OBJECTIVE: Poor sleep is associated with increased inflammation, thereby increasing the risk of chronic diseases and mortality. However, the effects of behavioral sleep interventions on the upstream inflammatory system are unknown among family care partners (CP). The present study explored the role of a behavioral sleep intervention program on inflammatory gene expression. METHODS: This was part of a randomized controlled trial of a sleep intervention for dementia care dyads with sleep problems. Thirty dyads were randomized to sleep intervention or control groups. Sleep outcomes for CP were assessed with 1 week of actigraphy and sleep diary, and the Pittsburgh Sleep Quality Index. Other information included CP demographics, body mass index, and intensity of caregiving tasks. All outcomes were collected at baseline, post-treatment, and 3-month follow-up. RESULTS: Neither group showed any significant differential changes in gene expression from baseline to post-treatment or 3-month follow-up. A decrease in inflammatory gene expression was significantly associated with more nights of good sleep (i.e. nights without trouble falling or staying asleep at night). This finding remained significant after controlling for group (intervention/control), timepoint (baseline, post-treatment, and 3-month follow-up), and CP characteristics (e.g. age and ethnicity). CONCLUSIONS: Although better sleep was associated with decreased inflammatory gene expression, this study did not demonstrate any benefits of a behavioral sleep intervention over control, most likely due to a small sample. Studies with larger sample sizes are needed to test the specific aspects of disturbed sleep that relate to inflammatory biology among CP of persons living with dementia.

BACKGROUND: Obstructive sleep apnea (OSA) is highly prevalent in patients with Type 2 diabetes, more so in veterans compared with nonveterans. Positive airway pressure is the recommended first-line treatment for OSA. However, adherence to both positive airway pressure and diabetes management regimens can be challenging for older adults. Support from family or friends may improve glucose control or sleep-apnea-related symptoms, yet the evidence is limited when both conditions coexist. OBJECTIVES: This study aimed to describe veterans experiences of support from family and friends with managing comorbid sleep apnea and Type 2 diabetes. METHODS: We conducted a postal survey of older veterans with OSA and Type 2 diabetes from one healthcare system. Questions include demographic and health-related information, information about sleep apnea and diabetes treatment and education received, related support from family or a friend, perceived benefits of regular positive airway pressure device use on improving sleep health, and perceived benefits of education for family or a friend on sleep apnea and diabetes. Descriptive and bivariate analyses were performed. RESULTS: Of 145 respondents (mean age = 72 years), 43% reported receiving help for Type 2 diabetes from family or a friend. Almost two thirds of the respondents were currently using a positive airway pressure device, of whom 27% received support with device use from family or friends. About one third of veterans perceived family and friends receiving education on treating sleep apnea and diabetes to be very or extremely helpful. Such perceived benefit was higher among those who were married or identified as non-White. Veterans using a positive airway pressure device had lower hemoglobin A1c levels than nonusers. DISCUSSION: Veterans perceived that additional education for the individuals providing support would be beneficial. Future studies could address interventions to increase sleep apnea and Type 2 diabetes knowledge among families and friends of veterans with these comorbid conditions. In addition, patients adherence to positive airway pressure may be enhanced by support from family and friends.

PURPOSE: Sleep-disordered breathing (SDB) is a common sleep disorder in veterans; however, limited research exists in women veterans. We sought to estimate patterns of care in terms of evaluation, diagnosis, and treatment among women veterans with factors associated with elevated SDB risk. METHODS: Within one VA healthcare system, women identified through electronic health record data as having one or more factors (e.g., age >50 years, hypertension) associated with SDB, completed telephone screening in preparation for an SDB treatment study and answered questions about prior care related to SDB diagnosis and treatment. RESULTS: Of 319 women, 111 (35%) reported having completed a diagnostic sleep study in the past, of whom 48 (43%) were diagnosed with SDB. Women who completed a diagnostic study were more likely to have hypertension or obesity. Those who were diagnosed with SDB based on the sleep study were more likely to have hypertension, diabetes, or be ≥50 years old. Of the 40 women who received treatment, 37 (93%) received positive airway pressure therapy. Only 9 (24%) had used positive airway pressure therapy in the prior week. Few women received other treatments such as oral appliances or surgery. CONCLUSIONS: Findings support the need for increased attention to identification and management of SDB in women veterans, especially those with conditions associated with elevated SDB risk.

Although delirium detection and prevention practices are recommended in critical care guidelines, there remains a persistent lack of effective delirium education for ICU providers. To address this knowledge-practice gap, we developed an "ICU Delirium Playbook" to educate providers on delirium detection (using the Confusion Assessment Method for the ICU) and prevention.DesignBuilding on our previous ICU Delirium Video Series, our interdisciplinary team developed a corresponding quiz to form a digital "ICU Delirium Playbook." Playbook content validity was evaluated by delirium experts, and face validity by an ICU nurse focus group. Additionally, focus group participants completed the quiz before and after video viewing. Remaining focus group concerns were evaluated in semi-structured follow-up interviews.SettingOnline validation survey, virtual focus group, and virtual interviews.SubjectsThe validation group included six delirium experts in the fields of critical care, geriatrics, nursing, and ICU education. The face validation group included nine ICU nurses, three of whom participated in the semi-structured feedback interviews.InterventionsNone.Measurements and main resultsThe 44-question quiz had excellent content validity (average scale-level content validity index [S-CVI] of individual items = 0.99, universal agreement S-CVI = 0.93, agreement κ ≥ 0.75, and clarity p ≥ 0.8). The focus group participants completed the Playbook in an average (sd) time of 53 (14) minutes, demonstrating significant improvements in pre-post quiz scores (74% vs 86%; p = 0.0009). Verbal feedback highlighted the conciseness, utility, and relevance of the Playbook, with all participants agreeing to deploy the digital education module in their ICUs.ConclusionsThe ICU Delirium Playbook is a novel, first-of-its-kind asynchronous digital education tool aimed to standardize delirium detection and prevention practices. After a rigorous content and face validation process, the Playbook is now available for widespread use.

