This study was conducted to clarify the relationship of body fat percent with serum lipid level and blood pressure in adults. The study subjects were 472 men and 189 women who visited Multiphasic Health Screening Center of Yeungnam University Hospital in Taegu from May 20 to September 30, 1994. The relationship of serum lipid and blood pressure with BMI, Katsura index, atherogenic index, which calculated from the health screening data and body fat percent measured by impedance fat meter(model SIF-819) were analyzed.
Three groups were classified as Group I (men : body fat percent > 20, women : body fat percent >_ 25), Group II (men : 15 < body fat percent< 20, women : 20 <_ body fat percent< 25), Group III (men : body fat percent < 15, women : body fat percent < 20). In this study, Group accounted for 3.2% in men, 3.7% in women.
Weight was significantly different among three groups in both sexes(p <0.01) and height was not significantly different among three groups. In men, serum total cholesterol, triglyceride, high density lipoprotein, low density lipoprotein, atherogenic index were significantly different(p <0. 01). In women, serum total cholesterol and low density lipoprotein were significantly different(p <0.05) but there was no differences in triglyceride and high density lipoprotein among three groups. BMI and Katsura index were significantly different among three groups in both sexes(p <0.01).
In men, body fat percent was positively correlated with weight, BMI, Katsura index, total cholesterol, triglyceride, low density lipoprotein, atherogenie index and systolic and diastolic blood pressures, and negatively correlated with high density lipoprotein. In women percent was positively correlated with age, height, , body fat weight, BMI, Katsura index, total cholesterol triglyceride, low density lipoprotein and atherogenic index, and negatively correlated with high density lipoprotein. But there was no significant correlation between body fat percent and blood pressure in women.
In multiple regression analysis for total cholesterol, fat percent, age and BMI were significant independent variables in men(p <0.05, 86), and body fat percent and age in women(p <0. R´=0.12 05, R´=0.3399). In case of LDL/HDL ratio, only BMI was a significant independent variable in men(p <0.01 R´=0.0954), and body fat percent, age and BMI in women (p
In multiple regression analysis, , age, low density lipoprotein and total cholesterol were significant independent variables on systolic blood pressure in men and total cholesterol in women (P X0.05, R´=0.1297), age (p <0.05, R´=0.1705). On diastolic blood pressure, only age was a significantly independent variable in men(p<0.01, R_=0.0972) and women(p <0.01, Rz=0.1218).
From the result of this study, it could concluded that body fat percent was significantly associated with other obesity indices and serum lipid, but had no significant association with blood pressure. To establish the relationship of body fat percent with blood pressure, further study which consider other variables that may have an effect on blood pressure should be performed.
