Validation of intrinsic capacity and healthy sleep pattern in middle-aged and older adults: a longitudinal Chinese study assessing healthy ageing

ObjectivesIntrinsic capacity (IC), a multidimensional construct encompassing mental and physical capacities, has been established in the aging framework by the World Health Organization. However, the detailed relationship between IC and Chinese sleep patterns (nighttime sleep and post-lunch naps) remains inadequately elucidated. MethodsParticipants in this study were individuals aged ≥45 years residing in China, included in the China Health and Retirement Longitudinal Study (CHARLS). We analyzed 4 years of CHARLS data from the first wave (May 2011–March 2012) to the second wave (July 2015–January 2016). Data from these waves were utilized for longitudinal analysis. Self-reported data included nighttime sleep and nap duration, along with other baseline characteristics. The IC evaluation involved physical examinations and blood tests. Initially, linear regression was used to assess the relationship between total sleep duration, nighttime sleep duration, nap duration, and IC change between the two waves that were determined by marginal effects (ME) and their corresponding 95% confidence intervals (CIs). Regression splines were employed to explore potential nonlinear associations. Subgroup and sensitivity analyses were conducted to investigate the heterogeneity of IC change under specific conditions and the robustness of our results. Mediation analysis was performed to identify potential factors mediating the relationship between sleep patterns and IC change. ResultsBoth excessive (>10 h) (total, ME: −1.12; 95% CI: −1.61, −0.64; nighttime, ME: −1.44; 95% CI: −2.29, −0.59) and insufficient (<6 h) sleep duration (total, ME: −0.43; 95% CI: −0.68, −0.18; nighttime, ME: −0.50; 95% CI: −0.73, −0.27) negatively impacted IC change. Moderate naps (≤60 min) mitigated the decline in IC change (ME: 0.28; 95% CI: 0.07, 0.49). IC values decreased at the slowest rate when nap time constituted one-seventh of total sleep time. The onset of dyslipidemia partially mediated the association between naps (≤60 min) and IC change (P = 0.02). ConclusionsThese findings suggest that maintaining a healthy sleep pattern of 6−8 h of nighttime or total sleep, along with a post-lunch nap of ≤60 min, helps preserve optimal IC or delay its decline. This is particularly beneficial for cognitive, psychological, and locomotion performance among middle-aged and older adults.

Sleep Characteristics of Patients Admitted to Intensive Care Units after Major Abdominal Surgery

Purpose : The aim of this study was to investigate sleep parameters and architecture in patients admitted to the intensive care unit (ICU) on the day of abdominal surgery. Methods : A total of ten patients who underwent laparotomy under general anesthesia at the hepatopancreatobiliary surgery department of a general hospital in Busan, South Korea participated in this observational study. We measured total sleep time (TST), sleep efficiency (SE), wake after sleep onset (WASO), and sleep stages on their first night in the ICU using the WatchPAT300. Furthermore, we used nonparametric statistics to examine differences in postoperative sleep based on sedative administration. Results : The Median (IQR) TST for the participants was 399.50(263.80) minutes; the SE was 75.1 (30.4)%; the WASO rate was 27.8(30.6)%; and the WASO frequency was 5.50(8.50) times. Patients’ rapid eye movement (REM) sleep time was 114.31(87.88) minutes, with 55.8(11.9)% of N1, 18.2(5.3)% of N2, and 24.8 (11.7)% of N3 sleep stages. The sedation group had a longer TST (Z=-2.619, &lt;i&gt;p&lt;/i&gt; =.008), higher SE (Z=-2.611, &lt;i&gt;p&lt;/i&gt; =.008), lower WASO rate (Z=-2.611, &lt;i&gt;p&lt;/i&gt; =.008), smaller number of WASOs (Z=-2.627, &lt;i&gt;p&lt;/i&gt; =.008), and longer REM sleep (Z=-2.617, &lt;i&gt;p&lt;/i&gt; =.008) compared to the non-sedation group. Conclusion : We observed a high rate of light sleep and awakenings during sleep in patients admitted to the ICU after surgery. Moreover, non-sedated patients lacked either deep or REM sleep. Sleep-improving interventions are needed for non-sedated surgical patients who are admitted to the ICU.

