Maternal Uncontrolled Anxiety Disorders Are Associated With the Increased Risk of Hypertensive Disorders in Japanese Pregnant Women.
BACKGROUND
We examined the risk of hypertensive disorders in relation to maternal depressive and anxiety disorders which were diagnosed before or during early pregnancy in Japanese women.


METHODS
We reviewed the obstetric records of all Japanese singleton deliveries at ≥ 22 weeks' gestation managed at the Japanese Red Cross Katsushika Maternity Hospital between 2009 and 2014. Potential risk factors for hypertensive disorders with maternal depressive and anxiety disorders were selected as follows: maternal age, parity, medications, self-interruption of medications and economic problems.


RESULTS
The incidence of hypertensive disorders did not increase in the pregnant women with depressive disorders compared with that in the normal control pregnant women (P = 0.96). However, the incidence of hypertensive disorders in the women with anxiety disorders was higher than that in the control women (odds ratio (OR): 2.61, 95% confidence interval (CI): 1.4 - 5.0, P < 0.01). In the women with anxiety disorders, 19% performed self-interruption of medications during pregnancy, and it was associated with the increased risk of hypertensive disorders (vs. no medication group, OR: 7.50, 95% CI: 1.5 - 38, P = 0.03; vs. medication group, OR: 16.0, 95% CI: 2.4 - 110, P < 0.01).


CONCLUSIONS
Maternal uncontrolled anxiety disorders due to self-interruption of medications seemed to be associated with the increased risk of hypertensive disorders in Japanese pregnant women.
