A meta-analysis of depression during pregnancy and the risk of preterm birth, low birth weight, and intrauterine growth restriction

Timing of selective serotonin reuptake inhibitor use and risk for preterm birth and related adverse events: with a consideration of the COVID-19 pandemic period

OBJECTIVE

There is uncertainty around the safety of SSRIs for treating depression during pregnancy. Nevertheless, the use of SSRIs has been gradually increasing, especially during the COVID-19 pandemic period. We aimed to (1) characterize maternal depression rate and use of SSRIs in a recent 10-year period, (2) address confounding by indication, as well as socioeconomic and environmental factors, and (3) evaluate associations of the timing of SSRI exposure in pregnancy with risk for preterm birth (PTB), low birthweight (LBW), and small for gestational age (SGA) infants among women with depression before pregnancy.

METHODS

We conducted propensity score-adjusted regression to calculate odds ratios (ORs) of PTB, LBW, and SGA. We accounted for maternal/pregnancy characteristics, comorbidity, depression severity, time of delivery, social vulnerability, and rural residence.

RESULTS

There were 50.3% and 40.3% increases in the prevalence rate of prenatal depression and prenatal SSRI prescription rate during the pandemic. We identified women with depression ≤180 days before pregnancy (n = 8406). Women with no SSRI order during pregnancy (n = 3760) constituted the unexposed group. The late SSRI exposure group consisted of women with an SSRI order after the first trimester (n = 3759). The early-only SSRI exposure group consisted of women with SSRI orders only in the first trimester (n = 887). The late SSRI exposure group had an increased risk of PTB of OR = 1.5 ([1.2,1.8]) and LBW of OR = 1.5 ([1.2,2.0]), relative to the unexposed group. Associations between late SSRI exposure and risk of PTB/LBW were similar among a subsample of patients who delivered during the pandemic.

CONCLUSIONS

These findings suggest an association between PTB/LBW and SSRI exposure is dependent on exposure timing during pregnancy. Small for gestational age is not associated with SSRI exposure.

What Do Your Neighbors Think About You? How Perceived Neighbor Attitudes Toward Latinos Influence Mental Health Among a Pregnant Latina Cohort

Latina women living in the USA experience disproportionately higher rates of psychological distress compared to their non-Latina White counterparts. Poor maternal mental health during pregnancy can contribute to intergenerational mental health disparities. Through this pathway, mothers' experiences, environments, and exposures (henceforth "exposures") during pregnancy become biologically embodied and can negatively affect the fetus and life-long developmental trajectories of her child. One of the exposures that can affect mother-offspring dyads is the neighborhood. With the goal of integrating anthropological and sociological theories to explain mental health disparities among pregnant Latina women, we explored how perceptions of neighbor attitudes may influence mental health during pregnancy. We analyzed self-reported responses from 239 pregnant Latina women in Southern California (131 foreign-born, 108 US-born) on their mental health and perceived attitudes of their neighbors using multiple linear regression models. Among foreign-born Latina women, living in neighborhoods with more favorable views of Latinos was associated with lower depression scores (pooled β =  - .70, SE = .29, p = .019) and lower pregnancy-related anxiety scores (pooled β =  - .11, SE = .05, p = .021), but greater state anxiety scores (pooled β = .09, SE = .04, p = .021). Among US-born women, there were no associations between neighbor attitudes and mental health. Overall, results suggest that social environments are correlated with mental health and that foreign-born and US-born Latinas have varied mental health experiences in the USA. Our findings highlight the importance of improving aspects of neighborhood cohesion as part of maternal-fetal care management.

Dietary Intake of Nutrients Involved in Serotonin and Melatonin Synthesis and Prenatal Maternal Sleep Quality and Affective Symptoms

Poor sleep quality and psychological distress in pregnancy are important health concerns. Serotonin and melatonin levels may underlie variation in these adverse outcomes. In this study, we examined dietary nutrients involved in serotonin and melatonin synthesis in relation to maternal sleep quality and affective symptoms during pregnancy. Pregnant women at no greater than normal medical risk at enrollment completed 24-hour dietary recalls in mid-late pregnancy. Usual intakes of vitamin B6, vitamin D, eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA), and tryptophan were estimated from dietary intake of foods and supplements using the National Cancer Institute (NCI) method. Sleep quality, depression, and anxiety were measured using validated questionnaires. Associations between nutrient intakes, sleep quality, and affective symptoms were estimated using generalized estimating equation models adjusting for potential confounding factors. In minimally adjusted models, EPA + DHA and tryptophan intakes were associated with a lower score indicating better sleep quality (b: -1.07, 95% CI: -2.09, -0.05) and (b: -12.40, 95% CI: -24.60, -0.21), respectively. EPA + DHA and tryptophan intakes were also associated with a lower odds of shorter sleep duration and sleep disturbances. In addition, tryptophan was associated with a lower odds of higher sleep latency. However, associations were attenuated and nonsignificant after adjustment for demographic and lifestyle factors. In conclusion, intakes of EPA + DHA and tryptophan were associated with improved sleep quality, but these associations were confounded by maternal demographic and lifestyle characteristics. This study highlights the need to consider dietary intake and pregnancy health in the context of demographic characteristics and lifestyle behaviors.

Black Pregnant and Postpartum Peoples' Perspectives on Mental Health and Substance Use Disorders

Introduction: Mental health and substance use disorders in pregnant and postpartum people (PPP) are common, and most will not receive adequate treatment. In addition, Black PPP experience higher rates of mental health conditions and are less likely to receive treatment compared with White PPP. Yet, our understanding of the experience of Black PPP with respect to these conditions is limited. The goal of this study was to better understand these experiences with respect to mental health, substance use, and barriers to treatment. Methods: Semi-structured interviews were completed with 68 Black PPP who were pregnant or had been pregnant in the last 24 months to gain an understanding of mental health and substance use screening and treatment during the peripartum and postpartum period. Interview data were analyzed with qualitative software, using a qualitative content analysis method, informed by grounded theory. Results: Four main themes were identified: (1) personal beliefs and views about mental health and substance use, (2) family and community beliefs about mental health and substance use, (3) personal experience with mental health and substance use, and (4) comfort in talking to others about mental health and substance use. Subthemes evolved within each of the four themes. Black PPP indicated that maternal mental health and substance use disorders are common in the Black community, but negative stigma related to these conditions often prevents PPP from talking about these conditions or seeking support or treatment despite believing that support and treatment can be beneficial. Conclusions: Clinical practice initiatives within this population can focus on advanced training for providers to more clearly understand personal experiences and related stigma related to mental health and substance use disorders, with the goal of supporting Black PPP mental health needs.

Improvements in Maternal Cardiovascular Health Over the Perinatal Period Longitudinally Predict Lower Postpartum Psychological Distress Among Individuals Who Began Their Pregnancies With Overweight or Obesity

BACKGROUND

Adverse cardiovascular events during pregnancy (eg, preeclampsia) occur at higher rates among individuals with overweight or obesity (body mass index ≥25 kg/m2) and have been associated with postpartum depression. The present study examined whether changes in cardiovascular health (CVH) during the perinatal period, as defined by the American Heart Association's Life's Essential 8 framework, predicted postpartum psychological functioning among individuals with prepregnancy body mass index ≥25 kg/m2.

METHODS AND RESULTS

Pregnant individuals (N = 226; mean ± SD age = 28.43 ± 5.4 years; mean body mass index = 34.17 ± 7.15 kg/m2) were recruited at 12 to 20 weeks of gestation (mean, 15.64 ± 2.45 weeks) for a longitudinal study of health and well-being. Participants completed ratings of depression and perceived stress and reported on CVH behaviors (dietary intake, physical activity, nicotine exposure, and sleep) at baseline and at 6 months postpartum. Body mass index and CVH behaviors were used to calculate a composite CVH score at both time points. Linear regression analyses were performed to examine whether change in CVH related to postpartum symptom scores. Because sleep was measured in only a subset of participants (n = 114), analyses were conducted with and without sleep. Improved CVH was associated with lower postpartum depression (β = -0.18, P<0.01) and perceived stress (β = -0.13, P=0.02) scores. However, when including sleep, these relationships were no longer significant (all P>0.4).

CONCLUSIONS

Improvements in CVH from early pregnancy to 6 months postpartum were associated with lower postpartum depressive symptoms and perceived stress but not when including sleep in the CVH metric, potentially due to the large reduction in sample size. These data suggest that intervening during pregnancy to promote CVH may improve postpartum psychological functioning among high-risk individuals.

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

BACKGROUND

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

METHODS

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

RESULTS

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

LIMITATION

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

CONCLUSION

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

Efficacy and safety of a mineral and vitamin treatment on symptoms of antenatal depression: 12-week fully blinded randomised placebo-controlled trial (NUTRIMUM)

BACKGROUND

Broad-spectrum micronutrients (minerals and vitamins) have shown benefit for treatment of depressive symptoms.

AIMS

To determine whether additional micronutrients reduce symptoms of antenatal depression.

METHOD

Eighty-eight medication-free pregnant women at 12-24 weeks gestation, who scored ≥13 on the Edinburgh Postnatal Depression Scale (EPDS), were randomised 1:1 to micronutrients or active placebo (containing iodine and riboflavin), for 12 weeks. Micronutrient doses were generally between recommended dietary allowance and tolerable upper level. Primary outcomes (EPDS and Clinical Global Impression - Improvement Scale (CGI-I)) were analysed with constrained longitudinal data analysis.

