Effect of mindfulness-based interventions on mental health of perinatal women with or without current mental health issues: A systematic review and meta-analysis of randomized controlled trials

Effects of non-pharmacological interventions on depressive and anxiety symptoms in pregnant women: a systematic review and network meta-analysis

Background

Given the distinctive physiological characteristics of pregnant women, non-pharmacological therapies are increasingly being used to improve depressive and anxiety symptoms. Our objective was to explore and compare the impact of various non-pharmacological interventions in improving depressive and anxiety symptoms, and to identify the most effective strategies for pregnant women with depressive and/or anxiety symptoms.

Methods

We conducted a systematic search of PubMed, Embase, the Cochrane Library, and Web of Science for randomized controlled trials (RCTs) that compared non-pharmacological interventions to usual care, from the inception of each database up to October 5, 2024. We included pregnant women with singleton pregnancies who, at baseline, exhibited early signs of depressive and/or anxiety symptoms but did not meet clinical diagnostic criteria or exceed the threshold for clinically significant symptoms. We excluded pregnant women diagnosed with schizophrenia, bipolar disorder, or severe acute psychiatric conditions, those with a history of substance abuse, and those undergoing in vitro fertilisation. We performed both pairwise meta-analyses and random-effects network meta-analyses (NMAs), calculating standardised mean differences (SMDs) with 95% credible intervals (CrI). We used the surface under the cumulative ranking probability curve (SUCRA) to estimate treatment ranking probabilities. The outcomes were assessed in two groups of participants: a high-risk pregnancy group, including pregnant women with depressive and/or anxiety symptoms and high-risk pregnancies (defined as having a history of miscarriage, pregnancy complications such as gestational hypertension, gestational diabetes mellitus, or preeclampsia, and advanced maternal age (i.e., over 35 years old); and a healthy group, including participants who exhibited depressive and/or anxiety symptoms only during pregnancy and did not have other high-risk pregnancy conditions or underlying health issues. This study is registered with PROSPERO, CRD42024523053.

Findings

We included 101 studies (92 RCTs and 9 quasi-RCTs) involving a total of 15,330 participants across 11 interventions (mindfulness, education, counseling, cognitive behavioral therapy, muscle acupoint therapy, relaxation, mind-body exercise, psychotherapy, foetal movement counting, physical exercise, and music). Among the studies included in this analysis, 73 studies exhibited a low risk of bias, 9 studies had an unclear risk of bias, and 19 studies demonstrated a high risk of bias. The results indicate that, for both high-risk pregnancy population and healthy populations, mindfulness therapy was found to be an effective non-pharmacological treatment for significantly improving depressive and anxiety symptoms in pregnant women compared with control groups. For pregnant women with depressive symptoms, mindfulness therapy (SUCRA = 80%; SMD = -0.86, 95% CrI = -1.2, -0.52; Nn = 598), cognitive behavioral therapy (CBT) (SUCRA = 65%; SMD = -0.69, 95% CrI = -1.0, -0.39; Nn = 712), and education therapy (SUCRA = 48%; SMD = -0.54, 95% CrI = -0.86, -0.23; Nn = 2285) all significantly improve depressive symptoms. In the subgroup analysis of healthy populations, muscle acupoint therapy (SUCRA = 77.17%; SMD = -0.89, 95% CrI = -1.55, -0.23; N = 99) and mind-body exercise (SUCRA = 47.54%; SMD = -0.53, 95% CrI = -0.88, -0.19; N = 352) also significantly reduce depressive symptoms. Subgroup analysis shows that, in addition to mindfulness therapy, mind-body exercises (SUCRA = 67.43%; SMD = -0.97, 95% CrI = -1.61, -0.33; N = 382) and cognitive-behavioral therapy (SUCRA = 52.60%; SMD = -0.74, 95% CrI = -1.38, -0.09; N = 480) may also be effective in alleviating anxiety symptoms among healthy pregnant women.

Interpretation

Our findings indicate that mindfulness therapy significantly reduces the risk of depressive and anxiety symptoms in both high-risk pregnancy population and healthy populations. Therefore, when selecting non-pharmacologic therapies for managing depressive and anxiety symptoms during pregnancy, it is recommended that this therapy be considered. We cannot overlook the limitations of this study. For example, some interventions, such as muscle acupoint therapy for depressive symptoms and relaxation therapy for anxiety symptoms, have limited literature support. Additionally, the diversity of conditions within the high-risk pregnancy population and the high heterogeneity observed in certain interventions are also issues that require attention. These factors may affect the accuracy of the data results. Although we have employed reliable methods to address these issues, the findings of this study should still be interpreted with caution.

