Grounded in and expanding upon the allostatic load model, the present study examined how repeated exposure to work and nonwork stressors (i.e., stressor pile-up) across an 8-day study period relates to daily strain-related outcomes—diurnal cortisol, physical symptoms, and sleep quantity and quality—in both parents and their adolescent children. Non...

Study Objectives This study investigated whether disability status increased with the frequency of insomnia symptoms and sleep medication usage over a 5-year period and whether frequent use of sleep medication modified the longitudinal effects of insomnia symptoms on disability among community-dwelling older adults. Methods Data were from the Nati...

Background Understanding the differences between various instruments for assessing depression will help researchers and health practitioners to choose a more appropriate tool and develop a framework to enhance resilience to mental health problems in the older population. The current study aimed to compare the 10-item Center for Epidemiological Stud...

Sleep is essential for proper function of the mind and body. Studies report the effect of sleep problems on cognition but focus on only a single or limited number of sleep indicators or on clinical populations (e.g., sleep apnea), and/or provide only cross-sectional results. This study examined cross-sectional and longitudinal associations between...

Subjective cognitive decline is not a mere complaint by older adults; it is predictive of later development of objective cognitive decline and dementia. Sleep plays a pivotal role in maintaining cognitive, physical, and mental health, especially in older adults. While studies document age-related declines in sleep quality, limited research explores...

Existing research on spending time for others yields inconsistent findings regarding its effects on well-being. Some studies report positive effects, while others find negative effects. To address this inconsistency, our study explored whether spending time for others differentially impacts overall eudaimonic well-being and day-to-day hedonic well-...

Exercise has been shown to be a powerful tool that can improve cardiovascular health. Both exercise and adequate sleep have been associated with increased heart rate variability (HRV), while insufficient amounts of both are associated with decreased HRV. Yet, the combined influence of exercise and sleep on HRV is less clear. This study explores if...

Lifelong healthy habits are vital for healthy aging. This study examined the longitudinal associations of adherence to three key health behaviors (i.e., sleep, physical activity, healthy eating) on psychological well-being (PWB) and illnesses 10 years later. Data were from Midlife in the United States II and III (2005-2006, 2013-2017) participants...

Lifespan developmental theories highlight that aging is characterized by gains and losses across different domains (e.g., social, emotional, physical, cognitive). Such gains and losses translate into aging-related change in experiences across various facets of daily life. However, much of present theory and empirical evidence has focused on overall...

In 2014, Dr. Buysse published a seminal paper, titled “Sleep health: can we define it? Does it matter?” which proposed that sleep health extends beyond the absence of sleep disorders. He advocated for a preventive approach where individuals must address multiple aspects of sleep to support optimal functioning and health. The concept of sleep health...

As intensive longitudinal data collection becomes more widespread, innovative methods to quantify daily and momentary experiences are needed to advance theoretical understanding of daily life and its implications for successful aging. A particularly promising area of advancement is in quantitative summaries of rich categorical data regarding daily...

Sleep disturbances, dysregulated circadian rhythms, and related disorders can impact multiple aspects of life, including physical health, mobility, mental well-being, and other outcomes of relevance to aging populations. Treatments for specific disorders, such as Continuous Positive Airway Pressure (CPAP) for sleep apnea, are also important for pro...

Longitudinal evidence on the association between sleep and physical frailty is limited, especially using a multidimensional measure of sleep health. In this study, we examined the prospective association between sleep health and physical frailty among U.S. older adults. We also examined how this association differs by age, sex and race. We used dat...

Present theories on adult development and aging offer insights into how aging is characterized by gains and losses across different domains (e.g., social, emotional, physical, and cognitive). Such gains and losses are related to changes in behaviors and experiences across various facets of daily life. However, much of the literature has focused on...

Healthy sleep is essential to employee well-being and productivity, but many modern workers do not obtain adequate sleep. Are technology-related changes to job design (i.e., computer use, sedentary work, nontraditional work schedules) related to long-term worsening of employee sleep health? The present study seeks to address this question using nat...

