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

Alcohol-Attributable Cancer: Update From the Global Burden of Disease 2021 Study

BACKGROUND AND AIMS

Alcohol is a major risk factor for cancer development. Our study aimed to provide the updated global, regional and national burden of alcohol-attributable cancer.

APPROACH AND RESULTS

We analysed the Global Burden of Disease Study 2021 to determine the death and age-standardised death rate (ASDR) from alcohol-attributable cancer and the change of these measures between 2000 and 2021 (reflected as annual percent change [APC]), classified by region, nation and country's developmental status, which is based on the sociodemographic index (SDI).

RESULTS

In 2021, there were 343,370 deaths globally from alcohol-attributable cancer, which was an increase from 2000 by 51%. Alcohol-attributable cancer accounted for 3.5% of all cancer deaths. Among alcohol-attributable cancer, liver cancer (27%) accounted for the highest mortality from alcohol, followed by oesophageal (24%) and colorectal cancer (16%). From 2000 to 2021, ASDR from alcohol-attributable cancer decreased (APC: -0.66%). Regionally, from 2000 to 2021, the fastest-growing ASDR was observed in South Asia. Classified by SDI, low (APC: 0.33%) and low-to-middle SDI countries (APC: 1.58%) exhibited an uptrend in ASDR from alcohol-attributable cancer. While the ASDR from all other cancers decreased, ASDR from early-onset (15-49 years) lip and oral cavity cancer increased (APC: 0.40%).

CONCLUSIONS

From 2000 to 2021, although the ASDR from alcohol-attributable cancer declined, the total number of deaths continued to rise. This trend was accompanied by variations across sociodemographic groups and cancer types, particularly gastrointestinal cancers. Urgent efforts are needed both globally and at regional levels to address the burden of alcohol-attributable cancers.

Rural-Urban Disparities in Mortality Related to Alcohol-Associated Liver Disease by Race/Ethnicity in the United States From 1999 to 2022

INTRODUCTION

Mortality related to alcohol-associated liver disease (ALD) has been increasing over the past two decades, especially in racial and ethnic minorities and those living in rural areas. The interaction between rurality, race and ethnicity in mortality disparities is unclear.

METHODS

This cross-sectional study extracted data from the Underlying Cause of Death database of CDC Wide-Ranging Online Database for Epidemiological Research (1999-2022). We estimated the age-adjusted mortality rates (AAMRs) for ALD among adults 25 years and older. We calculated the average annual percentage change (AAPC) using the Joinpoint regression program.

RESULTS

There were 436,814 deaths related to ALD among US adults with rising mortality from 1999 (AAMR, 6.7) to 2022 (AAMR, 12.5) (AAPC, 2.7%). American Indian and Alaska Native (AI/AN) individuals had the highest mortality in 2022 (AAMR, 76.8), followed by Hispanic individuals (AAMR, 14.1). Mortality increases in non-Hispanic White (NHW) individuals (AAPC, 4.0%) surpassed that of non-Hispanic Black (NHB) individuals (AAPC, 0.4%). The increase in AAMR was more pronounced in rural areas (AAPC, 4.1%) than large metropolitan areas (AAPC, 2.0%). For NHW, AI/AN, and Hispanic individuals, AAMRs in rural areas had greater increases than in large metropolitan areas. AAMRs remained largely stable in large metropolitan (AAPC, - 0.6%) and rural areas for NHB individuals (AAPC, 0.1%).

DISCUSSION

There were significant and widening rural-urban disparities in ALD-related mortality among NHW, AI/AN, and Hispanic individuals. Mortality in NHB individuals remained largely stable. Targeted resources and efforts are essential to address the growing mortality burden in select populations.

Global epidemiology of alcohol-related liver disease, liver cancer, and alcohol use disorder, 2000-2021

BACKGROUND/AIMS

Alcohol represents a leading burden of disease worldwide, including alcohol use disorder (AUD) and alcohol-related liver disease (ALD). We aim to assess the global burden of AUD, ALD, and alcohol-attributable primary liver cancer between 2000-2021.

METHODS

We registered the global and regional trends of AUD, ALD, and alcohol-related liver cancer using data from the Global Burden of Disease 2021 Study, the largest and most up-to-date global epidemiology database. We estimated the annual percent change (APC) and its 95% confidence interval (CI) to assess changes in age-standardized rates over time.

