Relaxation during pregnancy: what are the benefits for mother, fetus, and the newborn? A systematic review of the literature

Effects of maternal posture and cognitive-behavioral interventions on labor outcomes in primigravidas with abnormal fetal head position: a randomized controlled clinical trial

OBJECTIVE

Fetal head malposition can result in neonatal and maternal complications. Fetal head malposition occurs frequently in labor. Appropriate and timely managements are required. Maternal posture and cognitive-behavioral interventions could improve labor outcomes in primigravidas with fetal head malposition.

METHODS

A randomized controlled clinical trial was performed between January and December 2022 (Chinese Clinical Trial Registry, ChiCTR2100049359). Eligible primigravidas were randomly assigned into four groups. Group A received traditional perinatal care. Group B, C, and D received posture management, posture management with music therapy, and posture management with video education, respectively, in addition to traditional perinatal care. The maternal postures referred to place pregnant women in certain positions (lateral, lateral-prone, hands and knees, open knee-chest) to change the anatomical structure of pelvis, thus, to facilitate the fetal downward movement and birth. Maternal and neonatal outcomes were recorded and compared.

RESULTS

A total of 136 primigravidas were included, with 34, 35, 34, and 33 women in group A, B, C, and D, respectively. The incidences of cesarean section were lower in groups B, C, and D than that in group A (5.7%, 2.9%, and 3.0% versus 20.6%, p < 0.05). The fetal position correction rates at the time of full dilation of cervix were higher in groups B, C, and D than that in group A (66.7%, 63.6%, 68.8% versus 27.6%, p < 0.05). Primigravidas in groups B, C, and D had better experiences and a lower anxiety level than those in group A (p < 0.001). The four groups had no statistically significant differences in the total labor duration, operative vaginal delivery, umbilical artery blood pH, and neonatal Apgar scores.

CONCLUSION

Fetal head malposition could happen in primigravidas. Maternal posture management and cognitive-behavioral interventions during labor could improve labor outcomes in primigravidas with fetal head malposition.

Perinatal meaning-making and meaning-focused coping in the COVID-19 pandemic

INTRODUCTION

The COVID-19 pandemic caused unprecedented levels of stress amongst pregnant women and new mothers. The current qualitative study explored the ways in which perinatal women made meaning of their experiences during the COVID-19 pandemic.

METHODS

Data came from a parent study in which 54 perinatal (pregnant and postpartum) women in the United States completed semi-structured interviews from October 2021 to January 2022 describing their experiences during the COVID-19 pandemic. The data was interpreted using a hermeneutic, phenomenological approach to delve deeply into the concept of meaning-making.

RESULTS

Despite high levels of stress and challenging circumstances, participants reported engaging in meaning-making through finding connection, focusing on gratitude, and identifying openings for change. Unique forms of meaning-making amongst this population include a sense of connection to women throughout history, connection to their baby, and recognition of the need for systemic change for perinatal women.

CONCLUSIONS

Perinatal women coped with the stress of the COVID-19 pandemic by making meaning from their experiences. Future research should further explore the importance of these aspects of meaning-making to perinatal women and implement these findings to adapt prevention and treatment approaches to address perinatal stress, especially during times of crisis.

The wonders of mind-body practices during pregnancy: A topical review

This topical review provides an up-to-date overview of the latest advancements in mind-body therapies in the gynaecological research field. It explores the various mind-body practices and their multifaceted benefits for expectant mothers during the transformative phase of pregnancy, including physical, emotional, and psychological aspects. The research highlights the importance of these practices in promoting maternal and fetal well-being. Prenatal yoga is found to enhance physical health, reduce discomfort, and lower stress and anxiety levels, potentially leading to shorter labour durations. Meditation is revealed to reduce stress and anxiety while nurturing emotional resilience. Prenatal Pilates improves musculoskeletal health and prepares mothers for labour, emphasising controlled movements and breathing techniques. Breathing techniques prove to be helpful for pregnant women in effectively managing pain during labour. Acupressure and reflexology offer non-pharmacological pain relief for common discomforts. Tai Chi improves physical fitness, flexibility, and mental well-being. This brief review, using evidence available from pre-clinical studies in physiological gynaecology literature, demonstrates the role of mind-body practices in enhancing the pregnancy journey, emphasising their integration into daily routines to contribute to overall well-being. By selecting the right practice or combination, expectant mothers can experience an overall better pregnancy.

Effects of relaxation interventions during pregnancy on maternal mental health, and pregnancy and newborn outcomes: A systematic review and meta-analysis

BACKGROUND

Stress during pregnancy is detrimental to maternal health, pregnancy and birth outcomes and various preventive relaxation interventions have been developed. This systematic review and meta-analysis aimed to evaluate their effectiveness in terms of maternal mental health, pregnancy and birth outcomes.

METHOD

The protocol for this review is published on PROSPERO with registration number CRD42020187443. A systematic search of major databases was conducted. Primary outcomes were maternal mental health problems (stress, anxiety, depression), and pregnancy (gestational age, labour duration, delivery mode) and birth outcomes (birth weight, Apgar score, preterm birth). Randomized controlled trials or quasi-experimental studies were eligible. Meta-analyses using a random-effects model was conducted for outcomes with sufficient data. For other outcomes a narrative review was undertaken.

RESULT

We reviewed 32 studies comprising 3,979 pregnant women aged 18 to 40 years. Relaxation interventions included yoga, music, Benson relaxation, progressive muscle relaxation (PMR), deep breathing relaxation (BR), guided imagery, mindfulness and hypnosis. Intervention duration ranged from brief experiment (~10 minutes) to 6 months of daily relaxation. Meta-analyses showed relaxation therapy reduced maternal stress (-4.1 points; 95% Confidence Interval (CI): -7.4, -0.9; 9 trials; 1113 participants), anxiety (-5.04 points; 95% CI: -8.2, -1.9; 10 trials; 1965 participants) and depressive symptoms (-2.3 points; 95% CI: -3.4, -1.3; 7 trials; 733 participants). Relaxation has also increased offspring birth weight (80 g, 95% CI: 1, 157; 8 trials; 1239 participants), explained by PMR (165g, 95% CI: 100, 231; 4 trials; 587 participants) in sub-group analysis. In five trials evaluating maternal physiological responses, relaxation therapy optimized blood pressure, heart rate and respiratory rate. Four trials showed relaxation therapy reduced duration of labour. Apgar score only improved significantly in two of six trials. One of three trials showed a significant increase in birth length, and one of three trials showed a significant increase in gestational age. Two of six trials examining delivery mode showed significantly increased spontaneous vaginal delivery and decreased instrumental delivery or cesarean section following a relaxation intervention.

