Factors associated with sleep in family caregivers of individuals with dementia

Caregiver burden and psychological status and their associations with sleep quality among family caregivers living with older people with dementia: A mixed method study

This mixed method study evaluated caregiver burden and psychological status and their associations with objective sleep quality among seven pairs of older people with dementia (PWD) and their family caregivers (FCs). The Barthel index, the Zarit Burden Interview (ZBI), and conversations data with a virtual agent were used to assess caregiver burden, the Profile of Mood States (POMS) to assess the FCs' psychological status, and Nemuri SCAN to measure sleep quality. As a result, sleep duration was negatively correlated with POMS Confusion-Bewilderment and Vigor-Activity (VA), sleep efficiency was positively correlated with ZBI and negatively correlated with POMS-VA, sleep latency was positively correlated with POMS Tension-Anxiety, and wake after sleep onset was negatively correlated with ZBI and positively correlated with POMS Depression-Dejection and VA. The lack of sleep or night care and good mood among PWD affected the FCs' sleep quality. These findings could contribute to reduce the FC's caregiver burden.

Integrating lived experience to develop a tailored sleep intervention for people living with dementia and carepartners

OBJECTIVES

Sleep disturbances are highly prevalent and have adverse health consequences for both people living with dementia and their carepartners. Despite this, they are under-addressed caregiving settings. This study aimed to explore these sleep disturbances and co-design a multimodal sleep intervention for people living with dementia and their carepartners.

METHODS

We conducted two focus groups and five semi-structured interviews (n = 4 people living with dementia, n = 6 carepartners). Active involvement of community advisors was sought throughout the design, development, and facilitation phases. Reflexive thematic analysis was used to explore sleep-related experiences and receive feedback to shape intervention development.

FINDINGS

People living with dementia reported disruptions to sleep and circadian rhythms, including sleep disturbances and confusion between day and night. Multiple sleep challenges were encountered by carepartners including insomnia, hypervigilance, and daytime impairment. The proposed sleep intervention was received positively, with significant insights emphasising the need for a multimodal toolkit approach, adaptation of the intervention across different dementia stages, and a focus on tailoring the program to carepartners.

CONCLUSION

Sleep interventions for caregivers and care-recipients should target both sleep and daytime functioning to ensure holistic support. Participants were receptive towards time-friendly, online, multimodal sleep interventions that combine cognitive behaviour therapies, light therapy, mindfulness, and exercise elements.

Walking Interventions and Sleep Quality of Persons Living With Dementia and Their Family Caregivers: Effects of Different Walking Companions

PURPOSE

To examine the effect of walking interventions on sleep quality of persons with dementia (PWD) and their caregivers (dyads), and how different companions affect results.

METHOD

Forty-five dyads were divided into three groups: a control group and two experimental groups (one with a care attendant, one with a family caregiver). The two experimental groups engaged in 120 minutes of walking per week for 24 weeks.

RESULTS

A significant improvement in sleep quality was observed among PWD in the family caregiver group (Wald χ2 = 4.55, p = 0.033), whereas there was no improvement in the care attendant group. A slight improvement in sleep quality of family caregivers was also found.

CONCLUSION

Findings suggest the importance of creating individualized walking activity plans for dyads, incorporating trust and rapport-building strategies to improve sleep quality. [Journal of Gerontological Nursing, 50(8), 46-56.].

Poor sleep and inflammatory gene expression among care partners of persons living with dementia: a pilot trial of a behavioral sleep intervention

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.

An integrated model of psychosocial correlates of insomnia severity in family caregivers of people with dementia

OBJECTIVES

Research has shown the relevance of stress and coping factors in explaining caregivers' insomnia symptoms. However, few attempts have been made to empirically test an integrative model for insomnia severity in family caregivers of people with dementia. The aim of this study was to test such a model, in which insomnia severity is proposed to be influenced by predisposing factors, precipitated by stressors, and perpetuated by behaviors to cope with these stressors.

METHODS

311 family caregivers of people with dementia were assessed for variables categorized as predisposing (e.g. female gender), precipitating (e.g. care-recipient's behavioral and psychological symptoms of dementia [BPSD]), and perpetuating factors (e.g. sleep aids). A theoretical model was developed and then statistically tested using structural equation modelling, analyzing the direct and indirect effects of the assessed variables on caregivers' insomnia severity.

RESULTS

Distress, sleep aids, and experiential avoidance showed a direct association with insomnia severity. Female gender, younger age, cognitive fusion, leisure activities, dysfunctional thoughts, frequency and distress caused by care-recipient's BPSD showed indirect associations with insomnia severity. The model explained 22% of the variance of caregivers' insomnia severity.

CONCLUSION

The results provide additional empirical support for the importance of predisposing, precipitating and perpetuating factors associated with caregivers' insomnia severity. The integrative model we propose may also be useful for developing interventions targeting insomnia symptoms in family dementia caregivers.

Sleep quality differences among caregivers for persons living with and without dementia

OBJECTIVES

This study examined the relationship between caring for a person with/without dementia and caregiver sleep quality, and analyzed the extent to which perceived benefits of caregiving and assessments of caregiver-recipient relationship quality explain the relationship between care recipient dementia status and caregiver sleep quality.

METHOD

Data were analyzed from caregivers for persons with no or probable dementia who participated in the 2017 National Study of Caregiving (NSOC) and National Health and Aging Trends Study. Caregiver sleep quality was measured using NSOC time diary interview. Perceptions of caregiving and relationship quality were assessed using 4-item surveys. We used multivariable logistic regressions to examine the association between care recipient dementia status and caregiver sleep quality controlling for covariates.

RESULTS

The sample consisted of 1,374 caregivers (mean age = 62.3, SD = 14, 68.3% women, 69.4% non-Hispanic White). In multivariable models adjusting for caregiver and care recipient characteristics, being a caregiver for someone with dementia was associated with 23% lower odds of reporting "excellent/very good" sleep quality (OR: 0.77, 95%CI: 0.61-0.98, p = 0.032). Greater perception of caregiving benefits was associated with 8% greater odds of "excellent/very good" sleep quality (AOR: 1.08, 95%CI: 1.02-1.15, p = 0.013), but did not explain the relationship between dementia and caregiver sleep quality. Positive ratings of relationship quality explained the relationship between care recipient dementia status and caregiver sleep quality (AOR: 0.82, 95%CI: 0.65-1.05, p = 0.12).

