Longitudinal assessment of drinking changes during the pandemic: The 2021 COVID-19 follow-up study to the 2019 to 2020 National Alcohol Survey

Long-term trends in beverage-specific drinking in the National Alcohol Surveys: Differences by sex, age, and race and ethnicity

BACKGROUND

Despite substantial declines in underage drinking and binge drinking, alcohol consumption has increased in the past 30 years. This study examined how beverage-specific drinking patterns varied by sex, age, and race and ethnicity from 1979 to 2020.

METHODS

Secondary data analysis was conducted on pooled data from the National Alcohol Survey series from 1979 to 2020 of a sample of U.S. adults ages 18 years or older. Total and beverage-specific volume were calculated from graduated frequency questions on reported beverage type, which included beer, wine, and spirits. Sex-stratified analyses focused on descriptive trends of each alcohol measure over time and by age and race and ethnicity. Time-varying effect models were also conducted to identify subgroups at higher risk for increased consumption over time.

RESULTS

Women's drinking increased, with alcohol volume rising substantially from 2000 to 2020; the largest increase was among women 30 and older. Men's alcohol volume also rose over this period but remained below the levels of 1979 and 1984, with older adults increasing their consumption those 18-29 decreased their drinking. Beverage-specific trends showed some similarities by gender: in 2020, wine volume was at its highest level for both women and men, while spirits volume also was at its highest level for men and in women was tied with the 1979 peak in spirits consumption. Increases were also found among Black men and women and Latina women from 2000 to 2020.

CONCLUSIONS

Given the increases in alcohol volume, particularly among women and older age groups, alcohol policy, interventions, and education should consider ways to reduce harms associated with alcohol use among these groups. Continued monitoring of beverage-specific drinking patterns is needed to track policy-relevant changes.

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.

Challenges and Implications for Substance Use and Mental Healthcare Among Under-Resourced Women in the COVID-19 Era

BACKGROUND

The COVID-19 pandemic exacerbated disparities in mental healthcare and substance use disorder (SUD) treatment access, especially in under-resourced communities. This study aimed to comprehend the experiences of under-resourced women with SUD during the pandemic, their knowledge and attitudes toward it, and its impact on substance use and treatment access.

METHODS

A cross-sectional study included 66 under-resourced women receiving medically managed withdrawal treatment at a community residential SUD center. Data collection occurred between November 2021 and August 2022, utilizing a 75-item instrument covering COVID-19 exposure and its impact on health, substance use, treatment access, vaccination status, beliefs, and knowledge. Descriptive analyses summarized the data.

RESULTS

Participants faced various challenges during the pandemic. Many reported increased substance use, especially alcohol, opioids, benzodiazepines, and nicotine. Mental health stability was negatively affected, exacerbating existing disorders and limiting mental healthcare access. A majority (56.1%) reported that their chronic mental health disorder was less stable during the pandemic. Twenty (30.3%) participants reported that they had been diagnosed with a new mental health disorder since the pandemic, and 28.8% reported that it was harder for them to access mental healthcare during the pandemic. Job loss, housing instability, and financial strain were prevalent. Half (n=33, 50%) received a COVID-19 vaccine dose, while 27.3% (n=18) declined vaccination due to knowledge gaps and religious beliefs. The majority (n=41, 62.1%) worried about securing basic needs such as groceries and medication, with 64.6% (n=42) expressing a desire to cope using alcohol or drugs.

CONCLUSIONS

This study expands upon previous research by examining the effect of the COVID-19 pandemic on mental health in the context of substance use disorder treatment. Unlike previous data, which focused solely on substance use behaviors, our study delves into the impact of the pandemic on co-occurring mental health disorders. Findings underscore the need for gender-responsive and culturally appropriate SUD treatment. Vaccine hesitancy, as reflected in the study, necessitates more effective, tailored evidence-based informational campaigns. Efforts must focus on enhancing mental healthcare access, reducing stigma, and supporting individuals with co-occurring conditions amidst this evolving COVID-19 health crisis.

