20세 이상 남녀의 일상 식이중 이소플라본 섭취와 혈압, 혈중 지질과의 관련성 = A study on relation among habitual isoflavone intake, blood pressure, and serum lipid parameters in Korean men and women over 20 years old

다국어 초록 (Multilingual Abstract)

There is some evidence that soy isoflavone has beneficial effects on the concentration of blod lipids. In this study, we investigated habitual isoflavone intake levels and the relation among dietary isoflavone intake, blood pressure, and blood lipids of adult men (n = 149) and women (n = 205). Anthropometric measurements including blood pressure, dietary in-take assessment using 24-hour recall method, and biochemical assessment using blod were conducted. The average age, height, weight, and BMI were 54.7 years, 168.5 cm, 67.3 kg, and 24.5 kg/m2 for men and 53.9 years, 153.8 cm, 59.2 kg, and 25.0 kg/m2 for women, respectively. The mean daily intakes of total food and energy were 1219.1 g and 1740.9 kcal (daidzein + genistein) intake of men and women were 20.0 mg and 14.2 mg, respectively. Blood pressure of the subjects was 128.3/75.5 mmHg for men and 124.1/73.7 mmHg for women. Serum lipids of men and women were 180.2 and 184.9 mg/dL for total cholesterol, 160.8 and 137.6 mg/dL for triglyceride, 41.5 and 44.7 mg/dL for HDL-cholesterol, 106.6 and 112.7 mg/dL for LDL-cholesterol, and 3.5 and 3.3 for atherogenic index, respectively. Serum triglyceride and atherogenic index of men were significantly higher than those of women. In men, isoflavone intake and the level of total serum cholesterol were nega-(p < 0.05) correlated, after adjusted age. In women, there were significant corelations between isoflavone intake and blood pressure (systolic and diastolic), after adjusted age (p < 0.05). Based on these results, we concluded that higher isoflavone intake seemed to be related to a beter lipid profile in men and lower blod pressure in women. But more epidemiological studies and controled clinical trials would help to confirm the optimal amount required for the preven-(Korean J Community Nutrition 10(4) : 493 ~ 500, 2005)
