Maternal anxiety negatively influences child outcomes. Reliable estimates have not been established because of varying published prevalence rates. To establish summary estimates for the prevalence of maternal anxiety in the antenatal and postnatal periods. We searched multiple databases including MEDLINE, Embase, and PsycINFO to identify studies published up to January 2016 with data on the prevalence of antenatal or postnatal anxiety. Data were extracted from published reports and any missing information was requested from investigators. Estimates were pooled using random-effects meta-analyses. We reviewed 23 468 abstracts, retrieved 783 articles and included 102 studies incorporating 221 974 women from 34 countries. The prevalence for self-reported anxiety symptoms was 18.2% (95% CI 13.6-22.8) in the first trimester, 19.1% (95% CI 15.9-22.4) in the second trimester and 24.6% (95% CI 21.2-28.0) in the third trimester. The overall prevalence for a clinical diagnosis of any anxiety disorder was 15.2% (95% CI 9.0-21.4) and 4.1% (95% CI 1.9-6.2) for a generalised anxiety disorder. Postnatally, the prevalence for anxiety symptoms overall at 1-24 weeks was 15.0% (95% CI 13.7-16.4). The prevalence for any anxiety disorder over the same period was 9.9% (95% CI 6.1-13.8), and 5.7% (95% CI 2.3-9.2) for a generalised anxiety disorder. Rates were higher in low- to middle-income countries. Results suggest perinatal anxiety is highly prevalent and merits clinical attention. Research is warranted to develop evidence-based interventions.

Antenatal and postpartum depression are very common and have significant consequences for mothers and their children. This review examines which antenatal depression (AD) and postpartum depression (PPD) treatment interventions are most efficacious in improving parenting and/or child development. CINAHL, Scopus, Cochrane Systematic Reviews, Cochrane Controlled Trials, Medline (OVID), Embase (OVID), PsychINFO, PsycARTICLES, AMED, and reference lists were searched. Randomized controlled trials (RCTs) and quasi‐experimental studies assessing the effect of AD, PPD, or both treatment interventions on parenting and/or child development were included. Meta‐analysis was conducted using random effects when possible. Thirty‐six trials (within 40 articles) met criteria for review. Interventions include interpersonal psychotherapy (IPT), cognitive behavioural therapy (CBT), peer support, maternal‐child interaction guidance, and other interventions, such as massage. For AD, IPT, CBT, and massage produced large effects on parenting (e.g. adjustment and attention toward infant) and child development (e.g. behaviour). For PPD, maternal‐child interaction guidance and psychotherapeutic group support produced large effects on parenting (e.g. sense of competence) and child development (e.g. cortisol). However, meta‐analysis revealed nonsignificant effects of IPT on maternal‐child attachment and CBT on parenting stress. Promising findings exist for IPT, CBT, maternal‐child interaction guidance, massage, and psychotherapeutic group support for specific parenting and/or child development outcomes. Additional RCTs using measures already employed in the literature are required to conduct necessary meta‐analysis and fully elucidate treatment effects.

Mental disorders are among the most common morbidities of pregnancy and the postnatal period, and can have adverse effects on the mother, her child, and family. This Series paper summarises the evidence about epidemiology, risk factors, identification, and interventions for non-psychotic mental disorders. Although the phenomenology and risk factors for perinatal mental disorders are largely similar to those for the disorders at other times, treatment considerations differ during pregnancy and breastfeeding. Most randomised controlled trials have examined psychosocial and psychological interventions for postnatal depression, with evidence for effectiveness in treating and preventing the disorder. Few high-quality studies exist on the effectiveness or safety of pharmacological treatments in the perinatal period, despite quite high prescription rates. General principles of prescribing of drugs in the perinatal period are provided, but individual risk–benefit analyses are needed for decisions about treatment.