Association between sociodemographics and change in alcohol or tobacco use behaviors during the COVID-19 pandemic

OBJECTIVE

To examine the association between various sociodemographic factors with alcohol and tobacco use behaviors during the COVID-19 pandemic.

METHODS

Participants from Ohio and Indiana were asked to participate in the 'Impact of COVID-19 on the Cancer Continuum Consortium' study (N = 32,989) from June-November 2020. Those who completed the survey and responded to key study questions were included (n = 5,374). Participants were asked about the frequency and type of alcohol and tobacco product used. Multivariable logistic regression was conducted to determine factors associated with the impact of COVID-19 on change in alcohol and/or tobacco use.

RESULTS

Mean age was 57 years old, 68% were female, 90% non-Hispanic white, 75% married, and 31% lived in rural counties. Out of 5,374 participants, 53% used alcohol-only (n = 2,833), 5% used tobacco-only (n = 255), 7% used both alcohol and tobacco (n = 395), and 35% used neither alcohol nor tobacco (n = 1,891). Urban county of residence (vs. rural) was associated with an increase in alcohol-use (p = 0.0001), change in alcohol products (p = 0.023), and an increase in tobacco use (p = 0.05). Among alcohol-only users, those who were younger (OR = 0.97), female (OR = 1.58), married (OR = 1.69), of high socioeconomic status (OR = 1.99), residing in urban counties (OR = 1.65), and had elevated financial (OR = 1.06) and employment concerns (OR = 1.28) were significantly more likely to report increased alcohol-use. Similarly, among tobacco users, those who were younger (OR = 0.97), female (OR = 2.79), married (OR = 2.16) or divorced (OR = 2.83), and had higher levels of neighborhood disadvantage (OR = 2.19) were significantly more likely to report increased tobacco-use.

CONCLUSIONS

Findings suggest targeted intervention and prevention strategies for young, female participants with elevated financial and employment concerns during the COVID-19 pandemic are necessary to mitigate risks associated with higher odds of alcohol and tobacco use. Our findings on alcohol and tobacco use may be a result of the unique social and economic influence of the pandemic on women.

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.

Risk estimation in relation to anxiety and depression for low probability negative events

Foundational cognitive models propose that people with anxiety and depression show risk estimation bias, but most literature does not compute true risk estimation bias by comparing people's subjective risk estimates to their individualized reality (i.e., person-level objective risk). In a diverse community sample (N = 319), we calculated risk estimation bias by comparing people's subjective risk estimates for contracting COVID-19 to their individualized objective risk. Person-level objective risk was consistently low and did not differ across symptom levels, suggesting that for low probability negative events, people with greater symptoms show risk estimation bias that is driven by subjective risk estimates. Greater levels of anxiety, depression, and COVID-specific perseverative cognition separately predicted higher subjective risk estimates. In a model including COVID-specific perseverative cognition alongside anxiety and depression scores, the only significant predictor of subjective risk estimates was COVID-specific perseverative cognition, indicating that symptoms more closely tied to feared outcomes may more strongly influence risk estimation. Finally, subjective risk estimates predicted information-seeking behavior and eating when anxious, but did not significantly predict alcohol or marijuana use, drinking to cope, or information avoidance. Implications for clinical practitioners and future research are discussed.

Bed Nucleus of the Stria Terminalis (BNST) neurons containing the serotonin 5HT2c receptor modulate operant alcohol self-administration behavior in mice

