Infant sleep, parental sleep and parenting stress in families of mothers on maternity leave and in families of working mothers

Sleep and adjustment in foster environments for toddlers and preschoolers (SAFE-T): Initial efficacy of a trauma-informed sleep intervention for young children in foster care

BACKGROUND

This study presents findings from a randomized controlled trial of Sleep and Adjustment in Foster Environments for Toddlers and Preschoolers (SAFE-T), a telehealth-delivered, trauma-informed sleep intervention for children in or adopted from foster care.

METHODS

N = 45 caregivers of children aged 2 to 5 years (M = 4.01; SD = 1.04) were randomized to SAFE-T or Sleep Education Support (SES), an active control condition. Assessments, including one-week parent-report sleep diaries, were completed at pre- intervention, post- intervention, and 3 months follow-up.

RESULTS

Results indicated improvements in multiple sleep outcomes at post-intervention and three months later, including nighttime sleep duration, nighttime awakenings, and overall sleep problems in the SAFE-T group only. Sleep-based improvements were largely maintained or strengthened over time. Several secondary outcomes, including child emotional and behavior problems and parenting stress, also improved considerably in the SAFE-T but not the SES group.

CONCLUSIONS

Findings suggest SAFE-T to be a promising intervention for improving sleep health among children currently or previously placed in foster care.

Maternal Sleep Quality and Executive Function are Associated with Perceptions of Infant Sleep

OBJECTIVES

This study examined the associations among maternal sleep quality, executive function, and perceptions of infant sleep in a sample of families recruited from human service and public health systems.

METHODS

Seventy-three mothers of infants 5-14 months old were included in the study. Mothers racially and ethnically identified as American Indian/Alaskan Native (4.1%), Asian (4.1%), Black/African American (12.3%), Latina (23.3%), more than one race (12.3%), Pacific Islander (1.4%), and White (42.5%). Mothers completed questionnaires assessing their own sleep (Pittsburgh Sleep Quality Index) and executive function (Behavior Rating Inventory of Executive Function) as well as their perceptions about their infant's sleep (Brief Infant Sleep Questionnaire).

RESULTS

Results of the path analysis indicated significant direct effects among maternal sleep quality, executive function, and perceptions of infant sleep. Significant indirect effects were found such that poor maternal sleep quality was linked to poorer perceptions of infant sleep through maternal executive dysfunction, adjusting for infant sleep patterns, infant age, and maternal race and ethnicity.

CONCLUSIONS

The current study highlights the potential role of maternal behavioral and cognitive factors in shaping mothers' perceptions about infant sleep. These findings support the need for health professionals and researchers to consider maternal sleep quality and executive function when addressing mothers' concerns about infant sleep.

The relationships between the family impact and distress of the coronavirus disease-19 pandemic, parent insomnia, infant temperamental negative affectivity, and parent-reported infant sleep: a path analysis

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.

Parents' Sleep Multi-Trajectory Modelling from 3 to 36 Months Postpartum in the SEPAGES Cohort

Objective

We investigated maternal and paternal sleep evolution from 3 to 36 months postpartum, their interrelations and predictors in the SEPAGES cohort.

Methods

Sleep information (night sleep duration [NSD], weekend daytime sleep duration [DSD] and subjective sleep loss [SSL]) was collected by self-administered questionnaires at 3, 18, 24 and 36 months postpartum in the SEPAGES French cohort that included 484 mothers and 410 fathers. 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.

The SAFE study: Stress and fatigue control by exercise: Acute and long-term effects of aerobic exercise in lactating employed mothers

BACKGROUND

Stress and fatigue experienced by lactating employed mothers can affect mothers' and babies' mental and physical health detrimentally. Aerobic exercise is known to control stress and fatigue, but the dosages of the exercises needed to maintain long-term effects are still under investigation.

OBJECTIVE

This study aimed to investigate the acute and long-term effects of aerobic exercise on controlling stress and fatigue in lactating, employed mothers.

METHODS

This randomized control study involved sixty lactating, employed mothers suffering from stress and fatigue. They were divided into two groups: Group A received five sessions of 30-minute aerobic training on a treadmill per week, in addition to lifestyle modification advice for six weeks. Group B received the same lifestyle routine advice for the same duration without being trained. Assessments of stress and fatigue levels were done before, after 6 weeks, and after 6 months from the baseline assessments using the Perceived Stress Scale (PSS-10) and Fatigue Assessment Scale (FAS), respectively.

RESULTS

Post-six-week comparisons within and between both groups showed a significant decline in PSS-10 and FAS in group A compared with group B (p < 0.001); however, after six months of follow-up, there were statistically significant effects within groups only (p < 0.05) and no statistically significant difference between groups at both variables (p > 0.05).

CONCLUSION

Aerobic exercises for 6 weeks can induce an acute but not long-term effect on stress and fatigue control in lactating-employed mothers. Future research is needed to tailor the exercise prescription needed to maintain training's long-term benefits.

Does the feeding method affect the quality of infant and maternal sleep? A systematic review

Breastfeeding brings many benefits to both mother and infant. Although, many women stop breastfeeding their infants too soon. The perceived association between breastfeeding and sleep may influence their decision to terminate breastfeeding. In our systematic review, we focused on mapping the relationship between infant feeding method and total sleep time (TST), number of nocturnal awakenings, awakenings after sleep onset (WASO) of mothers and infants and sleep quality of mothers. We searched four databases according to selected keywords and inclusion criteria - articles published in peer-reviewed journals between 2012 and 2022; English language; a sample consisting of mothers, infants, or both (without psychiatric and health problems); a comparison of the sleep quality of breastfed and formula-fed children or breastfeeding and formula-fed mothers. We read 260 full texts of selected articles. A total of 35 articles were included in this review. Due to significant heterogeneity, meta-analysis was not possible to accomplish. The results are processed according to narrative synthesis. Most studies agree that breastfed infants wake up more often at night. Total sleep time and time spent awake during the night (WASO) did not differ between breastfed and non-breastfed infants. We observed identical results in sleep variables among mothers. Additionally, there was no difference in maternal sleep quality. The synthesis revealed that the results may have differed due to using subjective, objective methods or the infant's age. It is important to remember that night waking is a more complex concept. Infants wake for many reasons, not just due to breastfeeding. The narrative synthesis indicated that the chosen study design, measurement method, the variables, and the infant's age could influence outcomes. In addition, other variables appeared that may affect the entire process. Therefore, we recommend that attention be paid to this in future studies.