DISCUSSION

We found consistent evidence for beneficial effects of relaxation interventions in reducing maternal stress, improving mental health, and some evidence for improved maternal physiological outcomes. In addition, we found a positive effect of relaxation interventions on birth weight and inconsistent effects on other pregnancy or birth outcomes. High quality adequately powered trials are needed to examine impacts of relaxation interventions on newborns and offspring health outcomes.

CONCLUSION

In addition to benefits for mothers, relaxation interventions provided during pregnancy improved birth weight and hold some promise for improving newborn outcomes; therefore, this approach strongly merits further research.

Effects of maternal stress and/or anxiety interventions in the first 1000 days:Systematic review of reviews

OBJECTIVE

Effective interventions are needed to mitigate effects of stress and anxiety from conception and up to two years postpartum (the first 1000 days), but it is unclear what works, for what populations and at what time points. This review aimed to synthesise evidence from existing reviews of the effects of stress and anxiety interventions.

METHODS

A systematic review of systematic reviews was conducted. PsycINFO, CINAHL, MEDLINE and the Cochrane databases were searched (inception to January 2020). Reviews were eligible if they examined effects of interventions during the first 1000 days on women's stress and/or anxiety. Extracted data were narratively synthesised. Review quality was assessed using existing recommendations including the AMSTAR tool .

RESULTS

Thirty-four reviews were eligible for inclusion; 21 demonstrated high methodological quality. Cognitive behavioural therapy demonstrates some beneficial effects for anxiety across the first 1000 days for general and at-risk populations. Support-based interventions demonstrate effects for stress and anxiety for at-risk mothers in the postpartum. Music, yoga and relaxation demonstrate some effects for stress and anxiety, but studies are limited by high risk of bias.

CONCLUSION

Existing evidence is inconsistent. Cognitive behavioural therapy and support-based interventions demonstrate some benefits. Further methodologically and conceptually robust research is needed.

Factors Associated with Prenatal Health Behaviors among Low-Income, Ethnic Minority Women

Less than one-third of pregnant women in the U.S. meet prenatal nutrition, exercise, and stress management health behavior guidelines. Low rates of these prenatal health behaviors have been especially observed among low-income, ethnic minority women, placing them and their infants at a disproportionally higher risk for health complications. Yet, few studies have identified factors associated with these prenatal health behaviors in this population. This study examined whether certain demographic (e.g., ethnicity) and psychosocial characteristics (i.e., coping, stress, pregnancy-specific stress, and depression) were associated with prenatal nutrition (i.e., high-fat food and fruit and vegetable intake), exercise, and stress management health behaviors in 100 low-income, pregnant women (39% African American, 30% foreign-born Latinas, 15% U.S.-born Latinas, 10% non-Hispanic white, and 6% Asian American/Pacific Islander) in southern California using an embedded, mixed-methods, cross-sectional design. Results demonstrated that ethnic minority women who experienced more stress and used more maladaptive coping strategies (e.g., avoidance) were particularly at risk of consuming more high-fat foods and engaging in less exercise and stress management during pregnancy. Qualitative responses revealed women's experiences with these prenatal health behaviors. These findings highlight the need for interventions and collaborative care models that target psychosocial factors in order to optimize prenatal health behaviors and health outcomes among ethnic minority women.

The effectiveness of skilled breathing and relaxation techniques during antenatal education on maternal and neonatal outcomes: a systematic review

BACKGROUND

Several studies have investigated the relationship between antenatal education classes and pregnancy outcomes. These studies have shown positive effects on mothers, such as a lower epidural rate in the intervention groups. However, until now, the impact on outcomes for mothers and newborns of antenatal education classes that focus on breathing and relaxation techniques has not been examined.

AIM

Investigate the effects of skilled breathing and relaxation techniques provided in antenatal education classes on maternal and neonatal birth outcomes.

METHODS

The protocol for this study was registered with PROSPERO (ID: CRD42020192289). A systematic literature search was undertaken and completed in January 2022, using the databases MEDLINE, CINAHL, clinicalTrials.gov, Cochrane Library, Embase and MIDIRS according to a priori formulated PICO criteria: population (pregnant women), intervention (antenatal education classes with integrated breathing and relaxation techniques), comparison (antenatal education classes that do not include skilled breathing and relaxation techniques), and outcome (maternal and neonatal outcomes). The quality of the studies was assessed by two reviewers using the standardised instruments RoB 2 and ROBINS-I.

RESULTS

Ten studies were included in this review, nine randomised controlled trials and one quasi-experimental study. The results indicate that skilled breathing and relaxation techniques may positively influence self-efficacy, the need for pharmacological support, specifically the use of epidural anaesthesia, and the memory of labour pain. No effects were found in relation to predefined neonatal outcomes. The quality of evidence on maternal and neonatal outcomes is inconsistent across studies, as different antenatal education classes with varying interventions, including breathing and relaxation techniques, were offered in the studies.

CONCLUSIONS

Women who attended an antenatal education class with breathing and relaxation techniques appear to benefit from the intervention. This applies to the practical implementation and use of breathing and relaxation techniques during labour, increased self-confidence and self-efficacy, and a increased feeling of being in control during labour. This demonstrates the importance of information provision and a focus on breathing and relaxation techniques in antenatal education.

