail access for outpatient but not ED visits attributable to alcohol.

Alcohol consumption under lockdown measures during the COVID-19 pandemic in three Nordic countries

BACKGROUND

At the beginning of the COVID-19 pandemic, concerns arose about a possible rise in alcohol consumption. Early surveys, however, more commonly pointed towards a decrease of alcohol use. But studies based on self-reports may underestimate alcohol use. They also depend on the population sampled. Because of border closures and gastronomy restrictions, countries with centralised alcohol sales provided a unique opportunity to study total domestic consumption during the pandemic without influence of private import or reliance on self-reports.

AIMS

We examined the correlation between alcohol sales and national COVID-19 restrictions in three such countries, Finland, Norway and Sweden.

METHOD

We conducted this study as a mirror image study, comparing alcohol sales during the first 2 years of the COVID-19 pandemic with the two preceding years. We explored hours of daylight/season as potential confounders.

RESULTS

We found no relevant change in alcohol sales during the pandemic years for Finland or Sweden. For Norway, there was a level-change in sales, which could be explained by decreased imports. Sales followed a seasonal pattern. In all three countries, the initial pandemic increase in alcohol sales coincided with an underlying annually recurring seasonal variation.

CONCLUSIONS

The COVID-19 pandemic had less of an impact on alcohol consumption in the three Nordic countries than could intuitively be expected. The increase of alcohol sales at the beginning of the COVID-19 pandemic coincided with a seasonal rise following a pre-pandemic pattern. Therefore, caution should be exercised with drawing conclusions from data with a short time perspective to avoid attribution bias.

Liver biopsy for assessment of suspected drug-induced liver injury in metabolic dysfunction-associated steatohepatitis clinical trials: Expert consensus from the Liver Forum

BACKGROUND

Causality assessment of suspected drug-induced liver injury (DILI) during metabolic dysfunction-associated steatohepatitis (MASH) clinical trials can be challenging, and liver biopsies are not routinely performed as part of this evaluation. While the field is moving away from liver biopsy as a diagnostic and prognostic tool, information not identified by non-invasive testing may be provided on histology.

AIM

To address the appropriate utilisation of liver biopsy as part of DILI causality assessment in this setting.

METHODS

From 2020 to 2022, the Liver Forum convened a series of webinars on issues pertaining to liver biopsy during MASH trials. The Histology Working Group was formed to generate a series of consensus documents addressing these challenges. This manuscript focuses on liver biopsy as part of DILI causality assessment.

RESULTS

Expert opinion, guidance and recommendations on the role of liver biopsy as part of causality assessment of suspected DILI occurring during clinical trials for a drug(s) being developed for MASH are provided. Lessons learned from prior MASH programs are reviewed and gaps identified.

CONCLUSIONS

Although there are no pathognomonic features, histologic evaluation of suspected DILI during MASH clinical trials may alter patient management, define the pattern and severity of injury, detect findings that favour a diagnosis of DILI versus MASH progression, identify prognostic features, characterise the clinicopathological phenotype of DILI, and/or define lesions that influence decisions about trial discontinuation and further development of the drug.

Impact of the COVID-19 pandemic on acute mental health admissions in Croatia

Background

The pandemic of COVID-19 had a profound impact on our community and healthcare system. This study aims to assess the impact of COVID-19 on psychiatric care in Croatia by comparing the number of acute psychiatric cases before coronavirus disease (2017-2019) and during the pandemic (2020-2022).

Materials and methods

The paper is a retrospective, comparative analyzes of the hospital admission rate in Diagnosis Related Group (DRG) classes related to mental diseases, and organic mental disorders caused by alcohol and drug use. This study used DRG data from all acute hospitals in Croatia accredited to provide mental health care services and relevant publicly available data from the Croatian Institute of Public Health (CIPH) and the Croatian Health Insurance Fund (CHIF). All hospital admissions for acute psychiatric patients in Croatia were tracked during both periods under study.

Results

During the pandemic, the average number of all such cases decreased by 28% in secondary and tertiary hospitals, and by 11% in specialist psychiatric hospitals. It was also found that during COVID-19, there was a decrease in case numbers in DRG classes related to major affective disorders and anxiety, alcohol, and drug intoxication (31, 48, 34 and 45%, respectively). However, the same period saw an increase in hospital activity for eating disorders and for involuntary admissions related to schizophrenia and paranoia (30, 34 and 39% respectively). There were no changes in the admission rate for cases related to opioid use.

Conclusion

The COVID-19 pandemic resulted in both a steep decrease in the overall number of psychiatric cases inpatient treatment at mental health facilities and their DRG casemix. Increasing our understanding of how pandemics and isolation affect demand for psychiatric care will help us better plan for future crises and provide more targeted care to this vulnerable group.

Application of Machine Learning Algorithms to Classify Peruvian Pisco Varieties Using an Electronic Nose

Pisco is an alcoholic beverage obtained from grape juice distillation. Considered the flagship drink of Peru, it is produced following strict and specific quality standards. In this work, sensing results for volatile compounds in pisco, obtained with an electronic nose, were analyzed through the application of machine learning algorithms for the differentiation of pisco varieties. This differentiation aids in verifying beverage quality, considering the parameters established in its Designation of Origin". For signal processing, neural networks, multiclass support vector machines and random forest machine learning algorithms were implemented in MATLAB. In addition, data augmentation was performed using a proposed procedure based on interpolation-extrapolation. All algorithms trained with augmented data showed an increase in performance and more reliable predictions compared to those trained with raw data. From the comparison of these results, it was found that the best performance was achieved with neural networks.

