Variability in use of cut-off scores and formats on the Edinburgh Postnatal Depression Scale: implications for clinical and research practice

Mental Health Diagnoses on the Mini International Psychiatric Interview Are Associated With Higher Scores on the Edinburgh Postnatal Depression Scale

OBJECTIVE

To understand if Mini International Psychiatric Interview (MINI) scores in pregnancy are associated with higher scores on the Edinburgh Postnatal Depression Scale (EPDS).

DESIGN

Cross-sectional pilot study of participants who completed the EPDS during pregnancy and were then invited to complete the MINI.

SETTING/LOCAL PROBLEM

An urban outpatient clinic at an academic medical setting from November 2020 to June 2021.

PARTICIPANTS

Convenience sample of 20 pregnant people.

INTERVENTION/MEASUREMENTS

Analysis of variance was used to examine differences based on EPDS scores and MINI symptom burden. Nonparametric tests (Mann-Whitney U or Kruskal-Wallis test) were used if assumptions were violated. Descriptive statistics were used to describe sample characteristics.

RESULTS

Nine participants screened 9 or higher on the EPDS and completed the MINI. There were no significant differences in demographic variables by EPDS score. There were significant differences between demographic variables, including employment status (p = .003) and type of health insurance (p = .019), between participants who met criteria for at least one diagnosis on the MINI and those who did not. Participants with public health insurance met the criteria for four more diagnoses compared to people with private insurance. Participants not employed full-time had nearly five more diagnoses compared to those employed full-time. Higher EPDS scores were correlated with all measured MINI symptoms or diagnoses. Higher EPDS scores were significantly correlated with and showed a moderate to strong positive correlation to suicidality and antisocial personality disorder.

CONCLUSION

Pregnant individuals who score 9 or higher on the EPDS may also have other severe mental health diagnoses. Recognizing perinatal mood and anxiety disorders in this population can inform the development of screening protocols and interventions during pregnancy to improve maternal access to mental health treatment and symptom reduction.

The role of breastfeeding and formula feeding regarding depressive symptoms and an impaired mother child bonding

Associations between depressive symptoms and breastfeeding are well documented. However, evidence is lacking for subdivisions of feeding styles, namely exclusive breastfeeding, exclusive formula feeding and a mixed feeding style (breastfeeding and formula feeding). In addition, studies examining associations between mother-child-bonding and breastfeeding have yielded mixed results. The aim of this study is to provide a more profound understanding of the different feeding styles and their associations with maternal mental health and mother-child-bonding. Data from 307 women were collected longitudinally in person (prenatally) and by telephone (3 months postnatally) using validated self-report measures, and analyzed using correlational analyses, unpaired group comparisons and regression analyses. Our results from a multinomial regression analysis revealed that impaired mother-child-bonding was positively associated with mixed feeding style (p = .003) and depressive symptoms prenatal were positively associated with exclusive formula feeding (p = .013). Further studies could investigate whether information about the underlying reasons we found for mixed feeding, such as insufficient weight gain of the child or the feeling that the child is unsatiated, could help prevent impaired mother-child-bonding. Overall, the results of this study have promising new implications for research and practice, regarding at-risk populations and implications for preventive measures regarding postpartum depression and an impaired mother-child-bonding.

The Worry Behaviors Inventory-Perinatal Revised: Adaptation and Initial Validation for Use in Perinatal Samples

Generalized anxiety disorder (GAD) is a leading mental health concern during pregnancy and the postpartum (perinatal) period. People with GAD engage in problematic behaviors to manage their distress. However, the extent of GAD behaviors during the perinatal period may not be adequately captured by the Worry Behaviors Inventory (WBI), the most comprehensive measure of GAD behaviors to date. We evaluated the structure of the initial WBI item-pool and then evaluated the internal consistency, construct validity, and predictive utility of the Perinatal Revised WBI (WBI-PR) in a sample of 214 perinatal women with and without GAD. A two-factor, 10-item scale was supported, and some of the retained items differed from the original WBI. Internal consistency of the WBI-PR was acceptable, and evidence of construct validity was demonstrated. The WBI-PR predicted GAD diagnostic status both alone and beyond existing generalized anxiety and depression symptoms. Implications of these findings are discussed.

Generating EQ-5D-3L health utility scores from the Edinburgh Postnatal Depression Scale: a perinatal mapping study

BACKGROUND

Perinatal depression (PND) describes depression experienced by parents during pregnancy or in the first year after a baby is born. The EQ-5D instrument (a generic measure of health status) is not often collected in perinatal research, however disease-specific measures, such as the Edinburgh Postnatal Depression Scale (EPDS) are widely used. Mapping can be used to estimate generic health utility index values from disease-specific measures like the EPDS.

OBJECTIVE

To develop a mapping algorithm to estimate EQ-5D utility index values from the EPDS.

METHODS

Patient-level data from the BaBY PaNDA study (English observational cohort study) provided 1068 observations with paired EPDS and EQ-5D (3-level version; EQ-5D-3L) responses. We compared the performance of six alternative regression model types, each with four specifications of covariates (EPDS score and age: base, squared, and cubed). Model performance (ability to predict utility values) was assessed by ranking mean error, mean absolute error, and root mean square error. Algorithm performance in 3 external datasets was also evaluated.

RESULTS

There was moderate correlation between EPDS score and utility values (coefficient:  - 0.42). The best performing model type was a two-part model, followed by ordinary least squared. Inclusion of squared and cubed covariates improved model performance. Based on graphs of observed and predicted utility values, the algorithm performed better when utility was above 0.6.

CONCLUSIONS

This direct mapping algorithm allows the estimation of health utility values from EPDS scores. The algorithm has good external validity but is likely to perform better in samples with higher health status.

Heart Rate Variability Measurement Can Be a Point-of-Care Sensing Tool for Screening Postpartum Depression: Differentiation from Adjustment Disorder

Postpartum depression (PPD) is a serious mental health issue among women after childbirth, and screening systems that incorporate questionnaires have been utilized to screen for PPD. These questionnaires are sensitive but less specific, and the additional use of objective measures could be helpful. The present study aimed to verify the usefulness of a measure of autonomic function, heart rate variability (HRV), which has been reported to be dysregulated in people with depression. Among 935 women who had experienced childbirth and completed the Edinburgh Postnatal Depression Scale (EPDS), HRV was measured in EPDS-positive women (n = 45) 1 to 4 weeks after childbirth using a wearable device. The measurement was based on a three-behavioral-state paradigm with a 5 min duration, consisting of rest (Rest), task load (Task), and rest-after-task (After) states, and the low-frequency power (LF), the high-frequency power (HF), and their ratio (LF/HF) were calculated. Among the women included in this study, 12 were diagnosed with PPD and 33 were diagnosed with adjustment disorder (AJD). Women with PPD showed a lack of adequate HRV regulation in response to the task load, accompanying a high LF/HF score in the Rest state. On the other hand, women with AJD exhibited high HF and reduced LF/HF during the After state. A linear discriminant analysis using HRV indices and heart rate (HR) revealed that both the differentiation of PPD and AJD patients from the controls and that of PPD patients from AJD patients were possible. The sensitivity and specificity for PPD vs. AJD were 75.0% and 90.9%, respectively. Using this paradigm, an HRV measurement revealed the characteristic autonomic profiles of PPD and AJD, suggesting that it may serve as a point-of-care sensing tool in PPD screening systems.

Are midwives trained to recognise perinatal depression symptoms? Results of MAMA (MAternal Mood Assessment) cross-sectional survey in Italy

PURPOSE

To assess the knowledge, clinical experience, and attitudes of Italian midwives toward perinatal depression (PND) and to explore how these factors impact the quality of care.

METHODS

We conducted a cross-sectional online survey among 152 midwives employed in public hospitals across Italy. The questionnaire covered a range of topics, including demographic data, professional experience, knowledge of PND symptoms, risk factors, and clinical management, as well as communication skills and personal experiences with PND cases.

RESULTS

A concerning 76.3% of midwives displayed inadequate knowledge of PND based on current scientific literature. Those with a more comprehensive understanding were notably more confident in their practice, expressing significantly fewer apprehensions about communicating with mothers (25.8% vs 74.2%) and lesser concerns about the mothers' future well-being (38.9% vs 62.95%). The survey results also emphasised the midwives' call for specialised guidelines and formal training in PND management and underscored the value of communication skills, continuity of care, and family engagement in supporting affected mothers.

CONCLUSION

This inaugural study sheds light on the current state of knowledge and attitudes among Italian midwives regarding PND. It pinpoints crucial areas for educational enhancement and practice improvement, suggesting that elevated levels of midwife expertise in PND could significantly elevate the standard of care and expedite early diagnosis and treatment.

Does parental mental health mediate the association between parents' perceived stress and parent-infant bonding during the early COVID-19 pandemic?

BACKGROUND

The spread of the COVID-19 virus was declared a pandemic in March 2020. New restrictions such as 'lockdowns' and 'social distancing' created challenges for individuals' work-life balance, financial situation, family life, and physical and mental health. The global population's stress levels rose in response to these changes, leading to a widespread deterioration of mental health. One group particularly affected was parents of infants and very young children. Poor parental mental health may disrupt parent-infant bonding, with negative consequences for infant well-being and development.

AIMS

To consider parent-infant bonding in relation to parents' perceived stress and psychological distress during the first lockdown, and to examine whether associations of stress with parent-infant bonding were mediated by parental mental health.

METHODS

DREAMCORONA (n = 738: 471 mothers and 267 partners) is a sub-study of the prospective German cohort study 'DREAM'. The SPSS modelling tool PROCESS was used to assess whether parental mental health mediated the relationship between parents' perceived stress response to the COVID-19 pandemic and parent-infant bonding, while controlling for covariates.

RESULTS

Higher levels of parental stress were strongly associated with higher levels of depression, anxiety, and aggression symptoms for both parents. In addition, there was a significant relationship between parents' self-reported stress levels and parent-infant bonding. This relationship was mediated by symptoms of depression and anxiety for fathers and by symptoms of anger-hostility for both parents.

