Risk factors for depressive symptoms during pregnancy: a systematic review

Comparative assessment of Patient Health Questionnaire-9 and Edinburgh Postnatal Depression Scale for screening antenatal depression among Chinese pregnant women

BACKGROUND

The Patient Health Questionnaire-9 (PHQ-9) and Edinburgh Postnatal Depression Scale (EPDS) are commonly used for assessing antenatal depression in China. However, clear guidelines for their application are lacking in China, leading to inconsistencies in prenatal mental health care. This study compares the psychometric properties of these scales to improve early detection and intervention strategies for antenatal depression.

METHODS

The cross-sectional study included 44,220 women receiving prenatal care from January 1, 2020, to January 31, 2024. All the participants underwent a psychological screening during their maternity check-ups at the Shenzhen Baoan Women's and Children's Hospital, China. We evaluated the reliability, construct validity, and concurrent validity of the two scales using internal consistency indices, factor structures, correlations, and Cohen's kappa.

RESULTS

Both the PHQ-9 (Cronbach's α = 0.800) and EPDS (α = 0.783) demonstrated good internal consistency. The correlation between PHQ-9 and EPDS scores was moderate (ρ = 0.61). Exploratory factor analysis (EFA) revealed a two-factor structure for each scale. When combining all items from both scales, EFA identified four factors: "somatic symptoms," "negative cognitive bias and suicidal ideation," "anxiety and depression," and "anhedonia." The agreement was generally fair across various cutoff scores, with the highest Cohen's kappa being 0.493.

CONCLUSIONS

Both the EPDS and PHQ-9 exhibit strong internal consistency in screening for antenatal depression in China. While the EPDS emphasizes "depression and anxiety," the PHQ-9 focuses on "somatic symptoms," suggesting that combining the two may improve detection. Adjusting EPDS cutoff scores and incorporating the PHQ-9 could further enhance screening accuracy.

The efficacy of antenatal Cognitive Behavioural Therapy for antenatal and postnatal depression: A PRISMA based systematic review and meta-analysis

BACKGROUND

Considerable research has assessed the effectiveness of Cognitive Behavioural Therapy (CBT) for perinatal depression, however limited attention has been paid to its effectiveness when delivered during pregnancy. The primary aim of this review was to review evidence of the efficacy of CBT interventions delivered antenatally to treat symptoms of depression in women during the antenatal and postnatal periods. The review's secondary aim was to evaluate potential moderators of treatment outcome.

METHODS

Electronic Databases; CINAHL, PsycINFO, Medline, Scopus, and Web of Science were searched for studies that employed CBT in response to symptoms of depression in pregnant women. Randomized control trials were included if they compared outcomes for pregnant women with outcomes of inactive controls. A systematic review and meta-analysis was conducted on n = 12 eligible studies.

RESULTS

CBT yielded statistically significant, within and between groups' effects on depressive symptoms during the antenatal period. CBT delivered at that time also yielded smaller yet statistically significant within and between groups' effects on depressive symptoms experienced postnatally. CBT was found to be more effective for women of greater age, higher number of weeks gestation, or who were multiparous. The facilitator of treatment, delivery mode, the assessment measures used to evaluate treatment outcome, and symptom severity also moderated treatment outcome.

LIMITATIONS

Significant publication bias and heterogeneity were evident across studies indicating a need to focus future research.

CONCLUSIONS

Overall, findings support the use of CBT delivered antenatally to reduce depression experienced during, and following, pregnancy.

Effects of the Energy-Adjusted Dietary Inflammation Index During Pregnancy on Prenatal Depression: The Mediating Effect of Sleep Quality

(1) Background: Prenatal depression is prevalent and can adversely affect maternal and infant health. This study aimed to analyze the relationship between the energy-adjusted dietary inflammatory index (E-DII) and prenatal depression, as well as to explore the mediating effect of sleep quality. (2) Methods: In this cross-sectional study, a total of 749 pregnant women were enrolled. The E-DII scores were evaluated using semi-quantitative Food Frequency Questionnaires (FFQ); the Edinburgh Postpartum Depression Scale (EPDS) was used to measure depression levels; and the Pittsburgh Sleep Quality Index (PSQI) to evaluate the sleep quality of pregnant women. Binary logistic regression analysis was employed to analyze the relationships of E-DII with prenatal depression, of E-DII with sleep quality, and of sleep quality with prenatal depression. The bootstrap approach was employed to investigate the mediating effect of sleep quality. (3) Results: Findings indicated that a higher E-DII score was significantly associated with an increased risk of prenatal depression compared to the lowest score, and this association still existed after adjusting for sleep quality. In addition, the lowest E-DII score was also associated with a lower risk of poor sleep quality. Sleep quality played a partial mediating role in the association between E-DII and prenatal depression, and the proportion of the mediation effect relative to the total effect was 34.30%. (4) Conclusions: Sleep quality partially mediated the association between E-DII and prenatal depression. Close monitoring and proactive improvement of sleep quality among pregnant women following a pro-inflammatory diet may help reduce the risk of developing prenatal depression.

Association Between Maternal Sleep Health and Mental Health: Moderating Role of Family Function

OBJECTIVE

Pregnancy, as a complex physiological process, significantly alters maternal sleep patterns, which are closely associated with various maternal health outcomes. This study explored the association between maternal sleep health and anxiety/depression symptoms and whether this association differed by family function.

METHODS

A cross-sectional survey was conducted among pregnant women attending obstetrics departments at two hospitals in Nanjing, China. The Sleep Health Index, Family APGAR, and Patient Health Questionnaire-4 were administered to evaluate sleep health, family function, and anxiety and depression symptoms of pregnant women in late pregnancy, respectively. Multiple linear and logistic regressions were applied, with the moderation effect of the family function being assessed by adding interaction terms in the models.

RESULTS

A total of 199 pregnant women in late pregnancy completed the survey. The average age and gestational age were 30.95 years (SD = 3.38, Range: 19-42) and 36.39 weeks (SD = 2.52, Range: 28-40), respectively. The scores of sleep health, anxiety, depression, and family function were 84.37 ± 10.61, 0.00 (0.00, 2.00), 0.00 (0.00, 1.00), and 8.79 ± 1.82, respectively. Results showed that better sleep health was associated with lower scores of anxiety (β=-0.03, p < .001) and depression (β=-0.04, p < .001) symptoms and lower odds of anxiety (adjusted odds ratio, aOR = 0.92, p = .006) and depression (aOR = 0.93, p = .003) symptoms. Family function significantly moderated the relationship between sleep health and scores of anxiety (β = 0.01, p = .013) and depression (β = 0.01, p < .001) symptoms.

CONCLUSION

Good sleep health in late pregnancy is associated with reduced anxiety and depression symptoms, with a stronger association found in pregnant women with weaker family function.

The impact of relationship factors on antenatal depression in the context of the COVID-19 pandemic

BACKGROUND

Antenatal depression is the most prevalent pregnancy-associated mental health disorder. Previous studies have identified several risk factors for antenatal depression, including partner support. However, during the COVID-19 pandemic, many relationship dynamics changed. This study examined the extent to which relationship factors had an impact on antenatal depression in comparison with other well-researched factors in the context of the pandemic.

METHODS

A secondary analysis was conducted using data from the P3 Cohort in Calgary, a longitudinal cohort study based in Alberta, Canada. Pregnant people (n = 872) completed self-report questionnaires and validated scales about sociodemographic, psychological, and relationship characteristics. Antenatal depression was assessed using the Edinburgh Postnatal Depression Scale (EPDS). Logistic regression was used to assess the impact of reported characteristics on antenatal depression. Tests of model fit were used to examine whether the inclusion of variables related to relationship quality improved model fit after accounting for other known risk factors.

RESULTS

Overall, 18.23% of participants experienced antenatal depression. Relationship factors including relationship unhappiness (OR = 1.98 [95% CI: 1.06-3.69]), having an upsetting partner (OR = 2.00 [95% CI: 1.17-3.40]), and having a lower quality of relationships with close friends and family (OR = 1.76 [95% CI: 1.14-2.73]) were associated with antenatal depression; however, inclusion of these relationship factors did not improve model fit after accounting for other known predictors.

CONCLUSION

Overall, relationship factors were not associated with antenatal depression during the pandemic after accounting for other known risk factors. Stress and anxiety caused by the pandemic may have overshadowed the impact of relationship factors, or relationship factors may have contributed to higher levels of stress and anxiety more generally within our sample.

Risk of postpartum depression in women with allergic disorders: A nationwide cohort study involving 1,017,507 women

BACKGROUND

Allergic symptoms and depression are prevalent ailments in childbearing age women. This study assessed the risk of maternal postpartum depression (PPD) associated with prenatal allergic disorders.

METHODS

From 1,017,507 eligible women of 20-49 years old with singleton live births and 20-week or more gestational age in the birth registry of Taiwan, from 2011 to 2020, we identified cohorts with and without allergic disorders matched by propensity score in the size of 457,826. Cumulative incident PPDs in one year after births were assessed from insurance claims data. Odds ratios (OR) of PPD were measured by each allergic type and multiple types, comparing with the controls.

RESULTS

With an overall cumulative PPD incidence 1.25-fold higher in the allergic cohort than in the controls (0.69 % versus 0.55 %), the rate was the highest in women with asthma: 0.94 % with an adjusted OR of 1.71 (95 % CI = 1.49-1.95), followed by those with allergic rhinitis, allergic conjunctivitis and atopic dermatitis. The rate increased from 0.65 % for those with one allergic disorder to 1.06 % for those with 4 or 5 disorders, and the corresponding adjusted OR increased from 1.17 (95 % CI = 1.10-1.24) to 1.92 (95 % CI = 1.36-2.69).

LIMITATION

The claims data lack detailed information on socio-demographic status, lifestyle, laboratory result, physical activity, and family medical history.

CONCLUSIONS

Women with prenatal allergic disorder(s) are at an increased risk of PPD in addition to the impact of pregnancy. Prompt and efficient intervention for PPD prevention is needed for women with allergic disorders, particularly for those with asthma and multiple disorders.

Prevalence and associated factors of psychological distress among caregivers of children with malnutrition: a cross‑sectional study

BACKGROUND

Malnutrition is a major child health problem in developing countries, contributing to 53% of child deaths annually. Psychological distress is an emotional and behavioral condition that causes significant suffering and interferes with a person's daily life. Caregivers' psychological distress can negatively impact a child's development. Studies have shown that psychological distress has an impact on infant growth and nutritional status. However, evidence regarding the relationship between psychological distress and child malnutrition is scarce.

