Objectives: To investigate potential sleep inequities between the infants of Māori and non-Māori mothers in Aotearoa New Zealand, identify socio-ecological factors associated with infant sleep, and determine features of infant sleep that contribute to a mother-perceived infant sleep problem.

Design: Secondary analysis of longitudinal data from the Moe Kura: Mother and Child, Sleep and Well-being in Aotearoa New Zealand study when infants were approximately 12 weeks old.

Participants: 383 Māori and 702 non-Māori mother-infant dyads.

Methods: Chi-square and independent t-tests measured bivariate associations between maternal ethnicity and infant sleep characteristics. Multivariable and ordinal logistic regression models assessed the relative impact of different socio-ecological factors on infant sleep outcome variables.

Results: Key developmental markers of infant sleep did not differ by maternal ethnicity. There were some ethnicity-based differences in sleep location. Maternal ethnicity, maternal age, parity, maternal depression, maternal relationship status, life stress, breastfeeding, work status, and bedsharing were related to different dimensions of infant sleep, and to maternal perceptions of a sleep problem.

Conclusion: Sleep at 12weeks is highly variable between infants and is associated with numerous socio-ecological factors. Findings support a social determinants explanation for sleep health inequities seen later in childhood.

Objectives: To describe sleep duration, adherence to sleep recommendations, and behavioral and sociodemographic correlates of sleep among Samoan children.

Methods: In a longitudinal cohort study of Samoan children aged 2-9years (n = 481; 50% female), primary caregivers reported usual number of hours of nighttime sleep during 2015, 2017/2018, and 2019/2020 data collection waves. Associations between behavioral and sociodemographic characteristics and sleep duration were assessed using generalized linear and mixed effect regressions.

Results: Average reported hours of nighttime sleep for toddlers (age 2) was 9.7 ± 1.1 (SD); for preschoolers (age 3-5) 9.5 ± 1.0, and for school-age children (age 6-9) 9.4 ± 1.3, with 58% of children meeting sleep recommendations. Living in a lower income household was associated with 30 more minutes of sleep for toddlers (adjusted β:0.56 [95% CI: 0.03, 1.09]) and preschoolers (adjusted β:0.51 [95% CI: 0.17, 0.85]), while higher reported physical activity was associated with longer sleep for school-age children (adjusted β:0.49 [95% CI: 0.08, 0.91]). Preschoolers with a primary caregiver who did not complete high school had shorter sleep (β: -0.80 [95% CI: -1.12, -0.48]). Among school-aged children, shorter sleep was associated with greater total carbohydrate intake (for every 100 g/day, β: -0.01 [95% CI: -0.02, 0.01]) and neotraditional dietary pattern adherence (β: -0.27 [95% CI: -0.53, -0.01]).

Conclusions: Efforts should be made to encourage adequate sleep among Samoan children. Correlates of sleep were largely consistent with existing literature. Future research should examine additional culturally and contextually-specific risk factors for insufficient sleep in Samoa and consequences for child health.

Objectives: People with idiopathic hypersomnia report significant impairment in their lives due to idiopathic hypersomnia symptoms, and this likely includes an impact on social relationship health. This study investigated the effects of idiopathic hypersomnia on social relationships (friends, romantic, and sexual) during the key developmental period of young adulthood.

Methods: Young adults (N = 106; 18-39years) with idiopathic hypersomnia were recruited through national hypersomnia patient organizations. Participants completed an online survey assessing the impact of symptoms on overall social functioning, as well as assessing friendships, romantic relationships, and sexual relationships.

Results: Nearly all participants (98%) reported that idiopathic hypersomnia made their social life more challenging. Over half (56%) felt they had too few close friends. While 69% were currently in a romantic relationship, the majority (92%) reported that idiopathic hypersomnia made it more challenging to enter a romantic relationship, with 89% stating that it impacted their sex life. Symptoms with the greatest perceived impact on social relationships were excessive sleepiness, brain fog, and long sleep. Most participants expressed that they would like their clinicians to ask about their social lives.

Conclusions: Idiopathic hypersomnia substantially impacts the social lives of young adults, including friendships, romantic partnerships, and sex lives. Despite the importance of social relationships, clinicians seldom address this topic during clinic visits. When considering whole person health for people with idiopathic hypersomnia, clinical care would benefit from more attention to social health.

Objective: Our objective was to investigate the associations of sleep duration and weekend catch-up sleep with cancer risk among US adults in the Cancer Prevention Study-3.

Methods: Cancer Prevention Study-3 is a prospective cohort of approximately 250,000 US adults aged 30-65years. At baseline (2006-2013), participants were asked to report their average daily sleep duration over the past year for weekdays and weekends separately. Using the midpoint of each sleep duration category, a 5:2 weekday:weekend weighted average was created. Weekend catch-up sleep was calculated using the difference of weekend and weekday sleep duration category midpoints and categorized as -4 or -2, 0, 2, and 4 hours. Cancer incidence (overall and female breast) was determined via linkage to state registries; follow-up time ended at the time of cancer diagnosis, time of death, or end of follow-up (12/31/2018). We used multivariable Cox proportional hazards models to estimate adjusted hazard ratios and 95% confidence intervals for the associations of sleep duration and weekend catch-up sleep with cancer risk adjusted for sociodemographics, socioeconomic status, comorbidities, and lifestyle behaviors.

Results: A total of 10,256 incident cancer cases were reported among the 248,086 participants included in the study. We found no statistically significant associations between the examined sleep characteristics with overall or breast cancer-specific risk.

Conclusion: Our research strengthens the existing null findings of the association between sleep duration and cancer risk. This was the first study to investigate the relationship of weekend catch-up sleep with cancer risk and more research is necessary to further elucidate this relationship.

