Sleep Health最新文献

Objectives: Adolescent sleep is linked to indices of health and well-being, including academic performance, physical health, mood, and safety. However, biological, psychological, and social changes make it difficult for adolescents to obtain enough quality sleep. As a result, the percentage of adolescents who achieve optimal sleep has steadily diminished for decades. Reversing this trajectory requires a multipronged approach and involvement from numerous stakeholders, including adolescents themselves. To support this need, the National Sleep Foundation sponsored a multidisciplinary Adolescent Sleep Health Conference to identify recommendations to improve adolescent sleep health in the United States and beyond.

Methods: The 2022 Adolescent Sleep Health Conference convened 22 experts (educators, administrators, parents, advocates, researchers, clinicians, and an adolescent representative) to discuss evidence related to adolescent sleep health and its intersections with health, education, athletics, transportation, and the workforce. Final recommendations reflect those generated during the Conference and additional post hoc recommendations informed by extant literature.

Results: Factors influencing adolescent sleep are present at individual, social, and societal levels. Societal factors such as school start times, entering the workforce, driving, and clock changes are linked to adolescent sleep. Improving adolescent sleep health involves integrating developmental science, family, and educational contexts into sleep health recommendations, implementing healthy school start times and adopting permanent standard time, increasing awareness of the impact on work and driving, and prioritizing sleep health equity.

Conclusions: Policy changes and prioritization across settings can increase the opportunity and likelihood of healthy sleep. Adolescents must be included as contributors to improving sleep health.

Background: While studies have shown that non-Latinx Black and Latinx adults sleep less and more poorly than non-Latinx White adults, the cognitive consequences of poor sleep in non-Latinx Black and Latinx adults are understudied. We hypothesized that poorer quality sleep and short or long sleep durations are associated with poorer memory performance, and the strength of these associations differs by racial and ethnic group.

Method: Our analysis included non-Latinx Black, non-Latinx White, and Latinx participants across the adult lifespan recruited from the community of Northern Manhattan as a part of the Offspring study. Participants self-reported their sleep duration and quality using the Pittsburgh Sleep Quality Index. We evaluated memory with the Buschke Selective Reminding Task. We used multivariable regression to estimate associations between sleep duration and quality with delayed recall.

Results: In the overall sample, higher quality sleep was associated with better delayed recall performance. We also found linear and quadratic relationships between sleep duration and delayed recall. Taken together, higher quality sleep and adequate sleep duration were linked with better delayed recall. Stratified analyses revealed that these effects were strongest in the Latinx group but were not present among non-Latinx Black and non-Latinx White participants.

Conclusion: We observed associations between poor sleep quality and sleep duration and memory performance in Latinx adults. Future work will determine which psychosocial factors (e.g., social support, discrimination) underlie racial and ethnic sleep disparities and mediate racial and ethnic differences in the cognitive consequences of poor sleep.

This systematic review summarizes literature relating to 3 questions of interest: (RQ1) Is partner disturbance a common phenomenon in the sleep of healthy populations? (RQ2) What is the effect of co-sleeping on sleep architecture? (RQ3) What factors moderate the effect of co-sleeping on sleep architecture? Google scholar, Scopus, NCBI, Web of Science, Cochrane Library, and PsychInfo were searched on 7 September 2025, for articles relating to each research question. Risk of bias was assessed by first author using NOS-xs tool (Carra et al., 2025). Results relating to movement concordance, sleep architecture, and continuity metrics are reported, including percentage increase across groups. All 4 studies relating to RQ1 find evidence of partner disturbance. Two of 3 studies relating to RQ2 found increased REM duration in co-sleep compared to individual sleep. Eleven studies relating to RQ3 explored factors influencing sleep architecture in co-sleep, including presence of partner with sleep disordered breathing (SDB), insomnia, and interpersonal social factors. Overall, limitations of RQ1 studies include inconsistency in actigraphy measurement, including device used, sensitivity, and activity threshold algorithm and epoch length, as well as lack of control or measurement of disturbances outside of the couple. RQ2 was hampered by a small sample size investigating differences in sleep architecture between co-sleep and alone sleep, and lack of measurement of mediating factors. In RQ3, heterogeneity in studies and design protocol hamper interpretation of findings. This review summarizes literature relating to co-sleep effects on sleep architecture and finds that no single mechanism entirely explains net effects on sleep architecture.

Objectives: This study sought to bolster current understanding of population-level impact of large-scale societal events through examination of reported sleep disruption surrounding the 2024 U.S. presidential election and demographic factors associated with these disruptions.

Methods: Data collected by National Sleep Foundation from a nationally representative random sample of 991 U.S. adults were analyzed. The study survey included questions on election-related sleep disruptions, sleep quality, and sleep duration. The results were compared to a previously analyzed nationally representative random sample (N = 1364) that examined the same trends prior to the election.

Results: In the immediate aftermath of the 2024 U.S. presidential election, 17% of U.S. adults endorsed experiencing a negative impact on their sleep. Significant group differences were found based on political affiliation, education, and other demographics, and differences between pre- and post-election samples were observed, with significantly less Republican (χ² = 39.12, p < .001) and Independent (χ² = 5.59, p = .02) individuals and significantly more Democrat-affiliated individuals (χ² = 22.54, p < .001) reporting post-election.

Conclusions: Following the 2024 U.S. presidential election, a significant number of U.S. adults reported a negative impact on their sleep health. These results were consistent with other investigations that showed the effects of stressful, large-scale societal events on sleep. These negative impacts were particularly observed in specific sub-populations. Future studies and public health action are needed to better understand and address disruptions to sleep and sleep health that can accompany major sociopolitical events.