RESULTS

Seventeen (19%) women dropped out, with no group differences, and four (4.5%) gave birth before trial completion. Both groups improved on the EPDS, with no group differences (P = 0.1018); 77.3% taking micronutrients and 72.7% taking placebos were considered recovered. However, the micronutrient group demonstrated significantly greater improvement, based on CGI-I clinician ratings, over time (P = 0.0196). The micronutrient group had significantly greater improvement on sleep and global assessment of functioning, and were more likely to identify themselves as 'much' to 'very much' improved (68.8%) compared with placebo (38.5%) (odds ratio 3.52, P = 0.011; number needed to treat: 3). There were no significant group differences on treatment-emergent adverse events, including suicidal ideation. Homocysteine decreased significantly more in the micronutrient group. Presence of personality difficulties, history of psychiatric medication use and higher social support tended to increase micronutrient response compared with placebo.

CONCLUSIONS

This study highlights the benefits of active monitoring on antenatal depression, with added efficacy for overall functioning when taking micronutrients, with no evidence of harm. Trial replication with larger samples and clinically diagnosed depression are needed.

Impact of miscarriage and termination of pregnancy on subsequent pregnancies: A longitudinal study of maternal and paternal depression, anxiety and eudaimonia

BACKGROUND

Although miscarriage and termination of pregnancy affect maternal mental illnesses on subsequent pregnancies, their effects on the positive mental health (e.g., eudaimonia) of both first-time and multi-time parents have received minimal attention, especially for fathers. This longitudinal study examines the effects of experiences of miscarriage and termination on parental well-being in subsequent pregnancies from prenatal to postpartum years, while simultaneously considering parity.

METHODS

Pregnant women and their partners were recruited during early prenatal visits in Taiwan from 2011 to 2022 and were followed up from mid-pregnancy to 1 year postpartum. Six waves of self-reported assessments were employed.

RESULTS

Of 1813 women, 11.3 % and 14.7 % had experiences of miscarriage and termination, respectively. Compared with the group without experiences of miscarriage or termination, experiences of miscarriage were associated with increased risks of paternal depression (adjusted odds ratio = 1.6, 95 % confidence interval [CI] = 1.13-2.27), higher levels of anxiety (adjusted β = 1.83, 95 % CI = 0.21-3.46), and lower eudaimonia scores (adjusted β = -1.09, 95 % CI = -1.99 to -0.19) from the prenatal to postpartum years, particularly among multiparous individuals. Additionally, experiences of termination were associated with increased risks of depression in their partner.

LIMITATIONS

The experiences of miscarriage and TOP were self-reported and limited in acquiring more detailed information through questioning.

CONCLUSIONS

These findings highlight the decreased well-being of men whose partners have undergone termination of pregnancy or experienced miscarriage, and stress the importance of interventions aimed at preventing adverse consequences among these individuals.

Risk factors and predictive model for prenatal depression: A large retrospective study in China

BACKGROUND

Prenatal depression, associated with adverse effects on mothers and fetuses, has received little attention. We conducted a large-sample study to investigate the risk factors of, and develop a predictive model for, prenatal depression in the Chinese population.

METHODS

This study enrolled 14,329 pregnant women who delivered at the West China Second University Hospital, Sichuan University from January 2017 to December 2020. Participants were divided into a training or validation cohort. Multiple variables were collected and selected using univariate logistic regression and least absolute shrinkage and selection operator penalty regression. After multivariate logistic analysis, a predictive model was developed and validated internally and externally.

RESULTS

Nine variables (employment, planned pregnancy, pregnancy number, conception methods, gestational diabetes mellitus, twin pregnancy, placenta previa, umbilical cord encirclement, and educational attainment) were identified as independent risk factors for prenatal depression. Receiver operating characteristic curves in both the training and validation cohorts showed excellent discrimination of the predictive model (the area under the curve: 0.746 and 0.732, respectively).

LIMITATIONS

The results of this retrospective study may be affected by confounding and information bias. Some important variables were excluded, such as family history of mental disorders. The study was conducted in China; its results may not be generalizable to other regions.

CONCLUSION

Our study identified nine significant risk factors for prenatal depression and constructed an accurate predictive model. This model could be applied as a clinical decision aid for individualized risk estimates and prevention of prenatal depression.

Discrimination and perinatal depressive symptoms: The protective role of social support and resilience

BACKGROUND

Discrimination is an important social determinant of perinatal depression; however, evidence is limited regarding modifiable social and psychological factors that may moderate this association. We examined whether social support and resilience could protect against the adverse effects of discrimination on perinatal depressive symptoms.

METHODS

Pregnant people (N = 589) receiving Expect With Me group prenatal care in Nashville, TN and Detroit, MI completed surveys during third trimester of pregnancy and six months postpartum. Linear regression models tested the association between discrimination and depressive symptoms, and the moderating effects of social support and resilience, during pregnancy and postpartum.

RESULTS

The sample was predominantly Black (60.6 %), Hispanic (15.8 %) and publicly insured (71 %). In multivariable analyses, discrimination was positively associated with depressive symptoms during pregnancy (B = 4.44, SE = 0.37, p ≤0.001) and postpartum (B = 3.78, SE = 0.36, p < 0.001). Higher social support and resilience were associated with less depressive symptoms during pregnancy (B = -0.49, SE = 0.08, p < 0.001 and B = -0.67, SE = 0.10, p < 0.001, respectively) and postpartum (B = -0.32, SE = 0.07, p < 0.001 and B = -0.56, SE = 0.08, p < 0.001, respectively). Social support was protective against discrimination (pregnancy interaction B = -0.23, SE = 0.09, p = 0.011; postpartum interaction B = -0.35, SE = 0.07, p < 0.001). There was no interaction between discrimination and resilience at either time.

LIMITATIONS

The study relied on self-reported measures and only included pregnant people who received group prenatal care in two urban regions, limiting generalizability.

CONCLUSIONS

Social support and resilience may protect against perinatal depressive symptoms. Social support may also buffer the adverse effects of discrimination on perinatal depressive symptoms, particularly during the postpartum period.

Impact of prenatal maternal depression on gestational length: post hoc analysis of a randomized clinical trial

Background

Shortened gestation is a leading cause of childhood morbidity and mortality with lifelong consequences for health. There is a need for public health initiatives on increasing gestational age at birth. Prenatal maternal depression is a pervasive health problem robustly linked via correlational and epidemiological studies to shortened gestational length. This proof-of-concept study tests the impact of reducing prenatal maternal depression on gestational length with analysis of a randomized clinical trial (RCT).

Methods

Participants included 226 pregnant individuals enrolled into an RCT and assigned to receive either interpersonal psychotherapy (IPT) or enhanced usual care (EUC). Recruitment began in July 2017 and participants were enrolled August 10, 2017 to September, 8 2021. Depression diagnosis (Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition; DSM 5) and symptoms (Edinburgh Postnatal Depression Scale and Symptom Checklist) were evaluated at baseline and longitudinally throughout gestation to characterize depression trajectories. Gestational dating was collected based on current guidelines via medical records. The primary outcome was gestational age at birth measured dichotomously (≥39 gestational weeks) and the secondary outcome was gestational age at birth measured continuously. Posthoc analyses were performed to test the effect of reducing prenatal maternal depression on gestational length. This trial is registered with ClinicalTrials.gov (NCT03011801).

Findings

Steeper decreases in depression trajectories across gestation predicted later gestational age at birth, specifically an increase in the number of full-term babies born ≥39 gestational weeks (EPDS linear slopes: OR = 1.54, 95% CI 1.10-2.16; and SCL-20 linear slopes: OR = 1.67, 95% CI 1.16-2.42). Causal mediation analyses supported the hypothesis that participants assigned to IPT experienced greater reductions in depression symptom trajectories, which in turn, contributed to longer gestation. Supporting mediation, the natural indirect effect (NIE) showed that reduced depression trajectories resulting from intervention were associated with birth ≥39 gestational weeks (EPDS, OR = 1.65, 95% CI 1.02-2.66; SCL-20, OR = 1.85, 95% CI 1.16-2.97).

Interpretation

We used a RCT design and found that reducing maternal depression across pregnancy was associated with lengthened gestation.

Funding

This research was supported by the NIH (R01 HL155744, R01 MH109662, R21 MH124026, P50 MH096889).

Midwifery continuity of care for women with perinatal mental health conditions: A cohort study from Australia

BACKGROUND

Perinatal mental health (PMH) conditions are associated with adverse outcomes such as maternal suicide, preterm birth and longer-term childhood sequelae. Midwifery continuity of care (one midwife or a small group of midwives) has demonstrated benefits for women and newborns, including a reduction in preterm birth and improvements in maternal anxiety/worry and depression.

AIM

To determine if midwifery care provided through a Midwifery Group Caseload Practice model is associated with improved perinatal outcomes for women who have anxiety and depression and/or other perinatal mental health conditions. An EPDS ≥ 13, and/or answered the thought of harming myself has occurred to me and/or women who self-reported a history compared to standard models of care (mixed midwife/obstetric fragmented care).

