Abstract Objective Poor sleep is a modifiable risk factor for multiple disorders. Frontline treatments (e.g. cognitive-behavioral therapy for insomnia) have limitations, prompting a search for alternative approaches. Here, we compare manualized Mindfulness-Based Therapy for Insomnia (MBTI) with a Sleep Hygiene, Education, and Exercise Program (SHEEP) in improving subjective and objective sleep outcomes in older adults. Methods We conducted a single-site, parallel-arm trial, with blinded assessments collected at baseline, post-intervention and 6-months follow-up. We randomized 127 participants aged 50–80, with a Pittsburgh Sleep Quality Index (PSQI) score ⩾5, to either MBTI (n = 65) or SHEEP (n = 62), both 2 hr weekly group sessions lasting 8 weeks. Primary outcomes included PSQI and Insomnia Severity Index, and actigraphy- and polysomnography-measured sleep onset latency (SOL) and wake after sleep onset (WASO). Results Intention-to-treat analysis showed reductions in insomnia severity in both groups [MBTI: Cohen's effect size d = −1.27, 95% confidence interval (CI) −1.61 to −0.89; SHEEP: d = −0.69, 95% CI −0.96 to −0.43], with significantly greater improvement in MBTI. Sleep quality improved equivalently in both groups (MBTI: d = −1.19; SHEEP: d = −1.02). No significant interaction effects were observed in objective sleep measures. However, only MBTI had reduced WASOactigraphy (MBTI: d = −0.30; SHEEP: d = 0.02), SOLactigraphy (MBTI: d = −0.25; SHEEP: d = −0.09), and WASOPSG (MBTI: d = −0.26; SHEEP (d = −0.18). There was no change in SOLPSG. No participants withdrew because of adverse effects. Conclusions MBTI is effective at improving subjective and objective sleep quality in older adults, and could be a valid alternative for persons who have failed or do not have access to standard frontline therapies.

BACKGROUND The current Covid-19 pandemic has brought about a marked interest in sleep health, as well as an increased demand for telehealth services, such as online Cognitive Behavioral Therapy for insomnia (CBT-I). Older adults in particular report a high rate of sleep problems. Recent studies have suggested that dysfunctional sleep beliefs could contribute to the high rates of self-reported insomnia in this age group. In addition, older adults have an increased rate of uncoupled sleep, e.g. displaying an insomnia complaint in the absence of objectively measured poor sleep. It is essential to determine the prevalence of coupled and uncoupled sleep in older adults and to examine the efficacy of online CBT-I to improve sleep outcomes. OBJECTIVE This study aims to assess objective and subjective sleep quality and dysfunctional sleep beliefs in a sample of community-dwelling older adults aged 60-80 years with and without uncoupled sleep in Western Australia following digitally delivered CBT-I. METHODS Objective sleep was measured using wrist actigraphy, and subjective sleep quality via sleep diaries and the Pittsburgh Sleep Quality Index (PSQI). Dysfunctional sleep beliefs were assessed by the Dysfunctional Beliefs and Attitudes about Sleep scale (DBAS-16) prior to and following a four-week online CBT-I programme. Linear mixed model and generalised linear mixed model analyses were conducted to examine objective and subjective sleep onset latency, total sleep time, wake after sleep onset and number of awakenings as well as PSQI and DBAS16 scores, respectively. RESULTS 62 participants (55 females; 88.7%) completed the study. CBT-I effectively reduced dysfunctional sleep beliefs and PSQI scores across all sleep classifications, even in good sleepers without a sleep complaint. Objective and self-reported changes in sleep parameters were mainly demonstrated in complaining poor sleepers. Complaining good sleepers reported a decrease in the number of subjective sleep awakenings only. CONCLUSIONS Online CBT-I was effective in improving the sleep outcomes of individuals who had both subjective and objective poor sleep. However, as the online CBT-I reduced dysfunctional sleep beliefs in all sleep groups, further examination of dysfunctional sleep beliefs and whether they mediate the outcomes of digital CBT-I in older adults will need to be conducted.