CONCLUSION

Improving assessments of relationship quality and amplifying perceptions of caregiving benefits may reduce disparities in sleep quality between caregivers of persons living with or without dementia.

Correlates of Sleep Disturbance Experienced by Informal Caregivers of Persons Living with Dementia: A Systematic Review

OBJECTIVES

This study aims to comprehensively review and update the literature concerning the correlates of sleep disturbance among caregivers of persons living with Alzheimer's disease and related dementias to identify gaps in the literature and antecedent targets for interventions.

METHODS

We searched PubMed, CINAHL, PsycINFO, and Embase using terms related to "sleep," "caregiver," and "dementia."

RESULTS

Thirty-six articles were included in this review. Based on the antecedents within the 3P model of insomnia, predisposing factors associated with caregiver sleep included caregiver demographics, and physiological factors like genotype and biomarkers. Precipitating factors related to caregiver sleep included caregiving status and responsibilities, and person living with dementia factors.

CONCLUSIONS

Sleep disturbance is a significant issue for caregivers of persons living with dementia. However, this review has identified multiple precipitating factors that are modifiable targets for interventions to improve or enhance caregiver sleep.

CLINICAL IMPLICATIONS

Numerous predisposing and precipitating factors contribute to caregivers of persons living with dementia being susceptible to sleep disturbance. Healthcare providers should ask patients about their caregiving status during annual visits. Healthcare providers should also evaluate caregivers' sleep patterns, and the predisposing and precipitating factors of sleep disturbance, with a focus on the modifiable factors, to enable timely intervention.

Characterization of sleep efficiency transitions in family caregivers

Family caregivers are at high risk of psychological distress and low sleep efficiency resulting from their caregiving responsibilities. Although psychological symptoms are associated with sleep efficiency, there is limited knowledge about the association of psychological distress with variations in sleep efficiency. We aimed to characterize the short- and long-term patterns of caregivers' sleep efficiency using Markov chain models and compare these patterns between groups with high and low psychological symptoms (i.e., depression, anxiety, and caregiving stress). Based on 7-day actigraphy data from 33 caregivers, we categorized sleep efficiency into three states, < 75% (S1), 75-84% (S2), and ≥ 85% (S3), and developed Markov chain models. Caregivers were likely to maintain a consistent sleep efficiency state from one night to the next without returning efficiently to a normal state. On average, it took 3.6-5.1 days to return to a night of normal sleep efficiency (S3) from lower states, and the long-term probability of achieving normal sleep was 42%. We observed lower probabilities of transitioning to or remaining in a normal sleep efficiency state (S3) in the high depression and anxiety groups compared to the low symptom groups. The differences in the time required to return to a normal state were inconsistent by symptom levels. The long-term probability of achieving normal sleep efficiency was significantly lower for caregivers with high depression and anxiety compared to the low symptom groups. Caregivers' sleep efficiency appears to remain relatively consistent over time and does not show rapid recovery. Caregivers with higher levels of depression and anxiety may be more vulnerable to sustained suboptimal sleep efficiency.

Multi-modal sleep intervention for community-dwelling people living with dementia and primary caregiver dyads with sleep disturbance: protocol of a single-arm feasibility trial

Background

Disturbed sleep is common among people living with dementia and their informal caregivers, and is associated with negative health outcomes. Dyadic, multi-modal interventions targeting caregiver and care-recipient sleep have been recommended yet remain limited. This protocol details the development of a single-arm feasibility trial of a multi-modal, therapist-led, six-week intervention targeting sleep disturbance in dyads of people living with dementia and their primary caregiver.

Methods

We aim to recruit 24 co-residing, community-dwelling dyads of people living with dementia and their primary informal caregiver (n = 48) with sleep concerns (Pittsburgh Sleep Quality Index ≥5 for caregivers, and caregiver-endorsed sleep concerns for the person living with dementia). People who live in residential care settings, are employed in night shift work, or are diagnosed with current, severe mental health conditions or narcolepsy, will be excluded. Participants will wear an actigraph and complete sleep diaries for two weeks prior, and during the last two weeks, of active intervention. The intervention is therapist-led and includes a mix of weekly small group video sessions and personalised, dyadic sessions (up to 90 min each) over six weeks. Sessions are supported by a 37-page workbook offering strategies and spaces for reflections/notes. Primary feasibility outcomes are caregiver: session attendance, attrition, and self-reported project satisfaction. Secondary outcomes include dyadic self-reported and objectively-assessed sleep, depression and anxiety symptoms, quality of life, and social support. Self-report outcomes will be assessed at pre- and post-intervention.

Discussion

If feasible, this intervention could be tested in a larger randomised controlled trial to investigate its efficacy, and, upon further testing, may potentially represent a non-pharmacological approach to reduce sleep disturbance among people living with dementia and their caregivers.

The Effect of Tele-Savvy on Sleep Quality and Insomnia in Caregivers of Persons Living with Dementia

Introduction

Sleep disturbance is prevalent in caregivers of persons living with dementia (PLwD). Tele-Savvy, a 7-week virtual psychoeducational intervention, enhances caregivers' competence and self-care, and reduces depression. While not explicitly designed to do so, Tele-Savvy can potentially improve caregivers' disturbed sleep. The present study aimed to examine the longitudinal effects of Tele-Savvy on caregivers' sleep quality and insomnia.

Methods

This was a secondary data analysis of a 3-arm randomized control trial [Tele-Savvy (active treatment), Healthy Living (attention control), and usual care (waitlist control)]. Multilevel mixed modeling with intent-to-treat principles tested for group, time, and group-by-time effects. Effect sizes were estimated for all changes from baseline to the initial 6-month post-intervention point. Following completion of the 6-month post-randomization delay, we examined combined outcomes for Tele-Savvy.

Results

Participants (n=137; mean age 64.7 years) were predominantly female (68.6%) and White (68.6%). We found no initial group-by-time effects for the Pittsburgh Sleep Quality Index (PSQI) and the Insomnia Severity Index (ISI). For the combined Tele-Savvy group, there was a statistically significant improvement in ISI scores across time (p=0.050). The combined Tele-Savvy effect size for PSQI was d=0.126 and ISI was d=0.310.

