Study Objectives Neurocognitive impairments in comorbid insomnia and sleep apnea (COMISA) are not well documented. We explored neurocognitive functioning and treatment effects in individuals with COMISA as an ancillary study to a randomized clinical trial (RCT). Methods Participants with COMISA (n=45; 51.1% female; mean age=52.07±13.29 years), from a 3-arm RCT combining Cognitive Behavioral Therapy for insomnia (CBT-I) and Positive Airway Pressure (PAP) concurrently (CBT-I+PAP) or sequentially, completed neurocognitive testing at baseline, and post-treatment. Using Bayesian linear mixed models, we estimated effects of CBT-I, PAP, or CBT-I+PAP, compared to baseline, and CBT-I+PAP compared to PAP on 12 metrics across 5 cognitive domains. Results This COMISA sample had worse neurocognitive performance at baseline than reported for insomnia, sleep apnea, and controls in the literature, though short-term memory and psychomotor speed performance appears intact. When comparing PAP to baseline, performance on all measures was better after treatment. Performance after CBT-I was worse compared to baseline, and only performance in attention/vigilance, executive functioning via Stroop interference and verbal memory was better with moderate-high effect sizes and moderate probability of superiority (61-83). Comparisons of CBT-I+PAP to baseline generated results similar to PAP and comparing CBT-I+PAP to PAP revealed superior performance in only attention/vigilance via PVT lapses and verbal memory for PAP. Conclusions Treatment combinations involving CBT-I were associated with poorer neurocognitive performance. These potentially temporary effects may stem from sleep restriction, a component of CBT-I often accompanied by initially reduced total sleep time. Future studies should examine long-term effects of individual and combined COMISA treatment pathways to inform treatment recommendations.

STUDY OBJECTIVES: This study examines the impact of cognitive behavioral therapy for insomnia (CBT-I) and positive airway pressure (PAP) therapy for comorbid insomnia and sleep apnea on nocturnal sleep and daytime functioning. METHODS: A partial factorial design was used to examine treatment pathways with CBT-I and PAP and the relative benefits of each treatment. One hundred eighteen individuals with comorbid insomnia and sleep apnea were randomized to receive CBT-I followed by PAP, self-monitoring followed by CBT-I concurrent with PAP, or self-monitoring followed by PAP only. Participants were assessed at baseline, PAP titration, and 30 and 90 days after PAP initiation. Outcome measures included sleep diary- and actigraphy-measured sleep, Flinders Fatigue Scale, Epworth Sleepiness Scale, Functional Outcome of Sleep Questionnaire, and cognitive emotional measures. RESULTS: A main effect of time was found on diary-measured sleep parameters (decreased sleep onset latency and wake after sleep onset; increased total sleep time and sleep efficiency) and actigraphy-measured sleep parameters (decreased wake after sleep onset; increased sleep efficiency) and daytime functioning (reduced Epworth Sleepiness Scale, Flinders Fatigue Scale; increased Functional Outcome of Sleep Questionnaire) across all arms (all P < .05). Significant interactions and planned contrast comparisons revealed that CBT-I was superior to PAP and self-monitoring on reducing diary-measured sleep onset latency and wake after sleep onset and increasing sleep efficiency, as well as improving Functional Outcome of Sleep Questionnaire and Flinders Fatigue Scale compared to self-monitoring. CONCLUSIONS: Improvements in sleep and daytime functioning were found with PAP alone or concomitant with CBT-I. However, more rapid effects were observed on self-reported sleep and daytime performance when receiving CBT-I regardless of when it was initiated. Therefore, concomitant treatment appears to be a favorable approach to accelerate treatment outcomes.

ObjectivePoor 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.MethodsWe 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).ResultsIntention-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.ConclusionsMBTI 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.

Comorbid insomnia and sleep apnea (COMISA) are the most common co-occurring sleep disorders and present many challenges to clinicians. This review provides an overview of the clinical challenges in the management of patients with COMISA, with a focus on recent evidence regarding the evaluation and treatment of COMISA. Innovations in the assessment of COMISA have used profile analyses or dimensional approaches to examine symptom clusters or symptom severity that could be particularly useful in the assessment of COMISA. Recent randomized controlled trials have provided important evidence about the safety and effectiveness of a concomitant treatment approach to COMISA using cognitive-behavioral therapy for insomnia (CBT-I) with positive airway pressure (PAP). Furthermore, patient-centered considerations that integrate patient characteristics, treatment preferences, and accessibility to treatment in the context of COMISA are discussed as opportunities to improve patient care. Based on these recent advances and clinical perspectives, a model for using multidisciplinary, patient-centered care is recommended to optimize the clinical management of patients with COMISA.

Objective: To examine the relationship between headaches, naps, and nocturnal sleep in women with chronic migraine (CM) using micro-longitudinal data from diaries and actigraphy. Methods: 20 women with CM and 20 age and sex-matched healthy controls (HC) completed self-report questionnaires, electronic diaries, and wrist actigraphy over a 4-week period. Between-group comparisons were conducted with naps (frequency and duration) as the primary variable of interest. Within-group analyses were conducted on the CM group using hierarchical linear mixed models to examine the temporal relationships between headache severity, sleep behaviors, and sleep parameters. The primary variables of interest were naps (number and duration) and nocturnal sleep efficiency (diary and actigraphy). Results: The CM group reported significantly more days with naps (25.85%) compared to the HC group (9.03%) during the study period (p = .0025). Within-group analyses in CM revealed that greater headache severity was associated with longer nap duration (p = .0037) and longer nap duration was associated with lower sleep efficiency measured using diaries (p = .0014) and actigraphy (p

