Postpartum Perceived Stress Explains the Association between Perceived Social Support and Depressive Symptoms

Socio-demographic, family, and health-related predictors of maternal mental health trajectories during eight years postpartum in a national cohort of 17,886 mothers in Taiwan

BACKGROUND

Previous studies on maternal postpartum mental health are limited by non-representative samples, a narrow focus on mental illness, and a lack of systematic examination of predictors for diverse mental health trajectories. We investigated maternal mental health trajectories during eight years postpartum and their socio-demographic, family, and health-related predictors in a large cohort of mothers in Taiwan.

METHODS

Participants were 17,886 mothers drawn from the Taiwan Birth Cohort Study (TBCS), a cohort study of a nationally representative sample of children born in Taiwan in 2005 and their parents. Maternal mental health was assessed at 6, 18, 36, 66, and 96 months postpartum using the Mental Component Summary (MCS) from the 36-item Short-Form Health Survey (SF-36) Taiwan version. We used group-based trajectory modeling to identify trajectory groups of maternal mental health and examined their predictors using multinomial logistic regression.

RESULTS

Five postpartum mental health trajectories were identified: persistently poor (6.7%), improving (12.1%), deteriorating (14.3%), persistently moderate (46.7%), and persistently good (20.1%), with the first two groups having the poorest mental health at six months postpartum. Immigrant status and higher household income were associated with favorable (i.e., improving, or persistently moderate or good) mental health trajectories, while low family function and poor general health at six months postpartum were associated with less favorable (i.e., deteriorating or persistently poor) trajectories. Among mothers with poor mental health at six months postpartum, being divorced or separated was additionally associated with persistently poor mental health. Among mothers with moderate mental health at six months postpartum, being a first-time mother was additionally associated with deteriorating mental health.

CONCLUSION

Our findings highlight distinct maternal mental health trajectories over eight years postpartum, with one in five mothers experiencing deteriorating or persistently poor mental health. Socio-demographic factors, family function, and early postpartum health were predictors of these trajectories.

Perceived Stress and Early Postpartum Depressive Symptoms in Women with Recent GDM: Implications for Postpartum Lifestyle Programs

OBJECTIVES

To inform the development and adaptation of lifestyle programs to prevent type 2 diabetes, we sought to identify factors associated with depressive symptoms in the early postpartum period among women with recent gestational diabetes (GDM).

METHODS

Participants are from the Balance after Baby Intervention (BABI) study, a two-year randomized clinical trial of a lifestyle program for women with recent GDM conducted in Boston, MA, and Denver, CO between 2016 and 2019. The Edinburgh Postpartum Depression Scale (EPDS) and Perceived Stress Scale (PSS-10) were administered at an average of 8-weeks postpartum. We defined an EPDS score of ≥ 9 as depressive symptoms and reviewed medical records for medical history. We conducted bivariate analyses to identify predictors of postpartum depressive symptoms, then modeled the odds of postpartum depressive symptoms using multivariable logistic regression and selected the best fit model.

RESULTS

Our analysis included 181 women. Thirty-five (19%) scored ≥ 9 on the EPDS. While both perceived stress and whether this was the first pregnancy complicated by GDM were significant in the bivariate analysis, only perceived stress remained a significant predictor of postpartum depressive symptoms in the multivariate regression model (OR 4.34, 95% CI [2.58-7.31]). The effect of first GDM pregnancy was no longer significant in the multivariate model (OR 2.00, 95% CI [0.63-6.33]). Additionally, a mediation model determined that perceived stress fully mediated the effect of first GDM pregnancy on depressive symptoms (Effect ratio, 0.5507/1.5377 = 0.358, p = 0.036).

CONCLUSIONS FOR PRACTICE

Perceived stress was predictive of postpartum depressive symptoms in women with recent GDM and was found to mediate the relationship between first pregnancy complicated by GDM and postpartum depressive symptoms. Addressing perceived stress in the early postpartum period may be an important target for future lifestyle programs to maximize diabetes prevention efforts.

Postpartum Stress and the Occurrence of Breastfeeding-Related Spine Musculoskeletal Disorders Among Lactating Mothers in the Dschang Health District, Cameroon

