Do Personality Traits Influence the Association Between Depression and Dementia in Old Age?

Depression and personality traits are independent predictors of dementia or cognitive impairment. Despite the well-established relationship between these two psychosocial factors and dementia, no research has been documented on how personality traits can influence dementia in older adults exhibiting depressive symptoms. This study explores the influence of personality traits on the association between change in depression and dementia in old age. A population-based longitudinal cohort study involving two waves of data collected 5 years apart, containing 2210 American older adults, from the National Social Life, Health, and Aging Project to explore if personality traits influence how change in depression predicts the development of dementia. We assessed these relationships while adjusting for sociodemographic characteristics. Change in depression increased the likelihood of dementia at T2 by 4.2% (AOR = 1.04, p = 0.019) in the co-variate adjusted model. Personality traits, overall, did not influence how depression predicts the development of dementia. However, agreeableness individually nullified the effect of depression on the development of dementia, whereas extraversion was the only personality trait that significantly predicted dementia. Prosocial behaviors should be promoted in old age as these appear to be protective. In addition, early life education and a strong social support can keep the depression–dementia spectrum at bay in old age.

COVID-19 Across the Landscape of Long-Term Care in Alameda County: Heterogeneity and Disparities

Throughout the pandemic, public health and long-term care professionals in our urban California county have linked local and state COVID-19 data and performed observational exploratory analyses of the impacts among our diverse long-term care facilities (LTCFs). Case counts from LTCFs through March 2021 included 4309 (65%) in skilled nursing facilities (SNFs), 1667 (25%) in residential care facilities for the elderly (RCFEs), and 273 (4%) in continuing care retirement communities (CCRCs). These cases led to 582 COVID-19 resident deaths and 12 staff deaths based on death certificates. Data on decedents’ age, race, education, and country of birth reflected a hierarchy of wealth and socioeconomic status from CCRCs to RCFEs to SNFs. Mortality rates within SNFs were higher for non-Whites than Whites. Staff accounted for 42% of LTCF-associated COVID-19 cases, and over 75% of these staff were unlicensed. For all COVID-19 deaths in our jurisdiction, both LTCF and community, 82% of decedents were age 65 or over. Taking a comprehensive, population-based approach across our heterogenous LTCF landscape, we found socioeconomic disparities within COVID-19 cases and deaths of residents and staff. An improved data infrastructure linking public health and delivery systems would advance our understanding and potentiate life-saving interventions within this vulnerable ecosystem.

Physical and Mental Health Differences Reported by Three Age Groups of Older Adults With Diabetes

Most studies have classified older adults with diabetes into one group despite substantial variation in health status across different stages of late adulthood. In this study, we examined difference in self-reported physical and mental health among three age groups of older adults with diabetes. Using data from the 2016 National Social Life, Health and Aging Project, Wave 3, we classified 424 individuals diagnosed with diabetes into three age groups, young-old (YO): 50–64 years; middle-old (MO): 65–74; and oldest old (OO): 75+ years. A one-way multivariate analysis of covariance was used to assess group differences, followed by univariate analyses. The results indicate that the YO group reported significantly lower physical health and higher depression than the MO group and higher levels of loneliness than the MO and OO groups. These findings indicate that physical and mental health may differ among different age groups of older adults with diabetes and suggest that the YO might be more vulnerable to diminished physical and mental health than the other age groups.

Sleep Quality Among Informal Caregivers During the COVID-19 Pandemic: A Cross-Sectional Study

Sleep is an integral component of health. The impact of the COVID-19 pandemic on sleep quality among informal caregivers, individuals who provide unpaid care or assistance to family members or friends, assisting older adults is not well understood. Therefore, informal caregivers in the United States providing care for individuals aged 50+ were recruited via Amazon’s Mechanical Turk, an online platform for enrolling study participants into social and behavioral science research, to complete an online survey. The sample of informal caregivers ( n = 835) was 69% male and 55% non-Hispanic. Multivariable linear regression models were constructed to assess the associations between sleep disturbance scores (SDS) and sleep-related impairment scores (SIS) and caregiving-related measures (hours caregiving/week, length of time spent caregiving, and caregiver burden), demographics, and region of the United States. The analysis determined that Black (β = 2.6, 95% CI [−4.3, −0.9]) and Asian informal caregivers (β = −1.8, 95% CI [−3.4, −0.3]) had lower mean SIS than White caregivers, the referent group. In addition, increasing caregiver burden was associated with increased SDS (β = 0.8, 95% CI [0.6, 1.0]) and SIS (β = 1.3, 95% CI [0.7, 1.6]). In conclusion, higher caregiver burden was associated with higher SIS and SDS, suggesting that informal caregivers' sleep should be assessed, and when needed interventions should be offered.

Sensory Processing Abnormalities in Community-Dwelling Older Adults with Cognitive Impairment: A Mixed Methods Study

Mild cognitive impairment (MCI) or dementia often leads to behavioral and psychiatric symptoms of dementia (BPSD). Sensory processing abnormalities may be associated with BPSD. The purpose of this study was to explore relationships among sensory processing, behavior, and environmental features within the homes of people with MCI or dementia. This project used mixed methods to assess participants’ sensory processing, care partner perspectives on behaviors, and in situ observations of the home environment. Nine participants with cognitive impairment (MCI n = 8, early dementia = 1) and their care partners were included. Seven participants with cognitive impairment were reported to have abnormal sensory processing. Findings suggest that unique environmental adaptations, tailored to personal and sensory preferences for each participant, were associated with a decreased level of behavioral disruption during the observation periods. Implementing sensory-based approaches to maximize environment adaptation may be beneficial in reducing disruptive behaviors for adults with cognitive impairment.