Sleep difficulties, particularly symptoms of insomnia and circadian disruption, are among the primary complaints of gynecologic cancer survivors before, during, and after treatment. Moreover, difficulty sleeping has been linked to poorer health-related quality of life and elevated symptom burden in this population. Although leading behavioral sleep interventions have demonstrated efficacy among cancer survivors, up to 50% of survivors are non-adherent to these treatments, likely because these interventions require labor-intensive behavior and lifestyle changes. Therefore, there is a need for more effective and acceptable approaches to diminish sleep disturbance among cancer survivors. This manuscript describes the methodology of a two-part study guided by the Multiphase Optimization Strategy (MOST) framework to identify a streamlined behavioral sleep intervention for gynecologic cancer survivors. Three candidate intervention components previously shown to decrease sleep disturbance will be evaluated, including sleep restriction, stimulus control, and systematic bright light exposure. Participants will be adult women with a history of non-metastatic gynecologic cancer who have completed primary treatment and who report current poor sleep quality. Fifteen participants will be recruited for Part 1 of the study, which will utilize qualitative methods to identify barriers to and facilitators of intervention adherence. Results will inform changes to the delivery of the candidate intervention components to promote adherence in Part 2, where 80 participants will be recruited and randomized to one of eight conditions reflecting every possible combination of the three candidate intervention components in a full factorial design. Participants will complete assessments at baseline, post-intervention, and 3-months post-intervention. Part 2 results will identify the combination of candidate intervention components that yields the most efficacious yet efficient 6-week intervention for diminishing sleep disturbance. This is the first known study to apply the MOST framework to optimize a behavioral sleep intervention and will yield a resource-efficient treatment to diminish sleep disturbance, improve health-related quality of life, and decrease symptom burden among gynecologic cancer survivors.

Insomnia is a common major health concern, which causes significant distress and disruption in a person's life. The objective of this paper was to evaluate a 6-week version of Mindfulness-Based Therapy for Insomnia (MBTI) in a sample of people attending a sleep disorders clinic with insomnia, including those with comorbidities. Thirty participants who met the DSM-IV-TR diagnosis of insomnia participated in a 6-week group intervention. Outcome measures were a daily sleep diary and actigraphy during pre-treatment and follow-up, along with subjective sleep outcomes collected at baseline, end-of-treatment, and 3-month follow-up. Trend analyses showed that MBTI was associated with a large decrease in insomnia severity (p < .001), with indications of maintenance of treatment effect. There were significant improvements in objective sleep parameters, including sleep onset latency (p = .005), sleep efficiency (p = .033), and wake after sleep onset (p = .018). Significant improvements in subjective sleep parameters were also observed for sleep efficiency (p = .005) and wake after sleep onset (p < .001). Overall, this study indicated that MBTI can be successfully delivered in a sleep disorders clinic environment, with evidence of treatment effect for both objective and subjective measures of sleep.

Objective/background Knowledge of idiopathic hypersomnia symptomatology derives from clinical case series. Web-based registries provide complementary information by allowing larger sample sizes, with greater geographic and social diversity. Patients/methods Data were obtained from the Hypersomnia Foundation's online registry. Common clinical features of idiopathic hypersomnia and other central disorders of hypersomnolence were queried, for the last thirty days and when symptoms were most severe. Symptoms were compared between idiopathic hypersomnia participants with and without long sleep durations and between participants with idiopathic hypersomnia and those with either form of narcolepsy. Frequency of medication use and residual symptoms on medication were evaluated. Results Five-hundred sixty-three registry respondents were included, with idiopathic hypersomnia (n = 468), narcolepsy type 2 (n = 44), and narcolepsy type 1 (n = 51). “Brain fog,” poor memory, and sleep drunkenness were all present in most idiopathic hypersomnia respondents, with brain fog and sleep drunkenness more commonly endorsed by those with long sleep durations. Eighty-two percent of participants with idiopathic hypersomnia were currently treated with medication, most commonly traditional psychostimulants such as amphetamine salts. Among treated patients, symptoms improved while on medication, but substantial residual hypersomnia symptoms remained. Participants with narcolepsy type 1 were more likely than those with idiopathic hypersomnia to endorse intentional and unintentional daytime naps and automatic behaviors. Conclusions Symptoms of idiopathic hypersomnia extend well beyond excessive daytime sleepiness, and these symptoms frequently persist despite treatment. These findings highlight the importance of online registries in identifying gaps in the use and effectiveness of current treatments.

Over the past decade, the emergence of mindfulness meditation as a self-regulation practice has led to a substantial body of evidence on the use of mindfulness-based interventions (MBIs) for insomnia and sleep disturbances. This literature has matured with several randomized controlled trials now published and a number of systematic reviews and meta-analyses are recently available. Collectively, there is a general support for the effectiveness of MBIs on self-reported patient outcomes although the quality of studies varies and the findings on objective measures are equivocal. Building upon this literature, further research is needed to examine biological correlates associated with mindfulness practice, whether the timing of meditation practice is related to sleep outcomes, who is likely to succeed with MBI, and the use of technology in the delivery of MBIs.

Objective/Background: Insomnia commonly co-occurs with chronic migraines (CM). Non-pharmacological treatments for insomnia in CM patients remain understudied. This is a proof-of-concept study, which aims to evaluate the feasibility, acceptability, and preliminary efficacy of a digital cognitive behavioral therapy for insomnia (dCBT-I) for individuals with CM and insomnia (CM-I) in the United States. Methods: We recruited 42 females with CM-I symptoms from a U.S.-based observational cohort and from the general population via advertisements. Within a multiple baseline design, participants were randomized to receive dCBT-I after 2, 4, or 6 weeks of completing baseline sleep diaries. DCBT-I was scrutinized against benchmarks for completion rates (≥90% to complete dCBT-I), acceptability (≥80% to find dCBT-I acceptable), and posttreatment changes in insomnia symptoms (≥50% indicating a clinically relevant improvement in their insomnia symptoms). As a secondary measure, we also reported percentage of individuals reverting to episodic migraines. Results: Out of 42 randomized, 35 (83.3%) completed dCBT-I within the 12 weeks provided. Of these completers, 33 (94.3%) reported being satisfied (n = 16) or very satisfied (n = 17) with treatment. Additionally, 65.7% of completers responded to treatment as per universally accepted criteria for insomnia. Lastly, 34% of completers reverted from CM to episodic migraine. Conclusion: This study provides evidence for the feasibility and acceptability of dCBT-I in patients with CM-I complaints. Effects of improving insomnia and migraines were suggested. These results indicate that a randomized controlled trial is needed to determine the efficacy of dCBT-I in CM patients.

