Direct and indirect annual health care costs for diabetes are $13,700 for a worker with diabetes compared to $5,800 for a healthy worker. A 5-year study of 617 foundry workers found that health coaching and monetary incentives led to improved health metrics like HbA1c, blood pressure, and lipids despite higher BMI and waist size. The intervention helped prevent the expected rise in HbA1c levels over 5 years and reduced the number of new diabetes cases, showing that lifestyle coaching can help curb diabetes development and benefit employers through cost savings and productivity gains.
