This association was mediated by greater emotional regulation difficulties and anxious and depressive symptoms. There were also positive associations across studies between PSU and several eating disorder-related outcomes, including food addiction, body dissatisfaction, uncontrolled eating, and emotional overeating, though most outcomes were rated low-certainty. There was a consistent relationship between daily smartphone screen time and higher eating disorder psychopathology."It is apparent from our study that, even for people without a diagnosis of an eating disorder, the overuse of a smartphone is associated with poor body satisfaction and altered eating behaviors, and is a potential source of distress," senior author Ben Carter, Ph.D., also from King's College, said in a statement.Abstract/Full Text.Sign up for our weekly HealthDay newsletter
