Non-pharmacological interventions for improving postpartum maternal sleep: A systematic review and meta-analysis

Diagnosis and management of common sleep disorders during the perinatal period

The perinatal period is a critical phase in a woman's life characterized by significant physical, emotional, and societal changes. Sleep disorders such as insomnia, restless legs syndrome, obstructive sleep apnea, and poor sleep quality have been observed to increase in prevalence during the perinatal period. Given the harmful impact of sleep disturbances on the health of both mother and newborn, it is crucial to diagnose and treat them promptly. There is a paucity of literature on sleep problems during the perinatal period. This narrative review aimed to summarize the existing evidence and provide suggestions for promptly identifying and managing these disorders.

Maternal Sleep Health, Social Support, and Distress: A Mixed-Methods Analysis of Mothers of Infants and Young Children in Rural US

OBJECTIVES

The purpose of this study was to explore sleep health in rural maternal populations through a social-ecological framework and identify risk and protective factors for this population.

METHODS

39 individuals who are mothers of infants or children under the age of 5 years completed an online survey, 35 of which completed a subsequent semi-structured interview. Recruitment was limited to one rural community and was in partnership with community healthcare providers. Results were integrated using a convergent, parallel mixed-methods design.

RESULTS

Poor sleep health and high prevalence of insomnia symptoms in rural mothers were evident and associated with social support and maternal distress. Qualitative content from interviews indicated that well-established precipitating and perpetuating factors for insomnia may contribute to poor maternal sleep health. Results also revealed a gap in knowledge and language surrounding sleep health among rural mothers.

CONCLUSIONS

Sleep health is challenged during the transition to motherhood and rural mothers have less access to specialized perinatal and behavioral health care than their urban counterparts. In this sample, poor sleep was attributable to distress in addition to nocturnal infant and child sleep patterns which has implications for psychoeducation and promotion of sleep health in mothers. Sleep is a modifiable health indicator that is associated with several other maternal health outcomes and should be considered an element of a comprehensive maternal health for prevention and intervention across individual, interpersonal, and societal domains of the social-ecological model of sleep health.

Longitudinal assessment of sleep and fatigue according to baby feeding method in postpartum women: a prospective observational study

BACKGROUND

Poor subjective sleep quality, depressive symptoms and fatigue occur frequently in postpartum. However, the dynamics of their respective associations from prepartum throughout the maternity period in function of baby feeding method have not been fully elucidated.

METHODS

Prospective, longitudinal study using validated questionnaires probing for sleep quality, insomnia, fatigue and depressive symptoms at 35-37 weeks of gestation and at 2, 8 and 12 weeks postpartum in the obstetric departments of two Flemish hospitals. Somers'd ordinal correlation was used for correlations between the results of questionnaires (ratio variables) and the feeding method variable (an ordinal variable); T tests (normal data) or Mann Whitney (non normal data) tests for equality of means; ordinal regression ('Proportional odds model') to investigate the predictive value of parameters at one moment on the feeding method choice at a later moment; logistic regression to investigate the predictive value of parameters on later change of feeding method.

RESULTS

188 women indicating a choice for either bottle or breastfeeding in prepartum (27-35 weeks' gestation) were included. Higher fatigue assessed through the Fatigue Severity Scale within late pregnancy was moderately associated with primary bottle feeding choice. Fatigue decreased at early and late postpartum in bottle feeding (-0.38 ± 1.04; p = .110 and - 0.31 ± 1.01; p = .642 respectively), but remained unchanged from late pregnancy through early and late postpartum in breastfeeding (0.04 ± 1.21; p = .110 and - 0.27 ± 0.96; p = .642 respectively), resulting in similar fatigue in both feeding methods in early through late postpartum. There were no differences in sleep quality or insomnia symptoms at all time points. Presence of postpartum depressive symptoms were associated with early switching to bottle feeding (Somers' d correlation 0.11 (p = .021).

CONCLUSIONS

Fatigue and depressive symptoms are inversely associated with breastfeeding initiation or maintenance and influence feeding method dynamics.

A multilevel developmental psychopathology model of childbirth and the perinatal transition

Despite recent applications of a developmental psychopathology perspective to the perinatal period, these conceptualizations have largely ignored the role that childbirth plays in the perinatal transition. Thus, we present a conceptual model of childbirth as a bridge between prenatal and postnatal health. We argue that biopsychosocial factors during pregnancy influence postnatal health trajectories both directly and indirectly through childbirth experiences, and we focus our review on those indirect effects. In order to frame our model within a developmental psychopathology lens, we first describe "typical" biopsychosocial aspects of pregnancy and childbirth. Then, we explore ways in which these processes may deviate from the norm to result in adverse or traumatic childbirth experiences. We briefly describe early postnatal health trajectories that may follow from these birth experiences, including those which are adaptive despite traumatic childbirth, and we conclude with implications for research and clinical practice. We intend for our model to illuminate the importance of including childbirth in multilevel perinatal research. This advancement is critical for reducing perinatal health disparities and promoting health and well-being among birthing parents and their children.

