EFFECTS OF ۵-YEAR INTERVENTIONS ON CARDIOVASCULAR RISK FACTORS OF FACTORIES AND OFFIES EMPLOYEES OF ISFAHAN AND NAJAFABAD: WORKSITE INTERVENTION PROJECT-ISFAHAN HEALTHY HEART PROGRAM

Abstract BACKGROUND: Effects of ۵-year interventions of Worksite Intervention Project from Isfahan Healthy Heart Program on cardiovascular risk factors of factories and offices employees were studied in Isfahan and Najafabad (intervention area) compared to Arak (control area). METHODS: We had especial interventions for nutrition, physical activity and smoking as well as hypertension and obesity screening systems in all offices and factories, and other risk factors screening systems whenever possible. Before and after the interventions, questionnaires containing demographic and other required data were completed for the two populations; height, weight and blood pressure (BP) were measured and a fasting and ۲h blood sample was taken for the measurement of blood sugar (BS) and lipid levels.. RESULTS: The prevalence of Hypercholesterolemia, hypertriglyceridemia and central obesity decreased, but low HDL increased in office staff (P < ۰.۰۱). Waist circumference, HDL and total cholesterol mean values decreased, and diastolic BP and fasting and ۲h BS increased among the intervention group. In factory workers, the prevalence of  hypertriglyceridemia and central obesity decreased, while low HDL prevalence  increased in intervention group (P < ۰.۰۰۱). Mean values of waist circumference, HDL, total cholesterol, and triglyceride decreased significantly (P < ۰.۰۰۱), while diastolic BP and fasting BS increased. CONCLUSION: It seems that Worksite Intervention Project has a protective effect on CVD risk factors in factories and offices employees. So, the modifiable project can be used as an applicable tool for health improvement in worksites which creates tangible changes in employees’ lifestyle.   Key words: Risk Factors, Cardiovascular Disease, Workplace, Intervention
