Abstract BackgroundCognitive ability is an important measure of intrinsic capacity. In this study, we examine the association of life course socioeconomic status (SES) and height on cognitive functioning among older adults aged 50 and above for the two middle-income countries of India and China. We further assess the age pattern of cognitive decline with measures of life course socioeconomic status. MethodsCross-sectional comparative analysis was conducted using the WHO’s Study on global AGEing and adult health (SAGE) data for India and China. Multilevel mixed-effect regression analysis was used to predict the association of life course socioeconomic status, height with cognitive functioning. ResultsIn India and China, better childhood socioeconomic status measured as parental education is positively associated with cognitive functioning. The association between adult socioeconomic status and cognitive functioning was positive and highly significant. Height was significantly associated with improved cognitive functioning for India and China. Furthermore, the age-related cognitive decline was faster among older adults whose parents had no schooling, particularly the association between mother’s education and cognitive functioning is stronger in China. The cognitive decline is much faster among less-educated older adults than those with 10+ years of schooling in China. Wealthier older adults in India had higher cognitive functioning in middle age, however, wealth differences narrowed in older ages, suggesting the convergence of cognitive functioning by economic status at older ages. ConclusionsThe results of this study suggest a significant long-term impact of childhood conditions on later-life cognitive functioning in middle-income settings.

The population of older adults is rapidly increasing, as is the number and type of products and interventions proposed to prevent or reduce the risk of age-related cognitive decline. Advocacy and prevention are part of the American Speech-Language-Hearing Association’s (ASHA’s) scope of practice documents, and speech-language pathologists must have basic awareness of the evidence contributing to healthy cognitive aging. In this article, we provide a brief overview outlining the evidence on activity engagement and its effects on cognition in older adults. We explore the current evidence around the activities of eating and drinking with a discussion on the potential benefits of omega-3 fatty acids, polyphenols, alcohol, and coffee. We investigate the evidence on the hypothesized neuroprotective effects of social activity, the evidence on computerized cognitive training, and the emerging behavioral and neuroimaging evidence on physical activity. We conclude that actively aging using a combination of several strategies may be our best line of defense against cognitive decline.

Abstract LGBTQ older adults are at significantly increased risk for poor mental and physical health, likely consequential to lifelong bias. Allostatic load (AL), the net effect of “wear and tear” on the body resulting from repeated, chronic over-activation of the psychophysiological stress response system. Utilizing the Health Equity Promotion Model, the aim of this study was to test potential life course predictors of AL, including interpersonal violence, legal marriage, and identity management in a sample of LGBTQ adults 50 to 97 years of age (n=317). Results from a series of hierarchical linear regression models showed that adult physical abuse and late identity disclosure for those who had been in an opposite-sex marriage predicted higher AL in this sample of LGBTQ older adults, indicating need for increased research on bias over the life course as contributory to AL and biopsychosocial dysfunction among LGBTQ older adults.

Abstract Background Despite the aging HIV epidemic, increasing age can be associated with hesitancy to test. Addressing this gap is a critical policy concern and highlights the urgent need to identify the underlying factors, to improve knowledge of HIV-related risks as well as uptake of HIV testing and prevention services, in midlife-older adults. Methods We conducted five focus group discussions and 12 in-depth interviews between April 2013 and November 2016 among rural and urban Malawian midlife-older (≥30 years) men and women. Using a life-course theoretical framework we explored how age is enacted socially and its implications on HIV testing and sexual risk behaviours. We also explore the potential for HIV self-testing (HIVST) to be part of a broader strategy for engaging midlife-older adults in HIV testing, prevention and care. Thematic analysis was used to identify recurrent themes and variations. Results Midlife-older adults (30–74 years of age) associated their age with respectability and identified HIV as “a disease of youth” that would not affect them, with age protecting them against infidelity and sexual risk-taking. HIV testing was felt to be stigmatizing, challenging age norms, threatening social status, and implying “lack of wisdom”. These norms drove self-testing preferences at home or other locations deemed age and gender appropriate. Awareness of the potential for long-standing undiagnosed HIV to be carried forward from past relationships was minimal, as was understanding of treatment-as-prevention. These norms led to HIV testing being perceived as a threat to status by older adults, contributing to low levels of recent HIV testing compared to younger adults. Conclusions Characteristics associated with age-gender norms and social position encourage self-testing but drive poor HIV-risk perception and unacceptability of conventional HIV testing in midlife-older adults. There is an urgent need to provide targeted messages and services more appropriate to midlife-older adults in sub-Saharan Africa. HIVST which has often been highlighted as a tool for reaching young people, may be a valuable tool for engaging midlife-older age groups who may not otherwise test.

Abstract Background Social isolation and loneliness have each been associated with cognitive decline, but most previous research is limited to Western populations. This study examined the relationships of social isolation and loneliness on cognitive function among Chinese older adults. Methods This study used two waves of data (2011 and 2015) from the China Health and Retirement Longitudinal Study and analyses were restricted to those respondents aged 50 and older. Social isolation, loneliness, and cognitive function were measured at baseline. Follow-up measures on cognitive function were obtained for 7761 participants (mean age = 60.97, s.d. = 7.31; male, 50.8%). Lagged dependent variable models adjusted for confounding factors were used to evaluate the association between baseline isolation, loneliness, and cognitive function at follow-up. Results Loneliness was significantly associated with the cognitive decline at follow-up (episodic memory: β = −0.03, p < 0.01; mental status: β = −0.03, p < 0.01) in the partially adjusted models. These associations became insignificant after additional confounding variables (chronic diseases, health behaviors, disabilities, and depressive symptoms) were taken into account (all p > 0.05). By contrast, social isolation was significantly associated with decreases in all cognitive function measures at follow-up (episodic memory: β = −0.05, p < 0.001; mental status: β = −0.03, p < 0.01) even after controlling for loneliness and all confounding variables. Conclusions Social isolation is associated with cognitive decline in Chinese older adults, and the relationships are independent of loneliness. These findings expand our knowledge about the links between social relationships and the cognitive function in non-Western populations.

Older adults diagnosed with schizophrenia (OADWS) often enter long-term care facilities with unique challenges related to trauma and stress experienced throughout their life course. Health care workers often report that when they work with this population, they feel unprepared due to limited training. In this article, life course theory is presented as a lens for holistic nursing research and as a way for nurses to adapt interventions already used with cognitively impaired older adults (e.g., those diagnosed with Alzheimer's disease) for OADWS in long-term care. It is hoped that these ideas will facilitate discussion of ways to inform training for holistic long-term care of OADWS. Holistic principles of nursing addressed with life course theory as a lens include the following: (a) accounting for strengths and challenges; (b) honoring experiences, values, and health beliefs; (c) viewing interrelationships with the environment; and (d) nurturing of peace, wholeness, and healing.

Abstract Although cognitive training in healthy older adults (OA) has been controversial, specific and isolated cognitive skills such as semantic memory can be improved with appropriate designs. Semantic memory has been considered as a clinical marker for cognitive decline in dementia. The current study, as part of a larger touch-screen dual-language intervention program with cognitive training tools, aims to slow down the rate of cognitive decline in OA with dementia (OwD). A set of neuropsychological tests was conducted before and after the training program. After 24 training sessions over 8-12 weeks, OwD (11 females, 1 male, mean=85.8yo) improved significantly in their verbal working memory (Rey Auditory Verbal Learning Test; RAVLT) while performance of the cognitive-healthy OA (5 females, 3 males, mean=76.3yo) remained the same post-intervention. Our findings suggest that touch-screen technology can help OwD improve their semantic memory. The strengths and limitations of our game design and intervention will be discussed.
