Binge drinking in Japan during the COVID-19 pandemic: Prevalence, correlates and association with preventive behaviors

Beyond Confinement: A Systematic Review on Factors Influencing Binge Drinking Among Adolescents and Young Adults During the Pandemic

Objectives: This study aimed to enhance the understanding of factors influencing changes in binge drinking (BD) behavior during the COVID-19 pandemic, with a particular focus on its impact on the health of individuals aged 12 to 25 years. Methods: A systematic review was conducted, encompassing studies published between January 2020 and September 2024. Articles were retrieved from PubMed, Web of Science, and Scopus, following PRISMA guidelines and the Joanna Briggs Institute (JBI) review protocols. Inclusion criteria targeted studies focusing on BD during the COVID-19 pandemic in adolescents or school-aged individuals without specific medical conditions. Exclusions included studies limited to a single gender, ethnicity, or profession, as well as doctoral theses and editorials. JBI tools were used to assess the quality of the selected studies. Results: From 33 studies (19 cross-sectional and 14 longitudinal), trends in BD during the pandemic varied: 2 studies reported an increase, while 21 indicated a decrease. Key factors linked to increased BD included pandemic stressors (e.g., isolation, social disconnection and non-compliance with restrictions), psychosocial issues (e.g., depression, anxiety, boredom, and low resilience), prior substance use, and sociodemographic variables (e.g., low education, economic extremes, living arrangements, and limited family support). Female gender and academic disengagement were also risk factors. Conversely, factors like stay-at-home orders, fear of contagion, family support, studying health sciences, and resilient coping strategies contributed to reduced BD. Other variables, such as pandemic stress and self-efficacy, had inconsistent effects. Conclusions: Factors contributing to increased BD included pandemic-related stress, mental health conditions, and unhealthy habits, while protective factors included stay-at-home orders, social support, and resilient coping. The study highlights the need for effective prevention and intervention strategies, emphasizing a holistic approach in healthcare, early detection, and tailored interventions, particularly for vulnerable groups such as adolescents.

Long-term health consequences and costs of changes in alcohol consumption in England during the COVID-19 pandemic

BACKGROUND AND AIMS

The COVID-19 pandemic led to changes in alcohol consumption in England. Evidence suggests that one-fifth to one-third of adults increased their alcohol consumption, while a similar proportion reported consuming less. Heavier drinkers increased their consumption the most and there was a 20% increase in alcohol-specific deaths in England in 2020 compared with 2019, a trend continuing through 2021 and 2022. This study aimed to quantify future health, healthcare, and economic impacts of changes in alcohol consumption observed during the COVID-19 pandemic.

METHODS

This study used a validated microsimulation model of alcohol consumption and health outcomes. Inputted data were obtained from the Alcohol Toolkit Study, and demographic, health and cost data from published literature and publicly available datasets. Three scenarios were modelled: short, medium, and long-term, where 2020 drinking patterns continue until the end of 2022, 2024, and 2035, respectively. Disease incidence, mortality, and healthcare costs were modelled for nine alcohol-related health conditions. The model was run from 2020 to 2035 for the population of England and different occupational social grade groups.

RESULTS

In all scenarios, the microsimulation projected significant increases in incident cases of disease, premature mortality, and healthcare costs, compared with the continuation of pre-COVID-19 trends. If COVID-19 drinking patterns continue to 2035, we projected 147,892 excess cases of diseases, 9,914 additional premature deaths, and £1.2 billion in excess healthcare costs in England. The projections show that the more disadvantaged (C2DE) occupational social grade groups will experience 36% more excess premature mortality than the least disadvantaged social group (ABC1) under the long-term scenario.

CONCLUSIONS

Alcohol harm is projected to worsen as an indirect result of the COVID-19 pandemic and inequalities are projected to widen. Early real-world data corroborate the findings of the modelling study. Increased rates of alcohol harm and healthcare costs are not inevitable but evidence-based policies and interventions are required to reverse the impacts of the pandemic on alcohol consumption in England.

