Pregnancy and birth complications and long-term maternal mental health outcomes: A systematic review and meta-analysis

BACKGROUND

Few studies have examined the associations between pregnancy and birth complications and long-term (>12 months) maternal mental health outcomes.

OBJECTIVES

To review the published literature on pregnancy and birth complications and long-term maternal mental health outcomes.

SEARCH STRATEGY

Systematic search of Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica Database (Embase), PsycInfo®, PubMed® and Web of Science from inception until August 2022.

SELECTION CRITERIA

Three reviewers independently reviewed titles, abstracts and full texts.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and appraised study quality. Random-effects meta-analyses were used to calculate pooled estimates. The Meta-analyses of Observational Studies in Epidemiology (MOOSE) guidelines were followed. The protocol was prospectively registered on the International Prospective Register of Systematic Reviews (PROSPERO: CRD42022359017).

MAIN RESULTS

Of the 16 310 articles identified, 33 studies were included (3 973 631 participants). Termination of pregnancy was associated with depression (pooled adjusted odds ratio, aOR 1.49, 95% CI 1.20-1.83) and anxiety disorder (pooled aOR 1.43, 95% CI 1.20-1.71). Miscarriage was associated with depression (pooled aOR 1.97, 95% CI 1.38-2.82) and anxiety disorder (pooled aOR 1.24, 95% CI 1.11-1.39). Sensitivity analyses excluding early pregnancy loss and termination reported similar results. Preterm birth was associated with depression (pooled aOR 1.37, 95% CI 1.32-1.42), anxiety disorder (pooled aOR 0.97, 95% CI 0.41-2.27) and post-traumatic stress disorder (PTSD) (pooled aOR 1.75, 95% CI 0.52-5.89). Caesarean section was not significantly associated with PTSD (pooled aOR 2.51, 95% CI 0.75-8.37). There were few studies on other mental disorders and therefore it was not possible to perform meta-analyses.

CONCLUSIONS

Exposure to complications during pregnancy and birth increases the odds of long-term depression, anxiety disorder and PTSD.

Decision-making and future pregnancies after a positive fetal anomaly screen: A scoping review

AIMS AND OBJECTIVES

To examine and consolidate literature on the experiences and decision-making of parents following a screen positive result for a potential fetal anomaly and/or diagnosis of an actual anomaly in a previous pregnancy.

BACKGROUND

Prenatal screening consists of any diagnostic modality that is aimed at acquiring information about a fetus or an embryo; however, the entire process is highly stressful for parents, especially if there was a previous screen positive result, but no abnormality was detected in the final result.

METHODS

Eight electronic databases (PubMed, Embase, CINAHL, PsycINFO, Scopus, Web of Science, ProQuest Theses and Dissertations and ClinicalTrials.gov) were searched from each database's inception until February 2022. This scoping review was guided by Arksey and O'Malley's framework and was reported in accordance with the PRISMA-ScR checklist. Braun and Clarke's thematic analysis framework was utilised.

RESULTS

Thirty-one studies were eligible for inclusion. Two main themes (reliving the fear while maintaining hope, and bridging the past and future pregnancies) and six subthemes were identified.

CONCLUSIONS

A fetal anomaly diagnosis in pregnancy had a mixed impact on the attitudes of parents toward a future pregnancy. Some parents were fearful of reliving a traumatic experience, while others were determined to have a healthy child and grow their family. Parents generally expressed a greater preference for non-invasive over invasive prenatal testing due to the procedural risks involved.

RELEVANCE TO CLINICAL PRACTICE

There is a need for healthcare professionals to provide psychosocial and emotional support to parents so that they can achieve resolution for their previous pregnancy. Healthcare professionals' ability to provide informational support also enables these parents to make informed decision and understand their reproductive outcomes. Additionally, healthcare administration and policymakers should reconsider current neonatal or pregnancy loss bereavement guidelines to improve the inclusivity of fathers.

Effects of maternal pre-pregnancy body mass index and gestational weight gain on antenatal mental disorders in China: a prospective study

BACKGROUND

Maternal obesity is the most common medical condition among women of reproductive age worldwide. The pre-pregnancy body mass index and gestational weight gain have been suggested to be associated with maternal mental disorders. This study aimed to investigate the effects of the pre-pregnancy body mass index and gestational weight gain on antenatal depression, stress, and anxiety.

METHODS

In total, 4,890 pregnant women were enrolled in the present study, which is based on an ongoing prospective cohort study. We used self-reported pre-pregnancy weights and the last weights measured prior to delivery (using professional instruments) to calculate the pre-pregnancy body mass index and gestational weight gain. The questionnaires used included the Center for Epidemiologic Studies Depression Scale (CES-D), Self-Rating Anxiety Scale (SAS), and 10-item version of the Perceived Stress Scale (PSS-10). We used Pearson product-moment correlation and multivariable logistic regression models to examine the impact of the pre-pregnancy body mass index and gestational weight gain on different maternal mental disorders.

