A review and psychometric evaluation of pregnancy-specific stress measures

Effects of Mindfulness-Based Interventions on Cardiometabolic-Related Adverse Pregnancy Outcomes: A Systematic Review

BACKGROUND

Growing evidence suggests maternal stress contributes to the development of adverse pregnancy outcomes that are associated with cardiovascular and cardiometabolic risk in birthing persons. Mindfulness-based interventions may positively affect psychological stress in pregnancy and, in turn, reduce stress. However, few study authors have examined the effects of mindfulness-based interventions on adverse pregnancy outcomes that heighten cardiovascular risk.

OBJECTIVE

The aim of this study was to appraise available literature examining the effects of mindfulness-based interventions delivered during pregnancy on adverse pregnancy outcomes associated with future cardiovascular and cardiometabolic disease risk.

METHODS

In this systematic review, multiple electronic databases were searched using major keywords, including "mindfulness-based intervention," "pregnancy," "preterm delivery," "gestational diabetes," "small for gestational age," "preeclampsia," and "hypertension in pregnancy" during February 2023.

RESULTS

Six studies using mindfulness-based interventions during pregnancy were included. The review indicated that these interventions were largely effective at reducing prenatal stress; however, the overall effects of interventions were mixed concerning their impact on pregnancy complications. Study authors examining the effects on gestational diabetes-related outcomes reported significant improvements in blood glucose levels, hemoglobin A 1c , and oral glucose tolerance. Outcomes were mixed or inconclusive related to the effects of interventions on the incidence of preterm birth, birth of a small-for-gestational-age newborn, and preeclampsia.

CONCLUSIONS

Mitigating cardiovascular and cardiometabolic risk-associated adverse pregnancy outcomes through mindfulness-based approaches may represent an emerging field of study. The few studies and limited, mixed findings synthesized in this review indicate that high-validity studies are warranted to examine the effects of mindfulness-based interventions on pregnancy complications that contribute to cardiovascular-related maternal morbidity and suboptimal life course health for diverse birthing persons.

Exploring associations between pregnancy cravings and sociodemographic, lifestyle and health factors: insights from a cross-sectional population study in Jordan

OBJECTIVE

To explore the potential associations between pregnancy cravings and various sociodemographic, lifestyle and health factors.

DESIGN

Cross-sectional study.

SETTING

Population-based study in Jordan.

PARTICIPANTS

A total of 500 women who had children and experienced pregnancy cravings were included.

PRIMARY AND SECONDARY OUTCOME MEASURES

Pregnancy cravings are prevalent among Jordanian women and associated with some sociodemographic, lifestyle and health factors.

RESULTS

The results showed that 75.40% (377/500) of women experienced food cravings, with 40.6% and 29.1% of them having iron deficiency and vitamin D deficiency, respectively. The most commonly craved food items were sweets (17.2%, 86/500) and salts (22.2%, 115/500), while less than 1.0% of women craved non-food items. No significant correlation (p>0.05) was found between food cravings and the gender of the babies. Significant associations were found between food cravings and the mother's educational level (p=0.023), weight loss (p<0.001) and diseases such as anaemia (p=0.01).

CONCLUSION

Pregnancy cravings, particularly for food items, with sweets and salts being the most commonly craved, are prevalent among Jordanian women and are associated with the mother's educational level, changes in weight and the presence of anaemia. Additionally, the study found that iron and vitamin D deficiencies are prevalent health issues among women experiencing these cravings in Jordan. This research has important implications, emphasising the pressing need for targeted nutritional interventions and healthcare strategies to address identified deficiencies and improve maternal health outcomes in the region.

The COVID-19 Pandemic and Psychopathological symptoms in pregnant women in Spain

BACKGROUND

During the COVID-19 pandemic, pregnant women are exposed to potentially harmful stressors that might affect their health. The direct consequences that SARS-CoV-2 may have on perinatal mental health are still unknown.

OBJECTIVE

The present study aimed to explore the impact of the COVID-19 pandemic on psychopathological symptoms in a sample of Spanish pregnant women.

METHODS

A sample of 186 pregnant women was assessed using the revised Symptoms Check List-90 during the first lockdown in Spain.

RESULTS

The results showed clinical scores on the obsession and compulsion, anxiety and phobic anxiety subscales, as well as on the severity indexes. Phobic anxiety was the only variable that was inversely correlated with age and the number of previous miscarriages. A linear regression model showed that age was inversely associated with phobic anxiety scores. A younger age was associated with higher levels of phobic anxiety symptoms.

CONCLUSIONS

Our results indicated that younger pregnant women and women in the first trimester of pregnancy were more vulnerable to the effects of stress and concerns about COVID-19.

Contributions of CenteringPregnancy to women's health behaviours, health literacy, and health care use in the Netherlands

The objective of this study was to assess the effects of CenteringPregnancy (CP) in the Netherlands on different health outcomes. A stepped wedged cluster randomized trial was used, including 2132 women of approximately 12 weeks of gestation, from thirteen primary care midwifery centres in and around Leiden, Netherlands. Data collection was done through self-administered questionnaires. Multilevel intention-to-treat analysis and propensity score matching for the entire group and separately for nulliparous- and multiparous women were employed. The main outcomes were: health behaviour, health literacy, psychological outcomes, health care use, and satisfaction with care. Women's participation in CP is associated with lower alcohol consumption after birth (OR = 0.59, 95 %CI 0.42-0.84), greater consistency with norms for healthy eating and physical activity (β = 0.19, 95 %CI 0.02-0.37), and higher knowledge about pregnancy (β = 0.05, 95 %CI 0.01-0.08). Compared to the control group, nulliparous women who participating in CP reported better compliance to the norm for healthy eating and physical activity (β = 0.28, 95 %CI0.06-0.51)) and multiparous CP participants consumed less alcohol after giving birth (OR = 0.42, 95 %CI 0.23-0.78). Health care use and satisfaction rates were significantly higher among CP participants. A non-significant trend toward lower smoking rates was documented among CP participants. Overall, the results of this study reveal a positive (postpartum) impact on fostering healthy behaviours among participants.

Prenatal Maternal Stress and Pediatric Asthma Across Development: Adolescent Female-Specific Vulnerability

Prenatal maternal stress (PNMS) is linked to physical sequelae in offspring, including childhood asthma. This study sought to examine the roles of objective and subjective PNMS in the development of asthma at offspring ages 5 and 15. The sample included 815 mother-child dyads from the Mater Misericordiae Mothers' Hospital-University of Queensland Study of Pregnancy. PNMS was measured via retrospective self-report during pregnancy and 3-5 days after birth. Postnatal maternal stress was measured at offspring age 5. Objective PNMS was associated with elevated asthma risk at age 5 (OR 1.21, 95% CI 1.00, 1.45, p = 0.05), albeit not above concurrent postnatal stress. Sex moderated the association between PNMS and asthma at age 15, controlling for postnatal stress. Sex stratified analyses revealed a positive association between objective PNMS and age 15 asthma in females, but not males. Results provide evidence that PNMS may impact asthma outcomes in adolescence.

Measuring Fear of Childbirth Among a Diverse Population in the United States: A Revised Wijma Delivery Expectancy/Experience Scale (WDEQ-10)

INTRODUCTION

The current gold standard instrument used to measure fear of childbirth is the Wijma Delivery Expectancy/Experience Questionnaire (WDEQ). However, the existing scale is long, has translational challenges, and lacks data specific to experiences of a diverse population in the United States, making it challenging to assess how fear of childbirth impacts perinatal health care disparities. The objective of this study was to revise the WDEQ and analyze its reliability and validity for use in the United States.

METHODS

The questionnaire was revised using qualitative data from a previously published study of fear of childbirth within a racially, ethnically, and economically diverse group of pregnant or postpartum people in the United States. Psychometric properties were analyzed in terms of construct validity, reliability, and factor analysis from a group of 329 participants.

RESULTS

The revised and shortened 10 item WDEQ-10 comprises 3 subscales: fear of environmental factors, fear of death or injury, and fear of how they feel. The results indicate that the WDEQ-10 demonstrates good reliability and validity and confirmed the multidimensionality of fear of childbirth through a 3-factor solution.

DISCUSSION

The WDEQ-10 is a readable and accessible instrument that will allow health care providers and researchers to accurately measure complex components of how pregnant people experience fear of childbirth.

Psychosocial Risk Factors and Psychopathological Outcomes: Preliminary Findings in Italian Pregnant Women

The perinatal period may represent a particularly challenging time for expecting parents. Previous studies have highlighted an association between several perinatal risk conditions (e.g., childhood maltreatment, poor social support, and stress levels) and the development of psychopathological symptoms in pregnant women, especially depression symptoms. The current study examined the effects of psychosocial risk factors (childhood maltreatment, poor social support, and stressful events) on anxiety, depression, perceived stress, irritability/anger, relationship problems, psychosomatic symptoms, specific physiological problems, and addiction/at-risk behaviors. Sixty-one pregnant women (age range = 24–45) participating in a larger study completed questionnaires about childhood maltreatment (CECA Q.), Maternity Social Support Scale (MSSS), questionnaire on stressful events, and the Perinatal Assessment of Maternal Affectivity (PAMA) during their pregnancy. Results from regression analysis indicated that the presence of childhood maltreatment predicted elevated depressive symptoms, elevated irritability and anger, and elevated relationship problems. Further, stressful events in the year prior to pregnancy predicted elevated psychosomatic symptoms during pregnancy. No other significant associations were found. In this study, traumatic childhood events were strongly associated with mental health symptoms during pregnancy. This is an important finding that suggests the importance of screening and targeting psychotherapeutic interventions for vulnerable women during pregnancy.

