From Axios:
Preteens who own smartphones are likelier to have depression, obesity and insufficient sleep than their peers, according to a new University of Pennsylvania-led study.
What they found: Kids who owned a smartphone at age 12 were found to have about 31% higher odds of depression, 40% higher odds of obesity and 62% higher odds of insufficient sleep than their peers who didn’t have one. The intrigue: The results seem specific to owning a smartphone, the researchers write, since their models accounted for owning other devices like tablets and smartwatches.
