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.

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]

Existing disparities regarding Black Americans' psychological health warrant further investigation of socioecological factors that may be associated with negative and positive dimensions of psychological health in this population. Romantic relationship functioning and neighborhood context are two domains relevant to Black Americans' mental health. However, less is known about how they may serve as independent and interactive prospective predictors of Black Americans' psychological health and potentially in distinctive ways for Black men and women. Using data from 333 partnered Black Americans who participated in the Midlife in the United States study, we investigated relationship adjustment and neighborhood quality as independent and interactive predictors of negative and positive affect 10 years later and examined gender differences in these linkages. Higher neighborhood quality predicted lower levels of negative affect and higher levels of positive affect for both men and women a decade later. Additionally, for Black men, the longitudinal association between relationship adjustment and negative affect differed by neighborhood quality such that better relationship adjustment predicted higher subsequent negative affect only for men in lower quality neighborhoods. Findings demonstrate the connections among romantic relationship functioning, ecological resources, and gender in this population and highlight the importance of incorporating socioecological and intersectional perspectives for predicting Black Americans' long-term psychological health. General Scientific Summary: This study suggests that living in higher quality neighborhoods is related to greater positive aspects and lower negative aspects of psychological health over time for Black Americans. Moreover, for Black men specifically, better romantic relationship functioning is connected to poorer psychological health when they reside in lower quality neighborhoods. [ABSTRACT FROM AUTHOR]

Objectives This study examined engagement levels across various domains of leisure activities in community-dwelling Black adults (age range = 50–80 years) and variability in daily leisure activity engagement and positive affect (PA; positive emotions or mood) and negative affect (NA; negative emotions or mood). Additionally, we explored whether PA and NA were associated with leisure activity engagement and whether these associations varied by sociodemographics. Methods Fifty adults (78% women; mean education = 11.62 years, standard deviation = 2.4) reported affect and leisure activity engagement over 8 occasions (2–3 weeks). Results Participants averaged 3 leisure activities/day with more engagement in watching television (news), walking, reading, and visiting others. Multilevel models identified significant within-person variation across domains of leisure activity engagement. A significant main effect was observed between daily NA and reduced social activity engagement. A significant interaction between NA and education was further illustrated on those occasions when NA was higher than usual, social and total leisure activity engagement tended to be lower, particularly for adults with ≤10 years of education. A significant interaction between NA and education was observed for entertainment activities. However, results indicated adults with ≥14 years of education, and a mean NA above the sample average, tended to engage in more entertainment activities. Finally, a significant interaction between PA and age was observed indicating adults aged ≥73 had a greater social engagement, particularly when daily PA was heightened. Discussion Results demonstrate within-person changes in the types of leisure engagement among Black adults. Potential factors related to these changes may result from interconnections between affect and demographic factors (age and education). [ABSTRACT FROM AUTHOR]

This study examined the within-person relationship between sleep and cognitive functioning. Fifty community-dwelling African Americans (age range 50-80 years) were asked to report their sleep duration and quality the previous evening and to complete cognitive measures over 8 occasions within a 2-3 week period. A within-person daily change in sleep duration was significantly associated with worse global cognitive performance. The greater an individual deviated away from his or her average sleep duration on a particular day, the more likely his or her performance would decline. These results demonstrate that the sleep-cognition relationship can be observed at a within-person level of analysis. [ABSTRACT FROM AUTHOR]

Objectives To examine the frequency of Mild Cognitive Impairment (MCI) in African American older adults. The study also plans to explore the specific cognitive domains of impairment as well as whether there are differences in demographics, health, and cognitive performance between MCI and normal participants. Design Cross-sectional. Setting Independent-living sample of urban dwelling elders in Baltimore, Maryland. Participants The sample consisted of 554 subjects ranging in age from 50 to 95 (Mean = 68.79 ± 9.60). Measurements Socio-demographics and health were assessed. Several cognitive measures were administered to assess inductive reasoning, declarative memory, perceptual speed, working memory, executive functioning, language and global cognitive functioning. Results Approximately 22% of participants were considered MCI (i.e. 18% non-amnestic vs. 4% amnestic). A majority of the non-amnestic MCI participants had impairment in one cognitive domain, particularly language and executive function. Individuals classified as non-amnestic MCI were significantly older and had more years of education than normal individuals. The MCI groups were not significantly different than cognitively normal individuals on health factors. Individuals classified as MCI performed significantly worse on global cognitive measures as well as across specific cognitive domains than cognitively normal individuals. Conclusion This study demonstrates that impairment in a non-memory domain may be an early indicator of cognitive impairment, particularly among African Americans.

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]

This study examined the fluid-crystallized distinction of cognitive abilities in African Americans. We analyzed the factorial invariance of a battery of cognitive ability measures in a sample of 197 community-dwelling African American elders. Specifically, factorial invariance was tested in groups of African American elders differing in age (50-61 years, 62-79 years) and education (low, high). Using a partial invariance approach, if non-invariance was found between two groups, we explored the specific model parameters that contributed to the overall lack of invariance. The results indicated that the factor structure was confirmed in the sample as a whole. Evidence of strict invariance was found between age groups. However, a lack of invariance of specific factor loadings, intercepts, and uniqueness terms was found between education groups. The importance of highlighting idiosyncrasies in cognitive performance among African Americans is shown using a within group variation approach. [ABSTRACT FROM AUTHOR]

The structure and organization of cognitive abilities has been examined across the life span. The current analysis had three specific aims: (1) test the factor structure of a broad cognitive ability battery across three age groups; (2) examine differences in the pattern of factor covariation across age groups; and (3) examine the pattern of factor mean differences across age groups. A sample of 512 older African Americans (mean age = 66.6 years, 25.4% male) from the Baltimore Study of Black Aging was administered a battery of cognitive tests assessing the domains of perceptual speed, verbal memory, inductive reasoning, vocabulary, and working memory. Factor models were estimated separately in middle-age adults (50–59 years, n = 107), young-old adults (60–69 years, n = 198), and old-old adults (70–79 years, n = 207). There was loading invariance across the three age groups that suggests that the selected tests measured cognition similarly across age. There was no evidence of dedifferentiation across increasingly older age groups. Factor mean differences were observed with the middle-age group having significantly higher factor means than the young-old and old-old groups; however, there was only one factor mean difference between the young-old and the old-old groups. The results suggest that a pattern of dedifferentiation of cognitive abilities does not exist within this sample of older African Americans and that the 60–69 year age range may be a critical period for cognitive decline in this population.
