Children who spend hours watching television or playing video games are doing worse at school, scientists claim.

In the largest study of its kind, the habits of nearly half a million children around the world were analyzed.

In general, the time spent on screens, including cell phones, did not affect academic performance.

However, children who chose to watch TV or play video games in most of their free time had worse grades in school, the study said.

The study is due to the fact that within the coming year the guidelines of the British government are expected to set limits on the screening time of children in an attempt to protect their mental health.

Lead author Dr. Mireia Adelantado-Renau, of Jaume I University in Castellon, Spain: & Each screen-based activity must be analyzed separately for its academic performance.

& # 39; Education and health professionals should consider monitoring and reduction to improve the academic performance of children and adolescents exposed to these activities. & # 39;

The study, published in JAMA Pediatrics, assessed 58 studies from 23 countries involving 480,000 young people under the age of 18.

The team also merged data from 30 of those studies, including 106,000 participants, comparing the use of screen media and academic performance.

Academic performance was measured by analyzing their language and maths abilities and composite scores.

A composite score is an average of four test scores in English, mathematics, reading and science, ranging from one to 36.

Screen time included surfing the internet, using mobile phones, watching TV, and playing video games.

Television and video games were linked to lower composite scores, while television appeared to negatively influence language and math skills.

Further analysis suggested that these screen-based activities have a greater effect on adolescents than children.

Watching television can reduce how many young people use their brains compared to whether they were exercising, the researchers said.

& # 39; In addition, it has been shown that excessive TV viewing time in children reduces attention and cognitive functioning and increases behavioral problems and unhealthy eating habits, which can also damage academic results, & # 39; said the authors.

On the other hand, video games can cause psychological and behavioral problems, which implies the education of a child.

Dr. Adelantado-Renau said the research was important given the increasing time spent on screen-based activities in children and adolescents.

In February this year, British officers said that cell phones should be banned from the dining table and bedtime.

Dame Sally Davies said that a code of conduct was absolutely necessary to keep children safe after Molly Russell's suicide.

Links were made between the teenager's death and her exposure to harmful material on Instagram.

The findings of this study did not support previous studies that found that the total time spent on fencing has a negative effect on numbers or the development of a child.

Canadian researchers discovered that adolescents who spent more than seven hours a day on overall screen media were 40 percent less likely to achieve high academic performance.

And toddlers who use screens for more than two hours a day are seven times more likely to develop ADHD, according to scientists from the University of Alberta.

The screen time has a & # 39; significant impact & # 39; on the development of the child, the researchers said. Both studies were published in the journal PLOS ONE.

HOW CAN STUFF TOO MANY TIME AT SCREENS INFLUENCING CHILDREN?

Research has shown that spending too much time watching screens – for example smartphones, tablets, computers and televisions – can be harmful to children's intelligence, sleep, mental health and vision.

A 2018 study by the CHEO Research Institute in Ottawa showed that eight to eleven year olds performed five percent worse on brain tests than their peers when they watched screens for two hours a day.

This, they suggested, may be because looking at screens is not as stimulating as reading, and could disrupt vital sleep.

Disrupted sleep was also the focus of a warning from the British Royal College of Pediatrics and Child Health earlier this year, when it advised children not to use screens before bedtime.

The RCPCH said that high levels of screen time are linked to a less healthy diet, a sedentary lifestyle, and poorer mental health.

Dr. Max Davie, a health officer, said, "Parents should have control over their own screen time if they get control over the family's screen time. It is much easier to be authoritative if you practice what you preach. & # 39;

Dr. Langis Michaud, professor of optometry at the University of Montreal, registered The conversation in February: & # 39; Since the introduction of the smartphone in 2007, a rapid increase in visual problems has been observed.

& # 39; Although the device itself does not emit harmful radiation, the user must read the screen at a distance of 20 cm instead of the normal distance of 45 cm to 50 cm.

& # 39; It has been suggested that this short distance increases the risk of developing myopia by eight times, especially if both parents are myopic. & # 39;
