Abstract To examine the prospective associations between total cholesterol (TC) variability and cognitive function in a large sample of Chinese participants aged 45 years and above. A total of 6,377 people who participated in the China Health and Retirement Longitudinal Study (CHARLS) were included. TC variability was defined as the intra-individual standard deviation over two blood tests in CHARLS 2011 and 2015 (Wave 1 and Wave 3). Cognitive function was assessed by a global cognition score, which included three tests: episodic memory, figure drawing and Telephone Interview of Cognitive Status (TICS). Multivariate linear regression models (MRLMs) and generalized estimating equation (GEE) were used to investigate associations between TC variability and cognitive scores. After adjusting for potential confounders, male participants with higher visit-to-visit TC variability showed lower global cognition scores (β = − 0.71, P < 0.001). After further adjustment for baseline cognition, the association remained statistically significant (β = − 0.68, P < 0.001). The domains with declines were focused on episodic memory (β = − 0.22, P = 0.026) and TICS (β = − 0.44, P = 0.004). However, these associations were not found in women (β = − 0.10, P = 0.623). For men, the rates of decline in global cognition increased by 0.14 (β = − 0.14, P = 0.009) units per year while TC variability increased by 1 mmol/L. For males, higher visit-to-visit TC variability correlated with lower cognitive function and an increased rate of decreases in memory. More attention should be paid to cognitive decline in males with high TC variability, and particularly, on decreases in memory, calculation, attention and orientation.

AbstractStudy objectivesRodent studies suggested that improvement in sleep duration might correlate with better cognitive function. We aimed to examine the associations between changes in sleep duration and cognitive function.Methods10325 individuals from the China Health and Retirement Longitudinal Study (CHARLS) were included. Self-reported nocturnal sleep duration and cognitive function were assessed in CHARLS 2011, 2013 and 2015 (Wave 1, Wave 2, Wave3). Cognitive function was assessed by a global cognition score, which included three domains: episodic memory, figure drawing and Telephone Interview of Cognitive Status (TICS). Generalized additive models (GAM) and Generalized estimation equations (GEE) were used to examine the associations between baseline sleep duration and longitudinal cognitive function. We used generalized linear models (GLM) to study the associations between changes in sleep duration and cognitive function in Wave 3.ResultsAfter adjusting for potential confounders, change from short sleep duration (SSD) to moderate sleep duration (MSD) was associated with better global cognition scores (β=0.54, P <0.01). Change from SSD to long sleep duration (LSD) (β=-0.94, P <0.001) or change from LSD to SSD (β=-1.38, P <0.01) was associated with lower global cognition. For individuals with MSD, ≥2 h increase (β=-0.89, P <0.001) or decrease (β=-0.70, P <0.001) in sleep duration was associated with lower global cognition.ConclusionsFor short sleepers, improvement in sleep duration correlated with better cognition. For long sleepers, there was no need to reduce sleep duration. Excessive changes or deviation from the moderate duration was associated with lower cognition.

The Relationship

Abstract Research has found relationships between experiencing stressful events and lower cognitive function in late life. However, there is little research about the cumulative experiences of significant historical events and cognitive function. Historical events may be unique compared to other life events due to their potential distal relationship to the individual. This study aims to examine the relationship between experiencing significant historical events and cognitive function among Chinese older adults. Data were drawn from the PINE Study, a cohort study of 3,126 US Chinese older adults collected from 2017-2019. Participants were asked if they experienced the Japanese invasion, famine, Great Leap Forward, Vietnam War, Cultural Revolution, and the Tian’anmen Square Protests. A composite score of 0-6 was calculated to count the number experienced. Cognitive function was measured through global cognition, episodic memory, working memory, processing speed, and Chinese MMSE. Linear and quantile regression were performed. Among the participants, 1908 (61.04%) were female with mean age of 75.33 (SD=8.22) years. The average number of historical events experienced was 2.36 (SD=1.44). After adjusting for covariates, every one additional historical event experience was associated with better global cognition (b=0.26, SE=0.009, p&lt;.01), episodic memory (b = 0.045, SE=0.012, p&lt;.001), and processing speed (b=0.383, SE=0.135, p&lt;.01). Number of historical events was not significantly associated with working memory or C-MMSE. The positive relationship between historical events and some cognitive domains suggests a potential resilience effect after experiencing historical events. Future research should examine whether participants found events stressful and whether there are differential relationships to cognitive function.

