Perinatal distress in women in low- and middle-income countries: allostatic load as a framework to examine the effect of perinatal distress on preterm birth and infant health

Allostatic Load as a Mediator and Perceived Chronic Stress as a Moderator in the Association between Maternal Mental Health and Preterm Birth: A Prospective Cohort Study of Pregnant Women in Pakistan

INTRODUCTION

The complex biopsychosocial pathways linking maternal mental health with preterm birth (PTB) are not well understood. This study aimed to explore allostatic load (AL) as a mediator and perceived chronic stress as a moderator in the pathway linking maternal mental health and PTB.

METHODS

A cohort study of pregnant women (n = 1,567) recruited at clinic visits within 10-19 weeks of gestation was assessed for maternal mental health (i.e., pregnancy-related anxiety, state anxiety, depressive symptoms) and perceived chronic stress. Blood pressure and levels of cortisol, total cholesterol, C-reactive protein, and glycosylated hemoglobin were used to create a composite measure of AL.

RESULTS

AL had the most significant effect on PTB (odds ratio (OR) = 1.84, 95% CI = 1.26-12.67, p = 0.001), while systolic blood pressure emerged as the only significant individual marker using variable selection (OR = 22%, 95% CI = 1.06-1.40, p < 0.001) in multiple logistic regression analysis. A mediation analysis revealed that maternal mental health did not have a significant direct effect on PTB (p = 0.824), but its indirect effect mediated by AL was significant (z = 2.33, p < 0.020). Low and high levels of perceived chronic stress, relative to the mean, moderated this indirect effect (z = 3.66, p < 0.001).

CONCLUSIONS

AL has a significant direct influence on PTB and mediates the effect of maternal mental health on PTB; however, the indirect effect of AL is indistinguishable between women with higher or lower levels of perceived chronic stress than normal.

Women's fertility and allostatic load in the post-reproductive years: An analysis of the Indonesian Family Life Survey

We know little about the effects of the reproductive health burden in contexts where unsafe abortions, miscarriages, stillbirths, and low-quality maternal care are common. The aim of this study is to investigate the use of allostatic load to understand the impact of reproductive histories on later-life health. We applied path models to the Indonesian Family Life Survey with a sample of 2,001 women aged 40+. Although number of children was not associated with allostatic load, pregnancies not ending in live birth and parenthood before age 18 were both negatively associated with health. We also identified clear cohort and educational effects and a possible rural advantage. Our contribution is twofold: we highlight the importance of reproductive histories beyond live births on women's later-life health in a context of increasing population ageing, and we demonstrate the applicability of using allostatic load to measure health outside the Global North.

A systematic review of clinical psychological guidance for perinatal mental health

BACKGROUND

Guidelines on psychological and/or psychosocial assessment and intervention in the perinatal period can provide beneficial practice guidance for healthcare professions to reduce maternal distress and potential mortality. As little is known about the similarities in recommendations across guidelines, which could impact the quality of therapeutic intervention women receive, this systematic review was conducted to draw out the consistent guidance for perinatal psychological and/or psychosocial therapeutic input.

METHOD

Eight literature and two guideline databases were searched alongside guideline development institutions, and organisations of maternity or perinatal mental health care. All relevant guidance was searched for and extracted before guideline quality was assessed using the AGREE-II instrument. Included guidelines had a primary or secondary focus on psychological assessment and therapeutic intervention for perinatal mental health difficulties. Using a narrative synthesis approach, recommendation consistencies and inconsistencies were outlined.

RESULTS

From the 92 records screened, seven guidelines met the inclusion criteria. Only two guidelines were rated high (> 80%) across all assessed domains, with the other guidelines scoring between poor and excellent across domains. Highest rated domains across all seven guidelines were clarity of presentation (75%) and scope and purpose (70%). Recommendations for structured psychological assessment and intervention were most commonly reported in the guidelines; however, the level of detail and depth of information varied across guidelines. Whilst assessment and intervention recommendations for mother-infant dyad and partners were considered, research into working therapeutically with these client groups in perinatal mental health services is only just emerging. Hence, guideline recommendations for working with the mother-infant dyad and partners were based on consensus of expert opinion.

CONCLUSION

Perinatal mental health guidelines were consistent in scope but showed considerable variability in quality and depth of recommendations, which could have implications for standards of clinical practice. However, there is still a need to improve the evidence underpinning recommendations in perinatal mental health guidelines to advance the implementation of psychological and/or psychosocial interventions. High quality interventions in the perinatal period could improve outcomes for women and their families.

Influence of perinatal distress on adverse birth outcomes: A prospective study in the Tigray region, northern Ethiopia

BACKGROUND

In low-income countries, where socioeconomic adversities and perinatal distress are common, adverse birth outcomes are significant public health problems. In these settings, perinatal distress, i.e., high symptoms of anxiety, depression, and/or stress during pregnancy, may be linked with adverse birth outcomes. However, few prospective studies have investigated the impact of perinatal distress on adverse birth outcomes such as preterm birth (gestational age <37 weeks), low birth weight (<2.5 kg), and small for gestational age birth (birth weight below the 10th percentile for gestational age and sex).

OBJECTIVES

Our main objective was to assess the influence of perinatal distress on adverse birth outcomes. Secondly, to investigate if perinatal distress is an independent risk factor or a mediator in the pathway between socioeconomic adversity and adverse birth outcomes.

METHODS

In a prospective cohort study following 991 women from before 20 weeks of gestation until delivery in northern Ethiopia, we collected self-reported data on distress at a mean of 14.8 (standard deviation [SD] = 1.9) and 33.9 (SD = 1.1) weeks of gestation. Distress was measured using the Edinburgh Postnatal Depression Scale, the anxiety subscale of the Hospital Anxiety and Depression Scale, and the Perceived Stress Scale. To determine birth outcomes, gestational age was estimated from the last menstrual period, fundal palpation, and/or ultrasound, while birth weight was obtained from delivery records and measured within three days after birth for those delivered at home. Logistic regression and mediation analysis were employed to evaluate the impact of perinatal distress on adverse birth outcomes.

RESULTS

Perinatal anxiety (OR [95% CI] 1.08 [1.02, 1.13]), depression (1.07 [1.03, 1.11]), stress (1.14 [1.07, 1.22]), and total distress (1.15 [1.07, 1.23]) were all associated with low birth weight, and small for gestational age birth but none did with preterm birth. Mediation analysis demonstrated that perinatal distress was a mediator in the pathway between socioeconomic adversity and adverse birth outcomes.

CONCLUSION

Our study revealed that perinatal distress was linked with adverse birth outcomes and acted as a mediator between socioeconomic adversity and these outcomes. Our findings highlight the importance of screening women for distress and providing appropriate interventions, focusing on women experiencing socioeconomic adversity. Integrating mental health services into primary maternal care in low-income countries could be an effective approach to achieve this.

Stress, social support, and racial differences: Dominant drivers of exclusive breastfeeding

Exclusive breastfeeding is recommended for 6 months; however, many childbearing people wean their infants before 6 months. Psychosocial factors such as stress, social support and race are significant determinants of breastfeeding; however, few studies have longitudinally explored the effect of perceived stress and various forms of social support on exclusive breastfeeding. We used quantitative methodologies to examine exclusive breastfeeding, perceived stress and social support among 251 participants from the Postpartum Mothers Mobile Study. Participants between 18 and 44 years were recruited during pregnancy (irrespective of parity) and completed surveys in real-time via Ecological Momentary Assessment up to 12 months postpartum from December 2017 to August 2021. We measured perceived stress with the adapted Perceived Stress Scale and perceived social support with the Multi-dimensional Social Support Scale. Received social support was measured using a single question on breastfeeding support. We conducted a mixed-effects logistic regression to determine the effect of stress, race and social support on exclusive breastfeeding over 6 months. We examined the moderation effect of perceived social support and breastfeeding support in the relationship between perceived stress and exclusive breastfeeding. Black, compared with White, participants were less likely to breastfeed exclusively for 6 months. Participants who reported higher perceived stress were less likely to breastfeed exclusively for 6 months. Perceived social support moderated the relationship between perceived stress and exclusive breastfeeding (odds ratio: 0.01, 95% confidence interval: 0.001-0.072). However, breastfeeding support directly increased the likelihood of exclusive breastfeeding over 6 months. Perceived stress is negatively associated with exclusive breastfeeding. Birthing people who intend to breastfeed may benefit from perinatal support programs that include components to buffer stress.