OBJECTIVES

The aim of this study was to determine the prevalence of psychological distress among caregivers of malnourished children and to identify factors associated with this.

METHODS

This was a cross-sectional study was conducted and 409 caregivers participated. Outcome variable was assessed using Kessler Psychological Distress Scale (K-10).The collected data were analyzed using SPSS version 25. Bivariable and multivariable logistic analysis was conducted to identify factors associated with Psychological distress and Variables with P-value < 0.05 were considered to have significant association with 95% confidence interval.

RESULTS

The prevalence Psychological distress among caregivers of malnourished children was 42.5%. Unemployment (AOR = 3.39, 95% CI: 2.14-9.11), poor socioeconomic status (AOR = 3.91, 95% CI: 1.46-9.34), low child feeding practices (AOR = 2.18, 95% CI: 1.12-4.21), poor social support (AOR = 4.44, 95% CI: 1.75-11.29), physical and emotional abuse (AOR = 3.37, 95% CI: 1.36-8.35), and child underweight (AOR = 4.36, 95% CI: 3.94-8.36) were factors statically significant associated with psychological distress.

CONCLUSION

Caregivers of malnourished children experienced high psychological distress linked to unemployment, poverty, poor feeding practices, poor social support, both physical and emotional abuse and child underweight. Therefore, strategies should focus on improving employment, strengthening social support, promoting proper child feeding, raising economic status, preventing abuse, and combating underweight to reduce caregiver psychological distress.

Maternal Antenatal Depression Is Associated With Metabolic Alterations That Predict Birth Outcomes and Child Neurodevelopment and Mental Health

BACKGROUND

Evidence regarding metabolic alterations associated with maternal antenatal depression (AD) is limited, and their role as potential biomarkers that improve the prediction of AD and adverse childbirth, neurodevelopmental, and mental health outcomes remains unexplored.

METHODS

In a cohort of 331 mother-child dyads, we studied associations between AD (a history of medical register diagnoses and/or a Center for Epidemiological Studies Depression Scale score during pregnancy ≥ 20) and 95 metabolic measures analyzed 3 times during pregnancy. We tested whether the AD-related metabolic measures increased variance explained in AD over its risk factors and in childbirth, neurodevelopmental, and mental health outcomes over AD. We replicated the findings in a cohort of 416 mother-child dyads.

RESULTS

Elastic net regression identified 15 metabolic measures that collectively explained 25% (p < .0001) of the variance in AD, including amino and fatty acids, glucose, inflammation, and lipids. These metabolic measures increased the variance explained in AD over its risk factors (32.3%, p < .0001 vs. 12.6%, p = .004) and in child gestational age (9.0%, p < .0001 vs. 0.7%, p = .34), birth weight (9.0%, p = .03 vs. 0.7%, p = .33), developmental milestones at the age of 2.3 to 5.7 years (21.0%, p = .002 vs. 11.6%, p < .001), and any mental or behavioral disorder by the age of 13.1 to 16.8 years (25.2%, p = .03 vs. 5.0%, p = .11) over AD, child sex, and age. These findings were replicated in the independent cohort.

CONCLUSIONS

AD was associated with alterations in 15 metabolic measures, which collectively improved the prediction of AD over its risk factors and birth, neurodevelopmental, and mental health outcomes in children over AD. These metabolic measures may become biomarkers that can be used to identify at-risk mothers and children for personalized interventions.

Neuropsychological performance in women at risk of postpartum depression and postpartum psychosis

PURPOSE

While neuropsychological deficits are commonly observed in affective and psychotic disorders, this remains unexplored in these disorders when they occur during pregnancy and the postpartum period.

METHODS

A neuropsychological test battery was administered to women defined at risk of postpartum depression (PD, N = 53) because having either a current or past diagnosis of major depressive disorder, women at risk of postpartum psychosis (PP, N = 43) because of a diagnosis of bipolar disorder or schizoaffective disorder and/or a previous episode of PP and women not at risk (NR, N = 48) in the third trimester of pregnancy. Generalized and specific cognitive abilities were compared between groups.

RESULTS

Women at risk of PP presented worse executive functions and processing speed compared to NR and worse performance compared to women at risk of PD across all cognitive domains. In addition, women at risk of PP who developed a psychiatric relapse in the first four weeks post-partum showed worse verbal learning and memory, visual memory, executive functions and processing speed in pregnancy compared to NR, whereas women at risk of PP who remained well presented neuropsychological performance that was intermediate between that of the women NR and those at risk of PP who developed symptoms. There were no differences in performance between women at risk of PD and the NR women, even if 31 women at risk of PD presented depressive symptoms at the time of cognitive assessment.

CONCLUSIONS

Our findings in women at risk of PP align with neuropsychological findings in individuals with, or at risk of psychosis unrelated to pregnancy. In addition, initial evidence that women at risk of PP who develop a psychiatric relapse in the postpartum show a particularly poor neuropsychological performance in pregnancy suggests that this could be considered part of a phenotype for the disease and help guiding future preventive strategies in this clinical population. In women at risk of PD, the presence of depressive symptoms did not influence cognitive performance.

Antenatal depression among pregnant women in Ethiopia: An umbrella review

INTRODUCTION

Antenatal depression, ranging from mild to severe, is influenced by hormonal changes during pregnancy and childbearing years, making it a significant public health issue. Antenatal depression, with its far-reaching effects on mothers, infants, and children, continues to be a significant public health issue in developing countries such as Ethiopia. Research on antenatal depression in Ethiopia has produced varied results. Although previous systematic reviews and meta-analyses studies have addressed this topic, a comprehensive summary of existing reviews has not been available. Therefore, this umbrella review aims to consolidate the findings on antenatal depression and associated factors among pregnant women in Ethiopia.

METHODS

This review included five systematic reviews and meta-analyses from various databases, including PubMed, PsycINFO, Research4life, CINHALE and Science Direct. Only reviews published between January 1, 2010, and July 30, 2024, were considered. The search, conducted from August 5 to 15, 2024, used CoCoPop questions and included only English-language reviews. Study quality was assessed with the AMSTAR tool, and data extraction and analysis were performed using Microsoft Excel 2016 and STATA 14.0. The I2 and Cochran's Q tests were used to assess heterogeneity. Pooled effect sizes were calculated based on the pooled prevalence of antenatal depression and odds ratios for associated factors, with a 95% confidence interval indicating statistical significance.

RESULTS

This umbrella review encompassed 50 primary studies from five systematic reviews and meta-analyses, involving a total of 25,233 pregnant women. The pooled prevalence of antenatal depression in Ethiopia was found to be 24.60% (95% CI: 22.46-26.73). Significant associations were identified between antenatal depression and several factors: unplanned pregnancy (POR = 2.29; 95% CI: 1.75, 2.82), poor social support (POR = 2.10; 95% CI: 1.37, 2.84), history of abortion (POR = 2.49; 95% CI: 1.64, 3.34), history of depression (POR = 3.57; 95% CI: 2.43, 4.71), and history of obstetric complications (POR = 2.94; 95% CI: 1.61, 4.28).

CONCLUSIONS

The significant prevalence of antenatal depression (24.60%) among pregnant women in Ethiopia is closely linked to factors such as unplanned pregnancy, poor social support, history of abortion, previous depression, and obstetric complications. To tackle this issue, it is recommended to enhance social support networks, increase access to family planning services to minimize unplanned pregnancies, conduct regular mental health screenings, and incorporate mental health services into antenatal care.

Maternal Well-Being and Child Appetitive Traits at 5 Years Old: Findings from the ROLO Longitudinal Birth Cohort Study

Background: Maternal depression has been linked with increased risk of childhood obesity. Furthermore, maternal negative affectivity in early childhood has been associated with food fussiness. We explored the relationship between longitudinal maternal well-being mid-pregnancy, at 2 years and 5 years postpartum and children's appetitive traits at 5 years of age. Methods: This is a secondary analysis of the ROLO (randomized control trial of low glycemic diet in pregnancy) longitudinal birth cohort study including pregnancy (n = 279), 2 years (n = 168), and 5 years (n = 295) postpartum. Maternal well-being was measured using the World Health Organization-Five Well-Being Index. Children's appetitive traits were measured at 5 years of age using the Children's Eating Behavior Questionnaire. Bivariate correlation and then linear regression, adjusted for potential confounders, were used to determine relationships between maternal well-being at each timepoint and offspring's appetitive traits at 5 years old. Results: Mean maternal well-being was higher at 5 years postpartum (63.3%) than mid-pregnancy (58.2%) or at 2 years postpartum (61.0%) (p = 0.001). No relationships were observed between maternal well-being mid-pregnancy and child's appetitive traits at 5 years. In adjusted regression, at 2 years postpartum, maternal well-being was negatively associated with "Emotional Overeating" (B = -0.029, p = 0.024), "Satiety Responsiveness" (B = -0.040, p = 0.014), "Slowness Eating" (B = -0.072, p = <0.001), and "Emotional Undereating" (B = -0.054, p = 0.010) and positively associated with "Enjoyment of Food" (B = 0.050, p = 0.007). Maternal well-being at 5 years postpartum was negatively associated with "Satiety Responsiveness" (B = -0.025, p = 0.033) and "Slowness Eating" (B = -0.031, p = 0.024). Conclusion: Maternal well-being in early childhood may influence children's appetitive traits; however, further research is required to fully explore this relationship.

Measuring psychological well-being in a danish pregnancy cohort using the self-reported WHO-5 index

BACKGROUND

Reduced well-being and depressive episodes frequently complicate pregnancy and can result in serious adverse outcomes for both mother and infant if left untreated. This study aimed to assess the psychometric validity of the 5-item World Health Organization index (WHO-5), and to evaluate if the WHO-5 index can serve as a proxy for two items of core depressive symptoms from the Major Depression Inventory (MDI), identified as MDI-2. Additionally, the paper aimed to assess well-being and detect risk factors of reduced well-being using the WHO-5 index.

METHODS

Using the WHO-5 index, this study analyzed the psychological well-being of a population of 37,129 women in their first trimester of pregnancy. The psychometric validity of the WHO-5 index was evaluated using confirmatory factor analysis and item response theory. Furthermore, cut-off scores of the WHO-5 index previously associated with mental distress, ≤ 50 and ≤ 28, were evaluated in terms of sensitivity, specificity, and positive- and negative predictive values compared to the MDI-2 in a subsample of n = 1001 women.

