Although millennials place a lower priority on medical care than other generations, they also expect employers to play an active role in supporting their overall health and well-being.

That is one of several conclusions that Aon Hewitt reached after analyzing the "2014 Consumer Health Mindset" report, a joint survey of more than 2,700 U.S. employees and their dependents.

• Fifty-four percent of millennials have had a physical in the past year.
• Thirty-nine percent said preventive care is important to remaining healthy.
• Twenty-one percent are likely to participate in a healthy eating or weight management program.
• However, 63 percent are likely to engage in regular exercise, the highest percentage of any generation surveyed.

What does this generation expect from employers? Fifty-three percent are more open to having their direct manager play an active role in encouraging them to get and stay healthy, and 16 percent are likely to participate in an employee assistance program.

"Given their younger age, most millennials are relatively healthy, so they may not feel a sense of urgency to go to the doctor regularly or eat a well-balanced diet," said Ray Baumruk, employee research leader at Aon Hewitt. "However, the lack of health prevention and maintenance when they're young may lead to greater health risks as they get older.
