August 23, 2023 – One-year-olds who spent an hour or more of screen time every day were as much as five times more more likely to miss communication skills milestones by age 2, in keeping with a brand new study from Japan.
While research on screen time to this point has shown mixed effects on the event and acquisition of latest skills, including in some cases advantages that trusted what style of programs are viewed, this latest study sought to find out whether specific areas of development are affected by screen time at a young age.
Screen time was defined because the time spent watching television, playing video games, or using mobile phones, tablets or other electronic devices.
The study was published this week within the magazine JAMA Pediatrics. The researchers analyzed data from 7,097 children born in Japan whose moms provided ongoing updates to a database for research purposes. The research program recruited pregnant women between 2013 and 2017 to contribute data about their children.
The researchers analyzed how much time the moms reported their children spent in front of screens every day as one-year-olds and linked this information to the moms' later reports of whether their children had met developmental milestones as two-year-olds. To understand how much time their children spent in front of screens as one-year-olds, moms were asked, “On a typical day, how many hours do you allow your children to watch television, watch DVDs, play video games, play Internet games (including cell phones and tablets), etc.?”
When the youngsters were 2 and 4 years old, the moms were also asked a series of standardized developmental questions called Questionnaire on age groups and development stagesSome communication questions checked out whether the kid imitated a two-word sentence, e.g., “Mommy, eat,” or whether a toddler could point to an actual picture without being shown it, e.g., “Where is the dog?”
The researchers found that when taking a look at a toddler's each day screen time at one yr of age, those that spent an hour or more per day on screens were more more likely to have developmental delays in communication skills as two-year-olds than one-year-olds who spent lower than an hour per day on screens.
Specifically, the study showed that 2-year-olds:
- 61% higher likelihood of developmental delays in communication if children spent 1 to lower than 2 hours a day in front of the screen as one-year-olds
- Children with 2 to lower than 4 hours of each day screen time are twice as more likely to have a communication delay as one-year-olds.
- Five times more more likely to have a developmental delay in communication in the event that they spend 4 or more hours a day in front of a screen
The study also showed that children who spent an hour or more of screen time each day as one-year-olds were more more likely to miss milestones in tremendous motor skills, personal skills and social skills as two-year-olds. However, as four-year-olds, the youngsters weren't more more likely to miss milestones in these areas.
The authors noted that limiting screen time is difficult in the trendy world. The American Academy of Pediatrics (AAP) discourages children under 18 months of age from using screen time apart from video chatting.
“There is sufficient evidence to recommend limiting digital media use for children ages 2 to 5 to no more than one hour per day to give children sufficient time for other activities important to their health and development and to establish media use habits associated with a lower risk of obesity later in life,” the AAP’s guideline states. Media and young minds it says. “In addition, encouraging parents to switch to educational and prosocial content and to engage with their children about technology will help children get the most out of what they see.”
According to the AAP, children as young as 15 months can learn words from touchscreens but have trouble transferring that knowledge to the true world. Two-year-olds can learn words through live video chats with a responsive adult, the AAP reports.
“The most important factor in helping young children learn from commercial media (starting at about 15 months of age) is parents watching the media with them and reteaching the content,” advises the AAP.