RESULTS

Lower mean score on the WHO-5 index was seen among pregnant women ≤ 25 years old, with lower educational level, who were unemployed, nulliparous, did not understand Danish language, were not cohabitating, were smokers, and women who did not exercise prior to pregnancy. The WHO-5 index was found to be a valid psychometric instrument, however, scores could not be pooled or compared across women who understood Danish and women who did not understand Danish. The sensitivity and specificity of cut-off score of ≤ 50 on the WHO-5 index with a for predicting the presence of one core symptom from the MDI-2 was 0.81 and 0.82, respectively, while the sensitivity and specificity using a cut-off of ≤ 28 was 0.32 and 0.98, respectively.

CONCLUSIONS

The WHO-5 index had high degree of acceptability and identified well-known risk factors of mental distress in a pregnant population. The WHO-5 index was found to be a valid psychometric instrument in pregnancy, however, our analysis indicated low predictive value of the investigated cut-off scores on the WHO-5 index in identification of MDI-2 core symptoms.

Associations between mental health conditions in pregnancy and maternal socioeconomic status: a population-based retrospective cohort study in Ontario, Canada

BACKGROUND

The World Health Organization has recognized maternal mental illness as an emerging issue. Previous studies have indicated that maternal mental illness is associated with socioeconomic status (SES). However, there is a lack of research concerning the mental health of pregnant people with low SES in Ontario, Canada. In this study, we examined associations between mental health conditions during pregnancy and two SES indicators: the pregnant person's residential neighbourhood income and education level.

METHODS

A population-based retrospective cohort study was conducted, consisting of all singleton pregnancies resulting in stillbirths or live births in Ontario hospitals from April 1, 2012, to March 31, 2021. Data were linked from the BORN Information System database, Canadian Institute for Health Information Discharge Abstract Database, and Canadian Census. Poisson regression with robust error variance models was performed to estimate the relative risks of anxiety, depression, anxiety and/or depression, or any mental health condition during pregnancy, by SES indicator. We adjusted for maternal age, obesity status in pre-pregnancy, certain pre-existing maternal health conditions, substance use during pregnancy, race, and rural or urban residence.

RESULTS

Within the cohort (n = 1,202,292), 10.5% (126,076) and 8.1% (97,135) of pregnant individuals experienced anxiety and depression, respectively, and 15.8% (189,616) had at least one mental health condition during pregnancy. The trend test (p < 0.0001) showed a significant downward trend in the total rates of mental health conditions by increasing SES quintiles. Pregnant individuals in the lowest neighbourhood income quintile tended to have a higher risk of anxiety (aRR: 1.24, 95%CI: 1.22-1.27), depression (aRR: 1.56, 95%CI: 1.52-1.59), anxiety and/or depression (aRR: 1.13, 95%CI: 1.11-1.15), or any mental health condition (aRR: 1.18, 95%CI: 1.16-1.19). Similarly, pregnant people living in the lowest education level neighbourhoods had higher likelihoods of anxiety (aRR: 1.66, 95%CI: 1.62-1.69), depression (aRR: 2.09, 95%CI: 2.04-2.14), anxiety and/or depression (aRR: 1.42, 95%CI: 1.39-1.44), and any mental health condition (aRR: 1.41, 95%CI: 1.38-1.43).

CONCLUSIONS

Despite a universal healthcare system, the variations in mental health prevalence and risk during pregnancy based on SES suggest health inequity in Ontario, Canada. Future studies are needed to examine the mechanisms of this health inequity to guide policy makers in reducing disparities in Ontario.

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

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

General practitioners' barriers to cross-sectoral collaboration on pregnant women with vulnerabilities: a cross-sectional survey in Danish general practice

BACKGROUND

Pregnancy vulnerability contributes to poor perinatal mental health. Proper cross-sectoral collaboration may mitigate perinatal mental health problems. General practitioners (GPs) often face barriers when assessing pregnancy vulnerability, but little is known about GPs' perceived barriers to the cross-sectoral collaboration on vulnerable pregnant women.

OBJECTIVE

To explore GPs' barriers to cross-sectoral collaboration on pregnant women with vulnerabilities, and how barriers are associated with the organization of antenatal care (ANC) and general practice characteristics.

DESIGN, SETTING AND SUBJECTS

A cross-sectional questionnaire study among Danish GPs (n = 3465).

MAIN OUTCOME MEASURES

Descriptive statistics according to the Theoretical Domains Framework describes the barriers to collaboration. Analytical statistics with ordered logistic regression models demonstrate associations between selected barriers (the main outcome measures) and organization of ANC, GP and practice, characteristics.

RESULTS

A total of 760 GPs (22%) participated. Perceived GP barriers to collaboration were lacking knowledge of ANC levels relevant to vulnerable pregnant women, insufficient information on vulnerability indicators from collaborating parties, heavy workload and insufficient remuneration for collaborative meetings. Being young were associated with insufficient GP knowledge of ANC levels. Old age was associated with less likelihood of experiencing heavy workload as a barrier.

CONCLUSIONS

Barriers to collaboration on vulnerable pregnant women were associated with some GP-organizational characteristics including low experience in collaborating with partners in ANC, and GP characteristics, such as age. Reducing general practice workload, e.g. by reorganizing priority areas, releasing more time to vulnerable patients, and improving cross-sectoral information sharing on vulnerability might improve collaboration on vulnerable pregnant women.

Pathways to depressive symptoms in Chinese pregnant women and their influence on delivery approach: a qualitative comparative analysis

The aim of this study was to apply complexity theory to explain and understand how risk factors combined in complex ways, eventually leading to a high prevalence of depressive symptoms among pregnant women. We also aimed to evaluate whether depressive symptoms affected delivery approach. The study had a longitudinal design and was conducted between May and September 2017. A total of 481 pregnant women were recruited to participate and completed closed-end surveys at two distinct times: during prenatal care at the hospital after 26 weeks of pregnancy and 1 to 4 weeks after delivery. This study identified eleven different pathways that led to an increase in depressive symptoms. Each pathway differentiated the effects of different influencing factors. Among the 481 pregnant women, 128 (26.6%) had cesarean deliveries without medical indications. Although depressive symptoms could affect delivery approach, it was not the most important factor. Surprisingly, the first production emerged as the key factor determining delivery mode. This study was innovative in that it examined which factors and which combinations of factors were necessary for the development of depressive symptoms. Additionally, this study provided a better understanding of the mechanisms underlying the choice of cesarean section without medical indications.

Predicting first time depression onset in pregnancy: applying machine learning methods to patient-reported data

PURPOSE

To develop a machine learning algorithm, using patient-reported data from early pregnancy, to predict later onset of first time moderate-to-severe depression.

METHODS

A sample of 944 U.S. patient participants from a larger longitudinal observational cohortused a prenatal support mobile app from September 2019 to April 2022. Participants self-reported clinical and social risk factors during first trimester initiation of app use and completed voluntary depression screenings in each trimester. Several machine learning algorithms were applied to self-reported data, including a novel algorithm for causal discovery. Training and test datasets were built from a randomized 80/20 data split. Models were evaluated on their predictive accuracy and their simplicity (i.e., fewest variables required for prediction).

RESULTS

Among participants, 78% identified as white with an average age of 30 [IQR 26-34]; 61% had income ≥ $50,000; 70% had a college degree or higher; and 49% were nulliparous. All models accurately predicted first time moderate-severe depression using first trimester baseline data (AUC 0.74-0.89, sensitivity 0.35-0.81, specificity 0.78-0.95). Several predictors were common across models, including anxiety history, partnered status, psychosocial factors, and pregnancy-specific stressors. The optimal model used only 14 (26%) of the possible variables and had excellent accuracy (AUC = 0.89, sensitivity = 0.81, specificity = 0.83). When food insecurity reports were included among a subset of participants, demographics, including race and income, dropped out and the model became more accurate (AUC = 0.93) and simpler (9 variables).

CONCLUSION

A relatively small amount of self-report data produced a highly predictive model of first time depression among pregnant individuals.

Depressive symptoms during pregnancy and postpartum: associations with mode of conception and demographic and obstetric factors

An increasing number of women are conceiving through assisted reproductive technology; however, few studies have investigated their mental health after successful conception. This study investigated the changes in depressive symptoms in women using assisted reproductive technology and the association between the mode of conception and perinatal depressive symptoms. A longitudinal observational study was conducted from 2015 to 2019, 542 pregnant women completed questionnaires on depressive symptoms at eight timepoints during the prepregnancy, pregnancy and first-year postpartum periods. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. A generalized estimating equation regression model was employed for repeated measures. In the assisted reproductive technology group, depressive symptoms were more prevalent during early pregnancy and at 1 month postpartum than before pregnancy, and more prevalent before pregnancy and at 1 month after childbirth than in the spontaneous conception group. No significant association was identified between the mode of conception and depressive symptoms during the antenatal or postnatal period. The lack of full-time employment and prepregnancy depressive symptoms were associated with antenatal depressive symptoms. Primipara status and depressive symptoms during prepregnancy and pregnancy were associated with depressive symptoms during the first-year postpartum. Assisted reproductive technology was not a risk factor for depressive symptoms during the pregnancy and postpartum periods, whereas primipara status, lack of full-time employment and prepregnancy depressive symptoms were negative predictors. Therefore, targeted mental health interventions should address these specific factors to effectively support maternal mental health.

Association between antepartum admission and postpartum depressive symptoms

BACKGROUND

Postpartum depression affects 14% of pregnant individuals and is a leading cause of preventable maternal mortality. Complications of pregnancy, such as preterm labor or pre-eclampsia, may require hospitalization for close monitoring and management. The impact of an antenatal hospitalization during pregnancy on postnatal depression remains understudied.

OBJECTIVE

To evaluate whether hospital admission during pregnancy was associated with postpartum depressive symptoms in individuals who were enrolled in a collaborative care model and to evaluate whether enrollment in the collaborative care model during pregnancy mitigated this association.

STUDY DESIGN

This secondary analysis of a prospective cohort study included perinatal people enrolled in a collaborative care model at a quaternary academic center between 2017 and 2021. The primary outcome was presence of moderately severe or severe postpartum depressive symptoms at 6 weeks postpartum defined as a score of 15 or greater on a PHQ-9. The prevalence of symptoms of this severity was compared between those who experienced an antepartum hospitalization and those who did not using bivariable and multivariable analyses. A Breslow Day test was used to evaluate whether any observed association between antepartum hospitalization and postpartum depressive symptoms differed based on timing of enrollment in the collaborative care model.