Effects of psychosocial sleep interventions on improving infant sleep and maternal sleep and mood: A systematic review and meta-analysis

Infant sleep problems are prevalent and have a negative impact on infant growth and development, maternal sleep, and maternal mood. The effects of psychosocial sleep interventions on infant sleep and maternal sleep and mood are unclear. This study aimed to systematically evaluate the effects of psychosocial sleep interventions on improving infant sleep, including nocturnal total sleep time, daytime total sleep, total sleep time, night wakings, and maternal sleep and mood problems (ie, depression and fatigue). We searched PubMed, Web of Science, Cochrane Library, Embase, EBSCO, OpenGrey, DeepBlue, China National Knowledge Infrastructure, and Wanfang databases. We focused on randomized controlled trials examining the effectiveness of psychosocial sleep interventions on infant sleep. The study was preregistered at the International Prospective Register of Systematic Reviews (CRD42022301654). Thirteen studies from 5889 articles were included in the review, which found that psychosocial sleep interventions improved infant nocturnal total sleep time (0.28 [0.04-0.52], p < 0.05, I2 = 83.9%) and maternal depression (-0.10 [-0.28 to -0.08], p < 0.05, I2 = 8.7%). To test and explore heterogeneity, we used the I2 statistic, influence analysis, subgroup analyses, and subgroup meta-analyses. Funnel plots and Egger's tests revealed no evidence of publication bias. Psychosocial sleep interventions improved infant nocturnal total sleep time and maternal depression. Future research should include more randomized controlled trials examining the effect of psychosocial sleep interventions on the improvement of maternal sleep and fatigue.

Sleep of mothers, fathers, and infants: a longitudinal study from pregnancy through 12 months

STUDY OBJECTIVES

This study assessed and compared mothers' and fathers' sleep trajectories from pregnancy and throughout the first year of the infant's life. We also examined associations between maternal, paternal, and infant sleep.

METHODS

Two hundred and thirty-two couples were recruited for the study during pregnancy. Data were collected during pregnancy and at 4, 8, and 12 months postpartum. Maternal, paternal, and infant sleep were monitored at home for seven nights, using actigraphy, sleep diaries, and the Insomnia Severity Index (ISI).

RESULTS

Mothers showed more impaired sleep quality than fathers, at all assessments, whereas fathers had shorter sleep duration. Based on the ISI, about 70% of mothers and 50% of fathers showed at least subclinical insomnia at the different assessments. Trajectory analyses (controlling for feeding method and sleeping arrangements) demonstrated a significant deterioration in diary-based and actigraphy sleep quality for both parents, from pregnancy to 4 months. Both parents and infants had an increase in sleep quality from 4 to 12 months, though some parental sleep variables showed a quadratic pattern with a decrease in sleep quality at 8 months. Statistically significant triadic associations at the different assessments were found between mothers', fathers', and infants' sleep. Maternal and infant sleep measures were more strongly correlated than paternal and infant sleep.

CONCLUSIONS

The findings highlight the importance of considering the family context of sleep, by demonstrating similarities and differences in the changes that sleep undergoes in new mothers and fathers and by showing how sleep is interrelated between all family members.

Caregiver Perceived Stress and Child Sleep Health: An Item-Level Individual Participant Data Meta-Analysis

Up to 50% of children and adolescents in the United States (U.S.) experience sleep problems. While existing research suggests that perceived stress in caregivers is associated with poorer sleep outcomes in children, research on this relationship is often limited to infant and early childhood populations; therefore, we investigated this association in school-age children and adolescents. We used cross-sectional caregiver-reported surveys and applied item response theory (IRT) followed by meta-analysis to assess the relationship between caregiver perceived stress and child sleep disturbance, and moderation of this relationship by child age and the presence of a child mental or physical health condition. We analyzed data from the National Institutes of Health (NIH) Environmental influences on Child Health Outcomes (ECHO) Program, a collaboration of existing pediatric longitudinal cohort studies that collectively contribute a diverse and large sample size ideal for addressing questions related to children's health and consolidating results across population studies. Participants included caregivers of children ages 8 to 16 years from four ECHO cohorts. Caregiver perceived stress was measured using the Perceived Stress Scale (PSS), and child sleep disturbance was assessed using five sleep-related items from the School-Age version of the Child Behavior Checklist (CBCL). Increases in caregiver perceived stress and child mental or physical health condition were independently associated with greater sleep disturbance among children. The findings reinforce the importance of accounting for, and potentially intervening on, the broader family context and children's mental and physical health in the interest of improving sleep health.

The Relationship Between Maternal and Infant Sleep Duration Across the First Two Years

OBJECTIVES

The first objective of this study was to determine how mother-infant sleep duration is related across the first 2 years of life. The second objective was to determine whether these relationships change across the first 2 years of life. The third objective was to understand demographic and health predictors of the relationship between maternal and child sleep.

METHODS

Parents of 464 infants from the STRONG Kids 2 study reported their own and infants' nocturnal sleep duration and other health information (i.e., breastfeeding) at 3, 12, 18, and 24 months postpartum.

RESULTS

Latent transition models revealed 2 mother-infant sleep profiles exist at 3 to 24 months. The low maternal sleep ( LMS ) pattern was characterized by lower maternal sleep duration than the recommended amount and lower infant sleep duration. The average maternal sleep ( AMS ) pattern was characterized by average maternal sleep duration meeting the recommended standard and average infant sleep duration. Approximately half of the mothers who started in the LMS profile transitioned to the AMS profile after 12 months postpartum. The sleep profiles stabilized after 12 months postpartum with limited transitions across 12 to 24 months. More infant-signaled nighttime wakings, later bedtimes, more infant sleep problems, and more exclusive breastfeeding were predictors of being in the LMS profile.

CONCLUSION

Mother-infant sleep profiles stabilized after age 12 months, and mother-infant sleep profiles are driven by infant sleep quality during the night. The findings suggest the need to establish a healthy sleep routine for mothers and infants in the first year of life to promote longer-term sleep hygiene.

Length of Maternity Leave Impact on Mental and Physical Health of Mothers and Infants, a Systematic Review and Meta-analysis

BACKGROUND

Recent legislative decisions in the United States have encouraged discussion about national parental leave programs. Currently, over 47% of the United States workforce is female. However, the United States is the only nation of the 37 member countries in the Organization for Economic Co-Operation and Development (OECD) to have no national requirement for maternity leave. The first few months of a child's life are vital to their physical and mental development. Likewise, a gradual return to pre-partum functioning is important for a newly postpartum woman. While it has been shown that maternity leave positively impacts various measures of maternal and infant mental and physical health, we lack consensus on the optimal length of paid or unpaid maternity leave. Accordingly, we conducted a systematic review and meta-analysis to evaluate the optimal length of paid or unpaid maternity leave to encourage maternal and infant mental and physical health in the United States.

METHODS

A systematic review and meta-analysis were conducted to synthesize and critically evaluate the current research investigating the association between maternity leave and maternal and infant mental and physical health using the Preferred Reporting in Systematic Reviews and Meta-Analyses guidelines. Databases EMBASE, PsycInfo, and PubMed were searched using specific inclusion and exclusion criteria. Methodological Index for Non-Randomized Studies scale assessed the methodological quality of the included eligible studies. The magnitude of heterogeneity between-study was tested using The Cochrane χ² test and the Moran's I² statistic. Possible publication bias was assessed through the funnel plot and the Egger regression test. A p-value of < 0.10 will be considered as an indication for the existence of potential publication bias. All statistical analyses were carried out with Stata software version 15.

