Neighborhood environments and sleep among children and adolescents: A systematic review

Long-term exposure to major constituents of fine particulate matter and sleep disorders among children and adolescents: A population-based survey in Guangdong province, China

Long-term exposure to PM2.5 is associated with sleep health in adults, but its impact on children and adolescents remains unclear. This cross-sectional study analyzed 64,203 children and adolescents (6-18 years) from four cities in Guangdong, China, to assess the impact of PM2.5 and its major constituents on sleep disorders. Sleep disorders were assessed using the Sleep Disturbance Scale for Children. Generalized linear mixed models and weighted quantile sum regression were applied to assess the joint effects of PM2.5 constituents. The results indicated a positive association between PM2.5 and sleep disorders. For example, the odds of sleep disorder increased with per interquartile range (IQR) increase in PM2.5 concentrations [odds ratio (OR): 1.15, 95 % confidence interval (CI):1.06, 1.26). Black carbon (BC) and organic matter (OM) increase the odds by 16 % (95 % CI: 9, 24 %) and 23 % (95 % CI: 9, 39 %), respectively. Notably, combustion-related BC (44.3 %) and OM (24.3 %) contributed the key contributors to the mixture risk. Children and adolescents with limited outdoor activity (< 2 hours/day) were more vulnerable to PM2.5 exposure (P for interaction = 0.028). These findings highlight that stricter air pollution regulations and targeted measures to reduce children's exposure to combustion-derived pollutants are essential for protecting sleep health and overall well-being.

Autism Spectrum Disorder and Health-Determining Behaviors: Assessing Physical Activity, Screen Time, and Sleep with the National Survey of Children's Health

To compare the national prevalence of meeting physical activity, screen time, and sleep guidelines between autistic and nonautistic children and identify factors associated with meeting these guidelines. Prevalences for each health-determining behavior were estimated using the 2022 National Survey of Children's Health, using national guidelines. Complex survey-weighted logistic regression, adjusted for demographic covariates, was used to measure associations between autism and meeting each guideline, and to identify potential child, family, community, and policy-level determinants of each behavior among autistic children. The prevalence of meeting all three guidelines was low among autistic and nonautistic children across age groups. Physical activity guidelines were met at similarly low rates among autistic and nonautistic children; however, autistic children of all age groups were less likely to meet screen time guidelines, and those in the 3-5 and 6-11 years age groups were less likely to meet sleep guidelines. Moderate/severe autism, irregular bedtime, low parental education, and lacking a medical home were associated with lower likelihood of meeting sleep guidelines. Irregular bedtime and high income were associated with lower likelihood of meeting physical activity guidelines. Autistic children meet guidelines for physical activity, screen time, and sleep at a low prevalence and less than their nonautistic peers. Clinicians should develop individualized plans to facilitate adherence to guidelines among autistic children. Interventions should address modifiable factors, including bedtime regularity and access to medical homes. Further research and policy efforts should be made to improve adherence to guidelines among autistic children and subsequently reduce health disparities.

Childhood Family Income and Adult Cardiovascular Health: Indirect Effects Through Childhood Neighborhood Socioeconomic Advantages and Disadvantages in a Prospective Sample of Young Men

BACKGROUND

Childhood family income may impact men's cardiovascular health (CVH), partly through exposure to neighborhood advantages and disadvantages experienced across childhood.

METHODS AND RESULTS

One hundred thirty-one boys (52.7% Black or bi/multiracial) born into low-income households in an urban environment were followed throughout childhood and completed a health assessment in adulthood. Childhood family income and home addresses were collected when participants were ages 1.5 to 17 years (13 waves). Annual income was averaged across waves to calculate mean childhood family income. Addresses were geocoded and linked with Census data to estimate neighborhood socioeconomic advantage and disadvantage at the Census-tract level and averaged across waves to estimate cumulative childhood neighborhood advantage and disadvantage. At age 32 years, participants underwent a physiological assessment, and CVH was estimated using Life's Essential 8 metrics: body mass index, blood pressure, cholesterol, glycated hemoglobin, sleep, smoking, and physical activity (diet not available). The Hayes' MEDCURVE macro was used to estimate indirect effects of childhood family income on adult CVH through neighborhood socioeconomic advantage and disadvantage across childhood. Higher childhood family income was associated with better CVH among men through greater exposure to childhood neighborhood advantage. Greater childhood family income was also protective for men's CVH through reduced exposure to childhood neighborhood disadvantage; however, the indirect effect through neighborhood disadvantage varied by childhood income and was the most robust among men raised in relatively higher-income households throughout childhood.

CONCLUSIONS

Improving socioeconomic neighborhood conditions may have the potential to benefit adult CVH among racially diverse boys born into low-income urban environments.

Sleep Profiles Among Ethnically-Racially Minoritized Adolescents: Associations with Sociocultural Experiences and Developmental Outcomes

OBJECTIVE

This study used latent profile analyses to (1) identify heterogeneous patterns of sleep profiles; (2) examine how discrimination was related to sleep profiles; and (3) investigate how developmental outcomes varied across sleep profiles among ethnically-racially minoritized adolescents.

METHOD

Participants were 350 ethnically-racially minoritized adolescents (69% female; 22% Black-African American, 41% Asian American, and 37% Latinx; Mage = 14.27 years old, SD = 0.61) completed self-reported presurvey measures of everyday discrimination, ethnic-racial discrimination, and self-reported post-survey measures of depressive symptoms, somatic symptoms, self-esteem, and rumination. Objectively and subjectively measured sleep were assessed utilizing a short-term longitudinal (i.e., two-week) design, where adolescents wore a wrist actigraph and completed daily diaries for 14 consecutive days.

RESULTS

Drawing on multiple objectively and subjectively measured sleep indicators, three profiles were identified: Nighttime Sleeper (76.57%), Disrupted Sleeper (14.29%), and Daytime Sleeper (9.14%). Adolescents experiencing higher levels of ethnic-racial discrimination were more likely to be characterized in the Disrupted Sleeper, relative to the Nighttime Sleeper profile. Compared with Asian and Latinx Americans, Black adolescents were more likely to be in the Daytime Sleeper, relative to the Nighttime Sleeper profile. Those in the Disrupted Sleeper profile exhibited the worst developmental outcomes.

CONCLUSIONS

The findings inform clinical interventions focusing on sleep experiences, especially as they relate to protective processes for coping with discrimination. Clinical efforts (e.g., sleep education or therapy to develop routines for adaptive napping) may be beneficial to facilitating healthy sleep behaviors and mitigating sleep disturbances, which in turn, improve developmental well-being among ethnically-racially minoritized adolescents.

Scoping Review of Socio-Ecological Factors Contributing to Sleep Health Disparities in Children with Autism Spectrum Disorder

Given the high prevalence of sleep problems in children with autism spectrum disorder (ASD), there is a critical need to examine how sleep problems may be exacerbated for children exposed to social and environmental adversity. Guided by the socio-ecological model, this review aimed to evaluate factors linked to sleep health disparities (SHDs) in children with ASD, determine possible gaps/limitations in existing literature, and identify possible solutions. A scoping review was selected to ascertain what is known about SHDs in ASD. Four databases identified articles from 2004 to 2023. Included articles were those conducted in children with ASD that focused on sleep and examined socio-ecological factors (i.e., individual, family, neighborhood and socio-cultural) possibly contributing to SHDs. 41 studies were extracted; 31 (75.6%) focused on individual factors, 27 (65.9%) focused on family factors, 11 (26.8%) focused on neighborhood and/or socio-cultural factors; 3 (7.3%) focused on factors across all three socio-ecological levels. Six studies included interventions that found improvements in child sleep, behavior, and quality of life. Representation of racial and ethnic minoritized groups was limited across studies. Most studies focused on individual child factors associated with sleep problems, with less research focused on family factors, and very few studies examining broader neighborhood and socio-cultural factors. Only about half of studies reported race and ethnicity data, with sparse representation of racial and ethnic minoritized children and families overall. These findings highlight the need for future research on modifiable socio-ecological factors to guide equitable sleep interventions for children with ASD.

Multisystem Interconnected Lifestyle Framework: A Holistic Approach to Examining the Lifestyle Determinants of Obesity in Early Childhood

This report proposes the multisystem interconnected lifestyle (MIL) framework to describe how lifestyle behaviors (i.e., sleep, stress, activity, diet) work together to create profiles of young children's obesogenic risk. This report argues that considering lifestyle behaviors collectively within and across days more accurately captures the complexity of obesity risk. The MIL framework builds on social ecological models to situate lifestyle behavior profiles within the social connections and ecological contexts of children's lives. The MIL framework potentiates the next generation of obesity research, reflecting a holistic understanding of lifestyle behavior engagement that could inform more effective and targeted education and intervention approaches.

