This study was undertaken to investigate the relationship between the life style and the nutritional status of serum antioxidant vitamins and lipids in university male and female students. 48 male and 49 female students attending Andong university, aged between 18 and 25 years, were selected. Questions about the life styles including dietary intakes, food habits, smoking, drinking alcohol, exercise, stress were answered. And serum levels of antioxidant vitamins and lipids were determined. Average serum levels of total cholesterol, LDL C, HDL C, and triglyceride in male and female subjects were 158.6$pm$32.7, 177.3$pm$33.8; 86.4$pm$26.0, 109.0$pm$31.2; 46.0$pm$10.7, 49.9$pm$12.4; 131.2$pm$22.5, 91.7$pm$ 38.6mg/dl respectively. Average serum levels of antioxidant vitamin A, E and C in male and female subjects were 42.6$pm$12.3, 31.4$pm$9.8 g/dl, 1.11$pm$0.38, 1.15$pm$0.29mg/dl and 164.66 $pm$65.01, 220.06$pm$80.11 g/dl respectively. There was no significant difference between smoking habits and either serum lipids or antioxidant vitamins level. The serum vitamin C level of drinkers was significantly lower(p=0.038), but serum lipids(total cholesterol, LDL C, and triglyceride) were higher than non alcoholic subjects. The subjects with severe stress had lower in HDL C and higher in atherogenic index than others. This result indicates that oxidative stress may be increased in stressful environment from undesirable life styles and influence the status of serum lipid and antioxidant vitamins.
