Abstract

BORJA-MAGNO, Angélica; MUJICA-COOPMAN, María Fernanda; PIZARRO A, Fernando  and  OLIVARES G, Manuel. Iron, copper and zinc status in relation with the hormonal contraceptive method. Rev. chil. nutr. [online]. 2014, vol.41, n.3, pp.297-303. ISSN 0717-7518.  http://dx.doi.org/10.4067/S0717-75182014000300011.

Childbearing age women are part of a vulnerable group to present micronutrient deficiencies. It has been associated the contraceptive method (CM) with iron (Fe) status, and the hormonal CM (HCM) with the alteration of copper (Cu) and zinc (Zn) biomarkers. The aim of this study was to assess the effect of CM over the biomarkers of Fe, Cu and Zn status, and the prevalence of micronutrient deficiency on 81 Chilean childbearing age women. We evaluated mean corpuscular volume (MCV), hemoglobin (Hb), zinc protoporphyrin (Zpp), serum Fe (FeS) , transferrin saturation (TS), total Fe binding capacity (TIBC), transferrin receptor (Tfr), serum ferritin (SF), serum copper (CuS), ceruloplasmin (Cp) mass, activity and specific activity and serum zinc (ZnS). From the total women, 40% used HCM and 49% did not use HCM. Women using HCM showed higher values of FeS, ST, CuS, Cp mass and activity (p<0.05) and lower Zpp (p<0.05) compared with those that did not use HCM. Not statistical differences were found on MCV, Hb, TIBC, Tfr, SF, ZnS and Cp specific activity values between groups. HCM utilization did not affect Fe, Cu and Zn status in the studied population.

Keywords : Iron; copper; zinc; contraceptive method; childbea-ring age women.
