Adults with heart disease were excluded from the study, and the results were unchanged even after researchers adjusted for factors like exercise habit, waist circumference, diet and smoking. Not surprisingly, the researchers recommended reducing time spent watching television, and being sedentary.
Don’t be too smug if you don’t own a television or even watch much TV. In interviews, the researchers made clear it wasn’t the shows or even the actual watching of TV that shaved years off of people’s lives, it was the sitting.
They contend that their results would have remained the same whether study participants were reading a book, doing needlepoint, or working at a computer. Even jogging 5 miles every morning before work wouldn’t skew these results. If you spend the remainder of the day sitting, your risk rises just the same.
