[PMID: 39259962 PMCID: PMC11425027 DOI: 10.2196/59497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Revised: 05/27/2024] [Accepted: 07/16/2024] [Indexed: 09/13/2024] Open
Abstract
BACKGROUND Monitoring free-living physical activity (PA) through wearable devices enables the real-time assessment of activity features associated with health outcomes and provision of treatment recommendations and adjustments. The conclusions of studies on PA and health depend crucially on reliable statistical analyses of digital data. Data analytics, however, are challenging due to the various metrics adopted for measuring PA, different aims of studies, and complex temporal variations within variables. The application, interpretation, and appropriateness of these analytical tools have yet to be summarized. OBJECTIVE This research aimed to review studies that used analytical methods for analyzing PA monitored by accelerometers. Specifically, this review addressed three questions: (1) What metrics are used to describe an individual's free-living daily PA? (2) What are the current analytical tools for analyzing PA data, particularly under the aims of classification, association with health outcomes, and prediction of health events? and (3) What challenges exist in the analyses, and what recommendations for future research are suggested regarding the use of statistical methods in various research tasks? METHODS This scoping review was conducted following an existing framework to map research studies by exploring the information about PA. Three databases, PubMed, IEEE Xplore, and the ACM Digital Library, were searched in February 2024 to identify related publications. Eligible articles were classification, association, or prediction studies involving human PA monitored through wearable accelerometers. RESULTS After screening 1312 articles, 428 (32.62%) eligible studies were identified and categorized into at least 1 of the following 3 thematic categories: classification (75/428, 17.5%), association (342/428, 79.9%), and prediction (32/428, 7.5%). Most articles (414/428, 96.7%) derived PA variables from 3D acceleration, rather than 1D acceleration. All eligible articles (428/428, 100%) considered PA metrics represented in the time domain, while a small fraction (16/428, 3.7%) also considered PA metrics in the frequency domain. The number of studies evaluating the influence of PA on health conditions has increased greatly. Among the studies in our review, regression-type models were the most prevalent (373/428, 87.1%). The machine learning approach for classification research is also gaining popularity (32/75, 43%). In addition to summary statistics of PA, several recent studies used tools to incorporate PA trajectories and account for temporal patterns, including longitudinal data analysis with repeated PA measurements and functional data analysis with PA as a continuum for time-varying association (68/428, 15.9%). CONCLUSIONS Summary metrics can quickly provide descriptions of the strength, frequency, and duration of individuals' overall PA. When the distribution and profile of PA need to be evaluated or detected, considering PA metrics as longitudinal or functional data can provide detailed information and improve the understanding of the role PA plays in health. Depending on the research goal, appropriate analytical tools can ensure the reliability of the scientific findings.

Mc Ardle R, Taylor L, Cavadino A, Rochester L, Del Din S, Kerse N. Characterizing Walking Behaviors in Aged Residential Care Using Accelerometry, With Comparison Across Care Levels, Cognitive Status, and Physical Function: Cross-Sectional Study. JMIR Aging 2024; 7:e53020. [PMID: 38842168 PMCID: PMC11185191 DOI: 10.2196/53020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 03/05/2024] [Accepted: 03/06/2024] [Indexed: 06/07/2024] Open
Abstract
Background Walking is important for maintaining physical and mental well-being in aged residential care (ARC). Walking behaviors are not well characterized in ARC due to inconsistencies in assessment methods and metrics as well as limited research regarding the impact of care environment, cognition, or physical function on these behaviors. It is recommended that walking behaviors in ARC are assessed using validated digital methods that can capture low volumes of walking activity. Objective This study aims to characterize and compare accelerometry-derived walking behaviors in ARC residents across different care levels, cognitive abilities, and physical capacities. Methods A total of 306 ARC residents were recruited from the Staying UpRight randomized controlled trial from 3 care levels: rest home (n=164), hospital (n=117), and dementia care (n=25). Participants' cognitive status was classified as mild (n=87), moderate (n=128), or severe impairment (n=61); physical function was classified as high-moderate (n=74) and low-very low (n=222) using the Montreal Cognitive Assessment and the Short Physical Performance Battery cutoff scores, respectively. To assess walking, participants wore an accelerometer (Axivity AX3; dimensions: 23×32.5×7.6 mm; weight: 11 g; sampling rate: 100 Hz; range: ±8 g; and memory: 512 MB) on their lower back for 7 days. Outcomes included volume (ie, daily time spent walking, steps, and bouts), pattern (ie, mean walking bout duration and alpha), and variability (of bout length) of walking. Analysis of covariance was used to assess differences in walking behaviors between groups categorized by level of care, cognition, or physical function while controlling for age and sex. Tukey honest significant difference tests for multiple comparisons were used to determine where significant differences occurred. The effect sizes of group differences were calculated using Hedges g (0.2-0.4: small, 0.5-0.7: medium, and 0.8: large). Results Dementia care residents showed greater volumes of walking (P<.001; Hedges g=1.0-2.0), with longer (P<.001; Hedges g=0.7-0.8), more variable (P=.008 vs hospital; P<.001 vs rest home; Hedges g=0.6-0.9) bouts compared to other care levels with a lower alpha score (vs hospital: P<.001; Hedges g=0.9, vs rest home: P=.004; Hedges g=0.8). Residents with severe cognitive impairment took longer (P<.001; Hedges g=0.5-0.6), more variable (P<.001; Hedges g=0.4-0.6) bouts, compared to those with mild and moderate cognitive impairment. Residents with low-very low physical function had lower walking volumes (total walk time and bouts per day: P<.001; steps per day: P=.005; Hedges g=0.4-0.5) and higher variability (P=.04; Hedges g=0.2) compared to those with high-moderate capacity. Conclusions ARC residents across different levels of care, cognition, and physical function demonstrate different walking behaviors. However, ARC residents often present with varying levels of both cognitive and physical abilities, reflecting their complex multimorbid nature, which should be considered in further work. This work has demonstrated the importance of considering a nuanced framework of digital outcomes relating to volume, pattern, and variability of walking behaviors among ARC residents.

