Moderate antenatal anxiety symptoms and birth outcomes of boys and girls

Anxiety in a Specialist Perinatal Mental Health Service: patient characteristics, management, and outcomes

OBJECTIVES

To outline characteristics of patients with anxiety diagnoses attending a Specialist Perinatal Mental Health Service (SPMHS) in Ireland, the mental health care received by those patients, mental health and obstetric outcomes for those patients, and immediate neonatal outcomes for their babies.

METHODS

A retrospective chart review was conducted of patients with antenatal anxiety diagnoses who attended the SPMHS in University Maternity Hospital Limerick, from initiation of the service to the end of its first year.

RESULTS

Data were collected on 100 patients, 81 with a mental health diagnosis prior to attending the SPMHS, 32 with prior engagement with psychiatry, and 23 with a previous perinatal diagnosis. The mean age of patients was 32.4 (19-47, std 6.158). Beyond initial assessment, the Mental Health Midwife was involved in the care of 61% of patients, more than any other specialty including psychiatry. Twenty-seven patients had psychiatric medication either started or altered by the SPMHS. The most common reason for eventual discharge was that patients were well. Two patients presented in mental-health-related crisis to emergency services and one patient was admitted to an acute psychiatric ward.

CONCLUSIONS

Patients attending the SPMHS for anxiety spanned a broad spectrum of demographics and diagnoses and received varied set of interventions. A significant proportion of patients had a primary diagnosis of Pregnancy-related anxiety. The Mental Health Midwife played a key role in management of these patients. Though rates of mental health crises and admissions were low, the absence of a Mother and Baby Unit in Ireland was highlighted.

Impact of the trait anxiety during pregnancy on birth weight: an observational cohort study

To explore the effects of antenatal anxiety on fetal growth an observational cohort study was performed, including a cohort of 204 women with singleton pregnancies during the strict lockdown of the COVID-19 pandemic in 2020. Psychosocial factors, maternal demographics, obstetric outcomes, social support (Medical Outcomes Study Social Support Survey, MOS-SSS), and symptoms of anxiety (State-Trait Anxiety Inventory, STAIs and STAIt) and depression (Edinburgh Postpartum Depression Scale, EPDS) were studied as potential predictors of low birth weight. Main outcome measures were birth weight, head circumference and length. Results showed a negative correlation between STAIt score (trait anxiety) and birth weight percentile (r = -0.228, p = .047). In the univariate linear regression analysis, a lower maternal weight and BMI before pregnancy, parity, increased STAIt score and preterm birth below 37 weeks of gestation (p = .008, p = .015, p = .028, p = .047 and p = .022, respectively) were identified as predictive risk factors for low birth weight, whereas in the multivariate lineal regression analysis only a lower maternal weight before pregnancy and an increased STAIt score were independent predictors for low birth weight (p = .020, p = .049, respectively). To conclude, anxiety during pregnancy impacts birth weight, and specifically the trait anxiety, is a predictor for low birth weight.

Effects of maternal anxiety on fetal and maternal circulation

OBJECTIVE

The aim of this study was to evaluate the association between maternal anxiety in the third trimester and changes in fetal and maternal circulation assessed by Doppler velocimetry.

METHODS

This is a prospective, cross-sectional study. The inclusion criteria were good health, a singleton pregnancy, maternal age between 18 and 40 years, and gestational age between 34 and 40 weeks. Doppler measurements included mean uterine artery pulsatility index, fetal middle cerebral artery pulsatility index, peak of systolic velocity, umbilical artery, and umbilical vein. The Beck Anxiety Inventory questionnaire, validated for the Brazilian population, with 21 self-reported items, was applied.

RESULTS

The study included 34 pregnant women, and 6 (17.7%) presented a total Beck Anxiety Inventory score showing moderate or severe maternal anxiety. The mean maternal age was 28.1 years (SD 5.7 years); the mean gestational age at interview was 36.5 weeks (SD 1.8 weeks), and the mean Beck Anxiety Inventory total score was 12.3 (SD 9.8). The group with moderate or severe anxiety, compared to the group with minimal or mild anxiety, presented an association with lower maternal age (median 21.5 vs. 29.5 years, p=0.019), lower fetal umbilical vein blood flow (median 189.4 vs. 249.5 mL/min, p=0.047), and lower umbilical vein-corrected blood flow (median 68.5 vs. 84.9 mL/kg/min, p=0.038).