Measuring stress after childbirth: development and validation of the Maternal Postpartum Stress Scale

BACKGROUND

Due to a wide range of stressors during the first postpartum year, this study aimed to develop and validate a self-report measure of stress intensity specific for postpartum.

METHOD

Postpartum women (N= 603) completed the Maternal Postpartum Stress Scale in a cross-sectional online study. They also filled out questionnaires on general stress, depression, and anxiety . Factor analysis, reliability, and validity were examined.

RESULTS

Exploratory factor analyses revealed a three-factor structure: Personal needs and fatigue , Infant nurturing , and Body changes and sexuality. The reliability of the total scale and all subscales was good. Significant positive correlation with general stress indicated good convergent validity, and with depression and anxiety good divergent validity. Primiparous mothers had a higher score on the Infant nurturing subscale, and the mothers of infants with health problems had a higher score on the total scale, Personal needs and fatigue, and Infant nurturing.

CONCLUSION

Maternal Postpartum Stress Scale is a new, valid, and reliable 22-items scale that measures stress during the first postpartum year. The total scale and tree subscales can be calculated separately to provide detailed information about stressors that mothers struggle with. The scale can be used for research and practical purposes.

What is prenatal stress? A scoping review of how prenatal stress is defined and measured within the context of food insecurity, housing instability, and immigration in the United States

BACKGROUND

Stress during pregnancy can lead to significant adverse outcomes for maternal mental health. Early evaluation of prenatal stress can help identify treatment needs and appropriate interventions. Disparities in the social determinants of health can contribute to stress, but what constitutes stress during pregnancy within the social determinants of health framework is poorly understood.

OBJECTIVE

To scope how prenatal stress is defined and measured among pregnant people exposed to three prominent social stressors in the United States: insecurity pertaining to food, housing, and immigration.

ELIGIBILITY CRITERIA

We included all studies that focused on stress during pregnancy in the context of food insecurity, housing instability, and immigration, given their recent policy focus due to the COVID-19 pandemic and ongoing political discourse, in addition to their importance in American College of Obstetricians and Gynecologists (ACOG's) social determinants of health screening tool.

SOURCES OF EVIDENCE

We searched PubMed, Scopus, and Web of Science for articles published between January 2012 and January 2022.

CHARTING METHODS

Using a piloted charting tool, we extracted relevant study information from the selected articles and analyzed the content pertaining to stress.

RESULTS

An initial search identified 1,023 articles, of which 24 met our inclusion criteria. None of the studies defined prenatal stress, and only one used the Prenatal Distress Questionnaire, a prenatal stress-specific tool to measure it. The Perceived Stress Scale was the most common instrument used in seven studies. Fifteen studies measured over 25 alternative exposures that researchers theorized were associated with stress, and 4 of the 15 studies did not explain the association between the measure and stress.

CONCLUSIONS

Our findings demonstrate a fundamental inconsistency in how prenatal stress is defined and measured in the context of social determinants of health, limiting the comparison of results across studies and the potential development of effective interventions to promote better maternal mental health.

Hair Cortisol Concentration as a Biomarker of Symptoms of Depression in the Perinatal Period

Pregnancy is a sensitive period when women experience major hormonal and psychological changes. A high prevalence of the symptoms of depression and manifested major depression rates have been reported during this period, leading to negative outcomes both for mothers and the offspring. Despite its prevalence, the aetiology of depression is not yet fully understood. Nonetheless, alterations in cortisol levels have been proposed as a reliable biomarker to identify pregnant women at risk of perinatal depression. Hair cortisol has recently been extensively used in bio-psychological studies as a suitable non-invasive biomarker for several neuropsychiatric disorders. Various studies have published evidence regarding the relationship between cortisol fluctuations during the perinatal period, measured both in hair and in other substrates, and the onset of perinatal symptoms of depression. This current review provides an overview of cortisol level changes measured in women's hair during pregnancy or the postpartum period and its association with perinatal symptoms of depression. Further studies, including repetitive measurement of both hair cortisol and depression throughout the prenatal period, must be performed to clarify the relationship between cortisol levels and perinatal symptoms of depression.

A new scale for fear of childbirth: the Fear of Childbirth Questionnaire (FCQ)

OBJECTIVE

To create a clear and acceptable measure of fear of childbirth with satisfactory content validity for use with English-speaking women in the UK.

BACKGROUND

Fear of childbirth (FOC) can have a significant impact on a woman's view of her pregnancy, birth and her recovery post birth. Early identification is paramount to ensure that women's needs are recognised so that appropriately tailored care can be provided in pregnancy. Availability of reliable and valid measures to assess FOC in an English-speaking population are sparse, mainly due to issues with definitions of FOC or cultural sensitivity after translation. Recent research from phase one of the Fear of Childbirth study (FOCUS), has established key elements for FOC in an English-speaking UK population, and allows for a culturally sensitive measure of FOC to be developed. The aim was to ensure inclusion of all ten FOC elements and to attend to guidance from women in phase two of the FOCUS study about what would ensure clarity and acceptability.

METHOD

A multidisciplinary team developed items in accordance with FOCUS. The measure was then piloted with one reviewer and further refined by the team of perinatal researchers.

RESULTS

The FCQ is a new 20-item fear of childbirth questionnaire, which has been developed and is grounded in fears reported by women in the UK.

CONCLUSION

A new tool to measure FOC in an English-speaking UK population with good content validity has undergone a preliminary phase of development and now needs testing for reliability and other forms of validity.

Common model of stress, anxiety, and depressive symptoms in pregnant women from seven high-income Western countries at the COVID-19 pandemic onset

OBJECTIVE

Increases in stress, anxiety, and depression among women pregnant during the COVID-19 pandemic have been reported internationally. Yet rigorous comparison of the prevalence of maternal mental health problems across countries is lacking. Moreover, whether stress is a common predictor of maternal mental health during the pandemic across countries is unknown.

METHODS

8148 pregnant women from Germany, Israel, Italy, Poland, Spain, Switzerland, and the United States were enrolled in the International COVID-19 Pregnancy Experiences (I-COPE) Study between April 17 and May 31, 2020. Sociodemographic characteristics, pandemic-related stress, pregnancy-specific stress, anxiety, and depression were assessed with well-validated instruments. The magnitude of stress and mood disturbances was compared across countries. A path model predicting clinically significant levels of anxiety and depression from maternal characteristics and stress was tested for all study participants and then examined separately in each country with >200 participants.

RESULTS

Countries differed significantly in magnitude of pandemic-related pregnancy stress and pandemic-unrelated pregnancy-specific stress, and in prevalence of clinically significant anxiety and depression levels. A well-fitting common path model for the entire sample indicated that mood and anxiety disturbances were strongly predicted by pandemic-related and pregnancy-specific stress after accounting for maternal characteristics. The model was replicated in individual countries.

CONCLUSIONS

Although pregnant women in high-income Western countries experienced different levels of stress resulting from the COVID-19 pandemic, stress is a strong, common predictor of anxiety and depressive symptoms in these individuals. The common model can be used to inform research and clinical interventions to protect against adverse consequences of prenatal maternal stress, anxiety, and depression for mothers and infants.

Cultural adaptation and psychometric validation of the Pregnancy Experience Scale–Brief version (PES-Brief) in Pakistani women with antenatal anxiety symptoms

Background

Pregnancy experiences influence fetal and birth outcomes. There is scarcity of locally validated tools to assess pregnancy experiences. We aimed to validate the Pregnancy Experience Scale-Brief (PES-Brief) in pregnant Pakistani women with anxiety symptoms.

Methods

A two-step process was used including 1) adaptation via translation/back-translation followed by cognitive interviewing with 10 participants and 2) factor analysis and validation with 605 women in Rawalpindi Pakistan who had mild-moderate symptoms of anxiety, attended the antenatal clinic, and were ≤22 weeks of gestation and ≥18 years old. We calculated internal consistency and reliability and conducted exploratory and confirmatory factor analyses.

Results

Cultural adaptation led to inclusion of one item of the hassles subscale and exclusion of one item in the uplifts subscale, resulting in 9 uplifts and 11 hassles. Exploratory factor analysis supported a two-factor structure, with the adapted items exhibiting loading values of ≥0.24 for their respective factors. Internal consistency was demonstrated for uplifts (Cronbach's alpha = 0.89) and hassles (Cronbach's alpha = 0.85) subscales. Uplift intensity was moderately correlated with the Hospital Anxiety and Depression Scale anxiety subscale (r = 0.54, 95% CI:0.30-0.77).

Conclusion

The Urdu PES-Brief is a reliable and valid tool for use in Pakistani pregnant women with antenatal anxiety. Future studies on its validity are needed on women without symptoms anxiety.

A psycho-educational intervention programme for parents with SGA foetuses supported by an adaptive mHealth system: design, proof of concept and usability assessment

Background

Technology-based approaches during pregnancy can facilitate the self-reporting of emotional health issues and improve well-being. There is evidence to suggest that stress during pregnancy can affect the foetus and result in restricted growth and preterm birth. Although a number of mobile health (mHealth) approaches are designed to monitor pregnancy and provide information about a specific aspect, no proposal specifically addresses the interventions in parents at risk of having small-for-gestational-age (SGA) or premature babies. Very few studies, however, follow any design and usability guidelines which aim to ensure end-user satisfaction when using these systems.