OBJECTIVES: Poor sleep is common among older adults with chronic health conditions and their spousal caregivers. However, dyadic sleep patterns among spouses are underexplored within the literature. This study examines dyadic sleep characteristics and associated contextual factors among spousal care dyads. METHODS: Participants included 462 older adult spousal care dyads from the 2015 National Health and Aging Trends Study and National Study of Caregiving (mean ages of care recipients/caregivers = 79 and 76 years, respectively; 22% of dyads were living with dementia). Self-reported sleep included frequency of (a) trouble falling back asleep among dyads, (b) care-related sleep disturbances among caregivers, and (c) trouble initiating sleep among care recipients. Predictors included between-dyad characteristics such as whether respondents had dementia, care burden and support, relationship quality, neighborhood cohesion, and within-dyad characteristics such as demographics, depression, and positive affect. We conducted multilevel dyadic analysis and actor-partner interdependence modeling. RESULTS: Sleep was correlated more among dyads living with dementia than those with other chronic conditions. Care dyads had poorer sleep if caregivers reported higher care burden; however, better relationship quality marginally ameliorated the association. Depressive symptoms had a partner effect on poorer sleep among care dyads, whereas positive emotions and older age only had an actor effect on better sleep for care recipients and spousal caregivers. Neighborhood cohesion, care support, and other demographic characteristics were not associated with dyadic sleep outcomes. DISCUSSION: Addressing both care recipient- and caregiver-related factors may improve sleep health for both members of the care dyad living with chronic conditions.

Study objectivesPoor sleep, including short sleep duration, is common among caregivers of persons with dementia. However, it is unclear whether poor sleep is consistent across both self-reported and objective measures of sleep in caregivers. This study aimed to test the role of caregiving status (caregivers vs noncaregivers) on the discrepancy between self-reported and objective sleep duration.MethodsThis was a cross-sectional study. Study participants were community-dwelling caregivers of spouses with dementia (n = 122) and noncaregivers (n = 53). A sleep duration discrepancy index was created by subtracting objective sleep duration measured with 3 consecutive 24-hour periods of actigraphy from self-reported sleep duration measured with the Pittsburgh Sleep Quality Index. Covariates included participants' demographic characteristics, depressive symptoms, positive and negative affects, personal mastery, and caregiving-role overload.ResultsCaregivers showed a greater discrepancy in sleep duration than did noncaregivers (-0.46 hour vs 0.22 hour, respectively; P = .003). In a regression model, however, caregiving status was no longer associated with this sleep duration discrepancy, when covariates were accounted for. Higher positive affect was significantly associated with less sleep duration discrepancy (R2 = 11.3%, P = .014). The Sobel test of mediation showed that 26% of the effect of caregiving on this sleep discrepancy was attributable to caregivers with low positive affect.ConclusionsThe findings suggest a potential mediating role of positive affect on the relationship between caregiving status and sleep duration discrepancy. As an aid for understanding the role of lower positive affect, use of actigraphy may help address sleep discrepancy in caregivers.CitationSong Y, Moore RC, Jeste DV, et al. Discrepancy between self-reported and objective sleep duration among dementia caregivers and noncaregivers. J Clin Sleep Med. 2022;18(8):1945-1952.

Despite poor sleep among older adults, little is known about the sleep habits of older immigrants living in the United States. The current pragmatic qualitative descriptive study explored sleep among older Korean immigrants, using a focus group with six participants and individual phone interviews with 22 Korean immigrants aged ≥60 years. Transcripts were coded to identify underlying themes. Several thematic categories were identified under six domains: daytime function, getting ready for bed, falling asleep, awakenings during sleep, going back to sleep, and seeking advice from peers. Unhealthy sleep behaviors were found during daytime and bedtime, particularly among those who were retired/unemployed or living alone. Seeking advice from peers was common but none of the advice helped participants sleep. Sleep education programs in Korean-speaking communities can be used to target those who are socially isolated and may benefit older Korean immigrants with sleep difficulties.

IntroductionCigarette smoking is strongly associated with the development of cardiovascular disease (CVD). However, evidence is limited as to whether smokeless tobacco (ST) use is associated with CVD.Aims and methodsUsing data from 4347 adults in the Population Assessment of Tobacco and Health Study (2013-2014), we compared geometric mean concentrations of CVD-related harm biomarkers and biomarkers of exposure among exclusive ST users and exclusive cigarette smokers-in relation to recent nicotine exposure-and never tobacco users, adjusting for age, sex, race/ethnicity, income, body mass index, and CVD. Biomarker levels among exclusive ST users who were former established cigarette smokers were compared with exclusive cigarette smokers.ResultsCompared with cigarette smokers, ST users had significantly higher concentrations of total nicotine equivalents (TNE) but lower concentrations of inflammatory (high-sensitivity C-reactive protein, interleukin-6, intercellular adhesion molecule, fibrinogen) and oxidative stress (8-isoprostane) biomarkers (all p < .05). Biomarker levels among ST users were similar to never smokers. ST users who were former cigarette smokers had lower levels of inflammatory and oxidative stress biomarkers and biomarkers of exposure (cadmium, lead, 1-hydroxypyrene, acrylonitrile, and acrolein), compared with cigarettes smokers (p < .05), despite having higher TNE levels (p < .05). Among cigarette smokers, but not among ST users, inflammatory biomarkers and TNE were highly correlated.ConclusionsST use is not associated with increases in biomarkers of CVD-related harm and exposure, compared with never smokers, despite exposure to nicotine at levels higher than those observed among cigarette smokers. These findings support the concept that increases in CVD risk among cigarette smokers is caused primarily by constituents of tobacco smoke other than nicotine.ImplicationsDespite having higher levels of nicotine and compared with exclusive cigarette smokers, exclusive ST users (including those who were former cigarette smokers) had significantly lower concentrations of inflammatory and oxidative stress biomarkers, comparable to levels observed among never tobacco users. These findings suggest that increases in CVD risk among cigarette smokers is caused primarily by tobacco constituents other than nicotine and that switching to ST is likely associated with lower CVD risk.

Poor sleep is common among older adults, affecting a wide range of health outcomes. However, little is known about sleep issues among older Korean immigrants, the fastest growing Asian American subgroup in the United States. We aimed to explore multiple factors associated with sleep among this group. We analyzed cross-sectional survey data from 43 older immigrants living in two large Korean communities in Southern California. Perceived sleep quality was significantly associated with gender, living arrangement, employment status, mental health, and sleep-related beliefs (all p-values

Hypertension is a key driver of cardiovascular diseases. However, how stressors contribute to the development of hypertension remains unclear. The objective of this study was to examine prospective associations of adverse childhood experiences (ACEs) and adulthood psychosocial disadvantages (APDs) with incident hypertension. Data were from the Mid-life in the United States (MIDUS) study, a national, population-based, prospective cohort study. ACEs were examined via retrospective reports, and APDs including work stress and social isolation were assessed using survey measures. Incident hypertension was defined based on self-reported physician diagnosis. Baseline data were collected in 1995, with follow-up in 2004-2006 and 2013-2014. Cox proportional hazards regression was applied to assess prospective associations of ACEs and APDs with incident hypertension in 2568 workers free from hypertension at baseline. After adjustment for covariates, baseline APDs were associated with increased incident hypertension (aHR and 95% CI = 1.48 [1.09, 2.01]) during a 20-year follow-up, whereas ACEs showed null associations. Moreover, a moderating effect by ACEs was observed-the effect of APDs on risk of hypertension was stronger when ACEs were present (aHR and 95% CI = 1.83 [1.17, 2.86]). These findings underscore the importance of psychosocial stressors as nontraditional risk factors of cardiometabolic disorders.