The serotonin 5HT2c receptor has been widely implicated in the pathophysiology of alcohol use disorder (AUD), particularly alcohol seeking and the affective consequences of chronic alcohol consumption. However, little is known about the brain sites in which 5HT2c exerts its effects on specific alcohol-related behaviors, especially in females. Here, we investigated the effects of site-specific manipulation of the 5HT2c receptor system in the BNST on operant alcohol self-administration behaviors in adult mice of both sexes, including the acquisition and maintenance of fixed-ratio responding, motivation for alcohol (progressive ratio), and quinine-adulterated responding for alcohol on a fixed-ratio schedule (punished alcohol seeking). Knockdown of 5HT2c in the BNST did not affect the acquisition or maintenance of operant alcohol self-administration, nor did it affect progressive ratio responding for alcohol. This manipulation had only a subtle effect on responding for quinine alcohol selectively in females. On the other hand, chemogenetic inhibition of BNST 5HT2c-containing neurons (BNST5HT2c) increased operant alcohol self-administration behavior in both sexes on day 2, but not day 9, of testing. It also increased operant responding for 1000 μM quinine-adulterated alcohol selectively in males. Importantly, chemogenetic inhibition of BNST5HT2c did not alter operant sucrose responding or motivation for sucrose in either sex. We then performed cell-type specific anterograde tracing, which revealed that BNST5HT2c project to similar regions in males and females, many of which have been previously implicated in AUD. We next used chemogenetics and quantification of the immediate early gene cFos to characterize the functional influence of BNST5HT2c inhibition on vlPAG activity. We show that chemogenetic inhibition of BNST5HT2c reduces vlPAG cFos in both sexes, but that this reduction is more robust in males. Together these findings suggest that BNST5HT2c neurons, and to a small extent the BNST 5HT2c receptor, serve to promote aversive responses to alcohol consumption, potentially through sex-dependent disinhibition of vlPAG neurons.

Between-hospital care referrals for severe alcohol-related liver disease during the COVID-19 pandemic, 2020 to 2022

Increased alcohol consumption during the coronavirus disease 2019 pandemic is projected to impact alcohol-related liver disease (ALD) morbidity and mortality. Inter-hospital escalation-of-care referral requests to our tertiary-care hepatology unit were analyzed from January 2020 through December 2022. Most requests to our center were for ALD with an increase in requests from intermediate care units, suggestive of higher acuity illness.

Disparities in Alcoholics Anonymous Participation from 2000 to 2020 Among U.S. Residents With an Alcohol Use Disorder in the National Alcohol Survey

OBJECTIVE

Mutual-help groups (MHGs) like Alcoholics Anonymous (AA) are effective for resolving alcohol use disorders (AUDs), but few studies have examined disparities in MHG participation, particularly recently. We used five waves of National Alcohol Survey data to investigate whether prevalence of AA attendance among those with a lifetime AUD differed by race/ethnicity, age, and sex, directly testing whether these associations varied with time.

METHOD

Analyses pooled weighted data from 2000 to 2020, including only participants with a lifetime AUD and identifying as non-Hispanic White, Latinx/Hispanic, or non-Hispanic Black/African American (N = 8,876). Logistic regression models examined associations between lifetime AA attendance and survey year, race/ethnicity, age, and sex; models also tested for differences in demographic effects across survey year using interaction terms.

RESULTS

In bivariate models, AA attendance was significantly less prevalent among participants identifying as Latinx/Hispanic (vs. White); ages 18-29 (vs. 30-64); and female (vs. male). Survey year was unrelated to AA attendance, and all interactions involving survey year were nonsignificant. In the final multivariate model (which controlled for severity and other help-seeking), disparities persisted for those identifying as Latinx/Hispanic (vs. White; adjusted odds ratio [aOR] = 0.63) and ages 18-29 (vs. 30-64; aOR = 0.35); AA attendance was also less prevalent among Black/African American (vs. White) participants (aOR = 0.59), but sex became nonsignificant.

CONCLUSIONS

Results replicate and extend sparse findings regarding disparities in MHG attendance and suggest a stagnation in AA's growth and reach to underserved populations. Findings highlight the need to more effectively facilitate MHG attendance (and perhaps broader social network change) among racial/ethnic minorities and emerging adults.

The risk of developing dementia in the COVID-19 pandemic; a cohort study

OBJECTIVES

The effects of the COVID-19 pandemic on cognitive decline are not fully understood. Higher social activity and relationships have been associated with decreased risk of dementia. We hypothesised that risk of transition to dementia would increase after the start of the first national lockdown.

