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

Effect of bitter orange blossom distillate on anxiety and sleep disorder in mothers with infants admitted to neonatal intensive care unit: A Randomized controlled clinical trial

OBJECTIVE

Mothers of neonates admitted to the intensive care unit are prone to sleep disorders due to stress and anxiety. Some herbs have anti-anxiety and sedative properties. This study aimed to investigate the effect of bitter orange blossom distillate on anxiety and sleep disorders in mothers with infants admitted to the neonatal intensive care unit.

METHODS

This randomized controlled clinical trial was conducted from 2021 May 15 to 2022 February 2, on 60 mothers with NICU-admitted infants in one of the medical teaching centers affiliated with Babol University of Medical Sciences, Iran. Permuted block randomization was used to assign the mothers to the experimental (bitter orange blossom distillate syrup) and control groups (syrup prepared from water and sugar). Given the impossibility of blinding the participants, allocation concealment was used to prevent the researcher from predicting the future allocation of the samples to the groups. In addition, the statistical consultant received coded data pertaining to the type of intervention in each group. A demographic questionnaire, the Spielberger State and Trait Anxiety Inventory (STAI), and the General Sleep Disorder Scale were employed to collect data. We assessed the level of anxiety and sleep disorder (in both groups before the intervention and again after the last day of the intervention). Data were analyzed using SPSS V22 software. A P-value less than 0.05 were considered significant.

RESULTS

The mean and standard deviation of the sleep disorder score in the intervention group from (50.26±5.81) to (44.70±6.94) and in the control group from (50.46±6.95) to (48.53±8.62) changed. The covariance test showed that bitter orange blossom distillate syrup has a significant effect on the improvement of sleep disorders (P = 0.01, Effect size = 0.09), but there was no significant difference in the State and Trait anxiety level of mothers (P = 0.122, 0.144 and Effect size = 0.04, 0.03) respectively.

CONCLUSIONS

Due to the positive effect of bitter orange blossom distillate syrup on sleep disorders of mothers with hospitalized babies, this low-cost and low-risk intervention is recommended.

Maternal Reports of Preterm and Sick Term Infants' Settling, Sleeping and Feeding in the 9 Months after Discharge from Neonatal Nursery: An Observational Study

The effects of preterm birth, neonatal morbidities and environmental influences on infant sleep development is an important yet under-researched topic, with little known about normative sleep for infants born sick or preterm. The aim of this prospective, observational longitudinal study was to evaluate maternal perceptions and degree of bother with infant sleep behaviours and feeding outcomes across the first 9 months after discharge for sick/preterm infants cared for in the neonatal intensive care unit (NICU) and for healthy term-born infants. This paper reports outcomes for the sick/preterm cohort (I = 94) that were recruited from two NICUs in Perth, Western Australia. Total bother scores were on average 20.2% higher at 9 months than at two weeks post-discharge (p < 0.001). Increased night waking frequency, evening settling duration and crying duration were all positively associated with total bother scores. Maternal confidence scores were negatively associated with maternal bother scores; with each unit increase in confidence, maternal bother decreased by 8.5% (p < 0.001). Covariates such as birth gestation, breastfeeding status and multiple births were not associated with maternal bother. Families may benefit from additional support when experiencing increased night waking frequency and crying and settling durations in the first 9 months after discharge from NICU.

Small vulnerable newborns-big potential for impact

Despite major achievements in child survival, the burden of neonatal mortality has remained high and even increased in some countries since 1990. Currently, most neonatal deaths are attributable to being born preterm, small for gestational age (SGA), or with low birthweight (LBW). Besides neonatal mortality, these conditions are associated with stillbirth and multiple morbidities, with short-term and long-term adverse consequences for the newborn, their families, and society, resulting in a major loss of human capital. Prevention of preterm birth, SGA, and LBW is thus critical for global child health and broader societal development. Progress has, however, been slow, largely because of the global community's failure to agree on the definition and magnitude of newborn vulnerability and best ways to address it, to frame the problem attractively, and to build a broad coalition of actors and a suitable governance structure to implement a change. We propose a new definition and a conceptual framework, bringing preterm birth, SGA, and LBW together under a broader umbrella term of the small vulnerable newborn (SVN). Adoption of the framework and the unified definition can facilitate improved problem definition and improved programming for SVN prevention. Interventions aiming at SVN prevention would result in a healthier start for live-born infants, while also reducing the number of stillbirths, improving maternal health, and contributing to a positive economic and social development in the society.