Background Considering the significant growth in India’s aging population, it is imperative to identify factors associated with frailty among older Indians. This study examined the association between sleep quality, sleep duration, and physical frailty among older adults in India. Moreover, we examined whether the associations between sleep quality...

Objectives This study investigates the associations of retrospective reports of Recession hardships with 10-year changes in subjective and objective indicators of sleep, and whether these associations differ by race and gender. Methods Five hundred and one adults (14.57% Black; 54.49% female) from the Midlife in the United States (MIDUS) study rep...

Background Sleep problems are a critical issue in the aging population, affecting quality of life, cognitive efficiency, and contributing to adverse health outcomes. The coexistence of multiple diseases is common among older adults, particularly women. This study examines the associations between specific chronic diseases, multimorbidity, and insom...

This study investigated whether stress and positive anticipations about tomorrow are associated with emotional experiences the following day, mediated by the preceding night's sleep. Data were from 141 full-time nurses, utilizing a 14-day ecological momentary assessment combined with actigraphy sleep monitoring. Each evening, participants rated the...

Work may influence the home domain and subsequently impact employee sleep. Past work found that negative spillover mediated the relationship between perceived unfairness about work and insomnia symptoms across 20 years. As an extension of past work, this study investigated whether negative spillover and positive spillover mediate the relationship b...

While low back pain (LBP) may persist or recur over time, few studies have evaluated the individual course of LBP over a long-term period, particularly among older adults. Based on data from the longitudinal Osteoporotic Fractures in Men (MrOS) study, we aimed to identify and describe different LBP trajectories in older men and characterize members...

The experiences of family members are intertwined and the stressors of one family member may crossover to affect the wellbeing of others in the family as well. Prior studies have established that the stress experienced by one marital spouse can affect the wellbeing of their spouse and that parent stress can affect their children’s wellbeing. This s...

Objetivo: A pesar de la popularidad de la atención plena en las investigaciones y las intervenciones, falta información sobre cómo y por qué la atención plena puede beneficiar la salud del sueño de los empleados. A partir de la teoría de la regulación de las emociones, evaluamos la rumia afectiva, el afecto negativo y el afecto positivo como mecani...

Objective We evaluated whether more severe back pain phenotypes—persistent, frequent or disabling back pain—are associated with higher mortality among older men. Methods In this secondary analysis of a prospective cohort, the Osteoporotic Fractures in Men (MrOS) study, we evaluated mortality rates by back pain phenotype among 5215 older community-...

Background In addition to having higher negative affect and lower positive affect overall, depressed individuals exhibit heightened affective reactivity to external stimuli than non-depressed individuals. Sleep may contribute to day-to-day fluctuations in depressed individuals, given that sleep disturbance is a common symptom of depression. Yet, li...

Introduction Considering the significant growth in India's aging population, it is imperative to identify risk factors associated with frailty among older Indians. However, there is limited studies that assessed the linkage between sleep and frailty in this population and it is focused on sleep disorder. The purpose of this study was to examine the...

Objective To identify distinct sleep health phenotypes in adults, examine transitions in sleep health phenotypes over time and subsequently relate these to the risk of chronic conditions. Methods A national sample of adults from the Midlife in the United States study ( N = 3,683) provided longitudinal data with two timepoints (T1:2004-2006, T2:201...

Emerging research has shown that consecutive sleep loss impairs daily affective and physical well-being. Yet, little is known about the effects of consecutive poor sleep (in both quantity and quality) on daily cognitive stress. This study examined whether and how consecutive nights of poor sleep quantity and quality are associated with day-to-day t...

Sleep is often impaired in late life, raising concerns about the effect of poor sleep on mental and cognitive health in aging individuals. This symposium brings together five rigorous studies that show how poor sleep may be an under-recognized risk factor for mental health and cognitive outcomes in the second half of life. Specifically, this sympos...