METHODS

We obtained data from the Brains for Dementia (BDR) cohort, which has collected roughly annual data on 3726 older adults with and without dementia since 2008. Data continued to be collected during the lockdowns, although by telephone and/or video call instead of in person. Individuals diagnosed with dementia at study entry were excluded from this study as were individuals with only one visit. Cognitive status was classified using the Clinical Dementia Rating (CDR) global score. Poisson regression with cubic splines to account for differences in age was used to compare the incidence of dementia before and after March 1st 2020.

RESULTS

Out of 2242 individuals, 208 individuals developed dementia before and 50 developed dementia after 01/03/20. The incidence rate ratio of developing dementia after 01/03/20 was 0.847 (0.538-1.335) p = 0.570. In our secondary analysis we found that the positive association between mild cognitive impairment (MCI) and dementia incidence decreased after 1/3/20 (interaction effect p = 0.031).

CONCLUSION

The incidence of dementia as defined using the CDR global score did not change significantly after the first lockdown began, but we found evidence that lockdown decreased the positive association between MCI and dementia incidence. This may reflect that individuals were progressing to dementia more rapidly and thus missing the MCI stage or that assessing patients over the phone made diagnosing MCI more challenging.

Are Cisgender Women and Transgender and Nonbinary People Drinking More During the COVID-19 Pandemic? It Depends

PURPOSE

This narrative review of research conducted during the first 2 years of the COVID-19 pandemic examines whether alcohol use among cisgender women and transgender and nonbinary people increased during the pandemic. The overarching goal of the review is to inform intervention and prevention efforts to halt the narrowing of gender-related differences in alcohol use.

SEARCH METHODS

Eight databases (PubMed, APA PsycInfo, CINAHL, Embase, Scopus, Gender Studies Database, GenderWatch, and Web of Science) were searched for peer-reviewed literature, published between March 2020 and July 2022, that reported gender differences or findings specific to women, transgender or nonbinary people, and alcohol use during the pandemic. The search focused on studies conducted in the United States and excluded qualitative research.

SEARCH RESULTS

A total 4,132 records were identified, including 400 duplicates. Of the remaining 3,732 unique records for consideration in the review, 51 were ultimately included. Overall, most studies found increases in alcohol use as well as gender differences in alcohol use, with cisgender women experiencing the most serious consequences. The findings for transgender and nonbinary people were equivocal due to the dearth of research and because many studies aggregated across gender.

DISCUSSION AND CONCLUSIONS

Alcohol use by cisgender women seems to have increased during the pandemic; however, sizable limitations need to be considered, particularly the low number of studies on alcohol use during the pandemic that analyzed gender differences. This is of concern as gender differences in alcohol use had been narrowing before the pandemic; and this review suggests the gap has narrowed even further. Cisgender women and transgender and nonbinary people have experienced sizable stressors during the pandemic; thus, understanding the health and health behavior impacts of these stressors is critical to preventing the worsening of problematic alcohol use.

Cortical GABA Levels Are Reduced in Post-Acute COVID-19 Syndrome

After recovering from the acute COVID-19 illness, a substantial proportion of people continue experiencing post-acute sequelae of COVID-19 (PASC), also termed "long COVID". Their quality of life is adversely impacted by persistent cognitive dysfunction and affective distress, but the underlying neural mechanisms are poorly understood. The present study recruited a group of mostly young, previously healthy adults (24.4 ± 5.2 years of age) who experienced PASC for almost 6 months following a mild acute COVID-19 illness. Confirming prior evidence, they reported noticeable memory and attention deficits, brain fog, depression/anxiety, fatigue, and other symptoms potentially suggestive of excitation/inhibition imbalance. Proton magnetic resonance spectroscopy (1H-MRS) was used to examine the neurochemical aspects of cell signaling with an emphasis on GABA levels in the occipital cortex. The PASC participants were compared to a control (CNT) group matched in demographics, intelligence, and an array of other variables. Controlling for tissue composition, biological sex, and alcohol intake, the PASC group had lower GABA+/water than CNT, which correlated with depression and poor sleep quality. The mediation analysis revealed that the impact of PASC on depression was partly mediated by lower GABA+/water, indicative of cortical hyperexcitability as an underlying mechanism. In addition, N-acetylaspartate (NAA) tended to be lower in the PASC group, possibly suggesting compromised neuronal integrity. Persistent neuroinflammation may contribute to the pathogenesis of PASC-related neurocognitive dysfunction.

