Time for bed! Earlier sleep onset is associated with longer nighttime sleep duration during infancy

The sleep problems in individuals with Rett syndrome and their caregivers

LAY ABSTRACT

Sleep problems are common and impactful among individuals with Rett syndrome (RTT) and their caregivers. We examined the sleep patterns of 29 RTT patients and their primary caregivers using various assessment tools. The study found that a majority of the patients experienced sleep disturbances, with younger patients showing more sleep difficulties. Caregivers also reported poor sleep quality. The findings emphasize the need to address sleep problems in RTT management, as improving sleep quality can positively impact the well-being of individuals with RTT and their caregivers.

Racial/ethnic disparities in infant sleep in the COVID-19 Mother Baby Outcomes (COMBO) study

OBJECTIVE

Investigate racial and ethnic differences in infant sleep and examine associations with insurance status and parent-infant bedtime behavioral factors (PIBBF).

METHODS

Participants are part of the COVID-19 Mother Baby Outcomes (COMBO) Initiative, Columbia University. Data on infant sleep (night, day and overall sleep duration, night awakenings, latency, infant's sleep as a problem) were collected at 4 months postpartum. Regressions estimated associations between race/ethnicity, insurance status, PIBBF and infants' sleep.

RESULTS

A total of 296 infants were eligible (34.4% non-Hispanic White [NHW], 10.1% Black/African American [B/AA], 55.4% Hispanic). B/AA and Hispanic mothers were more likely to have Medicaid, bed/room-share, and report later infant bedtime compared to NHW mothers. Infants of B/AA mothers had longer sleep latency compared to NHW. Infants of Hispanic mothers slept less at night (∼70 ± 12 minutes) and more during the day (∼41 ± 12 minutes) and Hispanic mothers were less likely to consider infants' sleep as a problem compared to NHW (odds ratio 0.4; 95% confidence interval: 0.2-0.7). After adjustment for insurance status and PIBBF, differences by race/ethnicity for night and day sleep duration and perception of infant's sleep as a problem persisted (∼32 ± 14 minutes, 35 ± 15 minutes, and odds ratio 0.4; 95% confidence interval: 0.2-0.8 respectively). Later bedtime was associated with less sleep at night (∼21 ± 4 minutes) and overall (∼17 ± 5 minutes), and longer latency. Infants who did not fall asleep independently had longer sleep latency, and co-sleeping infants had more night awakenings.

CONCLUSIONS

Results show racial/ethnic differences in sleep in 4-month-old infants across sleep domains. The findings of our study suggest that PIBBF have an essential role in healthy infant sleep, but they may not be equitably experienced across racial/ethnic groups.

Infant sleep as a topic in healthcare guidance of parents, prenatally and the first 6 months after birth: a scoping review

Background

This scoping review focuses on infant sleep-related factors and themes that are relevant when health practitioners provide preventive health services to expectant and new parents.

Methods

A systematic literature search in CINAHL, PubMed, and PsycINFO, published in 2010 or later, identified 1661 records. The search was further narrowed to focus on sleep in healthy term-born infants until the second half of the first year of life. A blinded review by both authors covered 136 papers, of which 43 papers were reviewed in the full text. Finally, 38 articles were included in the data extraction.

Results

The analysis process showed that the selected studies formed three main information categories: 11 studies thematised safe infant sleep issues, 10 studies described design and findings from sleep-related intervention studies, and 17 studies focused on different parent-child interactive aspects that may influence the quality and duration of infant sleep in the first six months of life.

The main finding is that knowledge about early infant sleep is very complex, and includes both child, parent, and environmental factors. Several studies have shown that the concepts and factors related to safe infant sleep also influence the development of healthy infant sleep patterns. Thus, these aspects are interwoven with each other and should be addressed together in communication with parents.

Conclusions

Health practitioners with different professional backgrounds need to search for an agreement on when and how different aspects of sleep-related knowledge should be communicated to new and expectant parents to enable the design of national follow-up programs. Parents want coherent and personalized services regarding infant sleep issues that may allow them to choose sleeping arrangements, routines, and behaviors that fit in with their sociocultural attitudes and traditions. Many different sources and formats may be used to empower parents regarding infant sleep issues. Studies have described the use of group or individual meetings, videos, and written materials. The key issue is the importance of consistent and seamless knowledge-based services.

