UCSF researchers tracking nearly 9,000 US adolescents found smartphone owners at 12 had a 36% higher chance of reporting any eating-disorder symptom.

King's College London researchers linked more daily steps in 5,515 US adolescents to fewer anxiety and depression symptoms a year later. The study is observational, so step counts become a cheap marker to track, though it cannot yet show that adding steps lowers symptoms.

King's College London tracked lockable pouches through a school year in eight Northern Ireland secondary schools and found phone use down and teachers pleased, while pupil mental health measures hardly moved. The design explains some of the gap.