RESULTS

During the study period, 1897 individuals met inclusion criteria. Of these, 162 (8.5%) were admitted to the hospital during pregnancy. Of those with an antepartum hospitalization, 20 (12.4%) developed moderately severe to severe postpartum depressive symptoms compared to 136 (7.8%) of those who were not hospitalized (p=.046). After adjustment for confounders identified through use of a directed acyclic graph, this difference did not persist in multivariable analysis (aOR 1.55, 95% CI [0.87-2.75]). A Breslow Day test demonstrated heterogeneity across enrollment timing, so subgroup analyses were performed for those enrolled during pregnancy (n=930) vs postpartum (n=967). Hospital admission was associated with higher rates of moderately severe to severe postpartum depressive symptoms in those enrolled in the collaborative care model postpartum (19.7% vs 10.6%, p=.015, aOR 2.25, 95% CI [1.07-4.71]), but not those enrolled antenatally (5.8% vs 5.0%, p=.735, aOR 1.09, 95% CI [0.38-3.19]).

CONCLUSION

Antepartum hospital admission was associated with higher rates of moderately severe to severe depressive symptoms. This association did not exist among individuals enrolled in collaborative care model during pregnancy, suggesting a potential protective effect afforded by engagement in a mental health support programming.

Stability and change in maternal wellbeing and illbeing from pregnancy to three years postpartum

PURPOSE

Motherhood affects women's mental health, encompassing aspects of both wellbeing and illbeing. This study investigated stability and change in wellbeing (i.e., relationship satisfaction and positive affect) and illbeing (i.e., depressive and anxiety symptoms) from pregnancy to three years postpartum. We further investigated the mutual and dynamic relations between these constructs over time and the role of genetic propensities in their time-invariant stability.

DATA AND METHODS

This four-wave longitudinal study included 83,124 women from the Norwegian Mother, Father, and Child Cohort Study (MoBa) linked to the Medical Birth Registry of Norway. Data were collected during pregnancy (30 weeks) and at 6, 18 and 36 months postpartum. Wellbeing and illbeing were based on the Relationship Satisfaction Scale, the Differential Emotions Scale and Hopkins Symptoms Checklist-8. Genetics were measured by the wellbeing spectrum polygenic index. Analyses were based on random intercept cross-lagged panel models using R.

RESULTS

All four outcomes showed high stability and were mutually interconnected over time, with abundant cross-lagged predictions. The period of greatest instability was from pregnancy to 6 months postpartum, followed by increasing stability. Prenatal relationship satisfaction played a crucial role in maternal mental health postpartum. Women's genetic propensity to wellbeing contributed to time-invariant stability of all four constructs.

CONCLUSION

Understanding the mutual relationship between different aspects of wellbeing and illbeing allows for identifying potential targets for health promotion interventions. Time-invariant stability was partially explained by genetics. Maternal wellbeing and illbeing develop in an interdependent way from pregnancy to 36 months postpartum.

"Association between perinatal mood disorders of parents and child health outcomes"

PURPOSE

Perinatal mood disorders affect both parents, impacting their children negatively. Little is known on the association between parental perinatal mood disorders and pediatric outcomes in Japan considering relevant covariates. Our objective was to investigate the association between paternal and maternal perinatal mood disorders and adverse physical and psychological child outcomes by the age of 36 months, adjusting for covariates such as the child's sex, age of parent at child's birth, perinatal mood disorders of the other parent, and perinatal antidepressant use.

METHODS

We identified parents in the JMDC Claims Database in Japan from 2012 to 2020. Perinatal mood disorders were defined using International Classification of Diseases, 10th codes for mood disorders during the perinatal period combined with psychiatric treatment codes. We evaluated the association between parental perinatal mood disorders and pediatric adverse outcomes by the age of 36 months using Cox proportional hazard models adjusted for the covariates.

RESULTS

Of the 116,423 father-mother-child triads, 2.8% of fathers and 2.3% of mothers had perinatal mood disorders. Paternal perinatal mood disorders were not significantly associated with adverse child outcomes. After adjusting for paternal perinatal mood disorders and antidepressant use, maternal perinatal mood disorders were associated with delayed motor development, language development disorders, autism spectrum disorders, and behavioral and emotional disorders (adjusted hazard ratio [95% confidence interval]: 1.65 [1.01-2.69], 2.26 [1.36-3.75], 4.16 [2.64-6.55], and 6.12 [1.35-27.81], respectively).

CONCLUSIONS

Paternal perinatal mood disorders were not associated with adverse child outcomes in this population. Maternal perinatal mood disorders were associated with multiple child outcomes.

Association of trajectories and cumulative exposure of antenatal depression with high birth weight

BACKGROUND

Inconsistent associations between antenatal depression and fetal birth weight were reported previously, and little is known about the dynamic changes and long-term cumulative effect of antenatal depression during pregnancy.

METHODS

Participants were from the Tongji-Huaxi-Shuangliu Birth Cohort. Depressive symptoms were measured using the Edinburgh Postnatal Depression Scale in early, middle, and late pregnancy respectively. Trajectories of antenatal depression were assessed using the latent class mixed model. The percentage of days with depression (PDD) and frequency of antenatal depression were measured to assess the cumulative exposure. Multivariable logistic regression models were used to evaluate the associations of antenatal depression with macrosomia and large for gestational age (LGA).

RESULTS

We identified four distinct trajectories, including the low stable group (n = 1,327, 27.99 %), the moderate stable group (n = 2,610, 55.05 %), the peak group (n = 407, 8.58 %), and the valley group (n = 397, 8.37 %). Compared with the low stable group, the valley group showed a higher risk of macrosomia (OR, 1.98; 95 % CI, 1.17, 3.38) and LGA (OR, 1.44; 95 % CI, 1.002, 2.09); the peak group showed a higher risk of LGA (OR, 1.52; 95 % CI, 1.07, 2.16), but the association was not significant for macrosomia (OR, 1.47; 95 % CI, 0.85, 2.55). Consistently, cumulative antenatal depression was also positively associated with the risks of macrosomia and LGA.

LIMITATION

The antenatal depression was self-reported using a screening scale and information bias could not be ruled out.

CONCLUSION

Certain trajectories and cumulative exposure of antenatal depression were associated with higher risks of high birth weight.

A qualitative study exploring the perinatal experiences of social stress among first- and second-generation immigrant parents in Quebec, Canada

BACKGROUND

Perinatal psychological distress adversely impacts the well-being and social adjustment of parents and their children. Expectant parents who have migrated may be at higher risk for perinatal psychological distress due to various migration-specific stressors and healthcare service barriers. Limited studies have examined the perceived determinants of perinatal distress in immigrant parents, particularly men. This study explored first and second-generation immigrant parents' lived experiences of social stressors and facilitators of perinatal psychological well-being.

METHODS

Participants were recruited by convenience and purposive sampling as part of a larger study. Semi-structured interviews were conducted virtually with first and second-generation immigrant women and men in Quebec, Canada. An inductive thematic analysis was performed.

RESULTS

Sixteen women (age = 34.8 ± 3.7 years) and ten men (age = 35.1 ± 4.9 years) from various ethnic backgrounds participated in the study at 7.4 ± 0.73 and 7.5 ± 0.72 months postpartum, respectively. Three themes were identified: (1) cultural pressures (cultural differences in parenting, gender-related cultural pressures, health and baby-related practices), (2) health and social service access (social benefits and resources, and systemic barriers in health care), and (3) discrimination (physical appearance or parental-related discrimination, gender-related discrimination, ethnic-related discrimination). First-generation immigrant parents reported greater acculturative stress (i.e. mental health stigma, health care access) and ethnic discrimination concerns related to their distress. Among men, barriers include feeling as though the paternal role was devalued by society and not receiving consideration by health care.

CONCLUSIONS

Our results highlight different social factors of perinatal well-being perceived by men and women from various ethnic and immigration backgrounds during the perinatal period. Perceived factors include macro-level factors, such as a country's social climate, health and social policies and services, and social aspects of acculturative stress. Our findings suggest the need for continued efforts to challenge and eliminate discriminatory practices. Interventions and resources directed at first-generation immigrant parents should be bolstered. Understanding what parents perceive to facilitate or hinder their psychological well-being can help inform the development of tailored evidence-based programs and policies to better meet the mental health needs of Canadians and reduce gender disparities in the treatment of perinatal distress.

Antenatal Depression and its Associated Factors: Findings from Kuwait Birth Cohort Study

BACKGROUND

Pregnant and postpartum women are at high risk of depression due to hormonal and biological changes. Antenatal depression is understudied compared to postpartum depression and its predictors remain highly controversial.

AIM

To estimate the prevalence of depressive symptoms during pregnancy and investigate factors associated with this condition including vitamin D, folate and Vitamin B12 among participants in the Kuwait Birth Study.

METHODS

Data collection occurred as part of the Kuwait Birth Cohort Study in which pregnant women were recruited in the second and third trimester during antenatal care visits. Data on antenatal depression were collected using the Edinburgh Postnatal Depression Scale (EPDS), considering a score of ≥ 13 as an indicator of depression. Logistic regression was used to investigate factors associated with depressive symptoms in pregnant women.

RESULTS

Of 1108 participants in the Kuwait Birth Cohort study, 1070(96.6%) completed the EPDS. The prevalence of depressive symptoms was 21.03%(95%CI:18.62-23.59%) and 17.85%(95%CI:15.60-20.28%) as indicated by an EPDS ≥ 13 and EPDS ≥ 14 respectively. In the multivariable analysis, passive smoking at home, experiencing stressful life events during pregnancy, and a lower level of vitamin B12 were identified as predisposing factors. Conversely, having desire for the pregnancy and consumption of fruits and vegetables were inversely associated with depressive symptoms.

CONCLUSION

Approximately, one fifth of pregnant women had depressive symptoms indicating the need to implement screening program for depression in pregnant women, a measure not systematically implemented in Kuwait. Specifically, screening efforts should focus on pregnant women with unintended pregnancies, exposure to passive smoking at home, and recent stressful live events.

