Children who are given a smartphone before the age of 12 face a higher likelihood of developing health issues, as indicated by a recent study. The research, published in the journal Pediatrics on December 1, revealed that kids who owned smartphones at age 12 were at a 1.3 times higher risk of depression, a 1.6 times higher risk of insufficient sleep, and a 1.4 times higher risk of obesity compared to their counterparts without smartphones. The study, conducted by researchers from Children’s Hospital Philadelphia, the University of California at Berkeley, and Columbia University, analysed data from over 10,500 participants in the Adolescent Brain Cognitive Development (ABCD) Study – the largest U.S. study on brain development and child health.

Lead author of the Pediatrics journal study, Dr. Ran Barzilay, a child-adolescent psychiatrist at Children’s Hospital of Philadelphia, highlighted that over 60% of the children studied had their own smartphones by the age of 12, with the median age for smartphone acquisition being 11 years old. The study focused on data collected when the children were aged between 12 and 13 years, gathered from 2018 to 2021. The objective of the study was to investigate the associations between smartphone ownership, age of smartphone acquisition, and health outcomes like depression, obesity, and insufficient sleep in early adolescence. Dr. Barzilay emphasised the importance of monitoring children’s smartphone use’s impact on their lifestyle and well-being, urging parents to regularly engage with their children to understand how smartphone usage may be affecting them.
Addressing the decision-making process behind the study, Dr. Barzilay acknowledged the existing recommendations to delay smartphone acquisition for children but noted the lack of substantial data supporting this suggestion. He emphasised the significance of evidence-based practices in making informed decisions that influence children’s health in the digital age. Notably, the rise in smartphone usage among teenagers in the U.S. was highlighted by Dr. Barzilay, who cited Pew Research Center data indicating that 95% of teenagers aged 13 to 17 owned smartphones in 2024. The survey also revealed that smartphone ownership was prevalent among younger children, with nearly a third of 8 to 10-year-olds and over half of 11 to 12-year-olds having smartphones.
The correlation between smartphone use and adverse health effects has drawn attention from experts and researchers alike. Social psychologist Jonathan Haidt referenced in his 2024 book “The Anxious Generation” the concerning impact of smartphones on children’s mental health, particularly noting a surge in anxiety and depressive disorders coinciding with the widespread adoption of smartphones among teens. Dr. Barzilay’s study contributes valuable evidence to guide parents and policymakers in making informed decisions regarding children’s smartphone use, underlining the need to balance the potential risks and benefits of early smartphone ownership. As smartphones become increasingly integrated into daily life, understanding their impact on young users remains a critical area of research and concern.
In conclusion, the increased prevalence of smartphone ownership among children before the age of 12 is associated with a higher risk of health challenges such as depression, obesity, and insufficient sleep. The findings underscore the importance of thoughtful consideration and monitoring of children’s smartphone usage to safeguard their well-being and overall health. As technology continues to play a central role in children’s lives, balancing the benefits and risks of early smartphone access is essential for promoting a healthy and thriving generation.