Objectives: Health literacy includes the skills necessary for effective communication with health professionals, understanding health instructions, and recognizing health needs. Our study aimed to create a novel measure of sleep health literacy-an individual's capacity to comprehend sleep-related information and navigate sleep-related healthcare services.

Methods: The Sleep Health Literacy scale consists of two subscales: "Sleep Health Communication" (11 Likert-scale items assessing access to resources and communication with healthcare providers) and "Sleep Health Knowledge" (46 true/false items assessing specific knowledge of sleep health). The Sleep Health Literacy scale was completed by 154 undergraduate students (mean age=20.96years; 79.87% female) in study 1. In study 2, an additional sample of 251 participants (mean age=20.23years; 79.87% female) completed the Sleep Health Literacy scale, along with measures of convergent and discriminant validity.

Results: Exploratory factor analysis results in study 1 revealed a two-factor structure for the "Sleep Health Communication" subscale ("comprehension" and "critical application"). The subscale demonstrated good internal consistency (α = 0.81) and inter-item and item-total correlations. On the "Sleep Health Knowledge" subscale, participants answered 76.36% of items correctly. In study 2, the Sleep Health Literacy had good convergent validity with Sleep Beliefs Scale and the All Aspect of Health Literacy Scale.

Conclusions: The Sleep Health Literacy scale offers a standardized measure to assess sleep health literacy, an understudied domain that has important links to health. This measure may allow researchers and clinicians to better understand how to improve sleep health. Further validation of the Sleep Health Literacy scale is warranted in more diverse samples.

Objectives: Sleep is important for adolescent health. The unique needs of suprabinary youth (youth with gender identities outside of the gender binary), along with the growing number of youth with these identities, underscores the need to better understand sleep health within this population. The current study's objectives were to (1) examine differences in sleep health between suprabinary and binary youth and (2) explore how social support, peer victimization, and technology use accounted for these differences.

Methods: Data were drawn from the 2017/2018 Health Behavior in School Aged Children Survey. Adolescents (individuals ages 14 to 17, n = 10,186), indicated whether they were suprabinary (n = 182) or binary (n = 10,004), and completed measures of sleep health (difficulty falling asleep, difficulty staying awake, weekday and weekend sleep length), covariates (age, family affluence, race/ethnicity, depressive symptoms), as well as variables that may account for differences between suprabinary and binary youth (family, friend, and teacher support, as well as peer victimization, and technology use before bed).

Results: Suprabinary youth reported worse sleep health on all outcomes, and differences persisted for both difficulty falling asleep and weekday sleep hours accounting for covariates. Significant indirect effects between suprabinary status were observed across all sleep outcomes for family support and school climate. Indirect effects for sleep quality were also observed via peer victimization.

Conclusions: Findings support the relevance of looking at basic health processes like sleep to better understand how the stressors associated with suprabinary status impact health outcomes among this vulnerable population.

Objectives: The present study aimed at exploring the association between eveningness and lifestyle-related variables, that is, body mass index, alcohol, and cigarette consumption, in adults (18-40years), focusing on the possible moderator effect of age and the role of sleep disturbances and circadian misalignment (social jetlag).

Methods: A web-based survey was administered to 437 participants, covering demographics, lifestyle-related variables, chronotype, sleep quality, and daytime sleepiness. A subset of 206 participants wore a wrist actigraph for a week, allowing the creation of a sleep health index within the RU-SATED framework. Regression analysis was used to investigate the associations between chronotype and lifestyle-related outcomes, accounting for social jetlag and sleep health; and to explore the lifestyle trajectories over time.

Results: Evening chronotypes showed higher body mass index levels, consumed more alcohol, and smoked more cigarettes than other circadian typologies, in particular after 25 years of age. Poor sleep health and social jetlag significantly contribute to explaining evening types smoking behavior, while not affecting body mass index levels. Social jetlag plays a more important role compared to sleep disturbances and eveningness in predicting more detrimental drinking and smoking behavior.

Conclusions: Participants who maintain the evening trait past the age of 25years are more prone to adopt an unhealthy lifestyle, especially if experiencing poor sleep health and circadian misalignment. Circadian preferences and sleep health should be considered when planning interventions aimed at promoting healthy lifestyles in adults aged 18-40years. Further investigations should explore the effect of modifications in lifestyle in the prevention of noncommunicable diseases.

Objectives: This study investigated the associations between specific sleep health characteristics and indicators of positive mental health among Canadian youth in grades 6-10.

Methods: We used cross-sectional data from the Canadian 2017/2018 Health Behaviour in School-aged Children study, a nationally representative sample of Canadian students. Our analyses included 14,868 participants (53.1% girls). We assessed the following self-reported characteristics of sleep health: nighttime insomnia symptoms, sleep duration, problems with daytime wakefulness, and weekend catch-up sleep. Positive mental health measures included self-reported life satisfaction, positive affect, self-efficacy, and self-confidence. Logistic regression models were used to assess associations while controlling for confounders.

Results: Participants who had no or little nighttime insomnia symptoms, who met sleep duration recommendations, who had no or rare daytime wakefulness problems, and who had no or little weekend catch-up sleep were more likely to report high life satisfaction (range of adjusted odds ratios=1.29-2.50), high positive affect (range of adjusted odds ratios=1.35-3.60), high self-efficacy (range of adjusted odds ratios=1.22-2.54), and high self-confidence (range of adjusted odds ratios=1.28-2.31). Almost all of the associations remained significant in the gender- and age-stratified analyses.

Conclusion: The findings suggest that good sleep health is associated with higher odds of positive mental health among Canadian youth in grades 6-10. Further research is needed to understand the temporality of the associations and the underlying mechanisms.