Background and objective While postpartum stress (PPS) is a problem generally neglected in the literature, its consequences are devastating for both mothers and their babies. This study aimed to evaluate the role of PPS in the occurrence of spine musculoskeletal disorders among lactating mothers in the Dschang Health District, Cameroon. Methods We conducted a cross-sectional study from August 1 to September 29, 2024, involving 422 lactating mothers. Data on PPS were obtained using the Maternal Postpartum Stress Scale (MPSS), and those on the occurrence of breastfeeding-related spine musculoskeletal disorders (BSMSDs) were gathered using the Nordic Musculoskeletal Questionnaire (NMQ). Odds ratios (OR) were calculated, and logistic regression was performed to determine associations. The significance level was set at p<0.05, and the confidence interval (CI) was set at 95%. Stressed women were defined as those with at least a moderate score on the MPSS scale (MPSS score ≥29). Results The prevalence rate of BSMSDs in our cohort was 192 (45.5%) with the low back being the most affected area (n=122, 63.5%). The prevalence rate of stress in women was 241 (57.1%). No association was found between PPS and the occurrence of BSMSDs. However, having a secondary scholar-level education [adjusted odds ratio (aOR): 0.57; 95% CI: 0.38-0.87, p˂0.001) and a breastfeeding (BF) session lasting less than 30 minutes (aOR: 0.53; 95% CI: 0.35-0.82; p˂0.001) correlated with a lower incidence of BSMSDs. Conclusions Despite the high prevalence of BSMSDs and PPS in lactating women, there was no association between PPS and the occurrence of BSMSDs. Several studies in developed countries have investigated the involvement of stress in the occurrence of MSDs in postpartum women. However, no study to date has evaluated the impact of PPS on the occurrence of spine MSDs among Cameroonian BF women. Data are scarce concerning PPS and the occurrence of spine MSDs, leading to a gap in knowledge and awareness about implementing measures to prevent both PPS and MSDs.

The association between social support and postpartum post-traumatic stress disorder

BACKGROUND

Postpartum post-traumatic stress disorder (PTSD) is a debilitating condition that can arise following childbirth. Despite a growing body of research on postpartum mental health, the relationship between social support and postpartum PTSD remains unclear. This study aimed to assess the association between social support and postpartum PTSD.

METHODS

A prospective cohort study was conducted at a tertiary hospital in Guangdong province of China between November 2022 and April 2023. Eligible mothers were assessed for social support using the Social Support Rating Scale (SSRS) at three days postpartum and for PTSD using the Perinatal Post-Traumatic Stress Disorder Questionnaire (PPQ) at 42 days postpartum. The association between social support and postpartum PTSD was analyzed using multiple linear and log-binomial regression, with adjustments for potential confounders.

RESULTS

Forty-six of 560 (8.2%) mothers developed PTSD within 42 days postpartum. Scores for subjective support (β=-0.319, P < 0.001), objective support (β=-0.327, P < 0.001), support availability (β=-0.285, P < 0.001), and overall social support score (β=-0.428, P < 0.001) were inversely associated with PTSD scores. Compared to mothers in the 1st quartile of the overall social support score, those in the 2nd, 3rd, and 4th quartiles had adjusted relative risks of 0.39 (95% confidence interval [CI]: 0.21-0.74), 0.20 (95% CI: 0.09-0.45), and 0.10 (95% CI: 0.03-0.33), respectively, of developing PTSD. An inverse linear trend in the risk of PTSD was observed with increasing social support (P-trend < 0.001).

CONCLUSIONS

Social support may have a protective effect against postpartum PTSD, with practical implications for interventions targeting various dimensions of support.

Social Support and Postpartum Depressive Symptoms in Portuguese Women: The Mediating Role of Emotion Regulation Difficulties

Background/Objectives: Postpartum depression (PPD) is a prevalent mental health issue affecting 14% of mothers worldwide, with long-term implications for both maternal and child well-being. Understanding the factors contributing to PPD is essential for developing effective interventions. This study aimed to investigate the relationship between social support and postpartum depression symptoms, with a focus on the mediating role of emotion regulation difficulties. Methods: A sample of 160 postpartum women (M age = 33.57, SD = 4.94) participated in the study. Participants were assessed on their levels of perceived social support, difficulties in emotion regulation, and symptoms of PPD. Results: The results indicated that lower levels of social support were significantly associated with greater difficulties in emotion regulation (effects ranging from -0.10 to 0.07). These difficulties in turn were linked to higher levels of postpartum depression symptoms (effects ranging from -0.29 to 0.78), suggesting a partial mediation effect from emotional awareness (95% CI -0.05, -0.00), non-acceptance of emotions (95% CI -0.04, -0.00), difficulty in goal-directed behavior (95% CI -0.04, -0.00), and limited access to strategies (95% CI -0.12, -0.04). Conclusions: These findings underscore the critical role of both social support and emotion regulation in the development of PPD symptoms. Enhancing emotion regulation skills, particularly for women with limited social support, could be a key target for interventions aimed at reducing the risk and severity of PPD.

Low Social Support is Associated With Postpartum Depression Symptoms Among Illinois Postpartum Women

BACKGROUND

Postpartum depression (PPD) occurs after delivery, with severity and onset varying by individual. Women with low social support may be at higher risk for PPD. This study examined the association between social support and self-reported postpartum depression symptoms (PDS) among Illinois postpartum women.

METHODS

Using 2016-2020 data from the Illinois Pregnancy Risk Assessment Monitoring System (PRAMS) (n = 5886), instrumental support (physical, hands-on support) and partner emotional support were each categorized as high/low and were combined in a composite measure (high = high on both types, moderate = high on one type, and low = low on both types). PDS were self-reported. Crude and adjusted odds ratios (aOR) and 95% confidence intervals (CI) were calculated using logistic regression.

