Which Comes First — Better Health or Better Job Performance?


Better Health or Better Job PerformanceThere’s a strong link between better health and better job performance, according to a study by HCMS Group.

People who rated in the top 20% on year-end performance reviews also had the lowest medical costs and the lowest health risk scores, HCMS researchers found. The analysis covered several thousand professional workers in the HCMS database over 12 months. The performance evaluation system classified the group in three performance bands—the lower 20%, middle 60%, and upper 20%.

There are two ways of looking at the findings. One is that high job performance correlates with a high sense of responsibility, so the better workers try harder to maintain good health. The other is that healthier people are simply better able to perform at a high level in the workplace, while for others illness may cause productivity to suffer.

There’s been relatively little research on the connection between work performance and health. One study by Brigham Young University’s department of health science found that employee engagement, health behavior, and physical health were significantly associated with job performance and absenteeism. The research was based on 20,000 employees of three U.S. companies who completed surveys between 2008 and 2010.

For each of the three performance groups in the HCMS study, researchers calculated the average annual medical costs and the average risk score, using the Human Capital Risk Index® (HUI, patent pending). The HUI score takes into account about 300 variables for each individual, including medical diagnoses, health plan costs, compensation policies, and use of disability and workers’ compensation benefits. The average risk is 1.0.

Risk Score Health Plan Cost by Performance Group

Medical costs for the entire group averaged $5,455 for the year. Those in the top-performing 20% had average health expenses of $4,100, more than a third lower than the middle group’s $5,600. People in the lowest performance band had healthcare costs 41% higher than those in the middle band.

Similarly, the HUI risk scores average 1.0 for the top-performing group, or 17% lower than for those in the middle group. The lower-rated band had average risk scores 17% higher than those in the middle. The research also found that those in the middle and lower performance groups were two to three times as likely to have a disability claim. Workers’ compensation filings were twice as high for the bottom group as for the upper two categories.