Discussion

Tele-Savvy resulted in a significant long-term reduction in insomnia symptoms in this sample of caregivers of PLwD and demonstrated a positive trend for improvement in their sleep quality. Since sleep disturbance is so prevalent among caregivers of PLwD, the inclusion of sleep health education into psychoeducation caregiver interventions may yield even better outcomes for caregivers.

Predictors of Sleep Quality in Spouse Caregivers of Community-Dwelling People With Dementia Using Propensity Score Matching Analysis

BACKGROUND

Many family caregivers of people with dementia (PwDs) have sleep problems and poor sleep quality. Sleep may be negatively affected by caring for a family member with dementia, especially a spouse.

PURPOSE

This study was designed to assess sleep quality in spouse caregivers of PwDs and determine the impact of care provision on their sleep quality.

METHODS

A secondary analysis of 58,050 participants in the 2018 Korea Community Health Survey was conducted. To prevent selection bias, a propensity score matching analysis was performed. Multiple logistic regression analysis was conducted to investigate the predictors of sleep quality.

RESULTS

After obtaining a propensity score matching threshold of 3:1, the percentage of poor sleepers was 24.2% in the control group and 33.3% in the spouse-caregiver group, which indicates a significant difference (χ 2 = 11.79, p = .001). After adjusting for depressive symptoms in the multiple logistic analyses, no intergroup difference was found in terms of risk of poor sleep quality (odds ratio = 1.12, 95% CI [0.90, 1.61]).

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

The findings of this study support that spouse caregivers of PwDs have poorer sleep quality than their nonspouse peers and that management of depressive symptoms is important to improving the sleep quality of spouses providing care to PwDs. Nursing interventions such as light therapy and exposure to sunlight during daytime hours to both improve sleep quality and reduce depressive symptoms can improve sleep quality in this vulnerable caregiver group.

Remote evaluation of sleep to enhance understanding of early dementia due to Alzheimer's Disease (RESTED-AD): an observational cohort study protocol

BACKGROUND

Sleep and circadian rhythm disorders are well recognised in both AD (Alzheimer's Disease) dementia and MCI-AD (Mild Cognitive Impairment due to Alzheimer's Disease). Such abnormalities include insomnia, excessive daytime sleepiness, decreased sleep efficiency, increased sleep fragmentation and sundowning. Enhancing understanding of sleep abnormalities may unveil targets for intervention in sleep, a promising approach given hypotheses that sleep disorders may exacerbate AD pathological progression and represent a contributory factor toward impaired cognitive performance and worse quality of life. This may also permit early diagnosis of AD pathology, widely acknowledged as a pre-requisite for future disease-modifying therapies. This study aims to bridge the divide between in-laboratory polysomnographic studies which allow for rich characterisation of sleep but in an unnatural setting, and naturalistic studies typically approximating sleep through use of non-EEG wearable devices. It is also designed to record sleep patterns over a 2 month duration sufficient to capture both infradian rhythm and compensatory responses following suboptimal sleep. Finally, it harnesses an extensively phenotyped population including with AD blood biomarkers. Its principal aims are to improve characterisation of sleep and biological rhythms in individuals with AD, particularly focusing on micro-architectural measures of sleep, compensatory responses to suboptimal sleep and the relationship between sleep parameters, biological rhythms and cognitive performance.

METHODS/DESIGN

This observational cohort study has two arms (AD-MCI / mild AD dementia and aged-matched healthy adults). Each participant undergoes a baseline visit for collection of demographic, physiological and neuropsychological information utilising validated questionnaires. The main study period involves 7 nights of home-based multi-channel EEG sleep recording nested within an 8-week study period involving continuous wrist-worn actigraphy, sleep diaries and regular brief cognitive tests. Measurement of sleep parameters will be at home thereby obtaining a real-world, naturalistic dataset. Cognitive testing will be repeated at 6 months to stratify participants by longitudinal disease progression.

DISCUSSION

This study will generate new insights particularly in micro-architectural measures of sleep, circadian patterns and compensatory sleep responses in a population with and without AD neurodegenerative change. It aims to enhance standards of remotely based sleep research through use of a well-phenotyped population and advanced sleep measurement technology.

Depressive symptoms and sleep in aged caregivers in a context of high social vulnerability

OBJECTIVE

To evaluate the relationship between depressive symptoms and sleep quality in aged caregivers of elderly people, in a context of high social vulnerability.

METHODS

A Cross-sectional study conducted between July 2019 and March 2020 with 65 aged caregivers of elderly people that were treated in five Family Heath Units from São Carlos, São Paulo. Instruments to characterize the caregivers and to evaluate the depressive symptoms and sleep quality were used in data collection. The Kruskal Wallis and Spearman Correlation tests were adopted.

RESULTS

73.9% of the caregivers presented poor sleep quality and 69.2% did not have depressive symptoms. In the caregivers with severe depressive symptoms, the mean sleep quality score was 11.4; in those with mild depressive symptoms, it was 9.0; and in those without depressive symptoms, it was 6.4. There was a direct and moderate correlation between sleep quality and depressive symptoms.

CONCLUSION

There is a relationship between depressive symptoms and sleep quality in aged caregivers.

Sleep Quality and Depressive Symptoms in Caregivers of Persons with Dementia: A Systematic Review

A majority of the care provided to persons with dementia is provided by unpaid or informal caregivers (friends or family members), and most caregivers have limited care-related training, which increases their risks of developing depressive symptoms. Also, persons with dementia may experience sleep-related stressors at night. Disruptive behavior and sleep of the care recipients may produce stress in the caregivers, which has been considered a precipitating factor for sleep issues among caregivers. This systematic review aims to examine the available literature to investigate depressive symptoms and sleep quality among informal caregivers of persons with dementia. Using PRISMA guidelines, only eight articles fulfilled the inclusion criteria. Sleep quality and depressive symptoms should be investigated because they may influence caregivers' health and their involvement in caregiving.

"I need to be alert at night to provide care": Factors associated with problematic sleep among young Australian caregivers

OBJECTIVES

There is increased recognition that young people (<25 years) may occupy a carer role for family or others with health conditions or disability. This is often in addition to study and social activities. This means competing demands on time, and insufficient sleep. Our aim was to determine the contribution of caring duties to problematic sleep in young carers.

METHODS

A survey of Australian carers was conducted, including questions on demographics, characteristics of the carer and care recipient, and sleep quality and quantity. Participants were eligible if they reported sleep time <7 hr or dissatisfaction with their sleep, and were aged 15-24 years.