Postpartum depression and anxiety are under-addressed public health problems with numerous treatment access barriers, including insufficiently available mental health specialist providers. To examine the effectiveness of nurse-delivered telephone interpersonal psychotherapy (IPT) for postpartum depression. Trial registration ISRCTN88987377. Postpartum women (n = 241) with major depression (on the Structured Clinical Interview for DSM-IV (SCID-I)) from 36 Canadian public health regions in rural and urban settings were randomly assigned to 12 weekly 60 min nurse-delivered telephone-IPT sessions or standard locally available care. The primary outcome was the proportion of women clinically depressed at 12 weeks post-randomisation, with masked intention-to-treat analysis. Secondary outcomes examined included comorbid anxiety, self-reported attachment and partner relationship quality. At 12 weeks, 10.6% of women in the IPT group (11/104) and 35% in the control group (35/100) remained depressed (OR = 0.22, 95% CI 0.10-0.46), with the IPT group 4.5 times less likely to be clinically depressed (SCID); 21.2% in the IPT group and 51% in the control group had an Edinburgh Postnatal Depression Scale (EPDS) score >12 (OR = 0.26, 95% CI 0.14-0.48), and attachment avoidance decreased more in the IPT group than in the control group (P = 0.02). Significant differences favoured the IPT group for comorbid anxiety and partner relationship quality at all time points, with no differences in health service or antidepressant use. None of the IPT responders relapsed by 36 weeks. Between-group SCID differences were sustained at 24 weeks, but not at 36 weeks. Nurse-delivered telephone IPT is an effective treatment for diverse urban and rural women with postpartum depression and anxiety that can improve treatment access disparities.

Background The Breastfeeding Self-Efficacy Scale and its short-form were developed in Canada and have been used internationally among numerous maternal populations. However, the psychometric properties of the scales have not been reviewed to confirm their appropriateness in measuring breastfeeding self-efficacy in culturally diverse populations. The purpose of this research was to critically appraise and synthesize the psychometric properties of the scales via systematic review. Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Three databases (EMBASE, MEDLINE, and PsycINFO) were searched from 1999 (original publication of the Scale) until April 27, 2022. The search was updated on April 1, 2023. Studies that assessed the psychometric properties of the BSES or BSES-SF were included. Two researchers independently extracted data and completed the quality appraisals. Results Forty-one studies evaluated the psychometrics of the BSES ( n  = 5 studies) or BSES-SF ( n  = 36 studies) among demographically or culturally diverse populations. All versions of the instrument demonstrated good reliability, with Cronbach's alphas ranging from .72 to .97. Construct validity was supported by statistically significant differences in mean scores among women with and without previous breastfeeding experience and by correlations between the scales and theoretically related constructs. Predictive validity was demonstrated by statistically significant lower scores among women who ultimately discontinued breastfeeding compared to those who did not. Conclusion The BSES and BSES-SF appear to be valid and reliable measures of breastfeeding self-efficacy that may be used globally to (1) assess women who may be at risk of negative breastfeeding outcomes (e.g., initiation, duration and exclusivity), (2) individualize breastfeeding support, and (3) evaluate the effectiveness of breastfeeding interventions.

To systematically review and meta-analyze research investigating the association between maternal anxiety during pregnancy and outcomes for mother and baby following the immediate delivery period. MEDLINE, Medline In-Process & Other Non-Indexed Citations, PsycINFO, Embase, CINAHL, and the Cochrane library were searched. English-language, prospective studies providing data on outcomes following delivery in women with and without antenatal anxiety (defined by clinical diagnosis or score on validated scale) were included. Three-hundred-fifty-eight articles were retrieved and 13 were included. Titles and abstracts were screened; two reviewers independently reviewed full text articles, conducted quality assessments, extracted, and checked the data. Where available for > 2 studies, random effect meta-analysis was conducted and heterogeneity was quantified. Subanalyses explored moderators, regardless of heterogeneity, including type of anxiety assessment and timing, among others. There were two outcomes that were amenable to meta-analysis. Antenatal anxiety was significantly associated with postpartum depression (PPD) measured within 6 months postpartum (pooled odds ratio [OR] = 2.64, 95% CI 2.02–3.46; 8 studies), regardless of restricting analyses to those studies controlling for prenatal depression (2.45, 1.77–3.39; 6 studies). Associations were also significant when PPD was measured at 1–3 months (2.57, 1.94–3.40; 7 studies) and 6–10 months (4.42, 1.45–13.49; 3 studies). Maternal anxiety was also associated with reduced odds of breastfeeding (0.63, 0.53–0.74; 5 studies). Antenatal anxiety is associated with PPD up to the first 10 months, independent of prenatal depression, and with lower odds of breastfeeding.