The effect of mindfulness-based interventions on mental health outcomes and wellbeing of informal caregivers of people with mental illness: A systematic review and meta-analysis

The increasing prevalence of mental illness has resulted in a growing burden on informal caregivers. Mindfulness-based interventions, as a form of psychotherapy, have shown efficacy in alleviating psychological stress and enhancing emotional and physical well-being. However, the utilisation of mindfulness-based interventions for informal caregivers of individuals with mental illness remains limited. The aim of the meta-analysis is to evaluate the impact of mindfulness-based interventions on the mental health and well-being among informal caregivers of people with mental illness. A comprehensive literature search was conducted across seven electronic databases (PubMed, Scopus, Web of Science, Cochrane Library, Embase, APA PsycINFO and CINAHL Ultimate) from the inception of these databases until 20 July 2023. Two authors independently screened the studies and extracted the relevant data. The meta-analysis was performed by using Stata 12.0 software, and the effect sizes were calculated utilising standardised mean difference (SMD) along with their corresponding 95% confidence intervals (CI). The meta-analysis included 13 studies with 1007 participants, and the results demonstrated that mindfulness-based interventions were efficacious in reducing stress (SMD = -0.80, 95% CI [-1.33, -0.28], p = 0.003), depression (SMD = -0.43, 95% CI [-0.62, -0.24], p < 0.001) and caregiver burden (SMD = -0.21, 95% CI [-0.40, -0.01], p = 0.038), and enhancing the mindfulness level (SMD = 0.37, 95% CI [0.09, 0.65], P = 0.010) and quality of life (SMD = 0.22, 95% CI [0.04, 0.39], p = 0.015) among informal caregivers of people with mental illness, but not on anxiety reduction (SMD = -0.19, 95% CI [-0.49, 0.10], p = 0.198). Furthermore, future research should aim to employ more rigorous methodologies to confirm the effectiveness.

Effects of mindfulness-based interventions (MBIs) on depression in pregnant women: A systematic review and meta-analysis

OBJECTIVE

We synthesized the effects of mindfulness-based interventions (MBIs) on depression in pregnant women.

METHOD

Ten electronic databases were searched from inception to September 2022. We reviewed studies on outcomes for pregnant women with depression receiving mindfulness-based interventions. We only reviewed studies written in English. A random-effects model was used to compute the effect size. Funnel plot, Q statistics, and I2 were used to test the heterogeneity across studies. We examined moderators to explore sources of heterogeneity.

RESULTS

Across 19 included studies (N = 1480), 717 pregnant women participated in mindfulness interventions; 763 served as controls. Mean age ranged from 25.3 to 33.6 years. Overall, mindfulness-based interventions showed reduced depression compared to control groups (g = 0.457, 95%CI 0.254, 0.659, I2 = 68 %). With subgroup analysis, mindfulness-based cognitive therapy had a greater effect on reducing depressive symptoms (g = 1.13) than mindfulness-based stress reduction (g = 0.64) and adapted mindfulness-based interventions (g = 0.31). No quality indicators moderated the ES of mindfulness-based interventions on depression.

CONCLUSION

Mindfulness-based interventions significantly improved depression among pregnant women, especially mindfulness-based cognitive therapy (MBCT). Clinicians and health providers should consider using MBIs as alternative complementary treatment for improving and preventing depression in pregnant women.

Efficacy of contextual therapies in perinatal depression and anxiety: A systematic review and meta-analysis

BACKGROUND

There are previous meta-analyses on the efficacy of cognitive behavioral therapy or mindfulness-based therapies in the perinatal period, but no previous review has focused on contextual therapies as a whole. The aim of this study was to carry out a systematic review and meta-analysis of the efficacy of contextual therapies on depressive and anxious symptoms in women in the perinatal period.

METHODS

A systematic search for randomized clinical trials has been carried out in the PUBMED, CINAHL, Psyc-INFO and Cochrane Library search engines. For the quantitative synthesis, the Morris effect size measure has been used.

RESULTS

A total of 34 RCTs have been found, of which 30 have been used for meta-analysis. The mean effect size of the studies on depression scores was dppc2 = -0.81 (95% CI = -1.12 to -0.50), while it was dppc2 = -1.04 (95% CI = -1.54 to -0.53) in the case of studies on anxiety scores. These effect sizes decreased to medium effect sizes when corrected for publication bias.

