Seminar Abstract In this presentation, we explore the impact of the COVID-19 pandemic on changes in alcohol consumption habits among healthcare workers in the United States during the first wave of the pandemic. Using a variety of supervised and unsupervised machine learning methods and models, including decision trees, logistic regression, support vector machines, multilayer perceptrons, XGBoost, CatBoost, LightGBM, AdaBoost, Chi-Squared Test, mutual information, KModes clustering, and the synthetic minority oversampling technique, we analyzed mental health survey data from the University of Michigan Inter-University Consortium for Political and Social Research. Our objective was to investigate the connections between COVID-19-related adverse effects and shifts in alcohol consumption habits among healthcare workers. Our analysis of the supervised and unsupervised methods revealed that healthcare workers who had children at home during the first wave of the pandemic in the US consumed more alcohol. We also found that changes in work schedules due to the COVID-19 pandemic were linked to alterations in alcohol use habits. Additional factors, such as changes in food consumption, age, gender, geographical characteristics, changes in sleep habits, news consumption volume, and screen time, also significantly predicted increased alcohol use among healthcare workers in the United States. Instructors Biosketch Dr. Mostafa Rezapour is currently a Research Fellow at the Center for Biomedical Informatics at Wake Forest University School of Medicine.
