Impact of anemia on the six-month trend of anxiety and depression in women with threatened abortion: A case-control retrospective cohort study.

BACKGROUND

Anemia in pregnancy is associated with psychiatric symptoms and poor psychiatric symptoms, this study investigates the 6-month trends of anxiety and birth outcomes. Considering the controversies surrounding the impact of anemia on psychiatric symptoms, this study investigates the 6-month trends of anxiety and depression in anemic pregnant women with threatened abortion (TA).

METHODS

A case-control retrospective cohort study conducted among 282 participants who enrolled in a registry of pregnant women with TA in Babol city from December 2022 to October 2023. Fifty individuals with anemia (hemoglobin < 11 g/dL) who were matched with 50 without anemia based on age, pregnancies, education, and gestational age, were included. The BSI-18 (Brief Symptom Inventory) was used to assess depression, anxiety, and psychological distress at the beginning, three and six-month follow-ups.

RESULTS

The prevalence of anemia among women diagnosed with TA was found to be 17.7%. At the beginning, compared to normal individuals, anemic women had higher rates of depression (32% vs. 14%), anxiety (34% vs. 22%), and psychological distress (66% vs. 48%). Moreover, at 3- and 6-month follow-ups, the frequency of psychiatric symptoms in anemic women was significantly higher. The Generalized Estimating Equations model showed that although both groups had a decreasing trend of frequency anemic women experience a slower rate of decrease in psychiatric symptoms compared to non-anemic women.

CONCLUSION

Anemia in women with TA is associated with high rates of depression, anxiety, and psychological distress, as well as a slow recovery rate.