Greater impact of COVID-19 on peer-supported addiction services than government-owned services for addiction in Japan: A nationwide 3-year longitudinal cohort study

Aim

This study aims to investigate how the coronavirus disease (COVID-19) pandemic impacted service provision of peer-supported addiction services, such as self-help groups or recovery houses and government-owned addiction healthcare services, in Japan, as well as the quality of their interaction.

Methods

An online survey was distributed to all 69 public regional healthcare facilities (Mental Health and Welfare Centers [MHWCs]) across the 47 prefectures of Japan annually from 2021 to 2023, totaling three surveys. The survey asked about: (1) the current status of addiction healthcare services at each center, (2) the current status of peer-supported addiction services within each center's area, and (3) changes in connectivity between centers and peer-supported addiction services.

Results

All 69 centers participated in the survey each year. Following the second year of the pandemic, both MHWCs and peer-supported services experienced service closures and restrictions; however, peer-supported services were notably more affected nationwide, such as downsizing of services, decreased number of users, shortage of operation funds, and inability to connect with other services being widely reported (p < 0.0001). Despite the easing of most restrictions by the fourth year, MHWCs in 18 out of 47 prefectures reported at least one sustained negative impact on their service provision, while peer-supported services struggled to recover, with 40 out of 47 prefectures still observing difficulties.

Conclusion

The COVID-19 pandemic significantly affected both types of service, with peer-supported services facing greater challenges in recovery. Additional support is essential to restore these services to normal operation.

Psychotic-like experiences and problem drinking among adults in Japan

BACKGROUND

Psychotic-like experiences (PLEs) are common in the general population and have been linked to alcohol misuse and abuse. However, much of this research has been undertaken in Western countries. To address this deficit, the current study examined the association between PLEs and problem drinking in the Japanese general population.

METHODS

Data were used from 3717 adults (age 18-89) collected in an online survey in 2023. Information was obtained on PLEs with the PRIME Screen-Revised (PS-R), while problem drinking was assessed with the CAGE questionnaire (where a score of ≥ 2 was used to categorize cases). Logistic regression was used to examine the associations.

RESULTS

Problem drinking was prevalent in the study sample (12.5%). In an analysis that was adjusted for sociodemographic factors, self-rated health, smoking status and depressive symptoms, PLEs were associated with significantly higher odds for problem drinking in the total sample (OR: 1.70, 95%CI: 1.13-2.55). In a sex-stratified analysis PLEs were not linked to problem drinking in men (OR: 1.16, 95%CI 0.68-2.00), whereas women with PLEs had over 2.8 times higher odds for problem drinking (OR: 2.83, 95%CI: 1.54-5.21).

CONCLUSION

PLEs are associated with problem drinking in the Japanese general population and this association is especially pronounced in women. As problem drinking has been linked to a number of detrimental outcomes, future research should examine the potential effects of problem drinking in individuals with PLEs.

Association of lifestyle and flourishing during the COVID-19 pandemic in Japan

Introduction

COVID-19 have changed our lifestyle and little is known how our lifestyle associated with flourishing during COVID-19. This study examined the association between lifestyle, including sleep time, drinking, and smoking, and flourishing during the COVID-19 pandemic in Japan.

Methods

We used the population-based study, Utsunomiya COVID-19 seROprevalence Neighborhood Association (U-CORONA) survey conducted in November 2021 to examine the association between lifestyle such as sleeping time, drinking and smoking, and flourishing (n = 473). Flourishing was assessed with the flourishing index, a 10-item multidimensional scale with five domains. Multivariate linear regression analysis was performed adjusted for sex, age, income, and education.

Results

We found that the flourishing index was significantly lower in the group that slept less than 6 h than in the group that slept 6-8 h (coef = -0.49, SE = 0.17, p < 0.01). We also found that drinking once to several times/week showed higher flourishing than those who almost never drink (coef = 0.57, SE = 0.19, p < 0.01). Smoking was not associated with flourishing.

Discussion

Sleep duration and drinking habit, but not smoking, may be important for flourishing during the COVID-19 pandemic.

