The present study was aimed at investigating whether there are sex-related differences in serum levels of lipids, retinol , $alpha$-tocopherol and ascorbic acid in Korean adults. Serum levels of antioxidant vitamins and lipids were determined algon with anthropometric measurements in 53 healthy male subjects with mean age 42.7$pm$12.2 years and 44 female subjects with mean age 46.7$pm$10.3 years. from Taegu in Korea. BMI and W/H ration of the men were 22.66$pm$2.47, 0.88$pm$0.04 and those fo thewomen were 23.36$pm$3.44, 0.84$pm$0.05 respectively. Systolic and diastolic blood pressures were 121.67$pm$14.8, 79.3$pm$12.4 in the men and 123.1 $pm$17.5 , 78.8$pm$10.9 in the women respectively. Average serum levels of total cholesterol, LDL-and HDL-cholesterol and triglyceride were 165.8$pm$36.4, 102.6$pm$31.2, 41.1$pm$10.5 and 110.2$pm$57.8mg/dl in the and 169.1$pm$39.1, 113.7$pm$36.2, 38.1 $pm$8.6, and 85.2$pm$37.7mg/dl in the women respectively. Thirteen percent of menans thirtyeight percent of women had LDL-cholesterol over 130mg/dl. Serum levels of retinol, $alpha$tocopherol, ad ascorbic acid were 43.25 $pm$15.51, 17.93$pm$7.07, 115.24$pm$63.25ug/dl in the men and 31.80$pm$15.39, 17.41$pm$6.12, an d144.99$pm$89.87ug/dl in the women respectively. Serum vitamin E showed positive correlations with total cholesterol and LDL-cholesterol and triglyceride.