Maternal depressive symptoms in and beyond the perinatal period: Associations with infant and preschooler sleep.

(1) To describe sleep in infancy and early childhood among children born to mothers with and without clinically significant depressive symptoms, and (2) to explore the relationships between maternal depressive symptoms and sleep patterns and problems during infancy and early childhood. Secondary analysis of longitudinal data from the Moe Kura: Mother and Child, Sleep and Wellbeing in Aotearoa/New Zealand study. Data was collected in pregnancy (T1), 12 weeks postpartum (T2), and 3 years post-birth (T3). Participants were 262 Māori and 594 non-Māori mother-child dyads. Chi-square and Independent T-tests measured bivariate associations between maternal mood (T1, T2, T3) and child sleep characteristics (T2, T3). Binary logistic regression models examined longitudinal and concurrent associations between maternal depressive symptoms and infant and preschooler sleep. Adjusted models accounted for key socio-demographic variables, as well as infant sleep variables in preschooler models. Bivariate associations were found between prior and concurrent depressive symptomology and many of the infant and preschooler sleep outcomes. In adjusted models, prenatal depressive symptoms remained independently associated with shorter-than-recommended sleep durations in preschoolers. In these models, concurrent depression was also associated with night waking, night LSRSP, and perceived sleep problems at 12 weeks postpartum, and CSHQ-determined and perceived sleep problems at 3 years post birth. Longitudinal and cross-sectional associations were found between maternal depressive symptoms and child sleep. Sleep appears to be one pathway by which maternal depression confers risk for suboptimal child health outcomes. Findings support the need for earlier and better maternal mental health services.

Longitudinal associations between accelerometry-assessed sleep clusters and obesity in adolescence and young adulthood: the German GINIplus and LISA birth cohorts study

Abstract Background Some studies have identified diverse sleep patterns in adolescents and adults by considering multidimensional objective sleep parameters. However, whether sleep patterns are consistent from adolescence to young adulthood and their long-term associations with obesity remain unknown. Purpose This study aimed to investigate the longitudinal associations of objectively measured and clustering-identified sleep patterns with body mass index (BMI) and overweight/obesity in adolescence and young adulthood, and to test whether these associations change over time or are modified by genetic risk. Methods A total of 1973 participants wearing 7-day accelerometers in either 15-year (n=1347, aged 14.3-16.4 years) and/or 20-year (n=1262, aged 19.5-22.4 years) follow-ups of German GINIplus and LISA birth cohorts were included. Sleep clusters were identified by K-means cluster analysis on 12 accelerometry-assessed sleep characteristics at each follow-up. BMI and overweight/obesity were measured by physical exams or self-/parent-reported questionnaires. Multivariable linear and logistic regression models with generalized estimating equations were tested. The interaction effects with time of follow-ups and polygenic risk scores (PRS, n=1087) for BMI were further examined. Results Although sleep characteristics changed from adolescence to young adulthood, such as shorter total sleep time (mean 7.2 to 6.6 hours), the consistent five sleep clusters were classified in both periods: good sleep, delayed sleep phase, sleep irregularity and variability, fragmented sleep, and prolonged sleep latency. Compared to the "good sleep" cluster, the "prolonged sleep latency" cluster showed significant associations with higher BMI (β=0.56, 95% confidence interval (CI) = [0.06, 1.05]) and increased odds of overweight/obesity (odds ratio (OR)=1.55, 95%CI= [1.02, 2.34]). PRS was associated with higher BMI (β=0.65, 95%CI= [0.39, 0.91]) and overweight/obesity (OR=1.52, 95%CI= [1.15, 2.00]), with no significant gene-sleep cluster interaction effect. Only among males, the interaction effects with time of follow-ups on overweight/obesity were observed in the "delayed sleep phase", "sleep irregularity and variability", and "fragmented sleep" clusters (p-interaction &amp;lt;0.05), showing more harmful effects with increasing age. Conclusions Five sleep patterns were identified consistently across adolescence and young adulthood, and the "prolonged sleep latency" pattern was associated with higher BMI and overweight/obesity, independent of genetic risk. For young adult males, "delayed sleep phase", "sleep irregularity and variability" and "fragmented sleep" patterns seemed to have more unfavorable impacts on overweight/obesity.