Effectiveness of preoperative multimedia educational sessions on the levels of anxiety and satisfaction among women undergoing cesarean: a systematic review and meta-analysis

This systematic review and meta-analysis aimed to explore the effectiveness of preoperative multimedia educational sessions on the levels of anxiety and satisfaction among women undergoing cesarean section (CS). The Scopus, PubMed, and Cochrane databases were searched without language limitations for eligible randomized controlled trials (RCTs) published from their inception up to October 15, 2023. A random-effect meta-analysis was conducted, and the quality of this meta-analysis was evaluated using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach. Seven RCTs (n = 1006 women) met the inclusion criteria. Preoperative multimedia sessions were found to significantly reduce anxiety levels (n = 6 RCTs, weighted mean difference: -3.10; 95 percent confidence intervals (CI): -4.48, -1.73; I2 = 44.24 percent, moderate certainty of evidence) compared to the control group. However, there was no significant difference between the two groups regarding women's satisfaction after surgery (n = 5 RCTs, risk ratio: 1.37; 95 percent CI: 0.76, 2.50; I2 = 98.26 percent, moderate certainty of evidence). Leave-one-out sensitivity analysis showed robustness of the outcomes. The findings of this meta-analysis suggest that providing multimedia educational programs before surgery could potentially have a beneficial effect on the levels of anxiety experienced by women undergoing CS. However, it is imperative to validate these results through larger samples and multi-centered RCTs.

Effect of intraoperative and/or postoperative esketamine administration on preventing postpartum depression: A systematic review and meta-analysis

This systematic review and meta-analysis aimed to evaluate the impact of intraoperative and/or postoperative esketamine application on the prevention of postpartum depression (PPD). PubMed, Embase, and Web of Science were thoroughly searched for eligible randomized controlled trials (RCTs) regarding the application of esketamine for postnatal depression prevention. Nine RCTs including 1277 participants were involved in the final analysis. It was found that intraoperative and/or postoperative administration of esketamine significantly reduced the PPD incidence and the Edinburgh Postnatal Depression Scores in the early postoperative period. Meanwhile, esketamine lowered the occurrence of postoperative nausea and vomiting with no influence on other psychiatric symptoms.

Opportunities in the Postpartum Period to Reduce Cardiovascular Disease Risk After Adverse Pregnancy Outcomes: A Scientific Statement From the American Heart Association

Adverse pregnancy outcomes are common among pregnant individuals and are associated with long-term risk of cardiovascular disease. Individuals with adverse pregnancy outcomes also have an increased incidence of cardiovascular disease risk factors after delivery. Despite this, evidence-based approaches to managing these patients after pregnancy to reduce cardiovascular disease risk are lacking. In this scientific statement, we review the current evidence on interpregnancy and postpartum preventive strategies, blood pressure management, and lifestyle interventions for optimizing cardiovascular disease using the American Heart Association Life's Essential 8 framework. Clinical, health system, and community-level interventions can be used to engage postpartum individuals and to reach populations who experience the highest burden of adverse pregnancy outcomes and cardiovascular disease. Future trials are needed to improve screening of subclinical cardiovascular disease in individuals with a history of adverse pregnancy outcomes, before the onset of symptomatic disease. Interventions in the fourth trimester, defined as the 12 weeks after delivery, have great potential to improve cardiovascular health across the life course.

Let's Talk about Sleep Baby: Sexual Activity Postpartum and Its Links with Room Sharing, Parent Sleep, and Objectively Measured Infant Sleep and Parent Nighttime Crib Visits

The postpartum period may pose a considerable challenge for both parent sleep and sexual activity. This study assessed the links between partnered sexual frequency and satisfaction postpartum and parent sleep, infant sleep, parent nighttime caregiving, and parent-infant room sharing. Participants were 897 parents of infants aged 1-18-months (M = 8.8 ± 4.3, 49% girls). Parents completed an online survey about their sexual frequency and satisfaction, sleep, relationship satisfaction, depression, and demographic characteristics. Infant sleep and parent nighttime crib visits were measured objectively using auto-videosomnography during 2-weeks, with 8,460 nights assessed. Results indicated that the frequency of partnered sexual activity was 3.8 ± 4.2 times per month. Frequency of sexual activity increased with infant age, yet increases beyond the first 6 months postpartum were non-significant. Adjusted GEE modeling revealed that more parent nighttime crib visits were significantly associated with lower sexual frequency, regardless of infant age. Other parent and infant sleep-related factors were not significantly linked with sexual frequency in adjusted models. Moreover, sexual satisfaction was not associated with parent nighttime caregiving, parent or infant sleep, or parent-infant sleeping arrangements in adjusted models, suggesting that it may not be susceptible to the effects of disrupted sleep in the postpartum period. These findings suggest that it is not infant or parent sleep disruption per se, but rather parent nighttime engagement with the infant that is associated with parent sexual activity frequency. Longitudinal investigations are warranted to examine the directional pathways of these links.

Treating postpartum insomnia: a three arm randomised controlled trial of cognitive behavioural therapy and light dark therapy

BACKGROUND

Insomnia symptoms are common during the postpartum period, yet interventions remain scarce. This trial aimed to simultaneously examine the efficacy of cognitive behavioural therapy (CBT) and light dark therapy (LDT), targeting different mechanisms, against treatment-as-usual (TAU), in reducing maternal postpartum insomnia symptoms.

METHODS

This three-arm randomised controlled trial recruited from the general community in Australia. Nulliparous females 4-12 months postpartum with self-reported insomnia symptoms [Insomnia Severity Index (ISI) scores >7] were included; severe medical/psychiatric conditions were excluded. Participants were randomised 1:1:1 to CBT, LDT, or TAU stratified by ISI (< or ⩾14) and infant age (< or ⩾8 months). Participants and principal investigators were unblinded. Six-week interventions were delivered via digital materials and telephone. The primary outcome was insomnia symptoms (ISI), assessed pre-, midpoint-, post- (primary endpoint), and one-month post-intervention. Analyses were intention-to-treat using latent growth models.

