Optimal cut-off score of the Edinburgh Postnatal Depression Scale for major depressive episode during pregnancy in Japan

Proposing a two-stage screening approach to distinguish between transient and enduring postnatal depressive symptoms: A prospective cohort study

Background

Screening for perinatal depression using the Edinburgh Postnatal Depression Scale (EPDS) improves detection and increases health service utilization. However, previous studies with antenatal samples indicate that positive screenings might reflect transient distress that resolves without intervention, raising concerns about over-pathologizing typical postnatal responses and inefficiencies in referral practices. Therefore, distinguishing between transient and enduring depressive symptoms for appropriate referrals to secondary services is crucial, highlighting the need for a refined screening practice.

Objectives

We aimed to assess the prevalence of transient distress among postnatal women who initially screened positive on the EPDS and evaluate the effectiveness of a refined two-stage screening approach. Three research questions were addressed: Can the "transient phenomenon" be replicated in a postnatal sample? Can initial screening data predict transient status? What are the implications of adopting a two-stage screening approach?

Methods

In a prospective cohort study, 427 postnatal women in Copenhagen who scored above the cut-off on their initial EPDS screening (EPDS-1) underwent a second screening (EPDS-2) 1-4 weeks later, without intervention in between. We analyzed the predictive power for transient versus enduring distress using EPDS-1 total scores, responses to item 10 ("self-harm item"), parity, maternal age, and a history of depression. Three screening scenarios were compared for their clinical and ethical implications: (i) a traditional single screening approach where all individuals screening positive at EPDS-1 are directly referred to secondary services, (ii) a simple two-stage approach where all positive screenings at EPDS-1 undergo a second screening before referral, and (iii) a refined two-stage screening approach where selected criteria determine immediate referral or further screening.

Results

Among women who screened positive, 29.3 % displayed transient distress with a clinically meaningful decrease in EPDS scores. An EPDS-1 score of 15 or more was the most robust predictor of enduring symptoms (OR = 6.28, 95 % CI 3.5-11.8; Absolute Risk = 90.4 %) and was used along with a positive score on item 10 as indicators of immediate referral in scenario-iii. The refined two-stage approach reduced unnecessary referrals by 24 %, directly referred 60 % of women with enduring symptoms, and effectively managed suicidal risk.

Conclusions

A substantial proportion of postnatal women experience transient symptoms that are distinguishable from enduring symptoms through a refined two-stage screening strategy. This approach significantly improves referral efficiency and minimizes over-pathologization, enhancing clinical practice in perinatal mental health.

Restless legs syndrome without insomnia and antenatal depressive symptoms

BACKGROUND

Restless legs syndrome (RLS) with insomnia is presumed to be associated with antenatal depression. RLS without insomnia, however, has not been investigated in association with antenatal depression. We aimed to examine whether RLS without insomnia during pregnancy is associated with antenatal depressive symptoms.

METHODS

This cross-sectional study used data from a randomized controlled trial (RCT) assessing antenatal depressive symptoms among Japanese pregnant women. The participants were 2,108 women who attended the RCT at 16-20 weeks of pregnancy. RLS, insomnia, and antenatal depressive symptoms were assessed using the Cambridge-Hopkins questionnaire short form, Insomnia Severity Index, and Edinburgh Postnatal Depression Scale, respectively. Associations of antenatal depressive symptoms with RLS and insomnia were examined using logistic regression analysis, adjusting for age, partner, education, children, and planned pregnancy.

RESULTS

Of the total participants, 206 (9.8%) had antenatal depressive symptoms; 80 (3.8%) had RLS. The mean age (standard deviation) was 30.4 (4.6) years. RLS was positively associated with antenatal depressive symptoms: the odds ratio was 2.30 (95% confidence interval, 1.28-4.16). RLS without insomnia was positively associated with antenatal depressive symptoms, as well as insomnia without RLS and RLS with insomnia: the odds ratio was 2.44 (95% confidence interval, 1.09-5.46) for RLS without insomnia, 3.83 (2.78-5.28) for insomnia without RLS, and 5.80 (2.42-13.92) for RLS with insomnia, compared to neither RLS nor insomnia.

CONCLUSIONS

We observed the positive association between RLS without insomnia and antenatal depressive symptoms, suggesting the importance of assessing and treating RLS without insomnia during pregnancy for the reduction of antenatal depressive symptoms.

Ten-year trajectories of postpartum depression of Japanese mothers and fathers

BACKGROUND

Perinatal depression is a significant concern affecting both women and men during pregnancy and postpartum periods. While maternal postpartum depression has been extensively studied, paternal depression remains under-researched despite its prevalence and impact on family well-being. This study aimed to estimate the trajectories of perinatal and postpartum depression in Japanese parents over ten years and to determine the details of the symptoms of postpartum depression for each trajectory group, considering reciprocal effects between maternal and paternal depression.

METHODS

A total of 789 couples used the Edinburgh Postnatal Depression Scale to rate their depressive symptoms prenatally; at 5 weeks, 3 months, 6 months, and 1 year postpartum; and then yearly thereafter until the 10th year. Parallel-process latent class growth analysis was used to group participants according to their longitudinal patterns of depressive symptoms.

RESULTS

For both mothers and fathers, four depressive symptom trajectories fit the data best and were most informative (escalating: 6.5 %; mothers low and fathers moderate: 17.2 %; mothers high and fathers low: 17.9 %; low: 58.4 %). A variance analysis showed significant class-parent interactions across anhedonia, anxiety, and depression subscales, indicating distinct patterns of depressive symptomatology.

DISCUSSION

Tailored mental health programs and universal screening using the Edinburgh Postnatal Depression Scale are recommended to address the specific needs of each trajectory class. This study contributes to the understanding of long-term depressive symptom trajectories in parents and emphasizes the necessity of comprehensive support strategies to enhance family well-being and resilience.

Association of preconception premenstrual disorders with perinatal depression: an analysis of the perinatal clinical database of a single Japanese institution

BACKGROUND

Recent studies have identified premenstrual disorders (PMDs) as a risk factor for postpartum depression. However, routine screening for preconception PMDs is not yet common in Japan. This study investigated the association between preconception PMDs and perinatal depression in a single tertiary care setting.

METHODS

We analyzed data from pregnant women who gave birth at Kyoto University Hospital between April 2020 and October 2023. The Premenstrual Symptoms Screening Tool was administered at the first postconception visit to retrospectively assess PMD status before the current pregnancy. The Edinburgh Postnatal Depression Scale (EPDS) was administered during pregnancy and one month postpartum as a prospective measure of perinatal depression. EPDS cutoff values were set at 12/13 during pregnancy and 8/9 at one month postpartum.

RESULTS

Of the 781 women analyzed, 53 had preconception PMD. Univariate and multivariate logistic regression analyses revealed that preconception PMD was associated with an EPDS score of ≥ 13 during pregnancy, with a crude odds ratio (OR) of 5.78 (95% confidence interval [CI]: 2.70-11.75) and an adjusted OR of 3.71 (95% CI: 1.54-8.35). For an EPDS score of ≥ 9 at 1 month postpartum, the crude OR was 3.36 (95% CI: 1.79-6.12) and the adjusted OR was 2.16 (95% CI: 1.04-4.35).

CONCLUSIONS

Our findings indicate that preconception PMDs are a significant risk factor for both depression during pregnancy and postpartum depression. These results support the implementation of preconception PMD screening during antenatal checkups as a preventive measure and to identify women in need of early mental health care.