Biological and behavioral pathways from prenatal depression to offspring cardiometabolic risk: Testing the developmental origins of health and disease hypothesis

Given prior literature focused on the Developmental Origins of Health and Disease framework, there is strong rationale to hypothesize that reducing depression in the prenatal period will cause improvements in offspring cardiometabolic health. The current review outlines evidence that prenatal depression is associated with offspring cardiometabolic risk and health behaviors. We review evidence of these associations in humans and in nonhuman animals at multiple developmental periods, from the prenatal period (maternal preeclampsia, gestational diabetes), neonatal period (preterm birth, small size at birth), infancy (rapid weight gain), childhood and adolescence (high blood pressure, impaired glucose-insulin homeostasis, unfavorable lipid profiles, abdominal obesity), and into adulthood (diabetes, cardiovascular disease). In addition to these cardiometabolic outcomes, we focus on health behaviors associated with cardiometabolic risk, such as child eating behaviors, diet, physical activity, and sleep health. Our review focuses on child behaviors (e.g., emotional eating, preference for highly palatable foods, short sleep duration) and parenting behaviors (e.g., pressuring child to eat, modeling of health behaviors). These changes in health behaviors may be detected before changes to cardiometabolic outcomes, which may allow for early identification of and prevention for children at risk for poor adult cardiometabolic outcomes. We also discuss the methods of the ongoing Care Project, which is a randomized clinical trial to test whether reducing prenatal maternal depression improves offspring's cardiometabolic health and health behaviors in preschool. The goal of this review and the Care Project are to inform future research, interventions, and policies that support prenatal mental health and offspring cardiometabolic health.

Barriers to assessing vulnerability in pregnant women. A cross-sectional survey in Danish general practice

BACKGROUND

Undetected vulnerability in pregnancy contributes to inequality in maternal and perinatal health and is associated with negative birth outcomes and adverse child outcomes. Nationwide reports indicate important barriers to assessing vulnerability among Danish general practitioners.

OBJECTIVE

To explore general practitioners perceived barriers to vulnerability assessment in pregnant women and whether the barriers are associated with practice organization of antenatal care, general practitioner, and practice characteristics.

METHODS

The questionnaire was sent to all Danish general practitioners (N = 3,465). Descriptive statistics described the barriers to assessing vulnerability in pregnant women. Analytical statistics with ordered logistic regression models were used to describe the association between selected barriers to vulnerability assessment and antenatal care organization, and general practitioner and practice characteristics.

RESULTS

760 general practitioners (22%) answered. Barriers to vulnerability assessment were related to lacking routines for addressing vulnerability, lacking attention to and record-keeping on vulnerability indicators, an insufficient overview of vulnerable pregnant women, and perceived insufficient remuneration for antenatal care consultations. Not prioritizing extra time when caring for vulnerable pregnant women was associated with experiencing more barriers. Always prioritizing continuity of care was associated with experiencing fewer barriers. General practitioners of either young age, male gender, or who did not prioritize extra time to care for vulnerable pregnant women experienced more barriers.

CONCLUSION

Barriers to vulnerability assessment among pregnant women do exist in general practice and are associated with organizational characteristics such as lacking prioritization of extra time and continuity in antenatal care consultations. Also, general practitioner characteristics like male gender and relatively young age are associated with barriers to vulnerability assessment.

Trends and Racial/Ethnic Disparities in Prenatal Care (PNC) Use from 2016 to 2021 in the United States

OBJECTIVES

To investigate the trends and racial/ethnic disparities in adequate prenatal care (PNC) use in the USA.

METHODS

A repeated cross-sectional study was conducted using May 2016-May 2021 data from the Pregnancy Risk Assessment Monitoring System (PRAMS). A primary outcome was the Kotelchuck index, a measure of the adequacy of PNC use, and the year was a key independent variable. Multinomial and binary logistic regression analyses were performed to examine PNC utilization using multiple imputations with chained equations.

RESULTS

Among the 190,262 pregnant individuals, adequate PNC use was largely consistent from 2016 to 2019. However, there was an immediate drop from 77.4-78.3% between 2016 and 2019 to 75.2% in 2020 and 75.8% in 2021. Conversely, both intermediate and inadequate PNC use tended to increase in 2020 and 2021. Adequate PNC use, when compared to inadequate use, showed significantly lower odds in 2020 (adjusted Odds Ratio [aOR] 0.87, 95% CI 0.78-0.96; p = 0.009) and 2021 (aOR 0.87, 95% CI 0.77-0.99; p = 0.033) than in 2016. Notably, Hispanic participants experienced substantial impacts (aOR 0.75, 95% CI 0.64-0.88; p = 0.001 in 2020 and aOR 0.72, 95% CI 0.59-0.89; p = 0.002 in 2021).

CONCLUSIONS

While adequate PNC use was a steady, slightly upward trend before 2020, it had a steep decline afterward. It is worth noting that Hispanic individuals were severely affected. Targeted interventions or policies to address barriers to PNC and foster equitable and sustainable care models are required.

Self-reported problems and functional difficulties in anxious pregnant women in Pakistan: The use of a patient-generated mental health outcome measure

Anxiety during pregnancy affects women worldwide and is highly prevalent in Pakistan. The Psychological Outcome Profiles (PSYCHLOPS) questionnaire is an instrument used in therapy to assess patient-generated problems and the consequent functional difficulties. Using the PSYCHLOPS, we aimed to describe the type of problems and the consequent functional difficulties faced by anxious pregnant women in Pakistan. Secondarily, we sought to explore if a cognitive behavioral therapy (CBT)-based intervention brought about changes in the severity score for certain problems or functional difficulties. Anxious pregnant women were recruited from the Obstetrics/Gynecology Department of a tertiary hospital in Rawalpindi, Pakistan. Of 600 pregnant women randomized to receive a psychosocial intervention for prenatal anxiety delivered by non-specialist providers, 450 received ≥1 intervention session and were administered the PSYCHLOPS. Eight types of problems were identified; worries about the unborn baby's health and development (23%), concerns about family members (13%), and financial constraints (12%) were the most frequently reported primary problems. Severity scores between baseline and the last available therapy session indicated the largest decrease for relationship problems (mean = 2.4) and for concerns about family members (mean = 2.2). For functional difficulties, 45% of the participants reported difficulties in performing household chores, but the intervention showed the greatest decrease in severity scores for mental or emotional functional difficulties. Focus on certain types of patient-generated problems, e.g., relationship problems, could anchor therapy delivery in order to have the greatest impact. Tailored CBT-based intervention sessions have the potential to address important but neglected problems and functional difficulties in anxious pregnant women.

Effect of different physical activity interventions on perinatal depression: a systematic review and network meta-analysis

BACKGROUND

Perinatal depression can have profound impacts on both families and society. Exercise therapy is gradually becoming a widely used adjunct treatment for perinatal depression. Some studies have already focused on the relationship between physical activity and perinatal depression (PND). However, there is currently a lack of systematic and comprehensive evidence to address the crucial question of making optimal choices among different forms of physical activity. This study aims to compare and rank different physical activity intervention strategies and identify the most effective one for perinatal depression.

METHODS

Four databases, namely PubMed, Cochrane Library, Embase, and Web of Science, were searched for randomized controlled trials assessing the impact of physical activity interventions on perinatal depression. The search covered the period from the inception of the databases until May 2024. Two researchers independently conducted literature screening, data extraction, and quality assessment. Network meta-analysis was performed using Stata 15.1.

RESULTS

A total of 48 studies were included in the analysis. The results indicate that relaxation therapy has the most effective outcome in reducing perinatal depression (SUCRA = 99.4%). Following that is mind-body exercise (SUCRA = 80.6%). Traditional aerobics and aquatic sports were also effective interventions (SUCRA = 70.9% and 67.1%, respectively).

CONCLUSION

Our study suggests that integrated mental and physical (MAP) training such as relaxation therapy and mind-body exercise show better performance in reducing perinatal depression. Additionally, while exercise has proven to be effective, the challenge lies in finding ways to encourage people to maintain a consistent exercise routine.

TRIAL REGISTRATION

This study has been registered on PROSPERO (CRD 42,023,469,537).

Prevalence and factors associated with antenatal depressive symptoms across trimesters: a study of 110,584 pregnant women covered by a mobile app-based screening programme in Shenzhen, China

BACKGROUND

Antenatal depression is a significant public health issue affecting pregnant women both globally and in China. Using data from a mobile app-based screening programme, this study explored the prevalence and factors associated with antenatal depressive symptoms across different trimesters in Shenzhen.

METHODS

A retrospective cross-sectional study was conducted on pregnant women who gave birth in any hospital in Shenzhen between July 2021 and May 2022 and underwent depression screening using an official maternal and infant health mobile app at least once during pregnancy. Depressive symptoms were evaluated using the 9-item Patient Health Questionnaire (PHQ-9), with cut-off scores of 5 and 10 for mild and high level of symptoms, respectively. The prevalence for each trimester was determined by calculating the proportion of women scoring 5 or higher. A variety of sociodemographic, obstetric, psychological, and lifestyle factors were assessed for their association with depressive symptoms. Chi-square test and multivariate logistic regression were performed to identify significant predictors.

RESULTS

A total of 110,584 pregnant women were included in the study, with an overall prevalence of depressive symptoms of 18.0% and a prevalence of high-level symptoms of 4.2%. Depressive symptoms were most prevalent in the first trimester (10.9%) and decreased in the second (6.2%) and third trimesters (6.3%). Only a small proportion (0.4%) of women showed persistent depressive symptoms across all trimesters. Anxiety symptoms in early pregnancy emerged as the most significant predictor of depressive symptoms. Other factors linked to an increased risk throughout pregnancy include lower marital satisfaction, living with parents-in-law, experience of negative life events, as well as drinking before and during pregnancy. Factors associated with a reduced risk throughout pregnancy include multiparity and daily physical activity.

CONCLUSIONS

This large-scale study provides valuable insights into the prevalence and factors associated with antenatal depressive symptoms in Shenzhen. The findings underscore the need for targeted interventions for high-risk groups and the integration of mental health care into routine antenatal services. Continuous, dynamic monitoring of depressive symptoms for pregnant women and ensuring at-risk women receive comprehensive follow-up and appropriate psychological or psychiatric care are crucial for effectively addressing antenatal depression and improving maternal and infant health outcomes.

A sum of its parts: A systematic review evaluating biopsychosocial and behavioral determinants of perinatal depression

INTRODUCTION

Depression is one of the most common yet underdiagnosed perinatal complications and our understanding of its pathophysiology remains limited. Though perinatal depression is considered to have a multifactorial etiology, integrative approaches to investigation are minimal. This review takes an integrative approach to systematically evaluate determinants (e.g., biological, behavioral, environmental, social) and interactions among determinants of perinatal depression and the quality of methods applied.