Lin YT, Song CY. Reliability and minimal detectable change of the Short Physical Performance Battery in older adults with mild cognitive impairment. Geriatr Nurs 2024; 57:91-95. [PMID: 38603952 DOI: 10.1016/j.gerinurse.2024.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 03/07/2024] [Accepted: 04/03/2024] [Indexed: 04/13/2024]
Abstract
OBJECTIVES Reliability of the Short Physical Performance Battery (SPPB) are rarely examined among older adults with mild cognitive impairment (MCI). This study aimed to investigate the test-retest reliability and minimal detectable change (MDC) of the SPPB in older adults with MCI. METHODS Participants included 100 older adults with MCI. The SPPB was assessed with the first 2 assessments separated by a 20-min interval and the third separated by a 1-week interval. The intraclass correlation coefficient (ICC) and MDC values were estimated. RESULTS The intraday ICC was 0.73 for the SPPB score, 0.90 for the 4-m walk time (4mwt), and 0.95 for the 5-times chair stand time (5cst); the corresponding interday ICC values were 0.76, 0.89, and 0.91, respectively. The MDC values ranged from 1.1 to 1.2 for the SPPB score, from 0.77 to 0.80 s for the 4mwt, and from 1.32 to 1.77 for the 5cst. CONCLUSIONS The SPPB had satisfactory reliability among older adults with MCI. The test-retest reliability of the SPPB is sufficient (>0.7) for group comparisons. Moreover, the test-retest reliability for the 4mwt and 5cst subscale performances is acceptable (> 0.9) for individual-level measurements over time.

Abstract
BACKGROUND Maintaining physical performance in older age is critical. The Short Physical Performance Battery (SPPB) is one of many tools available to measure physical performance in older people. PURPOSE Describe the psychometric properties of the SPPB. METHODS Using a systematic review methodology, quantitative studies addressing the validity, reliability, and sensitivity of the SPPB in populations 60 years or older were included. We searched 8 databases: MEDLINE, CINAHL, Cochrane, Ageline, Amed, Embase, Scopus, and Emcare, as well as gray literature. Two researchers independently screened, appraised, and extracted data from the literature, following which a descriptive synthesis was undertaken. RESULTS Twenty-eight studies with varying methodological quality were included. Floor and ceiling effects were reported in 4 studies, generally related to very high or very low functioning adults. Nineteen studies investigated validity with varying correlations between the SPPB and other physical performance assessment tools. Ten studies reported good to excellent reliability (intraclass correlation coefficient ranging 0.82-0.92). Minimum detectable change indicates low sensitivity (ranging 0.7-3.42). DISCUSSION Evidence from the literature indicates that the SPPB is a reliable and valid measure of physical performance in adults older than 60 years. However, the SPPB has a narrow scope and is most appropriate for frail older adults who can ambulate and are cognitively able to follow instructions. It has limited applicability for specific populations such as people with dementia who have difficulty following instructions. Targeted training for users may improve its usability and success in clinical practice. CONCLUSIONS Clinicians should be mindful that while the SPPB has good validity and reliability, it has limited applicability for people with dementia and is not particularly sensitive to change. In practice, this means that it provides a good snapshot of a client's physical performance compared with the rest of the older population; it is less useful for tracking changes to physical performance over time.

