SUMMARY
Obesity is one of the risk factors of cardiovascular disease. The prevalence of obesity in Indonesia has increased in the last few years, therefore some efforts to reduce the risk is needed. In the current study, efforts are given through 3-week lifestyle modification education, with 3-month total of follow-up (from March to June 2014) and then the impacts on cardiovascular risk profile were observed and seen on 24 sedentary male workers in University of Surabaya with obese II. This study used before-after study design in order to see the impacts of the 3-week lifestyle modification education towards change of knowledge, dietary behavior, body mass index (BMI), waist circumference, and cardiovascular risk profile through various educational methods (face-to-face session, given recorder of face-to-face session, and combination of both methods). Statistical analysis was performed using Wilcoxon signed test. Result showed an increasing knowledge in face-to-face group (p=0.046). However, there were no significant changes in other variables (dietary behavior based on healthy diet indicator (HDI), BMI, waist circumference, and also cardiovascular risk profile) in all groups between before and after education intervention (p>0.05). In conclusion, lifestyle modification education given for 3 weeks did not reduce the cardiovascular risk profile on sedentary male workers with obese II. Longer term intervention and multicomponent program including behavior therapy may be needed to succeed lifestyle changes and reduce cardiovascular risk.