METHODS

A retrospective cohort study using data routinely collected via an electronic database between 1 January 2018 31st of January 2021. The population were women with current/history of PMH, who received Midwifery Caseload Group Practice (MCP), or standard care (SC). Data were analysed using descriptive statistics for maternal characteristics and logistic regression for birth outcomes. One-to-one matching of the MCP group with the SC group was based on propensity scores.

RESULTS

7,359 births were included MCP 12% and SC 88%. Anxiety was the most common PMH with the same proportion affected in MCP and SC. Adjusted odds of preterm birth and adverse perinatal outcomes were lower in the MCP group than the SC group (aOR (95%CI): 0.77 (0.55, 1.08) and 0.81 (0.68, 0.97), respectively) and higher for vaginal birth and full breastfeeding (aOR (95% CI): 1.87 (1.60, 2.18) and 2.06 (1.61, 2.63), respectively). In the matched sample the estimate of a relationship between MCP and preterm birth (aOR (95% CI): 0.88 (0.56, 1.42), adverse perinatal outcomes (aOR (95% CI): 0.83 (0.67, 1.05)) and breastfeeding at discharge (aOR (95% CI): 1.82 (1.30, 2.51)), stronger for vaginal birth (aOR (95% CI): 2.22 (1.77, 2.71)).

CONCLUSION

This study supports positive associations between MCP and breastfeeding and vaginal birth. MCP was also associated with lower risk of adverse perinatal outcomes, though in the matched sample with a smaller sample size, the confidence interval included 1. The direction of the association MCP and preterm birth was negative (protective). However, in the matched sample analysis, the confidence interval was wide, and the finding was also consistent with no benefit from MCP. Randomised controlled trials are required to answer questions around preterm birth and adverse perinatal outcomes and further research is being planned.

Antenatal depression among pregnant mothers in Afghanistan: A cross-sectional study

BACKGROUND

Approximately one in five pregnant women experience antenatal depression globally. The purpose of the present study was to estimate the prevalence of antenatal depression and explore its relationship between various demographic variables, recent sexual engagement, and recent adverse life events among pregnant Afghan women.

METHODS

A cross-sectional survey study was carried out between January, 2023 and April 2023 among 460 women aged 15-45 years who were recruited using convenience sampling from Herat province (Afghanistan). Logistic regression models were utilized to explore the relationship between antenatal depression and socio-demographic characteristics among the participants.

RESULTS

The prevalence of antenatal depression symptoms was 78.5%. Multiple regression analysis indicated that antenatal depression was significantly associated with (i) being aged 30-45 years (AOR: 4.216, 95% CI: 1.868-9.515, p = .001), (ii) being of low economic status (AOR:2.102, 95% CI: 1.051-4.202, p = .036), (iii) not being employed (AOR: 2.445, 95% CI:1.189-5.025, p = .015), (iv) not having had sex during the past seven days (AOR: 2.335, 95% CI: 1.427-3.822, p = .001), and (v) not experiencing a traumatic event during the past month (AOR:0.263, 95% CI: 0.139-0.495, p < .001).

CONCLUSION

The present study provides insight into the factors associated with the high prevalence of antenatal depression among pregnant Afghan women (e.g., demographic variables, recent adverse life events, and recent sexual engagement). It highlights the urgency of addressing antenatal depression in Afghanistan and provides a foundation for future research and interventions aimed at improving the mental health and well-being of pregnant women in the Afghan context.

Antenatal depressive symptoms and adverse birth outcomes in healthy start participants: The modifying role of utilization of mental health services

OBJECTIVE

We examined the association between antenatal depressive symptoms and adverse birth outcomes in Midland Healthy Start (MHS) participants and determined whether receiving mental health services reduced the odds of adverse outcomes among those with elevated antenatal depressive symptoms.

METHOD

Data from a retrospective cohort of participants (N = 1,733) served by the MHS in South Carolina (2010-2019) were linked with their birth certificates. A score of ≥16 on the Center for Epidemiologic Studies Depression Scale was defined as elevated antenatal depressive symptoms. Services provided by MHS were categorized into: (1) receiving mental health services, (2) receiving other services, and (3) not receiving any services. Adverse birth outcomes included preterm birth, low birth weight, and small for gestational age.

RESULTS

Around 31 % had elevated antenatal depressive symptoms. The prevalences of preterm birth, low birthweight, and small for gestational age were 9.5 %, 9.1 %, and 14.6 %, respectively. No significant associations were observed between elevated depressive symptoms and adverse outcomes. Among women with elevated antenatal depressive symptoms, the odds for small for gestational age were lower in those who received mental health services (AOR 0.33, 95 % CI 0.15-0.72) or other services (AOR 0.34, 95 % CI 0.16-0.74) compared to those who did not receive any services. The odds for low birth weight (AOR 0.34, 95 % CI 0.13-0.93) were also lower in those who received mental health services.

CONCLUSIONS

Receiving screening and referral services for antenatal depression reduced the risks of having small for gestational age or low birth weight babies among MHS participants.

Disparities in Utilization and Delivery Outcomes for Women with Perinatal Mood and Anxiety Disorders

Perinatal mood and anxiety disorders (PMAD), which include depression and/or anxiety in the year before and/or after delivery, are common complications of pregnancy, affecting up to one in four perinatal individuals, with costs of over $15 billion per year in the US. In this paper, we provide an overview of the disparities in utilization and delivery outcomes for individuals with perinatal mood and anxiety disorders in the US. In addition, we discuss the current US screening and treatment guidelines as well as the high societal costs of illness of PMAD for both perinatal individuals and children. Finally, we outline opportunities for quality improvement of PMAD care in the US, including leveraging increased engagement with healthcare system during prenatal care, working toward a more cohesive national strategy to address PMAD, leaning into evidence-based policymaking through collaboration with a panel of experts, and generating state-level profiles focused on PMAD.

"It is not all glowing and kale smoothies": An exploration of mental health difficulties during pregnancy through women's voices

OBJECTIVES

This study aimed to explore the experiences of women with moderate-to-severe mental health difficulties during pregnancy, with a focus on establishing their psychological needs. Psychological distress caused by mental health difficulties during pregnancy is common and can significantly impact women and their babies. However, women's subjective experiences of difficulties with their mental health throughout pregnancy, alongside their experiences of staff, services and treatments are less well understood.

DESIGN

In this qualitative study, an Interpretive Phenomenological Analysis (IPA) approach was used.

METHODS

Semi-structured interviews were conducted with participants recruited via a regional Perinatal Mental Health Service. Interviews were transcribed and analysed following the IPA methodology.

RESULTS

Five superordinate themes were identified which represented the lived experiences of the 11 participants on their journey through pregnancy whilst living with mental health difficulties and subsequent psychological distress: (i) Feeling the 'wrong' feelings, (ii) Societal pressures and a desire for greater acceptance, (iii) Searching for answers despite a lack of resources, (iv) What made a difference and (v) Experiences and expectations of service provision. Within these themes, 13 subordinate themes were also identified.

CONCLUSIONS

These themes highlight the need for greater awareness and acceptance of mental health difficulties during pregnancy as well as postnatally. While perinatal mental health services are evolving, there is still an urgent requirement for services to continue to develop to meet women's needs, as well as to develop the role of clinicians as facilitators of engagement with needs-matched care.

The Association Between Pre-Pregnancy and First-Trimester Hair Cortisol and Preterm Birth: A Causal Inference Model

Background Adverse life events and chronic psychological distress before and during pregnancy have frequently been associated with preterm birth (PTB) but the biological underpinnings remain unclear. We investigated the association between corticosteroid levels in pre-pregnancy and first-trimester hair and the risk of PTB. Methods We followed 1,808 pregnant women from a prospective pre-birth cohort study in Lima, Perú. Hair samples were taken at the end of the first pregnancy trimester. The two most proximal 3cm segments to the scalp (representing pre-pregnancy and first-trimester) were analyzed to obtain hair cortisol and cortisone concentrations (HCC and HCNC). PTB was defined as birth < 37 completed gestational weeks. We constructed four generalized propensity scores for pre-pregnancy and first-trimester HCC and HCNC to create corresponding inverse probability weights before fitting marginal structural models for estimating the effect of HCC and HCNC on PTB risk. Results Pre-pregnancy Log HCC was not independently associated with PTB risk (RR = 0.97; 95%CI: 0.79, 1.19). In contrast, one SD increase from the mean first-trimester Log HCC was independently associated with a 37% (95%CI: 1.11, 1.69) increased risk of PTB. Although imprecise, pre-pregnancy Log HCNC was negatively associated with PTB risk (RR = 0.84; 95%CI: 0.58, 1.20), whereas the association between first-trimester Log HCNC and PTB risk was positive (RR = 1.20; 95%CI: 0.87, 1.65). Conclusions Our findings show that chronic corticosteroid levels in early pregnancy are causally linked to PTB risk in pregnant Peruvian women. This finding contributes to understanding the biological underpinnings of PTB better to enhance PTB prevention.