Designing Health Interventions to Meet the Needs and Experiences of Minoritized Adolescents: #DoubleTap4Health

Engagement in preventive health behaviors (PHBs; i.e., healthy eating, sleep, and physical activity) during adolescence is associated with reduced risks for chronic conditions, such as diabetes, in adulthood. Although several interventions seek to improve adolescents' engagement in health promoting behaviors, racial- and income-based disparities across PHBs persist and may be even more pronounced for adolescents with multiple minoritized identities (e.g., Black adolescents in low-income communities). Therefore, targeted interventions that better meet the needs of minoritized adolescents are critical. The design of such interventions should include: (1) adolescent involvement, (2) cultural tailoring, (3) developmental theory, and (4) consideration of the social determinants of health. This article describes how these elements have been successfully incorporated into adolescent preventive health interventions and used to design #DoubleTap4Health, a community-based social media health intervention for Black adolescents from a low-income community. The results of a feasibility pilot of #DoubleTap4Health suggest that (1) attention to these elements in the intervention design process is feasible and advantageous to ensuring that the intervention components are appropriate and well received by adolescents, and (2) the intervention demonstrated promise as adolescents showed improved engagement in PHBs and media literacy skills. Lessons learned and next steps for intervention development are discussed. Including the above four elements in the design of preventive health interventions for adolescents from minoritized communities is critical to promoting health equity.

The Association Between School Connectedness and Sleep Health in Children and Adolescents: A Systematic Review

Schools are key settings for sleep health promotion and interventions. Yet their value as rich social-emotional environments that shape student health and wellbeing has largely been neglected by sleep research. School connectedness reflects students' engagement with learning and sense of belonging with peers, teachers, and the school environment. Although school connectedness is associated with physical and mental health in children and adolescents, whether it is associated with sleep is unclear. To address this gap, we systematically reviewed the evidence for cross-sectional and prospective associations between school connectedness and sleep. We searched Medline, PubMed, PsycINFO, and ERIC databases for observational and intervention studies published from 1950 to 17th July 2024 that examined relationships between school connectedness and sleep health or sleep problems/disorders in four- to 24-year-olds. We identified ten eligible studies (seven cross-sectional and three longitudinal) for narrative synthesis. Studies were primarily from China and Taiwan (n = 6) and conducted in secondary schools (n = 8). Participants were 14.5 years old, on average. Most of the cross-sectional studies found a positive relationship between school connectedness and sleep health. All longitudinal studies reported at least one significant relationship between school connectedness and sleep health, however two of these studies also reported non-significant relationships. We did not identify any intervention studies. Most studies were rated as 'fair' quality representing a moderate risk of bias. The findings of this review suggest that school connectedness is linked to some aspects of sleep health and insomnia in secondary-school aged adolescents. Longitudinal studies are needed to explore prospective relationships in addition to studies conducted in primary and tertiary education settings.

Impact of daily neighborhood crime on nightly sleep among adolescents

Crime impacts both the immediate victims and has indirect effects on the community. This study examined associations between daily neighborhood crime and actigraphy-assessed sleep outcomes using multilevel modeling. Data were from a longitudinal (14-day) study of 288 adolescents (Mage = 15.27; 70.8% girls, 29.2% boys; 38.9% Asian, 36.8% Hispanic or Latinx, 20.5% Black or African American) in the New York City area in 2014. Residential addresses were geocoded to examine police-recorded crime. Daily neighborhood violent crime was associated with nightly sleep efficiency, but not duration, bedtime, or wake time. Non-violent crime was not associated with any sleep outcomes. This suggests that neighborhood violent crimes are detrimental to the quality, but not quantity or timing, of sleep that adolescents receive that evening.

Built environment and chronic kidney disease: current state and future directions

PURPOSE OF REVIEW

Despite emerging studies on neighborhood-level risk factors for chronic kidney disease (CKD), our understanding of the causal links between neighborhood characteristics and CKD is limited. In particular, there is a gap in identifying modifiable neighborhood factors, such as the built environment, in preventing CKD, that could be targets for feasible place-based interventions.

RECENT FINDINGS

Most published studies on neighborhood factors and CKD have focused on a single social attribute, such as neighborhood disadvantage, while research on the role of the built environment is more nascent. Early studies on this topic have yielded inconsistent results, particularly regarding whether food deserts are an environmental risk factor for CKD onset. International studies have shown that walkable neighborhoods - characterized by features such as urban design, park access, and green spaces - can be protective against both the onset and progression of CKD. However, these findings are inconclusive and understudied in the context of United States, where neighborhood environments differ from those in other countries.

SUMMARY

Future research on modifiable neighborhood factors and CKD using advanced study designs and population-representative datasets can yield stronger evidence on potential causal associations and suggest feasible place-based interventions as strategies for preventing CKD. As an example, we demonstrated the potential of electronic health record-based studies to advance research in this area.

Income inequality and adherence to 24-hour movement guideline recommendations among adolescents: a multilevel growth curve analysis using longitudinal data from three waves of the Cannabis, Obesity, Mental health, Physical activity, Sedentary behaviour and Smoking (COMPASS) study (2016-2019)

BACKGROUND

There is a paucity of literature regarding income inequality and adolescent movement behaviours (physical activity, sedentary behaviours, sleep). This study examined whether income inequality was associated with meeting Canadian 24-Hour Movement Guidelines (24HMG) recommendations among adolescents over time.

METHODS

Longitudinal data from adolescents (n=9299) in the Cannabis, Obesity, Mental health, Physical activity, Sedentary behaviour and Smoking study (2016-2017 to 2018-2019) were linked with income data at the census division (CD) level from the 2016 Canadian Census. Adolescents (aged 13-19 years) reported on their physical activity, sleep duration and screen time via questionnaire. Gini coefficients were calculated at the CD level using after-tax household income from the 2016 Canadian Census. Multilevel logistic regression analyses were performed to test the association between income inequality and meeting several 24HMG recommendations.

RESULTS

The joint effect (income inequality*time) was significant for meeting the sleep duration recommendation (2017-2018 OR=0.83, 95% CI 0.74, 0.92; 2018-2019 OR=0.77, 95% CI 0.70, 0.86; p<0.0001), meeting any two recommendations over time (2017-2018 OR=0.97, 95% CI 0.86, 1.09; 2018-2019 OR=0.85, 95% CI 0.75, 0.97; p=0.0402) and meeting combined sleep and physical activity recommendations (2017-2018 OR=0.93, 95% CI 0.82, 1.06; 2018-2019 OR=0.82, 95% CI 0.71, 0.94; p=0.0200). Joint effects (income inequality*time) were not significant (p>0.05) for screen time or physical activity independently of sleep.

CONCLUSION

Adolescents attending schools in areas with greater income inequality may be at higher risk for inadequate sleep and combined short sleep and physical inactivity.

The impact of race, ethnicity, and socioeconomic status on early adolescent sleep disturbances for youth exposed to adverse childhood experiences

BACKGROUND

Adverse childhood experiences (ACEs) may increase the risk for adolescent sleep disturbances, though the impact of race, ethnicity, and socioeconomic status (SES) remains unclear.

OBJECTIVE

We sought to determine the direct and moderating impact of race, ethnicity, family SES, and community SES on sleep disturbances across early adolescence for ACE-exposed youth.

PARTICIPANTS AND SETTING

This secondary analysis used longitudinal Adolescent Brain Cognitive Development Study® data (2016-2022) from youth who experienced ≥1 ACE by age 9-10 years.

METHODS

Clinically significant sleep disturbances were identified from the annual parent-reported Sleep Disturbances Scale for Children. Parents reported youths' race, ethnicity, family SES, and community SES at baseline. Multilevel mixed effects logistic regression modeling examined the impact of race, ethnicity, and SES on sleep disturbances over four years among ACE-exposed youth. Adjusted odds ratios with 95 % confidence intervals are presented (adj. OR [95 % CI]).

RESULTS

Among 6661 youth with ACE exposure, 2402 (36.1 %) had clinically significant sleep disturbances at baseline. Multiracial (versus White) youth were 27 % likelier to have clinically significant sleep disturbances over time (adj. OR 1.27 [95 % CI 1.01, 1.59]). Similar results were found for youth exposed to ≥2 family financial adversities (adj. OR 1.50 [95 % CI 1.19, 1.90]). There were no effects of community SES, nor interaction effects of race, ACEs, or SES on sleep disturbances.

CONCLUSION

While Multiracial youth may experience additional stressors which affect sleep disturbances, regularly assessing family environments and supporting all families to meet basic needs may positively impact adolescent sleep.

Environmental perceptions, self-regulation, and coping with noise mediate the associations between children's physical environment and sleep and mental health problems

BACKGROUND

Children face various challenges in their home and extended neighborhood settings. In this study, we examine the impact of the built and social environments on sleep/mental health and the potential mediating role of environmental perceptions, self-regulation, and coping with noise.

