Impact of a three-year worksite wellness program on employee blood lipid levels

Abstract

Worksite wellness programs can be used to implement interventions aimed at addressing current rates of obesity and related chronic disease and their associated health care costs. The purpose of this study was to evaluate the impact of a worksite wellness program on blood lipid levels among employees at a rural manufacturing plant in Northern California. Pre to post changes were analyzed using paired sample ttests. Demographic data collected as part of a subsequent nutrition education component of the program indicated that the employees were mostly male (88%) and Caucasian (71%), with a mean age of 47 ± 9 years. Forty-seven percent of the subjects were overweight and 38% obese. Following the three-year worksite wellness program, subjects’ total cholesterol, LDL-cholesterol, and triglyceride levels decreased, while their HDL-cholesterol levels increased significantly. These results suggest that long-term worksite wellness programs can improve employee health outcomes.
