Children watch a lot of phones and TV, increasing the risk of heart disease

Research has found that a child who spends an additional three hours a day on screen has a 25-50% higher risk of heart disease and metabolic disorders than their peers.

Children who spend too much time sitting in front of screens, whether phones or televisions, will have a higher risk of heart-related diseases and metabolic disorders, according to a study by Danish scientists published on August 6.

The study tracked the electronic device usage and sleep habits of more than 1,000 adolescents aged 10 to 18 years old to analyze the association between device use and cardiovascular-metabolic risk factors.

The results show that children and adolescents who spend too much time in front of screens and electronic devices are at higher risk of cardiovascular and metabolic diseases, such as high blood pressure, high cholesterol and insulin resistance, or diabetes.

Specifically, Mr. David Horner, lead author and researcher at the University of Copenhagen, said that a child exposed to screens for an additional 3 hours/day will have a 25-50% higher risk of getting sick than their peers.

If this were to occur across the entire pediatric population, it would result in a significant change in cardiovascular disease risk early in life that could persist into adulthood.

Researchers are still debating the negative effects of electronic device use on children and teenagers. However, there is a general consensus that this age group is more susceptible than adults.

The study was published in the Journal of the American Heart Association.
