Effects of medical school on mental health and sleep habits

Abstract

ABSTRACTBACKGROUND and OBJECTIVESThis study aims to define changes in anxiety and depression among medical students while evaluating the association of sleep habits and other risk factors, including exercise habits and a diagnosis of chronic disease. The effect of the COVID-19 pandemic was also evaluated.DESIGNA cohort of first- and second-year medical students was evaluated longitudinally using survey methods to quantify changes from pre-medical school and summer break to each semester in medical school throughout years one and two.METHODSData was analyzed using Generalized Linear Mixed Models (GLMMs) on the numeric responses of General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Pittsburg Sleep Quality Index. Additional assessments evaluated exercise habits, chronic disease, and impact of COVID-19 Pandemic.RESULTSDepression, anxiety, and sleep habits displayed a cyclical change that was associated with the academic cycle. The COVID-19 pandemic was never significant. Medical students who had a chronic disease diagnosis had increased severity. Exercise did not play a role.CONCLUSIONThe main driver for depression, anxiety, and poor sleep quality was the academic cycle, while the COVID-19 pandemic did not have an impact on mental health.
