Informal Care and Sleep Disturbance Among Caregivers in Paid Work: Longitudinal Analyses From a Large Community-Based Swedish Cohort Study

Effects of a workplace participatory approach to support working caregivers in balancing work, private life and informal care: a randomized controlled trial

OBJECTIVES

Many employees combine their work with informal care responsibilities for family and friends, potentially impacting their well-being and sustained employability. This study aimed to investigate the effectiveness of a workplace participatory approach (PA) intervention in supporting working caregivers to prevent and solve problems related to balancing work, private life, and informal care tasks.

METHODS

We conducted a two-armed randomized controlled trial (ISRCTN15363783) in which working caregivers either received the PA (N=57), under guidance of an occupational professional serving as process facilitator, or usual care (N=59). We recruited 125 working caregivers from four Dutch organizations. Questionnaire-based measurements were assessed at baseline, 4, and 7 months. The primary outcome was work-life imbalance. Secondary outcomes were perceived social support from supervisors and colleagues, role overload, distress and perceived burden of combining work and informal care. Intervention effects were analyzed using intention-to-treat analysis and linear mixed models.

RESULTS

The PA was not effective in reducing work-life imbalance, improving support from colleagues or reducing role overload, distress and perceived burden of combining work and informal care. However, the PA significantly improved perceived social support from supervisors at 4 months [β=0.54, 95% confidence interval (CI) 0.21-0.88] and 7 months (β=0.36, 95% CI 0.02-0.70). Interaction effects indicated that improvement in supervisor support varied depending on the organization.

CONCLUSION

The PA improved supervisor support but not work-life imbalance. Further research should explore PA effects on working caregivers with and without balance issues and the role of supervisor support in reducing work-life conflict.

Sleep Disturbance, Mental Health Symptoms, and Quality of Life: A Structural Equation Model Assessing Aspects of Caregiver Burden

OBJECTIVES

The present study sought to examine the association between sleep disturbance, mental health symptoms, and quality of life among informal caregivers. The study also aimed to assess whether greater caregiver demands (i.e., hours spent providing care per week) altered the associations between these physical and mental health outcomes.

METHODS

530 informal caregivers participated in an online study of sleep and health across the lifespan. Sleep disturbance was assessed via the Insomnia Severity Index and RU-SATED. Mental health was measured using the PHQ-2, GAD-2, and the PANAS. Quality of life was assessed via the Satisfaction with Life Scale.

RESULTS

Results revealed an indirect association between sleep disturbance and quality of life via increased mental health symptoms (β = -.21, p =.001). This indirect association was moderated by caregiver demands (β =.33, p =.002), with higher caregiving demands increasing the association between sleep disturbance and quality of life.

CONCLUSIONS

Findings highlight the adverse outcomes associated with sleep disturbance among caregivers and suggest that higher caregiving demands increases the effect of sleep disturbance on quality of life.

CLINICAL IMPLICATIONS

Increased caregiving is associated with adverse physical and mental health consequences. Assessing and treating sleep disturbance among caregivers is needed and may lead to improvements in mental health and quality of life.

Informal caregiving and the allocation of time: implications for opportunity costs and measurement

Informal care requires a considerable time investment from providers that inherently involves trade-offs against various uses of time. We examine what other uses of time are forgone when individuals provide informal care. We further consider how caregiving is linked to a range of rarely explored time use characteristics relating to multitasking, the fragmentation and the timing of activities. We use data from 5670 adults across 11003 diary days from the 2014/15 UK Time Use Survey. Using a 'doubly robust' approach of entropy balancing and regression adjustment, we find carers spend an additional 49.0 min on non-market work, 2.9 min on personal care, 5.8 min on leisure and 2.9 min on miscellaneous activities on weekdays. They spend 46.1 min less on market work and 14.4 min less on sleep. Carers report more time stress, more multitasking, and more fragmented time. We estimate with attribution factors that 16% and 11% of reported household task activity is due to caregiving on weekday and weekend days, respectively. These findings provide evidence on additional opportunity costs faced by carers and possible channels through which carer labour market and health outcomes are realised. The attribution factors we calculate can be applied to total reported caregiving time to avoid overestimation when this is incorporated into economic evaluations.