CONCLUSION

Increased parental stress during the early pandemic was associated with poorer parent-infant bonding. This has important implications for the management of any future public health crises.

Physical Activity in Work and Leisure Time during Pregnancy, and Its Influence on Maternal Health and Perinatal Outcomes

BACKGROUND

Physical inactivity during pregnancy has been shown to be linked to an increased risk of complications. However, during pregnancy, doubts arise about what type, intensity and frequency of physical activity are most recommended.

OBJECTIVE

Our main objective was to know the level of physical activity (PA) and sedentary lifestyle in a representative sample of pregnant women in Málaga, one of the most populated cities in Spain. Also, we aimed to find out the effects of PA on obstetric and perinatal outcomes and on the mental health of pregnant women, differentiated according to PA intensity and domain.

METHODS

Five hundred and forty full-term pregnant women who had their obstetric checks in the maternity ward of the Regional University Hospital of Málaga were recruited through consecutive sampling. Participants answered a questionnaire that included the WHO Global Physical Activity Questionnaire (GPAQ), the Edinburgh Depression Scale (EDS), the Generalized Anxiety Disorder Scale (GAD-7) and some other sociodemographic and health-related questions. Subsequently, information about perinatal outcomes was obtained after birth.

RESULTS

Only 50.8% of women followed the WHO recommendations on activity. We found a high proportion of obese pregnant women and a direct effect of a sedentary lifestyle on the rate of cesarean sections and vulvovaginal tears in spontaneous births, as well as on the mental health of future mothers. Women's age, the number of children, BMI at the beginning of pregnancy and leisure time physical activity (LTPA) explained anxiety scores, and age, LTPA, BMI at the end of pregnancy and intense work-related physical activity (WTPA) predicted depression scores.

CONCLUSIONS

LTPA improves obstetric outcomes, helping to reduce the rate of cesarean sections and vulvovaginal tears, as well as reducing prenatal anxiety and depression.

Maternal depressive symptoms and child language development: Exploring potential pathways through observed and self-reported mother-child verbal interactions

Maternal depressive symptoms (MDS) in the postnatal period may impact children's later development through poorer quality parent-child interactions. The current study tested a specific pathway from MDS (child age 9 months) to child receptive vocabulary (4 ½ years) through both self-reported and observed parent-child verbal interactions (at both 2 and 4 ½ years). Participants (n = 4,432) were part of a large, diverse, contemporary pre-birth national cohort study: Growing Up in New Zealand. Results indicated a direct association between greater MDS at 9 months and poorer receptive vocabulary at age 4 ½ years. There was support for an indirect pathway through self-reported parent-child verbal interactions at 2 years and through observed parent-child verbal interactions at 4 ½ years. A moderated mediation effect was also found: the indirect effect of MDS on child vocabulary through observed verbal interaction was supported for families living in areas of greater socioeconomic deprivation. Overall, findings support the potential role of parent-child verbal interactions as a mechanism for the influence of MDS on later child language development. This pathway may be particularly important for families experiencing socioeconomic adversity, suggesting that effective and appropriate supportive parenting interventions be preferentially targeted to reduce inequities in child language outcomes.

Measuring post-traumatic stress after childbirth: a review and critical appraisal of instruments

BACKGROUND

Addressing psychological trauma after childbirth requires accurate measurement of its prevalence, risk factors, and outcomes using validated instruments that distinguish perceptions of traumatic birth, subclinical post-traumatic stress (PTS) symptoms, and symptoms meeting a diagnostic threshold.

OBJECTIVE

The purpose of this study was to review literature on psychological trauma following childbirth and appraise instruments that measure postpartum PTS.

METHODS

In January 2020, the authors searched for and evaluated peer-reviewed studies that quantitatively measured PTS following hospital-based live births in the United States, United Kingdom, Canada, Australia, Norway, Sweden, and Switzerland; 37 articles were selected and evaluated.

RESULTS

Levels of post-traumatic stress disorder were most commonly measured, followed by PTS symptoms. Diagnostic instruments suggested lower PTS prevalence estimates than those screening for or assessing PTS symptoms. Community samples yielded lower prevalence estimates than samples recruited from the internet or settings specifically addressing mental health. Measurement sooner after birth yielded higher estimates.

CONCLUSION

Study design, sample characteristics, instruments, and timing of measurements likely impact postpartum PTS prevalence estimates. Variation in these characteristics make it difficult to draw conclusions on the prevalence of postpartum PTS. Researchers should consider the appraisal of measurement tools presented here and use rigorous study methodology when studying traumatic birth experiences and evaluating interventions.

Associations of prenatal maternal depressive symptoms with cord blood glucocorticoids and child hair cortisol levels in the project viva and the generation R cohorts: a prospective cohort study

BACKGROUND

Prior studies have reported conflicting results regarding the association of prenatal maternal depression with offspring cortisol levels. We examined associations of high levels of prenatal depressive symptoms with child cortisol biomarkers.

METHODS

In Project Viva (n = 925, Massachusetts USA), mothers reported their depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS) during pregnancy, cord blood glucocorticoids were measured at delivery, and child hair cortisol levels were measured in mid-childhood (mean (SD) age: 7.8 (0.8) years) and early adolescence (mean (SD) age: 13.2 (0.9) years). In the Generation R Study (n = 1644, Rotterdam, The Netherlands), mothers reported depressive symptoms using the Brief Symptom Inventory (BSI) during pregnancy, and child hair cortisol was measured at a mean (SD) age of 6.0 (0.5) years. We used cutoffs of ≥ 13 for the EPDS and > 0.75 for the BSI to indicate high levels of prenatal depressive symptoms. We used multivariable linear regression models adjusted for child sex and age (at outcome), and maternal pre-pregnancy BMI, education, social support from friends/family, pregnancy smoking status, marital status, and household income to assess associations separately in each cohort. We also meta-analyzed childhood hair cortisol results from both cohorts.

RESULTS

8.0% and 5.1% of women respectively experienced high levels of prenatal depressive symptoms in Project Viva and the Generation R Study. We found no associations between high levels of maternal depressive symptoms during pregnancy and child cortisol biomarkers in either cohort.

CONCLUSIONS

The present study does not find support for the direct link between high levels of maternal depressive symptoms and offspring cortisol levels.

Associations between unintended fatherhood and paternal mental health problems: A systematic review and meta-analysis

BACKGROUND

Unintended pregnancies are linked to adverse parental mental health, yet little attention has been given to this relationship in fathers specifically. We aimed to meta-analyse associations between unintended pregnancies and mental health problems in fathers with children aged ≤36 months.

METHODS

We conducted keyword searches of Medline, CINAHL, Academic Search Complete, PsycInfo and Embase to February 2, 2022, and hand searched included reference lists.

RESULTS

Of 2826 records identified, 23 studies (N = 8085 fathers), reporting 29 effects, were eligible for meta-analysis. Included studies assessed depression, anxiety, stress, parenting stress, post-traumatic stress disorder (PTSD), alcohol misuse and psychological distress. Pooled estimates, from random effects meta-analyses, for all mental health outcomes (k = 29; OR = 2.28) and depression only (k = 19; OR = 2.36), showed that the odds of reporting mental health difficulties were >2-fold higher in men reporting unintended births compared with those reporting intended births. However, there was no evidence of association with anxiety (k = 2) or stress (k = 2). Overall, mental health problems were greater in low-income countries. No differences were found across parity, timepoint of mental health assessment, or instruments used to measure mental health symptoms.

LIMITATIONS

Analyses were limited by the use of retrospective assessment of pregnancy intention, and heterogeneity of measures used. Further, assessment of fathers' mental health was restricted to the first year postpartum. This review was limited to English language studies.

CONCLUSIONS

Unintended pregnancies present an identifiable risk for postpartum mental health problems in fathers.

Perinatal Trajectories of Maternal Depressive Symptoms in Prospective, Community-Based Cohorts Across 3 Continents

Importance

Depressive symptoms during pregnancy influence the development and health of the offspring, underscoring the need for timely intervention. However, the course of depressive symptoms across the perinatal period remains unclear, thus complicating screening and referral guidelines.

Objective

To examine the course and stability of depressive symptoms across the perinatal period in multiple, ethnically diverse independent observational cohorts.

Design, Setting, and Participants

This cohort study included self-reported depressive symptoms at multiple time points from 7 prospective cohorts spanning 3 continents (United Kingdom: Avon Longitudinal Study of Parents and Children from 1991 to 1995; Canada: Maternal Adversity, Vulnerability and Neurodevelopment from 2003 to 2007; Montreal Antenatal Well-being Study from 2019 to 2022; Alberta Pregnancy Outcomes and Nutrition from 2009 to 2014; and Singapore: Growing Up in Singapore Toward Healthy Outcomes from 2009 to 2013; Singapore Preconception Study of Long-Term Maternal and Child Outcomes from 2015 to 2019; and Mapping Antenatal Maternal Stress from 2019 to 2022). Participants were recruited either during preconception or pregnancy and observed into the postnatal period. All data from each cohort were analyzed from July 2022 to April 2023.

Main Outcomes and Measures

Self-reported depressive symptoms from pregnancy to 2 years following childbirth using either the Edinburgh Postnatal Depression Scale or the Center for Epidemiological Studies Depression were analyzed independently within each cohort using item response theory (IRT) techniques. K-means clustering was used to identify groups of participants with similar trajectories.

Results

A total of 11 563 pregnant women (mean [SD] age, 29 [5] years; 569 [4.9%] East Asian women; 304 [2.6%] Southeast Asian women; 10 133 [87.6%] White women) self-reported depressive symptoms from pregnancy to 2 years following childbirth. Analytic methods from Item Response Theory identified 3 groups of mothers based on depressive symptoms: low, mild, and high levels in each of the 7 cohorts. Mothers within and across all cohorts had stable trajectories of maternal depressive symptoms from pregnancy onwards. Mothers with clinical levels of depressive symptoms likewise showed stable trajectories from pregnancy into the postnatal period.