RESULTS

After adjusting for conception, annual household income, occupation, education, smoking status, and drinking status, excessive gestational weight gain during pregnancy was associated with a greater chance of anxiety symptoms in the entire sample (adjusted model: odds ratio = 1.479, 95% confidence interval = 1.128, 1.938) and especially in women with a normal body mass index (adjusted model: odds ratio = 1.668, 95% confidence interval = 1.209, 2.302). However, the relationship between the maternal pre-pregnancy body mass index and mental health was not significant.

CONCLUSION

Pregnant women with a normal pre-pregnancy body mass index had a greater chance of experiencing anxiety symptoms before delivery if gestational weight gain was excessive; however, its effects on depression or stress symptoms were not observed. The maternal pre-pregnancy body mass index may not be independently associated with maternal mental disorders.

Impact of expectant mother's knowledge level about fetal anomaly scan on their state anxiety prior to antenatal ultrasound screening

OBJECTIVE

We aimed to investigate the role of expectant mothers' background antenatal ultrasound knowledge on their state anxiety when they apply for the ultrasound examination.

MATERIALS AND METHODS

A cross-sectional study was conducted in perinatology outpatient clinic of a university hospital. Expectant mothers who applied for the first trimester ultrasound scan and second trimester anomaly scan were recruited to the study. A self-report form was applied to participants to assess the sociodemographic characteristics, obstetric history, knowledge and attitudes toward antenatal ultrasound. Expectant mothers' state anxiety prior to ultrasound scan was measured with the state sub-scale of State-Trait Anxiety Inventory.

RESULTS

A total of 500 expectant mothers (220 in the first trimester and 280 in the second trimester) were included to the study. We found a negative correlation between the participants' age and state anxiety level (r = -0.118, p < .01). Also, participants' education level had a significant effect on their state anxiety level (F (2, 497)=5.91, p < .01). Participant's age significantly predicted lower state anxiety level (β = -0.10, t = -2.09, p < .05). We did not find any significant relationship between the mean knowledge level of mothers and state anxiety levels of mothers (r = -0.07, p > .05).

CONCLUSION

Age was the only affecting factor on anxiety levels before ultrasound scan in pregnant participants. There was no significant effect of background knowledge on state anxiety.

Biological, Behavioral and Physiological Consequences of Drug-Induced Pregnancy Termination at First-Trimester Human Equivalent in an Animal Model

Given the significant physiological changes that take place during and resulting from pregnancy, as well as the relative absence of such information in relation to pregnancy termination, this study investigated the potential for developing a valid animal model to objectively assess the biological, physiological and behavioral consequences of drug-induced pregnancy termination. Female Long-Evans rats were divided into four groups (n = 19-21/group), controlling for drug [mifepristone (50 mg/kg/3 ml, i.g.)/misoprostol (0.3 mg/kg/ml, i.g.) or vehicle (1% Carboxymethylcellulose Sodium/0.2% Tween® 80 suspension, i.g.)] and pregnancy. Drug administration took place on days 12-14 of gestation (days 28-40 human gestational equivalent). Vehicle was administered to the controls on the same days. Parameters measured included rat body weight, food intake, vaginal impedance, sucrose consumption/preference, locomotor activity, forced swim test, and home-cage activity. At the termination of the study, rats were deeply anesthetized using urethane, and blood, brain, and liver were collected for biochemical analysis. Following drug/vehicle administration, only the pregnancy termination group (pregnant, drug) displayed a significant decrease in body weight, food intake, locomotor activity-related behaviors and home-cage activity relative to the control group (non-pregnant, vehicle). Additionally, the pregnancy termination group was the only group that displayed a significant reduction in sucrose consumption/preference during Treatment Week relative to Pre-Treatment Week. Vaginal impedance did not significantly decrease over time in parous rats in contrast to all other groups, including the rats in the pregnancy termination group. Biochemical analysis indicated putative drug- and pregnancy-specific influences on oxidative balance. Regression analysis indicated that pregnancy termination was a predictor variable for body weight, food intake and all locomotor activity parameters measured. Moreover, pertaining to body weight and food intake, the pregnancy termination group displayed significant changes, which were not present in a group of naturally miscarrying rats following pregnancy loss. Overall, our results appear to suggest negative biological and behavioral effects following pregnancy termination, that appear to also be distinct from natural miscarriage, and potential benefits of parity pertaining to fecundity. Thus, our findings indicate the importance for further objective investigation of the physiological and behavioral consequences of medical abortion, in order to provide further insight into the potential implications in humans.