Informal caregiving, time use and experienced wellbeing

Informal carers report lower evaluative wellbeing than non-carers. In contrast to this literature and our own analysis of evaluative wellbeing, we find carers have a small but higher level of experienced wellbeing than non-carers do. To investigate why, we use decomposition analysis which separates explanatory factors into how time is used and how those uses of time are experienced. We analyze activities and associated experienced wellbeing measured in ten-minute intervals over two days by 4817 adults from the 2014/15 UK Time Use Survey. We use entropy balancing to compare carers with a re-weighted counterfactual non-carer group and then apply Oaxaca-Blinder decomposition. The experienced wellbeing gap of 0.066 is the net result of several substantial competing effects of time use. Carers experienced wellbeing would be higher by 0.188 if they had the same patterns and returns to time use as non-carers which is driven by sleep, time stress and alternative characteristics of time use. However, leisure and non-market activities serve to dampen this increase in experienced wellbeing. Initiatives to improve and assess carer wellbeing should pay close attention to how carers spend their time.

How does beginning or ceasing of informal caregiving of individuals in poor health influence sleep quality? Findings from a nationally representative longitudinal study

BACKGROUND

Various cross-sectional studies exist examining the association between informal caregiving and sleep quality. However, there is a lack of longitudinal studies investigating whether beginning and ceasing of informal caregiving is associated with changes in sleep quality.

AIMS

Investigating whether beginning and ceasing of informal caregiving of individuals in poor health is associated with changes in sleep quality in both sexes.

METHODS

Data were taken from a nationally representative sample of individuals ≥ 40 years in Germany from 2008 to 2017. In our analytical sample, n equaled 22,910 observations. Based on the Pittsburgh Sleep Quality Index, the sleep quality was assessed by the difficulties falling asleep during the last month, difficulties with sleep because of waking up during the last month (in both cases: (from 1 = not during the last month to 4 = three or more times a week) and the overall assessment of sleep quality during the last month (from 1 = very good to 4 = very bad).

RESULTS

Asymmetric fixed effects regressions showed that in men beginning to provide informal care was associated with decreased overall sleep quality (β=-.09 (95% CI: -.15 - -.03), p<.01) and an increased likelihood of difficulties because of waking up (OR: 1.54 (95% CI: 1.07-2.20), p<.05), whereas ceasing to provide informal care was not associated with the outcome measures (both, in women and in men).

DISCUSSION

Starting informal caregiving had deleterious effects on sleep quality in men.

CONCLUSIONS

Efforts to assist men in maintaining sleep quality may be beneficial.

Work changes and employee age, maladaptive coping expectations, and well-being: a Swedish cohort study

Purpose

Older workers are expected to suffer more from work changes than younger ones, but empirical evidence is lacking. Negative responses to work changes may result rather from maladaptive coping expectations. This study examined possible age differences in job and life satisfaction, and sleep disturbances, after work changes (voluntary and involuntary job changes, reorganizations) and the moderating role of maladaptive coping expectations.

Methods

Four biennial waves from the Swedish Longitudinal Occupational Survey of Health (SLOSH) including respondents who participated in all four waves (n = 3084). We used multilevel path analyses to estimate direct and moderated relationships between work changes and outcomes.

Results

Involuntary job changes were associated with lower job and life satisfaction and more sleep disturbances. Reorganizations were only associated with lower job satisfaction. Older employees were more satisfied with their jobs and lives than younger employees and experienced more sleep disturbances. After involuntary job changes, older employees had similar (lower) levels of well-being as younger ones, but they reported more sleep disturbances when having experienced reorganizations. Maladaptive coping expectations were related to lower job and life satisfaction and more sleep disturbances. Employees with maladaptive coping expectations reported more sleep disturbances after involuntary job changes and reorganizations.

Conclusion

Our results suggest that there are few age differences in well-being after work changes. Employee well-being seems to mostly depend on maladaptive coping expectations. Organizations aiming to prepare employees for job changes and reorganizations could focus their efforts on employees with maladaptive expectations rather than on older ones.

A Systematic Review of Sleep and Circadian Rhythms in Children with Attention Deficit Hyperactivity Disorder

OBJECTIVE

Children and adults with ADHD often report sleep disturbances that may form part of the etiology and/or symptomatology of ADHD. We review the evidence for sleep changes in children with ADHD.

METHODS

Systematic review with narrative synthesis assessing sleep and circadian function in children aged 5 to 13 years old with a diagnosis of ADHD.