RESULTS

114 participants (CBT = 39, LDT = 36, TAU = 39; Mage = 32.20 ± 4.62 years) were randomised. There were significantly greater reductions in ISI scores in CBT and LDT (effect sizes -2.01 and -1.52 respectively, p < 0.001) from baseline to post-intervention compared to TAU; improvements were maintained at follow-up. Similar effects were observed for self-reported sleep disturbance. There were greater reductions in fatigue in CBT (effect size = 0.85, p < 0.001) but not LDT (p = 0.11) compared to TAU. Changes in sleepiness, depression, and anxiety were non-significant compared to TAU (all p > 0.08). Four participants (11%) in the LDT group reported headaches, dizziness, or nausea; no others reported adverse events.

CONCLUSIONS

Therapist-assisted CBT and LDT were feasible during the first postpartum year; data at post-intervention and 1-month follow-up support their safety and efficacy in reducing postpartum insomnia symptoms.

Ecological momentary assessment of postpartum outcomes in mothers of multiples: lower maternal-infant bonding, higher stress, and more disrupted sleep

Research on mental health in mothers of multiples has neglected important outcomes like postpartum bonding and relationship satisfaction and is limited by reliance on single-administration, retrospective measures. This study fills these gaps by assessing previously unexamined variables and using ecological momentary assessment (EMA), wherein participants answer repeated, brief surveys to measure real-world, real-time outcomes. This online study recruited 221 women and compared outcomes in those who birthed multiples (n = 127, 57.47%) vs. singletons (n = 94, 42.53%). When recruited, participants were either 6-12 (n = 129, 58.37%) or 18-24 (n = 83, 37.56%) weeks postpartum. All 221 participants completed baseline measures of self-reported depression, anxiety, stress, sleep, relationship satisfaction, and maternal-infant bonding. One hundred thirty participants (58.82%) engaged in 7 days of EMA assessing self-reported momentary mood, stress, fatigue, bonding, and sleep. Data were analyzed using two-by-two ANOVAs and hierarchical linear modeling. Mothers of multiples reported more baseline parenting stress and less maternal-infant bonding than mothers of singletons (ps < .05). Mothers of multiples who were 6-12 weeks postpartum reported the lowest bonding (p = .03). Mothers of multiples also reported more momentary stress, overwhelm, nighttime awakenings, and wake time after sleep onset (ps < .05). The latter two variables positively correlated with momentary fatigue, stress, and worse mood (ps < .05). Mothers of multiples experienced worse postpartum bonding, more stress, and more interrupted sleep than mothers of singletons. This population may benefit from tailored postpartum interventions to decrease stress, increase bonding, and improve sleep.

Effects of Nonpharmacological Interventions on Sleep Quality and Insomnia in Perimenopausal and Postmenopausal Women: A Meta-Analysis

This study aimed to analyze the effects of nonpharmacological interventions on perimenopausal and postmenopausal women with sleep problems. Eight databases (MEDLINE/PubMed, Cochrane Library, EMBASE, CINAHL, and four Korean databases) were searched, from their inception through to 30 November 2021, for randomized controlled trials (RCTs) evaluating the effects of nonpharmacological interventions versus control conditions on sleep quality and insomnia in perimenopausal and postmenopausal women. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and the severity of insomnia was assessed using the Insomnia Severity Index (ISI). In the meta-analysis, corrected standardized mean differences (SMDs; Hedges' g) and 95% confidence intervals (CIs) were calculated as effect measures by applying the random effects model and inverse variant method. Fifteen trials met our inclusion criteria. Nonpharmacological interventions were found to have positive effects on sleep quality, measured with the PSQI (SMD = -1.32; 95% CI = -1.78 to -0.86; p < 0.001), and on the severity of insomnia, measured using the ISI (SMD = -1.11; 95% CI = -1.82 to -0.41; p = 0.002), compared with the control groups. Among perimenopausal and postmenopausal women with sleep problems, nonpharmacological interventions improved sleep quality and reduced the severity of insomnia.

Effectiveness of Exercise in Improving Sleep Outcomes among Perinatal Women: A Systematic Review and Meta-analysis of randomised Controlled Trials

BACKGROUND

Sleep problems are prevalent among perinatal women, contributing to the poor overall well-being of mother and child. Exercise is an inexpensive and sustainable intervention to improve sleep outcomes and can be personalized accordingly to individuals. This systematic review and meta-analysis aim to consolidate available evidence to evaluate the effectiveness of exercise on improving sleep outcomes among perinatal women.

METHODS

Eight databases (CINAHL, Cochrane, EMBASE, PsycINFO, PubMed, Scopus, Web of Science and ProQuest) were used to perform a systematic search for studies in the English language from the inception of each database to 7 December 2019. The quality of studies was assessed using the risk of bias and GRADE. Review Manager was used for meta-analyses. Heterogeneity was determined by Cochran's Q (chi-square) and I² values. The overall effect was evaluated using effect size and Z-statistics.

RESULTS

A total of 2,139 records were identified. Ten randomized controlled trials were included, with seven in the meta-analysis, involving 998 pregnant and postpartum women across eight countries. With medium to very large effect sizes, the results favored exercise interventions on sleep quality, sleep efficiency, sleep duration, sleep latency, insomnia, diurnal tiredness and daytime dysfunction.

CONCLUSION

Exercise interventions produced significant effects on improving sleep among perinatal women. This can increase advocacy for exercise among perinatal women to improve sleep and general health. Future randomized controlled trial designs should adhere to the Consolidated Standards of Reporting Trials and Template to ensure reliability when conducting and reporting such studies.

Mental health promotion and protection relating to key life events and transitions in adulthood: a rapid systematic review of systematic reviews

BACKGROUND

During the decades representing working-age adulthood, most people will experience one or several significant life events or transitions. These may present a challenge to mental health.

