Review of validation studies of the Edinburgh Postnatal Depression Scale

Music and Sleep Hygiene Interventions for Pregnancy-Related Insomnia: An Online Randomized Controlled Trial

INTRODUCTION

Approximately 50% to 60% of all pregnant women suffer from insomnia during pregnancy. Pregnancy-related insomnia has been associated with severe outcomes for both mother and child postnatally. Currently, the treatment of pregnancy-related insomnia is often neglected due to a lack of suitable treatments. This online assessor-masked randomized controlled trial aimed to evaluate the effectiveness of music listening and sleep hygiene for treating pregnancy-related insomnia.

METHODS

We recruited first-time pregnant women at the end of the second trimester with a report of poor sleep. Participants in the music and sleep hygiene (MSH) group received standard sleep hygiene advice and were instructed to listen to music daily at bedtime for 4 weeks. They could choose from 6 sleep playlists of different genres. Participants randomized to the sleep hygiene alone (SH) group received standard sleep hygiene only. Primary outcomes were sleep quality measured with the Pittsburgh Sleep Quality Index (PSQI) and insomnia severity measured with the Insomnia Severity Index.

CLINICALTRIALS

gov Identifier: NCT04633395.

RESULTS

Among the 98 participants receiving the online intervention, 31 participants in the MSH group (62%) and 40 participants in the SH group (80%) completed the postintervention measurements. Both groups experienced improved sleep quality during the intervention period (PSQI change, -2.10; 95% CI, -3.27 to -0.93; P < .001), with no significant difference between the groups. Similarly, insomnia symptoms were reduced (Insomnia Severity Index change, -3.42; 95% CI, -5.02 to -1.83; P < .001) with no significant difference in the effect between groups. There was a significant difference in adherence to sleep hygiene between the MSH and SH groups (42% vs 8%; P = .007).

DISCUSSION

Sleep quality and insomnia severity can be improved in pregnant women with relatively simple interventions like music listening and sleep hygiene advice. These results align with previous research, but larger trials are recommended to support introduction into clinical practice.

The relationship of childhood maltreatment, adult sexual victimization, depressed mood and symptoms of trauma with fear of childbirth

BACKGROUND

Fear of childbirth (FoB) is experienced to some degree by most pregnant people and can be intense enough to merit treatment. Despite significant research on the topic of FoB, studies investigating various forms of maltreatment and mental health symptoms in relation to FoB are very limited. In particular, studies including multiple forms of maltreatment along with mental health symptoms as predictors of FoB are extremely limited. We sought to fill this gap and clarify the relative contributions of these variables to the prediction of FoB.

METHODS

This was a secondary analysis of data from pregnant people in Canada. Participants (N = 881) provided demographic and reproductive history information, completed self-report measures of FoB, childhood maltreatment (multiple forms), adult sexual victimization, depressed mood and symptoms of posttraumatic stress disorder (PTSD). They were also administered a diagnostic interview to assess for specific phobia, FoB. Analyses included descriptive information, Wilcoxon rank sum tests, linear and logistic regression, and path analysis.

RESULTS

Most forms of maltreatment showed some association with increased FoB. However, when assessed together, only emotional maltreatment remained a significant predictor of FoB. Both depressed mood and symptoms of PTSD contributed more to FoB than maltreatment, and mediated the relationship of emotional maltreatment with FoB. The only direct effects of childhood emotional maltreatment on FoB were for fears of medical interventions and feelings of embarrassment during labour and delivery.

LIMITATIONS

Study findings fill significant gaps in our understanding of the relationship between maltreatment, mental health symptoms and FoB. However, the study sample was limited to Canadian participants, most of whom were socio-economically advantaged, cis-gender women of European descent, thus limiting the generalizability of the findings. Further, as childhood maltreatment and sexual assault experiences in adulthood were reported retrospectively, study findings are also vulnerable to recall bias.

CONCLUSIONS

Findings contribute to our understanding of the relationship between childhood maltreatment, adult sexual victimization, mental health and FoB. These findings can facilitate future research and improved care via a focus on depressed mood, symptoms of PTSD, emotional maltreatment and specific fears of medical interventions and social discomfort as significant contributors to one's experience of FoB.

Mothers' and their children's emotional and behavioral symptom trajectories and subsequent maternal adjustment: Twenty-seven years of motherhood

BACKGROUND

This study aims to describe maternal depressive symptoms (MDS) trajectories in a longitudinal study extending from pregnancy to 27 years after the birth of the firstborn child. We also explored the associations of both MDS trajectories and child internalizing and externalizing problem trajectories with maternal adjustment (adaptive functioning, emotional and behavioral problems).

METHODS

The population-based study was conducted in Tampere, Finland, and the sample comprised 356 first-time mothers. MDS were screened with the Edinburgh Postnatal Depression Scale during pregnancy, first week after delivery, 2 and 6 months postnatally, and when the child was 4-5, 8-9, 16-17, and 26-27 years of age. The internalizing and externalizing problems of the children were assessed with the Child Behavior Checklist when the child was 4-5, 8-9, and 16-17 years of age. Maternal adaptive functioning and internalizing and externalizing problems were assessed with the Adult Self Report at 26-27 years after the birth of the first child. Complete follow-up data were available for 168 mothers.

RESULTS

We describe a three-group trajectory model of MDS (High Stable, Low Stable, Very Low). Elevated depressive symptom patterns were associated with less optimal maternal outcomes regarding both adaptive and problem dimensions. The child's internalizing and externalizing problem trajectories were associated with maternal internalizing and externalizing problems but not with maternal adaptive functioning.

LIMITATIONS

Maternal and child measures were based on maternal reports only.

CONCLUSIONS

The interconnectedness of the well-being of the mother and child should be noted in health and mental health services for adults and children.

Syrian refugee women's experiences of barriers to mental health services for postpartum depression

OBJECTIVE

To describe Syrian refugee women's experiences of the barriers to access mental health services for postpartum depression (PPD).

DESIGN

A descriptive qualitative study was conducted.

METHODS

Fifteen purposefully selected Syrian refugee women who scored ≥10 on the Edinburgh Postnatal Depression Scale participated in the semi-structured telephone interviews. Transcripts were coded verbatim and analysed thematically according to the dimensions of Levesque's model of patient-centred access to healthcare. Data were collected between August 2022 and February 2023.

RESULTS

Five themes with 14 subthemes were identified: (1) approachability covered lack of knowledge and misconceptions related to PPD and its treatment, lack of awareness of available psychosocial services and perceived need of mental health treatment; (2) acceptability comprised being a refugee, stigma of mental illness, cultural preferences of healthcare provider and language barrier; (3) availability and accommodation encompassed transportation barrier and location of the centre, no support for childcare and lack of time; (4) affordability included financial difficulties and health insurance coverage; (5) appropriateness comprised no screening for PPD and intermittent services with limited focus on mental health.

CONCLUSIONS

The findings of this study reveal that Syrian refugee women experienced multi-faceted complex barriers to access mental health services for PPD. It is important for health professionals, including nurses, and policymakers to address the cultural mental health needs of this population and establish strategies to protect their legal and health rights.

IMPACT

Our study has important practice and policy implications for establishing strategies designed specifically for refugee mothers to mitigate their perceived barriers to PPD treatment and ultimately improve their mental health.

REPORTING METHOD

The Consolidated Criteria for Reporting Qualitative Research was used.

PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution. Participants were Syrian refugee women with PPD symptoms and contributed only to the interviews and member checking.

Hypnobirthing Training for First-Time Mothers: Pain, Anxiety and Postpartum Wellbeing

Purpose

Childbirth represents a significant life event, bringing about both physical and emotional transformations in a woman's life. Among other psychological aspects associated with childbirth, labor pain, death anxiety, and postpartum depression have garnered significant attention in the field of maternal and reproductive health. This study is intended to evaluate how the effectiveness of hypnobirthing training alleviates labor pain, mitigates death anxiety enhances postpartum well-being reduces labor hours, and how anxiety exacerbates the duration of labor.

Methods

Data were collected from (N = 50) young and middle-aged postpartum women in the outpatient obstetrics and gynecology departments of the Civil Hospital, Waseer Gynecology Hospital and Basic Health Unit Jalal Ballagan in Gujranwala, Pakistan, by using the convenience sampling technique. Out of 50, women were divided into a control (N = 25) and an experimental group (N = 25). They were recruited during their 33 weeks of pregnancy until childbirth for hypnobirthing training. Numerical Pain Rating Scale (NPRS), Templer Death Anxiety Scale (TDAS), and Edinburgh Postnatal Depression Scale (EPDS) were used to collect participants' responses.

Results

Findings proved hypnobirthing training as a catalyst in significantly reducing labor pain, death anxiety, and postpartum depression. Furthermore, the analysis indicated that death anxiety exacerbates the labor duration hours and hypnobirthing decreases the labor hours in the experimental group of women.

Conclusion

It sheds light on the effectiveness of hypnobirthing training to enhance the birthing process. Findings underscore the significance of collaboration between obstetricians, psychologists, and mental health professionals to develop integrated care plans that address both physical and psychological aspects of childbirth.

