- Risk for venous thromboembolism (VTE) may rise with increased TV viewing.
Why this matters
- This is the first study in a western population regarding the effect of TV viewing on VTE risk in the legs, arms, pelvis, and lungs.
- 15,158 middle-aged (45-64 y) participants in the Atherosclerosis Risk in Communities Study were assessed by researchers at the University of Vermont.
- Risk of developing a VTE for the first time was 1.7 times higher in those who reported they watch TV “very often” compared with those who watch TV “never or seldom.”
- Risk was 1.8 times higher in participants who met recommended guidelines for physical activity and reported watching TV “very often,” compared with those who reported watching TV “never or seldom.”
- Risk increased with more TV viewing both for life-threatening clots in the extremities and those in the lungs.
- While obesity was more common in people who watched more TV, in the study only about 25% of the increased risk could be explained by the presence of obesity.