Changes in health service use due to alcohol during the COVID-19 pandemic among individuals with and individuals without pre-existing alcohol-related medical diagnoses

OBJECTIVE

To compare changes in outpatient and acute care visits due to alcohol during the COVID-19 pandemic between individuals with and those without a history of alcohol-related health service use (AHSU).

METHODS

We conducted a cross-sectional analysis of health administrative data in Ontario, Canada. The Ontario population was stratified into those with and those without 1+ health service encounter(s) due to alcohol in the past 2 years. We compared age- and sex-standardized rates of alcohol-related outpatient visits, emergency department (ED) visits, and hospitalizations during the first 15 months of the pandemic (March 2020-May 2021) to those during the same 15-month period prior to the pandemic (March 2018-May 2019).

RESULTS

Of 13,450,750 eligible Ontarians on March 11, 2022, 129,434 (1.0%) had AHSU in the previous 2 years. Overall, rates of alcohol-related outpatient visits and hospitalizations increased, while rates of alcohol-related ED visits decreased during the pandemic. There was a similar relative increase in rates of alcohol-related outpatient visits and hospitalizations between those with and those without prior AHSU. However, the absolute increase in rates of alcohol-related outpatient visits and hospitalizations was higher among those with prior AHSU (outpatient rate difference (RD) per 10,000 population: 852.3, 95% confidence interval (CI): 792.7, 911.9; inpatient RD: 26.0, 95% CI: -2.3, 54.2) than among those without (outpatient RD: 6.5, 95% CI: 6.0, 6.9; inpatient RD: 0.4, 95% CI: 0.2, 0.7).

CONCLUSION

Rates of alcohol-related outpatient and inpatient care increased during the COVID-19 pandemic, and high rate of recurrent harm among individuals with pre-pandemic AHSU was an important contributor to this trend.

Alcohol and lactation: Developmental deficits in a mouse model

It is well documented that prenatal ethanol exposure via maternal consumption of alcohol during pregnancy alters brain and behavioral development in offspring. Thus, the Centers for Disease Control (CDC) advises against maternal alcohol consumption during pregnancy. However, little emphasis has been placed on educating new parents about alcohol consumption while breastfeeding. This is partly due to a paucity of research on lactational ethanol exposure (LEE) effects in children; although, it has been shown that infants exposed to ethanol via breast milk frequently present with reduced body mass, low verbal IQ scores, and altered sleeping patterns. As approximately 36% of breastfeeding mothers in the US consume alcohol, continued research in this area is critical. Our study employed a novel murine LEE model, where offspring were exposed to ethanol via nursing from postnatal day (P) 6 through P20, a period correlated with infancy in humans. Compared to controls, LEE mice had reduced body weights and neocortical lengths at P20 and P30. Brain weights were also reduced in both ages in males, and at P20 for females, however, female brain weights recovered to control levels by P30. We investigated neocortical features and found that frontal cortex thickness was reduced in LEE males compared to controls. Analyses of dendritic spines in the prelimbic subdivision of medial prefrontal cortex revealed a trend of reduced densities in LEE mice. Results of behavioral tests suggest that LEE mice engage in higher risk-taking behavior, show abnormal stress regulation, and exhibit increased hyperactivity. In summary, our data describe potential adverse brain and behavioral developmental outcomes due to LEE. Thus, women should be advised to refrain from consuming alcohol during breastfeeding until additional research can better guide recommendations of safe maternal practices in early infancy.

Change in Alcohol Use during the Prolonged COVID-19 Pandemic and Its Psychosocial Factors: A One-Year Longitudinal Study in Japan

This study investigated changes in alcohol use and its related psychosocial factors during the COVID-19 pandemic in Japan. Two online surveys were completed by participants between 15 and 20 June 2021 (phase 1) and 13 and 30 May 2022 (phase 2). A total of 9614 individuals participated in both phases (46% women, mean age = 50.0 ± 13.1 years) and a repeated three-way analysis of variance and multinomial logistic regression analysis were conducted. These data analyses showed that the presence of hazardous alcohol use at phase 2 was predicted by being male and unmarried, having a higher annual household income and age, having a larger social network, and displaying fewer COVID-19 prevention behaviors at phase 1. Further, the presence of potential alcoholism at phase 2 was predicted by being male, being more anxious, having a larger social network, exercising more, showing a deterioration of economic status, having more difficulties owing to a lack of daily necessities, having less healthy eating habits, and showing fewer COVID-19 prevention behaviors at phase 1. These findings suggest that psychological problems and increased work (or academic) and economic difficulties were associated with severe alcohol problems during a later stage of the COVID-19 pandemic.

Association of alcohol consumption and frequency with loneliness: A cross-sectional study among Japanese workers during the COVID-19 pandemic

Background

There are increasing concerns that prevention measures against coronavirus disease 2019 (COVID-19) such as social distancing and telework are leading to loneliness and poor lifestyle habits like increased alcohol consumption. The purpose of this study was to assess whether loneliness reported among workers during the COVID-19 pandemic is associated with changes in alcohol consumption.

Methods

The study comprised a cross-sectional, online survey of 27,036 workers between December 22 and 26, 2020. A questionnaire was used to assess loneliness, usual alcohol consumption and whether that consumption had changed. Odds ratios (ORs) were estimated by logistic regression analysis.

