Thursday, October 29, 2015 (HealthDay News) – A new study links excessive television viewing with some of the leading causes of death in the US
.
The 92 percent of Americans have a television at home, according to background information in the study. And 80 percent of adult Americans watch an average of three hours of TV a day, which makes up more than half of their leisure time.
“We know that watching television is the behavior of sedentary leisure time more prevalent, and our working hypothesis is that it is an indicator of physical inactivity in general, “explained study author Sarah Keadle member of Cancer Prevention National Cancer Institute US. UU.
“In this context, our results match growing body of research suggesting that sitting too long can have several different adverse health effects,” said Keadle.
In the study, researchers followed more than 221,000 people from 50-71 years of age who had no chronic disease at baseline, which lasted nearly 15 years. All were followed until death or until December 2011.
The more television watched, the more likely the elderly were dying of diseases such as heart disease, cancer, diabetes, influenza / pneumonia, Parkinson’s disease and liver disease, the researchers found.
Compared with those who watched less than one hour of television per day, the risk of dying during the study period was 15 percent higher among those who saw three to four hours of TV a day, and 47 percent higher among those who watched seven or more hours a day, according to the findings.
Even after the researchers took into account other factors risk (such as smoking, drinking alcohol, calorie intake and health problems) the association between television viewing and increased risk of death during the study period remained.
But the association observed in the study does not mean that watching too much TV causes death by these diseases.
The increased risk of death associated with watching television very often observed in both active and inactive people study the report which was published online Oct. 27 in the journal American Journal of Preventive Medicine .
“Although we find that exercise does not eliminate all the risks associated with watching television for long periods, certainly for those who wish to reduce their sedentary use of television, the exercise would be the first choice to replace that time previously spent inactive “Keadle said in a news release from the journal.
The findings extend the growing evidence that spending too much time sitting is a threat to health.
“Seniors are the most television are all US demographic groups. UU. “Keadle said.” Given the increasing age of the population, the high prevalence of television on leisure time and the wide variety of mortality results in the risk appears to increase, watching television for long periods it could be a more important for public health interventions than had been recognized “objective.