Family promotion of children's healthy lifestyles during the COVID-19 pandemic in light of Saudi Vision 2030

Objective

This study aims to determine the role of the family in promoting an active and healthy lifestyle for children aged 3-12 years during the COVID-19 pandemic in the Qassim region in light of Saudi Arabia's Vision 2030 program.

Background

This study is important in defining the role of the family in promoting an active lifestyle for children during the COVID-19 pandemic because the family is primarily responsible for promoting a healthy lifestyle for children.

Method

We evaluated responses of 320 parents completing an online survey about their children's physical health during the pandemic.

Results

The results showed a low level of children's physical activity and excessive use of electronic devices. Late bedtimes were evident and defined as midnight or later. As well, however, families knew the necessary information about COVID-19 and maintained the children's preventive measures. The families were aware of the child's consumption of a healthy diet. They helped the child complete studies through distance education. The families supported the child's psychological well-being and helped them develop some entertainment plans.

Conclusions

Although the family plays an important role in promoting the active and healthy lifestyle of the child, there is still a need for more awareness regarding the child's practice of physical activity, healthy sleep habits, and correct use of electronic devices.

Implications

Programs should be established to increase family awareness of the guidelines of the World Health Organization and the Saudi Ministry of Health regarding the child's physical activity, sleep habits, and the use of electronic devices.

Synchronizing Our Clocks as We Age: The Influence of the Brain-Gut-Immune Axis on the Sleep-Wake Cycle Across the Lifespan

The microbes that colonize the small and large intestines, known as the gut microbiome, play an integral role in optimal brain development and function. The gut microbiome is a vital component of the bi-directional communication pathway between the brain, immune system, and gut, also known as the brain-gut-immune axis. To date there has been minimal investigation into the implications of improper development of the gut microbiome and the brain-gut-immune axis on the sleep-wake cycle, particularly during sensitive periods of physical and neurological development, such as childhood, adolescence, and senescence. Therefore, this review will explore the current literature surrounding the overlapping developmental periods of the gut microbiome, brain, and immune system from birth through to senescence, while highlighting how the brain-gut-immune axis affects maturation and organisation of the sleep-wake cycle. We also examine how dysfunction to either the microbiome or the sleep-wake cycle negatively affects the bidirectional relationship between the brain and gut, and subsequently the overall health and functionality of this complex system. Additionally, this review integrates therapeutic studies to demonstrate when dietary manipulations, such as supplementation with probiotics and prebiotics, can modulate the gut microbiome to enhance health of the brain-gut-immune axis and optimize our sleep-wake cycle.

Association of Allergic Symptoms in the First 2 Years of Life With Sleep Outcomes Among Chinese Toddlers

Background: Previous studies have linked allergic symptoms to sleep in children, but the associations might be different when considering different types of allergic symptoms or sleep outcomes. Moreover, the combined effects of multiple allergic symptoms remain unclear in early life. This study aimed to investigate the associations between multiple allergic symptoms and sleep outcomes in early life. Methods: We included 673 toddlers aged 2 years from a birth cohort in Guangzhou, China. We identified allergic symptoms (skin, eyes and nose, gastrointestinal tract, mouth and lips, and wheeze) within 2 years via standard questionnaires. Sleep outcomes including sleep duration and quality over the past month were assessed based on the Chinese version of the Brief Infant Sleep Questionnaire. Associations between allergic symptoms and sleep outcomes were examined using multivariable linear regression and logistic regression. Results: Compared to children without allergic symptoms, children with allergic nasal and ocular symptoms had higher odds of frequent nighttime awakenings (OR = 1.41; 95% CI: 1.03, 1.93) and irregular sleep (OR = 1.45, 95% CI: 1.05, 2.00); children with allergic gastrointestinal symptoms slept 0.28 h less during nighttime (95% CI: -0.48, -0.07) and 0.25 h less per day (95% CI: -0.43, -0.08), and had 59% higher odds of irregular sleep (95% CI: 1.24, 2.04). We also found significant association of multiple allergic symptoms with shortened nighttime sleep duration and increased irregular sleep. Whereas, allergic skin, mouth and lips, and wheeze symptoms were not significantly associated with sleep outcomes. Conclusion: Allergic symptoms within 2 years of age were adversely associated with sleep outcomes, which highlight the importance of early screening of allergic symptoms in toddlers in order to improve their sleep outcomes.