Results

We have developed an interactive, adaptable mHealth system to support a psycho-educational intervention programme for parents with SGA foetuses. The relevant results include a metamodel to support the task of modelling current or new intervention programmes, an mHealth system model with runtime adaptation to changes in the programme, the design of a usable app (called VivEmbarazo) and an architectural design and prototype implementation. The developed mHealth system has also enabled us to conduct a proof of concept based on the use of the mHealth systems and this includes data analysis and assesses usability and acceptance.

Conclusions

The proof of concept confirms that parents are satisfied and that they are enthusiastic about the mHealth-supported intervention programme. It helps to technically validate the results obtained in the other stages relating to the development of the solution. The data analysis resulting from the proof of concept confirms that the stress experienced by parents who followed the mHealth-supported intervention programme was significantly lower than among those who did not follow it. This implies an improvement in the emotional health not only of the parents but also of their child. In fact, the babies of couples who followed the mHealth-supported programme weigh more than the babies of couples under traditional care. In terms of user acceptance and usability, the analysis confirms that mothers place greater value on the app design, usefulness and ease of use and are generally more satisfied than their partners. Although these results are promising in comparison with more traditional and other more recent technology-based approaches.

Associations between childhood maltreatment, poor sleep, and prenatal distress in pregnant adolescents

Childhood maltreatment (CM) is a known risk factor for adolescent pregnancy. Sleep disturbances and psychological distress, both common negative sequelae of CM, often co-occur during pregnancy, although directionality remains unclear. Furthermore, little is known about how CM affects sleep-distress associations during pregnancy. In pregnant adolescents, we examined: (a) whether there are significant predictive associations from CM to sleep quality and distress and (b) bidirectional influences of distress and sleep quality. Healthy pregnant adolescents (n = 204) were recruited before or during the 2nd trimester. CM was assessed at enrollment; sleep quality and distress were assessed in the 2nd and 3rd trimesters. Hypotheses were tested using path analysis. Findings revealed that CM was associated with worse 2nd trimester sleep quality and distress (β = .19, p < .05 for sleep; β = .30, p < .001 for distress). Higher levels of 2nd trimester distress were associated with lower 3rd trimester sleep quality (β = .19, p < .05). Findings provide novel information about (a) associations from CM to prenatal mood and sleep in pregnant adolescents, and (b) sleep-distress directionality over the course of pregnancy. These results have implications for better understanding the ways in which CM potentially exerts influences later in life, and for targeting interventions to address physical and mental health during pregnancy.

Intolerance of Uncertainty and Perfectionistic Beliefs About Parenting as Cognitive Mechanisms of Symptom Change During Cognitive Behavior Therapy for Perinatal Anxiety

OBJECTIVE

A recent randomized controlled trial of group cognitive behavior therapy (CBGT) for perinatal anxiety showed that CBGT is effective in reducing anxiety and depression in pregnant and postpartum women. In secondary analyses, the role of potential mechanisms of symptom change was examined, including intolerance of uncertainty (IU), self-oriented parenting perfectionism (SOPP) and societal-prescribed parenting perfectionism (SPPP).

METHOD

The sample included 75 women (M_age = 31.99, SD = 3.57; 37.3% pregnant, 62.7% postpartum) who sought treatment for anxiety and completed the 6-week CBGT or 6-week waitlist within the larger trial. Measures of anxiety (State-Trait Inventory for Cognitive and Somatic Anxiety; STICSA), depression (Edinburgh Postnatal Depression Scale; EPDS), and the proposed mediators (IU, SOPP, SPPP) were completed at baseline and 6-weeks post-baseline.

RESULTS

Two moderated mediation models were evaluated to identify potential mediators of the effect of condition (CBGT, waitlist) on anxiety (STICSA; Model 1) or depressive symptoms (EPDS; Model 2). In Model 1, changes in IU partially mediated the effect of condition on anxiety (STICSA) for both pregnant and postpartum women. Changes in SOPP and SPPP were partial mediators for postpartum women only. Change in depression (EPDS) was also a partial mediator for pregnant women in this model. In Model 2, none of the cognitive variables mediated the effect of condition on depressive symptoms (EPDS). However, change in anxiety (STICSA) was a significant mediator of the effect of condition on depression (EPDS) and only among pregnant women.

CONCLUSIONS

The results provide support for IU, SOPP and SPPP as mechanisms of change during CBGT and identify differences in important mechanisms among pregnant and postpartum women.

Pregnancy anxiety, placental corticotropin-releasing hormone and length of gestation

OBJECTIVE

High pregnancy anxiety is a consistent predictor of earlier labor and delivery. Placental corticotropin-releasing hormone (pCRH) predicts earlier delivery consistently and it has been identified as a biological mediator of the association between pregnancy anxiety and gestational length. However, studies have not examined whether changes in pregnancy anxiety are associated with earlier birth as mediated by changes in pCRH during pregnancy. Accordingly, this study tests whether linear changes in pregnancy anxiety are associated with length of gestation indirectly through nonlinear increases in pCRH over pregnancy.

METHODS

A sample of pregnant women (n=233) completed prenatal assessments in early pregnancy, second trimester, and third trimester that included a 4-item assessment of pregnancy anxiety and collection of blood samples assayed for pCRH using radioimmunoassay. Length of gestation was abstracted from medical records after birth.

RESULTS

Increases in pregnancy anxiety from early pregnancy to third trimester predicted shorted length of gestation, as did nonlinear increases in pCRH over pregnancy. However, there was no evidence of an indirect effect of changes in pregnancy anxiety on length of gestation via changes in pCRH.

CONCLUSIONS

These results indicate that linear changes in pregnancy anxiety and nonlinear changes in pCRH during pregnancy are independent risk factors for shortened gestational length. This study adds to a small but growing body of work on biopsychological processes in pregnancy and length of gestation. Modeling changes in psychological and biological processes during pregnancy could provide more insight into understanding risk for adverse pregnancy outcomes.

Effects of single and combined exposure to lead and stress during pregnancy on offspring neurodevelopment

Objective

To assess associations of single and combined exposures to lead and stress during different stages of pregnancy with offspring neurodevelopment.

Methods

We measured prenatal lead (maternal blood-lead in early-pregnancy and umbilical-cord-blood-lead) and maternal stress levels in Shanghai-Birth-Cohort from 2013 to 2016. Maternal stress was assessed using Center-for-Epidemiological-Studies-Depression-Scale and Self-Rating-Anxiety-Scale during mid-pregnancy. The Ages-Stages-Questionnaires-3 (at 6/12-months-of-age) and Bayley-III (at 24-months-of-age) were both used to assess neurodevelopment.

Results

A total of 2132 mother-child pairs with both prenatal lead and stress measurements were included. The geometric-means of blood-lead in early-pregnancy and cord-blood-lead were 1.46 μg/dL and 1.33 μg/dL, respectively. Among the study women, 1.89 % and 0.14 % were screened positive for depression and anxiety. Adjusting for related confounders, the combined exposures had stronger adverse associations with offspring social-emotional skills than single exposures; and the combined exposure in early-pregnancy was associated with greater neurodevelopmental differences than combined exposure around-birth, especially in social-emotion at 24 months-of-age [β (95 %CI): − 10.48(−17.42, −3.54) vs. − 5.95(−11.53, −0.36)].

Conclusions

Both single and combined prenatal exposures to lead/stress impaired infant neuro-development, and the effects of combined exposure may be more profound than single exposures. Combined exposure in early-pregnancy may be associated with worse neurodevelopmental outcomes than combined exposure around-birth, especially in social-emotional development.

•

Effects of prenatal single and combined exposure to lead and stress were investigated using a large-scale birth cohort.

•

The overall levels of prenatal exposures to lead/stress were relatively low in the Shanghai study women.

•

Adverse effects of prenatal combined exposure on offspring neurodevelopment may be more profound than single exposure.

•

The impaired neurodevelopment domains in the offspring mainly include social-emotional development.

•

Higher levels of impairments were induced when the combined exposure occurred in an earlier stage of pregnancy.

Resilience, stress and anxiety in pregnancy before and throughout the pandemic: a structural equation modelling approach

The present study explored and compared the link between resilience and pregnancy-related stress, perceived stress, and anxiety, employing two structural equation models. One model focused on pregnant women before the outbreak of the pandemic, and the other on pregnancies throughout the pandemic. For this purpose, a total sample of 690 women during their pregnancy were collected: the Pre-Pandemic Group (P-PG) was composed of 341 pregnant women evaluated prior to the pandemic; and 349 pregnant women assessed at the time of the pandemic constituted the Pandemic Group (PG). The resilience, pregnancy-related stress, perceived stress, and anxiety symptomatology of the women were assessed. For both samples, resilience was found to lower levels of pregnancy-specific stress, as well as general perceived stress, and anxiety symptomatology. Furthermore, pregnancy-specific stress and perceived stress showed a covariance relationship and, that these, in turn, increased the anxiety. Moreover, the PG showed greater levels of pregnancy-specific stress, anxiety, somatisations, and obsessions-compulsions, while the P-PG presented higher perceived stress levels.

