Time Effects on Physical Performance in Older Adults in Nursing Home: A Narrative Review

Maintaining daily living activities in older adults: The impact of a functional exercise program in long-term nursing homes. A single-group pre-post intervention

OBJECTIVE

To evaluate the impact of a function-focused multicomponent exercise program on long-term nursing home (LTNH) residents' ability to maintain activities of daily living (ADL), physical performance, cognitive function, quality of life, and frailty.

METHODS

This multicenter single-group pre-post quasi-experimental study involved 148 participants from 16 LTNHs in Gipuzkoa, Spain. Participants underwent a twice-weekly, 6-month function-focused multicomponent exercise program and were assessed both before and after the intervention.

RESULTS

Following the intervention, participants significantly maintained ADL ability, improved physical performance and quality of life, and reduced frailty (all p < 0.05). Cognitive function showed a positive trend. Subgroup analysis showed consistent improvements across demographics and health variables.

CONCLUSIONS

The exercise program effectively maintained or improved ability to perform ADL, cognitive function, physical performance, and quality of life while reducing frailty in LTNH residents, irrespective of individual characteristics. This highlights the importance of exercise interventions to preserve overall function and wellbeing in this population.

Effect of Comprehensive Balance Modulating Strategies on Physical Performance Among the Elderly in Care Home Settings in Southern India

Purpose Globally, the proportion of the elderly population is rising. Age-related physical performance impairments are more common and affect quality of life. This study aimed to investigate the impact of a new exercise regimen called Comprehensive Balance-Modulating Strategies (CBMS) on the physical performance of older adults living in care home settings. Methods Forty-eight functionally independent elderly individuals were randomized into two groups: group A received the CBMS programme for eight weeks, and group B received routine medical care. The Short Physical Performance Battery (SPPB) and the Four Square Step Test (FSST) were outcome measures. Outcomes were measured at baseline, immediately after the intervention, and eight weeks after the intervention. Results The mean and standard deviation of subjects' ages in both groups were 72.46 (8.28) and 68.12 (6.95), respectively. The CBMS programme significantly improved physical performance among the intervention group (p = <0.0001). Conclusion The present study found that CBMS was effective in improving physical performance among institutionalized elderly. Large-scale clinical trials and research exploring the effect of CBMS among community-dwelling elderly individuals are recommended.

The effect of Otago exercises on fear of falling, balance, empowerment and functional mobility in the older people: Randomized controlled trial

AIM

This study aimed to test the effect of Otago exercises on fear of falling, balance, empowerment and functional mobility in older people living in nursing homes.

METHODS

This study is a parallel-group randomized controlled trial. In total, 56 individuals were stratified randomized according to age-gender. Participants were recruited from September 2021 to August 2022. Data were collected at baseline, in the 8th and 12th weeks. The researcher gave Otago exercise training to the intervention group three times per week for the first 4 weeks and applied it to the individuals, and in the next 8 weeks, the researcher visited the institution to ensure the continuity of the exercises and contacted the individuals by phone. Friedman test and generalized linear model were used in the analysis of data.

RESULTS

In the study, group and time interaction were found to be significant in terms of the Berg balance scale, 30-second sit-and-stand test, elderly empowerment scale and timed up-and-go test. It was determined that the intervention did not improve fear of falling, upper extremity strength and 6-min walk test results.

CONCLUSION

Health personnel and administrators should have increased awareness about Otago exercises and can recommend implementation of the programme.

Risk factors for inpatient facility admission among home health care patients with diabetes

BACKGROUND

Home health care (HHC) patients with diabetes are at high risk for inpatient admissions.

PURPOSE

To identify variables associated with inpatient admissions among adults age ≥50 with diabetes receiving HHC in the community and in assisted living (AL).

METHODS

Retrospective HHC data (collected October 2021 to March 2022 in the Southern United States) from the Outcome and Assessment Information Set D were analyzed with logistic regression (n = 5,308 patients).