RESULTS

148 studies were included for review, incorporating data from 42,353 children. We found that sleep disturbances in ADHD are common and that they may worsen behavioral outcomes; moreover, sleep interventions may improve ADHD symptoms, and pharmacotherapy for ADHD may impact sleep.

CONCLUSION

Sleep disturbance may represent a clinically important feature of ADHD in children, which might be therapeutically targeted in a useful way. There are a number of important gaps in the literature. We set out a manifesto for future research in the area of sleep, circadian rhythms, and ADHD.

Care to sleep? Daily caregiving and sleep problems in an ageing European population

Informal caregiving is increasingly common in our ageing population and entering the role of informal caregiver generally marks an important life course transition. The adjustment to such transitions is considered important for the onset of sleep problems. Therefore, this study aims to establish how becoming a daily caregiver is associated with sleep problems, if changes in caregiving status are related to changes in sleep problems and how intersections with other social roles affect this association. Based on data from waves 1, 2, 4, 5 and 6 of the Survey of Health Ageing and Retirement in Europe (N=32,791), the analyses show how both current and former daily caregivers are more likely to report sleep problems than those not giving daily care. When change in sleep problems is assessed a transition to daily caregiving appears to be accompanied by increased sleep problems. Moreover, even individuals who ceased giving care experience more sleep problems than those who never gave care on a daily basis, which suggests a legacy of caregiving. No differences are found regarding employment status, but women who start giving care are more likely to experience sleep problems than their male counterparts.

Shift work, work time control, and informal caregiving as risk factors for sleep disturbances in an ageing municipal workforce

Objectives:

This study aimed to examine the contribution of shift work, work time control (WTC) and informal caregiving, separately and in combination, to sleep disturbances in ageing employees.

Methods:

Survey data were obtained from two prospective cohort studies with repeated measurements of working conditions, informal caregiving, and sleep disturbances. We used fixed-effect conditional logistic regression analysis to examine whether within-individual changes in shift work, WTC and informal caregiving were associated with changes in sleep. Secondary analyses included between-individuals comparison using standard logistic regression models. Results from the two cohorts were pooled using meta-analysis.

Results:

Low WTC and informal caregiving were associated with sleep disturbances in within-individual analyses [odds ratios (OR) ranging between 1.13 (95% confidence interval 1.01–1.27) and 1.48 (95% CI 1.29–1.68)] and in between-individuals analyses [OR 1.14 (95% CI 1.03–1.26) to 1.33 (1.19–1.49)]. Shift work alone was not associated with sleep disturbances, but accumulated exposure to shift work, low WTC and informal caregiving was associated with higher risk of sleep disturbances (OR range 1.21–1.76). For some of the sleep outcomes, informal caregiving was related to a higher risk of sleep disturbances when WTC was low and a lower risk when WTC was high.

Conclusions:

Informal caregiving and low WTC are associated with risk of sleep disturbances among ageing employees. The findings also suggest that low WTC in combination with informal caregiving may increase the risk of sleep disturbances whereas high WTC may alleviate the adverse impact of informal caregiving on sleep.

Informal Caregiving, Chronic Physical Conditions, and Physical Multimorbidity in 48 Low- and Middle-Income Countries

BACKGROUND

The health of the caregivers is crucial to sustain informal care provision, while multimorbidity is an important health risk concept. However, studies on the association between informal caregiving and physical multimorbidity are currently lacking. Therefore, we investigated this association in adults from 48 low- and middle-income countries (LMICs).

METHOD

Cross-sectional data from 242,952 adults (mean age 38.4 years) participating in the World Health Survey 2002-2004 were analyzed. Informal caregivers were considered those who provided help in the past year to a relative or friend (adult or child) who has a long-term physical or mental illness or disability, or is getting old and weak. Nine physical conditions were assessed. Multivariable logistic regression analyses were conducted to assess associations between informal caregiving and physical multimorbidity, while the between-country heterogeneity in this relationship was studied with country-wise analyses.

RESULTS

The overall prevalence of informal caregiving and physical multimorbidity (ie, two or more physical conditions) was 19.2% and 13.2%, respectively. Overall, caregivers had 1.40 (95% confidence interval = 1.29-1.52) times higher odds for physical multimorbidity. This association was particularly pronounced in younger caregivers (eg, 18-44 years: odds ratio = 1.54; 95% confidence interval = 1.37-1.72), whereas this association was not statistically significant among those aged ≥65 and older (odds ratio = 1.19; 95% confidence interval = 0.98-1.44). Country-wise analyses corroborated these findings, and there was a negligible level of between-country heterogeneity (I2 = 24.0%).

