Physical and recreational activities are behaviors that may modify risk of late-life cognitive decline. We sought to examine the role of retrospectively self-reported midlife (age 40) physical and recreational activity engagement – and self-reported change in these activities from age 40 to initial study visit – in predicting late-life cognition.

Data were obtained from 898 participants in a longitudinal study of cognitive aging in demographically and cognitively diverse older adults (Age: range = 49–93 years, M = 75, SD = 7.19). Self-reported physical and recreational activity participation at age 40 and at the initial study visit were quantified using the Life Experiences Assessment Form. Change in activities was modeled using latent change scores. Cognitive outcomes were obtained annually (range = 2–17 years) using the Spanish and English Neuropsychological Assessment Scales, which measure verbal episodic memory, semantic memory, visuospatial processing, and executive functioning.

Physical activity engagement at age 40 was strongly associated with cognitive performance in all four domains at the initial visit and with global cognitive slope. However, change in physical activities after age 40 was not associated with cognitive outcomes. In contrast, recreational activity engagement – both at age 40 and change after 40 – was predictive of cognitive intercepts and slope.

Retrospectively self-reported midlife physical and recreational activity engagement were strongly associated with late-life cognition – both level of performance and rate of future decline. However, the data suggest that maintenance of recreational activity engagement (e.g., writing, taking classes, reading) after age 40 is more strongly associated with late-life cognition than continued maintenance of physical activity levels.

We first tested a successful aging model, which included biomedical and psychosocial indicators. Next, we tested the assumptions on the social network characteristics of the socioemotional selectivity theory in a model where the outcome variable is successful aging.

Cross-sectional study.

The study was carried out in municipal centers and nursing homes.

A total of 478 adults (Mean age = 72.11, SD = 10.43) were enrolled.

Psychological Well-being Scale, Life Satisfaction Scale, Future Time Perspective, Katz Index of Independence in Activities of Daily Living Scale, Lawton Instrumental Activities of Daily Living Scale, and Mini-Mental State Examination Test were completed.

The structural equation modeling analyses indicated that higher social satisfaction mediated the association of the future time perspective with successful aging. Furthermore, there was another significant indirect sequential path from the future time perspective to successful aging. The path was first via the number of close social partners and second, social satisfaction.

The findings highlight the importance of social satisfaction in the process of successful aging and provide novel evidence that the socioemotional selectivity theory can be considered as a biopsychosocial model of successful aging in future studies.

We explored the ‘coping reflections’ of elderly couples living alone (without any other family members) during the COVID-19 pandemic in urban Odisha, India.

Evidence worldwide suggests that older people are at increased risk from COVID-19 adverse outcomes and experience greater stress. In our previous community-based study urban dwelling, particularly elderly participants, and living alone reported higher pandemic-associated health care challenges than their rural and residing-with-family counterparts. We intended to explore how the elderly couples living alone coped through this challenging yet stressful situation during the COVID-19 pandemic and what were their key strategies adopted toward this.

We conducted telephonic in-depth interviews (IDIs) with 11 urban elderly couples living alone in Bhubaneswar city of Odisha, India using a semi-structured interview guide. All IDIs were digitally recorded, transcribed into the original language, and translated to English. We used a thematic approach for analysis.

Four themes emerged: (1) Risk appraisal and feeling vulnerable; (2) Safeguarding against COVID-19; (3) Managing routine health care and emergency; and (4) Pursuing mental and psychological well-being. Although fear, anxiety, and loneliness were continuing stressors, many of them learnt to adapt and emerge resilient with the evolving situation. Various elements at the individual, family, community, and organizational levels were conducive to better coping. The companionship and complementary support of spouse, self-health literacy, and digital efficacy, virtual connectedness with family and friends, availability of community pharmacy and diagnostic services in the vicinity, support of neighbors, reengaging with creative leisure time activity, and assurance of a responsive administration at the time of emergency helped them to cruise through the pandemic. Furthermore, watching the re-telecast of prime time serials made these elderly fondly remember their own youth time memories. Self-health monitoring, indoor physical exercise, spiritual practices, continuation of previous prescription, telephonic advice of physicians were add-on strategies that facilitated their physical and psychological well-being during the pandemic.

To identify novel associations between modifiable physical and health variables, Alzheimer’s disease (AD) biomarkers, and cognitive function in a cohort of older adults with Mild Cognitive Impairment (MCI).

Metrics of cardiometabolic risk, stress, inflammation, neurotrophic/growth factors, AD, and cognition were assessed in 154 MCI participants (Mean age = 74.1 years) from the Alzheimer’s Disease Neuroimaging Initiative. Partial Least Squares analysis was employed to examine associations among these physiological variables and cognition.

Latent variable 1 revealed a unique combination of AD biomarkers, neurotrophic/growth factors, education, and stress that were significantly associated with specific domains of cognitive function, including episodic memory, executive function, processing speed, and language, representing 45.2% of the cross-block covariance in the data. Age, body mass index, and metrics tapping basic attention or premorbid IQ were not significant.

Our data-driven analysis highlights the significant relationships between metrics associated with AD pathology, neuroprotection, and neuroplasticity, primarily with tasks tapping episodic memory, executive function, processing speed, and verbal fluency rather than more basic tasks that do not require mental manipulation (basic attention and vocabulary). These data also indicate that biological metrics are more strongly associated with episodic memory, executive function, and processing speed than chronological age in older adults with MCI.