Background Sleep problems and depression are highly prevalent in pregnancy. Nocturnal rumination has been linked to insomnia and depression in non-pregnant samples, but remains poorly characterized in pregnancy. This study explored relationships of depression and suicidal ideation with insomnia, short sleep, and nocturnal rumination in mid-to-late pregnancy. Methods In this study, 267 pregnant women were recruited from obstetric clinics and completed online surveys on sleep, depression, and nocturnal rumination. Results Over half (58.4%) of the sample reported clinical insomnia on the Insomnia Severity Index, 16.1% screened positive for major depression on the Edinburgh Postnatal Depression Scale (EPDS), and 10.1% endorsed suicidal ideation. Nocturnal rumination was more robustly associated with sleep onset difficulties than with sleep maintenance issues. Depressed women were at greater odds of sleep onset insomnia (OR = 2.80), sleep maintenance insomnia (OR = 6.50), high nocturnal rumination (OR = 6.50), and negative perinatal-focused rumination (OR = 2.70). Suicidal ideation was associated with depression (OR = 3.64) and negative perinatal-focused rumination (OR = 3.50). A four-group comparison based on insomnia status and high/low rumination revealed that pregnant women with insomnia and high rumination endorsed higher rates of depression (35.6%) and suicidal ideation (17.3%) than good-sleeping women with low rumination (1.2% depressed, 4.9% suicidal). Women with insomnia alone (depression: 3.9%, suicidal: 5.9%) or high rumination alone (depression: 10.7%, suicidal: 7.1%) did not differ from good-sleeping women with low rumination. Conclusions High rumination and insomnia are highly common in mid-to-late pregnancy and both are associated with depression and suicidal ideation. Depression and suicidal ideation are most prevalent in pregnant women with both insomnia and high rumination. ClinicalTrials.gov identifier NCT03596879 .

Non-communicable diseases, including diabetes, are partly responsible for the deceleration of improvements of life expectancy in many countries. Diabetes is also associated with sleep disturbances. Our aim was to determine whether sleep disturbances, particularly in people with diabetes, were associated with increased mortality risk. Data from the UK Biobank were analysed (n = 487,728, mean follow-up time = 8.9 years). The primary exposure was sleep disturbances, assessed through the question: Do you have trouble falling asleep at night or do you wake up in the middle of the night? The primary outcome was mortality. We also dichotomized sleep disturbances into "never/sometimes" versus "usually" (frequently), and combined with the presence/absence of diabetes: 24.2% of participants reported "never/rarely" experiencing sleep disturbances, 47.8% "sometimes" and 28.0% "usually". In age- and sex-adjusted models, frequent sleep disturbances were associated with an increased risk of all-cause mortality (hazard ratio [HR], 1.31; 95% confidence interval [CI], 1.26-1.37), which remained significant in the fully adjusted model (HR 1.13, 95% CI 1.09-1.18). The presence of both diabetes and frequent sleep disturbances was associated with greater risk of all-cause mortality than either condition alone. In the fully adjusted model, the hazard ratio for all-cause mortality was 1.11 (95% CI, 1.07-1.15) for frequent sleep disturbances alone, 1.67 (95% CI, 1.57-1.76) for diabetes alone and 1.87 for both (95% CI, 1.75-2.01). Frequent sleep disturbances (experienced by more than one quarter of the sample) were associated with increased risk of all-cause mortality. Mortality risk was highest in those with both diabetes and frequent sleep disturbances. Complaints of difficulty falling or staying asleep merit attention by physicians.

We conducted a secondary analysis of the Mindfulness Sleep Therapy study, a randomized controlled trial testing Mindfulness-Based Therapy for Insomnia (MBTI) against a sleep hygiene education and exercise program (SHEEP). We investigated whether the interventions led to changes in sleep macroarchitecture (N2, N3 and REM), and microarchitecture (sleep fragmentation, slow wave activity, spectral band power) measured by ambulatory polysomnography (PSG).48 MBTI and 46 SHEEP participants provided usable PSG and subjective sleep quality data both pre- and post intervention. The interventions consisted of 8 weekly 2-hour group sessions, and daily practice. PSG data were staged according to the American Academy of Sleep Medicine criteria by 2 technicians blind to time point and condition. Repeated-measures ANOVA and permutation analysis were used to test for differences over time and between the interventions.Self-reported sleep quality improved in both study groups. We observed significant increases in N2 in MBTI but not SHEEP (p = .045), and significant increases in N3 in SHEEP but not MBTI (p = .012). No significant differences over time or between group were observed in N1, REM, or sleep fragmentation. Higher frequency non-REM EEG power decreased in SHEEP but not MBTI. Slow wave activity and slow wave activity dissipation did not differ over time or between groups. Among all variables, significant time by group interactions were observed in only N3 and non-REM alpha power.MBTI and sleep hygiene education had different effects on sleep macro and microarchitecture, suggesting that the underlying mechanisms of mindfulness training in improving sleep quality may differ from traditional interventions.

Cognitive-behavioral therapy for insomnia (CBT-I) has emerged as the first-line treatment for chronic insomnia but remains massively underused relative to the prevalence of insomnia disorder. This article focuses on 3 key issues in the delivery of CBT-I in the real world. First, where and how should CBT-I be delivered and who should deliver it? Second, who is an appropriate candidate for CBT-I? Third, how do you measure quality care with CBT-I? These issues give rise to targets for future research aimed at improving the implementation science of CBT-I in the real world.

Objective Mindfulness-based interventions (MBI) have been shown to reduce subjective symptoms of insomnia but the effects on objective measures remain unclear. The purpose of this study was to examine sleep EEG microarchitecture patterns from a randomized controlled trial of Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Therapy for Insomnia (MBTI). Methods Sleep EEG spectral analysis was conducted on 36 participants with chronic insomnia (>6 months) randomized to 8-week MBSR, MBTI, or self-monitoring control (SM). Overnight polysomnography with 6-channel EEG was conducted at baseline, post-treatment, and 6-month follow-up. Spectral power averaged from channels C3/C4 across NREM epochs (excluding N1) was examined for within-group changes and relationships with self-report measures. Results Increases in absolute NREM beta (16–25 Hz) power were observed from baseline to post-treatment (p = .02, d = 0.53) and maintained at 6-month follow-up (p = .01, d = 0.57) in the combined MBI groups, and additionally in the gamma (25–40 Hz) range at follow-up for the MBTI group only. No significant changes in these frequency bands were observed for SM. Following mindfulness intervention, NREM beta was positively associated with Five-Facet Mindfulness (FFM) score (rho = 0.37, p = .091) and negatively associated with Insomnia Severity Index (rho = −0.43, p = .047). Conclusion These results in people with insomnia corroborate prior reports of increased high-frequency sleep EEG power associated with mindfulness training. This change in beta EEG pattern merits further evaluation as a potential marker of the effects of mindfulness meditation on sleep, especially given the paradoxical findings in the context of insomnia.

