Antenatal Risk Factors of Postpartum Depression at 20 Weeks Gestation in a Japanese Sample: Psychosocial Perspectives from a Cohort Study in Tokyo

Examination of risk factors for high Edinburgh postnatal depression scale scores: a retrospective study at a single university hospital in Japan

BACKGROUND

Perinatal mental health, such as postpartum depression, is an important issue that can threaten the lives of women and children. It is essential to understand the risk factors in advance and intervene before they can lead to postnatal depression. The risk factors of postpartum depression are reported to vary considerably in Japan. This study aimed to evaluate the risk factors for women with high Edinburgh Postnatal Depression Scale (EPDS) scores and to find women who may need our intervention to prevent postpartum depression.

METHODS

This was a retrospective observational study conducted at a single center. At the one-month check-up after birth, the EPDS test was performed in 1625 women who gave birth at our hospital from 2008 to 2016. We evaluated maternal, birth, neonatal and social factors and the breastfeeding status from medical records. Thereafter, we examined the factors that contributed to a high EPDS score.

RESULTS

There were 284 women in the high-score group with an EPDS of ≥ 9, and 1341 women in the low-score group with an EPDS score ≤ of 8. Maternal mental disorders and neonatal transport were significantly associated with high EPDS scores. Conversely, exclusive breastfeeding was significantly associated with the low-score EPDS group.

CONCLUSIONS

The principal factor for high EPDS scores was a mental disease. Based on this result, we suggest that early intervention in women at high risk for postpartum depression could prevent serious consequences such as abuse and suicide.

Association of perinatal factors with neurodevelopmental referrals in a population-based cohort study in Japan

Although the causes of neurodevelopmental disorders remain unknown, several environmental risk factors have attracted considerable attention. We conducted a retrospective, longitudinal, population-based cohort study using data from infant health examinations of children born to mothers with pregnancies between April 1, 2014 and March 31, 2016 in Kobe City to identify the perinatal factors associated with neurodevelopmental referrals in 3-year-old children. There were 15,223 and 1283 children in the normal and referral groups, respectively. Neurodevelopmental referrals at the health checkup for 3-year-old children were significantly associated with the lack of social support during pregnancy (adjusted odds ratio [aOR] 1.99, 99% CI 1.14-3.45, p = 0.001), history of psychiatric consultation (aOR 1.56, 99% CI 1.10-2.22, p = 0.001), no social assistance post-delivery (aOR 1.49, 99% CI 1.03-2.16, p = 0.006), Edinburgh Post-natal Depression Scale (EPDS) score ≥ 9 (aOR 1.36, 99% CI 1.01-1.84, p = 0.008), infant gender (male) (aOR 2.51, 99% CI 2.05-3.06, p < 0.001), and cesarean delivery (aOR 1.39, 99% CI 1.11-1.75, p < 0.001). In conclusion, this exploratory study in the general Japanese population identified six perinatal factors associated with neurodevelopmental referrals in 3-year-old children: infant gender (male), cesarean section, maternal history of psychiatric consultation, EPDS score ≥ 9, lack of social support during pregnancy, and no social assistance post-delivery.

Measurement of maternal morbidity during postpartum with the WHO-WOICE tools in Morocco

BACKGROUND

Maternal morbidity refers to any health problems or complications experienced by a woman during pregnancy, childbirth, or the postpartum period. Many studies have documented the, mostly negative, effects of maternal ill-health on functioning. Although, measurement of maternel morbidity remains underdeveloped. We aimed to evaluate the prevalence of non-severe maternal morbidities (including overall health, domestic and sexual violence, functionality, and mental health) in women during postpartum care and further analyze factors associated with compromised mental functioning and clinical health by administration of the WHO's WOICE 2.0 instrument.

METHODS

A cross-sectional study was conducted at 10 Health centers in Marrakech, Morocco with WOICE questionnaire included three sections: the first with maternal and obstetric history, sociodemographic data, risk and environment factors, violence and sexual health; the second considers functionality and disability, general symptoms and mental health; and the third includes data on physical and laboratory tests. This paper presents descriptive data on the distribution of functioning status among postpartum women.

RESULTS

A total of 253 women averaging 30 years of age participated. For self-reported health status of women, more than 40% reported good health, and just 9.09% of women had a health condition reported by the attending physician. Among postpartum women with clinical diagnoses, 16.34% had direct (obstetric) conditions and 15.56% indirect (medical) problems. When screening for factors in the expanded morbidity definition, about 20.95% reported exposure to violence. Anxiety was identified in 29.24% of cases, and depression in 17.78%. Looking into gestational results, just 14.6% delivered by cesarean section and 15.02% had preterm birth. We found also that 97% reported "good baby health" in the postpartum evaluation, with 92% of exclusive breastfeeding.

CONCLUSION

Considering these results, improving the quality of care for women requires a multi-faceted approach, including increased research, better access to care, and improved education and resources for women and healthcare providers.

[Associations between Maternal Postpartum Depression and Psychosocial Factors Including Marital Relationship and Social Support]

OBJECTIVES

We aimed to investigate the psychosocial factors for postpartum depression as indicated by a high score of the Edinburgh Postnatal Depression Scale (EPDS), including marital relationship and social support. Relevant factors for antenatal depression were also analyzed.