METHODS

Cross-sectional data for 1251 schoolchildren (8-12 years) were sampled in the Tyrol region of Austria/Italy. Questionnaires provided information on sociodemographic and housing factors, perceived neighborhood quality, coping with noise during homework, self-regulation, sleep, and mental health problems. A built environment score was based on modeled levels of road and rail traffic noise, nitrogen dioxide, and imperviousness density. Home garden represented availability of accessible greenspace. Associations between predictors and mental health/sleep problems were examined using quantile regressions and structural equation modeling (SEM).

RESULTS

In multivariate regressions, poor neighborhood quality, poor self-regulation, low traffic safety, and higher coping efforts were associated with more mental health and sleep problems. Good family relations acted in the opposite direction. In SEM, the built environment score was associated with lower neighborhood quality and lower traffic safety, which in turn led to higher coping efforts, and then to mental health/sleep problems. Home gardens related to less sleep problems through higher perceived neighborhood quality and lower coping efforts. Good family relations were associated with better mental health/sleep directly and via better self-regulation and lower coping efforts.

CONCLUSIONS

Children forced to engage in coping activities when disturbed by noise during homework show poorer mental health. Good family relations, good neighborhood quality, and close-by greenspace may be factors to alleviate built environment stressors. The negative association of required coping with noise during homework suggests that children, in contrast to adults, may be limited in their coping abilities. Our findings call for further inquiries, as children and their environments may vary with respect to coping efficiency.

Sleep Health Disparities

Sleep is an important and potentially modifiable determinant of many severe health outcomes. Sleep health disparities exist and are exemplified by reported differential rates of prevalence, severity, and outcomes among minority groups and low-socioeconomic-status backgrounds. In this review we highlight the concept of sleep health, review the evidence for disparities in sleep health, examine risk factors and consequences of poor sleep health, and discuss policy implications.

Perceptions around sleep hygiene practices and beliefs among urban Black adolescents and their caregivers during the COVID-19 pandemic

OBJECTIVE

This study gathered adolescent and caregiver perspectives on sleep hygiene practices and beliefs for Black families living in low-resourced urban communities.

METHODS

Semistructured interviews were conducted with adolescents (n = 9) and caregivers (n = 9) from January-March 2021, during the COVID-19 pandemic. Interview questions included adolescent's current sleep habits, barriers, and home and neighborhood influences. Trained researchers coded data using inductive analysis and a constant comparative method to derive themes.

RESULTS

Two themes focused on sleep hygiene practices, including items used to facilitate sleep (e.g., melatonin, electronics) and COVID-19 consequences on sleep schedules. Two themes focused on sleep hygiene beliefs, including a common value on the importance of sleep and influences on caregiver's bedtime rules.

CONCLUSIONS

Findings provide important insights on sleep hygiene practices and beliefs in a historically marginalized population of Black adolescents and caregivers in urban communities to inform targeted sleep interventions, policies, and programs for optimal sleep and well-being.

Social determinants of health at multiple socio-ecological levels and sleep health in adolescents: A scoping review

Heightened sleep disturbances occur in adolescence, yet existing research has predominantly focused on individual factors linked to poor sleep and a limited set of sleep outcomes, such as sleep duration and timing. This scoping review aimed to identify the multilevel social determinants of adolescent sleep health across domains, including regularity, satisfaction/quality, alertness/sleepiness, timing, efficiency/continuity, duration, and behavior. Social determinants of health (SDoH) were categorized through a socio-ecological lens, while sleep health domains were aligned with the RU-SATED and Peds B-SATED sleep health frameworks. A systematic database search resulted in 57 studies of non-clinical adolescent and young adult populations (age 10-24 y) in North America, published between 2014 and 2022. Research gaps include 1) absence of other sleep health domains other than duration which is predicated on the included studies using a limited set of sleep outcome measures rather than a more comprehensive measurement strategy that align with the multifaceted domains of sleep health, and 2) inconsistent terminology and/or absent conceptual and operational definitions of subjective sleep reports. The findings highlight the multilevel SDoH that influence adolescent sleep health, underscoring the need for more comprehensive research. Such efforts will facilitate the development of interventions focused on fostering optimal adolescent sleep health this populations.

Sleep, Screen Behaviors, and Adverse Childhood Experiences: A Cross-Sectional Study of U.S. Children and Adolescents

To examine the associations between adverse childhood experiences (ACEs) and children's obesogenic behaviors (meeting recommendations for sleep duration and screen time) in a representative sample of U.S. children and adolescents. This study assessed data from the 2019-2020 National Survey of Children's Health. Separate multinomial logistic regressions examined the likelihood of failing to meet sleep and screen time recommendations given individual and cumulative ACE scores. 15,581 children (48% female, 32% non-White) experienced one ACE, representing 32% of the analyzed sample. Parents reported financial hardship as the most prevalent ACE (48%). After adjusting for child race/ethnicity, sex of the child, highest education in the household, and child age, we found that participants with four or more ACEs were (1) age-specific sleep recommendations compared with participants with zero ACEs (OR 1.96; 95%CI = 1.64-2.35), and (2) more likely to fall short of meeting screen use recommendations compared with participants with zero ACEs (OR 1.61; 95%CI = 1.26-2.07). U.S. children and adolescents who have experienced four or more ACEs are significantly more likely to fall short of sleep and screen time recommendations compared to their counterparts who experienced zero ACEs. Given the strong associations between ACEs and health outcomes in adulthood, screening for ACEs may better inform practitioners when attempting to improve youth health outcomes.

Community violence and asthma: A review

Over the past 2 decades, epidemiologic studies have identified significant associations between exposure to violence, as a psychosocial stressor, and the incidence or exacerbation of asthma. Across diverse populations, study designs, and measures of community violence, researchers have consistently identified adverse associations. In this review, the published epidemiologic evidence is summarized with special attention to research published in the last 5 years and seminal papers. Hypothesized mechanisms for the direct effects of violence exposure and for how such exposure affects susceptibility to physical agents (eg, air pollution and extreme temperature) are discussed. These include stress-related pathways, behavioral mechanisms, and epigenetic mechanisms. Finally, clinical implications and recommendations are discussed.

Somatomotor disconnection links sleep duration with socioeconomic context, screen time, cognition, and psychopathology

Background

Sleep is critical for healthy brain development and emotional wellbeing, especially during adolescence when sleep, behavior, and neurobiology are rapidly evolving. Theoretical reviews and empirical research have historically focused on how sleep influences mental health through its impact on higher-order brain systems. No studies have leveraged data-driven network neuroscience methods to uncover interpretable, brain-wide signatures of sleep duration in adolescence, their socio-environmental origins, or their consequences for cognition and mental health.

Methods

Here, we implement graph theory and component-based predictive modeling to examine how a multimodal index of sleep duration is associated with intrinsic brain architecture in 3,173 youth (11-12 years) from the Adolescent Brain Cognitive DevelopmentSM Study.

Results

We demonstrate that network integration/segregation exhibit a strong, generalizable multivariate association with sleep duration. We next identify a single component of brain architecture centered on a single network as the dominant contributor of this relationship. This component is characterized by increasing disconnection of a lower-order system - the somatomotor network - from other systems, with shorter sleep duration. Finally, greater somatomotor disconnection is associated with lower socioeconomic resources, longer screen times, reduced cognitive/academic performance, and elevated externalizing problems.

Conclusions

These findings reveal a novel neural signature of shorter sleep in adolescence that is intertwined with environmental risk, cognition, and psychopathology. By robustly elucidating the key involvement of an understudied brain system in sleep, cognition, and psychopathology, this study can inform theoretical and translational research directions on sleep to promote neurobehavioral development and mental health during the adolescent transition.

From Counting Dollars to Counting Sheep: Exploring Simultaneous Change in Economic Well-Being and Sleep among African American Adolescents

In the U.S.A., Black/African American adolescents disproportionately experience short and poor-quality sleep, and there is little understanding of why some experience decrements or improvements in sleep over time. Toward conducting culturally specific research and identifying processes that uniquely explain variability within a racial/ethnic group, we utilized a within-group design to examine socioeconomic status (SES) as a predictor of Black adolescents' sleep. Few studies have examined change-on-change processes in sleep over time. Contributing to the literature in novel ways, we assessed the predictive effect of change in SES over one year on changes in four actigraphy-derived sleep parameters over the same time period. Participants were 218 Black adolescents (Time 1: Mage = 17.09 years; 54.6% female) and their mothers from socioeconomically diverse backgrounds. Adolescents participated in two-waves of data collection spaced approximately one year apart. At each wave, we assessed economic well-being (used to index SES) and sleep using 7 nights of actigraphy from which we derived measures of sleep duration (minutes) and quality (efficiency, long-wake episodes, activity). Latent difference score analyses revealed that adolescents experiencing increases in SES over one year exhibited decreases in both long-wake episodes and sleep activity over one year. Findings suggest that individual differences in change in SES explain individual differences in change in adolescents' sleep quality. Notably, findings highlight the utility of within-group designs for identifying culturally specific processes that predict improvements in sleep quality in a sample at disproportionate risk for sleep and health disparities.

