"More time using electronic devices or watching TV among children and young adults was linked with higher cardiometabolic disease risk, including high blood pressure, high cholesterol and insulin resistance, based on data from more than 1,000 participants in Denmark. The association between screen time and cardiometabolic risks was strongest in youth who slept fewer hours, suggesting that screen use may harm health by "stealing" time from sleep, researchers said."
"Researchers said the findings underscore the importance of addressing screen habits among young people as a potential way to protect long-term heart and metabolic health. Screen time tied to early heart and metabolic risks Children and teens who spend many hours on TVs, phones, tablets, computers or gaming systems appear to face higher chances of cardiometabolic problems, such as elevated blood pressure, unfavorable cholesterol levels and insulin resistance."
More recreational screen time correlated with greater cardiovascular and overall cardiometabolic risk among children and adolescents in Danish cohorts of more than 1,000 participants. Higher screen time associated with elevated blood pressure, unfavorable cholesterol profiles and insulin resistance. The association between screen time and cardiometabolic measures was strongest in youth with shorter sleep duration, suggesting that screen use may reduce sleep and thereby worsen cardiometabolic health. Only 29% of U.S. youth ages 2 to 19 had favorable cardiometabolic health in 2013–2018 National Health and Nutrition Examination Survey data, indicating cardiometabolic risk is accruing at younger ages. Addressing screen habits and ensuring adequate sleep in young people may help protect long-term heart and metabolic health.