METHODS

Thirty-five wife-and-husband pairs who visited University Hospital A for the wife's antenatal health check-up participated in a questionnaire survey using the Japanese version of the EPDS. Social support from the wife's husband, kins, and others including friends at the third trimester of pregnancy and 1 month after birth was assessed. The Marital Love Scale (MLS) was also used, and two marital relationship questions were asked regarding the husband's and wife's considerate actions toward each other during pregnancy. Binary logistic regression analysis was conducted to determine adjusted associations between higher EPDS scores (≥5 for postpartum depression and ≥7 for antenatal depression) and indicators for social support and marital relationships.

RESULTS

The most relevant factor for higher postpartum EPDS scores was a higher antenatal EPDS score, followed by the couple's poor communication skills (the wife did not feel any appreciation from her husband) during pregnancy and no support from the wife's husband during the postpartum period. The wife's poor marital communication skills and the husband's low MLS scores during pregnancy were associated (borderline significance) with the wife's higher antenatal EPDS scores.

CONCLUSIONS

A good marital relationship before birth and support by the husband after birth may be important for preventing postpartum depression.

Changing risk factors for postpartum depression in mothers admitted to a perinatal center

BACKGROUND

The Edinburgh postnatal depression scale (EPDS) is commonly used in screening for major postpartum depression (PPD). We explored the clinical factors associated with score changes.

METHODS

Mothers (n=1,287) who delivered a single live-born infant in Kokura Medical Center in Japan during 2018-2019 were analyzed. The EPDS-Japanese version was conducted at the first and fourth weeks after childbirth. Scores of ≥9 were considered to indicate an increased risk of PPD.

RESULTS

The scores improved during the four-week period (5.03±0.12 to 3.79±0.10). Primiparity, Cesarean section (CS), and a low Apgar score were identified as initial risk factors, however, primiparity remained in the multivariate analysis (aOR 2.02, 95% CI 1.37-2.97). Age ≥35 years was associated with worsened scores (aOR 1.88, 95%CI 1.01-3.51), but CS improved (aOR 0.38, 95%CI 0.21-0.70). Primiparity, CS, and neonatal respiratory support were the initial risk factors, while infant anomaly was a late risk factor in mothers whose infants were admitted to the neonatal intensive care unit (NICU) (aOR 3.35, 95%CI 1.31-8.56). In mothers of infants with an NICU stay of ≥4 weeks, infant anomaly was associated with worsened scores (aOR 6.61, 95%CI 1.11-39.3), while respiratory support was associated with improved scores (aOR 0.09, 95%CI 0.01-0.65). Twenty-six mothrs with worsened scores received psychiatric support; three developed PPD. Two of the three were ≥35 years of age, neither of their infants had anomalies.

CONCLUSION

Maternal aging and infant anomaly were risk factors for PPD. PPD occurred in mothers with worsened EPDS scores after mental care. Puerperants with worsening risk factors should be targeted to control PPD.

Three spirals: Breastfeeding problems, growth spurts, and postpartum depression

PURPOSE

The inadequacy experienced in maintaining breastfeeding was tried to be understood within the framework of Meleis' theory, and its relationship with growth spurts and postpartum depression was attempted to be revealed.

DESIGN AND METHODS

The study was planned in a case-control type web-based descriptive research design. Mothers (n = 572), who thought that they experienced breastfeeding problems, constituted the case group of the study, and mothers (n = 524), who thought that they did not experience breastfeeding problems, constituted the control group.

FINDINGS

A statistically significant relationship was found between the case and control groups in terms of growth spurts and depression risk.

PRACTICE IMPLICATIONS

It is recommended to determine mothers' mood changes and breastfeeding problems they experience on the first postpartum days, to provide counseling to them.

Comprehensive intervention during pregnancy based on short message service to prevent or alleviate depression in pregnant women: A quasi-experimental study

AIM

Women have an increased risk for developing depression during pregnancy, and depression has a serious negative impact on the mother and infant. This study explored the effectiveness and feasibility of a comprehensive intervention based on using a short message service (SMS) to reduce depressive symptoms and prevent depression during pregnancy.

METHODS

This quasi-experimental study was conducted in three public hospitals with similar levels of care and maternal origin in Jiangmen City, Guangdong Province. One of the three hospitals was randomly selected as the intervention hospital, and the others were control hospitals. There were 4501 pregnant women who participated in this study. Pregnant women in the intervention group received a comprehensive intervention based on SMS after enrollment. Data were collected using questionnaires from August 2016 to August 2018.

RESULTS

After the intervention, the Edinburgh Postnatal Depression Scale scores of the intervention group were lower than those of the control group (intervention group: 3.9 ± 3.9, control group: 5.2 ± 4.3, P < .001), and the proportion of subjects with positive depression screening results in the intervention group was also significantly lower than that in the control group (intervention group: 9.0%, control group: 16.1%, P < .001). Moreover, compared with women in the intervention group, women in the control group who did not receive the intervention were more likely to be positive for depression in the third trimester (AOR = 2.04, 95% CI = 1.62-2.58).

CONCLUSIONS

The SMS-based comprehensive intervention used in this study can effectively alleviate depressive symptoms and reduce the risk of depression during pregnancy.