Impact of premenstrual syndrome and premenstrual dysphoric disorder on maternal antenatal depression

In this study, we aimed to determine the association of premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD) with maternal antenatal depression. This cross-sectional, online questionnaire-based observational study included 212 pregnant women between gestational ages 24 weeks and 28 weeks 6 days. PMS and PMDD were measured using the PMDD Scale, and maternal antenatal depression was evaluated using the Edinburgh Postnatal Depression Scale. Baseline characteristics, clinical information, and associated factors were also included in the questionnaire. Analyses were conducted using a binomial logistic regression model with Edinburgh Postnatal Depression Scale positivity (maternal antenatal depression) as the dependent variable. Having "PMDD" (odds ratio: 3.54 [95% confidence interval: 1.26-9.93], p = 0.02) and "PMS" (odds ratio 2.31 [1.10-4.87], p = 0.03) on the PMDD rating scale were significantly associated with maternal antenatal depression. Therefore, our results suggest that screening for a history of PMS or PMDD during the early antepartum interview may aid mental health care and prevent perinatal depression during the early stages of pregnancy.

Patterns of attentional bias in antenatal depression: an eye-tracking study

Introduction

One of the most common mental disorders in the perinatal period is depression, which is associated with impaired emotional functioning due to alterations in different cognitive aspects including thought and facial emotion recognition. These functional impairment may affect emerging maternal sensitivity and have lasting consequences for the dyadic relationship. The current study aimed to investigate the impact of depressive symptoms on the attention bias of infant stimuli during pregnancy.

Methods

Eighty-six pregnant women completed the Edinburgh Postnatal Depression Scale and an eye-tracking task comprising infant-related emotion images. All participants showed biased attention to infant-related images.

Results

First, compared to healthy pregnant women, pregnant women with depression symptoms initially directed their attention to infant-related stimuli more quickly (F (1, 84) = 6.175, p = 0.015, η2 = 0.068). Second, the two groups of pregnant women paid attention to the positive infant stimuli faster than the neutral infant stimuli, and the first fixation latency bias score was significantly smaller than that of the infant-related negative stimulus (p = 0.007). Third, compared with the neutral stimulus, the non-depression group showed a longer first gaze duration to the negative stimulus of infants (p = 0.019), while the depressive symptoms group did not show this difference.

Conclusion

We speculate that structural and functional changes in affective motivation and cognitive-attention brain areas may induce these attentional bias patterns. These results provide suggestions for the implementation of clinical intervention programs to correct the attention bias of antenatal depressed women.

Depression and diet-related distress among Japanese women with gestational diabetes mellitus

Although the association between gestational diabetes mellitus (GDM) and maternal postpartum depression has been reported, the association between these two factors during pregnancy has not been sufficiently examined. We compared pregnant women with and without GDM to clarify the association and examined factors related to depression in pregnant women with GDM. Questionnaires were administered longitudinally to pregnant Japanese women in the third trimester and at 2 and 4 weeks postpartum. One hundred and five and 108 pregnant women with and without GDM, respectively, were included in the study. Of the 105 women with GDM, 20 (19.0%) reported being depressed during pregnancy, which was significantly higher than that among those without GDM (9.3%). Binomial logistic regression analysis revealed that depression was significantly positively associated with diet-related distress and negatively associated with social support among women with GDM. Diet-related distress and social support are important factors in managing depression in pregnant women with GDM.

Suicidal ideation and depressive symptoms in an urban post-partum maternity setting: a retrospective cohort study

BACKGROUND

Fifteen percent of women worldwide experience depression in the perinatal period. Suicide is now one of the leading causes of maternal mortality in developed countries. Internationally, many healthcare systems screen post-natal women for depressive symptoms and suicidal ideation to facilitate early assessment and intervention. To our knowledge, no Irish data exists on the prevalence of suicidal ideation in this cohort.

AIMS

To evaluate the prevalence of suicidal ideation and depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS) in post-natal women attending a large Dublin maternity hospital.

METHODS

A retrospective cohort study was conducted. Women were randomly selected by delivery date over a 6 month period. Demographic and medical information was collected from their booking visit and discharge summary data. EPDS results at discharge post-partum were examined.

RESULTS

Data was collected on 643 women. Post-partum, 19 women (3.4%) had experienced suicidal ideation in the previous 7 days. Just over half of these women also had high EPDS scores (>12). Overall, 29 women (5.2%) screened positive for depression (EPDS score > 12).

CONCLUSIONS

The rate of suicidal ideation is in line with the published international data and emphasises the need for all clinicians to inquire about such thoughts. Training of midwifery and obstetric staff is required. Maternity units should have a policy on the management of suicidal ideation and risk. The prevalence of depressive symptoms post-partum was comparatively low in our study. This could suggest that antenatal screening and early intervention, which are integral parts of the perinatal mental health service, are effective. However, due to limitations of the study, it could also reflect an under-representation of depressive symptom burden in this cohort.

Validation of the culturally adapted Edinburgh postpartum depression scale among east Asian, southeast Asian and south Asian populations: A scoping review

The Edinburgh Postnatal Depression Scale (EPDS) is a widely used self-report instrument to screen for postpartum depression (PPD). Assessing the relevance of the EPDS as a screening tool for minority ethnic populations is pertinent for ensuring culturally appropriate care. This scoping review aimed to explore what is known about the cultural adaptations of the EPDS in antepartum and postpartum mothers and fathers in East Asian, Southeast Asian and South Asian populations, and to what extent these adaptations are able to accurately screen for postpartum depression symptoms among these cultural groups. The scoping review was guided by the PRISMA-ScR checklist. The search strategy included databases of MEDLINE, PsycINFO, EMBASE, CINAHL and Grey literature. Included studies were primary articles published in English language peer-reviewed journals that investigated the validation or cultural adaptation of the EPDS in mothers who were pregnant and/or had recently given birth, or fathers who were new parents, and were limited to the following cultural groups, whether living locally or abroad in a foreign country: East Asian, Southeast Asian or South Asian populations. Thirty-six of 2469 studies met criteria for inclusion. Twenty-one of 36 studies utilizing a culturally validated EPDS demonstrated a cut-off score lower than the original recommended cut-off. Important themes identified included the Role of Culture, Somatization of PPD, Method of Interview, and contrasting performance compared to other scales used to assess depression and/or anxiety. Accessibility to translated and validated EPDS and mindfulness of ethnically relevant EPDS cut-off scores are critical when using this tool among minority ethnic populations.

Prevalence and associated factors of probable depression amongst pregnant and parenting young females: a comparison of adolescents and young adults in rural South Africa

Background

Pregnant teenagers have been reported to have an increased likelihood of experiencing depression than their non-pregnant peers. There is little research on the risk factors for depression in rural Black adolescents and young adults, especially after the Covid-19 pandemic. Therefore, the current study aimed to identify the prevalence of probable depression and associated factors amongst pregnant and parenting young females.

Method

The study was a cross-sectional design, consisting of 362 pregnant and parenting adolescents and young adults aged 14-22. The study used the Edinburgh Postnatal Depression Scale (EPDS) to measure probable depression. Data were analyzed using Statistical Package for Social Sciences SPSS, version 27.0.

Results

The study found that the overall prevalence of probable depression was 42.8%. The study also found a relationship between alcohol consumption, lack of financial support, unplanned pregnancy, and probable depression in pregnant and parenting adolescents. The prevalence of unplanned pregnancy in the present study was 81.8%.

Conclusion

Furthermore, the present study indicated that participants from low socio-economic status families and those who were HIV positive were at a greater risk of depression in both groups. Therefore, we recommend that measures be put in place for early detection and treatment of depression and that social support be given to adolescent mothers.