Results

A total of 2831 (10.5%) workers indicated they had increased alcohol consumption during the pandemic. Increased alcohol consumption was significantly associated with loneliness (OR = 1.94, 95%CI 1.70-2.21). This association held true for those who indicated they drank two or more days per week (OR = 1.98 95%CI 1.71-2.30) and those who drank less than one day per week (OR = 1.51 95%CI 0.71-3.25). In contrast, there was no association between increased alcohol consumption and loneliness among those who indicated they hardly ever drank (OR = 1.22 95%CI 0.55-2.72).

Conclusions

Among those drinking more than once a week, increased alcohol consumption is associated with loneliness.

Impact of COVID-19 lockdown on substance availability, accessibility, pricing, and quality: A multicenter study from India

BACKGROUND AND AIM

Pandemic and consequent lockdowns are likely to affect the drug market by the sudden disruption of the supply chain. We explored the change in the availability, access, purity, and pricing during lockdown from respondents seeking treatment for drugs, alcohol, and tobacco dependence.

MATERIALS AND METHODS

A cross-sectional survey was conducted among 404 respondents from seven treatment centers across India. A structured questionnaire assessed the change in availability, access, quality, and price of substances used during the first phase (March 24-April 14) and the second phase (April 15-May 3) of lockdown.

RESULTS

A majority of the respondents in treatment used tobacco (63%) and alcohol (52%). Relatively few respondents used opioids (45%) or cannabis (5%). Heroin (44%) was the most common opioid the respondents were treated for. Seventy-five percent, 65%, and 60% of respondents treated for alcohol, tobacco, and opioid problems, respectively, reported a reduction in the availability and access during the first phase of the lockdown. In the second phase, respondents with alcohol and tobacco dependence reported greater availability than those with opioid and cannabis dependence. The reported price of all substances increased more than 50% during the first phase of lockdown and remained higher throughout the second phase. Deterioration in purity was reported by more than half of the people who used opioid.

CONCLUSION

Lockdown could have affected both licit and illicit drug markets, albeit to a varying degree. The observed changes seemed short-lasting, as suggested by the recovering trends during the second phase of lockdown.

Do Differences in Drinking Attitudes and Alcohol-Related Problems Explain Differences in Sick Leave? A Multilevel Analysis of 95 Work Units Within 14 Companies From the WIRUS Study

Background

Systematic reviews have shown a strong relationship between alcohol consumption and sick leave. The effect of alcohol consumption on sick leave may, however, vary according to the work environment. While attitudes toward drinking may impact sick leave, there is little research on the contribution of drinking attitudes to sick leave. Moreover, alcohol-related problems and drinking attitudes may be influenced by the broader sociocultural contexts of the organizational units where people work.

Objectives

This study aimed to explore the relationship of alcohol-related problems and drinking attitudes with sick leave while considering the nesting of employees within working units within companies.

Method

Data from the WIRUS (Workplace Interventions preventing Risky alcohol Use and Sick leave) study were linked to company-registered sick leave data for 2,560 employees from 95 different work units in public (n = 9) and private companies (n = 5) in Norway. Three-level (employee, work unit, and company) negative binomial regression models were estimated to explore the 12-month prospective association of alcohol-related problems and drinking attitudes with four measures of sick leave (one-day, short-term, long-term, and overall sick leave days). Models were adjusted for gender, age, cohabitation status, educational attainment, work position, and employment sector.

Results

We observed higher variation of one-day, short-term, and overall sick leave days between companies than between work units within companies (15, 12, and 30% vs. 0, 5, and 8%, respectively). However, neither alcohol-related problems nor drinking attitudes were associated with sick leave and, thus, those variations in sick leave were not explained by alcohol-related problems or drinking attitudes.

Conclusion

Our findings suggest company-level differences are more important than within company differences when explaining differences in sick leave. While alcohol-related problems or drinking attitudes were not associated with sick leave, future studies may need to explore the role of company policies, practices, or social norms in variations in sick leave rates.

A Longitudinal Study on the Addictive Behaviors of General Population before and during the COVID-19 Pandemic in China

By using nationally representative longitudinal data, this study investigates the effects of the COVID-19 pandemic on the addictive behaviors (smoking and drinking) of the general population in China. From the China Family Panel Studies (CFPS) 2018 and 2020, we extract a sample of individuals over 16 years of age in China, consisting of 14,468 individuals and 28,936 observations. We decompose the sample into three age groups, that is, ages between 16 and 39, ages between 40 and 59 and ages above 60. The bootstrap method is used to estimate the confidence interval of the difference in the mean of addictive behaviors, and logit models are used in the regression analysis. Our results show that the COVID-19 pandemic reduces the smoking behavior of individuals above 40 years of age, and that it reduces the drinking behavior of individuals above 16 years of age. However, the pandemic increases the smoking behavior of individuals between 16 and 39 years of age. These results may be closely related to the characteristics of COVID-19 (that is, a respiratory system disease), the working and economic pressures of young Chinese and the role of drinking alcohol in building and maintaining social networks in China.

Alcohol use and the COVID-19 pandemic: Historical trends in drinking, contexts, and reasons for use among U.S. adults

Objective

The current study used U.S. national data to examine drinking trends prior to and during the COVID-19 pandemic in 2020, focusing on changes in U.S. young- and middle-adult alcohol prevalence, frequency, and drinking contexts and reasons, and whether they differed by age and college status.

Methods

Data from 2015 to 2020 from 16,987 young adults (ages 19–30) and 23,584 middle adults (ages 35–55) in the national Monitoring the Future study were used to model historical trends and potential 2020 shifts (data collection April 1 to November 30, 2020) in prevalence (30-day, daily, binge drinking) and frequency (30-day, binge drinking). For young adults, data on drinking contexts and negative affect reasons for drinking were examined. Moderation by age and college status was also tested.

