A recent study published in the journal Pediatrics indicates that children who obtain smartphones by age 12 are at a heightened risk for depression, obesity, and lack of sleep. The research team discovered that the earlier a child receives a smartphone, the greater their risk of facing these health issues.

Dr. Ran Barzilay, the lead author of the study and a child and adolescent psychiatrist at Children's Hospital of Philadelphia, emphasized the importance of delaying smartphone ownership among children. He noted that many experts advocate for postponing the introduction of smartphones to young users, particularly as children approach adolescence.
The research, involving over 10,500 participants from the Adolescent Brain Cognitive Development Study, analyzed data from children aged 9 to 16 collected between 2016 and 2022. The study explored the impact of smartphone ownership and the age at which children received their first device on their health outcomes.
Findings revealed that 12-year-olds who had smartphones were 1.3 times more likely to experience depression, 1.4 times more likely to be obese, and 1.6 times more likely to suffer from insufficient sleep compared to their peers without smartphones. The risk further increased by approximately 10% for each year younger a child was when acquiring their first smartphone, beginning as early as age 4.
Additionally, the research indicated that 13-year-olds who obtained a smartphone after age 12 also exhibited poorer mental health and sleep quality. Dr. Barzilay highlighted that while the study shows correlation rather than causation, it reinforces evidence linking smartphone use to negative health outcomes in children.
The American Psychological Association also stresses the need to reduce screen time due to its association with socio-emotional issues in children. The authors recommend that parents and pediatricians engage in discussions about whether children are ready for smartphone ownership.
Dr. Barzilay clarified that the study is not intended to assign blame to parents who provide their children with smartphones at a young age. He acknowledged that smartphones can foster connectivity and access to information but advised parents to implement guidelines, such as restricting smartphone use in bedrooms at night and encouraging activities that don't involve phones.
As for Dr. Barzilay's own nine-year-old, he stated that they will "not be getting a phone anytime soon," reflecting his commitment to these recommendations. Dr. Amanda Wang from ABC News contributed to this report.