RESULTS

Overall, 9.6% (95% CI = 8.8-10.4) of Illinois postpartum women experienced PDS. Of Illinois postpartum women, 63.5% (95% CI = 62.1-64.9) had high composite support, 29.3% (95% CI = 28.0-30.6) had moderate composite support, and 7.1% (95% CI = 6.4-7.9) had low composite support. After adjustment for maternal characteristics, instrumental support, partner emotional support, and a composite measure of support were each significantly associated with PDS. Compared to women with high composite support, women with low composite support had six times the odds of PDS (aOR = 6.1, 95% CI = 4.5-8.2), and women with moderate composite support had nearly three times the odds of PDS (aOR = 2.7, 95% CI = 2.2-3.4).

CONCLUSION

PDS was associated with instrumental support, partner emotional support, and a composite measure of support in Illinois postpartum women. This suggests the importance of addressing social support for postpartum individuals.

Leading Stressors and Coping Strategies Associated With Maternal Physical and Mental Health During the Extended Postpartum Period

INTRODUCTION

A critical gap exists in understanding stressors and coping that affect women's health beyond 6 weeks postpartum. Using new stressor and coping scales tailored to postpartum women, we examined the relationship of postpartum-specific stressors and coping to women's physical and mental health between 2 to 22 months after childbirth.

METHODS

A total of 361 women of diverse race, ethnicity, and functional abilities recruited through clinical and online methods completed online surveys that included Sources of Stress-Revised subscales, such as overload, changes after pregnancy, and low support resources; Postpartum Coping Scale subscales, such as self-regulation, self-care, and health promotion; Patient-Reported Outcomes Measurement Information System Global Health, covering physical and mental health dimensions; and social demographic items. Analyses included hierarchical linear regression models adjusted for social factors.

RESULTS

Education and employment were the only social factors associated with physical and mental health, respectively. After adjusting for social factors, overload (P < .001) and coping through health promotion (P = .020) were the only additional variables associated with physical health. After adjusting for social factors, overload (P < .001) and low support resources (P = .002) and coping through self-care (P = .036) were the only additional variables associated with mental health. Thus, being overloaded was the key stressor associated with decreases in physical and mental health. Health promotion was associated with increases in physical health, and self-care was associated with increases in mental health.

DISCUSSION

These findings point to directions for health care and community interventions to promote health for postpartum women under stress. Strengths of our study include application of stress and coping scales tailored to postpartum women, whereas a limitation is use of a cross-sectional design.

Per- and polyfluoroalkyl substances (PFAS), perceived stress, and depressive symptoms in a prospective cohort study of black women

BACKGROUND

Per- and polyfluoroalkyl substances (PFAS) are endocrine-disrupting chemicals with neurotoxic properties. PFAS have been associated with depressive symptoms among women in some studies, but little research has evaluated the effects of PFAS mixtures. Further, no study has investigated interactions of PFAS-depression associations by perceived stress, which has been shown to modify the effects of PFAS on other health outcomes.

OBJECTIVE

In a prospective cohort study of reproductive-aged Black women, we investigated associations between PFAS and depressive symptoms and the extent to which perceived stress modified these associations.

METHODS

We analyzed data from 1499 participants (23-35 years) in the Study of Environment, Lifestyle, and Fibroids. We quantified concentrations of nine PFAS in baseline plasma samples using online solid-phase extraction-liquid chromatography-isotope dilution tandem mass spectrometry. Participants reported perceived stress via the Perceived Stress Scale (PSS-4; range = 0-16) at baseline and depressive symptoms via the Center for Epidemiologic Studies Depression Scale (CESD; range = 0-44) at the 20-month follow-up visit. We used Bayesian Kernel Machine Regression to estimate associations between PFAS concentrations, individually and as a mixture, and depressive symptoms, and to assess effect modification by PSS-4 scores, adjusting for confounders.

RESULTS

Baseline perfluorodecanoic acid concentrations were associated with greater depressive symptoms at the 20-month follow-up, but associations for other PFAS were null. The PFAS were not associated with depressive symptoms when evaluated as a mixture. The association between the 90th percentile (vs. 50th percentile) of the PFAS mixture with CES-D scores was null at the 10th (β = 0.03; 95 % CrI = 0.20, 0.25), 50th (β = 0.02; 95 % CrI = -0.16, 0.19), and 90th (β = 0.01; 95 % CrI = 0.18, 0.20) percentiles of PSS-4 scores, suggesting perceived stress did not modify the PFAS mixture.

CONCLUSION

In this prospective cohort study, PFAS concentrations-assessed individually or as a mixture-were not appreciably associated with depressive symptoms, and there was no evidence of effect modification by perceived stress.