The impact of the coronavirus pandemic curfew on the psychosocial lives of pregnant women in Jordan

OBJECTIVES

Worldwide the COVID-19 pandemic has negatively affected the health and psychosocial lives of people. International guidelines recommend special attention to pregnant women during pandemics and national emergencies. This study aimed to report the impact of the COVID-19 pandemic curfew on the psychosocial lives of pregnant women in Jordan.

DESIGN

A cross-sectional study was conducted and included women who were pregnant during the COVID-19 curfew in Jordan, which took place between mid-March and mid-June of 2020.

SETTINGS

A web-based survey that was posted on various social media platforms.

PARTICIPANTS

Women who at the time of the study were 18 years of age or more, were living in Jordan, and were pregnant during the curfew.

MEASUREMENTS AND FINDINGS

Data collected included women's characteristics, the impact of the curfew on the pregnancy, physical activity, and psychosocial lives and the barriers to seeking healthcare, in addition to pregnancy and delivery details, and changes in nutrition and supplements intake. A total of 877 women responded to the survey. The results showed that 21.1% of the respondents did not receive any antenatal care (ANC) during the curfew. The respondents also reported that the main barriers for seeking ANC included healthcare facilities being closed (85.2%), the need for travel permits (76.8%), financial difficulties (63.9%), and fear of catching the COVID-19 virus (60.1%). Furthermore, 93.3% reported that they had psychological stress, and 29.9% reported that they had at least one form of domestic violence. Statistically significant associations existed between various women's characteristics, obstetric, psychosocial factors, and the level of psychological stress.

KEY CONCLUSIONS

The COVID-19 pandemic curfew, which was applied in Jordan, resulted in a negative impact on the psychosocial lives of pregnant women. As a result, pregnant women did not receive optimal antenatal care and experienced higher degrees of psychological stress and domestic violence.

IMPLICATIONS FOR PRACTICE

The findings of our study may encourage national healthcare policymakers to ensure the provision of appropriate psychosocial support of pregnant women during large scale emergencies.

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

BACKGROUND

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

METHODS

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

RESULTS

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

DISCUSSION

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

Factors associated with prenatal stress and anxiety in pregnant women during COVID-19 in Spain

AIM OF THE STUDY

To describe prenatal stress and state anxiety levels in pregnant women living in Spain during the lockdown of the first wave of COVID-19 and its relation with obstetric factors, perception of health care, and concerns about the socio-sanitary situation.

METHODS

The present study is an observational, correlational, and cross-sectional quantitative study. The participants in the study were pregnant women recruited through non-probabilistic convenience and snowball sampling during the lockdown. A web link was provided to an online questionnaire designed for this research, which collected socio-demographic and obstetric variables, perceptions of health care received during the pandemic and preoccupations associated with COVID-19. It also included the Prenatal Stress Questionnaire (PDQ) and the State Anxiety Inventory (STAI-S).

RESULTS

Based on the responses of 695 pregnant women, the results showed a mean of 16.98 (SD = 25.20) of prenatal stress and elevated levels of anxiety (M = 25.20/SD = 11.07) in the first wave of the pandemic. Risk factors for prenatal stress and anxiety were the level of preoccupation associated with COVID-19 and previous mental health issues. A specific risk factor for anxiety was having more than one child and a protective factor were perceiving accessibility and availability of health care, with clear and consistent pregnancy care and follow-up protocols.

CONCLUSIONS

The lockdown period for COVID-19 was a stressful experience for pregnant women, highlighting the need to address their psychological well-being through clear and coherent protocols in terms of maternal-foetal health control and follow-up.

Aim of the study

To describe prenatal stress and state anxiety levels in pregnant women living in Spain during the lockdown of the first wave of COVID-19 and its relation with obstetric factors, perception of health care, and concerns about the socio-sanitary situation.

Methods

The present study is an observational, correlational, and cross-sectional quantitative study. The participants in the study were pregnant women recruited through non-probabilistic convenience and snowball sampling during the lockdown. A web link was provided to an online questionnaire designed for this research, which collected socio-demographic and obstetric variables, perceptions of health care received during the pandemic and preoccupations associated with COVID-19. It also included the Prenatal Stress Questionnaire (PDQ) and the State Anxiety Inventory (STAI-S).

Results

Based on the responses of 695 pregnant women, the results showed a mean of 16.98 (SD = 25.20) of prenatal stress and elevated levels of anxiety (M = 25.20/SD = 11.07) in the first wave of the pandemic. Risk factors for prenatal stress and anxiety were the level of preoccupation associated with COVID-19 and previous mental health issues. A specific risk factor for anxiety was having more than one child and a protective factor were perceiving accessibility and availability of health care, with clear and consistent pregnancy care and follow-up protocols.

Conclusions

The lockdown period for COVID-19 was a stressful experience for pregnant women, highlighting the need to address their psychological well-being through clear and coherent protocols in terms of maternal-foetal health control and follow-up.

Life stressors, hypertensive disorders of pregnancy, and preterm birth

BACKGROUND

Stress-induced pregnancy complications are thought to represent a significant cause of maternal morbidity and mortality; little is known regarding types of stress most predictive of adverse outcomes.

METHODS

We used Utah PRAMs 2012-2014 data to evaluate links between preconception life stressors and prevalence of hypertensive disorders of pregnancy (HDP) and pre-term labor (PTB) (births <37 weeks gestational age, and very PTB <33 weeks). We categorized 12 specific stressful events into 4 groups: partner, traumatic, financial, and emotional. Adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) were estimated controlling for important sociodemographic, lifestyle, and pregnancy history factors.

RESULTS

4,378 mothers completed the survey. 26.6%, 12.2%, 32.2%, and 28.4% reported partner, traumatic, financial, and emotional-related stress. Reporting any of the 4-types of life stress was linked with increased prevalence of HDP (aPR: 1.46 [95% CI: 0.96, 2.22]) after adjusting for age, race/ethnicity, BMI, education, prior diagnosis of high blood pressure, and prior history of preterm labor. The strongest association was observed for financial stress (aPR: 1.50 [95% CI: 1.03, 2.18]). Financial stress was also associated with increased prevalence of very PTB (aPR: 1.61 [95% CI: 1.03, 2.51]) after adjustment.

CONCLUSION

Women reporting financial stress, including job loss, pay reduction, or difficulty paying bills, had increased prevalence of HDP and very PTB.

Validity and reliability of the Greek version of Pregnancy Outcome Questionnaire (POQ)

BACKGROUND

During the last decades a considerable increase in biological and psychosocial approaches have occurred so as to enhance the study of prenatal period. This study aimed to investigate the validity and reliability of the Greek version of Pregnancy Outcome Questionnaire (POQ) in assessing pregnancy-related stress.

MATERIAL AND METHODS

The study group consisted of 135 first-time expectant women with good knowledge of the Greek language, low-risk pregnancies and a gestational age of ≥24 weeks. Questionnaires containing the POQ scale questions in addition to other questions and scaleswere distributed in printed and digital format at private gynecological clinics. The collected data were analysed using the SPSS software.

RESULTS

The POQ scale score showed satisfactory reliability (Cronbach's alpha = 0.8), while the factor analysis showed a major factor with an eigenvalue of 4.17 and an overall interpreted factor variance of 41%. The sample showed moderate intensity values on the scale. We observed that pregnancy-related characteristics affected the scale, while no significant correlations with demographic variables were recorded.

CONCLUSION

The results of the reliability and factor analyses evaluating the scale structure indicated that the tool performed well in Greek, had a compact structure with satisfying reliability, and is suitable for use in the Greek pregnant population. However, additional research is warranted to investigate the effect of various additional factors on the scale.

Cortisol levels versus self-report stress measures during pregnancy as predictors of adverse infant outcomes: a systematic review

Systematically review existing evidence to (1) identify the association between self-report stress and cortisol levels measured during pregnancy; and, (2) assess their association with adverse infant outcomes to determine which is the better predictor. A systematic review was conducted in accordance with PRISMA guidelines. Search terms focused on pregnancy, psychological stress and cortisol. Nine electronic databases were searched, in addition to reference lists of relevant papers. Eligibility criteria consisted of studies that included measurement of self-reported psychological stress, cortisol and assessed their associations with any infant-related outcome. Further limits included studies published in English or Spanish with human female participants. A meta-regression was not feasible due to differences in study samples, measurement tools employed, types of cortisol assessed and outcomes reported. A narrative synthesis was provided. 28 studies were eligible for inclusion. Convergent validity between self-report measures and cortisol was reported by three studies (range r = 0.12-0.41). Higher levels of self-report stress were significantly associated with intrauterine growth restriction (fetal biparietal diameter, low fetal head circumference, abdominal circumference), low gestational age at birth, low anthropometric measures (birth length, head circumference, length of the neonate), poor infant neurodevelopment (cognitive development) and potentially pathogenic gut microbiota (Clostridiaceae Clostridium, Haemophilus) in six studies. Higher cortisol levels were significantly associated with intrauterine growth restriction (fetal biparietal diameter, low fetal head circumference, abdominal circumference), low gestational age at birth, low infant birth weight, poor infant neurodevelopment (attention scores on the Network Neurobehavioral Scale) and low levels of potentially protective gut microbiota (Lactobacillus, Slackia and Actinobaculum) in 13 studies. Of the studies that assessed which type of measure was a better predictor of infant outcomes (n = 6), there was agreement that cortisol levels were statistically better at predicting adverse outcomes than self-reported stress. Self-report stress measures appear to be modest predictors of adverse infant outcomes in comparison to cortisol. A number of methodological limitations need to be addressed in future studies to help understand the relationship between cortisol and self-reported stress and how they are related to adverse infant outcomes.