DISCUSSION

The inpatient admission rate was 29.5%. For community-dwelling patients, multiple hospitalizations, depression, limited cognitive function, decreased activities of daily living (ADL) performance, and unhealed pressure ulcer or injury ≥stage 2 were significantly associated with inpatient admission. For those in AL, multiple prior hospitalizations and decreased ability to perform ADLs were associated with inpatient admission.

CONCLUSION

Understanding risk factors for inpatient admissions among patients with diabetes can support the identification of at-risk patients and inform interventions.

Implementation of interventions to maintain and promote the functional mobility of nursing home residents - a scoping review

BACKGROUND

To provide an overview of the available evidence on the implementation of direct and capacity-building interventions to promote and maintain the functional mobility of nursing home residents.

METHODS

We conducted a scoping review following the methodological guidance for the conduct of scoping reviews as described by the Joanna Briggs Institute. We searched for studies in MEDLINE (via PubMed) and CINAHL (via EBSCO). We conducted a qualitative content analysis of the included studies with deductive categories based on the Consolidated Framework for Implementation Research (CFIR).

RESULTS

Ultimately, we included 8 studies on direct interventions, 6 studies on capacity-building interventions, and 2 studies on both types of interventions in our review. Seven studies provided evidence on implementation strategies comprising discrete as well as multifaceted, multilevel strategies. Most of the studies did not systematically evaluate the strategies but remained at a descriptive level. All 16 studies provided evidence of influencing factors. We identified 32 of the 37 influencing factors of the CFIR. The five most frequent influencing factors were available resources (n = 14), access to knowledge and information (n = 12), patient needs and resources (n = 10), knowledge and beliefs about the intervention (n = 10) and compatibility (n = 9).

CONCLUSIONS

The available evidence on the implementation of functional mobility interventions in nursing homes is rather limited. This emphasizes the need for further research. Regarding implementation strategies, the systematic evaluation and further development of the reported promising approaches might be a starting point.

Cognitive, physical and emotional determinants of activities of daily living in nursing home residents-a cross-sectional study within the PROCARE-project

BACKGROUND

Interdependencies of health, fitness, cognition, and emotion can promote or inhibit mobility. This study aimed to analyse pathways and interactions between individual subjective and objective physical performance, cognition, and emotions with activities of daily living (ADLs) as mobility indicators in multimorbid nursing home residents.

METHODS

The study included n = 448 (77.1% females, age = 84.1 ± 7.8 years) nursing home residents. To describe the participant's demographics, frailty, number of falls, and participating institutions' socioeconomic status (SES) were assessed. ADLs were measured with the Barthel Index (BI; dependent variable). Independent variables included objective physical performance, subjective physical performance, cognition, and emotions. A structural equation model (SEM) with maximum likelihood estimation was conducted with AMOS. Direct and indirect effects were estimated using standardized coefficients (significance level of 0.05).

RESULTS

Indices showed (Chi2(148) = 217, PCMIN/DF = 1.47; p < .001; Comparative Fit Index = .940; Tucker Lewes Index = .902, RMSEA = .033) that the model fitted the data adequately. While there was no direct association between emotions, subjective physical performance, and ADLs, objective physical performance and cognition predicted higher ADLs (p < .01). Emotions had a strong relationship with subjective physical performance, and cognition had a moderate relationship with objective physical performance.

DISCUSSION AND CONCLUSION

Objective performance and cognition predicted higher functional status, as expressed by higher BI scores. ADLs, such as mobility, dressing, or handling tasks, require motor and cognitive performance. Subjective performance is an important predictor of ADLs and is only partly explained by objective performance, but to a large extent also by emotions. Therefore, future interventions for nursing home residents should take a holistic approach that focuses not only on promoting objective physical and cognitive performance but also on emotions and perceived physical performance.