The abortion and mental health controversy: A comprehensive literature review of common ground agreements, disagreements, actionable recommendations, and research opportunities

The abortion and mental health controversy is driven by two different perspectives regarding how best to interpret accepted facts. When interpreting the data, abortion and mental health proponents are inclined to emphasize risks associated with abortion, whereas abortion and mental health minimalists emphasize pre-existing risk factors as the primary explanation for the correlations with more negative outcomes. Still, both sides agree that (a) abortion is consistently associated with elevated rates of mental illness compared to women without a history of abortion; (b) the abortion experience directly contributes to mental health problems for at least some women; (c) there are risk factors, such as pre-existing mental illness, that identify women at greatest risk of mental health problems after an abortion; and (d) it is impossible to conduct research in this field in a manner that can definitively identify the extent to which any mental illnesses following abortion can be reliably attributed to abortion in and of itself. The areas of disagreement, which are more nuanced, are addressed at length. Obstacles in the way of research and further consensus include (a) multiple pathways for abortion and mental health risks, (b) concurrent positive and negative reactions, (c) indeterminate time frames and degrees of reactions, (d) poorly defined terms, (e) multiple factors of causation, and (f) inherent preconceptions based on ideology and disproportionate exposure to different types of women. Recommendations for collaboration include (a) mixed research teams, (b) co-design of national longitudinal prospective studies accessible to any researcher, (c) better adherence to data sharing and re-analysis standards, and (d) attention to a broader list of research questions.

Risk factors for antenatal anxiety: A systematic review of the literature

BACKGROUND

Given the prevalence of antenatal anxiety and its consistent associations with adverse pregnancy and child outcomes, early detection and management of anxiety are essential.

OBJECTIVE

The aim was to identify risk factors for anxiety among pregnant women by systematically reviewing original research.

METHODS

Cross-sectional, case-control and cohort studies that examined associations between antenatal anxiety and at least one potential risk factor prospectively or retrospectively and measured anxiety independent from other mental health conditions were included. Studies rated strong/moderate in methodological quality appraisal were used to synthesise the evidence.

RESULTS

Factors associated with greater risk of anxiety included previous pregnancy loss, medical complications, childhood abuse, intimate partner violence, denial/acceptance coping styles, personality traits, inadequate social support, history of mental health problems, high perceived stress and adverse life events.

CONCLUSIONS

Several risk factors identified in this review are detectable in routine prenatal care visits (e.g. previous pregnancy loss, pregnancy complications), potentially modifiable (e.g. coping styles, social support, partner factors) and can be identified prior to pregnancy (e.g. psychosocial factors), underlining the significance of pre-conception mental health screening.

Assigning Clinical Significance and Symptom Severity Using the Zung Scales: Levels of Misclassification Arising from Confusion between Index and Raw Scores

BACKGROUND

The Zung Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) are two norm-referenced scales commonly used to identify the presence of depression and anxiety in clinical research. Unfortunately, several researchers have mistakenly applied index score criteria to raw scores when assigning clinical significance and symptom severity ratings. This study examined the extent of this problem.

METHOD

102 papers published over the six-year period from 2010 to 2015 were used to establish two convenience samples of 60 usages of each Zung scale.

RESULTS

In those papers where cut-off scores were used (i.e., 45/60 for SDS and 40/60 for SAS), up to 51% of SDS and 45% of SAS papers involved the incorrect application of index score criteria to raw scores. Inconsistencies were also noted in the severity ranges and cut-off scores used.

CONCLUSIONS

A large percentage of publications involving the Zung SDS and SAS scales are using incorrect criteria for the classification of clinically significant symptoms of depression and anxiety. The most common error-applying index score criteria to raw scores-produces a substantial elevation of the cut-off points for significance. Given the continuing usage of these scales, it is important that these inconsistencies be highlighted and resolved.

The presence of anxiety, depression and stress in women and their partners during pregnancies following perinatal loss: A meta-analysis

BACKGROUND

Research indicates perinatal loss is associated with anxiety, depression and stress in women and partners during subsequent pregnancies. However, there are no robust estimates of anxiety, depression and stress for this group. We meta-analytically estimated rates of anxiety, depression and stress in pregnant women and their partners during pregnancies after previous perinatal loss.

METHODS

Databases (Medline, PsychInfo, Embase, Cinahl Plus) and grey literature were searched from 1995 through to May 2016. Search terms included: depression, anxiety, or stress with perinatal loss (miscarry*, perinatal death, spontaneous abortion, fetal death, stillbirth, intrauterine death, TOPFA) and subsequent pregnancy. Case-controlled, English-language studies using validated measures of anxiety, depression or stress in women or partners during pregnancy following perinatal loss were included. Data for effect sizes, study and demographic data were extracted.