Research has shown that sleep is essential to our physical and mental well-being. In this chapter, the authors discuss the relationships between psychological functioning, stress, and sleep, demonstrating that sleep plays a key role in cognitive and emotional processes and mental health. They also illustrate how various psychological factors contribute to sleep disturbance and explore different relaxation techniques shown to improve sleep quality, including deep breathing, guided imagery, progressive muscle relaxation, and mindfulness meditation. Finally, the authors examine Mindfulness-Based Therapy for Insomnia, a pioneering intervention that integrates cognitive-behavioral therapy (CBT) and mindfulness training.

African Americans report higher rates of chronic stress compared to non-Hispanic Whites. Consequently, chronic stress contributes to disproportionately higher rates of poor health outcomes among African Americans. Mindfulness meditation is a well-established and studied strategy to reduce stress and potentially improve health outcomes. However, the practice of mindfulness meditation is largely underutilized in African American communities despite its potential health benefits. In this commentary, we will discuss the relevance of mindfulness interventions, limited research available, reasons for low representation, and cultural adaptations for mindfulness meditation in African American communities. We also provide additional strategies to guide future mindfulness research that target African Americans.

Study Objectives To investigate treatment models using cognitive behavioral therapy for insomnia (CBT-I) and positive airway pressure (PAP) for people with obstructive sleep apnea (OSA) and comorbid insomnia. Methods 121 adults with OSA and comorbid insomnia were randomized to receive CBT-I followed by PAP, CBT-I concurrent with PAP, or PAP only. PAP was delivered following standard clinical procedures for in-lab titration and home setup and CBT-I was delivered in four individual sessions. The primary outcome measure was PAP adherence across the first 90 days, with regular PAP use (≥4 h on ≥70% of nights during a 30-day period) serving as the clinical endpoint. The secondary outcome measures were the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) with good sleeper (PSQI 7) serving as the clinical endpoints. Results No significant differences were found between the concomitant treatment arms and PAP only on PAP adherence measures, including the percentage of participants who met the clinical endpoint. Compared to PAP alone, the concomitant treatment arms reported a significantly greater reduction from baseline on the ISI (p = .0009) and had a greater percentage of participants who were good sleepers (p = .044) and remitters (p = .008). No significant differences were found between the sequential and concurrent treatment models on any outcome measure. Conclusions The findings from this study indicate that combining CBT-I with PAP is superior to PAP alone on insomnia outcomes but does not significantly improve adherence to PAP.

STUDY OBJECTIVES: The purpose of this study was to evaluate the feasibility and acceptability of a novel cognitive behavioral therapy for hypersomnia (CBT-H) in people with central disorders of hypersomnolence and co-occurring depressive symptoms using a telehealth model for delivery and assessment. METHODS: Thirty-five adults with narcolepsy or idiopathic hypersomnia received a 6-session CBT-H delivered individually or in small groups using videoconferencing. The clinical impact of CBT-H was evaluated using the Patient Health Questionnaire, Patient-Reported Outcomes Measurement Information System measures, Epworth Sleepiness Scale, and other patient-reported outcomes collected online at baseline and posttreatment. Feasibility and acceptability of the intervention and telehealth model was also evaluated using qualitative data collected from exit interviews conducted through videoconferencing. RESULTS: Forty percent of the sample achieved a clinically significant baseline to posttreatment change in depressive symptoms (decrease in Patient Health Questionnaire ≥ 5), which is below the prespecified efficacy benchmark (50% of the sample). The prespecified benchmark for a minimal clinically important difference (Cohen’s d > 0.5) on other psychosocial measures was met only on the Patient-Reported Outcomes Measurement Information System global self-efficacy (d = 0.62) in the total sample. Qualitative data revealed enthusiasm for the accessibility of telehealth delivery and the usefulness of several cognitive and behavioral modules but also revealed opportunities to refine the CBT-H program. CONCLUSIONS: These findings indicate that this new CBT-H program can potentially reduce depressive symptoms and improve self-efficacy in people with central disorders of hypersomnolence. Furthermore, telehealth is a promising model for remote delivery and data collection to enhance participant accessibility and engagement.

Comorbid insomnia and sleep apnea (COMISA) are the most common co-occurring sleep disorders and present many challenges to clinicians. This review provides an overview of the clinical challenges in the management of patients with COMISA, with a focus on recent evidence regarding the evaluation and treatment of COMISA. Innovations in the assessment of COMISA have used profile analyses or dimensional approaches to examine symptom clusters or symptom severity that could be particularly useful in the assessment of COMISA. Recent randomized controlled trials have provided important evidence about the safety and effectiveness of a concomitant treatment approach to COMISA using cognitive-behavioral therapy for insomnia (CBT-I) with positive airway pressure (PAP). Furthermore, patient-centered considerations that integrate patient characteristics, treatment preferences, and accessibility to treatment in the context of COMISA are discussed as opportunities to improve patient care. Based on these recent advances and clinical perspectives, a model for using multidisciplinary, patient-centered care is recommended to optimize the clinical management of patients with COMISA.

Study Objectives Insomnia is common in older adults, and is associated with poor health, including cognitive impairment and cardio-metabolic disease. Although the mechanisms linking insomnia with these comorbidities remain unclear, age-related changes in sleep and autonomic nervous system (ANS) regulation might represent a shared mechanistic pathway. In this study, we assessed the relationship between ANS activity with indices of objective and subjective sleep quality in older adults with insomnia. Methods Forty-three adults with chronic insomnia and 16 age-matched healthy sleeper controls were studied. Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), objective sleep quality by electroencephalogram spectral components derived from polysomnography, and ANS activity by measuring 24-h plasma cortisol and norepinephrine (NE). Results Sleep cycle analysis displayed lower slow oscillatory (SO: 0.5–1.25 Hz) activity in the first cycle in insomnia compared to controls. In insomnia, 24-h cortisol levels were higher and 24-h NE levels were lower than controls. In controls, but not in insomnia, there was a significant interaction between NE level during wake and SO activity levels across the sleep cycles, such that in controls but not in insomnia, NE level during wake was positively associated with the amount of SO activity in the first cycle. In insomnia, lower 24-h NE level and SO activity in the first sleep cycle were associated with poorer subjective sleep quality. Conclusion Dysregulation of autonomic activity may be an underlying mechanism that links objective and subjective measures of sleep quality in older adults with insomnia, and potentially contribute to adverse health outcomes.