LIMITATIONS

The main limitations are the quality of the included studies, publication bias, and the limited number of studies on contextual therapies other than mindfulness-based therapies.

CONCLUSIONS

In conclusion, this systematic review found a large number of efficacy studies on mindfulness-based therapies and a small number of studies on the other contextual therapies. The effect sizes found are consistent with previous meta-analyses in the perinatal period.

Effectiveness of the third wave cognitive behavior therapy for peripartum depression treatment-A systematic review

INTRODUCTION

To investigate the effectiveness of third-wave cognitive behavior therapies in the treatment of peripartum depression.

METHOD

A systematic review of the effectiveness of psychological interventions in treating peripartum depression focus on the Third Wave has been conducted. The electronic databases MEDLINE, PsycINFO, Web of Science and Clinical Trials were searched, using a combination of different search terms. Data were independently extracted by two authors and a synthesis of the results was offered. Methodological quality was assessed by three authors, using ROBE-2 and MINORS. Search date was conducted in February 2022 and the search was re-run in November 2022 for new entries.

FINDINGS

Six papers were included and reported, focused on, the effectiveness of Third Wave approach interventions in reducing depressive symptoms. Papers included the following intervention approaches: Behavioral intervention (n = 2), Mindfulness (n = 2), Dialectical Behavior Therapy (n = 1) and Acceptance and Commitment Therapy (n = 1). All six papers were consistent in that interventions lead to a decrease in depression symptoms. However, risk of bias evaluation showed that all were critical low, but one paper was high quality.

CONCLUSION AND IMPLICATIONS FOR PRACTICE AND RESEARCH

Systematic review showed that third-wave approaches are promising in effectiveness to reduce depression symptoms in peripartum women. However, more high-quality studies with follow-up are needed.

Effectiveness and cost-effectiveness of an electronic mindfulness-based intervention to improve maternal mental health in the peripartum: study protocol for a randomised controlled trial

BACKGROUND

Perinatal women are highly vulnerable to developing mental health issues and particularly susceptible to a recurrence of psychiatric illness. Poor mental health during the perinatal period can have long-term impacts on the physical and psychiatric health of both mother and child. A potentially useful strategy to improve women's mental health is through a mobile application teaching mindfulness, an evidence-based technique helping individuals focus on the present moment.

METHODS

A mixed method, prospective randomised controlled trial. The study group comprise women aged 18 years and over, who are attending the public and private maternity clinics at Mater Mothers' Hospital. A sample of 360 prenatal women will be randomised into the intervention group (with the use of the mindfulness app) or usual care. Participants will remain in the study for 11 months and will be assessed at four timepoints for changes in postnatal depression, mother-infant bonding, and quality of life. A cost-effectiveness evaluation will also be conducted using quality-adjusted life year (QALY) calculations. A random selection of intervention participants will be invited to attend focus groups to give feedback on the mindfulness app.

DISCUSSION

Previous studies have found mindfulness interventions can reduce stress, anxiety, depression, and sleep disturbances in a prenatal population. The risks of the intervention are low, but could be of significant benefit for women who are unable to attend face-to-face appointments due to geographical, financial, or time barriers; during endemic or pandemic scenarios; or due to health or mobility issues.

The effect of an adapted Mindfulness-Based Stress Reduction program on mental health, maternal bonding and birth outcomes in psychosocially vulnerable pregnant women: a study protocol for a randomized controlled trial in a Danish hospital-based outpatient setting

BACKGROUND

Stress and mental disorders in pregnancy can adversely affect the developing fetus. Women with a preconception history of mental disorders or of psychosocial vulnerabilities are at increased risk of experiencing perinatal stress or mental health problems. Mindfulness-Based-Stress-Reduction (MBSR) is an acceptable intervention for pregnant women and has a growing evidence-base with meta-analyses consistently pointing to reductions in symptoms of stress, anxiety and depression. This study protocol aim to address the need for a wider array of evidence-based and non-pharmacological options during pregnancy to reduce stress and improve mental health in a psychosocially highly vulnerable group of women.

METHODS

Pregnant women with a preconception history of mental disorders or psychosocial vulnerabilities (n = 240) will be recruited from an obstetric ambulatory clinic at Copenhagen University Hospital, Hvidovre, Denmark. Recruitment for the study began in March 2022 and will continue until the desired number of participants is reached. Consenting pregnant women will be randomized to one of two study arms, an adapted MBSR program as add on to usual care or usual care alone. The primary outcome is mental wellbeing at nine months post-randomization. Secondary and exploratory outcomes include stress, anxiety, depression, and maternal antenatal attachment, experience of childbirth, delivery and mode of delivery. Mindfulness and self-compassion are examined as possible mediators of the effect on outcomes.