AIM

The primary aim of this rapid systematic review of systematic reviews was to summarise available evidence on the effectiveness of interventions to promote and protect mental health relating to four key life events and transitions: pregnancy and early parenthood, bereavement, unemployment, and housing problems. This review was conducted to inform UK national policy on mental health support.

METHODS

We searched key databases for systematic reviews of interventions for working-age adults (19 to 64 years old) who had experienced or were at risk of experiencing one of four key life events. Titles and abstracts were screened by two reviewers in duplicate, as were full-text manuscripts of relevant records. We assessed the quality of included reviews and extracted data on the characteristics of each literature review. We prioritised high quality, recent systematic reviews for more detailed data extraction and synthesis.

RESULTS

The search and screening of 3997 titles/abstracts and 239 full-text papers resulted in 134 relevant studies, 68 of which were included in a narrative synthesis. Evidence was strongest and of the highest quality for interventions to support women during pregnancy and after childbirth. For example, we found benefits of physical activity and psychological therapy for outcomes relating to mental health after birth. There was high quality evidence of positive effects of online bereavement interventions and psychological interventions on symptoms of grief, post-traumatic stress, and depression. Evidence was inconclusive and of lower quality for a range of other bereavement interventions, unemployment support interventions, and housing interventions.

CONCLUSIONS

Whilst evidence based mental health prevention and promotion is available during pregnancy and early parenthood and for bereavement, it is unclear how best to support adults experiencing job loss, unemployment, and housing problems.

Use of Child Care Attenuates the Link Between Decreased Maternal Sleep and Increased Depressive Symptoms

OBJECTIVE

Sleep disruption is common among postpartum women and is linked with depression. Child care may alleviate parenting stress and protect new mothers against symptoms of depression.

METHODS

Mothers from the NURTURE study, a birth cohort of 666 women of full-term infants, completed questionnaires during home visits when their infants were 3, 6, 9, and 12 months old. The Edinburgh Postnatal Depression Scale and the Perceived Stress Scale were used to measure depressive symptoms and stress, respectively. Mothers reported total nightly sleep duration for themselves and their infants, child care arrangements, marital status, and income. We used mixed-effects models adjusting for income, marital status, and child age to examine the indirect effect of infants' sleep on maternal mental health through mothers' sleep and assessed whether patterns differed depending on child care.

RESULTS

Decreased maternal sleep mediated the association between infant sleep and maternal mental health. When infants slept 1 hour less than usual, mothers slept 7 fewer minutes (B = 0.19, 95% confidence interval [CI], 0.01 to 0.27) and reported more depressive symptoms (B = -0.27, 95% CI, -0.43 to -0.11) and stress (B = -0.33, 95% CI -0.58 to -0.09). Child care moderated the indirect effect; decreased maternal sleep was not associated with increased depressive symptoms (and was not a mediator) when mothers had child care (indirect effect = -0.001, 95% CI, -0.03 to 0.03).

CONCLUSION

Use of infant child care reduced the link between maternal sleep and depressive symptoms. Regular access to child care may be a method to mitigate feelings of depression for new mothers.

Randomized controlled trial of digital cognitive behavior therapy for prenatal insomnia symptoms: Effects on postpartum insomnia and mental health

STUDY OBJECTIVES

To evaluate the effects of digital cognitive behavior therapy for insomnia (dCBT-I) delivered during pregnancy on subjective sleep outcomes, depressive symptoms, and anxiety symptoms through six months postpartum.

METHODS

People up to 28 weeks gestation (N=208) with insomnia were randomized to six weekly sessions of dCBT-I or standard care. We report follow-up data at three and six months postpartum. The primary outcome was insomnia symptom severity. Secondary sleep outcomes included global sleep quality and insomnia caseness. Mental health outcomes included depressive and anxiety symptom severity. We evaluated between-condition differences in change from baseline for each postpartum timepoint and categorical outcomes.

RESULTS

dCBT-I participants did not experience significantly greater improvements in insomnia symptom severity relative to standard care participants, but they did experience higher rates of insomnia remission and lower rates of insomnia caseness at six months postpartum. dCBT-I participants experienced greater improvements in depressive symptom severity from baseline to both postpartum timepoints, and in anxiety symptom severity from baseline to three months postpartum. The proportion of participants with probable major depression at three months postpartum was significantly higher among standard care (18%) than dCBT-I (4%, p=.006) participants; this between-condition difference was pronounced among the subset (n=143) with minimal depressive symptoms at baseline (18% vs 0%).

CONCLUSION

dCBT-I use during pregnancy leads to enduring benefits for postpartum insomnia remission. Findings provide strong preliminary evidence that dCBT-I use during pregnancy may prevent postpartum depression and anxiety, which is notable when considering the high frequency and importance of these problems.

Cognitive Behavioural Therapy and Light Dark Therapy for Maternal Postpartum Insomnia Symptoms: Protocol of a Parallel-Group Randomised Controlled Efficacy Trial

Background: Symptoms of insomnia are common in new mothers and have been associated with a range of negative maternal and child outcomes. Despite this, interventions to improve maternal postpartum sleep remain scarce. Cognitive Behavioural Therapy (CBT) and Light Dark Therapy (LDT) represent two promising interventions for insomnia symptoms and associated daytime consequences such as fatigue. This randomised controlled trial examines whether CBT and LDT improve maternal insomnia symptoms as the primary outcome and maternal sleep disturbance, mood, fatigue, and sleepiness as secondary outcomes. This protocol paper outlines the development, design, and implementation of the trial. Methods: Participants are an Australian community-sample of 90 first-time mothers who are 4-12 months postpartum with self-reported symptoms of insomnia (Insomnia Severity Index scores ≥ 8). Exclusion criteria include current severe sleep/psychiatric disorders, unsettled infant sleep behaviour, sleep-affecting medication use, and photosensitivity. Eligible women are randomised into a CBT (strategies targeting sleep, worries, fatigue, and relaxation), LDT, or a treatment-as-usual control condition. Interventions are therapist-assisted and personalised through two telephone calls and include a series of automated intervention emails delivered over 6 weeks. Primary and secondary outcomes are assessed at four time points: baseline, intervention mid-point, post-intervention, and 1-month post-intervention. Discussion: If found effective, these interventions could represent efficacious, safe, and inexpensive treatments for improving postpartum insomnia and mitigate its negative impact on maternal well-being. Interventions tested are highly scalable and can be integrated into postpartum care and made available to the broader community.