Nearly 350,000 lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ+) adults in the U.S. are currently living with Alzheimer's disease and related dementias (ADRD). Informal caregivers face challenges impacting their ability to access and receive adequate and inclusive care for LGBTQ+ persons living with ADRD. The purpose of this study was to determine the feasibility and acceptability of the Savvy Caregiver Program for caregivers of LGBTQ+ individuals living with ADRD. Data for this secondary analysis come from caregivers (n = 17) who completed 6 sessions of the Savvy program. Caregivers were very satisfied with tailored program activities. Analyses of trends suggest non-significant increases in positive aspects of caregiving and decreases in caregiver burden and depressive symptoms. This is the first known study assessing the feasibility of the Savvy Caregiver Program for caregivers of LGBTQ+ individuals living with ADRD. Future research on the Savvy Caregiver Program for caregivers of LGBTQ+ people living with ADRD is needed.

BackgroundCognitive behavioral therapy for insomnia (CBTI) targets changing dysfunctional sleep-related beliefs. The impact of these changes on daytime functioning in older adults is unknown.PurposeWe examined whether changes in sleep-related beliefs from pre- to post-CBTI predicted changes in sleep and other outcomes in older adults.MethodData included 144 older veterans with insomnia from a randomized controlled trial testing CBTI. Sleep-related beliefs were assessed with the Dysfunctional Beliefs and Attitudes about Sleep-16 (DBAS-16, subscales: Consequences, Worry/Helplessness, Sleep Expectations, Medication). Outcomes included sleep diary variables, actigraphy-measured sleep efficiency, Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Flinders Fatigue Scale (FFS), Patient Health Questionnaire-9, and health-related quality of life. Analyses compared slope of change in DBAS subscales from baseline to posttreatment between CBTI and control, and assessed the relationship between DBAS change and the slope of change in outcomes from baseline to 6 months.ResultsCompared to controls, the CBTI group demonstrated stronger associations between improvement in DBAS-Consequences and subsequent improvement in PSQI, ISI, ESS, and FFS. The CBTI group also demonstrated stronger associations between improvement in DBAS-Worry/Helplessness and subsequent improvements in PSQI, ISI, and FFS; improvements in DBAS-Medication and PSQI; and improvements in DBAS-Sleep Expectations and wake after sleep onset (sleep diary) and FFS (all p < .05).ConclusionsSignificant reduction in dysfunctional sleep-related beliefs following CBTI in older adults predicted improvement in several outcomes of sleep and daytime functioning. This suggests the importance of addressing sleep-related beliefs for sustained improvement with CBTI in older veterans.Trial registrationClinicalTrials.gov Identifier: NCT00781963.

PurposeThis study aimed to refine a behavioral sleep intervention program targeting patients with Alzheimer's disease and their caregivers.MethodsIn this case series, key components of the sleep program were built upon previous intervention studies of patients with cognitive impairment/dementia. The intervention consisted of five weekly sessions covering sleep hygiene, sleep compression, stimulus control, daily walking/light exposure, relaxation/mindfulness, and caregiver training to manage patients' behavioral problems. The materials and structure were iteratively refined based on feedback from caregivers and sleep educators. Sleep diaries were used to evaluate sleep outcomes.ResultsFive out of six enrolled dyads completed the sessions. Several revisions were made during testing: the last session was changed from telephone to in-person; some components (e.g., sleep scheduling, mindfulness) were rearranged within or across sessions; sleep educator guidelines for sleep scheduling, light exposure, and walking were revised. After the fifth dyad, no additional issues were identified by the caregiver or the sleep educator. Four patients and three caregivers had improved sleep at the last session.ConclusionsThe iterative refinement process was successful in finalizing the intervention program, with evidence of sleep improvements. Formal pilot testing of the program will provide further information on feasibility and effectiveness.IMPLICATIONS FOR REHABILITATIONOur dyadic behavioral sleep program can be tailored to various types of sleep problems among patients with Alzheimer's disease and their family caregivers, with the goal of improving daytime function by reducing sleep disturbances at night.Caregiver training and participation of both members of the dyad in sleep management may benefit the patients' sleep and other health outcomes, reduce caregiver stress and burden, and ultimately delay or prevent institutionalization of Alzheimer's disease patients.

Cognitive behavioral therapy for insomnia (CBTI) for comorbid insomnia and obstructive sleep apnea (OSA) has had mixed results. We integrated CBTI with a positive airway pressure (PAP) adherence program and tested effects on sleep and PAP use. 125 veterans (mean age 63.2, 96% men, 39% non-Hispanic white, 26% black/African American, 18% Hispanic/Latino) with comorbid insomnia and newly-diagnosed OSA (apnea-hypopnea index ≥ 15) were randomized to 5-weekly sessions integrating CBTI with a PAP adherence program provided by a "sleep coach" (with behavioral sleep medicine supervision), or 5-weekly sleep education control sessions. Participants and assessment staff were blinded to group assignment. Outcomes (baseline, 3 and 6 months) included Pittsburgh Sleep Quality Index (PSQI), 7-day sleep diary (sleep onset latency [SOL-D], wake after sleep onset [WASO-D], sleep efficiency [SE-D]), 7-day actigraphy (SE-A), and objective PAP use (hours/night and nights ≥ 4 h). Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), and Functional Outcomes of Sleep Questionnaire-10 (FOSQ-10) were also collected. Compared to controls, intervention participants showed greater improvement (baseline to 3 and 6 months, respectively) in PSQI (-3.2 and -1.7), SOL-D (-16.2 and -15.5 minutes), SE-D (10.5% and 8.5%), SE-A (4.4% and 2.6%) and more 90-day PAP use (1.3 and 0.9 more hours/night, 17.4 and 11.3 more nights PAP ≥ 4 h). 90-day PAP use at 3 months was 3.2 and 1.9 h/night in intervention versus controls. Intervention participants also had greater improvements in ISI, ESS, and FOSQ-10 (all p < 0.05). An intervention integrating CBTI with a PAP adherence program delivered by a supervised sleep coach improved sleep and PAP use in adults with comorbid insomnia and OSA.

