Objective This study examined how the implementations of session goal contribute to subject's outcomes after a lifestyle intervention program for 12 weeks in males with metabolic syndrome (MetS). Methods The intervention study on 30 male workers aged 36~58 years (mean aged: 47.2±6.6) with MetS were participated in this study from March to June, 2011. The intervention program conducted 5 face-to-face counseling during the 12 weeks program. The subjects were divided into three groups according to their implementation of session goal levels: Low-Implementation group (LI, 70%). Anthropometric parameters, biochemical parameters and nutrient intakes were examined at baseline and at the end of the 12 weeks intervention program. Results After 12 weeks intervention program, diastolic blood pressure (DBP), waist, intakes of energy, fat and sodium and the number of components of MetS were significantly decreased (P＜0.05). According to implementation goal levels, HDL, LDL, percent of body fat, systolic blood pressure (SBP) and DBP were significantly decreased in the HI group (P ＜0.05). In LI group, total cholesterol (TC) was significantly increased, however DBP and intakes of protein and sodium were significantly decreased (P＜0.05). Especially, the HI group had a greater levels of changes in TC, HDL, LDL, SBP, DBP and intakes of fiber compared to the LI and MI group (P＜0.05). The number of components of MetS were significantly decreased in HI group (P＜0.05), but the change levels were not significantly different among three groups. Conclusion The lifestyle intervention program is effective in decrease risk of MetS, especially in the high implementation group. Therefore, we suggest that it is necessary to set up a suitable disease session goals at application of protocol and a systematic strategy for increasing implementation level.
