Anxiety among fathers during the prenatal and postpartum period: a meta-analysis

A Systematic Review and Meta-analysis: Paternal Anxiety and the Emotional and Behavioral Outcomes in Their Offspring

OBJECTIVE

Anxiety disorders are highly prevalent worldwide; however, the literature lacks a meta-analytic quantification of the risk posed by fathers' anxiety for offspring development. This systematic review and meta-analysis aimed to provide a comprehensive estimate of the magnitude of the association between paternal anxiety and emotional and behavioral problems of offspring.

METHOD

In February 2022, Web of Science, Ovid (Embase, MEDLINE, PsycINFO), Trip Database, and ProQuest were searched to identify all quantitative studies that measured anxiety in fathers and emotional and/or behavioral outcomes in offspring. No limits were set for offspring age, publication language, or publication year. Summary estimates were extracted from the primary studies. Meta-analytic random-effects 3-level models were used to calculate correlation coefficients. Quality was assessed using the Newcastle-Ottawa Scale. The study protocol was preregistered with PROSPERO (CRD42022311501) and adhered to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) reporting guidelines.

RESULTS

Of 11,746 records identified, 98 were included in the meta-analysis. Small but significant associations were found between paternal anxiety and offspring emotional and behavioral problems overall (r = 0.16, 95% CI [0.13, 0.19]) and behavioral (r = 0.19, 95% CI [0.13, 0.24]), emotional (r = 0.15, 95% CI [0.12, 0.18]), anxiety (r = 0.13, 95% CI [0.11, 0.16]), and depression (r = 0.13, 95% CI [0.03, 0.23]) problems. Some significant moderators were identified.

CONCLUSION

Paternal mental health is associated with offspring development, and the offspring of fathers with anxiety symptoms or disorders are at increased risk of negative emotional and behavioral outcomes, in line with the principles of multifinality and pleiotropy. The substantial heterogeneity among studies and the overrepresentation of White European American groups in this literature highlight the need for further research.

Improving parental mental health in the perinatal period: A review and analysis of quality improvement initiatives

Parental mental health is an essential sixth vital sign that, when taken into consideration, allows clinicians to improve clinical outcomes for both parents and infants. Although standards exist for screening, referral, and treatment for perinatal mood and anxiety disorders (PMADs), they are not reliably done in practice, and even when addressed, interventions are often minimal in scope. Quality improvement methodology can accelerate the implementation of interventions to address PMADs, but hurdles exist, and systems are not well designed, particularly in pediatric inpatient facilities. In this article, we review the effect of PMADs on parents and their infants and identify quality improvement interventions that can increase screening and referral to treatment of parents experiencing PMADs.

Postpartum Mental Health and Perceptions of Discrimination Among Asian Fathers During the COVID-19 Pandemic

PURPOSE

The purpose of this study was twofold: (1) to examine the prevalence of postpartum depression and anxiety symptomatology among fathers of Asian descent living in North America during the COVID-19 pandemic, and (2) to identify the occurrences of online racial discrimination.

STUDY DESIGN AND METHODS

Using a cross-sectional design and convenience sampling methods, we recruited fathers online via social media sites (Facebook, Instagram) between March 12 and July 31, 2022. The Edinburgh Postnatal Depression Scale, General Anxiety Scale, and the Online Victimization Scale assessed mental health well-being and discrimination outcomes. Data were analyzed using descriptive statistics, two sample t-test, chi-square test of independence, and Pearson's correlation analysis.

RESULTS

Our sample included 61 fathers within 6 months postpartum living in the United States and Canada. Participants were on average 34 years old, married, and represented 17 Asian ethnic groups, including Asian Indian (41%), Filipino (11.3%), and Korean (8.1%). One-third of our participants (31.1%, n = 19) were at high risk of developing postpartum depression and scores of three (4.9%) fathers indicated they had clinically significant anxiety. Overall, 26.3% reported experiencing direct online racial discrimination and 65% reported occurrences of indirect online racial discrimination.

CLINICAL IMPLICATIONS

There was a high rate of depressive symptoms and occurrences of online racial discrimination among fathers of Asian descent living in North America. These rates are higher than the general perinatal population and further research is warranted to examine risk factors and preventive strategies among this unique paternal ethnic group.

Supporting families with complex early parenting needs through a virtual residential parenting service: An investigation of outcomes, facilitators and barriers

AIM

To investigate clients' perspectives about outcomes of a telehealth residential unit (RU) program for families experiencing complex early parenting issues, and to explore facilitators and barriers to positive client outcomes.