BACKGROUND: Cancer-related sleep disturbance is common and can adversely affect physical and mental health. Bright light (BL) therapy is a novel intervention that targets sleep by promoting circadian regulation. Emerging evidence suggests BL can improve sleep disturbance, symptom burden, and health-related quality of life in cancer and other populations; however, this research is limited. The present two-phase pilot study assessed the feasibility and preliminary intended effects of BL therapy on sleep in ovarian and endometrial cancer survivors, and explored biologic and chronobiologic factors that may underlie intervention effects. METHODS: In phase I, focus groups were conducted with 12 survivors and 9 gynecologic oncology clinicians to evaluate and gather feedback about the proposed study. In phase II, a pilot randomized controlled trial was conducted with 18 ovarian or endometrial cancer survivors who were randomized to 1:1 to receive 45 minutes of BL or dim light (DL) for 4 weeks. Participants wore wrist actigraphs, completed sleep diaries and self-report questionnaires, and provided blood, saliva, and urine samples at baseline (T1), post-intervention (T2), and 3-month follow-up (T3). RESULTS: Study procedures were modified according to focus group results. Enrollment, retention, and adherence were all ≥ 80%. Mixed-model ANOVAs demonstrated that the number of nighttime awakenings per actigraphy, and sleep quality, cognitive functioning, and depression per self-report trended towards improvements in the BL condition compared to the DL condition. These variables improved from T1 to T2 before returning to baseline at T3. Effect sizes were generally medium to large. CONCLUSIONS: Study findings suggest that BL therapy is feasible among ovarian and endometrial cancer survivors. It may be an effective, non-pharmacological approach to reduce sleep disturbance and symptom burden in this population.

This chapter provides an overview and clinical guide for the assessment and treatment of insomnia in women. Emphasis is given to evaluating sleep disturbances related to the menstrual cycle, pregnancy, and postpartum period. In addition, considerations for working with transgender individuals and sexual minorities are discussed. Non-pharmacological and pharmacological treatment options are reviewed with attention given to modifications, dosing, and timing that are particularly relevant to women’s health.

Background: The COVID-19 pandemic has had a negative impact on psychological health. Mindfulness training, which helps individuals attend to the present moment with a non-judgmental attitude, improves sleep and reduces stress in regular times, and may be relevant in mitigating harmful health consequences during acute crises. However, restrictions may necessitate this training being delivered online, rather than in in-person group settings. Methods: Data from an ongoing study were used for this retrospective equivalence trial. Participants were recruited (with no exclusion criteria) from enrollees in mindfulness courses at a local charity organization promoting mental wellness. Three groups were created, two that received their training during the period of the COVID-19 pandemic (in-person (N = 36) and videoconferencing (N = 38)), and a second control group of participants tested before the pandemic (N = 86). Primary outcomes were self-reported stress and sleep quality. Baseline levels, and changes in these variables due to mindfulness training were compared among the groups using analysis of covariance and two one-sided t-tests. Findings: Perceived stress and sleep quality did not differ significantly between groups at baseline. Mindfulness training significantly reduced stress in all three groups, and this effect was statistically equivalent for videoconferencing compared to in-person training. Sleep quality improved significantly in the pre-pandemic group, but in neither of the groups during the pandemic. Participants reported shorter times to initiate sleep following mindfulness training pre-pandemic, but not during the pandemic. Course attendance was high and equivalent across the online and comparison groups, and participants engaged in marginally more daily practice in the online condition. Interpretation: Online mindfulness training via videoconferencing may be a useful intervention for stress reduction but not sleep improvement during times when traditional in-person training is not feasible. Funding: This study was supported by start-up funding from Duke-NUS Medical School and the National University of Singapore to JL.

Objective This observational pilot study examined objective circadian phase and sleep timing in chronic migraine (CM) and healthy controls (HC) and the impact of circadian factors on migraine frequency and severity. Background Sleep disturbance has been identified as a risk factor in the development and maintenance of CM but the biological mechanisms linking sleep and migraine remain largely theoretical. Methods Twenty women with CM and 20 age-matched HC completed a protocol that included a 7 day sleep assessment at home using wrist actigraphy followed by a circadian phase assessment using salivary melatonin. We compared CM vs HC on sleep parameters and circadian factors. Subsequently, we examined associations between dim-light melatonin onset (DLMO), the midpoint of the sleep episode, and the phase angle (time from DLMO to sleep midpoint) with the number of migraine days per month and the migraine disability assessment scale (MIDAS). Results CM and HC did not differ on measures of sleep or circadian phase. Within the CM group, more frequent migraine days per month was significantly correlated with DLMO (r = .49, P = .039) and later sleep episode (r = .47, P = .037). In addition, a greater phase angle (ie, circadian misalignment) was significantly correlated with more severe migraine-related disability (r = .48, P = .042). These relationships remained significant after adjusting for total sleep time. Conclusions This pilot study revealed that circadian misalignment and delayed sleep timing are associated with higher migraine frequency and severity, which was not better accounted for by the amount of sleep. These findings support the plausibility and need for further investigation of a circadian pathway in the development and maintenance of chronic headaches. Specifically, circadian misalignment and delayed sleep timing could serve as an exacerbating factor in chronic migraines when combined with biological predispositions or environmental factors.