Results

2020 was associated with (1) downward deviation in 30-day (young and middle adults) and binge drinking (young adults) prevalence; (2) upward deviation in daily drinking prevalence (middle adults); (3) among drinkers, upward deviation in frequency of 30-day (young and middle adults) and binge drinking (young adults); and (4) changes in drinking contexts and reasons among drinkers. Among college students, in particular, 2020 was associated with a downward deviation from expected historical trends in drinking prevalence. Upward deviations in daily prevalence and both binge and 30-day drinking frequency were stronger at ages 25–30 (vs. 19–24) and 35–45 (vs. 50–55).

Conclusions

Among U.S. young and middle adults, deviations from expected historical trends in population alcohol use that occurred during the pandemic included decreases in alcohol use prevalence, increases in alcohol use frequency, and increases in the use of alcohol to relax/relieve tension and because of boredom. These shifts were likely due, in part, to drinking while alone and at home—which increased during the pandemic.

Changes in alcohol use during the COVID-19 pandemic and previous pandemics: A systematic review

The objective of this study is to summarize the research on the relationships between exposure to the COVID-19 pandemic or previous pandemics and changes in alcohol use. A systematic search of Medline and Embase was performed to identify cohort and cross-sectional population studies that examined changes in alcohol use during or following a pandemic compared to before a pandemic occurred. Outcomes examined included differences in the volume and frequency of alcohol consumption and the frequencies of heavy episodic drinking (HED) and alcohol-related problems during a pandemic compared to before a pandemic. Quality assessment was performed using the Cochrane Risk of Bias Tool for Nonrandomized Studies. This study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search yielded 672 articles; 27 were included in the narrative review, of which 6 were cohort studies (all from high-income countries). A total of 259,188 participants were included. All cohort studies examined the impact of COVID-19 and associated pandemic-related policies, including social distancing and alcohol-specific policies, on alcohol use. Cohort studies demonstrated a consistent significant decrease in total alcohol consumption (Australia) and a significant increase in the frequency of alcohol use (United States). A significant decrease in the frequency of HED was observed in Australia and Spain but not in the United States. A significant increase in the proportion of people with problematic alcohol use was observed in the United Kingdom. Initial insights into changes in alcohol use indicate substantial heterogeneity. Alcohol use may have decreased in some countries, while HED and the proportion of people with problematic alcohol use may have increased. The lack of high-quality studies from low- and middle-income countries reflects a dearth of information from countries inhabited by most of the world's population.

Reduced alcohol consumption during the COVID-19 pandemic: Analyses of 17 000 patients seeking primary health care in Colombia and Mexico

Background

During the COVID-19 pandemic, an increase of heavy alcohol use has been reported in several high-income countries. We examined changes in alcohol use during the pandemic among primary health care (PHC) patients in two middle income countries, Colombia and Mexico.

Methods

Data were collected during routine consultations in 34 PHC centres as part of a large-scale implementation study. Providers measured patients’ alcohol consumption with the three item ‘Alcohol Use Disorders Identification Test’ (AUDIT-C). Generalized linear mixed models were performed to examine changes in two dependent variables over time (pre-pandemic and during pandemic): 1) the AUDIT-C score and 2) the proportion of heavy drinking patients (8+ on AUDIT-C).

Results

Over a period of more than 600 days, data from N = 17 273 patients were collected. During the pandemic, the number of patients with their alcohol consumption measured decreased in Colombia and Mexico. Each month into the pandemic was associated with a 1.5% and 1.9% reduction in the mean AUDIT-C score in Colombia and Mexico, respectively. The proportion of heavy drinking patients declined during the pandemic in Colombia (pre-pandemic: 5.4%, 95% confidence interval (CI) = 4.8% to 6.0%; during the pandemic: 0.8%, 95% CI = 0.6% to 1.1%) but did not change in Mexico.

Conclusions

Average consumption levels declined and the prevalence of heavy drinking patterns did not increase. In addition to reduced opportunities for social drinking during the pandemic, changes in the population seeking PHC and restrictions in alcohol availability and affordability are likely drivers for lower levels of alcohol use by patients in this study.

Employment, Economic, and Sociodemographic Factors Associated with Changes in Smoking and Drinking Behaviors during the COVID-19 Pandemic in South Korea

The societal disruptions resulting from the coronavirus disease 2019 (COVID-19) pandemic may have caused changes in smoking and alcohol consumption. Using data from the Koreans’ Happiness Survey, a nationally representative survey in South Korea, we (1) described population-level smoking and drinking behaviors; (2) assessed changes in smoking and drinking behaviors during the COVID-19 pandemic; and (3) identified employment, economic, and sociodemographic factors associated with these changes using multinomial logistic regression. The overall amount of smoking and drinking decreased during the pandemic, but the changes were heterogeneous across subgroups. Male gender, receipt of the basic living allowance, self-employment, unemployment, and chronic disease status were associated with increased smoking, while higher household income, temporary worker status, living with someone (versus alone), and having fewer offline friends were associated with decreased smoking. Male gender, self-employment, living alone, having more offline friends, and chronic disease status were associated with increased drinking, while younger age, male gender, low and high household income (i.e., a U-shaped relationship), long-term rent with a deposit, temporary worker status, and chronic disease status were associated with decreased drinking. Our findings provide evidence on changes in smoking and drinking during the COVID-19 pandemic in South Korea and differential changes across subgroups.

Changes in alcohol use during the COVID ‐19 pandemic in Europe: A meta‐analysis of observational studies

Issues

Numerous studies have examined the impact of the COVID‐19 pandemic on alcohol use changes in Europe, with concerns raised regarding increased use and related harms.