The diagnostic accuracy of the Edinburgh Postnatal Depression Scale without the self-harm item

The Edinburgh Postnatal Depression Scale (EPDS) is the most commonly used screening tool for perinatal depression. However, the 10th item of the EPDS intended to evaluate suicide ideation does not accurately capture suicide ideation and may cause psychological distress. Whereas endorsement of the strongest agreement "yes, quite often" on this item may be associated with suicide ideation, the response on this frequency is perfectly predicted by the EPDS full score. The discard of this item, therefore, is preferred. In the current study, using data from a nation-wide internet survey conducted in Japanese postpartum (n = 5688) and pregnant women (n = 1639), we show that the EPDS-9 without the 10th item correlates perfectly with the full EPDS or EPDS-10. Furthermore, the EPDS-9 and EPDS-10 have equivalent performance in differentiating participants' self-reported depression diagnosis as well as Kessler Psychological Distress Scale (K6)-based screening of depression. Lastly, at the cutoff of 9, the EPDS-9 performs well in predicting participants' response on the 10th item of EPDS; specifically, the sensitivity of differentiating frequent thoughts of self-harm is 0.968 and 1 in postpartum and pregnant women, respectively. Therefore, the EPDS-9 performs equivalently to EPDS-10 and can be considered to replace EPDS-10 in future use.

Effectiveness of mHealth consultation services for preventing postpartum depressive symptoms: a randomized clinical trial

BACKGROUND

Although many conventional healthcare services to prevent postpartum depression are provided face-to-face, physical and psychosocial barriers remain. These barriers may be overcome by using mobile health services (mHealth). To examine the effectiveness of mHealth professional consultation services in preventing postpartum depressive symptoms in real-world settings, we conducted this randomized controlled trial in Japan, where universal free face-to-face perinatal care is available.

METHODS

This study included 734 pregnant women living in Yokohama city who could communicate in Japanese, recruited at public offices and childcare support facilities. The participants were randomized to the mHealth group (intervention, n = 365), where they could use a free app-based mHealth consultation service with gynecologists/obstetricians, pediatricians, and midwives whenever and as many times as they wanted between 6 p.m. and 10 p.m. on weekdays throughout their pregnancy and postpartum periods (funded by the City of Yokohama government) or the usual care group (control, n = 369). The primary outcome was the risk of elevated postpartum depressive symptoms, defined as Edinburgh Postnatal Depression Scale score ≥ 9. Secondary outcomes were self-efficacy, loneliness, perceived barriers to healthcare access, number of clinic visits, and ambulance usage. All outcomes were collected three months post-delivery. We also conducted subgroup analyses assessing the differences in the treatment effect by sociodemographic status.

RESULTS

Most women completed all questionnaires (n = 639 of 734, response rate: 87%). The mean baseline age was 32.9 ± 4.2 years, and 62% were primipara. Three months post-delivery, women in the mHealth group had a lower risk of elevated postpartum depressive symptoms (47/310 [15.2%]) compared to the usual care group (75/329 [22.8%], risk ratio: 0.67 [95% confidence interval: 0.48-0.93]). Compared with the usual care group, women in the mHealth group had higher self-efficacy, less loneliness, and fewer perceived barriers to healthcare access. No differences were observed in the frequency of clinic visits or ambulance usage. Furthermore, in the subgroup analyses, we did not find differences in the treatment effect by sociodemographic status.

CONCLUSIONS

Local government-funded mHealth consultation services have a preventive effect on postpartum depressive symptoms, removing physical and psychological barriers to healthcare access in real-world settings.

Development and validation of the Japanese version of EPDS-P for indirect screening of paternal perinatal depression based on maternal reporting: Protocol for a prospective longitudinal observational study

AIMS

The main purpose of this study is to develop an indirect screening system for paternal perinatal depression based on the female partner's assessment in the Japanese population. The Japanese version of the Edinburgh Postnatal Depression Scale-Partner (EPDS-P) will be used as the indirect screening tool, and its accuracy will be studied in this longitudinal prospective observational study.

METHODS

Public health nurses and midwives at the participating community health center are currently inviting couples to participate, and are distributing self-rating scales to the participants. The primary evaluation scales being used in this study are the Japanese versions of the Center for Epidemiologic Studies Depression Scale (CES-D) and the Japanese version of the EPDS-P which evaluates paternal perinatal depression by women. We will evaluate EPDS-P performance against CES-D, including accuracy, sensitivity, specificity, and correlations.

RESULTS AND CONCLUSIONS

Perinatal depression is a mental illness that occurs between pregnancy and postpartum within the 12 months, and it is known to increase the risk of adversely impacting on child development. Men may also experience a psychosocial crisis during their partners' perinatal period. Although it was recently reported that the EPDS-P can indirectly detect paternal perinatal depression, there is, as yet, insufficient evidence of this because the previous studies had relatively small sample sizes and were limited to cross-sectional studies in the postpartum period. The development of a screening system for paternal perinatal depression using the EPDS-P will lead to increased awareness of the disease and provide an opportunity to establish a family-based support system in Japan.

Comparison of response options and actual symptom frequency in the Japanese version of the Edinburgh Postnatal Depression Scale in women in early pregnancy and non-pregnant women

BACKGROUND

The positive predictive rate of the Japanese version of the Edinburgh Postnatal Depression Scale (EPDS) is lower than those of other versions. This study aimed to confirm whether the EPDS Japanese version reflects actual symptom frequency and to examine the possibility of improving the positive predictive rate.

METHODS

This is a methodological study aimed at improving the positive predictive value of EPDS. The participants were 63 non-pregnant and 382 pregnant women. They answered the 10 questions of the Japanese version of the EPDS and reported the specific number of days as the frequency. The EPDS score (EPDS-S) and the frequency score (FREQ-S) were calculated for three factors of emotion: anhedonia, anxiety, and depression.

RESULTS

The positive rates of the EPDS-S and FREQ-S in pregnant women were 6% and 8%, respectively, which were lower than those in non-pregnant women (17%). On comparing the EPDS-S with the FREQ-S, a significant underestimation of frequency was observed in approximately 3% of pregnant women. The FREQ-S showed better internal consistency than the EPDS-S. Among the factors of emotion, women tended to rate anhedonia lower in the EPDS-S than in the frequency scale.

CONCLUSION

Pregnant women tended to report a lower frequency on the Japanese version of the EPDS than their actual symptom frequency, which was especially true for those with a desire to self-harm. The combined use of the FREQ-S and EPDS-S can prevent underestimation and help improve the detection rate of depression.

Correlation between psychiatric impact of COVID-19 during pregnancy and fetal outcomes in Egyptian women

The prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) was examined in 238 pregnant women with (n = 146) and without (n = 92) coronavirus disease 2019 (COVID-19) using the State-Trait Anxiety Inventory (STAI), Edinburgh Postnatal Depression Scale (EPDS), and PTSD Checklist for DSM-5 (PCL-5). Fetal outcomes in the same groups were evaluated using the Apgar score. Anxiety and depression scores were significantly higher in women with COVID-19 but PTSD scores were similar in both groups. Infection with COVID-19 was associated with a higher number of fetal deaths or an Apgar score <7. During the COVID-19 pandemic, approximately 46.6% of pregnant women had depression, 5.5% had PTSD, 64.3% had state anxiety, and 60.9% had trait anxiety. Except for PTSD, psychiatric problems and poor fetal outcomes were higher in women with COVID-19 than in those without COVID-19. Lastly, women with COVID-19 were more prone to have a fetus who died or had an Apgar score of <7.

