News release: “Full-time workers in the U.S. who are overweight or obese and have other chronic health conditions miss an estimated 450 million additional days of work each year compared with healthy workers — resulting in an estimated cost of more than $153 billion in lost productivity annually. These findings are based on Gallup-Healthways Well-Being Index data collected between Jan. 2 and Oct. 2, 2011. Gallup surveyed 109,875 full-time employees — those who work at least 30 hours per week — during this time period.”
