Guided imagery: an innovative approach to improving maternal sleep quality

A Feasibility Study to Assess Sleep and Subsequent Breast Milk Volume Among Mothers With Hospitalized Preterm Infants

BACKGROUND

Sleep is essential for optimal health, and disturbed postpartum sleep is associated with compromised infant attachment. The postpartum experience of mothers with preterm infants is unlike the biological norm, as they are separated from their infants and often express breast milk.

PURPOSE

The purpose of this study was to examine the feasibility of conducting a clinical research study among women with hospitalized preterm infants. We also explored for associations between maternal sleep patterns and sleep-related psychological states and subsequent breast milk volume.

METHODS

Participants were recruited from Magee-Womens Hospital, located in Pittsburgh, Pennsylvania New mothers completed daily sleep and pumping logs and scales to measure stress, trauma, depression, fatigue, and sleep quality.

RESULTS

A total of 78 women were screened, 18 women consented, and a total of 8 participants completed the study. Screening from the postpartum unit increased recruitment. The participants experience worsening sleep quality over time, moderate stress, and fatigue. Stress, postnatal depression, and fatigue are negatively associated with milk volume.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Postpartum recruitment with frequent follow-ups improved recruitment and retention. We present a preliminary association between maternal stress, fatigue, and depression, and subsequent breast milk volume. Sleep-related psychological states may negatively influence milk volume.

Factors Influencing Mothers' Quality of Sleep during Their Infants' NICU Hospitalization

STUDY OBJECTIVES

The purpose of this study is to identify factors associated with Neonatal Intensive Care Unit (NICU) mothers' quality of sleep as measured with the General Sleep Disturbance Scale (GSDS).

METHODS

Recruitment took place in a level 3 NICU. At enrollment, mothers completed a socio-demographic questionnaire, described their presence in the unit and their breast milk expression behavior. They also completed online or paper questionnaires about NICU-related stress, symptoms of postpartum depression, family-centered care, perception of noise and light in the unit, and sleep disturbances. Data regarding the infant's clinical condition were collected from their medical file. Pearson correlations were performed to identify associations between mothers' quality of sleep and other study variables. Subsequently, to compare mothers with a clinically significant GSDS score to mothers with a non-significant score, a binary logistic regression model was conducted.

RESULTS

132 mothers participated. Sleep disturbances of mothers with an infant hospitalized in the NICU was positively correlated with stress (r = 0.40; p = .00), depressive symptoms (r = 0.51; p = .00), and breast milk expression (r = 0.23; p = .01). In addition, for mothers with significant levels of depressive symptoms (OR = 1.19; p = .00), with greater presence in the unit (OR = 1.36; p = .04), or with other children at home (OR = 3.12; p = .04), the likelihood of clinically significant sleep disturbances was increased.

CONCLUSIONS

These results improve our understanding of the factors influencing the quality of sleep of mothers whose premature infant is hospitalized for 2 weeks or more in the NICU. In addition, these results allow the identification of mothers having a higher possibility for sleep disturbance, which enables the implementation of targeted interventions to promote adequate sleep.

Nurses’ strategies to provide emotional and practical support to the mothers of preterm infants in the neonatal intensive care unit: A systematic review and meta-analysis

Aim:

To synthesize and integrate current international knowledge regarding nursing strategies for the provision of emotional and practical support to the mothers of preterm infants in the neonatal intensive care unit.

Methods:

A systematic review and meta-analysis was undertaken. Four English-language databases including EMBASE, PubMed (including MEDLINE), Scopus, and Web of Science were searched from January 2010 to October 2021. Original quantitative studies that were written in English and focused on nursing strategies for the provision of emotional and practical support to the mothers of preterm infants in the neonatal intensive care unit were included. Eligibility assessment, data extraction, and methodological quality appraisal were conducted independently by the review authors. A narrative synthesis of the review results and a meta-analysis were performed.

Results:

Twenty studies that were published from 2010 to 2021 were included in the review. Three categories concerning the review aims were identified: ‘nursing strategies related to mothers’ emotions and infant-mother attachment’, ‘nursing strategies related to mothers’ empowerment’, and ‘nursing strategies related to mothers’ participation in care process and support’. Eight interventional studies that reported mothers’ stress as the study outcome were entered into the meta-analysis. Interventions consisted of the educational programme, spiritual care, telenursing, parent support programme, skin-to-skin care, and guided family centred care. Significantly lower maternal stress was found in the intervention group compared with that of the control group (g: −1.06; 95% confidence interval: −1.64, −0.49; Z = 3.62, p < 0.001).

Conclusion:

This review identified and highlighted key nursing strategies used to provide emotional and practical support to the mothers of preterm infants in the neonatal intensive care unit. They included family centred care, skin-to-skin care, parent support and education programmes, interpersonal psychotherapy, spiritual care, newborn individualized developmental care and assessment programme, and telenursing.