Birth weight is an important determinant of infant growth and development associated with neonatal morbidity (e.g., respiratory distress, hypoglycemia) and mortality, as well as long-term health risks such as developmental delays and chronic conditions (e.g., asthma, type 2 diabetes) in later life. These adverse health outcomes are particularly concerning when infants are born small or large for their gestational age. A potential strategy to improve optimal birth weight is preconception care, with consistent evidence demonstrating a relationship between maternal preconception health and infant birth weight. However, little attention has been given to the influence of paternal preconception health on pregnancy outcomes. This scoping review aimed to capture the existing literature and highlight evidence gaps regarding associations between paternal preconception health and infant birth weight. We followed the Joanna Briggs Institute methodology and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. The review considered studies that included men in the preconception period who identified as the parent of a child for whom infant birth weight outcomes were reported. Medline, PsycINFO, Embase, Scopus and CINAHL databases were searched to June 30, 2024. Two independent reviewers screened the titles/abstracts and full-text articles. Data extraction was performed independently by two researchers using a standardized form in Covidence. The data were synthesized narratively according to the paternal preconception health factors identified within the included studies (e.g., physical well-being, health behaviors, substance use, environmental exposures, mental health, and treatment effects). From 7,690 citations, 57 published studies were included in the review. Most studies were conducted in China (n = 18, 31.6%) or the United States (US) (n = 17, 29.8%) and used a cohort design (n = 54, 94.7%). Our review identified growing evidence that specific paternal preconception factors, such as physical well-being (e.g., BMI, physical health), certain medications (e.g., recreational drugs, sulfonylureas, diazepam), and environmental chemical exposure, may adversely influence infant birth weight. There are mixed findings related to other paternal health factors, including some health behaviors (e.g., nutrition, sleep, physical activity), substance use, and mental health. Consideration should be given to expanding preconception counseling and public health initiatives to include fathers, to improve paternal health and potentially reduce risks to offspring (e.g., birth weight). We also identified key areas where further research is required to advance knowledge in this field.

Up to 13% of psychiatric patients are readmitted shortly after discharge. Interventions that ensure successful transitions to community care may play a key role in preventing early readmission. To describe and evaluate interventions applied during the transition from in-patient to out-patient care in preventing early psychiatric readmission. Systematic review of transitional interventions among adults admitted to hospital with mental illness where the study outcome was psychiatric readmission. The review included 15 studies with 15 non-overlapping intervention components. Absolute risk reductions of 13.6 to 37.0% were observed in statistically significant studies. Effective intervention components were: pre- and post-discharge patient psychoeducation, structured needs assessments, medication reconciliation/education, transition managers and in-patient/out-patient provider communication. Key limitations were small sample size and risk of bias. Many effective transitional intervention components are feasible and likely to be cost-effective. Future research can provide direction about the specific components necessary and/or sufficient for preventing early psychiatric readmission.

