Amid the ongoing health care debate, employers, providers and consumers alike agree that reducing the cost of health care should be a central goal of reform efforts. One of the most effective ways to reduce health care costs is to focus on early detection and prevention of disease.

To that end, a growing number of employers sponsor corporate wellness programs. These initiatives typically encourage exercise and healthy eating, provide resources to help employees improve their health, and include health risk assessments–surveys that assess workers’ risk for various illnesses and direct them to appropriate preventive care or screening.