The effectiveness of Jacobson's progressive muscle relaxation technique on maternal, fetal and neonatal outcomes in women with non-severe preeclampsia: a randomized clinical trial

Background

Preeclampsia (PE), as the most common major pregnancy disorder, has serious maternal, fetal and neonatal complications, and outcomes. The present study was designed to determine the effectiveness of Jacobson's progressive muscle relaxation technique on maternal, fetal, and neonatal outcomes in women with non-severe preeclampsia (PE).

Methods

This is a randomized clinical trial conducted from March 21, 2021 to July 22, 2021 in the Kamali referral center in Karaj, Iran. A total of 88 eligible participants were assigned to intervention and control groups (44 in each group) via blocked randomization. The intervention group (6 groups of 6 participants and one group of 8 participants) received Jacobson's progressive muscle relaxation technique in addition to receiving routine care, twice a week for 6 weeks (4 face-to-face sessions and 8 online sessions). The control group only received routine perinatal care. A checklist collected data before and after the intervention. Data were analyzed in SPSS software v.23. To analyze the obtained data, independent t-test, Paired t-test, Mann-Whitney, Chi-square, and Fisher test were used.

Results

The results showed a statistically significant difference between intervention and control groups in terms of Systolic Blood pressure (SBP) (P < 0.001), Diastolic Blood pressure (DBP) (P < 0.001), 24-hour urine protein level (proteinuria) (P < 0.001). and Fasting Blood Sugar (FBS) (P < 0.001), birth Weight (BW) (P = 0.01), baseline Fetal heart rate (BFHR) (P < 0.001) and Number fetal movements based on non-stress test (NFMsN), during 20 min (P < 0.001) after intervention (P < 0.001).

Also In the intervention group, the results showed a statistically significant difference in Amniotic Fluid Index (AFI) (P = 0.01), SBP(P < 0.001), DBP(P < 0.001), proteinuria (P < 0.001), FBS(P < 0.001), BFHR based on non-stress test (NST) (P < 0.001), and NFMsN during 20 min (P < 0.001) in the intervention group before and after the intervention. There was no statistically significant difference in the control group.

Conclusion

This study's results showed the effectiveness of progressive muscle relaxation technique on the improvement of SBP, DBP, proteinuria, FBS, FHR and NFMsN during 20 min based on NST and BW in women with non-severe PE. Therefore, it is recommended to perform this technique in health centers.

The effectiveness of psychoeducation interventions on prenatal attachment: A systematic review

OBJECTIVE

Positive prenatal attachment facilitates parental role adaptation and psychological adjustment during pregnancy, which is a significant predictor of postpartum attachment. The objective of this systematic review was to examine the effect of psychoeducation interventions on prenatal attachment of pregnant women and their partners.

DESIGN

Systematic literature searches of randomized controlled trials (RCTs) were conducted from January 2000 to January 2021, using databases: CINAHL, Embase, Medline, PsycInfo, PubMed, Web of Science and Cochrane Central Register of Controlled Trial and through hand-searching. Studies were independently selected by two reviewers, who also assessed the methodological quality of the included studies using the Cochrane Risk of Bias Tool. Narrative synthesis was conducted due to the significant clinical and methodological heterogeneity.

SETTING/PARTICIPANTS

Fifteen studies met the eligibility criteria for this review, among which 11 studies focused on pregnant women and four studies on their partners.

FINDINGS

The psychoeducation interventions in the included studies showed consistent favorable effects on prenatal attachment. Nine out of the 11 included studies showed statistical significant effects on maternal fetal attachment. Three out of the four studies reported significant effects favoring paternal fetal attachment.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

The preliminary evidence suggests that psychoeducation interventions have potential favorable effects on maternal fetal attachment and can enhance paternal fetal attachment. However, more studies are needed for investigating the effects of psychoeducation on paternal fetal attachment and for enhancing the validity of the evidence. Our review recommends that healthcare professionals to include psychoeducation as a part of their prenatal care for promoting prenatal attachment. Common characteristics of the interventions could act as references when designing psychoeducation programs for enhancing prenatal attachment.

Acute relaxation during pregnancy leads to a reduction in maternal electrodermal activity and self-reported stress levels

BACKGROUND

Prenatal maternal stress can have adverse effects on birth outcomes and fetal development. Relaxation techniques have been examined as potential countermeasures. This study investigates different relaxation techniques and their effect on self-reported stress levels and physiological stress levels in pregnant women.

METHODS

In this cross-sectional study, 38 pregnant women in their 30th to 40th gestational week were assigned to one of three, 20-min lasting relaxation groups: listening to music (N = 12), following a guided imagery (N = 12) or resting (N = 12). The intervention, i.e., acute relaxation (music, guided imagery or resting) took place once for each study participant. Study inclusion criteria were age over 18 years, German speaking, singleton and uncomplicated pregnancy during the 30th and 40th week of gestation. The stress levels were determined during the study. Current stress level during the study was assessed by a visual analogue scale. Chronic stress levels were assessed by the Trier Inventory of Chronic Stress and the Pregnancy Distress questionnaire. Multivariate analyses of covariance were performed and dependent measures included stress levels as well as physiological measures, i.e., cardiovascular activity (electrocardiogram) and skin conductance levels.

RESULTS

All three forms of relaxation led to reduced maternal stress which manifested itself in significantly decreased skin conductance, F(3,94) = 18.011, p = .001, η_p² = .365, and subjective stress levels after the interventions with no significant group difference. Post-intervention stress ratings were further affected by gestational age, with less subjective relaxation in women later in gestation, F (1, 34)=4.971, p = .032, η_p² = .128.

CONCLUSION

Independent of relaxation technique, single, 20-min relaxation intervention (music, guided imagery or resting) can significantly reduce maternal stress. Notably, women at an earlier stage in their pregnancy reported higher relaxation after the intervention than women later in gestation. Hence, gestational age may influence perceived stress levels and should be considered when evaluating relaxation or stress management interventions during pregnancy.

