Economic problems and mental disorders in Japanese pregnant women

Relationship between postpartum depression and lactation status at a Japanese perinatal center: A cross-sectional study

Background:  Some studies have demonstrated that breastfeeding can protect mothers from postpartum depression; therefore, we examined the association between postpartum depression and lactation status at one month after delivery at a Japanese perinatal center.

Methods: We reviewed the obstetric records of all (total 809) nulliparous healthy women with vaginal singleton delivery at 37-41 weeks’ gestation at our institute between July 2018 and June 2019. A face-to-face interview with the women was conducted on admission for delivery to ask whether or not they hoped to perform exclusive breastfeeding for their babies, and an additional interview was conducted one month after delivery to ask about their feeding methods currently. Maternal mental status was examined based on the scores using the Edinburgh Postnatal Depression Scale (EPDS), and women with EPDS scores of ≥9 points were regarded as ‘positive screening’.

Results: 592 women (73.1%) hoped to perform exclusive breastfeeding for their babies on admission. Of these, at one month, 442 (74.7%) performed exclusive breastfeeding, while 150 (25.3%) performed mixed or artificial feeding. The average EPDS scores and the incidence of EPDS scores ≥9 points in the women performing exclusive breastfeeding were 4.3 ± 3.6 and 14.3% (63/442), respectively. They did not differ from those in the women performing mixed or artificial breast feeding [4.2 ± 3.7, p = 0.60 and 13.3% (20/150), p = 0.78].

Conclusion: Development of postpartum depression does not seem to be associated with incomplete breastfeeding at our hospital, and therefore there are other risk factors indicated in the development of postpartum depression.

Clinical significance of pregnancy in adolescence in Japan

OBJECTIVE

We examined the clinical characteristics and obstetric outcomes in adolescent pregnancies in Japanese women.

METHODS

The present study was a retrospective investigation of all primiparous Japanese women with singleton pregnancies who gave birth at ≥22 weeks' gestation aged ≤18 years old (adolescent pregnancy, n = 325) and aged 28-30 years old (n = 2029) at Japanese Red Cross, Katsushika Maternity Hospital between 2002 and 2016.

RESULTS

The frequencies of smoking, economic problems, an unmarried single status at delivery and the start of prenatal care in the first trimester in the adolescent pregnancy group were significantly higher than in the control group (p < .01). The incidences of Chlamydia trachomatis, Condyloma acuminatum, and mental disorders in the adolescent pregnancy group were significantly higher than in the control group (p < .01). Pregnancy in adolescence was not related to adverse obstetric outcomes except preterm delivery (p = .02).

CONCLUSIONS

Adolescent pregnancy was not associated with adverse obstetric outcomes; however, adequate social, economic, and mental support is needed for adolescent pregnant women.

Deterioration/relapse of depression during pregnancy in Japanese women associated with interruption of antidepressant medications

This study examined the risk of deterioration/relapse in pregnant women who discontinued their antidepressant medications based on the discretion of the psychiatric specialists compared with those who performed self-interruption. We reviewed the obstetric records of all singleton deliveries beyond 22 weeks of gestation at Japanese Red Cross Katsushika Maternity Hospital from January 2009 through December 2015. Compared with the women continuing antidepressant medications throughout pregnancy, the incidence of deterioration/relapse was higher in the women who discontinued their antidepressant medications regardless of who made the decision (interruption based on the discretion of the psychiatric specialists: 61%, odds ratio (OR), 8.05; 95% confidence interval (CI), 2.4-27; p < 0.01; self-interruption: 63%, odds ratio (OR), 8.79; 95% confidence interval (CI), 2.6-29; p < 0.01 versus 16%). The continuation of medications and careful observation are required for pregnant women complicated by depressive disorders.

Current Proportion of Women Receiving Perinatal Psychosocial or Psychological Intervention in Japan

Background

In this study, we examined the current status of psychosocial or psychological intervention for women during pregnancy and the postpartum period in Japan.

Methods

We estimated the number of women receiving perinatal psychosocial or psychological intervention in Japan. On December 2015, we requested 2,462 obstetrical facilities that are members of the Japan Association of Obstetricians and Gynecologists (JAOG) to provide information on women who received psychosocial or psychological intervention during pregnancy, the hospitalization period for childbirth and the puerperal 1 month in 2014. A total of 1,305 (53.0%) of the 2,462 obstetrical facilities responded with valid information on a total of 515,373 women, accounting for approximately 52% of all deliveries that occurred in Japan during the study period.

Results

The number of women who received psychosocial or psychological intervention during pregnancy, the hospitalization period for childbirth and the puerperal 1 month were 4,843 (0.94%), 4,791 (0.93%) and 3,015 (0.59%), respectively. In total, 8,743 women (1.70%) received psychosocial or psychological intervention in 2014.

Conclusion

Considering the response rate, the number of women requiring perinatal psychosocial or psychological intervention was estimated to be 16,000 per year in Japan.

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.
