Self-perceptions of aging (SPA) is associated with various health-related outcomes, including physical performance. No previous study has investigated the potential predictive influence of SPA on physical performance among Swedish community-dwelling older adults. This was a cross-sectional study using a random sample of 153 Swedish community-dwelling individuals aged 70 and older. Multiple logistic regression analysis was performed, using the subscale “Attitude Towards Own Aging” of the Philadelphia Geriatric Center Morale Scale, as a measure of SPA. The Short Physical Performance Battery (SPPB) was dichotomized and used as the outcome variable. SPA was a significant predictor (OR = 1.546, CI = 1.066–2.243) of physical performance, adjusted for age, cognitive function, and life-space mobility. Further analyses revealed significant sex differences, with SPA not being included in the model for the men whilst it was still a significant predictor (OR = 1.689, CI = 1.031–2.765) of physical performance in the group of women. SPA plays a significant role in predicting physical performance among Swedish community-dwelling older adults. To further clarify this relationship and its consequences, future longitudinal research should focus on the relationship between SPA, physical performance, and fall risk.

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).

Abstract Background Growth differentiation factor 15 (GDF15) has been associated with several age-related disorders, but its associations with functional abilities in community-dwelling older adults are not well studied. Methods The study was a secondary analysis on 1096 community-dwelling older adults (aged 69 to 94 years) recruited from the Multidomain Alzheimer’s Preventive Trial. Plasma GDF15 was measured one year after participants’ enrolment. Annual data of physical performance (grip strength and short physical performance battery [SPPB]) and global cognitive functions (mini-mental state examination [MMSE] and a composite cognitive score) were measured for four years. Adjusted mixed-effects linear models were performed for cross-sectional and longitudinal association analyses. Results A higher GDF15 was cross-sectionally associated with a weaker grip strength (β = -1.1E-03, 95%CI [-2.0E-03, -1.5E-04]), a lower SPPB score (β = -3.1E-04, 95%CI [-5.4E-04, -9.0E-05]) and worse cognitive functions (β = -2.4E-04, 95%CI [-3.3E-04, -1.6E-04] for composite cognitive score; β = -4.0E-04, 95%CI [-6.4E-04, -1.6E-04] for MMSE). Participants with higher GDF15 demonstrated greater longitudinal declines in SPPB (β = -1.0E-04, 95%CI [-1.7E-04, -2.0E-05]) and composite cognitive score (β = -2.0E-05, 95%CI [-4.0E-05, -3.6E-06]). The optimal initial GDF15 cutoff values for identifying participants with minimal clinically significant decline after one year were 2189 pg/mL for SPPB (AUC: 0.580) and 2330 pg/mL for composite cognitive score (AUC: 0.587). Conclusions Plasma GDF15 is cross-sectionally and longitudinally associated with lower-limb physical performance and global cognitive function in older adults. Circulating GDF15 alone has limited capacity of discriminating older adults who will develop clinically significant functional declines.

Abstract Background Evaluating physical performance could facilitate dementia risk assessment. However, findings differ regarding which type of physical performance best predicts dementia. Objective The objective of this study was to examine the association between physical performance and incidence of dementia in Japanese community-dwelling older adults. Design This was a prospective study of community-dwelling older adults. Methods Of 14,313 invited individuals who were ≥ 65 years old, 5104 agreed to participate from 2011 to 2012, and 4086 (52% women; mean age = 72.0 years) met the criteria. Baseline assessments of the following physical performance indicators were obtained: grip strength, the Five-Times Sit-to-Stand Test, and the Timed “Up & Go” Test. The physical performance level in each test was categorized as C1 (highest), C2 (middle–high), C3 (middle–low), or C4 (lowest) on the basis of sex-stratified quartile values. Incident dementia status was obtained from medical records that were updated monthly. Results During follow-up (mean duration = 42.9 months), there were 243 incident cases of dementia (5.9%). Log-rank test results indicated that a lower physical performance level constituted a significant risk factor for dementia. After adjustment for covariates, Cox proportional hazards models (reference: highest physical performance level [C1]) demonstrated that the Five-Times Sit-to-Stand Test in the group with the lowest physical performance level (hazard ratio = 1.69; 95% CI = 1.10–2.59) was significantly associated with a risk of dementia. Likewise, the Timed “Up & Go” Test in the group with the lowest physical performance level (hazard ratio = 1.54; 95% CI = 1.01–2.35) was significantly associated with a risk of dementia. However, grip strength was not significantly associated with a risk of dementia. Limitations This study was limited by the use of medical record data. Conclusions A lower mobility-related physical performance level was associated with dementia risk. Dementia risk assessment should include an adequate evaluation of physical function.

Aging is a global public health concern. From the age of 50, muscle mass, muscle strength and physical performance tend to decline. Sarcopenia and frailty are frequent in community-dwelling older adults and are associated with negative outcomes such as physical disability and mortality. Therefore, the identification of therapeutic strategies to prevent and fight sarcopenia and frailty is of great interest. This systematic review aims to summarize the impact of nutritional interventions alone or combined with other treatment(s) in older community-dwelling adults on (1) the three indicators of sarcopenia, i.e., muscle mass, muscle strength and physical performance; and (2) the hospitalization and readmission rates. The literature search was performed on Medline and included studies published between January 2010 and June 2020. We included randomized controlled trials of nutritional intervention alone or combined with other treatment(s) in community-living subjects aged 65 or older. In total, 28 articles were retained in the final analysis. This systematic review highlights the importance of a multimodal approach, including at least a combined nutritional and exercise intervention, to improve muscle mass, muscle strength and physical performance, in community-dwelling older adults but especially in frail and sarcopenic subjects. Regarding hospitalization and readmission rate, data were limited and inconclusive. Future studies should continue to investigate the effects of such interventions in this population.

Abstract Background Cross-sectional studies linking the association between obesity and falls are limited and their results are somewhat conflicting. The inconsistent evidence between obesity and falls could be explained by the utilization of different measures of obesity including BMI, WC, waist hip ratio (WHR) and percentage body fat (%BF) in different studies. Aims To examine the prospective association between various measures of obesity and falls among community-dwelling older adults. Methods We utilized data from the wave 1 and wave 2 of the Malaysian Elder’s Longitudinal Research Study (MELoR). Basic demographic characteristics, medical history, lifestyle factors and falls history in preceding 12 months was recorded by computer assisted questionnaire in participant’s home while anthropometric measurements, body composition assessments and physical performance were collected at the hospital during a hospital check-up at baseline. The main exposure variables were increased body mass index (BMI), waist circumference (WC), waist hip ratio (WHR) and percentage body fat (%BF) and the main outcome was self-report falls in the preceding 12 months at time of follow-up. Results Among 746 participants at baseline and follow-up (mean age 68.9 ± 7.3 years, old, 56.7% women), 150(20.1%) individuals had ≥1 time of fall at follow-up. No differences in mean age and proportion of men and women among fallers and non-fallers. However, fallers were found to have higher WHR, lower percentage muscle mass and performed poorer in physical performance (p-value&lt;0.01). Of the four obesity indicators, higher WHR at baseline was associated with increased risk of fall 12 months later even after adjustment for all potential confounders (aOR= 2.01; 95%CI= 1.26-3.18). Conclusions In conclusion, our findings suggest that WHR is the measure of adiposity most likely to differentiate fallers from non-fallers prospectively. Future studies should evaluate the mechanisms underlying the increased risk of falls associated with increased WHR.
