Group-based multi-trajectory modelling was used to identify maternal, paternal and couple sleep multi-trajectory groups among 188 couples reporting sleep data for at least 2 time points. Multinomial logistic regression was used to assess associations between parental sleep multi-trajectories and early characteristics such as sociodemographic, chronotypes, child sex, birth seasonality or breastfeeding duration.Results: We identified three maternal (M1-M3), paternal (F1-F3) and couple (C1-C3) sleep multi-trajectory groups with similar characteristics: a group with short NSD and high SSL prevalence (M1, F2, C2), a group with long NSD but medium SSL prevalence (M2, F3, C3) and a group with long NSD and low SSL prevalence (M3, F1, C1). Mothers with the shortest NSD (M1) were less likely to have a partner with long NSD (F2). As compared with long NSD and low SSL prevalence (C1), couples with short NSD and high SSL prevalence (C2) were less likely to have had a first child born in the autumn and fathers in C2 had a later chronotype.Conclusion: We identified distinct sleep multi-trajectory groups for mothers, fathers and couples from 3- to 36-month postpartum. Sleep patterns within couples were homogeneous.Keywords: multi group-based-trajectory modelling, parental sleep, sleep epidemiology, sleep interrelation

Although sleep problems are highly prevalent in infants, the intrinsic and extrinsic factors that influence sleep consolidation and regulation in this age group are not well understood. This study aimed to examine the cross-sectional associations of demographic and parental factors with infant sleep characteristics. Participants were 97 Canadian mother-infant dyads primarily from Edmonton, Alberta. Demographic factors (e.g., infant age), parenting practices (e.g., sleep position, sleep initiation methods), and infants sleep characteristics (e.g., the frequency of nighttime awakenings) were assessed using the Brief Infant Sleep Questionnaire. Maternal sleep characteristics (e.g., nighttime sleep duration) were assessed using Actigraph accelerometers. Infant age (mean = 4.24 ± 2.90) was associated with most infant sleep characteristics. In multiple regression models for infant nighttime sleep duration, after removing influential observations, a negative association for side (vs. prone) sleep position was, respectively, observed. In multiple regression models for the frequency of nighttime awakenings in infants, positive associations for infants falling asleep while feeding (vs. in bed alone) and side (vs. prone) sleep position were consistently observed after removing influential observations. Lower nighttime sleep efficiency (B = − 0.08, 95%CI: − 0.13, − 0.02) and longer nighttime wake after sleep onset (B = 1.03, 95%CI: 0.41, 1.65) in mothers were associated with more frequent nighttime awakenings in infants. After removing influential observations, more frequent nighttime awakenings (B = 0.35; 95%CI: 0.09, 0.61) and longer total sleep duration (B = 0.33, 95%CI: 0.11, 0.55) in mothers were also associated with more frequent nighttime awakenings in infants. Sleep initiation methods with less parental involvement, and more continuous and efficient maternal nighttime sleep, tended to be associated with less interrupted infant sleep.

Abstract 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.

Sleep is an important biological necessity, a lack of which can have many cognitive, psychological, social, and physical impacts. Children with autism are known to present with sleep difficulties more frequently than their typically developing peers but despite this, there is relatively little research looking at the impact of sleep on the family. To investigate the effect of sleep on families of autistic and typically developing (TD) children, we conducted a study of sleep disturbances among children, sleep quality of their parents in association with their family function. In our study, 239 parents of autistic children and 227 parents of TD children participated. These parents completed a survey about their child's sleep disturbances, their own sleep quality, and their family function, along with a series of demographic questions. Analyses indicated that autistic children experience more sleep difficulties than TD peers, that children's sleep disturbances are associated with parental sleep quality and that parents of autistic children report decreased sleep quality compared to parents of TD children. Parental sleep quality, and child sleep quality were both found to partially mediate the relationship between autism diagnosis and family function. [ABSTRACT FROM AUTHOR]