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

BACKGROUND

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

AIM

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

METHODS

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

RESULTS

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

CONCLUSION

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

Affective Symptoms in Pregnancy are Associated with the Vaginal Microbiome

Composition of the vaginal microbiome in pregnancy is associated with adverse maternal, obstetric, and child health outcomes. Identifying the sources of individual differences in the vaginal microbiome is therefore of considerable clinical and public health interest. The current study tested the hypothesis that vaginal microbiome composition during pregnancy is associated with an individual's experience of affective symptoms and stress exposure. Data were based on a prospective longitudinal study of a diverse and medically healthy community sample of 275 mother-infant pairs. Affective symptoms and stress exposure and select measures of associated biomarkers (diurnal salivary cortisol, serum measures of sex hormones) were collected at each trimester; self-report, clinical, and medical records were used to collect detailed data on socio-demographic factors and health behavior, including diet and sleep. Vaginal microbiome samples were collected in the third trimester (34-40 weeks) and characterized by 16S rRNA sequencing. Identified taxa were clustered into three community state types (CST1-3) based on dissimilarity of vaginal microbiota composition. Results indicate that depressive symptoms during pregnancy were reliably associated with individual taxa and CST3 in the third trimester. Prediction of functional potential from 16S taxonomy revealed a differential abundance of metabolic pathways in CST1-3 and individual taxa, including biosynthetic pathways for the neuroactive metabolites, serotonin and dopamine. With the exception of bioavailable testosterone, no significant associations were found between symptoms- and stress-related biomarkers and CSTs. Our results provide further evidence of how prenatal psychological distress during pregnancy alters the maternal-fetal microbiome ecosystem that may be important for understanding maternal and child health outcomes.

Association of Pregnant Women's Perinatal Depression with Sociodemographic, Anthropometric and Lifestyle Factors and Perinatal and Postnatal Outcomes: A Cross-Sectional Study

Background: In recent decades, the incidence of depression has gradually increased in the general population globally. Depression is also common during gestation and could result in detrimental gestational complications for both the mother and the fetus. The survey presented aimed to evaluate whether pregnant women's perinatal depression could be associated with socio-demographic, anthropometry and lifestyle factors, and perinatal and postnatal outcomes. Methods: This is a cross-sectional survey conducted on 5314 pregnant women. Socio-demographic and lifestyle factors were recorded by relevant questionnaires via face-to-face interviews. Anthropometric parameters were measured by qualified personnel. Perinatal depressive symptomatology status was evaluated by Beck's Depression Inventory (BDI-II) questionnaire. Results: Depressive symptoms throughout gestation were found in 35.1% of the enrolled women. Perinatal depression was significantly associated with lower educational and economic level, pre-pregnancy regular smoking and reduced levels of Mediterranean diet adherence levels, a higher prevalence of gestational diabetes and preterm birth, as well as a higher incidence of delivering by caesarean section and abnormal childbirth weight. Perinatal depression was also significantly associated with a higher prevalence of maternal postpartum depression and lower prevalence of exclusive breastfeeding practices, as well as with a higher incidence of childhood asthma. Conclusions: Pregnant women's perinatal depression appears to be associated with various socio-demographic, anthropometry, and lifestyle characteristics and with a higher frequency of several adverse pregnancy complications. The present findings emphasize the importance of pregnant women's perinatal mental health, highlighting the need to develop and apply public strategies and policies for psychological counseling and support of future mothers to minimize probable risk factors that may trigger perinatal depression. Novel well-organized, follow-up surveys of enhanced validity are highly recommended to establish more definitive conclusions.

Increasing Access To Perinatal Mental Health Care: The Perinatal Psychiatry Access Program Model

Perinatal psychiatry access programs offer a scalable approach to building the capacity of perinatal professionals to identify, assess, and treat mental health conditions. Little is known about access programs' implementation and the relative merits of differing approaches. We conducted surveys and semistructured interviews with access program staff and reviewed policy and procedure documents from the fifteen access programs that had been implemented in the United States as of March 2021, when the study was conducted. Since then, the number of access programs has grown to thirty state, regional, or national programs. Access programs implemented up to five program components, including telephone consultation with a perinatal psychiatry expert, one-time patient-facing consultation with a perinatal psychiatry expert, resource and referral to perinatal professionals or patients, trainings for perinatal professionals, and practice-level technical assistance. Characterizing population-based intervention models, such as perinatal psychiatry access programs, that address perinatal mental health conditions is a needed step toward evaluating and improving programs' implementation, reach, and effectiveness.

Neonatal treatment with para-chlorophenylalanine (pCPA) induces adolescent hyperactivity associated with changes in the paraventricular nucleus Crh and Trh expressions

Disruption of the brain serotoninergic (5-HT) system during development induces long-lasting changes in molecular profile, cytoarchitecture, and function of neurons, impacting behavioral regulation throughout life. In male and female rats, we investigate the effect of neonatal tryptophan hydroxylase (TPH) inhibition by using para-chlorophenylalanine (pCPA) on the expression of 5-HTergic system components and neuropeptides related to adolescent social play behavior regulation. We observed sex-dependent 5-HT levels decrease after pCPA-treatment in the dorsal raphe nucleus (DRN) at 17 and 35 days. Neonatal pCPA-treatment increased playing, social and locomotory behaviors assessed in adolescent rats of both sexes. The pCPA-treated rats demonstrated decreased Crh (17 days) and increased Trh (35 days) expression in the hypothalamic paraventricular nucleus (PVN). There was sex dimorphism in Htr2c (17 days) and VGF (35 days) in the prefrontal cortex, with the females expressing higher levels of it than males. Our results indicate that neonatal pCPA-treatment results in a long-lasting and sex-dependent DRN 5-HT synthesis changes, decreased Crh, and increased Trh expression in the PVN, resulting in a hyperactivity-like phenotype during adolescence. The present work demonstrates that the impairment of TPH function leads to neurobehavioral disorders related to hyperactivity and impulsivity, such as attention deficit hyperactivity disorder (ADHD).

The association between postpartum depressive symptoms and contraception

BACKGROUND

Postpartum depression affects 10% to 20% of birthing people and is associated with changes in healthcare use. Little is known about the association between postpartum depressive symptoms and choice to use contraception; however, both untreated or undertreated depression and short interpregnancy intervals pose substantial perinatal health risks.

OBJECTIVE

This study aimed to evaluate whether postpartum depressive symptoms are associated with changes in decisions to use any method of contraception.

STUDY DESIGN

This retrospective cohort study included birthing people who delivered between 2017 and 2022 and were referred to a collaborative care program for mental healthcare. Through this program, birthing people with mental health conditions have access to specialized perinatal mental healthcare and prospective symptom monitoring via a patient registry. Postpartum depressive symptoms are assessed via the Patient Health Questionnaire-9, and scores were stratified by severity according to clinical cutoffs. Contraceptive method choice was determined by documentation in the electronic health record and dichotomized as "none" if the participant declined all forms of contraception both at delivery and at the postpartum visit. Bivariable and multivariable analyses were performed.

RESULTS

Of the 1871 participants that met the inclusion criteria, 160 (8.5%) had postpartum Patient Health Questionnaire-9 scores of >14, representing moderately severe or worse depressive symptoms, and 43 (2.3%) had severe (Patient Health Questionnaire-9 of >19) depressive symptoms. Birthing people with higher Patient Health Questionnaire-9 scores were more likely to have medical comorbidities; to have a higher body mass index; to self-identify as Black, Native Hawaiian or Pacific Islander, or Hispanic or Latina; and to have a preterm delivery and less likely to be married or nulliparous than those with Patient Health Questionnaire-9 scores of ≤14. There was no difference in any other sociodemographic or clinical characteristics. The choice to use any contraceptive method decreased with increasing depressive symptoms in bivariable and multivariable analyses, reaching statistical significance in birthing people with severe depressive symptoms (adjusted odds ratio, 2.92; 95% confidence interval, 1.46-5.84).

CONCLUSION

Severe perinatal depressive symptoms are associated with a declination of any form of postpartum contraception. This finding becomes increasingly relevant as abortion access continues to be threatened across the United States, compounding the potential effect of opting not to use contraception.

Association between Maternal Perinatal Stress and Depression on Infant DNA Methylation in the First Year of Life

Maternal stress and depression during pregnancy and the first year of the infant's life affect a large percentage of mothers. Maternal stress and depression have been associated with adverse fetal and childhood outcomes as well as differential child DNA methylation (DNAm). However, the biological mechanisms connecting maternal stress and depression to poor health outcomes in children are still largely unknown. Here we aim to determine whether prenatal stress and depression are associated with changes in cord blood mononuclear cell DNAm (CBMC-DNAm) in newborns (n = 119) and whether postnatal stress and depression are associated with changes in peripheral blood mononuclear cell DNAm (PBMC-DNAm) in children of 12 months of age (n = 113) from the Canadian Healthy Infant Longitudinal Development (CHILD) cohort. Stress was measured using the 10-item Perceived Stress Scale (PSS) and depression was measured using the Center for Epidemiologic Studies Depression Questionnaire (CESD). Both stress and depression were measured at 18 weeks and 36 weeks of pregnancy and six months and 12 months postpartum. We conducted epigenome-wide association studies (EWAS) using robust linear regression followed by a sensitivity analysis in which we bias-adjusted for inflation and unmeasured confounding using the bacon and cate methods. To investigate the cumulative effect of maternal stress and depression, we created composite prenatal and postnatal adversity scores. We identified a significant association between prenatal stress and differential CBMC-DNAm at 8 CpG sites and between prenatal depression and differential CBMC-DNAm at 2 CpG sites. Additionally, we identified a significant association between postnatal stress and differential PBMC-DNAm at 8 CpG sites and between postnatal depression and differential PBMC-DNAm at 11 CpG sites. Using our composite scores, we further identified 2 CpG sites significantly associated with prenatal adversity and 7 CpG sites significantly associated with postnatal adversity. Several of the associated genes, including PLAGL1, HYMAI, BRD2, and ERC2 have been implicated in adverse fetal outcomes and neuropsychiatric disorders. This suggested that differential DNAm may play a role in the relationship between maternal mental health and child health.