Strengthening Antenatal Care towards a Salutogenic Approach: A Meta-Ethnography

The aim was to explore how midwives, public health nurses and nurses view caring in antenatal care (ANC) as provided for mothers and fathers/partners. Based on Noblit and Hare (1988), meta-ethnography was used to address meaning by synthesizing knowledge and understanding inductively through selected qualitative studies (n = 16). Four core themes were identified: (1) supporting the parents to awaken to parenthood and creating a firm foundation for early parenting and their new life situation; (2) guiding parents on the path to parenthood and new responsibility; (3) ensuring normality and the bond between baby and parents while protecting life; and (4) promoting the health and wellbeing of the family today and in the future. The overarching theme can be expressed as "helping the woman and her partner prepare for their new life with the child by providing individualized, shared care, firmly grounded and with a view of the future". Caring in antenatal care (ANC) is being totally present, listening and using multidimensional professional competence but also being open-minded to new aspects and knowledge. The health promotion and positive health aspects should be considered an important part of supporting parents and the whole family now and in the future. A more conscious salutogenic approach to ANC would lead to more favorable results and could be a fruitful research topic in the future. There is a need to provide midwives/nurses with enough time to allow them to concentrate on specific needs and support for different kind of families in ANC but also training for midwives to make them more familiar with online and other options.

Relationship Between Fear of Childbirth and Psychological and Spiritual Well-Being in Pregnant Women

The aim of the study was to investigate the relationship between fear of childbirth (FOC) and psychological (PWB) and spiritual well-being (SWB) in pregnant women. Descriptive and relational study was conducted with 338 pregnant women in Turkey. Information form, Wijma Delivery Expectancy/Experience Questionnaire-A, Spiritual Well-Being Scale and Psychological Well-Being Scale were used for data collection. There was a negative correlation between SWB and PWB and FOC in pregnant women. SWB explained 18% of the variance related to FOC which increased to 24% with PWB. SWB was a partial mediating variable in PWB and FOC relationship. PWB and SWB of pregnant women should be evaluated in order to reduce FOC. PWB and SWB of pregnant women should be evaluated in order to reduce FOC.

Efficacy of psychotherapy for anxiety reduction in hospital management of women successfully treated for preterm labor: a randomized controlled trial

Preterm labor (PTL) is associated with high anxiety and stress in pregnant women. The study investigated the effect of adding psychotherapy to hospital management of pregnant women with successfully treated for PTLon improving anxiety, pregnancy stress, and perceived control. In a randomized controlled trial study, sixty pregnant women with gestational ages of 24 to 37 weeks and successfully treated forPTL were randomly divided into the experimental (n = 30) and control group (n = 30). The experimental group received psychotherapy along with medical care in individual face-to-facesessions, 1 h per day for 6 consecutive days.The control group received medical care for PTL. Objective outcomes were assessed via the State-Anxiety Inventory, Prenatal Distress Questionnaire (NuPDQ), and Perceived Pregnancy Control at pre-trial and post-trial. The results revealed that psychotherapy significantly improved mean pregnancy distress (45.80 ± 2.29 vs. 43.80 ± 1.93), state anxiety (47.46 ± 5.92 vs. 41.60 ± 5.46), and perceived control (2.86 ± 1.59 vs. 5.26 ± 1.38) in women with PTL from beginning to end of the intervention. The findings suggest that adding psychotherapy to hospital management of women successfully treated for PTLcan be considered a potential method to reduce anxiety and pregnancy-specific stress.

A systematic review: The effects of yoga on pregnancy

OBJECTIVE

A systematic review was conducted to update and provide a comprehensive overview on the psychological effects of antenatal yoga on pregnancy compared to standard prenatal care.

STUDY DESIGN

Four databases were searched using keywords "yoga", "pregnancy", "perinatal care", "prenatal care", "postnatal care", "postpartum period", "peripartum period", "patient outcome assessment", "outcome assessment", "pregnancy outcome", "treatment outcome". Trials were considered if they were randomized controlled trials (RCTs) published from 2011 to 2018 and evaluated an antenatal yoga intervention. All studies were assessed for risk of bias using the Cochrane criteria. Trial characteristics and outcomes were extracted and synthesized descriptively where possible. Due to heterogeneity, meta-analysis was not possible.

RESULTS

Of the 175 non-duplicated studies, 16 met criteria for full-text review. Five RCTs met the inclusion criteria and were included in the systematic review. The findings of the RCTs suggest antenatal yoga may be safe and may effectively decrease stress levels, anxiety scores, depression scores, and pain response as well as increasing maternal immunity and emotional-wellbeing.

CONCLUSION

Yoga appears to be safe and may improve psychological and pregnancy outcomes. However, due to the limited number of studies, more high-quality, large RCTs are needed to draw conclusions about improvement in other pregnancy outcomes.

The Effectiveness of Group-based Cognitive Hypnotherapy on the Psychological Well-being of Patients with Multiple Sclerosis: A Randomized Clinical Trial

Multiple sclerosis is a chronic, demyelinating disease of the central nervous system mainly affecting young adults. In addition to physical problems, the patients suffer from many psychological problems affecting their psychological well-being. The aim of the present study was to determine the effectiveness of group-based cognitive hypnotherapy on the psychological well-being of patients suffering from multiple sclerosis. This study was designed as a clinical trial with a pretest-posttest control group. From 60 patients diagnosed with multiple sclerosis referred to Beheshti hospital in Yasuj, Iran, 45 patients who met the inclusion criteria were selected by the convenience sampling method. The patients were randomly assigned to intervention (23 individuals) and control (22 individuals) groups through stratified random allocation. After completing the Ryff Scales of Psychological Well-Being, the intervention group attended eight sessions of group-based cognitive hypnotherapy on a weekly basis. The control group did not attend any intervention sessions. At the end of the eight intervention sessions, both groups completed the Ryff's Scale of Psychological Well-being again. The collected data were analyzed using the SPSS software (Version 23). Analysis of Covariance (ANCOVA) and two-way Analysis of variance (ANOVA) tests were used in order to compare the groups. The results indicated that cognitive hypnotherapy had a significant effect on the total score of psychological well-being (F (45, 1) = 6.07, p = .018, η2 = 0.12) and the dimension of environmental mastery (p < .05). Therefore, it is recommended to use hypnotherapy to promote the psychological well-being of patients suffering from multiple sclerosis.

