Abstract

The purpose of this study was to compare the nutrient intakes, blood pressure, and blood lipids in Korean adults according to BMI. Subjects were recruited and divided into three groups according to BMI, which included normal group (18.5< or =BMI<23), overweight group (23< or =BMI<25), obese group (25< or =BMI). The average age, height, weight, BMI of the subjects were 53.1years, 159.2cm, 54.5kg, 21.4kg/m2 for normal group, 52.3years, 159.4cm, 61.4kg, 24.1kg/m2 for overweight group, 55.9years, 158.7cm, 68.5kg, 27.2kg/m2 for obese group, respectively. There were not significant differences in energy and food intakes by BMI groups. The blood pressure, serum cholesterol, serum triglyceride, serum LDL-cholesterol, and AI were significantly increased and serum HDL-cholesterol decreased with increment of BMI. The age and BMI were significantly positively correlated with blood pressure and serum lipids except HDL-cholesterol. There was significantly negative correlation between percentage of protein energy intake and AI. To summarize these results, energy, nutrient, and food intakes were not significantly correlated with BMI, and blood pressure and blood lipids increased with increment of BMI. Further systematic study of relation among nutrient intakes including various life factors, BMI, blood pressure, and blood lipid profile is needed.