Antenatal and postnatal association of maternal bonding and mental health in Fukushima after the Great East Japan Earthquake of 2011:The Japan Environment and Children's Study (JECS)

BACKGROUND

Japan Environmental and Children's Study (JECS) was under way in Fukushima at the time of the triple disaster. It was initially to assess the effects of environmental factors on children's health, but given the situation particular to the accident, it could also offer an additional source of material with which to examine the psychological impacts of the disaster on mothers. This study aimed to examine the characteristics of mental health of Fukushima mothers after the triple disaster by comparing the scores in Fukushima with the nationwide scores. Then, it aimed to examine associations between their maternal bonding and mental health both during pregnancy and following birth.

METHODS

The JECS administered the Kessler 6-item psychological distress scale (K6) during pregnancy and the Edinburgh Postnatal Depression Scale (EPDS) 1 month following birth to 97 454 eligible women. In conjunction with the JECS, this study analysed the scores of 11 630 women in Fukushima which were obtained in the JECS between 2011 and 2015, and compared them with the nationwide scores during the same time period.

RESULTS

The proportion of mothers having 'negative feelings toward pregnancy' was significantly higher in Fukushima Regional centre (RC) than in the other 13 RCs between 2011 and 2014. No significant difference in the 'lack of affection' scores following birth was found between Fukushima RC and other RCs in 2012 and 2013, but the score in Fukushima RC was significantly lower in 2014 and 2015. The K6 scores in Fukushima RC were significantly higher than in other RCs in all years, and the EPDS scores following birth in Fukushima RC were also higher than in the 13 RCs in all years. The results of multivariate analysis showed a significant association between 'mothers' negative feelings toward pregnancy' and depressive symptoms, except in Fukushima RC in 2011. Also, it showed another significant association between 'lack of affection' and postpartum depressive symptoms from 2012 to 2015 in both Fukushima RC and 13 RCs. K6 scores during pregnancy were significantly associated with EPDS scores throughout the study period in both Fukushima RC and 13 RCs.

LIMITATIONS

Due to the lack of information on participants' residential region at the municipal level in the JECS, it was unable to measure regional differences within Fukushima prefecture.

CONCLUSION

This study shed light on the relationship between maternal bonding and mental health both during pregnancy and following birth by using the sequential and periodic national data sets. While showing the maternal characteristics associated with depressive symptoms during pregnancy and following birth in Japan, it distinguished the characteristics between Fukushima and nationwide. It raised the possibility that providing mothers in Fukushima with supports to increase their bonding toward their pregnancy could prevent the development of depressive tendency. The results could suggest that not only depression prevention measures but also maternal bonding support could be necessary in the region.

The magnitude of postpartum depression among mothers in Africa: a literature review

Introduction

postpartum depression (PPD) continues to become one of the major maternal health challenges across the globe but there is a paucity of recent data on its magnitude in Africa. This study was motivated by the need to update the current magnitude of PPD in Africa based on various assessment tools.

Methods

a total of 21 articles met the study criteria. Fifteen articles used the EPDS and six used other assessment tools. Postpartum depression among studies that used EPDS tool ranged from 6.9% in Morocco to 43% in Uganda and 6.1% in Uganda to 44% in Burkina Faso among studies that used other depression assessment tools. Sensitivity and specificity results of the EPDS ranged from 75%-100% and 87%-98% respectively.

Results

a total of 21 articles met the study criteria. Fifteen articles used the EPDS and six used other assessment tools. Postpartum depression among studies that used EPDS tool ranged from 6.9% in Morocco to 43% in Uganda and 6.1% in Uganda to 44% in Burkina Faso among studies that used other depression assessment tools. Sensitivity and specificity results of the EPDS ranged from 75%-100% and 87%-98% respectively.

Conclusion

despite the limited dearth of literature, the magnitude of PPD in Africa remains high which suggests that PPD is still a neglected illness and calls for immediate interventions. EPDS is an effective tool with high sensitivity and specify in varying study contexts.

An integrated community mental healthcare program to reduce suicidal ideation and improve maternal mental health during the postnatal period: the findings from the Nagano trial

BACKGROUND

During the perinatal period, suicides are more likely to occur in those with depression and who are not receiving active treatment at the time of death. Suicide is a common outcome in people with suicide ideation. We developed an intervention program taking care of comprehensive perinatal maternal mental healthcare to prevent suicide ideation. We hypothesized that our intervention program could reduce postnatal suicide ideation and improve maternal mental health.

METHODS

We performed a controlled trial to examine the usual postnatal care plus a maternal suicide prevention program (the intervention group) compared with usual postnatal care alone, which comprised home visits by public health nurses without mental health screening (the control group) in Nagano city, Japan. In total, 464 women were included; 230 were allocated to the control group and 234 to the intervention group. The intervention had three components: 1) all the women received postnatal mental health screening by public health nurses who completed home visits during the neonatal period, 2) the intervention was administered by a multidisciplinary clinical network, and 3) systematic follow-up sheets were used to better understand bio-psycho-social characteristics of both the mothers and their infants and develop responsive care plans. We measured the participants' mental health at 3-4 months postpartum (T1) and 7-8 months postpartum (T2) using the Japanese version of the Edinburgh Postnatal Depression Scale (EPDS).

