Deficiencies of trace elements is an important public health problem that threatens mainly pregnant women and their products; we propose to determine serum iron (Fe), Zinc (Zn) and copper (Cu) during the first trimester of pregnancy and identify the pathologies associated with a deficiency during the first trimester of pregnancy in pregnant women attending antenatal care at Maternity Dr. Armando Castillo Plaza, University Hospital of Maracaibo, Venezuela during 2012. A descriptive and applied type research, with a non-experimental and prospective design, which includes a non-probabilistic intentional sample of 70 women during the first trimester of pregnancy, which were measured in serum Fe, Zn and Cu. We found that the age mean was 20,5± 6 years; in terms of the concentrations of these trace elements was determined an average of Fe, Zn and Cu of 40,04 ± 1,212 μg/dL, 0,566 ± 0,130 μg/mL and 1,326 ± 0,878μg/mL, respectively; with concentrations of Fe and Zn lower in adolescents (<0,001). It also showed that 67%, 57% and 14% of these pregnant women were deficient in Fe, Zn and Cu, respectively; without not significant differences between adolescents and adults patients (p> 0,05). Its concluded that exist a high prevalence of deficiencies of trace elements (Zn, Cu and Fe) in patients without associated diseases and apparently healthy at the beginning of her pregnancy.
