Abstract Reduced energy is a hallmark feature of aging. Maintaining higher energy late in life may be a key adaptive strategy to the challenges that accompany older age and ultimately promote resilience. Perceived lack of energy is often construed as synonymous with fatigue, and energy and fatigue are frequently considered opposite aspects of the same phenomenon. However, evidence suggests that energy and fatigue have distinct underlying neurobiology. Further exploration of the energy/fatigue dichotomy is needed in community-dwelling older adults free of neuropathologies and clinically overt conditions. This symposium will first present clinical and epidemiologic justifications for operationalizing energy as a separate construct from fatigue and then will provide evidence on the underlying neurobiological correlates. Taken together, our results suggest perceived energy: a) overlaps with but is distinct from lower fatigability (Katz); b) may signal resilience against age-related declining mood and gait speed despite self-reported tiredness (Ehrenkranz); c) appear negatively influenced by Alzheimer’s neuropathology (Dougherty); and d) may reflect a distinct spatial distribution of brain functional connectivity (Hengenius). Thus, this symposium will explore energy as a mechanism related to yet distinct from fatigue and its implications for both healthy aging and neuropathological processes.

AbstractObjectiveTo explore influences on diet in a group of community-dwelling older adults in the UK.DesignData were collected through focus group discussions with older people; discussions were audio-recorded, transcribed verbatim and transcripts analysed thematically.SettingHertfordshire, UK.SubjectsParticipants were sampled purposively from the Hertfordshire Cohort Study, focusing on those whose diets had been assessed at two time points: 1998–2001 and 2011.ResultsNinety-two adults participated (47 % women; 74–83 years) and eleven focus groups were held. A number of age-related factors were identified that were linked to food choices, including lifelong food experiences, retirement, bereavement and medical conditions, as well as environmental factors (such as transport). There appeared to be variability in how individuals responded to these influences, indicating that other underlying factors may mediate the effects of age-related factors on diet. Discussions about ‘keeping going’, being motivated to ‘not give up’, not wanting to be perceived as ‘old’, as well as examples of resilience and coping strategies, suggest the importance of mediating psychological factors. In addition, discussion about social activities and isolation, community spirit and loneliness, indicated the importance of social engagement as an influence on diet.ConclusionsInterventions to promote healthier diets in older age should take account of underlying psychological and social factors that influence diet, which may mediate the effects of age-related factors.

Abstract BackgroundDigital health technologies are being increasingly developed with the aim of allowing older adults to maintain functional independence throughout the old age, a process known as healthy ageing. Such digital health technologies for healthy ageing are expected to mitigate the socio-economic effects of population ageing and improve the quality of life of older people. However, little is known regarding the views and needs of older people regarding these technologies. AimThe aim of this study is to explore the views, needs and perceptions of community-dwelling older adults regarding the use of digital health technologies for healthy ageing. MethodFace-to-face, in-depth qualitative interviews were conducted with community-dwelling older adults (median age 79.6 years). The interview process involved both abstract reflections and practical demonstrations. The interviews were transcribed verbatim and analyzed according to inductive content analysis. ResultsThree main themes and twelve sub-themes emerged. The three main themes revolved around the following thematic areas: favorable views and perceptions on technology-assisted living, usability evaluations and ethical considerations. ConclusionsOur study reveals a generally positive attitude towards digital health technologies as participants believed digital tools could positively contribute to improving their overall wellbeing, especially if designed in a patient-centered manner. Safety concerns and ethical issues related to privacy, empowerment and lack of human contact also emerged as key considerations.

Abstract This symposium addresses the role of vaccination to promote healthy aging, the process of developing and maintaining the functional ability that enables wellbeing in older age. Life-span immunization of adults across all age categories can help to reduce morbidity and mortality. Healthy aging is critical for our global society to counter the surge in healthcare costs that is coming as a result of the demographic shift to older age. Immune system function and response to vaccination declines with advancing age. Generating effective immune responses against new infectious disease targets can be difficult in older individuals. Important progress has been made in understanding the mechanisms underlying immunosenescence, the age-related decline of the immune response to infections and vaccinations. Innovative research and the development of new technologies, such as adjuvants, substances that can enhance and shape the immune response to the target antigen(s), has facilitated the development of vaccines specially tailored for adults. This evidence-based approach to the development of innovative vaccines addressing immunosenescence is an important clinically relevant healthy aging strategy to promote health throughout life.

