03.12.2025 | Bulgaria

Smartphone use in pre-adolescent children is associated with obesity, depression, and sleep problems, according to a study by the American Academy of Pediatrics. The study examines 10,000 cases and shows that early acquisition of a smartphone is linked to an increased risk of these issues. Controlled access from parents improves outcomes.

The use of smartphones by children in prepubescent age leads to obesity, depression, and sleep deprivation. This was reported by UPI, citing a study by the American Academy of Pediatrics.

Within the framework of the study, scientists examined 10,000 individual cases. They distinguished those children who received a smartphone before the age of 12, and those who got their smartphone later, already as teenagers, BTA writes.

Among the youngest participants in the study, scientists observed 31% with an increased risk of depression, 40% with a tendency to obesity. And 62% for whom sleep is likely insufficient, UPI points out.

The study shows better results in children whose access to a smartphone is controlled by their parents. Who have set the limits for when and how much to use the device.

The results of the study were published just a day before the discussion of legislative changes related to the better protection of children in the virtual space. Among these changes is the so-called Child Online Protection Act (Kids Online Safety Act, or KOSA). It was not adopted last year, UPI also recalls.