Racism in obstetric care: a psychometric study of the Gendered Racial Microaggressions Scale among Global Majority birthing people in obstetric contexts

In the United States, maternal health inequities disproportionately affect Global Majority (e.g., Asian, Black, and Hispanic) populations. Despite a substantial body of research underscoring the influence of racism on these inequities, little research has examined how experiences of gendered racial microaggressions during pregnancy and birth impact racially and ethnically diverse Global Majority pregnant and birthing people in obstetric hospital settings. We evaluated the psychometric properties of an adapted version of Lewis & Neville's Gendered Racial Microaggressions Scale, using data collected from 417 Global Majority birthing people. Findings from our study indicate that our adapted GRMS is a valid tool for assessing the experiences of gendered racial microaggressions in hospital-based obstetric care settings among Global Majority pregnant and birthing people whose preferred languages are English or Spanish. Item Response Theory (IRT) analysis demonstrated high construct validity of the adapted GRMS scale (Root Mean Square Error of Approximation = 0.1089 (95% CI 0.0921, 0.1263), Comparative Fit Index = 0.977, Standardized Root Mean Square Residual = 0.075, log-likelihood c2 = -85.6, df = 8). IRT analyses demonstrated that the unidimensional model was preferred to the bi-dimensional model as it was more interpretable, had lower AIC and BIC, and all items had large discrimination parameters onto a single factor (all discrimination parameters > 3.0). Given that we found similar response profiles among Black and Hispanic respondents, our Differential Item Functioning analyses support validity among Black, Hispanic, and Spanish-speaking birthing people. Inter-item correlations demonstrated adequate scale reliability, α = 0.97, and empirical reliability = 0.67. Pearsons correlations was used to assess the criterion validity of our adapted scale. Our scale's total score was significantly and positively related to postpartum depression and anxiety. Researchers and practitioners should seek to address instances of gendered racial microaggressions in obstetric settings, as they are manifestations of systemic and interpersonal racism, and impact postpartum health.

Parental reports of hospital- and community-based follow-up services, self-efficacy, and symptoms of depression a few months after discharge of a prematurely born child

BACKGROUND

Many parents report the transition from hospital to home as challenging after the birth of a preterm-born child. This study investigates parental perceptions of community-based follow-up services after hospital discharge, alterations in parental self-efficacy during the early months at home, the prevalence of depressive symptoms among parents, and the relationship between these factors and both NICU experiences and children's regulative behaviors.

METHODS

In this second phase of a descriptive study, 110 parents returned a digital questionnaire when their child was four months corrected for prematurity. Parents were recruited while hospitalized with their child, in one of eight Norwegian neonatal intensive care units (NICUs). Thus, the study provides insight into follow-up services across a broad geographical range. Parents' perception of self-efficacy was reported on the Karitane Parenting Confidence Scale, and depressive symptoms were evaluated with the Edinburgh Postnatal Depression Scale (EPDS). Children's regulative behavior was reported on the 6-month version of the Ages and Stages Questionnaire: Social and Emotional (ASQ: SE). Using SPSS, associations between variables were investigated in multiple regression analysis in addition to descriptive analysis. Additionally, the examination of repeated measures of parental self-efficacy involved the application of linear mixed models.

RESULTS

Parents reported improved perception of self-efficacy from postdischarge to the children's age of four months (F (1,167) = 1233.2, p < 0.001). On average, fathers' self-efficacy improved more than that of mothers. Parents' perception of being well informed prior to discharge from hospital predicted improved self-efficacy (F [1, 29] = 10.4, p = 0.003). Reports of depressive symptoms were at a similar level as previously reported among new parents, as 10.4% of mothers and 6.7% of fathers reported EPDS scores ≥ 10 points. Parents' reports on ASQ: SE show that 15% of the children scored above the recommended cutoff score for three- to nine-month-old children. The parent-reported benefit of follow-up services showed considerable variation. The importance of specific knowledge about prematurity among public health nurses and physicians was frequently mentioned, and public health nurses were perceived as coordinators and mediators of various services.

CONCLUSIONS

Parents reported improved self-efficacy, and depressive symptoms at similar levels as new parents in general, a few months after discharge from hospital. Childrens' regulatory behavior were reported at levels comparable with term-born infants.

Are virtual services equivalent for mood, anxiety, and bonding? examining a perinatal intensive outpatient program

PURPOSE

Perinatal Intensive Outpatient Programs (IOPs) address severe perinatal mood and anxiety disorders (PMADs) and mother-infant relationship concerns. Given the impact of PMADs on mothers and infants, rapid transitions to virtual services (telehealth) amid COVID-19, and service expansions to populations in need, it is critical to evaluate how effectively virtual and in-person perinatal IOP services treat PMADs and mother-infant bonding.

METHODS

This quality-improvement record review examined patient records (n = 361) for a perinatal IOP from May 2016 to July 2023, amid multiple transitions between in-person and virtual services related to COVID-19, influenza, and respiratory syncytial virus. Patients in the completed measures sample (n = 115) completed depression (EPDS), anxiety (GAD-7, PASS), and mother-infant bonding (PBQ) measures over the first 3 weeks of treatment. Patients also anonymously provided program satisfaction ratings and qualitative feedback.

RESULTS

While anxiety and depression symptoms improved similarly across service settings, mother-baby bonding only significantly improved with in-person treatment. Patient symptom outcomes also differed by public/private insurance, race, and number of children. Patients reported high service ratings and overall satisfaction, and available feedback indicates some preference for in-person services.

CONCLUSION

As perinatal mental health services and IOPs continue to expand, virtual services can similarly address anxiety and depression symptoms and help to reach in-need populations. However, for perinatal IOPs, the core treatment target of mother-infant bonding may be uniquely addressed via in-person services.

Course of child social-emotional and sleep symptoms, parental distress and pandemic-related stressors during COVID-19

Research on the longitudinal courses of child social-emotional symptoms and sleep during the COVID-19 pandemic within societies would be of key value for promoting child well-being in global crises. We characterized the course of children's social-emotional and sleep symptoms before and throughout the pandemic in a Finnish longitudinal cohort of 1825 5- to 9-year-old children (46% girls) with four follow-up points during the pandemic from up to 695 participants (spring 2020-summer 2021). Second, we examined the role of parental distress and COVID-related stressful events in child symptoms. Child total and behavioral symptoms increased in spring 2020 but decreased thereafter and remained stable throughout the rest of the follow-up. Sleep symptoms decreased in spring 2020 and remained stable thereafter. Parental distress was linked with higher child social-emotional and sleep symptoms. The cross-sectional associations between COVID-related stressors and child symptoms were partially mediated by parental distress. The findings propose that children can be protected from the long-term adverse influences of the pandemic, and parental well-being likely plays a mediating role between pandemic-related stressors and child well-being. Further research focusing on the societal and resilience factors underlying family and child responses to the pandemic is warranted.

Mapping the link between socio-economic factors, autistic traits and mental health across different settings

LAY ABSTRACT

Autistic individuals are more likely than non-autistic individuals to experience a mental health condition in their lifetime, and this includes externalising and internalising symptoms. We know very little about how different environments and family conditions impact these symptoms for autistic individuals. Improving our understanding of these relationships is important so that we can identify individuals who may be in greater need of support. In this article, we seek to improve our understanding of how environmental and family conditions impact externalising and internalising symptoms in autistic and non-autistic people. To do this, we conducted analyses with two cohorts in very different settings - in Europe and South Africa - to ensure our findings are globally representative. We used advanced statistical methods to establish environmental and family conditions that were similar to each other, and which could be combined into specific 'factors'. We found that four similar 'factors' could be identified in the two cohorts. These were distinguished by personal characteristics and environmental conditions of individuals, and were named Person Characteristics, Family System, Parental and Material Resources. Interestingly, just 'Family System' was associated with internalising and externalising symptoms, and this was the same in both cohorts. We also found that having high traits of autism impacted this relationship between Family System and mental health conditions with opposite directions in the two settings. These results show that characteristics in the Family System are associated with internalising and externalising symptoms, and autistic persons are particularly impacted, reinforcing the notion that family stressors are important to consider when implementing policy and practice related to improving the mental health of autistic people.

Trajectories of maternal depressive and anxiety symptoms and child's socio-emotional outcome during early childhood

Maternal symptoms of depression and anxiety during pregnancy and early postnatal years are suggested to impose differential negative effects on child's socio-emotional development depending on the characteristics of the symptoms, such as timing, intensity, and persistence. The aim of this study was to identify trajectories of maternal depressive and anxiety symptoms from pregnancy until 2 years postpartum and to examine their relationship with child socio-emotional problems and competence at 2 and 5 years of age. The sample included 1208 mother-infant dyads from FinnBrain Birth Cohort study. Latent growth mixture modelling (LGMM) was utilized to model the trajectories of maternal depressive symptoms, measured using the Edinburgh Postnatal Depression Scale (EPDS), and general anxiety, measured with Symptom Checklist-90 (SCL-90) at 14, 24, and 34 weeks' gestation (gw) and at 3, 6 and 24 months postpartum. Maternal depression was also assessed at 12 months. Child socio-emotional problems and competence were evaluated using the Brief Infant Toddler Social Emotional Assessment (BITSEA) at 2 years and Strengths and Difficulties Questionnaire (SDQ) at 5 years. Relevant background factors and maternal concurrent symptomatology were controlled for. The trajectories of maternal depressive and anxiety symptoms were associated negatively with differential aspects of child long term socio-emotional outcomes from early toddlerhood to preschool years. The trajectories of depressive symptoms and high-level persistent symptoms that continued from pregnancy to two years of child age had the strongest negative association with child outcomes. This highlights the importance of identifying and treating maternal symptomatology, especially that of depression, as early as possible.

Occupational Pregnancy Discrimination Is Associated With Negative Health Impacts for Pregnant Persons and Their Children

OBJECTIVE

The aim of the study is to examine associations between occupational pregnancy discrimination, maternal, and child health.

