From Johns Hopkins University: Daily television viewing for two or more hours in early childhood can lead to behavioral problems and poor social skills, according to a study of children 2.5 to 5.5 years of age conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. More importantly, heavy television viewing that decreased over time was not associated with behavior or social problems. The American Academy of Pediatrics recommends that children under age 2 watch no television while children age 2 and older are limited to no more than two hours of daily viewing. "A number of studies have demonstrated negative effects of heavy television viewing. However, timing of exposure is an important consideration as reducing viewing to acceptable levels can reduce the risk of behavioral and social problems," said Kamila Mistry, MPH, lead author of the study and a doctoral candidate in the Bloomberg School's Department of Population, Family and Reproductive Health. For the study, the research team analyzed data for 2,707 children collected from the Healthy Steps for Young Children national evaluation. Sixteen percent of parents reported that their children watched two hours or more of television daily at 2.5 years of age (early exposure), while 15 percent reported that their children watched two hours or more of television daily at 5.5 years of age (concurrent exposure). One in five parents reported that their children watched two hours or more of television daily at both 2.5 years and at 5.5 years of age (sustained exposure). "It is vital for clinicians to emphasize the importance of reducing television viewing in early childhood among those children with early use."
