Adherence

A multicomponent workplace wellness program (nutrition, physical activity, stress reduction) significantly increases self-reported healthy behaviors (exercise, weight management) but has no significant effect on clinical health markers, healthcare spending, or employment outcomes after 18 months.

If you are an employer considering a wellness program, expect it to boost employee engagement and self-reported healthy habits (like exercising more), but do not expect it to lower your healthcare bills or improve clinical health metrics (like weight or blood pressure) within 18 months. The program's value lies in behavioral nudges, not immediate clinical or financial ROI.

the program had no significant effects on other prespecified outcomes: 27 self-reported health outcomes and behaviors... 10 clinical markers of health... 38 medical and pharmaceutical spending and utilization measures, and 3 employment outcomes... After 18 months, the rates for 2 self-reported outcomes were higher in the intervention group than in the control group: for engaging in regular exercise... and for actively managing weight
