Aims: The aims of this study were to identify alcohol‐related population surveys administered in the Americas, determine which alcohol‐related measures are examined and identify coverage gaps regarding alcohol‐related measures. Methods: As part of the Global Information System on Alcohol and Health study, a systematic search was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses criteria to identify regionally or nationally representative survey reports of the general population from 1 January 2010 to 6 August 2019. Alcohol‐related measures extracted from surveys were categorized into 10 domains: alcohol consumption status; alcohol consumption; unrecorded alcohol consumption; drinking patterns; symptoms of dependence and/or harmful use; drinking during pregnancy; treatment coverage; second‐hand harms; economic; and other. Results: The systematic search identified 7417 survey reports, 94 of which were new and included in this study, with an additional 11 studies included from a previous systematic study of alcohol surveys. In total, 94 unique surveys and 161 unique survey waves were located, representing 105 unique survey questionnaires covering 30 countries. No population surveys were found for five member states; namely, Antigua and Barbuda, Dominica, Haiti, Saint Vincent and the Grenadines and Saint Kitts and Nevis. All countries with population‐based alcohol surveys had had a population survey probing alcohol use in the past year/month. Questions regarding heavy episodic drinking, alcohol use disorders, treatment‐seeking for alcohol use, drinking during pregnancy, harms to others and the amounts spent on alcohol were asked in 26, 25, 10, 6, 22 and 11 countries, respectively. Conclusions: The heterogeneity in alcohol‐related population surveys in the Americas from 2010 to 2019 limits their comparability throughout countries and over time. Future surveys should implement a standardized set of core questions to provide consistency in the monitoring of alcohol consumption and alcohol‐related harms. [ABSTRACT FROM AUTHOR]

Alcohol consumption is an established cause of female breast cancer. This systematic review examines in detail the association between alcohol and female breast cancer overall and among the described subgroups, using all of the evidence to date. A systematic review of PubMed and Embase was performed according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. The search included articles published up to November 15, 2023. Meta‐analyses and regressions were performed for alcohol consumption of less than 1 standard drink (10 g of ethanol) per day and for a range of alcohol consumption categories in relation to breast cancer. Analyses by menopausal status, hormone receptor status, human epidermal growth factor receptor 2 status, and molecular subtype were performed. The search yielded 5645 publications, of which 23 publications of individual and pooled studies examined the association between overall alcohol consumption and breast cancer incidence. The meta‐regression showed a positive association; relative risks (RR) of breast cancer were 1.05 (95% CI: 1.04, 1.06), 1.10 (95% CI: 1.08, 1.12), 1.18 (95% CI: 1.15, 1.21), and 1.22 (95% CI: 1.19, 1.25) for 0.5, 1, 2, and 3 standard drinks per day compared with nondrinking, respectively. A meta‐analysis of nine studies indicated that for consumption of less than one standard drink per day, the RR estimate of breast cancer was 1.04 (95% CI: 1.01, 1.07) compared with nondrinking. Consumption of an additional 1 standard drink per day was associated with a higher risk of premenopausal (RR: 1.03 (95% CI: 1.01, 1.06)) and postmenopausal (RR: 1.10 (95% CI: 1.08, 1.12)) breast cancer. Alcohol consumption increases female breast cancer risk, even for women who consume one drink per day. Furthermore, alcohol consumption is associated with both pre‐ and postmenopausal breast cancer risk. These findings support evidence‐based cancer prevention guidelines to reduce alcohol‐related risks. [ABSTRACT FROM AUTHOR]

Aim To examine whether changes in alcohol consumption in Canada since the start of the novel coronavirus disease (COVID-19) pandemic are associated with feelings of anxiety, depression, loneliness and/or with changes in employment due to COVID-19. Methods Data collection occurred between 29 May 2020 and 23 March 2021 via a web panel, AskingCanadians, which sampled 5892 adults (≥18 years of age). Data were collected on changes in alcohol consumption compared to before the pandemic (ordinal variable ranging from 1='much less alcohol' to 5='much more alcohol'), anxiety (General Anxiety Disorder-7), self-perceived depression (Center for Epidemiologic Studies Depression Scale), self-perceived loneliness, changes in employment status due to COVID-19 and socio-demographic variables (age, gender, living situation, household income and urban vs rural residence). Multivariate associations were assessed using ordinal logistic regression. Effect modification by gender was tested using likelihood-ratio tests. Results Changes in alcohol consumption were positively associated with anxiety, feeling depressed and loneliness. In particular, people with mild to moderate (ordered Odds Ratio (OR):1.23, 95% Confidence Interval (CI):1.07, 1.62) or severe anxiety (ordered OR:1.49, 95% CI:1.15, 1.93) had a greater odds of increased drinking than did people with no to low levels of anxiety. Gender, age, household income, living situation and survey wave were also associated with changes in drinking. No effect modifications by gender were observed. Conclusion Given the health harms caused by alcohol use, public health practitioners and primary care physicians should focus health messaging to identify and support individuals at risk of increased alcohol consumption, especially people experiencing depression, loneliness or anxiety.