DESIGN

Qualitative study using semi-structured interviews.

METHODS

Semi-structured interviews were conducted with mothers (n = 18) admitted to a telehealth RU program. Interview transcripts were analysed using thematic analysis.

RESULTS

Mothers reported short-term improvements in their child's presenting issues (e.g. feeding to sleep, night-time waking, co-sleeping), increased confidence and increased partner involvement. According to participants, program outcomes were facilitated by a positive parent-clinician relationship, the accessibility of clinicians and being able to take part in the program from their own home. Barriers included difficulties with technical equipment and connecting with the clinician overnight, and challenges with implementing strategies in the longer term.

CONCLUSION

This nurse-led telehealth program was viewed positively by parents and the study identified a number of areas for improvement.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

Telehealth early parenting programs provide an important way for parents to receive support with early child sleep, settling and feeding issues. Clinicians working in this area should focus on the development of positive parent-nurse relationships, enhancing communication and availability for parents during overnight periods and supporting parents to develop early parenting skills that will be applicable across the early childhood period.

IMPACT

The study is the first to address client experiences of a telehealth RU program. Facilitators and barriers identified will inform service improvements to the program going forward, and similar telehealth programs for families; to ensure benefits and service outcomes are maximised for parents for such a crucial service.

REPORTING METHOD

The Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines for qualitative research were followed.

Hostile sexism is related to worse mental health outcomes among fathers

OBJECTIVE

Transition to parenthood is a life-changing yet stressful event for both men and women. The present study aims to: (1) establish the incidence of prenatal paternal depression and anxiety in a sample of expectant fathers and (2) assess the relationship between sexist beliefs and mental health outcomes.

METHODS

We recruited expectant fathers (n = 100) who attended the Gynecology and Obstetrics Outpatient Clinic of Eskişehir Osmangazi University Hospital with their pregnant partners. Fathers completed the Hospital Anxiety and Depression Scale, the Multidimensional Scale of Perceived Social Support, and the Ambivalent Sexism Scale.

RESULTS

36% of expectant fathers reported depression, and 12% reported anxiety. Hostile sexism was correlated with depression (r = 0.303, p < 0.01), and anxiety (r = 0.228, p < 0.05). Benevolent sexism was not related to anxiety or depression (each, p > 0.05). Family social support (p = 0.004) and perceived financial satisfaction (p = 0.027) predicted anxiety, while family social support (p < 0.001) and perceived financial satisfaction (p = 0.036) predicted depression. Hostile sexism predicted both anxiety (B = 0.28, p = 0.004) and depression (B = 0.32, p < 0.001).

LIMITATIONS

Results may not show a causal relationship due to the study's cross-sectional design. We recruited participants in only one center. Our measures of anxiety and depression were purely psychometric.

CONCLUSIONS

Sexist beliefs may serve as environmental stressors among men in the perinatal period by increasing the masculine role stress. Future interventions to treat prenatal paternal depression may target sexism.

Factor structure of the Edinburgh Postnatal Depression Scale in a large population-based sample of fathers

BACKGROUND

Paternal perinatal distress is receiving increasing attention. The Edinburgh Postnatal Depression Scale (EPDS) is the predominant screening tool for paternal perinatal distress. Research using the large Avon Longitudinal Study of Parents and Children (ALSPAC) cohort demonstrated that a three-factor EPDS structure is appropriate among mothers, with anhedonia, anxiety and depression factors emerging consistently across perinatal timepoints.

METHOD

We employed confirmatory factor (CFA; n = 6170 to 9848) analysis to determine if this structure was appropriate for ALSPAC fathers, and the extent of invariance between mother and father groups.

RESULTS

At 18-weeks gestation, and 8-weeks, 8-months and 21-months postpartum, the three-factor model had consistently superior fit to other proposed models. Consistent with interpretation of a total distress score, factors were highly correlated. The model exhibited configural invariance in both the first (8-months) and second (21-months) post-partum years. Metric and scalar invariance were not supported, however, non-invariance was largely attributable to item 9 canvassing "crying".

LIMITATIONS

While the study employs a large cohort, the data collection in 1991 to 1992 in the United Kingdom may not account for the diverse gender roles, family structures and societal changes seen since that time.