The feasibility and acceptability of Project POWER: a mindfulness-infused, cognitive-behavioral group intervention to address mental and sexual health needs of young pregnant women in Liberia

BACKGROUND

Following 14 years of civil war in Liberia, war exposure, gender-based violence, and extreme poverty have been identified as key challenges affecting the mental and sexual health of young pregnant women and the health of their unborn children. Despite ongoing efforts to rebuild the country's healthcare infrastructure, empirical and culturally tailored interventions to address the consequences of war are severely limited. To address these concerns, we developed Project POWER (Progressing Our Well-being, Emotions, and Relationships), a mindfulness-infused, cognitive-behavioral intervention for young adult pregnant women. This study sought to 1) assess the feasibility and acceptability of POWER and 2) determine the preliminary efficacy of POWER for improving mental and sexual health outcomes among Liberian war-exposed young adult pregnant women.

METHODS

Eighty-seven women aged 18-25 were recruited from three catchment areas in Monrovia, Liberia to participate in a two-condition, pre-post design quasi-experimental pilot trial. Participants were allocated to the intervention (POWER) or the control condition (a health education program) based on where they resided relative to the catchment areas. Each condition completed a ten-session program delivered over 5-weeks. Feasibility and acceptability of POWER were examined using program logs (e.g., the number of participants screened and enrolled, facilitator satisfaction, etc.) and data from an end-of-program exit interview. The preliminary efficacy of POWER on mental and sexual health outcomes was assessed using repeated measures ANOVA with time and condition as factors.

RESULTS

Analyses provided preliminary support for the feasibility and acceptability of POWER. Participants attended an average of 8.99 sessions out of 10 and practiced material outside the sessions at least 2.77 times per week. Women in both conditions showed significant reductions in the level of prenatal distress (baseline, M = 16.84, 3-month assessment, M = 12.24), severity of post-traumatic stress disorder (PTSD) symptoms (baseline, M = 11.97, 3-month assessment, M = 9.79),), and the number of transactional sexual behaviors (baseline, M = 1.37, 3-month assessment, M = .94) over time. Participants who received POWER showed significant reductions in the frequency of depressive symptoms (baseline, M = 5.09, 3-month assessment, M = 2.63) over women in the control condition.

CONCLUSIONS

Findings suggest that POWER may be a feasible and acceptable intervention to promote mental and sexual health for young adult pregnant women in Liberia. However, fully powered clinical trials are still needed to determine the efficacy and effectiveness of POWER before recommending its use on a larger scale in Liberia.

Effects of intrauterine exposure to SARS-CoV-2 on infants' development: a rapid review and meta-analysis

Potential medium- and long-term neurodevelopmental sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during pregnancy have not been ruled out. We aimed to systematically review and summarize the evidence regarding the effects of intrauterine exposure to SARS-CoV-2 on infant development and behavior. Scopus, PubMed, Web of Science, CINAHL, and PsycNet databases were searched for studies published up to February 6, 2023, investigating the effects of gestational SARS-CoV-2 on infant development and behavior. We performed narrative synthesis according to updated protocols. Studies using comparison groups and with the Ages and Stages Questionnaires-Third Edition (ASQ-3) scores available were included in a meta-analysis performed according to Cochrane protocols. We used the Newcastle-Ottawa Quality Assessment Scale to analyze the risk of bias. Heterogeneity was calculated using the I² statistic. The search identified 2,782 studies. After removing duplicates and applying the eligibility criteria, we performed a narrative synthesis of 10 included studies and a meta-analysis of three. There was no evidence of higher developmental delay rates in infants exposed to SARS-CoV-2 during pregnancy compared to non-exposed infants. However, the exposed infants scored lower than either the non-exposed children or pre-pandemic cohorts in some domains. Pooled results from the random-effects model indicated that SARS-CoV-2-exposed infants had lower scores on fine motor (mean difference [MD] = -4.70, 95% confidence interval [CI]: -8.76; -0.63), and problem-solving (MD = -3.05, 95% CI: -5.88; -0.22) domains than non-exposed infants (heterogeneity: I² = 69% and 88%, respectively). There was no difference between the exposed and non-exposed infants in the communication, gross motor, and personal-social ASQ-3 domains.  Conclusion: We did not find evidence confirming the association between SARS-CoV-2 gestational exposure and neurodevelopmental delays. However, the meta-analysis indicated that gestational exposure negatively affected fine motor and problem-solving skills. Robust evidence on this topic is still incipient, and the available studies present methodological inconsistencies that limit the drawing of clear-cut conclusions.   PROSPERO registration: #CRD42022308002; March 14, 2022. What is Known: • COVID-19 is associated with adverse pregnancy outcomes potentially linked to neurodevelopmental delays. • SARS-CoV-2 vertical transmission is rare; however, infections during pregnancy can be deleterious to the fetus, possibly mediated by maternal immune activation and other inflammatory mechanisms. What is New: • No evidence of increased developmental delay rates among SARS-CoV-2 gestational-exposed infants was found. However, a meta-analysis of three studies showed lower scores in fine motor and personal social ASQ-3 domains among exposed infants. • SARS-CoV-2 gestational exposure and the pandemic can affect child development via many mechanisms. Potential neurodevelopmental sequelae of SARS-CoV-2 exposure during gestation have not been ruled out.

Prenatal allostatic load and preterm birth: A systematic review

Objective

Allostatic load refers to cumulative neuroendocrine burden and has been postulated to mediate and moderate physiological and psychological stress-related responses. This may have important implications for the risk of preterm birth. This systematic review examines the evidence on the association between prenatal allostatic load and preterm birth.

Data sources

A comprehensive search of seven electronic databases was conducted from inception to August 23, 2022 to identify all English-language observational and mixed methods studies examining allostatic load and preterm birth with no year or geographic restrictions.

Study eligibility criteria

Studies were included if they measured allostatic load, evaluated as the cumulative effect of any combination of more than one allostatic load biomarker, during pregnancy. Studies must have observed preterm birth, defined as &lt; 37 weeks' gestational age, as a primary or secondary outcome of interest.

Study appraisal and synthesis methods

The Quality In Prognosis Studies tool was used to evaluate risk of bias within included studies. A narrative synthesis was conducted to explore potential associations between allostatic load and preterm birth, and sources of heterogeneity.

Results

Three prospective cohort studies were identified and revealed mixed evidence for an association between allostatic load and preterm birth. One study reported a statistically significant association while the other two studies reported little to no evidence for an association. Heterogeneity in when and how allostatic load was measured, limitations in study design and cohort socio-demographics may have contributed to the mixed evidence.

Conclusions

This review provides insight into key individual-, community-, and study-level characteristics that may influence the association between allostatic load and preterm birth. Knowledge gaps are identified as foci for future research, including heterogeneity in allostatic load biomarkers and allostatic load index algorithms as well as pregnancy-specific considerations for allostatic load measurement. Further investigation of the allostatic load framework in the context of perinatal mental health is needed to advance understandings of maternal, infant, and child health.

Associations Between Implementation of the Collaborative Care Model and Disparities in Perinatal Depression Care

OBJECTIVE

To evaluate whether perinatal collaborative care model implementation was associated with a reduction in racial disparities in depression care.

METHODS

This retrospective cohort study included pregnant and postpartum people who self-identified as either Black or White, and received prenatal care at academic faculty offices affiliated with an urban quaternary medical center. Individuals were divided into two cohorts to reflect the epochs of implementation. The primary outcome was the frequency of depression screening. The secondary outcome was the frequency of provision of a treatment recommendation for those with a positive depression screen. Antenatal and postpartum care were analyzed separately. A propensity score was used in multivariable models to control for confounders chosen a priori across implementation epoch. Interaction terms were created between race and implementation epoch to identify whether effect modification was present. Subgroup analyses were performed for outcomes with significant race-by-epoch interaction terms.

RESULTS

Of the 4,710 individuals included in these analyses, 4,135 (87.8%) self-identified as White and 575 (12.2%) self-identified as Black. Before implementation, Black individuals were more likely to receive screening (adjusted odds ratio [aOR] 2.44) but less likely to have a treatment recommended when a positive screen was identified (aOR 0.05). In multivariable models, race-by-epoch interaction terms were significant for both antenatal screening (P<.001) and antenatal treatment recommendation (P=.045), demonstrating that implementation of the perinatal collaborative care model was associated with reductions in extant racial disparities. After implementation, there were no significant differences by race (referent=White) in screening for antenatal depression (aOR 1.22, 95% CI 0.89-1.68) or treatment recommendations for those who screened positive (aOR 0.64, 95% CI 0.27-1.53). Race-by-epoch interaction terms were not significant in multivariable models for either postpartum screening or treatment recommendation.