DISCUSSION

Teaching the skills of mindfulness meditation to a psychosocially vulnerable group of pregnant women could prove a viable and non-pharmacological approach to improve mental health and wellbeing during pregnancy, reduce stress and support the transition to parenthood. Mindfulness-Based Stress Reduction does not target a particular group, and results from the study is thus of potential relevance for pregnant women in general as a means of reducing stress and improving perinatal mental health and wellbeing.

Non-pharmacological interventions for the management of perinatal anxiety in primary care: a meta-review of systematic reviews

BACKGROUND

Perinatal anxiety (PNA), anxiety that occurs during pregnancy and/or up to 12 months postpartum, is estimated to affect up to 21% of women, and may impact negatively on mothers, children, and their families. The National Institute for Health and Care Excellence (NICE) has called for further research around non-pharmacological interventions in primary care for PNA.

AIM

To summarise the available international evidence on non-pharmacological interventions for women with PNA in a primary care population.

DESIGN & SETTING

A meta-review of systematic reviews (SRs) with narrative synthesis was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidance.

METHOD

Systematic literature searches were conducted in 11 health-related databases up to June 2022. Titles, abstracts, and full-text articles were dual-screened against pre-defined eligibility criteria. A variety of study designs were included. Data were extracted about study participants, intervention design, and context. Quality appraisal was performed using the AMSTAR 2 tool (A MeaSurement Tool to Assess systematic Reviews). A patient and public involvement group informed and contributed towards this meta-review.

RESULTS

Twenty-four SRs were included in the meta-review. Interventions were grouped into the following six categories for analysis purposes: psychological therapies; mind-body activities; emotional support from healthcare professionals (HCPs); peer support; educational activities; and alternative or complementary therapies.

CONCLUSION

In addition to pharmacological and psychological therapies, this meta-review has demonstrated that there are many more options available for women to choose from that might be effective to manage their PNA. Evidence gaps are present in several intervention categories. Primary care clinicians and commissioners should endeavour to provide patients with a choice of these management options, promoting individual choice and patient-centred care.

The Effect of Digital Mindfulness Interventions on Depressive, Anxiety, and Stress Symptoms in Pregnant Women: A Systematic Review and Meta-Analysis

Introduction. Pregnancy is a unique time in a woman's life that can be both exciting and challenging. It is also a period that can be associated with significant stress, anxiety, and depression, which can have negative consequences for both the mother and the baby. Mindfulness interventions are known to be a well-suited treatment and prevention method for psychiatric symptoms in pregnancy, and web-based applications have been explored. We here present an up-to-date systematic review and meta-analysis of randomized-controlled trials to investigate the effect of digital-based mindfulness interventions on depressive, anxiety, and stress symptoms during pregnancy. Methods. The systematic literature search and data extraction was performed by two independent raters. It resulted in 13 eligible studies overall comprising 1373 participants. We conducted random-effects meta-analyses for depressive, anxiety, and stress symptoms after completion of a digital mindfulness intervention (compared to a control group). Results. Digital mindfulness intervention methods were significantly able to reduce depression (g = -0.47, 95% CI [-0.9; -0.09]) and anxiety symptoms (g = -0.41, 95% CI [-0.77; -0.05]), but not stress symptoms. These effects were moderated by the attrition rate (βDepression = 0.025, pDepression < 0.01; βAnxiety = 0.022, pAnxiety < 0.01; βStress = 0.022, pStress < 0.01). Primiparity also had a significant influence on the intervention effect regarding depression symptoms (β = 0.033, p = 0.024). Conclusions. Digital mindfulness interventions are a promising method to reduce mental health symptoms in pregnant women. We identified certain parameters moderating this effect, for example, primiparity and the attrition rate.

Resident Physician Perspectives on Mindfulness Education in Residency: A Multispecialty Qualitative Assessment of Clinical Care Impact

Background

Mindfulness training positively influences residents personally and professionally. Routine integration into residency may be impacted by limited understanding of the ways in which mindfulness training enhances clinical care.

Objective

We explored residents' direct experience and personal application of mindfulness in their clinical work following 10 hours of mindfulness training.

