-More You Watch TV, More You Will be at Risk of Eight Leading Causes of Deaths

Researchers at the National Cancer Institute have found that viewing too much of TV increases risks of developing large number of diseases like diabetes, influenza/pneumonia, Parkinson's disease, and liver disease. The recent study published in the Milwaukee Journal Sentinel throws light on the link between increased hours of TV watching and eight of the leading causes of death in the United States.

Researchers found that about 92% of Americans have TV at their homes, which consumes more than 50% of their available leisure time lacking more physical activities. Sarah K. Keadle, lead investigator of the study, said the findings fit best within a growing body of research suggesting that too much sitting causes adverse effects on health of people. On analyzing data from more than 221,000 individuals aged 50-71 years old, researchers found 15% increased chances of death from any cause in participants who watched three to four hours of TV daily. The risks of death were 47% in participants who watched seven or more hours of TV daily.

Researchers even considered other factors like caloric and alcohol intake, smoking, and the health status of the population, which might even explain the association observed. But, they found no change in their results even after controlling these factors in participants. Keadle said that the first step to reduce the risks associated with the prolonged TV viewing is to do regular exercise. Researchers said that still a lot of research is needed to explore connection between TV viewing and mortality. Also, there is need to find the results of same associations in contexts of driving, working or doing other sedentary leisure-time activities.