Objective/Background: Sleep problems are common in women and caregiving for an adult is a common role among women. However, the effects of caregiving on sleep and related daytime impairment are poorly understood among women veterans. This study compared stress-related sleep disturbances, insomnia symptoms, and sleep-related daytime impairment between women veterans who were caregivers and those who did not have a caregiving role. Participants: Of 12,225 women veterans who received care in one Veterans Administration Healthcare System, 1,457 completed data on a postal survey (mean age = 51.7 ± 15.9 years). Two hundred forty three (17%) respondents (mean age 53.8 ± 12.7 years) were caregivers for an adult, predominantly for a parent, providing transportation. Methods: The survey included items that addressed insomnia symptoms, total sleep time, sleep-related daytime impairments, caregiving characteristics, self-rated health, pain, stress, body mass index, and demographic information. Results: In adjusted analyses, caregiver status did not directly predict sleep complaints alone. However, in multiple regression analyses, being a caregiver (odds ratio 1.7, p = .001) significantly predicted stress-related sleep disturbance, even after adjusting for age, pain, self-rated health, and other characteristics. Furthermore, being a caregiver (β = 3.9, p = .031) significantly predicted more symptoms of sleep-related daytime impairment after adjusting for age, pain, self-rated health, and other factors. Conclusions: Compared to noncaregivers, women veterans who were caregivers for an adult were more likely to report stress causing poor sleep, and more daytime impairment due to poor sleep. These findings suggest the need to target stress and other factors when addressing sleep disturbance among women veterans who are caregivers.

Study objectivesThe goals of this study were to estimate rates of undiagnosed, diagnosed, and treated sleep apnea in women veterans and to identify factors associated with diagnosis and treatment of sleep apnea in this population.MethodsA large nationwide postal survey was sent to a random sample of 4,000 women veterans who had received health care at a Veterans Health Administration (VA) facility in the previous 6 months. A total of 1,498 surveys were completed. Survey items used for the current analyses included: demographics; sleep apnea risk, diagnostic status, and treatment; symptoms of other sleep disorders (eg, insomnia); mental health symptoms; and comorbidities.ResultsAmong responders, 13% of women reported a prior sleep apnea diagnosis. Among women who reported a diagnosis of sleep apnea, 65% reported using positive airway pressure therapy. A sleep apnea diagnosis was associated with older age, higher BMI, non-Hispanic African American/Black racial/ethnic identity, being unemployed, other sleep disorder symptoms (eg, insomnia), depression and post-traumatic stress disorder symptoms, and multimorbidity. Among women without a sleep apnea diagnosis, 43% scored as "high risk" on the STOP (snoring, tiredness, observed apneas, blood pressure) questionnaire. High risk scores were associated with older age, higher BMI, African American/Black identity, other sleep disorder symptoms (eg, insomnia), mental health symptoms, and multimorbidity. Only BMI differed between women using vs not using positive airway pressure therapy.ConclusionsWomen veterans with diagnosed sleep apnea were commonly treated with positive airway pressure therapy, which is standard first-line treatment; however, many undiagnosed women were at high risk. Efforts to increase screening, diagnosis, and treatment of sleep apnea in women with comorbid mental and physical health conditions are needed.

Study objectivesPerson-centered obstructive sleep apnea (OSA) care is a collaborative approach that is respectful of an individual's health priorities. Informed decision-making is essential to person-centered care, especially as patients age. In a feasibility study, we evaluated the effects of a new decision aid (Decide2Rest) on OSA treatment decision-making in older adults.MethodsPatients (aged ≥ 60 years) with newly diagnosed OSA were recruited from two health care systems and randomized either to Decide2Rest or to a control program. Postintervention outcomes included 1) Decisional Conflict Scale (0-100, where 0 = low and 100 = high conflict), which measures perceptions of uncertainty, whether decisions reflect what matters most to patients, and whether patients feel supported in decision-making; 2) Preparation for Decision-Making scale (0-100, where 0 = least and 100 most prepared); and 3) OSA knowledge (0-100, where 0 = poor and 100 = outstanding). Multivariable linear regression models examined relationships between Decide2Rest and outcomes (Decisional Conflict Scale, Preparation for Decision-Making, OSA knowledge).ResultsSeventy-three patients were randomized to Decide2Rest (n = 36; mean age, 69 years; 72% male) vs control (n = 37; mean age, 69 years; 70% male). Results from the regressions, controlling for study site, indicate that the Decide2Rest program resulted in less decisional conflict (20.5 vs 32.7 on the Decisional Conflict Scale; P = .014), more preparedness for decision-making (87.8 vs 66.2 on the Preparation for Decision-Making scale; P < .001), and greater OSA knowledge (75.1 vs 65.3 OSA knowledge score; P = .04) scores than in the control group.ConclusionsThe Decide2Rest program promotes person-centered OSA decision-making for older patients with newly diagnosed OSA. Future studies are needed to optimize implementation of the program.Clinical trial registrationRegistry: ClinicalTrials.gov, Name: Improving Older Adults' Decision-Making for OSAT (eDecide2Rest); URL: https://clinicaltrials.gov/ct2/show/NCT03138993; Identifier: NCT03138993.