Mounting evidence suggests poor sleep is associated with the development of chronic conditions. Numerous mechanisms for these links have been proposed, including inflammation, metabolic function, and brain structure. In this symposium, we will present five studies focused on links between poor sleep and subsequent development of chronic disease acr...

Stress impairs sleep. Poor sleep also increases the likelihood of stressful experiences. Importantly, there is the vicious cycle between stress and poor sleep, such that having either one increases the odds of the other. This is problematic in the context of aging, because midlife and older adults may have physiological vulnerability to stressors a...

Chronic conditions affect half of adults and are the leading cause of death in the United States. Healthy sleep is a modifiable risk factor, but greater information is needed about specific sleep experiences linked to chronic condition development. The present study aims to (1) identify within-person patterns of various sleep experiences (i.e., sle...

Black adults have higher risk for cardiovascular disease (CVD) compared to their White counterparts. Biopsychosocial frameworks suggest that this racial difference may not only be due to higher stressor exposure (e.g., discrimination) but also to stressor reactivity (i.e., heightened automatic reactions to stressors). This study examined if racial...

Negative and positive work experiences may spillover to the home domain and harm one’s sleep. This study investigated whether work-to-family spillover mediates the relationship between work characteristics and sleep health. Full-time workers (n=2,106) from the Midlife in the United States Study provided Time-1 data (T1: 2004-2006); a sub-set (n=1,4...

Alongside long-term change, lifespan theories highlight the importance of examining intraindividual variability (the fluctuations that occur in daily and momentary life) as an indicator of dynamic characteristics, like plasticity or rigidity. The present symposium demonstrates five unique characterizations and implications of variability in daily l...

Long-term negative impacts of chronic stress on memory has been well established; however day-to-day associations between stressors and memory have not been fully examined, with lack of understanding on specific manifestations of stressors that may degrade daily memory. This study conceptualized three patterns of daily stressors: variety, severity,...

Researchers have posited that healthcare workers (HCWs) are at greater risk of sleep and pain concerns due to their demanding work schedules and stressful workplace environment. Currently, more research is needed to understand the joint associations between sleep and pain and differences by work status and occupation type. This study examined the i...

Healthy life habits cannot be formed overnight; therefore, adherence to optimal sleep, physical activity, and healthy eating behaviors is vital. This paper examined the relationship between the adherence rate of the three key health behaviors (i.e., sleep, physical activity, and healthy diet) and cognitive function in adulthood. Data were retrieved...

Objectives. To examine whether workplace interventions to increase workplace flexibility and supervisor support and decrease work–family conflict can reduce cardiometabolic risk. Methods.

Engaging in a wide range of pleasant activities may provide mental health benefits, particularly for those genetically predisposed to depression. This study examined associations between pleasant activity variety, mental health, and genetic vulnerability in two U.S. cohort studies (N = 2,088). Participants reported depressive symptoms, mental healt...

Background Having multiple sleep problems is common in adulthood. Yet, most studies have assessed single sleep variables at one timepoint, potentially misinterpreting health consequences of co-occurring sleep problems that may change over time. We investigated the relationship between multidimensional sleep health across adulthood and mortality. M...

Background and Objectives Sleep disorders often predict or co-occur with cognitive decline. Yet, little is known how the relationship unfolds among older adults at risk for cognitive decline. To examine the associations of sleep disorders with cognitive decline in older adults with unimpaired cognition, or impaired cognition (mild cognitive impairm...

This study investigated stressors and strains, resources, and well-being among Black working caregivers (BWC) and White working caregivers (WWC) who participated in the Midlife in the United States study (Black: n = 49, White: n = 250). Comparisons were made between BWC and WWC for primary caregiving stressors, secondary strains, resources, and wel...

Participating in a broad and balanced range of daily activities (i.e., activity diversity) has been associated with better cognitive functioning in later life. One possible explanation for this finding is that high levels of activity diversity are merely a proxy for being more physically active, a factor robustly linked to cognitive health. The pre...

