These just showed up on Ads Of The World, credited to ATHOS\TBWA in Bolivia. Copy says, "A sedentary lifestyle kills like any disease. Change your life for your own life."
The file names indicate that they're some sort of partnership with Bolivia's health ministry, but they are branded only with the Coca-Cola logo and no call to action.