Abstract Nearly 3.5 million sexual and gender minority (SGM) adults aged 60+ in the U.S. identify as lesbian, gay, bisexual, transgender, and/or queer. We recruited over 50 diverse SGM older adults from the community to better understand correlates of their cognitive function. The Telephone Interview for Cognitive Status, an 11-item screening test of global cognition was used over the phone or in-person. We will describe relationships among cognition and several sociodemographic and health variables (age, sex assigned at birth, SGM identities, race/ethnicity, and health). Past research has highlighted higher rates of perceived memory problems among lesbian, bisexual and transgender adults compared to both gay men and heterosexual men and women. These rates were also higher among those who identify as women. We highlight implications for researching gender identity and cognition in late life, such as the influence of gender roles on cognition and the assessment of gender expression and related constructs.

Abstract Globally, around 1 in 6 older adults experienced some form of elder mistreatment in community settings. However, little is known about the prevalence of polyvictimization, or experience of multiple forms of abuse, which may exacerbate negative outcomes over that of any one form of victimization in isolation. Data were drawn from the PINE study. Polyvictimization was defined as exposure to multiple forms of victimization, including psychological, physical, and sexual mistreatment, financial exploitation, and caregiver neglect. Cognitive function was evaluated by global cognition, episodic memory, executive function, working memory, and MMSE. Regression analyses were performed. Among 3153 participants, 128 experienced two forms of abuse while 12 experienced three or more forms of abuse. Polyvictimization was associated with lower global cognition (b=-0.05, SE=0.02, p&lt;.05), episodic memory (b=-0.06, SE=0.03, p&lt;.05), working memory (b=-0.14, SE=0.07, p&lt;.05), and processing speed (b=-0.68, SE=0.33, p&lt;.05). Interventions could target older adults with polyvictimization and protect their cognitive function.

Abstract The study examined the association between cognitive function and Tai Chi practice among older Chinese Americans. Data from the Population Study of Chinese Elderly in Chicago (N=3,157) was analyzed by multivariate logistic regression. Cognitive function was assessed by global cognition, episodic memory, executive function, working memory, and Chinese Mini-Mental State Examination (C-MMSE). The results showed that cognitive function was significantly associated with Tai Chi practice. Participants with higher scores of global cognition (OR = 1.44, 95% CI: 1.20–1.73, p = 0.00), episodic memory (OR =1.27, 95% CI: 1.10–1.47, p = 0.00), executive function (OR = 1.017, 95% CI:1.00–1.03, p = 0.01), working memory (OR = 1.07, 95% CI: 1.02–1.12, p = 0.01), and C-MMSE (OR = 1.06, 95% CI: 1.03–1.09, p = 0.00) were more likely to practice Tai Chi. This study demonstrated that Tai Chi may benefit cognitive function in Chinese older adults.

Abstract The global growing rates of cognitive decline and dementia, together with the absence of curative therapies for these conditions, support the interest in researching potential primary prevention interventions, with particular focus on dietary habits. The aim was to assess the association between polyphenol intake and 6-year change in cognitive function in the ‘Seguimiento Universidad de Navarra’ (SUN) Project, a Spanish prospective cohort study. Changes (final – initial) in cognitive function were evaluated in a subsample of 806 participants (mean age 66 (sd 5) years, 69·7 % male) of the SUN Project using the validated Spanish Telephone Interview for Cognitive Status-modified score. Polyphenol intake was derived from a validated semi-quantitative FFQ and matching food composition data from the Phenol-Explorer database. Multivariable linear regression models were used to evaluate the association between total polyphenol intake, polyphenol subclasses and cognitive changes. No significant association between total polyphenol intake and changes in cognitive function was found. However, a higher intake of lignans (βQuintile (Q) 5 v. Q1 0·81; 95 % CI 0·12, 1·51; Ptrend = 0·020) and stilbenes (βQ5 v. Q1 0·82; 95 % CI 0·15, 1·49; Ptrend = 0·028) was associated with more favourable changes in cognitive function over time, particularly with respect to immediate memory and language domains. Olive oil and nuts were the major sources of variability in lignan intake, and wine in stilbene intake. The results suggest that lignan and stilbene intake was associated with improvements in cognitive function.