Introduction: Poor sleep and history of weight cycling (HWC) are associated with worse cardiovascular health, yet limited research has evaluated the association between HWC and poor sleep patterns. Hypothesis: We hypothesized that HWC would be associated with poor sleep in US women. Methods: The AHA Go Red for Women Strategically Focused Research Network cohort at Columbia University (n=506, mean age 37 ± 15.7y, 61% racial/ethnic minority) was used to evaluate cross-sectional associations of HWC and sleep characteristics at baseline, and prospective associations of HWC from baseline with sleep measures at 1-yr. HWC, defined as losing and gaining ≥ 10 lbs at least once (excluding pregnancy), and number of WC episodes were self-reported. Sleep duration, measures of sleep quality, insomnia severity, and obstructive sleep apnea (OSA) risk were assessed using the validated Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Berlin questionnaire. Linear and logistic regression models, adjusted for age, race/ethnicity, education, health insurance status, pregnancy history, and menopausal status, were used to evaluate the relation of HWC with sleep. Results: Most women reported ≥1episode of weight cycling (72%). In linear models of cross-sectional and prospective data, each additional weight cycling episode was related to shorter sleep duration, poorer sleep quality, longer sleep onset latency, greater insomnia severity, more sleep disturbances and daytime dysfunction, lower sleep efficiency, and higher sleep medication use frequency. In logistic models, HWC (≥1 vs. 0 episodes) was associated with greater odds for short sleep, poor sleep quality, long sleep onset latency ≥26 min, high OSA risk, and sleep efficiency<85% ( Table ). Conclusion: HWC predicted poor sleep among women, suggesting that weight maintenance may represent an important strategy to promote sleep health. Long-term studies are needed to disentangle the complex relations between weight fluctuations and sleep across the life course.

Background: Face-to-face cognitive behavioral therapy (CBT) is one of the most widely used non-pharmacological treatment approaches for insomnia. The aim of this study is to assess the efficacy of face-to-face delivered CBT on health outcomes and to evaluate the effect of CBT components as subgroup variables to explain the efficacy of face-to-face delivered CBT on health outcomes in adults over 18 years old with insomnia.Methods: Relevant randomized controlled trial studies published in the past 22 years were searched through the electronic databases. The Physiotherapy Evidence Database (PEDro) scale was used to assess the quality of the 31 included studies. The mean difference and standard deviation of outcome variables and subgroup variables were analyzed using random effect model, and the heterogeneity among the articles was assessed with the Q-test and I2. Egger regression analysis was used to assess publication bias.Results: The meta-analysis showed a significant reduction in Insomnia Severity Index [standardized mean difference (SMD) = −2.56, 95% CI −3.81 to −1.30, p &lt; 0.001], Pittsburgh Sleep Quality Index (SMD = −0.96, 95% CI −1.25 to −0.68, p &lt; 0.001), sleep onset latency (SMD = −1.31, 95% CI −2.00 to −0.63, p &lt; 0.001), wakening after sleep onset (SMD = −1.44, 95% CI −2.14 to −0.74, p &lt; 0.001), number of awakenings (SMD = −1.18, 95% CI −2.10 to −0.26, p &lt; 0.05), depression (SMD = −1.14, 95% CI −1.85 to −0.42, p &lt; 0.01), and fatigue (SMD = −2.23, 95% CI −3.87 to −0.58, p &lt; 0.01), and a significant increase in total sleep time (SMD = 0.63, 95% CI 0.28 to 0.98, p &lt; 0.001), sleep efficiency (SMD = 1.61, 95% CI 0.92 to 2.29, p &lt; 0.001), and physical health (SMD = 0.42, 95% CI 0.08 to 0.76, p &lt; 0.05), in the CBT intervention group compared with the control group. There was no significant change in anxiety (SMD = −0.62, 95% CI −1.55 to 0.32, p &gt; 0.05) and mental health (SMD = 1.09, 95% CI −0.59 to 2.77, p &gt; 0.05) in CBT intervention group compared with control group. Group-delivered studies with larger number of intervention sessions and longer duration of single session provided a larger improvement in sleep quality.Conclusion: Face-to-face delivered CBT is effective in increasing total sleep time, sleep efficiency, and physical health, and reducing Insomnia Severity Index scores, Pittsburgh Sleep Quality Index scores, sleep onset latency, wakening after sleep onset, number of awakenings, depression, anxiety, and fatigue in patients with insomnia. Face-to-face delivered CBT is more effective when delivered through a larger number of sessions with longer duration of each session, and when delivered in groups. Face-to-face CBT is recommended to provide treatment to patients with insomnia in clinical settings.Systematic Review Registration:www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020200091, identifier: CRD4202020009.