METHODS

A nationwide sample of individuals currently in their third trimester of pregnancy who worked full-time (>35 hr/wk) were recruited. Surveys were completed during the third trimester and 6 weeks postpartum.

RESULTS

Respondents ( N = 183) were mostly White (57.9%), had at least a bachelor's degree (60.8%), and worked 40.3 hr/wk. Occupational pregnancy discrimination increased the odds of clinically significant depressive/anxiety symptoms by 8% and 17%, respectively (odds ratio = 1.1, 95% confidence interval: 1.0-1.1; odds ratio = 1.2, 95% confidence interval: 1.1-1.2). Discrimination was also associated with postpartum depression occurrence ( P = 0.02). Social support level mitigated the association between pregnancy discrimination, depressive symptoms (β = 2.1, P < 0.01), and anxiety symptoms (β = 7.25, P < 0.01).

CONCLUSIONS

Poorer mental health during and after pregnancy was associated with occupational pregnancy discrimination but effects were mitigated by social support.

The relationship of couples' time perspective to pregnant women's depression symptoms and stress: Preliminary results

OBJECTIVE

The aim of the study was to examine the relationship of a couple's time perspective to a woman's depression symptoms and stress.

METHOD

The participants were 48 pregnant women and 46 male partners of these women. The measurements have been taken during the first and third trimester. Women were examined by gynecologists during gynecological visits. During these visits measurements of gynecological pregnancy evaluation were administered. Then women completed online questionnaires: the Zimbardo Time Perspective Inventory Past Negative scale, the Dark Future Scale, the Edinburgh Postpartum Depression Scale and the Perceived Stress Scale at home. Men completed online questionnaires: the Zimbardo Time Perspective Inventory Past Negative scale, and the Dark Future Scale at home.

RESULTS

The results showed that women's past negative perspective in the first trimester was related to depression symptoms and stress in the first trimester. In the third trimester, women's future negative perspective was related to depression symptoms. Men's future negative perspective in the first trimester was related to women's stress in the first trimester. Moreover, the results suggest that the level of the woman's future negative perspective significantly increases during pregnancy.

CONCLUSIONS

Attitudes towards time of both the pregnant woman and her partner are related to the emotional state of the woman during pregnancy.

Socioeconomic resources moderate the relationship between maternal prenatal obsessive-compulsive symptoms and infant negative affectivity

Perinatal maternal depression, anxiety, and stress are associated with poor infant outcomes. However, no known study has investigated the effects of perinatal maternal obsessive-compulsive symptomatology on infant outcomes while considering important situational factors such as socioeconomic resources. Therefore, we investigated the effects of prenatal and postnatal obsessive-compulsive symptomatology on infant behavioral reactivity, beyond the effects of postnatal depressive symptomatology, at 6 months of age. It was expected that socioeconomic resources would moderate this relationship. We recruited 125 pregnant women from a Health Professional Shortage Area for mental health and primary care in the Midwest United States and interviewed them at approximately 34 weeks gestation and again at 6 months postnatally. They were administered questionnaires at both time points measuring obsessive-compulsive and depressive symptoms. Infant behavioral reactivity was gathered during 6-month follow-up through behavioral observation coding and maternal-report modalities. Maternal-reported infant negative affectivity at 6 months was related to greater severity of maternal postnatal depressive symptomatology, and socioeconomic resources moderated the relationship between maternal prenatal obsessive-compulsive symptoms and maternal-reported infant negative affectivity. However, neither of these relations was statistically significant when infant reactivity was quantified using behavioral observations.

Does Asthma Disrupt Psychological Wellbeing in Pregnancy?

(1) Background: Asthma is a very prevalent disease with special characteristics during pregnancy, however, little is known about its relationship to the psychological wellbeing of women in this period; we aimed to know whether depression and anxiety symptoms are more frequent in asthmatic pregnant women. (2) Methods: Family Apgar (week 20), Edinburgh Postnatal Depression Scale (weeks 20 and 32) and State-Trait Anxiety Inventory (STAI) (week 32) tests were administered to 738 pregnant women (81 asthmatics) in the Nutrition in Early Life and Asthma (NELA) birth cohort. (3) Results: There were no significant differences between asthmatic and non-asthmatic pregnant women in any of the different tests at any of the time points. The mean scores for the different tests and timepoints between asthmatic and non-asthmatic pregnant women were: Apgar 20, 17.9 ± 2.2 vs. 10.0 ± 2.2; Edinburgh 20, 6.7 ± 4.2 vs. 6.9 ± 4.3; Edinburgh 32, 5.9 ± 4.4 vs. 5.6 ± 4.3; and STAI 32, 16.7 ± 8.4 vs. 15.8 ± 8.3. The proportion of pregnant women out of the normal range score for any of the tests and time points was also similar in both populations. (4) Conclusions: asthma is not associated with the psychological wellbeing of pregnant women.

Association Between Mode of Delivery and Postpartum Depression: A Cross-Sectional Study in Saudi Arabia

Background This study was conducted to explore the association between postpartum depression (PPD) and mode of delivery in pregnant women. Methods This cross-sectional study was conducted in the western region of Saudi Arabia, among 173 women from the general population who met the inclusion criteria and participated in the study from April to September 2022. The Edinburgh Postnatal Depression Scale (EPDS) was used to assess PPD. Statistical analysis was performed using R version 3.6.3 (R Foundation for Statistical Computing, Vienna, Austria). Counts and percentages were used for categorical variables, and means ± standard deviation were used for continuous variables. Hypothesis testing was done at a significance level of 5%. Results It was reported by 59.5% of the respondents to be having depression. Compared to respondents who reported elective cesarean or natural delivery, those who reported emergency cesarean delivery had significantly higher average EPDS scores (p = 0.036). Positive correlations were found between depression scores and all Postpartum Bonding Questionnaire (PBQ) subscales, suggesting that higher PBQ subscale scores were associated with a greater risk of depression as determined by the EPDS questionnaire. In addition, a higher prevalence of PPD was associated with the presence of chronic illnesses (p = 0.016). Conclusion Our study indicated that although there was no correlation between mode of delivery and PPD, emergency cesarean section could contribute to PPD. Furthermore, other factors such as chronic illness and educational level can affect the risk of PPD.

The protective value of trait mindfulness for mothers' anxiety during the perinatal period

OBJECTIVES

Anxiety is highly prevalent in the perinatal period and can have negative consequences for the mother and the child. Extensive research has been done on risk factors for anxiety during the perinatal period, but less is known about protective factors. The current study aims to determine the relative contribution of trait mindfulness as a protective factor for anxiety.

METHODS

A longitudinal study design was used, with four measurement points: 12, 22, and 32 weeks of pregnancy (T0, T1, and T2, respectively), and 6 weeks postpartum (T3). General anxiety was measured at T1, T2, and T3, pregnancy-specific distress was measured at T1 and T2, mindfulness facets (acting with awareness, non-reacting, and non-judging) and partner involvement were measured at T1, and other known risk factors for anxiety were measured at T0. Multilevel regression models were used for statistical analyses.

RESULTS

Mindfulness facets measured at T1 were negatively associated with anxiety at T1, T2, and T3, and pregnancy-specific distress at T1 and T2. Of the mindfulness facets, non-judging was shown to have the largest protective effect against anxiety and pregnancy-specific distress. Also compared to partner-involvement and known risk factors, non-judging showed the largest effect on anxiety and pregnancy-specific distress.

CONCLUSIONS

For pregnant women who are at risk for developing or experiencing high levels of anxiety, it may be beneficial to participate in a mindfulness training with special attention for the attitudinal aspects of mindfulness.

Association of gestational thyroid function and thyroid peroxidase antibody positivity with postpartum depression: a prospective cohort study and systematic literature review with meta-analysis

IMPORTANCE

Postpartum depression (PPD) has a major impact on maternal and offspring well-being, with multiple possible risk factors: Studies on the association of thyroid peroxidase antibody (TPOAb) positivity and thyroid function with PPD provide heterogeneous results.

OBJECTIVE

To study the association of thyroid function and TPOAb positivity with PPD.

DESIGN

We assessed the association of TPOAb and thyroid function with PPD in a population-based prospective cohort study and performed a systematic literature review and meta-analysis.

METHODS

We measured thyroid stimulating hormone (TSH), free thyroxine (FT4), and TPOAb between 9- and 17-week gestation. Postpartum depression was assessed with Edinburgh Postpartum Depression Scale at 2-month postpartum and Brief Symptom Inventory at 2-, 6-, and 36-month postpartum. Additionally, we performed a systematic literature review and meta-analysis assessing this association.

RESULTS

In the present study, there was no association of thyroid function with PPD (TSH: odds ratio [OR] 0.83, 95% CI 0.58-1.19, P = .32; FT4: OR 0.99, 95% CI 0.95-1.05, P = .86) or TPOAb positivity with PPD (OR 0.79, 95% CI 0.47-1.33, P = .37). An impaired thyroidal response to human chorionic gonadotropin (hCG), a surrogate marker for TPOAb positivity, was associated with a lower risk of PPD (P for interaction TSH = 0.04; FT4 = 0.06). Our systematic review and meta-analysis included 3 articles that were combined with the present study. There was no statistically significant association of TPOAb positivity with PPD (OR 1.93, 95% CI 0.91-4.10, P = .08), but the results were heterogeneous (I2 = 79%).