Subjective and objective estimates of sleep are often discordant among individuals with insomnia who typically under-report sleep time and over-report wake time at night. This study examined the impact and durability of cognitive-behavioural therapy for insomnia on improving the accuracy of sleep and wake perceptions in older adults, and tested whether changes in sleep quality were related to changes in the accuracy of sleep/wake perceptions. One-hundred and fifty-nine older veterans (97% male, mean age 72.2 years) who met diagnostic criteria for insomnia disorder were randomized to: (1) cognitive-behavioural therapy for insomnia (n = 106); or (2) attention control (n = 53). Assessments were conducted at baseline, post-treatment, 6-months and 12-months follow-up. Sleep measures included objective (via wrist actigraphy) and subjective (via self-report diary) total sleep time and total wake time, along with Pittsburgh Sleep Quality Index score. Discrepancy was computed as the difference between objective and subjective estimates of wake and sleep. Minutes of discrepancy were compared between groups across time, as were the relationships between Pittsburgh Sleep Quality Index scores and subsequent changes in discrepancy. Compared with controls, participants randomized to cognitive-behavioural therapy for insomnia became more accurate (i.e. minutes discrepancy was reduced) in their perceptions of sleep/wake at post-treatment, 6-months and 12-months follow-up (p

Study objectivesTo estimate the prevalence of insomnia disorder among older veterans and to study relationships among age and self-rated health, with insomnia disorder, self-reported sleep duration and sleep efficiency.MethodsA cross-sectional postal survey of community-dwelling older veterans (older than 60 years) seen at one VA Healthcare System in the prior 18 months was performed, which was constructed to align with the general diagnostic criteria for insomnia disorder (International Classification of Sleep Disorders, Second Edition [ICSD-2]). The survey also queried self-reported sleep duration, bedtime, and wake time, which were used to calculate sleep efficiency. The survey also asked about race/ethnicity and self-rated health (using the general health item from the Short Form-36).ResultsA completed survey was returned by 4,717 individuals (51.9% response rate; mean age 74.1 years). Of those, 2,249 (47.7%) met ICSD-2 diagnostic criteria for insomnia disorder. In logistic regression analyses, insomnia disorder was more likely among younger age categories (odds ratios [OR] 1.4-2.5) and in those with worse self-rated health (OR 2.1-14.4). Both total nocturnal sleep time and time in bed increased with older age (all P < .001), whereas sleep efficiency did not differ. Worse self-rated health was associated with shorter total nocturnal sleep time, more time in bed, and lower (worse) sleep efficiency.ConclusionsResults of the postal survey suggest that almost half of community-dwelling older veterans have insomnia disorder, which was more common in young-old and among those with worse self-rated health. Additional work is needed to address the high burden of insomnia among older adults, including those with poor health.

Objective/backgroundTo identify caregiving-related sleep problems and their relationship to mental health and daytime function in female Veterans.ParticipantsFemale Veterans (N = 1,477) from cross-sectional, nationwide, postal survey data.MethodsThe survey respondent characteristics included demographics, comorbidity, physical activity, health, use of sleep medications, and history of sleep apnea. They self-identified caregiving- related sleep problems (i.e., those who had trouble sleeping because of caring for a sick adult, an infant/child, or other respondents). Patient Health Questionnaire (PHQ-4) was used to assess mental health, and daytime function was measured using 11 items of International Classification of Sleep Disorders-2 (ICSD-2).ResultsFemale Veterans with self-identified sleep problems due to caring for a sick adult (n = 59) experienced significantly more symptoms of depression and anxiety (p < 0.001) and impairment in daytime function (e.g., fatigue, daytime sleepiness, loss of concentration, p < 0.001) than those with self-identified sleep problems due to caring for an infant or child (n = 95) or all other respondents (n = 1,323) after controlling for the respondent characteristics.ConclusionsHealthcare providers should pay attention to assessing sleep characteristics of female Veterans with caregiving responsibilities, particularly those caregiving for a sick adult.

OBJECTIVES:This study compared subjective (questionnaire) and objective (actigraphy) sleep assessments, and examined agreement between these methods, in vulnerable older adults participating in a Veterans Administration Adult Day Health Care (ADHC) program. METHODS:59 ADHC participants (95% male, mean age = 78 years) completed sleep questionnaires and 72 continuous hours of wrist actigraphy. Linear regression was used to examine agreement between methods and explore discrepancies in subjective/objective measures. RESULTS:Disturbed sleep was common, yet there was no agreement between subjective and objective sleep assessment methods. Compared with objective measures, one-half of participants reported worse sleep efficiency (SE) on questionnaires while one-quarter over-estimated SE. Participants reporting worse pain had a greater discrepancy between subjective and objective SE. CONCLUSIONS:Vulnerable older adults demonstrated unique patterns of reporting sleep quality when comparing subjective and objective methods. Additional research is needed to better understand how vulnerable older adults evaluate sleep problems. CLINICAL IMPLICATIONS:Objective and subjective sleep measures may represent unique and equally important constructs in this population. Clinicians should consider utilizing both objective and subjective sleep measures to identify individuals who may benefit from behavioral sleep treatments, and future research is needed to develop and validate appropriate sleep assessments for vulnerable older adults.

ObjectivesThis pilot study explored caregivers' attitudes toward core elements of a behavioral sleep intervention for managing sleep problems of older veteran care recipients and the caregivers, as an initial step for developing a dyadic sleep intervention program.MethodsFive caregivers (all women; age range, 66-75 years) participated in a focus group discussion. Data were collected at one Veterans Affairs, adult day health care program.ResultsCaregivers' poor sleep was not necessarily explained by their caregiving responsibility. Caregivers felt that behavioral recommendations regarding sleep compression scheduling, increased indoor physical activity, and outdoor light exposure would be acceptable sleep interventions for themselves and the care recipients. Some challenges to the sleep recommendation were identified and they included limiting naptime of care recipients and change of their current sleep schedule.ConclusionsCaregivers are receptive to some key components of behavioral approaches to improving sleep. Tailored sleep recommendation strategy is needed to address potential challenges.Clinical implicationsIf available within clinical care settings or delivered at the patient's home, caregivers of older veterans are likely to engage in behavioral sleep intervention programs.

ObjectivesTo examine relationships between cognitive expectancies about sleep and hypnotics and use of medications commonly used for insomnia (hypnotics).MethodsWe analyzed baseline data from older veterans who met diagnostic criteria for insomnia and were enrolled in a trial comparing CBTI delivered by a supervised, sleep educator to an attention control condition (N = 159; 97% male, mean age 72 years). We classified individuals as hypnotic users (N = 23) vs. non-users (N = 135) based upon medication diaries. Associations between hypnotic status and Dysfunctional Beliefs and Attitudes about Sleep-16 (DBAS) total score (0-10, higher = worse) and two DBAS medication item scores (Item 1: "…better off taking a sleeping pill rather than having a poor night's sleep;" Item 2: "Medication… probably the only solution to sleeplessness"; 0-10, higher = worse) were examined in logistic regression models.ResultsHigher scores on the DBAS medication items (both odds ratios = 1.3; p-values < .001) were significantly associated with hypnotic use. DBAS-16 total score was not associated with hypnotic use.ConclusionCognitive expectancy (dysfunctional beliefs) about hypnotics was associated with hypnotic use in older adults with chronic insomnia disorder.Clinical implicationsStrategies that specifically target dysfunctional beliefs about hypnotics are needed and may impact hypnotic use in older adults.