Giving parents support: a randomized trial of peer support for parents after NICU discharge

BACKGROUND

Peer support during inpatient hospitalization has been recommended for NICU parents and can improve maternal mental health. Less is known about the impact of peer support after NICU discharge on parental mental health and infant healthcare utilization.

METHODS

Three hundred families of infants approaching discharge from a Level IV NICU were randomized to receive a care notebook (control) or care notebook plus peer support for 12 months (intervention). Participants reported on measures of stress, depression, anxiety, self-efficacy, and infant healthcare utilization. Analysis compared outcomes between control and treatment groups.

RESULTS

Parental depression, anxiety, stress, and self-efficacy improved significantly for all participants, yet there were no differences between control and intervention groups. Infant ED visits, hospitalizations, immunization status, and developmental status at 12 months did not differ between groups.

CONCLUSIONS

Peer support after NICU discharge did not improve self-reported parental mental health measures or infant healthcare utilization.

Sleep patterns, problems, and ecology in young children born preterm and full-term and their mothers

BACKGROUND

Previous studies of sleep patterns and problems in preterm infants compared to full-term infants have yielded mixed results, with little known about sleep ecology. The aims of this study were to compare sleep patterns, sleep problems, and sleep ecology across developmental stages (birth to 36 months) in preterm (3 or more weeks early) infants and toddlers to those born full-term, in addition to their mothers' sleep.

METHODS

Mothers of 834 young children in Brazil (ages 0-35.9 months), half preterm and half full-term (matched for sex and chronological age), completed the Brief Infant Sleep Questionnaire and the Pittsburgh Sleep Quality Index.

RESULTS

Across the entire sample, preterm and full-term infants were similar for most sleep parameters, including sleep onset latency, number and duration of night awakenings, and sleep duration, as well as sleep ecology parameters, including falling asleep independently and sleep location. However, preterm infants were more likely to be held to initiate sleep, given a bottle to resume sleep after waking, and less likely to be breastfed to resume sleep after waking. Mothers of preterm infants, however, were more likely to report a parent-perceived sleep problem, although maternal-perceived confidence in managing child sleep and bedtime difficulty were similar. Finally, maternal sleep parameters were similar between groups.

CONCLUSIONS

Overall, these results indicate that sleep patterns, sleep problems, and sleep ecology among preterm infants and toddlers and their mothers are largely similar to those of full-term infants and toddlers and their mothers, even within the first few months.

Interventions for sleep problems during pregnancy: A systematic review

Sleep problems during pregnancy are prevalent and could be linked to negative outcomes during pregnancy or post-partum. However, these complaints are often underdiagnosed and undertreated. This review aimed to systematically assess the effectiveness of different interventions to ameliorate poor sleep quality and insomnia during pregnancy. Pubmed, PsycINFO and Medline databases were systematically searched without publication period restriction until 3rd May 2019. Eligible studies had to: include pregnant women of any age and gestational age; use clinical intervention designs targeted at improving sleep outcome; report pre- and post-treatment data for one or more sleep-related outcomes; be published in English, Italian, German, Spanish, or French. Sixteen studies were selected including 1252 expecting mothers. Studies evaluated the efficacy of various interventions: cognitive behavioral interventions for insomnia (4); pharmacotherapy (1); acupuncture (1); mindfulness and yoga (3); relaxation (5) and herbal medication (2). Only six were randomized controlled trials, and only four evaluated longitudinal outcomes. Preliminary support was found for all interventions, but our knowledge is still too limited by lack of evidence. There is an utmost urgency to perform high-quality randomized controlled trials for insomnia interventions during pregnancy and to implement effective programs in standard gynecological care.

Randomized controlled trial investigating the effects of a breastfeeding relaxation intervention on maternal psychological state, breast milk outcomes, and infant behavior and growth

BACKGROUND

Biological signaling and communication between mothers and infants during breastfeeding may shape infant behavior and feeding. This signaling is complex and little explored in humans, although it is potentially relevant for initiatives to improve breastfeeding rates.

OBJECTIVES

The aim of this study was to investigate physiological and psychological aspects of mother-infant signaling during breastfeeding experimentally, testing the effects of a relaxation intervention on maternal psychological state, breast milk intake, milk cortisol levels, and infant behavior and growth.

METHODS

Primiparous breastfeeding mothers and full-term infants were randomly assigned to receive relaxation therapy [intervention relaxation group; n = 33 (RG)] or to the control group [n = 31 (CG); no relaxation therapy] at 2 wk postpartum. Both groups received standard breastfeeding support. Home visits were conducted at 2 (HV1), 6 (HV2), 12 (HV3) and 14 (HV4) wk to measure maternal stress and anxiety, breast milk intake and milk cortisol, and infant behavior and growth.