RESULTS

Suicidal ideation was significantly lower in the intervention group compared with the control group at T1 (p = 0.014); however, this significant between-group difference did not continue to T2 (p = 0.111). We measured the intervention effects on maternal mental health using the total score of the EPDS, which was significantly improved in the intervention group compared with the control group at T1. Here, the significant difference continued to T2 (p = 0.049).

CONCLUSIONS

Our results indicate that our program may reduce maternal suicidal ideation at 3-4 months postnatally and improve women's mental health during the postnatal periods of 3-4 to 7-8 months. Postnatal maternal mental healthcare, including services to reduce suicide ideation, should be included as an important component of general postnatal care.

Multilevel analysis of the impact of neighborhood environment on postpartum depressive symptoms

BACKGROUND

About one in ten mothers experience postpartum depression (PPD) in Japan. Although the individual and social risk factors of depression have been reported, few studies have focused on the neighborhood environmental features. In this study, we examined the association between neighborhood environmental features and PPD symptoms among Japanese women.

METHODS

Questionnaire survey including women who participated in 3- or 4-month health checkup in Nagoya City, Japan in 2012 was used. PPD symptoms were evaluated using Edinburgh Postnatal Depression Scale (EPDS). As the neighborhood places where postpartum mothers often visit, we measured availability of grocery stores, community centers and asobiba (playground for children) within residential neighborhood unit using geographic information system. A multilevel analysis was conducted on 2,298 individuals nested within 388 school districts using Stata 15.1 software.

RESULTS

Mothers who live in the neighborhood with more number of asobiba had lower EPDS score, even after adjustment for individual factors (B: -0.12, 95%CI: -0.24, -0.01), and additional adjustment for other neighborhood environmental factors (B: -0.14, 95%CI: -0.27, -0.02).

LIMITATION

Our cross-sectional design limits to draw causal inferences. As for the evaluation of PPD symptoms, no diagnosis has been made. Moreover, we do not have the information on the accessibility to transportation, and the exact residential location of the survey respondents.

CONCLUSION

Our findings suggest that the availability of asobiba in the community has a protective effect on PPD symptoms. Providing more asobiba in the neighborhood for new mothers may be a viable preventive strategy for PPD symptoms.

Prevalence of perinatal depression among Japanese women: a meta-analysis

BACKGROUND

Perinatal depression is one of the important mental illnesses among women. However, not enough reviews have been done, and a certain consensus has not been obtained about the prevalence of perinatal depression among Japanese women. The purpose of our study is to reveal the reliable estimates about the prevalence of perinatal depression among Japanese women.

METHOD

We searched two databases, PubMed and ICHUSHI, to identify studies published from January 1994 to December 2017 with data on the prevalence of antenatal or postnatal depression. Data were extracted from published reports.

RESULTS

We reviewed 1317 abstracts, retrieved 301 articles and included 123 studies. The point prevalence of postpartum depression at 1 month was 14.3% incorporating 108,431 Japanese women. The period prevalence of depression at pregnancy was 14.0% in the second trimester and 16.3% in the third trimester. The period prevalence of postpartum depression was 15.1% within the first month, 11.6% in 1-3 months, 11.5% in 3-6 months and 11.5% in 6-12 months after birth. We also identified that compared with multiparas, primiparas was significantly associated with a higher prevalence of postpartum depression; the adjusted relative risk was 1.76.

CONCLUSIONS

The prevalence of postpartum depression at 1 month after childbirth was found to be 14.3% among Japanese women. During pregnancy, the prevalence of depression increases as childbirth approaches, and the prevalence of depression was found to decrease in the postpartum period over time. In addition, we found that the prevalence of postpartum depression in primiparas was higher than that in multiparas. Hence, we suggest that healthcare professionals need to pay more attention to primiparas than multiparas regarding postpartum depression.

Characteristics and changes in the mental health indicators of expecting parents in a couple-based parenting support program in Japan

Postpartum depression is a serious problem not only for mothers, but also for their children and families. Evidence is scarce on the effectiveness of couple-targeted antenatal interventions aimed at preventing postpartum depression in Asia. Therefore, we implemented an antenatal parenting support program from Australia ("empathy program") at three sites in Japan, and assessed the characteristics of participating couples and changes in their mental health indicators before and after the program (during pregnancy and 6 weeks postpartum, respectively). In this program, participant couples discussed concerns during pregnancy and a "difficult day" scenario with other same-gender participants and then with their own partners. In total, 100 couples attended the program. Among 60 participating mothers, 20% screened positive for maternal depression symptoms (defined as an Edinburgh Postnatal Depression Scale greater than 9). Changes in paternal empathy and maternal antenatal Edinburgh Postnatal Depression Scale score were significantly associated with maternal postpartum Edinburgh Postnatal Depression Scale score in multivariable analyses. Our results indicate that a key in preventing postpartum depression is paternal involvement and long-term support from antenatal phase.