METHODS

Four databases (i.e., PubMed, CINAHL, APA PsycInfo, Web of Science) were systematically searched to identify studies examining determinants of perinatal depression in adult perinatal persons (≥ 18 years). Articles were excluded if the outcomes were not focused on perinatal persons and depression or depression symptoms, depression was examined in a specific subpopulation evidenced to have psychological consequences due to situational stressors (e.g., fetal/infant loss, neonatal intensive care unit admission), or was considered grey literature. The Critical Appraisal Skills Programme and AXIS tools were used to guide and standardize quality appraisal assessments and determine the level of risk of bias.

RESULTS

Of the 454 articles identified, 25 articles were included for final review. A total of 14 categories of determinants were investigated: biological (5), behavioral (4), social and environmental (5). Though only 32% of studies simultaneously considered determinants under more than one domain, a pattern of interactions with the tryptophan pathway emerged. Concerns for risk of bias were noted or were unclear for three types of bias: 13 (52%) selection bias, 3 (12%) recall bias, and 24 (96%) measurement bias.

CONCLUSIONS

Future research is needed to explore interactions among determinants and the tryptophan pathway; to strengthen the methods applied to this area of inquiry; and to generate evidence for best practices in reporting, selecting, and applying methods for measuring determinants and perinatal depression.

Women's engagement with community perinatal mental health services: a realist evaluation

BACKGROUND

In recognition of the burden of Perinatal Mental Health problems, NHS England invested £365 million to transform women's access to mental health care, including investment in Community Perinatal Mental Health Services. This study examined how elements of provider care affected women's engagement with these services.

METHODS

Semi-structured interviews were conducted with 139 women and explored their experiences of care from 10 different Community Perinatal Mental Health Teams; including which service components participants believed made a difference to their initial and continued engagement. Realist analysis was used to create context-mechanism-outcome configurations (CMOCs) across interviews, since not all parts of the configurations were always articulated within singular interviews.

RESULTS

Four key pillars for engagement were identified: perinatal competence, relationship building, accurate reassurance, and reliability. The way perinatal competencies were relayed to women mattered; compassion, understanding and consistency were critical interactional styles. The extent to which these factors affected women's engagement varied by their context and personal characteristics.

CONCLUSIONS

As mental health problems increase, disproportionately affecting vulnerable populations, it is critical to continue to ensure support is not only available, but appropriately meets the needs of those individuals. Our findings suggest that key staff behaviours applied at the right time can support women's engagement and potentially contribute to better treatment outcomes.

A Network Analysis of Perinatal Depression, Anxiety, and Temperaments in Women in the First, Second, and Third Trimesters of Pregnancy

Background/Objectives: Although depression and anxiety are found to be affected by temperaments, little research has studied these relationships in pregnancy. The present study explored the associations among perinatal depression (PD), anxiety dimensions (state, trait, and generalized anxiety disorder (GAD)), and temperaments between women in the three trimesters of pregnancy through a network analysis approach. Moreover, differences in the severity of PD and anxiety between women in the three trimesters were evaluated. Methods: Women in first (N = 31), second (N = 184), and third (N = 54) trimesters of pregnancy were recruited in the present cross-sectional study. The network analysis included PD, anxiety dimensions, and temperaments. Three network models were estimated, and ANOVAs evaluated the differences in the severity of PD and anxiety, including trimesters as a between-subject factor. Results: PD and GAD were the nodes most strongly connected across the three groups. Cyclothymic, depressive, and anxious temperaments were most frequently associated with PD and GAD. Hyperthymic temperament was in the periphery of the three networks. Lastly, women in the first trimester had the highest severity of PD and GAD. Conclusions: PD and GAD showed the strongest associations. Anxiety dimensions had positive associations with PD and GAD, suggesting their role as possible risk factors. Temperaments were differently associated within the network between the three groups. Clinical interventions during pregnancy should target the central variables, considering their direct and indirect relationships.

Factors effecting on health-promoting behaviors in iranian pregnant women and their husbands: the actor-partner interdependence model (APIM)

INTRODUCTION

Pregnancy is an important period of life for women and their husbands as the couple's health is essential. The present study evaluated the impact of some factors (marital adjustment with depressive symptoms) on health-promoting behaviors in pregnant women and their husbands based on the actor-partner interdependence model (APIM).

MATERIALS AND METHODS

This descriptive study examined 211 couples (pregnant women and their husbands) in pregnancy clinics of Babol University of Medical Sciences using a convenience sampling method. The participants completed Spanier's Dyadic Adjustment Scale (DAS) (1979), Edinburgh Postnatal Depression Scale (EPDS) (1987), and Walker's Health Promoting Lifestyle Profile II (HPLPII) questionnaire (1997). The relationships between women and their husbands were also evaluated using structural equation modeling with R software according to the Lavaan (latent variable analysis) package based on APIM-SEM.

RESULTS

The pregnant women's marital adjustment positively affected their health-promoting behaviors (β = 0.456, 95% Cl: 0.491-0.998, p < 0.001) and their husbands' (β = 0.210, 95% Cl: 0.030-0.726, p = 0.048). Pregnant woman's depressive symptoms also negatively affected their health-promoting behaviors (β=-0.088, 95% Cl: -0.974-0.074, P = 0.236) and their husbands' health-promoting behaviors (β=-0.177, 95% Cl: -0.281 - -0.975, P = 0.011). Furthermore, the husband's marital adjustment only positively affected his studied behaviors (β = 0.323, 95% Cl: 0.0303-0.895, P < 0.001) but did not affect the pregnant woman's health behaviors. The husband's depressive symptoms had a negative impact on his studied behaviors (β = 0.219, 95% Cl: -0.122 - -0.917, P = 0.001) and did not affect the pregnant woman's depressive symptoms. Our findings confirmed the mediating role of depressive symptoms in pregnant women and their husbands on the association of marital adjustment and health-promoting behaviors. According to the actor-partner study, a pregnant woman's marital adjustment scores positively affected her studied behaviors and her husband (β = 0.071, 95% Cl: 0.042-0.278, P = 0.015) by decreasing her depression score. Therefore, the husband's marital adjustment score positively affected his studied behaviors by decreasing his depression score (β = 0.084, 95% Cl: -0.053 -0.292, P = 0.005), and it did not affect his wife's health-promoting behaviors.

DISCUSSION AND CONCLUSION

These findings suggest healthcare providers, obstetricians, and psychologists evaluate the husbands' symptoms of depression and health-promoting behaviors in the routine pregnancy care of pregnant women. They also pay great attention to marital adjustment as a determinant of reducing depressive symptoms in pregnant women and their husbands.

Association between antenatal common mental disorders symptoms, and adverse obstetric and perinatal outcomes: A community-based prospective cohort study in Eastern Ethiopia

BACKGROUND

Maternal common mental disorders have broad implications for maternal and child mental and physical health that may have a long-lasting social and economic impact. This study aimed to assess the association between symptoms of antenatal common mental disorders and obstetric and perinatal outcomes in Eastern Ethiopia.

METHODS

A community-based prospective cohort study was conducted and a total of 1011 randomly selected pregnant women were followed up from February 1, 2021, to January 30, 2022. The modified Poisson regression model with a robust variance was fitted to examine the effect of the symptoms of antenatal common mental disorders on obstetric and perinatal outcomes.

RESULTS

Antenatal common mental disorders (SRQ ≥ 6) were presented among 390 (38.58 %) pregnant women. In the final multivariate Poisson regression model, women with antenatal common mental disorders symptoms had an increased risk of some pregnancy complications (ARR = 1.65, 95 % CI: 1.59, 1.84). In the current study, symptoms of antenatal common mental disorders increased also the risk of preterm birth (ARR = 1.71; 95 % CI: 1.20, 2.42) and low birth weight (ARR = 1.93; 95 % CI: 1.36, 2.74).

LIMITATION

The indirect effects of some potential mediators and moderators were not assessed in this study.

CONCLUSION

The study found a high rate of symptoms of antenatal common mental disorders and adverse obstetric and perinatal outcomes. Antenatal common mental disorders symptoms may have considerable effects on individual and combined pregnancy complications and adverse perinatal outcomes.

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.

Maternal Well-Being in Pregnancy and Breastfeeding Practices: Findings from the ROLO Study

OBJECTIVE

Low mood is common during the perinatal period, which may negatively impact breastfeeding practices. Exploring predictors of successful breastfeeding is a health priority area. This study investigated if maternal well-being during pregnancy is associated with breastfeeding practices.

STUDY DESIGN

This is a secondary analysis of a randomized control trial of a low glycemic index diet in pregnancy. A total of 610 secundigravida women were recruited in the National Maternity Hospital, Dublin, Ireland. Data on maternal education attainment, early pregnancy body mass index (BMI), and age were collected from hospital records. Well-being was self-reported by mothers between 10 and 28 weeks' gestation using the World Health Organization 5-Item well-being index. Scores were transformed to give percentage well-being. Mothers recorded breastfeeding practices at hospital discharge and at the study follow-up appointments. Chi-squares and independent t-tests determined initial differences in breastfeeding practices. Multiple and logistic regression analyses were used to adjust for confounders.

RESULTS

Average maternal age was 32.7 years; average BMI was 26.6 kg/m2, and 56% had achieved third-level education. The average well-being score was 58.2%. In unadjusted analysis, high well-being scores were associated with exclusive breastfeeding (56.2% breastfed vs. 46%, breastfed p < 0.03). After adjusted analysis, these associations were no longer significant (odds ratio: 1.00, 95% confidence interval: 0.99-1.01). No other associations were found.

CONCLUSION

Our findings indicated 25% of pregnant women in the first trimester reported low well-being scores. Associations between maternal well-being and breastfeeding patterns were explained by maternal age and education level, suggesting low mood may not be a barrier to breastfeeding initiation or duration. This trial is registered at: https://www.isrctn.com/ ISRCTN54392969.

KEY POINTS

· Well-being during pregnancy is often diminished and the WHO 5-Item well-being index is a useful measure in clinical settings to assess maternal well-being.. · Breastfeeding is a high-priority research area, particularly in an Irish setting.. · Well-being was not related to breastfeeding, however age, BMI and education were the main predictors of low well-being during pregnancy..

Difficulties in Pregnancy Adjustment as Predictors of Perinatal Depression: Indirect Effects through the Role of Brooding Rumination and Maternal-Fetal Bonding

OBJECTIVE

 The aim of this research was to study the ways in which problems of adaptation to pregnancy influence the development of symptoms of perinatal depression via the presence of brooding and low maternal-fetal bonding, in addition to other risk factors previously established in the literature.

