Preliminary results from a new US study suggest that teens who spend a large amount of their time in front of a screen have higher risk of insomnia symptoms and shorter sleep duration, which in turns leads to a greater risk of depression. 

Carried out by researchers at Stony Brook University, Penn State University, and University of Wisconsin-Madison, the study looked at data on 2,865 adolescents with an average age of 15.63 years who were taking part in the Fragile Families and Child Wellbeing Study's teen survey.
