BACKGROUND/OBJECTIVES: The purpose of this study was to investigate the overall effects of a tailored Dietary Approachesto Stop Hypertension (DASH) nutritional intervention program which included omega-3 fatty acids supplementation, on dietaryself-efficacy, dietary knowledge, and dietary behaviors in Korean elderly women with abdominal obesity. Furthermore, we investigatedthe effects of the program on metabolic syndrome parameters including the antioxidant capacities in these subjects. SUBJECTS/METHODS: A randomized, controlled trial was conducted for 8 weeks. The experimental group (n = 21) receiveda weekly tailored nutritional program for 8 weeks and the control group (n = 18) received only one educational session. Theclinical survey was conducted before and after the intervention period. RESULTS: After the intervention, dietary self-efficacy (P = 0.023), frequency of fruit intake (P = 0.019), and dietary fiber intake(P = 0.044) were higher in the experimental group than in the control group. The oxidative stress (P < 0.001) was lower inthe experimental group than in the control group. Moreover, low density lipoprotein (LDL) cholesterol (P = 0.023) had significantlydecreased in the experimental group but not in the control group after the intervention. CONCLUSIONS: The intervention program including omega-3 fatty acid supplementation had a positive effect on dietary self-efficacy,dietary behaviors, and oxidative stress among aged women with abdominal obesity.