CONCLUSION

Maternal anxiety may affect fetal circulation patterns in late pregnancy and is associated with reduced blood flow in the fetal umbilical vein. The underlying physiopathology needs further investigation.

Association between cognitive representation of illness and the outcome of patients with premature coronary artery disease

OBJECTIVE

To assess whether illness perception (IP) in overall and each of its three dimensions (cognitive, emotional and comprehension) have an independent prognostic value in men and women with premature coronary artery disease (CAD).

METHODS

In a prospective cohort, 778 patients (370 men and 408 women) with premature CAD(diagnosed in men aged<45 y and women aged<55 y), who had completed brief illness perception questionnaire were followed up for 4 years. Outcome event was defined as composite of all-cause mortality, nonfatal myocardial infarction(MI), repeated revascularization or/and stroke. Analysis was performed for men and women separately. High scores for each item of illness perception indicate positive perception.

RESULTS

Among men, 90 patients (24.3%) experienced events: 14(3.8%) death, 23(6.2%) nonfatal MI, 9(2.4%) strokes, and 44(11.9%) revascularization. Men with and without event showed no difference regarding the traditional risk factors, depression and anxiety symptoms. Among women, 72(17.6%) had events: 11(2.7%) death, 23(5.6%) nonfatal MI, 7(1.7%) strokes and 31(7.6%) revascularization; who had a lower education, more severe CAD, and more depressive symptoms. After adjustments for potential confounders, overall IP and only its cognitive dimension were significantly associated with the outcome in women:1-score increase in the women's cognitive perception resulted in an 18% decrease in the event (HR = 0.82, 95% CI:0.72 to 0.95; P = 0.007). In the men, this effect remained nonsignificant either for IP or its dimensions.

CONCLUSIONS

Positive cognitive representation of illness was predictive of a decreased likelihood of mortality and/or cardiovascular events in women with premature CAD. Interventional studies are needed to confirm the results.

The immune phenotype of perinatal anxiety

BACKGROUND

Immune dysregulation has been linked to both psychiatric illness and pregnancy morbidity, including perinatal depression, but little is known about the immune phenotype of perinatal anxiety. Here, we sought to identify the unique immune profile of antenatal anxiety.

MATERIALS AND METHODS

Pregnant women (n = 107) were followed prospectively at 2nd and 3rd trimesters (T2, T3) and 6 weeks postpartum (PP6). Each visit included a blood draw and psychological evaluation, with clinical anxiety assessed using the Spielberg State-Trait Anxiety Scale. We enrolled both healthy controls and participants with anxiety alone; those with comorbid depression were excluded. Multiplex cytokine assays and flow cytometry were used to examine the association of anxiety symptoms with secreted immune markers and PBMC-derived immune cells.

RESULTS

K cluster means revealed three clusters of anxiety symptomatology; due to low numbers in the highest severity anxiety group, these were collapsed into two groups: Non-Anxiety and Anxiety. Principal components analysis revealed two distinct clusters of cytokine secretion including one cluster that consisted of many innate immune cytokines and differed between groups. Compared to women in the Non-Anxiety group, women in the Anxiety group had lower levels of cytokine expression during pregnancy and an increase in levels into the postpartum, whereas Non-Anxiety women experienced a time-dependent decline. Immune cell populations also differed between our two groups, with the Anxiety group showing a decrease in the ratio of B cells to T cells from pregnancy to postpartum, whereas the Non-Anxiety women showed an increase in this ratio over time. Women in the Anxiety group also demonstrated an increased ratio of cytotoxic to helper T cells throughout pregnancy, a modest increase in the Th1:Th2 ratio across pregnancy, and a lower ratio of Th17:T_REG cells in the postpartum as compared with Non-Anxiety women.

CONCLUSION

These data suggest that the immune response throughout the antenatal period differs for women with anxiety symptoms compared to those without, suggestive of a unique immune phenotype of perinatal anxiety.

