Abstract

BACKGROUND
The aim of this study was to examine the metabolic risk factors in the elderly. Exercise, energy intake, and patterns of antioxidant nutrient intake were investigated in obese subjects further classified into either with or without metabolic syndrome.
METHODS
This study analyzed 1,074 korean seniors who were over 65 years of age according to Korean National Health and Nutrition Examination Survey (KNHNES) 2010 using SPSS 19.0.
RESULTS
The subjects were classified into non-obese without MS, non-obese with MS, obese without MS, and obese with MS groups based on BMI (obese > or = 25 kg/m2) and MS components (> or = 3 criteria among 5 indices: waist circumference, triglyceride, glucose, HDL-cholesterol and blood pressure). Systolic pressure, diastolic pressure, fasting plasma glucose, HDL cholesterol, TG, and total cholesterol showed significant difference among the 4 groups (P<0.05). All the groups with metabolic syndrome showed high blood pressure, fasting glucose, and TG while HDL level was low. The ratio of carbohydrate intake, compared to the daily nutritional allowance, was significantly high while the proportion of fat intake was low in all 4 groups. Among the antioxidant nutrients, vitamin C consumption was lower than the recommended daily nutritional allowance while higher intake of fat soluble vitamin (retinol, carotene, and vitamin A) was noted among the obese group compared with the normal weight group. In addition, all groups showed low physical activity.
CONCLUSION
In this study, there were no significant differences between exercise and nutrient intake of antioxidant nutrients in the four groups of subjects. However, it is required to understand that antioxidant nutrient intake and exercise are necessary in the elderly population, because the body composition changes due to aging and metabolic syndrome.