Approach

We synthesised observational studies published between 1 January 2020 and 31 September 2021 on self‐reported changes in alcohol use associated with COVID‐19. Electronic databases were searched for studies evaluating individual data from European general and clinical populations. We identified 646 reports, of which 56 general population studies were suitable for random‐effects meta‐analyses of proportional differences in alcohol use changes. Variations by time, sub‐region and study quality were assessed in subsequent meta‐regressions. Additional 16 reports identified were summarised narratively.

Key Findings

Compiling reports measuring changes in overall alcohol use, slightly more individuals indicated a decrease than an increase in their alcohol use during the pandemic [3.8%, 95% confidence interval (CI) 0.00–7.6%]. Decreases were also reported more often than increases in drinking frequency (8.0%, 95% CI 2.7–13.2%), quantity consumed (12.2%, 95% CI 8.3–16.2%) and heavy episodic drinking (17.7%, 95% CI 13.6–21.8%). Among people with pre‐existing high drinking levels/alcohol use disorder, high‐level drinking patterns appear to have solidified or intensified.

Implications

Pandemic‐related changes in alcohol use may be associated with pre‐pandemic drinking levels. Increases among high‐risk alcohol users are concerning, suggesting a need for ongoing monitoring and support from relevant health‐care services.

Conclusion

Our findings suggest that more people reduced their alcohol use in Europe than increased it since the onset of the pandemic. However high‐quality studies examining specific change mechanisms at the population level are lacking.

Self-reported changes in alcohol and tobacco use during COVID-19: findings from the eastern part of WHO European Region

Background

The COVID-19 pandemic might impact substance use behaviours around the globe. In this study, we investigate changes in alcohol and tobacco use in the second half of 2020 in countries of the eastern part of the WHO European Region.

Methods

Self-reported changes in alcohol and tobacco use among 11 295 adults from 18 countries in the eastern part of the WHO European Region were collected between August 2020 and January 2021. The non-probabilistic sample was weighted for age, gender and education. For each country, proportions of respondents reporting a decrease, no change or increase in substance use over the past 3 months were examined, and multinomial regression models were used to test associations with age, gender and past-year alcohol use.

Results

In most countries, about half of the respondents indicating past-year alcohol or tobacco use reported no change in their substance use. Of those alcohol users who reported changes in their alcohol use, a larger proportion reported a decrease than an increase in most countries. The opposite was true for tobacco use. Women, young adults and past-year harmful alcohol users were identified as being more likely to change their substance use behaviour.

Conclusion

We found diverging overall trends for alcohol and tobacco use in the second half of 2020. The patterns of change vary according to age, gender and past-year substance use. Individuals at risk to increase their substance use during the COVID-19 pandemic require most policy considerations.

Changes in Alcohol Use in Denmark during the Initial Months of the COVID-19 Pandemic: Further Evidence of Polarization of Drinking Responses

INTRODUCTION

The year 2020 was marked by the COVID-19 pandemic. Policy responses to COVID-19 affected social and economic life and the availability of alcohol. Previous research has shown an overall small decrease in alcohol use in Denmark in the first months of the pandemic. The present paper focused on identifying which subgroups of individuals had decreased or increased their consumption.

MATERIALS AND METHODS

Data were collected between May and July 2020 (n = 2,566 respondents, convenience sample). Weights were applied to reflect the actual Danish general population. Variables included the pre-pandemic alcohol consumption, change in alcohol consumption in the past month, socio-demographics, and reported economic consequences. Responses to a single item assessing changes in alcohol consumption in the past month were classified as no change, increase, or decrease in consumption. Regression models investigated how changes in consumption were linked to pre-pandemic drinking levels, socio-demographics (gender, age groups, education), and reported economic consequences.

RESULTS

While 39% of participants reported decreased consumption levels and 34% had stable levels, 27% increased consumption. Characteristics associated with changes in consumption were associated with both increases and decreases in consumption: younger people, those with higher consumption levels before the pandemic, and those with lower education more often both reported increases as well as decreases in consumption.

DISCUSSION/CONCLUSIONS

We confirmed that more people decreased rather than increased their alcohol consumption in the first few months of the pandemic in Denmark. Characteristics associated with changes in consumption such as younger age, higher consumption levels, and lower education demonstrated a polarization of drinking since these were associated with both increases and decreases in consumption. Public health authorities should monitor alcohol use and other health behaviours for increased risks during the pandemic.

Adolescents' Alcohol Use and Related Expectancies before and during the Early COVID-19 Pandemic: Evidence from the Nationwide MyLife Study

INTRODUCTION

We examined a range of alcohol use indicators among Norwegian adolescents before and during the early COVID-19 pandemic.

METHODS

We examined two cohorts of Norwegian 16-year-olds from the nationwide MyLife study who entered high school in fall 2020 (i.e., COVID-19 pandemic cohort; n = 915) and fall 2019/18 (i.e., prepandemic cohort; n = 1,621). Through e-surveys, adolescents reported their past year drinking frequencies and quantities (generating the Alcohol Use Disorders Identification Test-Concise; AUDIT-C scores) and completed Social Facilitation (SF) and Tension Reduction (TR) subscales of the Alcohol Outcome Expectancies Scale. Cohort differences across these outcomes were examined with linear and modified Poisson regression models.