Relationship between Antenatal Mental Health and Facial Emotion Recognition Bias for Children’s Faces among Pregnant Women

The importance of identification of facial emotion recognition (FER) bias for a child’s face has been reinforced from the perspective of risk screening for future peripartum mental health problems. We attempted to clarify the relationship of FER bias for children’s faces with antenatal depression and bonding failure among pregnant women, taking into consideration their broad social cognitive abilities and experience in child raising. This study had a cross-sectional design, and participants were women in their second trimester of pregnancy. Seventy-two participants were assessed by the Edinburgh Postnatal Depression Scale (EPDS), the Mother-to-Infant Bonding Questionnaire (MIBQ), and a series of social cognitive tests. FER bias for a child’s face was assessed by Baby Cue Cards (BCC), and a larger number of disengagement responses suggest greater sensitivity to a child’s disengagement facial expressions. In a regression analysis conducted using EPDS as the dependent variable, a larger number of disengagement responses to the BCC (β = 0.365, p = 0.001) and the primipara status (β = −0.263, p = 0.016) were found to significantly contribute to antenatal depressive symptoms. Also, more disengagement responses to the BCC also significantly contributed to bonding failure as measured by the MIBQ (β = 0.234, p = 0.048). Maternal sensitivity to the child’s disengagement cues was associated with antenatal depressive symptoms and bonding failure more than the other social cognitive variables. The effects of FER bias on postpartum mental health and abusive behavior needs to be clarified by further longitudinal studies.

Impact of health literacy on anxiety and depressive symptoms in pregnant women in Japan during the COVID-19 pandemic

To investigate the relationships between communicative and critical health literacy (CCHL) and anxiety and depressive symptoms (ADs) in pregnant women during the coronavirus disease 2019 (COVID-19) pandemic. A cross-sectional study was conducted and 5466 pregnant women responded in Japan in September 2020. A Kessler 6 scale (K6) score ≥ 10, an Edinburgh Postnatal Depression Scale (EPDS) score ≥ 13, and four CCHL groups were analyzed using a logistic regression model and trend test. The proportions of pregnant women with a K6 score ≥ 10 and EPDS score ≥ 13 were 13.5 and 15.4%, respectively. In comparisons with the low CCHL group, the adjusted odds ratio (95% CI) for anxiety symptoms was 0.770 (0.604–0.982) in the high CCHL group, while those for depressive symptoms were 0.777 (0.639–0.946), 0.665 (0.537–0.824), and 0.666 (0.529–0.838) in the lower, higher, and high CCHL groups (all p < 0.05), respectively, after adjustments for potential confounding factors, such as age, weeks of gestation, complications, history, number of children, marital status, education, employment, and income. Higher CCHL was associated with significantly lower adjusted odds ratios for anxiety (p for trend = 0.019) and depressive symptoms (p for trend < 0.001). These results suggest a relationship between CCHL and ADs in pregnant women during the COVID-19 pandemic.

Antenatal screening timeline and cutoff scores of the Edinburgh Postnatal Depression Scale for predicting postpartum depressive symptoms in healthy women: a prospective cohort study

Background

It is worthwhile to identify women at risk of developing postpartum depression during pregnancy. This study aimed to determine the optimal time and cutoff score for antenatal screening for prediction of postpartum depressive symptoms (PDS) using the Edinburgh Postnatal Depression Scale (EPDS) and to identify risk factors for PDS.

Methods

The target population was healthy pregnant women receiving antenatal care at a university hospital in Tokyo, Japan. During the first, second, and third trimesters, 3–4 days postpartum, and one month postpartum, they were asked to take the Japanese version of the EPDS questionnaire. The primary outcome of the study was PDS, defined as an EPDS score ≥ 9 at one month postpartum. The area under the receiver operating characteristics curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of EPDS scores at each antenatal screening time were calculated.

Results

From 139 pregnant women, 129 were successfully followed up throughout the study. The number of women with an EPDS score ≥ 9 during the first, second, and third trimesters, 3–4 days postpartum, and one month postpartum were 6/126 (4.8%), 9/124 (7.3%), 5/117 (4.3%), 17/123 (13.8%), and 15/123 (12.2%), respectively. Screening during the second trimester had the highest AUC to predict PDS (0.89) among antenatal screenings. The optimal EPDS cutoff score during the second trimester was 4/5 (sensitivity: 85.7%; specificity: 77.1%; PPV: 33.3%; NPV: 97.6%). An EPDS score ≥ 5 during the second trimester (adjusted odds ratio [aOR]: 15.9; 95% confidence interval [95%CI]: 3.2–78.1) and a family history of mental illness (aOR: 4.5; 95%CI: 1.2–17.5) were significantly associated with PDS.

Conclusions

Our study suggests that the EPDS score at the second trimester with the cutoff value of 4/5 may be adequate for initial screening for prediction of PDS. Women with an EPDS score ≥ 5 at the second trimester require more elaborate follow-up.

The COVID-19 Pandemic and Mental Well-Being of Pregnant Women in Japan: Need for Economic and Social Policy Interventions

OBJECTIVE

This study explores the mental well-being of pregnant women in Japan during the coronavirus disease (COVID-19) pandemic.

METHODS

We collected 1777 responses from pregnant women through an online survey. Using the Japanese version of the Edinburgh Postnatal Depression Scale (EPDS), we calculated the percentage of pregnant women above the cutoff (≥ 13), and the factor scores of anhedonia, anxiety, and depression. Regression analyses were performed to identify factors and socioeconomic characteristics correlated with depressive symptoms.

RESULTS

The point prevalence of pregnant women with an EPDS score of ≥ 13 was 17%. The mean scores were 0.73, 3.68, and 1.82 for anhedonia, anxiety, and depression, respectively. The probability of becoming above the cutoff score positively correlated with the cancellation of planned informal support, higher perceived risk for infection of COVID-19, difficulties in household finances, and lack of social support. Moreover, being younger, less wealthy, unemployed, and without a partner showed a significantly higher possibility of having a score above the cutoff.

CONCLUSIONS

The present study found a high percentage of pregnant women with depressive symptoms. Notably, COVID-19-related variables, including perceived risk for the infection, fear of decreasing economic wealth, and social support, were significantly associated with depressive symptoms.

Antenatal screening of depressive and manic symptoms in south Brazilian childbearing women: A transversal study in advance of the pandemic scenario

Background

The diagnosis of mood disorders (MD) during pregnancy is challenging and may bring negative consequences to the maternal-fetal binomial. The long waitlist for specialized psychiatric evaluation in Brazil contributes to the treatment omission. Almost 20.0% of women treated with antidepressants have a positive screening for bipolar disorder. Therefore, it has been recommended the investigation of depressive and bipolar disorder during prenatal care. Unfortunately, the screening for mood disorders is not a reality in Brazil and many childbearing women remain undiagnosed. The objective of this study is to observe the frequency of MD and the effectiveness of screening scales for routine use by health professionals during prenatal care in high-risk pregnancies.

Methodology/Principal findings

This cross-sectional study included 61 childbearing women in their second trimester who were interviewed using the Edinburgh Postnatal Depression Scale (EPDS) and the Mood Disorder Questionnaire (MDQ). The cut-off point was EPDS ≥ 13 and MDQ ≥ 7 and the SCID-5 was the gold standard diagnosis. MD were diagnosed in 24.6% of the high-risk pregnancies. EDPS was positive in 19.7% and the frequency of major depression was 8.2%. 16.4% of the childbearing women were diagnosed with bipolar disorder, while MDQ was positive in 36.1%. 11.5% of the women had EPDS and MDQ positive. EPDS sensitivity was 80.0% and specificity 92.1%, whereas MDQ presented a sensitivity of 70.0% and specificity of 70.6%.