Sex-specific association of high maternal psychological stress during pregnancy on newborn birthweight

Birthweight is an important predictor of newborn health and has been linked to maternal psychological stress during pregnancy. However, it is unclear whether prenatal stress affects birthweight similarly for both male and female infants. We used a well-established pregnancy cohort to investigate the impact of high maternal psychological stress during pregnancy on birthweight as a function of infant sex. Overall, 5702 mother-newborn pairs were analysed. Of these, 198 mothers reported high levels of stress using the Psychological Stress Measure (nine-items version; PSM-9). Maternal psychological stress was assessed between the 24^th and 28^th week of gestation and analyses were performed jointly and independently as a function of neonatal sex (separate analyses for male and female infants). Newborns exposed to high maternal psychological stress during pregnancy (a score above 26 measured using the PSM-9 questionnaire, corresponding to >97.5^th percentile) were compared to newborns of mothers who reported lower stress. ANCOVAs revealed that high levels of maternal stress during pregnancy were linked to infant birthweight as a function of infant sex. Male infants of mothers who reported high levels of stress had a greater birthweight whereas female infants had a lower birthweight under the same conditions, in comparison to mothers who did not report greater levels of stress. Although the effect size is small, these results underline the possibility that male and female fetuses may use different strategies when adapting to maternal adversity and highlight the need to consider infant sex as a moderator of the association between maternal psychological stress during pregnancy and infant birthweight.

Association between fetoplacental Doppler results, placental pathology, and angiogenic factors among pregnant women with anxiety

OBJECTIVE

This study aimed to evaluate whether state and trait anxiety among pregnant women were associated with fetoplacental Doppler findings, abnormal placental pathology, and placental angiogenic factors.

MATERIALS AND METHODS

A total of 102 pregnant women at 32-35 gestational weeks were recruited and examined prospectively. State and trait anxiety were measured using the State-Trait Anxiety Inventory. Using Doppler ultrasound, pulsatility index (PI) of the umbilical artery (UA), middle cerebral artery (MCA), and uterine artery (UtA) and cerebroplacental ratio (CPR) were determined. Doppler parameters were converted into multiples of the median (MoM). Abnormal placental pathology was classified into 2 groups: vascular underperfusion (VU) and histological chorioamnionitis (HCA). Immunohistochemical analysis was performed to examine placental cells staining positive for placental growth factor (PLGF) and hypoxia-inducible factor-1-α (HIF-1α), which are markers for angiogenesis and hypoxic status, respectively.

RESULTS

Women with high state anxiety scores had low MCA-PI MoM and CPR MoM, while those with high trait anxiety scores had low MCA-PI MoM. VU was associated with a higher incidence of high trait anxiety scores, and HCA was associated with a higher incidence of high state and trait anxiety scores. Regression analysis showed a relationship between maternal state anxiety on MCA-PI MoM and HCA after controlling for covariates. Maternal trait anxiety exhibited relationships with VU and HCA after adjustment.

CONCLUSION

Our results demonstrated that maternal anxiety is associated with altered fetal cerebral blood flow and abnormal placental pathology but is not associated with uteroplacental insufficiency and placental angiogenic factors.

Association between antenatal maternal anxiety and fetal middle cerebral artery Doppler depends on fetal gender

Objective: Several studies have demonstrated that antenatal maternal anxiety (AMA) during pregnancy is associated with an increased risk of abnormal fetal Doppler parameters and adverse perinatal outcomes. Despite these studies, the evidence of the association between them remains inconclusive due in part to the methodological limitations of existing studies. Hence, in the present study, we established strict criteria and excluded patients who may have moderate or confounding variables to investigate the relationship between AMA and fetal Doppler findings and adverse perinatal outcomes.Methods: This was a cross-sectional study of 160 healthy nulliparous pregnant women (gestational age 31-33 weeks) with uncomplicated obstetric histories, who underwent Doppler flow studies on uterine, umbilical and fetal middle cerebral artery (MCA). Maternal anxiety was measured by STAI-State and STAI-Trait inventory.Results: Statistical analyses revealed that STAI-Trait anxiety was associated with lower MCA pulsatility index at 31-33 weeks gestational age and lower birth weight for the female fetus. There were no significant differences in the birth weight of boys of mothers with high anxiety and without high anxiety.Conclusions: The adaptation of the fetus to this hostile environment as AMA differs by gender. Adaptation for the female fetus means the "brain sparing effect" and reduced birth weight. The findings emphasize the potential importance of maternal psychological wellbeing during pregnancy for fetal development.