The effect of antepartum depressive and anxiety symptoms on mother-infant interaction: The mediating role of antepartum maternal emotional stress

Anxiety disorders, depression, and emotional stress during the antepartum period are interlinked with adverse child development. The quality of the dyadic interaction seems to play a crucial role in the transmission of these effects. In this study, we explored the mediating effect of antepartum maternal emotional stress (assessed via the Prenatal Emotional Stress Index) regarding the relationship of antepartum maternal depressive (assessed via the Edinburgh Postpartum Depression Scale), anxiety symptoms (assessed via the Stat-Trait-Anxiety-Inventory), and depressive and anxiety disorders (assessed according to the DSM-IV-TR) in the antepartum period on postpartum interactive quality in a longitudinal design. The Face-to-Face-Still-Face Paradigm (FFSF) and the Infant and Caregiver Engagement Phases (ICEP-R) coding system were used to assess the postpartum interactive qualities of the mother-infant dyads. The sample consisted of 59 women, 38 in the clinical and 21 in the control group. We found significant indirect effects of antepartum depressive symptoms and maternal diagnostic status on the mother's neutral engagement and on the latency to the first social positive interactive match during the interaction - effects that were mediated by antepartum stress. Moreover, there was an indirect effect of state anxiety on neutral engagement - mediated by antepartum stress. Therapeutic intervention studies focusing on maternal antepartum regulation of emotional stress and postpartum interactive patterns might be crucial to encounter maladaptive developmental trajectories.

Spousal support and dyadic adjustment in the early postpartum period

In the study, we aimed to investigate the effects of perceived spousal support and dyadic adjustment on the psychological well-being of women in the early postpartum period. This descriptive and correlational study consisted of 367 women giving birth in the postpartum department between 15th July and 31st October 2022. The data were collected using the Personal Information Form, the Perceived Spousal Support Among Women in Early Postpartum Period (PSSAWEPP), the Revised Dyadic Adjustment Scale (RDAS), and the Psychological Well-Being Scale (PWBS). The average scores of PSSAWEPP, RDAS, and PWBS in the mothers were found as 61.79 ± 7.73, 54.16 ± 6.28, and 45.87 ± 5.74, respectively. The elevated scores of perceived spousal support (β = 0.234, p < .001) and dyadic adjustment (β = 0.270, p < .001) of women led to a significant increase in the level of psychological well-being. In conclusion, the support received by women from spouses and dyadic adjustment affect the psychological well-being of women in the early postpartum period.

The role of stress in perinatal depression and anxiety - A systematic review

Perinatal depression (PND) and anxiety affect around 20% of women, but available pharmacotherapy is not sufficiently effective in 20-60% of them, indicating a need for better understanding of these diseases. Since stress is a significant risk factor for PND, the aim was to examine the role of biological, environmental and psychological stress in PND and anxiety through a systematic literature search. Overall 210 studies were included, among which numerous rodent studies showed that perinatal stress induced depressive-like and anxious behavior, which was associated with HPA-axis alterations and morphological brain changes. Human studies indicated that the relationship between cortisol and perinatal depression/anxiety was not as clear and with many contradictions, although social and psychological stress were clearly positively associated with PND. Finally, oxytocin, synthetic neuroactive steroid and n-3 PUFA diet have been identified as potentially beneficial in the therapy of PND and anxiety, worth to be investigated in the future.

Mitochondrial might: powering the peripartum for risk and resilience

The peripartum period, characterized by dynamic hormonal shifts and physiological adaptations, has been recognized as a potentially vulnerable period for the development of mood disorders such as postpartum depression (PPD). Stress is a well-established risk factor for developing PPD and is known to modulate mitochondrial function. While primarily known for their role in energy production, mitochondria also influence processes such as stress regulation, steroid hormone synthesis, glucocorticoid response, GABA metabolism, and immune modulation - all of which are crucial for healthy pregnancy and relevant to PPD pathology. While mitochondrial function has been implicated in other psychiatric illnesses, its role in peripartum stress and mental health remains largely unexplored, especially in relation to the brain. In this review, we first provide an overview of mitochondrial involvement in processes implicated in peripartum mood disorders, underscoring their potential role in mediating pathology. We then discuss clinical and preclinical studies of mitochondria in the context of peripartum stress and mental health, emphasizing the need for better understanding of this relationship. Finally, we propose mitochondria as biological mediators of resilience to peripartum mood disorders.

Postpartum stress in the first 6 months after delivery: a longitudinal study in Nantong, China

OBJECTIVES

The objective is to to explore the longitudinal change trajectories of postpartum stress and its related factors.

DESIGN

A longitudinal study with follow-ups from 42 days to 6 months after delivery.

SETTINGS AND PARTICIPANTS

A total of 406 postpartum women were recruited at baseline (42 days after delivery) from 6 hospitals in Nantong, Jiangsu Province, China, and followed up at 3 and 6 months. After the follow-ups, 358 postpartum women were retained for further analysis.

METHODS

Postpartum stress was evaluated using the Maternal Postpartum Stress Scale (MPSS) at baseline (42 days) and 3 and 6 months after delivery. MPSS has three dimensions, such as: personal needs and fatigue, infant nurturing and body changes and sexuality. Postpartum depression and anxiety were measured using the Edinburgh Postnatal Depression Scale and the short-form Depression, Anxiety and Stress Scale, respectively. The MPSS scores were normalised using a rank-based inverse normal transformation.

