There is limited education or early intervention to encourage awareness of, and treatment for, sleep disorders in young adults who will transition into careers requiring shift work. This study aims to investigate (a) the <i>clinical effectiveness</i> of simulated shift work exposure and cognitive performance feedback for prompting help-seeking for sleep problems, and (b) the feasibility and acceptability of <i>implementing</i> this intervention for future healthcare workers. A hybrid type I effectiveness-implementation trial will be conducted from June 2024 to December 2025 with prospective healthcare workers currently enrolled in a medicine, paramedicine, or nursing degree. Ninety adults (18-39 years) who self-report sleep disturbances will be recruited and complete a combination of structured clinical interviews, screening questionnaires, remote monitoring technology, and overnight polysomnography (PSG). Participants will be randomized across three conditions, with varying exposure to a simulated transition to night shift without sleep, and cognitive performance feedback. All individuals will attend a diagnostic appointment with a sleep psychologist or sleep physician and discuss help-seeking pathways for their sleep. The primary outcomes will be help-seeking from a health professional for sleep (yes/no), time to help-seeking (days), and road safety-related events over 12 months. Process evaluation will explore the feasibility and acceptability of this approach from the participants' perspective.</p>","PeriodicalId":74808,"journal":{"name":"Sleep advances : a journal of the Sleep Research Society","volume":"6 2","pages":"zpaf020"},"PeriodicalIF":0.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12062959/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144002158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sleep reinforces skills acquired during the day and is associated with the occurrence of specific oscillations such as spindles. However, with age, spindles deteriorate and thus likely contribute to memory impairments observed in older adults. The application of electric currents by means of transcranial alternating current stimulation (tACS) with spindle-like waveform, applied during the night, was found to enhance spindles and motor memory consolidation in young adults. Here, we tested whether tACS bursts inspired by spindles applied during daytime naps may (i) increase spindle density and (ii) foster motor memory consolidation in older adults. Twenty-six healthy older participants performed a force modulation task at 10:00, were retested at 16:30, and the day after the initial training. They had 90-minute opportunity to take a nap while verum or placebo spindle-inspired tACS bursts were applied with similar temporal parameters to those observed in young adults and independently of natural spindles, which are reduced in the elderly. We show that the density of natural spindles correlates with the magnitude of memory consolidation, thus confirming that spindles are promising physiological targets for enhancing memory consolidation in older adults. However, spindle-inspired tACS, as used in the present study, did not enhance either spindles or memory consolidation. We therefore suggest that applying tACS time-locked to natural spindles might be required to entrain them and improve their related functions.</p>","PeriodicalId":74808,"journal":{"name":"Sleep advances : a journal of the Sleep Research Society","volume":"6 2","pages":"zpaf022"},"PeriodicalIF":0.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12070486/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144002009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data from the Adolescent Brain Cognitive Development (ABCD) study were analyzed using <i>t</i>-tests and structural equation modeling (SEM) to assess behavioral, social, and psychological predictors of chronotype, social jet lag, and weekday sleep duration, incorporating demographic covariates. Hispanic adolescents exhibited a later chronotype (Cohen's <i>d</i> = 0.42), greater social jet lag (Cohen's <i>d</i> = 0.38), and shorter weekday sleep duration (Cohen's <i>d</i> = -0.12) compared to non-Hispanic peers.

Screen time was more prevalent among Hispanic adolescents, particularly on weekday evenings (Cohen's <i>d</i> = 0.27) and weekend evenings (Cohen's <i>d</i> = 0.35), and was strongly associated with later chronotype and greater social jet lag. Higher perceived stress was linked to later chronotype and greater social jet lag, while depressive symptoms were associated with earlier chronotype and lower social jet lag. The SEM model explained 12.9% of variance in chronotype, 10.5% in social jet lag, and 6.2% in weekday sleep duration. These findings highlight disparities in adolescent sleep health but should be interpreted cautiously due to methodological limitations, including low caffeine use and assessment timing variability.