Conclusions and Relevance

In this study, trajectories of depressive symptoms remained stable from pregnancy across the perinatal period, a finding that conflicts with a continuing emphasis on postpartum or postnatal onset of depression that persists in some health policy guidelines. Interventions and public health initiatives should focus on reducing depressive symptoms during pregnancy in addition to following birth.

Depressive symptoms in mothers of preterm infants before and during COVID-19 restrictions in neonatal intensive care units

AIM

Little is known about the specific restriction measures used in intensive care units (NICUs) during the COVID-19 pandemic and their impact on parental well-being. Hence, this study aimed to assess the association between restriction measures and mothers' post-partum depressive symptoms.

METHODS

This comparative cohort study included mothers who gave birth before 35 weeks of gestation in Estonia. The outcome measure was mothers' post-partum depressive symptoms at the time of infant discharge, evaluated using the Edinburgh Postnatal Depression Scale (EPDS). In addition to the pandemic itself, the number of restriction measures in the NICUs was analysed as a potential explanatory factor for depressive symptoms.

RESULTS

The study included 55 mothers before the pandemic in 2018-2019 and 54 mothers during the COVID-19 pandemic in 2021. No significant difference was found in the median EPDS scores between the cohorts: 7.0 [interquartile range (IQR): 4.0-12.0] and 8.0 (IQR: 5.0-12.8) respectively. The number of restriction measures was not associated with mothers' EPDS scores in either unadjusted or adjusted models.

CONCLUSION

The COVID-19 pandemic or the number of restriction measures used in Estonian NICUs did not associate with mothers' post = partum depressive symptoms.

Exposure to phthalate metabolites, bisphenol A, and psychosocial stress mixtures and pregnancy outcomes in the Atlanta African American maternal-child cohort

BACKGROUND

Consumer products are common sources of exposure for phthalates and bisphenol A (BPA), which disrupt the endocrine system. Psychosocial stressors have been shown to amplify the toxic effects of endocrine disruptors but, information is limited among African Americans (AAs), who experience the highest rates of adverse pregnancy outcomes and are often exposed to the highest levels of chemical and non-chemical stressors. We examined the association between an exposure mixture of phthalate metabolites, BPA, and psychosocial stressors with gestational age at delivery and birthweight for gestational age z-scores in pregnant AA women.

STUDY DESIGN

Participants were enrolled in the Atlanta African American Maternal-Child Cohort (N = 247). Concentrations of eight phthalate metabolites and BPA were measured in urine samples collected at up to two timepoints during pregnancy (8-14 weeks gestation and 20-32 weeks gestation) and were averaged. Psychosocial stressors were measured using self-reported, validated questionnaires that assessed experiences of discrimination, gendered racial stress, depression, and anxiety. Linear regression was used to estimate individual associations between stress exposures (chemical and psychosocial) and birth outcomes. We leveraged quantile g-computation was used to examine joint effects of chemical and stress exposures on gestational age at delivery (in weeks) and birthweight for gestational age z-scores.

RESULTS

A simultaneous increase in all phthalate metabolites and BPA was associated with a moderate reduction in birthweight z-scores (mean change per quartile increase = -0.22, 95% CI = -0.45, 0.0). The association between our exposure mixture and birthweight z-scores became stronger when including psychosocial stressors as additional exposures (mean change per quantile increase = -0.35, 95% CI = -0.61, -0.08). Overall, we found null associations between exposure to chemical and non-chemical stressors with gestational age at delivery.

CONCLUSIONS

In a prospective cohort of AA mother-newborn dyads, we observed that increased prenatal exposure to phthalates, BPA, and psychosocial stressors were associated with adverse pregnancy outcomes.

Perinatal depression before and during the COVID-19 pandemic in New York City

BACKGROUND

Quarantining and isolation during previous pandemics have been associated with higher levels of depression symptomatology. Studies in other countries found elevated rates of anxiety and/or depression among pregnant people during the COVID-19 pandemic compared with prepandemic rates. New York City was the initial epicenter of the pandemic in the United States, and the effects of the pandemic on perinatal depression in this population are not well known.

OBJECTIVE

This study aimed to evaluate the rates of perinatal depression before and during the COVID-19 pandemic.

STUDY DESIGN

This is a single-center retrospective cohort study of patients screened for perinatal depression with the Edinburgh Postnatal Depression Scale at 2 private academic practices in New York City. This screen is done in these practices at the time of the glucose challenge test and at the postpartum visit. Patients aged ≥18 years who completed a screen at a postpartum visit and/or glucose challenge test from February 1, 2019 to July 31, 2019 and from February 1, 2020 to July 31, 2020 were identified, and the 2019 and 2020 groups were compared. The primary outcome was a positive screen, defined as ≥13 and ≥15 for postnatal and prenatal screens, respectively. Secondary outcomes included monthly changes in rates of positive screens and factors associated with perinatal depression. Data were analyzed using Mann-Whitney U test, chi-square, or Fisher exact test, and univariate and multivariate analyses with P<.05 defined as significant.

RESULTS

A total of 1366 records met the inclusion criteria; 75% of the prepandemic (2019) records were included, as opposed to 65% of pandemic (2020) records due to a lower screen completion rate in the pandemic cohort. The 2020 cohort had a higher proportion of Hispanic patients (P=.003) and higher rates of diabetes mellitus (P=.007), preterm labor (P=.03), and current or former drug use (P<.001). The 2019 cohort had higher rates of hypertension (P=.002) and breastfeeding (P=.03); 4.6% of the 2020 cohort had a suspected or confirmed COVID-19 infection. There was no difference in perinatal depression between the 2019 and 2020 cohorts (2.8% vs 2.6%; P>.99). This finding persisted after adjusting for baseline differences (adjusted odds ratio, 0.89; 95% confidence interval, 0.38-1.86; P=.76). There were no differences in rates of positive Edinburgh Postnatal Depression Scale by month. Several risk factors were associated with a positive screen, including being unmarried (P<.001), pulmonary disease (P=.02), depression (P<.001), anxiety (P=.01), bipolar disorder (P=.009), and use of anxiolytics (P=.04).

CONCLUSION

There were no differences in the rates of perinatal depression between the periods before and during the COVID-19 pandemic. The rate of perinatal depression in this cohort was below the reported averages in the literature. Fewer women were screened for perinatal depression in 2020, which likely underestimated the prevalence of depression in our cohort. These findings highlight potential gaps in care in a pandemic setting.

Comparison of placenta consumers' and non-consumers' postpartum depression screening results using EPDS in US community birth settings (n=6038): a propensity score analysis

BACKGROUND

Preventing postpartum depression (PPD) is the most common self-reported motivation for human maternal placentophagy, yet very little systematic research has assessed mental health following placenta consumption. Our aim was to compare PPD screening scores of placenta consumers and non-consumers in a community birth setting, using propensity score matching to address anticipated extensive confounding.

METHODS

We used a medical records-based data set (n = 6038) containing pregnancy, birth, and postpartum information for US women who planned and completed community births. We first compared PPD screening scores as measured by the Edinburgh Postpartum Depression Scale (EPDS) of individuals who consumed their placenta to those who did not, with regard to demographics, pregnancy characteristics, and history of mental health challenges. Matching placentophagic (n = 1876) and non-placentophagic (n = 1876) groups were then created using propensity scores. The propensity score model included more than 90 variables describing medical and obstetric history, demographics, pregnancy characteristics, and intrapartum and postpartum complications, thus addressing confounding by all of these variables. We then used logistic regression to compare placentophagic to non-placentophagic groups based on commonly-cited EPDS cutoff values (≥ 11; ≥ 13) for likely PPD.

RESULTS

In the unmatched and unadjusted analysis, placentophagy was associated with an increased risk of PPD. In the matched sample, 9.9% of women who ate their placentas reported EPDS ≥ 11, compared to 8.4% of women who did not (5.5% and 4.8%, respectively, EPDS ≥ 13 or greater). After controlling for over 90 variables (including prior mental health challenges) in the matched and adjusted analysis, placentophagy was associated with an increased risk of PPD between 15 and 20%, depending on the published EPDS cutoff point used. Numerous sensitivity analyses did not alter this general finding.

CONCLUSIONS

Placentophagic individuals in our study scored higher on an EPDS screening than carefully matched non-placentophagic controls. Why placentophagic women score higher on the EPDS remains unclear, but we suspect reverse causality plays an important role. Future research could assess psychosocial factors that may motivate some individuals to engage in placentophagy, and that may also indicate greater risk of PPD.

Written exposure therapy for treatment of perinatal PTSD among women with comorbid PTSD and SUD: A pilot study examining feasibility, acceptability, and preliminary effectiveness

OBJECTIVE

This pilot open trial examined the feasibility, acceptability, and preliminary effectiveness of Written Exposure Therapy (WET), a 5-session evidence-based intervention for posttraumatic stress disorder (PTSD) during pregnancy. Participants were pregnant women with comorbid PTSD and substance use disorder (SUD) receiving prenatal care in a high risk obstetrics-addictions clinic.

METHODS

A total of 18 participants with probable PTSD engaged in the intervention, and 10 completed the intervention and were included in outcome analyses. Wilcoxon's Signed-Rank analyses were used to evaluate PTSD and depression symptoms and craving at pre-intervention to post-intervention and pre-intervention to the 6-month postpartum follow-up. Engagement and retention in WET and therapist fidelity to the intervention manual were used to assess feasibility. Quantitative and qualitative measures of patient satisfaction were used to assess acceptability.

RESULTS

PTSD symptoms significantly decreased from pre-intervention to post-intervention (S = 26.6, p = 0.006), which sustained at the 6-month postpartum follow-up (S = 10.5, p = 0.031). Participant satisfaction at post-intervention was high. Therapists demonstrated high adherence to the intervention and excellent competence.

CONCLUSIONS

WET was a feasible and acceptable treatment for PTSD in this sample. Randomized clinical trial studies with a general group of pregnant women are needed to expand upon these findings and perform a full-scale test of effectiveness of this intervention.