Investigation of the effect of training attachment behaviors to pregnant mothers on some physical indicators of their infants from birth to three months based on the separation of male and female infants

BACKGROUND

Maternal attachment to the fetus during pregnancy improves infant's growth and development and is an important criterion for public health. The aim is to investigate the effect of training attachment behaviors to pregnant women on some growth health indicators of infants.

METHODS

This is a clinical trial with convenience sampling which was conducted on 190 pregnant women in Hafez Hospital in Shiraz who randomly classified into intervention and control groups. For the intervention group, 6 sessions of 90-min classes were held. After delivery, both groups were compared in terms of physical growth (weight, height, head circumference) at birth, one and three months after birth. The data were analyzed using repeated Measurement.

RESULTS

Weight increase in female infants in the intervention group compared to the control group was significant at birth (p = 0.016), one month (p = 0.010) and three months after birth (p = 0.014). Height increase in female infants in the intervention group compared to the control group was significant at birth (p = 0.025), one month (p < 0.001) and three months after birth (p = 0.009). Male gender was not statistically significant in any age group but it increased the size of the head circumference of three-month-old infants.

CONCLUSION

Training of attachment skills to mothers improves height and weight of female infants in three steps. The average index for boys in the intervention group was higher than that of control group, but it was not significant.

Association between illness perception and health-related quality of life in patients with preexisting premature coronary artery disease

OBJECTIVES

Illness perception in younger age differs from that in older age. We aimed to examine the association between illness perception and health-related quality of life (HRQoL) in patients with premature coronary artery disease (CAD).

METHODS

In a cross-sectional design, between November 2016 and September 2017, a total of 779 adults (52.5% female) with premature CAD (diagnosed in men aged ≤ 45 y and women aged ≤ 55 y) completed the Beck Depression Inventory-II, the Beck Anxiety Inventory, the Brief Illness Perception, and the Short-Form Health Survey 36 questionnaires in an outpatient clinic 8 years after the diagnosis.

RESULTS

The patients were treated with coronary artery bypass graft surgery (24.6%), percutaneous coronary intervention (39.5%), and medical treatment (35.8%). The cognitive, emotional, and comprehension aspects of illness perception had significant associations with both physical and mental health in univariable analysis (all Ps < 0.001). After adjustments for potential confounding factors, higher cognitive perception was independently associated with greater physical health [OR = 4.13, Confidence interval (CI): 3.53-4.72] and mental health (OR = 3.17, CI: 2.57-3.77). Additionally, emotional perception was also directly associated with higher physical (OR = 1.62, CI: 1.17-2.06) and mental (OR = 1.52, CI: 1.07-1.96) health; all Ps < 0.001.

CONCLUSIONS

Of the 3 different aspects of illness perception, cognitive perception appeared to have the greatest influence on HRQoL, either physical or mental health. Further studies are needed to investigate whether cognitive interventions can improve HRQoL in premature CAD patients and, thus, their outcome.

Placental FKBP51 mediates a link between second trimester maternal anxiety and birthweight in female infants

Prenatal distress is associated with adverse outcomes in affected offspring. Alterations in placental glucocorticoid signalling and subsequent foetal overexposure to glucocorticoids have been implicated as an underlying mechanism. Infant sex is emerging as an important factor in disease susceptibility. This study aimed to examine the effects of maternal distress across pregnancy on birth outcomes and placental glucocorticoid genes in a sex-dependent manner. Participants completed psychological distress questionnaires throughout pregnancy. Placental HSD11B2, NR3C1 and FKBP51 were analysed by real time PCR and cortisol was measured in new-born hair. Second trimester stress was negatively correlated with birthweight in males and positively correlated with placental NR3C1 mRNA in females. Second trimester anxiety was negatively correlated with birthweight and placental FKBP51 mRNA in females. In mediation analysis, placental FKBP51 mRNA expression was found to mediate the link between prenatal anxiety and birthweight. New-born cortisol was negatively correlated with second trimester anxiety and positively correlated with female placental FKBP51 mRNA levels. Again, FKBP51 mRNA was found to mediate the link between anxiety and new-born cortisol. These results highlight a role for FKBP51 in the placental response to prenatal distress in females. The precise role that placental FKBP51 has in foetal and infant development has not been extensively studied and warrants further investigations.