Conclusion/Significance

There is a high prevalence of MD in high-risk pregnancies. The routine use of EPDS simultaneously to MDQ during antenatal care is effective and plays an important role in early diagnosis, counselling, and promotion of perinatal mental health.

Awareness of paternal age effect disorders among Japanese pregnant women: implications for prenatal genetic counseling for advanced paternal age

The increasing prevalence of advanced paternal age (APA) has mirrored the rise in maternal age. APA is associated with an increased risk of de novo pathogenic single-nucleotide variants, but this topic has been much less frequently discussed than advanced maternal age (AMA). To explore the awareness of pregnant women regarding paternal age effect (PAE) disorders, a self-administered questionnaire survey was conducted for pregnant women at their first prenatal visit before 17 weeks of gestation. A total of 120 valid respondents (95.2%) were included in the analyses. Of these, 63.3% of pregnant women were aware of PAE disorders. This was markedly lower than the 90.8% recognition of maternal age effect (MAE) disorders. One-third of women with awareness of MAE disorders were not aware of PAE disorders. Pregnant women who were parous, older than their male partners, with knowledge of prenatal testing prior to this pregnancy, and with experience of prenatal testing in a prior pregnancy were significantly more aware of PAE disorders than others. Awareness of PAE disorders was not associated with undergoing prenatal testing during the present pregnancy. Our results show that the prevalence of pregnant women's awareness of PAE disorders was lower than that of MAE disorders. The current study served as a preliminary baseline of information about pregnant women's awareness of PAE disorders. With the introduction of non-invasive prenatal testing, which has the potential to identify PAE disorders, these findings will help the development of a framework for comprehensive prenatal genetic counseling for APA pregnancies.

Do depressive symptoms among pregnant women assisted in Primary Health Care services increase the risk of prematurity and low birth weight?

Objective:

to investigate associations between depressive symptoms during pregnancy, low birth weight, and prematurity among women with low-risk pregnancies assisted in public Primary Health Care services.

Method:

prospective cohort with 193 pregnant women, using the Edinburgh Postnatal Depression Scale, telephone interviews, and medical records available in the health services. Associations of interest were obtained using the Cox regression model.

Results:

the participants were aged 24.9 years old (median) and had 11 years of schooling (median); 82.4% lived with their partners, and gestational age at the birth was 39 weeks (median). Twenty-five percent of the participants scored ≥13 on the Edinburgh scale. Depressive symptoms did not appear associated with low birth weight (RR=2.06; CI95%=0.56-7.61) or prematurity (RR=0.86; CI95%=0.24-3.09) in the adjusted analysis. However, premature labor increased the risk of low birth weight (RR=4.81; CI95%=1.01-23.0) and prematurity (RR=7.70; CI95%=2.50-23.7). Additionally, each week added to gestational age decreased the risk of low birth weight (RR=0.76; CI95%=0.61-0.95).

Conclusion:

the presence of depressive symptoms among women with low-risk pregnancies was not associated with low birth weight or prematurity.

Social and Demographic Factors Associated with Postnatal Depression Symptoms among HIV-Positive Women in Primary Healthcare Facilities, South Africa

Background: Mothers living with HIV are at risk for mental health problems, which may have a negative impact on the management of their HIV condition and care of their children. Although South Africa has a high prevalence of HIV, there is a dearth of studies on sociodemographic predictors of postnatal depression (PND) among HIV-positive women in South Africa, even in KwaZulu Natal, a province with the highest prevalence of HIV in the country. Objective: The objective of the study was to determine sociodemographic factors associated with the prevalence of postnatal depression symptoms among a sample of HIV-positive women attending health services from primary healthcare facilities in Umhlathuze District, KwaZulu Natal. Methods: A quantitative cross-sectional survey was used to collect data from 386 HIV-positive women who had infants aged between 1 and 12 weeks. The Edinburgh Postnatal Depression Scale (EPNDS), to which sociodemographic questions were added, was used to collect data. Results: The prevalence of PND symptoms among this sample of 386 HIV-positive women was 42.5%. The age of the mothers ranged from 16 to 42 years, with a mean of 29 years. The majority of the mothers were single or never married (85.5%; n = 330), living in a rural setting (81.9%; n = 316%), with a household income of less than R 2000 (estimated 125 USD) per month (64.9%; n = 120). The government child support grant was the main source of income for most of the mothers (53%; n = 183). PND symptoms were significantly associated with the participant’s partner having other sexual partners (p-value < 0.001), adverse life events (p-value = 0.001), low monthly income (p-value = 0.015), and being financially dependent on others (p-value = 0.023). Conclusion: The prevalence of PND symptoms among the sample is high, with a number of social and demographic factors found to be significantly associated with PND. This requires the consideration of sociodemographic information in the overall management of both HIV and postnatal depression. Addressing the impact of these factors can positively influence the health outcomes of both the mother and the baby.

Psychosocial factors associated with postpartum psychological distress during the Covid-19 pandemic: a cross-sectional study

BACKGROUND

Trauma, natural and man-made catastrophic events can be predictors of postpartum psychological distress. In a public health response due to coronavirus disease 2019 outbreak, the Italian government imposed a lockdown from March 9 to May 3. This extraordinary situation may have been challenging for maternal psychological health. The aim of this study was to investigate the prevalence of depressive and post-traumatic stress symptoms in women giving birth during the Covid-19 pandemic and its associations with quarantine measures, obstetrical factors, and relational attachment style.

METHODS

Women who gave birth in a high-volume obstetric/gynaecological medical centre located in an epidemic area during the Covid-19 pandemic (March 8 to June 15) were asked to complete an online survey about their childbirth experience and the perceived effect of the pandemic. The Edinburgh Postnatal Depression Scale (EPDS), the Impact of Event Scale-Revised (IES-R), and the Relationship Questionnaire (RQ) were administered to assess levels of postpartum depressive and post-traumatic stress symptoms (PTSS) and relational style of attachment, respectively. Multivariate analysis was applied to identify associations between quarantine measures, childbirth experience, attachment style, and EPDS and IES-R scores.

RESULTS

The survey was completed by 163 women (response rate 60.8%). The prevalence of depressive symptoms was 44.2% (EPDS cut-off score ≥ 11) and the PTSS rate was 42.9% (IES-R cut-off score ≥ 24). Dismissive and fearful avoidant attachment styles were significantly associated with the risk of depression and PTSS, respectively. Perceived pain during birth was a risk factor for postpartum depression. Perceived support provided by healthcare staff was a protective factor against depression and PTSS. Another protective factor against PTSS was quiet on the ward due to the absence of hospital visitors.

CONCLUSION

This study reports a high prevalence of postpartum depressive and PTSS in women who gave birth during the Covid-19 pandemic. Postnatal psychological distress seemed to be associated more with the prenatal experience and other individual factors than with the pandemic hospital restrictions. Early detection during pregnancy of an insecure attachment style is fundamental to provide targeted preventive and therapeutic psychological interventions.

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

INTRODUCTION

Perinatal depression is a widely discussed mental illness that occurs not only in women, but also in men. A previous international meta-analysis of the prevalence of paternal perinatal depression suggested that cross-cultural variables or socioeconomic environment may influence paternal depression. However, it is not clear that these data are general enough to apply to Japanese men, and there are few review articles about perinatal depression among this demographic. The purpose of our study is to provide a reliable estimate of the prevalence of perinatal depression among Japanese men.

