Sleep in parents of preterm infants: A systematic review

The effect of perceived social support on fatigue in mothers having twin infants: the mediating role of sleep quality

The aim of this study is to investigate the mediating role of sleep quality in the relationship between multidimensional perceived social support and fatigue among mothers of twin infants. One hundred and six (106) twin mothers participated in this cross-sectional study, who completed the Descriptive Information Form, Multidimensional Scale of Perceived Social Support, Pittsburgh Sleep Quality Index, and Checklist Individual Strength. The scale score averages of the mothers in the study are as follows: social support, 61.41 ± 23.86; fatigue, 77.64 ± 28.68; and sleep quality, 8.26 ± 2.38. According to the path model, perceived social support has a negative effect on poor sleep quality (p = .001, Beta = -0.411), and poor sleep quality has a positive effect on fatigue (p = .001, Beta = 0.335). Sleep quality also mediates the effect of multidimensional perceived social support on mothers' fatigue levels (p = .001, Beta = -0.138). The study results suggest that the perceived social support and fatigue levels of twin mothers are moderate, while their sleep quality is poor. Therefore, mothers of twin infants may benefit from increased social support to alleviate fatigue and enhance sleep quality.

Combining developmental and sleep health measures for autism spectrum disorder screening: an ECHO study

BACKGROUND

Sleep problems are reported for up to 80% of autistic individuals. We examined whether parsimonious sets of items derived from the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) and the Brief Infant Sleep Questionnaire (BISQ) are superior to the standard M-CHAT-R in predicting subsequent autism spectrum disorder (ASD) diagnoses.

METHODS

Participants from 11 Environmental influences on Child Health Outcomes (ECHO) cohorts were included. We performed logistic LASSO regression models with 10-fold cross-validation to identify whether a combination of items derived from the M-CHAT-R and BISQ are superior to the standard M-CHAT-R in predicting ASD diagnoses.

RESULTS

The final sample comprised 1552 children. The standard M-CHAT-R had a sensitivity of 44% (95% CI: 34, 55), specificity of 92% (95% CI: 91, 94), and AUROC of 0.726 (95% CI: 0.663, 0.790). A higher proportion of children with ASD had difficulty falling asleep or resisted bedtime during infancy/toddlerhood. However, LASSO models revealed parental reports of sleep problems did not improve the accuracy of the M-CHAT-R in predicting ASD diagnosis.

CONCLUSION

While children with ASD had higher rates of sleep problems during infancy/toddlerhood, there was no improvement in ASD developmental screening through the incorporation of parent-report sleep metrics.

IMPACT

Parental-reported sleep problems are common in autism spectrum disorder (ASD). We investigated whether the inclusion of parental-reports of infant/toddler sleep patterns enhanced the effectiveness of developmental screening for autism. We reported higher rates of difficulty falling asleep and resisting bedtime during infancy and toddlerhood among children later diagnosed with ASD; however, we did not find an improvement in ASD developmental screening through the incorporation of parent-report sleep metrics. In our sample, the standard M-CHAT-R had a sensitivity of 39% among children of mothers with government insurance compared with a sensitivity of 53% among children of mothers with employer-based insurance.

Prematurity has no impact on the quality of parents' sleep 6 months after birth

AIM

Due to the stress that is classically associated with the premature birth of a child, these parents may be prone to sleep disorders. The aim of this study was to compare sleep quality of preterm infants' parents with that of term infants' parents.

METHODS

Prospective observational cohort study conducted at the University Hospital of Brest between January 2019 and January 2021. The primary outcome criterion was the score obtained by the parents on the Pittsburg Sleep Quality Index (PSQI) 6 months after their child's birth. Each parent was recruited in the days following their child's birth and completed the PSQI online.

RESULTS

Overall, 316 parents were included. The median gestational age at birth was 34.3 (31.6-35.5) weeks in the preterm infant group and 39.7 (38.6-40.7) weeks in the term infant group. Of the 948 expected questionnaires, 771 were completed and collected. On average, 59% of the parents obtained a PSQI global score >5. Six months after birth, no differences were reported between parents of preterm and full-term infants.

CONCLUSION

This study did not reveal any difference between sleep quality of preterm infants' parents and term infants' parents.

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.

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.

