Relationship between high-risk alcohol consumption and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroconversion: a prospective sero-epidemiological cohort study among American college students

Impact of the COVID-19 pandemic on violence exposure and alcohol use among adults who drink alcohol

The COVID-19 pandemic has exacerbated prevalence of alcohol use and violence, including gender-based violence (GBV); however, little is understood about the pandemic's impact on the relationship between the two. Data were collected from January 2021-April 2023 with adults who drink alcohol (N = 565) in the San Francisco Bay Area. Questions assessed prevalence of heavy alcohol use (≥4 drinks on one occasion ≥4 times a month) in the past 3 months and violence/GBV exposure before and during the pandemic. Logistic regression examined associations between violence and alcohol use. Overall, participants reported heavy alcohol use (73.7%), strong desire for alcohol (53.3%), ever experiencing violence (71.6%), and GBV (20.5%). During the pandemic, participants reported experiencing violence (26.1%), more violence than usual (13.8%), GBV (8.9%), and drinking more alcohol (43.7%). People who experienced violence during the pandemic had significantly greater odds of reporting heavy alcohol use (OR = 1.76, p = 0.05) and drinking more during the pandemic than usual (OR = 2.04, p<0.01). Those who reported experiencing more violence during the pandemic than usual had significantly greater odds of reporting heavy alcohol use (OR = 2.32, p = 0.04) and drinking more during the pandemic (OR = 2.23, p<0.01). People who experienced GBV during the pandemic reported a significantly stronger desire for alcohol (OR = 2.44; p = 0.02) than those not exposed. Alcohol-related harms increased over the COVID-19 pandemic, including increased violence/GBV, alcohol use, and an elevated desire to use alcohol among those who experienced violence during the pandemic. Future pandemic preparedness efforts must prioritize violence prevention strategies and adapt alcohol harm reduction, recovery, and treatment programs to pandemic conditions.

Changes in alcohol consumption among medical students during the COVID-19 pandemic - results from POLLEK study

OBJECTIVES

Social distancing and remote learning as one of the ways to fight against COVID-19 pandemic have affected universities and changed the lifestyle of many students. Psychoactive substances use was one of the way to deal with the anxiety caused by these new settings. Studies published so far have not provided a clear answer on whether COVID-19 leads to changes in the structure of alcohol consumption among medical students. The presented study attempted to answer this question based on the data available from the POLLEK study.

MATERIAL AND METHODS

The study group included 3 separate groups of medical students (recruited in the following academic years: 2019/2020, 2020/2021, and 2021/2022) with a total number of 899 students. To assess the characteristics of alcohol consumption the authors used a Polish version of the Alcohol Use Disorder Identification Test (AUDIT).

RESULTS

Students surveyed during the lockdown lived in the family home much more often, reported good health, and declared consumption of a smaller number of alcoholic beverages. Their AUDIT scores were statistically significantly (p = 0.04) lower compared to the group surveyed before the pandemic (5 vs. 6, respectively). There were no significant differences in the AUDIT results between other study periods.

CONCLUSIONS

Lockdown due to COVID-19 pandemic might be associated with a decrease in alcohol intake among medical students. This may be due to a different place of residence of students, a family home rather than a dormitory. However, the debate on this topic seems to be still open.

Substances of abuse and their effect on SAR-CoV-2 pathogenesis

Following the emergence of SARS-CoV-2, various reports suggest that there has been a significant increase in substance abuse due to social distancing and related issues. Several reports have suggested the impact of chronic substance use on individuals' physiological and psychological health. Therefore, there is a need to know the impact of SARS-CoV-2 on persons with substance use disorders. Individuals with substance use disorders are the most vulnerable groups and are at a high risk of SARS-CoV-2 infection due to their already existing health issues associated with substance use. This review discusses some of the molecular and systemic/organic effects chronic substance use such as alcohol, nicotine, marijuana (cannabis), opioids, methamphetamine, and cocaine have on SARS-CoV-2 infectivity and its potential cause for worsened disease outcomes in persons with substance use disorder. This will provide healthcare providers, public health policies, and researchers with the needed knowledge to address some of the many challenges faced during the Covid-19 pandemic to facilitate treatment strategies for persons with substance use disorders.

