So many studies confuse correlation with causation. Can this one be trusted? After all, those more likely to be disabled are also more likely to avoid moving around...because it causes pain.
what do they mean by disabled? if this were the case—the more sedentary you are, the more likely you are to be disabled after the age of 60, regardless of amount of exercise (or moderate exercise?)—it seems we would have more disabled people over the age of 60...
See above posts on the percentage of FReepers who quickly perceived the questionable nature of this conclusion. Maybe they should do a study on FReepers.
Also, since 13 sedentary hours a day means you are 50 percent more likely to be disabled than one who sits for 12 hours a day, then what does this mean the latter are 50% more likely to be disabled than one who sits for 11 hours a day?
Usually the study will accurately describe the results as a correlation but a reporter will report it as causation.
