Abstract How older adults protect their cognitive health, reduce their risk for cognitive decline, and manage cognitive changes vary for men and women. To advance what is known about these differences and to promote inclusion of sexual and gender minorities in research, we are developing an empirically-informed research framework for studying gender effects in aging and Alzheimer’s research. In this presentation, we describe the framework informing our approach and present results from analyses of gender effects in The Health and Retirement Study that examine gender differences in the associations observed between education and cognitive measures in older adults. Our findings show gender’s effects on education vary in direction and magnitude as gender norms changed over time. Although college education serves as a factor protective against cognitive decline, characteristics of who achieves a four-year college degree change over time. We discuss the implications of our results for aging and Alzheimer’s disease research.

Abstract As the number of older adults increases, increased prevalence of cognitive and sensory impairments pose growing public health challenges. Research on the relationship between hearing impairment and cognition, however, is minimal and has yielded mixed results, with some studies finding that hearing impairment is associated with cognitive decline, and others reporting that the association is weak or non-existent. Most of this research has been conducted outside of the U.S., and the few U.S.-based longitudinal studies have relied mostly on small, non-representative samples involving short follow-up periods. Further, despite known gendered patterns in cognitive and hearing impairments, no studies to date have examined whether the relationship between the two varies by gender. Our study addresses these weaknesses in the literature by utilizing nine waves of the Health and Retirement Study (1998-2014; n=14,169), a large, nationally representative, longitudinal study that facilitates examination of long-term interrelationships between hearing and cognitive impairments. In this study, we use autoregressive latent trajectory (ALT) methods to model: 1) the relationship between hearing impairment and cognitive decline, and 2) sex differences in the relationship. ALT models enable us to determine whether hearing impairment and cognitive impairment are associated, net of their common tendency simply to co-trend with age. Results indicate that hearing and cognitive impairments are strongly interrelated processes that trend together over time. Moreover, hearing impairment has an increasing impact on cognitive impairment across age while the effect of cognitive impairment on hearing impairment levels out over time. Sex differences in these patterns are discussed.

Abstract Internet is increasingly popular among older adults and have changed interpersonal interactions. However, it remains controversial whether older people are more or less lonely with internet use. This paper tests the longitudinal association of internet use and loneliness among older people. One pathway that explains the association, the mediation effect of social contact, was examined. Data from the 2006, 2010 and 2014 waves of Health and Retirement Study was used. Hierarchical liner modeling results showed internet use was related to decreased loneliness over 12-year period of time (b=-0.044, p<.001). Internet use was associated with more social contact with family and friends overtime (b=0.261, p<.001), social contact was related to less perceived loneliness longitudinally (b=0.097, p<.001). The total effect of internet use on loneliness is -0.054 and the mediated effect is -0.025. The findings imply that online activities can be effective for reducing loneliness for older people through increased social contact.

Abstract Prior research has found that the risk of cognitive decline increases after the death of a spouse. In general, the impact of life transitions is contingent on contextual factors such as socio-demographic characteristics or relationship quality. However, there is limited research on how marital quality before spousal loss and gender influence the association between spousal loss and cognitive change. The current study examines the effects of spousal loss on change in cognitive functioning as well as the moderating effects of pre-loss marital quality and gender. Data from two waves of the Midlife in the United States (MIDUS) study were analyzed (MIDUS2: 2004-05, MIDUS3: 2013-14). The analytic sample consists of two groups: (1) 179 bereaved adults who were age 54 or older at MIDUS2 (M = 65.2, SD = 9.5) and whose spouses died between MIDUS2 and MIDUS3, and (2) 179 non-bereaved adults, matched with the bereaved group on age and gender, who did not experience spousal loss between the two waves. Cognitive function was assessed via BTACT (Brief Telephone Adult Cognition Test) at both waves. Regression results show that both pre-loss marital quality and gender significantly moderate the association between spousal loss and change in cognitive functioning. Specifically, relative to their counterparts, men and those who reported better marital relationships prior to spousal death had a greater risk of cognitive decline after a spouse’s death. The findings suggest the significance of pre-loss marital quality and gender for cognitive changes in widowhood and have implications for the development of efficient interventions

Abstract Fear of Falling (FOF) is common and associated with poor mobility in aging but whether persistence of FOF endorsement influences cognitive decline has not been reported. Here we determined the effect of FOF, measured dichotomously and after accounting for persistence, on decline in global cognitive function (GCF), memory, and attention/executive functions. Older adults with persistent FOF (n=81; mean age=77.63±6.67 yrs; %female=74.1), transient FOF (n=60; mean age=76.93±6.01 yrs; %female=61.7), and no FOF (n=286; mean age=75.77±6.42 yrs; %female=49.3) were included. FOF was assessed through yes/no responses to “do you have a fear of falling?” at baseline. GCF was assessed using RBANS; memory was assessed using a composite score comprising the immediate and delayed recall index scores from RBANS; attention/executive functions were assessed via a composite score comprising TMT A & B, letter and category fluency tasks, and digit symbol modalities. Cognitive measures were administered annually for up to six years. Linear mixed effects models revealed that persistent FOF was associated with a worse decline in GCF compared to both transient FOF (estimate=0.78, p=.022) and no FOF (estimate=0.75, p=.004). Persistent FOF was also associated with a worse decline in memory compared to those with transient FOF (estimate=0.08, p=.004) and those with no FOF (estimate=0.06, p=.006). Associations between FOF status and decline in attention/executive functions were not significant. These findings demonstrate that persistent FOF is a risk factor for cognitive decline in community-residing older adults.

