The purpose of this study was to assess the zinc and copper nutritional status of 102 college women by measuring zinc and copper intake, hematological parameters of zinc and copper, hair zinc and urinary excretion of zinc and copper. The mean zinc intake was 5.5mg(45.8% RDA) with food analysis and 4.5mg(37.8% RDA) with computation from food composition table. The copper intake with food analysis was 2.3mg and 1.2mg with computation. Mean serum zinc concentration was 77.02ug/dl and the proportion of subjects with zinc deficiency estimated by serum zinc(<70ug/dl)was 23.0%. Mean serum copper concentration was 121.80ug/dl and 4.1% of subjects showed serum copper less than 70ug/dl, The mean ceruloplasmin concentration was 22.63mg/dl and the proportion of subjects whose ceruloplasmin was lower than 18-40mg/dl was 6.6%. The mean hair zinc of subjects was 143.8ppm and the mean hair copper was 11.2ppm. The mean urinary excretion of zinc was 0.43mg/day and the proportion of subjects with marginal deficiency estimated by urinary zinc excretion( <0.3mg/day) was 23.3%. The mean urinary copper excretion was 0.044mg/day which was within the normal range(0.01-0.06mg/day). Assessing by zinc content in hair, urine and serum, 22.9-23.3% of college women had bordeline zinc deficiency or zinc deficiency. Whereas 4.1-6.6% of college women was assessed copper deficiency estimated by serum copper and ceruloplasmin.