CONCLUSIONS

In LMICs, informal caregivers (especially young caregivers) were more likely to have physical multimorbidity. This should be taken into account in policies that address the health and well-being of informal caregivers.

Is combining human service work with family caregiving associated with additional odds of emotional exhaustion and sickness absence? A cross-sectional study based on a Swedish cohort

PURPOSE

The aim of the study is to examine to what extent human service work and family caregiving is associated with emotional exhaustion and sickness absence, and to what extent combining human service work and family caregiving is associated with additional odds.

METHODS

Data were derived from participants in paid work from the Swedish Longitudinal Occupational Survey of Health, year 2016 (n = 11 951). Logistic regression analyses were performed and odds ratios and 95% confidence intervals estimated for the association between human service work and family caregiving, respectively, as well as combinations of the two on one hand, and emotional exhaustion and self-reported sickness absence on the other hand. Interaction between human service work and family caregiving was assessed as departure from additivity with Rothman's synergy index.

RESULTS

Human service work was not associated with higher odds of emotional exhaustion, but with higher odds of sickness absence. Providing childcare was associated with higher odds of emotional exhaustion, but lower odds of sickness absence, and caring for a relative was associated with higher odds of both emotional exhaustion and sickness absence. There was no indication of an additive interaction between human service work and family caregiving in relation to neither emotional exhaustion nor sickness absence.

CONCLUSIONS

We did not find support for the common assumption that long hours providing service and care for others by combining human service work with family caregiving can explain the higher risk of sickness absence or emotional exhaustion among employees in human service occupations.

Reciprocal relations between work stress and insomnia symptoms: A prospective study

Work stress and poor sleep are closely related in cross-sectional data, but evidence from prospective data is limited. We analysed how perceived stress and work stressors (work demands, decision authority and workplace social support) are related to key dimensions of insomnia over time, using structural equation modelling. Biennial measurements from a large sample of the working population in Sweden enabled us to analyse both the relationship from stress to sleep as well as that from sleep to stress. Overall, we found reciprocal relations between insomnia and all four stress measures. However, looking at the relation between each dimension of insomnia and each stress measure, there were some differences in direction of effects. In the direction from stress to sleep, all work stressors as well as perceived stress predicted both difficulties initiating sleep and difficulties maintaining sleep. The same was found for non-restorative sleep, with the exception for decision authority. In the opposite direction, difficulties maintaining sleep predicted increased levels of work demands and perceived stress. Difficulties initiating sleep stood out among the insomnia symptoms as not predicting any of the stress measures, while non-restorative sleep was the only symptom predicting all stress measures. The results advance the understanding of the stress-sleep relationship and indicate a potential vicious circle between insomnia and perceived stress as well as work stressors, suggesting that the workplace could be an arena for interventions to alleviate insomnia.

Co-resident care-giving and problematic sleep among older people: evidence from the UK Household Longitudinal Study

In light of current pressures within formal social care services, informal carers assume an important role in meeting the care needs of a growing number of older people. Research suggests relationships between care-giving and health are complex and not yet fully understood. Recently, wide-ranging associations between sleep and health have been identified, however, our understanding of the links between care-giving and sleep is limited at present. This study assesses longitudinal patterns in co-resident care-giving and problematic sleep among older people in the United Kingdom. Our sample included 2,470 adults aged 65 years and older from the UK Household Longitudinal Study. Problematic sleep was defined as two or more problems in going to sleep, staying asleep or sleep quality. Using logistic regression models, we assessed how co-resident care-giving status, intensity and transitions influence the likelihood of problematic sleep in the following year, adjusting for potential confounding factors. Adjusted analyses found co-resident care-givers were 1.49 (95% confidence interval = 1.06–2.08) times more likely to report problematic sleep in the following year, relative to those not providing care. Care-giving over 20 hours per week and continuous co-resident care-giving also significantly increased the odds of problematic sleep. This suggests older co-resident care-givers may be at greater risk of incurring sleep problems than non-care-givers. Further longitudinal research is needed to investigate care-giver-specific consequences of poor sleep.