How prenatal cortisol levels relate to grandmother-mother relationships among a cohort of Latina women

INTRODUCTION

As part of the human reproductive strategy, mothers receive childcare assistance from others. For kin, allomothers are adaptively incentivized to provide assistance due to inclusive fitness benefits. Previous studies across a broad range of populations identify grandmothers as particularly consistent allomothers. Minimal attention has been paid to the possibility that allomothers may begin investing in offspring quality during the prenatal stage of life. Here, we innovate within the area of grandmother allocare research by examining the prenatal stage of life and biopsychosocial mechanisms by which prenatal grandmother effects may be enacted.

METHODS

Data derive from the Mothers' Cultural Experiences study, a cohort of 107 pregnant Latina women in Southern California. At <16 weeks' gestation, we administered questionnaires, collected morning urine samples, and measured cortisol by enzyme-linked immunosorbent assay, correcting for specific gravity. We measured the soon-to-be maternal and paternal grandmothers' relationship quality, social support, frequency of seeing each other, communicating, and geographic proximity to pregnant mothers, that is, their daughters and daughters-in-law. These measures were self-reported by the pregnant mothers. We assessed how grandmother constructs related to the pregnant women's depression, stress, anxiety, and cortisol levels.

RESULTS

We observed benefits conferred by maternal grandmothers for mothers' prenatal mental health and lower cortisol levels. Paternal grandmothers also conferred mental health benefits to pregnant daughters-in-law, but higher cortisol levels.

CONCLUSION

Our results suggest that grandmothers, especially maternal grandmothers, are able to improve their inclusive fitness by caring for pregnant daughters, and allomother support may positively impact prenatal health. This work extends the traditional cooperative breeding model by identifying a prenatal grandmother effect, and, by examining a maternal biomarker.

Maternal racism experience and cultural identity in relation to offspring telomere length

Racism is a determinant of individual and offspring health. Accelerated telomere shortening, an indicator of cellular aging, is a potential mechanism through which parental experience of racism could affect offspring. Here we longitudinally evaluated the relationship between maternal lifetime experience of an ethnically-motivated verbal or physical attack, as reported in pregnancy, with offspring telomere length in 4.5-year-old children. We also explored the potential association between positive feelings about one's culture and offspring telomere length. Data come from a nationally representative, multi-ethnic birth cohort in Aotearoa New Zealand (NZ) (Māori N = 417, Pacific N = 364, Asian N = 381). In models adjusting for covariates, including socioeconomic status and health status, Māori mothers who experienced an ethnically-motivated physical attack had children with significantly shorter telomere length than children of Māori mothers who did not report an attack (B = - 0.20, p = 0.01). Conversely, Māori mothers who had positive feelings about their culture had offspring with significantly longer telomeres (B = 0.25, p = 0.02). Our results suggest that ethnicity-based health inequities are shaped by racism, with impacts for clinical care and policy. Future research should also evaluate the potential protective effects of positive cultural identity.

Psychometric properties of the difficulties in emotion regulation Scale in a perinatal sample

BACKGROUND

One in five pregnant and postpartum individuals experience an anxiety, depressive, and/or trauma-related disorder. Emotion dysregulation (ED) underlies the development and maintenance of various mental health disorders. The Difficulties in Emotion Regulation Scale (DERS) is the most comprehensive and commonly used measure of emotion dysregulation, yet limited evidence supports its use in the perinatal population. The present study aims to evaluate the validity of the DERS and its six subscales in a perinatal sample and to assess its predictive utility in identifying perinatal individuals with a disorder characterised by emotion dysregulation.

METHODS

Pregnant and postpartum individuals (N = 237) completed a diagnostic clinical interview and self-report measures of anxiety, depression, and perceived social support.

RESULTS

The DERS subscales demonstrated good internal consistency and construct validity, as it strongly correlated with measures of anxiety and depression and failed to correlate with a measure of perceived social support. Results from an exploratory factor analysis supported a 6-factor solution, suggesting structural validity. An ROC analysis revealed good to excellent discriminative ability for the DERS full scale and four of the subscales. Finally, an optimal clinical cut-off score of 87 or greater was established with a sensitivity of 81% for detecting a current anxiety, depressive, and/or trauma-related disorder.

CONCLUSIONS

This study provides evidence for the validity and clinical utility of the DERS in a treatment-seeking and community sample of pregnant and postpartum individuals.

Impact of trajectories of maternal postpartum depression on infants' socioemotional development

BACKGROUND

We assessed (a) the effects of postpartum depression (PPD) trajectories until 6 months postpartum on infants' socioemotional development (SED) at age 12 months, and (b) the mediating role of maternal self-efficacy (MSE), and the additional effect of postpartum anxiety at age 12 months.

METHODS

We used data from POST-UP trial (n = 1843). PPD was assessed using the Edinburgh Postnatal Depression Scale (EPDS) at 1, 3, and 6 months. Infants' SED was assessed at 12 months using the Ages and Stages Questionnaire-Social-Emotional (ASQ-SE). Structural equations were applied to estimate the effect of PPD trajectories on infants' SED and mediation by MSE. The additional effects of postpartum anxiety were assessed with conditional regression.

RESULTS

Higher levels of PPD over time were associated with a lower SED (coefficient for log-EPDS 3.5, 95% confidence interval 2.8; 4.2, e.g., an increase in the EPDS score from 9 to 13 worsens the ASQ-SE by 1.3 points). About half of this relationship was mediated by MSE. Postpartum anxiety had an independent adverse effect on SED.

CONCLUSIONS

PPD and postpartum anxiety have a negative impact on infants' SED. MSE as a mediator may be a potential target for preventive interventions to alleviate the negative effects of maternal psychopathology on infants' SED.

IMPACT

The trajectories of postpartum depression (PPD) from 1 month to 6 months were negatively related to infants' socioemotional development (SED) at age 12 months, underlining the importance of repeated assessment of PPD. Maternal self-efficacy (MSE) mediated the association between PPD and SED, implying MSE could be a potential target for preventive interventions. An additional independent negative effect of postpartum anxiety was identified, implying the assessment of postpartum anxiety also has a surplus value to identify mothers at risk.

Prevalence and risk factors for postnatal mental health problems in mothers of infants admitted to neonatal care: analysis of two population-based surveys in England

BACKGROUND

Previous research suggests that mothers whose infants are admitted to neonatal units (NNU) experience higher rates of mental health problems compared to the general perinatal population. This study examined the prevalence and factors associated with postnatal depression, anxiety, post-traumatic stress (PTS), and comorbidity of these mental health problems for mothers of infants admitted to NNU, six months after childbirth.

METHODS

This was a secondary analysis of two cross-sectional, population-based National Maternity Surveys in England in 2018 and 2020. Postnatal depression, anxiety, and PTS were assessed using standardised measures. Associations between sociodemographic, pregnancy- and birth-related factors and postnatal depression, anxiety, PTS, and comorbidity of these mental health problems were explored using modified Poisson regression and multinomial logistic regression.

RESULTS

Eight thousand five hundred thirty-nine women were included in the analysis, of whom 935 were mothers of infants admitted to NNU. Prevalence of postnatal mental health problems among mothers of infants admitted to NNU was 23.7% (95%CI: 20.6-27.2) for depression, 16.0% (95%CI: 13.4-19.0) for anxiety, 14.6% (95%CI: 12.2-17.5) for PTS, 8.2% (95%CI: 6.5-10.3) for two comorbid mental health problems, and 7.5% (95%CI: 5.7-10.0) for three comorbid mental health problems six months after giving birth. These rates were consistently higher compared to mothers whose infants were not admitted to NNU (19.3% (95%CI: 18.3-20.4) for depression, 14.0% (95%CI: 13.1-15.0) for anxiety, 10.3% (95%CI: 9.5-11.1) for PTS, 8.5% (95%CI: 7.8-9.3) for two comorbid mental health problems, and 4.2% (95%CI: 3.6-4.8) for three comorbid mental health problems six months after giving birth. Among mothers of infants admitted to NNU (N = 935), the strongest risk factors for mental health problems were having a long-term mental health problem and antenatal anxiety, while social support and satisfaction with birth were protective.

CONCLUSIONS

Prevalence of postnatal mental health problems was higher in mothers of infants admitted to NNU, compared to mothers of infants not admitted to NNU six months after giving birth. Experiencing previous mental health problems increased the risk of postnatal depression, anxiety, and PTS whereas social support and satisfaction with birth were protective. The findings highlight the importance of routine and repeated mental health assessments and ongoing support for mothers of infants admitted to NNU.

Psychometric properties of the PSWQ in a sample of pregnant and postpartum women

BACKGROUND

Generalized anxiety disorder (GAD)-characterised by excessive and uncontrollable worry-is the most frequently diagnosed anxiety disorder during pregnancy and the postpartum period. Identification of GAD often relies on assessment of its cardinal feature, pathological worry. The Penn State Worry Questionnaire (PSWQ) is the most robust measure of pathological worry to date but has not been extensively evaluated for use during pregnancy and the postpartum period. This study evaluated the internal consistency, construct validity, and diagnostic accuracy of the PSWQ in a sample of pregnant and postpartum women with and without a principal GAD diagnosis.

METHODS

One hundred forty-two pregnant and 209 postpartum women participated in this study. Sixty-nine pregnant and 129 postpartum participants met criteria for a principal diagnosis of GAD.

RESULTS

The PSWQ demonstrated good internal consistency and converged with measures assessing similar constructs. Pregnant participants with principal GAD scored significantly higher on the PSWQ than those with no psychopathology and postpartum participants with principal GAD scored significantly higher than those with principal mood disorders, other anxiety and related disorders, and no psychopathology. A cut-off score of 55 and 61 or greater was determined for detecting probable GAD during pregnancy and the postpartum period, respectively. Screening accuracy of the PSWQ was also demonstrated.

CONCLUSIONS

This study underscores the robustness of the PSWQ as a measure of pathological worry and probable GAD and supports its use in the detection and monitoring of clinically significant worry symptoms during pregnancy and postpartum period.

