Longer children pass through device screens (such as smartphones and tablets), the worse their development will be in childhood years later. This is a study recently published in the JAMA Pediatrics period, directly associating screen time for children between 2 and 3 years of age in their 3 to 5 year range.
When we talk about "development", in this case, we talk about things like communication skills, driving skills, problem solving skills and social skills. And it indicates that this development is slower than normal, it can be identified in activities such as stacking a toy above the other.
For children 2 to 5 years of age, the American Academy of Pediatrics recommends limits to the use of devices with screens, with only one hour per day. In the study, children had a screen of two to three hours a day and, according to Sheri Madigan, an assistant professor and president of child development research at the University of Calgary, "a larger screen display at 2 and 3 year olds is associated with delaying children meeting development goals at 3 and 5 years of age. " For Madigan, "this study shows that when used too much, screen time can have consequences for the development of children."
At the time of considering older children, the American Academy of Pediatrics points out that both children and adolescents need at least eight hours of sleep a day, plus an hour of physical activity every day. However, a study conducted in 2017 by Common Sense Media found that most children in the United States spend a total of five to seven hours a day in front of a screen, which includes watching television, using a computer and play video games. And as it is known that the blue light emitted by the screens spoils the dream, the American young people do not have a sufficient quality of sound for their healthy development, a reality that can be similar in Brazil.
Returning to the study, although it does not say that leaving young children with a cell phone is a guarantee of poor development in the coming years, it is the first of the kind that relates these two things. However, the new study offers a vision of how technology impacts the development of youth over time, and the good news is that parents are able to control the time their children pass in front of the screens in general .
