Almost two-thirds of respondents offer workers financial rewards to encourage them to participate in health programs, but tougher requirements are planned. About 16 percent of companies now require employees to reach certain targets, such as healthy blood pressure or weight goals, to earn rewards, and another 31 percent are considering the strategy for 2014. Interest is growing in expanding financial incentives to include spouses, with 59 percent of employers anticipating doing so by 2014, up from 23 percent that did so in 2012.