RESULTS

Postpartum stress decreased significantly after 3 months, and postpartum stress reduced further after 6 months. Additionally, the scores for all three dimensions reduced after 6 months, while infant nurturing reduced after both 3 and 6 months. Older age (β=0.028, p=0.049), higher education level (β=0.153, p=0.005) and higher body mass index (BMI) (β=0.027, p=0.008) of the postpartum women were significantly associated with higher postpartum stress levels in corresponding dimensions at 42 days. Older age was also associated with higher postpartum stress at 3 (β=0.030, p=0.033) and 6 months (β=0.050, p<0.001) in the dimension of personal needs and fatigue. Postpartum stress levels were significantly higher in women with depression or anxiety symptoms.

CONCLUSIONS

Postpartum stress continuously declined from 42 days to 6 months after delivery. Postpartum women with older age, higher education levels, higher BMI and anxiety or depression symptoms should be the target population for early intervention.

The effect of perceived social support on postpartum stress: the mediating roles of marital satisfaction and maternal postnatal attachment

BACKGROUND

Multiple factors may be responsible for the development of postpartum stress, including perceived social support, marital satisfaction, and maternal postnatal attachment. However, the underlying mediation mechanisms remain unclear. This study examined the complex relationships between perceived social support and postpartum stress among Chinese women.

METHODS

A convenience sample comprising 406 postpartum women was recruited from six hospitals in Nantong, Jiangsu Province, China. The participants completed general survey questionnaires and were evaluated using the Maternal Postpartum Stress Scale, the Perceived Social Support Scale, the Maternal Postnatal Attachment Scale, and the Marital Satisfaction Scale. Furthermore, we evaluated the relationship between postpartum stress and the various influencing factors by performing a multiple linear regression analysis. The potential mediating roles of marital satisfaction and maternal and infant attachment in the association between perceived social support and postpartum stress were explored by performing a mediation analysis.

RESULTS

According to the multivariate regression analysis, perceived social support, marital satisfaction, and maternal postnatal attachment contributed to postpartum stress levels (P < 0.05). The mediation analysis revealed that marital satisfaction and maternal postnatal attachment played parallel mediating roles in the association between perceived social support and postpartum stress, and the mediating effect of marital satisfaction was - 0.1125 (95% confidence interval [CI]: -0.1784 to -0.0520), accounting for 33.20% of the total effect, and the mediating effect of maternal postnatal attachment was - 0.0847 (95% CI: -0.1304 to -0.0438), accounting for 25.00% of the total effect.

CONCLUSION

Our study revealed that perceived social support could influence postpartum stress not only through direct effect (41.80% of the total effect), but also through the indirect effect (mediation effect) of marital satisfaction and maternal postnatal attachment (58.20% of the total effect), suggesting that improving postpartum women's social support, enhancing maternal and infant attachment, and improving their marital satisfaction could help lower postpartum stress.

A longitudinal study of perinatal depression and the risk role of cognitive fusion and perceived stress on postpartum depression

AIMS AND OBJECTIVES

To explore fluctuations in perinatal depression based on physiological, psychological and interpersonal dimensions to analyse risk factors across three time points: in the third trimester and at weeks 1 and 6 postpartum.

BACKGROUND

Pregnant women experience depression at multiple time points and require screening. Studies have shown protective and negative factors related to postpartum depression. Cognitive fusion refers to an individual's emotions and behaviours that are regulated and influenced by that individual's own cognitive overregulation, especially when facing stress. This is an important psychological factor related to depression, but little is known about it in pregnant women.

DESIGN

A longitudinal study was conducted from June 2019-July 2020, and the findings are reported following the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

METHODS

Pregnant women (n = 207) were recruited, and a questionnaire survey was performed at 32-34 weeks of pregnancy and at weeks 1 and 6 postpartum. Repeated-measures analysis of variance was performed to analyse the changes in depression over time. Regression analysis and linear mixed modelling were used to identify risk factors. Pearson's correlation analysis was performed to analyse the relationships between variables.

RESULTS

Of the pregnant women, 36.70% experienced antenatal depression and prolonged depression with the onset of postpartum depression (12.21%). Some depressive moods disappeared spontaneously after delivery (47.37%). Perceived stress was the highest risk predictor of postpartum depression (β = 0.332), followed by cognitive fusion (β = 0.178), which remained stable over time and might have been positively related to having a vulnerable personality (0.2 < r < 0.4). Social support plays a positive role in lowering postpartum depression (β = -0.027).

CONCLUSIONS

Changes in depression were influenced by multiple factors with stability and predictability across time. Psychological dimensions, such as perceived stress and cognitive fusion, are risk factors for developing postpartum depression and antenatal depression.

RELEVANCE TO CLINICAL PRACTICE

Pregnant women can be divided into depressive cohorts according to screening at different time points to provide targeted interventions.