Prenatal Depression and Its Associated Risk Factors Among Pregnant Women in Bangalore: A Hospital Based Prevalence Study

Background: Depression is the commonest psychological problem that affects a woman during her perinatal period worldwide. The risk of prenatal depression increases as the pregnancy progresses and clinically significant depressive symptoms are common in the mid and late trimester. There is a paucity of research on depression during the prenatal period in India. Given this background, the present study aimed to assess the prevalence of prenatal depression and its associated risk factors among pregnant women in Bangalore, Southern India. Methods: The study was nested within an on-going cohort study. The study participants included 280 pregnant women who were attending the antenatal clinic at Jaya Nagar General Hospital (Sanjay Gandhi Hospital) in Bangalore. The data was collected by using a structured questionnaire which included. Edinburgh Postnatal Depression Scale (EPDS) to screen for prenatal depression. Results: The proportion of respondents who screened positive for prenatal depression was 35.7%. Presence of domestic violence was found to impose a five times higher and highly significant risk of developing prenatal depression among the respondents. Pregnancy related anxiety and a recent history of catastrophic events were also found to be a positive predictors of prenatal depression. Conclusion: The high prevalence of prenatal depression in the present study is suggestive of its significance as a public health problem. Health care plans therefore can include screening and diagnosis of prenatal depression in the antenatal care along with other health care facilities provided.

The impact of resilience on prenatal anxiety and depression among pregnant women in Shanghai

BACKGROUND

Prenatal anxiety/depression has been a major public health problem globally with higher prevalence in developing countries, which leads to negative health outcomes for both mothers and children. Maternal stress varies over the course of pregnancy and the stress occurring in early pregnancy is the most critical. However, few studies have focused on the impact of resilience to stress on mental health of pregnant women.

AIMS

To explore the effect of resilience to stress on prenatal anxiety/depression in pregnant women.

METHODS

2813 participants were recruited from Shanghai Maternal-Child Pairs Cohort (Shanghai MCPC) in this study. The Life Event Scale for Pregnancy Women (LESPW) was used to assess stress at 12-16 weeks of pregnancy and at 32-36 weeks of pregnancy, respectively. Resilience was assessed by the revised Resilience Scale for Adults (RSA) at 12-16 weeks of pregnancy. The prenatal anxiety and depression were assessed at 32-26 weeks of pregnancy by Self-Rating Anxiety Scale (SAS) and the Center for Epidemiological Survey, Depression Scale (CES-D), respectively. Hierarchical linear regression analyses were conducted to explore the direct effect of stress and resilience on prenatal anxiety and depression. The indirect effects of mediation were analyzed by structural equation models, and the indirect effect of modification was examined by stratification analysis.

RESULTS

There were 11.1% and 10.3% of pregnant women in Shanghai MCPC indicating anxiety and depressive mood, respectively. The stress caused by both subjective and objective events at 32-36 weeks of pregnancy is less than that at 12-16weeks of pregnancy. We found that resilience was a protective factor for maternal mental health and meanwhile it was both an effect modifier and a mediator to the association between stress and prenatal anxiety/depression, with the mediating effect ratio of 15.1% and 23.8%, respectively.

LIMITATIONS

The existence of recall bias, missing data, and restricted residential areas of the participants may limit the generalizability of the study. The measurements of resilience, prenatal anxiety, and depression were not designed specifically for pregnant women, so that they might have missed some important indications of mental issues related to pregnant women only.

CONCLUSIONS

Resilience could be a direct and indirect protective factor for prenatal anxiety and depression caused by pregnancy stress.

Maternal Depression Scale: Do "Drop-In" Laborist Patients Have Increased Postpartum Screening Risks Compared to Patients with Adequate Prenatal Care?

Objectives The Edinburgh Postnatal Depression Scale (EPDS) identifies women with depressive symptoms in pregnancy. Our primary objective was to determine the prevalence of EPDS screen-positive women delivering on our no prenatal care (laborist) service and to compare these patients to private patients delivering with prenatal care. Methods Retrospective cohort analysis of EPDS scores during January 1, 2015 to June 18, 2015 was conducted. Scores ≥ 10 were considered at-risk. Results were analyzed as an aggregate and then as no prenatal care versus prenatal care. Characteristics for patients with at-risk scores (EPDS ≥ 10) versus low-risk scores (EPDS < 10) were quantified. Results Analysis occurred on 970 women. EPDS ≥ 10 occurred in 12.4% (n = 120/970). Positive EPDS score was 21.1% without prenatal care versus 10.9% with adequate prenatal care (P = 0.003). Maternal demographics and delivery characteristics were clinically similar in patients with prenatal care compared to no prenatal care. Private insurance was more common in patients with prenatal care compared to no prenatal care (23.5 versus 8.1%, P = 0.0001). However, analysis of patients with EPDS > 10 showed non-significant distributions of ethnicity, private insurance, Medicaid, or no insurance compared to patients with EPDS < 10. Conclusion for Practice Patients without prenatal care who arrive solely for urgent "drop-in" delivery have a measurable increased risk factor for postpartum depressive symptoms. Ethnicity and payor status were related to adequacy of prenatal care but were not significant variables when analyzing patients with EPDS > 10. Laborist services providing care to "drop-in" patients should recognize this increased risk and develop policies for screening, referral and follow-up of at-risk patients.

Integrated mental health care in a multidisciplinary maternal and child health service in the community: the findings from the Suzaka trial

Background

Perinatal mental health problems such as mood disorders are common. We propose a new multidisciplinary health service intervention program providing continuous support to women and their children from the start of pregnancy till after childbirth. The aim of this study was to examine the effects of the program with respect to making women’s mental health better in the postpartum period and improving the state of care for women and their children in the perinatal period.