Physical Activity and Aging: Exploring Motivations of Masters Swimmers

Physical activity benefits the health of older adults (e.g., lowering risk of cardiovascular disease, depression, dementia, and falls). However, less than one in four Americans meets guidelines for physical activity and inactivity increases with age. Masters athletes are exemplary because of their remarkable physical functioning. Swimming is a global, fast-growing sport in Masters athletics. This qualitative study explored motivations and barriers of 18 older adult members of a Masters swim club in Southern California. Guided by a primary research question: Why do Masters swimmers choose swim late in life, when most of their age cohort are becoming less physically active, semi-structured interviews delved into the lived experiences of the participants, and solicited peer feedback. Four main themes emerged: (1) I Just Love the Sensation of Being in the Water, (2) Tell Your Body What to Do Instead of the Other Way Around, (3) Make a Commitment to Your Friends That You’re Going to be There, and (4) I’ve Never Gone This Long in My Life Without Swimming. Participants expressed longing and regret that they could not swim due to COVID risk and safety guidelines. These findings can be used to design community programs to promote lifelong physical activity participation.

The Biopsychosocial Impact of COVID-19 on Older Adults

COVID-19 has spread rapidly around the world and taken over 2.6 million lives. Older adults experience disproportionate morbidity and mortality from the disease because increasing age and the presence of comorbidities are important predictors of negative outcomes. Lasting effects of COVID-19 have been described after recovery from the acute illness despite eradication of the virus from the body. The impact of COVID-19 on a person’s biological health post-infection is observed in multiple systems including respiratory, cardiac, renal, haematological, and neurological. Psychological dysfunction following recovery is also prevalent. Social factors such as distancing and stay at home measures leave older adults isolated and food insecure; they also face intertwined financial and health risks due to the resulting economic shutdown. This study examines the effects of COVID-19 on older adults using the biopsychosocial model framework.

Association Between Tobacco Consumption and Self-Reported Visual Impairment in Adults of High-Altitude Andean Communities of Peru

To determine the association between tobacco consumption and self-reported visual impairment. We performed a cross-sectional study based on an original cohort study. A non-probabilistic sampling was performed to invite 413 patients of 60 years or more from 11 high-altitude Andean communities (altitude higher than 1500 m above sea level) of Peru between 2013 and 2017. Demographic data and information on tobacco consumption were collected. Associations were determined using a Poisson regression model with 95% confidence intervals (CI). Of the 413 participants, 141 (34.14%) were men and 49 (11.86%) were tobacco users. In the adjusted model, tobacco users presented a high probability of visual impairment with a prevalence ratio of 1.32 (95% CI: 1.18–1.97). We also found that having two or more comorbidities 2.19 (95% CI: 1.53–3.15), receiving health assistance in a pharmacy 3.75 (95% CI: 1.97–7.16), and coffee consumption 1.67 (95% CI: 1.26–2.21) were factors significantly associated with self-reported visual impairment. We determined that in Peruvian high-altitude Andean communities, visual impairment was more frequent in individuals reporting tobacco consumption, taking alternative medicine, going directly to a drug store without primary care physician consultation, having more than one comorbidity, and coffee consumption.

Predictors of Biological Age: The Implications for Wellness and Aging Research

As healthspan and lifespan research breakthroughs have become more commonplace, the need for valid, practical markers of biological age is becoming increasingly paramount. The accessibility and affordability of biological age predictors that can reveal information about mortality and morbidity risk, as well as remaining years of life, has profound clinical and research implications. In this review, we examine 5 groups of aging biomarkers capable of providing accurate biological age estimations. The unique capabilities of these biomarkers have far reaching implications for the testing of both pharmaceutical and non-pharmaceutical interventions designed to slow or reverse biological aging. Additionally, the enhanced validity and availability of these tools may have increasingly relevant clinical value. The authors of this review explore those implications, with an emphasis on lifestyle modification research, and provide an overview of the current evidence regarding 5 biological age predictor categories: Telomere length, composite biomarkers, DNA methylation “epigenetic clocks,” transcriptional predictors of biological age, and functional age predictors.

The COVID-19 Pandemic Reignites the Need for Person-Centered Gerontological Approach

The national response to the COVID-19 pandemic pressed gerontologists to reflect, redesign, and reform services supporting older adults. Efforts to isolate a peer cohort to stabilize and maintain a standard of health had adverse outcomes and added pressure conflicting with autonomy and individual desires. In this, person-centered care emerges as a meaningful archetype to address dignity and independence. This article presents views from academics and practitioners across an interdisciplinary spectrum, arising from a webinar hosted by Georgetown University Program in Aging & Health. A description of personhood as an extension of the humanities is followed by a robust discussion of safety and autonomy for older adults during the COVID-19 pandemic. We examine the necessary commute between critical gerontological theory and the practice of humanistic gerontology. Further, this article disentangles humanism and person-centered care to balance autonomy and safety for older adults in congregate living situations and focuses on specific populations: people with dementia and their care partners. Discussion on the importance of person-centered policy development in a public health pandemic is also explored. The article concludes with a call to action for the adoption of a comprehensive person-centered care model across the fields of gerontology and geriatric medicine.