A cross-sectional study on health behavior changes during COVID-19 among adults in Malaysia

IntroductionCOVID-19 has triggered significant disruptions globally, necessitating swift adaptations in individuals’ health behaviors.MethodsThis cross-sectional study was conducted during Phase Four of Malaysia’s National Recovery Plan and examines how the pandemic has affected health behaviors among adult Malaysians. The study gathered data online using convenience sampling with 1,004 respondents aged 18 and above. The research focused on diverse health domains, including eating habits, physical activity, smoking, alcohol consumption, and sleep patterns. The Wilcoxon Signed Rank test and descriptive statistics were employed to compare health behaviors before and after COVID-19.ResultsFindings indicate noteworthy shifts in eating behaviors, with increased water and fruit consumption (p &amp;lt; .001). The frequency of home-cooked meals stayed relatively stable despite declining dinner preference and increasing daily snacks. Physical activity declined, marked by increased sedentary behavior and screen time (p &amp;lt; .001). There were differences in the patterns of smoking and alcohol consumption; some had started these behaviors during the pandemic. Notably, intentions to quit smoking among respondents were more prominent than attempts to stop drinking. Respondents’ sleep patterns also changed, with more sleeping fewer than seven hours daily (p &amp;lt; .001).ConclusionThe study emphasizes the need for focused interventions to address new challenges by highlighting the impact on health behaviors. As Malaysia navigates the post-pandemic landscape, understanding and mitigating the persisting effects on health behaviors are crucial for promoting overall well-being.

Association of weekday-to-weekend sleep duration pattern with myocardial infarction: analysis of the NHANES 2017- 2020

Abstract Background Short sleep is linked to increased acute myocardial infarction (MI) risk.However, the association of weekend-to-weekday sleep patterns with MI in a nationally representative population remains unknown. The goal is to investigate how weekday and weekend sleep durations affect myocardial infarction (MI) in the general population, and if longer weekend sleep can offset insufficient weekday sleep's effects. Methods A cross-sectional study utilized data from the 2017-2020 NHANES to examine the relationship between sleep patterns and MI. Participants self-reported their average sleep durations on weekdays (1) and weekends (2), along with the calculated weekend-to-weekday sleep duration ratio (SDR) (3). Logistic regression models, adjusting for various factors, including demographics and comorbidities, were employed to analyze the association. Those with SDR &amp;gt; 1 had more weekend sleep, while an SDR = 1 indicated equal sleep durations. Results The study involved 9,205 adult participants, with a mean ± SD age of 68.8 ± 10.8 years and 30.7% being female. Among them, 4.65% (428 patients) had a history of MI. The mean ± SD of weekday and weekend sleep hours was 7.6 ± 1.7 and 8.3 ± 1.8 hours, respectively. For weekday sleep duration, after univariate analysis, individuals compared to those in Q1 were statistically significant 0.72 times less likely in Q2 and 1.4 times more likely in Q4 to experience MI . While MI was 0.76 times less likely to occur among participants in Q3, it was not statistically significant (95% CI Q2: 0.54, 0.96; Q4: 1.05, 1.76; Q3:0.57, 1.00). After adjusting, participants only in Q3 were statistically significant 0.71 times less likely to develop MI.(Q3: 95% CI 0.51, 0.99). For weekend sleep duration, the univariate analysis showed that individuals in Q2, Q3, and Q4 were significantly less likely to experience MI (OR = 0.63, 0.67, and 0.69; 95% CIs: 0.48-0.82, 0.51-0.87, 0.53-0.90, respectively) After adjusting, only participants in Q2 were statistically significant less likely to develop MI (OR = 0.71; 95% CI 0.52 - 0.96). For the weekend-to-weekday sleep duration ratio (SDR), after univariate analysis, individuals were statistically significant 0.54 times less likely, and 1.5 times more likely to experience MI in those whose SDR is more than 1, and those whose SDR equals 1, respectively (95% CI SDR &amp;gt; 1: 1.14, 1.98; SDR = 1: 0.39, 0.72). After adjusting, participants with SDR more than 1 were statistically significant 0.69 times less likely to develop MI. Conclusions Moderate sleep durations on weekdays (in Q3), weekends (in Q2), along with SDR more than 1, were negatively linked with MI in a general population. This implies that sleep durations on both weekends and weekdays have comparable associations with MI. Additionally, full recovery sleep on weekends following sleep-deprived weekdays, might reduce MI risk. Further studies are needed to explore impact of weekend and weekday sleep patterns on MI.Histogram and Margins plotTable of Odd ratios

