Aug. 19, 2003 -- Obese women may be more likely to develop breast cancer largely because their bodies produce more estrogen than thin women do. New research suggests that the increase in breast cancer risk faced by obese postmenopausal women may largely be due to higher levels of estrogens circulating in their bodies.
The effects of obesity on worker productivity are high: Obese men take 5.9 more sick days per year and obese women take 9.4 more sick days per year than do their healthy counterparts. This absenteeism costs employers up to $6.4 billion per year and therefore has serious implications on our economyâs overall health.