CONCLUSION

Implementation of the perinatal collaborative care model is associated with a mitigation of racial disparities in antenatal depression care and may be an equity-promoting intervention for maternal health.

Obstetric risk in pregnancy interacts with hair cortisone levels to reduce gestational length

Background

Maternal psychological stress has been linked to preterm birth. However, the differential contribution of psychological stress versus stress hormones is not clear. Studies focus primarily on perceived stress and cortisol, with few assessing its inter-convertible hormone cortisone. Furthermore, little is known about the potential moderating roles of obstetric risk and fetal sex in the relationship between maternal stress and gestational length. This gap in knowledge is particularly evident for rural women who typically experience chronic multiple stressors during pregnancy. We explored the relationship of hormonal and psychological stress to gestational length and the effects of obstetric risks and fetal sex on this relationship among Kenyan pregnant women.

Methods

The sample included 130 women recruited between 22 to 28 weeks gestation. They completed a clinical and sociodemographic questionnaire together with the Perceived Stress Scale and provided a hair sample for cortisol and cortisone assay. Women underwent an ultrasound to assess weeks of gestation. At delivery, their pregnancy-related health problems were identified using information extracted from medical records to compile each woman's number of pregnancy risks on the Obstetric Medical Risk Index (OMRI).

Results

Perceived stress and hair cortisol were not significant predictors of gestational length. However, a greater number of obstetric risks on the OMRI was associated with shorter gestational length. This effect was further explained by the interaction between obstetric risk and hair cortisone (B = 0.709, p = 0.02). Hair cortisone levels of mothers who had a shorter gestation were significantly higher in mothers with 2 or more risks on the OMRI but not among mothers with only one or no risks (t = 2.39, p = 0.02). Fetal sex had no relationship to gestational length and also had no moderating effect on the relationship between any stress-related metric and gestational length.

Conclusion

Cortisone levels may increase in anticipation of shorter gestation as a compensatory response to increased obstetric risk. Elevated cortisone may be a more sensitive marker of risk for early delivery than cortisol or psychological stress, with salience for both the male and female fetus.

Sociodemographic Influences on Perceived Stress during Pregnancy: Results from the CCREOH Environmental Epidemiologic Study, Suriname

Screening for prenatal stress is not routine in Suriname, despite its significant impact on maternal and newborn health. This study assessed the prevalence of high perceived prenatal stress and its sociodemographic predictors in three geographic areas in Suriname. In this cross-sectional study, data from 1190 participants of the Caribbean Consortium for Research in Environmental and Occupational Health cohort study were analyzed. Cohen’s Perceived Stress Scale was completed during pregnancy to ascertain high perceived stress (cut-off score 20). The association between maternal sociodemographic factors and high perceived stress was examined using the chi-square test and logistic regression models; 27.5% of all participants had high perceived stress with statistically significant lower rates in Nickerie (18.8%) compared with Paramaribo (29.8%; p = 0.001) and the Interior (28.6%; p = 0.019). Maternal sociodemographic factors moderated the difference between the Interior and Nickerie. Participants from Paramaribo had statistically significant higher odds of high perceived stress compared to those from Nickerie, independent of their age and educational level (adjusted OR = 1.94; 95% confidence interval 1.32–2.86). Perceived stress during pregnancy is predicted by sociodemographic factors. These findings identified target groups for interventions in Suriname. Policy makers should consider integrating perceived stress assessment as a routine part of prenatal care.

The Impact of COVID-19-Related Work Stress on the Mental Health of Primary Healthcare Workers: The Mediating Effects of Social Support and Resilience

Objective

The psychological condition of healthcare workers since the COVID-19 pandemic has attracted the attention of many studies. However, few have reported on psychosocial problems of primary healthcare workers in the COVID-19 pandemic. This study aimed to examine the mediating roles of social support and resilience in COVID-19-related work stress and symptoms of anxiety and depression.

Methods

A total of 840 primary healthcare workers in 17 community health centers in Guangzhou, China, were recruited from May to July 2021. Data on demographic characteristics, COVID-19-related work stress, social support, resilience, anxiety and depression were collected. A structural equation model was used for mediation analysis.

Results

More than half of participants reported mild or more severe (at least borderline abnormal) symptoms of anxiety (68.1%) and depression (55.6%). Social support and resilience mediate the association between COVID-19-related work stress and symptoms of anxiety and depression, respectively. Furthermore, the association between work stress and symptoms of anxiety and depression was also mediated by an accumulation of social support and resilience. The indirect effect of COVID-19-related work stress on anxiety and depression through resilience was much greater than other indirect effects.

Conclusion

Anxiety and depression were prevalent among primary healthcare workers. This study highlights the psychological impact of the COVID-19-related psychosocial work environment on primary healthcare workers. There is an urgent need to improve working conditions for primary healthcare workers in the COVID-19 and to implement intervention strategies aimed at increasing individual resilience alongside the establishment of external supportive work environments.

Perinatal Mental Health; The Role and the Effect of the Partner: A Systematic Review

Pregnancy is a transitional period involving the most complex experiences in a woman's life, during which the woman's psychological status can be affected by a wide range of psychosocial variables. However, positive interpersonal relationships appear to constitute a supportive network that significantly influences perinatal mental health. Therefore, the presence of a supportive partner works psycho-protectively against the difficulties and pressures created by the transition to maternity. The aim of this study was to review systematically the influence of the partner on the woman's psychology during the perinatal period. Fourteen research articles from PubMed/Medline, Google Scholar and PsycINFO were included in the review from a total of 1846 articles. Most studies have shown a correlation between the support from the partner and prenatal depression and anxiety. Support from the spouse during childbirth is related to the extent to which women feel safe during labor as well as the stress during childbirth. The role of the partner is very important in the occurrence of perinatal mental disorders in women. Of course, more research needs to be done in the field of perinatal mental health. The risk factors that lead to mental disorders need to be clarified and the role of the partner in the perinatal period requires reinforcement and needs to be given the necessary importance.

Associations of forms of intimate partner violence with low birth weight in India: findings from a population-based Survey

BACKGROUND

Many studies report a significant association between a lifetime measure of intimate partner violence (IPV) and low birth weight (LBW) in low-income and economically developed countries. However, it remains relatively unclear how different forms of IPV affect LBW in low-income countries. This study examines the associations of various forms of IPV with two measures of birth outcomes - LBW and birth weight in India.

METHODS

This study used the National Family Health Survey (NFHS-4) 2015-2016 data of India. The analysis included 11,423 women aged 15-49 years. Using both logistic and linear regression analyses, we assessed the associations of various forms of IPV with binary and continuous measures of birth weight. The analysis controlled for several potential covariates.

RESULTS

In fully-adjusted regression models, women who experienced any IPV, compared to those who had not experienced any IPV, were 1.19 times (95% CI: 1.02-1.37) as likely to give birth to an LBW baby. Compared to those who had not experienced any physical violence (PV), women who experienced any PV were 1.16 times (95% CI: 1.00-1.35) as likely to have an LBW baby. Moreover, compared to those who had not experienced any emotional violence (EV), women who experienced any EV were 1.29 times (95% CI: 1.06-1.56) as likely to have LBW babies. Linear regression analysis found that any IPV exposure was associated with a significant decrease in birth weight in the fully-adjusted model (b = -32.39; 95% CI: -63.39 to -1.73). Further, experience of any PV (b = -28.40; 95% CI: -60.13 to 3.36) and any EV (b = -51.69; 95% CI: -93.97 to -9.42) appear to be negatively associated with a continuous measure of birth weight.

CONCLUSION

Findings have implications for public health policies and interventions that protect women from exposure to intimate partner violence for ensuring better maternal health and birth outcomes.

Affect of moringa oleifera given against pregnant and breastfeeding mothers cortisol

OBJECTIVE

This study to assess the affect of moringa oleifera given against pregnant and breastfeeding mothers cortisol.

METHOD

Sample 40 pregnant women, low education, no work statusin, the experimental method (Randomized Double Blind design), Saliva samples from nursing mothers tested by Laboratory using KIT ELISA.

RESULTS

Pre cortisol in the iron tablet and Moringa flour group was p=0.0003, post pregnancy cortisol results in the iron group and Moringa flour, p=0.119, decrement greater in the group with Moringa flour±SD 2.91±7:20, group of iron±SD 3.60±6:37, based on test of both groups the presence of the value p=0.006, at 3 months of age, p=0.923 (p>0.05) at 6 months of age p=0.496 (p>0.05), a greater decrease occurred in the Moringa flour group with a value of±SD=↓ 5.44±16.77, based on test of both groups the presence of the value p (p=0.359).

