What If Pregnancy Is Not Seventh Heaven? The Influence of Specific Life Events during Pregnancy and Delivery on the Transition of Antenatal into Postpartum Anxiety and Depression

Stress and anxiety during pregnancy and length of gestation: a federated study using data from five Canadian and European birth cohorts

While its etiology is not fully elucidated, preterm birth represents a major public health concern as it is the leading cause of child mortality and morbidity. Stress is one of the most common perinatal conditions and may increase the risk of preterm birth. In this paper we aimed to investigate the association of maternal perceived stress and anxiety with length of gestation. We used harmonized data from five birth cohorts from Canada, France, and Norway. A total of 5297 pregnancies of singletons were included in the analysis of perceived stress and gestational duration, and 55,775 pregnancies for anxiety. Federated analyses were performed through the DataSHIELD platform using Cox regression models within intervals of gestational age. The models were fit for each cohort separately, and the cohort-specific results were combined using random effects study-level meta-analysis. Moderate and high levels of perceived stress during pregnancy were associated with a shorter length of gestation in the very/moderately preterm interval [moderate: hazard ratio (HR) 1.92 (95%CI 0.83, 4.48); high: 2.04 (95%CI 0.77, 5.37)], albeit not statistically significant. No association was found for the other intervals. Anxiety was associated with gestational duration in the very/moderately preterm interval [1.66 (95%CI 1.32, 2.08)], and in the early term interval [1.15 (95%CI 1.08, 1.23)]. Our findings suggest that perceived stress and anxiety are associated with an increased risk of earlier birth, but only in the earliest gestational ages. We also found an association in the early term period for anxiety, but the result was only driven by the largest cohort, which collected information the latest in pregnancy. This raised a potential issue of reverse causality as anxiety later in pregnancy could be due to concerns about early signs of a possible preterm birth.

Stressful life events, oral health, and barriers to dental care during pregnancy

OBJECTIVES

Poor oral health during pregnancy poses risks to maternal and infant well-being. However, limited research has documented how proximate stressful life events (SLEs) during the prenatal period are associated with oral health and patterns of dental care utilization.

METHODS

Data come from 13 states that included questions on SLEs, oral health, and dental care utilization in the Pregnancy Risk Assessment Monitoring System for the years 2016-2020 (n = 48,658). Multiple logistic regression analyses were used to assess the association between levels of SLE (0, 1-2, 3-5, or 6+) and a range of (1) oral health experiences and (2) barriers to dental care during pregnancy while controlling for socio-demographic and pregnancy-related characteristics.

RESULTS

Women with more SLEs in the 12 months before birth-especially six or more-reported worse oral health experiences, including not having dental insurance, not having a dental cleaning, not knowing the importance of caring for teeth and gums, needing to see a dentist for a problem, going to see a dentist for a problem, and unmet dental care needs. Higher levels of SLEs were also associated with elevated odds of reporting barriers to dental care.

CONCLUSIONS

SLEs are an essential but often understudied risk factor for poor oral health, unmet dental care needs, and barriers to dental care services. Future research is needed to understand better the mechanisms linking SLEs and oral health.

The prevalence and associated factors of prenatal depression and anxiety in twin pregnancy: a cross-sectional study in Chongqing, China

Background

Pregnant women expecting twins are more likely to experience stress, which can lead to anxiety and depression. Our aim was to investigate the prevalence of prenatal anxiety and depressive symptoms in women with twin pregnancies and the associated factors.

Methods

In a cross-sectional survey, 210 women with twin pregnancies who satisfied the inclusion and exclusion criteria in two tertiary centers in Southwestern China were asked to complete a basic information form, the Self-Rating Anxiety Scale (SAS) and the Self-Rating Depression Scale (SDS). To compare statistics with normal distribution in distinct characteristic groups, a paired t-test, and one-way ANOVA were utilized. Binary logistic step regression was used to analyze the associated factors of antenatal anxiety and depressive symptoms.