Exploring Perceived Stress in Mothers with Singleton and Multiple Preterm Infants: A Cross-Sectional Study in Taiwan

Objective: The aim of this study was to explore mothers’ perceived level of stress one month after hospital discharge following the birth of singleton and multiple preterm infants. Design: A cross-sectional design was used to compare mother’s perceived stress in two groups of postpartum mothers and the relationship of the theoretical antecedents and these variables. Setting: A neonatal intensive care unit in a medical center in Taiwan. Participants: Mothers of 52 singletons and 38 multiple premature infants were recruited. One month after the infant was discharged, the participants completed a self-reported questionnaire that included demographic data about the mother and infant, the 21-item Social Support Scale, and the 15-item Perceived Stress Scale. This was returned by email or completed at the outpatient unit. Analysis: Descriptive and inferential analysis. Results: The mean social support scores were 76.6 and 76.5 (out of 105) for mothers with singleton and multiple birth infants, respectively. The most important supporter was the husband. The mean perceived stress scores of 25.8 and 31.0 for mothers with singleton and multiple birth infants, respectively, were significantly different (p = 0.02). Sleep deprivation and social support were predictive indicators of perceived stress in mothers with preterm infants. Conclusions: We suggest that the differences in stress and needs of mothers with singleton and multiple births should be recognized and addressed in clinics. The findings of this study serve as a reference for promoting better preterm infant care.

Sleep patterns and psychosocial health of parents of preterm and full-born infants: a prospective, comparative, longitudinal feasibility study

Background

The early birth and hospitalization of a preterm infant in neonatal intensive care unit can produce several emotional and behavioural responses including sleep problems for parents. Few studies have explored sleep and its associations with health and HRQoL over time in this vulnerable parent population. This purpose of this study was to evaluate the feasibility of a prospective, comparative, longitudinal study of the sleep patterns and psychosocial health of preterm and full-born infants’ parents during the first postpartum year.

Methods

A prospective, comparative, longitudinal feasibility study was conducted. Parents of preterm infants were compared to parents of full-born infants to identify if there were differences in outcomes between the groups. The parents were instructed to wear actigraphs and complete sleep diaries for two consecutive weeks, and responded to a digital questionnaire covering stress, insomnia, fatigue, depression, social support, self-efficacy, and health-related quality of life. Survey data were collected at infant ages of 2, 6, and 12 months, actigraphy and sleep diary data were collected at infant age of 2 months only. Descriptive analysis was used to describe recruitment and attrition rates. Differences between completers and dropouts were analysed with a chi-square test (categorical data) and Mann–Whitney–Wilcoxon test for two independent samples (continuous variables).

Results

Between June 2019 and March 2020, 25 parents of a preterm infant and 78 parents of a full-born infant were recruited from four neonatal intensive care units and two maternity wards, respectively, in four Norwegian hospitals. Feasibility was predefined as recruiting ≥ 75 parents each of preterm and full-born infants. The target for the full-born group was reached. However, the preterm group recruitment was challenging. Actigraphs, sleep diaries, and questionnaires were evaluated as feasible for use in a future study. Attrition rates were high in both groups at 6 and 12 months. No parent-related characteristics were associated with participation at 6 months. At 12 months, dropouts had a statistically significantly lower age in the full-born group (both parents) and higher age and body mass index in the preterm group (fathers).

Conclusions

A longitudinal study is feasible; however, procedural changes, including using active methods and contacting participants, are necessary to increase the recruitment of preterm infants’ parents.

Application of a Risk Management Framework to Parent Sleep During Skin-to-Skin Care in the NICU

As NICU staff work to increase the frequency, duration, and comfort of skin-to-skin care (SSC) sessions, barriers to implementation are frequently encountered. Safety concerns are often raised when parents fall asleep during SSC intentionally or unintentionally. We present a risk management framework that we use in clinical practice to address risk related to parent sleep during SSC. Our approach is based on the steps of the Risk Management Life Cycle, which include the following: establish context, identify risk, analyze risk, respond to risk, and monitor and adapt response to risk. Clinicians may use this framework in clinical practice to manage risks related to prolonged SSC, specifically when parents relax and fall asleep during SSC.