Background: Approximately 50%of older adults with cognitive impairment suffer from insomnia. When untreated, pre-existing cognitive problems may be exacerbated and potentially contribute to further cognitive decline. One promising approach to maintain cognitive health is to improve sleep quantity and quality. Objective: To determine feasibility, acceptability, and preliminary efficacy of Sleep Health Using the Internet for Older Adult Sufferers of Insomnia and Sleeplessness (SHUTi OASIS), an Internet-delivered cognitive behavioral therapy for insomnia (CBT-I) program in older adults with mild cognitive impairment (MCI). Methods: Older adults with MCI and insomnia were recruited from hospital-based memory and sleep disorders clinics and enrolled in a single-arm pilot study. Participants completed the six cores of SHUTi OASIS, over nine weeks with two-week baseline and post-assessments using self-reported sleep diaries. Feasibility and acceptability were informed by usage statistics and qualitative interviews; preliminary efficacy was informed by patient-generated sleep data. Results: Twelve participants enrolled and, on average, were 75.8 years of age. Ten participants completed the study and logged in most days. Most participants reported a positive overall experience, and interviews revealed successful and independent program management and completion. There were significant changes on all baseline to post-assessment sleep measures, including clinically meaningful improvements on the Insomnia Severity Index (13.5 to 8.3, p <  0.01), sleep efficiency, wake after sleep onset, and sleep onset latency (ps <  0.02). There was no statistically significant change in cognitive measures (p >  0.05). Conclusion: This study supports that older adults with cognitive impairment can independently complete CBT-I via the Internet and achieve clinical sleep improvements.

Abstract Introduction The prevalence of insomnia complaints in older adults is 30–48%, compared to 10–15% in the general population. Cognitive Behavioral Therapy for Insomnia (CBT-I) is a first-line, non-pharmacological sleep treatment for Insomnia. However, the relative impact of Behavioral (BT) and Cognitive (CT) components compared to that of CBT-I in older adults is unknown. Methods 128 older adults with insomnia were randomized to receive CBT-I, BT, or CT. Sleep diaries and the Insomnia Severity Index (ISI) were collected pre- and post-treatment and at a 6-month follow-up. We conducted split-plot linear mixed models with age and sex as covariates to assess within and between subject changes to test effects of group, time, and their interaction on ISI, sleep onset latency (SOL), wake after sleep onset (WASO), total sleep time (TST), time in bed (TIB), sleep efficiency (SE), and percent of treatment responders (ISI decrease&gt;7) and remitters (ISI&lt;8). Effect size (d) was calculated by dividing the difference between means by the root-mean-squared error of the mixed effects model. Results All treatments lead to a significant improvement across outcome measures at post-treatment (p’s&lt;0.001) and 6-months (p’s&lt;0.01), with the exception of TIB, response, and remission. For TIB, there was a significant Group x Time interaction (p&lt;0.001): while all treatments significantly reduced TIB post-treatment relative to baseline, CBT-I (p&lt;0.001,d=-2.26) and BT (p&lt;0.001,d=-1.59) performed significantly better than CT (p=0.003, d=-0.68). In contrast, at 6-months CBT-I (p&lt;0.001,d=-1.16) performed significantly better at reducing TIB than CT (p=0.195,d=-0.24) or BT (p=0.023,d=-0.61) relative to baseline. There was also a non-significant trend for a Group x Time interaction for remission status (p=0.062). Whereas, the percentage of remitters within all groups post-treatment did not differ from chance (p&gt;0.234), at 6 months, the percentage of remitters was significantly higher than chance in CBT-I (73.63%,p=0.026) and BT (78.08%,p=0.012), but not CT (47.85%,p=0.826). There were no other significant time or interaction effects (all p&gt;0.05). Conclusion CBT-I and its components are effective in improving subjective insomnia symptoms in older adults. Evidence suggests CBT-I may be superior to either CT or BT alone in improving TIB in older adults. Support (if any) NIMHR01MH101468; MIRECC at VAPAHCS