BackgroundCognitive impairment and depression often co-occur in older adults, but it is not clear whether depression is a risk factor for cognitive decline, a psychological reaction to cognitive decline, or whether changes in depressive symptoms correlate with changes in cognitive performance over time. The co-morbid manifestation of depression and cognitive impairment may reflect either a causal effect or a common cause, depending on the specific symptoms experienced and the cognitive functions affected.MethodThe study sample comprised 1506 community-dwelling older adults aged ⩾65 years from the Longitudinal Aging Study Amsterdam (LASA). We conducted cross-domain latent growth curve analyses to examine longitudinal associations between late-life depression dimensions (i.e. depressed affect, positive affect, and somatic symptoms) and specific domains of cognitive functioning (i.e. processing speed, inductive reasoning, immediate recall, and delayed recall).ResultsPoorer delayed recall performance at baseline predicted a steeper increase in depressed affect over time. Steeper decline in processing speed correlated with a steeper increase in somatic symptoms of depression over time.ConclusionsOur findings suggest a prospective association between memory function and depressed affect, whereby older adults may experience an increase in depressed affect in reaction to poor memory function. Somatic symptoms of depression increased concurrently with declining processing speed, which may reflect common neurodegenerative processes. Our findings do not support the hypothesis that depression symptoms may be a risk factor for cognitive decline in the general population. These findings have potential implications for the treatment of late-life depression and for the prognosis of cognitive outcomes.

Background: Subjective cognitive decline (SCD) may be an early indicator of cognitive impairment, but depressive symptoms can confound this relationship. Associations may be influenced by differences between individuals (i.e., between-persons) or how each individual changes in their experiences over time (i.e., within-persons). Objective: We examined depressive symptoms as a mediator of the between- and within-person associations of SCD and objective memory in older adults. Methods: Coordinated analyses were conducted across four datasets drawn from large longitudinal studies. Samples (range: n = 1,889 to n = 15,841) included participants 65 years of age or older with no dementia at baseline. We used multilevel structural equation modeling to examine the mediation of SCD and objective memory through depressive symptoms, as well as direct relationships among SCD, objective memory, and depressive symptoms. Results: Older adults who were more likely to report SCD had lower objective memory on average (between-person associations), and depressive symptoms partially mediated this relationship in three of four datasets. However, changes in depressive symptoms did not mediate the relationship between reports of SCD and declines in objective memory in three of four datasets (within-person associations). Conclusion: Individual differences in depressive symptoms, and not changes in an individual’s depressive symptoms over time, partially explain the link between SCD and objective memory. Older adults with SCD and depressive symptoms may be at greater risk for poor cognitive outcomes. Future research should explore how perceived changes in memory affect other aspects of psychological well-being, and how these relationships influence cognitive decline and Alzheimer’s disease risk.

Abstract We examined the dual trajectories of subjective memory impairment (SMI) and objective cognitive decline and their associated factors in U.S. older adults. We used data from the Health and Retirement Study which includes a nationally representative sample of 19,408 Americans age 65 and older from 1998 to 2016. Trajectories of SMI and objective cognitive decline were simultaneously characterized using a group-based trajectory model and multinomial logistic regressions were used to assess factors associated with the dual-trajectory typologies. Four dual-trajectories were identified: “minimal SMI and stable-low cognitive decline” (33.1% of respondents); “minimal SMI with accelerated cognitive decline” (28.2%); “significant SMI with moderate cognitive decline” (21.0%); and “moderate SMI with steady cognitive decline” (17.6%). Being male, minority, low educated, living alone, and having comorbidities were associated with trajectories featuring greater SMI or more rapid deterioration in cognition. The results suggest complex co-occurring changes in subjective memory and objective cognition in older adults.

Purpose: To examine the effects of prayer and meditation on the episodic memory of older adults. Design: Secondary analysis of Health and Retirement Study (HRS). Method: Drawing from a subsample of HRS ( n = 1,135), this study utilized generalized estimating equation regression models to examine the effects of meditation and prayer on changes in episodic memory of older adults over time. Findings: Findings show a statistically significant positive effect of the use of prayer (0.50, p < .05) on episodic memory score at baseline. We also observed a slight gain in episodic memory over time for older adults who used prayer (0.04, p = .05). Meditation was not found to have a statistically significant effect on changes in memory in later life. Conclusion: This study illustrates the benefits of prayer in preserving memory and provides much needed empirical basis for community-level interventions to enhance memory in later life.