Sex differences in sleep deficits in mice with an autism-linked Shank3 mutation

BackgroundInsomnia is more prevalent in individuals with Autism Spectrum Disorder (ASD), can worsen core-symptoms and reduces quality of life of both individuals and caregivers. Although ASD is four times more prevalent in males than females, less is known about sex specific sleep differences in autistic individuals. Recent ASD studies suggest that sleep problems may be more severe in females, which aligns with the sex bias seen in insomnia for the general population. We have previously shown that male mice with a mutation in the high confidence ASD gene Shank3, Shank3∆C, recapitulate most aspects of the ASD insomnia phenotype. The objective of the present study was to leverage the Shank3∆C model to investigate sex-specific effects in sleep using polysomnography.MethodsAdult male and female Shank3∆C and wildtype (WT) littermates were first recorded for 24 h of baseline recordings. Subsequently, they were sleep deprived (SD) for five hours via gentle handling and allowed 19 h of recovery sleep to characterize the homeostatic response to SD. Vigilance states (rapid eye movement (REM) sleep, non-rapid eye movement (NREM) sleep and wake) were assigned by manual inspection using SleepSign. Data processing, statistical analysis and visualization were conducted using MATLAB.ResultsSex and genotype effects were found during baseline sleep and after SD. At baseline, male Shank3∆C mice sleep less during the dark period (active phase) while female Shank3∆C mice sleep less during the light period (rest phase) and sleep more during the dark period. Both male and female Shank3∆C mice show reduced spectral power in NREM sleep. We detect a significant effect of sex and genotype in sleep onset latency and homeostatic sleep pressure (sleepiness). In addition, while male Shank3∆C mice fail to increase sleep time following SD as seen in WT, female Shank3∆C mice decrease sleep time.ConclusionsOverall, our study demonstrates sex differences in sleep architecture and homeostatic response to SD in adult Shank3∆C mice. Thus, our study demonstrates an interaction between sex and genotype in Shank3∆C mice and supports the use of the Shank3∆C model to better understand mechanisms contributing to the sex differences in insomnia in ASD in clinical populations.