Effect of Kangaroo Mother Care on the Psychological Stress Response and Sleep Quality of Mothers With Premature Infants in the Neonatal Intensive Care Unit

OBJECTIVE

To investigate the effect of kangaroo mother care on the psychological stress response and sleep quality of mothers with premature infants admitted to the neonatal intensive care unit (NICU).

METHODS

A randomized controlled design was used to recruit participants. The study recruited 126 mothers of premature infants in the NICU from January 2019 to January 2020. The participants were divided into the experimental and control groups according to the random number table method (63 mothers per group). The control group was managed with conventional premature infant treatment, nursing programme, and discharge education, whereas the experimental group was managed with a 4-week kangaroo mother care intervention. The psychological stress state and sleep status of mothers with preterm infants in both the groups were evaluated using the Symptom Check List 90 (SCL-90) and Assens Insomnia Scale (AIS).

RESULTS

After the intervention, the total SCL-90 score and factor scores such as coercion, interpersonal relationships, depression, anxiety, hostility and additional factors, were lower in the experimental group than those in the control group (P < 0.05). The total AIS score and the items such as night waking, total sleep time, total sleep quality, daytime mood and daytime body function were lower in the experimental group than those in the control group (P < 0.05).

CONCLUSIONS

The Kangaroo mother care approach can relieve adverse psychological stress and improve the sleep status of mothers of NICU premature infants after mother-infant separation. It can be promoted and used in mothers of premature infants in the NICU to enhance physical and mental health.

Webcam use in German neonatological intensive care units: an interview study on parental expectations and experiences

BACKGROUND

To bridge the physical distance between parents and children during a neonatal intensive care unit (NICU) stay, webcams are used in few German NICUs. They allow parents to view their infant even when they cannot be present on the ward. The aim of the study was to explore the factors for and against webcam use that parents with or without webcam use encountered.

METHODS

Guideline-based, semi-structured qualitative interviews were conducted in the period from September 2019 to August 2020. Interview transcripts were analysed using a category-based content analysis. The categories were generated in a combined deductive-inductive procedure.

RESULTS

We interviewed 33 mothers and seven fathers. Parents with webcam experience emphasised positive aspects concerning their webcam use. Factors that increased webcam acceptance included feeling certain about the child's well-being and an increased sense of proximity. Only a few critical voices emerged from parents who had webcam experience, e.g. regarding privacy concerns. Parents who had no experience with webcam use showed ambivalence. On the one hand, they expressed a positive attitude towards the webcam system and acknowledged that webcam use could result in feelings of control. On the other hand, reservations emerged concerning an increase of mental stress or a negative influence on parental visitation behaviour.

CONCLUSION

In addition to the parents' positive experiences with webcam use, results show a need within parents who lacked webcam experience. Despite some criticism, it was evident that webcam use was primarily seen as an opportunity to counteract the negative consequences of separation in the postnatal phase.

The Impact of Maternal Symptoms of Perinatal Insomnia on Social-emotional Child Development: A Population-based, 2-year Follow-up Study

Background: Poor sleep quality is a common problem in pregnant women, however there is scarce research evidence regarding the association between maternal perinatal insomnia and later social-emotional child development.Participants: This study is part of the Akershus Birth Cohort, a longitudinal population-based study. Birth record and questionnaire data of 1,346 women were used.Methods: Maternal symptoms of insomnia were measured at pregnancy week 32 and at eight weeks postpartum and social-emotional child development was assessed at two years of child age. Correlational and multiple linear regression analyzes were performed.Results: Both, pre- and postnatal symptoms of insomnia were significantly correlated with poorer social-emotional child development two years later (r = 0.09, p < .01 and r = 0.13, p < .001). Adjusting for potential confounding factors, the prospective effect of maternal symptoms of perinatal insomnia on social-emotional child development remained significant in the multiple linear regression analyzes (β = 0.08, p < .01 and β = 0. 10, p < .01).Conclusions: We found a prospective effect of maternal symptoms of perinatal insomnia on social-emotional child development, highlighting the potential relevance of both pre- and postnatal maternal sleep for later social-emotional child development. Future studies ought to examine the bio-psycho-social mechanisms and implications of poor maternal sleep in the perinatal time in more detail.