CONCLUSIONS AND RELEVANCE

There was no significant association of TPOAb positivity, TSH, or FT4 with PPD. Our systematic review and meta-analysis revealed high heterogeneity of the current literature. Although TPOAb-positive women should be monitored for postpartum thyroiditis, our findings do not support routinely screening for PPD.

Testing lifecourse theories characterising associations between maternal depression and offspring depression in emerging adulthood: the Avon Longitudinal Study of Parents and Children

BACKGROUND

Maternal depression is a major determinant of offspring mental health. Yet, little is understood about how the duration and timing of maternal depression shapes youth risk for depressive symptoms, which if understood could inform when best to intervene. This study aimed to determine how the timing and duration of maternal depression was related to offspring depression in emerging adulthood, and if these associations varied by sex.

METHODS

We analysed data from the Avon Longitudinal Study of Parents and Children (a prenatal cohort in the Avon area of England, 1991-2003), n = 3,301. We applied the structured lifecourse modelling approach to maternal depression (assessed at 13 points from prenatal period to adolescence) and emerging adult depressive symptoms (age 21). Lifecourse models assessed were accumulation (sum of timepoints when maternal depression was reported), sensitive periods (each period assessed as one during which maternal depression has a stronger effect) and instability (frequent fluctuations in maternal depression).

RESULTS

Female adolescents (n = 2,132) had higher SMFQ scores (mean = 6.15, SD = 5.90) than males (n = 1,169, mean = 4.87, SD = 4.82). Maternal depression was most common in the infancy period (21.2% males; 21.4% females). For males, accumulation was the most appropriate lifecourse model; for each additional period of maternal depression, depressive symptoms in emerging adulthood increased by 0.11 (95% CI: 0.07, 0.15, one-sided p value ≤ .001). For females, exposure to maternal depression was associated with increasing depressive symptoms in emerging adulthood, with the largest effect in mid-childhood (increase of 0.27 units, 95% CI 0.03-0.50, p = .015 for difference between mid-childhood and other time-periods) and a smaller, equal effect at all other time-periods (increase of 0.07 units per time-period, 95% CI: 0.03-0.12, p = .002).

CONCLUSIONS

This study highlights the importance of ongoing maternal depression for the development of depression in offspring through to emerging adulthood. Because long-term exposure to maternal depression was particularly important, early interventions are warranted.

Predictive models for predicting the risk of maternal postpartum depression: A systematic review and evaluation

OBJECTIVES

Clinical prediction models have been widely used to screen and diagnose postpartum depression (PPD). This study systematically reviews and evaluates the risk of bias and the applicability of PPD prediction models.

METHODS

A systematic search was performed in eight databases from inception to June 1, 2022. The literature was independently screened, and data were extracted by two investigators using the checklist for critical appraisal and data extraction for systematic reviews of prediction modeling studies (CHARMS). The risk of bias and applicability was assessed using the Prediction Model Risk of Bias Assessment Tool (PROBAST).

RESULTS

After the screening, 12 studies of PPD risk prediction models were included, with the area under the ROC curve of the models ranging from 0.611 to 0.937. The most-reported predictors of PPD included several aspects, including prenatal mood disorders, endocrine and hormonal influences, psychosocial aspects, the influence of family factors, and somatic illness factors. The applicability of all studies was good. However, there was some bias, mainly due to inadequate outcome events, missing data not appropriately handled, lack of model performance assessment, and overfitting of the models.

CONCLUSIONS

This systematic review and evaluation indicate that most present PPD prediction models have a high risk of bias during development and validation. Despite some models' predictive solid performance, the models' clinical practice rate is low. Therefore, future research should develop predictive models with excellent performance in all aspects and clinical applicability to better inform maternal medical decisions.

Antenatal depression: Associations with birth and neonatal outcomes among women attending maternity care in Harare, Zimbabwe

INTRODUCTION

Antenatal depression is highly prevalent and is associated with negative birth and neonatal outcomes. However, the mechanisms and causality behind these associations remain poorly understood as they are varied. Given the variability in whether associations are present, there is need to have context-specific data to understand the complex factors that go into these associations. This study aimed to assess the associations between antenatal depression and birth and neonatal outcomes among women attending maternity care in Harare, Zimbabwe.

METHODS

We followed 354 pregnant women in second or third trimester, attending antenatal care services in two randomly selected clinics in Harare, Zimbabwe. Antenatal depression was assessed using the Structured Clinical Interview for DSM-IV. Birth outcomes included birth weight, gestational age at delivery, mode of delivery, Apgar score, and initiation of breastfeeding within one-hour postdelivery. Neonatal outcomes at six weeks postdelivery included infant's weight, height, illness, feeding methods and maternal postnatal depressive symptoms. The association between antenatal depression and categorical and continuous outcomes were assessed by logistic regression and point-biserial correlation coefficient, respectively. Multivariable logistic regression determined the confounding effects on statistically significant outcomes.

RESULTS

Prevalence of antenatal depression was 23.7%. It was associated with low birthweight [AOR = 2.30 (95% CI: 1.08-4.90)], exclusive breastfeeding [AOR = 0.42 (95%CI: 0.25-0.73)] and postnatal depressive symptoms [AOR = 4.99 (95%CI: 2.81-8.85)], but not with any other birth or neonatal outcomes measured.

CONCLUSIONS

The prevalence of antenatal depression in this sample is high with significant associations demonstrated for birth weight, maternal postnatal depressive symptoms and infant feeding methods Effective management of antenatal depression is thus crucial to the promotion of maternal and child health.

Oxytocin system polymorphisms rs237887 and rs2740210 variants increase the risk of depression in pregnant women with early abuse

Prepartum depression is associated with early adversity, pregnancy complications, preterm delivery, postpartum depression, and long-term effects on child neurodevelopment. The oxytocin (OXT) system is affected by early adverse experiences and has been associated with depression. In the current study, we investigated risk factors for prenatal depressive symptoms, mainly the effects of early childhood and adolescence trauma, in combination with the presence of certain variants of polymorphisms of OXT and OXT receptor (OXTR) genes. We hypothesized that early childhood and adolescence trauma has higher negative effects in carriers of genetic variants of the OXT/OXTR system, increasing their risk for depression. Early in pregnancy (8-14 weeks), 141 pregnant women from a Uruguayan population were asked to provide DNA samples and complete questionnaires that assessed their experience of child abuse, depression symptoms, and other variables that included demographic information. Our results showed that 23.5% of pregnant women had depressive symptoms. Several OXT and OXTR genetic variants were associated with higher risk of prepartum depression only in those pregnant women who suffered emotional abuse during infancy or adolescence. Logistic regression (Nagelkerke's R2  = .33) revealed that women who suffered early abuse and were carriers of the variants CC of rs2740210 (OXT) or AA of rs237887 (OXTR) had significantly higher risk of experiencing depressive symptoms. Antecedents of psychiatric disorders also contributed to the risk of depression. We conclude that emotional abuse contributes to the risk of depression in different ways in women carrying different OXT and OXTR genetic variants. Early detection and closer follow-up of women with child abuse and certain OXT genetic variants, among other risk factors, could reduce the long-term impact of prepartum depression.

App-based interventions for the prevention of postpartum depression: a systematic review and meta-analysis

BACKGROUND

This study explored whether psychosocial intervention applications (apps) are effective in preventing postpartum depression.

METHODS

We conducted an initial article search on 26 March 2020, and the updated search on 17 March 2023 on the electronic databases of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via Ovid, Scopus, PsycINFO, CINAHL, and ProQuest Dissertations & Theses A&I. Furthermore, we searched the International Clinical Trials Platform Search Portal (ICTRP), and Clinical Trials.

RESULTS

We identified 2515 references, and sixteen studies were ultimately included in this review. We conducted a meta-analysis of two studies on the onset of postpartum depression. There were no significant differences between the intervention and control groups (RR 0.80; 95% CI 0.62 to 1.04; P = 0.570). We performed a meta-analysis of the Edinburgh Postnatal Depression Scale (EPDS). The intervention group had significantly lower EPDS scores than the control group (mean difference -0.96; 95% CI -1.44 to -0.48; P < 0.001, I2 = 82%, Chi² = 62.75, P < 0.001; high heterogeneity).

CONCLUSION

This study presents the results of current RCTs on interventions with apps, including an app with an automated psychosocial component for preventing postpartum depression that has been conducted. These apps improved the EPDS score; furthermore, they may prevent postpartum depression.

Edinburgh Postnatal Depression Scale (EPDS) for screening for depression in the first year post delivery in a low-resourced rural setting in Kenya

Postnatal depression is one of the most common mental disorders among postnatal mothers and may have severe consequences for mothers and their children. Locally validated screening tools that can be self- or lay interviewer-administered are required to identify at-risk women, especially in settings with no mental health specialists. This study aimed to assess the validity and reliability of a culturally adapted version of the Edinburgh Postnatal Depression Scale (EPDS) in a local dialect (Kamba) in a Kenyan setting. Trained research assistants administered the local-language version of self-report scales (EPDS) to a sample of 544 Kamba-speaking women. The same scale was re-administered to the same research participants two weeks later by the same research assistants. The test scores were compared with an external 'gold standard' according to the DSM-IV criteria Mini-International Neuropsychiatric Interview for adults (MINI-Plus). The EPDS had an area under the curve (AUC) of 0.867 with 95% C.I of 0.836 to 0.894, with a cut-off point of ≥11, sensitivity of 81.0% (95% C.I 70.6-89.0) and specificity of 82.6% (95% CI 78.8-85.9). The positive predictive value (PPV) and negative predictive value (NPV) were 44.1% and 96.2%, respectively. The internal reliability was 0.852 and the test-retest reliability was 0.496. The EPDS showed good utility in detecting depressive disorder in Kamba-speaking postnatal women. It does not have to be administered by mental health workers (who are few in low- and middle-income countries); rather, this can be done by a trained lay interviewer.

