Associations of Daily Sleep and Stress With Rumination: An Ecological Momentary Assessment and Actigraphy Study

Abstract 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, stress, and rumination) and actigraphy. After controlling for age, sex, education, income, inpatient vs. outpatient nurse, workday, and day vs. night shift, there were significant joint associations of sleep and stress with daily rumination. Daily rumination was lowest when lower (-1SD) stressor severity or stressor frequency were paired with longer (+1SD) EMA or actigraphy sleep duration. Daily rumination was highest when higher stressor frequency was paired with higher actigraphy wake after sleep onset (i.e., poorer sleep quality). Future studies should assess whether rumination about daily experiences is associated with quality of patient care provided by nurses in a hospital setting.

Pennsylvania State University,University Park,Pennsylvania,United States 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 quality.The sample included respondents from the Midlife in the United States (MIDUS) Biomarker Project who reported losing an immediate family member -parents, spouse, siblings, or children -within a year before project (n = 94) and those who did not experience any deaths (n = 872).Results showed that the death of a family member was associated with worse HRV only among those who reported having a poor sleep quality and not for those with good sleep quality.These findings suggest that poor sleep quality may indicate psychophysiological vulnerability for those who experienced the death of an immediate family member.

DAILY STRESS AND SLEEP ASSOCIATIONS VARY BY WORK SCHEDULE: A BETWEEN-AND WITHIN-PERSON ANALYSIS IN NURSES


SUBJECTIVE AND PERSEVERATIVE COGNITION MEDIATE THE RELATIONSHIP BETWEEN SLEEP AND WORK IMPAIRMENT

Christina Mu, Brent Small, and Soomi Lee, University of South Florida, Tampa, Florida, United States

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 cognition (rumination) and work impairment (how much did you cut back on normal paid work, how much did the quality of your work suffer).Multiple sleep characteristics were measured by EMA and actigraphy.Multilevel mediation models adjusted for sociodemographics and work shift.At the between-person and within-person levels, there were mediated associations of sleep quality and sufficiency (but not actigraphy-measured sleep) with work impairment through subjective and perseverative cognition.Better sleep quality or higher sleep sufficiency were associated with better subjective and perseverative cognition, which, in turn, were associated with less work impairment.

Georgia Institute of technology, Atlanta, Georgia, United States Individuals with Mild Cognitive Impairment (MCI) face many challenges, including cognitive declines and reduced independence which are associated with poor health outcomes.Although there is no cure for MCI, mind-body exercise classes may improve cognitive function and reduce risk of falls (Wayne, Yeh, & Mehta, 2018).However, such classes are often not accessible for individuals with MCI due to lack of transportation, fear of being stigmatized, or inability to find instructors who have experience working with individuals with MCI (Hobson & Middleton, 2008;Rimmer, 2005).Tele-technology, such as video-conferencing software, has the potential to remove barriers to participation by allowing individuals to attend classes from home.The goal of this study was to assess the feasibility of using tele-technology to deliver mind-body classes to individuals with MCI.We evaluated technology acceptance and usability for OneClick.chat,a web-based video-conferencing platform designed for older adults.Stakeholders (4 subject matter experts, 2 individuals with MCI, and 2 care partners) participated in a user study that included questionnaires and a short interview.The technology acceptance data indicate that OneClick.chatwas perceived as easy to use.Some individuals expressed privacy and security concerns which could be addressed with additional education and support.These findings have implications for interface design, education, and training for deployment of tele-technology delivered mind-body classes for those with MCI.Previous research suggests a decline in body mass index (BMI) among older adults is associated with negative health outcomes, including mild cognitive impairment (MCI) and incident dementia (Gao et al., 2011).However, few studies have examined BMI longitudinal trajectories and how they change after MCI diagnosis among older African Americans.To characterize trajectories of change in BMI among older African American participants with no cognitive impairment at baseline we used data from the Minority Aging Research Study, MARS (N=408, 76.5% women, mean age = 73.5, mean education = 15.0).We constructed piecewise linear mixed-effects models that included a random intercept and two random slopes.The first slope began at baseline.The