Melatonin use during pregnancy and lactation: A scoping review of human studies

OBJECTIVE

The prevalence of sleep disorders during the perinatal period is high and large health administrative database surveys have shown that the use of exogenous melatonin in pregnant populations is quite common, about 4%. Much of the concern about using melatonin during pregnancy and breastfeeding stems from animal research. Thus, the objective of this article is to provide a critical review of human studies related to exogenous melatonin use during pregnancy and breastfeeding.

METHODS

The electronic databases Ovid, MEDLINE, Embase, and the Cochrane Library were searched using terms and keywords related to melatonin, pregnancy, and breastfeeding.

RESULTS

Fifteen studies were included in this review. Eight focused on melatonin use during pregnancy and seven focused on melatonin use during breastfeeding. There was a variety of study designs, including case reports, cohort studies, and clinical trials. There is a lack of randomized, controlled trials examining the efficacy and safety of melatonin as a treatment for sleep disorders during pregnancy or breastfeeding and, notably, insomnia was not the primary outcome measure in any of the studies included in this review. Clinical trials that used exogenous melatonin during pregnancy and breastfeeding for other clinical conditions have not suggested major safety concerns or adverse events.

CONCLUSION

Contrary to what animal studies have suggested, evidence from clinical studies to date suggests that melatonin use during pregnancy and breastfeeding is probably safe in humans. This review further emphasizes the need for clinical studies on sleep disorders, including exogenous melatonin, during pregnancy and lactation.

Relaxation interventions for improving sleep outcomes in perinatal women: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Sleep problem is common amongst perinatal women, and stress may trigger and intensify sleep problems in a vicious cycle. Relaxation interventions are gradually being adopted to improve sleep quality in various populations, but little is known about their effectiveness in perinatal women.

OBJECTIVE

To evaluate the effects of relaxation interventions on sleep outcomes amongst all perinatal women aged 18 and above, and identify the essential type, regime and approach in designing relaxation intervention.

DESIGN

Systematic review and meta-analysis of 11 studies among 1046 perinatal women.

DATA SOURCES

We searched Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Excerpta Medica dataBASE, PsycINFO, ProQuest Dissertations and Theses, PubMed and Web of Science from their inception until December 15, 2019.

REVIEW METHODS

Studies were assessed for clinical and statistical heterogeneity and considered for meta-analysis. Comprehensive Meta-analysis and The Cochrane Risk of Bias tool were used for meta-analyses and assessing of risk of bias, respectively.

RESULTS

A total of 6346 records were identified, and 11 randomised control trials were selected. Significantly large effects were found in relaxation interventions in improving sleep quality (Cohen's d = 2.55), disturbance (Cohen's d = 1.52), latency (Cohen's d = 1.82) and duration (Cohen's d = 1.14) when compared with those in the control groups. Subgroup analyses showed that antenatal women who performed progressive muscle relaxation (PMR) by themselves for preventive function and long-term practice showed improved sleep quality compared with their counterparts.

CONCLUSION

PMR is preferable as a supplementary intervention to current existing antenatal care. The grade of the overall evidence of the outcomes ranged from very low to low.

IMPLICATIONS FOR PRACTICE

The meta-analysis addressed the effect of relaxation interventions on sleep outcomes amongst perinatal women. Relaxation interventions may effectively improve sleep quality, disturbance, latency and duration amongst perinatal women early in antenatal period. However, further well-designed trials in large samples are required.

Effect of a behavioral-educational sleep intervention for first-time mothers and their infants: pilot of a controlled trial

STUDY OBJECTIVES

This study tested the acceptability and efficacy of a perinatally delivered behavioral-educational sleep intervention.

METHODS

Participants were 40 primiparous women assigned in late pregnancy to either an intervention (n = 20) or control (n = 20) group. The sleep intervention group (SIG) received prenatal anticipatory education and guidance regarding their own and their infant's sleep during the first 3 months postpartum. This was reinforced during phone calls within the first 6 weeks postpartum. The control group (CG) received brief sleep hygiene information at a prenatal session, followed by 2 phone calls during the same period. Mother-infant pairs wore actigraphs for 48 hours at 6 and 12 weeks postpartum, and mothers kept sleep diaries. Questionnaires completed in late pregnancy and 6 and 12 weeks postpartum related to sleep, newborn care, and mood. The main outcome measures included maternal sleep quantity, efficiency, and self-reported quality and infant sleep duration and consolidation.

RESULTS

Mothers reported high acceptability of the study processes. Sleep duration and quality increased for mothers and infants across time in both groups, with a significantly greater increase in nocturnal sleep duration for mothers in the SIG.

CONCLUSIONS

Prenatal sleep guidance and postnatal follow-up seems to enhance nocturnal sleep of mothers, change their perceptions of their own sleep, and increase confidence in managing their infant's sleep. Follow-up at later intervals and replication with larger, more diverse samples may reveal further differences.