Threat versus deprivation in mother's childhood: Differential relations to hair cortisol and psychopathology in pregnancy

BACKGROUND

The negative effects of childhood maltreatment can be intergenerational, and the prenatal period may play an important role in this intergenerational transmission. Maternal hypothalamic-pituitary-adrenal (HPA) axis dysfunction and maternal psychopathology represent two mechanisms through which the effects of childhood maltreatment are hypothesized to be transmitted across generations.

OBJECTIVE

This study first sought to extend prior research on pathways of intergenerational transmission by examining whether mothers' childhood experiences of abuse versus neglect differentially relate to maternal HPA activity and to maternal psychopathology during the prenatal period. Second, exploratory analyses examined the links between maternal variables and their State Protective Service involvement as a parent, as an indicator of maladaptive caregiving.

METHODS

During the third trimester of pregnancy, 51 women reported on experiences of childhood maltreatment, on State Protective Service involvement as an adult parent, and on current depressive and post-traumatic stress symptoms, and provided a hair sample for cortisol assay.

RESULTS

Regression analyses indicated that greater severity of abuse, but not neglect, in childhood was associated with higher maternal depressive symptoms (β = 0.488, p = .020). In contrast, greater severity of neglect, but not abuse, in mothers' childhood was associated with lower maternal hair cortisol concentration (β = -0.437, p = .031). Lower maternal hair cortisol concentration, but not maternal psychopathology or severity of childhood abuse or neglect, in turn, was associated with State Protective Service involvement (β = -0.785, p < .001).

CONCLUSIONS

Findings extend prior work by suggesting that childhood abuse and neglect may have different sequelae for mothers during pregnancy and that these sequelae may have different relations to parenting.

Association between breastfeeding and perinatal depressive symptoms: A 13-months cross-lagged analysis in China

Breastfeeding is associated with perinatal depressive symptoms, the directionality of this relationship, however, remains unclear. Therefore, the present study aimed to evaluate the longitudinal relationship between breastfeeding and perinatal depressive symptoms. A longitudinal study was conducted from September 2018 to August 2020 in two cities of China. Depressive symptoms and breastfeeding behaviors were investigated during the third trimester and at 1, 3, 6, and 12 months postpartum. A total of 856 women participated in the present study. The cross-lagged model revealed that after adjustments were made for covariates, depressive symptoms at 3 and 6 months postpartum predicted breastfeeding at 6 and 12 months postpartum, respectively. Additionally, prenatal and 1-month postpartum depressive symptoms were not found to predict breastfeeding. Nor was found that breastfeeding, in turn, predicted depressive symptoms. These results indicated that women who experienced depressive symptoms at 3 months postpartum were more likely to discontinue breastfeeding. The first 3-months postpartum period seems to be the optimal time to identify and treat depressive symptoms to maintain and increase breastfeeding rates. Early intervention of perinatal depressive symptoms is warranted.

Effectiveness of cognitive behavioural therapy-based interventions for maternal perinatal depression: a systematic review and meta-analysis

BACKGROUND

Depression during the perinatal period (during pregnancy and the year after childbirth) is common and associated with a range of negative effects for mothers, infants, family members, and wider society. Although existing evidence suggests cognitive behavioral therapy (CBT) based interventions are effective for perinatal depression, less is known about the effect of CBT-based interventions on important secondary outcomes, and a number of potential clinical and methodological moderators have not been examined.

METHODS

A systematic review and meta-analysis primarily examined the effectiveness of CBT-based interventions for perinatal depression on symptoms of depression. Secondary aims examined the effectiveness of CBT-based interventions for perinatal depression on symptoms of anxiety, stress, parenting, perceived social support, and perceived parental competence; and explored clinical and methodological moderators potentially associated with effectiveness. A systematic search of electronic databases and other sources was performed up to November 2021. We included randomized controlled trials comparing CBT-based interventions for perinatal depression with control conditions allowing for the isolation of the effects of CBT.

RESULTS

In total, 31 studies (5291 participants) were included in the systematic review and 26 studies (4658 participants) were included in the meta-analysis. The overall effect size was medium (hedges g = - 0.53 [95% CI - 0.65 to - 0.40]); with high heterogeneity. Significant effects were also found for anxiety, individual stress, and perceived social support, however few studies examined secondary outcomes. Subgroup analysis identified type of control, type of CBT, and type of health professional as significant moderators of the main effect (symptoms of depression). Some concerns of risk of bias were present in the majority of studies and one study had a high risk of bias.

CONCLUSIONS

CBT-based interventions for depression during the perinatal period appear effective, however results should be interpreted with caution given high levels of heterogeneity and low quality of included studies. There is a need to further investigate possibly important clinical moderators of effect, including the type of health professional delivering interventions. Further, results indicate a need to establish a minimum core data set to improve the consistency of secondary outcome collection across trials and to design and conduct trials with longer-term follow-up periods.

Investigating the association between maternal childbirth intention, labor epidural analgesia, and postpartum depression: A prospective cohort study

BACKGROUND

Postpartum depression (PPD) is a general depressive episode after childbirth. Studies have shown that unmatched analgesic intention increases the risk of PPD, but the use of labor epidural analgesia (LEA) during childbirth can reduce this risk. We aimed to investigate the association between maternal childbirth intention, LEA, and PPD and risk factors that may be related to PPD.

METHODS

A total of 590 mothers were included in this prospective cohort study. Demographic, prenatal, intrapartum and postpartum data were recorded. We investigated the association between childbirth intention, LEA and PPD and assessed the interactions between two factors. Logistic regression analysis was used to screen variables that might be associated with the occurrence of PPD.

RESULTS

Overall, 130 of 451 women completing the study at 3 months had PPD (28.8 %). We did not find an association between unmatched childbirth intention, use of LEA and PPD (adjustOR = 0.684 CI 0.335-1.396, p = 0.296; adjustOR = 0.892, CI 0.508-1.565, p = 0.690). Chronic pain affecting daily life, prenatal EPDS, SAS, SSRS score, family accompaniment during labor, and 1-day numerical rating scale (NRS) score were significantly associated with PPD (p < 0.05).

LIMITATIONS

In the 3-month follow-up, we only recorded the EPDS score, not the pain score, and did not evaluate the association between postpartum chronic pain and PPD.

CONCLUSIONS

The association between maternal childbirth intention, LEA and PPD was not significant. Chronic pain affecting daily life, prenatal EPDS, SAS, SSRS score, family accompaniment during labor, and 1-day NRS score were significantly related to the occurrence of PPD (p < 0.05).

Relationships Between Maternal Perinatal Mood, Sex of Infant, and Disappointment with Sex of Infant in a North American Sample

OBJECTIVES

Little is known about the relationships between sex of infant, disappointment with sex of infant, and risk for perinatal depression, particularly in societies where the nature of parental sex preference is thought to be "balanced" between male and female offspring. We sought to explore relationships between these variables in a North American population.

METHODS

In this exploratory study, we used data from a large Canadian prospective longitudinal study in which data were collected at up to four timepoints: during pregnancy, and at 1 week, 1 month and 3 months postpartum. Data about sex of infant, maternal preference for, and disappointment in sex of infant were recorded at the first possible timepoint; while at each postpartum timepoint infant fussiness and EPDS scores were recorded. We performed a mixed-effects linear regression to evaluate relationships between these variables.

RESULTS

In our sample of N = 207 women, EPDS scores were higher for mothers of male versus female infants, and independently associated with infant fussiness. There was no interaction between sex of infant and maternal disappointment, or between maternal disappointment and EPDS scores.

CONCLUSIONS

Mothers of male infants may have slightly more depressive symptoms than mothers of female infants regardless of maternal preference for, or disappointment in sex of infant; sex-specific biological risk factors for PPD should be explored.

Childbirth fear in the USA during the COVID-19 pandemic: key predictors and associated birth outcomes

Background and objectives

Childbirth fear, which has been argued to have an adaptive basis, exists on a spectrum. Pathologically high levels of childbirth fear is a clinical condition called tokophobia. As a chronic stressor in pregnancy, tokophobia could impact birth outcomes. Many factors associated with tokophobia, including inadequate labor support, were exacerbated by the COVID-19 pandemic.

Methodology

We used longitudinally collected data from a convenience sample of 1775 pregnant persons in the USA to evaluate the association between general and COVID-19 pandemic-related factors and tokophobia using the fear of birth scale. We also assessed associations between tokophobia, low birth weight and preterm birth when adjusting for cesarean section and other covariates among a subset of participants (N = 993).

Results

Tokophobia was highly prevalent (62%). Mothers who self-identified as Black (odds ratio (OR) = 1.90), had lower income (OR = 1.39), had less education (OR = 1.37), had a high-risk pregnancy (OR = 1.65) or had prenatal depression (OR = 4.95) had significantly higher odds of tokophobia. Concerns about how COVID-19 could negatively affect maternal and infant health and birth experience were also associated with tokophobia (ORs from 1.51 to 1.79). Tokophobia was significantly associated with increased odds of giving birth preterm (OR = 1.93).

Conclusions and implications

Tokophobia increases the odds of preterm birth and is more prevalent among individuals who are Black, have a lower income, and have less education. Tokophobia may, therefore, be an underappreciated contributor to inequities in US birth outcomes. The COVID-19 pandemic likely compounded these effects.

Early pregnancy essential and non-essential metal mixtures and maternal antepartum and postpartum depressive symptoms

BACKGROUND

Mood disorders are common during and after pregnancy, and environmental metals may contribute to increased risk. Antepartum metal exposures have not been well characterized in relation to maternal depression. We evaluated the extent to which early pregnancy erythrocyte concentrations of essential and non-essential metals were prospectively associated with antepartum and postpartum depressive symptoms.

METHODS

Participants were 1226 women in Project Viva, a longitudinal cohort recruited during pregnancy (1999-2002). We measured concentrations of 11 metals in maternal first trimester erythrocytes (arsenic, barium, cadmium, cesium, copper, mercury, magnesium, manganese, lead, selenium, zinc). Using the Edinburgh Postnatal Depression Scale (EPDS), we assessed elevated depressive symptoms (≥13; 0-30 scale) at mid-pregnancy and at 6 and 12 months postpartum. We applied latent class mixed modeling to identify symptom trajectories. Adjusting for maternal sociodemographics and co-exposures, we examined associations between the metal mixture and depressive symptoms using logistic (for EPDS≥13)/multinomial (for symptom trajectories) regression and quantile g-computation.