SuperAgers are adults over the age of 80 with superior episodic memory performance and at least average-for-age performance in non-episodic memory domains. This study further characterized the neuropsychological profile of SuperAgers compared to average-for-age episodic memory peers to determine potential cognitive mechanisms contributing to their superior episodic memory performance.

Retrospective analysis of neuropsychological test data from 56 SuperAgers and 23 similar-age peers with average episodic memory was conducted. Independent sample t-tests evaluated between-group differences in neuropsychological scores. Multiple linear regression determined the influence of non-episodic memory function on episodic memory scores across participants.

As a group, SuperAgers had better scores than their average memory peers on measures of attention, working memory, naming, and speeded set shifting. Scores on tests of processing speed, visuospatial function, verbal fluency, response inhibition, and abstract reasoning did not differ. On an individual level, there was variability among SuperAgers with regard to non-episodic memory performance, with some performing above average-for-age across cognitive domains while others performed in the average-for-age range on non-memory tests. Across all participants, attention and executive function scores explained 20.4% of the variance in episodic memory scores.

As a group, SuperAgers outperformed their average memory peers in multiple cognitive domains, however, there was considerable intragroup variability suggesting that SuperAgers’ episodic memory strength is not simply related to globally superior cognitive functioning. Attention and executive function performance explained approximately one-fifth of the variance in episodic memory and maybe areas to target with cognitive interventions.

This study examined Na intake and identified the major food sources of Na in healthy Chinese adults aged ≥50 years in Hong Kong.

Participants who completed a baseline assessment of a randomised controlled trial assessing the effectiveness of exercise and nutrition supplementation on improving physical and cognitive functions were included. A single 24-h urine sample and a 3-d diet record were used to measure urinary Na excretion and dietary intake, respectively. The compliances to the WHO (<5 g/d) and China Nutrition Society (<6 g/d) recommendations for salt intake were assessed based on the urinary Na excretion. The relative contribution of sixteen food groups to the dietary Na intake was expressed as percentages. Associations between food groups and urinary Na excretion were analysed using multiple linear regression.

Community facilities.

Totally, 114 healthy Chinese adults (mean age 60·6 years, 55 % women).

The mean urinary Na excretion over 24-h was 2876·6 ± 1249·4 mg/d (7·3 ± 3·2 g salt/d). Overall, 22·8 % of participants met the WHO recommendation and 34·2 % met the Chinese Nutrition Society recommendation for salt intake. The major food sources of dietary Na intake were condiments (42·4 %), cereals and their products (16·8 %) and soups (13·5 %). Higher intakes of seafood and nuts were associated with lower urinary Na excretion.

Public health strategies should target healthy Chinese adults in Hong Kong to modify the current patterns of Na intake. Targeting condiments, cereals and their products and soups will be an important strategy to reduce their Na intake.

Positive psychiatry offers an unique approach to promote brain health and well-being in aging populations. Minimal interventions through behavioral activation to promote wellness are increasingly available using self-guided apps, yet little is known about the effectiveness of app technology or the difference between clinician-supported behavioral activation versus self-guided app methodologies.

Investigate the difference in users and outcomes between two methods of the Fountain of Health (FoH) positive psychiatry intervention for behavioral activation to promote brain health and well-being: (1) clinician-assisted and (2) independent app use for behavioral self-management.

As part of a larger knowledge translation intervention in positive psychiatry, two specific methods of a behavioral activation intervention were retrospectively compared.

Two subsets of patients were compared; 254 clinician-assisted patients; 333 independent app users.

A minimal positive psychiatry intervention in frontline care using the FoH health and behavior change clinical tools

Main outcomes were changes in psychological (health and resilience, well-being scores) and behavioral indices (goal attainment, items of goal SMART-ness). User profiles (age, sex and completion rates) were also compared.

Clinician-assisted patients were more likely to be male, older, and have lower health and resilience scores at baseline. Clinician-assisted patients had notably higher completion rates (99.2% vs. 10.8%). Psychological outcomes (improved health and resilience, and well-being) were similar regardless of intervention method for those who completed the intervention. Behavioral outcomes revealed clinician-assisted patients set goals that better adhered to key goal-setting items.

Clinician–patient relationships appear to be an important factor for intervention completion and behavioral outcomes, while further exploration of best practices for intervention completion using health apps in clinical practice is needed. A preliminary goal-setting methodology for effective behavioral activation, to promote brain health and wellness, is given.

Recently, there has been a growing interest in examining forms of illness-related resilience. This study examines associations between lifestyle behavioral factors and multimorbidity resilience (MR) among older adults.

Using baseline data from the Comprehensive Cohort of the Canadian Longitudinal Study on Aging, we studied 6,771 Canadian adults aged 65 or older who reported two or more of 27 chronic conditions, and three multimorbidity clusters: cardiovascular/metabolic, osteo-related, and mental health. Associations were explored using hierarchical linear regression modeling, controlling for sociodemographic, social/environmental, and illness context covariates.

Among older adults with two or more illnesses, as well as the cardiovascular/metabolic and osteo-related illness clusters, having a non-obese body mass, being a non-smoker, satisfaction with quality of sleep, having a good appetite, and not skipping meals are associated with MR. However, the mental-health cluster resulted in different behavioral lifestyle associations, where MR was not associated with obesity, smoking, or appetite, but inactivity demonstrated moderate positive associations with MR.

While there are similar patterns of lifestyle behaviors across multimorbidity and multimorbidity clusters involving physiological chronic illnesses, those associated with mental health are distinct. The results have implications for healthy aging among persons coping with multimorbidity.
