On this encore episode, we revisit and update one of the most-read articles on the CMAJ website.The article is titled, “Smartphones, social media use, and youth mental health.” It reviews the extensive literature linking poor mental health in adolescents with smartphone and social media use. The article details a variety of studies that implicate smartphone and social media use in increased mental distress, self-injurious behaviour, and suicidality among youth. It also indicates that there's a dose-response relationship, with the effects appearing to be most pronounced among girls.The lead author of the paper is Dr. Elia Abi-Jaoude. He is a psychiatrist and researcher at The Hospital for Sick Children in Toronto. He delves into recent research exploring how social media and smartphone use negatively impact the mental health of young individuals.Later in the episode, Dr. Michelle Ponti offers practical tips that physicians can provide parents to effectively manage their children's smartphone and social media use. Dr. Ponti is a paediatrician in London, Ontario, and Chair of the Digital Health Task Force for the Canadian Paediatric Society.Join us as we explore medical solutions that address the urgent need to change healthcare.