RESULTS

In this cohort of moderately high socioeconomic status participants (e.g., 72 % college graduate), low-level metal concentrations were weakly to moderately correlated (Spearman: -0.24 to 0.59); the prevalence of depressive symptoms ranged from 9 % (mid-pregnancy) to 6 % (12 months postpartum); and three trajectories (stable low; elevated mid-pregnancy, then decreasing; moderate mid-pregnancy, then increasing) best fit the EPDS data. The early pregnancy erythrocyte metal mixture was not associated with maternal depressive symptoms in logistic, multinomial, or mixture models. For individual metals, most confidence intervals (CI) included the null. There was weak evidence that arsenic, lead, and selenium were moderately associated with elevated odds of depressive symptoms and/or trajectories. However, the odds ratios (95 % CI) per doubling of these three metals were imprecise [e.g., arsenic: 1.13 (0.94, 1.40) for EPDS≥13 at six months postpartum; lead: 1.19 (0.80, 1.77) for EPDS≥13 at mid-pregnancy; selenium: 2.35 (0.84, 6.57) for elevated mid-pregnancy, then decreasing versus stable low trajectory].

DISCUSSION

We did not observe strong, consistent evidence of associations between early pregnancy erythrocyte metal concentrations and subsequent maternal antepartum and postpartum depressive symptoms.

The effects of social support on depression and anxiety in the perinatal period: A mixed-methods systematic review

BACKGROUND

The social support offered to women in the perinatal period can buffer against depression and anxiety. The sources and types of support that reduce maternal levels of depression and anxiety are not well understood.

AIMS

To investigate the effects of structural and functional support on depression and anxiety in women in the perinatal period, and to explore the experiences of women around support during the perinatal period.

METHOD

A comprehensive search of six electronic databases was undertaken. Relevant studies published from January 2010 to April 2020 were included (PROSPERO reference number: CRD42020194228). Quantitative and qualitative studies were eligible if they reported the effects of, or had themes related to receiving functional or structural support in the perinatal period on women's levels of depression or anxiety. Qualitative data was synthesised using a thematic synthesis method. Quantitative data could not be pooled due to the lack of comparable RCTs or cohort studies and was thus presented in a narrative form.

RESULTS

Fifty-one articles (41 quantitative and 10 qualitative studies) were included. Analysis of quantitative studies demonstrated that insufficient support from partner, friends and family was associated with greater risk of symptoms of depression and anxiety. Distance-delivered interventions (via internet or telephone) diminished levels of depression and anxiety. Qualitative data revealed three overarching themes: appreciating all forms of support in the perinatal period, recognising appropriate and inappropriate support from health professionals and services, and having barriers to mobilising functional and structural support.

LIMITATIONS

Grey literature was not explored and search strategies only included English, Spanish and Portuguese language articles. The reviewed studies were heterogeneous and for this reason, quantitative assessments were not feasible.

CONCLUSION

Support from specific sources such as family members, friends who are also mothers, health professionals, neighbours, supervisors, co-workers and online communities still need to be further investigated. Implications for health professionals involved in the care of women in the perinatal period are discussed.

Cesarean Section and Child Development at 3 Years: A Prospective Cohort Study of First Births in Pennsylvania

OBJECTIVES

The rising cesarean birth rate globally has led to increasing concern about long-term unintended consequences, with particular focus on child neurodevelopmental outcomes. This study investigated the association between cesarean birth and early child neurodevelopment, measured at 3 years of age.

METHODS

This was a large multicenter longitudinal prospective cohort study of first-time mothers and their offspring in Pennsylvania. Mothers completed adapted versions of two measures of child development at 36- months postpartum: the modified Parents' Evaluation of Developmental Status (M-PEDS) and a shortened Ages and Stages Questionnaire (S-ASQ). Logistic regression models were used to assess the association between mode of delivery and delayed child development, controlling for confounding variables.

RESULTS

There were 695 (29.3%) children born by cesarean delivery and 1676 (70.7) born vaginally. Children born by cesarean had increased odds of scoring as developmentally delayed on both measures of child development: the M-PEDS (8.9% cesarean and 5.1% vaginal, adjusted odds ratio [aOR] = 1.58, 95% confidence interval [CI] = 1.11-2.24)) and the S-ASQ (6.3% cesarean and 3.3% vaginal, aOR = 1.66, 95% CI = 1.09-2.54). Additional factors associated with developmental delay were male sex, and the maternal factors of high pre-pregnancy body mass index, thyroid disorder, and diabetes.

CONCLUSION

In this large prospective cohort study of first-time mothers and their offspring, cesarean delivery was found to be associated with an elevated risk of delayed child development at age 3 years. This analysis highlights the importance of continued research to understand the impact of cesarean delivery on child development.

The P300 and late positive potential in pregnancy prospectively predict increases in depressive and anxious symptoms in the early postpartum period

Postnatal depression and anxiety disorders pose a major burden on maternal mental health. While psychosocial risk factors for perinatal depression and anxiety are well-researched, there is a dearth of research examining neural biomarkers of risk for postnatal increases in depression and anxiety. Previous studies suggest two different event-related potentials, the P300 and the late positive potential (LPP), may predict the course of depressive and anxious symptoms in non-perinatal populations. In a sample of 221 perinatal women, the present study utilized an emotional interrupt task administered in pregnancy to examine whether antenatal P300 and LPP amplitudes may predict change in depressive and anxious symptoms from pregnancy to the early postpartum period. Zero-order correlations and linear regressions revealed that a reduced antenatal P300 to target stimuli and an enhanced LPP to positive infant images were uniquely associated with postnatal depressive and anxiety symptoms, respectively, and that these ERPs were independent predictors beyond antenatal self-report measures of psychological symptoms. Furthermore, individuals with increased depressive symptoms in pregnancy exhibited a stronger negative association between antenatal P300 amplitude and postnatal depressive symptoms. The present findings underscore the possibility that the measurement of ERPs during pregnancy could serve as a screening tool for risk for perinatal depression and anxiety, and thereby assist with identifying at-risk individuals who might benefit from prevention efforts.

Longitudinal associations of psychosocial stressors with menopausal symptoms and well-being among women in midlife

OBJECTIVE

We examined longitudinal associations of psychosocial stressors with menopausal symptoms and well-being of women in midlife in a longitudinal cohort.

METHODS

This study is based on 682 women from Project Viva, a prospective cohort enrolled in 1999 to 2002 during pregnancy (median age = 33.3 y) and followed for almost two decades. In pregnancy, women self-reported psychosocial stressors (history of physical and sexual abuse and financial instability, from childhood to the current pregnancy). In 2017 to 2021 (median age, 51.6 y), they reported their menopausal symptoms (0-44 point scale) and well-being (general health [good/fair/poor vs excellent/very good], generalized anxiety symptoms, and depressive symptoms [both-more than minimal levels vs none/minimal]). We performed multivariable and logistic regression models to examine associations of psychosocial stressors with outcomes, adjusting for covariates.

RESULTS

History of physical abuse (reported by 37.3%) was associated with worse menopausal symptoms in the somatovegetative (odds ratio [OR], 0.46 points; 95% confidence interval [CI], 0.04-0.87 points) and psychological (OR, 0.52 points; 95% CI, 0.07-0.97 points) domains and with worse general health (OR, 1.73; 95% CI, 1.17-2.55) and greater depressive symptoms (OR, 1.74; 95% CI, 1.05-2.87). History of sexual abuse (7.7%) was associated with worse menopausal symptoms (OR, 2.81 points; 95% CI, 1.05-4.56) and worse general health (OR, 2.04; 95% CI, 1.04-4.03) but not with depressive symptoms. History of financial instability (10.8%) was associated with worse menopausal symptoms (1.92 points; 0.49 to 3.34), worse general health (OR, 2.16; 95% CI, 1.24-3.75), and greater depressive symptoms (OR, 2.68; 95% CI, 1.44-4.98). We observed no association between psychosocial stressors and generalized anxiety symptoms assessed at midlife.

CONCLUSIONS

Psychosocial stressors were associated with worse menopausal symptoms and well-being decades after initial report.

The association between time-to-pregnancy and postpartum depressive symptoms in a North American prospective cohort study

PURPOSE

To prospectively examine the association between time-to-pregnancy (TTP) and postpartum depression (PPD) and determine whether perceived stress during early pregnancy mediated this association.

METHODS

In Pregnancy Study Online, an internet-based preconception cohort study of pregnancy planners, participants completed questionnaires every 8 weeks for up to 12 months or conception, during pregnancy, and at postpartum. A total of 2643 women provided information on sociodemographic factors, reproductive history, and stress (i.e., Perceived Stress Scale [PSS]) during preconception and early pregnancy (completed at ∼4-12 weeks' gestation) and on postpartum depressive symptoms (i.e., Edinburgh Postnatal Depression Scale [EPDS]) at ∼6 months postpartum. We used multivariable modified Poisson regression models to estimate risk ratios and 95% confidence intervals (CIs) for the association between TTP (<3, 3-5, 6-11, ≥12 menstrual cycles) and PPD (EPDS score ≥13). Causal mediation analyses assessed the mediating role of early pregnancy PSS scores.

RESULTS

10.6% of women had EPDS scores indicating possible PPD (≥13). Compared with women who took less than 3 cycles to conceive, risk ratios for those who took 3-5, 6-11, and greater than or equal to 12 were 1.06 (95% CI: 0.77, 1.45), 1.24 (95% CI: 0.90, 1.70), and 1.31 (95% CI: 0.87, 1.99), respectively. Approximately 30% of the association between infertility (TTP ≥ 12) and PPD was mediated by early pregnancy PSS.

CONCLUSIONS

There was a modest positive dose-response association between delayed conception and PPD. Perceived stress in early pregnancy explained a small proportion of this association. However, given the width of the CIs, chance cannot be ruled out as an explanation for the observed association.