STUDY DESIGN

 Representative sample of pregnant women in the third trimester of gestation (N = 594) completed an online survey that included sociodemographic data and measures of perinatal depression, adjustment to pregnancy, bonding, and brooding. Other risk factors were also assessed as covariates, such as previous history of depression, generalized anxiety, perceived social support, and experience of stressful life events. Descriptive and correlational analyses were performed on the scores obtained by the subjects with the different instruments. A path model was formulated to establish the pathways through which adjustment influences perinatal depression symptomatology. On the one hand, the presence of brooding (worst adjustment to pregnancy → high brooding → perinatal depression symptomatology), and on the other hand, the quality of maternal-fetal bonding (worst adjustment to pregnancy → poor quality fetal-maternal bonding → perinatal depression symptomatology) would act as a mediator.

RESULTS

 The factors proposed by the literature were predictive of perinatal depressive symptomatology and the quality of adjustment to pregnancy. Problems adjusting to changes during pregnancy and experiencing it unsatisfactorily may predict individual differences in perinatal depressive symptoms. Significantly, this relationship was mediated by two key factors, the presence of brooding and low quality of the maternal-fetal bond.

CONCLUSION

 Our results provide evidence in favor of the existence of multiple paths through which difficulties in adapting to pregnancy can favor the occurrence of higher levels of perinatal depressive symptoms and identify new avenues for developing research in this area and preventive interventions empirically informed.

Environmental enrichment attenuates depressive-like behavior in maternal rats by inhibiting neuroinflammation and apoptosis and promoting neuroplasticity

Gestational stress can exacerbate postpartum depression (PPD), for which treatment options remain limited. Environmental enrichment (EE) may be a therapeutic intervention for neuropsychiatric disorders, including depression, but the specific mechanisms by which EE might impact PPD remain unknown. Here we examined the behavioral, molecular, and cellular impact of EE in a stable PPD model in rats developed through maternal separation (MS). Maternal rats subjected to MS developed depression-like behavior and cognitive dysfunction together with evidence of significant neuroinflammation including microglia activation, neuronal apoptosis, and impaired synaptic plasticity. Expanding the duration of EE to throughout pregnancy and lactation, we observed an EE-associated reversal of MS-induced depressive phenotypes, inhibition of neuroinflammation and neuronal apoptosis, and improvement in synaptic plasticity in maternal rats. Thus, EE effectively alleviates neuroinflammation, neuronal apoptosis, damage to synaptic plasticity, and consequent depression-like behavior in mother rats experiencing MS-induced PPD, paving the way for new preventive and therapeutic strategies for PPD.

Self-Reported Causes of Psychological Distress Among Czech Perinatal Women

BACKGROUND

Various risk factors to perinatal mental health disorders have been described; however, there is a dearth of data on the perspectives of women themselves regarding what increases the risk of psychological distress. This qualitative study explores women's perceptions of factors that increase the risk of perinatal psychological distress.

AIM

The aim of this study was to elucidate women's perceptions of factors that increase the risk of perinatal psychological distress.

METHODS

A qualitative design with an exploratory and descriptive approach is used. Women (N = 188) aged 18 to 45 years who self-report experiencing perinatal psychological distress complete an online survey.

RESULTS

Perceived causes of perinatal psychological distress include: adverse experiences with childbirth and/or breastfeeding, negative attitudes of people close to the participant, financial and social challenges, health challenges, staff behavior in a maternity hospital, a challenging baby, family circumstances, and the new role as mother.

CONCLUSION

Women's perceived causes of perinatal psychological distress may allow for women-centered innovations in perinatal mental health care. The results highlight the need to train maternity staff regarding perinatal mental health and communication. These findings can serve as important guidelines on women-centered planning of innovations of perinatal mental health care. Interventions need to focus on the role of partners and others close to women so as to support the women during the perinatal period.

The association between epidural labour analgesia and postpartum depression: a randomised controlled trial

There is conflicting evidence regarding the association between epidural labour analgesia and risk of postpartum depression. Most previous studies were observational trials with limited ability to account for confounders. We aimed to determine if epidural analgesia was associated with a significant change in the incidence of postpartum depression in this randomised controlled trial. We enrolled women aged 21-50 years old with a singleton fetus ≥ 36 weeks gestation. Patients were advised regarding available labour analgesic modalities during enrolment (epidural block; intramuscular pethidine; nitrous oxide; or intravenous remifentanil). On request for analgesia, patients were offered the modality that they had been allocated randomly to first. Blinded investigators recorded patient and obstetric characteristics within 24 h of delivery and assessed for postpartum depression at 6-10 weeks following delivery using the Edinburgh Postnatal Depression Scale (score ≥ 13 considered positive for postpartum depression). The modified intention-to-treat population consisted of all patients who received any form of labour analgesia, while per-protocol consisted of patients who received their randomised modality as their first form of labour analgesia. Of 881 parturients allocated randomly (epidural n = 441, non-epidural n = 440), we analysed 773 (epidural n = 389, non-epidural n = 384); 62 (15.9%) of women allocated to epidural group developed postpartum depression compared with 65 (16.9%) women allocate to the non-epidural group. There were no significant differences in the incidence of postpartum depression between the two groups (adjusted risk difference (95%CI) 1.6 (-3.0-6.3%), p = 0.49). Similar results were obtained with per-protocol analysis (adjusted risk difference (95%CI) -1.0 (-8.3-6.3%), p = 0.79). We found no significant difference in the risk of postpartum depression between patients who received epidural labour analgesia and those who utilised non-epidural analgesic modalities.

Persistent depression in pregnant refugee and migrant women living along the Thai-Myanmar Border: a secondary qualitative analysis

Background

Antepartum depression affects around 15% of pregnant women worldwide, and may negatively impact their infants' physical, cognitive and social development, and confer a greater risk of emotional dysregulation in their children. Risk factors for antepartum depression disproportionately affect women from resource-sparse settings. In particular, pregnant refugee and migrant women face many barriers to diagnosis and care of mental health conditions, yet this group is under-represented in the literature. This study explores what refugee and migrant women living along the Thai-Myanmar border perceive as being contributory and protective factors to their antepartum depression, through secondary qualitative analysis of responses to clinical interviews for depression.

Methods

Previous research investigating perinatal depression in pregnant refugee and migrant women on the Thai-Myanmar border involved assessing 568 women for depression, using the Structured Clinical Interview for the diagnosis of DSM-IV Disorders (SCID). This study analyses a subsample of 32 women, diagnosed with persistent depression during the antepartum period. Thematic analysis of responses to the SCID and social and demographic surveys was undertaken to investigate factors which contribute towards, or protect against, persistent antepartum depression.

Results

Major themes which women described as contributing towards persistent antepartum depression were financial problems, interpersonal violence, substance misuse among partners, social problems and poor health. Factors women considered as protecting mental wellbeing included social support, accessible healthcare and distractions, highlighting the need for focus on these elements within refugee and migrant settings. Commonly expressed phrases in local Karen and Burmese languages were summarised.

Conclusions

Knowledge of factors affecting mental wellbeing in the study population and how these are phrased, may equip stakeholders to better support women in the study area. This study highlighted the limitations of contextually generic diagnostic tools, and recommends the development of tools better suited to marginalised and non-English speaking groups.

Influencing factors of sleep quality in pregnant: a structural equation model approach

BACKGROUND

To describe the changes in the level of sleep quality during pregnancy among pregnant women in Urumqi; also to construct a structural equation model of the factors influencing the sleep quality of pregnant women, to analyze the path relationship between the influencing factors, and to take reasonable interventions to prevent and reduce the occurrence of sleep disorders among pregnant women.

METHODS

986 pregnant women who gave birth in Urumqi Maternal and Child Health Hospital and Urumqi Youai Hospital between August 2021 and May 2023 were selected. The Pittsburgh Sleep Quality Index (PSQI), Self-Rating Anxiety Scale (SAS), and Edinburgh Postpartum Depression Scale (EPDS) were used to assess the sleep, anxiety, and depression of pregnant women, Building a structural equation model based on AMOS 23.0 Tools.

RESULTS

The results of structural equation modeling showed that: basic characteristics, obstetrical characteristics, tocolysis, lifestyle, psychological had a direct effect on the PSQI, with path coefficients of 0.243, 0.106, 0.140, 0.174, 0.658, the corresponding T-values for each path are 4.585, 2.677, 2.578, 2.297, and 9.036. The indirect effect of basic characteristics, obstetric characteristics and lifestyle on PSQI was 0.123, 0.020, 0.027.

CONCLUSIONS

The high incidence of sleep disorders in pregnant women and their close association with psychological symptoms in pregnant women should focus on screening and counseling regarding psychological disorders in pregnant women, thus improving the quality of sleep in pregnant women.

Magnitude and determinants of psychological morbidities among pregnant women: Results from a pregnancy cohort in rural Central India

Background

Psychological morbidities are one of the emerging global health problems. It affects a considerable number of ante-natal women leading to consequences during the postnatal period as well. We conducted this research to study the magnitude and determinants of psychological morbidities during pregnancy.

Methods

In this study, we included 650 pregnant women from an established cohort of 2500 pregnant women and assessed the psychological morbidities among them using the GMHAT/PC tool.

Results

The overall prevalence of psychological morbidities during pregnancy was 14.6%, with anxiety and depression being the leading ones. Low education levels, lower socio-economic status, unintended pregnancy, complicated previous pregnancy, lack of family and social support, and domestic violence increased the odds of psychological morbidity. On Multivariate logistic regression, Low education levels increased the odds to more than twice [illiterate/primary schooling OR: 4.00, p = 0.026; secondary schooling OR: 2.64, p = 0.034; high school OR: 2.60, p = 0.033] unintended pregnancy [OR: 1.91, p = 0.043] and lack of family support [OR: 7.19, p < 0.001] increased the odds of psychological morbidity among pregnant women.

Conclusion

Bringing these issues to the mainstream and addressing them by developing interventions to address them during the lifecycle of a female will help to prevent episodes of psychological stress and morbidity among pregnant females.

Stress and depression-associated shifts in gut microbiota: A pilot study of human pregnancy

Background

Psychosocial stress and mood-related disorders, such as depression, are prevalent and vulnerability to these conditions is heightened during pregnancy. Psychosocial stress induces consequences via several mechanisms including the gut microbiota-brain axis and associated signaling pathways. Previous preclinical work indicates that prenatal stress alters maternal gut microbial composition and impairs offspring development. Importantly, although the fecal and vaginal microenvironments undergo alterations across pregnancy, we lack consensus regarding which shifts are adaptive or maladaptive in the presence of prenatal stress and depression. Clinical studies interrogating these relationships have identified unique taxa but have been limited in study design.