Sleeping Healthy, Living Healthy: Using Iterative, Participatory Processes to Develop and Adapt an Integrated Sleep Hygiene/Mind-Body Integrative Health Intervention for Urban Adolescents

Racial and ethnic minority adolescents living in urban settings experience sleep disparities. Few interventions have been developed to address these disparities. Guided by principles of participatory design and inclusion, our team developed a novel intervention that combined sleep hygiene education with mind-body integrative health (MBIH) practices to improve sleep quality among adolescents in New York City. The goal of this article is to describe our iterative development and design process, the final product, and future directions. Our participatory approach incorporated information from formative work with adolescents having lived experience, practitioners, and syntheses of published literature. The final intervention-Sleeping Healthy, Living Healthy-consists of six, 40-minute group sessions and one 20-minute individual session designed for high school students. Each session has a set of learning objectives, combining instruction, group activities, and discussions on sleep hygiene and MBIH topics. Our manualized intervention includes handouts created by a graphic design team that served as a review and reminder for home practice. We describe intervention implementation to two unique cohorts and detail our methods used to fine-tune the intervention between cohorts. Our partnership with and insights from both adolescents and practitioners serve as a guide for researchers aiming to use participatory methods to develop interventions to decrease health disparities in specific populations.

Examining the influence of problematic internet use on sleep quality in Chinese adolescents: a study using the extended Stressor-Strain-Outcome (SSO) model

Objective

This study aims to explore how problematic internet use may affect the sleep quality of Chinese adolescents using the extended Stressor-Strain-Outcome (SSO) model. The model posits that stressors indirectly influence behavioral outcomes through the mediation of emotional and physiological strain responses.

Method

A sample of 4,365 adolescents in China participated in this study, which utilized questionnaires and other methods to develop a novel SSO model. In this model, problematic internet use was considered as the stressor, anxiety as an indicator of tension, and sleep quality as the ultimate outcome. Family health was introduced as a moderating variable.

Results

The study found that problematic internet use can significantly and positively predict adolescents' anxiety (β = 0.132, p < 0.001) and sleep quality (β = 0.362, p < 0.001). Furthermore, anxiety was identified as a significant mediating factor between problematic internet use and sleep quality [Effect = 0.066, p < 0.05, 95% CI (0.014, -0.0018)]. Family health was observed to have a moderating effect on the relationship between problematic internet use and anxiety (β = -0.075, p < 0.001).

Conclusion

The research indicates that problematic internet use not only directly increases individual anxiety as a stressor but also indirectly impacts sleep quality by exacerbating anxiety. However, a positive family health status can effectively moderate the adverse impact of problematic internet use on anxiety.

Parental sleep-related practices and sleep in children aged 1-3 years: a systematic review

The current systematic review sought to identify the relationship between the range of different parental sleep-related practices that had been explored in relations to child sleep outcomes in children aged 1-3 years. A systematic literature review was carried out in CINAHL, The Cochrane Library, PsycArticles, PsycInfo, PubMed and Web of Science, as well as relevant grey literature in August 2022 using the terms; population (children, aged 1-3 years), exposure (parental sleep-related practice) and outcome (child sleep). Any quantitative study published between 2010 and 2022 that explored the relationship between parental sleep-related practices and the sleep of children aged 1-3 years were included. The Mixed Methods Appraisal Tool was employed to quality appraise included studies and results were narratively synthesised. In all, 16 longitudinal and cross-sectional quantitative studies met inclusion criteria. Parental presence or physical involvement, as well as broader parental practices including using screens or devices at bedtime and night-time breastfeeding were all related to poorer child sleep outcomes. Consistent and relaxing routines, sleeping in a cot, and spending all night in their own sleep location were associated with better child sleep outcomes. Acknowledging the plethora of diverse parental sleep-related practices, which may have varying relationships with child sleep outcomes, could be usefully considered in theoretical models and to inform clinical practice. Issues of definitional and measurement ambiguity are highlighted and discussed.

Disadvantaged social status contributed to sleep disorders: An observational and genome-wide gene-environment interaction analysis

BACKGROUND

Sleep is a natural and essential physiological need for individuals. Our study aimed to research the associations between accumulated social risks and sleep disorders.

METHODS

In this study, we came up with a polysocial risk score (PsRS), which is a cumulative social risk index composed of 13 social determinants of health. This research includes 239,165 individuals with sleep disorders and social determinants of health data from the UK Biobank cohort. First, logistic regression models were performed to examine the associations of social determinants of health and sleep disorders, including chronotype, narcolepsy, insomnia, snoring, short and long sleep duration. Then, PsRS was calculated based on statistically significant social determinants of health for each sleep disorder. Third, a genome-wide gene-environment interaction study was conducted to explore the interactions between single-nucleotide polymorphisms and PsRS in relation to sleep disorders.

RESULTS

Higher PsRS scores were associated with worse sleep status, with the adjusted odds ratio (OR) ranging from 1.10 (95% Confidence interval [CI]: 1.09-1.11) to 1.29 (95% CI: 1.27-1.30) for sleep disorders. Emotional stress (OR = 1.36, 95% CI: 1.28-1.43) and not in paid employment (OR = 2.62, 95% CI: 2.51-2.74) were found to have significant contributions for sleep disorders. Moreover, multiple single-nucleotide polymorphisms were discovered to have interactions with PsRS, such as FRAS1 (P = 2.57 × 10-14) and CACNA1A (P = 8.62 × 10-14) for narcolepsy, and ACKR3 (P = 1.24 × 10-8) for long sleep.

CONCLUSIONS

Our findings suggested that cumulative social risks was associated with sleep disorders, while the interactions between genetic susceptibility and disadvantaged social status are risk factors for the development of sleep disorders.

Associations between indoor fine particulate matter (PM2.5) and sleep-disordered breathing in an urban sample of school-aged children

OBJECTIVES

Environmental risk factors may contribute to sleep-disordered breathing. We investigated the association between indoor particulate matter ≤2.5µm in aerodynamic diameter (PM2.5) and sleep-disordered breathing in children in an urban US community.

METHODS

The sample consisted of children aged 6-12years living in predominantly low-income neighborhoods in Boston, Massachusetts. Indoor PM2.5 was measured in participants' main living areas for 7days using the Environmental Multipollutant Monitoring Assembly device. High indoor PM2.5 exposure was defined as greater than the sample weekly average 80th percentile level (≥15.6 μg/m3). Sleep-disordered breathing was defined as an Apnea-Hypopnea-Index (AHI) or Oxygen-Desaturation-Index (ODI) (≥3% desaturation) of ≥5 events/hour. Habitual loud snoring was defined as caregiver-report of loud snoring (most or all the time each week) over the past 4weeks. We examined the associations of PM2.5 with sleep-disordered breathing or snoring using logistic regression adjusting for potential confounders.

RESULTS

The sample included 260 children (mean age 9.6years; 41% female), with 32% (n = 76) classified as having sleep-disordered breathing. In a logistic regression model adjusted for socioeconomics and seasonality, children exposed to high indoor PM2.5 levels (n = 53) had a 3.53-fold increased odds for sleep-disordered breathing (95%CI: 1.57, 8.11, p = .002) compared to those with lower indoor PM2.5. This association persisted after additional adjustments for physical activity, outdoor PM2.5, environmental tobacco smoke, and health characteristics. Similar associations were observed for snoring and indoor PM2.5. CONCLUSIONS: Children with higher indoor PM2.5 exposure had greater odds of sleep-disordered breathing and habitual loud snoring, suggesting that indoor air quality contributes to sleep disparities.

Diagnosis of sleep disorders in child healthcare settings

OBJECTIVES

Sleep disorders impact at least 10 % of children, pose risks to overall wellbeing, and are key targets of preventive interventions. The objectives of this study were to describe the prevalence of pediatric sleep disorder diagnoses across sociodemographic characteristics and co-occurring conditions, and to explore potential sociodemographic disparities.

METHODS

Cross-sectional analysis of 12,394,902 children (0-17 years; 50.9 % Medicaid-insured) in the 2017 MarketScan database. Prevalence was assessed utilizing ICD-10 codes, with multivariate logistic regressions examining disparities (insurance coverage; race and ethnicity in Medicaid-insured) for diagnoses in ≥0.10 % of children.

RESULTS

The prevalence of sleep disorder diagnoses was 2.36 %. The most common diagnoses were obstructive sleep disordered breathing (oSDB, 1.17 %), unspecified sleep disorders (0.64 %), insomnia (0.52 %), and other SDB (0.10 %), with <0.10 % for all other diagnoses. Insomnia and parasomnias diagnoses were much lower than diagnostic estimates. Sleep diagnoses were more prevalent in Medicaid versus commercially insured youth, 2-5-year-olds, and in children with co-occurring medical, neurodevelopmental, or behavioral health conditions. Girls and boys were generally equally likely to be diagnosed with any sleep disorder. In Medicaid-insured children, white children were more likely to have any sleep diagnosis compared to all other racial and ethnic groups. Black/African American children were more likely than white children to have oSDB.