CONCLUSION

Moringa flour provides the same benefits as Fe against cortisol levels during pregnancy but not significant at the lactation.

Perceived stress may mediate the relationship between antenatal depressive symptoms and preterm birth: A pilot observational cohort study

Background

Screening for changes in pregnancy-related anxiety and depressive symptoms during pregnancy may further our understanding of the relationship between these two variables and preterm birth.

Objectives

To determine whether changes in pregnancy-related anxiety and depressive symptoms during pregnancy influence the risk of preterm birth among Pakistani women; explore whether perceived stress moderates or mediates this relationship, and examine the relationship between the various components of pregnancy-related anxiety and preterm birth.

Methods

A prospective cohort study design was used to recruit a diverse sample of 300 low-risk pregnant women from four centers of Aga Khan Hospital for Women and Children in Karachi, Pakistan. Changes in pregnancy-related anxiety and depressive symptoms during pregnancy were tested. Multiple logistic regression analysis was used to determine a predictive model for preterm birth. We then determined if the influence of perceived stress could moderate or mediate the effect of depressive symptoms on preterm birth.

Results

Changes in pregnancy-related anxiety (OR = 1.1, CI 0.97–1.17, p = 0.167) and depressive symptoms (OR = 0.9, CI 0.85–1.03, p = 0.179) were insignificant as predictors of preterm birth after adjusting for the effects of maternal education and family type. When perceived stress was added into the model, we found that changes in depressive symptoms became marginally significant after adjusting for covariates (OR = 0.9, CI 0.82–1.01, p = 0.082). After adjusting for the mediation effect of change in perceived stress, the effect of change in depressive symptoms on preterm birth were marginally significant after adjusting for covariates. Among six different dimensions of pregnancy-related anxiety, mother’s concerns about fetal health showed a trend towards being predictive of preterm birth (OR = 1.3, CI 0.97–1.72, p = 0.078).

Conclusions

There may be a relationship between perceived stress and antenatal depressive symptoms and preterm birth. This is the first study of its kind to be conducted in Pakistan. Further research is required to validate these results.

Risk of Preterm Birth and Newborn Low Birthweight in Military Women with Increased Pregnancy-Specific Anxiety

INTRODUCTION

Prenatal maternal anxiety and depression have been implicated as possible risk factors for preterm birth (PTB) and other poor birth outcomes. Within the military, maternal conditions account for 15.3% of all hospital bed days, and it is the most common diagnostic code for active duty females after mental disorders. The majority of women (97.6%) serving on active duty are women of childbearing potential. Understanding the impact that prenatal maternal anxiety and depression can have on PTB and low birthweight (LBW) in a military population is critical to providing insight into biological pathways that alter fetal development and growth. The purpose of the study was to determine the impact of pregnancy-specific anxiety and depression on PTB and LBW within a military population.

MATERIAL AND METHODS

Pregnancy-specific anxiety and depression were measured for 246 pregnant women in each trimester. Individual slopes for seven different measures of pregnancy anxiety and one depression scale were calculated using linear mixed models. Logistic regression, adjusted and unadjusted models, were applied to determine the impact on PTB and LBW.

RESULTS

For each 1/10 unit increase in the anxiety slope as it related to well-being, the risk of LBW increased by 83% after controlling for parity, PTB, and active duty status. Similarly, a 1/10 unit rise in the anxiety slope related to accepting pregnancy, labor fears, and helplessness increased the risk of PTB by 37%, 60%, and 54%, respectively.

CONCLUSIONS

Pregnancy-specific anxiety was found to significantly increase the risk of PTB and LBW in a military population. Understanding this relationship is essential in developing effective assessments and interventions. Results emphasize the importance of prenatal maternal mental health to fetal health and birth outcomes. Further research is needed to determine the specific physiological pathways that link prenatal anxiety and depression with poor birth outcomes.

Predictors of Prenatal Depression: A Cross-Sectional Study in Rural Pakistan

Objective: To determine the prevalence and association of prenatal depression with socioeconomic, demographic and personal factors among pregnant women living in Kallar Syedan, Rawalpindi, Pakistan. Methods: Five hundred women in the second and third trimester of pregnancy, living in Kallar Syedan, a rural area of district Rawalpindi Pakistan, were included in the study. Depression was assessed using "Patient health questionnaire" (PHQ9) in Urdu, with a cut-off score of 10. Multi-dimensional scale of perceived social support (MSPSS) was used to assess perceived social support. Life Events and Difficulties Schedule (LEDS) were used to measure stressful life events in past 1 year. Tool to assess intimate partner violence (IPV) was based on WHO Multi Country Study on "Women's Health and Domestic Violence against Women." Results: Prevalence of prenatal depression was found to be 27%. Number of pregnancies was significantly associated with prenatal depression (p < 0.01). Women living in a joint family and those who perceived themselves as moderately satisfied or not satisfied with their life in the next 4 years were found to be depressed (p < 0.01, OR 6.9, CI 1.77-26.73). Depressive symptomatology in women who experienced more than five stressful life events in last 1 year was three times higher (p < 0.001, OR 3.2, CI 1.68-5.98) than in women with 1-2 stressful events. Women who were supported by their significant others or their family members had 0.9 times (p < 0.01, OR 0.9, CI 0.85-0.96) less chance of getting depressed. Pregnant women who were psychologically abused by their partners were 1.5 times more depressed (p < 0.05 CI 1.12-2.51). Odds of having depression was also high in women who had less mean score of MSSI (p < 0.05, OR 1.1, CI 1.01-1.09). Women who had suitable accommodation had 0.5 times less chance of having depression than others (p < 0.05, OR 0.5, CI 0.27-0.92). Conclusion: Over a quarter of the women in the study population reported prenatal depression, which were predicted predominantly by psychosocial variables.

Comorbid Anxiety and Depression among Pregnant Pakistani Women: Higher Rates, Different Vulnerability Characteristics, and the Role of Perceived Stress

Anxiety and depression commonly co-occur during pregnancy and may increase risk of poor birth outcomes including preterm birth and low birth weight. Our understanding of rates, patterns, and predictors of comorbid anxiety and depression is hindered given the dearth of literature, particularly in low- and middle-income (LMI) countries. The aim of this study is (1) to explore the prevalence and patterns of comorbid antenatal anxiety and depressive symptoms in the mild-to-severe and moderate-to-severe categories among women in a LMI country like Pakistan and (2) to understand the risk factors for comorbid anxiety and depressive symptoms. Using a prospective cohort design, a diverse sample of 300 pregnant women from four centers of Aga Khan Hospital for Women and Children in Pakistan were enrolled in the study. Comorbid anxiety and depression during pregnancy were high and numerous factors predicted increased likelihood of comorbidity, including: (1) High level of perceived stress at any time point, (2) having 3 or more previous children, and (3) having one or more adverse childhood experiences. These risks were increased if the husband was employed in the private sector. Early identification and treatment of mental health comorbidities may contribute to decreased adverse birth outcomes in LMI countries.

Racial Differences in the Biochemical Effects of Stress in Pregnancy

Prenatal stress has been linked to preterm birth via inflammatory dysregulation. We conducted a cross-sectional study on female participants who delivered live, singleton infants at University of Pittsburgh Medical Center Magee Women’s Hospital. Participants (n = 200) were stratified by cumulative risk scores using a combination of individual factors (maternal education, diabetes, hypertension, smoking, relationship status, obesity, depression) and neighborhood deprivation scores. We hypothesized that inflammatory cytokines levels differ by risk group and race. Multiplex analyses of IL-6, IL-8, IL-10, IL-13 and TNF-alpha were run. We found that Black birthing people had more risk factors for chronic stress and had lower levels of IL-6 compared to White birthing people. When stratified by risk group and race, low-risk Black birthing people had lower levels of IL-6 compared to low-risk White birthing people, and high-risk Black birthing people had lower levels of IL-8 compared to high-risk White birthing people. Higher area deprivation scores were associated with lower IL-6 levels. Our results suggest that the relationship between chronic stress and inflammatory cytokines is modified by race. We theorize that Black birthing people encounter repetitive stress due to racism and social disadvantage which may result in stress pathway desensitization and a blunted cytokine response to future stressors.

Relationships between mental health and diet during pregnancy and birth outcomes in a lower-middle income country: "Healthy mothers, healthy communities" study in Vanuatu

Poor maternal mental health during pregnancy is associated with adverse birth outcomes, including lower birthweight and gestational age. However, few studies assess both mental health and diet, which might have interactive effects. Furthermore, most studies are in high-income countries, though patterns might differ in low- and middle-income countries (LMICs).