Different Effects of Perceived Social Support on the Relationship between Perceived Stress and Depression among University Students with Borderline Personality Disorder Symptoms: A Multigroup Mediation Analysis

Background: While perceived social support can mediate the relationship between perceived stress and depression, little is known about the differences between individuals with high and low borderline personality disorder symptoms (BPDS). This study aimed to investigate the associations among perceived stress, perceived social support, and depression, and compare low and high levels of BPDS. Methods. This cross-sectional analysis was a secondary analysis of data from the SI-Bord study. University students across Thailand completed a screening instrument for borderline personality disorder, the Perceived Stress Scale (PSS), the Revised Thai Multi-dimensional Scales of Perceived Social Support (MSPSS), and the Patient-Health Questionnaire (PHQ)-9. Mediation analysis using PROCESS was applied to test the direct and indirect effects of perceived stress on depression. Multigroup mediational analysis was adopted to compare low and high levels of BPDS. Results. The mean age of the 330 participants was 20.27 (SD, 1.4) and 80% were female. Significant correlations were observed between the PSS, MSPSS, and PHQ scores, with greater magnitude among the high-level BPDS group (p < 0.001). A significant direct effect on perceived stress and a significant indirect effect on depression through perceived social support were noted. Of all the sources of social support, only the significant others variable significantly differed between the two groups (p < 0.05). Conclusion. Perception of social support had a significant mediating role in perceived stress and depression. The magnitude of associations was remarkably high for individuals with high BPDS compared to those with low BPDS. Unlike those with low BPDS, all sources of social support were significant mediators between the two groups.

Association of COVID-19 Lockdown during the Perinatal Period with Postpartum Depression: Evidence from Rural Areas of Western China

COVID-19 lockdown has posed unique challenges to postpartum women, but its association with postpartum depression is not well understood in the Global South. This study aims to evaluate the association between COVID-19 lockdown and postpartum depression in rural areas of western China. A multi-stage random cluster sampling method was used to select a cohort of pregnant and postpartum women with infants aged 0-6 months. We conducted an in-person survey before the COVID-19 lockdown and a phone survey right after the lockdown ended. We used multivariate regression models to evaluate the association between lockdown and postpartum depression. Subgroup analysis was performed to explore the role of social support. The overall prevalence of postpartum depression was 13.3%. Postpartum women who experienced the lockdown were less likely to be depressed than those who did not (adjusted odds ratio (aOR) = .43, 95% confidence interval (CI) = [.27, .70]). Lockdown was negatively associated with postpartum depression among postpartum women with low level of social support (aOR = .30, 95% CI = [.18, .51]). COVID-19 lockdown was associated with lower likelihood of postpartum depression, potentially due to increased support from family. Future research is needed to explore targeted interventions to prevent postpartum depression among women from migrant worker families in rural China.

Social connectedness as a determinant of mental health: A scoping review

Public health and epidemiologic research have established that social connectedness promotes overall health. Yet there have been no recent reviews of findings from research examining social connectedness as a determinant of mental health. The goal of this review was to evaluate recent longitudinal research probing the effects of social connectedness on depression and anxiety symptoms and diagnoses in the general population. A scoping review was performed of PubMed and PsychInfo databases from January 2015 to December 2021 following PRISMA-ScR guidelines using a defined search strategy. The search yielded 66 unique studies. In research with other than pregnant women, 83% (19 of 23) studies reported that social support benefited symptoms of depression with the remaining 17% (5 of 23) reporting minimal or no evidence that lower levels of social support predict depression at follow-up. In research with pregnant women, 83% (24 of 29 studies) found that low social support increased postpartum depressive symptoms. Among 8 of 9 studies that focused on loneliness, feeling lonely at baseline was related to adverse outcomes at follow-up including higher risks of major depressive disorder, depressive symptom severity, generalized anxiety disorder, and lower levels of physical activity. In 5 of 8 reports, smaller social network size predicted depressive symptoms or disorder at follow-up. In summary, most recent relevant longitudinal studies have demonstrated that social connectedness protects adults in the general population from depressive symptoms and disorders. The results, which were largely consistent across settings, exposure measures, and populations, support efforts to improve clinical detection of high-risk patients, including adults with low social support and elevated loneliness.

The enduring impact of birth: Women's birth perceptions, postpartum depressive symptoms, and postpartum depression risk

BACKGROUND

Postpartum depression (PPD) and related maternal mood disorders affect anywhere from 7% to 19% of postpartum women. Although historically a neglected issue, there has been a strong impetus in the past few decades to implement routine, universal screening and to address PPD as a major public health concern. Still, there has been relatively little analysis of how the quality of the birth experience influences subsequent maternal mental health. We examine the relationship between perceived birth experience and two PPD screeners (Edinburgh Postnatal Depression Scale and Postpartum Depression Screening Scale).

METHODS

Data came from waves I and II of the Listening to Mothers data set. This is the only national survey of US women's childbirth and postpartum experiences. In logistic and linear regression models, we used a 12-item "feeling" index (perceived birth experience) to predict (a) overall PPD screener scores, and (b) likelihood of meeting the clinical cutoff for depression risk. We also controlled for other known socio-demographic and obstetric risk factors.

RESULTS

Perceived birth experience strongly and consistently predicted both PPD screener measures, and in both forms-raw scores and clinical cutoffs. By contrast, other known risk factors had inconsistent results across the two screeners.