Effects of physical exercise on physical function in older adults in residential care: a systematic review and network meta-analysis of randomised controlled trials

BACKGROUND

Physical exercise is effective at attenuating ageing-related physical decline in general, but evidence of its benefits for older adults in residential care, who often have functional dependency, multimorbidity, and polypharmacy, is inconclusive. We aimed to establish the effects of exercise interventions on the physical function of this population.

METHODS

For this systematic review and network meta-analysis, we searched PubMed, Web of Science, Cochrane Library, Rehabilitation & Sports Medicine Source, and SPORTDiscus to identify randomised controlled trials assessing the effects of exercise interventions (vs usual care) on physical function (ie, functional independence, physical performance, and other related measures, such as muscle strength, balance, or flexibility) in adults aged 60 years or older living in residential care. Relevant studies published in English or Spanish up to Jan 12, 2023, were included in the systematic review. The quality of studies was assessed using the Tool for the Assessment of Study Quality and Reporting in Exercise (TESTEX) score. A network meta-analysis was performed for physical function-related outcomes reported in at least ten studies, with subanalyses for specific intervention (ie, exercise type, training volume, and study duration) and participant (eg, having cognitive impairment or dementia, pre-frail or frail status, and being functionally dependent) characteristics. The study protocol was registered on PROSPERO (CRD42021247809).

FINDINGS

147 studies (11 609 participants, with mean ages ranging from 67 years [SD 9] to 92 years [2]) were included in the systematic review, and were rated as having overall good quality (median TESTEX score 9 [range 3-14]). In the meta-analysis (including 105 studies, n=7759 participants), exercise interventions were associated with significantly improved overall physical function, with a standardised mean difference [SMD] of 0·13 (95% credible interval [CrI] 0·04-0·21), which was confirmed in all analysed subpopulations. The strongest association was observed with 110-225 min per week of exercise, and the greatest improvements were observed with 170 min per week (SMD 0·36 [95% CrI 0·20-0·52]). No significant differences were found between exercise types. Subanalyses showed significant improvements for almost all analysed physical function-related outcomes (Barthel index, five-times sit-to-stand test, 30-s sit-to-stand test, knee extension, hand grip strength, bicep curl strength, Short Physical Performance Battery, 6-min walking test, walking speed, Berg balance scale, and sit-and-reach test). Large heterogeneity was found between and within studies in terms of population and intervention characteristics.

INTERPRETATION

Exercise interventions are associated with improved physical function in older adults in residential care, and should, therefore, be routinely promoted in long-term care facilities.

FUNDING

None.

The effect of horticultural therapy on older adults in pension institutions: a systematic review

AIMS

To systematically evaluate the effect of horticultural therapy (HT) on older adults in pension institutions.

DESIGN

Systematic review was conducted based on the checklist for PRISMA.

METHODS

The searches were conducted in the Cochrane library, Embase, Web of Science, PubMed, Chinese Biomedical Database (CBM), and the China Network Knowledge Infrastructure (CNKI), from their inception until May 2022. In addition, manual screening of references of relevant studies was performed to identify potential studies. We conducted a review of quantitative studies published in Chinese or English. Experimental studies were evaluated using the Physiotherapy Evidence Database (PEDro) Scale.

RESULTS

A total of 21 studies involving 1214 participants were included in this review, and the quality of the literature was good. Sixteen studies were Structured HT. The effects of HT were significant in terms of physical, physiological, and psychological aspects. In addition, HT improved satisfaction, quality of life, cognition, and social relationships, and no negative events were found.

CONCLUSION

As an affordable non-pharmacological intervention with a wide range of effects, horticultural therapy is suitable for older adults in pension institutions and is worth promoting in pension institutions, communities, homes, hospitals, and other institutions that require long-term care.

Exercise Guidelines to Counteract Physical Deconditioning in Long-Term Care Facilities: What to Do and How to Do It?

With age, older adults experience a decrease in muscle function and changes in body composition, which raise the risk of functional incapacity and loss of autonomy. These declines are more pronounced in older adults living in long-term care (LTC) facilities than those living in the community (ie, sarcopenia prevalence: ∼41% vs ∼10%; obesity prevalence: 30% vs17%). The main cause of these declines is chronic diseases, which are a driver of higher rates of sedentary behavior (85% of time in LTC). Exercise, however, is recognized to help counteract age-related decline, yet it is not integrated into clinical practice.