Sleep pattern, behavior, duration and incident hypertension: results from two large prospective cohorts

Abstract Background Poor sleep quality pose significant public health challenges globally. The objective of this study is to investigate the association between sleep quality, duration and the risk of hypertension. Methods 284,250 adults from the UK Biobank (UKB) and 6,104 participants from the English Longitudinal Study of Ageing (ELSA) were analyzed. The exposures of interest were sleep quality and duration. Sleep quality was evaluated based on the number of healthy sleep behaviors (UKB cohort) or questionnaire adapted from the Jenkins Sleep Problems Scale (ELSA cohort). Participants were divided into three groups based on the assessment of sleep quality. Long sleep is characterized by a duration exceeding 8 hours, medium sleep ranges from 7 to 8 hours and short sleep denotes less than 7 hours of sleep. The primary endpoint was incident hypertension. Results In UKB cohort, participants with poor sleep quality showed significantly higher risk of hypertension compared those with healthy sleep quality (hazard ratio [HR] 1.276, confidence interval [CI] 1.21, 1.346). Short sleep duration (≤7h) was associated with an elevated hypertension risk in participants regardless of different sleep quality, and both short(≤7h) and prolonged sleep time (≥9h) were associated with an increased hypertension risk in the poor sleep quality group. Several factors were independently associated with a lower risk of hypertension, including appropriate sleep duration (7-8 hours per day), absence of frequent insomnia, no self-reported snoring(P&amp;lt;0.001). Associations between sleep quality and an increased risk of hypertension remained significant regardless of genetic susceptibility to hypertension (P for interaction= 0.067). Conclusions Poor sleep quality is associated with an elevated risk of hypertension. Adjusting sleep behavior to enhance sleep quality within a recommended range could be a promising strategy for mitigating the risk of hypertension.

2.X.1. Sleep Health Disparities across the life-course: from research to public health policy

Abstract Poor sleep health is a recognized common problem across the life cycle, globally. Factors that contribute to this problem include the demands of a “Western” lifestyle (urgency, productivity), economic stressors, social and environmental determinants of health, and global crises including international conflicts, political tensions, and climate change. There is a growing consensus that optimizing sleep health should be a public health priority because poor sleep patterns are a modifiable risk factor for myriad health outcomes, such as cardiovascular disease, diabetes, cancer, cognitive decline, mental illness, and early mortality. In Canada, a nationwide sleep consortium funded by the Canadian Institutes of Health Research (CIHR) was recently formed with a mandate to generate new knowledge that will inform clinical practice and support public health initiatives to deliver resources where they are most needed. The proposed workshop organized by the Chronic Disease EPH section will start with a general overview of the impact of sleep health disparities across the life-course, from childhood to older age, as well as discuss evidence-based public health approaches to promote sleep hygiene and mitigate the risk of adverse health outcomes, including chronic disease (Saverio Stranges). It will be followed by three presentations to address the root causes of sleep health disparities and their impact on chronic disease (Dayna Johnson); participatory research with families and care providers on infant sleep intervention development (Elizabeth Keys), and strategies to address common sleep disorders among middle-aged and older adults (Tetyana Kendzerska). Key messages • Sleep health disparities are a neglected public health issue. • Optimizing sleep health is both a clinical and public health priority, as sleep patterns represent a modifiable risk factor for a range of adverse health outcomes.

Polysomnographic Findings into Sleep Disorders in Essential Tremor and Essential Tremor Plus: A Comparison with Healthy Controls.

