Mental Health of Medical Students Before and During COVID-19 Pandemic: a 3-Year Prospective Study.

Background: Very few studies prospectively analyzed medical students' mental health before and during the COVID-19 pandemic. This study aimed to prospectively evaluate mental health in medical students in 2018, 2019, and 2020 during the COVID-19 pandemic lockdown.

Methods: All students from first to fourth year were invited to participate in 2018.

Mental health in medical students during COVID-19 quarantine: a comprehensive analysis across year-classes.

Objectives: The COVID-19 pandemic brought abrupt changes when quarantine measures were implemented. Most medical students had distance learning as their main content delivery mode, but in clerkship (fifth and sixth years), in-person activities were maintained under new protocols. These different modes may have affected student mental health.
