San Francisco: Babies aged one who spent more than four hours a day looking at screens such as televisions, computers, tablets, or smartphones experienced developmental delays in communication and problem-solving skills at ages two and four, a new study has shown.
According to a study published in the journal JAMA Pediatrics, one-year-olds who were exposed to more screen time than their peers demonstrated delays in the development of fine motor and personal and social skills at the age of two. The study included over 7,000 Japanese children and measured how many hours per day children used screens at age one based on reports from their mothers.
The researchers also looked into how the toddlers performed on various developmental tests between the age of two and four. The study discovered that by the age of two, children who had spent up to four hours per day on screens were up to three times more likely to experience developmental delays in communication and problem-solving skills.
"We observed that screen time for children aged one year was associated with the fine motor and personal and social skills domains at age 2 years, however, this association was not confirmed at age 4 years. There are two possible hypotheses for this finding. One hypothesis is that the developmental delay of fine motor and personal and social skills for children aged 2 years caught up with them at age 4 years," the researchers said.