A comprehensive model of women's social cognition and responsiveness to infant crying: Integrating personality, emotion, executive function, and sleep

Disparate lines of research suggest that women's (a) emotion regulation and personality, (b) executive function and (c) sleep may be important predictors of mothers' cry responding in part through their effects on social cognition. However, the extent to which each contributes to cry responding independently remains unknown. We examined this question in a convenience sample of 109 nulliparous undergraduate women. Women completed online surveys to assess personality and emotion dysregulation traits, then visited the lab for a testing session during which they reported on sleep the night before and reactions to videotapes of crying infants and completed computerized working memory and inhibitory control tasks under challenging noise conditions (exposure to traffic and cry sounds). Results indicate that women's positive personality and higher working memory were associated with higher levels of infant-oriented cry processing (i.e., accurate distress detection, empathy and situational/emotional attributions about distress), which in turn was associated with higher intended responsiveness to infant crying. Emotion dysregulation and deficits in inhibitory control were associated with higher levels of self-oriented cry processing (i.e., anger, anxiety, negative and emotion minimizing attributions in response to infant distress), which in turn was associated with lower cry responsiveness. Short-term sleep deprivation was associated with lower intended responsiveness via the above path from poorer inhibitory control to heightened self-oriented cry processing. Findings suggest that sleep, emotional and cognitive factors are associated with cry processing and subsequent responsiveness independent of one another.

Sleep Health Promotion Interventions and Their Effectiveness: An Umbrella Review

Sleep is receiving increasing attention in public health. The aim of this umbrella review is to determine what non-pharmacological sleep health interventions have been evaluated among healthy populations, by examining target groups, settings, and effectiveness in improving sleep quality and duration. Comprehensive searches were conducted in five electronic databases (January 1975-February 2019), yielding 6505 records. Thirty-five articles were selected meeting the following eligibility criteria: (1) systematic reviews or meta-analyses of (2) sleep health interventions in (3) primarily healthy populations. Two reviewers independently screened for inclusion, extracted the data, and assessed the review quality. This umbrella review was registered with PROSPERO (CRD42019126291). Eleven intervention types were defined, and their effectiveness discussed. Substantial evidence demonstrated the effectiveness of later school start times, behavior change methods, and mind-body exercise. Other intervention types, including sleep education or relaxation techniques, demonstrated some promising impacts on sleep, but with less consistent evidence. Results were limited by high heterogeneity between studies, mixed results, and variable review quality. Nevertheless, this umbrella review is a first step towards understanding the current state of sleep health promotion and gives an overview of interventions across the lifespan.

The effects of infant behavioural sleep interventions on maternal sleep and mood, and infant sleep: A randomised controlled trial

Infant sleep problems are one of the first challenges for parents, negatively influencing infants and mothers. The present study examined the effects of preventive behavioural sleep intervention (BSI) on infant sleep patterns, maternal sleep quality, and depression. A clinical randomised multicentre controlled trial was conducted involving 82 mothers and their infants aged 2-4 months in Iran from August 2018 to April 2019. The intervention group received BSI, which included one individual 90-min class session, booklet, voice messages, and follow-up calls; while the control group received training on general infant safety. Details of infant sleep, maternal sleep quality, and postnatal depression were measured through the sleep diary, Pittsburgh Sleep Quality Index, and Edinburgh Postnatal Depression Scale, respectively, before and at 8 weeks after the training. In the intervention group, both the mean infant "night-time sleep period" and infant "longest self-regulated sleep period" were 81 min longer than the controls (p < .001). With an improvement of 160 min, the mean infant bedtime was decreased to 22:20 hours in the intervention group, substantially earlier than the controls (00:30 hours). The mean infant "night-time awakenings with signals" did not significantly change (2.6- and 2.5-times in the intervention and control groups, respectively). The intervention led to a significant improvement in maternal sleep quality and depression (p < .05). The present study acknowledges the positive effects of an early preventive infant BSI on infant sleep, maternal mood, and maternal sleep. Our present results also imply the importance of considering sleep patterns differences and cultural-based intervention's design.

Outcomes of a walking exercise intervention in postpartum women with disordered sleep

AIM

Good sleep quality is essential to physical and mental-health-related quality of life. The purpose of this study was to evaluate the effects of a walking exercise in relieving sleep quality, fatigue, and depression in new mothers during the postpartum period.

METHODS

This quasi-experimental study was conducted at a teaching hospital in southern Taiwan. One hundred and four eligible postpartum women with poor sleep quality (Postpartum Sleep Quality Scale; PSQS score ≧16) were assigned to either the experimental group (n = 50) or the control group (n = 54) according to their individual preferences. The participants in the experimental group participated in a 12-week stride walking exercise intervention. The control group did not receive any exercise intervention. The PSQS, Postpartum Fatigue Scale, and Edinburgh Postnatal Depression Scale were used to assess outcomes.

RESULTS

Repeated measures ANOVA demonstrated that the experimental group participants perceived milder physical symptoms associated with sleep inefficiency at 4-week posttest (F = 7.25, p < 0.01) than their control group peers. However, no significant differences were found between two groups in terms of either fatigue or depression at 4-week and 12-week posttest.

CONCLUSION

Significant improvement in the physical symptoms associated with sleep inefficiency was observed. The findings may be used to encourage postpartum women with disordered sleep to incorporate 20-30 min of stride walking into their regular routine to improve sleep quality.

Reconciling relationships with physical activity: a qualitative study of women's postnatal physical activity decision-making

Background

Challenges with engaging in postnatal physical activity can negatively affect the health of women and their families. This study investigated women’s physical activity decision-making processes and strategies to support their physical activity as part of a healthy postpartum transition.