RESULTS

There were no cohort differences in the proportion of adolescents who reported drinking in the past year or in drinking/binge drinking frequencies. However, alcohol quantities consumed on a typical drinking day were 1/3 of a drink greater in the COVID-19 cohort than in the prepandemic cohort; aIRR (95% CI) = 1.13 (1.02-1.25). These consumption differences compounded into significantly greater AUDIT-C scores (aIRR [95% CI] = 1.16 [1.02-1.32]) and positive AUDIT-C screens (31.2% vs. 26.4%; aRR [95% CI] = 1.21 [1.07-1.36]) in the COVID-19 cohort. In terms of alcohol-related expectancies, there were no SF differences, but the COVID-19 cohort reported significantly greater TR expectancies; b (95% CI) = 0.11 (0.02-0.20).

CONCLUSION

Despite the 2020 lockdown, Norwegian adolescents who started high school during the first pandemic year did not differ from their prepandemic peers in terms of how many of them drank, how often they drank, or in prosocial expectations they had of alcohol use. However, they consumed greater alcohol quantities per drinking day, had greater AUDIT-C scores, and reported greater tension reduction expectations of alcohol use. These results underscore the value of examining adolescents' alcohol-related behaviors during the COVID-19 pandemic above and beyond the basic drinking prevalence and frequencies.

Alcohol Use and Its Related Psychosocial Effects during the Prolonged COVID-19 Pandemic in Japan: A Cross-Sectional Survey

We conducted a large-scale survey in the Japanese population, about one year after the initial declaration of the state of emergency, to investigate alcohol use under the prolonged coronavirus disease 2019 (COVID-19) pandemic and its related psychosocial and demographic characteristics. The survey was conducted online between 15 and 20 June 2021. A total of 11,427 participants were included in the analysis (48.5% female, 48.82 ± 13.30 years, range = 20-90 years). Compared with females, males were more prevalent in the hazardous user and the potential alcoholism group and were less prevalent in the no alcohol-related problem group. However, the prevalence of potential alcoholism among the participants in our study was higher than that previously reported. This trend was particularly pronounced in women. The presence of potential alcoholism was related to a deteriorated psychological status, particularly depression and anxiety, and various difficulties in their daily lives due to the COVID-19 pandemic. In the future, intervention methods and systems should be developed to provide optimal assistance to people with psychological problems who are vulnerable to alcohol-related problems during the COVID-19 pandemic, while conducting further long-term follow-up studies.

Alcohol Consumption during the COVID-19 Lockdown Period: Predictors of At-Risk Drinking at Different AUDIT-C Cut-Off Thresholds

During the COVID-19 pandemic, alcohol consumption was largely confined to drinking in the home. There has been little research examining variables associated with risk in home drinking. The study employed an online survey of (n = 1128) individuals who had been recruited for their face recognition skills (n = 838, 70.9% females, mean age 45.05 (12.3 SD)). The main dependent variables were three different AUDIT-C cut-off scores for at-risk drinking: (a) 5 for both genders as recommended by Public Health England, (b) 7 for females and 8 for males (cut-off for students and young people) and (c) 8 for both genders (individuals seeking online help for their drinking). Among the independent variables were gender and age, motivations for home drinking using the Home Drinking Assessment Scale (HDAS), purchasing patterns, context of drinking and health and wellbeing. The predictors following hierarchical logistic regressions were for (a) purchasing alcohol online or at a supermarket and emotional HDAS scores, (b) purchasing alcohol online or at a supermarket and for parties, drinking alone and with other members of the household and emotional and practical reason HDAS scores, (c) as for b with the addition that men were more likely to be at-risk drinkers. At-risk drinking in the pandemic was explained by motivational reasons, purchasing patterns and situational factors.

Measuring changes in alcohol use in Finland and Norway during the COVID-19 pandemic: Comparison between data sources

OBJECTIVES

To examine (1) how a rapid data collection using a convenience sample fares in estimating change in alcohol consumption when compared to more conventional data sources, and (2) how alcohol consumption changed in Finland and Norway during the first months of the COVID-19 pandemic.

METHODS

Three different types of data sources were used for the 2nd quarter of 2020 and 2019: sales statistics combined with data on unrecorded consumption; the rapid European Alcohol Use and COVID-19 (ESAC) survey (Finland: n = 3800, Norway: n = 17,092); and conventional population surveys (Finland: n = 2345, Norway: n1 = 1328, n2 = 2189, n3 = 25,708). Survey measures of change were retrospective self-reports.

RESULTS

The statistics indicate that alcohol consumption decreased in Finland by 9%, while little change was observed in Norway. In all surveys, reporting a decrease in alcohol use was more common than reporting an increase (ratios 2-2.6 in Finland, 1.3-2 in Norway). Compared to conventional surveys, in the ESAC survey fewer respondents reported no change and past-year alcohol consumption was higher.

CONCLUSION

The rapid survey using convenience sampling gave similar results on change in drinking as conventional surveys but higher past-year drinking, suggesting self-selection effects. Aspects of the pandemic driving alcohol consumption down were equally strong or stronger than those driving it up.

Age and Living Situation as Key Factors in Understanding Changes in Alcohol Use during COVID-19 Confinement

(1) The aim of the present study was to evaluate and characterize changes in alcohol use during the COVID-19 confinement in a sample of Spanish adults, analyzing their age and living situation as defining life cycle variables. (2) Method: Data from 3779 individuals were collected through a set of online surveys. AUDIT-C was used to measure the frequency of consumption, the average daily consumption, intensive consumption, risky consumption, and Standard Drink Units. (3) Results: Although alcohol consumption during confinement showed a significant general decline, age revealed important differences, with the decline being more pronounced in adults from 18 to 29 years old. The living situation also showed significant differences. The largest decreases in alcohol consumption were found in those who lived with their parents or other relatives, whereas those who lived alone or with a partner even increased their level of consumption. In addition, the data show a significant interaction between these two variables and gender. (4) Conclusions: Age and cohabitation processes are key factors in understanding the life situation of each individual during confinement and, consequently, in explaining consumption patterns. The results obtained provide interesting recommendations for designing prevention policies in both normal and crisis circumstances, emphasizing the need to understand alcohol use from a psychosocial perspective.