“Sleep health” is defined as positive attributes based on a number of sleep dimensions. Proposed by Buysee [1], the concept identified six specific sleep dimensions that are important for adult health and functioning: (1) regularity, (2) satisfaction, (3) alertness, (4) timing, (5) efficiency, and (6) duration (“Ru-SATED”). A paradigm shift for the...

Objective: This study examined whether social activity diversity, a novel concept indicating an active social lifestyle, is associated with lower subsequent loneliness, and decreased loneliness is further associated with less chronic pain over time. Methods: 2528 adults from the Midlife in the United States Study (Mage = 54 yrs) provided data at...

Purpose The COVID-19 pandemic may negatively impact the careers of U.S. women faculty in computer science (CS) – a field with few women and high attrition rates among women – due to difficulties balancing increased work and family demands (author citation). Thus, it is important to understand whether supervisors may help to decrease this work-to-li...

Work is closely intertwined with employees’ sleep quantity and quality, with consequences for well-being and productivity. Yet despite the conceptualization of sleep health as a multidimensional pattern of various sleep characteristics, little is known about workers’ experiences of the diverse range of sleep health dimensions (e.g., sleep regularit...

Work demands can undermine engagement in physical exercise, posing a threat to employee health and well-being. Integrating resource theories and a novel decision-making theory called the decision triangle, we propose that this effect may emerge because work stress changes the energetic and emotional processes people engage in when making decisions...

Introduction Caregivers often exhibit unhealthy/dampened cortisol profiles and sleep problems due to high stress. Grandparent caregivers (GP-CG) may be particularly vulnerable with caregiving burden and age-related changes in sleep/health. Yet there is lack of empirical evidence examining baseline cortisol and reactivity in GP-CG and how they are a...

Objectives: Lifespan perspectives have long acknowledged that individual functioning is shaped by historical and socio-cultural contexts. Secular increases favoring recent cohorts are widely documented. However, little is known about secular trends in day-to-day activities and whether historical changes have occurred in younger and older adults al...

Two separate bodies of literature point to the link between family bereavement and cardiovascular health and between sleep quality and cardiovascular outcomes. However, less is known about the joint influence of family bereavement and sleep quality on cardiovascular functioning. The aims of this study were to examine the relationships between exper...

Objectives It has been reported that job demands affect sleep, but how different levels of job demands affect sleep remains unclear. We examined whether curvilinear relationships exist between job demands and multiple sleep health outcomes. Design: Cross-sectional analyses with linear and quadratic effects, using self-administered survey data. Sett...

Decisions during adulthood set the foundation for healthy aging, but descriptions of healthy and unhealthy decision processes are missing. We extracted latent profiles of daily decision resources (energy and affect) and linked them to daily leisure activity. Diary data was collected from working adults (N=83; Mage=37 years) over the ten workdays (N...

Good sleep is necessary for healthy aging, but it may be threatened by work stress. This study connected midlife job characteristics to trajectories of sleep health profiles (within-person configurations of key self-reported facets: duration, regularity, sleep onset latency or SOL, insomnia symptoms, feeling unrested, and napping) over one decade....

This study investigated whether sleep quality mediates the relationship between race/SES and biomarkers (CRP, IL6, IL10, TNF-α). Participants in the Midlife in the United States Study (n=1,689; Mage=53.02) completed the Pittsburgh Sleep Quality Index and provided information on eight life-course indicators to measure SES. Black individuals and thos...

Older adults in the workforce face natural age-related decline that may impede their work performance. Sleep and cognitive function, both of which are degraded with age, may affect work performance in older workers. Workplace demands and support may also play roles in older workers’ performance. Yet there remains a lack of effort in identifying mod...

Negative consequences of sleep health problems are common in middle-age but poorly understood. This study investigated multidimensional sleep health in middle adulthood and mortality risk. Participants from the Midlife in the United States Study reported sleep characteristics in 2004-2006 (T1; n=9,640, Mage=52.72) and again in 2013-2016 (T2; n=4,33...