RESULTS

RG mothers had lower stress scores postintervention than the CG (HV3 ∆ = -3.13; 95% CI: -5.9, -0.3) and lower hindmilk cortisol at HV1 (∆ = -44.5%; 95% CI: -76.1%, -12.9%) but not at HV2. RG infants had longer sleep duration (∆ = 82 min/d; 95% CI: 16, 149 min/d) at HV2 and higher gains in weight and body mass index standardized deviation score than the CG infants (∆ = 0.76; 95% CI: 0.3, 1.22; and ∆ = 0.59; 95% CI: 0.09, 1.1, respectively). RG infants had a mean milk intake at HV3 that was 227 g/d higher than that of the CG infants (P = 0.031) after controlling for gender and milk intake at HV1.

CONCLUSIONS

The trial shows the effectiveness of a simple relaxation intervention for improving maternal and infant outcomes and identifies some potential signaling mechanisms for investigation in future and larger studies, especially in settings where mothers are more stressed, such as those with preterm or low birth weight infants. This trial was registered at clinicaltrials.gov as NCT01971216.

Sleep in parents of preterm infants: A systematic review

BACKGROUND

Sleep disruption during the first postpartum year is associated with several negative health outcomes including postpartum depression. Such disruption may be a greater issue for parents of preterm neonates, yet literature on this subject has not been critically reviewed.

OBJECTIVE

To synthesize literature on sleep quantity, sleep quality, and factors influencing sleep among parents of preterm infants during infant hospitalization and following discharge.

DESIGN

A systematic review.

DATA SOURCES

Medline, EMBASE, CINAHL, PsycINFO, Scopus, and Cochrane Database of Systematic Reviews were searched from their inception to February 2017.

METHODS

Potentially eligible citations were reviewed by two independent reviewers. Both quantitative and qualitative studies were eligible for inclusion. Data on eligible studies and review outcomes were extracted using a customized form.

FINDINGS

Eighteen reports from 16 studies met inclusion criteria. Four studies included a control group of parents of full-term infants. Three studies reported sleep quantity means, of which only one provided values for an exclusive sample of mothers of preterm infants and found on average, mothers obtained 6.3 h of sleep/day in the first 5-10 days. Twelve studies reported on sleep quality; most (n = 10) relied on self-reported measures and identified poor subjective sleep quality whereas two studies objectively measured sleep of poor quality. Parental stress was the most consistent factor associated with sleep quality.

CONCLUSION AND IMPLICATIONS

Quality and quantity of sleep among parents of preterm infants is inadequate and may negatively influence family health outcomes. Further research on correlates and changes in sleep is required to identify at-risk parents and inform targeted clinical recommendations and interventions aimed at maximizing sleep for parents of preterm infants.

Sleep and its relationship to health in parents of preterm infants: a scoping review

BACKGROUND

Sleep is essential for human health and functioning. Parents of preterm infants are susceptible to sleep disturbances because of stress related to the preterm birth. Poor sleep has the potential to affect parental health and well-being. The aim of this study was to identify and map evidence on sleep and its relationship to health in parents of preterm infants. No review has summarized the evidence on this topic.

METHODS

A scoping review was conducted. Seven health and medical electronic research databases were searched for relevant quantitative and qualitative primary studies, including grey literature. The search was performed March 2-7, 2017.

RESULTS

Ten American studies and one Australian study were included in the review. Most research was quantitative and focused on maternal sleep and mental health within the first two weeks after the childbirth. Both objective and subjective sleep measures were used to study sleep at the hospital; actigraphs were not used after discharge. Maternal sleep was poor early postpartum, and this was associated with negative health outcomes. Two cohort studies compared sleep in mothers of preterm and term infants, but the results were conflicting. In one qualitative study, fathers described their inability to catch up on sleep after homecoming with a preterm baby.

CONCLUSIONS

Quantitative studies reporting on maternal sleep early postpartum was most frequently occurring in the results. Qualitative research on the topic was identified as a knowledge gap. More cultural and geographical breadth, including research on fathers' sleep, is recommended in future research.

An Integrative Review of the Sleep Experiences of Mothers of Hospitalized Preterm Infants

OBJECTIVE

To determine what is known about the sleep experiences of mothers of hospitalized preterm infants.

DATA SOURCES

A literature search of PubMed and CINAHL was performed in February 2018. Additional articles were identified from reference lists.

STUDY SELECTION

Whittemore's integrative review methodology was used to synthesize existing literature; 17 articles met eligibility criteria.

DATA EXTRACTION

Data were reported in tabular format, including subjects, purpose, setting, interventions, sleep measurements, psychometric instruments, analyses, and results.

