Abstract Background Zinc could be a target nutrient in the prevention of physical impairment and frailty in older adults due to its anti-inflammatory/antioxidant properties. However, prospective studies evaluating this inquiry are scarce. Thus, we aimed to assess the association between zinc intake and impaired lower-extremity function (ILEF) and frailty among community-dwelling older adults. Methods We examined 2,963 adults aged ≥60 years from the Seniors-ENRICA cohort. At baseline (2008–2010) and subsequent follow-up (2012), zinc intake (mg/d) was estimated with a validated computerized face-to-face diet history and adjusted for total energy intake. From 2012 to 2017, the occurrence of ILEF was ascertained with the Short Physical Performance Battery, and of frailty according to the Fried phenotype criteria. Analyses were conducted using Cox proportional hazard models adjusted for relevant confounders, including lifestyle, comorbidity, and dietary factors. Results During follow-up, we identified 515 incident cases of ILEF and 241 of frailty. Compared to participants in the lowest tertile of zinc intake (3.99–8.36 mg/d), those in the highest tertile (9.51–21.2 mg/d) had a lower risk of ILEF [fully-adjusted hazard ratio (95% confidence interval): 0.75 (0.58–0.97); p for trend: 0.03] and of frailty [0.63 (0.44–0.92); p for trend: 0.02]. No differences in the association were seen by strata of socio-demographic and lifestyle factors. Conclusions Higher zinc intake was prospectively associated with a lower risk of ILEF and frailty among older adults, suggesting that adequate zinc intake, that can be achieved through a healthy diet, may help preserve physical function and reduce the progression to frailty.

Abstract The present study aims to investigate poor olfaction in relation to physical functioning in community-dwelling older adults and potential sex and race disparities. The analysis included 2511 participants aged 71-82 years (51.7% women and 38.4% blacks) from the Health Aging, and Body Composition (Health ABC) study. Olfaction was tested with the 12-item Brief Smell Identification Test (BSIT). Physical function measures included the Short Physical Performance Battery (SPPB), the Health ABC Physical Performance Battery (HABCPPB), gait speed of 20-meter walk, fast 400-meter walking time, grip strength, and knee extensor strength, repeatedly assessed annually or biennially for a follow-up of seven years. We analyzed each of these physical function measures using mixed models, adjusting for demographics, lifestyle, and comorbidities. For all measures except grip and knee extensor strength, poor olfaction was clearly associated with poorer physical performance at baseline and a faster decline over time. For example, at baseline, the multivariate adjusted SPPB was 8.23 ± 0.09 for participants with poor olfaction and 8.55 ± 0.09 for those with good olfaction (P = 0.02), after seven years of follow-up, the corresponding scores decreased to 6.46 ± 0.12 and 7.36 ± 0.10 respectively (cross-sectional P<0.001, and P for olfaction-by-year interaction < 0.001). For grip and knee extensor strength, similar differences were suggested but didn’t reach statistical significance. The overall results were similar by sex and race. In summary, poor olfaction is clearly associated with faster decline in physical functioning in older adults and future studies should investigate its potential health implications.

