Scientists at the University of Granada say a low blood plasma level of copper and zinc in pregnant women may be a factor associated with spontaneous abortion.
The study involved 265 pregnant women who underwent an ultrasound examination, provided blood samples and completed questionnaires. In total, 131 variables were assessed from each participant.
During the one year study period, 132 women suffered a spontaneous miscarriage. The data obtained from the group of women who had suffered miscarriages was compared with those obtained from the group of women with a normal pregnancy. The results showed differences in maternal plasma concentrations of copper and zinc.
This finding suggests that maternal deficiency of one or both trace elements may be associated with the occurrence of spontaneous abortion, which opens new and lines of research in this area.
"Despite the significant progress made in reproductive medicine, spontaneous abortion is still the most frequent complication during pregnancy. It is estimated to affect 15 percent of pregnant women, mainly during the first trimester," noted University of Granada pharmacologist and study author Jesús Joaquín Hijona Elósegui.
