Objectives Heterogeneity among Black adults' experiences of discrimination and education quality independently influence cognitive function and sleep, and may also influence the extent to which sleep is related to cognitive function. We investigated the effect of discrimination on the relationship between objective sleep characteristics and cognitive function in older Black adults with varying education quality. Method Cross-sectional analyses include Black participants in the Einstein Aging Study (N  = 104, mean age = 77.2 years, 21% males). Sleep measures were calculated from wrist actigraphy (15.4 ± 1.3 days). Mean ambulatory cognitive function (i.e. spatial working memory, processing speed/visual attention, and short-term memory binding) was assessed with validated smartphone-based cognitive tests (6 daily). A modified Williams Everyday Discrimination Scale measured discriminatory experiences. Linear regression, stratified by reading literacy (an indicator of education quality), was conducted to investigate whether discrimination moderated associations between sleep and ambulatory cognitive function for individuals with varying reading literacy levels. Models controlled for age, income, sleep-disordered breathing, and sex assigned at birth. Results Higher reading literacy was associated with better cognitive performance. For participants with both lower reading literacy and more discriminatory experiences, longer mean sleep time was associated with slower processing speed, and lower sleep quality was associated with worse working memory. Later sleep midpoint and longer nighttime sleep were associated with worse spatial working memory for participants with low reading literacy, independent of their discriminatory experiences. Discussion Sociocultural factors (i.e. discrimination and education quality) can further explain the association between sleep and cognitive functioning and cognitive impairment risk among older Black adults.

Objectives This study explored the association between place-based characteristics (e.g. neighborhood socioeconomic deprivation) and physical health within older Black adults, a critical gap in the literature as identified by the National Institute on Minority Health and Health Disparities. Methods The sample was from Wave 1 data of Baltimore Study of Black Aging: Patterns of Cognitive Aging (N = 450; M age = 68.34). Variables included the area deprivation index (ADI), objective (e.g. average blood pressure) and subjective (e.g. self-rated health) measures of physical health. Multiple linear regression models were conducted controlling for key sociodemographic characteristics. Results Participants reporting better self-rated health and less likely to need help with activities of daily living were significantly more likely to be living in more disadvantaged neighborhoods based on national and state ADI, respectively, even after adjusting for covariates. A significant age and ADI interaction revealed better self-rated health was associated with a more disadvantaged neighborhood particularly for individuals ≤66 years. There was no significant association between ADI and objective physical health measures. Discussion The findings suggest that national- and state-level place-based characteristics should be considered along with individual-level factors, which can enrich the scientific understanding of how neighborhood characteristics relate to varying health indicators among older Black adults.

This preliminary study explored the correlates of leisure interests and constraints among 39 adult public housing residents from North Carolina and Pennsylvania. Most preferred activities included walking, volunteering, reading, cards, dining out, travel, movies, and music. Pearson and Spearman correlations revealed significant associations between education quality and leisure interests. Education quantity and quality, pain severity and interference, loneliness, and depressive symptoms were significantly associated with leisure constraints. With the growing number of adults depending upon public housing, it is imperative to understand leisure interests and constraints within these communities, to ensure the availability of appropriate community programs and services.

Objective The objective of this study was to examine satisfaction, test anxiety, and performance using computer-based cognitive batteries versus a paper-and-pencil neuropsychological battery among older Blacks. Method Self-identified Black adults (n = 87, age range: 55–86; mean education = 14) completed two computer-based tests (CogState and Joggle) and a paper-and-pencil neuropsychological battery. After each battery, participants reported their testing anxiety and satisfaction using the batteries. Descriptive, correlational, and regression analyses compared satisfaction, anxiety, and performance across the batteries. Results Majority of the participants reported more satisfaction with the computer-based (Joggle: 66%; CogState: 77%) than the neuropsychological (52%) battery. Participants also reported less testing anxiety after completing the computer-based batteries than the neuropsychological battery, F (2, 172) = 22.96, p <.001. Older adults' familiarity and comfort level with the computer were not associated with their performance on the computer-based tests (p >.05). Although testing anxiety was not associated with performance across the batteries, age and education quality were uniquely associated with performance on the CogState and neuropsychological batteries. Conclusions Computer-based cognitive batteries appear to be less intimidating than the commonly used paper-and-pencil neuropsychological tests for Black adults. Thus, these cognitive batteries may be useful tools for monitoring older Blacks' cognitive status. [ABSTRACT FROM AUTHOR]

Background: There is growing evidence that five-factor model personality traits are associated with self-reported sleep. We test whether these associations extend to objective sleep measures in older adulthood and whether measures of objective sleep mediate the relation between personality and subjective sleep. Methods: A random subsample of participants in the National Social Life and Aging Project (NSHAP) wore an accelerometer for up to three nights and had information on FFM personality traits (N = 620). Participants also reported on their feelings of being rested. Results: Higher neuroticism and lower extraversion and conscientiousness were associated with more frequent wake after sleep onset, greater fragmentation, and feeling less rested. Concurrent body mass index, disease burden, perceived stress, and depressive symptoms accounted for these associations. Personality was unrelated to total time spent asleep but conscientiousness was associated with earlier and more consistent bedtimes. None of the objective sleep metrics mediated the relation between personality and subjective sleep. Conclusions: The present research indicates that the associations typically found for personality and subjective sleep extend to objective sleep fragmentation. These objective measures, however, do not account for the relation between personality and feeling rested. [ABSTRACT FROM AUTHOR]

Objective The purpose of the current study is to examine the association between subjective memory complaints and sleep (quantity and quality) in African American older adults. Method Participants from the Baltimore Study of Black Aging (BSBA; n = 351; mean age = 71.99) completed a self-report sleep scale, subjective memory complaint scale, global cognitive status measure, and demographic questionnaire. Results Worse overall sleep quality was significantly associated with subjective reports of difficulty recalling the placement of objects, recalling specific facts from reading materials, and worse memory currently compared to the past. Specific sleep parameters (e.g. longer sleep latency and shorter sleep duration) were associated with negative appraisals of participants' ability to do specific tasks involving memory (e.g. difficulty recalling placement of objects). Participants classified as poor sleepers (Pittsburgh Sleep Quality Index [PSQI] total score > 5) were more likely to report worse memory now compared to the past than participants classified as good sleepers (PSQI total score ≤ 5). Conclusions Evaluation of sleep may be warranted when older adults, particularly African Americans, communicate concerns regarding their memory. Insufficient sleep may be a useful marker of acute daytime dysfunction and, perhaps, cognitive decline. Given memory problems are the hallmark of dementia, our findings support further evaluation of whether poor sleep can aid in the diagnosis of cognitive impairment. [ABSTRACT FROM AUTHOR]

This study examined the relationship between elders' cognitive performance and self-reported trouble falling asleep. Analyses were conducted on 174 older independently living, community dwelling African Americans (M age = 72.74; range = 65 to 90). Cognitive performance was measured using the Mini-Mental State Examination, Forward Digit Span task, Backward Digit Span task, Alpha Span task, and California Verbal Learning Test. Results suggested that individuals who reported trouble falling asleep tended to perform significantly worse than individuals who did not report trouble falling asleep on measures tapping short-term memory and working memory after controlling for age, education, gender, depression, and current health. These results demonstrate that a self-report of sleep difficulty may be a unique predictor of cognitive performance. [ABSTRACT FROM AUTHOR]