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.

Mapping COVID vulnerability in relation to drug and alcohol recovery residence availability across the United States

Recovery housing is an important resource for those in recovery from substance use disorders. Unfortunately, we know little about its relationship to key community health risk and protective factors, potentially limiting the role it could play as a broader health resource. Leveraging county-level data on recovery residences from the National Study of Treatment and Addiction Recovery Residences (NSTARR), this study used multilevel modeling to examine Community COVID Vulnerability Index (CCVI) scores as well as availability of COVID testing and vaccination sites in relation to recovery housing. CCVI composite scores were positively associated with recovery housing availability. Analyses using CCVI thematic sub-scores found that population density and number of churches were positively associated with recovery housing availability, while epidemiological factors and healthcare system factors were negatively associated with recovery housing availability. In counties with recovery housing, there also was a positive association between CCVI and both COVID testing and vaccination availability. Recovery residences tend to be located in areas of high COVID vulnerability, reflecting effective targeting in areas with higher population density, more housing risk factors, and other high-risk environments and signaling a key point of contact to address broader health issues among those in recovery from substance use disorders.

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.

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.

Insights of mitochondrial involvement in alcoholic fatty liver disease

Alcoholic liver disease (ALD) is a global concern affecting most of the population and leading to the development of end-stage liver disease. Metabolic alterations due to increased alcohol consumption surge the hepatic accumulation of lipids and develop into a severe form of alcoholic steatohepatitis (ASH), depending on age and the consumption rate. The mitochondria in the hepatocyte actively regulate metabolic homeostasis and are disrupted in ALD pathogenesis. The increased NADH upon ethanol metabolism inhibits the mitochondrial oxidation of fatty acids, alters oxidative phosphorylation, and favors de novo lipogenesis. The higher mitochondrial respiration in early ALD increases free radical generation, whereas mitochondrial respiration is uncoupled in chronic ALD, affecting the cellular energy status. The defective glutathione importer due to excessive cholesterol loading and low adenosine triphosphate accounts for additional oxidative stress leading to hepatocyte apoptosis. The defective mitochondrial transcription machinery and sirtuins function in ALD affect mitochondrial function and biogenesis. The metabolites of ethanol metabolism epigenetically alter the gene expression profile of hepatic cell populations by modulating the promoters and sirtuins, aiding hepatic fibrosis and inflammation. The defect in mitophagy increases the accumulation of megamitochondria in hepatocytes and attracts immune cells by releasing mitochondrial damage-associated molecular patterns to initiate hepatic inflammation and ASH progression. Thus, maintaining mitochondrial lipid homeostasis and antioxidant capacity pharmacologically could provide a better outcome for ALD management.

A pharmacist-led community-based survey study: Determining the impact of the Covid-19 pandemic on actionable factors associated with worse cancer outcomes and cancer health disparities

Purpose

The goals of this cross-sectional community-based survey study were to assess the impact of the Covid-19 pandemic on actionable factors which are known to contribute to worse cancer outcomes, and to determine whether race and ethnicity-based differences exist.

Methods

A survey study which captured demographic information and changes in cancer outcomes-related factors since the start of the Covid-19 pandemic, was conducted at a public Covid-19 vaccination clinic over a period of 10 days during March 2021. Surveys were administered in multiple languages. Chi-square tests and ANOVA followed by post-hoc Dunnett testing assessed for race and ethnicity-based differences.

Results

A total of 949 people participated (61.6% participation rate). Ninety-three surveys were removed based on inclusion criteria giving a final participant number of 856. Many participants reported postponing cancer screenings (17.8%) and cancellation of medical appointments (22.8% and 25.8% reported cancelled appointments by providers or themselves, respectively) due to the pandemic. Participants also reported decreased physical activity (44.7%) and increased tobacco and/or marijuana usage (7.0%). Conversely, participants reported consuming more fruits and vegetables (21.4%) and decreasing alcohol consumption (21.4%). Several race-related differences but no ethnicity-related differences were observed.