Association between Hyperemesis Gravidarum in pregnancy on postnatal ability of infants to attend to a play task with their mother

Research indicates a higher prevalence of attention deficits in children exposed to HG in utero compared to controls with some claiming that the deficit is due to prenatal effects of malnutrition in HG mothers and others that it is due to maternal mental health after birth. The current study examines the effect of hyperemesis gravidarum (HG) diagnosis during pregnancy on infant attention controlling for maternal stress, depression anxiety and attachment. Thirty-eight infants mean age 4 months were videotaped with their mothers (19 mothers with a hyperemesis diagnosis and 19 controls) during play with a soft toy and looking at a picture book. Infant attention was operationalized as gaze direction towards the play activity, mother, and 'distracted' (indicated by looking away from play or mother). Mothers completed stress, depression, anxiety, and attachment questionnaires. HG exposed infants attended for significantly less time during play with a book or soft toy compared to controls. Maternal stress, depression, anxiety, and attachment did not differ in HG mothers and controls. Infant ability to attend to the toy, book, mother or being distracted did not relate to maternal postnatal attachment, or mental health. These results suggest that the prenatal environment, especially exposure to HG might be associated with reduced infant attention abilities independent of maternal postnatal health.

The gestational diabetes future diabetes prevention study (GODDESS): A partially randomised feasibility controlled trial

OBJECTIVES

To assess the feasibility of an ante- and post-natal lifestyle intervention for women with gestational diabetes mellitus (GDM) to reduce type 2 diabetes risk.

DESIGN

A partially randomised patient preference feasibility trial.

SETTING

Diabetes antenatal clinics in two inner-London hospitals, UK.

PARTICIPANTS

Pregnant women ≥18 years with a GDM diagnosis and pre-pregnancy body mass index of ≥25kg/m2.

INTERVENTION

Participants in the intervention group were offered four motivational interview-based sessions (two antenatally and two postnatally, at 3 and 6 months postpartum), a WhatsApp support group, a FitBit and electronic self-help resources.

OUTCOME MEASURES

Recruitment; retention; intervention dose received; data completion; adaptions; proportion achieving ≥5% weight loss; weight change, blood glucose; blood pressure; diet, physical activity, breastfeeding and depression. Clinical outcomes were measured at baseline and 6 months postpartum.

RESULTS

50 participants were recruited from 155 eligible women (32% recruitment rate). Thirty-four were recruited to the intervention group (23 following randomisation (RI-group) and 11 based on preference (PI-group)); and 16 to the control group (13 randomised (RC-group) and 3 preference (PC-group)). Attrition was 44% (n = 22/50). Forty-six percent (n = 6) of the intervention group (25% (n = 2) of the RI-group and 80% (n = 4) of the PI-group) achieved ≥5% weight loss compared to 8% (n = 1) in the control group (95% confidence interval (CI) -0.69 to 0.07). Mean weight change was -2.1kg±9.0 in the intervention group (0kg±5.4 in the RI-group and -5.4kg±13.0 in the PI-group) compared to +4.4kg±4.9 in the control group (RC +4.4kg ±5.3 and PC +4.7kg ±3.1, 95% CI -12.4 to 0.2).

CONCLUSIONS

Recruitment was feasible, but strategies to improve retention are needed. The findings suggest the intervention can support women with GDM to lose weight. The observed weight loss was primarily in women who preferred the intervention. Therefore, future trials may need to adopt a preference design and consider factors associated with preference.

A Comprehensive Review on Postpartum Depression

One of the most common psychological effects following childbirth is postpartum depression. Postpartum depression (PPD) has a significant negative impact on the child's emotional, mental as well as intellectual development if left untreated, which can later have long-term complications. Later in life, it also results in the mother developing obsessive-compulsive disorder and anxiety. Many psychological risk factors are linked with PPD. The pathophysiology of the development of PPD is explained by different models like biological, psychological, integrated, and evolutionary models, which relate the result of the condition with particular conditions and factors. This article also explains the role of methyldopa as a medication used during pregnancy and the postpartum phase with the development of PPD. There are different mechanisms by which methyldopa causes depression. The large-scale screening of the condition can be done by Edinburgh Postnatal Depression Scale (EPDS). The diagnosis can be made by clinical assessment, simple self-report instruments, and questionnaires provided to mothers. Currently, there has not been any specific treatment for PPD, but selective serotonin reuptake inhibitors (SSRIs) like sertraline are effective in acute management. Venlafaxine and desvenlafaxine are serotonin-norepinephrine reuptake inhibitors used for the relief of symptoms. The SSRI and tricyclic antidepressants (TCA) used in combination have a prophylactic role in PPD. Nowadays, women prefer psychological therapies, complementary health practices, and neuromodulatory interventions like electroconvulsive therapy more than previous pharmacological treatments of depression. Allopregnanolone drug made into sterile solution brexanolone leads to a rapid decline of PPD symptoms. PPD is a common and severe disorder that affects many mothers following childbirth but is ignored and not given much importance. Later it affects the child's psychological and intellectual abilities and mother-child bonding. We can easily prevent it by early diagnosis and timely care and management of the mother. Understanding the underlying pathophysiology would also go a long way in preventing and managing the disorder.

Associations between temperament dimensions and dental anxiety in parents of the FinnBrain Birth Cohort Study

We evaluated associations between dental anxiety and four temperament dimensions: effortful control, extraversion/surgency, negative affect and orienting sensitivity among 2558 parents in the FinnBrain Birth Cohort Study. Dental anxiety was measured with the Modified Dental Anxiety Scale, and temperament with the Adult Temperament Questionnaire. Associations between dental anxiety and temperament dimensions were modelled using linear and logistic (cut-off ≥ 19 for high dental anxiety) regression analyses adjusting for general anxiety and depressive symptoms, age and education. In women and men, dental anxiety was positively associated with negative affect (women β = 1.10; 95%CI 1.06-1.15; men β = 1.11; 95%CI 1.05-1.18) and negatively associated with effortful control (women β = 0.95; 95% CI0.92-0.99, men β = 0.90; 95% CI 0.85-0.95). In women, extraversion/surgency was also positively associated with dental anxiety (β = 1.04; 95%CI 1.00-1.08). For high dental anxiety, negative affect in women (OR = 2.00; 95%CI 1.31-3.06) and men (OR = 5.21; 95%CI 1.72-15.83) and for extraversion/surgency in women (OR = 1.50; 95%CI 1.01-1.47) associated positively with dental anxiety, but for effortful control, the association was not statistically significant. Dentists should understand that temperament dimensions affect the risk for dental anxiety more strongly than general anxiety or depressive symptoms. Dimensions negative affect and extraversion/surgency may increase and effortful control decrease the risk.

Mental disorders among adults formerly in out-of-home care: a systematic review and meta-analysis of longitudinal studies

While children and adolescents placed in child welfare or juvenile justice out-of-home care show higher prevalence rates of mental disorders compared to the general population, it remains unclear whether this pattern persists into adulthood. A quantitative synthesis of existing studies is lacking. The aim of this meta-analysis was to estimate the prevalence rates for mental disorders among adults with a foster or residential child welfare or juvenile justice care history, comparing them where possible to rates among the general population. PubMed, PsycInfo, EMBASE, and Web of Science were systematically searched for epidemiological studies published up to 28 October 2020. Nineteen studies, totaling 604,257 participants, met our inclusion criteria. Random-effects models were used for prevalence rates and odds ratios (OR) of mental disorders, and study quality was rated. A prevalence rate of 30% [95% CI (23.36, 37.36)] for any mental disorder in adults with a child welfare care history was found (3-17% for specific disorders). A prevalence rate of 45% [95% CI (42.38, 47.38)] for any mental disorder was found in adults with a juvenile justice care history (6-66% for specific disorders). For out-of-home placement history, adult mental disorders were significantly higher than in the general population (OR = 1.33-2.76). Studies differed in terms of methodology and the disorder groups considered, so heterogeneity between effect sizes ranged from low to high. Our findings suggest that the high risk that mental health issues will persist in adults with an out-of-home placement history needs to be taken seriously in the transition from adolescence to adulthood. The care systems involved need to collaborate and to be aware of these risks.

Autistic mothers' perinatal well-being and parenting styles

LAY ABSTRACT

Autistic people can have difficulties during pregnancy and after giving birth, such as difficulty getting health care that meets their needs. Autistic people may therefore have lower well-being than non-autistic people during this time. We asked autistic and non-autistic people to fill in questionnaires measuring stress, depression, anxiety and satisfaction with life. They were asked to do this once during pregnancy, once 2 to 3 months after giving birth and once 6 months after giving birth. At 6 months after giving birth, they also filled in questionnaires about parenting. The autistic parents had higher stress, depression and anxiety scores than the non-autistic parents. For both groups, scores for anxiety went down over time. There were no differences between the groups on satisfaction with their life or how confident they were as a parent. There were no differences between the groups on most areas of parenting style, although autistic parents scored lower on parenting discipline. This study suggests that autistic people may be more stressed, depressed and anxious than non-autistic people during pregnancy and after giving birth. Autistic people therefore need good quality support during this time. This study also suggests that autistic and non-autistic parents may be just as likely to parent in positive ways such as being sensitive to their baby's needs.

