Young adults are on their screens now more than ever


The overwhelming majority of Australian adolescents are spending excessive amounts of time glued to their screens, a habit that could put them on a path for developing chronic diseases and physical ailments.

A study of 11-14 year-olds has found nearly 86% of them exceed the national recommended guidelines of no more than two hours of sedentary recreational screen time per day, not including time spent on school work.

The research, published in the Medical Journal of Australia, asked 6,640 year seven students to complete an online survey about their exercise, sedentary recreational screen time, sleep and diet, as well as alcohol and tobacco use.

It found 85.9% of them exceeded the recommended television and electronic device screen time limits, nearly 78% did less than the recommended hour of exercise a day, and 61.3% did not get enough sleep.

It is recommended 13-year-olds get 9-11 hours’ sleep a night, and 14-17 year-olds get 8-10 hours. More than half of the students also reported their diet was poor.

Associate Professor Leigh Tooth, Principal Research Fellow at the University of Queensland, praised the research by Champion and colleagues, which found when it came to screen time, the numbers were getting worse.

“When the government first released screen-time guidelines social media wasn’t such a thing,” she said. Now, just about every child has a smartphone, and they’re getting them younger and younger. It’s here to stay, it’s not possible to ban it, so we have to manage it.”

“If they are going to spend time on screens, then let’s make sure that time is as enriching as possible.”

Assistant Prof Tooth said GPs could play a role in guiding conversations about healthy lifestyles.

“We’re talking about diet, screen time, body weight, physical activity, sleep, substance misuse – they all play a part, and if the balance is wrong, the trajectory th at child can take in terms of their risk for chronic disease development can change,” she said.

Those factors were among the main drivers for chronic disease development, which was happening earlier, sometimes starting in adolescence.

GPs also had an opportunity to raise awareness with parents.

“A child will model their parents. If the parent is on the phone 24 hours a day, not exercising, eating badly, then the child sees that.”