The relationship of trait mindfulness to physical and psychological health during pregnancy

INTRODUCTION

Research on mindfulness has extended to the prevention of psychopathology and physical conditions during pregnancy. The purpose of this study was to investigate the relationship between trait mindfulness assessed in the first or early second trimester to health outcomes throughout pregnancy.

METHODS

A total of 510 women were recruited at McGill University-affiliated obstetrics clinics (average gestational age: 13.43 weeks, sd = 1.2). The Mindful Awareness and Attention Scale (MAAS) was administered at baseline. At three timepoints during pregnancy, participants completed the Perceived Stress Scale (PSS-10), the Edinburgh Postnatal Depression Scale (EPDS), the Prenatal Distress Questionnaire-revised (PDQR) and a measure of pregnancy symptom intensity and indicated whether they had been diagnosed with gestational diabetes or high blood pressure.

RESULTS

Higher MAAS scores predicted lower PSS, EPDS and PDQR scores and less severe physical discomforts throughout pregnancy. MAAS scores were a stronger predictor of PSS scores earlier in pregnancy. Logistic regressions found that trait mindfulness did not predict the presence of physical discomforts, diabetes or high blood pressure.

CONCLUSIONS

These results indicate that trait mindfulness is an important predictor of subjective stress, depression, anxiety and the severity of physical discomforts during pregnancy. These findings suggest that interventions earlier in pregnancy may increase the impact of mindfulness on maternal health.

Variation in Restrictive Abortion Policies and Adverse Birth Outcomes in the United States from 2005 to 2015

BACKGROUND

Since 2011, U.S. states have enacted more than 400 policies restricting abortion access. As structural determinants, abortion policies have the potential to influence maternal and child health access, outcomes, and equity through multiple mechanisms. Limited research has examined their implications for birth outcomes.

METHODS

We created a state-level abortion restrictiveness index composed of 18 restrictive abortion policies and evaluated the association between this index and individual-level probabilities of preterm birth (PTB) and low birthweight (LBW) within the United States and by Census Region, using data from the 2005-2015 National Center for Health Statistics Period Linked Live Birth-Infant Death Files. We used logistic multivariable regression modeling, adjusting for individual- and state-level factors and state and year fixed effects.

RESULTS

Among 2,500,000 live births, 269,253 (12.0%) were PTBs and 182,960 (8.1%) were LBW. On average from 2005 to 2015, states had approximately seven restrictive abortion policies enacted, with more policies enacted in the Midwest and South. Nationally, relationships between state restrictiveness indices and adverse birth outcomes were insignificant. Regional analyses revealed that a 1-SD increase in a state's restrictiveness index was associated with a 2% increase in PTB in the Midwest (marginal effect [ME], 0.25; 95% confidence interval [CI], 0.04-0.45; p < .01), a 15% increase in LBW in the Northeast (ME, 1.24; 95% CI, 0.12-2.35; p < .05), and a 2% increase in LBW in the West (ME, 0.12; 95% CI, 0.01-0.25; p < .05).

CONCLUSION

Variation in restrictive abortion policy environments may have downstream implications for birth outcomes, and increases in abortion restrictions were associated with adverse birth outcomes in three out of four Census Regions.

Psychometric properties of the Italian version of the Pandemic-Related Pregnancy Stress Scale (PREPS) and its correlation with anxiety and depression

BACKGROUND

In the beginning of 2020, Italy was the first European country to face the COVID-19 outbreak. Restrictions imposed during the pandemic, social isolation, and the cancellation of medical appointments likely resulted in stress that may have affected pregnant women adversely.

AIMS

To determine the psychometric validity of the Italian version of the Pandemic-Related Pregnancy Stress Scale (PREPS) in assessing COVID-19-related stress in pregnant women and to examine correlations between PREPS scales and symptoms of anxiety and depression.

METHODS

232 pregnant women attending the Obstetric-Gynecologic Clinic of an Academic Hospital were assessed with the PREPS, the Revised Prenatal Distress Questionnaire (NuPDQ), the General Anxiety Disorder-7 (GAD-7), and the Patient Health Questionnaire-2 (PHQ-2). We analyzed the internal consistency and factor structure of the PREPS. Convergent validity was examined by comparison with the NuPDQ. PHQ-2 and GAD-7 were used to measure the association with depression and anxiety.

RESULTS

Acceptable-to-good internal consistency was found for the three PREPS scales: Preparedness Stress (PS, α=0.760), Prenatal Infection Stress (PIS, α=0.857), and Positive Appraisal (PA, α=0.747). Correlations of the NuPDQ with both PREPS stress scale scores (PS and PIS) were statistically significant, but on multiple regression analysis only the PS scale was correlated with the NuPDQ. Prenatal infection stress predicted GAD-7 score, while Preparedness stress predicted PHQ-2 score.

LIMITATIONS

The main limitations were the small sample size and the cross-sectional design of the study.

CONCLUSION

The Italian PREPS exhibited good psychometric properties and associations with clinical symptoms of anxiety and depression.

Resilience and Stress during Pregnancy: A Comprehensive Multidimensional Approach in Maternal and Perinatal Health

This narrative review addresses resilience and stress during pregnancy, which is part of a broader concept of maternal health. Pregnancy and postpartum are opportune periods for health promotion interventions, especially because the close contact of the women with health professionals. In this way, it can be considered a useful window of opportunity to identify women at higher risk for adverse outcomes. Integrated health is a concept that aims at providing comprehensive care related to the promotion of individuals' physical, mental, and social well-being. In this context, stress during pregnancy has been targeted as a remarkable condition to be addressed whether due to individual issues, social issues, or specific pregnancy issues, since it is directly and indirectly associated with pregnancy complications. Stress is associated with preterm birth, postpartum depression, anxiety, child neurodevelopment, and fetal distress. The way that an individual faces a stressful and adverse situation is called resilience; this reaction is individual, dynamic, and contextual, and it can affect maternal and fetal outcomes. Low resilience has been associated with poorer pregnancy outcomes. The social context of pregnancy can act as a protective or contributory (risk) factor, indicating that environments of high social vulnerability play a negative role in resilience and, consequently, in perceived stress. A given stressor can be enhanced or mitigated depending on the social context that was imposed, as well as it can be interpreted as different degrees of perceived stress and faced with a higher or lower degree of resilience. Understanding these complex mechanisms may be valuable for tackling this matter. Therefore, in the pregnancy-puerperal period, the analysis of the stress-resilience relationship is essential, especially in contexts of greater social vulnerability, and is a health-promoting factor for both the mother and baby.

Prenatal maternal stress and autistic-like behaviours in Chinese preschoolers

Exposure to prenatal maternal stress (PNMS) has been implicated as a risk factor for a range of psychiatric disorders in children. However, there have been a few studies showing inconsistent associations between PNMS and offspring autistic-like behaviours. We therefore aimed to examine whether trimester-specific PNMS exposure might be related to an increased risk of autistic-like behaviours among preschoolers. Using data from Longhua Children Cohort Study, mothers of 65,931 preschool children were asked to recall their level of PNMS in each of the three trimesters of pregnancy, while children's current autistic-like behaviours were assessed using the Autism Behaviour Checklist. A series of Cox regression models were fitted to assess the association between PNMS exposure and autistic-like behaviours. After adjusting for potential confounders, the Cox regression models showed that PNMS exposure, especially during the second pregnant trimester, was significantly and positively associated with the presence of children's autistic-like behaviours. The strength of these associations was enhanced with the increase of PNMS exposure level. Furthermore, based on different permutations of exposure versus no exposure in each trimester, the participants were divided into eight groups. A cross-over analysis confirmed the aforementioned finding that the second pregnant trimester might be the sensitive period for PNMS exposure increasing the risk of autistic-like behaviours. Our findings supported the hypothesis of an association between PNMS exposure and autistic-like behaviours among preschoolers. Preventive interventions should be trialled to examine whether minimizing maternal psychological stress during pregnancy, especially the second trimester, may reduce the risk of offspring autistic-like behaviours.

Risk factors for antenatal depression: A review

Depression is the most prevalent mental disorder in pregnancy, and yet it is less studied than postpartum depression despite the consequences it may have on both the pregnant woman and her offspring. Therefore, it would be important to know which risk factors may favour the appearance of antenatal depression in order to carry out appropriate prevention interventions. The aim of the present review was to identify the main risk factors of antenatal depression. We searched in databases PubMed and PsycINFO for articles published about the factors associated with antenatal depression from January 2010 through December 2020. The literature review identified three main groups of antenatal depression risk factors: sociodemographic, obstetric, and psychological. First, among the sociodemographic variables, the low level of studies and the economic income clearly stood out from the rest. Then, not having planned the pregnancy was the main obstetric variable, and finally, the main psychological risk factors were having a history of psychological disorders and/or depression as well as presenting anxiety, stress, and/or low social support during pregnancy. This review shows that the antenatal depression is affected by multiple factors. Most can be identified at the beginning of the pregnancy, and some are risk factors potentially modifiable through appropriate interventions, such as psychological factors. For this reason, it is important to carry out a good screening for depression during pregnancy and consequently, be able to prevent its appearance or treat it if necessary.