The perinatal health secondary to pandemic: association between women's delivery concerns and infant's behavioral problems

BACKGROUND

COVID-19 pandemic characterised a unique and vulnerable social, emotional, and health environment for pregnancy, with potential long-lasting risks to maternal and child health outcomes. In women who were pregnant at the peak of COVID-19 pandemic, we investigated the association between pandemic-related concerns about pregnancy and delivery and both the parent's (i.e. maternal parenting stress) and the infant's (i.e. emotional-behavioral problems) outcomes 12 months after birth.

METHODS

A sample of 352 Italian pregnant women completed a web-based survey from 8 April to 4 May 2020 and a follow-up at 12 months after delivery. Maternal assessment in pregnancy covered prenatal measures for: pandemic-related concerns about pregnancy and childbirth, COVID-19 stressful events exposure, pandemic psychological stress, and mental-health symptoms (i.e. depression, anxiety). The 12 months' assessment covered post-partum measures of social support, parenting stress and maternal reports of infants' behavioral problems.

RESULTS

The results of the Quasi-Poisson regression models on the association between COVID-19 related influencing factors and parenting stress and infant's behavioral problems showed that the presence of higher pandemic-related concerns about pregnancy and childbirth scores was associated with greater total and internalising behavioral problems but not with parenting stress levels.

CONCLUSION

Perinatal mother-infant health has been sensitively threatened by pandemic consequences with maternal concerns about childbirth in pregnancy being associated with 12 months' children's behavioral outcomes. There is a need to invest in psychological support for perinatal women throughout the transition to parenthood to protect risk conditions before they get chronic or severe and influence offspring development.

Predictors of birth weight in pregnant women with malaria: a prospective cohort facility-based study in Webuye-Kenya

In sub-Saharan Africa, malaria, which remains a major public health burden, has a prevalence of 9 to 28% and malaria in pregnancy is associated with severe adverse outcomes for the mother and her baby. Here, we sought to determine the predictors of birth weight in a cohort of 140 women with malaria in pregnancy, who were recruited at the Webuye County hospital in Western Kenya. All study participants underwent malaria diagnosis through microscopic examination of blood smear samples and were grouped into the malaria-positive and malaria-negative groups. Both groups were followed up beginning at the first antenatal visit (March 2022) until delivery (December 2022) and various data, including demographic, parity, gravidity, socioeconomic, maternal and fetal outcomes were collected. Data analyses were done using SPSS version 27. Chi-square and Fisher's Exact tests were used for bivariate and relative risk analyses at a p-value of ≤0.05 (95%) confidence level. Most of the participants were aged 18-25 years, were primigravidas and married, had secondary school-level education, earned 20-30 thousand Kenya shillings, resided in rural areas, and were in the second trimester. There were 6 (4.6%) cases of low birth weight, 3 (4.5%) in the malaria-negative group and 3 (4.7%) in the malaria-positive group. During pregnancy, 41 (31.5%) were anaemic, 5 (3.8%) were HIV-positive, 5 (3.8%) had preeclampsia, and 2 (1.5%) had gestational diabetes. Our analyses show that confounding factors like anaemia, HIV, pre-eclampsia and gestational diabetes did not influence birthweight (p ≥ 0.923). The malaria-positive and malaria-negative groups did not differ significantly with regard to the low birth weight (relative risk: 0.999, 95% confidence interval: 0.926-1.077). Marital status, gestational age, and area of residence were associated with malaria p ≤ 0.001, ≤ 0.001 and 0.028 respectively. In both groups, 124 of the 140 deliveries had normal birth weights and of these 63 (95.4%, n = 70) were in the malaria-negative group, whereas 61 (95.3%, n = 70) belonged to the malaria-positive group.

Experiences of postpartum anxiety during the COVID-19 pandemic: A mixed methods study and demographic analysis

INTRODUCTION

The first wave of the COVID-19 pandemic saw the reconfiguration of perinatal and maternity services, national lockdowns, and social distancing measures which affected the perinatal experiences of new and expectant parents. This study aimed to explore the occurrence of postpartum anxieties in people who gave birth during the pandemic.

METHODS

An exploratory concurrent mixed-methods design was chosen to collect and analyse the quantitative and qualitative data of an online survey during the first UK lockdown. The survey included the Postpartum Specific Anxiety Scale-Research Short Form-for use in global Crises [PSAS-RSF-C] psychometric tool, and open-ended questions in relation to changes in birth plans and feelings about those changes and giving birth in a pandemic. Differences in measured scores were analysed for the participant's ethnicity, sexual orientation and disability using independent Student's t-tests, and for age, the analysis was completed using Pearson's correlation. Qualitative data from open-ended questions were analysed using a template analysis.

RESULTS

A total of 1,754 new and expectant parents completed the survey between 10th and 24th April 2020, and 381 eligible postnatal women completed the psychometric test. We found 52.5% of participants reported symptoms consistent with a diagnosis of postnatal anxiety-significantly higher than the rates usually reported. Younger women and sexual minority women were more likely to score highly on the PSAS-RSF-C than their older or heterosexual counterparts (p<0.001). Younger participants reported anxieties in the 'infant safety and welfare' category, whilst lesbian, gay, bisexual, and pansexual participants scored highly in the 'psychosocial adjustment to motherhood' category.

DISCUSSION

Postpartum anxiety is under-reported, and demographic differences in the rates of postpartum anxiety are under-researched. This research demonstrates for the first time a difference in postpartum anxiety rates amongst sexual minority women.

Maternal Antibiotic Exposure and the Risk of Developing Antenatal Depressive Symptoms

Background: Antenatal depression is common and has significant consequences. The literature suggests that antibiotic exposure may be associated with depression. Many individuals are exposed to antibiotics during pregnancy. Further investigation of the association between antenatal antibiotic use and the development of depression during pregnancy is needed. Methods: A national prospective observational cohort study of pregnant individuals was undertaken using an online survey, completed during the third trimester. Antenatal depressive symptoms (ADSs) were defined as having an Edinburgh Postnatal Depression Scale score of ≥13 and/or receiving a clinical diagnosis of depression. Results: One in six individuals (16.5%, n = 977) experienced ADSs during their pregnancy, of whom 37.9% received a depression diagnosis. There was no relationship between antibiotic use and the development of ADSs. Four factors were identified as significant independent predictors of ADSs: personal history of depression, severe nausea and vomiting causing an inability to eat, emotional abuse from an intimate partner within the prior 12 months, and not having a university degree. Conclusions: Antenatal antibiotic use was not associated with the development of ADSs. Given the high incidence of undiagnosed depression, new strategies and models of care that prioritise individuals with risk factors may be required to optimise antenatal care.

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

Background

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

Methods

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

Results

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

Conclusion

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

The Pressing Need to Integrate Mental Health into Obstetric Care

Mental health and substance use conditions are prevalent among perinatal individuals. These conditions have a negative impact on the health of perinatal individuals, their infants, and families, yet are underdiagnosed and undertreated. Populations that have been marginalized disproportionately face barriers to accessing care. Integrating mental health into obstetric care could address the perinatal mental health crisis. We review perinatal mental health conditions and substance use, outline the impact associated with these conditions, and describe the promise and potential of integrating mental health into obstetric settings to improve outcomes for patients receiving obstetric and gynecologic care.

Behavioral Health Integration on Inpatient Obstetric Units: Program Development, Strategies for Implementation, and Lessons Learned

Perinatal mood and anxiety disorders and substance use disorders are the primary causes of maternal mortality in the postpartum period and represent major public health concerns. Despite this, these conditions remain undertreated. Behavioral health integration in outpatient obstetric settings is necessary but insufficient to meet the needs of all patients. Inpatient behavioral health integration represents a promising avenue for addressing gaps in care. Results from recent program development indicate that needs assessment, stakeholder backing, collaboration with existing programs, and adaptability are key factors in successful implementation.

Integrating Mental Health Care in Ambulatory Obstetrical Practices: Strategies and Models

Perinatal mental health is recognized as a priority component of obstetrical care. Perinatal patients often turn to their obstetrician for help with mental health concerns as they view them as their primary health care provider. Unfortunately, obstetricians face challenges in providing adequate support due to time constraints and limited expertise. Integrated behavioral health care offers a collaborative and cost-effective solution to enhance patient care and clinician satisfaction. Integrated behavioral health clinicians possess fundamental skills to care for patients throughout the reproductive lifespan and assist obstetricians in identifying and managing common mood concerns.

Adequacy of prenatal care utilisation and gestational weight gain among women with depression

BACKGROUND

Depression is common during pregnancy, can elevate risk for excessive or inadequate gestational weight gain (GWG), and is associated with both underutilisation and overutilisation of prenatal care. Whether GWG is associated with adequacy of prenatal care among women with and without depression in the United States is unknown. This study evaluated whether adequacy of prenatal care differed by depression status and GWG.

