A Study of the Levels of Serum Lipid, Insulin and Plasma Ascorbic Acid in Obese College Men

The purpose of this study was to investigate the blood concentrations of lipids, insulin and ascorbic acid, and their correlations in obese college men in Gyeongnam area. The blood pressure was significantly higher (p<0.001) in the obese group($127.8{\pm}7.2/86.7{\pm}9.2\;mmHg$) than the control group($112.8{\pm}6.6/71.9{\pm}6.6\;mmHg$). The serum triglyceride (p<0.01), total cholesterol (p<0.01), LDL-cholesterol (p<0.05), insulin (p<0.001) concentrations and atherogenic index (AI) (p<0.001) were significantly higher in the obese group ($158.8{\pm}79.7\;{\mu}U/L$, $185.0{\pm}26.8\;{\mu}U/L$, $111.9{\pm}28.1\;{\mu}U/L$, $15.2{\pm}5.6\;{\mu}U/L$, $3.6{\pm}1.0$) than the control group($111.9{\pm}35.8\;{\mu}U/L$, $165.9{\pm}19.4\;{\mu}U/L$, $97.0{\pm}16.4\;{\mu}U/L$, $8.9{\pm}4.4\;{\mu}U/L$, $2.6{\pm}0.3$), but HDL-cholesterol concentration was significantly higher (p<0.01) in the control group($46.5{\pm}7.2\;{\mu}U/L$) than the obese group($41.3{\pm}6.9\;{\mu}U/L$). On the other hand, there was no significant difference in the plasma ascorbic acid concentration in both groups. The ascorbic acid concentration was negatively correlated with total cholesterol level in the control group, and with triglyceride, total cholesterol levels and diastolic blood pressure in the obese group (p<0.05). These data show that young adult obesity might be related to hyperlipidemia, atherosclerosis, hypertension and diabetes mellitus, and that the nutrition of ascorbic acid is more important for obese males than normal weight males.