Illness Perceptions in Patients with Premature Coronary Artery Disease: A Sex-Based Analysis 8 Years After the Diagnosis

To assess illness perceptions in patients with premature atherosclerotic coronary artery disease (CAD), 717 adults with premature CAD (diagnosis of CAD in men age < 45 years and women age < 55 years) completed sociodemographic indices, the Beck's Depression Inventory-II, Beck Anxiety Inventory and the Brief Illness Perceptions 8 years after the diagnosis. Mean age was 49.59 ± 3.57 years for men and 57.72 ± 4.90 years for women at the time of study. Both sexes were treated through coronary artery bypass graft surgery, percutaneous coronary intervention, or medical treatment. Depressive and anxiety symptoms were significantly more prevalent among women. Generally, the patients believed that their disease was chronic and well controlled and that it had no considerable negative impact on their routine life. Overall, patients had a low concern about their illness. Women had a more negative perception of their disease than did men which may indicate their need for higher psychological support.

Obstetrical and neonatal outcomes after benzodiazepine exposure during pregnancy: Results from a prospective registry of women with psychiatric disorders

OBJECTIVE

The goal of this analysis was to examine the effect of benzodiazepine use during pregnancy on maternal and neonatal outcomes in a cohort of women with psychiatric disorders.

METHODS

794 evaluable women from the Massachusetts General Hospital National Pregnancy Registry for Psychiatric Medications were followed across pregnancy (N = 144 exposed to benzodiazepines and N = 650 unexposed). Data obtained through maternal report and medical records included maternal outcomes (cesarean section, preeclampsia) and neonatal outcomes (birth weight, breathing difficulty, feeding difficulty, head circumference, 5-minute Apgar score, muscular and/or extrapyramidal symptoms, NICU admission, prematurity).

RESULTS

In adjusted analyses, infants exposed to benzodiazepines in utero were more likely to be admitted to the NICU (OR: 2.02, 95% CI: 1.11, 3.66) and to have small head circumferences (OR: 3.89, 95% CI: 1.25, 12.03) compared to unexposed infants. Other neonatal adverse effects such as respiratory distress or muscular symptoms including hypotonia were not observed. There were no significant differences in adverse obstetrical outcomes.

CONCLUSIONS

Infants exposed to benzodiazepines during pregnancy had an increased risk of NICU admissions and small head circumferences. Confounding from psychiatric symptoms and other variables cannot be ruled out as contributors to these findings.

Relation between maternal antenatal anxiety and infants' weight depends on infants' sex: A longitudinal study from late gestation to 1-month post birth

OBJECTIVE

To test for gender-differences in the relation between mothers' antenatal anxiety and infants' body weight during gestation, at birth, and at 1-month of age.

METHODS

Two hundred and twelve randomly-recruited women were divided into two groups: Controls (n=105) and Anxious Group (n=107) based on a standard cut-off of the Beck Anxiety Inventory. Outcome measures were Fetal Weight derived from biometrics obtained from an ultrasound scan in the 3rd trimester and infants' weight at birth and at 1-month of age, both obtained from medical records.

RESULTS

Multivariate analyses showed main effects of Gender on infants' birth weight (P=.001) and on infants' weight at 1-month of age (P=.004), but no main effects of Anxiety Group at any time-point. Gender x Anxiety Group interactions at all three time points (Fetal weight: P=.05; Birth weight: P=.03; 1-month of age: P=.10) reflected gender differences (males>females) among infants in the anxious group, but not among controls. Distinct trends regarding same sex comparisons across groups (Control vs. Anxiety) were in line with predictions (male controls<male anxious; female controls>females anxious). Controlling for Postpartum Anxiety and Antenatal and Postpartum Depression in the models did not affect primary results.

CONCLUSION

Gender differences in fetal and birth weight were more substantial among infants of anxious mothers than among controls due to the seemingly accelerated growth of "anxious" males and the diminution of weight among "anxious" females.