METHODS

Data from the Pregnancy Risk Assessment Monitoring System from 1,379,870 women who were pregnant with a singleton and delivered at 37-42 weeks gestation during 2016 to 2018 were included. Depression was self-reported. The Kotelchuck index was used to evaluate adequacy of prenatal care. Maternal weight gain was compared to GWG guidelines.

RESULTS

Approximately 13.1% of the sample experienced depression during pregnancy. Although those with depression had increased odds of both inadequate and above adequate levels of prenatal care, this association was no longer significant after accounting for demographics, medical comorbidities, and socioeconomic factors. Individuals with inadequate levels of prenatal care with a normal pre-pregnancy body mass index gained less weight during pregnancy.

CONCLUSIONS

The association between depression and prenatal care utilisation seems driven by demographic, medical comorbidity, and socioeconomic variables. Weight outcomes were associated with inadequate prenatal care utilisation.

Perinatal depression and its associated risk factors during the COVID-19 pandemic in low- and middle-income countries: a systematic review and meta-analysis

PURPOSE

Perinatal depression significantly impacts maternal and child health, with further complexities arising during the COVID-19 pandemic. This review is the first to comprehensively synthesize evidence on the prevalence of perinatal depression and its associated risk factors in Low- and Middle-Income Countries (LMICs) during the pandemic period.

METHODS

The study protocol was registered in PROSPERO (CRD42022326991). This review followed the Joanna Briggs Institute (JBI) guideline for prevalence studies. A comprehensive literature search was conducted in six databases: PubMed, Scopus, Web of Science, PsycInfo, CINAHL, and ProQuest. Pooled prevalence estimates were computed for both prenatal and postnatal depression. Identified risk factors were summarized narratively.

RESULTS

A total of 5169 studies were screened, out of which 58 were included in the narrative review and 48 [prenatal (n = 36) and postnatal (n = 17)] were included in the meta-analysis. The pooled depression prevalence for prenatal women was 23% (95% CI: 19-27%), and for the postnatal women was 23% (95% CI: 18-30%). Maternal age, education, perceived fear of COVID-19 infection, week of pregnancy, pregnancy complications, and social and family support were identified as associated risk factors for depression.

CONCLUSIONS

Our review demonstrates an increased prevalence of perinatal depression during the COVID-19 pandemic in LMICs. It sheds light on the significant burden faced by pregnant and postnatal women and emphasizes the necessity for targeted interventions during the ongoing and potential future crisis.

Prenatal mood and anxiety disorders and associated cytokine changes

BACKGROUND

We examined whether women with prenatal mood and anxiety disorders would exhibit differential pro- and anti-inflammatory marker trajectories during the prenatal and postpartum periods compared to women without these disorders.

METHODS

Approximately 179 pregnant women participated in a longitudinal study conducted in two urban areas. Blood samples for inflammatory markers were collected at six study visits. The Structured Clinical Interview for the DSM-IV (SCID) was administered to participants scoring above cutoffs on anxiety and depression. Pregnant women with SCID Axis I diagnoses of mood and/or anxiety disorders were compared to other participants on inflammatory markers. Multilevel modeling tested associations between SCID diagnoses and within-person interleukin (IL)6 and IL10 trajectories.

RESULTS

Prenatal SCID diagnoses were associated with linear, quadratic and cubic change in IL6 from prenatal to postpartum timepoints. Women with a prenatal SCID diagnosis had steeper decreases and increases in IL6 during prenatal and postpartum periods. SCID diagnoses were associated with lower IL10 in mid-pregnancy to postpartum (b = -0.078, SE = 0.019; p = .015).

LIMITATIONS

Future studies would benefit from a larger sample size and a larger number of participants with SCID diagnoses. Future research should also examine whether different prenatal Axis 1 diagnoses are associated with different patterns of immune response in pregnancy.

CONCLUSIONS

Pregnant women with prenatal mood and anxiety disorders had greater fluctuations in IL6 across prenatal and postpartum periods and lower IL10 through pregnancy and postpartum. They may have different proinflammatory states that remain after birth without a reciprocal anti-inflammatory response.

Addressing the challenges of integrating care for perinatal depression in primary care in Nigeria

PURPOSE

This report provides the results of a task-shared approach for integrating care for perinatal depression (PND) within primary maternal and child healthcare (PMCH), including the factors that may facilitate or impede the process.

METHODS

This hybrid implementation-effectiveness study guided by the Replicating Effective Programmes framework was conducted in 27 PMCH clinics in Ibadan, Nigeria. The primary implementation outcome was change in the identification rates of PND by primary health care workers (PHCW) while the primary effectiveness outcome was the difference in symptom remission (EPDS score ≤ 5) 6 months postpartum. Outcome measures were compared between two cohorts of pregnant women, one recruited before and the other after training PHCW to identify and treat PND. Barriers and facilitators were explored in qualitative interviews.

RESULTS

Identification of PND improved from 1.4% before to 17.4% after training; post-training rate was significantly higher in clinics where PHCW routinely screened using the 2-item patient health questionnaire (24.8%) compared to non-screening clinics (5.6%). At 6-months postpartum, 60% of cohort one experienced remission from depression, compared to 56.5% cohort two [OR-0.9 (95%CI-0.6, 1.3) p = 0.58]. Identified facilitators for successful integration included existence of policy specifying mental health as a component of PHC, use of screening to aid identification and supportive supervision, while barriers included language and cultural attitudes towards mental health and human resource constraints. PHCW were able to make adaptations to address these barriers.

CONCLUSIONS

Successful implementation of task-shared care for perinatal depression requires addressing staff shortages and adopting strategies that can improve identification by non-specialist providers.

Recentering responsible and explainable artificial intelligence research on patients: implications in perinatal psychiatry

In the setting of underdiagnosed and undertreated perinatal depression (PD), Artificial intelligence (AI) solutions are poised to help predict and treat PD. In the near future, perinatal patients may interact with AI during clinical decision-making, in their patient portals, or through AI-powered chatbots delivering psychotherapy. The increase in potential AI applications has led to discussions regarding responsible AI and explainable AI (XAI). Current discussions of RAI, however, are limited in their consideration of the patient as an active participant with AI. Therefore, we propose a patient-centered, rather than a patient-adjacent, approach to RAI and XAI, that identifies autonomy, beneficence, justice, trust, privacy, and transparency as core concepts to uphold for health professionals and patients. We present empirical evidence that these principles are strongly valued by patients. We further suggest possible design solutions that uphold these principles and acknowledge the pressing need for further research about practical applications to uphold these principles.

Reproductive outcomes among female health care workers

OBJECTIVE

Occupational exposures may be associated with reproductive health and pregnancy outcomes. This study investigated the association between occupational exposures and reproductive health, pregnancy outcomes, and the lactation period among hospital staff.

MATERIALS AND METHODS

Seven hundred thirty-three female healthcare workers from hospitals affiliated with the Tehran University of Medical Sciences were invited to participate in this cross-sectional study. The measurement method for fertility consequences was self-report. Demographic characteristics, occupational data, medical history, and reproductive history were collected via data collection form. Finally, reproductive outcomes were evaluated in different occupational hazard categories.

RESULT

Chemical exposures (solvents) were a risk factor for stillbirth. Prolonged working hours were associated with spontaneous abortion and breastfeeding periods. Shift workers did not have a higher frequency of reproductive and pregnancy outcomes, but the breastfeeding period was significantly decreased in shift workers. Psychiatric disorders were associated with preterm labour, low birth weight, and stillbirth in sequence with nervousness, depression, and mood disturbance. Furthermore, depression affects the breastfeeding period. Moreover, we found a link between job titles and infertility. In addition, socioeconomic status was related to stillbirth and infertility.

CONCLUSION

The study revealed that chemical and ergonomic exposures have associations with some reproductive outcomes. We also conclude that shift work could adversely affect the breastfeeding period. So, implementing some organizational strategies to control adverse health effects of occupational hazards and modifying shift work and working hours for nursing mothers is recommended.

Psyche: The 5th 'P' and its Associated Impact on the Second Stage of Labor

OBJECTIVE

Patients with depression during labor display dysregulated patterns of oxytocin release and this may impact second stage of labor. The objective of this study was to evaluate the association between maternal preconception and antenatal depressive disorders on the duration of second stage of labor and perinatal outcomes.

STUDY DESIGN

Secondary analysis of patients enrolled in the Behavioral and Mood in Mothers, Behavior in Infants study who reached the second stage of labor. Participants were assigned to: pre-conception only major depressive disorder (MDD), prenatal major depressive disorder, and non-depressed controls. Primary outcome was prolonged second stage of labor. Secondary outcomes included perinatal morbidities.

RESULTS

172 patients were included. 24.4% (42/172) participants had preconception-only MDD, 42.4% (73/172) patients had prenatal MDD, and 33.1% (57/172) patients had as non-depressed controls. The adjusted pair-wise analysis between groups showed no significant difference in the duration of second stage. No statistically significant differences were noted between groups for adverse neonatal outcomes.

CONCLUSION

Maternal depressive disorders did not impact length of second stage of labor or immediate perinatal outcomes.