To explore sleep patterns in individuals with Essential Tremor (ET) and Essential Tremor Plus (ET-Plus), compared to healthy controls, and assess differences between ET and ET-Plus, given the lack of established polysomnography (PSG) data on these groups and the potential for sleep disturbances to serve as clinical markers. We conducted a prospective cross-sectional study at NIMHANS, Bengaluru, from November 2021 to August 2023 on 45 patients (26 ET, 19 ET-Plus) and 45 controls. Tremor severity was assessed using TETRAS and FTMTRS, and sleep symptoms with ESS, PSQI, Mayo Sleep Questionnaire, RLS-Q, BQ, GAD-7 and PHQ-9. All cases and controls underwent overnight video PSG. Sleep scoring was manually done by a technically adequate sleep researcher and the first author following AASM (2022) guidelines with data analysed using R studio. ET patients exhibited younger onset age (30.8 ± 16.7 years) compared to ET-Plus patients (46.8 ± 11.1 years). ET-Plus had higher TETRAS and FTMRS scores (P < 0.001) than ET. Both ET and ET-Plus patients exhibited poorer sleep quality, excessive daytime sleepiness, REM sleep behavior disorder (RBD), and Restless Legs Syndrome (RLS) symptoms compared to controls. PSG findings supported these clinical observations, showing elevated Apnea-Hypopnea Index (AHI), reduced Total Sleep Time (TST), prolonged REM latency, decreased sleep efficiency, increased N1 stage duration, and reduced N2/N3 durations and percentages in patients versus controls. The study highlights significant sleep architecture abnormalities in both ET and ET-Plus patients as compared to healthy controls, with no differences between the ET groups.

Daridorexant as a new dual orexin receptor antagonist for insomnia - a literature review

Introduction and purpose of review: Insomnia is a prevalent disorder responsible for multiple negative effects on human health. Its treatment involves both non pharmacological and pharmacological methods, however many common insomnia medications are recommended not to be used long term. Daridorexant is a new dual orexin receptor inhibitor, recently approved by the EMA for use in the European Union. The aim of this study is to present current knowledge concerning daridorexantsafety, efficacy and general characteristics. Methods: Pubmed database literature review has been performed. Relevant studies regarding daridorexant and insomnia have been assessed. Product characteristics available on EMA, FDA and Idorsia Pharmaceuticals websites have also been inspected. Current state of knowledge: Studies suggest that daridorexant is generally safe and significantly improves the night-time and daytime functioning of people suffering from insomnia, by enabling them to fall asleep in shorter periods of time and stay asleep for longer. It increases time spent in both REM and non-REM phases proportionally and does not disturb physiological sleep architecture. It shows no residual effects in the morning and can be used long-term, with no reduced efficacy and with no signs of physical dependence or withdrawal symptoms. It rarely leads to serious adverse effects and is contraindicated only in a few groups of patients. Conclusions: Daridorexant is a recently approved dual orexin receptor inhibitor with a promising long-term use safety and efficacy profile. As it is a new medication, further investigation concerning the side effects observed over time should be advised.

Effects of eHealth literacy on maternal and neonatal outcomes

ABSTRACT eHealth literacy plays a crucial role during pregnancy, as maternal health behavior can influence health outcomes for both mother and child. This study assessed the impact of eHealth literacy on maternal-fetal health outcomes through a cross-sectional analysis of 1,265 pregnant women admitted to a tertiary maternity hospital in Turkey between April and July 2022. Data on sociodemographic information, obstetric variables, birth outcomes, Internet usage, and eHealth Literacy Scale (eHEALS) were collected. Kolmogorov-Smirnov, Mann – Whitney U, Kruskal-Wallis, and Spearman correlation were used for data analysis. The median age of women was 28 years, and the mean gestational age was 38.6 weeks. Median eHealth literacy score was 21 (range:8-40). Pregnant women who had planned pregnancies, received spousal support, attended 9–12 antenatal care visits, received vaccinations, adhered to iron and folic acid supplementation, engaged in regular physical activity, and maintained regular sleep patterns exhibited higher eHealth scores (all p < .001). eHEALS scores were higher in women who experienced normal vaginal deliveries (p < .001), while lower eHEALS scores were noted in those with comorbidities (p = .001). The study suggested that higher eHealth literacy among pregnant women was associated with improved health-promoting behaviors, more favorable health perceptions, increased utilization of health services, and better maternal and fetal outcomes.

Combined association between dietary antioxidant quality score and leisure-time physical activity on sleep pattern in cancer survivors: a cross-sectional study of NHANES database.