OBJECTIVES

To analyze relationships between mental health and diet during pregnancy with birth outcomes in Vanuatu, a lower-middle income country.

METHODS

We assessed negative emotional symptoms of depression, anxiety, and stress (referred to as "distress") and dietary diversity during pregnancy, and infant weight and gestational age at birth, among 187 women. We used multivariate linear regression to analyze independent and interactive relationships between distress, dietary diversity, and birth outcomes, controlling for sociodemographic and maternal health covariates.

RESULTS

There were no direct linear relationships between dietary diversity or distress with infant birthweight or gestational age, and no curvilinear relationships between distress and infant outcomes. We observed interactive relationships between distress and dietary diversity on birthweight, explaining 2.1% of unique variance (P = .024). High levels of distress predicted lower birthweights among women with low dietary diversity. These relationships were not evident among women with moderate or high dietary diversity.

CONCLUSIONS

Relationships between mental health and diet might underlie inconsistencies in past studies of prenatal mental health and birthweight. Results highlight the importance of maternal mental health on birthweight in LMICs. Interactive relationships between mental health and diet might ultimately point to new intervention pathways to address the persistent problem of low birthweight in LMICs.

Association of differential symptoms of stress to hair cortisol and cortisone concentrations among pregnant women in Kenya

Objectives: The purpose of this study was to characterize the stress experienced by pregnant women in Kenya and assess the relationship between perceived stress and stress-related biomarkers of cortisol and cortisone.Background: Kenyan women are exposed to multiple stressors that may result in chronic stress. However, antenatal stress has not been examined and characterized in Kenya; nor has the relationship between pregnant women's self-reported stress and stress biomarkers been established.Methods: One hundred and fifty women were recruited between 22 and 28 weeks gestation. Participants completed the Perceived Stress Scale (PSS) and a sociodemographic questionnaire. Hair samples were obtained for analysis of cortisol and cortisone. Factor analysis was used to extract unique clusters of stress symptoms from items in the PSS. Regression models were computed to examine relationships of stress to cortisone and cortisol, controlling for obstetric risk.Results: Mean age of the women was 25 years (SD = 5, ±16-41). Their degree of perceived stress and cortisol/cortisone concentrations both indicated moderate levels of stress. There was no association between general perceived stress and either hair cortisol or cortisone. However, factor analysis of the PSS identified three clusters of stress symptoms and one cluster - a woman's negative frame of mind regarding life and inefficacy in handling its problems - was associated with higher levels of cortisone (β= -.231, p = 0.011).Conclusions: Specific stress symptoms may have unique relationships to specific biomarkers and be more useful in assessment than general perceived stress. Assays of both hair cortisol and cortisone might enable a more comprehensive assessment of glucocorticoid activity and better prediction of health risks from stress.Lay summaryUnderstanding stress among rural pregnant Kenyan women may help in addressing risks during pregnancy that lead to adverse birth outcomes. Findings suggest that a woman's tendency to think negatively about life and to doubt her ability to handle life's problems are symptoms of stress that may contribute to higher levels of stress hormones. Assessing women's specific symptoms of stress and different stress hormones during pregnancy may more effectively identify women who need intervention to reduce their health risk.

Association of Maternal depression with diet: A systematic review

This review was conducted to explore the bi-directional association of maternal depression with diet. This link is hypothesized because the mental health of pregnant women may adversely affect their nutritional intake; or inversely, that poor nutritional intake during pregnancy may cause mental health issues. Seven electronic databases were searched to retrieve relevant peer-reviewed articles published during 2000-2018. Primary research studies published in English that evaluated the relationship between maternal antenatal and postnatal depression with dietary intake were selected. We screened 1585 articles, of which 13 met the inclusion criteria. These included five cohort studies (including two birth cohorts) and eight cross-sectional studies representing a total of 12,742 participants altogether. Studies were divided into five groups depending on whether they analyzed all nutrients, micronutrients, dietary patterns, dietary behavior or intake of fish and vegetables. The studies exploring the association of depression with dietary patterns found a protective association of "Health Conscious", "Healthy" and "Brazilian" diet patterns with maternal depression. The group of studies which analyzed all nutrients, found an inverse relationship of the "Healthy Eating Index" with maternal depression. Deficiency of calcium, iron, and folate were also associated with maternal depression. Prenatal and early postpartum eating attitudes and BMI were found as predictors of depressive symptoms in the late post-partum period in a diet behavior study. It is important to identify modifiable lifestyle risk factors which may contribute to maternal depression. A limitations of our review is the absence of meta-analysis which was not possible due to heterogeneity of the studies.

Adverse Childhood Experiences and Changing Levels of Psychosocial Distress Scores Across Pregnancy in Kenyan Women

Background: Adverse childhood experiences (ACEs) have been associated with deleterious effects on mental health in pregnancy. Methods: The ACE International Questionnaire (ACE-IQ) was used to measure neglect, abuse, and household dysfunction. Longitudinal mixed effect modelling was used to test the effect of ACEs on pregnancy-related anxiety, depressive symptoms, and perceived stress at two time points (12–19 and 22–29 weeks) during pregnancy. Results: A total of 215 women who were predominantly married (81%) and had attained tertiary education (96%) were enrolled. Total ACEs were significantly associated with depressive symptoms (r = 0.23, p < 0.05) and perceived stress (r = 0.18, p < 0.05). As depressive symptoms decreased, t (167) = −8.44, p < 0.001, perceived stress increased, t (167) = 4.60, p < 0.001, and pregnancy-related anxiety remained unchanged as pregnancy progressed. Contact sexual abuse (p < 0.01) and parental death or divorce (p = 0.01) were significantly associated with depression over time (p < 0.01). Total ACEs in this study were associated with depressive symptoms early but not late in pregnancy. Conclusions: Higher total ACEs were positively associated with depressive symptoms and perceived stress during pregnancy, suggesting that mental disorders may have an impact on pregnancy outcomes and ought to be addressed. Further validation of the Edinburgh Postnatal Depression Scale (EPDS) tool in local settings is required.

Ethnic disparity and exposure to supplements rather than adverse childhood experiences linked to preterm birth in Pakistani women

BACKGROUND

Adverse childhood experiences (ACEs) are associated with prenatal mental health and negative pregnancy outcomes in high income countries, but whether the same association exists in Pakistan, a low- to middle-income (LMI) country, remains unclear.

METHODS

Secondary data analyses of a prospective longitudinal cohort study examining biopsychosocial measures of 300 pregnant women at four sites in Karachi, Pakistan. A predictive multiple logistic regression model for preterm birth (PTB; i.e., <37 weeks' gestation) was developed from variables significantly (P < 0.05) or marginally (P < 0.10) associated with PTB in the bivariate analyses.

RESULTS

Of the 300 women, 263 (88%) returned for delivery and were included in the current analyses. The PTB rate was 11.1%. We found no association between ACE and PTB. Mother's education (P = 0.011), mother's ethnicity (P = 0.010), medications during pregnancy (P = 0.006), age at birth of first child or current age if primiparous (P = 0.049) and age at marriage (P = 0.091) emerged as significant in bivariate analyses. Mother's ethnicity and taking medications remained predictive of PTB in the multivariate model.

LIMITATIONS

Findings are limited by the relatively small sample size which precludes direct testing for possible interactive effects.

CONCLUSIONS

In sum, pathways to PTB for women in LMI countries may differ from those observed in high-income countries and may need to be modelled differently to include behavioural response to emotional distress and socio-cultural contexts.

Associations of antenatal maternal psychological distress with infant birth and development outcomes: Results from a South African birth cohort

BACKGROUND

Antenatal maternal psychological distress is common in low and middle-income countries (LMIC), but there is a dearth of research on its effect on birth and developmental outcomes in these settings, particularly in Sub-Saharan Africa. This study set out to identify risk factors for antenatal maternal psychological distress and determine whether antenatal maternal psychological distress was associated with infant birth and developmental outcomes, using data from the Drakenstein Child Health Study (DCHS), a birth cohort study in South Africa.

METHODS

Pregnant women were enrolled in the DCHS from primary care antenatal clinics. Antenatal maternal psychological distress was measured using the Self-Reporting Questionnaire 20-item (SRQ-20). A range of psychosocial measures, including maternal childhood trauma, depression, and posttraumatic stress disorder (PTSD) were administered. Birth outcomes, including premature birth, weight-for-age z-score and head circumference-for-age z-score, were measured using revised Fenton growth charts. The Bayley III Scales of Infant and Toddler Development was administered at 6 months of age to assess infant development outcomes, including cognitive, language, and motor domains in a subset of n=231. Associations of maternal antenatal psychological distress with psychosocial measures, and with infant birth and developmental outcomes were examined using linear regression models.

