Predictors of quality of life among Brazilian medical students during second coronavirus wave

Objective: To assess the impact of COVID-19 second wave on quality of life (QoL) of Brazilian medical students. Methods: The data from 210 medical students were collected through a web-based survey between February and March 2021. We assessed information about sociodemographic characteristics, health conditions, electronics tools-related to physical activity (PA-eTool), and health-associated QoL. Multiple linear regression was performed to identify the potential QoL predictors. Results: The psychological domain was the most affected, showing lower score during COVID-19 second wave. Being male was a positive predictor in the physical health domain. Spending too much time indoors and sexual minority-group membership were associated with lower perception on psychological well-being. Personal benefit from having PA-eTool accessed and higher income were positively associated with psychological and environmental domains, respectively, and in the overall QoL. Conclusions: Psychological well-being impairment is a long-term negative impact among Brazilian medical students during COVID-19. By evidencing that students' QoL has been worsened in this global crisis, supportive interventions provided by community and universities are required to aid those vulnerable students facing mental health or QoL impairment.