Prenatal Stress and Psychiatric Symptoms During Early Phases of the COVID-19 Pandemic in Italy

PURPOSE

In February 2020, Italy became the first European country to face the coronavirus disease 2019 (COVID-19) outbreak. The concerns of infection, financial worries, loss of freedom, and isolation during the ongoing pandemic can lead to negative psychological effects, including anxiety, depression, and obsessive-compulsive disorder. The main aim of our study was to evaluate the relationship between pandemic-related stress and pregnancy-specific stress and assess their role in the development of psychiatric symptoms. We predicted that pregnancy-specific stress would mediate an association of pandemic-related stress with psychiatric symptoms.

PATIENTS AND METHODS

A total of 258 pregnant women were assessed for general emotional symptoms with the General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-2 (PHQ-2), and an Obsessive-Compulsive Disorder screening (OCD). The Revised Prenatal Distress Questionnaire (NuPDQ) and the Pandemic-Related Pregnancy Stress Scale (PREPS) were administered as measures of pregnancy-specific stress (PSS and pandemic-related, respectively). Mediation effects by NuPDQ for PREPS stress scales on psychiatric outcomes were calculated, using regression series and correcting for general covariates.

RESULTS

Almost a third of the sample reported clinically relevant anxiety levels (32.6%), 11.2% were positive for OCD screening and less than 5% were positive for depression screening. The stress related to feeling unprepared for delivery and postpartum (PREPS-PS) predicted PHQ-2 score, both directly and indirectly via PSS, and it predicted GAD-7 score only indirectly. The stress related to fear of infection (PREPS-PIS) was directly associated to GAD-7 score and - through PSS - to PHQ-2 score and OCD.

CONCLUSION

The pandemic onset contributed to poor mental health, especially anxiety, in a substantial portion of Italian pregnant women. Our results emphasize the importance of strategies to reduce pregnancy-specific stress, as well as to diminish stress due to the pandemic. Identifying risk factors for psychological suffering is important to prevent potential long-term consequences for mothers and their offspring.

The effects of Intimate Partner Violence and a history of Childhood Abuse on Mental Health and Stress during Pregnancy

PURPOSE

Maternal adverse childhood experiences (ACEs) and intimate partner violence (IPV) are temporally distinct risk factors that negatively impact mothers and their offspring. Risk associated with ACEs and IPV begin during pregnancy, a period of increased physical and psychological demands. The current study examined a person-centered method to empirically identify profiles of pregnant women based on type and severity of ACEs and past-year IPV. Profiles were then differentiated on psychosocial functioning indicators.

METHODS

A primarily Latinx, low socioeconomic sample of women (n = 225) completed measures assessing ACEs and past-year IPV, perceived and experienced stress, emotion regulation, and trauma-related symptoms during their third trimester. Latent profile analysis (LPA) was used to identify unique profiles of women based on seven dimensional indicators reflecting threat- and deprivation-based ACEs and IPV.

RESULTS

A 4-class solution best fit the data: (1) low probability of ACEs or IPV (64.9%), (2) childhood neglect-only (20.4%), (3) childhood abuse/neglect (10.2%), and (4) polytrauma characterized by a combination of childhood abuse, neglect, and IPV (4.4%). Women with the "childhood abuse/neglect" or "polytrauma" profiles reported more stress and symptoms than women with the "low exposure" profile. Women in the "childhood neglect-only" profile were generally similar to women in the "low exposure" profile, but did report greater difficulties in emotion regulation.

CONCLUSIONS

These results suggest that childhood abuse and IPV, exposure types involving threat, are potent correlates of stress, emotion regulation, and mental health difficulties during pregnancy. However, exposure characterized by deprivation alone generally did not increase difficulties.

Long-Term IoT-Based Maternal Monitoring: System Design and Evaluation

Pregnancy is a unique time when many mothers gain awareness of their lifestyle and its impacts on the fetus. High-quality care during pregnancy is needed to identify possible complications early and ensure the mother’s and her unborn baby’s health and well-being. Different studies have thus far proposed maternal health monitoring systems. However, they are designed for a specific health problem or are limited to questionnaires and short-term data collection methods. Moreover, the requirements and challenges have not been evaluated in long-term studies. Maternal health necessitates a comprehensive framework enabling continuous monitoring of pregnant women. In this paper, we present an Internet-of-Things (IoT)-based system to provide ubiquitous maternal health monitoring during pregnancy and postpartum. The system consists of various data collectors to track the mother’s condition, including stress, sleep, and physical activity. We carried out the full system implementation and conducted a real human subject study on pregnant women in Southwestern Finland. We then evaluated the system’s feasibility, energy efficiency, and data reliability. Our results show that the implemented system is feasible in terms of system usage during nine months. We also indicate the smartwatch, used in our study, has acceptable energy efficiency in long-term monitoring and is able to collect reliable photoplethysmography data. Finally, we discuss the integration of the presented system with the current healthcare system.

Adverse Perinatal Outcomes Predicted by Prenatal Maternal Stress Among U.S. Women at the COVID-19 Pandemic Onset

BACKGROUND

High stress prenatally contributes to poor maternal and infant well-being. The coronavirus disease 2019 (COVID-19) pandemic has created substantial stress for pregnant women.

PURPOSE

To understand whether stress experienced by women pregnant at the beginning of the pandemic was associated with a greater prevalence of adverse perinatal outcomes.

METHODS

Pregnant women across the USA aged ≥18 years old enrolled in a prospective cohort study during the pandemic onset (T1) in April-May 2020. This report focuses on the 1,367 participants who gave birth prior to July-August 2020 (T2). Hierarchical logistic regression models predicted preterm birth, small for gestational age infants, and unplanned operative delivery from T1 stress, sociodemographic, and medical factors.

RESULTS

After controlling for sociodemographic and medical factors, preterm birth was predicted by high prenatal maternal stress, delivering an infant small for gestational age was predicted by interpersonal violence and by stress related to being unprepared for birth due to the pandemic, and unplanned cesarean or operative vaginal delivery was predicted by prenatal appointment alterations, experiencing a major stressful life event, and by stress related to being unprepared for birth due to the pandemic. Independent of these associations, African American women were more likely than other groups to deliver preterm.

CONCLUSION

Pregnant women who are experiencing high stress during the COVID-19 pandemic are at risk of poorer perinatal outcomes. A longitudinal investigation is critical to determine whether prenatal maternal stress and resulting outcomes have longer-term consequences for the health and well-being of children born in the midst of the current pandemic.

Exploring fear of childbirth in Kenya through evaluation of the readability of Wijma Delivery Expectancy/Experience Questionnaire Version A (W-DEQ-A)

BACKGROUND

Several tools measuring fear of childbirth (FOC) have been developed in the last three decades, however concerns about their readability have been raised.

AIM

To explore the fear of childbirth in a sample of women of reproductive age by evaluating the readability of Wijma Delivery Expectancy/Experience Questionnaire version A (W-DEQ-A).

METHODS

The Flesch Reading Ease Formula, the Flesch-Kincaid Grade Level, the FOG Scale, the SMOG Index, the Coleman-Liau Index, the Automated Readability Index, and the Linsear Write Formula were used to evaluate the readability of the W-DEQ-A. Also, focus group discussions were held to validate the findings of the readability scales mentioned above.

FINDINGS

The SMOG Index (score = 7.6), Coleman-Liau Index (score = 7.6), and the Linsear Write Formula (score = 9.4) were easily readable by women of reproductive age who had at least secondary school education (grade 12). Concerns were raised over some terms used such as desolate and deserted, which were rarely used in day to day English language conversations.

CONCLUSIONS

In this study, participants observed that W-DEQ- A was readable if administered to expectant women with a basic secondary school certificate; but there is a need to simplify some words. It was emphasized that societal dynamics play an important role in the fear of childbirth and therefore the questionnaire should address all aspects contributing to fear of childbirth and not merely the feelings and thoughts women may have at the prospect of labor and delivery.

Stress During Pregnancy and the Development of Diseases in the offspring: A Systematic-Review and Meta-Analysis

OBJECTIVE

The goal of this systematic-review and meta-analysis was to assess whether high maternal stress during pregnancy is associated with the development of pediatric pathology.

DESIGN

Epidemiological peer-reviewed studies published in English or Spanish assessing associations between maternal stress during pregnancy and psychiatric and medical diseases were selected.

PARTICIPANTS

We retrieved 73,024 citations; 42 studies meeting inclusion criteria were assessed. Overall sample included 65,814,076 women.

FINDINGS

Overall odds ratio for the development of a medical disease was OR=1.24 (CI₉₅=1.11, 1.39), Z=3.85, p<.01. Overall odds ratio for psychiatric disorders was OR=1.28 (CI₉₅=1.06, 1.56), Z=2.54, p<.02. Multivariate meta-analysis showed a significant coefficient for autism spectrum disorder studies, B=0.42, SE=0.16, Z=2.67, p<.01. We found a significant overall effect size for autism spectrum disorder (OR=1.45 [CI₉₅=1.24, 1.70], Z=4.69, p<.01). In terms of medical diseases, studies including obesity and infantile colic presented a significant overall effect size, as OR=1.20 (CI₉₅=1.03, 1.39), Z=2.41, p<.02. The highest effect size was found regarding the first trimester (B=1.62, SE=0.16, Z=9.90, p<.01).

