Understanding periods of the year associated with higher risk for falling and less physical activity may guide fall prevention and activity promotion for older adults. We examined the relationship between weather and seasons on falls and physical activity in a three-year cohort of older adults with glaucoma. Participants recorded falls information via monthly calendars and participated in four one-week accelerometer trials (baseline and per study year). Across 240 participants, there were 406 falls recorded over 7569 person-months, of which 163 were injurious (40%). In separate multivariable regression models incorporating generalized estimating equations, temperature, precipitation, and seasons were not significantly associated with the odds of falling, average daily steps, or average daily active minutes. However, every 10 °C increase in average daily temperature was associated with 24% higher odds of a fall being injurious, as opposed to non-injurious (p = 0.04). The odds of an injurious fall occurring outdoors, as opposed to indoors, were greater with higher average temperatures (OR per 10 °C = 1.46, p = 0.03) and with the summer season (OR = 2.69 vs. winter, p = 0.03). Falls and physical activity should be understood as year-round issues for older adults, although the likelihood of injury and the location of fall-related injuries may change with warmer season and temperatures.

The Relationship

The aim of this study was to longitudinally investigate the association between resilience and mental health in older adults and to determine the influence of physical activity on this relationship. A total of 291 older adults were included in a 2-year follow-up study. Adjusted linear regression models evaluated the association between resilience at baseline and mental health after 2 years in sufficiently and insufficiently physically active older adults. A negative correlation was found between resilience at baseline and depression, anxiety, and stress after 2 years for the overall sample. This association changed after stratifying the group. Sufficiently physically active individuals made greater use of the resilience components “Self-Sufficiency” and “Perseverance,” whereas insufficiently physically active individuals made greater use of “Meaning of Life” and “Existential Singularity.” Physical activity can influence the relationship between resilience and mental health. These results can help guide the devising of more effective interventions for this age group.

Community Dwelling Older Adults

Background: Information on the body composition of inhabitants of remote communities during the SARS-CoV-2 pandemic is limited. Using a longitudinal population-based study design, we assessed the association between SARS-CoV-2 infection and changes in body composition. Methods: Community-dwelling older adults living in a rural Ecuadorian village received body composition determinations before and 1 year after the pandemic as well as serological tests for detection of SARS-CoV-2 antibodies. The independent association between SARS-CoV-2 infection and abnormalities in body composition at follow-up was assessed by fitting linear mixed models for longitudinal data. Results: Of 327 enrolled individuals, 277 (85%) received baseline and follow-up body composition determinations, and 175 (63%) of them became SARS-CoV-2 seropositive. Overall, diet and physical activity deteriorated during the follow-up. Multivariate random-effects generalized least squares regression models that included the impact of time and seropositivity on follow-up body composition, showed that neither variable contributed to a worsening in body composition. Multivariate logistic regression models disclosed that the serological status at follow-up cannot be predicted by differences in body composition and other baseline covariates. Conclusions: Study results suggest no increased susceptibility to SARS-CoV-2 infection among older adults with abnormal body composition and no significant changes as a result of worse physical activity and dietary habits or seropositivity during the length of the study. Together with a previous study in the same population that showed decrease in hand-grip strength after SARS-CoV-2, results confirm that dynapenia (and not sarcopenia) is associated with SARS-CoV-2 infection in older adults.

The Relationship

Individuals’ lifestyles play an important role in healthcare costs. A large part of these costs is derived from hospitalizations. With the aim of determine the relationship between lifestyle and the likelihood of hospitalization and associate costs in older adults, this study used the Survey of Health, Aging, and Retirement in Europe. Generalized regression models for panel data were developed and adjusted hospitalization costs derived from the length of hospital stay were also estimated. The average adjusted cost of hospitalization was I$ 9901.50 and the analyses showed that performing weekly physical activity significantly reduces the probability of hospitalization (OR: 0.624) and its costs (I$ 2594.5 less per person per year than subjects who never performed physical activity). Muscle strength plays an important role in this relationship and eating habits are not of great significance. Furthermore, we found interesting differences in the frequency and costs of hospitalization between subjects by country.