Conclusion

Our data can be used to help guide pharmacist-led targeted outreach in our community which will help mitigate Covid-19 pandemic-driven changes in behaviors associated with worse cancer outcomes and exacerbation of cancer health disparities. To our knowledge, this is the first cancer outcomes-related study to be conducted at a public Covid-19 vaccination site and is the first pharmacist-led study in this area.

Pandemic-Related Changes in the Prevalence of Early Adolescent Alcohol and Drug Use, 2020-2021: Data From a Multisite Cohort Study

PURPOSE

Evaluate changes in early adolescent substance use from May 2020 to May 2021 during the coronavirus disease 2019 pandemic using data from a prospective nationwide cohort: the Adolescent Brain Cognitive Development Study.

METHODS

In 2018-2019, 9,270 youth aged 11.5-13.0 completed a prepandemic assessment of past-month alcohol and drug use, then up to seven during-pandemic assessments between May 2020 and May 2021. We compared the prevalence of substance use among same-age youth across these eight timepoints.

RESULTS

Pandemic-related decreases in the past-month prevalence of alcohol use were detectable in May 2020, grew larger over time, and remained substantial in May 2021 (0.3% vs. 3.2% prepandemic, p <.001). Pandemic-related increases in inhalant use (p = .04) and prescription drug misuse (p < .001) were detectable in May 2020, shrunk over time, and were smaller but still detectable in May 2021(0.1%-0.2% vs. 0% pre-pandemic). Pandemic-related increases in nicotine use were detectable between May 2020 and March 2021 and no longer significantly different from prepandemic levels in May 2021 (0.5% vs. 0.2% prepandemic, p = .09). There was significant heterogeneity in pandemic-related change in substance use at some timepoints, with increased rates among youth identified as Black or Hispanic or in lower-income families versus stable or decreased rates among youth identified as White or in higher-income families.

DISCUSSION

Among youth ages 11.5-13.0 years old, rates of alcohol use remained dramatically reduced in May 2021 relative to prepandemic and rates of prescription drug misuse and inhalant use remained modestly increased. Differences remained despite the partial restoration of prepandemic life, raising questions about whether youth who spent early adolescence under pandemic conditions may exhibit persistently different patterns of substance use.

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.

Inequitable access to general and behavioral healthcare in the US during the COVID-19 pandemic: A role for telehealth?

Wide-ranging effects of the COVID-19 pandemic have led to increased psychological distress and alcohol consumption, and disproportionate hardship for disadvantaged groups. Early in the pandemic, telehealth services were expanded to maintain healthcare access amidst lockdowns, medical office closures, and fear of infection. This study examines general and behavioral healthcare access and disparities during the first year of the pandemic. Data are from the 2019-2020 US National Alcohol Survey (collected February 2019 to April 2020) and its COVID follow-up survey conducted January 30 to March 28, 2021 (N = 1819). General and behavioral healthcare-related outcomes were assessed at follow-up, and included perceived need for and receipt of care, delayed care, and use of telehealth since April 1, 2020. Results indicate that the majority of respondents with perceived need for healthcare received some behavioral healthcare (reported by 63%) and particularly general healthcare (88%), but nearly half (48%) delayed needed care. Delays were mostly due to COVID-related reasons, but cost barriers also were common and significantly impeded care-seeking by uninsured persons, young adults, rural residents, and persons whose employment was reduced by the pandemic. Disparities in the receipt of healthcare were pronounced for Hispanic/Latinx (vs. White) and lower-income (vs. higher-income) groups (AORs <0.37, p's < 0.05). Notably, telehealth was commonly used by Hispanic/Latinx and lower-income groups for general and particularly behavioral healthcare. Results suggest that telehealth has provided an important bridge to healthcare for certain medically underserved groups during the pandemic, and may be vital to future efforts to increase equity in healthcare access.