DATA SYNTHESIS

Overall, sleep is disrupted and of poor quality, and many mothers report insomnia with less total sleep time. Potential beneficial interventions include bright light therapy, relaxation guided imagery, and progressive muscle relaxation.

CONCLUSION

Although some interventions show promise, there are significant limitations. Future research should consider maternal/infant separation and milk expression.

Improving Sleep for Hospitalized Antepartum Patients: A Non-Randomized Controlled Pilot Study

STUDY OBJECTIVES

To evaluate feasibility and efficacy of a hospital-based protocol for improving sleep in high- risk antepartum patients.

METHODS

Sleep measures were compared during 1 week of hospitalization before and after implementing a Sleep Improvement Protocol for Antepartum Patients (SIP-AP). A non-randomized convenience sample of usual care controls was compared to a subsequent intervention sample after the protocol was implemented. Women were eligible if they spoke English, were medically stable, pregnant for at least 20 weeks, and hospitalized at least 24 hours; 25 pregnant women had sufficient data for analyses (11 controls, 14 intervention). Sleep was assessed in 3 ways: the Pittsburgh Sleep Quality Index was completed after obtaining consent to estimate sleep quality prior to hospital admission; sleep diary completed each hospital day; and General Sleep Disturbance Scale completed at 7 days or prior to hospital discharge. Symptoms that could affect sleep were assessed with the Memorial Symptom Assessment Scale.

RESULTS

Both groups recorded similar sleep duration (7 hours) but the intervention group had fewer symptoms and significantly (P = .015) lower sleep disturbance scores (53.1 ± 14.5) than controls (71.9 ± 18.8). Participant feedback about the intervention was positive, although adherence to components of the intervention protocol was variable.

CONCLUSIONS

This pilot study provides evidence of the feasibility and preliminary efficacy of the SIP-AP intervention for reducing symptoms and improving sleep of antepartum patients during hospitalization. Further detailed evaluation of specific components of this protocol is warranted, and other types of hospitalized patients may benefit from unit-based modifications to this SIP-AP protocol.

Impact of social isolation on behavioral health in elderly: Systematic review

AIM: To examine and compare the effects of subjective and objective social isolation on behavioral health in elderly adults.

METHODS: A systematic search of PubMed was performed for original research articles from peer-reviewed journals examining one of the following topics: “Social isolation and sleep disturbance”, “social isolation and depression”, or “social isolation and fatigue in older adults”. Studies were selected following the criteria established based on the aim of this review. Data were extracted from the articles by two independent reviewers. Due to the heterogeneity in study designs and outcome measures of the included studies, qualitative and narrative analyses were conducted.

RESULTS: The set criteria were used to select a total of 16 studies for the review. Of the 16, 13 were cross-sectional studies. The characteristics of study populations were identified as follows. A total of 12 studies randomly selected subjects irrespective of pre-existing health conditions. Consequently, an unspecified number of the study subjects had chronic diseases in the studies compared. In addition, cultural and ethnic backgrounds of studies in this review were diverse, and included subjects living in North America, South America, Asia, Europe, and Oceania. Both subjective and objective types of social isolation increased behavioral symptoms, such as sleep disturbance, depressive symptoms, and fatigue in older adults. Furthermore, a few recent studies reported stronger effects of subjective social isolation than objective social isolation on sleep disturbance and depressive symptoms.

CONCLUSION: Social isolation affects behavioral health in older adults. Compared to the objective social isolation, subjective social isolation contributes more significantly to sleep disturbance and depression.

Perceptions of guided imagery for stress management in pregnant African American women

Maternal stress during pregnancy has been associated with numerous adverse pregnancy, birth, and health outcomes. Pregnant African American women have been reported to have higher levels of stress compared to other ethnic or racial groups underscoring the need for effective interventions to reduce stress in this population. The purpose of this study was to gain an in-depth understanding of the perceptions of guided imagery (GI) as a technique for stress management in a cohort of pregnant African American women who participated in a GI intervention as part of a larger mixed methods randomized controlled trial. The 12week intervention was a professionally recorded compact disc with four tracks developed and sequenced to reduce stress and associated symptoms. The findings from this descriptive phenomenologic study were derived from daily logs and interviews from 36 participants randomized to the GI group. Participants described the stressful nature of their lives. Results demonstrated pregnant African American women perceived the intervention as beneficial in reducing stress and the associated symptoms. The emergent themes suggested the intervention offered a respite from their stressful lives, reduced the negative emotional responses to stress and enhanced well-being, benefited other areas of their daily life, and provided an opportunity to connect with their baby. The study results support the perceived efficacy of GI as a stress coping intervention. GI is an economic as well as easy to implement, access and use technique that has potential stress coping benefits as perceived by pregnant African American women.