Child eveningness has been associated with many adverse outcomes for children. The aim of this study was to assess whether child eveningness poses a risk to parental sleep quality in follow-up. A total of 146 children (57% adopted, 47% boys, mean age at follow-up 5.1 years [standard deviation 1.7]) completed a 1-week actigraph recording to analyze their sleep twice, 1 year apart. The parents completed the Child ChronoType Questionnaire for their child and a short version of the Morningness–Eveningness Questionnaire for themselves and the Jenkins Sleep Scale for their sleep quality. Linear regression analyses showed that subjective parental sleeping problems at baseline were associated with subjective parental sleeping problems at follow-up. A morning-type child decreased the risk of parental sleeping problems at the 1-year follow-up compared to the child evening chronotype. Additionally, the child intermediate chronotype decreased the risk of maternal sleeping problems at the 1-year follow-up compared to the evening chronotype of the child. Parents of evening-type children experienced more sleeping problems in the follow-up, compared to parents of morning-type children. This finding encourages parents and professionals to steer the diurnal rhythm of evening-type children toward an earlier daily routine. [ABSTRACT FROM AUTHOR]

However, most research about the effect of infant and young child sleep on parenting has focused on mothers. Therefore, the present study aimed to explore the perception and consequences of infant and young child sleep problems of both parents.Participants and Methods: Participants were recruited via random sampling at, eg, kindergartens in North Rhine Westphalia. The sample includes data of heterosexual German-speaking couples with children without any medical or psychopathological problems. For this study, parents were asked to complete the test battery with regard to their youngest child. As sampling was via the kindergarten, the range of child age was 4– 68 months. A survey assessed data of parents (N=196, 46% female). The test battery contained the following questionnaires: Children Sleep Habits Questionnaire (CSHQ), Pittsburgh Sleep Quality Index (PSQI), Self-Report Measure for the Assessment of Emotion Regulation Skills (SEK-27), and a German version of the Infant Sleep Vignettes Interpretation Scale (ISVIS). For the outcome variables of parental sleep as well as for parental emotional competence, the statistical tests of ANOVA were used, and for parental sleep-related cognitions with the grouping variables of infant and young child sleep as well as parental gender, a MANOVA was used. According to the analysis of group differences, the age of the child was also included additional to the grouping variable of parental gender and children’s sleep.Results: Mothers and fathers in this sample were equally aware of their children’s sleep problems and reported similar sleep quality and emotion regulation themselves (all p > 0.05). Mothers as well as fathers of children with sleep problems had lower parental sleep quality (F(1, 183) = 110.01, p < 0.001) and emotion regulation (F(1, 184) = 143.16, p < 0.001) compared to parents of children without sleep problems. In children under 26 months of age, the child’s age seemed to have less negative impact on the father’s sleep quality (F(1, 183) = 5.01, p < 0.001) and emotion regulation (F(1, 184) = 0.72, p < 0.05) than on the outcomes of the mother. With regard to sleep-related cognition, there were statistically significant effects of parental gender (F(2, 185) = 44.39, p < 0.001) and interaction effects of parental gender × child sleep problems observed (F(2, 185) = 31.91, p < 0.001).Conclusion: The conclusion from this survey refers to the role of the father. According to the results, an association between paternal emotional competence, sleep quality as well as their sleep-related cognitions and infants and toddlers sleep behavior could be assumed in addition to and independent of the results of mothers. We would highlight the urgent need of inclusion of fathers in infant and developmental sleep research. In the context of sleep intervention, both parents should be provided with ongoing support to improve their sleep quality and competence in emotion regulation.Keywords: infant and young child sleep, parental sleep, parental emotion regulation, parental cognitions

