A Study on the Serum Lipid, Apolipoprotein Levels and Their Correlations in Healthy Adults of Gyeongnam Area

ABSTRACT

The purpose of this study was investigating serum lipid, apolipoprotein levels and their correlations in healthy adults of Gyeongnam area. The BMI (body mass index) was significantly higher (p < 0.001) in male (25.2 +/- 2.7 kg/m2) than female (23.8 +/- 1.5 kg/m2), however PBF (percent body fat) was significantly higher (p < 0.001) in female (29.6 +/- 4.3%) than male (22.7 +/- 5.0%). The WHR (waist to hip ratio) and blood pressure in the groups showed there was no significant differences. The levels of serum total cholesterol, LDL-cholesterol and apolipoprotein B were significantly higher (p < 0.01) in male (208.7 +/- 27.7 mg/dl, 129.0 +/- 26.9 mg/dl, 1.0 +/- 0.2 g/L) than female (193.6 +/- 29.1 mg/dl, 112.5 +/- 29.5 mg/dl, 0.9 +/- 0.2 g/L, but HDL-cholesterol level was significantly higher (p < 0.01) in female (54.9 +/- 6.6 mg/dl) than male (49.9 +/- 7.3 mg/dl). The LDL-C/HDL-C, Apo B/Apo A-I and AI (atherogenic index) were significantly higher (p < 0.001) in male (2.6 +/- 0.6, 0.8 +/- 0.2, 3.3 +/- 0.7) than female (2.1 +/- 0.5, 0.6 +/- 0.2, 2.6 +/- 0.5). The triglyceride level was positively correlated with apolipoprotein B concentration (p < 0.05) and negatively correlated with HDL-cholesterol concentration (p < 0.05), however no significant correlation was found with apolipoprotein A-I. According to these results, we conclude that male adults are expecting higher incidence of cardiovascular disease than female adults and we suggest the serum triglyceride should be kept normal level for the prevention of these diseases.