METHOD

We searched two databases, PubMed and ICHUSHI, to identify studies with data on the prevalence of prenatal or postpartum depression among Japanese men. Data were extracted from reports published from January 1994 to June 2018. The period prevalence of paternal perinatal depression among Japanese men was investigated. A subgroup analysis of gender differences in perinatal depression was also performed.

RESULTS

We reviewed 1,379 abstracts, retrieved 33 articles and ultimately included 15 studies. The period prevalence of paternal prenatal depression in men was 8.5% (95% CI 3.3-20.3%). Moreover, the period prevalence of postpartum depression in men was 9.7% (95% CI 7.4-12.8%) within the first month, 8.6% (95% CI 5.5-13.3%) in postpartum months 1-3, 13.2% (95% CI 11.6-15.0%) in postpartum months 3-6 and 8.2% (95% CI 1.3-38.0%) in postpartum months 6-12. We also found that the prevalence of prenatal depression was significantly lower in men than in women. However, the prevalence of postpartum depression was not significantly different between men and women.

CONCLUSIONS

The prevalence of perinatal depression among Japanese men peaked at 3-6 months after birth, and its overall prevalence was approximately 10%. These results were similar to those of an international meta-analysis on perinatal depression. Notably, we found that the prevalence of postpartum depression was as high in men as it was in women. Therefore, it is suggested that healthcare workers should be more watchful for paternal perinatal depression in the postpartum period than in the prenatal period.

Perinatal depression and anxiety of primipara is higher than that of multipara in Japanese women

The proportion of women who experience a depressive state after delivery differs between primiparas and multiparas, so it is important to clarify the different factors related to depression between the two groups. In this study, we confirmed the differences in depressive states, the perinatal period, and social support between primiparas and multiparas, and clarified their characteristics. Data were extracted from a prospective cohort questionnaire survey conducted on pregnant women in Japan that included sociodemographic questions, the Edinburgh Postnatal Depression Scale, and the Japanese version of the Social Support Questionnaire. We carried out the chi-square test, Student's t-test, and analysis of covariance to compare responses between primiparas and multiparas. A total of 1138 primiparas and 380 multiparas provided valid responses. We found that primiparas had higher rates of experiencing maternity blues and postpartum depression than multiparas. We also found that primiparas had higher anxiety scores than multiparas. Primiparas with postpartum depression perceived a lower number of persons available to provide social support than primiparas without postpartum depression. These findings suggest that it is important to provide pregnant women, especially for primiparas, with information that allows them to increase the number of people who can provide them with support.

Identification of clinical and psychosocial characteristics associated with perinatal depression in the south Indian population

BACKGROUND

Longitudinal perinatal depression (PND) data is sparsely available in the Indian population. We have employed Edinburgh Postnatal Depression Scale (EPDS) to assess the prevalence and identify characteristics associated with PND in the south Indian population. PND was assessed longitudinally using EPDS scores with traditional cut-off approach as well as a novel method of latent class mixture modeling (LCMM). The LCMM method, to the best of our knowledge, has been used for the first time in the Indian population.

METHODS

Three hundred and forty seven women, predominantly from economically-weaker sections of rural and urban South India were longitudinally assessed for antenatal depression (AD) and postnatal depression (PD) using EPDS cutoff-scores ≥13 and ≥10, respectively. Uni/multivariable analyses were used to identify PND associated characteristics. LCMM was then implemented, followed by risk characteristics identification.

RESULTS

PND prevalence from traditional approach was 24.50 % (12.68 % AD; 18.16% PD). Characteristics associated with PND were urban-site and recent adverse life events. Irregular menstrual history and chronic health issues were associated with AD and PD, respectively. Three distinct PND trajectories were observed from LCMM-analysis: low-risk (76.08%), medium-risk (19.89%) and high-risk (4.04%). Urban-site, recent adverse life events, irregular menstrual history and pregnancy complications were associated with medium-risk/high-risk trajectories.

LIMITATIONS

EPDS is a screening tool and not a diagnostic tool for depression. Since the study population included women from economically-weaker sections, the results need verification in other socio-economic groups.

CONCLUSIONS

Both the traditional cut-off-based approach and LCMM provided very similar conclusions regarding the prevalence of PND and characteristics associated with it. Higher PND prevalence was observed in urban women compared to rural women. In low-income countries, identifying risk characteristics associated with PND is a critical component in designing prevention strategies for PND related conditions because of the limited access to mental health resources.

Maternal and neonatal outcomes associated with restless legs syndrome in pregnancy: A systematic review

Restless legs syndrome (RLS) affects one in five pregnant women. This review aims to synthesise evidence regarding gestational RLS and its consequences on pregnant women and neonates. Search of Embase, MEDLINE, PsycINFO, Maternity and Infant Care and Scopus was conducted in July 2018 using MeSH headings and keywords for 'restless legs syndrome' and 'pregnancy' or 'birth'. Our search identified 16 eligible studies from 12 countries published between 2004 and 2018 concerning gestational RLS and one or more maternal, delivery or neonatal outcomes. The most consistent associations were observed between gestational RLS and increased risks of gestational hypertension, pre-eclampsia, and peripartum depression. There were mixed findings for caesarean delivery, preterm birth and low birth weight, with the majority reporting no association with gestational RLS. Gestational RLS was not associated with postpartum haemorrhage, gestational diabetes, fetal distress, or low Apgar scores. Future research is needed to investigate whether effective treatment of RLS can mitigate these potential harms. Validated methods for diagnosing RLS in pregnancy would support research in this growing field.

Validation and factor structure of the Japanese version of the inventory to diagnose depression, lifetime version for pregnant women

Introduction

A history of major depressive disorder before pregnancy is one risk factor for peripartum depression. Therefore, the purpose of the present study was to examine the validation and factor structure of the Japanese version of the Inventory to Diagnose Depression, Lifetime version (IDDL) for pregnant women.

Methods

The study participants were 556 pregnant women. Factor analysis was performed to identify the factor structure, construct validity was examined based on the results of the factor analysis, and reliability was examined using Cronbach’s α coefficient.

Results

Based on the results of the factor analysis of the IDDL, a bifactor model composed of a single general dimension along with the following five factors was extracted: (1) depression, anxiety, and irritability (items 1, 2, 8–10, and 19–21); (2) retardation, decreased concentration, indecisiveness, and insomnia (items 4, 11, 12, and 17); (3) decrease in appetite/significant weight loss (items 13 and 14); (4) increase in appetite/significant weight gain (items 15 and 16); and (5) diminished interest, pleasure, and libido (items 5–7). Cronbach’s α coefficients for these five factors were as follows: 0.910, 0.815, 0.780, 0.683, and 0.803, respectively.

Conclusions

The reliability, construct validity, and factor structure of the Japanese version of the IDDL were confirmed in pregnant women.

Anxiety, Prenatal Attachment, and Depressive Symptoms in Women with Diabetes in Pregnancy

The purpose of this study was to evaluate the relationship between anxiety, prenatal attachment, and depressive symptoms among women with diabetes in pregnancy. Participants were 131 consecutive pregnant women between the ages of 20 and 45 with a diagnosis of gestational or pregestational type 1 or type 2 diabetes. Data on previous psychiatric symptoms were obtained from the Anamnestic and Social Questionnaire and the Mini-International Neuropsychiatric Interview (MINI). Information on prenatal attachment was collected using The Prenatal Attachment Inventory (PAI), and The Edinburgh Postnatal Depression Scale (EPDS) assessed depressive symptoms in the third trimester of pregnancy (at a mean of 25 weeks). Results demonstrated that in women affected by diabetes in pregnancy, two facets of prenatal attachment (anticipation, interaction) were negatively correlated with depressive symptoms, and a history of anxiety, assessed with the MINI, moderated the relation between the prenatal attachment interaction factor and depressive symptoms during pregnancy.