RESULTS

A total of 110 participants (71.8%_female = 79, 15-17 years = 62, 18-24 years = 48) were included in analysis; 55.5% (n= 61) reporting dissatisfaction with their sleep and 62.7% (n= 69) reporting typically less than 7 hr sleep per night. Sleep duration was significantly shorter for those who reported 1-2 or ≥3 awakenings to provide care, compared with no awakenings (p_< .05). Sleep quality, as described by scores on the Pittsburgh Sleep Quality Index (PSQI) was also significantly worse for those who were frequently awoken by their care recipient (p < .05). Worrying about the care recipient, being woken by the care recipient, and listening out for the care recipient were the most frequently identified factors impacting on sleep.

CONCLUSION

Young carers experience reduced sleep duration and poor sleep quality. Strategies to alleviate the burden of care work on young carer's sleep would benefit the health and safety of this group.

The associations between working conditions and subjective sleep quality among female migrant care workers

Background

Subjective sleep quality may reflect the mental well-being of migrant care workers; however, the related occupational factors remain unclear. This study examines the association between the characteristics of care labor and the subjective sleep quality of female migrants.

Methods

In this cross-sectional study, Southeast Asian migrant care workers in Taiwan were recruited using convenience sampling. Data on working conditions, including workplace setting, wage, working hours, psychiatric symptoms of care recipients, and sleep quality measured using the Pittsburgh Sleep Quality Index (PSQI), were collected through computer-assisted personal interviews. Multiple linear regression analyses were performed to determine the independent relationship between working conditions and the PSQI global score.

Results

There were 220 institution-(47.7%) and home-based (52.3%) care workers, and 47.7% had a PSQI score higher than 5. After controlling for covariates, the lowest tertile of wages and daily working hours (> 8 h) were independently correlated with poor sleep quality. Moreover, in the stepwise regression model, wage and working hours remained the most explainable correlates of poor sleep quality.

Conclusion

This study lent support to the notion that low wages and long working hours are significant occupational factors that negatively impact the subjective sleep quality of female Southeast Asian migrant care workers in Taiwan.

Correlation between burden and sleep quality in informal caregivers of infants with orofacial cleft

Abstract Objective: To evaluate the correlation between burden and sleep quality in caregivers of infants with cleft lip and/or palate. Methods: This descriptive cross-sectional study was carried out in a Brazilian tertiary public hospital between March and September 2020. The sample included the main informal, literate caregivers of infants with cleft lip and/or palate, aged 18 years or older. The instruments used were the Burden Interview Scale and the Pittsburgh Sleep Quality Index. Data were collected during the infants’ hospitalization. Statistical analysis adopted Pearson and Spearman correlations, with a 5% significance level. Results: A total of 31 informal caregivers participated in the study, most of them mothers (n=28; 90%), with a mean age of 30 years (standard deviation – SD=7.5), low socioeconomic status (n=20; 64%), who completed high school (n=19; 61%), were married (58%), had two children (n=15; 48%), and no employment relationship (n=18; 58%). A moderate correlation was found between sleep quality and burden (r=0.39; p=0.032) and between burden and subjective sleep quality (r=0.39; p=0.029), sleep latency (r=0.43; p=0.017), and daytime dysfunction (r=0.49; p<0.001). Conclusions: The study showed that the higher the burden, the lower the sleep quality. The findings indicate the need to plan and implement interventions to minimize the burden experienced by these informal caregivers in order to improve their sleep quality.

Prevalence of sleep disturbances in people with dementia living in the community: A systematic review and meta-analysis

This study aimed to systematically review and meta-analyse the prevalence of sleep disturbances in people with dementia and examine demographic predictors and whether overall prevalence has changed over time. We searched Embase, MEDLINE and PsycINFO for studies reporting the prevalence of sleep disturbances in people with dementia living at home. We meta-analysed the data and calculated the pooled prevalence of sleep disturbances in people with dementia overall and in dementia subtypes. We used meta-regressions to investigate the effects of study characteristics, publication dates and participant demographics. Eleven studies fulfilled the inclusion criteria. The pooled prevalence of any symptoms of sleep disturbance was 26 % (95 % confidence intervals, CI: 23-30 %; n = 2719) and of clinically significant sleep disturbance 19 % (13-25 %; n = 2753). The pooled prevalence of sleep disturbance symptoms was significantly lower among people with Alzheimer's disease (24 %; 16-33 %, n = 310) than Lewy body dementia (49 %; 37-61 %, n = 65). Meta-regression analysis did not find that publication year, participant's age, sex and study quality predicted prevalence. Sleep disturbances are common among people with dementia living in the community, especially in Lewy body dementia. There was no change in prevalence according to publication dates, suggesting treatment has not improved over time.

Sleep Disturbance, Psychological Distress and Perceived Burden in Female Family Caregivers of Dependent Patients with Dementia: A Case-Control Study

This case-control study analyzed the sleep disturbance, psychological distress and perceived burden in female family caregivers of dependent people with dementia (n = 74) compared with female family caregivers of dependent people without dementia (n = 74) and with age-matched non-caregiver control females (n = 74). Participants completed the Pittsburgh Sleep Quality Index (PSQI), the 12-item General Health Questionnaire (GHQ-12), the Caregiver Burden Inventory (CBI) and an ad hoc questionnaire to collect sociodemographic data. There were significant differences between the groups in PSQI total (F = 24.93; p < 0.001), psychological distress (F = 26.71; p < 0.001) and in all sleep domains assessed: subjective sleep quality (F = 16.19; p < 0.001), sleep latency (F = 9.5; p< 0.001), sleep duration (F = 18.57; p < 0.001), habitual sleep efficiency (F = 19.77; p < 0.001), sleep disturbances (F = 9.22; p < 0.001), use of sleep medications (F = 4.24; p< 0.01) and daytime dysfunction (F = 5.57; p < 0.01). In all measures, the female family caregivers of dependent people with dementia showed the significantly higher mean scores. Regarding the two groups of female caregivers, statistically significant differences were found in daily hours of care (t = −2.45; p < 0.05) and perceived burden (t = −3.65; p < 0.001), as well as in the following dimensions of caregiver burden: time-dependence burden (t = −5.09; p < 0.001), developmental burden (t = −2.42; p < 0.05) and physical burden (t = −2.89; p < 0.01). These findings suggest that female family caregivers of dependent patients with dementia should be subject to psychopathological screening and preventive cognitive-behavioral interventions in clinical practice in primary health care.