Review of the Assessment and Management of Perinatal Mood and Anxiety Disorders

Perinatal mood and anxiety disorders (PMADs) are the most common complication of childbirth. When poorly controlled, they are associated with worse obstetric outcomes, such as higher rates of preterm birth and unplanned cesarean delivery. They are also associated with suicide, a leading cause of perinatal maternal death. This article provides an overview of evidence-based recommendations for screening, assessment, and management of PMADs, including suicide risk assessment and management and pharmacological and nonpharmacological treatment options compatible with pregnancy and lactation. Although specialized reproductive psychiatrists can provide expert guidance for the management of PMADs, their scarcity means that most patients will not have access to this expert care and instead will seek guidance from general psychiatrists. This article provides a clinical guide for generalists that is based on the best current evidence, including recently released treatment guidelines.

Vulnerabilities and reparative strategies during pregnancy, childbirth, and the postpartum period: moving from rhetoric to action

Maternal outcomes throughout pregnancy, childbirth, and the postnatal period are influenced by interlinked and interdependent vulnerabilities. A comprehensive understanding of how various threats and barriers affect maternal and perinatal health is critical to plan, evaluate and improve maternal health programmes. This paper builds on the introductory paper of the Series on the determinants of maternal health by assessing vulnerabilities during pregnancy, childbirth, and the postnatal period. We synthesise and present the concept of vulnerability in pregnancy and childbirth, and map vulnerability attributes and their dynamic influence on maternal outcomes in early and late pregnancy and during childbirth and the postnatal period, with a particular focus on low-income and middle-income countries (LMICs). We summarise existing literature and present the evidence on the effects of various reparative strategies to improve pregnancy and childbirth outcomes. Lastly, we discuss the implications of the identified vulnerability attributes and reparative strategies for the efforts of policymakers, healthcare professionals, and researchers working towards improving outcomes for women and birthing people in LMICs.

Maternal and Neonatal Risk Factors Associated with Perinatal Depression-A Prospective Cohort Study

Background

Perinatal depression (PND) is often under-treated and under-recognized. It has a negative impact on infant development and mother-child interactions. This study aims to estimate the prevalence of PND during pregnancy and in the postpartum period and the effect of sociodemographic factors, psychosocial stressors, and obstetric and neonatal factors on PND.

Methods

166 antenatal mothers attending tertiary center, who completed the 1st-trimester, were evaluated on baseline sociodemographic, psychosocial, obstetric, neonatal, and post neonatal factors by using a semi-structured questionnaire. Periodic prospective assessments were done using Hamilton depression rating scale (HAMD) at the end of the second and third trimesters and first and sixth weeks of the postpartum period.

Results

Prevalence of PND was 21.7%, 32.2%, 35%, 30.4%, and 30.6%, at the end of the first trimester, during second, and third trimesters, and first and sixth week postpartum, respectively. Factors significantly associated with depressive symptoms included history of previous children with illness (P: 0.013, OR-5.16, CI-1.3-19.5) and preterm birth (P: 0.037, OR-3.73, CI-1.1- 13.2) at the time of recruitment; history of abuse (P: 0.044, OR-3.26, CI-1.1-10.8) and marital conflicts (P: 0.003, OR-3.2, CI-1.4-6.9) by the end of second trimester; history of miscarriages (P: 0.012, OR-2.58, CI-1.2-5.4) by the end of third trimester; lower SES (P: 0.001, OR-3.48, CI-1.64-7.37), unsatisfied living conditions (P: 0.004, OR-2.9, CI-1.4-6.04), alcohol use in husband (P: 0.049, OR-2.01, CI-1.1-4.11), history of depressive episodes (P: 0.049, OR-2.09, CI-1.1-4.46), history of high-risk pregnancy (P: 0.008, OR-2.7, CI-1.29-5.64), history of miscarriages (P: 0.049, OR-2.04, CI-1.1-4.2), stressful events in the postpartum period (P: 0.043, OR-2.58, CI-1.01-6.59), IUD (P: 0.002), preterm birth (P: 0.001), congenital malformations (P: 0.001), dissatisfaction with the sex of the child (P: 0.005, OR-3.75, CI-1.42-9.91), poor family support (P: 0.001), and low birth weight (P: 0.001, OR-16.78, CI-6.32-44.53) in the postpartum period. These analyses are purely exploratory.

Conclusions

PND is highly prevalent from the early antenatal period onwards; this warrants periodic assessment of depression among high-risk mothers, using a validated tool, for early diagnosis and management.

Effectiveness of two systems-level interventions to address perinatal depression in obstetric settings (PRISM): an active-controlled cluster-randomised trial

BACKGROUND

Perinatal depression is a common and undertreated condition, with potential deleterious effects on maternal, obstetric, infant, and child outcomes. We aimed to compare the effectiveness of two systems-level interventions in the obstetric setting-the Massachusetts Child Psychiatry Access Program (MCPAP) for Moms and the PRogram In Support of Moms (PRISM)-in improving depression symptoms and participation in mental health treatment among women with perinatal depression.

METHODS

In this cluster-randomised, active-controlled trial, obstetric practices across Massachusetts (USA) were allocated (1:1) via covariate adaptive randomisation to either continue participating in the MCPAP for Moms intervention, a state-wide, population-based programme, or to participate in the PRISM intervention, which involved MCPAP for Moms plus a proactive, multifaceted, obstetric practice-level intervention with intensive implementation support. English-speaking women (aged ≥18 years) who screened positive for depression (Edinburgh Postnatal Depression Scale [EPDS] score ≥10) were recruited from the practices. Patients were followed up at 4-25 weeks of gestation, 32-40 weeks of gestation, 0-3 months postpartum, 5-7 months postpartum, and 11-13 months postpartum via telephone interview. Participants were masked to the intervention; investigators were not masked. The primary outcome was change in depression symptoms (EPDS score) between baseline assessment and 11-13 months postpartum. Analysis was done by intention to treat, fitting generalised linear mixed models adjusting for age, insurance status, education, and race, and accounting for clustering of patients within practices. This trial is registered with ClinicalTrials.gov, NCT02760004.

FINDINGS

Between July 29, 2015, and Sept 20, 2021, ten obstetric practices were recruited and retained; five (50%) practices were randomly allocated to MCPAP for Moms and five (50%) to PRISM. 1265 participants were assessed for eligibility and 312 (24·7%) were recruited, of whom 162 (51·9%) were enrolled in MCPAP for Moms practices and 150 (48·1%) in PRISM practices. Comparing baseline to 11-13 months postpartum, EPDS scores decreased by 4·2 (SD 5·2; p<0·0001) among participants in MCPAP for Moms practices and by 4·3 (SD 4.5; p<0·0001) among those in PRISM practices (estimated difference between groups 0·1 [95% CI -1·2 to 1·4]; p=0·87).

INTERPRETATION

Both the MCPAP for Moms and PRISM interventions were equally effective in improving depression symptoms. This finding is important because the 4-point decrease in EPDS score is clinically significant, and MCPAP for Moms has a lower intensity and greater population-based reach than does PRISM.

Rural/urban differences in health care utilization and costs by perinatal depression status among commercial enrollees

PURPOSE

To understand differences in health care utilization and medical expenditures by perinatal depression (PND) status during pregnancy and 1-year postpartum overall and by rural/urban status.

METHODS

We estimated differences in health care utilization and medical expenditures by PND status for individuals with an inpatient live-birth delivery in 2017, continuously enrolled in commercial insurance from 3 months before pregnancy through 1-year postpartum (study period), using MarketScan Commercial Claims data. Multivariable regression was used to examine differences by rurality.

FINDINGS

Ten percent of commercially insured individuals had claims with PND. A smaller proportion of rural (8.7%) versus urban residents (10.0%) had a depression diagnosis (p < 0.0001). Of those with PND, a smaller proportion of rural (5.5%) versus urban residents (9.6%) had a depression claim 3 months before pregnancy (p < 0.0001). Compared with urban residents, rural residents had greater differences by PND status in total inpatient days (rural: 0.7, 95% confidence interval [CI]: 0.6-0.9 vs. urban: 0.5, 95% CI: 0.5-0.6) and emergency department (ED) visits (rural: 0.7, 95% CI: 0.6-0.9 vs. urban: 0.5, 95% CI: 0.4-0.5), but a smaller difference by PND status in the number of outpatient visits (rural: 9.2, 95% CI: 8.2-10.2 vs. urban: 13.1, 95% CI: 12.7-13.5). Differences in expenditures for inpatient services by PND status differed by rural/urban status (rural: $2654; 95% CI: $1823-$3485 vs. urban: $1786; 95% CI: $1445-$2127).

CONCLUSIONS

Commercially insured rural residents had more utilization for inpatient and ED services and less utilization for outpatient services. Rural locations can present barriers to evidence-based care to address PND.

