Although the lockdown during the pandemic negatively influenced the health of all age groups ( Eedera et al, 2022 ; Haque et al, 2022 ; Katewongsa et al, 2021 ; Luijten et al, 2021 ; Marcos-Pardo et al, 2022 ; Morgul et al, 2020 ; Runacres et al, 2021 ; Tulchin-Francis et al, 2021 ; Wilson et al, 2020 ),there was evidence that adolescents were more severely affected by the COVID-19-related public health actions ( Elvén et al, 2022 ; D. C. Paterson et al, 2021 ; Wilke et al, 2021 ; Xiang et al, 2020 ) and further evidence suggests that adolescents were more affected than younger or older adults, although the latter finding is not universal ( Elvén et al, 2022 ; Runacres et al, 2021 ; Wilke et al, 2021 ). In the literature, it has been emphasized that adolescents are a vulnerable and key age group that deserves more research attention ( Runacres et al, 2021 ).…”