DISCUSSION

Perceived birth experience should be considered more central in assessing PPD. It may also be more robust than the PPD screeners used in practice, and therefore, could be a more reliable predictor of PPD. Providers should consider how the improved social-psychological quality of women's birth experience can act as a buffer to PPD and other postpartum concerns.

Maternal Stressors and Coping Strategies During the Extended Postpartum Period: A Retrospective Analysis with Contemporary Implications

Background: Despite recent emphasis on the "fourth trimester" and beyond, most knowledge of stressors affecting women is focused on the first 6 postpartum weeks. Our aim was to identify postpartum-specific stressors and coping over the extended postpartum period. Methods: We analyzed data from two surveys for a combined sample of 346 postpartum women. Principal components analysis of survey items on sources of stress was used to identify categories of postpartum-specific stressors. Content analysis was used to categorize text data on coping strategies. Results: Seven stressors were identified: Overload, Working mother concerns, Isolated motherhood, Limited supportive resources, Exhaustion, Parenting demands, and Changes in body and sexuality. Overload was the most frequent stressor (F = 49.32, p < 0.001) and was significantly higher at 9-12 months than at 5-8 months or at 13 months or more (F = 6.42, p = 0.002). Fulltime employment and having more than one child were associated with elevated scores on several stressors. Content analysis yielded seven coping strategies, such as Take time alone or with others, Manage emotions and thoughts, and Maintain a manageable workload. Five of the seven stressors were associated with at least one of the top five coping strategies; none was associated with Overload or Limited supportive resources. Conclusions: Women's predominant source of stress was from overload and was highest at 9 to 12 months postpartum. Community resources and public health policy and programming are needed to prepare and support women during the challenging first postpartum year.

Biological, Psychological, and Social Determinants of Depression: A Review of Recent Literature

Depression is one of the leading causes of disability, and, if left unmanaged, it can increase the risk for suicide. The evidence base on the determinants of depression is fragmented, which makes the interpretation of the results across studies difficult. The objective of this study is to conduct a thorough synthesis of the literature assessing the biological, psychological, and social determinants of depression in order to piece together the puzzle of the key factors that are related to this condition. Titles and abstracts published between 2017 and 2020 were identified in PubMed, as well as Medline, Scopus, and PsycInfo. Key words relating to biological, social, and psychological determinants as well as depression were applied to the databases, and the screening and data charting of the documents took place. We included 470 documents in this literature review. The findings showed that there are a plethora of risk and protective factors (relating to biological, psychological, and social determinants) that are related to depression; these determinants are interlinked and influence depression outcomes through a web of causation. In this paper, we describe and present the vast, fragmented, and complex literature related to this topic. This review may be used to guide practice, public health efforts, policy, and research related to mental health and, specifically, depression.

A Chain Mediation Model of Perceived Stress, Neuroticism, and Psychological Inflexibility on Depressive Symptoms of Chinese New Fathers

There is a growing concern about mental health issues in new fathers, such as postpartum depression (PPD). Factors associated with PPD in men include personality traits and perceived stress. This study examined a set of hypothesized paths using perceived stress, neuroticism, and psychological inflexibility to predict depressive symptoms. A total of 189 participants took part. The mean age of these first-time fathers was 36.12 years (SD = 2.39). Perceived stress, neuroticism, and psychological inflexibility positively predicted new fathers’ depressive symptoms (B = 0.13, 0.37, and 0.31, respectively). These predictors explained 48% (R² = 0.48) of the variance in the measured outcome of depressive symptoms in these new Chinese fathers. The total standardized direct effects of the three variables on depressive symptoms were 0.47 (95% CI [0.38, 0.53]). In conclusion, this study provides novel information about the chain mediating role played by neuroticism and psychological inflexibility in the relationship between perceived stress and PPD. Perceived stress significantly predicted neuroticism and psychological inflexibility, which in turn significantly predicted depressive symptoms in new Chinese fathers. The relationship between perceived stress and depressive symptoms was also mediated by each of psychological inflexibility or neuroticism alone.

Pre-delivery angiogenic factors and their association with peripartum perceived stress and pain in pre-eclampsia with severe features and normotensive pregnancies

OBJECTIVE

To determine if any of maternal pre-delivery soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PIGF), or sFlt-1/PIGF ratio correlate with either perceived stress scale (PSS) or verbal numeric rating scale (VNRS) pain scores.

METHODS

Among 50 pregnant women with severe pre-eclampsia and 90 normotensive pregnant women observed from 48 h or less before delivery until day 3 postpartum, correlations between the following were performed: (1) serum concentrations of each angiogenic factor (sFlt-1, PIGF, and sFlt-1/PIGF ratio) sampled within 48 h before childbirth and a four-item PSS (pre-delivery and one-off 48-72 h postpartum score); (2) the same angiogenic factors above and VNRS ranging from 0 to 10; and (3) PSS and VNRS (both pre-delivery and postpartum).