Methods

We conducted a prospective cohort study of pregnant individuals consisting of repeated administration of psychometrics (Perceived Stress Scale (PSS) and Center for Epidemiological Studies Depression Scale (CES-D)) and collection of fecal and vaginal microbiome samples. Fecal and vaginal microbial community composition across psychometric responses were interrogated using full-length 16S rRNA sequencing followed by α and β-diversity metrics and taxonomic abundance.

Results

Early pregnancy stress was associated with increased abundance of fecal taxa not previously identified in related studies, and stress from late pregnancy through postpartum was associated with increased abundance of typical vaginal taxa and opportunistic pathogens in the fecal microenvironment. Additionally, in late pregnancy, maternal stress and depression scores were associated with each other and with elevated maternal C-C motif chemokine ligand 2 (CCL2) concentrations. At delivery, concordant with previous literature, umbilical CCL2 concentration was negatively correlated with relative abundance of maternal fecal Lactobacilli. Lastly, participants with more severe depressive symptoms experienced steeper decreases in prenatal vaginal α-diversity.

Conclusion

These findings a) underscore previous preclinical and clinical research demonstrating the effects of prenatal stress on maternal microbiome composition, b) suggest distinct biological pathways for the consequences of stress versus depression and c) extend the literature by identifying several taxa which may serve critical roles in mediating this relationship. Thus, further interrogation of the role of specific maternal microbial taxa in relation to psychosocial stress and its sequelae is warranted.

Path analysis of influencing factors for maternal antenatal depression in the third trimester

Maternal antenatal depression (AD) is a nonpsychotic depressive episode during pregnancy that can harm both the pregnant woman and the fetus. This study aimed to investigate the intrinsic interrelationships between AD and its influencing factors by constructing a path model. This survey-based cross-sectional study included 1071 pregnant women who underwent pregnancy examinations in three hospitals in Nantong City, China, between February and June 2023. General information and information regarding maternal AD, pregnancy stress, prenatal anxiety, social support, marital satisfaction, sleep quality, and resilience were collected. Multiple linear regression analysis using SPSS 25.0 was employed to determine the factors influencing pregnancy depression, and Amos25.0 was used to construct a structural equation model. AD incidence was 19.4% (208/1071). The independent risk factors affecting AD in pregnant women have been integrated into the established path analysis model. The model demonstrated a good fit (χ2/DF = 1.238, comparative fit index = 0.999, goodness-of-fit index = 0.998, normed fit index = 0.996, adjusted goodness-of-fit index = 0.990, incremental fit index = 0.999, and root mean square error of approximation = 0.015). While prenatal anxiety (0.230) and hyperthyroidism (0.048) only had direct effects on AD, mental resilience was the biggest factor affecting AD, followed by pregnancy stress, marital satisfaction, prenatal anxiety, sleep quality, social support, and hyperthyroidism. Improved mental resilience, social support, sleep quality, and marital satisfaction; reduced pregnancy stress and prenatal anxiety; and effective hyperthyroidism treatment might reduce AD. This study underscored the significance of delivering actionable strategies and tangible assistance to pregnant women to reduce AD.

Associations of maternal prenatal psychological symptoms and saliva cortisol with neonatal meconium microbiota: A cross-sectional study

Alterations in the diversity and relative abundances of the gut microbiome have been associated with a broad spectrum of medical conditions. Maternal psychological symptoms during pregnancy may impact on offspring development by altering the maternal and the foetal gut microbiome. We aimed to investigate whether self-reported maternal anxiety, depressive symptoms, and distress as well as saliva cortisol levels in late pregnancy alter the bacterial composition of the infant's meconium.

METHODS

A total of N = 100 mother-infant pairs were included. Maternal psychological symptoms were measured using psychological questionnaires (EPDS, PSS-10, STAI) at 34-36 weeks gestation and salivary cortisol was measured at 34-36 and 38 weeks gestation. Infant meconium samples were collected in the first five days postpartum and analysed using 16S rRNA amplicon sequencing.

RESULTS

Correlations showed that lower alpha diversity of the meconium microbiome was significantly associated with increased maternal prenatal depressive symptoms in late gestation (τ = -0.15, p = .04). Increased saliva cortisol AUCg at T2 was significantly related to higher beta diversity of the meconium samples (Pr(>F) = 0.003*). Pseudomonas was the most abundant phylum and was associated with maternal saliva cortisol total decline. No other associations were found.

CONCLUSIONS

Maternal prenatal depressive symptoms are associated with infant faecal microbiome alpha diversity, whereas maternal saliva cortisol AUCg is linked to increased beta diversity and total decline related to increased Psuedomonas. Future studies are warranted to understand how these microbiota community alterations are linked to child health outcomes.

[Evaluation of Psychological Distress in Obstetric Patients during the Visit Ban in Hospitals in the SARS-CoV-2 Pandemic: A Prospective, Multicentre, Controlled Study]

INTRODUCTION

Risk factors for postpartum depression include a lack of social support and perceived social isolation. We would like to determine whether the isolation of inpatients on the maternity wards during Covid-19 leads to increased psychological stress.

METHODS

This is a multicentre, controlled study of obstetric patients who gave birth during an inpatient stay. Patients were included during the visitation ban (study group) and after the visitation ban (control group). Psychological stress was evaluated with the Edinburgh Postnatal Depression Scale (EPDS) during the inpatient stay and six to eight weeks postpartum.

RESULTS

A total of 194 women were included, 107 in the study group and 87 in the control group. The overall result of the first EPDS shows a higher score in the study group compared to the control group (7.0 vs. 4.9 points). Primipara show a higher score in the first EPDS compared to multipara (7.28 vs. 4.82). Caesarean section, regardless of isolation, shows a higher score in the first EPDS than vaginal birth (8.42 vs. 5.11). Comparison of vaginal birth shows a higher score only in the study group (5.97 vs. 4.07).

CONCLUSION

In the context of Covid-19, women giving birth and new mothers, especially primipara, are exposed to increased psychological stress in the clinics. Caesarean section leads to increased psychological stress.

Impact of the COVID-19 pandemic on new parents enrolled in the 'BABY1000' birth cohort study in Sydney, Australia: A mixed-methods study

OBJECTIVE

The COVID-19 pandemic was, and continues to be, uniquely experienced by women in the perinatal period and their families. Whilst long-term impacts of the pandemic are unknown, exposures in pregnancy and early life have impacts across the life-course and future generations. The objective of this manuscript was to explore how the pregnancy, postpartum and parenting experiences of a subset of participants from the 'BABY1000' cohort in Sydney, Australia, were affected by the COVID-19 pandemic, and explore associations between these experiences and state anxiety.

METHODS

Mixed methods were used. Participants were requested to complete an online survey including the State-Trait Anxiety Inventory short form (STAI-6), followed by an invitation to participate in focus group discussions (FGDs).

RESULTS

From September to November 2021, 88 parents completed the survey (mean age 33.5 years, 60% born in Australia, 58% primiparous). Twenty-two parents participated in FGDs. Six themes were identified regarding the experience of parents: (1) Maternal support, (2) Family relationships, (3) Stress and mental health, (4) Healthcare, (5) Family lifestyle and routine, and (6) Long-term impacts. The mean STAI-6 score was 40 (SD 12.3), representing high anxiety. High anxiety was significantly associated with concern regarding COVID-19 and feeling overburdened and lonely.

CONCLUSIONS

The COVID-19 pandemic and associated public health orders significantly impacted participants' pregnancy, postpartum and parenting experiences. Whilst these experiences included some unexpected positives, for many, these were outweighed by negative impacts on mental health, social support, health behaviours, and family relationships.

IMPLICATIONS FOR PUBLIC HEALTH

Ongoing longitudinal research is imperative to identify potential long-term effects of the pandemic across the life-course, better support families in the short and long-term, and plan for public health crises in the future.

Perinatal depression and risk of mortality: nationwide, register based study in Sweden

OBJECTIVE

To determine whether women with perinatal depression are at an increased risk of death compared with women who did not develop the disorder, and compared with full sisters.

DESIGN

Nationwide, register based study.

SETTING

Swedish national registers, 1 January 2001 to 31 December 2018.

PARTICIPANTS

86 551 women with a first ever diagnosis of perinatal depression ascertained through specialised care and use of antidepressants, and 865 510 women who did not have perinatal depression were identified and matched based on age and calendar year at delivery. To address familial confounding factors, comparisons were made between 270 586 full sisters (women with perinatal depression (n=24 473) and full sisters who did not have this disorder (n=246 113)), who gave at least one singleton birth during the study period.

MAIN OUTCOME MEASURES

Primary outcome was death due to any cause. Secondary outcome was cause specific deaths (ie, unnatural and natural causes). Multivariable Cox regression was used to estimate hazard ratios of mortality comparing women with perinatal depression to unaffected women and sisters, taking into account several confounders. The temporal patterns of perinatal depression and differences between antepartum and postpartum onset of perinatal depression were also studied.

RESULTS

522 deaths (0.82 per 1000 person years) were reported among women with perinatal depression diagnosed at a median age of 31.0 years (interquartile range 27.0 to 35.0) over up to 18 years of follow-up. Compared with women who did not have perinatal depression, women with perinatal depression were associated with an increased risk of death (adjusted hazard ratio 2.11 (95% confidence interval 1.86 to 2.40)); similar associations were reported among women who had and did not have pre-existing psychiatric disorder. Risk of death seemed to be increased for postpartum than for antepartum depression (hazard ratio 2.71 (95% confidence interval 2.26 to 3.26) v 1.62 (1.34 to 1.94)). A similar association was noted for perinatal depression in the sibling comparison (2.12 (1.16 to 3.88)). The association was most pronounced within the first year after perinatal depression but remained up to 18 years after start of follow up. An increased risk was associated with both unnatural and natural causes of death among women with perinatal depression (4.28 (3.44 to 5.32) v (1.38 (1.16 to 1.64)), with the strongest association noted for suicide (6.34 (4.62 to 8.71)), although suicide was rare (0.23 per 1000 person years).

CONCLUSIONS

Even when accounting for familial factors, women with clinically diagnosed perinatal depression were associated with an increased risk of death, particularly during the first year after diagnosis and because of suicide. Women who are affected, their families, and health professionals should be aware of these severe health hazards after perinatal depression.