Abstract Objective This study was aimed to examine the relationship between duration of infant exposure to a moderate-to-large patent ductus arteriosus (PDA) shunt and the risk of developing bronchopulmonary dysplasia (BPD) or death before 36 weeks (BPD/death). Study Design Infants <28 weeks' gestation who survived ≥7 days (n = 423) had echocardiograms performed on day 7 and at planned intervals. Results In multivariable regression models, BPD/death did not appear to be increased until infants had been exposed to a moderate-to-large PDA for at least 7–13 days: OR (95%CI) (referent = closed or small PDA): moderate-to-large PDA exposure for <7 days: 0.38 (range, 0.10–1.46); for 7 to 13 days = 2.12 (range, 1.04–4.32); for ≥14 days = 3.86 (range, 2.15–6.96). Once the threshold of 7 to 13 days had been reached, additional exposure (≥14 days) did not significantly add to the increased incidence of BPD/death: (referent exposure = 7–13 days) exposure for 14 to 27 days = 1.34 (range, 0.52–3.45); for 28 to 48 days = 2.34 (range, 0.88–6.19); for ≥49 days = 1.80 (range. 0.59–5.47). A similar relationship was found for the outcome of BPD-alone. Conclusion Infants < 28 weeks' gestation required at least 7 to 13 days of exposure to a moderate-to-large PDA before a significant increase in the incidence of BPD/death was apparent. Once this threshold was reached additional exposure to a moderate-to-large PDA did not significantly add to the increased incidence of BPD/death.

Abstract COVID-19 public health recommendations have prohibited many older adults from attending in-person physical activity (PA) programs that improve physical function and promote functional independence. Most PA programs have shifted towards a video conference (VC) format, but this modality has been noted to “flatten” the social experience which is fundamental for lasting behavior change. Virtual reality (VR) is now designed for immersion and place-presence and may be better suited for instilling a feeling of social connection, which will likely improve physical function. The purpose of this study was to evaluate differences in physical function after a 4-week in-home VR or VC based PA intervention. Low-active adults (66.8±4.8 years) were randomized to VR (n=5) or VC (n=4) based PA counselling and instructed to find activities that were intrinsically motivating. VR participants were asked to select pre-approved available active games in addition to enjoyable real-world activities. ANCOVA models were used to explore group differences in six-minute walk distances across time. Results are reported using η^2 effect sizes based on the small sample size. After controlling for baseline values, the ANCOVA models revealed a moderate-to-large magnitude effect for distance traveled during the six-minute walk test (η^2=.10). Additionally, the VR group participants walked 42.63 meters further, which approaches a clinically meaningful difference. These promising early findings suggest there is value to exploring the impact of VR-delivered, group-mediated activity promotion on physical functioning in older adults. Future research should investigate aspects of VR that promote increased social connection and physical function in the older adult population.

Abstract Older adults in residential care settings are four times more likely than those not living in care facilities to experience falls. Yet, fall prevention efforts at long-term care settings are under-resourced, under-regulated, and under-studied. To address this gap, we developed and studied the impact of a specialty clinical, Fall Prevention Care Management (FPCM), for nursing students to decrease older adults’ fall risks. We enrolled assisted living residents that facility liaison identified as being high fall risk (fall rates or fall risk were not tracked at the study sites) and MOCA ≥15, in 2 assisted living facilities in Northwest USA. Participants received weekly, 1-hour, individual, semi-structured, Motivational Interviewing-based care management visits by same students over 6 visits. Changes in fall risks were measured by the CDC STEADI assessment (unsteadiness & worry), Falls Self-Efficacy Scale International-Short (FESI-S), and Falls Behavioral Scale (FAB). Twenty-five residents completed the study. Students addressed the following (multiple responses possible): emotional needs (n=23), improved motivation to prevent falls (n=21), and individualized education/coaching (i.e., exercise, mobility aids) (n=10-17). FESI-S score improved from 16.0 to 14.4 (p=.001; decreased fear. FAB score improved from 2.94 to 3.10 (p=.05; more frequent fall prevention behaviors). Frequency of those who felt steady while standing or walking increased (24% to 40%, p=.07) and those who did not worry about falling increased (20% to 36%, p=.08). FPCM clinical offered valuable opportunity to address unmet care needs of older adults to reduce fall risks.