Genetic variants in the genes of the sex steroid hormone metabolism and depressive symptoms during and after pregnancy

PURPOSE

The aim of this study was to conduct an association analysis of depressive symptoms and polymorphisms in the ESR1, PGR, CYP19A1, and COMT genes in pregnant and postpartum women.

METHODS

The Franconian Maternal Health Evaluation Study (FRAMES) recruited healthy pregnant women prospectively for assessment of maternal and fetal health. The German version of the 10-item Edinburgh Postnatal Depression Scale (EPDS) was completed at three time points in this prospective cohort study. Visit 1 was at study entry in the third trimester of pregnancy, visit 2 was shortly after birth, and visit 3 was 6-8 months after birth. Germline DNA and depression measurements from 361 pregnant women were available for analysis. Six single nucleotide polymorphisms (SNPs) in the above-mentioned genes were genotyped. After reconstruction of haplotypes for PGR (rs1042838 and rs10895068) and CYP19A1 (rs10046 and rs4646), a multifactorial linear mixed model was applied to the data to describe the association between haplotypes and depression values. The single SNPs for ESR1 (rs488133) and COMT (rs4680) were analyzed separately using linear mixed models analogously.

RESULTS

The mean antepartum EPDS measurement was 5.1, the mean postpartal measurement after 48-72 h was 3.5, and the mean value 6-8 months postpartum was 4.2. The SNPs in PGR were reconstructed into three haplotypes. The most common haplotype was GG, with 63.43% of patients carrying two copies and 33.52% carrying one copy. For haplotype GA, the group of carriers of two copies (0.28%) was combined with the carriers of one copy (9.70%). Haplotype reconstruction using CYP19A1 SNPs resulted in three haplotypes. The most common haplotype was TC, with 25.48% of patients carrying two copies and 51.52% one copy. None of the haplotype blocks and neither of the two single SNPs showed any significant associations with EPDS values.

CONCLUSIONS

The candidate haplotypes analyzed in PGR and CYP19A1 and single SNPs in ESR1 and COMT did not show any association with depression scores as assessed by EPDS in this cohort of healthy unselected pregnant women.

Parity and Psychosocial Risk Factors Increase the Risk of Depression During Pregnancy Among Recent Immigrant Women in Canada

Prior investigations have examined risk factors associated to postpartum depression in immigrant women, but depression during pregnancy has received less attention. This study describes the prevalence and early determinants of antenatal depression among recent (≤ 5 years) and long-term immigrants (> 5 years), compared to Canadian-born women. 503 women completed standardized self-report questionnaires measuring sociodemographics and psychosocial factors. Multivariate logistic regressions identified first trimester risk factors for depression in each immigrant group. The prevalence of depressive symptoms was highest for recent immigrant (25.3-30.8%) compared to long-term immigrant (16.9-19.2%) and Canadian-born women (11.7-13.8%). Among recent immigrants, multiparity, higher stress and pregnancy-specific anxiety in early pregnancy increased the risk of antenatal depression. Among long-term immigrants, stress in the first trimester was significantly associated with antenatal depressive symptoms. Knowledge of modifiable risk factors (pregnancy-specific anxiety and stress) may help improve antenatal screening and inform the development of tailored interventions to meet the mental health needs of immigrant women during the perinatal period.

"How am I going to make it through pregnancy?" A qualitative examination of prenatal maternal stress

BACKGROUND

Prenatal maternal stress (PNMS) is common among childbearing women, and there is substantial evidence that persistent high levels of stress during pregnancy are associated with adverse birth outcomes and poorer postpartum mental health. Therefore, the purpose of this study was to examine the idiographic experiences of women who experienced elevated PNMS during their current or most recent pregnancy.

METHODS

Six focus groups were conducted, and data were collected from 26 women (n = 16 pregnant and n = 10 postpartum) at a large medical center in the United States (US). Data from the semi-structured focus group prompts were analyzed by two independent raters using conventional content analysis²¹ .

RESULTS

Three key themes emerged from the data: (1) Navigating Changing Circumstances, (2) Being a "Good" Mother, and (3) Loss of Control and Autonomy.

DISCUSSION

The current study offers one of the first in-depth examinations of the experiences of highly stressed pregnant women using a qualitative approach and identifies stressors rarely described in quantitative research. These findings suggest that women's ability to prioritize their self-care, and receive structural/institutional supports in the workplace and instrumental support at home, and overall health literacy promote successful coping with stress and highlight important future directions for intervention.

Is Validating the Cutoff Score on Perinatal Mental Health Mood Screening Instruments, for Women and Men from Different Cultures or Languages, Really Necessary?

Background: The most commonly used mood screening instrument in perinatal health is the Edinburgh Depression Scale. The screen-positive cut-off score on this scale, as for others, has been determined, via validation techniques, for over 20 languages/cultures, and for both women and men. While such validation appears to be considered essential, there are studies that could be interpreted to suggest that this is not an important consideration. Methods: Selective studies have been chosen to indicate these opposing points of view. Results: Examples of studies that support the notion of validating cut-off scores are described, as are examples of studies that appear not to support this point of view. Conclusions: (i) Clinical services and researchers need to be mindful of these opposing points of view, and openly discuss them when using screening cut-off scores for their respective populations. (ii) Researchers and Journals need to be more rigorous in ensuring this issue is correctly reported in studies, and/or openly discussed when relevant.

Factors that mediate the relationships between household socio-economic status and childhood Attention Deficit Hyperactivity Disorder (ADHD) in children and adolescents: A systematic review

BACKGROUND

ADHD is one of the most prevalent mental health disorders among children and adolescents. Household socio-economic status (SES) in early childhood is inversely related to ADHD later in childhood or adolescence. We conducted a systematic review to examine psychological, social and behavioural factors that mediate these relationships (PROSPERO Registration number: CRD42020182832).

METHODS AND FINDINGS

We searched Medline, EMBASE, PsychINFo, and Web of Science from inception until May 2020. Both authors independently reviewed abstracts and identified papers for inclusion. We sought primary observational studies (cohort, cross-sectional and case control studies) of general population-based samples of children and adolescents aged 18 and under that investigated potential mediators of the relationships between SES and ADHD. Studies based upon non-general population-based samples, twins or biochemical/physiological changes were excluded. Direct and indirect effects derived from standard validated mediation analysis were extracted for potential mediators. We assessed risk of bias using a modified NIH tool and synthesised quantitative data without meta-analysis according to the (SWiM) protocol because of heterogeneity between included studies. Family adversity, paternal and maternal ADHD symptoms, Home Learning Environment, breastfeeding duration and a combined fine motor and language score at age 2 may lie on the SES-ADHD pathway. Evidence concerning the influence of maternal depression/anxiety and adverse parenting was inconsistent across studies. There was no evidence that mother's health-related behaviour, family characteristics, child's consumption of fizzy drinks or other developmental characteristics at birth/during infancy lie on the SES-ADHD pathway. Publication bias may have been introduced by our decision not to search grey literature, not to approach study authors and limit the search to the English language.

CONCLUSIONS

Evidence for mediation of the SES-ADHD pathway in childhood/adolescence is under-researched. Maternal mental health, family adversity, parenting and health-related behaviours warrant further research based on longitudinal data and employing the most advanced mediation analysis methods.

Cortical Development Mediates Association of Prenatal Maternal Depressive Symptoms and Child Reward Sensitivity: A Longitudinal Study

OBJECTIVE

Maternal depression during pregnancy has long-term impacts on offspring. This study used neuroimaging and behavioral data from children aged 4 to 6 years and investigated whether prenatal maternal depressive symptoms (pre-MDS) associated with child cortical morphological development and subsequent reward-related behaviors in preschoolers.

METHOD

Pre-MDS was measured using the Edinburgh Postnatal Depression Scale at 26 weeks of pregnancy. Children (n = 130) underwent structural magnetic resonance imaging (MRI) at both 4 and 6 years of age. Child sensitivity to reward and punishment was reported by mothers when children were 6 years of age. Linear mixed-effect models examined pre-MDS associations with child cortical thickness and surface area. Mediation analysis examined whether cortical development mediated associations between pre-MDS and child sensitivity to reward and punishment.

RESULTS

The 3-way interactions of pre-MDS, age, and sex on cortical thickness and surface area were not statistically significant. We found a significant interaction of pre-MDS with sex on the cortical surface area but not on thickness or their growth from 4 to 6 years, adjusting for ethnicity, socioeconomic status, baseline age, and postnatal MDS as covariates. Higher pre-MDS scores were associated with larger surface areas in the prefrontal cortex, superior temporal gyrus, and superior parietal lobe (SPL) in boys, whereas the opposite pattern was seen in girls. The SPL surface area mediated the relationship between pre-MDS and sensitivity to reward in girls.

CONCLUSION

Prenatal maternal depression alters the cortical morphology of pre-schoolers in a sex-dependent manner.

