The Journal article follows the efforts of Syngenta, a Swiss company with a strong presence in the U.S. After discovering that spouses' medical claims were higher than employees' (by almost 30%!), they started encouraging spouses to participate in biometric screenings and health risk assessments.
Serious health conditions have been uncovered through the screenings, and some employees have lost weight and made lifestyle changes as a result of the information they received. According to Syngenta, their wellness program has helped keep the cost of health care inflation below the national average.
Given that millions of people depend on their spouses for health coverage, it makes sense to include spouses and partners in wellness programs. After all, as we've argued many times, people are more likely to make lasting changes if they have support--both at home and at work.