RESULTS

A total of 21 studies were analyzed. It was found that longer maternity leave may decrease rates of maternal mental and physical health complaints. It was also found that longer maternity leave leads to more positive mother-child interactions, decreased infant mortality, and longer periods of breastfeeding.

CONCLUSION

Maternity leave of 12 weeks or more confers the greatest benefit for mothers and their infants.

Maternal insomnia and depressive symptoms and early childhood sleep among Arab and Jewish families in Israel

OBJECTIVES

The present study explored the links between maternal insomnia symptoms, maternal depressive symptoms, and young children's sleep quality among two major cultural groups in Israel: Arab and Jewish. We also assessed the prevalence of maternal insomnia and depressive symptoms, in both cultural groups.

METHODS

Mothers of 497 healthy, typically developing infants and toddlers, ranging in age from 3-36 months, participated in the study: 253 of the mothers were Arab and 244 were Jewish. Mothers completed the Insomnia Severity Index (ISI), the Edinburgh Postnatal Depression Scale (EPDS), and the Brief Infant Sleep Questionnaire.

RESULTS

For both cultural groups, there were significant positive associations between maternal ISI and EPDS, as well as between maternal ISI and child sleep variables (nighttime wakefulness and perceived child's sleep problems), after controlling for child age. Significant correlations were also found between maternal EPDS and child sleep, after controlling for child age, but these correlations were not significant once controlling for ISI. Cross-cultural differences in prevalence of insomnia and depressive symptoms were found based on the clinical cutoffs of the ISI and EPDS: Arab mothers, compared to Jewish mothers, reported higher levels of insomnia and depressive symptoms, and were more likely to have scores higher than the clinical cutoff on both measures.

CONCLUSION

Maternal insomnia, depressive symptoms, and child sleep quality are significantly intertwined in both Arab and Jewish families in Israel. The findings highlight the importance of taking these three domains into consideration in research and in clinical assessments of families with young children.

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.

Co-Rooming Accounts for Socioeconomic Disparities in Infant Sleep Quality among Families Living in Urban Environments

Poor infant sleep quality is associated with negative maternal and infant health outcomes. This study measures socioeconomic disparities in infant sleep quality, and assesses whether child sleep location and maternal stress mediate associations between socioeconomic status (SES) and infant sleep quality. The study includes 86 socioeconomically diverse, mother-infant dyads living in an urban area with infants aged 6–12 months. Mothers reported socioeconomic demographics, infant sleep quality (Brief Infant Sleep Questionnaire) and maternal subjective stress (Perceived Stress Scale). Maternal objective stress was measured via hair cortisol concentration (HCC). The associations among SES, infant sleep quality, infant co-rooming, and maternal stress were assessed. Infants from families with lower income-to-needs (ITN) ratios had poorer infant sleep quality. The association between familial ITN and infant sleep quality was mediated by whether the child co-rooms with parents. Maternal perceived stress was independently associated with infant sleep quality, but HCC was not associated with infant sleep quality.

Sleep patterns and intraindividual sleep variability in mothers and fathers at 6 months postpartum: a population-based, cross-sectional study

OBJECTIVES

Given that postpartum sleep is an important family process, further investigations including both mothers and fathers are necessary. The present study aimed to describe and compare sleep patterns and intraindividual night-to-night variability in mothers and fathers at 6 months postpartum using subjective and objective sleep measures.

DESIGN

Cross-sectional study.

SETTING

General community-based study in Montreal, QC, Canada.

PARTICIPANTS

Thirty-three couples (mothers and fathers) with no self-reported history of medical and mental health conditions participated in this study.

RESULTS

Parental sleep was measured across 10 consecutive nights using both a daily sleep diary and actigraphy. Results demonstrated that mothers' subjective and objective sleep was more fragmented compared with fathers (shorter longest consecutive sleep duration and more nocturnal awakenings; p<0.001). While mothers and fathers did not differ in their self-reported nocturnal sleep duration (p>0.05), actigraphy indicated that mothers obtained significantly longer nocturnal sleep duration (448.07 min±36.49 min) than fathers (400.96 min±45.42 min; p<0.001). Intraindividual sleep variability was revealed by relatively high coefficients of variation for parents across both subjective and objective indices related to sleep fragmentation (between 0.25 and 1.32). Actigraphy also demonstrated variability by mothers sleeping 6 hours consecutively on less than 3 nights, 27.27% (±22.81), and fathers on less than 6 nights, 57.27% (±24.53), out of 10. Associations were also found between parental sleep and family factors, such as age and infant sleep location (p<0.05).

CONCLUSIONS

These findings advance our knowledge of how sleep unfolds within the family system beyond the early postpartum weeks and/or months. Given the link between disturbed sleep and family functioning, the current research accentuates the importance of examining postpartum sleep patterns and variability in parents.

Neuronal gating of tactile input and sleep in 10-month-old infants at typical and elevated likelihood for autism spectrum disorder

Sleep problems in Autism Spectrum Disorder (ASD) emerge early in development, yet the origin remains unclear. Here, we characterise developmental trajectories in sleep onset latency (SOL) and night awakenings in infants at elevated likelihood (EL) for ASD (who have an older sibling with ASD) and infants at typical likelihood (TL) for ASD. Further, we test whether the ability to gate tactile input, using an EEG tactile suppression index (TSI), associates with variation in SOL and night awakenings. Parent-reported night awakenings and SOL from 124 infants (97 at EL for ASD) at 5, 10 and 14 months were analyzed using generalized estimating equations. Compared to TL infants, infants at EL had significantly more awakenings and longer SOL at 10 and 14 months. The TSI predicted SOL concurrently at 10 months, independent of ASD likelihood status, but not longitudinally at 14 months. The TSI did not predict night awakenings concurrently or longitudinally. These results imply that infants at EL for ASD wake up more frequently during the night and take longer to fall asleep from 10 months of age. At 10 months, sensory gating predicts SOL, but not night awakenings, suggesting sensory gating differentially affects neural mechanisms of sleep initiation and maintenance.

Parent ADHD Is Associated With Greater Parenting Distress in the First Year Postpartum

OBJECTIVE

Little is known about the experience of parenting infants when a mother or father has ADHD. This study examined cross-sectional predictors of parenting distress experienced by parents with and without ADHD who also have infants.

METHODS

Participants were 73 mother-father pairs (N = 146) of infants 6 to 10 months old. Half of the families included a parent with ADHD. Psychosocial predictors were tested using multilevel modeling.

RESULTS

Parent or partner ADHD, lower parent sleep quality, fewer social supports, and less infant surgency and effortful control were associated with greater parental distress. Infant negative affect and sleep were not associated.

CONCLUSIONS

Parents with ADHD and their partners experience greater parenting distress in the first year of their child's life than parents without ADHD. Addressing parent ADHD symptoms and co-occurring difficulties, including sleep disturbances, are potential targets for early interventions to maximize both parent and infant mental health outcomes.

