The present study aimed to examine the relation between pet ownership and sleep as well as moderators and mediators of this relation. Participants (N = 1256; 80.8% White; 50.5% men) residing in the United States completed an online survey which included assessment of sleep disturbances, physical activity, perceived stress, anxiety symptoms, and light exposure. Participants were categorised into one of four pet ownership groups: non-pet owners, cat-only owners, dog-only owners, and owners of both a dog and cat. Data analyses included analysis of covariance, moderation, parallel mediation, and conditional process modelling. Key findings included that pet ownership was significantly related to sleep, with non-pet owners sleeping worse than pet owners. Those that owned both a dog and cat reported the best sleep of all four pet ownership groups. The relation between pet ownership and sleep did not vary by gender. The relation was significantly mediated by anxiety symptoms, perceived stress, light exposure, and sleep-wake timing. Anxiety symptoms and perceived stress were the most robust mediators of the relation between pet ownership and sleep. Walking regularity did not moderate these effects. These pre-clinical findings provide a foundation for future research examining how the integration of pet ownership and sleep-promoting behaviours can improve adherence to sleep health recommendations, thus improving owners' sleep.</p>","PeriodicalId":17057,"journal":{"name":"Journal of Sleep Research","volume":" ","pages":"e70188"},"PeriodicalIF":3.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145023600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our primary aim was to characterise these 'sleepy insomniacs', and our secondary aim was to evaluate their response to this digital sleep intervention. Among 21,590 participants, individuals with an Epworth Sleepiness Scale score ≥ 11 and an Insomnia Severity Index score ≥ 15 were classified as 'sleepy insomniacs'. Comorbidities (i.e., obstructive sleep apnea syndrome, restless legs syndrome, depression, and sleep medication use) were first described and then excluded for further analyses. At baseline, 4843 (47.9%) of the 10,114 participants with insomnia also reported EDS and were categorised as 'sleepy insomniacs'. Half of this subgroup reported at least one comorbidity, with depression being the most common. After excluding participants with comorbidities, 3239 individuals (44.3%) remained in the 'sleepy insomniacs' category. These individuals were more likely to experience middle or late insomnia symptoms compared to those with insomnia without EDS but responded similarly to the digital sleep intervention. In conclusion, EDS is highly prevalent among individuals with insomnia symptoms. While comorbidities, particularly depression, explained the co-occurrence in approximately half of the sample, a substantial proportion of participants without comorbidities also exhibited this unexpected phenotype.

Therefore, our aim was to develop a CBTi intervention for adolescents with co-morbid mental health problems. This study utilised an iterative expert consultation approach to develop a CBTi intervention and define the appropriate target population, components and delivery. Eighteen experts were identified from literature searches and professional networks and invited to participate. Three iterative rounds of questionnaires were conducted and included both open-ended and closed-ended questions. In total, seven experts participated (R1 = 7, R2 = 5 and R3 = 1). In R1, four main themes emerged: (1) CBTi is appropriate for early-mid adolescents with anxiety/depression, (2) the proposed content and format were appropriate but required adaptation, (3) the proposed method of delivery was appropriate (i.e., in-person, by trained practitioner) and (4) parent/caregiver involvement is necessary. In R2, the intervention protocol was reviewed and finalised. In R3, the intervention materials were reviewed. The newly developed intervention comprises 4 weekly sessions, intervention materials and a training package for non-sleep experts.

First-time dispensing was defined as no use of hypnotics in the previous year and included benzodiazepines, benzodiazepine-related drugs, and melatonin receptor agonists. Data from 2020 were analysed across three periods: pre-lockdown (Weeks 1-11), lockdown (Weeks 12-19) and post-lockdown (Weeks 20-26), and were compared to the same periods in 2019. Analyses were stratified by age group (children: 0-9, adolescents: 10-19, adults: 20-64, elderly: 65+) and sex. The data revealed a significant reduction in first-time hypnotic dispensations in 2020 (155,961) compared to 2019 (168,814, p < 0.001), with declines across all three time periods (p < 0.001).

These statements were submitted to a panel of 37 GPs across France via two rounds of anonymous rating using a 9-point Likert scale. While a consensus was reached for 95% of the statements, encompassing initial evaluation, sleep hygiene recommendations, behavioural interventions, and referral criteria, controversies emerged regarding the prescription of hypnotics, underscoring areas requiring further clarification and education.

To test the hypothesis, we employed a comprehensive translational approach consisting of an innovative IH system for cell cultures, a murine IH model of diet-induced obese mice and a proof-of-concept randomised-controlled study in OSA (NCT04186494).

Four hundred and seven school-aged children with OSAS (age 6.5 ± 1.4 years; 51.4% female, 92.1% non-Hispanic or Latino) were included in this study from the Childhood Adenotonsillectomy Trial (CHAT) study database. For the analysis, general linear models and linear regression were tested for sleep quality outcomes using polysomnographic data at follow-up (7 months) including: wake after sleep onset, sleep efficiency, sleep latency and total sleep duration and anthropometric markers at baseline including: waist circumference, neck circumference and obesity (body mass index percentile ≥ 95). Children with obesity had lower sleep efficiency (p = 0.021) and higher sleep latency (p = 0.049) than children without obesity.