Life in a time of COVID: a mixed method study of the changes in lifestyle, mental and psychosocial health during and after lockdown in Western Australians

BACKGROUND

Since the beginning of the COVID-19 pandemic, the Western Australian government imposed multiple restrictions that impacted daily life activities and the social life. The aim of this study was to examine the effects of COVID-19 lockdown on the community's physical, mental and psychosocial health.

METHODS

Approximately 2 months after a three-month lockdown, a cross-sectional study was opened to Western Australian adults for an 8-week period (25th August - 21 October 2020). Participants competed a 25-min questionnaire adapted from the Western Australia Health and Wellbeing Surveillance system. Participants provided information on their socio-demographic status, lifestyle behaviours, mental health, and psychosocial health during and post-lockdown. Open-ended questions explored key issues in greater detail. Changes between the lockdown and post-lockdown period were assessed using Wilcoxon signed rank test and One-Sample Kolmogorov-Smirnov Normal tests as appropriate. Sex differences were examined using the Mann-Whitney U test. A content analysis approach examined responses to the open-ended questions with frequencies and variations in responses determined using Chi-Square tests.

RESULTS

A total of 547 complete responses were obtained. Compared to post-lockdown period, lockdown was associated with a significantly lower levels of physical activity, poorer mental well-being and sense of control over one's life, and a higher level of loneliness. Similarly, during lockdown, there was a significantly higher consumption of junk food, soft drinks and alcoholic drinks but no change in fruit and vegetable intake. Participants recalled health campaigns on hand washing and social distancing and there was a retrospective view that more timely and informative campaigns on physical activity, nutrition and mental well-being should have been available during lockdown.

CONCLUSIONS

While advice on infection control measures were appropriately provided, there is a need for concurrent health promotional information to help combat the changes in physical, mental and psychosocial well-being observed during quarantine to prevent negative health consequences in the community even if there are minimal effects of the pandemic itself.

Changes in Alcohol Consumption during the COVID-19 Pandemic Are Dependent on Initial Consumption Level: Findings from Eight European Countries

Evidence suggests that changes in alcohol consumption during the first months of the COVID-19 pandemic were unevenly distributed over consumer groups. We investigated possible inter-country differences in how changes in alcohol consumption are contingent on initial consumption (before or at the start of the pandemic), and how changes in consumption translate into possible changes in the prevalence of heavy drinking. We used data from the European Survey on Alcohol use and COVID-19 (ESAC) conducted in Czechia, Denmark, Finland, Germany, Norway, Poland, Spain, and the UK (N = 31921). Past-year alcohol consumption and changes in consumption were measured by AUDIT-C. Drinking habits were compared according to percentiles of pre-pandemic consumption levels, below versus above the 90th percentile. Across countries, drinkers in the highest 10% for pre-pandemic consumption increased their drinking during the pandemic, whereas absolute changes among those initially drinking below this level were modest. The percentage of people reporting >28 alcohol units/week increased significantly in seven of eight countries. During the first months of the COVID-19 pandemic, alcohol consumption in the upper decile of the drinkers increased as did the prevalence of heavy drinkers, in contrast with a declining consumption in other groups in the sample.

Is talk cheap? Correspondence between self-attributions about changes in drinking and longitudinal changes in drinking during the coronavirus disease 2019 pandemic

Background

There are concerns that the coronavirus disease 2019 (COVID‐19) pandemic may increase drinking, but most accounts to date are cross‐sectional studies of self‐attributions about alcohol‐related impacts and the accuracy of those perceptions has not been investigated. The current study examined the correspondence between self‐attributions of pandemic‐related changes in drinking and longitudinally‐measured changes in drinking and alcohol‐related consequences in a sample of emerging adults.

Methods

In an existing ongoing longitudinal study on alcohol misuse (≥1 heavy episodic drinking day/month) in emerging adults, 473 individuals (M_age = 23.8; 41.7% male) received a supplemental assessment from June 17th to July 1st, 2020, during public health restrictions in Ontario, Canada. These intrapandemic data were matched to the most recent assessment prior to the pandemic (~8 months earlier). Self‐attributions about changes in drinking were assessed globally (i.e., increases/decreases/no change) and with higher resolution questions clarifying the magnitude of changes.

Results

Global self‐attributions about changes in drinking substantively paralleled longitudinal changes in weekly drinking days (DD). In the longitudinal data, individuals’ who self‐reported increases in drinking exhibited significant increases; individuals’ who self‐reported decreases exhibited significant decreases; and individuals who self‐reported no change exhibited nonsignificant changes. Higher resolution items likewise revealed longitudinal patterns of weekly drinking that were substantively consistent with self‐attributions. Heavy DD and alcohol‐related consequences exhibited similar patterns, but only individuals who self‐reported large increases in drinking exhibited increases on these outcomes. Individuals who reported large increases in drinking also exhibited significant increases in depression and posttraumatic stress disorder symptoms.

Conclusions

Self‐attributions about drinking closely corresponded to longitudinal changes in drinking, supporting the validity of self‐attributions in population‐level surveys, particularly in young adults. Notably, a subgroup was identified that exhibited pronounced increases for all alcohol‐related outcomes and concurrent increases in internalizing psychopathology.

