All participants gave informed consent for research. The ferritin concentration in their preserved serum was measured. The hemoglobin (Hb) and ferritin in early pregnancy, as well as the Edinburgh Postpartum Depression Scale (EPDS) at mid\u2010pregnancy and 1\u2009month after childbirth were analyzed.