Leisure activities promote healthy aging, yet aging poses new challenges to engagement in active, meaningful, health-promoting leisure. This stalemate wherein people need to but struggle to engage in healthy leisure as they age calls for further research describing what healthy leisure entails, decision processes predicting it, and long-term conseq...

Sleep health during midlife sets the stage for health over the lifespan. Mindfulness, or present-moment awareness and attention, is shown to benefit sleep, yet mechanisms explaining these benefits are missing. Applying self-regulation theory, we test affective and cognitivemechanisms linking mindfulness to quantitative and qualitative sleep health....

Studies report that subjective and objective sleep parameters often do not agree with each other. This study examined if discordance between subjective and objective sleep measures are associated with cognition. Participants from the Midlife in the United States study (n=627) provided subjective (self-report) and objective (actigraphy) sleep durati...

Previous studies have established a connection between higher mindfulness and cognitive abilities; however, few studies have considered the mechanism underlying this relationship. The cognitive benefit of mindfulness may be through reduced fatigue and daytime sleepiness. This study examined if higher, naturally occurring mindfulness is associated w...

Objectives Activity diversity – an index of active lifestyles that captures variety (number) and evenness (consistency) in activity engagement – is known to support health in adulthood. However, less is known who has higher or lower activity diversity, information that helps identify individuals who may be at greater risk for poor health. This pape...

Objectives It has been reported that job demands affect sleep, but how different levels of job demands affect sleep remains unclear. We examined whether curvilinear relationships exist between job demands and multiple sleep health outcomes. Design Cross-sectional analyses with linear and quadratic effects, using self-administered survey data. Set...

Ecological momentary assessment (EMA) can capture how sleep, stress, and well-being are related within individuals. However, the use of EMA involves participant burden, which may be a major barrier when studying at-risk populations like frontline workers. To guide future research interested in using EMA, this study examined variance components in s...

Stress can elicit both positive and negative impacts on cognition. Less is known about whether and how daily stressors are associated with perceived cognitive performance in healthcare workers. We examined daily associations between stressors and perceived cognitive performance in nurses and whether these associations differed by age or nursing ten...

Objectives Although individual sleep characteristics are related to frailty, these characteristics do not occur separately. A multidimensional measure of sleep might provide a better estimation of frailty compared to isolated sleep characteristics. This study investigated the association of a multidimensional measure of sleep health with frailty bo...

In two studies, we examined preconditions of resource-building processes between family and work. Focusing on positive father-child interactions, we investigated positive mood states as links between the two life domains. Fathers employed in information technology (N 1 = 59) and the retail sector (N 2 = 75) participated in micro-longitudinal studie...

Introduction While sleep health is comprised of multiple dimensions, extant research tends to investigate single elements of sleep, such as sleep duration or sleep quality. The current study aimed to explore whether psychological and behavioral factors were associated with a multidimensional sleep health score as well as if sleep health was related...

Pileup of insufficient sleep was operationalized as the number of consecutive nights with <6 hours of...

Two separate bodies of literature point to the significant roles of sleep and stress and their associations with health outcomes in adulthood. To further extend the field’s knowledge on sleep, stress, and health, it is essential to consider the multi-dimensional aspects of sleep and diverse stress contexts and identify ways in which the three facto...

While previous studies evince a strong link between family bereavement and worse cardiovascular functioning, factors that may influence the association remain unexplored. This study examined the relation between experiencing the death of an immediate family member and heart rate variability (HRV) and whether the associations differed by sleep quali...

Recent studies indicate that engaging in more diverse activities is related to higher cognitive functioning. Questions remain, however, regarding whether activity variety within different domains is important. We examined how overall activity variety across domains, as well as variety within cognitive, physical, and social domains are related to co...

Active lifestyles are related to better cognitive health. More work is needed, however, to examine whether participating in a variety of daily activities (i.e., activity diversity) has unique importance beyond amount of activity. The current study examined associations between daily activity diversity and cognitive functioning among community-dwell...

