ONE in three kids are dangerously addicted to smartphones — and suffer anxiety when separated from them, a major study suggests.
Experts claim a “significant minority” of young people are glued to their devices.
In the first study of its kind, psychiatrists link uncontrolled smartphone use to a host of mental health problems.
It reveals teens and young adults stuck to their devices were three times more likely to suffer from depression or anxiety.
And they saw their risk of poor sleep double.
The findings come from analysis of 41 international studies — including UK data — involving nearly 42,000 people as young as 11.
It shows ten to 30 per cent of participants were “problematic users” with clear signs of smartphone addiction — with an average of 23 per cent across all the reports.
King’s College London said the majority of participants were in their teens and early 20s.
The study is published in the journal BMC Psychiatry.
Experts say common mental disorders have risen in young Brits over the past decade — at the same time as smartphone usage has rocketed.
Figures show around 95 per cent of 16 to 24-year-olds now own their own device.
Researcher Dr Nicola Kalk said spending too much time on smartphones could lead to missing work or school, wrist and neck pain, and anxiety when devices are taken away.
She said: “A significant minority of teenagers and young people do not have a healthy balance when it comes to smartphone usage.”