Screening for Perinatal Anxiety Using the Childbirth Fear Questionnaire: A New Measure of Fear of Childbirth

Fear of childbirth affects as many as 20% of pregnant people, and has been associated with pregnancy termination, prolonged labour, increased risk of emergency and elective caesarean delivery, poor maternal mental health, and poor maternal-infant bonding. Currently available measures of fear of childbirth fail to fully capture pregnant people’s childbirth-related fears. The purpose of this research was to develop a new measure of fear of childbirth (the Childbirth Fear Questionnaire; CFQ) that would address the limitations of existing measures. The CFQ’s psychometric properties were evaluated through two studies. Participants for Study 1 were 643 pregnant people residing in Canada, the United States, and the United Kingdom, with a mean age of 29.0 (SD = 5.1) years, and 881 pregnant people residing in Canada, with a mean age of 32.9 (SD = 4.3) years for Study 2. In both studies, participants completed a set of questionnaires, including the CFQ, via an online survey. Exploratory factor analysis in Study 1 resulted in a 40-item, 9-factor scale, which was well supported in Study 2. Both studies provided evidence of high internal consistency and convergent and discriminant validity. Study 1 also provided evidence that the CFQ detects group differences between pregnant people across mode of delivery preference and parity. Study 2 added to findings from Study 1 by providing evidence for the dimensional structure of the construct of fear of childbirth, and measurement invariance across parity groups (i.e., the measurement model of the CFQ was generalizable across parity groups). Estimates of the psychometric properties of the CFQ across the two studies provided evidence that the CFQ is psychometrically sound, and currently the most comprehensive measure of fear of childbirth available. The CFQ covers a broad range of domains of fear of childbirth and can serve to identify specific fear domains to be targeted in treatment.

Validated tools to identify common mental disorders in the perinatal period: A systematic review of systematic reviews

BACKGROUND

Uncertainty remains regarding the validity of screening tools to detect common mental disorders (CMDs) during perinatal periods. This umbrella review aims to provide an up-to-date summary of psychometric properties of tools for the identification of perinatal CMDs.

METHODS

Reviews were identified via Ovid MEDLINE, PsychINFO, EMBASE, Global Health and Cochrane Database of Systematic Reviews electronic databases with no date or language restriction. Pooled sensitivity and specificity estimates and ranges were extracted and summarised using forest plots. Quality assessment was conducted using Measurement Tool to Assess Systematic Reviews (AMSTAR-2).

RESULTS

Of 7,891 papers identified, 31 reviews met inclusion criteria. 76 screening tools were identified; most frequently validated were Edinburgh Postnatal Depression Scale (EPDS) (n = 28 reviews), Beck's Depression Inventory (BDI) (n = 13 reviews) and Patient Health Questionnaire (PHQ) (n = 12 reviews). Forest plots demonstrated a pattern of decreasing sensitivity and increasing specificity with increasing cut-off scores. Sub-group analysis of data extracted from low quality reviews demonstrated wider 95% CIs and overall lower specificity. Validity also varied according to ethnicity, socio-economic background and age.

LIMITATIONS

Despite a low Covered Corrected Area (CCA) score the primary studies included within reviews overlapped; therefore we were unable perform meta-analysis.

CONCLUSIONS

The evidence suggests that the EPDS, PHQ and BDI are useful across a range of diverse settings but the context of tool application is a key factor determining validity. This review highlights that utilizing screening tools in clinical practice is complex and requires careful consideration of the population, context, and health system it will be used in.

Relationship Between Postnatal Depression of Mental Health Patients and the Psychological Health of Their Offspring

Postnatal depression is a major illness affecting maternal and family health. The rate of postnatal depression among mental health clients is postulated to be higher than in the community due to the added brain assault. Children of parents who are mental health clients are more likely to have psychological problems compared to children from other parents in the community. This study investigates the rate of postnatal depression among mental health clients and their offspring's psychological health. A total of 140 mental health clients were assessed using the Edinburgh Postnatal Depression Scale (EPDS). They subsequently completed the Strength and Difficulties Questionnaire (SDQ) regarding their children. The majority ethnicity was the Kadazan (40.7%). The mean age of mothers was 38.6 (7) years with most having a secondary education (53.6%) and a household income per month of < RM1000 per month (27.1%). The postnatal depression rate was 47.8%. Higher EPDS scores were associated with higher total SDQ scores in their offspring. Model 1 was unadjusted, giving an OR of 5.65 [95% CI (3.74, 7.55)], p < 0.001. After adjustment for confounders, Model 2 had an OR of 5.51 [95% CI (3.57, 7.46)], p < 0.001. More efforts need to be given to the early detection of maternal depression and its prompt treatment in mental health clients because of the relationship with the psychological health of the offspring.

Bed-Sharing in the First 6 Months: Associations with Infant-Mother Attachment, Infant Attention, Maternal Bonding, and Sensitivity at 18 Months

OBJECTIVE

The objective of this study was to investigate whether bed-sharing during the first 6 months of life is associated with infant's attachment and behavioral outcomes and mother's bonding and sensitive parenting at 18 months of age.

METHODS

The sample with complete longitudinal data comprised 178 infants and their caretakers. Bed-sharing was assessed with maternal report at term, 3, 6, and 18 months. Infant attachment was measured at 18 months using the strange situation procedure. Infant behavioral outcomes (i.e., poor attention/hyperactivity and task persistence) were assessed with 2 observational measures at 18 months. Maternal sensitivity was observed at 3 and 18 months, and mothers reported on bonding to their infant at term, 3, and 18 months.

RESULTS

Bed-sharing was common at term (41.2%), which decreased at 3 months (22.6%) followed by a slight increase at 6 (27.5%) and 18 months of age (31.3%). No associations between bed-sharing during the first 6 months and infant-mother attachment and infant behavioral outcomes at 18 months were found. Similarly, there were no associations between bed-sharing during the first 6 months and maternal bonding and sensitivity at consequent assessment points (i.e., 3 and 18 months).

CONCLUSION

Bed-sharing during the first 6 months is not associated with positive or negative outcomes about infant-mother attachment, infant behavior, maternal bonding, or sensitive parenting.

The Value of HPA Axis Hormones as Biomarkers for Screening and Early Diagnosis of Postpartum Depression: Updated Information About Methodology

Because of the high prevalence of postpartum depression (PPD) and the suffering involved, early diagnosis is urgent; however, current screening tools and diagnosis are inadequate. In addition to conventional methods such as the Edinburgh Postnatal Depression Scale and clinical interviews, several hormones in the hypothalamic-pituitary-adrenal (HPA) axis, such as corticotrophin-releasing hormone, adrenocorticotropic hormone, and cortisol, have been considered because of their critical roles in stress regulation in the mothers. The study designs are complicated, however, and so the effectiveness of these hormones as biomarkers for PPD is still controversial. Such inconsistency may have resulted from the variation in methodology between studies. The methodology problems in the investigation of PPD and HPA axis hormones have not been reported extensively. We therefore sought to summarize the methodological problems of studies published in the past decade, including the strengths and weaknesses of the examinations and the technological difficulties involved. Our findings suggest that (a) suitable samples and appropriate detection methods would reduce heterogeneity among trials; (b) the cutoff value of the scale test should be carefully selected for determining the performance of biomarker tests; (c) evaluation methods and criteria should be chosen with consideration of the tools feasible for use in local hospitals and population; and (d) the cost of diagnosis should be reduced. We hope that these findings provide insight for future investigations of HPA axis hormones as biomarkers for screening and early diagnosis of PPD.

Goals for reaching optimal wellness (GROWell): A clinical trial protocol of a digital dietary intervention for pregnant and postpartum people with prenatal overweight or obesity

Background:

Excess gestational weight gain (EGWG) is associated with multiple pregnancy complications and health risks for birthing people and their infants. Likewise, postpartum weight retention (PPWR), or not losing all pregnancy weight, has long-term health consequences. EGWG among people who enter pregnancy with overweight or obesity have worse obstetric outcomes and increased PPWR compared to women who gain within Institute of Medicine guidelines.

Methods:

This study protocol describes the details of a blinded, randomized clinical trial of GROWell: Goals for Reaching Optimal Wellness, a mHealth tool designed to improve diet quality among people who enter pregnancy with overweight or obese BMIs to help them achieve appropriate GWG and safe postpartum pregnancy weight loss. Individuals with overweight and obesity will be randomly assigned to an attention control or intervention arm. The intervention group will receive personalized, goal-oriented text messages regarding dietary choices, while the attention control group will receive text messages about healthy pregnancy, labor, delivery, and early infancy. Both groups will complete online surveys at baseline, follow up, 3 and 6 months postpartum.

Results and discussion:

Currently, 162 subjects have been enrolled. Outcomes associated with GWG and pregnancy are expected in late 2023, while outcomes on postpartum weight retention GROWell adherence are expected in late 2024. The results of this trial will support the use of an evidence-based mHealth tool to be integrated into clinical practice to reduce EGWG and PPWR among pregnant people with overweight and obese BMIs, a resource that is currently lacking.

Gender-specific associations between the dimensions of alexithymia personality trait and dental anxiety in parents of the FinnBrain Birth Cohort Study

We evaluated gender-specific associations of two dimensions of dental anxiety (anticipatory and treatment-related dental anxiety) with three dimensions of alexithymia: difficulty in identifying feelings, difficulty in describing feelings, and externally oriented thinking. The sample comprised 2558 parents from the general population participating in the FinnBrain Birth Cohort Study. Dental anxiety was measured with the Modified Dental Anxiety Scale and alexithymia with the 20-item Toronto Alexithymia Scale. Associations between dental anxiety and alexithymia dimensions were modelled using linear regression analysis adjusting for general anxiety and depressive symptoms, age, and education. Structural equation modeling assessed their interrelationships. In women, anticipatory dental anxiety was associated only with difficulty in identifying feelings, but treatment-related dental anxiety was associated with difficulty in identifying feelings, difficulty in describing feelings, and externally oriented thinking. In men, anticipatory dental anxiety was associated with only externally oriented thinking, whereas treatment-related dental anxiety was associated with difficulty in describing feelings, and with externally oriented thinking. Structural equation modelling showed that difficulty in identifying feelings was associated with anticipatory and treatment-related dental anxiety in women, whereas in men, only difficulty in describing feelings was associated with both types of dental anxiety. Anticipatory and treatment-related dental anxiety have different associations with alexithymia dimensions.