Sleep is a common challenge for parents with sick children and can impact parents' health, wellbeing, and caregiving responsibilities. Despite the vast research around parental sleep when their child is sick, the concept is not clearly defined. A phased principle‐based concept analysis that includes triangulation of methods and quality criteria assessment was used to explore how the concept is described, used, and measured in the current literature. The aim was to analyse and clarify the conceptual, operational, and theoretical basis of parental sleep when their child is sick to produce an evidence‐based definition and to identify knowledge gaps. A systematic literature search including databases CINAHL, Embase, MEDLINE, PsychARTICLES, PsychINFO, Pubmed, Scopus and Web of Science, identified 546 articles. The final dataset comprised 74 articles published between 2005 and 2021 and was assessed using a criteria tool for principle‐based concept analysis. Data were managed using NVivo, and thematic analysis was undertaken. A precise definition is not present in the literature. Various tools have been used to measure parents' sleep, as well as exploration via interviews, open‐ended questions, and sleep diaries. The terminology used varied. Parental sleep when their child is sick is interrelated with other concepts (e.g., stress). A recommended definition is offered. A conceptual understanding of parental sleep when their child is sick will help to guide translational research and to conduct studies critical to clinical practice and research. Future research includes developing a measurement tool for parental sleep when their child is sick to be used in study design and future interventions. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effects of parental sleep and work arrangements on children's sleep duration during the national lockdown period, referred to as 'Circuit Breaker' (CB), due to COVID-19.Methods: Cross-sectional, anonymous, online questionnaire to parents with school-going children aged between 3 and 16 years. Child and parental sleep duration in relation to change in parental work arrangements, housing type and number of individuals in the household as reported by parents were evaluated. Descriptive statistics and tests of comparison were used to evaluate data.Results: School-going children (n = 593) had a mean age of 8.68 (SD = 3.65; median 7) years. Both, fathers and mothers had gains in sleep during CB (based on self-reported sleep data), compared to pre-CB. Change in both maternal and paternal sleep duration positively correlated with change in child sleep duration (based on parent-reported sleep data) among all children (r2 = 0.27, p < 0.001 and r2 = 0.17, p < 0.001 respectively); pre-schoolers mirrored their mothers' sleep more closely. Parents who changed to working from home during the CB (compared to working from outside home previously) had the greatest gains in sleep during this period. Housing type was not significantly associated with change in child sleep duration from pre-CB to CB.Conclusions: Greater gains in sleep in parents was associated with working from home during CB. Child sleep duration mirrored gains in parental sleep, especially in pre-school and primary-school-going children. Optimising parental sleep may therefore be one of the means to improve child sleep.

Study Objectives: The coronavirus disease 2019 (COVID-19) pandemic impact on infant sleep (IS) is understudied. The purpose of this study was to examine the relationships between family impact and distress from COVID-19 pandemic stressors, parental insomnia symptoms, infant temperamental negative affectivity, and parent-reported IS., Methods: Parents from the Phoenix metropolitan area with a full-term healthy infant (<1 year) were recruited from February 27, 2021, to August 7, 2021. A sample of 70 parents (baby age 5.5 ± 3.5 months; parental age: 31.7 ± 5.0 years) completed the COVID-19 Exposure and Family Impact Survey (CEFIS) Impact and Distress scales, the Insomnia Severity Index (ISI), the Infant Behavioral Questionnaire-Revised Negative Affectivity subscale (IBQ-R-NA), and the Brief Infant Sleep Questionnaire-Revised (BISQ-R). Based on the transactional model of IS, path analyses were conducted to identify the direct effect of CEFIS scores and the indirect effects of parental ISI and infant IBQ-R-NA scores on BISQ-R scores., Results: The parent sample was predominantly female (94.3%), white (72.9%), and married or in a domestic partnership (98.6%). Although COVID-19 pandemic impact and distress were not directly related to parent-reported IS, pandemic distress was negatively related to parent-reported IS indirectly through infant negative affectivity, including BISQ-R total score (β = -0.14, 95% CI [-0.32, -0.01]) and IS subscale score (β = -0.12, 95% CI [-0.27, -0.01])., Conclusions: Heightened COVID-19 pandemic family distress was related to poorer parent-reported IS through greater parent-reported infant negative affectivity, suggesting the importance of addressing family stress and emotional regulation during crises., (© The Author(s) 2024.