CONCLUSIONS

Interpretation of the EPDS as representing perinatal distress, reflecting anhedonia, anxiety and depression aspects, is appropriate for mothers and fathers. The experience of distress has nuanced gender-based differences. Implications for EPDS interpretation and cut-off scores among fathers are discussed.

[Fathers, patients in mother and baby unit? Thinking about family-based approach in perinatal care]

BACKGROUND

The perinatal period is a psychic risk for fathers because of multiple overhauls. Fathers' place in perinatal medicine has evolved these last few years but continues to be poorly limited. These psychic difficulties are barely investigated and diagnosed in everyday medical practice. The prevalence of depressive episodes by new fathers was high in the most recent research studies. This thus is a public health problem with consequences on the family system both in the short and the long-term.

REVIEW

In the mother and baby unit, the father's psychiatric care is often secondary. But with societal modifications, there is the question of impact of separation between the father and the mother and the baby. With the family based approach, care by the father is indispensable for the care of the mother, baby, and the family's as a whole.

OBJECTIVE

In our mother and baby unit located in Paris, fathers were also hospitalized as patients. Therefore difficulties in the familial dynamic, between each member of the triad and mental health difficulties of fathers were able to be treated.

CONCLUSION

Following the hospitalization of a few triads with a positive evolution, a reflection process is now in progress.

Paternal bonding in pregnancy and early parenthood: a qualitative study in first-time fathers

The birth of an infant marks a period of profound change in first-time parents. Parental love and warmth, however, already begin to develop during pregnancy. Also for fathers, the development of bonding to the infant may be a unique process. The current qualitative study aimed to explore views and experiences of first-time fathers on the origins and development of paternal bonding during pregnancy and early childhood. In total, 30 in-depth semi-structured interviews were conducted with expectant fathers (second or third trimester of pregnancy; n = 10) and fathers of infants (0-6 months postpartum; n = 11) and toddlers (2-3 years of age; n = 9). Two major themes were uncovered from the data: feelings of bonding and facilitators of bonding. The first theme was supported with three subthemes: 1) from abstract to concrete, 2) positive emotions, and 3) uncertainties and worries. The second theme, facilitators of bonding, was supported with four subthemes: 1) experiencing the foetus, 2) meeting the child, 3) interaction, and 4) communication. Similar to previous studies, our results suggested that, in most fathers, paternal bonding originates in pregnancy and that it evolves over time. Seeing or feeling the child, both during pregnancy and postpartum, as well as interacting or communicating with the child, appears to facilitate fathers' feelings of bonding. Involving fathers in pregnancy, childbirth, and parenting may be essential for their bonding process.

The impact of paternal mental illness on child development: an umbrella review of systematic reviews and meta-analyses

Whilst there is growing evidence highlighting the importance of paternal mental illness (PMI) on child development, this relationship still remains under-studied and often over-looked. Considering the increasingly active role of fathers in their children's upbringing, a comprehensive overview of the impact of PMI on child development is overdue. This study aimed to combine and synthesise currently available evidence on the relationship between PMI and multiple domains of child development. Narrative synthesis of systematic reviews and meta-analyses on the relationship between PMI and child development (mental health and social, emotional, language, cognitive or adaptive behaviour), published between 1980 to December 2021, was conducted in line with PRISMA 2020 guidelines. Review quality was assessed based on AMSTAR-2 criteria and respective study confidence was interpreted in line with GRADE scoring. All relevant meta-analytic effect sizes were converted to odds ratios (OR) and grouped using a random effects model. Grouped meta-analyses saw PMI to have a significant, detrimental effect on all studied domains of child development [OR: 1.54; 95% CI (1.36-1.74)]. Subgroup analyses saw PMI affecting both internalising [OR: 1.62; 95% CI (1.27-2.08)] and externalising [OR: 1.63; 95% CI (1.28-2.08)] child behaviours to a similar extent. However, included reviews were of poor methodological quality, demonstrating either low or critically low confidence. These results show a consistent and influential effect of PMI on child development. The relationship between fathers' mental illness and child development warrants further investigation, as current research is limited in scope, particularly regarding cognitive domains of child development and non-affective PMI diagnoses.

Insights of Parents and Parents-To-Be in Using Chatbots to Improve Their Preconception, Pregnancy, and Postpartum Health: A Mixed Studies Review

INTRODUCTION

Chatbots, which are also known as conversational or virtual agents, are digital programs that can interact with humans using voice, text, or animation. They have shown promise in providing preconception, pregnancy, and postpartum care. This review aims to consolidate the insights of parents and parents-to-be in using chatbots to improve their preconception, pregnancy, and postpartum health.