One in 5 women experience mental illness in pregnancy or post partum. Universal preventive interventions have not lowered the incidence of perinatal mental illness, perhaps because those at highest risk were not targeted. Outside of pregnancy, chronic physical conditions are known to confer increased risk for mental illness. Our objective was to examine the association between chronic physical conditions and risk of perinatal mental illness. We conducted a population-based retrospective cohort study using linked health administrative data sets in Ontario, Canada, in 2005 to 2015. We compared 77,385 women with chronic physical conditions to 780,619 women without such conditions, all of whom had a singleton live birth. Excluded were women with a mental illness diagnosis within 2 years before pregnancy. Chronic physical conditions were captured using the Agency for Healthcare Research and Quality Chronic Condition Indicator, applied to acute healthcare encounters in the 2 years before pregnancy. The outcome was perinatal mental illness, defined by a mental illness or addiction diagnosis arising between conception and 365 days post partum. The outcome was further defined by timing (prenatal or post partum) and specific diagnosis (psychotic disorder, mood or anxiety disorder, substance use disorder, self-harm, or other). Modified Poisson regression generated relative risks and 95% confidence intervals (CIs), adjusted for age, parity, rural residence, income quintile, and remote history of mental health care. Women in the cohort had an average age of 29.6 years (standard deviation 5.4), 44.2% were primiparous, 11.0% lived in a rural area, 40.1% were in the lowest 2 income quintiles, and 47.9% had a remote history of mental health care. More women with (20.4%) than without (15.6%) a chronic physical condition experienced perinatal mental illness-an adjusted relative risk (aRR) of 1.20 (95% CI 1.18-1.22, p < 0.0001). The aRRs were statistically significant for mental illness in pregnancy (1.12, 95% CI 1.10-1.15, p < 0.0001) and post partum (1.25, 95% CI 1.23-1.28, p < 0.0001). Psychotic disorders (aRR 1.50, 95% CI 1.36-1.65, p < 0.0001), mood or anxiety disorders (aRR 1.19, 95% CI 1.17-1.21, p < 0.0001), substance use disorders (aRR 1.47, 95% CI 1.34-1.62, p < 0.0001), and other mental illness (aRR 1.68, 95% CI 1.50-1.87, p < 0.0001) were more likely in women with than without chronic physical conditions, but not self-harm (aRR 1.14, 95% CI 0.87-1.48, p = 0.34). The study was limited by reliance on acute health care encounters to measure chronic physical conditions and the inability to capture undiagnosed mental health problems. Findings from this study suggest that women with a chronic physical condition predating pregnancy may be at heightened risk of developing mental illness in the perinatal period. These women may require targeted efforts to lower the severity of their condition and improve their coping strategies and supports in pregnancy and thereafter.

Background Stress and anxiety are common in pregnancy and shown to have adverse effects on maternal and infant health outcomes. The aim of this review and meta-analysis was to assess the effectiveness of music-based interventions in reducing levels of stress or anxiety among pregnant women. Methods Six databases were searched using key terms relating to pregnancy, psychological stress, anxiety and music. Inclusion criteria were randomised controlled or quasi-experimental trials that assessed the effect of music during pregnancy and measured levels of psychological stress or anxiety as a primary or secondary outcome. Two authors independently assessed and extracted data. Quality assessment was performed using The Cochrane Collaboration risk of bias criteria. Meta-analyses were conducted to assess stress and anxiety reduction following a music-based intervention compared to a control group that received routine antenatal care. Results Five studies with 1261 women were included. Music interventions significantly reduced levels of maternal anxiety (Standardised Mean Difference (SMD): -0.21; 95% Confidence Interval (CI) -0.39, −0.03; p  = 0.02). There was no significant effect on general stress (SMD: -0.08; 95% CI -0.25, 0.09; p  = 0.35) or pregnancy-specific stress (SMD: -0.02; 95% CI -0.19, 0.15; p  = 0.80). The methodological quality of included studies was moderate to weak, all studies having a high or unclear risk of bias in allocation concealment, blinding and selective outcome reporting. Conclusions There is evidence that music-based interventions may reduce anxiety in pregnancy; however, the methodological quality of the studies was moderate to weak. Additional research is warranted focusing on rigour of assessment, intensity of interventions delivered and methodological limitations.