RESULTS

In 2021, there were 111.12 million cases of AUD, 3.02 million cases of ALD, and 132,030 cases of alcohol-attributable primary liver cancer. Between 2000 and 2021, there was a 14.66% increase in AUD, a 38.68% increase in ALD, and a 94.12% increase in alcohol-attributable primary liver cancer prevalence. While the age-standardized prevalence rate for liver cancer from alcohol increased (APC 0.59%; 95% confidence interval [CI] 0.52 to 0.67%) over these years, it decreased for ALD (APC -0.71%; 95% CI -0.75 to -0.67%) and AUD (APC -0.90%; 95% CI -0.94 to -0.86%). There was significant variation by region, socioeconomic development level, and sex. During the last years (2019-2021), the prevalence, incidence, and death of ALD increased to a greater extent in females.

CONCLUSION

Given the high burden of AUD, ALD, and alcohol-attributable primary liver cancer, urgent measures are needed to prevent them at both global and national levels.

Disparities in Alcohol-Associated Liver Disease Hospital Encounters Amongst a Texas-Based Cohort of Patients

INTRODUCTION

Alcohol-associated liver disease (ALD) disproportionately impacts men, racial and ethnic minorities, and individuals of low socioeconomic status; however, it's unclear how recent increases in ALD burden have impacted these disparities. We aimed to describe trends in racial, ethnic and socioeconomic disparities in alcohol-associated hospital encounters.

METHODS

We conducted a retrospective cohort study of adult hospital encounters with alcohol-associated diagnoses from three health systems between January 2016 and December 2021. The cohort was divided into three eras: a 'Historical Era,' (Oct 2016-June 2018, used only for trends); 'Era 1' (July 2018-March 2020); and 'Era 2' (April 2020-December 2021). Kaplan Meier and Cox regression analyses were performed to identify factors associated with overall survival.

RESULTS

We identified 19,295 individuals with alcohol-associated encounters (44.7% White, 29.8% Hispanic, and 21.8% non-Hispanic Black (NHB) individuals), with a greater increase observed between eras 1 and 2 than the historical era and Era 1 (8.7% vs. 5.0%, p < 0.01). By age and sex, the greatest increases in encounters were observed in the youngest and oldest females but only the oldest males. By race and ethnicity, Hispanic individuals had greater increases in encounters compared to Black and White individuals (14.8% vs. 7.5% and 6.3%, p < 0.01). Older age (aSHR: 1.03, 95% CI: 1.03-1.0), higher MELD (aSHR: 1.08, 95% CI: 1.0-1.09), hepatic encephalopathy (aSHR: 1.42, 95% CI: 1.06-1.90), and hepatocellular carcinoma (HCC) (aSHR: 3.20, 95% CI: 2.29-4.49) were associated with increased mortality.

CONCLUSION

The highest increases of alcohol-associated encounters were observed amongst young Hispanic and NHB women, highlighting variation in trends by age, sex, race and ethnicity. These disparities merit further investigation to elucidate underlying mechanisms and develop tailored interventions to improve ALD burden and outcomes.

Mental health, substance use, and a composite of sleep health in adults, 2018 Ohio behavioral risk factor surveillance system

OBJECTIVES

Various factors impact sleep health including mental health and substance use. Mental health issues and substance use continue to rise in the United States. Yet, the association between mental health, substance use and sleep health in adults remains unclear.

METHODS

We used multivariable linear regression models to examine the associations between mental health (poor mental health days in the past 30 days) and substance use (marijuana, tobacco, alcohol) with sleep health (individual dimensions of sleep: alertness, sleep efficiency, duration, and sleep health composite score) in 4333 participants from the 2018 Ohio Behavioral Risk Factor Surveillance System Survey.

RESULTS

Better mental health was associated with higher alertness, higher sleep efficiency, longer sleep duration and a higher sleep health composite score even after controlling for covariates (individual: sex at birth, age, body mass index, race, education, sleep disordered breathing, and area-level: socioeconomic deprivation) (all p < .001). Higher marijuana and tobacco use were associated with lower individual sleep health dimensions (marijuana with sleep efficiency and duration and tobacco use with lower efficiency) and a lower sleep health composite score even after controlling for covariates for tobacco use (p < .001). Contrary to the hypothesis, higher alcohol use was associated with higher alertness and a higher sleep health composite score (p < .001), however after adjusting for covariates these associations were no longer significant.

CONCLUSIONS

The implications of these trends on sleep health are important to address as mental health and substance use are modifiable targets to consider when addressing sleep health.