We examined whether baseline self-reported physical activity is associated with the efficacy of cognitive behavioral therapy for insomnia (CBT-I) in older veterans. Community-dwelling veterans aged 60 years and older with insomnia received CBT-I in a randomized controlled trial. Participants who received active treatment were divided into low and high physical activity based on self-report. Sleep outcomes were measured by sleep diary, questionnaire and wrist actigraphy; collected at baseline, post-treatment, 6-month and 12-month follow-up. Mixed-effects models compared differences between physical activity groups in change in sleep outcome from baseline to each follow-up, and equivalence tests examined if physical activity groups were clinically equal. There were no significant differences in sleep outcomes between physical activity groups. Equivalence tests suggested possible equality in physical activity groups for five of seven sleep outcomes. Efficacy of CBT-I in older veterans was not associated with self-reported physical activity at baseline. Older adults with insomnia who report low levels of physical activity can benefit from CBT-I.

STUDY OBJECTIVES:To examine whether change in caregiving status and intensity among community-dwelling older women was associated with sleep characteristics at follow-up, and whether perceived stress modified these associations. METHODS:The sample included 800 women aged 65 years or older who completed baseline and second follow-up interviews in the Caregiver-Study of Osteoporotic Fractures (Caregiver-SOF). Respondents were categorized into four groups based on change in caregiving status and intensity between the two time points: continuous noncaregivers, ceased caregivers, low-intensity caregivers (continuous caregivers with low/decreased intensity), and high-intensity caregivers (continuous caregivers with high/increased intensity or new caregivers). Perceived Stress Scale scores at the second follow-up were dichotomized into high versus low stress. Sleep outcomes at SOF Visit 8 (which overlapped with Caregiver-SOF second follow-up) included the Pittsburgh Sleep Quality Index total score; and actigraphy-measured total sleep time, sleep efficiency, wake after sleep onset, and sleep latency. RESULTS:Multivariate-adjusted sleep characteristics did not differ significantly across caregiving groups. Among high-intensity caregivers, however, those with high stress levels had significantly longer wake after sleep onset (mean 82.3 minutes, 95% confidence interval = 70.9-93.7) than those with low stress levels (mean 65.4 minutes, 95% confidence interval = 55.2-75.7). No other sleep outcomes were modified by stress levels. Further, higher stress was significantly associated with worse Pittsburgh Sleep Quality Index scores, regardless of the caregiving group. CONCLUSIONS:Overall, sleep characteristics did not differ among noncaregivers, ceased caregivers, or those with high-/low-intensity caregiving among older women. However, subgroups of caregivers may be vulnerable to developing sleep problems, particularly those with high stress levels.

Study objectiveTo test the effectiveness of a 4-week behavioral Sleep Intervention Program (SIP: sleep compression, modified stimulus control, and sleep hygiene) compared to a 4-week information-only control (IC) among older adults attending a VA Adult Day Health Care (ADHC) program in a double-blind, randomized, clinical trial.MethodsForty-two individuals (mean age: 77 years, 93% male) enrolled in a VA ADHC program were randomized to receive SIP or IC. All completed in-person sleep and health assessments at baseline, post-treatment and 4-months follow-up that included 3 days/nights of wrist actigraphy, the Pittsburgh Sleep Quality Index (PSQI), and the Insomnia Severity Index (ISI). Mixed repeated measures analysis was used to compare sleep outcomes at post-treatment and 4-months follow-up, with baseline values as covariates.ResultsSIP participants (n = 21) showed significant improvement on actigraphy sleep efficiency (p = .007), number of nighttime awakenings (p = .016), and minutes awake at night (p = .001) at post-treatment, compared to IC participants (n = 21). Benefits were slightly attenuated but remained significant at 4-month follow-up (all p's < .05). There were no differences in total sleep time between groups. There was significant improvement on PSQI factor 3 (daily disturbances) at 4-month follow-up (p = .016), but no differences were observed between SIP and IC on other PSQI components or ISI scores at post-treatment or 4-month follow-up.ConclusionsA short behavioral sleep intervention may have important benefits in improving objectively measured sleep in older adults participating in ADHC. Future studies are needed to study implementation of this intervention into routine clinical care within ADHC.

Study objectivesTo examine the usability of positive airway pressure (PAP) devices and its association with PAP adherence among older adults with sleep-disordered breathing.MethodsWe mailed questionnaires to patients aged ≥65 years prescribed PAP therapy during the prior 36 months from two large healthcare systems. Survey participants completed the Usability of Sleep Apnea Equipment-Positive Airway Pressure (USE-PAP) questionnaire, which assessed the usability of their PAP device. Other questionnaire items included demographics and self-rated health. We also abstracted adherence data (mean nightly hours of PAP use available from one site) and interface type from the electronic health record.ResultsFive hundred sixty-four patients completed the survey (response rate = 33%). The mean USE-PAP score (0 = best to 100 = worst) was 20 (SD ± 20). Mean duration of PAP use (available in 189 respondents) was 5.2 hours per night (SD ± 2.0). In a nested regression model predicting nightly hours of PAP use, a 10-point (0.5 SD) increase in USE-PAP score corresponded to a 0.37 hour/night reduction in PAP use. The model including the USE-PAP score explained a significant proportion (R2 = 15%) of the variation in nightly hours of PAP use above and beyond demographics, self-reported health, and interface type (∆R2 = 12%).ConclusionsOur results demonstrate that PAP usability varies among older patients and is associated with PAP adherence, above and beyond other predictors of adherence. These results support measuring and improving PAP usability to further improve PAP adherence for older patients.