Implementing a Perinatal Depression Screening in Clinical Routine: Exploring the Patient's Perspective

Introduction Perinatal depression (PND) is a frequently observed mental disorder, showing a prevalence of up to 20% and resulting in unfavorable maternal and neonatal outcomes. Targeted screening for PND offers the potential to identify and treat undiagnosed cases and help prevent its deleterious consequences. The aim of the present study was to evaluate participants' personal attitudes and acceptance of a routine screening program for PND in pregnancy care, identify any potential underlying factors, and appraise the general perspective on perinatal mental health problems. Methods In total, 732 women in their second trimester of pregnancy took part in a PND screening program that was incorporated in routine prenatal care using the Edinburgh Postnatal Depression Scale (EPDS) and completed a web-based survey on screening acceptance. Results Participants viewed PND screening as useful (78.7%, n = 555/705), especially in terms of devoting attention to perinatal mental health problems (90.1%, n = 630/699), easy to complete (85.4%, n = 606/710), and without feelings of discomfort (88.3%, n = 628/711). Furthermore, women with previous or current mental health issues rated the usefulness of screening significantly higher, as did women with obstetric risks (p < 0.01 - p = 0.04). The final regression model explained 48.4% of the variance for screening acceptance. Conclusion Patient acceptance for PND screening was high in our study cohort, supporting the implementation of screening programs in routine pregnancy care with the potential to identify, sensitize, and treat undiagnosed patients to reduce stigmatization and offer access to tailored dedicated PND care programs.

Maternal use of acetaminophen during pregnancy and neurobehavioral problems in offspring at 3 years: A prospective cohort study

Background

Acetaminophen is one of the most commonly used drugs during pregnancy globally. Recent studies have reported associations between prenatal exposure to acetaminophen and neurobehavioral problems in children, including attention-deficit hyperactivity disorders. Little research has investigated these associations in preschool-age children or the potential confounding effects of prenatal stress. The purpose of this study was to examine associations between prenatal acetaminophen exposure and offspring neurobehavioral problems at the age of 3 years, with a focus on the potentially confounding effects of prenatal stress.

Methods

We used data from the First Baby Study, a prospective cohort study conducted in Pennsylvania, USA, with 2,423 mother-child pairs. Women reported medication use and completed a prenatal stress inventory during their third trimester. Child behavioral problems were measured at the age of 3 years, using the 7 syndrome scale scores from the Child Behavior Checklist (CBCL) for ages 1 ½ to 5.

Results

There were 1,011 women (41.7%) who reported using acetaminophen during pregnancy. Children who were exposed to acetaminophen during pregnancy scored significantly higher on 3 of the 7 CBCL syndrome scales: withdrawn, sleep problems and attention problems. Scores on all 7 of the CBCL syndrome scales were significantly associated with prenatal stress. After adjustment for prenatal stress and other confounders, 2 syndrome scales remained significantly higher in children exposed to acetaminophen: sleep problems (aOR = 1.23, 95% CI = 1.01–1.51) and attention problems (aOR = 1.21, 95% CI = 1.01–1.45).

Conclusions

These findings corroborate previous studies reporting associations between prenatal exposure to acetaminophen and attention problems in offspring and also show an association with sleep problems at age 3 years. Because use of acetaminophen during pregnancy is common, these results are of public health concern and suggest caution in the use of medications containing acetaminophen during pregnancy.

Instruments to Identify Symptoms of Paternal Depression During Pregnancy and the First Postpartum Year: A Systematic Scoping Review

Men often experience depressive symptoms during the transition to parenthood, but there is a lack of synthesized knowledge of instruments used to identify such symptoms. The aim of this scoping review was to identify instruments used to measure symptoms of depressive symptoms among fathers in pregnancy and the postpartum period, and to describe the instruments' characteristics and measurement properties. We identified studies published since 1990 through searches in databases such as MEDLINE, EMBASE, and PsycINFO and in gray literature. Pairs of reviewers selected relevant studies based on predetermined inclusion criteria. For each included study, we collected information relevant to the review question, guided by the COnsensus based Standards for the selection of health status Measurement INstruments (COSMIN). We included 13 instruments, described in 59 studies with about 29,000 participants across 25 countries. There were 12 validation studies. None of the instruments were uniquely developed for assessing paternal depressive symptoms related to fatherhood. The three most extensively examined instruments were the Edinburgh Postnatal Depression Scale (EPDS), Center for Epidemiologic Studies Depression Scale, and Beck Depression Inventory. For seven of the 13 instruments, there was no information reported about the instruments' properties beyond internal consistency, but for the other six instruments the 12 validation studies reported on both reliability and validity. No studies reported on measurement error or responsiveness. EPDS was both the most extensively assessed instrument and reported to be the most reliable and valid. Further research on instruments for identifying men with depression in pregnancy and the postpartum period is warranted.

Fetal sex-specific epigenetic associations with prenatal maternal depressive symptoms

Prenatal maternal mental health is a global health challenge with poorly defined biological mechanisms. We used maternal blood samples collected during the second trimester from a Singaporean longitudinal birth cohort study to examine the association between inter-individual genome-wide DNA methylation and prenatal maternal depressive symptoms. We found that (1) the maternal methylome was significantly associated with prenatal maternal depressive symptoms only in mothers with a female fetus; and (2) this sex-dependent association was observed in a comparable, UK-based birth cohort study. Qualitative analyses showed fetal sex-specific differences in genomic features of depression-related CpGs and genes mapped from these CpGs in mothers with female fetuses implicated in a depression-associated WNT/β-catenin signaling pathway. These same genes also showed enriched expression in brain regions linked to major depressive disorder. We also found similar female-specific associations with fetal-facing placenta methylome. Our fetal sex-specific findings provide evidence for maternal-fetal interactions as a mechanism for intergenerational transmission.

Childbirth Pain, Labor Epidural Analgesia, and Postpartum Depression: Recent Evidence and Future Directions

Pregnancy and childbirth are major life events for women and their families, characterized by physical, psychological, and emotional changes that can trigger anxiety, depression, and mental disorders in susceptible individuals. Acute labor pain is an independent risk factor for persistent pain in the postpartum period and is associated with depressive disorders. Epidural analgesia is a well-established technique that has commonly been regarded as the gold standard in pain management during labor. Although the relationships between labor pain, labor epidural analgesia, and postpartum depression have been studied by many investigators, the results of these studies are conflicting. Some literature suggest that labor epidural analgesia is associated with a reduction in the incidence of postpartum depression; however, other studies have failed to demonstrate this association. Unmet analgesic needs expectations, unmet birth expectations, and/or the quality of social support during labor may contribute to postpartum depression. The limitations of the published studies included differential misclassification of study variables and residual confounding, variations in the diagnosis of depression, and incomplete history data. Thus, future studies should include information on sociodemographic and patient-level variables and assessments of pain during labor or in the postpartum period. Better management of labor pain should be provided to prevent long-term morbidity and improve maternal and neonatal outcomes. Anesthesiologists could collaboratively work with obstetricians and perinatal psychiatrists to ensure that hospitals prioritize screening and treatment for postpartum depression.

Study protocol for Attachment & Child Health (ATTACHTM) program: promoting vulnerable Children’s health at scale

Background

Children’s exposure to toxic stress (e.g., parental depression, violence, poverty) predicts developmental and physical health problems resulting in health care system burden. Supporting parents to develop parenting skills can buffer the effects of toxic stress, leading to healthier outcomes for those children. Parenting interventions that focus on promoting parental reflective function (RF), i.e., parents’ capacity for insight into their child’s and their own thoughts, feelings, and mental states, may understand help reduce societal health inequities stemming from childhood stress exposures. The Attachment and Child Health (ATTACH^TM) program has been implemented and tested in seven rapid-cycling pilot studies (n = 64) and found to significantly improve parents’ RF in the domains of attachment, parenting quality, immune function, and children’s cognitive and motor development. The purpose of the study is to conduct an effectiveness-implementation hybrid (EIH) Type II study of ATTACH^TM to assess its impacts in naturalistic, real-world settings delivered by community agencies rather than researchers under more controlled conditions.

Methods

The study is comprised of a quantitative pre/post-test quasi-experimental evaluation of the ATTACH^TM program, and a qualitative examination of implementation feasibility using thematic analysis via Normalization Process Theory (NPT). We will work with 100 families and their children (birth to 36-months-old). Study outcomes include: the Parent Child Interaction Teaching Scale to assess parent-child interaction; the Parental Reflective Function and Reflective Function Questionnaires to assess RF; and the Ages and Stages Questionnaire – 3rd edition to examine child development, all administered pre-, post-, and 3-month-delayed post-assessment. Blood samples will be collected pre- and post- assessment to assess immune biomarkers. Further, we will conduct one-on-one interviews with study participants, health and social service providers, and administrators (total n = 60) from each collaborating agency, using NPT to explore perceptions and experiences of intervention uptake, the fidelity assessment tool and e-learning training as well as the benefits, barriers, and challenges to ATTACH^TM implementation.

Discussion

The proposed study will assess effectiveness and implementation to help understand the delivery of ATTACH^TM in community agencies.

Parent-infant closeness after preterm birth and depressive symptoms: A longitudinal study

Background

Preterm birth increases the risk for postpartum depression in both mothers and fathers, calling for strategies to alleviate and prevent depressive symptoms in parents of preterm infants. The aim of this study was to assess the association between early parent-infant closeness and later depressive symptoms among parents of preterm infants. We hypothesized that longer duration of closeness associate with fewer depressive symptoms in both parents.

Methods

This prospective cohort study included 23 neonatal intensive care units (NICUs) from 15 countries in 2018 to 2020. Each unit recruited families with preterm infants aiming to 30 families. The total duration of parents’ presence in the NICU, and separately parent-infant skin-to-skin contact and holding, were measured using a Closeness Diary up to 14  days. The Edinburgh Postnatal Depression Scale (EPDS) was used at discharge and at 4  months corrected age of the infant.