Methods

We performed a controlled study to investigate the effectiveness of the program in Suzaka City, Japan. The women’s mental health status was assessed using the Edinburgh Postnatal Depression Scale (EPDS) 3 months postpartum. Of 349 women, 210 were allocated to the intervention group and 139 to the control group. From April 2014 to March 2015, the number of the pregnant women who were followed-up by the multidisciplinary meeting in the intervention and control groups were 60 and 4, respectively. In the same period, the number of the pregnant women who were identified as requiring intensive care were 21 and 2, respectively.

Results

The total EPDS score, which was the primary outcome of the present study, differed significantly between the intervention and control groups (Mean [SD] = 2.74 (2.89) and 4.58 [2.62], respectively; p < 0.001). The number of the women receiving counseling from a public health nurse (5.3% in intervention group, 0.7% in control group, p = 0.02), attending maternal seminars (attendant ratio: 46% whereas 16%, p = 0.01), and receiving home visits by public health nurses (home visit ratio: 93.8% whereas 82.6%, p < 0.001) was significantly higher in the intervention group compared to the control group.

Conclusions

The present study indicates that continuum support provided by integrated mental health care through a multidisciplinary maternal and child health service in the community can make women's mental health better in the postpartum period and help women and their children receive more health services from public health nurses.

Postnatal depressive symptoms in women with and without antenatal depressive symptoms: results from a prospective cohort study

Evidence exists that the risk factors for depression in the antenatal and postnatal period may differ, but only a handful of studies looked at depression longitudinally. The aims of this study were (1) to estimate the prevalence of postnatal depressive symptoms in Kuwait where data about postnatal depression are scarce and identify its determinants and (2) to compare these risk factors between women who had experienced antenatal depressive symptoms and those that did not. Data collected in the TRansgenerational Assessment of Children's Environmental Risk (TRACER) Study in Kuwait were used in this analysis. The sample was restricted to the 1348 women who answered the Edinburgh Postnatal Depression Scale (EPDS) both antenatally and postnatally. The prevalence of postnatal depressive symptoms, defined by an EPDS score ≥ 10, was 11.7%. Overall, antenatal depressive symptoms were the strongest determinant of postnatal depressive symptoms. Multivariable logistic regression analysis showed that in women with depressive symptoms in pregnancy, having a lower household income was the most significant risk factor for postnatal depressive symptoms. Among women without antenatal depressive symptoms, those who had lower income, were Kuwaitis, experienced other problems in pregnancy such as perceived stress, PTSD symptoms and social isolation, and those who delivered a boy had higher odds of postnatal depressive symptoms. Antenatal depressive symptoms and other psychosocial characteristics can predict postnatal depressive symptoms. Therefore, maternal mental health issues should be detected during the antenatal period and support should be provided in order to lower the risk of postnatal depression and its sequelae.

Maternal violence experiences and risk of postpartum depression: A meta-analysis of cohort studies

BACKGROUND

Most of original studies indicated maternal violence experiences is associated with adverse obstetric outcomes, to date, but it is not clear that the association of maternal violence experiences and the risk of postpartum depression (PPD). We aimed to assess the association between maternal violence experiences and risk of developing PPD by performing a meta-analysis of cohort studies.

METHODS

PubMed, Google Scholar, Cochrane Libraries and Chinese databases were searched through December 2017 to identify studies that assessed the association between violence and PPD. Meta-analysis was conducted by the RevMan software and Stata software. Potential heterogeneity source was explored by subgroup analysis and potential publication bias was assessed by Begg's funnel plots and Egger's linear regression test.

RESULTS

Overall, women experiencing any violence events compared with the reference group were at a higher risk of developing PPD (odds ratio [OR] = 2.04; 95% confidence interval [CI]: 1.72-2.41). Additionally, different types of violence events such as sexual (OR = 1.56; 95%CI: 1.35-1.81), emotional (OR = 1.75; 95%CI: 1.61-1.89), and physical violence (OR = 1.90; 95%CI: 1.36-2.67), as well as domestic (OR = 2.05; 95%CI: 1.50-2.80) or childhood violence (OR = 1.59; 95%CI: 1.34-1.88) also increased the risk of developing PPD. Relevant heterogeneity moderators have been identified by subgroup analysis. Sensitivity analysis yielded consistent results.

CONCLUSIONS

Maternal violence experiences are significantly associated with risk of developing PPD. These finding highlight the necessary to protect women from any types of violence and formulate preventive strategies to promote the maternal mental health.

Standardizing the measurement of maternal morbidity: Pilot study results

Objective

To field test a standardized instrument to measure nonsevere morbidity among antenatal and postpartum women.

Methods

A cross‐sectional study was conducted in Jamaica, Kenya, and Malawi (2015–2016). Women presenting for antenatal care (ANC) or postpartum care (PPC) were recruited if they were at least 28 weeks into pregnancy or 6 weeks after delivery. They were interviewed and examined by a doctor, midwife, or nurse. Data were collected and securely stored electronically on a WHO server. Diagnosed conditions were coded and summarized using ICD‐MM.

Results

A total of 1490 women (750 ANC; 740 PPC) averaging 26 years of age participated. Most women (61.6% ANC, 79.1% PPC) were healthy (no diagnosed medical or obstetric conditions). Among ANC women with clinical diagnoses, 18.3% had direct (obstetric) conditions and 18.0% indirect (medical) problems. Prevalences among PPC women were lower (12.7% and 8.6%, respectively). When screening for factors in the expanded morbidity definition, 12.8% (ANC) and 11.0% (PPC) self‐reported exposure to violence.