PurposeFemale veterans are at high risk for sleep problems, and there is a need to provide effective treatment for this population who experience insomnia. This study's primary goal was to compare the acceptability of medication versus nonmedication treatments for insomnia among female veterans. In addition, we examined the role of patient age, severity of sleep disturbance, and psychiatric symptoms on acceptability of each treatment approach and on the differences in acceptability between these approaches.MethodsA large nationwide postal survey was sent to a random sample of 4000 female veterans who had received health care at a Veterans Administration (VA) facility in the previous 6 months (May 29, 2012-November 28, 2012). A total of 1559 completed surveys were returned. Survey items used for the current analyses included: demographic characteristics, sleep quality, psychiatric symptoms, military service experience, and acceptability of medication and nonmedication treatments for insomnia. For analysis, only ratings of "very acceptable" were used to indicate an interest in the treatment approach (vs ratings of "not at all acceptable," "a little acceptable," "somewhat acceptable," and "no opinion/don׳t know").FindingsIn the final sample of 1538 women with complete data, 57.7% rated nonmedication treatment as very acceptable while only 33.5% rated medication treatment as very acceptable. This difference was statistically significant for the group as a whole and when examining subgroups of patients based on age, sleep quality, psychiatric symptoms, and military experience. The percentage of respondents rating medication treatment as very acceptable was higher for women who were younger, had more severe sleep disturbances, had more psychiatric symptoms, who were not combat exposed, and who had experienced military sexual trauma. By contrast, the percentage of respondents rating nonmedication treatment as very acceptable differed only by age (younger women were more likely to find nonmedication treatment acceptable) and difficulty falling asleep.ImplicationsFemale veterans are more likely to find nonmedication insomnia treatment acceptable compared with medication treatment. Thus, it is important to match these patients with effective behavioral interventions such as cognitive behavioral therapy for insomnia. Efforts to educate providers about these preferences and about the efficacy of cognitive behavioral therapy for insomnia may serve to connect female veterans who have insomnia to the treatment they prefer. These findings also suggest that older female veterans may be less likely to find either approach as acceptable as their younger counterparts.

Objectives: Insomnia may contribute to fewer value-consistent choices and less engagement in meaningful life activities. We sought to identify values commonly expressed by women veterans engaged in a trial testing psychological treatment of insomnia disorder. Methods: Seventy-four women veterans (mean age = 48.3 [±13] years), meeting DSM-5 diagnostic criteria for insomnia disorder received an acceptance-based behavioral treatment for insomnia. In the first session, participants responded to questions regarding personal values and the impact of insomnia on those values. Responses were categorized into values domains informed by the Bull's Eye Values survey (level 1 categories) and the Valued Living Questionnaire (level 2 categories). Results: Raters reached 100% agreement after independent coding and adjudication. Level 1 value categories in frequency order were: relationships (n = 68), personal care/health (n = 51), work/education (n = 46), pets (n = 12), and leisure (n = 5). The most frequently reported level 2 value categories were: family (other than marriage/parenting; n = 50), parenting (n = 31), work (n = 31), physical health (n = 30), and spirituality (n = 19). The level 1 value categories impacted by insomnia in frequency order were: personal care/health (n = 65), relationships (n = 58), work/education (n = 46), pets (n = 12), and leisure (n = 5). Conclusions: Women veterans undergoing insomnia treatment highly value relationships and personal care/health, which should be considered patientcentered outcomes of insomnia treatments.

ObjectivesTo test a new cognitive behavioral therapy for insomnia (CBT-I) program designed for use by nonclinicians.DesignRandomized controlled trial.SettingDepartment of Veterans Affairs healthcare system.ParticipantsCommunity-dwelling veterans aged 60 and older who met diagnostic criteria for insomnia of 3 months duration or longer (N = 159).InterventionNonclinician "sleep coaches" delivered a five-session manual-based CBT-I program including stimulus control, sleep restriction, sleep hygiene, and cognitive therapy (individually or in small groups), with weekly telephone behavioral sleep medicine supervision. Controls received five sessions of general sleep education.MeasurementsPrimary outcomes, including self-reported (7-day sleep diary) sleep onset latency (SOL-D), wake after sleep onset (WASO-D), total wake time (TWT-D), and sleep efficiency (SE-D); Pittsburgh Sleep Quality Index (PSQI); and objective sleep efficiency (7-day wrist actigraphy, SE-A) were measured at baseline, at the posttreatment assessment, and at 6- and 12-month follow-up. Additional measures included the Insomnia Severity Index (ISI), depressive symptoms (Patient Health Questionnaire-9 (PHQ-9)), and quality of life (Medical Outcomes Study 12-item Short-form Survey version 2 (SF-12v2)).ResultsIntervention subjects had greater improvement than controls between the baseline and posttreatment assessments, the baseline and 6-month assessments, and the baseline and 12-month assessments in SOL-D (-23.4, -15.8, and -17.3 minutes, respectively), TWT-D (-68.4, -37.0, and -30.9 minutes, respectively), SE-D (10.5%, 6.7%, and 5.4%, respectively), PSQI (-3.4, -2.4, and -2.1 in total score, respectively), and ISI (-4.5, -3.9, and -2.8 in total score, respectively) (all P < .05). There were no significant differences in SE-A, PHQ-9, or SF-12v2.ConclusionManual-based CBT-I delivered by nonclinician sleep coaches improves sleep in older adults with chronic insomnia.

ObjectivesTo investigate the association between pain and functional independence in older adults during and after admission to rehabilitation after an acute illness or injury.DesignProspective, observational cohort study.SettingOne community and one Veterans Affairs rehabilitation center.ParticipantsIndividuals aged 65 and older admitted for rehabilitation after an acute illness or injury (postacute rehabilitation) (N = 245; mean age 80.6, 72% male)).MeasurementsPain was assessed using the Geriatric Pain Measure (GPM, score 0-100). Functional independence was measured using the motor component of the Functional Independence Measure (mFIM, score 13-91). Both scores were obtained at admission; discharge; and 3-, 6-, and 9-month follow-up. In bivariate analyses, discharge GPM and persistent pain (lasting >3 months) were evaluated as predictors of mFIM score at 9 months. Applying a multilevel modeling (MLM) approach, individual deviations in GPM scores were used to predict variations in mFIM.ResultsAt admission, 210 participants (87.9%) reported pain (16.3% mild (GPM70)); 21.3% reported persistent pain after discharge. The bivariate analyses did not find statistically significant associations between discharge GPM or persistent pain and mFIM score at 9 months, but in the MLM analysis, deviations in GPM were significant predictors of deviations in mFIM score, suggesting that, when individuals experienced above-average levels of pain (GPM > their personal mean GPM), they also experienced worse functional independence (mFIM < their personal mean mFIM).ConclusionTwenty-one percent of older adults undergoing postacute rehabilitation reported persistent pain after discharge from rehabilitation. The bivariate analysis did not find association between pain and functional independence, but MLM analysis showed that, when participants experienced more pain than their average, they had less functional independence.