RESULTS

In the normotensive group, there was a positive correlation between sFlt-1 and postpartum PSS (ρ +0.214 and P = 0.043), and between sFlt-1/PIGF ratio and postpartum PSS (ρ +0.213 and P = 0.044). In the normotensive and severe pre-eclampsia groups there were non-significant negative correlations between PIGF and postpartum PSS (P > 0.096) and non-significant positive correlations between pre-delivery PSS and pre-delivery VNRS (P > 0.053). Other correlations were uninformative.

CONCLUSION

Maternal pre-delivery sFlt-1/PIGF ratio in normotensive pregnancy is a promising biomarker for identifying risk of increased postpartum PSS to enable early counselling.

Perceived social support and postpartum depression symptoms across geographical contexts: Findings from the 2016 Ohio Pregnancy Assessment survey

BACKGROUND

The purpose of this study was to examine the association between perceived social support and postpartum depression symptoms (PDS) and to understand how this association may differ for urban, suburban, rural Appalachian, and rural non-Appalachian women in Ohio.

METHODS

Data were obtained via the 2016 Ohio Pregnancy Assessment Survey (n = 3382), a representative sample of postpartum women in Ohio. We conducted bivariate analyses to assess the associations between self-perceived social support and PDS, and covariates. Univariate and multivariate logistic regressions were conducted using a modified Poisson distribution to estimate the association between social support and PDS, adjusting for sociodemographic characteristics. We also examined geographical context as an independent predictor of PDS and as an effect modifier for the association between social support and PDS.

RESULTS

15.6% of survey respondents experienced PDS. Women with low levels of social support had slightly higher prevalence (aPR: 1.4, 95% CI: 1.0-2.1) of PDS compared to women with high social support. Geographic context was an independent predictor of PDS; women in rural Appalachia had significantly lower prevalence (aPR: 0.5, 95% CI: 0.2-0.9) of PDS compared to women in urban areas. We did not find that geographical context modified the relationship between social support and PDS (Wald P = .5).

CONCLUSIONS

Low social support was associated with increased PDS but did not reach statistical significance. Women living in rural Appalachia had a lower prevalence of PDS. Future studies should explore the reasons for lower rates of PDS in rural Appalachia.

Psychosocial status modifies the effect of maternal blood metal and metalloid concentrations on birth outcomes

BACKGROUND

Metal exposure and psychosocial stress in pregnancy have each been associated with adverse birth outcomes, including preterm birth and low birth weight, but no study has examined the potential interaction between them.

OBJECTIVES

We examined the modifying effect of psychosocial stress on the association between metals and birth outcomes among pregnant women in Puerto Rico Testsite for Exploring Contamination Threats (PROTECT) birth cohort study.

METHODS

In our analysis of 682 women from the PROTECT study, we measured 16 essential and non-essential metals in blood samples at two time points. We administered questionnaires to collect information on depression, perceived stress, social support, and life experience during pregnancy. Using K-means clustering, we categorized pregnant women into one of two groups: "good" and "poor" psychosocial status. We then evaluated whether the effect of blood metals (geometric average) on adverse birth outcomes (gestational age, preterm birth [overall and spontaneous], birth weight z-score, small for gestation [SGA], large for gestation [LGA]) vary between two clusters of women, adjusting for maternal age, maternal education, pre-pregnancy body mass index (BMI), and second-hand smoke exposure.

RESULTS

Blood manganese (Mn) was associated with an increased odds ratio (OR) of overall preterm birth (OR/interquartile range [IQR] = 2.76, 95% confidence interval [CI] = 1.25, 6.12) and spontaneous preterm birth (OR/IQR: 3.68, 95% CI: 1.20, 6.57) only among women with "poor" psychosocial status. The association between copper (Cu) and SGA was also statistically significant only among women having "poor" psychosocial status (OR/IQR: 2.81, 95% CI: 1.20, 6.57). We also observed associations between nickel (Ni) and preterm birth and SGA that were modified by psychosocial status during pregnancy.

CONCLUSIONS

Presence of "poor" psychosocial status intensified the adverse associations between Mn and preterm birth, Cu and SGA, and protective effects of Ni on preterm. This provides evidence that prenatal psychosocial stress may modify vulnerability to metal exposure.

A Comprehensive Conceptual Framework to Guide Clinical Practice and Research About Mental Health During the Perinatal Period

Perinatal mood and anxiety disorders (PMADs) affect up to 20% of pregnant and postpartum women and can have negative sequelae for maternal-child health. Nurses with clinical and research roles are on the front line of efforts to assess for and assist with prevention and intervention with PMAD symptoms. Thus, they can play an essential role in enhancing the mental well-being of women in the perinatal period and maternal-child health outcomes. The aim of this article is to assist nurses in this work by outlining the Comprehensive Model of Mental Health during the Perinatal Period, a conceptual framework for considering clinical and research opportunities to enhance perinatal mental health. The framework uses key principles that recognize biopsychoneuroimmunologic mechanisms involved in mental health; the key role that the experience of matrescence ("becoming a mother") plays in mental health and maternal-child health; and the mother-infant dyad as the functional unit during the perinatal period. Examples are provided of how the key principles of this framework might be used to enhance research and clinical practice about PMADs and, ultimately, enhance maternal-child health outcomes.