Scheduling of pleasant activities is a core treatment component for various psychiatric disorders, but little is known about whether variety in positive experiences is associated with improved mental health and well-being. Here we demonstrate the benefits of diverse positive experiences. Using data from the Midlife in the United States (MIDUS) II (...

Although individual sleep characteristics are related to frailty, these characteristics do not occur separately. A multidimensional measure of sleep might provide a better estimation of frailty compared to isolated sleep characteristics. This study investigated the association of a multidimensional measure of sleep health with frailty and examined...

For middle-aged adults, achieving adequate sleep is a challenge but essential for long-term health. The present study identified latent sleep profiles to clarify how multiple sleep variables (i.e., regularity, satisfaction, alertness, timing, efficiency, and duration) cooccur within middle-aged adults and the implications these holistic sleep exper...

Despite the theory that dreams function to process emotions, few studies have examined how emotional experiences during daytime (“daytime affect”) are associated with the emotional tone of dreams (“dream affect”) that night, and vice versa. This study examined bidirectional associations between dream affect and daytime positive and negative affect....

The COVID-19 pandemic has created challenges and opportunities for research. This is especially true for research on essential workers, such as hospital nurses. In adaptation to the pandemic, the current study aimed to assess the feasibility and acceptability of a fully remote study to collect data on psychological and behavioral measures such as d...

We examined whether the diversity of daily activities (“activity diversity”) is associated with the diversity of daily emotions (“emodiversity”) and if the association differs by age. Two samples of adults from the Midlife in the United States Study provided activity and emotion data for eight days. Greater activity diversity was associated with gr...

The study examined the mediating role of subjective and perseverative cognition on sleep and work impairment. Sixty nurses completed a background survey and 14-days of ecological momentary assessments (EMA) and sleep actigraphy. Each day, participants evaluated their subjective cognition (mental sharpness, memory, processing speed), perseverative c...

Sleep is a modifiable determinant of health. It changes with advancing age and in response to diverse contexts (e.g., related to work or one’s health). Previous studies have often used single measures of sleep duration or sleep quality. However, a recent paradigmatic shift towards multidimensional sleep health emphasizes the importance of examining...

The COVID-19 pandemic dramatically changed the structure of our daily lives. One of the most significant changes is a limited opportunity to engage in face-to-face social interactions and enjoy diverse daily activities. This raises a public health concern, because diverse experiences are critical sources of health by increasing social integration,...

Unconstructive repetitive thoughts are indicative of rumination about daily experiences. Given that poor sleep is associated with greater reactivity to daily stressors, we examined joint associations of daily sleep and stress with daily rumination. 143 nurses completed 14 days of ecological momentary assessments (EMA; assessments of daily sleep, st...

Broad and even participation across daily activities (“activity diversity”) has been found to be associated with better health. Less is known about who has greater activity diversity. We examined whether personality traits are associated with activity diversity in two independent samples of adults. Data came from the Midlife in the United States St...

Prior studies have shown that parent and adolescent cortisol are associated across days and that this covariation may be adolescent-driven. This study extends this literature by (a) testing whether parents’ cognitive interference (i.e., distracting and ruminative thoughts potentially due to worry) mediates the linkages between adolescent and next-d...

Rationale Sleep health is best described by the co-occurrence of various dimensions (e.g., regularity, daytime alertness, satisfaction, efficiency, duration) but is rarely measured this way. Information is needed regarding common within-person patterns of sleep characteristics among adults and their relative healthiness. Objective To deepen unders...

Previous research shows that adults with children have poorer sleep overall than adults without children. Poorer sleep is associated with experiencing more frequent and severe stressors. The daily link between sleep and stressors may differ by parenting status; yet this potential difference has not been addressed, especially in nurses who provide c...

Background: Mandated social distancing practices and quarantines in response to COVID-19 have resulted in challenges for research on healthcare workers, such as hospital nurses.