Mindfulness-based interventions (MBI) have been shown to improve sleep quality among people with insomnia. However, much less is known about the effects of MBIs on other aspects of insomnia such as daytime symptoms and cognitive-emotional arousal. The purpose of this study was to examine the treatment effects on these domains for adults with chronic insomnia disorder who were randomized to mindfulness-based stress reduction (MBSR), mindfulness-based therapy for insomnia (MBTI), or a delayed-treatment control consisting of sleep diary self-monitoring (SM) followed by behavior therapy (BT). Analyses were conducted on baseline to post-treatment changes with superiority comparisons for each MBI to SM followed by non-inferiority comparisons for each MBI to BT. The results revealed significant reductions from baseline in the MBTI group with large effect sizes on sleep effort, maladaptive sleep-related cognitions, and hyperarousal which were superior to the SM control (p

Introduction Light avoidance is a common coping behavior of individuals with migraine headaches. It is not known whether timing of light exposure is different in individuals with chronic migraine (CM) compared to those without migraine and how this may relate to headache frequency and severity. We tested this by examining timing of the brightest and darkest light and headaches in women with chronic migraines and healthy controls. Methods Sixteen women with CM (mean age = 33.07) and 18 female healthy controls (HC; mean age = 32.22) completed daily ratings of headache severity (0-10, severity > 2 classified as headache) concurrent with light exposure measured by wrist actigraphy for approximately one month (M=28.00 days, range=21-36). Start time of each day’s 10-hour periods of maximum light (M10) and 5-hour periods of lowest light (L5) were calculated and averaged for each participant. T-tests and Cohen’s d effect sizes were used to compare groups. Pearson correlation coefficients were calculated to examine associations between M10/L5 timing and headache frequency and severity. Results M10 was earlier in the CM group compared to the HC group (07:42±00:47 vs. 08:50±00:58, t(32)=3.69, p=0.0008, d=1.08). The CM group exhibited non-significant trend towards earlier L5 compared to the HC group (12:26±00:48 vs. 01:07±01:03, t(32)=1.89, p=0.0723, d=0.62). Among individuals with CM, later M10 timing was associated with more severe average daily headache (r=0.60, p=0.0136) and more frequent headaches (r=0.55, p=0.0257). Later L5 timing was significantly associated with more severe average daily headache (r=0.66, p=0.0052) and showed a non-significant trend toward association with more frequent headaches (r=0.47, p=0.0686). Conclusion Timing of the greatest light exposure period was earlier in CM compared to HC. Within the CM group, those who had earlier light and dark periods reported lower headache severity and fewer days with headaches. These findings suggest the possibility of a role for the circadian system in chronic migraine. Support This study was supported by grant R21NS081088 from the National Institutes of Health.

Introduction The purpose of this study was to conduct a feasibility trial for a novel cognitive behavioral therapy (CBT-H) aimed at improving health-related quality of life (HRQoL) in people with hypersomnia. Methods Participants were 35 adults (32 female, mean age=32.0 years, SD=12.9) with an established diagnosis of Narcolepsy Type 1 (n=12), Type 2 (n=11), or Idiopathic Hypersomnia (n=12). Participants were assigned to individual (n=19) or group (n=16, 3-5 per group) format of a 6-session, manualized CBT-H, delivered using live videoconferencing. Key components of CBT-H included structuring daytime behaviors (e.g., planned naps), emotion regulation techniques, and energy management strategies. Outcome measures for HRQoL included PROMIS measures for depression, anxiety, self-efficacy, and social isolation. Other clinical outcome measures included the Patient Health Questionnaire (PHQ) and Epworth Sleepiness Scale (ESS). Exit interviews were used to collect qualitative data to inform acceptability of the intervention. Results Intent-to-treat analyses were conducted on the entire sample with the last observation carried forward for 3 participants who did not provide post-treatment data. Paired-samples t-test revealed a significant reduction on PROMIS depression (t[34]=2.05, p=0.0486, d=-0.35), and significant increases on PROMIS general self-efficacy (t[34]=3.64, p=0.0009, d=0.62) and self-efficacy managing social interactions (t[34]=2.14, p=0.0396, d=0.36). Significant reductions were also observed on the ESS (t[34]=2.07, p=0.0458, d=-0.35) and PHQ (t[34]=4.42, p Conclusion These findings support the acceptability of a novel CBT-H delivered using a telehealth model and the feasibility of reducing excessive sleepiness and improving HRQoL, particularly in the domains of self-efficacy and depression, in people with narcolepsy and idiopathic hypersomnia.

BACKGROUND: Insomnia and depression are highly prevalent perinatal complications. Ruminating on stress is etiologically implicated in both disorders, and ruminating while trying to fall asleep has been linked to insomnia and depression during pregnancy. Incompatible with rumination is everyday mindfulness, i.e., living with intentional and nonjudgmental awareness of internal and external experiences in the present moment. Responding to stress mindfully may protect against stress-related perinatal complications such as insomnia and depression. The present study described the association between everyday mindfulness and nocturnal rumination, and examined whether these trait characteristics were independently related to perinatal insomnia and depression. METHODS: Cross-sectional and secondary analysis of existing data from 65 pregnant women recruited from a multisite hospital in Metro Detroit, MI, USA. Subjects completed online surveys including the Insomnia Severity Index, Edinburgh Postnatal Depression Scale, Presleep Arousal Scale, and the revised Cognitive and Affective Mindfulness Scale. RESULTS: Over half (53.8%) of women screened positive for clinical insomnia and 12.3% screened positive for major depression. Women high in mindfulness, relative to those low in mindfulness, reported less nocturnal rumination (Cohen’s d=1.16), insomnia symptoms (Cohen’s d=1.24), and depressive symptoms (Cohen’s d=1.35). Multivariate linear regression revealed that both mindfulness (β=−.24, p=.03) and rumination (β=.38, p

Cognitive-behavioral therapy for insomnia (CBT-I) has emerged as the first-line treatment for chronic insomnia but remains massively underused relative to the prevalence of insomnia disorder. This article focuses on 3 key issues in the delivery of CBT-I in the real world. First, where and how should CBT-I be delivered and who should deliver it? Second, who is an appropriate candidate for CBT-I? Third, how do you measure quality care with CBT-I? These issues give rise to targets for future research aimed at improving the implementation science of CBT-I in the real world.

