In twin pregnancies, zinc and iron decreased, while copper increased minimally

Objectives: Along with the increase in the frequency of multiple pregnancies, an increase is observed in the frequency of feto-maternal negativities. In our study, we aimed to determine the iron, ferritin, hemoglobin, zinc, and copper levels in second-trimester multiparous twin pregnancies and compare them with the values in singleton pregnancies and healthy women with the same demographic characteristics. Methods: Three groups were created in the study; control group, single pregnancy group, and twin pregnancy group. Fasting venous blood samples were taken from individuals. Iron, zinc, copper, and ferritin levels were measured. Results: Compared with the control group, the Fe, Ferritin, and Zn values of the individuals in the single and twin pregnancy groups were statistically low while Cu levels were significantly high (p
