In 153 randomly selected children with no clinical and laboratory findings of acute infection, the mean (± SEM) fasting plasma zinc, iron and copper levels (0.699± 0.028 mg/L, 1.553+ 0.083 mg/L and 1.012+0.039 mg/L, respectively) were pair-assessed on an atomic absorption spectrophotometer. A significant simple linear relation was found between plasma zinc (PIZn) and iron (PIFe) levels and the regression equation was plasma (PIZn)=0.602+0.062(PIFe), p<0.022, r=0.184. However, the polynomial parabolic relation between zinc and iron was not found significant. Whereas, a significant polynomial parabolic relation was found between plasma zinc and copper (PICu) and the regression equation was (PIZn)=0.411+0.471 (PICu)-0.154(PICu) 2 p<0.024, r=0.220. In addition, a significant multiple relation with a constant was found between plasma zinc, copper and iron levels and the regression equation was PIZn=0.476+0.121(PICu)+0.158(PIFe) p<0.008, r=0.249. and without a constant the regression equation was PIZn- -0.160(PICu)+0.184(PIFe). In conclusion, in children at steady state, when plasma zinc level was high the plasma iron level was also found high; whereas, plasma copper level was found low.