Alcohol and Atrial Fibrillation: An Update and New Perspectives

In the Western world, sales of alcoholic beverages are skyrocketing. Alcohol (ethanol) is consumed for its transient euphoric effects but is a risk factor for the development of heart disease. Here, we review the possible association between alcohol consumption and atrial fibrillation. Using a familiar analogy, we propose that atrial fibrillation is the mere tip of an iceberg (alcohol-associated heart disease). Our concern is that the many research studies on the effects of ethanol on the heart have produced inconsistent results. These include studies of individuals drinking only moderate amounts of alcoholic beverages (aka the "French paradox") on the one hand, and paroxysmal atrial fibrillation after binge drinking ("holiday heart syndrome") on the other hand. The evidence available in the literature suggests that hypertension, structured heart disease of any form, neurohumoral stress, and cardiometabolic disorders all favor the development of atrial fibrillation triggered by alcohol. We also suggest that alcohol should be classified as a modifiable risk factor for atrial fibrillation, and also for heart disease in general.

A Novel Mouse Home Cage Lickometer System Reveals Sex- and Housing-Based Influences on Alcohol Drinking

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

The burden of alcohol-related cardiovascular complications in young and middle-aged adults: rising burden of atrial fibrillation and hypertensive heart disease

BACKGROUND AND AIMS

The burden of alcohol-related complications is high and rising. However, there are notable deficiencies in comprehensive epidemiological study focusing on cardiovascular complications from alcohol, especially among young and middle-aged adults. We thus aimed to determine the burden of these conditions in young and middle-aged adults globally.

METHODS AND RESULTS

We used data from the Global Burden of Disease Study 2019 and analysed the mortality and disability-adjusted life years of alcohol-associated cardiovascular complications in young and middle-aged adults. The findings were classified by sex, region, country, and Sociodemographic Index (SDI). The highest age-standardized death rates (ASDR) were observed in stroke 0.84 (95% UI 0.60-1.09), followed by alcoholic cardiomyopathy 0.57 (95% UI 0.47-0.66) per 100,000 population. The overall burden of alcohol-associated cardiovascular complications decreased globally but increased in atrial fibrillation and hypertensive heart disease. Regionally, most regions underwent a decrease in ASDR, but an increase was observed in Southeast Asia (+2.82%), Western Pacific (+1.48%), low-middle (+1.81%), and middle SDI (+0.75%) countries. Nevertheless, the ASDR and ASDALYs were highest in Europe.

CONCLUSIONS

The impact of alcohol-associated atrial fibrillation and hypertensive heart disease has increased over the last decades. Regarding region, the burden in Europe and the rising burden in Asia, require immediate public health policy to lessen these cardiovascular complications from alcohol in young and middle-aged adults.

From Shadows to Spotlight: Exploring the Escalating Burden of Alcohol-Associated Liver Disease and Alcohol Use Disorder in Young Women

INTRODUCTION

The burden of alcohol-related complications is considerable, particularly alcohol-associated liver disease and alcohol use disorder (AUD). However, there are deficiencies in comprehensive epidemiological research focusing on these issues, especially among young women who display higher susceptibility to such complications compared with their male counterparts. We thus aimed to determine the global burden of these conditions in this vulnerable group.

METHODS

Leveraging data from the Global Burden of Disease Study 2019, we analyzed the prevalence, mortality, and disability-adjusted life years of alcohol-associated cirrhosis (AC), liver cancer from alcohol, and AUD in young women. The findings were categorized by region, nation, and sociodemographic index.

RESULTS

The highest age-standardized prevalence rates were observed in AUD (895.96 [95% uncertainty interval (UI) 722.6-1,103.58]), followed by AC (65.33 [95% UI 48.37-86.49]) and liver cancer from alcohol (0.13 [95% UI 0.09-0.19]) per 100,000 people. The highest age-standardized mortality rates were observed in AC (0.75 [95% UI 0.55-0.97]), followed by AUD (0.48 [95% UI 0.43-0.53]) and liver cancer from alcohol (0.06 [95% UI 0.04-0.09]). The highest burdens of AC and AUD were observed in Central Europe, whereas the high-income Asia Pacific had the highest burden of liver cancer from alcohol.

DISCUSSION

Throughout the past decade, the trend of AUD varied among regions while the impact of alcohol-associated liver disease has increased, requiring urgent public health strategy to mitigate these complications, particularly in female patients in Europe and the Asia-Pacific region.
