Low iron linked to pregnancy depression

Evidence suggests low iron levels are linked to depression in the general population, but there are no pregnancy studies.

Here, doctors reviewed the medical records of 142 women, aged 18 to 25, and beyond 20 weeks pregnant when tested for ferritin, a biomarker for iron stores. Women deficient in iron had depression scores 29 percent higher than those with good iron levels, and these women were two-and-a-half times more likely to develop depression while pregnant.

Doctors also compared other health factors including family history, lifestyle, physical activity, and socioeconomic status, and found that iron levels remained an independent factor in developing depression while pregnant.