Background: The decelerated increase in life expectancy in the UK suggests an imperative for identifying modifiable contributing factors. Partly to blame are non-communicable diseases, such as diabetes, which have been associated with disturbed or insufficient sleep. Methods: Data from the UK Biobank were analysed (mean follow-up time: 6.5 years). Primary exposure was insomnia symptoms, assessed through the single question "Do you have trouble falling asleep at night or do you wake up in the middle of the night?". Primary outcome was mortality. We dichotomized insomnia symptoms into "never/sometimes" (infrequent) vs "usually" (frequent) and combined this with presence/absence of diabetes to create four groups. Findings: 24.2% of participants reported "never/rarely" experiencing insomnia symptoms, 47.8% answered "sometimes" and 28.0% "usually". On average, those reporting frequent insomnia symptoms were older, had a higher BMI, slept less, and were more likely to be female, white, current smokers, and have depression and diabetes. In age- and sex-adjusted models, frequent insomnia symptoms were associated with increased risk of all-cause mortality (HR 1.36, 95% CI 1.30-1.43), which remained significant in the fully-adjusted model (HR 1.20, 95% CI 1.14-1.26). Presence of either frequent insomnia symptoms or diabetes was associated with increased risk of all-cause mortality. In the fully adjusted model, the hazard ratio for all-cause mortality was 1.16 (95% CI 1.11-1.21) for frequent insomnia symptoms alone, 1.67 (95% CI 1.55-1.79) for diabetes alone and 2.03 for both (95% CI 1.86-2.21). Interpretation: We observed significant associations between frequent insomnia symptoms (present in more than one quarter of the sample) and risk of all-cause mortality. This increased mortality was exacerbated by diabetes. Although symptoms covered by the question could reflect other underlying morbidity, complaints of difficulty falling or staying asleep were associated with mortality, and therefore merit attention by physicians.

Importance: Digital cognitive behavioral therapy (dCBT) is a scalable and effective intervention for treating insomnia. Most people with insomnia, however, seek help because of the daytime consequences of poor sleep, which adversely affects quality of life. Objectives: To investigate the effect of dCBT for insomnia on functional health, psychological well-being, and sleep-related quality of life and to determine whether a reduction in insomnia symptoms was a mediating factor. Design, Setting, and Participants: This online, 2-arm, parallel-group randomized trial comparing dCBT for insomnia with sleep hygiene education (SHE) evaluated 1711 participants with self-reported symptoms of insomnia. Participants were recruited between December 1, 2015, and December 1, 2016, and dCBT was delivered using web and/or mobile channels plus treatment as usual; SHE comprised a website and a downloadable booklet plus treatment as usual. Online assessments took place at 0 (baseline), 4 (midtreatment), 8 (posttreatment), and 24 (follow-up) weeks. Programs were completed within 12 weeks after inclusion. Main Outcomes and Measures: Primary outcomes were scores on self-reported measures of functional health (Patient-Reported Outcomes Measurement Information System: Global Health Scale; range, 10-50; higher scores indicate better health); psychological well-being (Warwick-Edinburgh Mental Well-being Scale; range, 14-70; higher scores indicate greater well-being); and sleep-related quality of life (Glasgow Sleep Impact Index; range, 1-100; higher scores indicate greater impairment). Secondary outcomes comprised mood, fatigue, sleepiness, cognitive failures, work productivity, and relationship satisfaction. Insomnia was assessed with the Sleep Condition Indicator (range: 0-32; higher scores indicate better sleep). Results: Of the 1711 participants included in the intention-to-treat analysis, 1329 (77.7%) were female, mean (SD) age was 48.0 (13.8) years, and 1558 (91.1%) were white. Use of dCBT was associated with a small improvement in functional health compared with SHE (adjusted difference [95% CI] at week 4, 0.90 [0.40-1.40]; week 8, 1.76 [1.24-2.28]; week 24, 1.76 [1.22-2.30]) and psychological well-being (adjusted difference [95% CI] at week 4, 1.04 [0.28-1.80]; week 8, 2.68 [1.89-3.47]; week 24, 2.95 [2.13-3.76]), and with a large improvement in sleep-related quality of life (at week 4, -8.76 [-11.83 to -5.69]; week 8, -17.60 [-20.81 to -14.39]; week 24, -18.72 [-22.04 to -15.41]) (all P Conclusions and Relevance: Use of dCBT is effective in improving functional health, psychological well-being, and sleep-related quality of life in people reporting insomnia symptoms. A reduction in insomnia symptoms mediates these improvements. These results confirm that dCBT improves both daytime and nighttime aspects of insomnia, strengthening existing recommendations of CBT as the treatment of choice for insomnia.

Objective Spousal bereavement is linked to increased mortality and morbidity from inflammatory conditions. It also has a significant impact on sleep disturbances. Evidence from experimental studies indicates that chronic stress may prime individuals to have an exaggerated inflammatory response to acute stress. In this study, we examined the association between self-reported sleep disturbances and inflammation after adjusting for depressive symptoms and determined whether this association varies by bereavement status (bereaved individuals versus controls). Methods Participants included 54 bereaved individuals and 47 controls with a M (SD) age of 67.12 (12.11) years. Inflammation was measured using C-reactive protein. Self-reported sleep disturbances were measured using the Pittsburgh Sleep Quality Index. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale. Results Sleep disturbances were not associated with elevated levels of C-reactive protein in the overall group (B = 0.030, standardized β = 0.122, 95% confidence interval [CI] = -0.027 to 0.087, p = .299) after adjusting for depressive symptoms. Results indicated, however, that bereavement moderated the association between inflammation and sleep disturbances (B = 0.104, β = 0.517, 95% CI = 0.009 to 0.198, p = .032). Stratified analyses demonstrated that these associations differed across groups. Associations were significant among bereaved individuals (B = 0.104, β = 0.406, 95% CI = 0.013 to 0.196, p = .026) and not controls (B = -0.016, β = -0.066, 95% CI = -0.096 to 0.065, p = .690). Conclusions These findings provide preliminary evidence that bereavement moderates the association between self-reported sleep disturbances and inflammation. Future studies should examine the course of sleep disturbances after bereavement and establish whether objective sleep has differential associations with inflammation among bereaved adults.

Chronic insomnia disorder is a prevalent condition and a significant proportion of these individuals also have obstructive sleep apnea (OSA). These two sleep disorders have distinct pathophysiology and are managed with different treatment approaches. High comorbidity rates have been a catalyst for emerging studies examining multidisciplinary treatment for OSA comorbid with insomnia disorder. In this article, we describe a randomized clinical trial of Cognitive Behavioral Treatment for insomnia (CBT-I) and Positive Airway Pressure (PAP) for OSA. Participants are randomized to receive one of three treatment combinations. Individuals randomized to treatment Arm A receive sequential treatment beginning with CBT-I followed by PAP, in treatment Arm B CBT-I and PAP are administered concurrently. These treatment arms are compared to a control condition, treatment Arm C, where individuals receive PAP alone. Adopting an incomplete factorial study design will allow us to evaluate the efficacy of multidisciplinary treatment (Arms A & B) versus standard treatment alone (Arm C). In addition, the random allocation of individuals to the two different combined treatment sequences (Arm A and Arm B) will allow us to understand the benefits of the sequential administration of CBT-I and PAP relative to concurrent treatment of PAP and CBT-I. These findings will provide evidence of the clinical benefits of treating insomnia disorder in the context of OSA.