Efficacy of therapeutic exercise on activities of daily living and cognitive function among older residents in long-term care facilities: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVES

This study aimed to systematically analyze the efficacy of therapeutic exercise on activities of daily living (ADL) and cognitive function among older residents in long-term care facilities.

DATA SOURCES

PubMed, Cochrane Central of Register Trials, Physiotherapy Evidence Database, OTseeker, and Ichushi-Web were searched from inception until December 2018.

STUDY SELECTION

Databases were searched to identify randomized controlled trials (RCTs) of therapeutic exercise for long-term care facility residents aged 60 years and older, focusing on ADL and cognitive function as outcomes.

DATA EXTRACTION

Two independent reviewers extracted the key information from each eligible study. Two reviewers independently screened and assessed all studies for eligibility, extracting information on study participants, details of interventions, outcome characteristics, and significant outcomes. Any discrepancies were resolved by a third reviewer.

DATA SYNTHESIS

A total of 11 RCTs with 1,280 participants were eligible for analyses. Therapeutic exercise had a significant benefit on ADL (standard mean difference [SMD] = 0. 22, 95% confidence interval [CI]: 0.02, 0.42, p = 0.03)]. Subgroup analyses indicated that interventions were conducted ≥ 3 days per week [SMD = 0.42, 95% CI 0.02, 0.82, p = 0.04]. For cognitive function, group exercise and ≥ 3 days/week of intervention had a significant benefit (group exercise: mean difference [MD] = 3.36, 95% CI 0.91, 5.80, p = 0.007; ≥ 3 days/week of intervention: MD = 2.28, 95% CI 0.07, 4.49, p = 0.04).

CONCLUSIONS

Therapeutic exercise conducted 3 or more days per week may be effective for improving ADL and cognitive function among older residents in long-term care facilities. This meta-analysis suggested that group exercise for cognitive functions was effective. However, the effective method of intervention delivery for ADL was unclear.

Evaluation of the instrumented Timed Up and Go test as a tool to measure exercise intervention effects in nursing home residents: results from a PROCARE substudy

Background and objectives

To achieve independence in activities of daily living, a certain level of functional ability is necessary. The instrumented Timed Up and Go (iTUG) test provides guidance for appropriate interventions, for example, when considering the subphases within the TUG. Therefore, we evaluated the iTUG as a tool to measure the effects of a multicomponent exercise intervention on the iTUG subphases in nursing home residents.

Methods

Fifty long-term nursing home residents (34 women, 82.7 ± 6.46 [65–91] years; 16 men, 78.6 ± 7.0 [62–90] years) performed the iTUG test before and after a 16-week intervention period (2 × 45–60 min/week). According to the attendance rates, participants were divided into three groups.

Results

The total iTUG duration decreased from baseline to posttest, F(2,46) = 3.50, p = 0.038, η2p = 0.132. We observed significant correlations between the attendance rates and the total iTUG duration (r(50) = 0.328, p = 0.010). However, we did not observe significant group × time interaction effects in the subphases. The Barthel Index moderated the effect between attendance rate and the total duration of the iTUG test, ΔR2 = 8.34%, F(1,44) = 4.69, p = 0.036, 95% CI [0.001, 0.027].

Conclusions

We confirmed the effectiveness of the iTUG as a tool to measure exercise intervention effects in nursing home residents, especially when participants exhibit high attendance rates. That said, mobility needs to be considered in a more differentiated way, taking into account parameters in the subphases to detect changes more sensitively and to derive recommendations in a more individualized way.