Sleep as a protective factor of children's executive functions: A study during COVID-19 confinement

Confinements due to the COVID-19 outbreak affected sleep and mental health of adults, adolescents and children. Already preschool children experienced acutely worsened sleep, yet the possible resulting effects on executive functions remain unexplored. Longitudinally, sleep quality predicts later behavioral-cognitive outcomes. Accordingly, we propose children's sleep behavior as essential for healthy cognitive development. By using the COVID-19 confinement as an observational-experimental intervention, we tested whether worsened children's sleep affects executive functions outcomes 6 months downstream. We hypothesized that acutely increased night awakenings and sleep latency relate to reduced later executive functions. With an online survey during the acute confinement phase we analyzed sleep behavior in 45 children (36-72 months). A first survey referred to the (retrospective) time before and (acute) situation during confinement, and a follow-up survey assessed executive functions 6 months later (6 months retrospectively). Indeed, acutely increased nighttime awakenings related to reduced inhibition at FOLLOW-UP. Associations were specific to the confinement-induced sleep-change and not the sleep behavior before confinement. These findings highlight that specifically acute changes of children's nighttime sleep during sensitive periods are associated with behavioral outcome consequences. This aligns with observations in animals that inducing poor sleep during developmental periods affects later brain function.

Changes in parental sleep from pregnancy to postpartum: A meta-analytic review of actigraphy studies

Sleep changes in new parents are widely observed but there is no extant meta-analysis of changes to sleep parameters in this group. We completed a meta-analysis of changes in actigraphy-measured parent sleep between pregnancy and the end of the first year of a child's life. A search of six databases was completed. Following review using predetermined inclusion and exclusion criteria, 16 papers were left for review. Data were extracted, analysed and each paper was reviewed for methodological quality. Where possible, subgroup analysis was completed based on time since birth and location of the study, and meta-regression of parent age. Parents' total sleep time and sleep efficiency were shown to decrease following the birth of a child, with wake after sleep onset increasing. This change was most notably observed in the first four weeks after birth. Up to 16 weeks post-birth, differences were still apparent, but sleep parameters were beginning to return to pre-birth levels. New parents experience a significant change in multiple sleep parameters following the birth of a child. Future data collection, using best practice actigraphy measurement, reporting a broader range of variables and including fathers, as well as mothers, is warranted.

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.

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.

Family-building and parenting considerations for people with cystic fibrosis

As people with cystic fibrosis (CF) live longer and healthier lives, increasing numbers are considering the full range of reproductive options for their futures, including parenthood, pregnancy, or pregnancy prevention. As the face of CF changes, the CF care model must adapt to meet the reproductive health needs of both parents and nonparents with CF. This article summarizes the reproductive goals and family-building concerns faced by people with CF, including fertility, pregnancy, and alternative paths to parenthood, the impact of parenthood on mental and physical health, and important future research.

Fathers' experiences of supporting their partners during their preterm infant's stay in the neonatal intensive care unit: a multi-method study

OBJECTIVE

To explore how the fathers experience their role as a support for their partner and the relationship with them during their preterm infant's stay in the NICU.

STUDY DESIGN

Multi-method longitudinal study involving ethnographic observation, semi-structured interviews, self-report questionnaires, and clinical information. Twenty fathers of preterm infants hospitalized in a level-III-NICU were included. Data were analyzed using thematic continent analysis.

RESULTS

Three main themes were identified: support for mother (subthemes: putting mother's and infant's needs first; hiding worries and negative emotions; counteracting the sense of guilt; fear that the mother would reject the child), mother's care for the infant (subthemes: observing mother engaged in caregiving; mother has "something extra"), and couple relationship (subthemes: collaboration; bond).

CONCLUSION

Fathers supporting their partners during the stay in the NICU experience emotional distress and the need for being supported that often are hidden. This demands a great deal of emotional and physical energy.

Overview of clinical trial protocols for behavioral insomnia in infants

OBJECTIVE

to describe the overview of clinical trial protocols for behavioral insomnia in infants.

METHODS

an analytical study that reviewed protocols registered with the International Clinical Trials Registry Platform between August and September 2019, aiming to identify the interventions for behavioral insomnia in infants, the comparators, the main primary, secondary outcomes and their respective measurements.

RESULTS

eleven protocols registered between 2004 and 2018 were included. Nurses were the main coordinators of protocols (45.5%), with proposals using educational technologies, one-to-one and online follow-up consultations. The main outcome was improvement of infant and maternal sleep patterns. Secondary outcomes were anxiety, depression, and parental sexual satisfaction. To measure them, the following were used: sleep diary (54.5%), actigraphy (45.4%), and the Pittsburgh Sleep Quality Interview (36.3%) and Extended Brief Infant Sleep Questionnaire (27.2%) were used.

CONCLUSION

the protocols proposed interventions for independent sleep, aiming at quality of sleep for the whole family.

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.