Socioeconomic status and infant nighttime sleep across the second year of life: The moderating role of infant attachment security

This study examined socioeconomic status (SES) and attachment security as predictors of infant nighttime sleep during the second year. Participants included 128 mothers (86% White) with infants (48.4% boys). Data collection took place between April, 2009 and February, 2014. At 12, 18, and 24 months, infant sleep was assessed via actigraphy and daily diaries, and attachment with the Attachment Q-Set. SES indicators included income-to-needs ratios and education. Lower SES predicted greater variability in sleep duration and later sleep timing only for less secure infants. Less secure attachment was associated with poorer sleep at both between- and within-person levels, especially when infants were 12 months of age. Results emphasize the complex interactive effects of environmental and relational factors on infant sleep.

Effectiveness of behavioral sleep interventions on children's and mothers' sleep quality and maternal depression: a systematic review and meta-analysis

This systematic review and meta-analysis was conducted to investigate the effectiveness of behavioral sleep interventions (BSIs) on the number of child night awakenings, and maternal sleep quality and depression. The search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) using PubMed, CINAHL, Cochrane, and EMBASE databases and retrieved studies published until April 2021. We calculated the odds ratios (ORs) and 95% confidence intervals (CIs) for child sleep problems, and the mean differences (MD) and 95% CI for the number of child night awakenings, and maternal sleep quality and depression. Ten studies of 1628 initial searched were included in the final analysis. Two of the 10 studies were divided into two subgroups by participants and intervention type; thus, 12 subgroups were included in the meta-analysis. BSIs significantly reduced child sleep problems (OR 0.51; 95% CI 0.37-0.69) and improved maternal sleep quality (MD - 1.30; 95% CI - 1.82 to - 0.77) in the intervention group. There were no significant differences in the number of child night awakenings and maternal depression between the two groups. More RCTs to examine the effect of BSIs considering children's age, duration of intervention, and outcome measuring time points are needed.

A 1-year longitudinal study of the stress, sleep, and parenting of mothers of toddlers

OBJECTIVES

The present study, building on cross-sectional research showing links between mothers' sleep, stress, and parenting, used a longitudinal design to consider (1) the temporal direction of links between mothers' sleep and stress, (2) whether mother sleep deficits predict change in parenting across time, and (3) whether mother sleep deficits mediate the inverse association between stress and positive parenting.

DESIGN

The study used repeated measures of stress, mother sleep, and positive parenting at toddler ages 30, 36, and 42 months.

SETTING

Data were collected at 2 sites, one in the Midwest and one in the East.

PARTICIPANTS

Four hundred thirteen mother-toddler pairs were followed. Mothers were mostly married, college educated, and middle class, but there was also considerable variability between families.

MEASUREMENTS

Stress was measured via parenting hassles, CHAOS, and role overload scales. Mother sleep was measured via actigraphy. Positive parenting was observed during the bedtime routine and rated using the HOME scale and other items.

RESULTS

Mother stress and sleep were inextricably linked across toddlerhood, and worse sleep was predictive of less observed positive parenting, even when controlling for prior levels of stress and parenting.

CONCLUSIONS

Improving mothers' sleep may be important in efforts to improve their parenting.

Child Sleep Problems Affect Mothers and Fathers Differently: How Infant and Young Child Sleep Affects Paternal and Maternal Sleep Quality, Emotion Regulation, and Sleep-Related Cognitions

PURPOSE

Problems in infant and young child sleep can represent a serious challenge to parental behavior of mother and father. 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.

Lost in translation-the influence of language on infant sleep research

OBJECTIVES

We consider whether language shapes cultural interpretations of sleep in the family context using ethnographic data from the Czech Republic to explore one of the methods employed by Czech parents in helping their children aged 0-3 years to fall asleep.

METHODS

Multi-methodological ethnographic data were collected in the Czech Republic during 2015-2018 with supplemental online data obtained in 2020. This involved focus groups with 90 participants in mother-baby centers, and interviews with 30 families, supplemented with 468 online responses.

RESULTS

In the Czech Republic the use of parental presence with or without physical contact to help a child to fall asleep is a widespread practice. It is well-embedded within Czech culture and referred to by a widely known term: Uspávání. Parents expressed multiple motivations for using Uspávání to help their child sleep.

DISCUSSION

Within much of the Anglophone sleep literature the practice of actively helping a child to fall asleep is perceived as problematic. A child who cannot fall asleep alone is considered to exhibit "behavioral insomnia of childhood," and parents are advised to prevent this "sleep problem" by promoting self-soothing techniques in infancy. We suggest that as there is no English-language equivalent for the word Uspávání the concept it encapsulates is under-valued by sleep researchers, and the practice and its consequences are insufficiently researched.

CONCLUSIONS

Some important variations in parental sleep practices that are embedded in everyday family systems lack English terminology; Uspávání is one such example. This may lead to researchers overlooking or rejecting the validity of such diverse family sleep practices. There is a need for more ethnographic research of sleep in the context of different cultural environments and family systems to explore how language constrains understanding of parent-child sleep.

The Interaction between Lockdown-Specific Conditions and Family-Specific Variables Explains the Presence of Child Insomnia during COVID-19: A Key Response to the Current Debate

It is still debated whether lockdown conditions in response to the coronavirus disease 2019 (COVID-19) health crisis seriously affected children’s sleep. For young children, some studies identified more insomnia, while others only transient disturbances, or even no effect. Based on the premise of mother–child synchrony, a well-known dynamic established in child development research, we hypothesized that principally, the children whose mothers perceived the lockdown as stressful and/or responded maladaptively, suffered sleep disturbances. The main objective of this study was to identify the family profiles, variables, and lockdown responses most linked to insomnia in young children. The sample consisted of 165 mothers, French vs. Swiss origin (accounting for different lockdown severities), of children 6 months to 5 years old. Validated sleep, stress, and behavior scales were used. Multiple regression, age-matched clustering, and structural equation modeling analyses provided evidence that insomnia in young children is indeed strongly linked to the mother’s reaction to the pandemic and lockdown. Specifically, reactions such as COVID-19 fear/anxiety and obsessive COVID-19 information seeking coincide with heightened vigilance, cascading into reduced child social contact, outings, and increased screen viewing, ultimately culminating in child insomnia and behavioral problems. Mother education level and child day care quality (e.g., home-schooling) were also identified as strong insomnia predictors.

A photo-elicitation exploration of UK mothers' experiences of extended breastfeeding

In this qualitative study we explored the experiences of women breastfeeding children over 12 months of age. Data were collected from 24 participants using semi-structured photo-elicitation interviews and photo-prompted online surveys. Participants took photographs of their extended breastfeeding experiences over one week and reflected on how the events depicted made them feel, and what they represented in terms of their experience. Data were analysed using Interpretative Phenomenological Analysis. Four themes were developed; parenting through breastfeeding: meeting the needs of my child, my body is not my own, social influences on the breastfeeding experience, and thinking about stopping: my choice or theirs? Findings highlight that extended breastfeeding was experienced as beneficial for both mother and child, promoting closeness, and bonding, and providing a valued parenting tool. However, some mothers reported conflict between their desire for child-led extended breastfeeding and the need to regain autonomy and control of their own bodies. The dangers of negative societal responses to extended breastfeeding and risks to mental health posed by cultural constructions of 'ideal' motherhood are discussed.