Results

The 210 women with twin pregnancies (age = 30.8 ± 4.2 years) were between 7 and 37 gestational weeks (29.2 ± 1.2 weeks), were typically well-educated (72.4% had a post-high-school degree), and reasonably affluent (88.1% were above the low-income cutoff). Among them, 34.8% had symptoms associated with clinical levels of anxiety, and 37.1% had symptoms indicating possible depression. The prevalence of co-morbid anxiety and depressive symptoms was 24.3%. Binary stepwise logistic regression analysis showed that previous health status and sleep disturbance during pregnancy were the associated factors of anxiety symptoms in women with twin pregnancies (P < 0.05), whereas age, previous health status, negative life events, and physical activity during pregnancy were the associated factors of depressive symptoms in women with twin pregnancies (P < 0.05).

Conclusion

About one-third of women with twin pregnancies had symptoms of anxiety or depression; these were most strongly predicted by some modifiable factors, suggesting that early preventive mind-body interventions may be a promising strategy to protect against mental health issues for women with twin pregnancies.

Prenatal stress from the COVID-19 pandemic predicts maternal postpartum anxiety as moderated by psychological factors: The Australian BITTOC Study

BACKGROUND

While there have been reports of increased perinatal anxiety during the COVID-19 pandemic (Stepowicz et al., 2020), there has been a lack of research on the relative importance of objective hardship and subjective distress. In this study, we explored the extent to which resilience, tolerance of uncertainty, and cognitive appraisal of the pandemic's consequences moderate the effect of prenatal objective hardship and subjective distress due to the pandemic on 2-month postpartum anxiety.

METHODS

Data were collected as part of the Birth in the Time of COVID (BITTOC) study. We measured objective hardship and subjective distress, mental health, and potential psychological moderators in 419 pregnant women residing in Australia, and at two months postpartum. Hierarchical multiple regressions were used.

RESULTS

Objective hardship and subjective distress independently predicted postpartum anxiety. All three psychological factors moderated the effect of objective hardship on anxiety. For women with low/neutral resilience, or low/moderate tolerance of uncertainty, or a negative cognitive appraisal, greater objective hardship predicted higher postpartum anxiety. Conversely, for women with high resilience, or high tolerance of uncertainty, or neutral/positive cognitive appraisal, there was no association. Only a neutral/positive cognitive appraisal significantly buffered the effect of subjective distress on anxiety.

LIMITATIONS

Participants self-selected themselves into the study. The generalizability of our results could be restricted to women of higher socio-economic status.

CONCLUSIONS

These findings help us better understand options for intervention and assessment of vulnerable women during times of stress, along with the mechanisms by which COVID-related stress during pregnancy contributes to postpartum anxiety.

A qualitative analysis of feelings and experiences associated with perinatal distress during the COVID-19 pandemic

Background

Rates of perinatal mental health difficulties (experienced during pregnancy and the 12-months postpartum) increased worldwide during the COVID-19 pandemic. In the UK, anxiety and depression were estimated to affect more than half of perinatal women during the first national lockdown. However, little is known about women’s qualitative experiences of distress. This study aimed to extend published quantitative findings resulting from the same data set (Harrison et al., Women Birth xxxx, 2021;  Harrison et al., J Reprod Infant Psychol 1–16, 2021) to qualitatively explore: 1) the feelings and symptoms associated with maternal perinatal distress during the COVID-19 pandemic; and 2) the associated sources of distress.

Methods

As part of an online survey during May 2020, 424 perinatal women responded to an open-ended question regarding a recent experience of distress. Qualitative data were analysed using an initial content analysis, followed by an inductive thematic analysis adopting a realist approach. Data were explored in the context of self-reported perinatal anxiety and depression symptoms.