OBJECTIVES: To examine whether sleep disturbance is associated with poor physical function in older veterans in an adult day healthcare (ADHC) program. DESIGN: Cross-sectional. SETTING: One ADHC program in a Veterans Affairs Ambulatory Care Center. PARTICIPANTS: Older veterans (N = 50) enrolled in a randomized controlled trial of a sleep intervention program who had complete baseline data. MEASUREMENTS: Information on participant characteristics (e.g., age, depression, relationship to caregiver, pain, comorbidity) was collected using appropriate questionnaires. Physical function was measured using activity of daily living (ADL) and instrumental ADL (IADL) total scores from the Older Americans Resources and Services Multidimensional Functional Assessment Questionnaire. Sleep was assessed subjectively (Pittsburgh Sleep Quality Index, Insomnia Severity Index) and objectively (wrist actigraphy). RESULTS: Participants required substantial assistance with ADLs and IADLs. A regression model showed that participant characteristics (marital status, use of sleep medication, comorbidity, posttraumatic stress disorder) and living arrangement (living with a spouse or others) were significantly associated with poor physical function. Poorer objective sleep (total sleep time, total numbers of awakenings, total wake time) was significantly associated with poor physical function, accounting for a significant proportion of the variance other than participant characteristics. CONCLUSION: Objective measures of nighttime sleep disturbance were associated with poor physical function in older veterans in an ADHC program. Further research is needed to determine whether interventions to improve sleep will delay functional decline in this vulnerable population.

Study objectiveTo investigate the associations between sleep stage distributions and subsequent decline in cognitive function in older men over time.DesignA population-based prospective substudy of the Osteoporotic Fractures in Men Study.SettingsSix sites in the United States.ParticipantsCommunity-dwelling men aged 67 y or older (n = 2,601), who were free of probable dementia at sleep visit. Follow-up averaged 3.4 y.Measurement and resultsSleep stages were identified by in-home polysomnography at the initial sleep visit (2003-2005). Cognitive outcomes were assessed with the Trail Making Test Part B and Modified Mini-Mental State Examination (3MS) at sleep visit and two follow-up visits. After adjusting for multiple confounders compared with men in the lowest quartile of percent of sleep time spent in Stage N1, those in the highest quartile had a twofold increase in cognitive decline for both cognitive tests (adjusted annualized percent change/y: Trail Making Test Part B Q1 = 1.06, Q4 = 2.45, P = 0.01; 3MS Q1 = -0.27, Q4 = -0.48, P = 0.03). In addition, compared with men in the highest quartile, men in the lowest quartile of percent of sleep time in Stage R revealed more cognitive decline on the 3MS (adjusted annualized percent change/y: Q1 = -0.49, Q4 = -0.22, P = 0.003). These findings were consistent even after further adjustment of total sleep time and sleep disordered breathing. No significant relationships between other sleep stages (N2, N3) and cognitive change were found.ConclusionIncreased time in Stage N1 and less time in Stage R are associated with worsening cognitive performance in older men over time.

ObjectivesTo determine whether sleep-disordered breathing (SDB), a group of disorders common in older adults characterized by breathing pauses during sleep often accompanied by hypoxemia, is associated with cognitive decline.DesignPopulation-based longitudinal study.SettingSix centers in the United States.ParticipantsCommunity-dwelling older men (N=2,636; aged 76.0±5.3) without probable mild cognitive impairment or dementia followed for 3.4±0.5 years.MeasurementsSDB was measured using in-home polysomnography: nocturnal hypoxemia (≥1% of sleep time with oxygen saturation (SaO2)

Examination of predictors of late-life cognitive functioning is particularly salient in at-risk older adults, such as those who have been recently hospitalized. Sleep and inflammation are independently related to late-life cognitive functioning. The potential role of sleep as a moderator of the relationship between inflammation and global cognitive functioning has not been adequately addressed. We examined the relationship between self-reported sleep duration, inflammatory markers, and general cognitive functioning in hospitalized older men. Older men (n = 135; Mean age = 72.9 ± 9.7 years) were recruited from inpatient rehabilitation units at a VA Medical Center to participate in a cross-sectional study of sleep. Participants completed the Mini-Mental State Examination and Pittsburgh Sleep Quality Index, and underwent an 8 a.m. blood draw to measure inflammatory markers [i.e., C-reactive protein (CRP), tumor necrosis factor alpha (TNFα), soluble intercellular adhesion molecule-1 (sICAM-1), and interleukin-6 (IL-6)]. Hierarchical regression analyses (controlling for age, education, race, depression, pain, health comorbidity, and BMI) revealed that higher levels of CRP and sICAM are associated with higher global cognitive functioning in older men with sleep duration ≥6 h (β = -0.19, β = -0.18, p's < 0.05, respectively), but not in those with short sleep durations (p's > 0.05). In elderly hospitalized men, sleep duration moderates the association between inflammation and cognitive functioning. These findings have implications for the clinical care of older men within medical settings.

Study objectivesTo examine associations of objectively and subjectively measured sleep with subsequent cognitive decline.DesignA population-based longitudinal study.SettingSix centers in the United States.ParticipantsParticipants were 2,822 cognitively intact community-dwelling older men (mean age 76.0 ± 5.3 y) followed over 3.4 ± 0.5 y.InterventionsNone.Measurements and resultsOBJECTIVELY MEASURED SLEEP PREDICTORS FROM WRIST ACTIGRAPHY: total sleep time (TST), sleep efficiency (SE), wake after sleep onset (WASO), number of long wake episodes (LWEP). Self-reported sleep predictors: sleep quality (Pittsburgh Sleep Quality Index [PSQI]), daytime sleepiness (Epworth Sleepiness Scale [ESS]), TST. Clinically significant cognitive decline: five-point decline on the Modified Mini-Mental State examination (3MS), change score for the Trails B test time in the worse decile. Associations of sleep predictors and cognitive decline were examined with logistic regression and linear mixed models. After multivariable adjustment, higher levels of WASO and LWEP and lower SE were associated with an 1.4 to 1.5-fold increase in odds of clinically significant decline (odds ratio 95% confidence interval) Trails B test: SE < 70% versus SE ≥ 70%: 1.53 (1.07, 2.18); WASO ≥ 90 min versus WASO < 90 min: 1.47 (1.09, 1.98); eight or more LWEP versus fewer than eight: 1.38 (1.02, 1.86). 3MS: eight or more LWEP versus fewer than eight: 1.36 (1.09, 1.71), with modest relationships to linear change in cognition over time. PSQI was related to decline in Trails B performance (3 sec/y per standard deviation increase).ConclusionsAmong older community-dwelling men, reduced sleep efficiency, greater nighttime wakefulness, greater number of long wake episodes, and poor self-reported sleep quality were associated with subsequent cognitive decline.