Daily sleep, well-being, and adult day services use among dementia care dyads

OBJECTIVES

The study aimed to describe daily sleep characteristics for dementia care dyads in the context of adult day services (ADS) use and examine the associations with sleep quality and daytime functioning (fatigue, affect, and behavior problems).

METHODS

Caregivers (CG; N = 173) reported daily bedtime, wake time, and sleep quality for themselves and the persons living with dementia (PLWD) across 8 consecutive days (N = 1359), where PLWD attended ADS at least 2 days of the week. On each day, caregivers also reported their own fatigue and affect and PLWD's daytime behavior problems and nighttime sleep problems. Considering the context of ADS use, we compared mean differences in bedtime, wake time, and total time in bed on nights before versus after ADS use. We estimated multilevel models to examine daily sleep-well-being associations.

RESULTS

On nights before an upcoming ADS day, care dyads went to bed and woke up earlier, and spent less time in bed. Further, PLWD had better sleep quality the night before an upcoming ADS day. Using ADS during the day buffered the negative impact of PLWD's sleep problems in the previous night, reducing daytime negative affect for caregivers. For caregivers, using ADS yesterday attenuated the association between shorter than typical time in bed and daytime fatigue; it also attenuated the association between PLWD's nighttime sleep problems and lowered daytime positive affect.

CONCLUSIONS

Regular ADS use may promote earlier sleep timing and protect against the adverse impact of sleep disturbances on daytime functioning for dementia care dyads.

Sleep disturbance in caregivers of individuals with Parkinsonism: a systematic review and meta-analysis

OBJECTIVES

The global prevalence of Parkinsonism continues to rise given ageing populations. Individuals with Parkinsonism who have moderate or severe symptoms typically require a high level of care, including assistance with activities of daily living. This care is often provided across the 24-hour period by a family member or friend. It is likely that providing care significantly impacts the sleep duration and quality of the caregiver given overnight caring responsibilities, in addition to worry and stress associated with the caregiving role. The aim of this systematic review and meta-analysis was to investigate whether providing care to an individual with Parkinsonism was associated with disturbed caregiver sleep, and to identify associated factors that may contribute to disturbed sleep in this population.

SETTING

Five databases were electronically searched on 30 June 2021 including CINAHL, PubMed, PsycINFO, CENTRAL and EMBASE.

PARTICIPANTS

Eligibility criteria included a population of caregivers whose care recipient has a form of Parkinsonism.

PRIMARY AND SECONDARY OUTCOME MEASURES

To be included in this systematic review, outcome measures of caregiver sleep (eg, sleep duration, sleep quality) were required.

RESULTS

Eighteen studies (n=1998) were included. Findings indicated that caregivers of individuals with Parkinsonism typically experience poor sleep quality (mean (95% CI): 5.6 (4.8 to 6.4) points on the Pittsburgh Sleep Quality Index), increased sleep latency and poor sleep efficiency.

CONCLUSIONS

The degree of poor sleep quality was clinically significant. However, further investigation of sleep outcomes is required using sleep measurement tools tailored for this population (eg, measures that capture overnight sleep disruption by care recipient/s). Additionally, there is a need for appropriate individual and societal-level interventions to improve caregiver sleep.

Telephone-Based Behavioral Activation for Improving Sleep Quality in Family Caregivers of People With Dementia: A Pilot Randomized Controlled Trial

Sleep disturbances are common among family caregivers of people with dementia (PWD). Although behavioral activation (BA) shows the potential to improve sleep quality, to date, evidence for this treatment's feasibility and efficacy for family caregivers of PWD is limited. Therefore, this study pilot tested an evidence-based BA protocol for improving sleep quality in Chinese family caregivers of PWD. The BA intervention involved eight weekly individual telephone-based sessions designed to teach caregivers specific BA techniques. Sleep quality and depression were measured using the Chinese versions of the Pittsburgh Sleep Quality Index (PSQI) and Center for Epidemiologic Studies Depression (CES-D) Scale, respectively. This study also measured leisure activity, positive aspect of caregiving, caregiving burden, health status, and relationship satisfaction. All participants were asked to complete the assessments on paper at baseline and immediately after the intervention. After completing the pilot randomized controlled trial, semistructured interviews were conducted to explore participants' experiences participating in the BA intervention. A total of 71 family caregivers of PWD (35 in the intervention group and 36 in the control group) were recruited. The majority of participants were female (n = 53, 74.65%), and their mean age was 54.07 years (SD = 10.95). Compared with controls, caregivers in the intervention group displayed significantly greater improvement in sleep quality, as well as perceptions of positive aspects of caregiving and reduction of depression. Most participants were very satisfied with the intervention. These findings suggest that individual telephone-based BA interventions are feasible, acceptable, and effective in improving sleep quality and psychological health in family caregivers of PWD. These results contribute to the literature by providing evidence for developing effective, accessible, and sustainable BA interventions for family caregivers of PWD.

Discrepancy between self-reported and objective sleep duration among dementia caregivers and noncaregivers

STUDY OBJECTIVES

Poor 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.

METHODS

This 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.

RESULTS

Caregivers 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.

CONCLUSIONS

The 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.

Cognitive Function and Sleep in Caregivers of Persons Living with Dementia

Poor sleep is prevalent among caregivers of persons living with dementia and increases their risk for cognitive impairment and decline. In this cross-sectional, correlational study, we compared the cognitive function scores of caregivers with poor sleep with the demographically adjusted normed scores of the National Institutes of Health Toolbox Cognition Battery. Caregivers completed a 14-day sleep diary. On average, caregivers (n = 28) were 65.14 (±10.08) years, female, and White. Their average crystallized cognitive function composite score was significantly higher and their average fluid cognitive function composite score was significantly lower than the normative scores. Caregivers performed significantly worse on the processing speed domain measure. Poor sleep may affect how caregivers, including highly educated caregivers, process and respond to information, thus can influence how they safely perform complex caregiving tasks. Health care providers should consistently assess caregivers' sleep and cognitive abilities to promptly identify changes and provide timely interventions.