Background and Objectives:Evidence on the association of the cognitive reserve (CR) with the cognitive trajectories is limited. We aimed to examine the influence of CR indicator on domain-specific cognitive trajectories taking brain pathologies into account.Methods:Within the Rush Memory and Aging Project, 1,697 dementia-free participants (mean age: 79.6 years) were followed up to 21 years. CR indicator encompassing education, early-life, mid-life, and late-life cognitive activities, and late-life social activity was ascertained at baseline and categorized as tertiles (the lowest, middle, and highest). Global cognition, episodic memory, semantic memory, working memory, visuospatial ability, and perceptual speed were assessed annually with 19 tests, from which composite scores were derived. During the follow-up, 648 died and underwent autopsies to evaluate brain pathologies. Data were analyzed using linear mixed-effect models.Results:Among the participants, the score of the CR indicator ranged from -8.00 to 5.74 (mean: 0.00±2.23). In multi-adjusted mixed-effect models, compared to the lowest CR, the highest was related to a slower decline in global cognition (β=0.028, 95% confidence interval [CI]: 0.012 to 0.043), episodic memory (β=0.028, 95% CI: 0.010 to 0.047) and working memory (β=0.019, 95% CI: 0.005 to 0.033) during the follow-up. In brain pathological data analysis, the association of the highest CR with cognitive function changes remained significant among participants with high Alzheimer’s disease pathology or gross infarcts.Discussion:High CR indicator is associated with preserved global cognitive function, episodic memory, and working memory, even in the presence of brain pathologies. Our findings highlight the important role of high CR accumulation in the prevention of cognitive decline.

A broad literature has explored racial disparities in cognitive aging. Research incorporating sociocultural factors would provide a more comprehensive understanding of minority aging. This study aims to investigate the role of family typology in cognition among U.S. Chinese immigrants. Data were derived from the Population Study of Chinese Elderly in Chicago (PINE). Family typology included tight-knit, unobligated ambivalent, commanding conflicted, and detached typologies. Cognition was evaluated by global cognition, episodic memory, working memory, executive function, and mini-mental state examination (MMSE). Linear and quantile regressions were used. Older adults with detached and commanding conflicted typologies reported lower global cognition than those with unobligated ambivalent typology. Detached, commanding conflicted, and tight-knit typologies were associated with poorer performance in episodic memory, working memory and MMSE than unobligated ambivalent typology, respectively. Social service providers could be aware of multifaceted family relationships when developing interventions for cognitive function and understand family typology as a whole.

Abstract The majority of studies on traumatic life events focus on posttraumatic stress disorder and depression, while less is known whether the cumulative exposure to traumatic events over the life course will deteriorate cognitive function. This study aims to investigate the association between lifetime traumatic events and cognitive function in an immigrant population. The data were drawn from the Population Study of Chinese Elderly in Chicago (PINE). Face-to-face interviews were conducted with a sample of 3,126 U.S. Chinese older adults in 2017-2019. Twelve types of traumatic events were assessed: physical assault, residential fires, sexual assault, miscarriage, abortion, imprisonment, being falsely accused, divorce, death of a loved one, being robbed, experiencing cancer, and being homeless. Cognitive function was measured through global cognition, episodic memory, working memory, processing speed, and Mini-Mental State Examination (MMSE). Linear regression was performed. In our sample, the maximum traumatic events experienced by one participant are eight types. Older adults who experienced one additional personal event were associated with higher global cognition (b=0.101, SE=0.012), episodic memory (b=0.130, SE=0.016), working memory (b=0.151, SE=0.034), processing speed (b=1.709, SE=0.178), and MMSE (b=0.124, SE=0.057), while controlling for age, gender, income, and education. In contrast with earlier studies, we identified the positive relationships between traumatic events and cognition. Older adults who had prior experience with stressful life events could demonstrate an advantage over those without such an experience. Further studies could investigate how individuals would respond to stressful life events, and how their resilience mechanism would promote cognitive function.

Introduction: To learn the trajectories of cognitive function before and after stroke among Chinese participants. Method: During the seven-year follow-up, 401 participants survived incident stroke and 7551 remained stroke free. Cognitive function was assessed by a global cognition score, which included episodic memory, visuospatial abilities, and executive function. A linear mixed model was developed to explore the repeated measurements. Result: There was no significant difference between the rate of pre-stroke cognitive decline and the decline rate of cognition among stroke-free participants. Among the stroke survivors, the acute decline was -0.123 and -0.187 SD/y in cognitive domains of episodic memory and visuospatial ability, respectively. Executive function did not decline acutely after stroke. In the years after stroke, the decline rate of global cognition was 0.074 SD/y faster than the rate before stroke. The additional decline rate of episodic memory and executive function was 0.043 and 0.061 SD/y, respectively. The rate of visuospatial ability did not change after stroke. Conclusion: Among Chinese stroke survivors, incident stroke was associated with acute decline in episodic memory and visuospatial abilities, and accelerated decline in episodic memory, orientation, attention, and calculation. Cognitive training may help alleviate post-stroke cognitive impairment.
