This systematic narrative review examined the relationships between SNS and depressive and anxiety symptoms in the child and adolescent population (5-18years). Four databases were searched, and all articles between January 2005 and March 2019 were identified. Increased time spent or frequency of SNS use, and problematic and addictive behaviour on SNS were significantly associated with higher levels of depressive symptoms. Two cross-sectional studies found that increased time spent or frequency of SNS use and higher levels of investment on SNS were significantly associated with higher levels of anxiety symptoms. However, other potential confounding factors could explain the relationship between SNS and depressive and anxiety symptoms, including perceived social support, social comparison and fear of missivelopment of emotional regulation in young people. These findings help to inform clinicians and educators in targeting vulnerable young people who are at risk of developing mental health problems.Children and adolescents spend increasingly large parts of their social life connecting with each other via social networks sites. While this is clearly an achievement and may have helped many of them during difficult COVID-19 lock downs, there is an ongoing political and scientific debate around the potential harm that (excessive) social media use may pose on young individuals. This editorial highlights a systematic review that was published on the topic of social media use and child and adolescent mental health, and sets the results of this review into a current research and public health perspective.Ferroelectric materials usually undergo decay with particle size decreasing into the nanoscale.