Introduction Poor sleep is a modifiable risk factor for multiple chronic disorders. Mindfulness-based therapies potentially improve sleep by enhancing awareness and acceptance of internal and external experiences, thus reducing pre-sleep hyper-arousal. In this pre-registered, randomized controlled trial, we tested the effect of mindfulness-based treatment for insomnia (MBTI) on subjective sleep quality measures (Pittsburgh Sleep Quality Questionnaire, PSQI) in the elderly. Methods Participants above 50 years old with sleep difficulties (PSQI ≥ 5) (mean (sd) age = 62.0 (6.35), 44 female) attended either an 8-week MBTI (N = 34) or sleep hygiene education and exercise program (SHEEP; N = 35). Before and after the interventions, we collected PSQI, insomnia symptoms and features measures (Pre-Sleep Arousal Scale, PSAS; Insomnia Severity Index, ISI; Dysfunctional Beliefs and Attitudes about Sleep, DBAS-30), mindfulness (Five-Facets Mindfulness Questionnaire, FFMQ), and mood and anxiety (Back Depression Inventory, BDI; State-Trait Anxiety Inventory, STAI). PSQI and PSAS (N = 26 to date) were collected at 6-month follow-up. Data were analysed with repeated-measures ANCOVA with group as a between-subject variable for the first 69 participants who completed the study. Results We observed significant improvement across both groups for sleep measures (PSQI: F1,67=36.442, p Conclusion Preliminary results support MBTI as an accessible but effective behavioural intervention with potential long-term benefits for improving sleep and mood, and reducing cognitive-emotional arousal in the elderly.

Introduction This study examines the effects of treatment sequences using cognitive-behavioral therapy for insomnia (CBT-I) and continuous positive airway pressure (CPAP) therapy on daytime functioning in people with comorbid insomnia and sleep apnea (COMISA). Methods 118 participants with COMISA (Age=49.99±13.12; 53.4% female) were randomized to one of the three study arms: Arm A- CBT-I followed by CPAP, Arm B- CBT-I concurrent with CPAP, and Arm C- CPAP only. Participants were assessed at four time points [baseline/ start of phase 1 (A1), CPAP titration/ start of phase 2 (A2), 30 days (A3) and 90 days (A4) after CPAP initiation]. This study examined secondary outcome measures of daytime functioning, including the Functional Outcomes of Sleep Questionnaire (FOSQ), Epworth Sleepiness Scale, and Flinders Fatigue Scale (FFS). Results Linear mixed model analyses showed a main effect of time on improving functional outcomes in all measurements, with all p< 0.001. There were also arm by time interactions on FOSQ [F(6, 105.36)=4.21, p=0.001] and FFS scores [F(6, 106.95)=3.10, p=0.008]. Pairwise comparisons with Bonferroni adjustment showed improved FOSQ scores in Arm A from A1 to A2 (p=0.011) and A2 to A3 (p=0.005), Arm B from A2 to A3 (p< 0.001), and Arm C from A2 to A3 (p=0.006). For FFS scores, improvements were shown in Arm A from A1 to A2 (p=0.003), and Arm B from A2 to A3 (p < 0.001). Conclusion The results show daytime functioning improvements in patients with COMISA following CPAP and CBT-I. In addition, CBT-I appears to facilitate improvement in sleepiness-related functional status and daytime fatigue. The findings suggest that the combination of CBT-I and CPAP may have a beneficial effect on daytime functioning in patients with COMISA.

The goal of this review is to provide an update on the use of mindfulness meditation for the treatment of insomnia, including conceptual models and empirical evidence from randomized controlled trials.A metacognitive model of insomnia has been proposed as a conceptual model to explain the application of mindfulness principles for reducing insomnia-related arousal. Furthermore, the evidence base for mindfulness-based therapies has grown with the results of several randomized controlled trials published in the past three years. Treatment effects appear to be strongest on self-report measures compared to objective measures of sleep.Treatment programs featuring mindfulness meditation appear to be viable treatment options for people with insomnia. Further research is needed to determine who is likely to benefit from mindfulness-based therapies and how these interventions work. Additionally, further work is needed to resolve issues related to the delivery and implementation of mindfulness-based therapies.

OBJECTIVE The aim was to describe the early phases of the progressive development of a lifestyle treatment for sustained remission of the metabolic syndrome (MetS) using the Obesity-Related Behavioral Intervention Trials (ORBIT) model for behavioral treatment development as a guide. METHODS Early discovery and design phases produced a 3-component (diet, physical activity, stress), group-based lifestyle treatment with an intensive 6-month phase followed by monthly, participant-led maintenance meetings. In the proof-of-concept phase, 26 participants with the MetS (age 53 ± 7 years, 77% female, and 65% ethnic minority) were recruited in a quasi-experimental design to determine if treatment could achieve the prespecified benchmark of MetS remission in ≥50% at 2.5 years. Exploratory outcomes focused on MetS components, weight, and patient-centered benefits on energy/vitality and psychosocial status. RESULTS MetS remission was achieved in 53.8% after a median of 2.5 years. At 2.5 years, an increase of +15.4% reported eating ≥3 servings of vegetables/day, +7.7% engaged in ≥150 minutes of moderate-to-vigorous physical activity/week; and +11.5% reported experiencing no depression in the past 2 weeks. Weight loss ≥5% was achieved by 38.5%, and energy/vitality, negative affect, and social support improved. Median group attendance over 2.5 years was 73.8%. CONCLUSIONS It is plausible that this lifestyle program can produce a remission in the MetS, sustained through 2.5 years. After refinements to enhance precision and strength, progression to feasibility pilot testing and a randomized clinical trial will determine its efficacy as a cost-effective lifestyle option for managing the MetS in the current health care system.