Children's sleep and fathers' health and wellbeing: A systematic review

Night-waking is typical across infancy and early childhood, inevitably disrupting family sleep. For some children, sleep problems develop and endure throughout childhood. This systematic review focused on fathers, and synthesised the evidence pertaining to the effects of children's sleep (from birth to 12 years) on fathers' health and wellbeing. A total of 29 studies were included. Key outcomes reported for fathers were: sleep and fatigue; mental and general health; and family functioning. An association between child sleep and father's sleep was observed when child's sleep was measured via actigraphy or paternal report, but not when measured via maternal report, suggesting that mothers may not always be aware of disruptions that awaken fathers. Findings showed poorer child sleep was associated with poorer general health and wellbeing among fathers, however, associations of poor child sleep with depression were fewer, and less frequent than those reported for mothers in the same households. Poor child sleep was negatively associated with the quality of family relationships, both within the couple and between parent and child. Future studies seeking to understand the interplay of child sleep and family wellbeing should apply objective measurement of sleep and integrate formal measures of family dynamics into the study design.

A longitudinal study of the links between maternal and infant nocturnal wakefulness

STUDY OBJECTIVES

To examine the longitudinal links between maternal and infant nocturnal wakefulness by employing a trajectory-based approach, and to assess whether the strength of these links differs as a function of sleep assessment method (actigraphy vs. self-report) and sleeping arrangements.

METHODS

Maternal and infant nocturnal wakefulness were assessed with actigraphy and sleep diaries at home for 5 nights, at 3 (N = 191), 6 (N = 178), 12 (N = 155), and 18 (N = 135) months postpartum. Outcome measures included the number of night-wakings (NW) and the length of nocturnal wakefulness (WASO).

RESULTS

Strong associations between maternal and infant nocturnal wakefulness (controlling for nighttime breastfeeding) were found for NW and WASO. Trajectory analyses demonstrated that the strength of these relations decreased linearly from 3 to 18 months. Furthermore, the findings showed that the links between maternal and infant NW and WASO were stronger for maternal reports than for actigraphy. No consistent differences were found in the strength of the relations between maternal and infant NW and WASO as a function of sleeping arrangements (ie, room-sharing vs. solitary-sleeping families).

CONCLUSIONS

The results suggest that infant and maternal sleep are strongly intertwined, especially during the first 6 months. The decline in the synchronization between maternal and infant nocturnal wakefulness through infant development may be attributed to the growing ability of infants to self-soothe during the night. The findings emphasize the need to study sleep within a family context.

Social-ecological considerations for the sleep health of rural mothers

Using a social-ecological framework, we identify social determinants that interact to influence sleep health, identify gaps in the literature, and make recommendations for targeting sleep health in rural mothers. Rural mothers experience unique challenges and protective factors in maintaining adequate sleep health during the postpartum and early maternal years. Geographic isolation, barriers to comprehensive behavioral medicine services, and intra-rural ethno-racial disparities are discussed at the societal (e.g., public policy), social (e.g., community) and individual levels (e.g., stress) of the social-ecological model. Research on sleep health would benefit from attention to methodological considerations of factors affecting rural mothers such as including parity in population-level analyses or applying community-based participatory research principles. Future sleep health programs would benefit from using existing social support networks to disseminate sleep health information, integrating behavioral health services into clinical care frameworks, and tailoring culturally-appropriate Telehealth/mHealth programs to enhance the sleep health of rural mothers.

The Relationship between Fatigue in Mothers and the Age of Their Less-Than-24-Month-Old Newborns

The birth of a child marks the beginning of a new developmental period for the parents. These changes have positive but also negative aspects, such as the increase in fatigue experienced by mothers during this period of time, which can be very limiting and lead them to postpone other life or work goals. However, despite the widespread nature of this problem, there is a lack of information about the duration of this fatigue, with estimates ranging from three months to six years; this prevents mothers from planning this period of their lives adequately. The current study evaluated fatigue in a Spanish sample of 67 women with infants less than two years old and drew a comparison with another sample of 46 women with similar characteristics who were not caring for an infant at that time in order to determine the differences between them and how fatigue in the former group evolves depending on the age of the infant. The results show that fatigue is effectively maintained until at least two years after the birth of the infant.

Parents matter: barriers and solutions when implementing behavioural sleep interventions for infant sleep problems

Behavioural sleep interventions (eg, extinction-based methods) are among the most efficacious evidence-based techniques in the treatment of infant sleep problems. However, behavioural sleep interventions can be challenging for families to successfully implement. This review aims to summarise current research surrounding the potential barriers that arise when clinicians attempt to implement extinction-based methods with parents of infants. We provide a model that summarises 3 types of contextual-barriers; socio-cultural barriers, parent barriers, and infant barriers. Based on the current evidence, we propose that adopting a stepped care approach, planning ahead, increasing support, motivational interviewing, and/or emotional regulation may serve as useful tools for parents when implementing extinction-based methods. By considering these techniques, more families may receive the benefits of improved infant sleep.

A mixed methods study of perinatal sleep and breastfeeding outcomes in women at risk for postpartum depression

INTRODUCTION

Pregnant and postpartum women experience significant sleep disruption, but the role of perinatal sleep disturbances in breastfeeding is understudied.

METHODS

In this observational cohort study, we used mixed methods to examine associations between perinatal sleep and breastfeeding. Forty-eight women (mean age 28.2 ± 4.9 years) who were euthymic at enrollment but had a history of major depression (n = 43) or bipolar disorder (n = 5) had sleep recorded with wrist actigraphy. We determined feeding status through daily diaries and used semi-structured interviews to identify themes regarding participants' experiences, breastfeeding decisions, and behaviors. To examine whether sleep disturbance during pregnancy predicted breastfeeding (BF) rates, we defined "lower sleep efficiency" (LSE) and "higher sleep efficiency" (HSE) groups based on the median split of actigraphic SE at 33 weeks' gestation (cutoff SE = 84.9%) and classified mothers as No-BF, Mixed-BF (BF + formula), and Exclusive-BF at 2 weeks postpartum.

RESULTS

Percentages of women who did any breastfeeding were: Week 2 = 72.3%, Week 6 = 62.5%, Week 16 = 50%. LSE mothers were less likely than HSE mothers to initiate breastfeeding (percent No-BF: LSE = 45.8%, HSE = 16.7%, P < .05). Average actigraphic sleep onset, sleep offset, time in bed, sleep duration, and SE did not differ based on breastfeeding status at any time point. Qualitative themes included insufficient preparation for the demands of breastfeeding, interrupted and nonrestorative sleep, and unrelenting daytime tiredness.

CONCLUSIONS

In our sample, preserved actigraphic SE during pregnancy was associated with initiation and continuation of breastfeeding. Future work should examine whether improving sleep in pregnancy improves mothers' feeding experiences.