Abstract Introduction Cognitive behavioral therapy for insomnia (CBT-I) is efficacious, but there is mixed evidence as to whether improvement is blunted in adults with insomnia and short sleep duration. Exercise training can reduce physiologic hyperarousal and may increase homeostatic sleep drive, which could potentiate CBT-I treatment effects. This pilot study explored changes in self-reported outcomes from a CBT-I intervention augmented by exercise training in a sample of adults with insomnia and objective short sleep duration. Methods Eight adults (50% female, 62.5% white) with insomnia disorder and short sleep duration (mean actigraphic TST &lt;6.5 hr) completed a 12-week single-arm trial. Participants self-administered the online “Sleep Healthy Using the Internet” (SHUT-I) CBT-I program with additional staff guidance while completing a supervised exercise program (EX; 150 min/wk of moderate-intensity aerobic exercise and 2 days/wk of strength training). Participants completed assessments of self-reported sleep and daytime function pre- and post-intervention, including the Insomnia Severity Index (ISI), Flinders Fatigue Scale (FFS), Ford Insomnia Response to Stress Test (FIRST), Perceived Stress Scale (PSS), and Epworth Sleepiness Scale (ESS). Differences between timepoints were analyzed using paired t-tests and Cohen’s d effect size calculations. Results Insomnia severity significantly decreased after the intervention (ISI: p&lt;0.001, d=2.99), with 75% reporting post-intervention ISI ≤ 7. Likewise, fatigue significantly decreased after the intervention (FFS: p=0.032, d=0.95). Symptoms of stress-related sleep reactivity and stress were also reduced (FIRST: p=0.012, d=1.19; PSS: p=0.014, d=1.14). Though nonsignificant, large reductions in sleepiness were additionally observed (ESS: p=0.058, d=0.80). Conclusion In this pilot trial among patients with insomnia and short sleep duration, online CBT-I plus a supervised exercise program resulted in a significant reduction in insomnia severity. The intervention also produced large and meaningful reductions in fatigue and stress, which are common daytime impairments in patients with insomnia. Future research should attempt to disentangle the independent contributions of CBT-I and exercise on outcomes in this population. Support (if any) NIH: K23HL118318

Background: Time restricted feeding (TRF) involves deliberately restricting the times during which energy is ingested. Preliminary findings suggest that 8–10-h TRF improves sleep. However, the effects of shorter TRF windows (4–6 h) on sleep, remain unknown. Aims: This study compared the effects of 4-h versus 6-h TRF on sleep quality, duration, insomnia severity and the risk of obstructive sleep apnea. Methods: Adults with obesity ( n = 49) were randomized into one of three groups: 4-h TRF (eating only between 3 and 7 p.m.), 6-h TRF (eating only between 1 and 7 p.m.), or a control group (no meal timing restrictions) for 8 weeks. Results: After 8 weeks, body weight decreased ( p < 0.001) similarly by 4-h TRF (–3.9 ± 0.4 kg) and 6-h TRF (–3.4 ± 0.4 kg), versus controls. Sleep quality, measured by the Pittsburgh Sleep Quality Index (PSQI), did not change by 4-h TRF (baseline: 5.9 ± 0.7; week 8: 4.8 ± 0.6) or 6-h TRF (baseline: 6.4 ± 0.8; week 8: 5.3 ± 0.9), versus controls. Wake time, bedtime, sleep duration and sleep onset latency also remained unchanged. Insomnia severity did not change by 4-h TRF (baseline: 4.4 ± 1.0; week 8: 4.7 ± 0.9) or 6-h TRF (baseline: 8.3 ± 1.2; week 8: 5.5 ± 1.1), versus controls. Percent of participants reporting obstructive sleep apnea symptoms did not change by 4-h TRF (baseline: 44%; week 8: 25%) or 6-h TRF (baseline: 47%; week 8: 20%), versus controls. Conclusion: These findings suggest that 4- and 6-h TRF have no effect on sleep quality, duration, insomnia severity, or the risk of obstructive sleep apnea.

Abstract Introduction Insomnia and related anxiety affect 30 - 50% of the US adult population. These conditions often coexist, and contribute to increased mortality from depression, heart disease, and stroke. The current COVID-19 pandemic has heightened anxiety and sleeplessness, and 53% of US adults report the pandemic has affected their mental health. There is a need for research into therapies for anxiety and insomnia that can be delivered remotely for increased accessibility to reach more individuals in need. Methods To contribute to this need, we examined the effects of remotely delivered Yoga Nidra (translated to mean “yogic sleep”), a guided meditation practice, on anxiety and sleep. The practice was delivered in real-time before bed, or asynchronously via an online REDCap-based platform, once per week for 16-weeks from April to July (during the early months of the COVID-19 pandemic). Results Seventy-four individuals joined the study, of whom 71% reported subthreshold insomnia (Insomnia Severity Index score of 14 ± 4), and 74% reported anxiety (Generalized Anxiety Disorder Index score of 10 ± 5). Seventy-one (96%) participants accessed the asynchronous recordings. Remote delivery of this practice proved very feasible, with no adverse events reported, and although we provided no monetary compensation, 50% of our sample still completed a post-intervention survey. Further, 52% of n=25 respondents who completed both pre- and post-intervention sleep surveys reported decreased sleep onset latency (SOL) the following day, with a mean decrease of 10 minutes (95% CI = −19.0, −0.5) for all respondents, and strongest change (−34 min; p=.017) measured for those who reported SOL between 30-120 min at baseline. Overall state anxiety was decreased by 41% for n=32 respondents who completed pre-post State Trait Anxiety Index (STAI) surveys surrounding a single practice (average score of 47 ± 11 before practice vs. 27 ± 8 after practice, p&lt;.0001). Conclusion Remotely delivered Yoga Nidra is feasible to deliver, and demonstrates potential benefits for anxiety and insomnia, warranting additional research.

