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.

Abstract Background Previous studies reported that physical activity (PA) could prevent frailty, but the longitudinal evidence between PA volume and frailty is scarce. Additionally, the impact of daily walking time on the risk of frailty is unclear. This study aimed to examination the association of incident frailty with PA volume and daily walking time among Japanese community-dwelling older adults. Methods About 485 participants aged 70–74 years from the Japan Gerontological Evaluation Study were included in this study. Frailty was assessed at baseline and 3 years later by using the Kaigo-Yobo Checklist. PA was assessed using the short-term International Physical Activity Questionnaire. Logistic regression was performed to calculate relative risk (RR) with 95% confidence intervals (CIs) after adjusting for potential confounders. Results After 3 years of follow-up, 46 new frailty cases were recorded. The association of frailty incidence with both PA volume and daily walking time presented a U-shaped curve, albeit not statistically significant. After adjusting for potential confounding factors, walking for 0.5–1 h per day displayed a greater association with decreased frailty risk (RR, 0.35; 95% CI, 0.12–0.98) than higher levels of daily walking time. We did not observe an association between PA volume and subsequent frailty. Conclusions Walking for 0.5–1 hour/day significantly decreases frailty risk. Incorporating a moderate level of regular walking into the daily lives of older adults may postpone the onset of frailty and improve the ageing process. Further studies are needed to investigate the impact of higher PA levels on frailty risk.

Community Dwelling Older Adults

This study aimed to assess the impact of malnutrition on the 5-year evolution of physical performance, muscle mass and muscle strength in participants from the SarcoPhAge cohort, consisting of community-dwelling older adults. The malnutrition status was assessed at baseline (T0) according to the “Global Leadership Initiatives on Malnutrition” (GLIM) criteria, and the muscle parameters were evaluated both at T0 and after five years of follow-up (T5). Lean mass, muscle strength and physical performance were assessed using dual X-ray absorptiometry, handgrip dynamometry, the short physical performance battery test and the timed up and go test, respectively. Differences in muscle outcomes according to nutritional status were tested using Student’s t-test. The association between malnutrition and the relative 5-year change in the muscle parameters was tested using multiple linear regressions adjusted for several covariates. A total of 411 participants (mean age of 72.3 ± 6.1 years, 56% women) were included. Of them, 96 individuals (23%) were diagnosed with malnutrition at baseline. Their muscle parameters were significantly lower than those of the well-nourished patients both at baseline and after five years of follow-up (all p-values < 0.05), except for muscle strength in women at T5, which was not significantly lower in the presence of malnutrition. However, the 5-year changes in muscle parameters of malnourished individuals were not significantly different than those of well-nourished individuals (all p-values > 0.05).

Community Dwelling Older Adults

Abstract Background Aging is associated with reduced muscle mass and strength leading to impaired physical function. Resistance training programs incorporated into older adults’ real-life settings may have the potential to counteract these changes. We evaluated the effectiveness of 8 months resistance training using easily available, low cost equipment compared to physical activity counselling on physical function, muscle strength, and body composition in community-dwelling older adults receiving home care. Methods This open label, two-armed, parallel group, cluster randomized trial recruited older adults above 70 years (median age 86.0 (Interquartile range 80–90) years) receiving home care. Participants were randomized at cluster level to the resistance training group (RTG) or the control group (CG). The RTG trained twice a week while the CG were informed about the national recommendations for physical activity and received a motivational talk every 6th week. Outcomes were assessed at participant level at baseline, after four, and 8 months and included tests of physical function (chair rise, 8 ft-up-and-go, preferred- and maximal gait speed, and stair climb), maximal strength, rate of force development, and body composition. Results Twelve clusters were allocated to RTG (7 clusters, 60 participants) or CG (5 clusters, 44 participants). The number of participants analyzed was 56–64 (6–7 clusters) in RTG and 20–42 (5 clusters) in CG. After 8 months, multilevel linear mixed models showed that RTG improved in all tests of physical function and maximal leg strength (9–24%, p = 0.01–0.03) compared to CG. No effects were seen for rate of force development or body composition. Conclusion This study show that resistance training using easily available, low cost equipment is more effective than physical activity counselling for improving physical function and maximal strength in community-dwelling older adults receiving home care.