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.

Parents' Experiences With a Model of Integrated Maternity and Neonatal Care Designed to Empower Parents

OBJECTIVE

To explore the experiences of parents with an integrated maternity and neonatal ward designed to empower parents by providing family-integrated care (FICare) to mother-newborn couplets in single-family rooms.

DESIGN

A qualitative analysis with a contextual constructivist approach.

SETTING

An integrated maternity and neonatal level 2 ward designed to empower parents in a teaching hospital in Amsterdam, the Netherlands. Maternity and neonatal care, up to and including highly complex care, is provided to mother-newborn couplets in single-family rooms according to the principles of FICare.

PARTICIPANTS

Twenty-seven mothers and nine fathers of newborns who were hospitalized for at least 7 days.

METHODS

We held four focus group discussions and eight semistructured interviews 1 to 3 months after discharge of the newborn to explore which experiences (mechanisms) facilitated or impeded aspects of parent empowerment (outcomes) under which specific conditions of the integrated infrastructure (contexts). We used the realist evaluation model to analyze the data.

RESULTS

Our analysis revealed five themes of parent empowerment (outcomes): Feeling Respected, Gaining Self-Management Tools, Insights Into the Newborn's Condition, Perceived Control, and Self-Efficacy. For each theme, participants reported facilitating and impeding experiences (mechanisms) that were initiated and influenced by the combination of single-family rooms, couplet care, rooming-in, and FICare (contexts). Unrestricted physical proximity to their newborns, 24 hours per day, in a safe private environment offered parents intensive learning experiences through active participation in care. It helped them to achieve independent parenthood at the time of discharge, but it also generated challenges such as power conflicts with the staff; prioritizing care for themselves, siblings, or the newborn; feelings of isolation; and lack of sleep.

CONCLUSION

Providing FICare to mother-newborn couplets in single-family rooms offers parents an intensive learning context for independent parenthood at the time of discharge. Health care professionals should be aware of the challenges and facilitators experienced by parents in the context of close physical proximity to their newborns 24 hours per day in single-family rooms. This awareness will allow them to better support parents in their empowerment process toward independent parenthood at the time of discharge.

A comparative study of mothers of infants hospitalized in an open ward neonatal intensive care unit and a combined pod and single-family room design

Background

The well-being of mothers of infants requiring Neonatal Intensive Care Unit (NICU) hospitalization may be affected by the architectural design of the unit. A few recent studies suggest there may be some drawbacks of single-family rooms (SFRs) for infants and their mothers, such as isolation of mothers and reduced exposure to auditory stimulation for infants.

Purpose

To compare NICU-stress, symptoms of depression, perceptions of nurse-parent support and family-centered care, sleep disturbances, breastfeeding self-efficacy and readiness for discharge in mothers of infants cared for in an open ward (OW) to those cared for in a unit that includes both pods and SFRs.

Methods

A pre-post quasi-experimental study was conducted in a Canadian level 3 unit before and after transitioning to a new unit of 6-bed pods and SFRs. OW data were collected in 2014 and pod/SFR data 1 year after the transition in 2017 to 2018. Mothers of infants hospitalized for at least 2 weeks completed questionnaires about stress, depressive symptoms, support, family-centered care, and sleep disturbances. In the week prior to discharge, they responded to breastfeeding self-efficacy and readiness for discharge questionnaires. They described their presence in the NICU at enrollment and again prior to discharge.

Results

Pod/SFR mothers reported significantly less NICU-stress compared to OW mothers. OW mothers had greater sights and sounds stress and felt more restricted in their parental role. Pod/SFR mothers reported greater respect from staff. Controlling for maternal education, pod/SFR mothers perceived their infant’s readiness for discharge to be greater than OW mothers. There were no significant differences between groups in depressive symptoms, nurse-parent support, sleep disturbances, and breastfeeding self-efficacy.

At enrollment and again in the weeks preceding discharge, pod/SFR mothers were present significantly more hours per week than OW mothers, controlling for maternal education.

Conclusions

Further study of small pods is indicated as these units may be less stressful for parents, and enhance family-centered care, as well as maternal presence, compared to OWs.
