The effects of a 3‐year worksite health promotion program in male workers with metabolic syndrome

Abstract

The study aimed to examine the long‐term (3‐year) effects of lifestyle intervention on cardiovascular risk factors and dietary intakes in Korean male workers with metabolic syndrome (MS). We conducted a lifestyle intervention trial designed to modify personal lifestyles among 75 male workers (control group, n =45; intervention group, n = 30). The intervention consisted of two phases; a 12‐week main program (face‐to‐face counseling 5 times) and a 30‐week follow‐up program. Assessments included anthropometrics, body composition, biochemical parameters, and nutrient intakes. After the intervention, triglyceride (TG) was significantly reduced in the intervention group (baseline 275.47 ± 172.10mg/dL vs. after 3 years 202.23 ± 123.05mg/dL, p<0.05). HDL‐cholesterol (HDL‐C) significantly increased in both groups (p<0.05). There was no significant difference in nutrient intakes between at baseline and after 3 years. Compared with the control group, prevalence of MS and its risk factors (especially in High TG and low HDL‐C) were significantly reduced after 3 years in the intervention group (p<0.05). Continuous worksite‐based lifestyle intervention showed positive effects on MS prevalence and its components.