Requirements of a cognitive-motor spatial orientation training for nursing home residents: an iterative feasibility study

A sedentary lifestyle in nursing home residents is often accompanied with reduced life space mobility and in turn affects satisfaction with life. One of the reasons for this may be limited ability to find one’s way around the care facility and its environment. However, spatial orientation exercises might reduce these problems if they are integrated into an adequate cognitive-motor training. Therefore, we integrated six novel and target group-specific spatial orientation exercises into an established multicomponent cognitive-motor group training for nursing home residents and evaluated its feasibility. Forty nursing home residents (mean age: 87.3 ± 7 years) participated in the spatial orientation cognitive motor training (45–60 min, twice a week over a period of 12 weeks). The main outcomes included the feasibility criteria (adherence, completion time, acceptance, instructions, motor performance, materials/set up, complexity) and first measurements of mobility and satisfaction with life (SPPB [Short Physical Performance Battery], SWLS [Satisfaction with Life Scale]). Adherence increased over time. The increase was associated with the adaptions and modifications of the spatial orientation exercises that were made to meet the participants’ requirements. A positive trend was discerned for mobility and life satisfaction, comparing pre- and posttraining data. In summary, the feasibility analysis revealed that future interventions should consider that (a) instructions of demanding spatial tasks should be accompanied by an example task, (b) trainers should be encouraged to adjust task complexity and materials on an individual basis, (c) acceptance of the training should be promoted among nursing staff, and (d) surroundings with as little disturbance as possible should be selected for training.

Multicomponent exercise to improve motor functions, cognition and well-being for nursing home residents who are unable to walk - A randomized controlled trial

BACKGROUND

Older nursing home residents are often characterized by multimorbidity and dependency in activities of daily living. Most exercise studies in this setting aim at residents who are still able to walk despite the huge group of residents that is unable to walk. Thus, little is known about the effectiveness to improve cognitive and motor functions as well as well-being within this target group, e.g., by use of chair-based exercises. The aim of this study was to determine the effects of a 16-week multicomponent chair-based exercise intervention on motor functions, cognition and well-being for nursing home residents who are unable to walk.

METHODS

A two-arm single-blinded multicenter randomized controlled trial integrated N = 52 nursing home residents with a mean age of 81 ± 11 years (63% female), randomly assigned to a training (n = 26, 16 weeks; twice a week; 60 min) or a wait-list control group (n = 26). The intervention followed the F.I.T.T. principles (frequency, intensity, time and type) and was continuously adapted to residents' performance level. The outcomes motor function (hand grip strength, sitting balance, manual dexterity), cognitive performance (cognitive status, working memory) and psychosocial resources (physical and mental well-being (SF12), satisfaction with life (SWLS), depressive symptoms (CES-D)) were assessed at baseline (pre-test) and after 16-weeks (post-treatment). Statistics were performed using ANOVA for repeated measures.

RESULTS

The results of the ANOVA showed significant improvements of the intervention group for hand grip strength (Pre: M = 12.67, SD = 5.28; Post: M = 13.86, SD = 4.79; Group × Time: F(1, 17) = 10.816, p = .002, η_p² = 0.241), manual dexterity (Pre: M = 4.50, SD = 5.17; Post: M = 5.30, SD = 4.25; Group × Time: F(1, 7) = 9.193, p = .008, η_p² = 0.365), cognition (Pre: M = 10.31, SD = 6.87; Post: M = 11.06, SD = 7.50; Group × Time: F(1, 15) = 12.687, p = .001, η_p² = 0.284), and depression (Pre: M = 5.19, SD = 5.12; Post: M = 4.38, SD = 4.62; Group × Time: F(1, 14) = 5.135, p = .031, η_p² = 0.150) while the values of the control group decreased.

CONCLUSION

The multicomponent chair-based intervention over 16 weeks was able to improve motor functions and cognition in nursing home residents who are unable to walk. Other psychological factors remained stable within the intervention group, which can be interpreted as a good result for this target group. All of the investigated parameters showed a significant decrease in the control group. The intervention seemed to cause physiological adaptations even in very old age. Study results encourage to further differentiate the heterogeneous group of nursing home residents concerning mobility aspects and to include chair-based interventions as feasible program to prevent further decline of functional performance and maintain independence in activities of daily living for a better physical and mental well-being.