KEY CONCLUSIONS

We concluded that exposure to high levels of stress during pregnancy are associated with autism spectrum disorder, obesity, and infantile colic in offspring.

IMPLICATIONS FOR PRACTICE

Maternal stress during pregnancy should be addressed to tackle its potential impact in health across the life span.

Spanish validation and factor structure of the Prenatal Distress Questionnaire Revised (NuPDQ)

Background: Due to an absence of maternal stress being measured in routine prenatal care by clinicians, prenatal stress has become a serious problem which is associated with poorer obstetric outcomes, as well as worse maternal and infant health. For that reason, the aim of this study was the translation, validation and adaptation of Prenatal Distress Questionnaire Revised (NuPDQ) in a Spanish sample.Methods: Three-hundred and seventy-one pregnant women were assessed using the NuPDQ, the Prenatal Distress Questionnaire, Perceived Stress Scale and the Connor-Davidson Resilience Scale. The NuPDQ was translated into Spanish by the backtranslation method and administered to participants.Results: A confirmatory factor analysis revealed the established unidimensional structure to be a poor fit to data with the Spanish version. An exploratory factor analysis suggested a five-factor structure with 14 items. The instrument had good reliability, convergent and discriminant validity psychometric properties.Conclusions: The five-factor 14-item NuPDQ is useful to assess pregnancy-specific stress in Spanish pregnant women. It may be appropriate to use this instrument in order to identify pregnant women with high pregnancy-specific stress to try to prevent negative consequences derived from those high levels.

Developing and validating the Psychosocial Burden among people Seeking Abortion Scale (PB-SAS)

While there is a large body of research demonstrating that having an abortion is not associated with adverse mental health outcomes, less research has examined which factors may contribute to elevated levels of mental health symptoms at the time of abortion seeking. This study aims to develop and validate a new tool to measure dimensions of psychosocial burden experienced by people seeking abortion in the United States. To develop scale items, we reviewed the literature including existing measures of stress and anxiety and conducted interviews with experts in abortion care and with patients seeking abortion. Thirty-five items were administered to 784 people seeking abortion at four facilities located in three U.S. states. We used exploratory factor analysis (EFA) to reduce items and identify key domains of psychosocial burden. We assessed the predictive validity of the overall scale and each sub-scale, by assessing their associations with validated measures of perceived stress, anxiety, and depression using multivariable linear regression models. Factor analyses revealed a 12-item factor solution measuring psychosocial burden seeking abortion, with four subdomains: structural challenges, pregnancy decision-making, lack of autonomy, and others' reactions to the pregnancy. The alpha reliability coefficients were acceptable for the overall scale (α = 0.83) and each subscale (ranging from α = 0.82-0.85). In adjusted analyses, the overall scale was significantly associated with stress, anxiety and depression; each subscale was also significantly associated with each mental health outcome. This new scale offers a practical tool for providers and researchers to empirically document the factors associated with people's psychological well-being at the time of seeking an abortion. Findings suggest that the same restrictions that claim to protect people from mental health harm may be increasing people's psychosocial burden and contributing to adverse psychological outcomes at the time of seeking abortion.

A Viewpoint: Validation of Self-Reported Anxiety Screening Scales in Perinatal Populations- Outstanding Issues in the Validation Research Agenda

In the absence of perinatal anxiety screening, clinically significant symptoms of anxiety remain under-detected and undertreated during perinatal period. Perinatal anxiety has a significant and far reaching impact on mothers and their children. There are well established recommendations for routine mental health screening during the perinatal period, yet less than one in five of providers routinely screen and one in seven women receive the mental health intervention they need. The validity of anxiety screening scales needs to be ascertained by criterion validity parameters such as sensitivity, specificity, and predictive values. Criterion validity, which is assessed against a reference standard, allows clear interpretation of screening results, supporting their integration with clinical care pathways. However, few existing validation studies of anxiety scales in perinatal populations examined criterion validity. Construct validity of anxiety scales, the focus of existing validation studies, does not use reference standard; thus, it lacks clear clinical interpretability for screening application. Future validation studies should focus on assessing the criterion validity of anxiety scales in perinatal populations. This will help nurses, midwives, and other members of interdisciplinary teams to clarify scale validity, interpretation, and utility for screening women for anxiety in the perinatal period.

Pregnancy-related anxiety among Chinese pregnant women in mid-late pregnancy under the two-child policy and its significant correlates

BACKGROUND

Pregnancy-related anxiety (PRA) is a global public health concern. This study aims to understand the PRA among Chinese pregnant women at mid-late pregnancy and to explore the significant correlates.

METHODS

The Chinese PRA scale was used to measure PRA among 342 pregnant women from Zhejiang Province in China at their mid- and late- pregnancy respectively.

RESULTS

The participants aged from 21 to 42 years old, and their mean age was 30. 1 (SD=4. 0). The average scores of the Chinese PRA scale at mid- and late- pregnancy were 1. 60 (SD=0. 33) and 1. 58 (SD=0. 33) respectively. Unplanned pregnancy (mid-pregnancy: β=0. 18, p<0. 001; late-pregnancy: β=0. 11, p = 0. 024) and gender of the first child being male (mid-pregnancy:β=-0. 20, p = 0. 001; late-pregnancy: β=-0. 14, p = 0. 016) were significantly correlated with PRA among pregnant women at mid- and late- pregnancy. Living with parents-in-law was not associated with the PRA overall and domain scores.

LIMITATIONS

This study was done among pregnant women at their mid-late pregnancy, and no follow-up was conducted at postpartum. The sample size of this study was relatively small which might affect the generalizability of the findings.

CONCLUSIONS

The current study found that the correlates of PRA at mid- and late-pregnancy were generally similar. For future studies, special attention should be paid to pregnant women who are in the condition of unplanned pregnancy and those who already have a female child to relieve their anxiety levels.

Development and validation of the prenatal activity restriction stress questionnaire: a Rasch rating scale analysis

Background

Antepartum activity restriction (AAR) is a common recommendation given to women at risk for preterm delivery. However, such treatment has been shown to cause heavy emotional burdens on the women receiving it since it requires them to face many challenges derived from the intervention. Nevertheless, current existing scales lack effective items that can reflect the distress of these women. The aim of this study was to develop a reliable instrument to assess the distress of women experiencing AAR.

Method

The Prenatal Activity Restriction Stress Questionnaire (PARSQ) was developed according to comprehensive literature review, women’s interviews, and existing pregnancy-special stress scales from August 2016 to July 2017 in southern Taiwan. Six experts evaluated its content validity; the Rasch rating scale model (RSM) was used to examine its item-fit, dimensionality, and reliability with 200 women with AAR experience. Furthermore, the concurrent validity was assessed through computing the correlation of AAR women’s scores on the PARSQ and Perceived Stress Scale (PSS), and discriminant validity of the PARSQ was assessed to compare the scores’ differences between the AAR women and the healthy pregnant women.

Results

The PARSQ was constructed with 23 items in the 4-dimensional scale: Role function changes (8 items), Fetal safety and health (5 items), Physical and psychological care issues (5 items), and Socioeconomic and medical issues (5 items). It was confirmed to have satisfactory content vitality (CVI = 0.78 to 1.0), reasonable item-fit (0.77 to 1.51), and good reliability in RSM model, as well as adequate concurrent validity (p = 0.005) and discriminant validity (p < 0.001).

Conclusions

Understanding the distress of women undergoing AAR is necessary for developing appropriate prenatal care to assist women in coping with their situation to alleviate their emotional burdens. The developed PARSQ with satisfied psychometric properties can be an informative instrument for clinicians/researchers to assess the specific stress of pregnant women with AAR.

Identifying fear of childbirth in a UK population: qualitative examination of the clarity and acceptability of existing measurement tools in a small UK sample

Background

Fear of childbirth is related to but not synonymous with general anxiety, and represents a superior predictor for maternal and infant outcomes. There is a need to improve the identification and provision of support for women experiencing high fear of childbirth. However it is uncertain as to whether existing measurement tools have appropriate content validity (i.e. cover the relevant domains within the construct), practical utility, and whether they are acceptable for use with a UK population. This study aimed to (1) identify the utility and acceptability of existing measures of fear of childbirth (FOC) with a small UK sample and (2) map the content of existing measures to the key concepts of fear of childbirth established by previous research.

Methods

Ten pregnant women; five with high and five with low fear of childbirth participated in a cognitive interview covering four most commonly used measures of fear of childbirth: 1. The Wijma Delivery Expectancy Questionnaire (WDEQ A), 2. The Oxford Worries about Labour Scale (OWLS), 3. The Slade-Pais Expectations of Childbirth Scale – fear subscale (SPECS) and 4. The Fear of Birth scale (FOBS). Each measure was also reviewed by participants for ease and clarity of understanding and acceptability. The measures were then reviewed against the key domains identified in the fear of childbirth literature to ascertain the adequacy of content validity of each measure. Interviews were analysed using thematic analysis for each scale item.

Results

All measures except the FOBS, included items that either women did not understand or, if where there was understanding the meanings were inconsistent across women. All measures demonstrated limited acceptability and content validity for the specific construct of FOC. Therefore, none of the measurement tools currently used within the UK met criteria for understanding, acceptability and content validity for measurement of FOC.