Results

The study included 684 mothers and 574 fathers. The median presence was 469   min (Q1 258 and Q3 1,087) per 24   h for the mothers and 259   min (Q1 100 and Q3 540) for the fathers; mean EPDS scores were 9.2 (SD 5.0) and 6.3 (SD 4.4) at discharge and 6.6 (4.7) and 4.3 (4.2) at 4  months, respectively. Parents’ presence and depressive symptoms varied greatly between the units. Parents’ presence as the total measure, or skin-to-skin contact and holding separately, did not associate with depressive symptoms in either mothers or fathers at either time point (adjusted).

Conclusion

No association was found between the duration of parent-infant closeness in the neonatal unit and parents’ depressive symptoms. The beneficial effects of family-centered care on parents’ depression seem to be mediated by other elements than parent-infant physical closeness. More research is needed to identify the critical elements which are needed to alleviate parents’ depression after NICU stay.

Applying Rasch methodology to examine and enhance precision of the Edinburgh Postnatal Depression Scale

BACKGROUND

The 10-item Edinburgh Postnatal Depression Scale (EPDS) is a widely used depression measure with acceptable psychometric properties, but it uses ordinal scaling that has limited precision for assessment of outcomes in clinical and research settings. This study aimed to apply Rasch methodology to examine and enhance psychometric properties of the EPDS by developing ordinal-to-interval conversion algorithm.

METHODS

The Partial Credit Rasch model was implemented using a sample of 621 mothers of infants (birth to 2 years old) who completed the EPDS as a part of a larger online survey.

RESULTS

Initial analysis indicated misfit to the Rasch model attributed to local dependency between individual EPDS items. The best model fit was achieved after combining six locally dependent items into three super-items resulting in non-significant item-trait interaction (χ²(49) = 46.61, p < 0.57), strong reliability (PSI = 0.86), unidimensionality and item invariance across personal factors such as age and mothers' education. This permitted generation of ordinal-to-interval conversion algorithms derived from person estimates of the Rasch model.

LIMITATIONS

Ordinal-to-interval conversion cannot be applied for individuals with missing data.

CONCLUSIONS

The EPDS met expectations of the unidimensional Rasch model after internal modifications, and its precision can be enhanced by using ordinal-to-interval conversion tables published in this article without the need to alter the original scale format. Scores derived from these conversion tables should decrease error and improve conformity with statistical assumptions in both clinical and research use of the EPDS, making monitoring of clinical status and outcomes more accurate.

Intimate Partner Violence and Perinatal Post-Traumatic Stress and Depression Symptoms: A Systematic Review of Findings in Longitudinal Studies

The link between maternal violence exposure and adverse obstetric outcomes is well-documented, but less is understood about the relationship between intimate partner violence (IPV) exposure and perinatal post-traumatic stress symptoms(PTSS) and depression in women around the world. A systematic review was conducted to synthesize empirical literature on the associations between IPV (e.g., before pregnancy, during pregnancy, postpartum) and post-traumatic stress and depression symptoms in the perinatal period. This review acknowledged the effects of IPV exposure timing, timing of assessment, and IPV subtypes. Forty-seven longitudinal studies met inclusion criteria and were reviewed to determine the effects of IPV exposure on perinatal mental health. Findings suggested a strong relationship between IPV exposure and perinatal mental health. Results were more consistent between perinatal mental health and IPV sustained close to or during the perinatal period than for lifetime IPV exposure. In general, physical, sexual, and psychological IPV were independently associated with perinatal depression and PTSS. Findings underscore the importance of theoretically driven research and the development of treatment protocols for women worldwide.

Benefits of Kangaroo Mother Care on the Physiological Stress Parameters of Preterm Infants and Mothers in Neonatal Intensive Care

It is well documented that the stress of separation of mother and baby can lead to short-term physiological instability as well as neurological, sociological or psychological consequences that may last a lifetime. Objective: The goal was to estimate the effect of kangaroo mother care (KMC) on physiological and biochemical parameters of preterm infant stress and maternal stress in neonatal intensive care. Methods: The investigation involved 112 preterm infants. Two groups were compared according to the mean duration of KMC during 12 days of study: the KMC group (mean duration more than 90 min daily) and the control group (less than 90 min). Results: Kangaroo mother care for more than 90 min on average per day in preterm infants is associated 12 days after the intervention with lower mean cortisol levels (p = 0.02), greater weight gain and less need for parenteral nutrition in preterm infants, as well as less postpartum depression (p = 0.02) and lower cortisol levels (p = 0.002) in the mothers of preterm infants. Conclusions: This study suggests that KMC can be used to improve the stress of preterm infants and their mothers, and that the greater weight gain observed in these preterm infants could contribute to a shorter average hospital stay and lower healthcare expenditure.

Mothers at risk of postpartum depression in Sri Lanka: A population-based study using a validated screening tool

Background

Postpartum depression is an important public health concern. The prevalence of postpartum depression is estimated to be 18% worldwide. The purpose of this study was to estimate the prevalence of mothers at risk of postpartum depression in Sri Lanka and to investigate its associated risk factors.

Methods

This was a cross-sectional study conducted among 975 mothers in Galle district, Sri Lanka. The prevalence of mothers at risk of postpartum depression was assessed using the Edinburgh Postpartum Depression scale (EPDS) which has been validated for screening for mothers at risk of postpartum depression in Sri Lanka with a cut-off score 9 or more. Prevalence was estimated using a cut-off 9 or more, 10 or more, 11 or more and 12 or more to assess the difference in prevalence using unvalidated cut-offs for screening. Data from routine records on pregnancy, delivery and postnatal care was collected to investigate possible predictors of EPDS score 9 or more (risk of postpartum depression). Univariate and multivariable logistic regressions were performed to identify risk factors for EPDS score 9 or more (risk of postpartum depression).

Results

The prevalence of mothers with EPDS score 9 or more was found to be 9.4% (95%CI: 7.8–11.4); EPDS score 10 or more was 5.6% (95%CI: 4.4–7.3). EPDS score 9 or more (risk of postpartum depression) was associated with the following risk factors: Former history of mental illness (aOR 32.9, 95%CI: 7.9–136.2), high maternal age 30–39 (aOR 2.2, 95%CI: 1.3–3.8), BMI 25.0–29.9 (aOR 2.6, 95%CI: 1.5–4.5), hypertension (aOR 3.6, 95%CI: 1.2–10.9) and newborn death (aOR 28.9, 95%CI: 4.5–185.1). One in five women reported thoughts of self-harm.

Conclusion

Around one in ten mothers in Sri Lanka experience symptoms of postpartum depression, highest risk among mothers who reported former history of mental illness and newborn death. The prevalence estimates were lower with a higher cut-off for screening and this highlights the importance of using the validated cut-off for screening in future studies on postpartum depression in Sri Lanka. Mothers at increased risk should be identified in antenatal care and are important targets of referral.

Validation of a Dari translation of the Edinburgh Postnatal Depression Scale among women of refugee background at a public antenatal clinic

OBJECTIVE

Identifying women at risk of depression and anxiety during pregnancy provides an opportunity to improve health outcomes for women and their children. One barrier to screening is the availability of validated measures in the woman's language. Afghanistan is one of the largest source countries for refugees yet there is no validated measure in Dari to screen for symptoms of perinatal depression and anxiety. The aim of this study was to assess the screening properties of a Dari translation of the Edinburgh Postnatal Depression Scale.

METHODS

This cross-sectional study administered the Edinburgh Postnatal Depression Scale Dari version to 52 Dari-speaking women at a public pregnancy clinic in Melbourne, Australia. A clinical interview using the depressive and anxiety disorders modules from the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) was also conducted. Interview material was presented to an expert panel to achieve consensus diagnoses. The interview and diagnostic process was undertaken blind to Edinburgh Postnatal Depression Scale screening results.

RESULTS

Cronbach's alpha coefficient for the Edinburgh Postnatal Depression Scale Dari version was good (α = 0.79). Criterion validity was assessed using the receiver operating characteristics curve and generated excellent classification accuracy for depression diagnosis (0.90; 95% confidence interval [0.82, 0.99]) and for anxiety diagnosis (0.94; 95% confidence interval [0.88, 1.00]). For depression, a cut-off score of 9, as recommended for culturally and linguistically diverse groups, demonstrated high sensitivity (1.00; 95% confidence interval [0.79, 1.00]) and specificity (0.88; 95% confidence interval [0.73, 0.97]). For anxiety, a cut-off score of ⩾5 provided the best balance of sensitivity (1.00; 95% confidence interval [0.72, 1.00]) and specificity (0.80; 95% confidence interval [0.65, 0.91]).

CONCLUSION

These results support the use of this Edinburgh Postnatal Depression Scale Dari version to screen for symptoms of depression and anxiety during pregnancy as well as the use of a lowered cut-off score.

Mothers' Experiences of Childbirth and Perspectives on Korean Medicine-Based Postpartum Care in Korea: A Qualitative Study

This study aimed to record the experiences of childbirth and postpartum care of postpartum women and gain an in-depth understanding of their experiences of Korean medicine-based postpartum healthcare. The investigator conducted a 60–90-min interview with the 8 participants (mean age 34 years), and the comments were analyzed using the thematic analysis method. The two major themes emerging from the participants’ comments were: “experience and awareness of childbirth and postpartum care” and “experiences of the Korean medicine-based postpartum program”. The first theme was analyzed in four primary categories: (1) experiences of breakdown of the body and mind; (2) impossibility of postpartum care without help; (3) experiences of relentless effort for recovery; and (4) experiences of body and mind recovery. The second theme was analyzed in four primary categories: (1) participation with vague expectations; (2) experiences of the effects of managing postpartum symptoms; (3) the need for a comprehensive Korean medicine management for postpartum women; and (4) suggested improvements for the Korean medicine-based postpartum program. Mothers recognized the importance of Korean medicine treatment during the postpartum period for the management of Sanhupung symptoms and postpartum care and reported the benefits of body warming, Sanhupung prevention, pain reduction, and sense of psychological stability.
