A growing number of large employers are taking action to combat chronic health conditions to mitigate costs and improve the health of their workforce, according to a new survey by Hewitt Associates. Their efforts go beyond general condition management programs to pinpoint the most prevalent chronic illnesses among their employees. Three-quarters of the 343 large U.S. employers surveyed are targeting diabetes, 69% are targeting cardiovascular disease, 56% are targeting asthma and 32% are targeting depression. However, only a small percentage of eligible workers actually participate in these condition management programs, and their long-term success will depend on changes in participant behavior, Hewitt said.
