A recently published study has pointed to the health issues bogging kids, right from obesity to tobacco use, caused due to increased exposure to television and other media.
"The results clearly show that there is a strong correlation between media exposure and long-term negative health effects to children," said Ezekiel Emanuel of the National Institutes of Health, lead researcher on the study.
The study, "Media and Child and Adolescent Health: A Systematic Review," was done by the Yale University School of Medicine, National Institutes of Health, and California Pacific Medical Center and published by Common Sense Media.
It looked at the best studies on media and health from the last 28 years, a total of 173 in all, and found that 80 percent of them showed that greater media exposure led to negative health effects in children and adolescents.
The study examined media exposure and seven health outcomes: tobacco use, early sexual behavior, childhood obesity, attention deficit disorder with hyperactivity, low academic performance, drug use and alcohol use.
"This review is the first ever comprehensive evaluation of the many ways that media impacts children's physical health," said Emanuel, whose brother, Rahm Emanuel, is chief of staff to president-elect Barack Obama.
The strongest link was found between media and obesity with 86 percent of 73 studies finding a strong relationship between increased screen time and obesity.
Eight-eight percent of 24 studies examining media and tobacco use found a statistically significant relationship between increased media exposure and an increase in smoking at an early age.