This study aimed to explore the combined association between the dietary antioxidant quality score (DAQS) and leisure-time physical activity on sleep patterns in cancer survivors. Data of cancer survivors were extracted from the National Health and Nutrition Examination Surveys (NHANES) database in 2007-2014 in this cross-sectional study. Weighted multivariable logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association of DAQS and leisure-time physical activity on sleep patterns. The combined association was also assessed in subgroups of participants based on age, and use of painkillers and antidepressants. Among the eligible participants, 1,133 had unhealthy sleep patterns. After adjusting for covariates, compared to low DAQS level combined with leisure-time physical activity level <600 MET·min/week, high DAQS level combined with leisure-time physical activity ≥600 MET·min/week was associated with lower odds of unhealthy sleep patterns (OR=0.41, 95%CI: 0.23-0.72). Additionally, the association of high DAQS level combined with high leisure-time physical activity with low odds of unhealthy sleep patterns was also significant in <65 years old (OR=0.30, 95%CI: 0.13-0.70), non-painkiller (OR=0.39, 95%CI: 0.22-0.71), non-antidepressant (OR=0.49, 95%CI: 0.26-0.91) and antidepressant (OR=0.11, 95%CI: 0.02-0.50) subgroups. DAQS and leisure-time physical activity had a combined association on sleep patterns in cancer survivors. However, the causal associations of dietary nutrient intake and physical activity with sleep patterns in cancer survivors needs further clarification.

The interplay among sleep patterns, social habits, and environmental cues: insights from the Spanish population and implications for aligning daily rhythms

IntroductionThe interplay among sleep patterns, social habits and environmental cues is becoming increasingly more important for public health and wellbeing due to its connection to circadian desynchronization. This paper explores said connections in Spain (which has an official and solar time mismatch), introducing the “Three Times Score” ‒which is based on questions widely used in the field‒ as a complementary tool for exploring the interplay of daily rhythms.MethodsThe questionnaire covers sleep-related habits, social time, and environmental time. The study includes 9,947 participants (34.89 ± 12.15 y/o, mean ± SD; 5,561 women) from different Spanish regions. Sleep parameters were obtained for work and free days, as well as a modified version of the sleep-corrected midsleep on free days (MBFbc) and a parameter similar to social jet lag, both derived from bed time rather than sleep time. A number of indexes were computed to compare bed and work-related habits, together with natural light/dark cycle, along with the Three Times Score. Mixed-effect regression analysis was used to test whether the biological, social and environmental factors included in the study significantly predicted the sleep-related parameters: bedtime, wake-up time, time in bed and mid-bedtime.Results and discussionTemporal differences were found between work and free days, with waking-up occurring 2 h earlier on work days (7:10 ± 0:01) than on free days (9:15 ± 0:01). Bed times were 1 h earlier on work days (23:46 ± 0:01) than on free days (00:45 ± 0:01), whereas time in bed was over 1 h shorter on work (7 h 23 min) versus free (8 h 29 min) days. Strong correlations were found between work starting time and waking-up and bedtimes on workdays. Women went to bed earlier and woke up later, spending more time in bed. Differences in sleep habits were observed between work and free days across all age groups. The group of younger adults (18–30) reported going to bed later than older and younger groups, especially on free days. Adolescents and young adults also woke-up later than other age groups, especially on free days. Social jet lag (relative to bed time) and desynchronization indexes also varied with age, with younger adult participants exhibiting higher levels. Seasonal differences were limited, with minor variations between winter and summer. According to the multiple regression analysis, social (day type, work start time, alarm clock usage), biological (age, gender, in most cases related to sex) and environmental (sunset time) factors significantly contribute to predicting sleep/bed related schedules. This study provides insights into sleep habits in the Spanish population, introducing the Three Times Score as a complementary tool for exploring the interactions between sleep/bed-related habits, natural darkness and work-related schedules. Understanding this interplay is crucial for developing tailored interventions to improve sleep and wellbeing.

Association between sleep and tinnitus in US adults: Data from the NHANES (2007-2012).