Abstract Context: High vitamin D and physical activity (PA) levels are independently associated with improved body composition and muscle function in older adults. Objective: The objective of this study was to investigate the interaction of 25-hydroxyvitamin D (25OHD) and PA status in maintenance of body composition and muscle function in older adults. Design and Setting: This was a 5-year prospective population-based study of Australian community-dwelling older adults. Participants: Participants in the study included 615 community-dwelling volunteers aged 50 years old or older [61.4 ± 6.9 (mean ± SD) y; 48% female] randomly selected from electoral rolls and categorized according to baseline serum 25OHD (≥ or &lt;50 nmol/L) and PA (≥ or &lt;10 000 pedometer determined steps/d) levels as follows: high 25OHD and high PA (VitD+PA+); high 25OHD and low PA (VitD+PA−); low 25OHD and high PA (VitD-PA+); and low 25OHD and low PA (VitD-PA−). A subset of 518 participants completed accelerometer assessments during follow-up. Main Outcome Measures: Changes in dual-energy X-ray absorptiometry-assessed body composition and lower-limb muscle function were measured. Results: VitD+PA+ had significantly smaller increases in body fat over 5 years compared with other groups (all P &lt; .05). Higher baseline pedometer-determined PA resulted in declines in total body fat (β = −.23 kg per 100 steps/d, P = .001) over 5 years for participants with high 25OHD but not those with low 25OHD (P &gt; .05). Among participants with accelerometer data, these associations were generally mediated by higher levels of moderate/vigorous PA. Conclusions: High vitamin D status appears to enhance PA-related declines in body fat during aging, but the mechanism may be greater amounts of outdoor moderate/vigorous PA rather than a direct effect of 25OHD.

Community Dwelling Older Adults

Background Despite the known health benefits of physical activity (PA), less than half and less than one-third of older adults in Germany reach the PA recommendations for endurance training and strength training, respectively, of the World Health Organization. The aim of this study is to investigate the implementation and effectiveness over the course of 9 months of two interventions (information technology [IT]-based vs print-based) for PA promotion among initially inactive older adults in a randomized, crossover trial. This study is part of a large research consortium (2015-2021) investigating different aspects of PA promotion. The IT-based intervention was previously developed and refined, while the print-based intervention was newly developed during this funding phase. Objective We aim to compare the effectiveness and examine the preferences of study participants regarding both delivery modes. Methods Our target sample size was 390 initially inactive community-dwelling older adults aged ≥60 years at baseline (3-month follow-up [T1]: expected n=300; 9-month follow-up [T2]: expected n=240) who were randomized to one of two interventions for self-monitoring PA: IT-based (50%) or print-based (50%) intervention. In addition, 30% of the IT-based intervention group received a PA tracker. At T1, participants in both groups could choose whether they prefered to keep their assigned intervention or cross over to the other group for the following 6 months (T2). Participants’ intervention preferences at baseline were collected retrospectively to run a post hoc matched-mismatched analysis. During the initial 3-month intervention period, both intervention groups were offered weekly group sessions that were continued monthly between T1 and T2. A self-administered questionnaire and 3D accelerometers were employed to assess changes in PA between baseline, T1, and T2. Adherence to PA recommendations, attendance at group sessions, and acceptance of the interventions were also tracked. Results The funding period started in February 2018 and ends in January 2021. We obtained institutional review board approval for the study from the Medical Association in Bremen on July 3, 2018. Data collection was completed on January 31, 2020, and data cleaning and analysis started in February 2020. We expect to publish the first results by the end of the funding period. Conclusions Strategies to promote active aging are of particular relevance in Germany, as 29% of the population is projected to be ≥65 years old by 2030. Regular PA is a key contributor to healthy aging. This study will provide insights into the acceptance and effectiveness of IT-based vs print-based interventions to promote PA in initially inactive individuals aged ≥60 years. Results obtained in this study will improve the existing evidence base on the effectiveness of community-based PA interventions in Germany and will inform efforts to anchor evidence-based PA interventions in community structures and organizations via an allocation of permanent health insurance funds.

Objective: The objective of this is to examine whether pain is associated with the onset of loneliness in a sample of community-dwelling older adults. Methods: We used data from the 2008 and 2012 Health and Retirement Study. We limited the sample to community-dwelling persons aged 60 years and over who were not lonely in 2008 in order to predict the risk of onset of loneliness (incidence) in 2012. Our analytic sample included 1,563 observations. Results: Approximately 31.7% of participants reported loneliness at follow-up (2012). Logistic regression models showed that the odds of loneliness onset was 1.58 higher for those with pain at both time points, compared with those who had pain at neither time point, even after controlling for other covariates. Discussion: The results indicate that pain may increase the risk of loneliness in older adults. This suggests that appropriate pain interventions could prevent future loneliness, which in turn could prevent functional decline, disability, and premature mortality.