Spotlight on the fetus: how physical activity during pregnancy influences fetal health: a narrative review

Before and during pregnancy, women often aim to improve their lifestyle so as to provide a healthier environment for their developing child. It remains unresolved, however, as to whether physical activity (PA) during pregnancy poses a possible risk or whether it might even have beneficial effects on the developing child. There is increasing evidence that PA during pregnancy is indeed beneficial to maternal physiological and psychological health and that it is generally not detrimental to the fetal cardiovascular system and neuronal function in the developing child. This also led to international recommendations for PAs during pregnancy. In the current review, we aimed to comprehensively assess the evidence of beneficial and harmful effects of maternal PA, including high-performance sports, on fetal development. The different mental and body-based relaxation techniques presented here are frequently performed during pregnancy. We found a considerable number of studies addressing these issues. In general, neither low key, moderate maternal PA nor relaxation techniques were observed to have a harmful effect on the developing child. However, we identified some forms of PA which could have at least a transient unfavourable effect. Notably, the literature currently available does not provide enough evidence to enable us to make a general conclusive statement on this subject. This is due to the lack of longitudinal studies on the metabolic and cognitive effects of regular PA during pregnancy and the wide diversity of methods used. In particular, the kind of PA investigated in each study differed from study to study.

Maternal distress, HPA activity, and antenatal interventions: A systematic review

BACKGROUND

Elevated antenatal distress has been associated with negative outcomes for both mothers and, as a result, their infants. One mechanism hypothesised to underlie these associations is the maternal hypothalamic pituitary adrenal (HPA) axis. Though research has examined whether biopsychosocial antenatal interventions can reduce maternal HPA activity, only one review has summarized the nature of findings to date. The present study examined randomised control trials (RCTs) specifically; our primary aim was to assess the effectiveness of antenatal interventions in reducing HPA activity in pregnant women, our secondary aim was to examine whether antenatal interventions reduced maternal self-report of depression and/or anxiety.

METHODS

This study systematically reviewed RCTs that evaluated biopsychosocial interventions that reported subjective and objective markers of maternal distress in pregnant women within the clinical population.

RESULTS

Eight studies met inclusion criteria and women were in their second or third trimester. HPA-activity was primarily assessed through salivary cortisol (n = 7) and self-reported maternal distress was assessed using a variety of validated screening measures. Included trials demonstrated significant methodological heterogeneity and small sample sizes, poor treatment adherence, and poor reliability in cortisol measurement indicated low methodological quality.

CONCLUSIONS

Due to the high heterogeneity across studies, small sample sizes, and unreliable sampling methods, firm conclusions about the efficacy and effectiveness of antenatal interventions cannot be drawn. Despite this, interventions which targeted pregnancy-specific influencers of maternal mood were more likely to result in reduced depression and anxiety symptomatology as reported by mothers.

Bedside Music Therapy for Women during Antepartum and Postpartum Hospitalization

PURPOSE

Stress and anxiety are prevalent during pregnancy and postpartum with adverse effects on mothers and newborns, yet women's psychological and emotional needs are often given a lower priority than their physical wellbeing. The purpose of this study was to assess feasibility of implementing a bedside music therapy intervention to alleviate stress and anxiety, provide emotional support, and facilitate mother-baby bonding for women during antepartum and postpartum hospitalization at a large urban medical center.

STUDY DESIGN AND METHODS

Over 15 months, women on three units who were hospitalized during antepartum or postpartum were referred for music therapy and received a single bedside session from a credentialed music therapist (MT-BC), including tailored interventions and education in relaxation techniques. A retrospective analysis of postintervention feedback questionnaires and process notes was conducted to assess participant receptivity and satisfaction, and the feasibility of implementing the program on the units.

RESULTS

Music therapy was provided to 223 postpartum and 97 antepartum patients. The program was found to be feasible and well received, including high satisfaction, positive effects on participants' relaxation and sense of connection with their baby, and enthusiastic reception from providers and staff. Qualitative feedback revealed salient themes including the effect of the intervention on mothers' mental, emotional and physical states, and the soothing effect of music on their newborns.

CLINICAL IMPLICATIONS

Hospitals are in a unique position to provide support services and self-care education for women during their antepartum and postpartum hospitalization. Music therapy can be integrated successfully into inpatient care as a nurturing and patient-centered form of psychosocial support.

Perinatal anxiety: approach to diagnosis and management in the obstetric setting

Anxiety is common in women during the perinatal period, manifests with various symptoms and severity, and is associated with significant maternal morbidity and adverse obstetric and neonatal outcomes. Given the intimate relationship and frequency of contact, the obstetric provider is positioned optimally to create a therapeutic alliance and to treat perinatal anxiety. Time constraints, absence of randomized controlled trials, mixed quality of data, and concern for potential adverse reproductive outcomes all limit the clinician's ability to initiate informed risk-benefit discussions. Clear understanding of the role of the obstetric provider in the identification, stabilization, and initiation of medication and/or referral to psychotherapy for women with perinatal anxiety disorders is critical to maternal and neonatal wellbeing. Informed by our clinical practice as perinatal psychiatric providers, we have provided a concise summary of current research on the approach to the treatment of perinatal anxiety disorders in the obstetric setting that includes psychotherapy and supportive interventions, primary and adjuvant psychiatric medication, and general prescribing pearls. Medications that we examined include antidepressants, benzodiazepines, sedative-hypnotics, antihistamines, quetiapine, buspirone, propranolol, and melatonin. Further research into management of perinatal anxiety, particularly psychopharmacologic management, is warranted.

Comparing the Effects of Progressive Muscle Relaxation and Physical Activity on Pregnant Women's General Health

Background:

Pregnancy is important because maternal health and well-being directly affects another person's life. This study aimed to compare the effects of progressive muscle relaxation (PMR) and physical activity (PA) on the general health of pregnant women.