Results

Initial content analysis of the data identified twelve distinct categories depicting participants’ feelings and symptoms associated with psychological distress. Despite the high rates of probable depression in the sample, women’s descriptions were more indicative of anxiety and general distress, than of symptoms traditionally related to depression. In terms of the associated psychosocial stressors, a thematic analysis identified five themes: Family wellbeing; Lack of support; Mothering challenges; Loss of control due to COVID-19; and Work and finances. Unsurprisingly given the context, isolation was a common challenge. Additionally, psychological conflict between maternal expectations and the reality of pregnancy and motherhood, loss of autonomy and control, and fears surrounding family health, safety, and wellbeing underlay many of the themes.

Conclusions

This study presents an array of feelings and symptoms expressed by perinatal mothers which may be useful to consider in relation to perinatal wellbeing. Furthermore, our data highlights several common sources of distress, including multiple COVID-19 specific factors. However, many were related to more general perinatal/maternal experiences. Our findings also point to considerations that may be useful in alleviating distress in pregnancy and early motherhood, including social support, realistic perinatal/maternal expectations, and support for those with perceived perinatal trauma.

How do prenatal people describe their experiences with anxiety? a qualitative analysis of blog content

Background

Despite elevated prevalence rates of prenatal (antenatal) anxiety across studies (13–21%), and prenatal people’s use of the Internet to search for pregnancy-related information and support, research investigating prenatal people’s experiences with online mental health communication, such as blogs, is lacking. This study examined blog entries focused on anxiety in pregnancy to better understand prenatal people’s Internet discourse concerning their experiences with anxiety.

Methods

A Google search using the keywords “anxiety,” “pregnant,” and “blog” resulted in N = 18 blogs that met inclusion criteria (public blog written in English describing a personal experience with prenatal anxiety in 250 words or more). Blog content was analyzed using a thematic analytic approach based on grounded theory principles.

Results

Three main themes capturing prenatal people’s experiences with anxiety as written in public blog content were developed from qualitative analyses: 1) etiology (subthemes: before pregnancy, during the current pregnancy, related to a previous pregnancy), 2) triggers (subthemes: uncertainty, perceived lack of control, and guilt and shame for not having a normal pregnancy), and 3) symptoms (subthemes: intertwined emotional, cognitive and physical symptoms, in addition to behavioural symptoms).

Conclusions

Our findings demonstrate a need for perinatal professionals to address anxiety symptoms and triggers in pregnancy. One way to address this may be by providing credible information regarding prenatal mental and physical health to pregnant people through online mediums, such as blogs. Bloggers often discussed experiencing a combination of emotional, cognitive, physical, and behavioural symptoms, which suggests that medical and mental health professionals should work collaboratively to provide care for prenatal people experiencing anxiety. Furthermore, Cognitive Behavioural Therapy (CBT) addresses these types of symptoms, which suggests that interventions developed or adapted to meet this populations’ needs could employ this therapeutic approach. Future research should explore the reasons why prenatal people experiencing anxiety engage with blogs, the characteristics of bloggers and readers, the impact of the blogging experience on both the blogger and their audience, and the information quality of blog content.

Prenatal witness stress induces intergenerational anxiety-like behaviors and altered gene expression profiles in male mice

Prenatal cues imposed on an organism can exert long-term and even cross-generational influences on the physiology and behaviors. To date, numerous rodent models have been developed to mimic the effects of prenatal physical stress on offspring. Whether psychological stress during gestation exerts adverse influences on offspring remains investigated. Here, we report that prenatal witnessing the defeat process of the mated partner induces anxiety-like behaviors in F1 male, but not female offspring. These abnormal behaviors were not present in the F2 generation, indicating a sex-specific intergenerational effects. Genome-wide transcriptional profiling identified 71 up-regulated and 120 down-regulated genes shared in F0 maternal and F1 male hippocampus. F0 and F1 hippocampi also shared witness stress-sensitive and -resistant genes. Whole transcriptome comparison reveals that F1 dentate gyrus showed differential expression profiles from hippocampus. Few differentially expressed genes were identified in the dentate gyrus of F1 stress female mice, explaining why females were resistant to the stress. Finally, candidate drugs as the potential treatment for psychological stress were predicted according to transcriptional signatures, including the histone deacetylase inhibitor and dopamine receptor agonist. Our work provides a new model for better understanding the molecular basis of prenatal psychological stress, highlighting the complexity of stress and sex factors on emotion and behaviors.