Can cognitive-motor training improve physical functioning and psychosocial wellbeing in nursing home residents? A randomized controlled feasibility study as part of the PROCARE project

BACKGROUND

A multi-component training program holds promises for the elderly, but still has to be tested on its feasibility and effect in nursing homes.

AIMS

The aim of this study was (1) to design a multi-component training program which improves physical functioning and psychosocial wellbeing and (2) to evaluate the feasibility of this intervention in nursing home residents.

METHODS

This study is a two-arm, stratified-randomized controlled feasibility trail. Twenty-four nursing home residents (aged 83.7 ± 6.4, 21 women) were divided into an intervention and a waiting-list control group. The intervention group completed a multi-component training (including dual-task, dynamic balance, endurance and strength exercises) for 16 weeks (twice per week for 45-60 min). Primary outcomes were lower extremity functionality (SPPB), gait performance (GAITRite), health-related quality of life (SF-12) as well as life satisfaction (SWLS).

RESULTS

Life satisfaction (SWLS) and physical functioning (SPPB) increased in the intervention group after training whereas the control group showed a decrease. Gait parameters could only be analyzed for n = 5 participants of the intervention group and n = 2 of the control group and showed no time differences for the intervention group. The mean number of participants was 12.5 ± 1.9 per session (attendance ranged between 66% and 90%).

CONCLUSION

A multi-component training seems (1) to lead to clinically relevant improvements in physical functioning as well as in psychosocial wellbeing and (2) to be feasible and well accepted in nursing home residents. Nevertheless, the complexity and progression of the program as well as the testing protocol have to be adapted. Further research should test the effectiveness of this adapted program in a larger sample size.

Trajectories of physical performance in nursing home residents with dementia

Background

In nursing homes (NH) the prevalence of dementia ranges from 50 to 84% and most residents have extensive physical-performance impairments. However, from time of admission, development of physical performance in NH residents with dementia remains unexplored.

Aims

To explore the overall trend in physical performance, associated characteristics, and groups following distinct trajectories from time of admission, in NH residents with dementia.

Methods

We followed newly admitted NH residents diagnosed with dementia (N = 583) from 47 NHs across Norway for 3 years. Individual assessments were conducted biannually, and main outcome measure was the Short Physical Performance Battery (SPPB). Facility-level characteristics included unit size, staff-to-resident ratio, and quality of the physical environment (Special Care Unit Environmental Quality Scale, SCUEQS).

Results

From time of admission, NH residents with dementia showed a significant overall decline in physical performance. Further, we identified three distinct trajectory groups with significantly different baseline physical-performance status (“good,” “moderate,” and “poor”), differences between groups maintained and all declined across time. Younger age, good general medical health, less-severe dementia, and less musculoskeletal pain were associated with both an average higher overall trend and better baseline group-belonging. Additionally, less apathy and more psychosis were associated with a higher overall trend, and agitation was associated with poorer baseline group-belonging.

Conclusions

To prevent excessive decline in physical performance in this population, NH clinicians should focus efforts specifically on assessment of physical performance at admission and on identification and management of musculoskeletal pain and neuropsychiatric symptoms.

Chair-Based Exercise Interventions for Nursing Home Residents: A Systematic Review

OBJECTIVES

Despite mobility impairments, many residents have physical, cognitive, and psychosocial resources that should be promoted. The aim was to summarize the current evidence on chair-based exercise (CBE) interventions for nursing home residents.

DESIGN

Systematic review registered with Prospero (registration number: CRD42018078196).

SETTING AND PARTICIPANTS

Nursing home residents in long-term care.