METHODS

Seven electronic databases were searched from their inception dates until April 2022 (PubMed, Embase, CINAHL, PsycINFO, Web of Science, Scopus, and ProQuest Dissertations and Theses Global) for relevant studies. English language primary studies that were conducted on parents or parents-to-be aged ≥18 years old who had undergone interventions involving the use of any type of chatbot were included in this review. The quality of included studies was appraised using the Mixed Methods Appraisal Tool. A convergent qualitative synthesis design for mixed studies reviews was used to synthesize the findings, and results were thematically analyzed.

RESULTS

Fifteen studies met the inclusion criteria: quantitative (n = 11), qualitative (n = 1), and mixed method (n = 3). Three main themes were identified: (1) welcoming a new health resource, (2) obstacles blocking the way, and (3) moving toward a digital health era.

DISCUSSION

Parents and parents-to-be appreciated the informational, socioemotional, and psychological support provided by chatbots. Recommendations for technological improvements in the functionality of the chatbots were made that include training sessions for health care providers to familiarize them with this new digital technology. Multidisciplinary chatbot development teams could also be established to develop more comprehensive chatbot-delivered health programs for more diverse populations.

'Parentbot - A Digital healthcare Assistant (PDA)': A mobile application-based perinatal intervention for parents: Development study

OBJECTIVE

To describe the development procedure of a mobile application-based parenting support program with integrated chatbot features entitled Parentbot - a Digital healthcare Assistant (PDA) for multi-racial Singaporean parents across the perinatal period.

METHODS

The PDA development process was guided by the combined information systems research framework with design thinking modes, and Tuckman's model of team development. A user acceptability testing (UAT) process was conducted among 11 adults of child-bearing age. Feedback was obtained using a custom-made evaluation form and the 26-item User Experience Questionnaire.

RESULTS

The combined information systems research framework with design thinking modes helped researchers to successfully create a PDA prototype based on end-users' needs. Results from the UAT process indicated that the PDA provided participants with an overall positive user experience. Feedback gathered from UAT participants was used to enhance the PDA.

CONCLUSION

Although the effectiveness of the PDA in improving parental outcomes during the perinatal period is still being evaluated, this paper highlights the key details of developing a mobile application-based parenting intervention which future studies could learn from.

PRACTICE IMPLICATIONS

Having carefully planned timelines with margins of delays, extra funds to resolve technical issues, team cohesion, and an experienced leader can facilitate intervention development.

Prevalence of and factors associated with postnatal depression and anxiety among parents of preterm infants: A systematic review and meta-analysis

BACKGROUND

This study aimed to determine the prevalence of and factors associated with postpartum depression and anxiety among mothers and fathers of preterm infants and to examine the relationships between maternal and paternal symptoms.

METHODS

Six electronic databases were searched to identify eligible studies reporting parental depression and anxiety within 1 year postpartum. Data were extracted for a random-effects meta-analysis to estimate the prevalence with 95 % confidence intervals (CIs). Subgroup and meta-regression analyses were conducted to analyze associations between study characteristics and prevalence estimates.

RESULTS

In total, 79 studies were included. The meta-analysis of studies on mothers generated estimates of prevalence for depression (29.2 %, 95 % CI, 21.8 %-37.9 %) and anxiety (37.7 %, 95 % CI, 24.1 %-53.6 %). The meta-analysis of fathers indicated a pooled depression prevalence of 17.4 % (95 % CI, 12.5 %-23.8 %) and an anxiety estimate of 18.3 % (95 % CI, 8.1 %-36.3 %). Assessment time points and methods as well as the geographic continent in which the study was conducted were significant moderators of depression and anxiety. Significant inter-correlations were found between mothers' and fathers' depression and anxiety symptoms (p < 0.05).

LIMITATIONS

Limited data from specific geographic continents, including Africa and Asia.

CONCLUSIONS

Prevalence of depression and anxiety among preterm infants' parents was high, highlighting the need for early psychological screening and assessment. Further research is required to improve services that focus on parents' postpartum psychological needs in the family context.