Materials and Methods:

This randomized clinical trial was conducted among 96 primiparous women enrolled in a prenatal clinic in Tehran (Iran) between May 3, 2013 and August 7, 2013. The participants were selected through convenience sampling over 3 weeks and randomly assigned to the PMR, PA, and control groups, comprising 32 participants each. Six participants did not complete the follow-up measurement (N = 90). The PMR group underwent three sessions of 1.5–2 h in theoretical and practical training, and in the PMR group, training was given in groups of three to four persons. Both groups performed exercises at home for 8 weeks and recorded them in daily report sheets. The general health of all three groups was assessed before and after intervention by using the General Health Questionnaire-28.

Results:

Differences in the mean (SD) general health scores obtained before and after intervention in the PMR, PA, and control groups were 15.63 (5.73), 19.11 (7.79), and 8.27 (2.14), respectively. One-way analysis of variance test showed a significant difference between the three groups (F = 28.10; p < 0.001).

Conclusions:

As the study results confirm the positive effects of PMR and PA on the subscales of the general health of pregnant women, the two techniques are recommended to promote the general health of pregnant women.

Exploring factors behind pregnant women's quality of life in Iran: a qualitative study

BACKGROUND AND OBJECTIVE

Pregnancy-related physiologic and psychosocial alterations can impact on the body and cause symptoms which may affect quality of life. Since qualitative studies can provide more in-depth understanding of quality of life and its determining factors, this study was conducted with the aim of exploring factors affecting pregnant women's quality of life.

METHODS

A qualitative descriptive study with conventional content analysis approach was made using the conventional content analysis approach on a purposeful sample of sixteen pregnant Iranian women in Hamadan, Iran from May 2015 to December 2015. Sampling was continued until data saturation. Data were collected through in-depth semi-structured personal interviews, and were analyzed using the conventional content analysis approach.

RESULTS

Data analysis resulted in three main categories, namely, the effects of pregnancy on different aspects of health (including psychological disorders, impaired interactions, disturbances in doing daily activities, disturbed body image, alterations in sexual relationships, physical disorders, and alterations in dietary habits and treatment regimens), pregnancy-related concerns (regarding the gender of the fetus, financial problems, childbirth, health, and the future), and coping with pregnancy (through strategies such as spirituality, positive attitude toward pregnancy, distraction and imagination, and support).

CONCLUSIONS

This study showed that different factors can affect pregnant women's quality of life. Nonetheless, prenatal care services are mainly focused on pregnancy-related physical problems, and other aspects of care are usually taken for granted. Consequently, healthcare professionals need to pay greater attention to pregnant women's quality of life and its contributing factors.

Cumulative effects of prenatal-exposure to exogenous chemicals and psychosocial stress on fetal growth: Systematic-review of the human and animal evidence

BACKGROUND

Adverse effects of prenatal stress or environmental chemical exposures on fetal growth are well described, yet their combined effect remains unclear.

OBJECTIVES

To conduct a systematic review on the combined impact and interaction of prenatal exposure to stress and chemicals on developmental outcomes.

METHODS

We used the first three steps of the Navigation Guide systematic review. We wrote a protocol, performed a robust literature search to identify relevant animal and human studies and extracted data on developmental outcomes. For the most common outcome (fetal growth), we evaluated risk of bias, calculated effect sizes for main effects of individual and combined exposures, and performed a random effects meta-analysis of those studies reporting on odds of low birthweight (LBW) by smoking and socioeconomic status (SES).

RESULTS

We identified 17 human- and 22 animal-studies of combined chemical and stress exposures and fetal growth. Human studies tended to have a lower risk of bias across nine domains. Generally, we found stronger effects for chemicals than stress, and these exposures were associated with reduced fetal growth in the low-stress group and the association was often greater in high stress groups, with limited evidence of effect modification. We found smoking associated with significantly increased odds of LBW, with a greater effect for high stress (low SES; OR 4.75 (2.46-9.16)) compared to low stress (high SES; OR 1.95 (95% CI 1.53-2.48)). Animal studies generally had a high risk of bias with no significant combined effect or effect modification.

CONCLUSIONS

We found that despite concern for the combined effects of environmental chemicals and stress, this is still an under-studied topic, though limited available human studies indicate chemical exposures exert stronger effects than stress, and this effect is generally larger in the presence of stress.

Prenatal and adult androgen activities in alcohol dependence

OBJECTIVE

Alcohol dependence is more prevalent in men than in women. The evidence for how prenatal and adult androgens influence alcohol dependence is limited. We investigated the effects of prenatal and adult androgen activity on alcohol dependence. Moreover, we studied how the behaviours of pregnant women affect their children's prenatal androgen load.

METHOD

We quantified prenatal androgen markers (e.g., second-to-fourth finger length ratio [2D : 4D]) and blood androgens in 200 early-abstinent alcohol-dependent in-patients and 240 controls (2013-2015, including a 12-month follow-up). We also surveyed 134 women during pregnancy (2005-2007) and measured the 2D : 4D of their children (2013-2016).

RESULTS

The prenatal androgen loads were higher in the male alcohol-dependent patients compared to the controls (lower 2D : 4D, P = 0.004) and correlated positively with the patients' liver transaminase activities (P < 0.001) and alcohol withdrawal severity (P = 0.019). Higher prenatal androgen loads and increasing androgen levels during withdrawal predicted earlier and more frequent 12-month hospital readmission in alcohol-dependent patients (P < 0.005). Moreover, stress levels (P = 0.002), alcohol (P = 0.010) and tobacco consumption (P = 0.017), and lifetime stressors (P = 0.019) of women during pregnancy related positively to their children's prenatal androgen loads (lower 2D : 4D).

CONCLUSION

Androgen activities in alcohol-dependent patients and behaviours of pregnant women represent novel preventive and therapeutic targets of alcohol dependence.

