The Impact

IntroductionSince the WHO declared COVID-19 as a pandemic, the spread of the new coronavirus has been the focus of attention of scientists, governments and populations. One of the main concerns is the impact of this pandemic on health outcomes, mainly on mental health. Even though there are a few empirical studies on COVID-19 and mental health, so far, there is no systematic review about the impact of COVID-19 on mental health of young people and adults yet. We aim to critically synthesise the scientific evidence about the impact of the COVID-19 pandemic on the mental health of young people and adults.Methods and analysisA systematic review will be performed through eight databases: MEDLINE (Medical Literature Analysis and Retrieval System Online), ISI-of-Knowledge, CENTRAL (Cochrane Central Register of Controlled Trials), EMBASE (Excerpta Medica Database), SCOPUS, LILACS (Latin American and Caribbean Health Sciences Literature), PsycINFO (Psychology Information) and CNKI (Chinese National Knowledge Infrastructure), from inception until 30 June 2020. No restriction regarding the publication date, setting or languages will be considered. Preliminary search strategies were carried out on 29 March 2020 and will be updated in June 2020. The primary outcomes will be the prevalence and the severity of psychological symptoms in young people and adults (>18 years old) resulting from the impact of COVID-19 pandemic. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Pooled standardised mean differences and 95% CIs will be calculated. The risk of bias of the observational studies will be assessed through the Methodological Index for Non-Randomised Studies (MINORS). Additionally, if sufficient data are available, a meta-analysis will be conducted. Heterogeneity between the studies will be determined by the I2 statistics. Subgroup analyses will also be performed. Publication bias will be checked with funnel plots and Egger’s test. Heterogeneity will be explored by random-effects analysis.Ethics and disseminationEthical assessment was not required. Findings will be disseminated through peer-reviewed publication and will be presented at conferences related to this field.PROSPERO registration numberCRD42020177366.

The Relationship

IntroductionThere is a substantial literature finding that moderate alcohol consumption is protective against certain health conditions. However, more recent research has highlighted the possibility that these findings are methodological artefacts, caused by confounding and other biases. While modern analytical and study design approaches can mitigate confounding and thus enhance causal inference in observational studies, they are not routinely applied in research assessing the relationship between alcohol use and long-term health outcomes. The purpose of this systematic review is to identify observational studies that employ these analytical/design-based approaches in assessing whether relationships between alcohol consumption and health outcomes are non-linear. This review seeks to evaluate, on a per-outcome basis, what these studies find the strength and form of the relationship between alcohol consumption and health to be.Methods and analysisElectronic databases (MEDLINE, PsycINFO, Embase and SCOPUS) were searched in May 2020. Study selection will comply with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles will be screened against eligibility criteria intended to capture studies using observational data to assess the relationship between varying levels of alcohol exposure and any long-term health outcome (actual or surrogate), and that have employed at least one of the prespecified approaches to enhancing causal inference. Risk of bias of included articles will be assessed using study design-specific tools. A narrative synthesis of the results is planned.Ethics and disseminationFormal ethics approval is not required given there will be no primary data collection. The results of the study will be disseminated through published manuscripts, conferences and seminar presentations.PROSPERO registration numberCRD42020185861.

Functional Forms

Abstract Focus of Presentation Research has long found ‘J-shaped’ relationships between alcohol consumption and certain health outcomes, indicating a protective effect of moderate consumption. However, methodological limitations in most studies hinder causal inference. While enhanced methods for data analysis (e.g. G-methods) and alternative observational designs (e.g. Mendelian Randomisation) have been developed, they are not commonly applied to alcohol–health research. This presentation will report on a systematic review of observational studies that employ improved approaches to mitigate confounding in characterising alcohol–long-term health relationships (PROSPERO registration: CRD42020185861). Findings MEDLINE, PsycINFO, Embase and SCOPUS were searched in May 2020, yielding 16 published manuscripts reporting on cancer, diabetes, dementia, mental health, cardiovascular health, mortality, HIV seroconversion, and musculoskeletal health. Study findings were qualitatively synthesised. A variety of functional forms were found, including reverse J/J-shaped relationships for prostate cancer and related mortality, dementia risk, mental health, and certain lipids. However, most outcomes were only evaluated by a single study, and few studies provided information on the role of alcohol consumption pattern. Conclusions/Implications More research employing enhanced causal inference methods is urgently required to accurately characterise alcohol–long-term health relationships. Those studies that have been conducted find a variety of linear and non-linear functional forms, with results tending to be discrepant even within specific health outcomes. Key messages A systematic review found that those studies of alcohol–long-term health relationships employing enhanced causal methods are too few and inconsistent to establish whether non-linear alcohol–health relationships exist.

ObjectivesThe aim of this review was to explore the notion of alcohol-related presenteeism; that is, whether evidence in the research literature supports an association between employee alcohol consumption and impaired work performance.DesignSystematic review of observational studies.Data sourcesMEDLINE, Web of Science, PsycINFO, CINAHL, AMED, Embase and Swemed+ were searched through October 2018. Reference lists in included studies were hand searched for potential relevant studies.Eligibility criteriaWe included observational studies, published 1990 or later as full-text empirical articles in peer-reviewed journals in English or a Scandinavian language, containing one or more statistical tests regarding a relationship between a measure of alcohol consumption and a measure of work performance.Data extraction and synthesisTwo independent reviewers extracted data. Tested associations between alcohol consumption and work performance within the included studies were quality assessed and analysed with frequency tables, cross-tabulations and χ2tests of independence.ResultsTwenty-six studies were included, containing 132 tested associations. The vast majority of associations (77%) indicated that higher levels of alcohol consumption were associated with higher levels of impaired work performance, and these positive associations were considerably more likely than negative associations to be statistically significant (OR=14.00,phi=0.37, p<0.001). Alcohol exposure measured by hangover episodes and composite instruments were over-represented among significant positive associations of moderate and high quality (15 of 17 associations). Overall, 61% of the associations were characterised by low quality.ConclusionsEvidence does provide some support for the notion of alcohol-related presenteeism. However, due to low research quality and lack of longitudinal designs, evidence should be characterised as somewhat inconclusive. More robust and less heterogeneous research is warranted. This review, however, does provide support for targeting alcohol consumption within the frame of workplace interventions aimed at improving employee health and productivity.PROSPERO registration numberCRD42017059620.