Poor Sleep Quality

Abstract Introduction Recent studies show that sleep favors oligodendrocyte proliferation and myelination, and sleep loss is associated with alterations in white matter structure and decreased myelination. Psychotic disorders are characterized by disrupted white matter integrity, and abnormal axon and myelin structure. Despite common sleep disturbances in these disorders, little is known about the relationship between sleep quality and white matter findings. A novel in vivo neuroimaging technique that combines diffusion tensor spectroscopy (DTS) and magnetization transfer ratio (MTR) allows separately examining the axon structure and glial function, and myelin content, respectively. Using this method, we examined the association of sleep quality with white matter biology in a sample of patients with psychotic disorders and matched healthy controls. Methods Participants included patients diagnosed with bipolar disorder with psychotic features (euthymic or depressed, n=12) and schizophrenia spectrum disorders (n=9), and age and sex matched healthy controls (n=20). DTS and MTR data was collected from the right prefrontal white matter at 4T. DTS measures included apparent diffusion coefficients of water, NAA, creatine and choline. Sleep quality was measured using Pittsburgh Sleep Quality Index (PSQI). Results PSQI total score was significantly higher in patients. and patient sample included a higher percentage of poor sleepers (PSQI total score&gt;5). In patients, total PSQI score and sleep onset latency were significantly and negatively associated with MTR (F=6.9, p=0.02 and F=9.7, p=0.007, respectively). There was no difference in any DTS measures between groups. Conclusion Our preliminary results show that poor sleep quality is associated with decreased myelin content in the frontal lobe, in patients with psychotic disorders. This finding suggests that sleep loss may be a mediator of white matter alterations in psychosis.

Abstract Introduction Insomnia among informal caregivers (providing care to family/friends) is common and associated with worse mental and physical health outcomes. Traditional cognitive behavioral therapy for insomnia may be challenging for caregivers whose beliefs about sleep may relate to beliefs and behaviors that are intertwined with their unique situation of caregiving. We examined whether an insomnia treatment using an acceptance and commitment (ACT) approach (i.e. committing to values-based actions toward goals vs. experiential avoidance of distressing emotions/thoughts) plus sleep restriction, stimulus control and sleep hygiene improves sleep, mental health, and daytime symptoms among caregivers. Methods We analyzed data from women veterans with insomnia who were informal caregivers (mean age=44 years [range 25–57]; N=6) and were participating in a clinical trial of an ACT-focused treatment (termed ABC-I). We measured: Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Patient Health Questionnaire (PHQ-9), General Anxiety Disorder (GAD-7), 11 items assessing symptoms of daytime impairment due to poor sleep derived from the International Classification of Sleep Disorders-Third Edition, and the Acceptance and Action Questionnaire (AAQ). Student t-tests were used to compare outcomes between pre- and post-ABC-I. Results Caregivers showed significant improvements between pre- and post-ABC-I (all p-values&lt;0.05) in the following outcomes: ISI (14.3±5.4 vs. 3.8±3.2), PHQ-9 (9.8±7.2 vs. 2.8±3.8), GAD-9 (9.0±6.6 vs. 2.0±1.8), and number of symptoms of sleep-related daytime impairment (6.8±4.0 vs. 3.8±3.5). Caregivers also showed improvement trends in PSQI (10.0±4.1 vs. 5.2±1.2, p=0.06) and AAQ score (24.0±12.7 vs. 16.2±8.0, p=0.05). Conclusion We found that caregivers with insomnia may benefit from ACT-based treatment in improving perceived sleep quality and insomnia, depression, anxiety, sleep-related daytime impairment and reduced experiential avoidance.