CONCLUSIONS

Compared to diagnostic estimates, claims data suggest sleep disorders are under-diagnosed, with notable sociodemographic disparities. Findings suggest a need for clinical resources to identify and address sleep disorders and to understand biases potentially driving disparities, given that sleep is a modifiable determinant of child wellbeing.

The relationship between neighborhood social capital and health from a biopsychosocial perspective: A systematic review

BACKGROUND

The Social Determinants of Health (SDH) influence the health of people throughout their lives, and can be positive, protective or risk factors for the population and, in turn, biological, psychological, or social. The social environment conditions the health status of the neighborhood, population, and social group, which can be a health asset due to its strong psychosocial and socio-cultural influence. Social capital is a community asset of the healthy neighborhood that must be known in order to promote community health.

OBJECTIVES

The objective is to determine the relationship between social capital and neighborhood biopsychosocial health.

METHODS

A systematic review was conducted based on PRISMA: PubMed, Wos, Scopus, Embase, and Cochrane databases. The search was conducted from January to March 2023. Three authors independently extracted data using a structured form.

RESULTS

Out of 527 records, 17 results passed the inclusion and exclusion criteria. The positive and statistically significant relationship between neighborhood social capital (NSC) and the physical and mental health of neighbors is confirmed, that is, the higher the NSC, the more exercise, better oral health in children and physical health in pregnant women, lower tobacco consumption and lower prevalence of human immunodeficiency virus. At the psychological level, greater NSC leads to better mental health, mental well-being, life satisfaction, quality of life, self-perceived health, higher cognitive function, and less depression.

CONCLUSIONS

In conclusion, social capital is an important SDH and health asset that influences neighborhood biopsychosocial health and should be known and researched for health promotion in community settings. More evidence is needed to support the results obtained.

Mechanisms underlying the associations between different types of nature exposure and sleep duration: An 18-country analysis

Whilst green space has been linked to healthier sleep outcomes, the roles of specific types of nature exposure, potential underlying mechanisms, and between-country variations in nature-sleep associations have received little attention. Drawing on cross-sectional survey data from an 18-country sample of adults (N = 16,077) the current study examined: 1) the relative associations between six different types of nature exposure (streetscape greenery, blue view from home, green space within 1 km, coast within 1 km, green space visits, blue space visits) and insufficient sleep (<6 h vs. 7-10 h per day); 2) whether these relationships were mediated by better mental wellbeing and/or physical activity; and 3) the consistency of these pathways among the different countries. After controlling for covariates, neighbourhood nature measures (green space, coast within 1 km) were not significantly associated with insufficient sleep; but nature visible from home (streetscape greenery, blue views) and recreational visits to green and blue spaces were each associated with less insufficient sleep. Significant nature-sleep associations were mediated, to varying degrees, by better mental wellbeing, but not self-reported physical activity. Country-level heterogeneity in the strength of nature-sleep associations was observed. Increasing nature visible from the home may represent a promising strategy for promoting healthier sleep duration at the population level, whilst nature-based interventions encouraging individuals to spend time in local green/blue spaces may be an appropriate target to assist individuals affected by insufficient sleep.

Insomnia Polygenic Component on Attention Deficit-Hyperactivity Disorder: Exploring this Association Using Genomic Data from Brazilian Families

Introduction  Insomnia is highly prevalent among individuals with Attention-Deficit/Hyperactivity Disorder (ADHD). However, the biological mechanisms shared between both conditions is still elusive. We aimed to investigate whether insomnia's genomic component is able to predict ADHD in childhood and adolescence. Methods  A Brazilian sample of 259 ADHD probands and their biological parents were included in the study. Their genomic DNA genotypes were used to construct the polygenic risk score for insomnia (Insomnia PRS), using the largest GWAS summary statistics as a discovery sample. The association was tested using logistic regression, under a case-pseudocontrol design. Results  Insomnia PRS was nominally associated with ADHD (OR = 1.228, p  = 0.022), showing that the alleles that increase the risk for insomnia also increase the risk for ADHD. Discussion  Our results suggest that genetic factors associated with insomnia may play a role in the ADHD genetic etiology, with both phenotypes likely to have a shared genetic mechanism.

Self-reported neighborhood stressors and sleep quality among Puerto Rican young adults

OBJECTIVE

To examine the association between changes in self-reported neighborhood stressors and sleep quality and determine whether this varied by sociocultural context among Puerto Rican young adults.

METHODS

Data come from the Boricua Youth Study Health Assessment, a sample of Puerto Rican young adults from San Juan, Puerto Rico, and South Bronx, New York (n = 818; mean age=22.9years). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Neighborhood social stressors (disorder, social cohesion, and safety) were parent-reported in childhood and self-reported in young adulthood and categorized into: low in childhood/young adulthood (reference group), high in childhood/low in young adulthood, low in childhood/high in young adulthood, and high in childhood/young adulthood. Sociocultural context was based on participant residence during childhood (San Juan vs. South Bronx).

RESULTS

Adjusting for sociodemographic factors, living with high neighborhood stressors in both childhood and young adulthood (prevalence ratios=1.30, 95% CI: 1.01, 1.66) was associated with overall poor sleep (PSQI score >5). Among PSQI components, living with high neighborhood stressors in young adulthood only or in both time periods was associated with worse subjective sleep quality and daytime dysfunction. Additionally, there were various associations between the neighborhood stressor measures and PSQI components. Results did not differ by sociocultural context.

CONCLUSION

Findings suggest that living with high levels of neighborhood stressors during childhood and young adulthood may have a cumulative adverse impact on sleep quality in young adulthood.

Longitudinal associations between neighborhood safety and adolescent adjustment: The moderating role of affective neural sensitivity

Research on social determinants of health has highlighted the influence of neighborhood characteristics (e.g., neighborhood safety) on adolescents' health. However, it is less clear how changes in neighborhood environments play a role in adolescent development, and who are more sensitive to such changes. Utilizing the first three waves of data from the Adolescent Brain Cognitive Development (ABCD) project (N = 7932, M (SD) age = 9.93 (.63) years at T1; 51% boys), the present study found that increases in neighborhood safety were associated with decreased adolescent externalizing symptoms, internalizing symptoms, but not sleep disturbance over time, controlling for baseline neighborhood safety. Further, adolescents' insula and anterior cingulate cortex (ACC) reactivity to positive emotional stimuli moderated the association between changes in neighborhood safety and adolescent adjustment. Among youth who showed higher, but not lower, insula and ACC reactivity to positive emotion, increases in neighborhood safety were linked with better adjustment. The current study contributes to the differential susceptibility literature by identifying affective neural sensitivity as a marker of youth's susceptibility to changes in neighborhood environment. The findings highlight the importance of neighborhood safety for youth during the transition to adolescence, particularly for those with heightened affective neural sensitivity.

Socioeconomic factors, sleep timing and duration, and amygdala resting-state functional connectivity in children

Introduction

Reduced sleep health has been consistently linked with increased negative emotion in children. While sleep characteristics have been associated with neural function in adults and adolescents, much less is known about these associations in children while considering socioeconomic context. In this study, we examined the associations among socioeconomic factors, sleep duration and timing, and resting-state functional connectivity (rsFC) of the amygdala in children.

Methods

Participants were typically-developing 5- to 9-year-olds from socioeconomically diverse families (61% female; N = 94). Parents reported on children's weekday and weekend bedtimes and wake-up times, which were used to compute sleep duration and midpoint. Analyses focused on amygdala-anterior cingulate cortex (ACC) connectivity followed by amygdala-whole brain connectivity.

Results

Lower family income-to-needs ratio and parental education were significantly associated with later weekday and weekend sleep timing and shorter weekday sleep duration. Shorter weekday sleep duration was associated with decreased amygdala-ACC and amygdala-insula connectivity. Later weekend sleep midpoint was associated with decreased amygdala-paracingulate cortex and amygdala-postcentral gyrus connectivity. Socioeconomic factors were indirectly associated with connectivity in these circuits via sleep duration and timing.

Discussion

These results suggest that socioeconomic disadvantage may interfere with both sleep duration and timing, in turn possibly altering amygdala connectivity in emotion processing and regulation circuits in children. Effective strategies supporting family economic conditions may have benefits for sleep health and brain development in children.

The cross-sectional and prospective associations of parental practices and environmental factors with 24-hour movement behaviours among school-aged Asian children

BACKGROUND

Parental practices and neighbourhood environmental factors may influence children's movement behaviours. We aimed to investigate the cross-sectional and prospective associations of parental practices and neighbourhood environmental factors with accelerometer-measured 24-hour movement behaviours (24 h-MBs) among school-aged children in Singapore.

