ABSTRACT
The purpose of this study was to determine the 2-year impact of a worksite-based diabetes prevention program. Thirty-seven pre-diabetic and previously undiagnosed diabetic employees participating in a 12-month worksite diabetes prevention program were included. Weight, body mass index, waist circumference, oral glucose tolerance testing, fasting insulin, blood lipids, and aerobic fitness had improved significantly after 6 months. Much of this improvement continued through 12 months. One year following the intervention, oral glucose tolerance and aerobic fitness had improved significantly. Of the 22 employees remaining in the study through 24 months, more than half had normal results on glucose tolerance testing. Worksite diabetes prevention programs may reduce blood glucose below pre-diabetic and diabetic levels. Improvements in diabetes risk factors persisted for at least 2 years in most of these employees.

The purpose of this study was to determine if the U.S. National Institutes of Health Diabetes Prevention Program (DPP) could be successfully implemented in a worksite setting. Thirty-seven adult employees of BD Medical Systems of Sandy, Utah were enrolled in a single-group time-series study using the DPP. Two-hour oral glucose tolerance tests (OGTT) and other outcomes were measured at baseline, 6 months, and 12 months. Weight, body mass index, waist circumference, 2-hour OGTT, very low density lipoproteins, triglycerides, and aerobic fitness were significantly improved at 6 and 12 months and showed overall significant improvement across time. Fasting blood insulin, total cholesterol, low density lipoproteins, and total cholesterol/high density lipoproteins ratio were significantly improved at 6 months, but not at 12 months. Eighteen of the program participants (51%) were no longer in the pre-diabetes and diabetes categories after 1 year. Existing worksite health promotion and occupational health professionals can successfully offer the DPP and help employees improve glucose tolerance.
