More employers than ever are embracing wellness programs, finds a Willis report.

Sixty percent of the 1,600 employers surveyed by Willis said they have some form of wellness program in place, up from 43 percent in 2010. And the majority of businesses with programs in place are looking to expand and invest in them.

"Wellness programs continue to evolve and it is encouraging to see more organizations initiate programs despite economic pressures and continuing challenges in accurately measuring outcomes and results," says Jennifer Price, senior health outcomes consultant at Willis.