Parents' Perceptions of Infants' Nighttime Sleep Patterns Predict Mothers' Negativity: A Longitudinal Study

OBJECTIVE

Infants' sleeping patterns can influence parents' sleep and their well-being. Infants' sleeping problems can evoke negative emotions from their parents because of the influence the problems have on parents' lives. However, little is known regarding the associations between infants' night sleep patterns and parents' overall negativity toward their children. The objective of this study was to study this association.

METHODS

In a longitudinal design, we followed infants and their parents from 9 to 18 months. Overall, 392 families participated in the study. Parents' negativity and children's sleeping patterns were assessed with questionnaires.

RESULTS

Parents' negativity and children's sleeping problems showed moderate continuity through the study's 9-month period. Children's sleeping problems at 9 months predicted an increase in mothers' (but not fathers') negativity at 18 months. Parents' negativity was not associated with infants' sleep problems.

CONCLUSION

The results of this study suggest that already in infancy, children's tendencies, in this case sleep, can evoke negative emotions in their mothers and highlight infants' roles in the intricate parent-child relationship.

Sensing everyday activity: Parent perceptions and feasibility

Mobile and wearable sensors provide a unique opportunity to capture the daily activities and interactions that shape developmental trajectories, with potential to revolutionize the study of development (de Barbaro, 2019). However, developmental research employing sensors is still in its infancy, and parents' comfort using these devices is uncertain. This exploratory report assesses parent willingness to participate in sensor studies via a nationally representative survey (N = 210) and live recruitment of a low-income, minority population for an ongoing study (N = 359). The survey allowed us to assess how protocol design influences acceptability, including various options for devices and datastream resolution, conditions of data sharing, and feedback. By contrast, our recruitment data provided insight into parents' true willingness to participate in a sensor study, with a protocol including 72 h of continuous audio, motion, and physiological data. Our results indicate that parents are relatively conservative when considering participation in sensing studies. However, nearly 41 % of surveyed parents reported that they would be at least somewhat willing to participate in studies with audio or video recordings, 26 % were willing or extremely willing, and 14 % reported being extremely willing. These results roughly paralleled our recruitment results, where 58 % of parents indicated interest, 29 % of parents scheduled to participate, and 10 % ultimately participated. Additionally, 70 % of caregivers stated their reason for not participating in the study was due to barriers unrelated to sensing while about 25 % noted barriers due to either privacy concerns or the physical sensors themselves. Parents' willingness to collect sensitive datastreams increased if data stayed within the household for individual use only, are shared anonymously with researchers, or if parents receive feedback from devices. Overall, our findings suggest that given the correct circumstances, mobile sensors are a feasible and promising tool for characterizing children's daily interactions and their role in development.

Do Mothers Have Worse Sleep Than Fathers? Sleep Imbalance, Parental Stress, and Relationship Satisfaction in Working Parents

PURPOSE

Previous research indicates that mothers take a larger responsibility for child care during the night and that they have more disturbed sleep than fathers. The purpose of this study was to determine whether such a sleep imbalance exists in working parents of young children, and the extent to which it depends on the way sleep is measured. The study also examined whether imbalanced sleep between parents predicts parental stress and relationship satisfaction.

METHODS

Sleep was measured for seven consecutive days in 60 parenting couples (average age of the youngest child: 3.3 years ± SD 2.5 years). Actigraphs were worn across the week, and ratings of sleep, parental stress, and relationship satisfaction were made daily.

RESULTS

Mothers perceived their sleep quality as worse (b= -0.38 scale units, p<0.001), with more wake periods (b= +0.96 awakenings, p<0.001) but with longer sleep duration (b= +32.4 min, p<0.01) than fathers. Actigraphy data confirmed that mothers slept longer than fathers (b= +28.03 min, p<0.001), but no significant differences were found for wake time, number of awakenings or who woke up first during shared awakenings. Furthermore, there was no difference in whether mothers and fathers slept sufficiently. The level of sleep imbalance between parents did not predict parental stress. A larger imbalance in subjective sleep sufficiency predicted decreased relationship satisfaction for fathers (b= -0.13 scale units, p<0.01) but increased relationship satisfaction for mothers (b= 0.14 scale units, p<0.05). No other sleep imbalance measures predicted relationship satisfaction.

CONCLUSION

Our findings are in line with previous research on sleep in men and women in general, with longer sleep and subjective reports of sleep disturbances in women, rather than previous research on sleep in parents of young children. Thus, we found no evidence of a sleep imbalance when both parents have similar working responsibilities.

Longitudinal correlates of sleep duration in young children

OBJECTIVE

The primary aim of this study was to longitudinally examine potential demographic and screen time correlates of nap duration, nighttime sleep duration, and total sleep duration in young children over two time points.

METHODS

Data from the supporting Healthy physical AcTive Childcare setting (HATCH) study were analyzed. Participants were 206 toddlers (19-35 months) and preschoolers (36-60 months) in Alberta and Ontario, Canada. Child age, screen time (television, video games), and sleep duration (nap, nighttime) were measured at baseline and six-month follow-up, while other demographic variables were assessed at baseline only using the HATCH parental questionnaire. Mixed models were performed to examine the associations between potential correlates and sleep duration over time.

RESULTS

In the multiple regression models, significant correlates of total sleep duration (min/d) were child age (months; B = -3.03; 95%CI:-3.88,-2.19) and parental education (bachelor's degree vs. below bachelor level; B = 29.74, 95%CI:7.43,52.06). Significant correlates of nighttime sleep duration (min/d) included child age (B = -0.81; 95CI%:-1.53,-0.10), child race/ethnicity (Caucasian vs. non-Caucasian; B = 15.31; 95%CI:0.38,30.25), household income (>$150,000 vs. <$50,000; B = 32.93, 95%CI:9.80,56.06), television time (B = -0.19, 95%CI:-0.32,-0.05), video games time (B = -0.19, 95%CI: -0.38, -0.01) and total screen time (B = -0.19; 95%CI:-0.29,-0.08). Significant correlates of nap duration (min/d) were child age (B = -2.10; 95%CI:-2.68,-1.51) and race/ethnicity (Caucasian vs. non-Caucasian; B = -13.73; 95%CI:-25.78,-1.68).

CONCLUSION

Young children who were non-Caucasian, from lower income families, who had less-educated parents, or who had more screen time tended to have shorter sleep duration. Targeting these demographic groups and screen time appears important for promoting adequate sleep duration in early childhood.

Insomnia and poor sleep quality during peripartum: a family issue with potential long term consequences on mental health

BACKGROUND

Improving maternal's health is a worldwide priority. Sleep is a fundamental operating state of the central nervous system and it may be one of the most important psychophysiological processes for brain function and mental health. The study of maternal sleep problem including insomnia, however, implies deepening our understanding of family context. Family systems are dynamic and involve reciprocal interactions among members during day and night. So far, however, maternal and children's sleep has been rarely studied in a family perspective, and paternal sleep has often been neglected.

METHODS

The present work summarizes in a narrative review the state of the art of our current knowledge on the role of insomnia and poor quality of sleep for mental health in all family members in the peripartum period. The mother, the father, the child and the family interactive perspectives are considered.