METHODS

The Growing Up in Singapore Towards healthy Outcomes (GUSTO) study collected information on dimensions of parental practices and neighbourhood environment at age 5.5 years. Confirmatory factor analyses were performed to generate latent variables and used to compute overall parental practices [involvement in PA + support for PA + control of screen viewing context] and environmental scores [facilities for active play + active mobility facilitators + barriers*-1]. Children wore an accelerometer on their non-dominant wrist for seven consecutive days at ages 5.5 and 8 years. The R-package GGIR 2.6 was used to derive moderate-to-vigorous-intensity physical activity (MVPA), light-intensity physical activity (LPA), inactivity, and total-sleep (napping+night sleep) minutes per day. Associations were determined using compositional data analysis with multivariate linear regression models, taking into account potential confounders.

RESULTS

Among 425 children (48% girls, 59% Chinese), higher parental involvement in PA, parental support for PA and overall parental practices were associated with 24 h-MBs at ages 5.5 and 8 years, specifically with greater time spent in MVPA and less time being inactive relative to the remaining movement behaviours. The corresponding mean changes in the overall 24 h-MB for increasing parental practices from lowest to highest scores (- 2 to + 2 z-scores) indicated potential increases of up to 15-minutes in MVPA, 20-minutes in LPA, 5-minutes in sleep duration, and a reduction of 40-minutes in inactivity at age 5.5 years. At age 8 years, this could translate to approximately 15-minutes more of MVPA, 20-minutes more of LPA, a 20-minute reduction in sleep duration, and a 20-minute reduction in inactivity. Parental control of screen viewing contexts and neighbourhood environmental factors were not associated with 24 h-MBs.

CONCLUSIONS

Parental practices but not environmental factors were associated with higher MVPA and lower inactivity among Singaporean children, even at a later age. Further research may provide insights that support development of targeted public health strategies to promote healthier movement behaviours among children.

Trying to Do What's Best: Maternal Perspectives About Toddler Sleep Health Among an Underresourced Sample of Mothers With Diverse Racial and Ethnic Identities

INTRODUCTION

This study describes mothers' knowledge, attitudes, beliefs, and practices about their toddler's sleep health among an underresourced sample of mothers with diverse racial and ethnic identities.

METHOD

This was a descriptive qualitative study with 16 mothers and their 12- to 36-month-old child. Mothers completed a semistructured, audio-recorded interview about their toddler's sleep health. Data were analyzed using inductive content analysis on the basis of established methods.

RESULTS

Mothers self-identified as 18.8% Black, 43.8% White, 12.5% multiracial, 25.0% other race, and 37.5% Hispanic. Of the mothers, 80.0% reported a past year household income of ≤ $40,000. A core construct, "Trying to do What's Best," emerged from the interview data, and this construct included three domains: Getting Good Sleep, Getting Thrown Off, and Rolling With It.

DISCUSSION

Findings support future strengths-based and multilevel sleep health-promoting interventions.

Individual and cumulative firearm violence exposure: Implications for sleep among Black and American Indian/Alaska Native adults

PURPOSE

We investigated the relationship between various forms of firearm violence exposure and sleep problems among nationally representative samples of Black (N = 3015) and American Indian and Alaska Native (AI/AN) (N = 527) adults, focusing on difficulties falling asleep, staying asleep, and waking too early. Survey data were collected in April and May 2023.

METHODS

We employed negative binomial regression models to analyze the associations between the different types of firearm violence exposure and sleep problems. We further examined associations between cumulative firearm violence exposure and sleep outcomes.

RESULTS

A substantial proportion of Black (59%) and AI/AN (56%) adults reported experiencing some form of firearm violence exposure. Being threatened with a firearm emerged as a consistent factor associated with sleep problems for both racial groups. Witnessing or hearing about shootings was linked to sleep problems in the Black sample, while cumulative firearm violence exposure was associated with all sleep problems in both groups.

CONCLUSIONS

Individual and cumulative firearm violence exposure is associated with increased sleep problems among Black and AI/AN adults.

Neighborhood-level sleep health and childhood opportunities

Objectives

Regional sleep differences may reflect other important indicators of health and well-being. Examining sleep health at the regional level can help inform policies to improve population health. We examined the relationship between neighborhood-level adult sleep health (modeled in this study via adult sleep duration) and other health metrics and multiple indicators of child-relevant opportunity.

Methods

Data were obtained from the "500 Cities" data collected by the CDC, including the proportion of the adult population in each tract that report obtaining at least 7 h of sleep. The Child Opportunity Index (COI) provides indices for "education," "health and environment," and "social and economic" domains, as well as a global score. When data were merged, 27,130 census tracts were included. Linear regression analyses examined COI associated with the proportion of the adult population obtaining 7 h of sleep.

Results

Adult sleep duration was associated with global COI, such that for each additional percent of the population that obtains ≥ 7 h of sleep, COI increases by 3.6 points (95%CI[3.57, 3.64]). Each component of COI was separately related to adult sleep duration. All associations were attenuated but significant in adjusted analyses. In stepwise analyses, sleep health via adult sleep duration emerged as the strongest correlate of global COI, accounting for 57.2% of the variance (p < 0.0001). Similarly, when stepwise analyses examined each component of COI as dependent variable, sleep health consistently emerged as the most substantial correlate (all p < 0.0001).

Conclusion

Community levels of sufficient sleep are associated with greater childhood opportunities, which itself is robustly associated with a wide range of health and economic outcomes. Future work can examine whether this association can develop into scalable interventions.

Perceived Neighborhood Characteristics and Sleep in Australian Adults

BACKGROUND

Poor sleep can contribute to poorer health and socioemotional outcomes. Sleep health can be influenced by a range of individual and other socioecological factors. Perceptions of neighborhood physical and social characteristics reflect broader social-level factors that may influence sleep, which have not been well studied in the Australian context. This study examined the association between perceived neighborhood characteristics and sleep in a large sample of Australians.

METHODS

Data were from 9,792 people aged 16 years or older, from Waves 16 and 17 of the nationally representative Household, Income and Labour Dynamics in Australia Survey. Associations between perceived neighborhood characteristics (neighborly interaction and support, environmental noise, physical condition, and insecurity) and self-reported sleep duration, sleep disturbance, and napping were examined using multiple logistic regression models.

RESULTS

"Neighborhood interaction and support" and "neighborhood physical condition" were not significantly associated with any sleep outcomes after adjusting for relevant covariates. However, "environmental noise" and "neighborhood insecurity" remained significantly associated with sleep duration and sleep disturbance. None of the neighborhood characteristics were associated with napping. Furthermore, associations did not significantly vary by gender.

CONCLUSIONS

This study highlights the potential benefit of public health policies to address noise and safety in neighborhoods to improve sleep.

Neighborhood determinants of sleep and the moderating role of cultural factors among native adolescents

OBJECTIVE

This study examined the association between neighborhood social environment and sleep among urban American Indian and Alaska Native (AI/AN) adolescents as well as the moderating role of cultural factors in this association.

METHOD

The analytic sample included 133 urban AI/AN adolescents (age 12-16, 57.1% female, Mage = 14.03, SDage = 1.35). Perceived neighborhood social environment included safety and cohesion. Cultural factors included AI/AN cultural identification and historical loss. Sleep duration, efficiency, and wake after sleep onset (WASO) were measured via actigraphy. Sleep disturbance was measured via a questionnaire.

RESULTS

Greater neighborhood safety was significantly associated with lower sleep disturbance (b = -2.17, SE = 0.8, p = .008), higher sleep efficiency (b = 1.75, SE = 0.64, p = .006), and lower WASO (b = -8.60, SE = 3.34, p = .01). Neighborhood cohesion was not associated with any sleep outcomes. Cultural factors moderated the association between neighborhood social environment and sleep outcomes (p < .05). Specifically, both neighborhood safety and cohesion were associated with lower sleep disturbance, only among individuals reporting higher levels of AI/AN cultural identification. Further, neighborhood safety was associated with greater sleep efficiency and lower WASO (i.e., better sleep) only among adolescents with higher contemplation of historical loss.

CONCLUSIONS

Findings highlight the importance of considering cultural factors in addressing sleep and health disparities. AI/AN cultural identification and a sense of historical loss may be important targets for identifying adolescents who might benefit the most from policies and interventions focused on improving the social environment in order to improve sleep and other health outcomes.

Neighborhood predictors of short sleep duration and bedtime irregularity among children in the United States: results from the 2019-2020 National Survey of Children's Health

BACKGROUND

Environmental factors may contribute to short sleep duration and irregular bedtime in children. Neighborhood factors and children's sleep duration and bedtime regularity remain a less investigated area. The aim of this study was to investigate the national and state-level proportions of children with short sleep duration and irregular bedtime and their neighborhood predictors.