Conclusions

Findings emphasise a need to develop a specific fear of childbirth tool with good clarity which demonstrates appropriate content validity, and that is acceptable in presentation and length for pregnant women in a UK population.

Psychometric Properties and Factor Structure of the Persian Version of Revised Prenatal Distress Questionnaire in Second and Third Trimesters

Background:

There are no proper tools for measuring pregnancy-specific stress in Iranian population. The aim of this study was psychometric evaluation of the Persian version of Revised Prenatal Distress Questionnaire (NuPDQ) for the first time in Iranian society.

Materials and Methods:

In a descriptive-analytic study, 269 pregnant women completed the NUPDQ at Obstetrics clinics of Mazanderan Province, Iran. The reliability of the 12-item NuPDQ and 17-item NuPDQ was reevaluated using Cronbach's alpha and internal consistency. Concurrent validity was assessed using the Spielberger state-anxiety Inventory. Moreover, exploratory factor analysis was used to assess the structural factors of the questionnaire.

Results:

Factor analysis revealed that the 12-item NuPDQ consisted of four areas in the second trimester including medical and financial problem, physical symptoms, infant health, and parenting with the explained variance of 64.15%. The Persian version of 17-item NuPDQ consisted of 5 areas in the third trimester, including medical and financial problems, physical symptoms, infant health, parenting, and labor and delivery with an explained variance of 61.94%. In addition, interclass correlation coefficient in all 4 areas and overall scale score exceeded 0.90. Finally, the reliability was high based on Cronbach's alpha of 0.78 for 12-item NuPDQ and 0.79 for 17-item NuPDQ.

Conclusions:

The Persian version of 12-item NuPDQ in the second trimester and 17-item NuPDQ in the third trimester, as well as all the extracted subscales, had a good validity and reliability for assessing pregnancy-specific stress in Iranian society and can be used in clinical practice.

Validation of the Italian version of the Revised Prenatal Coping Inventory (NuPCI) and its correlations with pregnancy-specific stress

Background

Pregnancy is a period of happiness but also of physical and psychological changes that can lead to distress. Functional coping strategies can reduce the pregnancy specific-stress. This study aimed to assess the psychometric properties of the Revised Prenatal Coping Inventory (NuPCI) in an Italian sample and to investigate how coping strategies were associated with pregnancy-specific stress.

Methods

In this cross-sectional study, low-risk pregnant women (N = 211) were assessed with NuPCI, NuPDQ (Revised-Prenatal Distress Questionnaire), Brief-COPE (Coping Orientation to the Problems Experienced), and STAI (State-Trait Anxiety Inventory). The reliability of NuPCI was evaluated by assessing its internal consistency and factor structure (with a Confirmatory Factor Analysis, CFA). The concurrent validity between NuPCI and Brief-COPE and NuPDQ and STAI was investigated. Lastly, the relationship between NuPCI and NuPDQ was analyzed, as well as the ability of these scales to predict Apgar score at birth.

Results

Internal consistency of NuPCI scales was good for Planning-Preparation (ɑ_C=0.84) and Spiritual-Positive Coping (ɑ_C=0.81) scales, acceptable for Avoidance (ɑ_C=0.76) scale. Moreover, the original three-factor structure was confirmed using a CFA with 29 of the 32 items (χ²₃₇₄ = 618.06; RMSEA = 0.056, 95% confidence interval: [0.048, 0.063]); CFI = 0.920; and TLI = 0.913). Statistically significant correlations between NuPCI scales and Brief-COPE subscales ranged between r = + 0.217 and r = + 0.624; also, NuPDQ score was positively correlated with STAI scales (State scale: r = + 0.539; Trait scale: r = + 0.462). Concurrent validity was confirmed reporting that NuPDQ score was predicted by NuPCI scores (R² = 0.423, p < 0.001), positively by Avoidance (β=+0.572) and Planning-Preparation (β=+0.215) and negatively by Spiritual-Positive Coping (β=-0.132). Finally, considering the stress, the effect of the Avoidance and Spiritual-Positive Coping scores respectively in decreasing (+ 155%) and increasing (+ 16%) the Apgar score became stronger.

Conclusions

Italian NuPCI has sound psychometric properties and it is a useful coping measure. NuPDQ showed also a good validity. Our results may suggest a significant role for coping strategies, particularly in modulating the condition of the newborn at birth.

Design and Psychometric Analysis of the Stressors and Modulators of Gestational Stress Inventory (SMGSI)

Gestational stress is associated with many maternal and child complications, however, this association must be taken with care, since there are studies that find inconsistent results between stress measures and maternal complications. It is believed that the lack of convergence is due to the way in which gestational stress is evaluated.The aim of the present study was to design and validate an instrument based on a bio-psycho-social model of gestational stress. The design and validation process of the inventory was divided into four phases: (a) Construction of the items bank and content validity, (b) construct validity, (c) inventory reliability and (d) convergent and discriminant validity with psychometric instruments that have been used in other investigations to evaluate gestational stress.A valid and reliable Stressors and Modulators of Gestational Stress Inventory (SMGSI) conformed by two scales was developed: (a) Gestational stressors, which is formed by two factors, the psychological stressors and social stressors with a variance of 48.5% and 51.8% and a reliability of .79 and .67, respectively; and (b) gestational stress modulators integrated by 8 items that explain 55.2% of the variance and with a reliability of .92. In conclusion, a valid and reliable tool was obtained that measures gestational stress from a bio-psycho-social perspective. This inventory allows for the identification of allostatic and pantostatic stress, making it useful as a diagnostic tool to prevent maternal and childhood complications that are associated with chronic gestational stress.

Associations of perceived prenatal stress and adverse pregnancy outcomes with perceived stress years after delivery

Maternal stress is a risk factor for adverse pregnancy outcomes (APOs). This study evaluates the associations of prenatal stress and APOs with maternal stress years after pregnancy. The 10-item Perceived Stress Scale (PSS) (0-40 range) was completed in the first and third trimesters, and 2-7 years after delivery among a subsample (n = 4161) of nulliparous women enrolled at eight US medical centers between 2010 and 2013 in a prospective, observational cohort study. Demographics, medical history, and presence of APOs (gestational diabetes (GDM), hypertensive disorders of pregnancy (HDP), preeclampsia (PE), and medically indicated or spontaneous preterm birth (miPTB, sPTB)) were obtained. The associations of prenatal PSS and the presence of APOs with PSS scores years after delivery were estimated using multivariable linear regression. Mean PSS scores were 12.5 (95% CI 12.3, 12.7) and 11.3 (95% CI 11.1, 11.5) in the first and third trimesters respectively and 14.9 (95% CI 14.7, 15.1) 2-7 years later, an average increase of 2.4 points (95% CI 2.2, 2.6) from the start of pregnancy. Regressing PSS scores after delivery on first-trimester PSS and PSS increase through pregnancy showed positive associations, with coefficients (95% CI) of 2.8 (2.7, 3.0) and 1.5 (1.3, 1.7) per 5-point change, respectively. Adding APO indicator variables separately showed higher PSS scores for women with HDP (0.7 [0.1, 1.3]), PE (1.3 [0.6, 2.1]), and miPTB (1.3 [0.2, 2.4]), but not those with GDM or sPTB. In this geographically and demographically diverse sample, prenatal stress and some APOs were positively associated with stress levels 2-7 years after pregnancy.ClinicalTrials.gov Registration number NCT02231398.

A comparison of the Fear of Childbirth Scale with the Tilburg Pregnancy Distress Scale to identify childbirth-related fear in a sample of Dutch pregnant women: a diagnostic accuracy comparative cross-sectional study

BACKGROUND

Because of the considerable negative effects of women's childbirth-related anxiety, fear and worries, and the time constraints that midwives perceive to assess women's antenatal emotional wellbeing, it is important that midwives can identify women with a more severe fear of birth with an easy to administer, validated tool.

OBJECTIVE

To investigate the ability of the two-item Fear of Childbirth Scale (FOBS) to discriminate between pregnant women with and without birth-related fear, compared with the 16-item Tilburg Pregnancy Distress Scale (TPDS).

METHODS

A diagnostic accuracy comparative cross-sectional study was performed, comparing two screening tests. Sensitivity, specificity, positive and negative predictive values and accuracy and discriminant property of the FOBS were determined and compared with the TPDS and with the negative affect 11-items TPDS (TPDS-NA) subscale. The TPDS and TPDS-NA were treated as reference standard to establish the discriminative potential of the FOBS for the presence or absence of antenatal birth-related fear.

PARTICIPANTS

A sample of 396 Dutch women with uncomplicated pregnancies.

RESULTS

When compared with the 16-items TPDS, the FOBS showed a higher specificity (95%) than sensitivity (70%) to detect fear of childbirth. The FOBS items had a good predictive ability for fear and worries about the forthcoming birth (79%) and a conclusive ability for negative case-finding (92%). The FOBS showed good accuracy (89%). The FOBS discriminated women who were or were not classified as being fearful according to the TPDS (AUC .86). When compared with the 11 items TPDS-NA subscale, the FOBS validity and accuracy decreased: sensitivity: 51%; specificity 92%; positive predictive ability 65%; negative predictive ability 88%; accuracy 83%; AUC .82.

CONCLUSION

When compared with the 16-items TPDS, the two-item FOBS shows to be an accurate tool for identifying the presence of antenatal birth-related fear in a sample of Dutch women with uncomplicated pregnancies.