We evaluated the relationship between sleep factors and tinnitus risk using data from the US National Health and Nutrition Examination Survey (2007-2012), focusing on adults aged 20 to 80 years. Our analysis included 4354 participants, with sleep patterns categorized as healthy, intermediate, or poor. We observed that both short (odds ratio [OR]: 1.43) and long (OR: 1.48) sleep durations increased the risk of tinnitus compared with the healthy range (7-9 hours). Additionally, sleep disturbances were significantly correlated with tinnitus (OR: 1.52), with the strongest association occurring in individuals with poor sleep patterns (OR: 1.71). The results of the weighted logistic regression analysis underscored these findings.

Using motivational interviewing to improve sleep quality among patients with hypertension attending a tertiary hospital in southern Nigeria: a randomized controlled trial

IntroductionRestorative sleep is essential for the maintenance of overall health and for the prevention of chronic diseases, including hypertension. The aim of this study was to determine the effect of motivational interviewing (MI) on sleep quality in patients with hypertension.MethodsThe study was a randomised controlled trial (PACTR202301917477205) of 250 adult patients aged 18 to 65 years (125 in each group) with hypertension presenting to the Family Medicine Clinics of Irrua Specialist Teaching Hospital, Irrua, Nigeria from April to December 2023. Patients were selected through systematic random sampling and randomised into intervention and control group with the intervention group having monthly sessions of motivational interviewing in addition to standard care for hypertension and the control group having standard care only. Data were analysed with Stata with level of significance set at p < 0.05.ResultsThe participants had a mean age of 51.5 ± 10.0 years, were mostly females 156 (62.4%), married 135 (54.0%), and Christians 134 (53.6%). There was no significant difference in the sleep pattern of both the intervention and control groups (χ2 = 1.111 and p = 0.292) at baseline. Post-intervention with MI, there was a significant improvement in sleep quality (p = 0.002) and a corresponding improvement in blood pressure control (p < 0.001) of patients in the intervention group compared to controls.ConclusionThe use of motivational interviewing led to a significant improvement in sleep quality and a corresponding improvement in blood pressure control. Motivational interviewing should be employed by physicians and other health workers during sleep prescription counselling.

Interactions Between Eleven Sleep-Related Characteristics and Diabetic Nephropathy: A Bidirectional Mendelian Randomization Study in European Population.

Observational studies often report disturbed sleep patterns in individuals with diabetic nephropathy (DN). The possible causal relationship behind these connections remains unknown. This research assessed the possible cause-and-effect relationship between eleven sleep-related characteristics and the risk of developing DN using a two-sample Mendelian randomization (MR) study. This study employed a two-sample bidirectional MR analytical approach. Genetic data for eleven sleep-related characteristics were acquired from the genome-wide association studies (GWAS) database of individuals of European ancestry which involve scanning complete sets of DNA, or genomes. GWAS summary data for DN included 4,111 DN cases and 308,539 controls. Instrumental variables were single nucleotide polymorphisms strongly linked to sleep-related characteristics. The main analysis used the random-effects inverse variance weighted (IVW) approach, with validation through sensitivity testing. MR analysis revealed that a higher genetic predisposition for sleep efficiency reduced the chance of developing DN (odds ratio [OR]: 0.384; 95% confidence interval [CI] 0.205-0.717; p=0.003). Genetic susceptibility to DN was associated with a higher likelihood of experiencing more sleep episodes (OR: 1.015; 95% CI 1.003-1.028; p=0.016). Sensitivity analysis confirmed the robustness of these correlations. No significant connections were found between other genetically predicted sleep characteristics and the likelihood of developing DN. Our research indicates that a genetic predisposition for better sleep efficiency is linked to a lower risk of developing DN. There is also evidence suggesting that genetic predisposition to DN may directly impact sleep episodes. Further research is needed to explore the molecular mechanisms underlying these findings.