ObjectiveTo assess the relationship of serum brain-derived neurotrophic factor (BDNF) levels with the subsequent short-term decline in cognitive functioning in community-dwelling older adults.DesignTwo-year prospective, observational study.Setting and ParticipantsThe study included 405 adults aged 65–84 years, initially free of a dementia diagnosis who were living in Tokyo, Japan.MethodsParticipants underwent health assessments at baseline (2011) and follow-up (2013). Serum BDNF levels and scores from the Montreal Cognitive Assessment-Japanese version (MoCA-J) were systematically measured. Logistic regression was used to estimate the odds of cognitive decline between baseline and follow-up assessments in the full MoCA-J scale (operationally defined as a decrease of two or more points), as well as in MoCA-J subscales (decline of one or more points in a specific subscale), as a function of serum BDNF level, adjusting for baseline demographics, prevalent chronic diseases, and baseline cognitive scores.ResultsAmong individuals who performed worse on the full MoCA-J at baseline (i.e., scores in the bottom quartile [≤21], which is consistent with a mild cognitive impairment status), but not among those who performed better (top 3 quartiles), those with highest baseline serum BDNF levels (top quartile) had lower odds of subsequent decline in the full MoCA-J scale than those with lowest (bottom quartile); i.e., odds ratio (OR): 0.10 (95% confidence interval [CI]: 0.02–0.62; p = 0.013). Regarding MoCA-J subscales, adjusted odds of decline in the executive function subscale, but not in the other five subscales, were substantially low among those with highest baseline serum BDNF levels (top quartile), as compared to those with the lowest (bottom quartile), i.e., OR: 0.27 (95% CI:0.13–0.60; p < 0.001).Conclusion and ImplicationsHigher serum BDNF levels were associated with a lower risk of decline in cognitive function in a sample of community-dwelling older Japanese adults. Risk varied across cognitive subdomains and according to baseline cognition. This warrants further research to evaluate the added-value of serum BDNF in health promotion initiatives directed toward cognitive decline prevention in community-dwelling older adults.

Abstract Background Although a few studies reported an association between varicose veins and physical function, this potentially bi-directional association has not been systematically evaluated in the general population. Methods In 5,580 participants (aged 71-90 years) from the Atherosclerosis Risk in Communities study, varicose veins were identified in outpatient and inpatient administrative data prior to (prevalent cases) and after (incident cases) visit 5 (2011-2013). Physical function was evaluated by the Short Physical Performance Battery (SPPB, score ranging from 0-12). We evaluated 1) cross-sectional association between prevalent varicose veins and physical function, 2) association of prevalent varicose veins with subsequent changes in physical function from visit 5 to visits 6 (2016-2017) and 7 (2018-2019), 3) association of physical function at visit 5 with incident varicose veins during a median follow-up of 3.6 years (105 incident varicose veins among 5,350 participants without prevalent cases at baseline). Results At baseline, varicose veins were recognized in 230 (4.1%) participants and cross-sectionally associated with reduced physical function. Longitudinally, prevalent varicose veins were not significantly associated with a decline in SPPB over time. In contrast, a low SPPB ≤6 was associated with a greater incidence of varicose veins compared to SPPB ≥10 (adjusted hazard ratio 2.13 [95% CI 1.19, 3.81]) . Conclusion In community-dwelling older adults, varicose veins and low physical function were associated cross-sectionally. Longitudinally, low physical function was a risk factor for incident varicose veins, but not vice versa. Our findings suggest an etiological contribution of low physical function to incident varicose veins.

Abstract Background: There are limited longitudinal data regarding nutrient intake, nutritional status and physical function in community-dwelling ethnically diverse older adults. This study explored these variables and their relationship at baseline (n=100) and 8-months’ follow-up (n=81) among community-dwelling ethnically diverse older adults (≥60 years) in Birmingham, United Kingdom. Methods: Multiple-pass 24-hour dietary recalls and the Mini Nutritional Assessment-Short Form assessed nutritional intake and status, respectively. Short Physical Performance Battery (SPPB) and handgrip strength measured physical function. Linear and multinomial regressions were used to predict relationships between physical function, nutritional status and nutrient intake. Results: Complete data were collected at baseline (n=100) and 8-months’ follow-up (n=81). Mean (SD) age was 70 (8.1) years (60% male), with 62% being obese. Statistically significant decreases in intakes of vitamin B6, vitamin B1, iron, folate, and magnesium occurred over time. Daily intake of all micronutrients except vitamin B12, phosphorus and manganese were below the Recommended Nutrient Intakes (RNI). SPPB (Z=-4.01, p<0.001) and nutritional status (Z=-2.37, p=0.018) declined over time. Higher SPPB scores at baseline (OR=0.54 95% CI 0.35, 0.81) were associated with a slower decline in nutritional status. Conclusion: The observed declines and inadequate nutrient intakes in the absence of weight loss in just eight months may pose serious challenges to healthy ageing, identifying an urgent need to re-evaluate and tailor appropriate dietary advice for this population. Additionally, the associations of nutrition and physical function observed in this study serves as an essential resource to design and implement community/faith-based interventions targeting early screening of nutritional status and physical function to ensure most older adults are assessed and treated accordingly.