Father Involvement in Infant Parenting in an Ethnically Diverse Community Sample: Predicting Paternal Depressive Symptoms

Early paternal involvement in infant care is beneficial to child and maternal health, and possibly for paternal mental health. The purpose of the present study was to examine the relationship between fathers' involvement in early infant parenting and their depressive symptoms during the infant's first year in a sample of 881 low-income Black, Hispanic, and White fathers recruited from five sites in the United States (urban, mixed urban/suburban, rural). Home interviews at 1 month after birth assessed three concepts based on prior research and community input: (1) time spent with the infant, (2) parenting self-efficacy, (3) material support for the baby. Paternal depressive symptoms at 1, 6, and 12 months after the birth of a child were assessed with the Edinburgh Postpartum Depression Scale. Generalized estimating equations tested whether the three indicators of father involvement at 1 month after birth predicted lower subsequent paternal depressive symptoms controlling for social and demographic variables. For fathers, greater time spent with the infant, parenting self-efficacy, and material support were all significantly associated with lower paternal depressive symptoms during the first year. When risk of depression (scores > 9) was examined, only parenting self-efficacy among fathers was associated with higher likelihood of clinical depression. Findings have implications for future research on mechanisms linking paternal involvement and paternal mental health, and for possible paid paternal leave policies in the future.

Impact of intention and feeling toward being pregnant on postpartum depression: the Japan Environment and Children's Study (JECS)

Pregnancy intention is reported to be associated with the risk of postpartum depression (PPD), but the impact of feelings toward being pregnant on PPD is unknown. We aimed to examine whether feelings toward being pregnant are associated with PPD at 1 month after childbirth. In our nationwide study between 2011 and 2014 in Japan, we used multivariate logistic regression analyses to examine the associations between pregnancy intention and feelings toward being pregnant with PPD [Edinburgh Postnatal Depression Scale (EPDS score > 9 or > 12)] among Japanese women. Among 92,431 women, 14.0 and 5.4% had PPD with EPDS scores > 9 and > 12, respectively. Compared with women who felt very happy to be pregnant, those whose pregnancy was unintended but happy, unintended and confused, those who felt troubled, and those who felt no emotion toward being pregnant had increased risks of PPD [multivariable odds ratios (95% confidence intervals (CIs)) = 1.17 (1.11-1.22), 1.39 (1.29-1.49), 1.74 (1.42-2.14), and 1.58 (1.22-2.02), respectively, for EPDS score > 9]. Those associations were more evident without antenatal possible mental illness (K6 score < 13). Women whose pregnancy was unintended should be regarded as targets for the early detection and prevention of PPD irrespective of whether they felt happy or confused.

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.

Psychometric properties of the Arabic version of EPDS and BDI-II as a screening tool for antenatal depression: evidence from Qatar

OBJECTIVES

The current study aimed to validate and determine the psychometric properties of the Arabic versions of the Beck Depression Inventory-II (BDI-II) and the Edinburgh Postnatal Depression Scale (EPDS) in Qatar.

DESIGN

A cross-sectional study design was employed.

SETTING

Antenatal care (ANC) clinics at nine primary healthcare centres.

PARTICIPANTS

Pregnant women (n=128) aged 15-46 years in different trimesters of pregnancy, attending the ANC clinics as well as capable of reading and writing in the Arabic language.

RESULTS

A total of 128 participants were enrolled. On conducting the receiver operating characteristic (ROC) analysis, the EPDS showed a larger area under the curve at 0.951 than the BDI-II tool (0.912). Using Youden's index, a score >13 on the EPDS (87% sensitivity, 90% specificity) and >19 on the BDI-II (96% sensitivity, 73% specificity) allowed for the greatest division between depressed and non-depressed participants.

CONCLUSION

To address the under-recognition of antenatal depression, physicians at primary healthcare centres in Qatar should be encouraged to utilise the EPDS to screen pregnant women seeking ANC services.

Retrospective follow-up analysis of the transcriptomic patterns of cytokines, cytokine receptors and chemokines at preconception and during pregnancy, in women with post-partum depression

Post-partum depression (PPD) occurs in approximately 20% of women usually early following child delivery. PPD represents an important unmet medical need as it is frequently underdiagnosed and, as the neurobiology of the disease is limitedly known, no pathogenic-tailored approach is available and only symptomatic medications are used. In the present study, we carried out a DNA microarray analysis to evaluate the fluctuation of cytokines, cytokine receptors and chemokines during the preconception period, the 1st and 3th trimester of pregnancy and the early post-partum period. The data demonstrated that, as compared to always-depressed patients and euthymic controls, women who developed PPD exhibited significant fluctuations in the levels of different cytokines and cytokine receptors, primarily related to tumor necrosis factor (TNF) and interleukin (IL)18. These data emphasize the role of the immune system in PPD. However, additional studies aimed at evaluating if and how these functional modifications of the immune system during pregnancy are related to the development of PPD warranted to confirm our findings.

Methylation analysis for postpartum depression: a case control study

BACKGROUND

Postpartum depression (PPD) is a major depressive disorder that occurs after childbirth. Objective diagnostic and predictive methods for PPD are important for early detection and appropriate intervention. DNA methylation has been recognized as a potential biomarker for major depressive disorder. In this study, we used methylation analysis and peripheral blood to search for biomarkers that could to lead to the development a predictive method for PPD.

METHODS

Study participants included 36 pregnant women (18 cases and 18 controls determined after childbirth). Genome-wide DNA methylation profiles were obtained by analysis with an Infinium Human Methylation 450BeadChip. The association of DNA methylation status at each DNA methylation site with PPD was assessed using linear regression analysis. We also conducted functional enrichment analysis of PPD using The Database for Annotation, Visualization and Integrated Discovery 6.8 to explore enriched functional-related gene groups for PPD.

RESULTS

In the analysis with postpartum depressed state as an independent variable, the difference in methylation frequency between the postpartum non-depressed group and the postpartum depressed group was small, and sites with genome-wide significant differences were not confirmed. After analysis by The Database for Annotation, Visualization and Integrated Discovery 6.8, we revealed four gene ontology terms, including axon guidance, related to postpartum depression.

CONCLUSIONS

These findings may help with the development of an objective predictive method for PPD.

Re-evaluation of the Edinburgh Postnatal Depression Scale as screening for post-partum depression in Iwate Prefecture, Japan

AIM

Although the Edinburgh Postnatal Depression Scale (EPDS) is widely used for screening for post-partum depression (PPD), screening time point and cut-off value in the current medical environment are not sufficiently examined. In this study, we examined appropriate timing and cut-off value of EPDS for the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders Fifth Edition.

METHODS

This study was a prospective cohort study of women who delivered at the Iwate Medical University Hospital from August 2016 to February 2019. The EPDS self-assessment was conducted at 4 days and at 1 month after delivery (4D-EPDS and 1M-EPDS), and the Center for Epidemiologic Studies-Depression scale (CES-D) self-assessment was conducted at 1 month after delivery (1M-CES-D) in eligible patients and the scores were tabulated. Participants were interviewed by a psychiatric specialist to identify PPD within 2 months after delivery. For each screening, a receiver operating characteristic analysis was performed to calculate the cut-off value for PPD. Sensitivity, specificity, positive predictive value, negative predictive value and correct diagnostic rate were evaluated.