RESULTS

We identified nineteen studies representing n = 5114 women with previous loss; n = 30,272 controls; n = 106 partners with previous perinatal loss; and n = 91 control men. Random effects modelling demonstrated significant effects of perinatal loss on anxiety (d = 0.69, 95% CI = 0.41-0.97) and depression (d = 0.22, 95% CI = 0.15-0.30) in women; but no effect on stress (d = - 0.002, 95% CI = - 0.0639 to 0.0605).

LIMITATIONS

This study was limited by the quality of available studies, underpowered moderator analyses and an inability to examine additional covariates. Insufficient data were available to generate reliable effects for psychological distress in partners.

CONCLUSIONS

Our findings confirm elevated anxiety and depression levels during pregnancies following perinatal loss. Further research on predictors of distress in women and their partners is required.

Previous pregnancy outcomes and subsequent pregnancy anxiety in a Quebec prospective cohort

INTRODUCTION

Pregnancy anxiety is an important psychosocial risk factor that may be more strongly associated with adverse birth outcomes than other measures of stress. Better understanding of the upstream predictors and causes of pregnancy anxiety could help to identify high-risk women for adverse maternal and infant outcomes. The objective of the present study was to measure the associations between five past pregnancy outcomes (live preterm birth (PTB), live term birth, miscarriage at <20 weeks, stillbirth at ≥20 weeks, and elective abortion) and pregnancy anxiety at three trimesters in a subsequent pregnancy.

METHODS

Analyses were conducted using data from the 3D Cohort Study, a Canadian birth cohort. Data on maternal demographic characteristics and pregnancy history for each known previous pregnancy were collected via interviewer-administered questionnaires at study entry. Pregnancy anxiety for the index study pregnancy was measured prospectively by self-administered questionnaire following three prenatal study visits.

RESULTS

Of 2366 participants in the 3D Study, 1505 had at least one previous pregnancy. In linear regression analyses with adjustment for confounding variables, prior live term birth was associated with lower pregnancy anxiety in all three trimesters, whereas prior miscarriage was significantly associated with higher pregnancy anxiety in the first trimester. Prior stillbirth was associated with greater pregnancy anxiety in the third trimester. Prior elective abortion was significantly associated with higher pregnancy anxiety scores in the first and second trimesters, with an association of similar magnitude observed in the third trimester.

DISCUSSION

Our findings suggest that the outcomes of previous pregnancies should be incorporated, along with demographic and psychosocial characteristics, into conceptual models framing pregnancy anxiety.

Effects of prenatal maternal mental distress on birth outcomes

BACKGROUND

Adverse effects of maternal mental distress during pregnancy have been extensively investigated, but the impact of prenatal maternal mental distress at various time periods during pregnancy on birth outcomes is rarely discussed. By understanding the relationship between maternal mental distress and unfavourable birth outcomes throughout pregnancy, appropriate evidence-based preventative care or intervention may be adopted in a timely manner.

AIM

This study intended to investigate the effects of maternal stress, anxiety, and depressive symptoms across pregnancy on preterm birth and low birth weight.

METHODS

With a prospective longitudinal design, this study used the 10-item Perceived Stress Scale, Center for Epidemiologic Studies Depression Scale, and Zung Self-reported Anxiety Scale to investigate 197 participants who, at greater than 24 gestational weeks, completed the self-administered questionnaires during regular checkups in a hospital in southern Taiwan. Descriptive statistics, Mann-Whitney U test/Kruskal-Wallis test, and hierarchical logistic regression were applied for data analysis.

FINDINGS

The study found that anxiety and depressive symptoms at 25-29 gestational weeks could predict preterm birth, and that anxiety at greater than 30 gestational weeks was able to predict low birthweight. However, stress was not able to predict any kind of negative birth outcomes.

CONCLUSION

Adverse birth outcomes were somewhat predictable by maternal mental distress; therefore, we suggested that prenatal visits incorporate psychological assessment for early detection and management to prevent possible adverse birth outcomes.

Acute Psychotic Symptoms due to Benzydamine Hydrochloride Abuse with Alcohol

Benzydamine hydrochloride is a locally acting nonsteroidal anti-inflammatory drug. Benzydamine hydrochloride overdose can cause stimulation of central nervous system, hallucinations, and psychosis. We presented a young man with psychotic symptoms due to benzydamine hydrochloride abuse. He received a total dose of 1000 mg benzydamine hydrochloride with alcohol for its hallucinative effects. Misuse of benzydamine hydrochloride must be considered in differential diagnosis of first-episode psychosis and physicians should consider possibility of abuse in prescribing.
