Excessive Screen Time Linked to Increased Cardiometabolic Risks in Youth

Recent findings from a comprehensive study in Denmark have brought to light the concerning link between excessive screen time and elevated risks of cardiometabolic diseases in children and young adults. The research, involving over 1,000 participants, was published in the Journal of the American Heart Association, revealing that each additional hour spent in front of electronic devices correlates with an increase in cardiometabolic risk scores. These scores are indicators of potential health issues such as high blood pressure, high cholesterol, and insulin resistance.

Led by David Horner, M.D., PhD., from the Copenhagen Prospective Studies on Asthma in Childhood (COPSAC) at the University of Copenhagen, the study analyzed data from two distinct groups of young individuals. It uncovered that the cumulative effect of screen time could have significant implications for long-term heart and metabolic health. Furthermore, the research identified insufficient sleep as a factor that worsens the relationship between screen time and cardiometabolic risk, underscoring the importance of adequate rest in mitigating these health risks.

Amanda Marma Perak, M.D., M.S.CI., FAHA, chair of the American Heart Association’s Young Hearts Cardiovascular Disease Prevention Committee, advocates for modeling healthy screen use behaviors for children and teens. She recommends practical measures for families, such as scheduling screen time earlier in the day and ensuring sufficient sleep, to help lower the potential health risks. This study not only provides critical insights for parents and healthcare providers but also paves the way for further research into the biological effects of screen time and its lasting impact on heart health.