RESULTS

Of the 80 post-partum women, PPD was found in nine cases (11.3%). The cut-off values for PPD were ≥10 for 4D-EPDS, ≥13 for 1M-EPDS and ≥21 for 1M-CES-D. No significant difference was found in the sensitivity, positive predictive value or negative predictive value among the three screening methods. However, a significant difference was found in the specificity, and the correct diagnosis rate and these values were relatively higher in 1M-EPDS.

CONCLUSION

Based on the result of this Japanese cohort, 1M-EPDS with a cut-off value of ≥13 might be appropriate for PPD screening although that of ≥9 is currently employed.

Transient vs enduring distress in late pregnancy using the EPDS: a brief longitudinal exploratory study

Background and Objective: The Edinburgh Postnatal Depression Scale (EPDS) is widely used to detect perinatal distress in women by one single administration. Recently, research has shown that during early pregnancy around half of the women scoring as 'possibly depressed' on the EPDS only have transient distress, when re-tested after few weeks. This finding may not occur if women are screened later in pregnancy, as their worries then may be more enduring; therefore an exploratory study was conducted to further investigate this issue. Methods: Pregnant women (N = 84) attending a public hospital in Italy completed the EPDS in their third trimester (x = 33 weeks) and again 8-42 days later (while still pregnant). They had not received professional mental health intervention in this time interval. Results: Approximately half of the women who initially scored high on the EPDS in late pregnancy no longer scored high just a few weeks later. Conclusions: Approximately half of women who initially score high on the EPDS when screened in pregnancy only have transient distress in both the second and third trimester. To label these women as being 'possibly depressed', and mixing them with women who show enduring distress, represents a possible weakness in research studies, and may also overburden clinical services. We would therefore recommend, as research and clinical practice, a second administration of the EPDS if a woman initially scores in the distressed range at any stage in pregnancy.

Depressive Symptoms in Late Pregnancy Disrupt Attentional Processing of Negative-Positive Emotion: An Eye-Movement Study

This study investigated biases for negative-positive information in component processes of visual attention (initial shift vs. maintenance of gaze) among women in late pregnancy with or without depressive symptoms. Eye movements were recorded while participants viewed a series of picture pairs depicting negative, positive, and neutral scenes. Initial orienting (latency and percentage of first fixation) and gaze duration were computed. Compared with neutral pictures, the group with major depressive symptoms (MDS) were less able to sense the positive emotion-related pictures and were over-responsive to negative emotion-related pictures. The group with suspicious depressive symptoms (SDS) had an attention bias toward both positive and negative emotion-related pictures. The group with no depressive symptoms (NDS) had an attention bias toward positive emotion-related pictures and had an initial attention avoidance tendency for negative emotion-related pictures. The initial gaze direction bias score for negative emotion-related pictures was positively correlated with the severity of depressive symptoms. Therefore, women with a risk of perinatal depression have a significant bias toward negative stimuli. Hypervigilant emotion processing during pregnancy may increase a woman's susceptibility to depression during late pregnancy. Attention away from negative information or attention toward positive information may provide a way of buffering emotional responses.

Stable factor structure of the Edinburgh Postnatal Depression Scale during the whole peripartum period: Results from a Japanese prospective cohort study

Early detection of perinatal depression is an urgent issue. Our study aimed to examine the construct validity and factor structure of the Japanese version of the Edinburgh Postnatal Depression Scale (EPDS) from a prospective cohort study from pregnancy to postpartum. A total of 1075 women completed all items of the EPDS at four time points: early pregnancy, late pregnancy, 5 days postpartum and 1 month postpartum. The participants were randomly divided into two sample sets. The first sample set (n = 304) was used for exploratory factor analysis, and the second sample set (n = 771) was used for confirmatory factor analysis. As a result, the Cronbach’s alpha coefficients of the EPDS items were 0.762, 0.740, 0.765 and 0.772 at the four time points. From the confirmatory factor analysis of the EPDS in a sample set of Japanese women from pregnancy to postpartum, the following three factors were detected: depression (items 7, 9), anxiety (items 4, 5) and anhedonia (items 1, 2). In conclusion, the EPDS is a useful rating scale, and its factor structure is consistently stable during the whole peripartum period.

Impact of perceived rearing and social support on bonding failure and depression among mothers: A longitudinal study of pregnant women

BACKGROUND

Although previous studies have reported associations between bonding failure, depression, social support among mothers, and perceived rearing, the causal relationships remain unclear.

METHODS

A total of 855 women (mean age, 32.4 ± 4.4 years) completed the Mother-Infant Bonding Questionnaire (MIBQ), the Edinburgh Postnatal Depression Scale (EPDS), the Japanese version of the Social Support Questionnaire, and the Parental Bonding Instrument in early pregnancy before week 25 (T1) and at 1 month after delivery (T2). We created a path model to clarify the causal relationships between perinatal bonding failure, depression, social support, and perceived rearing during pregnancy and at 1 month after delivery. The model was tested using structural equation modeling.

RESULTS

Our recursive model showed acceptable fit (chi-squared statistic/degree of freedom = 2.1, comparative fit index = 0.98, root mean square error of approximation = 0.04). It was revealed that: (1) at T1, higher overprotection significantly predicted MIBQ scores; (2) at T1, poorer social support significantly predicted both MIBQ and EPDS scores; and (3) at T1, both MIBQ and EPDS scores significantly predicted respective scores at T2.

CONCLUSIONS

These results showed that bonding failure in the postpartum period was significantly influenced by mothers' own perceived rearing and social support during pregnancy. In addition, depression in the postpartum period was strongly influenced by social support during pregnancy. These findings suggest that psychosocial interventions that focus on both mothers' recollections of their own upbringing and social support during pregnancy are effective for preventing bonding failure and depression in the postpartum period.

Threatened miscarriage and depressive and anxiety symptoms among women and partners in early pregnancy

BACKGROUND

Antenatal depression has been associated with poor maternal and fetal outcomes, and threatened miscarriage is often seen clinically to impact adversely on maternal wellbeing, notwithstanding the limited research evidence. Our study aims to examine the link between threatened miscarriage and antenatal depression and anxiety in an Asian obstetric population.

METHODS

We recruited 121 women and 68 partners facing threatened miscarriage, and 241 women and 180 partners experiencing uncomplicated pregnancies from a tertiary maternity hospital in Singapore. All participants completed a Patient Information Questionnaire and the Edinburgh Postnatal Depression Scale (EPDS).

RESULTS

The proportion of women with major depressive and anxiety symptomatology was significantly higher among women facing threatened miscarriage compared to those with stable pregnancies (depressive: 33.1% vs. 17.0%, p = 0.008; anxiety: 48.8% vs. 23.7%, p < 0.0001). Amongst their partners, there was a non-significant trend towards a similar finding (depressive: 10.3% vs. 7.2%, p = 0.439; anxiety: 23.5% vs. 18.9%, p = 0.478). Threatened miscarriage remained significantly associated with major depressive symptomatology after adjusting for potential confounders among women (OR 2.70; 95% CI 1.55, 4.71; p < 0.0001) but not among their partners (OR 1.47; 95% CI 0.56, 3.87; p = 0.430).

LIMITATIONS

This study is limited by its cross-sectional design and relatively small sample size for male partners.

CONCLUSION

Antenatal depressive and anxiety symptomatology affects one in four women in their first trimester, with even higher prevalence among women facing threatened miscarriage. Targeted depression and anxiety screening that includes women facing threatened miscarriages may facilitate early and efficient detection and management of mental health problems among pregnant women.