Prevalence and Associated Factors with Poor Sleep Quality in Non-Professional Caregivers

This study aimed to determine the prevalence and associated factors of poor sleep quality in non-professional caregivers. With this purpose, cross-sectional data were collected from 201 dependent people's family caregivers using the Pittsburgh Sleep Quality Index (PSQI), the Caregiver Burden Inventory (CBI), the General Health Questionnaire (GHQ-12), and an ad hoc questionnaire to obtain sociodemographic data. A total of 153 family caregivers were categorized as poor sleepers (PSQI > 5), resulting in a prevalence of poor sleep quality of 76.1% (95% CI = 70.5-82.5). Poor sleepers were more likely to care for persons with mental disorders (χ2 = 7.31; p < 0.01) and scored significantly higher on perceived burden (z = -4.44; p < 0.001), psychological distress (z = -6.24; p < 0.001), and in all the PSQI subscales (p < 0.001), compared with good sleepers (PSQI ≤ 5). By contrast, no differences were found between poor and good sleepers in age, gender, years providing care, and daily hours of care. Multiple linear regression analysis showed that the factors of caregiver burden (β = 0.15; p < 0.05) and psychological distress (β = 0.53; p < 0.001) were significantly associated with sleep quality in dependent people's family caregivers. Cognitive-behavioral strategies to improve sleep quality in the primary health care of family caregivers are suggested.

Caregiving stress and burden associated with cardiometabolic risk in family caregivers of individuals with cancer

Chronic stress is a well-established risk factor for cardiometabolic disease. Caregiving for individuals with cancer is perceived as a chronic stressor yet research on the risk for cardiometabolic disease in this population, opposed to the elderly and those with Alzheimer's disease, is limited. Additionally, few studies have explored the early physiological changes that occur in family caregivers suggesting an elevated risk for illness. This cross-sectional study was designed to examine levels of cardiometabolic risk biomarkers and their correlates in caregivers of patients with colorectal cancer. Caregivers completed questionnaires that measure exposures to stress and vulnerability factors, psychological distress, and health habits as potential correlates. Traditional lipid and nontraditional lipoprotein particle biomarkers (e.g. concentration and size for all lipoprotein classes) were assayed from blood serum. Caregivers (N = 83, mean age = 49.8, 73% female) displayed levels of cardiometabolic biomarkers that suggest an elevated risk for cardiometabolic disease. Caregivers who were Hispanic, married, highly educated, employed, reported more hours spent caregiving daily, experienced higher caregiver burden associated with the lack of family support and impact on schedule, and psychological distress, demonstrated an elevated risk for cardiometabolic disease; primarily determined by nontraditional lipid biomarkers - large TRL-P, LDL-P, small HDL-P, large HDL-P, TRL-Z, LDL-Z and HDL-Z. These findings suggest that traditional lipid biomarkers may not be robust enough to detect early physiological changes associated with cardiometabolic disease risk in family caregivers. Moreover, findings reiterate the importance of assessing caregiver burden and providing evidence-based interventions to manage caregiving stress with the potential to improve caregivers' cardiometabolic health.

Association Between Cohabitation Status and Sleep Quality in Families of Persons With Dementia in Korea: A Cross-sectional Study

Objectives

The aim of this study was to identify the association between cohabitation status and sleep quality in family members of people with dementia (PwDs).

Methods

Data of 190 365 participants aged ≥19 years from the 2018 Korea Community Health Survey were analyzed. Participants were categorized according to their cohabitation status with PwDs. Multiple logistic regression and ordinal logistic regression analyses were performed to evaluate the relationship between the cohabitation status of PwDs’ relatives and sleep quality measured using the Pittsburgh Sleep Quality Index (PSQI) and PSQI subscales.

Results

Compared to participants without PwDs in their families, both cohabitation and non-cohabitation with PwDs were associated with poor sleep quality (cohabitation, male: odds ratio [OR],1.28; 95% confidence interval [CI], 1.08 to 1.52; female: OR, 1.40; 95% CI, 1.20 to 1.64; non-cohabitation, male: OR, 1.14; 95% CI, 1.05 to 1.24; female: OR, 1.23; 95% CI, 1.14 to 1.33). In a subgroup analysis, non-cohabiting family members showed the highest odds of experiencing poor sleep quality when the PwD lived alone (male: OR, 1.48; 95% CI, 1.14 to 1.91; female: OR, 1.58; 95% CI, 1.24 to 2.01). Cohabiting male and female participants had higher odds of poor subjective sleep quality and use of sleeping medications than non-cohabiting male and female participants, respectively.

Conclusions

The residence of PwDs and cohabitation status may contribute to poor sleep quality among PwDs’ family members. The circumstances faced by cohabiting and non-cohabiting family members should be considered when evaluating sleep quality in family members of PwDs, and appropriate interventions may be needed to improve sleep quality in both cohabiting and non-cohabiting family members.

Family functionality and burden of family caregivers of users with mental disorders

OBJECTIVE

to verify the difference of mean or median in the scores of family functionality and burden of family caregivers of people with mental disorders.

METHODS

cross-sectional study carried out in a Psychosocial Care Center with 61 family caregivers. Instruments were used for sociodemographic characterization, care process, Family Apgar Index and Family Burden Interview Schedule. Mean/median difference tests were adopted.

RESULTS

women with mental disorders and the presence of children in the home decreased the median of the family Apgar score. Difficulty in the relationship between caregiver/user, nervousness/tension, physical aggression and agitation of patients increased the global average of subjective burden.

CONCLUSIONS

nursing interventions to reduce burden and promote family functionality should prioritize caregivers of women with mental disorders, assist them in managing troublesome behaviors and raising awareness of family nucleus to co-responsibility for caring for sick people, especially in families with children who demand daily care.