The Relationship

Abstract Previous cross-sectional research suggests that age-related decreases in Rapid-Eye Movement (REM) sleep may contribute to poorer cognitive functioning (CF); however, few studies have examined the relationship at the intraindividual level by measuring habitual sleep over multiple days. Applying a 14-day daily diary design, the current study examines the dynamic relationship between REM sleep and CF in 69 healthy older adults (M age=70.8 years, SD=3.37; 73.9% female; 66.6% completed at least an undergraduate degree). A Fitbit device provided actigraphy indices of REM sleep (minutes and percentage of total sleep time), while CF was measured four times daily on a smartphone via ambulatory cognitive tests that captured processing speed and working memory. This research addressed the following questions: At the within-person level, are fluctuations in quantity of REM sleep associated with fluctuations in next day cognitive measures across days? Do individuals who spend more time in REM sleep on average, perform better on cognitive tests than adults who spend less time in REM sleep? A series of multilevel models were fit to examine the extent to which each index of sleep accounted for daily fluctuations in performance on next day cognitive tests. Results indicated that during nights when individuals had more REM sleep minutes than was typical, they performed better on the working memory task the next morning (estimate = -.003, SE = .002, p = .02). These results highlight the impact of REM sleep on CF, and further research may allow for targeted interventions for earlier treatment of sleep-related cognitive impairment.

The Impact

Despite growing health disparities in Latino populations related to lack of physical activity (PA), little is known regarding the impact of social networks on PA and sedentary behavior among a sample of Latino fathers residing in functionally rural colonias. Fathers wore accelerometers and responded to questions regarding their self-efficacy and characteristics of who they were active with most often. Fathers (n = 47) attained a mean of 73.3 min of moderate-to-vigorous PA (SD = 23.8) per day and were sedentary for a mean of 364.0 min (SD = 74.4) per day. In total, fathers reported 205 alters and significantly more family members (M = 3.60, SD = 1.64) than friends (M = 0.77, SD = 1.37). Sedentary time was positively associated with number of peers and inversely related to the number of children reported. Minutes of moderate-to-vigorous PA was significantly associated with greater self-efficacy and number of family members reported. This study contributes to the evidence by further examining PA correlates of Latino fathers from functionally rural colonia communities. Additionally, this study supported both family systems theory and the socio–ecological model as it details the interpersonal and familial influences of PA behavior. Thus, supports for family activity promotion and programs which impact familial norms and activity at the family level may be particularly useful.

The Impact

<b><i>Background:</i></b> Age-related changes in biological processes such as physiological dysregulation (the progressive loss of homeostatic capacity) vary considerably among older adults and may influence health profiles in late life. These differences could be related, at least in part, to the impact of intrinsic and extrinsic factors such as sex and physical activity level (PAL). <b><i>Objectives:</i></b> The objectives of this study were (1) to assess the magnitude and rate of changes in physiologi­cal dysregulation in men and women according to PAL and (2) to determine whether/how sex and PAL mediate the apparent influence of physiological dysregulation on health outcomes (frailty and mortality). <b><i>Methods:</i></b> We used data on 1,754 community-dwelling older adults (age = 74.4 ± 4.2 years; women = 52.4%) of the Quebec NuAge cohort study. Physiological dysregulation was calculated based on Mahalanobis distance of 31 biomarkers regrouped into 5 systems: oxygen transport, liver/kidney function, leukopoiesis, micronutrients, and lipids. <b><i>Results:</i></b> As expected, mean physiological dysregulation significantly increased with age while PAL decreased. For the same age and PAL, men showed higher levels of physiological dysregulation globally in 3 systems: oxygen transport, liver/kidney function, and leukopoiesis. Men also showed faster global physiological dysregulation in the liver/kidney and leukopoiesis systems. Overall, high PAL was associated with lower level and slower rate of change of physiological dysregulation. Finally, while mortality and frailty risk significantly increased with physiological dysregulation, there was no evidence for differences in these effects between sexes and PAL. <b><i>Conclusion:</i></b> Our results showed that both sex and PAL have a significant effect on physiological dysregulation levels and rates of change. Also, although a higher PAL was associated with lower level and slower rate of change of physiological dysregulation, there was no evidence that PAL attenuates the effect of physiological dysregulation on subsequent declines in health at the end of life. Substantial work remains to understand how modifiable behaviors impact the relationship between physiological dysregulation, frailty, and mortality in men and women.