RESULTS

961 women were included in this analysis, with 197 (21%) reporting scores indicating the presence of psychological distress. Antenatal psychological distress was associated with maternal childhood trauma, antenatal depression, and PTSD, and inversely associated with partner support. No association was observed between antenatal maternal psychological distress and preterm birth or early developmental outcomes, but antenatal maternal psychological distress was associated with a smaller head circumference at birth (coefficient=-0.30, 95% CI: -0.49; -0.10).

CONCLUSION

Antenatal maternal psychological distress is common in LMIC settings and was found to be associated with key psychosocial measures during pregnancy, as well as with adverse birth outcomes, in our study population. These associations highlight the potential value of screening for antenatal maternal psychological distress as well as of developing targeted interventions.

Hospitalization of children after prenatal exposure to opioid maintenance therapy during pregnancy: a national registry study from the Czech Republic

BACKGROUND AND AIMS

Our understanding of the long-term safety of prenatal exposure to opioid maintenance treatment (OMT) is insufficient. We compared childhood morbidity (0-3 years) between OMT-exposed and relevant comparison groups.

DESIGN

Nation-wide, registry-based cohort study. Registries on reproductive health, addiction treatment, hospitalization and death were linked using identification numbers.

SETTING

The Czech Republic (2000-14).

PARTICIPANTS

Children with different prenatal exposure: (i) mother in OMT during pregnancy (OMT; n = 218), (ii) mother discontinued OMT before pregnancy (OMT-D; n = 55), (iii) mother with opioid use disorder, but not in OMT during pregnancy (OUD; n = 85) and (iv) mother in the general population (GP) (n = 1 238 452) MEASUREMENTS: Episodes of hospitalization were observed as outcomes. Information on in-patient contacts, length of stay and diagnoses (International Classification of Diseases version 10) were assessed. Binary logistic regressions were conducted to estimate the associations between OMT exposure and the outcomes, crude and adjusted for the socio-economic status and smoking.

FINDINGS

No significant differences were found in the overall proportion of hospitalization among OMT-exposed children, children of OMT-D and children of women with OUD [54.1%, 95% confidence interval (CI) = 47.3-60.1%; 47.3%, 95% CI = 33.9-61.1%; 51.8%, 95% CI = 40.7%-62.6%], while the proportion was significantly lower (35.8%, 95% CI = 35.7-35.8%) in the GP. There were no significant differences in risk of specific diagnoses between OMT-exposed children, children of OMT-D and children of women with OUD. In the adjusted analyses, differences between OMT-exposed and children in the GP were still present for infections and parasitic diseases (OR = 2.0, 95% CI = 1.4-2.7), diseases of the digestive system (OR = 1.7, 95% CI = 1.2-2.6) and diseases of the skin and subcutaneous tissue (OR = 1.9, 95% CI = 1.2-3.2).

CONCLUSION

This study did not find clear evidence for an increase in risk of morbidity during the first 3 years of life in children with prenatal opioid maintenance treatment exposure compared with children of women who discontinued such treatment before pregnancy or suffered from opioid use disorder without this treatment. Compared the general population, there appears to be an increased risk of hospitalizations for infectious, gastrointestinal and skin diseases.

Do pregnant women living in higher well-being populations in the USA experience lower risk of preterm delivery? A cross-sectional study

OBJECTIVE

To determine if preterm birth, defined as gestational age <37 weeks, is lower for women living in counties with higher well-being, after accounting for known individual risk factors.

DESIGN

Cross-sectional study of all US births in 2011.

PARTICIPANTS

We obtained birth data from the National Center for Health Statistics which included 3 938 985 individuals.

MAIN OUTCOMES MEASURES

Primary outcome measure was maternal risk of preterm delivery by county; primary independent variable was county-level well-being as measured by the Gallup-Sharecare Well-Being Index (WBI).

RESULTS

Women living in counties with higher population well-being had a lower rate of preterm delivery. The rate of preterm birth in counties in the lowest WBI quintile was 13.1%, while the rate of preterm birth in counties in the highest WBI quintile was 10.9%. In the model adjusted for maternal risk factors (age, race, Hispanic ethnicity, smoking status, timing of initiation of prenatal visits, multiparity, maternal insurance payer), the association was slightly attenuated with an absolute difference of 1.9% (95% CI 1.7% to 2.1%; p<0.001).

CONCLUSIONS

Pregnant women who live in areas with higher population well-being have lower risk of preterm birth, even after accounting for individual risk factors.

Giving a good start to a new life via maternal brain allostatic adaptations in pregnancy

Successful pregnancy requires adjustments to multiple maternal homeostatic mechanisms, governed by the maternal brain to support and enable survival of the growing fetus and placenta. Such adjustments fit the concept of allostasis (stability through change) and have a cost: allostatic load. Allostasis is driven by ovarian, anterior pituitary, placental and feto-placental hormones acting on the maternal brain to promote adaptations that support the pregnancy and protect the fetus. Many women carry an existing allostatic load into pregnancy, from socio-economic circumstances, poor mental health and in 'developed' countries, also from obesity. These pregnancies have poorer outcomes indicating negative interactions (failing allostasis) between pre-pregnancy and pregnancy allostatic loads. Use of animal models, such as adult prenatally stressed female offspring with abnormal neuroendocrine, metabolic and behavioural phenotypes, to probe gene expression changes, and epigenetic mechanisms in the maternal brain in adverse pregnancies are discussed, with the prospect of ameliorating poor pregnancy outcomes.

Prenatal stress and child development: A scoping review of research in low- and middle-income countries

INTRODUCTION

Past research has shown relationships between stress during pregnancy, and related psychosocial health measures such as anxiety and depressive symptoms, with infant, child, and adult outcomes. However, most research is from high-income countries. We conducted a scoping review to identify research studies on prenatal stress and outcomes of the pregnancy or offspring in low- and middle-income countries (LMICs), and to synthesize the stress measures and outcomes assessed, the findings observed, and directions for future research.

METHODS

We searched PubMed, Scopus, and PsycINFO for English-language abstracts published from Jan 1960-Jan 2017. Search terms were related to stress and psychosocial health; pregnancy; infant or child development; and LMICs.

RESULTS

48 articles were identified. Sixty percent of studies were in upper-middle, 25% in lower-middle, and 15% in low income countries. Most studies used questionnaires, either existing or tailor-made, to assess stress. Eight assessed cortisol. Most studies (n = 31) assessed infant outcomes at birth, particularly gestational age or preterm birth (n = 22, 12 showing significant relationships), and birthweight (n = 21, 14 showing significant relationships). Five studies analyzed outcomes later in infancy such as temperament and motor development, all showing significant results; and nine in childhood such as behavioral development, asthma, and physical growth, with eight showing significant results.

CONCLUSIONS

Results highlight the importance of prenatal stress on infant and child outcomes in LMICs. Methods used in high-income countries are successfully employed in LMICs, but tailored tools remain necessary. Careful assessment of covariates is needed to foster analyses of interactive effects and pathways. Studies including longer-term follow-up should be prioritized.

Allostatic load: A theoretical model for understanding the relationship between maternal posttraumatic stress disorder and adverse birth outcomes

BACKGROUND

Adverse birth outcomes such as preterm birth and low birth weight are significant public health concerns and contribute to neonatal morbidity and mortality. Studies have increasingly been exploring the predictive effects of maternal posttraumatic stress disorder (PTSD) on adverse birth outcomes. However, the biological mechanisms by which maternal PTSD affects birth outcomes are not well understood. Allostatic load refers to the cumulative dysregulations of the multiple physiological systems as a response to multiple social-ecological levels of chronic stress. Allostatic load has been well documented in relation to both chronic stress and adverse health outcomes in non-pregnant populations. However, the mediating role of allostatic load is less understood when it comes to maternal PTSD and adverse birth outcomes.

OBJECTIVE

To propose a theoretical model that depicts how allostatic load could mediate the impact of maternal PTSD on birth outcomes.

METHOD

We followed the procedures for theory synthesis approach described by Walker and Avant (2011), including specifying focal concepts, identifying related factors and relationships, and constructing an integrated representation. We first present a theoretical overview of the allostatic load theory and the other 4 relevant theoretical models. Then we provide a brief narrative review of literature that empirically supports the propositions of the integrated model. Finally, we describe our theoretical model.