Methods

Thirty healthy women with infants aged 2.5–12 months completed 3-day activity diaries and an individual interview. Using Glaser and Charmaz’s grounded theory methodology, the core category, reconciling relationships with physical activity, was constructed, which explained women’s processes of postnatal physical activity decision-making.

Results

Through reconciling relationships with physical activity, women discerned the types of physical activity they were comfortable pursuing at various points in the postpartum transition. Based on the meaning physical activity held for participants and their views about risks, supports, and resources, women gauged their capacity and the workability of their physical activity desires. Most women were uncertain of their capacity (physical, emotional) to return to physical activity and viewed the achievement of several or all of their desired physical activities as unworkable. Only a small group of women fully pursued the desirable physical activities they viewed as important for their well-being. Women adjusted the strategies they used to achieve physical activity when their expectations of capacity and workability did not align with their experiences. Some women lacked access to resources or supportive messaging about postpartum physical activity and downgraded their physical activity pursuit after negative personal physical or childcare experiences.

Conclusions

Women can benefit from discussions about physiological birth recovery and navigating community and peer resources to support physical activity access and the safe return to physical activity following birth.

Appraisal of systematic reviews on interventions for postpartum depression: systematic review

BACKGROUND

Postpartum depression (PPD) is a highly prevalent mental health problem that affects parental health with implications for child health in infancy, childhood, adolescence and beyond. The primary aim of this study was to critically appraise available systematic reviews describing interventions for PPD. The secondary aim was to evaluate the methodological quality of the included systematic reviews and their conclusions.

METHODS

An electronic database search of MEDLINE, Embase, and the Cochrane Library from 2000 to 2020 was conducted to identify systematic reviews that examined an intervention for PPD. A Measurement Tool to Assess Systematic Reviews was utilized to independently score each included systematic review which was then critically appraised to better define the most effective therapeutic options for PPD.

RESULTS

Of the 842 studies identified, 83 met the a priori criteria for inclusion. Based on the systematic reviews with the highest methodological quality, we found that use of antidepressants and telemedicine were the most effective treatments for PPD. Symptoms of PPD were also improved by traditional herbal medicine and aromatherapy. Current evidence for physical exercise and cognitive behavioural therapy in treating PPD remains equivocal. A significant, but weak relationship between AMSTAR score and journal impact factor was observed (p = 0.03, r = 0.24; 95% CI, 0.02 to 0.43) whilst no relationship was found between the number of total citations (p = 0.27, r = 0.12; 95% CI, - 0.09 to 0.34), or source of funding (p = 0.19).

CONCLUSION

Overall the systematic reviews on interventions for PPD are of low-moderate quality and are not improving over time. Antidepressants and telemedicine were the most effective therapeutic interventions for PPD treatment.

The influence of sleep quality on weight retention in the postpartum period

Poor sleep in the postpartum is often treated as an unavoidable consequence of childbirth. This study aims to compare objective and subjective measures of sleep, explore the relationship between sleep and postpartum weight retention (PPWR), and investigate factors that may contribute to sleep quality in the postpartum period. In this cross-sectional cohort, PPWR, sleep quality (Pittsburgh Sleep Quality Index (PSQI)), and objective sleep and physical activity (accelerometry) were assessed in 109 women 0–52 weeks postpartum. Anthropometric and demographic data were collected. Gestational weight gain (GWG) was classified as inadequate, appropriate, or excessive according to Institute of Medicine guidelines. Average GWG (33.7 lbs) and PPWR (5.39 lbs) were not different between “good” (PSQI < 6) and “bad” (PSQI ≥ 6) sleepers. Following adjustment, mothers with excessive GWG who were “bad” sleepers had 5.26 higher odds of PPWR ≥ 10 lbs compared with all other combinations of GWG and PSQI. PSQI was not correlated with total sleep time (accelerometer-derived). Light activity and moderate-to-vigorous physical activity (MVPA) were associated with reduced odds of being a “bad” sleeper. The influence of GWG on PPWR was modified by postpartum sleep quality. Both light activity and meeting the MVPA guidelines in the postpartum were associated with higher sleep quality.

Novelty Subjectively rated poor sleep may represent the number of awakenings and wake after sleep onset in postpartum women. Poor postpartum sleep quality increases excessive postpartum weight retention in women with excessive GWG. Women doing light-to-vigorous physical activity in the postpartum are less likely to experience poor sleep quality.

Can foot reflexology be a complementary therapy for sleep disturbances? Evidence appraisal through a meta-analysis of randomized controlled trials

AIMS

To systematically summarize and quantify the effects of foot reflexology on improvements in sleep disturbances.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Datasets including PubMed, Web of Science, Scopus, EMBASE, Cochrane Library, Google Scholar, CINAHL and two Chinese electronic databases (i.e., AiritiLibrary and China National Knowledge Infrastructure) were used to search from their inception to 31 January 2019.

REVIEW METHODS

Studies which were randomized controlled trials that reported changes in sleep disturbances after the intervention among adults over 18 years old and written in the English or Chinese language were included. Two reviewers' independently assessed the eligibility, extracted data, and conducted a quality assessment. Based on the extracted data, two separate meta-analyses were performed.

RESULTS

Forty-two articles with a total sample of 3,928 participants were included in the systematic review and were eligible for the meta-analysis. The most commonly employed outcome measurement tool was the Pittsburgh Sleep Quality Index, followed by the therapeutic effect between the intervention and control groups (as evaluated by participants with sleep problems compared with those without sleep problems in each group after the intervention). Results revealed that foot reflexology resulted in a greater reduction in the sleep quality score compared with the controls (Hedges' g = -1.37; 95% confidence interval (CI) = -1.81~-0.94). As for the therapeutic effect, participants in the intervention group were less likely to have sleep problems than those in the control group (pooled odds ratio = 0.25; 95% CI = 0.19 ~ 0.31).