RESULTS

Insomnia and poor sleep problems are frequent in all family members during peripartum. Poor sleep and insomnia symptoms are recognized as important risk factors for mental health in adults and children. Despite this alarming evidence, sleep is rarely assessed in clinical contexts.

CONCLUSIONS

Clinical implications include the utmost relevance of assessing sleep problems during pregnancy and early post-partum. Insomnia and poor sleep quality should be evaluated and treated in the clinical practice by using a "family perspective."

Fathers and Sleep: A Systematic Literature Review of Bidirectional Links Between Paternal Factors and Children's Sleep in the First Three Years of Life

Objective

During childhood, sleep problems are a common concern for parents and families. The literature on children’s sleep documents a strong association between parental factors and infant sleep quality. However, most studies have only examined maternal attitudes and behaviors. To systematically identify and assess the existing literature on the role of fathers in children’s sleep over the first three years of life.

Method

Studies were identified from January 1993 to July 2020 in four electronic databases, following PRIMSA guidelines.

Results

The initial search yielded a total of 657 records. Fifty-nine studies were full review, and 26 studies met all inclusion criteria and formed the basis for the review. Studies were divided into thematic groups as a function of the paternal variables they investigated: Extrinsic Parenting factors, Parent-child Interaction Context, and Distal Environmental Influences.

Conclusions

This review points up a range of paternal variables that can represent risk or protective factors for child sleep. Our results may help parents and healthcare practitioners to identify evidence-based knowledge about sleep. Furthermore, identifying paternal factors that contribute to sleep problems can usefully inform the design of individualized interventions.

Parenting stress during infancy is a risk factor for mental health problems in 3-year-old children

BACKGROUND

Although research on the relationship between parent and child mental health is growing, the impact of early parenting stress on preschool-aged children's mental health remains unclear. The objective was to evaluate the association between parenting stress during infancy and mental health problems in 3-year-old children.

METHODS

A prospective cohort study of healthy preschool-aged children recruited from 9 primary care practices in Toronto, Canada was conducted through the TARGet Kids! primary care practice-based research network. Parenting stress was measured when children were between 0 to 16 months of age, using the Parent Stress Index Short Form, PSI-SF. Parent-reported child mental health problems were measured at 36 to 47 months using the preschool Strengths and Difficulties Questionnaire, total difficulties score (TDS). Hierarchical linear regression analysis was used to investigate the association between standardized PSI-SF and TDS, adjusted for child age, sex, temperament, sleep duration and household income. To strengthen clinical interpretation, analysis was repeated using adjusted multivariable logistic regression (TDS dichotomized at top 20%).

RESULTS

A total of 148 children (mean ± SD age, 37.2 ± 1.7 months, 49% male) were included in the analysis. Parenting stress during infancy (11.4 ± 3.1 months of age) was significantly associated with mental health problems in 3-year-old children (β = 0.35; 95% CI = 0.20-0.49, p < 0.001). Higher parenting stress was also associated with increased odds of higher TDS (OR = 2.26, 95% CI = 1.69-2.83, p < 0.01).

CONCLUSION

Healthy preschool-aged children with parents reporting parenting stress during infancy had a 2 times higher odds of mental health problems at 3 years.

Parental Involvement in Children's Sleep Care and Nocturnal Awakenings in Infants and Toddlers

Background: Sleep regulation and consolidation represent critical developmental processes that occur in the first years of life. Recent studies have highlighted the contribution of caregivers to sleep development. However, the majority of them have primarily focused on maternal behaviors, overlooking fathers. The main goal of the present study was to investigate the associations between paternal and maternal involvement in children’s sleep care and the number of night awakenings reported by both parents in infants and toddlers. Methods: One-hundred-and-one families of infants aged 8 to 12 months and 54 families of toddlers aged 18 to 36 months filled out the following self-report questionnaires: The Brief Infant Sleep Questionnaire and an ad hoc questionnaire to assess parental involvement in sleep care for children. A moderate actor–partner interdependence (APIM) with path analysis was performed to test the predictive role of parental involvement on the children’s sleep (no. of nocturnal awakenings) and the moderation role of age on these relationships. Results: Paternal involvement in children’s sleep care was associated with the number of night awakenings reported by both parents. Moreover, a significant interaction effect emerged between the children’s age and paternal involvement in children’s sleep care for predicting nocturnal awakenings. Conclusions: The main outcomes of this study point to the protective role of paternal involvement in children’s sleep during the first years of life.

Effectiveness of an mHealth Intervention for Infant Sleep Disturbances

Bedtime problems and night wakings are highly prevalent in infants. This study assessed the real-world effectiveness of an mHealth behavioral sleep intervention (Customized Sleep Profile; CSP). Caregivers (83.9% mothers) of 404 infants (age 6 to 11.9 m, M = 8.32 m, 51.2% male) used the CSP (free and publicly available behavioral sleep intervention delivered via smartphone application, Johnson's® Bedtime® Baby Sleep App). Caregivers completed the Brief Infant Sleep Questionnaire-Revised (BISQ-R) at baseline and again 4 to 28 days later. Changes in sleep patterns were analyzed, based on sleep problem status (problem versus no problem sleepers; PS; NPS). Sleep onset latency improved in both groups. Earlier bedtimes, longer continuous stretches of sleep, as well as decreased number and duration of night wakings, were evident in the PS group only. The BISQ-R Total score, total nighttime sleep, and total 24-hour sleep time improved for both groups, with a greater change for the PS group. Further, caregivers of infants in the PS group decreased feeding (bedtime and overnight) and picking up overnight, and perceived better sleep. Bedtime routine regularity, bedtime difficulty, sleep onset difficulty, and caregiver confidence improved for both groups, with the PS group showing a greater magnitude of change. Thus, a real-world, publicly available, mHealth behavioral sleep intervention was associated with improved outcomes for older infants. Intervention recommendations resulted in changes in caregivers' behavior and improvements in caregiver-reported sleep outcomes in infants, in as few as 4 days.

Predictive Factors of Toddlers' Sleep and Parental Stress

Background: Although most infants consolidate their sleep habits during the first year of life, for many children, sleep is described as disrupted during toddlerhood. Along with individual child variables such as temperamental characteristics, parenting behaviors play a key role in determining children’s sleep–wake patterns. The aims of the current study were to evaluate the relationship among toddlers’ sleep quality, emotion regulation, bedtime routines, parental bedtime involvement, parental perceived social support and stress, and to integrate a novel combination of the aforementioned dimensions into predictive models of toddlers’ sleep quality and parental stress. Methods: One hundred and sixty parents with 2–3-year-old children filled out the following self-report questionnaires: the Parent–Child Sleep Interaction Scale; the Emotion Regulation Checklist; the Social Provisions Scale; and an ad-hoc questionnaire to assess parental involvement in everyday and bedtime care for children. Three multiple regression analyses were conducted by regressing maternal and paternal parenting stress and infant’s quality sleep onto the independent variables described above. Results: Toddlers’ emotion regulation and parental psychosocial functioning were related to parental stress. Toddlers’ night awakenings and the time required by toddlers to fall asleep were related to parental distress. Conclusions: The findings evidenced the bidirectional associations among the studied variables, highlighting the protective role of social support in reducing parenting stress and of paternal bedtime involvement in improving toddlers’ sleep quality.