Informal caregiver experiences at the end-of-life of individuals living with dementia with Lewy bodies: An interview study

Individuals with dementia with Lewy bodies (DLB) commonly die from dementia-related causes, but little is known regarding caregiver experiences during the end-of-life period in DLB. This reflects a critical knowledge gap given the high frequency of informal caregiving for individuals with dementia, high caregiver burden in DLB, and the fact that most individuals with DLB die from this disease. Investigators conducted telephone interviews with family members of individuals who died with DLB in the last 5 years. Investigators used a qualitative descriptive approach to analyze interview transcripts. Participants included 15 children, 13 spouses, and 2 other family members. Interviews averaged 31 min. Major themes included caregivers as the main drivers of care for individuals with DLB throughout the disease course and at the end of life, the impact of DLB features (e.g., fluctuations, hallucinations, and delusions) on end-of-life experiences, experiences relating to the caregiving role, death and post-death experiences, and supports employed by caregivers in the end-of-life period. End-of-life experiences for caregivers of individuals with DLB built on the accumulated burden of the disease course, where caregivers were often responsible for driving DLB care-from making the diagnosis to educating healthcare professionals and double-checking medical decisions. While some end-of-life experiences were consistent with those described in dementia palliative care more generally (e.g., financial stresses, poor sleep, being overwhelmed, and needing increased education and support), many DLB features specifically affected end-of-life caregiver experiences, such as the presence of delusions. Improving caregiver experiences at the end of life in DLB will require improved diagnosis and care for individuals with DLB throughout the disease course and also better strategies for treating behavioral symptoms. More research is needed regarding drivers of quality end-of-life experiences for individuals with DLB and their families and how drivers and strategies may differ between dementias.

Psychometric properties of the Insomnia Severity Index in a sample of family dementia caregivers

STUDY OBJECTIVES

Family caregivers of people with dementia frequently report sleep problems that are linked to depressive and anxious symptoms. However, data are needed regarding the psychometric properties of specific measures of sleep problems in caregiving populations. The aim of this study is to analyse the psychometric properties of the Insomnia Severity Index (ISI; Morin, 1993) in a Spanish dementia caregiver sample.

METHODS

271 participants took part in face-to face interviews where, along with sociodemographic variables, caregivers' sleep problems, depressive and anxious symptoms were measured. The psychometric properties of the ISI were analysed through Confirmatory Factor Analysis (CFA) and analysis of the internal consistency and convergent and criterion validity.

RESULTS

The Spanish version of the Insomnia Severity Index showed adequate indices of internal consistency (Cronbach's alpha = 0.78) in our sample of family caregivers of people with dementia. A one-factor structure provided a better fit to the data than two- and three-factor structures. The ISI was significantly associated with lower sleep quality, less average sleep time per day and lower self-perception of vitality, as well as with higher depressive and anxious symptoms. Differences in ISI scores were found between people with and without depressive and anxious symptoms. Statistically significant gender-based differences in sleep problems were also found, with female caregivers showing higher sleep problems.

CONCLUSIONS

The ISI is a reliable and valid instrument to assess the subjective severity of sleep problems in the family dementia caregiver population and may be a useful instrument in intervention and research settings. Additional evidence was also provided of the importance of considering sleep problems in the studied population.

Sleep Disruption Due to Stress in Women Veterans: A Comparison between Caregivers and Noncaregivers

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.

Sleep, Mild Cognitive Impairment, and Interventions for Sleep Improvement: An Integrative Review

Sleep disturbance in mild cognitive impairment (MCI) is associated with progression to Alzheimer's disease (AD), more severe AD symptoms, and worse health outcomes. The aim of this review was to examine the relationship between sleep and MCI, and the effectiveness of sleep improvement interventions for older adults with MCI or AD. An integrative review was conducted using four databases, and findings were analyzed using an iterative process. Findings from 24 studies showed that alterations in sleep increased the risk of MCI and that the sleep quality of individuals with MCI or AD was poorer than healthy controls. Changes in brain anatomy were also observed in healthy older adults with sleep disturbances. Examined interventions were shown to be effective in improving sleep. Screening for sleep disturbances in individuals with MCI/AD is crucial to mitigate neurodegenerative or neurobehavioral risks in this population.

Disrupted sleep and associated factors in Australian dementia caregivers: a cross-sectional study

BACKGROUND

Sleep disturbance is an issue reported by caregivers. Waking at night is a feature of dementia and by proxy, sleep disturbance among caregivers is reported to be high. Little is known about the characteristics of dementia caregivers' sleep and the factors that may influence sleep disruption. The purpose of this study was to investigate the sleep characteristics and disturbances of Australian caregivers of a person living with dementia. In addition, it evaluated the psychological wellbeing of caregivers by evaluating associations between mood and sleep in this population.

METHODS

This study used a cross-sectional, descriptive, correlation design. Participants were recruited with the assistance of Alzheimer's Australia, Dementia Australia and targeted social media advertising. In total, 104 adult, primary, informal caregivers of people with dementia participated, completing a questionnaire on demographic characteristics, the Depression, Anxiety and Stress Scale (DASS-21) and the Pittsburgh Sleep Quality Index (PSQI).

RESULTS

In this study, 76% of caregivers were female who had been caring for someone living with dementia on average for 4.8 years. 44% of participants had two or more co-morbidities namely cardiovascular disease, osteoarthritis and diabetes. 94% of participants were poor sleepers with 84% with difficulty initiating sleep and 72% reporting having difficulty maintaining sleep. Overall, psychological distress was common with high levels of moderate to severe depression, anxiety and stress. Global PSQI scores were significantly positively associated with depression and anxiety, with the strongest correlation seen with stress scores. Depression scores were also moderately associated with daytime dysfunction. Stress was identified as a significant predictor of overall sleep quality.

CONCLUSIONS

Sleep problems are common within the population of dementia caregivers. Due to the nature and duration of caregiving and the progression of dementia of the care recipient, there is the potential for a decline in the caregivers' mental and physical health. Caregivers of those living with dementia are more likely to have comorbidities, depression, anxiety and stress. Sleep quality is correlated with emotional distress in dementia caregivers although the direction of this association is unclear. Therefore, sleep and psychological wellbeing may be intertwined, with improvements in one aspect resulting in a positive impact in the other.

Effectiveness of Self-administered Acupressure for Family Caregivers of Advanced Cancer Patients With Insomnia: A Randomized Controlled Trial

BACKGROUND

Sleep disturbances are common among family caregivers (FCs) of patients with advanced cancer. Self-administered acupressure can combat insomnia, but no study has been conducted to evaluate its efficacy in caregivers of patients with advanced cancer.

OBJECTIVE

The aim of this study is to investigate whether self-administered acupressure improves sleep quality for FCs of patients with advanced cancer.