Perinatal Behavioral Health, the COVID-19 Pandemic, and a Social Determinants of Health Framework

The United States has greater prevalence of mental illness and substance use disorders than other developed countries, and pregnant women are disproportionately affected. The current global COVID-19 pandemic, through the exacerbation of psychological distress, unevenly affects the vulnerable population of pregnant women. Social distancing measures and widespread closures of businesses secondary to COVID-19 are likely to continue for the foreseeable future and to further magnify psychosocial risk factors. We propose the use of a social determinants of health framework to integrate behavioral health considerations into prenatal care and to guide the implementation of universal and comprehensive psychosocial assessment in pregnancy. As the most numerous and well-trusted health care professionals, nurses are ideally positioned to influence program and policy decisions at the community and regional levels and to advocate for the full integration of psychosocial screening and behavioral health into prenatal and postpartum care as core components.

Maternal postpartum depression: risk factors, impacts, and interventions for the NICU and beyond

PURPOSE OF REVIEW

Postpartum depression (PPD) negatively impacts caregivers, infants, siblings, and entire families. Mothers with infants admitted to the neonatal intensive care unit (NICU) face additional risk for PPD, coupled with risk factors extending beyond a NICU admision. The novelty of this review is the focus on maternal PPD for mothers with infants admitted to the NICU. Interventions aimed at limiting and preventing PPD in this population include: prenatal and postpartum depression screening, PPD symptom awareness and monitoring, and trauma-informed care.

RECENT FINDINGS

PPD, the most frequent complication of childbirth, affects approximately 10-15% of mothers worldwide. Prevalence rates increase to 40% for mothers whose infant is admitted to the NICU. PPD can affect maternal and child health across the life course and predispose future generations to a myriad of developmental, psychosocial, and physical challenges. Prevalence rates are higher for racial and ethnic minorities, immigrant and refugee populations, and mothers in rural locations. Trauma-informed care is suggested at individual and organizational levels, leading to better care for those with and without previous trauma exposure.

SUMMARY

Increasing PPD symptom awareness, screening for PPD, and connections with resources should begin during prenatal visits. Care teams should discuss barriers to resources for mothers, children, and families to improve access and support.

The impact of prenatal stressful life events on adverse birth outcomes: A systematic review and meta-analysis

BACKGROUND

Stressful life events as important stressors have gradually been recognized as the potential etiology that may lead to adverse birth outcomes such as preterm birth (PTB), low birth weight (LBW), and small for gestational age (SGA). However, researches on this topic have shown relatively inconsistent results. This systematic review and meta-analysis was performed to synthesize available data on the association between prenatal stressful life events and increased risks of PTB, LBW, and SGA.

METHODS

Electronic databases were searched from their inception until September 2020. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were calculated to assess the association between prenatal stressful life events and PTB, LBW, and SGA using random effects models. In addition, subgroup analyses, cumulative meta-analyses, sensitivity analyses, and publication bias diagnosis were conducted. STATA 14.0 was applied for statistical analyses.

RESULTS

Totally 31 cohort studies involving 5,665,998 pregnant women were included. Prenatal stressful life events were associated with a 20% higher risk of PTB (RR = 1.20, 95%CI = 1.10-1.32), a 23% increased risk for LBW (RR = 1.23, 95%CI = 1.10-1.39), and a 14% higher risk of SGA (RR = 1.14, 95%CI = 1.08-1.20). Sensitivity analysis indicated the results were stable.

CONCLUSIONS

Findings indicated that pregnant women experiencing prenatal stressful life events were at increased risk of PTB, LBW, and SGA. This information provided additional supports that pregnant women experiencing prenatal stressful life events would benefit from receiving assessment and management in prenatal care services.
