Resumen

ACOSTA GARCIA, Edgar et al. Zinc and copper in serum and zinc/copper ratio in a group of children from South Valencia, Venezuela. Acta bioquím. clín. latinoam. [online]. 2010, vol.44, n.1, pp. 295-297. ISSN 0325-2957.

Sera levels of zinc (Zn), copper (Cu) and the ratlo zlnc/copper (Zn/Cu) were analyzed In 82 apparently healthy chlloren between 4 and 14 years of age from Valencia Clty Venezuela. The Zn (μg/dL) and Cu (μg/dL) were determlned by fíame atomic absorption spectrometry and the nutritional state was evaluated wlth Welght/Helght, Helght/Age and Body Mass index. Zn, Cu and the Zn/Cu were (Deflned by average±standard devlatlon): (84.2±15.9), (125.4 ± 24.8) and (0.69±0.18) respectlvely There was no significant diffference by gender. There was inverse and significant correlation between Cu and age. Zn deficiencies were 15.9%, and they were hígher in girls (18.6%) than in boys (13.2%). Children =11 years of age had 22.2% Zn deficiencies. There were no Cu deficiencies. No significant association was found between Zn, Cu, Zn/Cu and the nutrítíonai state. Zn, Cu ana Zn/Cu were different from those found in other investigations and hipozincemia in children affected mostiy femaies and those of oider age.