Postnatal trajectories of maternal depressive symptoms: Postpartum antecedents and differences in toddler adjustment

Infants are uniquely vulnerable to maternal depression's noxious effects, but few longitudinal studies have tried to identify discrete postnatal trajectories of maternal depressive symptoms (MDS) beginning in infancy. This study extends evidence of heterogeneous change in postnatal MDS by examining their cross-contextual antecedents in infancy and their consequences for children's early behavior problems and language skills in late toddlerhood. A community sample of mother-child dyads (N = 235, 72% Caucasian) was assessed when children were 7, 15, and 33 months old. Mothers reported their socioeconomic status (SES), social support, marital relationship quality, family dysfunction, parenting stress, and infants' functional regulatory problems at 7 months postpartum, and children's internalizing and externalizing symptoms at 33 months. Children completed a receptive vocabulary assessment at 33 months in the lab. Latent class growth analysis identified three postnatal MDS trajectory classes that fit the data best: low-decreasing, moderate, and increasing. Psychosocial measures at seven months postpartum primarily predicted membership to these postnatal trajectory classes, which subsequently differed in children's internalizing, externalizing, and receptive vocabulary in late toddlerhood, controlling for family SES and functional regulatory problems in infancy. We discuss salient antecedents and consequences of postnatal depression for mothers and their offspring.

Temporal Patterns of Infant Regulatory Behaviors in Relation to Maternal Mood and Soothing Strategies

This study investigates the temporal patterning of infant self-regulatory behaviors (crying/fussing, sleeping) in relation to both infant (age, sex, regulatory problems) and maternal variables (soothing behaviors, mood). Self-regulatory and soothing behaviors were assessed in 121 mother-infant dyads (4-44 weeks) by the Baby's Day Diary at 5 min intervals over 3 days. Further infant characteristics and maternal mood were assessed by questionnaires (DASS, CES-D, STAI) and the Diagnostic Interview for the Assessment of Regulatory Problems in Infancy and Toddlerhood. Data were analyzed using generalized additive mixed models. Negative maternal mood was associated with a deviant course of crying/fussing during the day. Body contact was associated with reduced variability in the 24 h course of sleep. Mother-infant transactional processes-above and beyond known relationships with overall levels of crying/fussing and sleeping-might play out on the temporal dimension of infant regulatory behaviors.

Mothers' postpartum sleep disturbance is associated with the ability to sustain sensitivity toward infants

BACKGROUND/OBJECTIVE

Infancy is a period of rapid development when the quality of caregiving behavior may be particularly consequential for children's long-term functioning. During this critical period for caregiving behavior, parents experience changes in their sleep that may affect their ability to provide sensitive care. The current study investigated the association of mothers' sleep disturbance with both levels and trajectories of maternal sensitivity during interactions with their infants.

METHODS

At 18 weeks postpartum, mothers and their infants were observed during a home-based 10-minute "free play" interaction. Mothers' nighttime sleep was objectively measured using actigraphy and subjectively measured using sleep diaries. Maternal sensitivity was coded in two-minute intervals in order to characterize changes in sensitivity across the free play interaction. We used exploratory factor analysis to reduce the dimensionality of the objective and subjective measures of mothers' sleep, identifying a subjective sleep disturbance and an objective sleep continuity factor.

RESULTS

Using multi-level modeling, we found that mothers with poorer objective sleep continuity evidenced decreasing sensitivity toward their infants across the interaction. Mothers' self-reports of sleep disturbance were not associated with maternal sensitivity.

CONCLUSIONS

Although future research is necessary to identify the mechanisms that may explain the observed association between poor sleep continuity and the inability to sustain sensitivity toward infants, mothers' postpartum sleep continuity may be one factor to consider when designing interventions to improve the quality of caregiving.

Maternal stress, sleep, and parenting

Associations between stress, sleep, and functioning have been well-established in the general adult population, but not as well-established in the specific subpopulation of interest here-parents. To advance understanding of how maternal sleep is linked with both mothers' experiences of stress and their parenting, this study used actigraphic and mother-report measures of sleep, observed and mother reports of parenting, and measures of multiple stressors of relevance. In a community sample of mothers of toddlers (N = 314; child age M = 2.60, SD = 0.07 years), maternal stress was indexed with a cumulative risk score that combined sociodemographic risks and common parent stressors, including household chaos, role overload, parenting hassles, child misbehavior, negative life events, and lack of social support. We found that mothers who experienced shorter, later, and more variable sleep experienced higher levels of stress as indexed by the cumulative risk index. In addition, those with higher stress required longer to fall asleep and perceived more sleep problems. We also found that actigraphic measures of poor and insufficient maternal sleep were associated with less observed positive parenting, even when controlling for the cumulative risk index and maternal age, employment, and family size. Mothers who required longer to fall asleep also reported more dysfunctional parenting, with the same statistical controls. The findings, coupled with research showing that sleep is amenable to intervention, suggest that parental sleep may ultimately prove to be a useful intervention target for promoting positive parent involvement and responsiveness.

A Proposed Nursing Theory: Infant Sleep and Development

Although well positioned to work with families of young children, nurses do not yet have a theory that guides practice and research by relating infant sleep to child and family development. The authors of this paper describe a proposed theory that combines Bronfenbrenner's bioecological theory of human development with the Barnard model of parent-child interaction to inform nursing practice and research related to infant sleep and optimizing child and family development. The theory focuses on sustainability of change in family processes and infant sleep, with a goal of optimizing family wellness as the proximal environment for child development.

IGNORING CHILDREN'S BEDTIME CRYING: THE POWER OF WESTERN-ORIENTED BELIEFS

Ignoring children's bedtime crying (ICBC) is an issue that polarizes parents as well as pediatricians. While most studies have focused on the effectiveness of sleep interventions, no study has yet questioned which parents use ICBC. Parents often find children's sleep difficulties to be very challenging, but factors such as the influence of Western approaches to infant care, stress, and sensitivity have not been analyzed in terms of ICBC. A sample of 586 parents completed a questionnaire to investigate the relationships between parental factors and the method of ICBC. Data were analyzed using structural equation modeling. Latent variables were used to measure parental stress (Parental Stress Scale; J.O. Berry & W.H. Jones, 1995), sensitivity (Situation-Reaction-Questionnaire; Y. Hänggi, K. Schweinberger, N. Gugger, & M. Perrez, 2010), Western-oriented parental beliefs (Rigidity), and children's temperament (Parenting Stress Index; H. Tröster & R.R. Abidin). ICBC was used by 32.6% (n = 191) of parents in this study. Parents' Western-oriented beliefs predicted ICBC. Attitudes such as feeding a child on a time schedule and not carrying it out to prevent dependence were associated with letting the child cry to fall asleep. Low-sensitivity parents as well as parents of children with a difficult temperament used ICBC more frequently. Path analysis shows that parental stress did not predict ICBC. The results suggest that ICBC has become part of Western childrearing tradition.