A Pilot Study to Evaluate the Impact of the HIV Infant Tracking System (HITSystem 2.0) on Priority Prevention of Mother-to-Child Transmission (PMTCT) Outcomes

We assessed the preliminary impact of the adapted HIV Infant Tracking System (HITSystem v2.0) intervention on prevention of mother-to-child transmission (PMTCT) outcomes using a matched cluster randomized design in two Kenyan government hospitals. Between November 2017 and June 2019, n = 157 pregnant women with HIV were enrolled and followed from their first PMTCT appointment until 12-weeks postpartum. Data from 135 women were analyzed (HITSystem 2.0: n = 53, standard of care (SOC): n = 82), excluding eight deaths, eight pregnancy losses, and six transfers/moves. The primary outcome, complete PMTCT retention, is an aggregate measure of attendance at all scheduled antenatal appointments, hospital-based delivery, and infant HIV-testing before 7-weeks postnatal. HITSystem 2.0 participants were more likely to receive complete PMTCT services compared to SOC (56.6% vs. 17.1% p < 0.001). In multivariate modeling, HITSystem 2.0 was the strongest predictor of complete PMTCT retention (aOR 5.7, [1.2-90.8], p = 0.032). SOC participants had 1.91 increased hazard rate of PMTCT disengagement; (aHR 6.8, [2.2-21.1]; p < 0.001).

Maternal psychosocial risk factors and child gestational epigenetic age in a South African birth cohort study

Accelerated epigenetic aging relative to chronological age has been found to be associated with higher risk of mortality in adults. However, little is known about whether and how in utero exposures might shape child gestational epigenetic age (EA) at birth. We aimed to explore associations between maternal psychosocial risk factors and deviation in child gestational EA at birth (i.e., greater or lower EA relative to chronological age) in a South African birth cohort study-the Drakenstein Child Health Study. Maternal psychosocial risk factors included trauma/stressor exposure; posttraumatic stress disorder (PTSD); depression; psychological distress; and alcohol/tobacco use. Child gestational EA at birth was calculated using an epigenetic clock previously devised for neonates; and gestational EA deviation was calculated as the residuals of the linear model between EA and chronological gestational age. Bivariate linear regression was then used to explore unadjusted associations between maternal/child risk factors and child gestational EA residuals at birth. Thereafter, a multivariable regression method was used to determine adjusted associations. Data from 271 maternal-child dyads were included in the current analysis. In the multivariable regression model, maternal PTSD was significantly and negatively associated with child gestational EA residuals at birth (β = -1.95; p = 0.018), controlling for study site, sex of the child, head circumference at birth, birthweight, mode of delivery, maternal estimated household income, body mass index (BMI) at enrolment, HIV status, anaemia, psychological distress, and prenatal tobacco or alcohol use. Given the novelty of this preliminary finding, and its potential translational relevance, further studies to delineate underlying biological pathways and to explore clinical implications of EA deviation are warranted.

Development of an unannounced standardized patient protocol to evaluate opioid use disorder treatment in pregnancy for American Indian and rural communities

BACKGROUND

Opioid use disorder (OUD) disproportionately impacts rural and American Indian communities and has quadrupled among pregnant individuals nationwide in the past two decades. Yet, limited data are available about access and quality of care available to pregnant individuals in rural areas, particularly among American Indians (AIs). Unannounced standardized patients (USPs), or "secret shoppers" with standardized characteristics, have been used to assess healthcare access and quality when outcomes cannot be measured by conventional methods or when differences may exist between actual versus reported care. While the USP approach has shown benefit in evaluating primary care and select specialties, its use to date for OUD and pregnancy is very limited.

METHODS

We used literature review, current practice guidelines for perinatal OUD management, and stakeholder engagement to design a novel USP protocol to assess healthcare access and quality for OUD in pregnancy. We developed two USP profiles-one white and one AI-to reflect our target study area consisting of three rural, predominantly white and AI US counties. We partnered with a local community health center network providing care to a large AI population to define six priority outcomes for evaluation: (1) OUD treatment knowledge among clinical staff answering telephones; (2) primary care clinic facilitation and provision of prenatal care and buprenorphine treatment; (3) appropriate completion of evidence-based screening, symptom assessment, and initial steps in management; (4) appropriate completion of risk factor screening/probing about individual circumstances that may affect care; (5) patient-directed tone, stigma, and professionalism by clinic staff; and (6) disparities in care between whites and American Indians.

DISCUSSION

The development of this USP protocol tailored to a specific environment and high-risk patient population establishes an innovative approach to evaluate healthcare access and quality for pregnant individuals with OUD. It is intended to serve as a roadmap for our own study and for future related work within the context of substance use disorders and pregnancy.

Association between mode of delivery and postpartum depression: A systematic review and network meta-analysis

BACKGROUND

Postpartum depression is one of the most common postpartum diseases, which has an important impact on the interaction between mother, infant, partner and family, as well as the long-term emotional and cognitive development of infants. However, there are still great disagreements on whether the delivery mode will affect the risk of postpartum depression. The purpose of this study is to explore whether the mode of delivery will affect the risk of postpartum depression through the comprehensive network meta-analysis of elective cesarean section, emergency cesarean section, instrumental vaginal delivery and spontaneous vaginal delivery.

METHODS

We searched in three electronic databases: PubMed, EMBASE and Cochrane Library.

RESULTS

This paper included 43 studies with a total sample size of 1,827,456 participants. Direct meta-analysis showed that the odds ratio of postpartum depression risk was 1.33 (95% confidence interval = [1.21, 1.46]) between cesarean section and vaginal delivery. The odds ratios of high Edinburgh Postpartum Depression Scale score between cesarean section and vaginal delivery in the three postpartum periods (within 2 weeks, within half a year and over half a year) were basically the same. There was no difference between cesarean section and vaginal delivery in the risk of severe postpartum depression at the Edinburgh Postpartum Depression Scale cut-off point ⩾13 (odds ratio = 1.07; 95% confidence interval = [0.99, 1.16]). Network meta-analysis showed that the risk of postpartum depression in the pairwise comparisons emergency cesarean section vs spontaneous vaginal delivery and elective cesarean section vs spontaneous vaginal delivery was odds ratio = 1.53 (95% confidence interval = [1.22, 1.91]) and 1.47 (95% confidence interval = [1.16, 1.86]).

CONCLUSION

The mode of delivery has a significant effect on the occurrence of mild postpartum depression. Women who give birth by cesarean section, especially who give birth by emergency cesarean section, are at a higher risk of mild postpartum depression. We should carefully monitor the progress of postpartum mental disorders in women who delivered by cesarean section and make it possible for women to have a quick access to mental healthcare.

Anxiety and depression in women hospitalized due to high-risk pregnancy: An integrative quantitative and qualitative study

Literature has shown that hospitalized women with high-risk pregnancy tend to develop anxious and depressive symptoms. Research has used quantitative or qualitative methods. By integrating both quantitative and qualitative methods, this study aims to analyze: a) the level of depression, anxiety, and pregnancy-related anxiety in a group of women hospitalized with high-risk pregnancy (hospitalized high-risk) compared with a group of non-hospitalized women with low-risk pregnancy; b) the content of hospitalization-related emotions in a high-risk group. A cross-sectional study was conducted on 30 hospitalized high-risk pregnant women and 32 women with low-risk pregnancy. Participants completed the Edinburgh Postnatal Depression Scale, Hospital Anxiety and Depression Scale (Anxiety), and Pregnancy Related Anxiety Questionnaire. The hospitalized high-risk group also completed open-ended questions about emotions experienced during hospitalization. Univariate Analysis of Covariance showed that the hospitalized high-risk group reported higher general anxiety and depression than the low-risk pregnancy group. Low-risk group reported higher level of concerns about own appearance than high-risk group. Narratives showed that the anxious and depressive symptoms of hospitalized women are related to the loneliness of being away from family. Despite attempts to understand hospitalization, they express concerns about pregnancy. Psychological support for hospitalized pregnant women should be provided to facilitate the communication of emotions that leads women to elaborate the experience of hospitalization to better adapt and cope with the critical condition.

Impact of Endocrine-Disrupting Chemicals in Breast Milk on Postpartum Depression in Korean Mothers

Previous human and animal studies have reported an association between endocrine-disrupting chemicals (EDCs) and anxiety/depression. This study aimed to determine how the concentrations of phthalate metabolites, bisphenol A, triclosan, and parabens in breast milk are associated with the risk of developing postpartum depression (PPD) in Korean mothers. We recruited 221 mothers who were receiving lactation coaching at breastfeeding clinics between July and September 2018. The breast milk samples were collected along with responses to the Edinburgh Postnatal Depression Scale. The multivariable logistic regression results revealed that the phthalate, bisphenol A, parabens, and triclosan levels in the breast milk were not significantly associated with the risk of PPD. This study was the first attempt to analyze the association between the levels of EDCs in breast milk and the risk of PPD. Considering that PPD is a condition that affects not only the women diagnosed with it, but also their children and families, the results of this study may have great relevance to populations in environmentally sensitive periods.