METHODS

A total of 67,598 children whose parents completed the National Survey of Children's Health in 2019-2020 were included in the analysis. Survey-weighted Poisson regression was used to explore the neighborhood predictors of children's short sleep duration and irregular bedtime.

RESULTS

The prevalence of short sleep duration and irregular bedtime among children in the United States (US) was 34.6% [95% confidence interval (CI) = 33.8%-35.4%] and 16.4% (95% CI = 15.6%-17.2%) in 2019-2020, respectively. Safe neighborhoods, supportive neighborhoods, and neighborhoods with amenities were found to be protective factors against children's short sleep duration, with risk ratios ranging between 0.92 and 0.94, P < 0.05. Neighborhoods with detracting elements were associated with an increased risk of short sleep duration [risk ratio (RR) = 1.06, 95% CI = 1.00-1.12] and irregular bedtime (RR = 1.15, 95% CI = 1.03-1.28). Child race/ethnicity moderated the relationship between neighborhood with amenities and short sleep duration.

CONCLUSIONS

Insufficient sleep duration and irregular bedtime were highly prevalent among US children. A favorable neighborhood environment can decrease children's risk of short sleep duration and irregular bedtime. Improving the neighborhood environment has implications for children's sleep health, especially for children from minority racial/ethnic groups.

Multilevel Risk Factors for Sleep-Disordered Breathing-Related Symptom Burden in an Urban Pediatric Community-Based Sample

BACKGROUND

Pediatric sleep-disordered breathing (SDB) disproportionately affects children with low socioeconomic status (SES). The multilevel risk factors that drive these associations are not well understood.

RESEARCH QUESTION

What are the associations between SDB risk factors, including individual health conditions (obesity, asthma, and allergies), household SES (maternal education), indoor exposures (environmental tobacco smoke [ETS] and pests), and neighborhood characteristics (neighborhood disadvantage), and pediatric SDB symptoms?

STUDY DESIGN AND METHODS

Cross-sectional analyses were performed on 303 children (aged 6-12 years) enrolled in the Environmental Assessment of Sleep Youth study from 2018 to 2022. Exposures were determined by caregiver reports, assays of measured settled dust from the child's bedroom, and neighborhood-level Census data (deriving the Childhood Opportunity Index to characterize neighborhood disadvantage). The primary outcome was the SDB-related symptom burden assessed by the OSA-18 questionnaire total score. Using linear regression models, we calculated associations between exposures and SDB-related symptom burden, adjusting for sociodemographic factors, then health conditions, indoor environment, and neighborhood factors.

RESULTS

The sample included 303 children (39% Hispanic, Latino, Latina, or Spanish origin; 30% Black or African American; 22% White; and 11% other). Increasing OSA-18 total scores were associated with low household SES after adjustment for demographic factors, and with asthma, allergies, ETS, pests (mouse, cockroach, and rodents), and an indoor environmental index (sum of the presence of pests and ETS; 0-2) after adjusting for sociodemographic factors. Even after further adjusting for asthma, allergies, and neighborhood disadvantage, ETS and pest exposure were associated with OSA-18 (ETS: β = 12.80; 95% CI, 7.07-18.53, also adjusted for pest; pest exposure: β = 3.69; 95% CI, 0.44-6.94, also adjusted for ETS).

INTERPRETATION

In addition to associations with ETS, a novel association was observed for indoor pest exposure and SDB symptom burden. Strategies to reduce household exposure to ETS and indoor allergens should be tested as approaches for reducing sleep health disparities.

Neighborhood and Household Environment as Contributors to Racial Disparities in Sleep Duration among U.S. Adolescents

Objective

Racial disparities in adolescent sleep duration have been documented, but pathways driving these disparities are not well understood. This study examined whether neighborhood and household environments explained racial disparities in adolescent sleep duration.

Methods

Participants came from Waves I and II of Add Health (n=13,019). Self-reported short sleep duration was defined as less than the recommended amount for age (<9 hours for 6-12 years, <8 hours for 13-18 years, and <7 hours for 18-64 years). Neighborhood factors included neighborhood socioeconomic disadvantage, perceived safety and social cohesion. Household factors included living in a single parent household and household socioeconomic status (HSES). Structural equation modeling was used to assess mediation of the neighborhood and household environment in the association between race/ethnicity and short sleep duration.

Results

Only HSES mediated racial disparities, explaining non-Hispanic (NH) African American-NH White (11.6%), NH American Indian-NH White (9.9%), and Latinx-NH White (42.4%) differences. Unexpectedly, higher HSES was positively associated with short sleep duration.

Conclusion

Household SES may be an important pathway explaining racial disparities in adolescent sleep duration. Future studies should examine mechanisms linking household SES to sleep and identify buffers for racial/ethnic minority adolescents against the detrimental impacts that living in a higher household SES may have on sleep.

The Association Between Socioeconomic Status and Use of Time in Australian Children and Adolescents

PURPOSE

There are well-known socioeconomic status (SES) gradients in children and adolescents' health which may be associated with time use. Our aim was to evaluate the association between Australian children's 24-hour time use and SES using four separate surveys from 2005 to 2021.

METHODS

Time use was assessed in 4526 8-19-year-olds from the 2005 Health of Young Victorians, 2007 National Children's Nutrition and Physical Activity, 2015 Child Health CheckPoint, and 2019-21 Life on Holidays study. Each survey used the same reliable, valid, 24-hour recall instrument. SES was quantified using tertiles of household income, education, and postcode-level measures. Compositional data analysis was used to compare 24-hour time use between SES categories, adjusting for age, sex, and puberty.

RESULTS

Time-use compositions differed significantly by SES in each survey. Relative to the lowest SES, children from the highest SES accumulated on average 31 min/day more School-related time, 6 min/day more Passive Transport and 6 min/day more Self-care. Conversely, they accumulated 30 min/day less Screen Time (which included computer time), 11 min/day less sleep, and spent 7 min/day less in Domestic/Social activities. There were only small differences in Quiet Time and Physical Activity.

DISCUSSION

SES-related differences in time use were robust across ages 8-19, a 16-year timespan, diverse Australian geographical regions, and using different SES metrics. The exchange of about 30 min/day between School-related activities and Screen Time amounts to >180 hours extra exposure to School-related activities annually in the highest SES category relative to the lowest, equivalent to >6 weeks of school time per year.

Social disparities in sleep health of African populations: A systematic review and meta-analysis of observational studies

OBJECTIVES

To document the relationship between socioeconomic status (SES) and sleep health in African populations.

METHODS

Observational cross-sectional or cohort studies examining the association between SES indicators and sleep outcomes in participants from African countries were included. The search was performed in the MEDLINE, Embase, and Web of Science Core Collection electronic databases in June 2021. Selection, confounding, attrition/exclusion, detection, and selective reporting bias were assessed using the OHAT Risk of Bias Tool. Random effects meta-analysis was used for summarizing the effect estimates.

RESULTS

Forty-three reports were selected, having sampled 153,372 Africans from 26 countries. Education was the most frequent SES indicator and composite measures of sleep quality or disturbances was the most common sleep outcome. Low educational attainment was significantly associated with lower odds of short sleep (odds ratio [OR]=0.65, 95% confidence intervals [0.50, 0.84], p = .001) and higher odds of insomnia (OR=1.53, [1.18, 1.99], p = .001) or poor sleep quality (OR=1.60, [1.17, 2.18], p = .003). Low levels of income/assets were related to higher odds of insomnia (OR=1.38, [1.02, 1.86], p = .04) and low occupational/employment status was linked to lower odds of short sleep duration (OR=0.49, [0.30, 0.79], p = .004).

CONCLUSIONS

Socioeconomic disadvantage was a significant predictor of insomnia and poor sleep quality, while it was associated with longer sleep duration. Significant heterogeneity in terms of exposure and outcomes, scarcity of longitudinal designs, lack of objective outcome measurement, and low representation of rural samples and participants from low-income countries limit the quality of evidence.

'Our mind could be our biggest challenge': A qualitative analysis of urban adolescents' sleep experiences and opportunities for mind-body integrative health approaches to improve sleep

Objective

To inform the development of a combined sleep and mind-body integrative health (MBIH) intervention, we explored urban adolescents' sleep experiences and perceptions of MBIH techniques.

Methods

We conducted eight focus groups with school-based health center patients in New York City, exploring sleep experiences; mindfulness, body awareness, tapping, acupressure, and self-hypnosis; and intervention delivery preferences. We recorded, transcribed, and analyzed the discussions applying methods from grounded theory.

Results

Participants (n = 25) were ages 14-17, predominantly female (64%), Latino (60%), and Black (40%). Participants reported social, physical, and internal sleep barriers, but had limited success implementing sleep improvement strategies. Participants viewed MBIH techniques positively, noted audio-guided techniques' accessibility, and were intrigued by less-familiar techniques. Preferences varied around domains of intervention delivery.