Conclusion

Nonsevere conditions are distinct from the leading causes of maternal death and may vary across pregnancy and the puerperium. This effort to identify and measure nonsevere morbidity promotes a comprehensive understanding of morbidity, incorporating maternal self‐reporting of exposure to violence, and mental health. Further validation is needed.

A pilot study of a novel instrument to holistically measure maternal morbidity found that nonsevere conditions are distinct from the leading causes of maternal death.

Perinatal Depression and Associated Factors among Mothers in Southern Ethiopia: Evidence from Arba Minch Zuria Health and Demographic Surveillance Site

Background. Perinatal depression is a serious mental health problem that can negatively affect the lives of women and children. The adverse consequences of perinatal depression in high-income countries also occur in low-income countries. Objective. To assess the perinatal depression and associated factors among mothers in Southern Ethiopia. Methods. A community based cross-sectional study was conducted among selected 728 study participants in Arba Minch Zuria HDSS. A pretested questionnaire was used to collect the data. Data were analyzed using STATA version 12 software. Descriptive statistical methods were used to summarize the characteristics of the mothers. Bivariate and multivariable logistic regression was used for analysis. Results. The prevalence of perinatal depression among the study period was 26.7%. In the final multivariable logistic regression, monthly income AOR (95% C.I): 4.2 (1.9, 9.3), parity [AOR (95% C.I): 0.14 (0.03, 0.65)], pregnancy complications AOR (95% C.I): 5 (2.5, 10.4), husband smoking status [AOR (95% C.I): 4.12 (1.6, 10.6)], history of previous depression AOR (95% C.I): 2.7 (1.54, 4.8), and family history of psychiatric disorders were the independent factors associated with perinatal depression. Conclusion. The study showed a high prevalence of perinatal depression among pregnant mothers and mothers who have less than a one-year-old child.

A longitudinal study of perinatal depression among Chinese high-risk pregnant women

BACKGROUND

Information is needed on the prevalence of depression in Chinese women with medically defined complications across the perinatal period, as well as key risk factors to develop appropriate perinatal mental health services and ensure the services target those most in need.

AIM

The goal of this study was to examine whether women's perinatal depression scores change across the perinatal period and evaluate risk factors associated with postnatal depression at 6-weeks after delivery.

METHODS

A sample of 167 Chinese pregnant women with medically defined complications and an Edinburgh Postnatal Depression Scale≥9 and/or a Postpartum Depression Screening Scale≥60 were followed throughout early pregnancy (<28 weeks), late pregnancy (>28 weeks), 3-days and 6-weeks after delivery.

FINDINGS

Repeated measures analysis of variance showed that there were significant differences on the Edinburgh Postnatal Depression Scale and Postpartum Depression Screening Scale scores at each time point between high-risk depressed and low-risk depressed groups. Binary logistic regression indicated a significant association between postnatal depression at 6-weeks after delivery and depression in late pregnancy and 3-days after delivery, postnatal stress events, postnatal complications, and concerns about the fetus.

CONCLUSIONS

Postnatal depression is a common condition with limited research among Chinese pregnant women with medically defined complications. Additional research is warranted to develop strategies to identify high-risk depressed pregnant women as well as effective treatment options during the perinatal period.

Cross-National Differences in Psychosocial Factors of Perinatal Depression: A Systematic Review of India and Japan

Perinatal depression is prevalent worldwide. However, there are few available studies that discuss the different cultural factors affecting perinatal depression within Asian countries. This study aims to compare the literature regarding related factors relating to perinatal depression in India and Japan, and to synthesize the evidence common to both countries in addition to the country-specific evidence. We conducted a systematic review using several databases (CINAHL, MEDLINE, Pubmed, Ovid, SCOPUS, IndMED, and ICHUSI). Keywords were “antenatal depression” or “postpartum depression”, and “India” or “Japan”. Both Japanese and English language papers were reviewed. The identified evidence was compared between the two countries, as well as with non-Asian countries based on previous reports. In total, 15 articles on India and 35 on Japan were reviewed. Although several factors were shared between the two countries as well as with other non-Asian countries (vulnerable personality, being abused, age, marital conflict, and lower socio-demographic status), some differing factors were identified between India and Japan and non-Asian countries; India: poor socioeconomic status, living only with the husband, pregnancy not welcomed by the husband, a female baby, and poor relationship with in-laws; Japan: infertility treatment, conflict with work–life balance, poor relationships with biological mother or in-laws, and concerns about social relations with the other mother’s friends. To conclude, involving the family and community may be important for implementing both global standardized and culture-specific interventions. In India, treatment involving the in-laws may be effective because large family structure is a significant predictor of perinatal depression. In Japan, a family/community approach involving not only the mother’s family of origin but also the working environment is essential.

Preconception gynecological risk factors of postpartum depression among Japanese women: The Japan Environment and Children's Study (JECS)

BACKGROUND

Postpartum depression is one of the major causes of disability among women who are on their childbearing years. Identifying people at risk of postpartum depression may improve its management. The objective of this study was to determine the probable association between postpartum depression and some preconception gynecological morbidities.