Perinatal dietary patterns and symptomatic depression: A prospective cohort study

To promote maternal and infant health, there is a need to optimise the dietary pattern of pregnant women to reduce perinatal depression. This prospective cohort study was conducted from June 2020 to February 2022, 300 women from a medical center were interviewed during late pregnancy and at 4-6 weeks postpartum. Dietary patterns were derived by factor analysis using a semiquantitative food frequency questionnaire. Symptomatic depression was defined using the Edinburgh Postpartum Depression Scale (EPDS, ranged 0-30). Their dairy, vegetable and fruit intakes were below the Taiwanese recommendations for pregnant women. Symptomatic depression (EPDS ≥10) affected 31.3% in the third trimester and 35.7% postpartum. Pre- and post-EPDS scores were positively correlated (r = 0.386, p < 0.001). Approximately 55% of those depressed before delivery were also depressed postpartum. For late pregnancy, four dietary patterns were identified ('Good oil', 'Vegetables and fruits', 'Omnivorous' and 'Refined-grain and organ meats'). Dietary patterns were classified according to quartiles (Q). Higher omnivorous pattern scores reduced the risk of depression. For prenatal depression, with Q1 as a reference, the risk was reduced by 38% for Q2, 43% for Q3 and 59% for Q4 (p for trend = 0.068). These findings became evident postpartum (reduced risk by 68% for Q2, 69% for Q3 and 70% for Q4 (p = 0.031; p for trend = 0.0032). The association between dietary patterns and depression encourages the routine nutritional management of pregnant women.

Improvements in cardiovascular health over the perinatal period predicts lower postpartum psychological distress

Background

Adverse cardiovascular events during pregnancy (e.g., pre-eclampsia) occur at higher rates among individuals with pre-pregnancy overweight or obesity (body mass index [BMI]≥25kg/m2) and have been associated with postpartum depression. However, it is unclear whether cardiovascular health (CVH), defined more holistically than the absence of cardiovascular conditions in pregnancy, relates to postpartum psychological functioning. The present study examined whether changes in CVH during the perinatal period predicted postpartum psychological functioning among individuals with pre-pregnancy BMI≥25kg/m2.

Methods

Individuals (N=226; Mage=28.43±5.4 years; MBMI=34.17±7.15kg/m2) were recruited when their pregnancies were 12-20 weeks gestation (M=15.64±2.45 weeks) for a longitudinal study of health and well-being. Participants completed the Center for Epidemiological Studies Depression Scale (CES-D) and Perceived Stress Scale (PSS) and reported on CVH behaviors (dietary intake, physical activity, nicotine exposure, and sleep) at baseline and at 6-months postpartum. BMI and CVH behaviors were coded according to the American Heart Association's Life's Essential 8 to create a CVH score at both timepoints. Linear regression analyses were performed to examine whether change in CVH related to postpartum CES-D and PSS scores. Because sleep was only measured in a subset of participants (n=114), analyses were conducted with and without sleep included. Baseline CVH, CES-D and PSS scores, and demographic factors were included as covariates in all models.

Results

Improved CVH was associated with lower postpartum CES-D (β=-0.18, p<0.01) and PSS (β=-0.13, p=0.02) scores when excluding sleep. Compared to those whose CVH improved by >1SD from pregnancy to 6-months postpartum, individuals whose CVH worsened by >1SD scored 6.42 points higher on the CESD (MCESD=15.25±10.92 vs. 8.52±6.90) and 6.12 points higher on the PSS (MPSS=24.45±8.29 vs. 17.83±8.70). However, when including sleep, these relationships were no longer significant (ps>0.4).

Conclusions

Improvements in CVH from early pregnancy to 6-months postpartum were associated with lower postpartum depressive symptoms and perceived stress. However, these relationships were no longer significant when including sleep in the CVH metric, potentially due to the large reduction in sample size. These data suggest that intervening during pregnancy to promote CVH may improve postpartum psychological functioning among high-risk individuals.

Denis I, Zhu W, Mahaffey B, Lobel M. Anxiety trajectories from pregnancy to one-year postpartum and their contributors during the COVID-19 pandemic

BACKGROUND

Anxiety in the peripartum period (pregnancy through one-year postpartum) has negative impacts on mothers and infants. During the COVID-19 pandemic, high rates of anxiety were reported worldwide, but trajectories for how these symptoms change longitudinally in the peripartum period remain unknown.

METHODS

A total of 1,411 women who were pregnant during the second U.S. COVID-19 surge completed four study questionnaires between December 2020 and March 2022, including assessments of anxiety symptoms (GAD-7) and individual and community-level contributors. Latent Class Growth Mixture Models (LCGMM) were used to identify anxiety trajectories, and multinomial logistic regression was used to identify contributors to class membership.

RESULTS

Three classes of anxiety symptom trajectories were identified. Class 1 (n = 956, 67.8%) experienced minimal/mild anxiety throughout the peripartum period. Class 2 (n = 362, 25.7%) experienced initial moderate anxiety that remained stable. Class 3 (n = 93, 6.6%) experienced initial moderate anxiety that increased to severe in the postpartum period. Stress and history of mental health diagnosis contributed to higher initial levels of anxiety and ongoing social support contributed to lower levels of anxiety. In addition, financial insecurity increased the risk of belonging to Class 3.

CONCLUSIONS

Screening for anxiety symptoms and psychosocial vulnerabilities in the peripartum period is vital, as is early intervention. This is especially the case among women with limited financial and social resources who may experience chronic or worsening anxiety as they transition to parenthood.

Effect of adverse perinatal outcomes on postpartum maternal mental health in low-income and middle-income countries: a protocol for systematic review

INTRODUCTION

More than three-fourths of adverse perinatal outcomes (preterm, small for gestational age, low birth weight, congenital anomalies, stillbirth and neonatal death) occur in low-income and middle-income countries. These adverse perinatal outcomes can have both short-term and long-term consequences on maternal mental health. Even though there are few empirical studies on the effect of perinatal loss on maternal mental illness, comprehensive information on the impact of adverse perinatal outcomes in resource-limited settings is scarce. Therefore, we aim to systematically review and synthesise evidence on the effect of adverse perinatal outcomes on maternal mental health.

METHODS AND ANALYSIS

The primary outcome of our review will be postpartum maternal mental illness (anxiety, depression, post-traumatic stress disorder and postpartum psychosis) following adverse perinatal outcomes. All peer-reviewed primary studies published in English will be retrieved from databases: PubMed, MEDLINE, CINAHL Ultimate (EBSCO), PsycINFO, Embase, Scopus and Global Health through the three main searching terms-adverse perinatal outcomes, maternal mental illness and settings, with a variant of subject headings and keywords. We will follow the Joanna Briggs Institute critical appraisal checklist to assess the quality of the studies we are including. The review findings will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. Estimate-based meta-analysis will be performed. We will assess heterogeneity between studies using the I2 statistics and publication bias will be checked using funnel plots and Egger's test. A subgroup analysis will be conducted to explore potential sources of heterogeneity (if available). Finally, the certainty of the evidence will be evaluated using the Grading of Recommendations, Assessment, Development and Evaluation approach.

ETHICS AND DISSEMINATION

Since this systematic review does not involve human participants, ethical approval is not required. The review will be submitted for publication in a peer-reviewed journal.

Phenotypic Environmental Sensitivity and Mental Health During Pregnancy and Post Partum: Protocol for the Experiences of Pregnancy Longitudinal Cohort Study

BACKGROUND

Mental health problems during pregnancy and post partum are common and associated with negative short- and long-term impacts on pregnant individuals, obstetric outcomes, and child socioemotional development. Socio-environmental factors are important predictors of perinatal mental health, but the effects of the environment on mental health are heterogeneous. The differential susceptibility theory and the environmental sensitivity framework suggest that individuals differ in their degree of sensitivity to positive and negative environments, which can be captured by individual phenotypes such as temperament and personality. While there is strong evidence for these models in childhood, few studies examined them in adults, and they were not examined in pregnancy.

OBJECTIVE

The primary objective of the Experiences of Pregnancy study is to explore whether childhood and current environments are associated with mental health and well-being in pregnancy and whether these effects depend on individual sensitivity phenotypes (personality). This study also aims to gather important psychosocial and health data for potential secondary data analyses and integrative data analyses.

METHODS

We will conduct a longitudinal cohort study. The study was not registered elsewhere, other than this protocol. Participants will be recruited through social media advertisements linking to the study website, followed by an eligibility call on Zoom (Zoom Video Communications). Participants must be aged 18 years or older, currently residing in the United States as citizens or permanent residents, and currently planning to continue the pregnancy. A minimum of 512 participants will be recruited based on power analyses for the main objectives. Since the data will also be a resource for secondary analyses, up to 1000 participants will be recruited based on the available budget. Participants will be in their first trimester of pregnancy, and they will be followed at each trimester and once post partum. Data will be obtained through self-reported questionnaires assessing demographic factors; pregnancy-related factors; delivery, labor, and birth outcomes; early infant feeding; individual personality factors; childhood and current environments; mental health and well-being; attachment; and infant temperament. A series of measures were taken to safeguard the study from web robots and fraudulent participants, as well as to reduce legal and social risks for participants following Dobbs v. Jackson.

RESULTS

The study received ethics approval in April 2023 from the University of Oklahoma-Norman Campus Institutional Review Board. Recruitment occurred from May to August 2023, with 3 follow-ups occurring over 10 months.

CONCLUSIONS

The Experiences of Pregnancy study will extend theories of environmental sensitivity, mainly applied in children to the perinatal period. This will help better understand individual sensitivity factors associated with risk, resilience, plasticity, and receptivity to negative and positive environmental influences during pregnancy for pregnant individuals.
