Evaluating the effects of copper supplement during pregnancy on premature rupture of membranes and pregnancy outcome

Abstract

Objective: To evaluate the effects of copper (Cu) supplementation during pregnancy on the rupture of membranes and pregnancy outcomes.

Methods: Study was conducted as a triple-blind randomized clinical trial. In one group, Cu in a dose of 1000 mg per day, and in the other group, placebo was prescribed orally from 16th week of pregnancy.

Results: The women of the two groups did not have significant difference according to age, gestational age at recruitment, BMI, and socioeconomic conditions. There was no statistically significant difference between case and control group regarding the incidence of PPROM, PROM, preterm labor, vaginal bleeding during pregnancy, preeclampsia, and the incidence of placenta abruption. There was a 75% and 90% decrease in depressive symptoms in 2nd trimester and 3rd trimester in supplemented group, respectively. Also, there was a 45% and 80% decrease in anxiety symptoms in 2nd trimester and 3rd trimester in the supplemented group, respectively The rate of infection during pregnancy was significantly higher in control group (p = 0.046). There was no difference between the two groups according to neonatal outcomes.

Conclusions: Cu supplementation during pregnancy could not influence positively on ROM; however, it could improve some mood status of the women.