Association of adolescent and young adult depression and anxiety with perinatal mental health in fathers: Findings from an Australian longitudinal study

The current study examined associations between preconception diagnoses of major depressive disorder (MDD) and anxiety disorders in adolescence and young adulthood and perinatal depression and anxiety symptoms in early fatherhood. In an Australian community cohort study of health and development, earlier history of MDD and anxiety disorders (extending back to adolescence) were assessed retrospectively in the third trimester of pregnancy via the Composite International Diagnostic Interview. Paternal perinatal depression and anxiety were then assessed prospectively over three timepoints (third trimester of pregnancy, 8 weeks and 12 months postpartum), using established cut-points on the Edinburgh Postnatal Depression Scale and the Depression Anxiety Stress Scales (anxiety subscale). Mixed-effects regression models examined risk associations between preconception diagnoses of MDD and anxiety disorders, and perinatal depression and anxiety symptoms at each timepoint, adjusting for socio-demographic factors and concurrent maternal mental health difficulties. The odds of clinically concerning levels of paternal perinatal depression and anxiety were 6-fold and 4-fold higher, respectively, in men with a preconception history of MDD. The odds of perinatal depression were 3-fold higher in men with a preconception history of an anxiety disorder. Less evidence was found for an association between preconception diagnoses of an anxiety disorder and perinatal anxiety in fathers. Interventions aimed at improving mental health in men during adolescence and young adulthood may promote continued psychological health in men during early fatherhood.

Effectiveness of mobile application-based perinatal interventions in improving parenting outcomes: A systematic review

Objective

Parents face many challenges during the perinatal period and are at risk for mental health issues, especially during the current coronavirus (COVID-19) pandemic. Mobile application-based interventions can help parents to improve their psychosocial well-being in a convenient and accessible manner. This review aims to examine the effectiveness of mobile application-based perinatal interventions in improving parenting self-efficacy, anxiety, and depression (primary outcomes), as well as stress, social support, and parent-child bonding (secondary outcomes) among parents.

Methods

Seven electronic databases (PubMed, Embase, CINAHL, PsycINFO, Web of Science, Scopus, and ProQuest Thesis and Dissertations) were searched from their respective inception dates until August 2021. The Cochrane Risk of Bias-2 tool was used to conduct quality appraisals. Results were narratively synthesized due to the high heterogeneity of intervention and participant types.

Findings

A total of 6164 articles were retrieved from the seven electronic databases and citation searching. After excluding duplicate records and irrelevant titles/abstracts, 105 full texts were examined. Full-text screening excluded another 93 articles, leaving 12 included studies in this review. All studies were rated as having some concerns or a high overall risk of bias. Mobile application-based interventions were found to be feasible and promising in improving parents’ overall well-being post-intervention during the perinatal period. Further research would be needed to determine their long-term effects.

Key conclusions and implications for practice

Parental well-being was shown to improve using the following intervention components: educational resources on perinatal and infant care, psychotherapy, and support from peers and healthcare professionals. Hence, future interventions could aim to include these components and evaluate all inter-related parenting outcomes (parenting self-efficacy, stress, anxiety, depression, social support, and parent-child bonding). Parents could be provided with experiential learning exposure by using computer animations and virtual reality. Future research could be conducted on more fathers and parents from varied geographical regions.

Prevalence of Perinatal Depression and Anxiety in Both Parents: A Systematic Review and Meta-analysis

IMPORTANCE

New and expectant parents experience perinatal mood disorders, with consequences to parenting ability, bonding with the neonate, interpersonal relationships, and health and well-being of parents. Research shows that maternal and paternal perinatal mood disorders are associated, but no recent systematic review has addressed the prevalence of perinatal mood disorders in both mothers and fathers (parental dyad).

OBJECTIVE

To examine the prevalence of perinatal mood disorders in parental dyads and identify factors associated with perinatal mood disorders in parental dyads.

DATA SOURCES

Ovid (MEDLINE, Embase, and PsycINFO) and Web of Science were searched from January 1, 1990, to June 8, 2021, for observational studies reporting on the prevalence of perinatal depression or anxiety in a parental dyad.

STUDY SELECTION

Studies reporting the prevalence of anxiety or depression in both members of a parental dyad were included, with diagnosis according to established criteria (Diagnostic and Statistical Manual of Mental Disorders [Fifth Edition], International Classification of Diseases, 11th Revision) or use of validated screening tools.