Abstract Background The effects of group exercise on the physical function of community-dwelling older adults remain unclear. The changes in lower extremity muscle strength, timed up and go (TUG) time, and the motor fitness scale (MFS), over time, among older adults who expressed a willingness to participate in community-based physical exercise groups, were determined using multilevel modelling. Methods We analyzed data of 2407 older adults between April 2010 and December 2019 from the registry of physical tests of community-based physical exercise groups. We conducted a retrospective cohort study to assess the effect of physical exercise on lower extremity muscle strength, TUG time, and MFS scores. The durations of the exercises were evaluated by frequency of physical test’s participate. Results A deterioration in lower extremity muscle strength was found in the short-term participant group only. However, in the mid-term and long-term participation groups, lower extremity muscle strength showed a trend of improvement. The TUG time and the MFS score were negatively correlated with increasing age in both groups divided by the duration of participation. However, there was a slower rate of deterioration in the long-term participation group. Discussion Lower extremity muscle strength, TUG time, and MFS scores decline with increasing age and there were differences in the slope of deterioration that depended on the duration of participation in community-based group exercise. Conclusion Participation in group exercise improved lower extremity muscle strength, TUG time, and MFS scores of older adults living in a community. The positive effects of group exercise were dependent on long-term participation.

A meta-analysis of the efficacy of forgiveness interventions in older adults was conducted. International databases (Medline, PsycINFO, Scopus, Web of Science) were searched for studies published from 1990 to 2020 that attempted to promote forgiveness in older adults. Most intervention studies are group treatments targeted towards community-dwelling older adults. Participants in these studies are mainly women. The intervention objectives and contents vary widely and often criteria are not well-defined. Participants that received forgiveness interventions reported significantly higher levels of forgiveness than participants that did not receive treatment. Additionally, forgiveness interventions resulted in more changes in depression, stress and anger than no intervention conditions. Forgiveness treatment also enhances positive states (satisfaction with life, subjective happiness, and psychological wellbeing). The reported effects are moderate. The specific treatment model (e.g., Enright’s, Worthington’s) and format (e.g., group-based interventions and individually delivered programs) do not differentially predict better outcomes. In conclusion, future intervention studies should include more male participants and utilize a broader range of follow-up periods. Caution must be exercised because of the limited number of studies developed to date; researchers must be cautious when generalizing the results.

Abstract Background We aimed to determine the effectiveness of 4 weeks of balance exercise compared with no intervention on objectively measured postural sway. Methods This was a single-center parallel randomized controlled, open label, trial. A six-sided dice was used for allocation at a 1:1-ratio between exercise and control. The trial was performed at a university hospital clinic in Sweden and recruited community-dwelling older adults with documented postural instability. The intervention consisted of progressively challenging balance exercise three times per week, during 4 weeks, with follow-up at week five. Main outcome measures were objective postural sway length during eyes open and eyes closed conditions. Results Sixty-five participants aged 70 years (balance exercise n = 32; no intervention n = 33) were randomized. 14 participants were excluded from analysis because of early dropout before follow-up at week five, leaving 51 (n = 22; n = 29) participants for analysis. No significant differences were detected between the groups in any of the postural sway outcomes. Within-group analyses showed significant improvements in hand grip strength for the intervention group, while Timed Up & Go improvements were comparable between groups but only statistically significant in the control group. Conclusions Performing balance exercise over a four-week intervention period did not acutely improve postural sway in balance-deficient older adults. The lower limit in duration and frequency to achieve positive effects remains unclear. Trial registration Clinical trials NCT03227666, July 24, 2017, retrospectively registered.

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).