COVID-19 and alcohol consumption: recommendations in the Omicron era

In the early stages of the pandemic, the first reports began that alcohol consumption could increase the risk of becoming infected and worsening the prognosis disease. This is for two reasons: behavioral and socio-economic factors that characterize a part of this population can be the cause of viral spread and a direct or indirect negative action of ethanol on the immune system. The data used for the preparation of these recommendations are based on a detailed analysis of the scientific literature published before March 31, 2022 (Web of Science, Scopus, Google Scholar). Furthermore, in the process of developing this work, we consulted the guidelines/position papers of the Italian Society on Alcohol and of the World Health Organization. It has been confirmed that AC is in COVID-19 era a risky behavior and that AUD and substance use disorder (SUD) patients are certainly at greater risk of contracting infection and also of having a worse course. In light of what has been said, some recommendations can be made: correctly inform the general population that AC negatively interacts with COVID-19 infection; reducing the COVID-19 risk by advocating healthy lifestyle habits (smoke, diet, physical exercise, etc.) and preferential policies in population with comorbidities; implement actions that reduce the average consumption of alcohol by avoiding hazardous/harmful consumption. Abstention is better; identify alcohol consumption through a more in-depth alcohol history, using the AUDIT; AUDs patients are frail patients deserving a complete vaccination course; suggest a period of alcoholic abstention of at least thirty days before vaccination to be maintained for the following fifteen days; promoting health education campaigns for young people in order to promote vaccination culture and correct lifestyles.

Changes in the alcohol-specific disease burden during the COVID-19 pandemic in Germany: interrupted time series analyses

BACKGROUND

The coronavirus disease 2019 pandemic has been linked to changes in alcohol consumption, access to healthcare services and alcohol-attributable harm. In this contribution, we quantify changes in alcohol-specific mortality and hospitalizations at the onset of the COVID-19 pandemic in March 2020 in Germany.

METHODS

We obtained monthly counts of deaths and hospital discharges between January 2013 and December 2020 (n = 96 months). Alcohol-specific (International Classification of Diseases, tenth revision codes: F10.X; G31.2, G62.1, G72.1, I42.6, K29.2, K70.X, K85.2, K86.0, Q86.0, T51.X) diagnoses were further split into codes reflective of acute vs. chronic harm from alcohol consumption. To quantify the change in alcohol-specific deaths and hospital discharges, we performed sex-stratified interrupted time series analyses using generalized additive mixed models for the population aged 45-74. Immediate (step) and cumulative (slope) changes were considered.

RESULTS

Following March 2020, we observed immediate increases in alcohol-specific mortality among women but not among men. Between the years of 2019 and 2020, we estimate that alcohol-specific mortality among women has increased by 10.8%. Hospital discharges were analyzed separately for acute and chronic conditions. The total number of hospital discharges fell by 21.4% and 25.1% for acute alcohol-specific conditions for women and men, respectively. The total number of hospital discharges for chronic alcohol-specific conditions fell by 7.4% and 8.1% for women and men, respectively.

CONCLUSIONS

Increased consumption among people with heavy drinking patterns and reduced utilization of addiction-specific healthcare services during the pandemic might explain excess mortality. During times of public health crises, access to addiction-specific services needs to be ensured.

Unintended Consequences of COVID-19 Non-Pharmaceutical Interventions (NPIs) for Population Health and Health Inequalities

Since the start of the COVID-19 pandemic in early 2020, governments around the world have adopted an array of measures intended to control the transmission of the SARS-CoV-2 virus, using both pharmaceutical and non-pharmaceutical interventions (NPIs). NPIs are public health interventions that do not rely on vaccines or medicines and include policies such as lockdowns, stay-at-home orders, school closures, and travel restrictions. Although the intention was to slow viral transmission, emerging research indicates that these NPIs have also had unintended consequences for other aspects of public health. Hence, we conducted a narrative review of studies investigating these unintended consequences of NPIs, with a particular emphasis on mental health and on lifestyle risk factors for non-communicable diseases (NCD): physical activity (PA), overweight and obesity, alcohol consumption, and tobacco smoking. We reviewed the scientific literature using combinations of search terms such as 'COVID-19', 'pandemic', 'lockdowns', 'mental health', 'physical activity', and 'obesity'. NPIs were found to have considerable adverse consequences for mental health, physical activity, and overweight and obesity. The impacts on alcohol and tobacco consumption varied greatly within and between studies. The variability in consequences for different groups implies increased health inequalities by age, sex/gender, socioeconomic status, pre-existing lifestyle, and place of residence. In conclusion, a proper assessment of the use of NPIs in attempts to control the spread of the pandemic should be weighed against the potential adverse impacts on other aspects of public health. Our findings should also be of relevance for future pandemic preparedness and pandemic response teams.