METHODS

Data from a nationwide birth cohort study, the Japan Environment and Children's study (JECS), up to one month of postpartum were analyzed. To assess postpartum depression, the Edinburgh Postnatal Depression Scale (EPDS) was used; 11 preconception gynecological morbidities were considered as risk factors. Covariates included psychiatric illness history, psychosocial factors, some pregnancy adverse outcomes, birth outcomes, socio-demographic and health behavioral factors.

RESULTS

Except for the prevalence of previous miscarriage, leiomyoma and polycystic ovarian syndrome, depressive women had more gynecological morbidities compared to non-depressive ones. In logistic regression model, endometriosis (OR, 1.27; 95%CI: 1.15-1.41), dysmenorrhea (OR, 1.13; 95%CI: 1.06-1.21) and abnormal uterine bleeding (OR, 1.21; 95%CI: 1.15-1.29) were associated with postpartum depression.

LIMITATIONS

CONCLUSION: Women with endometriosis and menstrual problems were at risk of developing postpartum depression. This study suggests a perinatal mental health screening for predisposed women.

A randomized controlled trial: effects of a prenatal depression intervention on perinatal outcomes among Chinese high-risk pregnant women with medically defined complications

Prenatal psychosocial health has been linked with health behaviors, maternal health, and birth outcomes. This randomized controlled trial evaluated the effects of a prenatal depression intervention on birth outcomes and maternal physical and psychological status at 42 days postpartum. Three hundred fifty-two high-risk pregnant women exposed to obstetric complications with an Edinburgh Postnatal Depression Scale (EPDS) ≥ 9 or a Postpartum Depression Screening Scale (PDSS) ≥ 60 were randomly assigned to the intervention group (n = 176) and control group (n = 176). The intervention group underwent a six-session couple-separated psycho-educational program; the control group received the usual care. All participants were asked to complete questionnaires at late pregnancy (>28 weeks), 3 days postpartum, and 42 days postpartum. The intervention group had a significantly lower cesarean rate and shorter third stage of labor (p < .05). At 42 days after delivery, only 5.1% of participants were lost to follow-up, and the intervention group had significantly less minor and major depression, more sleep time, more satisfaction with their husband and other family members, less concern about taking care of baby, and less breast milk insufficiency than the control group (p < .05). A prenatal psychological intervention model for high-risk pregnant women holds potential as a preventive program that addresses maternal health and birth outcomes.

Antenatal depressive symptoms among pregnant women: Evidence from a Southern Brazilian population-based cohort study

BACKGROUND

Antenatal depression (AD) is a major public health issue but evidence regarding its prevalence and associated factors in low and middle-income countries (LMICs) is limited. The aim of the study was to estimate the prevalence and identify risk factors for AD among Brazilian pregnant women.

METHODS

All women living in the urban area of the city of Pelotas, Southern Brazil, with confirmed pregnancy and estimated delivery date in the year 2015, were invited to take part. Eligible pregnant women were recruited from health services. Symptoms of antenatal depression were assessed using the Edinburgh Postnatal Depression Scale (EPDS) by face-to-face interviews. A cutoff-point of 13 or more was used to define probable AD.

RESULTS

EPDS scores were available for 4130 women. The prevalence of AD was 16% (95%CI 14·9-17·1). After adjustment for potential confounders, the factors most strongly associated with higher EPDS scores were a previous history of depression (PR 2·81; 95%CI 2·44-3·25), high parity (PR 1·72; 95%CI 1·38-2·15 - ≥2 children vs. 1 child) and maternal education (PR 5·47; 95%CI 4·22-7·09 - 0-4 vs. ≥12 years of formal education).

LIMITATIONS

EPDS was administered through face-to-face interviews rather than questionnaires and some women may have felt uncomfortable reporting their symptoms leading to underreporting and consequently underestimation of the prevalence found.

CONCLUSION

AD prevalence is substantially higher in Brazil than in high-income countries (HICs) but similar to other LMICs. Our study identified relevant risk factors that may be potential targets to plan interventions, particularly a history of depression.

Antenatal depression and hematocrit levels as predictors of postpartum depression and anxiety symptoms

The aim of this study is to delineate the risk factors of antenatal depression and its consequences, including postnatal depression, and to examine whether the hematocrit (Hct) is associated with maternal depression. The Edinburgh Postnatal Depression Scale (EPDS), Spielberger's State Anxiety Inventory (STAI), Kennerley and Gath Maternity Blues Assessment Scale (KGB), Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HAMD) were assessed at the end of term (T1) and 2-3 days (T2) and 4-6 weeks (T3) after delivery in 126 women with and without antenatal depression. The Hct was measured at T1. Antenatal depression was significantly predicted by lifetime depression and premenstrual syndrome and less education. Antenatal depression was not associated with obstetric or neonatal outcomes. Antenatal depression symptoms strongly predict depression and anxiety symptoms at T2 and T3. The EPDS, KGB, STAI and BDI, but not the HAMD, scores, were significantly lower at T3 than before. The incidence of depression significantly decreased from T1 (23.8%) to T2 (7.8%) and T3 (5.3%). T1 Hct values significantly predicted the T3 postnatal EPDS, STAI, KGB and BDI scores. Delivery significantly improves depression and anxiety symptoms. Increased Hct in the third trimester is a biomarker of postpartum depression and anxiety symptoms.