Changes in the frequency and amount of alcohol intake before and during the COVID-19 pandemic

OBJECTIVES

Concerns have been raised regarding the impact of the COVID-19 pandemic on alcohol consumption patterns, which can have implications for public health. In this descriptive study, we aimed to show the change in the frequency and amount of alcohol consumption in Japan before and during the COVID-19 pandemic periods.

METHODS

We analyzed data from annual health checkups among Japanese workers from April 2018 to March 2021. Changes in the frequency (daily, occasionally, rarely/never) and amount per one-time (4 categories by Japanese alcohol unit) of alcohol consumed among 331 200 participants were summarized by sex as 1-year changes in the periods before (fiscal year [FY] 2018 to FY 2019) and during (FY 2019 to FY 2020) the COVID-19 pandemic.

RESULTS

Among daily drinkers and rarely/never drinkers, overall, 1-year changes in the frequency of alcohol consumption during the pandemic were mostly consistent with changes before the pandemic, for both sexes. The number of occasional drinkers who drank less frequently a year later increased during the pandemic compared with before the pandemic (from 9.6% to 11.6% among men and from 12.9% to 16.5% among women); however, occasional drinkers who drank more frequently showed a small increase. Collectively, both men and women showed a slight decrease in both the frequency and amount of alcohol consumption during the pandemic among occasional drinkers.

CONCLUSIONS

No major shifts in alcohol consumption habits occurred during the pandemic in our study population. Occasional drinkers tended to drink less during the pandemic, suggesting that initial concerns about increased alcohol consumption owing to the pandemic were unfounded.

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.

Change of human flourishing during the COVID-19 pandemic in Japan: Results from population-based U-CORONA study

Longitudinal change in flourishing during the pandemic of COVID-19 would provide new insight to reveal determinants of well-being. We aimed to describe changes in flourishing during the COVID-19 pandemic in Japan and to examine the association of sex, age, education, and income with changes in flourishing. Utsunomiya COVID-19 seROprevalence Neighborhood Association (U-CORONA) study conducted in October 2020 and November 2021 was used (n = 419 in 2020 and n = 478 in 2021, and n = 327 for both waves). Flourishing was assessed using a 12-item multidimensional flourishing scale including six domains. Change of flourishing was categorized into decreased, unchanged, and increased. Multinomial logistic regression was applied to longitudinal data to estimate the relative risk ratio of increase and decrease in flourishing scores. Cross-sectional analysis showed that the mean score of flourishing was approximately seven in both waves, with no sex differences, but older adults had higher scores than young-aged adults. We found that men were twice as likely to lose their flourishing scores as women and lower levels of education were associated with 2-3 times declining flourishing scores than higher levels of education. Age and income were not significantly associated with the change of flourishing. During the COVID-19 pandemic, flourishing declined, and men and lower-educated people were more vulnerable. In prolonged difficult situations, support for men and less educated people may contribute to the prevention of declining well-being in Japan.

Is There an Association between Being a Victim of Physical Violence by Intimate Partner and Binge Drinking in Men and Women? Secondary Analysis of a National Study, Peru 2020

The relationship between being a victim of physical violence by an intimate partner and binge drinking (BD) is a poorly explored line of research, especially in men. To determine the association between being a victim of physical violence by an intimate partner and BD in men and women in Peru in 2020, a secondary analytical cross-sectional study was conducted using the Demographic Health Survey. BD was categorized according to the Center of Disease Control definition for men and women, based on the type and amount of alcoholic beverage ingested. Physical violence was based the report of being hit with any part of the body or an object, by their intimate partner. To identify the association, a multivariable general linear model of the family and link log Poisson was used. The results were presented as prevalence ratios (PRs). In the adjusted models stratified by sex, a 90% greater likelihood of BD was found in male victims and an 80% higher probability among female victims (PRa 1.9, 95%CI 1.3;2.7, p < 0.001 vs. PRa 1.8, CI95% 1.1; 2.8, p = 0.013, respectively). An association was found between physical violence by an intimate partner and BD in the Peruvian population older than 15 years, in both men and women.