Background: Parents commonly experience anxiety, worry, and psychological distress in caring for newborn infants, particularly those born preterm. Web-based therapist services may offer greater accessibility and timely psychological support for parents but are nevertheless labor intensive due to their interactive nature. Chatbots that simulate humanlike conversations show promise for such interactive applications. Objective: The aim of this study is to explore the usability and feasibility of chatbot technology for gathering real-life conversation data on stress, sleep, and infant feeding from parents with newborn infants and to investigate differences between the experiences of parents with preterm and term infants. Methods: Parents aged =21 years with infants aged =6 months were enrolled from November 2018 to March 2019. Three chatbot scripts (stress, sleep, feeding) were developed to capture conversations with parents via their mobile devices. Parents completed a chatbot usability questionnaire upon study completion. Responses to closed-ended questions and manually coded open-ended responses were summarized descriptively. Open-ended responses were analyzed using the latent Dirichlet allocation method to uncover semantic topics. Results: Of 45 enrolled participants (20 preterm, 25 term), 26 completed the study. Parents rated the chatbot as "easy" to use (mean 4.08, SD 0.74; 1=very difficult, 5=very easy) and were "satisfied" (mean 3.81, SD 0.90; 1=very dissatisfied, 5 very satisfied). Of 45 enrolled parents, those with preterm infants reported emotional stress more frequently than did parents of term infants (33 vs 24 occasions). Parents generally reported satisfactory sleep quality. The preterm group reported feeding problems more frequently than did the term group (8 vs 2 occasions). In stress domain conversations, topics linked to "discomfort" and "tiredness" were more prevalent in preterm group conversations, whereas the topic of "positive feelings" occurred more frequently in the term group conversations. Interestingly, feeding-related topics dominated the content of sleep domain conversations, suggesting that frequent or irregular feeding may affect parents' ability to get adequate sleep or rest. Conclusions: The chatbot was successfully used to collect real-time conversation data on stress, sleep, and infant feeding from a group of 45 parents. In their chatbot conversations, term group parents frequently expressed positive emotions, whereas preterm group parents frequently expressed physical discomfort and tiredness, as well as emotional stress. Overall, parents who completed the study gave positive feedback on their user experience with the chatbot as a tool to express their thoughts and concerns. [ABSTRACT FROM AUTHOR]

Objective: Previous research has demonstrated a link between childhood anxiety and sleep problems, but little is known about the link between these difficulties and parental sleep disturbances. The purpose of the current study was to explore the association between anxious children's sleep difficulties and those of their mothers.Method: A total of 101 children aged 8-18 years and their mothers participated in this study. The clinical group included 66 children (mean age = 11.45 years, standard deviation = 2.79 years) diagnosed with anxiety disorders, and the control group included 35 age- and sex-matched normal healthy controls. Mothers completed questionnaires assessing their child's anxiety and sleep, as well as their own sleep. Children completed questionnaires assessing anxiety, sleep, depression, and obsessive symptoms.Results: Both children and mothers in the clinical group exhibited more sleep difficulties compared to controls. A regression analysis revealed that pre-sleep arousal negatively predicted children's sleep. Furthermore, children's anxiety level was associated with parental levels of sleep disturbances. This link was fully mediated by the children's sleep disturbances score.Conclusion: Mothers of children with anxiety disorders exhibit higher levels of sleep disturbances than controls. These difficulties are linked to children's anxiety and sleep problems. When treating children with anxiety, it is therefore important to assess their overall sleep disturbances, as well as parental sleep difficulties, and when appropriate to add a specific sleep intervention component.

