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

In contrast to our initial hypothesis, stable results on mental health measures were found even during the 2020 COVID-19 lockdown. Maintenance of daily routines through distance learning and the continuation of adapted clerkship activities with strict safety measures could have contributed to these results. However, this study points to high overall levels of common mental disorders, especially among women. Further studies should be conducted to understand all the factors responsible for such stability, such as social and economic support, resilience, or even previous high levels of common mental disorders.
