The impact of COVID-19 lockdown on children's and adolescents' mental health in Greece.

The aim of the study was to investigate the impact of the COVID-19 lockdown on children's and adolescents' mental health in Greece during the lockdown of spring 2020. A cross-sectional survey of 1232 Greek parents was conducted in spring 2020. 35.1% of parents reported that their children's psychological health was significantly affected. Parental unemployment, limited opportunity for tele-work and deteriorating psychological health, increased family conflicts and children's pre-existing physical health conditions were all significantly associated with mental health impact. Children and adolescents may experience adverse mental health effects due to the COVID-19 pandemic.
