#COVID#BACKTOSCHOOL: Qualitative study based on the voice of Portuguese adolescents.

Due to the COVID-19 pandemic and the exponential increase in cases, educational institutions worldwide were forced to close, making way for digital learning. After a period of confinement and an online teaching methodology, a new school year has begun. However, this new school year included the application of a wide range of measures that transformed the educative setting. The present study aimed to understand the health consequences for adolescents and young adults (AYA) during the back to school period after the COVID-19 lockdown. This mixed-method study included 304 participants between 16 and 24 years old (M = 18.4, SD = 2.12), female (71.1%), Portuguese (90.8%) and students (85.2%). In general, it was with a pessimistic perspective that young people in general, particularly girls and university students, understood the new school reality postconfinement, the effects on friendship relations, leisure activities and physical activity. By demonstrating AYA's ability and competence to identify and expose their problems, this study intends to raise awareness of the need for their involvement in the issues that affect them.