CONCLUSION

The findings suggested that foot reflexology produced significant improvements in sleep disturbances.

IMPACT

Foot reflexology is a non-invasive and convenient intervention and regularly receiving foot reflexology can be considered complementary therapy to improve the sleep quality of adults with sleep disturbances. Furthermore, healthcare providers can actively press the solar plexus and heart zones to alleviate sleep disturbances when performing foot reflexology.

Toward prevention of bipolar disorder in at-risk children: Potential strategies ahead of the data

BACKGROUND

Despite the well-documented negative impact of untreated bipolar illness, approaches to early intervention in childhood-onset bipolar and related disorders are not well delineated.

METHODS

We reviewed the extant treatment literature on children at high risk for bipolar disorder, with definitions based on family history, childhood adversity, and prodromal symptoms.

RESULTS

A panoply of approaches have been described, but most interventions are based on an inadequate database to support their routine implementation. We classify early stage interventions as a function of their safety and tolerability with the hope that these might generate more rigorous study and a stronger database.

LIMITATIONS

Critics may rightly argue that identifying viable treatment methods is premature given our lack of ability to reliably predict illness trajectory in very young children. However, many of the psychosocial and pharmacological interventions we present could have nonspecific positive effects across a variety of symptoms, syndromes, and diagnoses, further enhancing the rationale for more rigorous study.

CONCLUSIONS

Early stage interventions have the potential to improve functioning in prodromal illness and exert long-term positive effects on the course of illness. Many of the safest interventions deserve consideration for implementation and dissemination studies.

A brief sleep focused psychoeducation program for sleep-related outcomes in new mothers: a randomized controlled trial

Study Objectives

Poor sleep is commonly problematic during pregnancy and postpartum and is associated with depression. This trial investigated the efficacy of prenatal brief, group sleep psychoeducation in improving postpartum maternal sleep, and depression.

Methods

A total of 215 healthy expectant first-time mothers were cluster randomized (1:1) to receive either a 2 × 1.5 h psychoeducation intervention and a set of booklets, or a set of booklets only. Participants completed questionnaires during pregnancy (pre-intervention), and 6 weeks and 4 months postpartum. A post hoc subset of questionnaires was collected at 10 months postpartum. The primary hypothesis was the intervention group would have improved postpartum sleep quality, and reduced levels of insomnia symptoms, fatigue, and daytime sleepiness compared to the control group. Secondary outcomes included depression, anxiety, and stress.

Results

Linear mixed model analyses failed to confirm a group by time interaction on primary or secondary outcomes across all time points. There was no effect of the intervention on outcomes at 6 weeks, or 10 months postpartum. A significant time by group interaction was found at 4 months, favoring the intervention for sleep quality (p = 0.03) and insomnia symptoms (p = 0.03), but not fatigue or daytime sleepiness.

Conclusions

Prenatal sleep psychoeducation did not produce a sustained effect on maternal sleep throughout the postpartum period. There was little evidence of benefits on depressive symptoms.

Non-pharmacological interventions for anxiety in burn patients: A systematic review and meta-analysis of randomized controlled trials

AIM

Present review aimed to conduct a comprehensive review of the effectiveness of non-pharmacological interventions (NPIs) on reducing anxiety in adult burn patients.

METHOD

We searched PubMed, Web of Science, Scopus, Cochrane Library, and Google Scholar databases through September 2019 for randomized clinical trials comparing NPIs to a control group. The primary outcomes were general anxiety and pain anxiety. The Cochrane Risk of Bias Tool was used to assess the risk of bias. All data was pooled with Revman 5.3.

RESULTS

20 studies were eligible for quantitative synthesis. Compared to routine care, Music (4 Randomized Clinical Trials (RCTs), Standardized Mean Difference (SMD) = -2.00, 95 % Confidence Interval (CI) = -3.21 to -0.79), massage (4 RCTs, SMD= -1.84, 95 % CI= -2.77 to -0.91), hypnosis (2 RCTs, SMD= -1.06, 95 % CI= -2.90 to 0.78), relaxation (2 RCTs, SMD= -0.77, 95 %CI= -1.52 to -0.02), transcranial direct current stimulation (1 RCT, SMD= -1.92, 95 %CI= -2.54 to -1.30), and therapeutic touch practices (1 RCT, SMD=-0.45 95 %CI= -0.86 to -0.04), were associated with a significant effect on the anxiety of burn patients. Aromatherapy interventions and virtual reality showed no evidence of a reduction in the anxiety. A large amount of heterogeneity exist among trials. Risk of bias varied across studies. Only one study reported on safety issues.

CONCLUSION

Due to weak evidence, we are unable to make strong recommendations in favor of NPIs for burn anxiety. Further well-designed large sample size randomized clinical trials are warranted.

The Role of Circadian Rhythms in Postpartum Sleep and Mood

Women often experience sleep disturbances and worsening sleep quality throughout pregnancy and postpartum. Circadian rhythms are closely linked to sleep problems and mood disorders. This systematic review provides a summary of studies of circadian rhythms and associated sleep problems and maternal distress, among postpartum women. Articles were idenitfied through a systematic literature search. Circadian rhythm disturbances were strongly correlated with depression, social factors and mothers`s exposure to light postpartum. Future research should include larger, prospective studies as well as randomized controlled trials for measuring effect of circadian rhythm interventions on postpartum mental health outcomes.