Aim: Parental obesity is the predominant risk factor for child obesity. We compared sleep in one-year-old children with different obesity risks, based on parental weight, and explored associations with weight, parental sleep and family factors.Methods: Baseline data from 167 families participating in a longitudinal obesity prevention programme was used. Sleep patterns were compared between groups with high and low obesity risks, based on parental weight, and associations between child sleep and weight status, family obesity risk and parental sleep were explored. Sleep was assessed using child sleep diaries and standard parental questionnaires.Results: Later bedtime, longer sleep onset latency and lower sleep efficiency were observed among children in the high-risk group. Child sleep onset latency was associated with the family obesity risk (β = 0.25, p = 0.001), child bedtime with both maternal (β = 0.33, p < 0.01) and paternal bedtime (β = 0.22, p < 0.05) and child sleep efficiency with maternal sleep quality (β = 0.20, p < 0.01). The child's bedtime was weakly associated with their body mass index (β = 0.17, p < 0.05).Conclusion: Sleep differed between one-year-old children with high or low obesity risks, based on their parents' body mass index, and was associated with the family obesity risk and parental sleep. The child's bedtime was weakly associated with their weight status. [ABSTRACT FROM AUTHOR]

Study Objectives: Congenital central hypoventilation syndrome (CCHS) is a rare disease characterized by impaired control of breathing caused by paired-like homeobox 2B ( PHOX2B ) gene variants, necessitating lifelong assisted ventilation (AV). This study aimed to assess sleep quality in patients with CCHS and their parents using sleep questionnaires., Methods: Parents of patients with CCHS completed the Pittsburgh Sleep Quality Index (PSQI) regarding their sleep and the Sleep Disturbance Scale for Children (SDSC) regarding their child's sleep., Results: Twenty participants completed the questionnaires. The median (interquartile range) ages of the parents and patients were 41.5 (38.5-51.5) and 11.5 (7.4-16.7) years, respectively. The median (interquartile range) PSQI and SDSC scores were elevated at 6.5 (4-10) and 41.5 (34-51.5), respectively, suggesting that parents and patients with CCHS can experience sleep disturbances and poor sleep quality. There were no significant differences in SDSC ( P = 1.0) and PSQI ( P = .76) scores for AV with or without tracheostomy. Similarly, there were no significant differences in SDSC ( P = .22) and PSQI ( P = .34) scores based on PHOX2B genotypes. There was a moderately strong, significant, and positive correlation between the CCHS SDSC scores and parental PSQI scores ( r = .48, P = .03), suggesting that sleep disturbances in patients with CCHS were associated with poor parental sleep quality. There was no difference in the median parental sleep duration between those with and without nighttime home nursing ( P = .09)., Conclusions: Patients with CCHS and their parents are at risk for sleep disturbances regardless of their AV modality and PHOX2B genotype. In addition to AV management, patients with CCHS and their parents should be assessed for sleep disturbances., Citation: Finch CE, Leu RM, Harford K-L, Westbrook AL, Kasi AS.

Objective: Although sleep problems are widely known to be a prominent feature of childhood attention deficit/hyperactivity disorder (ADHD), little is known about the link between these difficulties and parental sleep disturbances.Methods: The design was cross-sectional assessing a clinical sample of 62 children, aged 7-17 years (mean age = 10.0 years) diagnosed with ADHD and their parents. All participants completed measures of ADHD symptoms, sleep, anxiety, and executive functioning.Results: Regression analysis revealed that child's pre-sleep arousal significantly predicted parental sleep, and that medication status and children's anxiety significantly predicted children's sleep. Children with a clinical sleep score were more impaired in behavioral, emotional, and cognitive domains.Conclusion: Parents of children with ADHD exhibit sleep disturbances that might be affected by their child's arousal prior to bedtime. The nature of the interaction between children with ADHD and their parents' sleep abnormalities is yet to be elucidated. [ABSTRACT FROM AUTHOR]
