Television Watching and Telomere Length Among Adults in Southwest China

Peer-Reviewed Scientific Journal:
American Journal Of Public Health

Size of study:
518 adults ages 20-70

Summary
This study looked at whether hours spent watching TV was associated with telomere length in a group of 518 adults ages 20-79. Data on time of sedentary behavior, screen-based sedentary behavior (including television watching and computer or phone use), moderate to vigorous physical activity, and dietary intake were collected over the course of two years. Also, height, weight, and waist circumference were measured to calculate body mass index and percentage of body fat.

The researchers found that the hours of screen based viewing were inversely correlated to telomere length. In other words, the more time spent sitting and watching a screen, the shorter the subjects’ telomere length.

  • Was it the length of time watching…or the fact that length of continual sedentary (immobility) caused a deterioration of functionality…from the cells thru to the organs?