Acute effect of the COVID-19 pandemic on emergency transportation due to acute alcoholic intoxication: a retrospective observational study

Background

The COVID-19 pandemic has caused changes in people’s drinking habits and the emergency management system for various diseases. However, no studies have investigated the pandemic’s impact on emergency transportation for acute alcoholic intoxication. This study examines the effect of the pandemic on emergency transportation due to acute alcoholic intoxication in Kochi Prefecture, Japan, a region with high alcohol consumption.

Methods

A retrospective observational study was conducted using data of 180,747 patients from the Kochi-Iryo-Net database, Kochi Prefecture’s emergency medical and wide-area disaster information system. Chi-squared tests and multiple logistic regression analyses were performed. The association between emergency transportation and alcoholic intoxication was examined. The differences between the number of transportations during the voluntary isolation period in Japan (March and April 2020) and the same period for 2016–2019 were measured.

Results

In 2020, emergency transportations due to acute alcoholic intoxication declined by 0.2%, compared with previous years. Emergency transportation due to acute alcoholic intoxication decreased significantly between March and April 2020, compared with the same period in 2016–2019, even after adjusting for confounding factors (adjusted odds ratio 0.67; 95% confidence interval 0.47–0.96).

Conclusions

This study showed that lifestyle changes due to the COVID-19 pandemic affected the number of emergency transportations; in particular, those due to acute alcoholic intoxication decreased significantly.

Working at home and alcohol use

•

The use of own home as a workplace is increasing.

•

Working at home is associated with higher alcohol consumption.

•

Working at home may facilitate alcohol use that otherwise would not happen.

Working at home has become a frequent work arrangement following the COVID-19 pandemic. However, little is known about how working at home influence alcohol use among employees. This study examines associations between working at home at least 15 h per week and alcohol consumption using data from a pre-COVID-19 sample. Self-reported questionnaire data on working at home and alcohol use from a large cross-sectional sample of Norwegian employees (N = 14,728). Data were collected between 2004 and 2019 and were analyzed by ordinal logistic regressions. Working at home for >15 h per week was significantly associated with alcohol use (OR 1.67, 95% CI: 1.30 – 2.16). The association remained significant after adjusting for age, gender, leadership position, and educational level. Working at home may facilitate alcohol use that otherwise would not happen. Organizations must ensure that policies and procedures are in place to prevent alcohol use during working hours among employees working at home.

Sociodemographic changes in emergency department visits due to alcohol during COVID-19

INTRODUCTION

Little detailed sociodemographic information is available about how alcohol use and associated health care visits have changed during COVID-19. Therefore, we assessed how rates of emergency department (ED) visits due to alcohol have changed during COVID-19 by age and sex and for individuals living in urban and rural settings and low and high-income neighborhoods.

METHODS

Our cohort included 13,660,516 unique Ontario residents between the ages of 10-105. We compared rates and characteristics of ED visits due to alcohol, identified using ICD-10 codes, from March 11-August 31 2020 to the same period in the prior 3 years. We used negative binomial regressions to examine to examine changes is visits during COVID-19 after accounting for temporal and seasonal trends.

RESULTS

During COVID-19, the average monthly rate of ED visits due to alcohol decreased by 17.2 % (95 % CI -22.7, -11.3) from 50.5-40.9 visits per 100,000 individuals. In contrast, the proportion of all-cause ED visits due to alcohol increased by 11.4 % (95 % CI 7.7, 15.3) from 15.0 visits to 16.3 visits per 1000 all cause ED visits. Changes in ED visits due to alcohol were similar for men in women. Decreases in visits were larger for younger adults compared to older adults and pre-COVID-19 disparities in rates of ED visits due to alcohol between urban and rural settings and low and high-income neighborhoods widened. ED visits related to harms from acute intoxication showed the largest declines during COVID-19, particularly in younger adults and urban and high-income neighborhoods.

CONCLUSION

ED visits due to alcohol decreased during the first six months of COVID-19, but to a lesser extent than decreases in all-cause ED visits. Our data suggest a widening of geographic and income-based disparities in alcohol harms in Ontario during COVID-19 which may require immediate and long-term interventions to mitigate.

Problematic Use of Alcohol and Online Gaming as Coping Strategies During the COVID-19 Pandemic: A Mini Review

The COVID-19 (coronavirus disease 2019) pandemic has dramatically changed our daily lives and activities, including those originally intended to serve for leisure and pleasure. Drinking and online gaming became coping behaviors used to rescue ourselves from the stress and restricted lifestyle during the COVID-19 pandemic. However, frequent drinking and gaming can result in the pathological consequences of addiction. Those affected use the stimuli not to obtain pleasure, but rather to avoid the displeasure induced by stress and previous use, often unsuccessfully. This review aims to provide an overview of recent longitudinal cohort studies on alcohol and gaming use during the COVID-19 pandemic, as well as to analyze how the pandemic has affected alcohol and gaming use. There was a substantial risk of alcohol and online gaming overuse during the lockdown, which may depend on the pandemic's duration or overuse patterns. Previous studies have shown that increased alcohol consumption and online gaming are associated with heightened stress and anxiety levels caused by social isolation/quarantine. Over time, frequent or excessive alcohol consumption and gaming could lead to an increased risk of more serious mental health problems. Every effort should be made to mitigate mental health problems and ensure adequate adaptation to these exceptional circumstances. Therefore, it would be helpful to encourage physical activity, social interaction, and collaboration to facilitate psychological and physical health.