METHODS

Five electronic databases were searched (MEDLINE, Embase, CINAHL, Cochrane Central, and PsycINFO) from inception until July 2020. Title, abstract, and full-text screening as well as quality assessment with the Downs and Black checklist was done by 2 independent reviewers. Studies were eligible if they (1) were conducted in nursing home residents, (2) included participants with a mean age of 65 years, (3) had at least 1 treatment arm with seated exercises only, (4) included active or inactive controls, (5) measured outcomes related to physical and/or cognitive functioning and/or well-being, and (6) controlled studies or single-group pre-post design. Because of a heterogeneity in characteristics of included studies, we refrained from conducting a meta-analysis.

RESULTS

Ten studies met the inclusion criteria (n = 511, mean age 79 ± 7 years, 65% female). Studies differed in sample size (12-114) as well as in training type (multicomponent, Yoga/Qigong/breathing exercise, range of motion) and dose (frequency 2 sessions/week to daily, intensity low to moderate, time 20-60 minutes/session, 6 weeks to 6 months). Overall, CBE appears to be feasible and safe. Studies found task-specific improvements in physical and cognitive functions and enhanced well-being. Three studies demonstrated improved lower body performance following a multicomponent CBE program in mobile residents. Three studies only including residents unable to walk reported improved physical functions, indicating that immobile residents benefit from CBE programs. There was a lack of separating mobile and immobile residents in analyses.

CONCLUSIONS AND IMPLICATIONS

The results indicate that CBE interventions may improve physical and cognitive functions as well as well-being in nursing home residents. Task-specific multicomponent CBE appears to be best for improving different domains of physical and cognitive functioning. More high-quality trials are needed.

Physical performance trajectories and mortality among nursing home residents: results of the SENIOR cohort

BACKGROUND

Previous studies have shown that older people can experience a considerable change in their physical performance (PP) over time.

OBJECTIVES

To identify PP trajectories and their association with mortality among nursing home residents who were followed up for 3 years.

DESIGN

Three-year longitudinal observational study.

SETTING

Subjects of the SENIOR cohort.

SUBJECTS

Six hundred and four nursing home residents with a mean age of 82.9 ± 9.1 years.

METHODS

Baseline characteristics and the date of death were collected from the medical records. PP was assessed annually by the short physical performance battery (SPPB) test. Multiple imputations were performed to manage the missing data. PP trajectory groups were estimated using latent growth curve analysis. Cox proportional hazard regression models were applied to examine the risk of mortality according to the PP trajectory groups.

RESULTS

Three PP trajectory groups were identified: slow decline (N = 96), moderate decline (N = 234) and fast decline (N = 274). After adjustments for potential confounding variables and the baseline SPPB scores, the residents in the fast decline and moderate decline trajectory groups had an increased risk of mortality compared to those in the slow decline trajectory group, with hazard ratio values of 1.78 (95% confidence interval [CI] = 1.34-2.26) and 1.37 (95% CI = 1.10-1.66), respectively.

CONCLUSIONS

PP trajectories provide value-added information to baseline geriatric assessments and could be used for predicting 3-year mortality among nursing home residents. It may be important to regularly monitor the SPPB score and signal an alert when a fast decline in PP is detected in older people.

Is Physical Activity Associated With Physical Performance in Adults With Intellectual Disability?

Physical activity (PA) and sedentary behavior may contribute to physical function in adults with intellectual disability (ID). This study examined whether objectively measured PA and sedentary behavior levels are associated with physical performance in adults with ID. Fifty-eight adults with ID (29 women and 29 men, age 44 ± 14 years) underwent a measurement of physical performance with the Short Physical Performance Battery (SPPB) and PA and sedentary time using a hip-worn accelerometer (wGT3X-BT; ActiGraph, Pensacola, FL). Moderate PA and age were significantly associated with the SPPB score (r = .39 and .34, respectively; p < .01). A hierarchical-regression model with moderate PA and age as independent variables indicated that moderate PA was a significant predictor of SPPB (p < .001; R2 = .153), but age was not (p = .123; R2 change = .036). Overall, moderate PA was significantly associated with the SPPB score, even after accounting for age, in adults with ID.