Pathogen exposure misclassification can bias association signals in GWAS of infectious diseases when using population-based common control subjects

Genome-wide association studies (GWASs) have been performed to identify host genetic factors for a range of phenotypes, including for infectious diseases. The use of population-based common control subjects from biobanks and extensive consortia is a valuable resource to increase sample sizes in the identification of associated loci with minimal additional expense. Non-differential misclassification of the outcome has been reported when the control subjects are not well characterized, which often attenuates the true effect size. However, for infectious diseases the comparison of affected subjects to population-based common control subjects regardless of pathogen exposure can also result in selection bias. Through simulated comparisons of pathogen-exposed cases and population-based common control subjects, we demonstrate that not accounting for pathogen exposure can result in biased effect estimates and spurious genome-wide significant signals. Further, the observed association can be distorted depending upon strength of the association between a locus and pathogen exposure and the prevalence of pathogen exposure. We also used a real data example from the hepatitis C virus (HCV) genetic consortium comparing HCV spontaneous clearance to persistent infection with both well-characterized control subjects and population-based common control subjects from the UK Biobank. We find biased effect estimates for known HCV clearance-associated loci and potentially spurious HCV clearance associations. These findings suggest that the choice of control subjects is especially important for infectious diseases or outcomes that are conditional upon environmental exposures.

Factors Associated with Self-Reported Changes in Alcohol Use among Young Adults during the COVID-19 Pandemic: A Comparative Analysis between Canada and France

While the COVID-19 pandemic impacted young adults' alcohol use patterns, little is known about how changes in alcohol use may differ across different settings. Our objective was to identify and compare factors associated with changes in alcohol use among young adults in Canada and France during the first year of the COVID-19 pandemic. We conducted an online cross-sectional survey in October-December 2020 with young adults aged 18-29 (n = 5185) in Canada and France. In each country, weighted multinomial logistic regressions were performed to identify factors associated with self-reported decrease and increase in alcohol use separately (reference: no change). Respectively, 33.4% and 21.4% reported an increase in alcohol use in Canada and France, while 22.9% and 33.5% reported a decrease. Being 25-29 was a predictor of decrease in Canada, while living away from family was associated with an increase in France. In both countries, participants were more likely to report an increase if they reported depressive symptoms, smoking tobacco, or cannabis use. Conversely, those who had been tested for COVID-19 and those who were highly compliant with COVID-19 preventive measures were more likely to report a decrease. Efforts are needed to develop alcohol use interventions for young adults, including in ways that prioritize those with mental health challenges.

SARS-CoV-2 reinfections in a US university setting, Fall 2020 to Spring 2021

BACKGROUND

SARS-CoV-2 reinfections are a public health concern because of the potential for transmission and clinical disease, and because of our limited understanding of whether and how well an infection confers protection against subsequent infections. Despite the public health importance, few studies have reported rigorous estimates of reinfection risk.

METHODS

Leveraging Indiana University's comprehensive testing program to identify both asymptomatic and symptomatic SARS-CoV-2 cases, we estimated the incidence of SARS-CoV-2 reinfection among students, faculty, and staff across the 2020-2021 academic year. We contextualized the reinfection data with information on key covariates: age, sex, Greek organization membership, student vs faculty/staff affiliation, and testing type.

RESULTS

Among 12,272 people with primary infections, we found a low level of SARS-CoV-2 reinfections (0.6%; 0.4 per 10,000 person-days). We observed higher risk for SARS-CoV-2 reinfections in Greek-affiliated students.

CONCLUSIONS

We found evidence for low levels of SARS-CoV-2 reinfection in a large multi-campus university population during a time-period prior to widespread COVID-19 vaccination.