Conclusion

Results underscore the need for adolescent-informed interventions offering sleep improvement strategies. Participants' interest and willingness to engage in MBIH techniques present an opportunity for practitioners to develop and deliver sleep interventions incorporating MBIH components to urban adolescents. Varied intervention preferences highlight the need to be adaptable to adolescents' lived experiences, comfort levels, and learning styles.

Innovation

This study elucidates the perspectives of underrepresented adolescents whose perspectives on MBIH have rarely been explored, an important first step in developing tailored interventions.

Analysis, evaluation, and reformulation of social cognitive theory: Toward parent-child shared management in sleep health

THEORETICAL PRINCIPLES

Social Cognitive Theory (SCT) is a middle-range theory with triadic determinism between behavioral, environmental, and personal. SCT has been a guiding framework in health promotion research as it helps understand people's behaviors.

PHENOMENA ADDRESSED

Behavioral Insomnia of Childhood (BIC) is highly prevalent, affecting up to 45% of typically developing children and 80% of children with special healthcare needs. BIC leads to sleep deficiency, disrupted physical and psychological health, poor school performance, behavioral dysfunction, and negatively affects parental and family functioning. Using Fawcett's framework, we analyzed and evaluated SCT in a pediatric sleep context and propose a reformulation of SCT to better inform sleep research.

RESEARCH LINKAGES

SCT is individually focused and does not account for interdependence within relationships. Pediatric sleep interventions have limited long-term effects and sustainability without considering the parent-child dyadic interdependency. We advance the argument that the parent-child shared management (PCSM) perspective is beneficial for understanding pediatric sleep health. PCSM is a concept that reflects the shared responsibility and interdependence that parent and child have for managing child health. It assumes that with parents' ongoing support, children's responsibility for their health management increases over time, along with developmental progression and health-related experiences. We propose reformulating SCT by integrating PCSM in the pediatric sleep context: SCT with Shared Management (SCT-SM). The proposed SCT-SM accounts for parent-child interdependence and role transition. Shared management interventions that engage parents and children in active roles in managing sleep have potential sustainable effects in improving sleep and quality of life. (250).

Neighbourhood crime and obesity: Longitudinal evidence from Australia

RATIONALE

Obesity remains a significant public health concern globally with over one billion adults projected to be obese by 2025. To better understand the drivers of obesity and to inform policy, it is important to explore the factors that influence obesity.

OBJECTIVES

The objective of this paper to examine if the crime rates in the neighbourhood or local area in which a person lives influences their likelihood of being obese. Thus, we seek to contribute to the literature on the determinants of obesity by asking the question: what is the effect of neighbourhood (i.e., postcode) crime on obesity? We also examine the pathways through which neighbourhood crime influences obesity with a focus on the role of social capital, physical activity and sleep quality.

METHODS

Using 14 waves of longitudinal data from the Household, Income and Labour Dynamics in Australia (HILDA) survey merged with official police statistics on crime rates at the postcode level, we apply identification strategies that address endogeneity arising from endogenous sorting and omitted variable bias.

RESULTS

We find that an increase in neighbourhood crime rates is associated with an increase in body mass index (BMI) and the likelihood of being obese. Exploring the pathways through which neighbourhood crime influences obesity, we find that social capital and physical activity are important channels, while sleep quality is not. The evidence also suggests that the effects of violent crime are more pronounced compared to property crime.

CONCLUSION

Our findings suggest that targeting crime, and in particular violent crime, which seems to be driving the findings, is a core mechanism for reducing BMI and maintaining healthy body weight. The mediating role of physical activity and social capital also suggest that public policy can specifically target these areas by providing interventions that promote social capital and physical activity even amidst high crime rates.

Variation in Caregiver-Reported Child Sleep Patterns and Problems by Family Socioeconomic Indicators

OBJECTIVE

Previous studies of sleep patterns, as well as rates and correlates of perceived problems in early childhood, indicate variation by neighborhood-level socioeconomic indicators. The purpose of this study was to examine variation in (1) sleep patterns, behaviors, and problems by family-based socioeconomic indicators (income-to-needs ratio and caregiver education level) and (2) sociodemographic and sleep correlates of a caregiver-endorsed child sleep problem across and within socioeconomic indicator groups in a diverse sample.

METHODS

Two hundred eighty-three caregiver-child dyads (ages 1-5 years) completed the Brief Child Sleep Questionnaire. Family-level socioeconomic indicators included income-to-needs ratio and caregiver educational level.

RESULTS

Sleep patterns varied based on income-to-needs ratio, with children living in poverty experiencing the longest sleep onset latencies and night awakening durations and shortest nighttime sleep durations. Rates of an endorsed child sleep problem were similar across income-to-needs groups. Although sleep patterns did not vary by caregiver education level, caregivers with an education beyond high school were more likely to endorse a child sleep problem; later bedtimes, more frequent night awakenings, and greater bedtime difficulties were the strongest correlates of a perceived sleep problem in this subgroup. No specific correlates of a child sleep problem emerged for those with a high school education or less.

CONCLUSION

Sleep patterns may be more robustly linked to family income-to-needs ratio, whereas perceptions of a child sleep problem may be more linked to caregiver education level. Clinicians should consider expanding sleep screening questions to include specific sleep outcomes to effectively assess child sleep and guide intervention.

Examining the effects of cumulative environmental stressors on Gulf Coast child and adolescent health

This study examines how community-level cumulative environmental stress affects child and adolescent emotional distress and chronic health conditions both directly and indirectly through stressors at the household, family, and individual levels. Data comes from the Women and their Children's Health (WaTCH) Study, which sought to understand the health implications of exposure to the 2010 Deepwater Horizon oil spill (DHOS) among a cohort of 596 mothers with children ages 10 to 17 in southeastern Louisiana. Community-level environmental stress was measured using a newly developed geospatial index. Household-level stressors included previous hurricane impacts, impacts of DHOS, degree of financial difficulty, and degree of housing physical decay. Family stressors included maternal depression, self-rated physical health, and degree of parenting stress. Child stress was based on perceived stress; child mental health was based on serious emotional disturbance; and child physical health was based on diagnosis of chronic illness. Structural equation modeling used weighted least squares means and variance and theta parameterization. Results showed a significant negative direct path between community-level cumulative environmental stress and child/adolescent serious emotional disturbance and chronic illness. However, the indirect relationship through household, family, and individual-level stressors was significant and positive for both child/adolescent serious emotional disturbance and chronic illness. These findings point to the centrality of the household and family in determining child and adolescent physical and mental health outcomes in communities exposed to frequent disasters and ongoing environmental stressors.

Disparities in Sleep-Disordered Breathing: Upstream Risk Factors, Mechanisms, and Implications

Sleep-disordered breathing (SDB) refers to a spectrum of disorders ranging from habitual snoring without frank episodes of obstructed breathing or desaturation during sleep to obstructive sleep apnea, where apneas and hypopneas repetitively occur with resultant intermittent hypoxia, arousal, and sleep disruption. Disparities in SDB reflect its overall high prevalence in children and adults from racially and ethnically minoritized or low socioeconomic status backgrounds coupled with high rates of underdiagnosis and suboptimal treatment.

Neighborhood environment and adolescent sleep: The role of family socioeconomic status

OBJECTIVES

Socioeconomic status (SES) and neighborhood context are influential predictors of adolescent sleep, yet little is known about how they may interact to influence sleep. We examined multiple dimensions of family SES as moderators of associations between neighborhood risk and multiple sleep parameters.

METHODS

Participants were 323 adolescents (Mage = 17.4 years, SD = 0.86; 48% male; 60% White/European American, 40% Black/African American). Sleep was assessed using 7 nights of actigraphy from which sleep duration (minutes from onset to wake time), efficiency, long wake episodes, and variability in minutes over the week were derived. Youth reported on their sleep/wake problems and sleepiness, as well as their perceptions of safety and violence in their neighborhoods. Parents reported on SES indices, including income-to-needs ratio and perceived financial stability.

RESULTS

Lower SES (income-to-needs, perceived financial stability) was associated with lower sleep efficiency and more frequent long wake episodes. Lower neighborhood safety and greater community violence concerns were related to greater subjective sleep problems. Moderation effects illustrated two general patterns. For actigraphy-derived sleep variables, lower neighborhood safety was associated with poor sleep only among youth from lower-income families. For subjective sleep/wake problems and daytime sleepiness, associations between neighborhood risk and sleep difficulties were pronounced for higher SES youth, while lower SES youth had greater sleep problems regardless of neighborhood factors.

CONCLUSIONS

Findings suggest that several dimensions of SES and neighborhood risk may be consequential for adolescents' sleep. Moderation effects highlight the significance of considering multiple contextual influences towards a better understanding of adolescents' sleep.
