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.

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?

Excellent observation: “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?”

I would bet that those sit for 12 hours a day and were in better health might have walked for an hour a day at a time or two 30 minute walks per day.