FINDINGS/CONCLUSIONS

The theoretical model synthesized has the potential to advance perinatal research by delineating multiple biomarkers to be used in future. After it is well validated, it could be utilized as the theoretical basis for health care professionals to identify high-risk women by evaluating their experiences of psychosocial and traumatic stress and to develop and evaluate service delivery and clinical interventions that might modify maternal perceptions or experiences of stress and eliminate their impacts on adverse birth outcomes.

Adverse Perinatal Outcomes and Postpartum Multi-Systemic Dysregulation: Adding Vitamin D Deficiency to the Allostatic Load Index

Background Allostatic load (AL) is an index of multi-system physiological "wear-and-tear," operationalizing emergent chronic disease risk and predicting morbidity and mortality. AL has been proposed as an organizing framework for studying pregnancy outcomes and additional AL biomarkers for the study of maternal health would be valuable. Objectives To test whether adverse perinatal outcomes are associated with postpartum AL and if including vitamin D deficiency (serum 25(OH)D < 20 ng/ml) as an additional marker of postpartum AL increases the association. Methods The Community Child Health Network is a community-based participatory research network that enrolled women at birth and followed them for 2 years measuring ten biomarkers (body mass index, waist: hip ratio, pulse, systolic and diastolic blood pressures, cortisol slope, c-reactive protein, hgbA1c, HDL, and total cholesterol) at 6 and 12 months postpartum. A composite of four adverse perinatal outcomes (low birth weight, preterm birth, preeclampsia, and gestational diabetes) was collected from medical charts in a sample of 164 women from one site and serum 25(OH)D status was measured 24-39 weeks postpartum in this cohort. Results Twenty-nine percent experienced one or more of the four adverse perinatal outcomes. Serum 25(OH)D was significantly inversely correlated with the AL index (Spearman's r = -0.247, p = 0.002). Logistic regression results adjusting for maternal age and race showed that adverse outcome was significantly associated with higher postpartum AL (OR 1.53 for a 1-unit increase in AL, 95% CI 1.24-1.89). Adding 25(OH)D deficiency as an 11th component to the AL index improved the model fit (Delta (-2LogL) = 3.955, p = 0.047), and improved the Akaike information criterion (180.32 vs. 184.27). Conclusion Women with adverse perinatal outcomes have higher postpartum AL and adding vitamin D deficiency to the AL index strengthens this association.

The effects of chronic stress on the human brain: From neurotoxicity, to vulnerability, to opportunity

For the last five decades, science has managed to delineate the mechanisms by which stress hormones can impact on the human brain. Receptors for glucocorticoids are found in the hippocampus, amygdala and frontal cortex, three brain regions involved in memory processing and emotional regulation. Studies have shown that chronic exposure to stress is associated with reduced volume of the hippocampus and that chronic stress can modulate volumes of both the amygdala and frontal cortex, suggesting neurotoxic effects of stress hormones on the brain. Yet, other studies report that exposure to early adversity and/or familial/social stressors can increase vulnerability to stress in adulthood. Models have been recently developed to describe the roles that neurotoxic and vulnerability effects can have on the developing brain. These models suggest that developing early stress interventions could potentially counteract the effects of chronic stress on the brain and results going along with this hypothesis are summarized.

An assessment of depression, psychosocial factors, and resilience among women seeking prenatal care at an urban community health center

OBJECTIVE

To describe the relationship between resilience and mental health and psychosocial characteristics in the prenatal period.

METHODS

A prospective cohort pilot study was conducted among English-speaking women aged 18 years or older with singleton pregnancies of at least 20 weeks' duration who received prenatal care at an urban community health center in the USA between March and October 2014. Surveys were administered and a retrospective chart review was conducted. Resilience and depression were measured using validated scales and anxiety was self-reported. Univariate and bivariate analyses were performed.

RESULTS

Thirty women participated. The median resilience score was 82.0 (interquartile range [IQR] 74.0-92.0). Median resilience scores were significantly lower among women with a history of depression (73.0 [IQR 66.0-81.0]) than among those without a history (85.0 [IQR 79.0-92.0]; P=0.007). A history of using medication for anxiety, depression, or insomnia before pregnancy was also associated with lower resilience (median 74.0 [IQR 64.5-80.0] vs 83.5 [IQR 79.0-92.0]; P=0.029). Neither anxiety nor substance use was associated with resilience. Higher resilience was associated with religious affiliation and having adequate financial resources (both P<0.05).

CONCLUSION

Depression history, prior medication use, religious affiliation, and financial security affect resilience in pregnancy. These data inform a strengths-based approach to prenatal care and future research endeavors.

Seeking help for perinatal psychological distress: a meta-synthesis of women's experiences

BACKGROUND

Women may not seek help for perinatal psychological distress, despite regular contact with primary care services. Barriers include ignorance of symptoms, inability to disclose distress, others' attitudes, and cultural expectations. Much of the evidence has been obtained from North American populations and may not, therefore, extrapolate to the UK.

AIM

To understand the factors affecting women's decision to seek help for perinatal distress.

DESIGN AND SETTING

Meta-synthesis of the available published qualitative evidence on UK women's experiences of seeking help for perinatal distress.

METHOD

Systematic searches were conducted in accordance with PRISMA guidelines. Databases searched were PubMed, Scopus, PsycINFO, PsycARTICLES, CINAHL, and Academic Search Complete. Searches of grey literature and references were also conducted. Studies were eligible for inclusion if they reported qualitative data on UK women's experiences of perinatal distress and contact with healthcare professionals. The synthesis was conducted using meta-ethnography.

RESULTS

In all, 24 studies were eligible for inclusion. Metasynthesis identified three main themes: identifying a problem, the influence of healthcare professionals, and stigma. These themes build on current understanding of help seeking by identifying the need for women to be able to frame their experience, for healthcare professionals to educate women about their roles, the need for continuity of care, and the way that being seen as a 'bad mother' causes women to self-silence.

CONCLUSION

Perinatal care provision needs to allow for continuity of care and for staff training that facilitates awareness of factors that influence women's help seeking. Further research is required, particularly in relation to effective means of identifying perinatal psychological distress.

Mentors Offering Maternal Support Reduces Prenatal, Pregnancy-Specific Anxiety in a Sample of Military Women

OBJECTIVE

To determine the efficacy of the Mentors Offering Maternal Support (MOMS) program to reduce pregnancy-specific anxiety and depression and build self-esteem and resilience in military women.

DESIGN

Randomized controlled trial with repeated measures.

SETTING

Large military community in Texas.

PARTICIPANTS

Pregnant women (N = 246) in a military sample defined as active duty or spouse of military personnel.

METHODS

Participants were randomized in the first trimester to the MOMS program or normal prenatal care. Participants attended eight 1-hour sessions every other week during the first, second, and third trimesters of pregnancy. Pregnancy-specific anxiety, depression, self-esteem, and resilience were measured in each trimester. Linear mixed models were used to compare the two-group difference in slope for prenatal anxiety, depression, self-esteem, and resilience.

RESULTS

The Prenatal Self-Evaluation Questionnaire was used to measure perinatal anxiety. Rates of prenatal anxiety on the Identification With a Motherhood Role (p = .049) scale and the Preparation for Labor (p = .017) scale were significantly reduced for participants in MOMS. Nulliparous participants showed significantly lower anxiety on the Acceptance of Pregnancy scale and significantly greater anxiety on the Preparation for Labor scale. Single participants had significantly greater anxiety on the Well-Being of Self and Baby in Labor scale, and participants with deployed husbands had significantly greater anxiety on the Identification With a Motherhood Role scale.

CONCLUSION

Participation in the MOMS program reduced pregnancy-specific prenatal anxiety for the dimensions of Identification With a Motherhood Role and Preparation for Labor. Both dimensions of anxiety were previously found to be significantly associated with preterm birth and low birth weight. Military leaders have recognized the urgent need to support military families.

Explaining racial and ethnic inequalities in postpartum allostatic load: Results from a multisite study of low to middle income woment

BACKGROUND

Racial and ethnic inequalities in women's health are widely documented, but not for the postpartum period, and few studies examine whether neighborhood, psychosocial, and biological factors explain these gaps in women's health.

METHODS

Using prospective longitudinal data collected from 1766 low to middle income women between 2008 and 2012 by the Community Child Health Network (CCHN), we tested the extent to which adjustment for neighborhood, economic, psychological, and medical conditions following a birth explained differences between African American, Latina, and White women in an indicator of physiological dysregulation allostatic load (AL), at one year postpartum as measured by 10 biomarkers: Body Mass Index, Waist Hip Ratio, systolic and diastolic blood pressure, high sensitivity C-reactive protein, Hemoglobin A1c, high-density lipoprotein and cholesterol ratio, and diurnal cortisol.