A Program Aimed at Reducing Anxiety in Pregnant Women Diagnosed With a Small-for-Gestational-Age Fetus: Evaluative Findings From a Spanish Study

The objective of this study was to evaluate the effect of anxiety-reducing techniques including music therapy, sophrology, and creative visualization in pregnant women with a fetus diagnosed as small for gestational age and improved fetal and neonatal weight. This was a quasi-experimental study with a nonrandomized clinical trial design. We compared 2 groups of pregnant women with a fetus diagnosed as small for gestational age with no abnormalities on Doppler studies. The control group (n = 93) received standard care, and the intervention group (n = 65), in addition to standard care, underwent a program of 6 sessions led by a midwife or nurse who taught anxiety-reduction techniques. The State-Trait Anxiety Inventory (STAI) including trait and state subscales were completed by both groups at the start of the study, and only the STAI-State subscale was completed again at the end of the study. Comparisons between the 2 groups regarding fetal weight and centile and maternal STAI scores were performed using the t test and the χ test. There were no significant differences in the STAI-Trait scores between the 2 groups. There were statistically significant differences in the intervention group's STAI-State score percentiles between the start and the end of the study, being lower at the end of the study (P < .001). There were significant differences between the 2 groups in fetal weight trajectory on the basis of fetal weight: the intervention group had a larger weight gain (P < .005). The program designed to reduce anxiety in pregnant women was effective at reducing anxiety in the women in the intervention group, leading to a favorable fetal weight trajectory in this group.

A prospective-longitudinal study on the association of anxiety disorders prior to pregnancy and pregnancy- and child-related fears

This study aimed to investigate the relation between anxiety disorders prior to pregnancy and specific pregnancy- and child-related fears during pregnancy and after delivery. 306 expectant mothers were interviewed regarding anxiety (and depressive) disorders prior to pregnancy and pregnancy- and child-related fears (e.g. fear of labor pain, fear of infant injury) using the Composite International Diagnostic Interview for Women (CIDI-V). Pregnancy- and child-related fears were particularly pronounced in women with multiple anxiety disorders and women with comorbid anxiety and depressive disorders prior to pregnancy. Further analyses revealed associations between particular anxiety disorders and specific pregnancy- and child-related fears. Results remained stable when considering potential confounders such as maternal age, education, marital status, parity, prior abortion and preterm delivery or low birth weight. Our study suggests that especially women with multiple anxiety and/or comorbid depressive disorders may benefit from early targeted interventions to prevent an escalation of anxiety and fears over the peripartum period.

Perinatal Music Therapy and Antenatal Music Classes: Principles, Mechanisms, and Benefits

Antenatal music activities are in the ascendant. Regarding evidence-based research, the article advocates 5 main aims: music therapeutic control of pre- and perinatal stress, anxiety, and depression; music-related mental and physical birth preparation comprising cognitive adjustment, emotional regulation, physical activity, relaxation and pain management, and social inclusion; music-associated bonding and self-efficacy; prenatal sound stimulation to trigger learning processes, pedagogical priming and brain maturation; music activities to facilitate the child's acculturation and adaptive self-regulation. Underlying mechanisms such as neuroplasticity help to understand the multifaceted effects of music in pre- and perinatal care. Individual conditions and features of the mother and her child have to be taken into account and music interventions to be harmonized with complementary perinatal programs.

Group psychoeducation with relaxation for severe fear of childbirth improves maternal adjustment and childbirth experience--a randomised controlled trial

BACKGROUND

Previous studies on the treatment of women with fear of childbirth have focused on the delivery mode. Women with fear of childbirth often suffer from anxiety and/or depression, and treatment therefore also needs to target postnatal psychological well-being and the early mother-infant relationship.

METHODS

Three hundred and seventy-one nulliparous women out of 4575 scored ≥100 in prospective screening (Wijma Delivery Expectancy Questionnaire, W-DEQ-A), indicating severe fear of childbirth. These women were randomised to psychoeducative group intervention with relaxation (n = 131; six sessions during pregnancy, one postnatal) or to conventional care (n = 240) by community nurses (referral if necessary). Psycho-emotional and psychosocial evaluations [Edinburgh Postnatal Depression Scale (EPDS), social support, Maternal Adjustment and Attitudes (MAMA), Traumatic Events Scale (TES) and the Wijma Delivery Experience Questionnaire (W-DEQ-B)] were completed twice during pregnancy and/or 3 months postpartum.

RESULTS

Postnatal maternal adjustment (MAMA mean score 38.1 ± 4.3 versus 35.7 ± 5.0, p = 0.001) and childbirth experience (mean W-DEQ-B sum score 63.0 ± 29 versus 73.7 ± 32, p = 0.008) were better in the intervention group compared with controls. In hierarchical regression, social support, participating in intervention, and less fearful childbirth experience predicted better maternal adjustment. The level of postnatal depressive symptoms was significantly lower in the intervention group (mean sum score 6.4 ± 5.4 versus 8.0 ± 5.9 p = 0.04). There were no differences in the frequency of post-traumatic stress symptoms between the groups.

CONCLUSIONS

In nulliparous women with severe fear of childbirth, participation in a targeted psychoeducative group resulted in better maternal adjustment, a less fearful childbirth experience and fewer postnatal depressive symptoms, compared with conventional care.

Risk factors and course patterns of anxiety and depressive disorders during pregnancy and after delivery: a prospective-longitudinal study

BACKGROUND

Peripartum anxiety and depressive disorders are associated with adverse consequences for mother and child. Thus, it is important to examine risk factors, correlates and course patterns of anxiety and depressive disorders during pregnancy and after delivery.

METHODS

In the prospective-longitudinal Maternal Anxiety in Relation to Infant Development (MARI) Study, n=306 expectant mothers were recruited from gynaecological outpatient settings in Germany and completed up to seven waves of assessment from early pregnancy until 16 months postpartum. Anxiety and depressive disorders and potential risk factors/correlates were assessed with the Composite International Diagnostic Interview for Women (CIDI-V), medical records and additional questionnaires.

