My understanding is walking rather than than driving for instance is NOT a solution to this specific issue (It's great for other reasons).
It is in part, as in you might sit for 13 hours a day so 30 mins less sitting makes you 3% better off but really it's not the solution. Similarly to getting up and walking around, if you do it 5 mins ever hour that's 4% better off.
My understanding is these studies are saying to make change you need to stop sitting for large periods of time (ie reduce by 50+%), if you don't want to die/become crippled early.