RESULTS

Mean postpartum AL scores were 4.65 for African American, 4.57 for Latina and 3.86 for White women. Unadjusted regression estimates for high AL for African American women (with White as the reference) were 0.80 (SD = 0.11) and 0.53 (SD = 0.15) for Latina women. Adjustment for household poverty, neighborhood, stress, and resilience variables resulted in a reduction of 36% of the excess risk in high AL for African Americans versus Whites and 42% of the excess risk for Latinas compared to Whites.

CONCLUSIONS

Racial and ethnic inequalities in AL were accounted for largely by household poverty with additional contributions by psychological, economic, neighbourhood and medical variables. There remained a significant inequality between African American, and Latina women as compared to Whites even after adjustment for this set of variables. Future research into health inequalities among women should include a fuller consideration of the social determinants of health including employment, housing and prepregnancy medical conditions.

Maternal and pediatric health and disease: integrating biopsychosocial models and epigenetics

The concepts of allostasis (stability through adaptation) and accumulated life stress (McEwen's allostatic load) aim to understand childhood and adult outcomes. Chronic malnutrition, changes in social condition, and adverse early-life experiences may program phenotypes and contribute to long-lasting disease risk. However, integration of life course approaches, social and economic contexts, and comparison among different biopsychosocial models has not generally been explored. This review critically examines the literature and evaluates recent insights into how environmental stress can alter lifelong hypothalamic-pituitary-adrenal axis and immune system responsiveness and induce metabolic and neurodevelopmental maladaptation. Models of biopsychosocial stress overlap but may consider different conditions. Concepts include allostasis, which incorporates hormonal responses to predictable environmental changes, and Geronimus's "weathering," which aims to explain how socially structured, repeated stress can accumulate and increase disease vulnerability. Weathering emphasizes roles of internalized/interpersonal racism in outcomes disparities. For Mexican immigrants and Mexican Americans, the "acculturation" framework has proven especially useful to explore disparities, including preterm birth and neuropsychiatric risks in childhood. Complexities of stress assessments and recent research into epigenetic mechanisms mediating effects of physical, nutritional, psychological, and social stress are reviewed.

Antenatal depression is associated with pregnancy-related anxiety, partner relations, and wealth in women in Northern Tanzania: a cross-sectional study

Background

Psychosocial health problems, specifically depression during pregnancy, can have negative impact on birth outcomes, postnatal mental health of the mother, and infant health. Antenatal depression is more prevalent among women in low- and middle-income countries than among women in high-income countries. Risk factors for antenatal depression reported in the literature relate to pregnant women in South Asia. Consequently, this study assessed depression in pregnancy and related psychosocial risk factors among select pregnant women residing in Mwanza region, Northern Tanzania.

Methods

We analysed data from 397 pregnant women recruited from three antenatal clinics for the period June—August 2013 for this cross-sectional study. Women provided data at one time point during their pregnancy by completing the Edinburgh Postnatal Depression Scale and a structured questionnaire assessing psychosocial, demographic, and behavioural risk factors related to antenatal depression. Multiple logistic regression analysis was performed to determine the relationship between risk factors examined and antenatal depression.

Results

Overall, 33.8 % (n = 134) of pregnant women had antenatal depression. Pregnancy-related anxiety was associated with antenatal depression (odds ratio (OR) 1.36, 95 % confidence interval (CI) 1.23 to 1.5). Pregnant women with poor relationship with partner and low/moderate socio-economic status had the highest OR for antenatal depression (82.34, 95 % CI 4.47, 1516.60) after adjusting for other covariates. Pregnant women with poor relationship with partner and high socio-economic status had an OR of 13.48 (95 % CI 1.71, 106.31) for antenatal depression. “Reference” pregnant women were those with very good relationship with partner and high socio-economic status.

Conclusions

High proportion of self-reported depression among select pregnant women attending antenatal clinics in Mwanza, Tanzania merit integrating depression assessment into existing antenatal care services. Health care providers need to assess pregnancy-related risk factors (pregnancy-related anxiety), socio-demographic factors (socio-economic status), and interpersonal risk factors (relationship with partner). Future research should appraise effectiveness of interventions that enhance partner relationships in reducing antenatal depression across all wealth distributions.

Psychobiobehavioral Model for Preterm Birth in Pregnant Women in Low- and Middle-Income Countries

Preterm birth (PTB) is a final common outcome resulting from many interrelated etiological pathways; of particular interest is antenatal psychosocial distress (i.e., stress, anxiety, and depression). In LMI countries, both exposure to severe life stressors and rate of PTB are on average greater when compared with high-income countries. In LMI countries women are exposed to some of the most extreme psychosocial stress worldwide (e.g., absolute poverty, limited social resources). High prevalence of antenatal stress and depression have been observed in some studies from LMI countries. We propose a psychosocial, biological, and behavioral model for investigating the complex multisystem interactions in stress responses leading to PTB and explain the basis of this approach. We discuss ethical considerations for a psychosocial, biological, and behavioral screening tool to predict PTB from a LMI country perspective.

Disparities and relative risk ratio of preterm birth in six Central and Eastern European centers

AIM

To identify characteristic risk factors of preterm birth in Central and Eastern Europe and explore the differences from other developed countries.

METHOD

Data on 33,794 term and 3867 preterm births (<37 wks.) were extracted in a retrospective study between January 1, 2007 and December 31, 2009. The study took place in 6 centers in 5 countries: Czech Republic, Hungary (two centers), Romania, Slovakia, and Ukraine. Data on historical risk factors, pregnancy complications, and special testing were gathered. Preterm birth frequencies and relevant risk factors were analyzed using Statistical Analysis System (SAS) software.

RESULTS

All the factors selected for study (history of smoking, diabetes, chronic hypertension, current diabetes, preeclampsia, progesterone use, current smoking, body mass index, iron use and anemia during pregnancy), except the history of diabetes were predictive of preterm birth across all participating European centers. Preterm birth was at least 2.4 times more likely with smoking (history or current), three times more likely with preeclampsia, 2.9 times more likely with hypertension after adjusting for other covariates. It had inverse relationship with the significant predictor body mass index, with adjusted risk ratio of 0.8 to 1.0 in three sites. Iron use and anemia, though significant predictors of preterm birth, indicated mixed patterns for relative risk ratio.

CONCLUSION

Smoking, preeclampsia, hypertension and body mass index seem to be the foremost risk factors of preterm birth. Implications of these factors could be beneficial for design and implementation of interventions and improve the birth outcome.

Early adversity, immunity and infectious disease

Complex interactions between biological, behavioral and environmental factors are involved in mediating individual differences in health and disease. In this review, we present evidence suggesting that increased vulnerability to infectious disease may be at least, in part, due to long-lasting effects of early life psychosocial adversities. Studies have shown that maternal psychosocial stress during pregnancy is associated with long lasting changes in immune function and disease resistance in the offspring. Studies further indicated that harsh environmental conditions during the neonatal period may also cause lasting changes in host response to infectious disease. Although the mechanisms involved in these effects have not been fully examined, several potential mediators have been described, including changes in the development of the offspring hypothalamic-pituitary-adrenal axis, alterations in epigenetic pathways, stress-related maternal health risk behavior and infection during pregnancy. Although there are ample literature indicating that perinatal psychosocial stress increases vulnerability to disease, other reports suggest that mild predictable stressors may benefit the organism and allow better coping with future stressors. Thus, understanding the possible consequences of perinatal adversities and the mechanisms that are involved in immune regulation is important for increasing awareness to the potential outcomes of early negative life events and providing insight into potential therapies to combat infection in vulnerable individuals.

Mobile health in maternal and newborn care: fuzzy logic

Whether mHealth improves maternal and newborn health outcomes remains uncertain as the response is perhaps not true or false but lies somewhere in between when considering unintended harmful consequences. Fuzzy logic, a mathematical approach to computing, extends the traditional binary “true or false” (one or zero) to exemplify this notion of partial truths that lies between completely true and false. The commentary explores health, socio-ecological and environmental consequences–positive, neutral or negative. Of particular significance is the negative influence of mHealth on maternal care-behaviors, which can increase stress reactivity and vulnerability to stress-induced illness across the lifespan of the child and establish pathways for intergenerational transmission of behaviors. A mHealth “fingerprinting” approach is essential to monitor psychosocial, economic, cultural, environmental and physical impact of mHealth intervention and make evidence-informed decision(s) about use of mHealth in maternal and newborn care.