METHODS

Family caregivers of patients with advanced cancer who reported sleep disturbance (Pittsburgh Sleep Quality Index scores >5 in recent months) were recruited. The experimental group self-administered acupressure at the Baihui (GV20), Fengchi (GB20), Neiguan (PC6), and Shenmen (HT7) points over a 12-week period, whereas the comparison group received sleep hygiene education. Sleep quality was assessed subjectively at 4, 8, and 12 weeks after the intervention using the Pittsburgh Sleep Quality Index and objectively using actigraphy measurements. Improvements in sleep quality were analyzed using a generalized estimating equation.

RESULTS

Compared with the control group, the experimental group demonstrated significantly lower sleep latency (Wald χ2 = 11.49, P = .001) and significantly better sleep efficiency (Wald χ2 = 5.24, P = .02) according to actigraphy measurements, but Pittsburgh Sleep Quality Index scores did not differ significantly between the groups.

CONCLUSIONS

Self-administered acupressure did not demonstrate favorable effects on subjective sleep quality, but did reduce sleep latency and improve sleep efficiency, according to actigraphy measurements. Self-administered acupressure may help relaxation and sedation and promote sleep in FCs.

IMPLICATIONS FOR PRACTICE

Healthcare providers may consider advising FCs to apply this self-administered acupressure to improve their sleep latency and sleep efficiency.

The impact of sleep disturbances on care home residents with dementia: the SIESTA qualitative study

OBJECTIVES

Nearly 40% of care home residents who are living with dementia also have symptoms of disturbed sleep. However, the impact of these disturbances is relatively unknown and is needed to indicate whether interventions are warranted; therefore, we aimed to investigate the impact.

DESIGN

One-to-one semi-structured interviews.

SETTINGS

Four UK care homes.

PARTICIPANTS

We interviewed 18 nurses and care assistants about residents with sleep disturbances.

MEASUREMENTS

We used a topic guide to explore staff experience of sleep disturbance in residents with dementia. The interviews were audio recorded and transcribed and then analyzed thematically by two researchers independently.

RESULTS

Staff described that sleep disturbances in most, but not all, residents impacted negatively on the resident, other residents, staff, and relatives. Residents became more irritable or agitated if they had slept badly. They slept in the daytime after a bad night, which then increased their chances of being awake the following night. For some, being sleepy in the day led to falls, missing medication, drinks, and meals. Staff perceived hypnotics as having low efficacy, but increasing the risk of falls and drowsiness. Other residents were disturbed by noise, and staff described stress when several residents had sleep disturbance. Some of the strategies reported by staff to deal with sleep disturbances such as feeding or providing caffeinated tea at night might be counterproductive.

CONCLUSIONS

Sleep disturbances in care home residents living with dementia negatively affect their physical and psychological well-being. These disturbances also disturb other residents and increase stress in staff.

Effectiveness of Respite Care via Short-Stay Services to Support Sleep in Family Caregivers

Family caregivers of older people who need care often experience sleep disorders, which can lead to various health problems. Although respite care is used in many countries, its effectiveness has not been fully demonstrated. We analyzed the sleep of family caregivers using actigraphy and heart rate spectral analysis to clarify changes in their sleep characteristics during short-stay respite care. Participants were all family caregivers living with an older person needing long-term care. The outcomes consisted of questionnaire responses, sleep/wake records, and R-wave to R-wave interval records. Quantitative evaluation of sleep revealed that caregivers’ median sleep time was 378.0 min, and median sleep efficiency was 94.7%. The low frequency (LF)/high frequency (HF) value was 1.722 for total sleep and 1.822 for the first half of the sleep period. The LF/HF for the first half of the sleep period was significantly different between caregiving and respite days. The respite day LF/HF was 1.567, which was significantly lower than on caregiving days. On respite days, cardiac sympathetic nervous activity among family caregivers was reduced during the first half of the sleep period. This suggests that regular use of short-stay services can improve caregivers’ sleep status, making this an effective form of respite care.

"It's Been a Hard Day's Night": Sleep Problems in Caregivers for Older Adults

PURPOSE OF REVIEW

This paper critically evaluates literature from the last three years on sleep in caregivers for older adults. Research is evaluated in four main areas: factors related to caregivers having sleep problems, sleep health in various types of caregivers, how caregivers' sleep and health inter-relate, and interventions to improve sleep.

RECENT FINDINGS

A range of both care recipients' and caregivers' characteristics have been associated with caregiver sleep quality measured subjectively and objectively. Care recipient factors associated with caregiver sleep quality include fall risk and sleep quality, while caregiver factors include stress, duration, intensity, provision of medical/nursing care tasks, and even particular serotonin genotypes (e.g. short allele carriers for 5-HTTLPR). While the greatest focus has been on dementia caregivers, recent work suggests groups such as end-of-life caregivers, former caregivers, and caregivers with multiple care roles (e.g. child, older adult, paid care) have sleep disturbances that vary by their unique contexts. Caregiver's sleep, particularly subjective assessments, relates to their mood and physiological well-being; and evidence suggests that sleep may be an important mediator linking care stressors with mental health. Factors such as mindfulness and sense of coherence may protect caregivers from sleep disturbances.

Caregiver Burden and Sleep Quality in Dependent People's Family Caregivers

This study examined the relationship between caregiver burden and sleep quality in dependent people’s family caregivers. A cross-sectional study was carried out with 201 dependent people’s family caregivers and 92 non-caregivers controls. Participants completed the Pittsburgh Sleep Quality Index (PSQI), the Caregiver Burden Inventory (CBI), and an ad-hoc questionnaire to collect sociodemographic data. Based on CBI scores, subjects were categorized into three groups: family caregivers with high levels of perceived burden, family caregivers with low and medium levels of perceived burden and non-caregiver controls. There were significant differences among the groups in the PSQI total (F = 40.39; p < 0.001), subjective sleep quality (F = 25.55; p < 0.001), sleep latency (F = 16.99; p < 0.001), sleep disturbances (F = 14.90; p < 0.001), use of sleep medications (F = 6.94; p < 0.01) and daytime dysfunction (F = 20.12; p < 0.001). These differences were found only between the caregivers with high levels of perceived burden and the other two groups (p < 0.05). There were also significant differences between the groups in sleep duration (F = 18.34; p < 0.001) and habitual sleep efficiency (F = 24.24; p < 0.001). In these dependent measures, the differences were found in all the pairs examined (p < 0.05). These results suggest that caregiver burden is related to sleep quality, so that caregivers with greater perceived burden have a worse sleep quality.
