Nine million young people. 121 reviews. What does the evidence tell us about digital technology and children’s health?
A major new three-paper series in The Lancet Group, Digital Determinants of Health, examines how digital environments shape health and why protecting children and young people must become a public health priority.
An umbrella review drawing on 121 reviews and covering approximately 9 million people under 25 found consistent associations between digital media use and adverse outcomes, including mental health difficulties, sleep problems and reduced physical activity.
The series raises a question that goes beyond screen time alone.
What responsibility should technology companies bear for the health consequences of the environments they create?
The authors highlight the role of digital design, commercial business models and inadequate governance in shaping health risks.
Their recommendations include mandatory health-risk assessments before digital products reach the market, stronger corporate accountability and international standards for protecting health.
For Health Professionals for Safer Screens, these findings reinforce a central concern: responsibility for protecting children cannot rest solely with parents, teachers or individual clinicians.
As health professionals, we are increasingly concerned about the cumulative impact of children’s digital environments on their physical health, development and wellbeing.
Digital technology can offer genuine benefits. But those benefits must be considered alongside the evidence of potential harm, with children’s health and safety embedded in decisions about design, access and use.
We need to move from responding to harm to preventing it.
