        한국인 체질량지수와 식이섭취, 혈청지질 및 동맥경화 위험인자와의 연관성 오년간의 연구조사(1995~1999)

        김진옥,위효정 대한지역사회영양학회 2001 대한지역사회영양학회지 Vol.6 No.1

        This investigation studied the relationship between Body Mass Index(BMI) and dietary intake, levels of serum lipid, lipoprotein(a) and plasminogen activator inhibitor-1(PAI-1) of 28,449 Korean adults(16,937 men, 11,542 women) from 1995 to 1999. The dietary assessment was conducted using 24-hour dietary records and food frequency questionnaires. During this five year study, the BMI normal-weight group, as a percentage of the annual test population, decreased from 68.0% to 60.2%, while the BMI overweight and obese groups collectively increased from 25.0% to 29.7%. The levels of serum total cholesterol (TC), LDL-cholesterol(LDL-C), Triacylglycerol(TG) and PAI-1 increased as the values of BMI increased, while the levels of HDL-cholesterol(HDL-C) and lipoprotein(a)(men only) appeared to decrease as values of BMI increased. The levels of daily energy intake also increased as values of BMI increased in both men and women. The obese group had significantly higher levels of carbohydrate, protein, fat(men only), alcohol(men only), and cholesterol intake than those of the normal-weight, underweight, and overweight groups. In men, BMI positively correlated with the levels of macronutrients and cholesterol intake(p < 0.001), % energy of protein, fat, and alcohol intake(p < 0.001), and the levels of serum TC, LDL-C, TG and PAI-1(p < 0.001), while BMI negatively correlated with % energy of carbohydrate intake, and the levels of Lp(a) and HDL-C(p < 0.001). In women, BMI negatively correlated with the level of cholesterol(p < 0.01), fat(p < 0.001), alcohol intake(p < 0.05), % energy of fat (p < 0.001), % energy of alcohol intake and level of and HDL-C(p < 0.001). Subjects who had serum TC, LDL-C, HDL-C, and TG levels greater than the standard reference values(TC > 240 mg/dl, LDL-C > 130 mg/dl, HDL-C > 35, TG > 200 mg/dl)' exhibited a higher intake of the three macronutrients, iron, calcium, meat, milk and fatty foods than those subjects who had serum lipid concentrations less-than-or-equal-to the standard reference values. Overall, there was positive correlation between the high risk factors of vascular disease variables, dietary intake, and BMI. Prevalence of hypertension and high blood sugar were increased as BMI increased, but the prevalence of hypertension is decreased as the year goes by. These findings showed that dietary intake, level of serum lipids and other vascular disease risk factors increased as BMI increased. Therefore, middle or upper class Korean adults who have high BMI should improve their eating habits. This would involve reducing alcohol, animal fat, high carbohydrate foods, and overall food intake, and balancing daily dietary intake in order to lower vascular disease risk factors, including obesity.

      • The Relation of Body Mass Index to Dietary Intake and Blood Lipid Levels in Korean Adults

        Jean, Rim,Kim, Chin-Ock,Kang, Soon-Ah,Wee, Hio-Jung The Korean Nutrition Society 1998 Nutritional Sciences Vol.1 No.1

        This study was designed to investigate the relationship between body mass index (BMI) and dietary intake, and the relationship between BMI and plasma lipid levels in Korean adults. This study was conducted from January 1 to December 31 of 1997. It consisted of 3781 subjects (men 2402, women : 1379) with the majority between the ages of 40 and 59. The dietary assessment was based upon a twenty-four-hour food record. Subjects were classified into one of four reference BMI groups : underweight ($\leq 20 kg/m^2$), normal (20.1-25.0 kg/$m^2$), overweight (25.1-30.0 kg/$m^2$), and obese (>30 kg/$m^2$). The biochemical assessment included measurements of plasma total cholesterol (TC), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C), triglyceride (TG), lipoprotein (a), and plasminogen activator inhibitor-1 (PAI-1). The BMI study showed that 60.5% of the men measured were normal and 32.6% of the men were overweight and/or obese subjects. Sixty-four percent of the women were normal and 20.3% of the women measured were overweight and/o. obese subjects. With respect to the daily energy intake of the men and women subjects, the levels of daily energy intake appeared to increase as values of BMI increased. Men of the overweight group had significantly higher protein, fat and cholesterol intake than those of the normal or the underweight groups. The alcohol intake of the men in the overweight group was also significantly higher than that of the men in the underweight group. With respect to percent energy intake of macronutrients, there was no significant difference between the four BMI groups and percent energy intake for all the subjects in the study. The ratio of percent energy intake of carbohydrates : protein : fat : alcohol of the normal women group was 62 : 17 : 20 : 1, respectively. Women apparently had a higher intake of carbohydrates than men (52 : 17 : 19 : 10). With respect to the levels of plasma TC, LDL-C, TG, and HDL-C, the levels of plasma TC, LDL-C and TC appeared to increase as the values of BMI increased, while the level of HDL-C appeared to decrease as values of BMI increased. Levels of lipoprotein (a) appeared to be inversely related to the values of BMI, and levels of PAI-1 appeared to increase as values of BMI increased. The results of this study demonstrate that there is a relationship between dietary intake and BMI, and that there is a relationship between BMI and blood lipids levels.
