Almost 30 per cent of children failed to meet any of the recommendations, more than 40 per cent met only one, a quarter met two, and only five per cent conformed to all three.

Overall, only 5 percent of the children in the study met all three recommendations on sleep, screen time, and physical activity while 30 percent met none of the recommendations.

In order to ensure good cognitive development in children, the Canadian 24-hour Movement Guidelines provided the following recommendations - nine to eleven hours of sleep, less than two hours of recreational screen time, and at least one hour of physical activity on a daily basis.

To improve children's cognitive skills such as problem solving, memory and attention, their screen time should be limited to less than two hours a day.

Dr. Eduardo Esteban Bustamante, an assistant professor of kinesiology and nutrition at the University of IL at Chicago who was not directly involved in the research, suggested that the study's findings about screen time may reflect interruption of important childhood growth cycles involving stress related to physical activity and recovery from sleep.

Letting children spend more than two hours a day on their phones could damage their brain power, a study has found.

The researchers found that as each recommendation was met by a participant, there was a positive association with global cognition, which includes memory, attention, processing speed and language.

The strongest link was between meeting...

Researchers said that parents should try to limit their offspring's recreational screen time, including periods playing video games, using social media and watching television.

It can lead to poorer quality sleep, which can harm a child's development.

The more health guidelines the child met, the better they performed on the cognition test, the findings in The Lancet Child & Adolescent Health journal showed. "Based on our findings, paediatricians, parents, educators and policymakers should promote limiting recreation screen time and prioritising healthy sleep routines during childhood and adolescence".

The study concluded that the children's brain development was better with each guideline respected.

"We really had an opportunity here to look at how meeting each of these guidelines and meeting all of the guidelines relate to cognition in a large sample of American children".

She suggested that future research could benefit from using data collection methods that provide more precise results than questionnaires which rely on self-reported information.
