Few studies have measured the activity patterns of continuing care residents using objective, uniaxial, accelerometers such as the activPAL. This exploratory study described the activity performance of continuing care residents and explored the correlation of activity performance with grip strength, falls and mobility. Data were gathered from 24 continuing care residents. Participants (82.3 ± 5.8 years of age), wore the activPAL an average of 12.60 hours per day (SD = 0.96) and were stepping for a median of 0.47 hours (25th and 75th percentiles = 0.31, 0.81) with a median step count of 1906 steps (25th and 75th percentiles = 1216, 3420). Participants were inactive (sitting/lying/standing) for a mean 11.99 hours (SD = 1.03). No statistically significant correlations were identified between activity performance (active time, inactive time or step count) and grip strength, falls or mobility. Ambulatory older adults in continuing care centres were more sedentary compared to community-dwelling older adults or older adults with cancer.

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.

The aim of this study was to identify questions that could estimate grip strength. Twenty-six questions about the degree of perceived difficulty performing manual tasks as well as two questions concerning self-rated grip strength were developed and completed by 123 community-dwelling older adults, followed by grip strength measurements using a Martin vigorimeter. Multiple regression analyses with all of the participants revealed that the question about the difficulty of opening a jar (question 4) was most associated with grip strength. When analyses were done by gender, the same question showed the best correlation for women, whereas the one for men was self-rated grip strength compared with people the same age (question 28). For the women, age and question 4 together explained 54% of the variance in their grip strength and for the men, age and question 28 explained 46%. Further studies are needed to identify other information that could help to better estimate grip strength for use in epidemiological surveys.

OBJECTIVE: To evaluate the relationship between respiratory muscle strength and grip strength in institutionalized and community-dwelling older adults. METHODS: This cross-sectional study had 64 voluntary participants, and 33 were institutionalized and 31 lived in the community. Maximal inspiratory pressure, maximal expiratory pressure, peak expiratory flow, grip strength, anthropometric data, and physical activity level were assessed. RESULTS: In the institutionalized group, there was no correlation between respiratory variables and grip strength, but maximal expiratory pressure was the respiratory predictor most strongly associated with grip strength (p = 0.04). In the community-dwelling group, there was a correlation between maximal inspiratory pressure and grip strength (r = 0.54), maximal expiratory pressure and grip strength (r = 0.62), and peak expiratory flow and grip strength (r = 0.64); peak expiratory flow and maximal expiratory pressure were the respiratory predictors most strongly associated with grip strength (p < 0.05). In a joint group analysis, there was an association between maximal inspiratory pressure and grip strength (r = 0.40), maximal expiratory pressure and grip strength (r = 0.57), and peak expiratory flow and grip strength (r = 0.57); peak expiratory flow and maximal expiratory pressure were the respiratory predictors most strongly associated with grip strength (p < 0.05). CONCLUSIONS: Peak expiratory flow and maximal expiratory pressure seem to be good predictors of grip strength in community-dwelling older adults, but this relationship does not seem to be maintained in institutionalized patients, possibly because of a greater loss of respiratory function.

Abstract Introduction Physical activity (PA) is important for older people to maintain functional independence and healthy ageing. PA interventions for community-dwelling older adults are often delivered by healthcare professionals, fitness instructors or trained members of a research team. Innovative approaches are needed to ensure that these interventions are practical and sustainable. This systematic review explores the effectiveness of volunteer-led PA interventions in improving health outcomes for community-dwelling older people. Methods Following PRISMA recommendations, five databases (MEDLINE, Embase, CINAHL, PEDro, Cochrane library) were systematically searched until May 2019, for studies using trained volunteers to deliver PA interventions for community-dwelling older people aged ≥ 65 years, reporting on participant outcomes. Meta-analysis was not conducted due to included study heterogeneity. Results Twelve papers (eight studies including three randomised controlled trials (RCTs)) were included in the review; five papers reported different outcomes from the same RCT. Intervention settings included community exercise groups (n=4), home (n=2) and care homes (n=2). All eight studies included strength and balance exercises and frequency of PA ranged from once daily to weekly sessions. The three RCTs showed improvement in grip strength, nutritional and frailty status, and reduction in fear of falling, among 39 older adults (mean age 83 years) who received a physical training and nutritional intervention; improvement in grip strength and activity of daily living scores among 56 nursing home older adults (mean age 78 years) who received resistance exercise training; and a significantly higher proportion of older adults (n = 193, 9% improvement vs 0.5% in the control group) achieved the recommended target of 150 minutes of moderate vigorous PA per week using the Falls Management Exercise intervention. Two studies compared volunteer and health professional-delivered PA interventions and reported that both interventions were equally effective in reducing fear of falls and improving quality of life. Two quasi-experimental studies reported improvement in functional outcomes including functional reach, timed up and go test, and chair stand. A large prospective cohort study (n = 1620) reported a reduction in disability among older adults who received volunteer-led exercise compared to control, with a hazard ratio of 0.73 (95% CI 0.62-0.86) for development of disability. Conclusions Trained volunteers can lead PA interventions among community-dwelling older adults with some evidence of improved health outcomes including nutritional, functional and frailty status.