DATA EXTRACTION AND SYNTHESIS

Prevalence data were extracted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data were analyzed in subgroups: antenatal depression, early postnatal depression (0-12 weeks), late postnatal depression (3-12 months), and perinatal anxiety. Pooled prevalence was calculated using a random-effects meta-analysis model. Quality assessment was performed using Joanna Briggs Institute Appraisal Checklist for Studies Reporting Prevalence Data. Data were analyzed in June 2021.

MAIN OUTCOMES AND MEASURES

Prevalence of perinatal anxiety and perinatal depression in parental dyads.

RESULTS

Twenty-three studies were included, with data from 29 286 couples. The pooled prevalence of antenatal depression in both parents was 1.72% (95% CI, 0.96%-2.48%; P < .001). The prevalence of early postnatal depression (up to 12 weeks post partum) was 2.37% (95% CI, 1.66%-3.08%; P < .001) and the prevalence of late postnatal depression (3-12 months post partum) was 3.18% (95% CI, 2.3-4.05; P < .001). Only 3 studies reported on perinatal anxiety in both parents, precluding a quantitative analysis.

CONCLUSIONS AND RELEVANCE

In up to 3.18% of couples, both parents may concurrently experience perinatal depression. Perinatal health care must consider the mental health needs of parents, both as individuals and as a parental dyad. Further research is needed to examine outcomes in families where both parents experience perinatal mood disorders.

Physical and mental health changes in the five years before and five years after childbirth: A population-based panel study in first-time mothers and fathers from Germany

BACKGROUND

The transition to parenthood is characterized by far-reaching changes in life. However, little prospective-longitudinal evidence from general population samples exists on changes of general physical and mental health in the years around the birth of a child among mothers and fathers.

METHODS

Using data from the German Socio-Economic Panel Study (SOEP), this study examined continuous and discontinuous short- and long-term changes of general physical and mental health from five years before until five years after the birth of the first child in women (N = 1,912) and men (N = 1,742). Whether a child was born was assessed annually throughout the study. Physical and mental health was assessed biannually from 2002 to 2018 with the SF-12v2.

RESULTS

Multilevel analyses revealed that women experienced a considerable decrease of physical health during pregnancy, which remitted after delivery. On average, women's mental health increased in the last year before and first year after delivery. These mental health improvements were stronger in older vs. younger mothers and remained largely stable in the years after childbirth. In contrast, little evidence for changes of general physical or mental health in (expectant) fathers was found.

LIMITATIONS

Physical and mental health was assessed with a short questionnaire only (SF-12v2).

CONCLUSIONS

On average, women's mental health tends to improve before and after the birth of the first child. Men seem to be much less affected by the birth of a child than many previous studies suggest.

Prevalence of anxiety and post-traumatic stress (PTS) among the parents of babies admitted to neonatal units: A systematic review and meta-analysis

BACKGROUND

Parents of babies admitted to neonatal units (NNU) are exposed to a range of potentially distressing experiences, which can lead to mental health symptoms such as increased anxiety and post-traumatic stress (PTS). This review aimed to describe how anxiety and PTS are defined and assessed, and to estimate anxiety and PTS prevalence among parents of babies admitted to NNU.

METHOD

Medline, Embase, PsychoINFO, Cumulative Index to Nursing and Allied Health literature were searched to identify studies published prior to April 14, 2021. Included studies were assessed using Hoy risk of bias tool. A random-effects model was used to estimate pooled prevalence with 95% CIs. Potential sources of variation were investigated using subgroup analyses and meta-regression. The review is registered with PROSPERO (CRD42020162935).

FINDINGS

Fifty six studies involving 6,036 parents met the review criteria; 21 studies assessed anxiety, 35 assessed PTS, and 8 assessed both. The pooled prevalence of anxiety was 41.9% (95%CI:30.9, 53.0) and the pooled prevalence of PTS was 39.9% (95%CI:30.8, 48.9) among parents up to one month after the birth. Anxiety prevalence decreased to 26.3% (95%CI:10.1, 42.5) and PTS prevalence to 24.5% (95%CI:17.4, 31.6) between one month and one year after birth. More than one year after birth PTS prevalence remained high 27.1% (95%CI:20.7, 33.6). Data on anxiety at this time point were limited. There was high heterogeneity between studies and some evidence from subgroup and meta-regression analyses that study characteristics contributed to the variation in prevalence estimates.

INTERPRETATION

The prevalence of anxiety and PTS was high among parents of babies admitted to NNU. The rates declined over time, although they remained higher than population prevalence estimates for women in the perinatal period. Implementing routine screening would enable early diagnosis and effective intervention.