Methods

Mindfulness training sessions were facilitated between 2017 and 2019 for 5 groups of residents: pediatrics, ophthalmology, postgraduate year (PGY)-1 anesthesiology, and 2 different years of PGY-1 family medicine residents. Training was integrated into resident protected didactic time and attendance was expected, although not mandated, with the exception of pediatrics, in which the department mandated the training. Qualitative evaluation was conducted using a voluntary, semi-structured, de-identified phone interview within 2 months post-training. Reviewers independently coded the transcripts and then dialogued to reach consensus around emergent themes.

Results

Thirty-six of 72 residents (50%) who participated in the training completed interviews. Themes were similar across specialties. All residents acknowledged the potential usefulness of mindfulness training during residency. Six residents (17%) reported they had not applied the mindfulness training to their daily work by the end of the course. There were 4 emergent themes related to clinical application of mindfulness training: integrating brief moments of mindfulness practice, self-awareness, relational presence with patients, and maintaining perspective during clinical encounters and residency training as a whole.

Conclusions

After completing a 10-hour mindfulness training program, residents reported enhanced perspective-taking and relationship-building with themselves and their patients in clinical settings across medical and procedural specialties.

Effects of a maternal mindfulness intervention targeting prenatal psychological distress on infants' meconium microbiota: A randomized controlled trial

BACKGROUND

Maternal psychological distress could affect gut microbiota of the infant; however, previous studies to date have been observational.

OBJECTIVE

To investigate the effects of mindfulness-based intervention (MBI) during pregnancy on the meconium microbiota of infants by alleviating maternal psychological distress.

DESIGN

Randomized controlled trial.

METHOD

Pregnant women with symptoms of depression or anxiety were randomized to either the intervention group (n = 80), comprising usual perinatal care and six digitally guided self-help MBI sessions, or the control group (n = 80) who underwent usual perinatal care. Meconium was collected within 48 h of birth to evaluate the infant's gut microbiota. The Kruskal-Wallis rank sum test, analysis of similarities, and DESeq2 were performed to explore the effects of the MBI on alpha and beta diversity indices and specific genera.

RESULTS

There were no significant differences between groups regarding the alpha diversity indices, including Chao1 and Simpson (p = 0.83 and p = 0.58). However, there was a significant between-group difference in the beta diversity index (R=0.02, p = 0.03). Bifidobacterium (log² fold change=-1.90, FDR=0.002) and Blautia (log² fold change=-1.45, FDR=0.01) were abundant in the intervention group, whereas Staphylococcus (log² fold change=1.44, FDR=0.01) was abundant in the control group.

CONCLUSIONS

MBI aimed at alleviating maternal psychological distress can positively alter the meconium microbiota of infants. However, the mechanisms underlying the effects of maternal mindfulness during pregnancy on infant meconium microbiota require further exploration.

The Efficacy of Digital Cognitive–Behavioral Interventions in Supporting the Psychological Adjustment and Sleep Quality of Pregnant Women with Sub-Clinical Symptoms: A Systematic Review and Meta-Analysis

The present meta-analysis investigated the overall and differential efficacy of digital cognitive–behavioral therapies (CBTs) vs. third-generation CBTs deployed to pregnant women in reducing sub-clinical depression, anxiety, and stress symptoms while fostering sleep quality and quality of life. A PRISMA-guided systematic search was used, including randomized controlled trials (RCTs) evaluating the above-mentioned interventions. Data were pooled using either the mean difference (MD) or standardized MD (SMD). Sub-group analyses were carried out when appropriate. The primary outcomes were depression, anxiety, and stress symptoms, as well as sleep quality and quality of life. The interventions’ acceptability was evaluated through the odds ratio (OR) of drop-out rates. Seven RCTs were included, comprising 1873 pregnant women. The results showed the interventions’ efficacy in terms of reducing depression symptoms (SMD = −0.36, CI = 0.61, −0.11, k = 9) at the endpoint, although it was not maintained at follow-up during the postpartum period. The interventions’ efficacy in terms of reducing anxiety symptoms (SMD = 1.96, CI = −2.72, −1.21, k = 3) at the endpoint was also significant, while having no effect on sleep quality. The interventions were well accepted (OR = 1.68; 95% CI = 0.84, 3.35; k = 7). Although no sound conclusions can be drawn concerning the joint or differential efficacy of the considered interventions, this study was useful in highlighting the need to develop evidence-based digital prevention programs for pregnant women with sub-clinical symptoms.