Background and objective: Both low and high body mass index (BMI) have been associated with greater mortality in older adults. This study evaluated the trajectory of BMI in the final years of life. Design: Population-based cohort study. Setting: Community-dwelling adults in the English Longitudinal Study of Ageing between 1998 and 2012. Measurements: Body mass index, years before death and all-cause mortality. Analyses were adjusted for age, gender, educational level, housing tenure and social class. Results: Data were analysed for 16,924 participants with 31,857 BMI records; mean age at study start, 61.6 (SD 10.9) years; mean BMI, 27.5 (4.7) Kg/m2. There were 3,686 participants (4,794 BMI records) who died and 13,238 participants (27,063 BMI records) who were alive at last follow-up. Mean BMI increased with age to 60-69 years but then declined, but the age-related decline was more rapid in decedents. At ages 80-89 years, mean BMI in decedents was 26.1 (4.7) compared with 27.1 (4.4) Kg/m2 in survivors. After adjusting for age and covariates, mean BMI declined in the five years before death. From 9 to 5 years before death or end of study, adjusted mean BMI was 0.51 (95% confidence interval 0.24 to 0.78) Kg/m2 lower for decedents than survivors; and from four to zero years before death, 1.55 (1.26 to 1.84) Kg/m2 lower in decedents. Conclusions: In community-dwelling older adults, mean body mass index enters an accelerating decline during five years before death. Reverse causation may account for the association of lower BMI with mortality.

Abstract Inspiring by Martinson and Berridge’s (2015) systematic review, the current definition of successful aging (SA) fails to acknowledge the laypeople’s conceptualization of SA. Adopting a mixed-method approach, two studies were conducted with the aim of soliciting older adults’ perceptions of SA and to develop a multidimensional instrument for assessing SA. Study 1 was a qualitative study and 27 community-dwelling older adults (Mage=68.07 years, SD=7.10, range=60–83; 56.3% females) were interviewed. Interview transcripts were analyzed, and seven themes were emerged. An initial item pool for the Successful Aging Scale (SAS) was then established based on these themes as well as those in the SA literature, such as acceptance and independence. Study 2 was a survey study which was conducted among 414 community-dwelling older adults (Mage=64.50 years, SD=4.01, range=60–82; 55.3% females) to identify optimal items for constitution of the SAS. Exploratory factor analysis revealed a 12-factor solution, accounting for 62% of the variance. The 12 factors are adequate health, perceived constraints, flexible attitudes toward life, acceptance of age-related change, life embracement, active engagement, harmonious family, supportive friendship, civic awareness, social contribution, living independently, and adaptive coping strategies. The 12 factors exhibit similar strength of associations with most of the well-being measures, but certain factors show stronger correlation with depressive symptoms and social relationship, suggesting the uniqueness of each factor. Overall, the SAS demonstrates promising psychometric properties. These findings disclose that the older adults’ perceptions of SA could cover broader dimensions than those in Rowe and Kahn’s model (1997).

Context: Falls and loss of autonomy are often attributed in large part to musculoskeletal impairments in later adulthood. Age-related declines in flexibility contribute to late adulthood musculoskeletal impairment. The novel sitting-rising test has been proposed to be a quick, effective screening of musculoskeletal fitness, fall risk, and all-cause mortality in older adults. The timed up and go and 5 times sit-to-stand tests are two of the 3 most evidence-supported performance measures to assess fall risk. Objective: This study aimed to determine if 5 weeks of flexibility training could increase sitting-rising test, timed up and go, and 5 times sit-to-stand scores in community-dwelling older adults. Participants: Forty-seven adults aged 60 years and older (mean age = 66.7 y, SD = 4.1) participated in this study. Participants completed a static stretching protocol consisting of 3 weekly 1-hour stretching sessions. Results: The protocol improved flexibility as seen in sit-and-reach scores and improved scores on all outcome variables. Specifically, there was a significant increase in sitting-rising test scores from preintervention (M = 7.45, SD = 1.45) to postintervention (M = 8.04, SD = 1.36), t(42) = −5.21, P < .001. Timed up and go scores demonstrated a significant decrease from preintervention (M = 8.85, SD = 1.32) to postintervention (M = 8.20, SD = 1.35), t(46) = 5.10, P < .001. Five times sit-to-stand scores demonstrated a significant decrease from preintervention (M = 12.57, SD = 2.68) to postintervention (M = 10.46, SD = 2.06), t(46) = 6.62, P < .001. Finally, significant increases in sit-and-reach scores were associated with improved functional performance (r = −.308, P = .03). Conclusion: Findings suggest that flexibility training can be an effective mode of low-level exercise to improve functional outcomes. Static stretching may help to improve musculoskeletal health, promote autonomy, and decrease mortality in community-dwelling older adults.

Abstract The beneficial effects of brain-derived neurotrophic factor (BDNF)—a member of the neurotrophin family—on cognitive function or dementia are well established in both rodents and human beings. In contrast, little is known about the association of proBDNF—a precursor protein with opposing neuronal effects of BDNF—with cognitive function in non-demented older adults. We analyzed brain magnetic resonance imaging findings of 256 community-dwelling older adults (mean age of 68.4 years). Serum BDNF and proBDNF levels were measured by quantitative enzyme-linked immunosorbent assay. Logistic regression analysis revealed that older age, less physical activity, hippocampal atrophy, and lower BDNF levels were independently associated with memory impairment determined by the Rivermead Behavioral Memory Test. Path analysis based on structural equation modeling indicated that age, sport activity, hippocampal atrophy and BDNF but not proBDNF were individually associated with Rivermead Behavioral Memory Test scores. These findings suggest that impaired BDNF function, in addition to physical inactivity and hippocampal atrophy, is associated with age-related memory impairment. Therefore, BDNF may be a potential target for dementia prevention.