RESULTS

Although peripartum anxiety and depressive disorders appeared to be persistent in some women, others reported major changes with heterogeneous courses and shifts between diagnoses and contents. There was a considerable amount of incident disorders. Strongest predictors for peripartum anxiety and depressive disorders were anxiety and depressive disorders prior to pregnancy, but psychosocial (e.g. maternal education), individual (e.g. low self-esteem), and interpersonal (e.g. partnership satisfaction, social support) factors were also related.

LIMITATION

Knowing the aims of the study, some participants may have been more encouraged to report particular symptoms, but if so, this points to the importance of a comprehensive assessment in perinatal care.

CONCLUSION

Peripartum time is a sensitive period for a considerable incidence or persistence/recurrence of anxiety and depressive disorders albeit the course may be rather heterogeneous. Interventional studies are needed to examine whether an alteration of associated factors could help to prevent peripartum anxiety and depressive disorders.

Internet-based stress management for women with preterm labour--a case-based experience report

Pregnant women with preterm labour (PTL) in pregnancy often experience increased distress and anxieties regarding both the pregnancy and the child's health. The pathogenesis of PTL is, among other causes, related to the stress-associated activation of the maternal-foetal stress system. In spite of these psychobiological associations, only a few research studies have investigated the potential of psychological stress-reducing interventions. The following paper will present an online anxiety and stress management self-help program for pregnant women with PTL. Structure and content of the program will be illustrated by a case-based experience report. L.B., 32 years (G3, P1), was recruited at gestational week 27 while hospitalized for PTL for 3 weeks. She worked independently through the program for 6 weeks and had regular written contact with a therapist. Processing the program had a positive impact on L.B.'s anxiety and stress levels, as well as on her experienced depressive symptoms and bonding to the foetus. As PTL and the risk of PTB are associated with distress, psychological stress-reducing interventions might be beneficial. This study examines the applicability of an online intervention for pregnant women with PTL. The case report illustrates how adequate low-threshold psychological support could be provided to these women.

Early intervention in pregnant women with elevated anxiety and depressive symptoms: efficacy of a cognitive-behavioral group program

To examine whether a cognitive-behavioral group program among pregnant women with elevated levels of anxiety or depression may reduce anxious and depressive symptoms and has a positive impact on risk factors for anxiety disorders and depression. A total of 753 participants were recruited. After completion of the clinical standardized interview, 160 participants were randomized to an intervention group or a control condition. Psychometric assessments took place at T1 (preintervention), T2 (antenatal follow-up), and T3 (3 months postpartum). Analyses included women who took part in all 3 assessments (intervention group, N = 21; control group, N = 53). The subjective program evaluation by the participants was highly positive, but with the exception of a short-term effect on the quality of an intimate partnership (F1/67 = 4.056; P < .05], intervention effects on anxiety or depressive symptoms were not found. However, there was an intervention effect 3 months postpartum for participants with high depressive symptoms at T1 (Edinburgh Postnatal Depression Scale score of ≥10) (F1/69 = 5.410; P < .05). The results argue against a general efficacy of a cognitive-behavioral group program for pregnant women with rather low levels of anxiety and depression. For women with higher depressive symptoms during pregnancy, a cognitive-behavioral group program may have a positive impact on the course of depressive symptoms during the postpartum period.

Effects of Progressive Muscle Relaxation Exercises Accompanied by Music on Low Back Pain and Quality of Life During Pregnancy

INTRODUCTION

Back pain is commonly experienced by pregnant women. Evidence suggests that progressive muscle relaxation (PMR) therapy, a complementary therapy widely used by pregnant women, may improve the physical and psychological outcomes of pregnancy. The aim of this study was to investigate the effects of PMR training accompanied by music on perceived pain and quality of life (QOL) in pregnant women with low back pain (LBP).

METHODS

This was a prospective randomized controlled trial. The study was designed to examine the effects of PMR accompanied by music on pregnant women with LBP. In total, 66 pregnant women were assigned randomly to a PMR group or a control group (33 women in each). A personal information form was used as a data collection tool; a visual analog scale was used for measuring pain; and the Short Form-36 was used to evaluate QOL.

RESULTS

The control and intervention groups were comparable at baseline. Significant differences were observed between the 2 groups after 4 and 8 weeks of intervention. The intervention group showed significant improvement in all QOL subscales after the intervention. The intervention group, but not the control group, showed significant improvement in perceived pain after the intervention. The intervention group experienced a greater decrease in perceived pain and improved QOL than the control group.

DISCUSSION

Our findings show that PMR accompanied by music may be an effective therapy for improving pain and QOL in pregnant women with LBP. Large randomized studies are recommended to confirm these results.

Sleep quality and stress in women with pregnancy-induced hypertension and gestational diabetes mellitus

BACKGROUND

Pregnant women with complications including pregnancy-induced hypertension (PIH) and gestational diabetes mellitus (GDM) often experience disrupted sleep patterns because of activation of the sympathetic nervous system. These pathologies are aggravated by sympathetic nervous system activation and may be related to stress. The present study aimed to clarify the characteristics of and changes in sleep quality and stress in pregnant women with PIH and GDM during the second and third trimesters.

METHODS

We enrolled 56 women in their second or third trimesters who were diagnosed with PIH or GDM. Participants completed questionnaires, including the Pittsburgh Sleep Quality Index (PSQI) and the Perceived Stress Scale (PSS). Secretory immunoglobulin A (SlgA) concentrations were measured as a biological indicator of stress.

RESULTS

PSS scores and subjective stress parameters were significantly higher than those reported from previous studies of healthy pregnant women (15.2 points and 15.1 points for the second and third trimesters, respectively). Mean one-day values for SIgA were 168.3 and 205.7 μg/mL for the second and third trimesters, respectively. During the second and third trimesters, SIgA scores were higher than those reported for healthy pregnant women in previous studies. The PSQI component scores sleep disturbance (C5) and sleep duration (C3) in follow up case were significantly higher in the third trimester than in the second trimester.

DISCUSSION

This investigation suggests that pregnant women with PIH and GDM experience higher stress levels than do non-pregnant women and healthy pregnant women. Further, our results indicate that sleep quality worsens during the third trimester compared with the second trimester.
