Sử dụng điện thoại thông minh sớm liên kết với nguy cơ tác động đến sức khỏe tâm thần suốt đời cho trẻ em, cảnh báo từ nghiên cứu toàn cầu

A sweeping global study has found that children who own smartphones before the age of 13 are at significantly higher risk for mental health problems later in life. The research, which surveyed nearly 2 million people across more than 160 countries, links early smartphone access to increased rates of depression, suicidal thoughts, aggression, and low self-worth, especially among girls. Experts warn that excessive screen time and exposure to social media can disrupt sleep, emotional regulation, and healthy brain development in preteens. The findings have prompted calls for parents to delay giving smartphones to children and for policymakers to consider age restrictions. Overall, the study highlights the urgent need for greater awareness and action to protect young minds from the potential harms of early digital device use.