Front Public Health 2023; 11:1241668. [PMID: 37645705 PMCID: PMC10461811 DOI: 10.3389/fpubh.2023.1241668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Accepted: 07/24/2023] [Indexed: 08/31/2023] Open
Abstract
Background This study aimed to explore the association between physical activity (PA) and fear of falling (FOF) and to determine whether this relationship was mediated by physical fitness (PF) in community-dwelling older women. Methods For this cross-sectional study, a total of 1,108 older women were recruited. Moderate-to-vigorous physical activity (MVPA) and light physical activity (LPA) were objectively measured by accelerometers. Physical fitness indicators including body mass index (BMI), forced vital capacity, choice reaction time, grip strength, sit and reach, and five times sit-to-stand were measured. FOF was evaluated by the Chinese version of the activities-specific balance confidence scale. A stepwise linear regression model analysis was used for mediation analysis, and bootstrap analysis was used to verify the mediation effects. Result The Pearson correlation coefficient results suggested that MVPA was significantly and negatively correlated with FOF while LPA was not correlated with FOF. Logistic regression analysis suggested a significant association between MVPA, BMI, forced vital capacity, choice reaction time, sit and reach, grip strength, five times sit-to-stand, and FOF. The mediation analysis showed a negative relationship between MVPA and FOF. BMI completely mediated the relationship between MVPA and FOF while sit and reach, five times sit-to-stand, and forced vital capacity partially mediated the relationship between MVPA and FOF. Conclusion Accumulation of more daily MVPA was associated with reducing the odds of FOF in community-dwelling older women. PF indicators fully or partially mediate the relationship between MVPA and FOF. Therefore, more intervention efforts should focus on the promotion of MVPA to improve PF and thus reduce FOF among older women.

Association between Depression Severity and Physical Function among Chinese Nursing Home Residents: The Mediating Role of Different Types of Leisure Activities. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19063543. [PMID: 35329225 PMCID: PMC8955444 DOI: 10.3390/ijerph19063543] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 03/10/2022] [Accepted: 03/14/2022] [Indexed: 12/04/2022]
Abstract
Despite strong evidence associating depression with poor physical function, the underlying mechanisms of this association remain unknown. This study aimed to ascertain whether different types of leisure activities mediate the effect of depression severity on physical function. This cross-sectional descriptive study included 353 Chinese nursing home residents (aged ≥ 60 years; 197 female) from nursing homes of five districts (Lixia, Tianqiao, Huaiyin, Shizhong, and Licheng) in Jinan, Shandong Province, China, from March to June 2018. Multiple-mediation analyses, including regression and bootstrap analyses, were conducted to evaluate the association of depressive symptoms’ severity and active or passive leisure activities with physical function. Active, but not passive, leisure activities significantly mediated the effect of moderate/severe depressive symptoms on physical function compared to those without depressive symptoms. In contrast, there was no significant association between mild depressive symptoms and physical function. This study demonstrates that leisure activities affect the association between depressive symptoms’ severity and physical function, and its protective role depends on the type of leisure activities. Interventions for physical function should be designed by focusing on active leisure activities among older adults, especially those with moderate/severe depressive symptoms, to delay physical function and improve overall well-being.

Abstract
BACKGROUND Care home (CH) residents are mainly inactive, leading to increased dependency and low mood. Strategies to improve activity are required. DESIGN AND SETTING Cluster randomised controlled feasibility trial with embedded process and health economic evaluations. Twelve residential CHs in Yorkshire, United Kingdom, were randomised to the MoveMore intervention plus usual care (UC) (n = 5) or UC only (n = 7). PARTICIPANTS Permanent residents aged ≥65 years. INTERVENTION MoveMore: a whole home intervention involving all CH staff designed to encourage and support increase in movement of residents. OBJECTIVES AND MEASUREMENTS Feasibility objectives relating to recruitment, intervention delivery, data collection and follow-up and safety concerns informed the feasibility of progression to a definitive trial. Data collection at baseline, 3, 6 and 9 months included: participants' physical function and mobility, perceived health, mood, quality of life, cognitive impairment questionnaires; accelerometry; safety data; intervention implementation. RESULTS 300 residents were screened; 153 were registered (62 MoveMore; 91 UC). Average cluster size: MoveMore: 12.4 CHs; UC: 13.0 CHs. There were no CH/resident withdrawals. Forty (26.1%) participants were unavailable for follow-up: 28 died (12 MoveMore; 16 UC); 12 moved from the CH. Staff informant/proxy data collection for participants was >80%; data collection from participants was <75%; at 9 months, 65.6% of residents provided valid accelerometer data; two CHs fully, two partially and one failed to implement the intervention. There were no safety concerns. CONCLUSIONS Recruiting CHs and residents was feasible. Intervention implementation and data collection methods need refinement before a definitive trial. There were no safety concerns.

Abstract
OBJECTIVES The purpose of this study was to evaluate the Function-Focused Care for Assisted Living Using the Evidence Integration Triangle (FFC-AL-EIT) intervention. DESIGN FFC-AL-EIT was a randomized controlled pragmatic trial including 85 sites and 794 residents. INTERVENTION FFC-AL-EIT was implemented by a Research Nurse Facilitator working with a facility champion and stakeholder team for 12 months to increase function and physical activity among residents. FFC-AL-EIT included (Step I) Environment and Policy Assessments; (Step II) Education; (Step III) Establishing Resident Function-Focused Care Service Plans; and (Step IV) Mentoring and Motivating. SETTING AND PARTICIPANTS The age of participants was 89.48 years [standard deviation (SD) = 7.43], and the majority were female (n = 561; 71%) and white (n = 771; 97%). METHODS Resident measures, obtained at baseline, 4, and 12 months, included function, physical activity, and performance of function-focused care. Setting outcomes, obtained at baseline and 12 months, included environment and policy assessments and service plans. RESULTS Reach was based on 85 of 90 sites that volunteered (94%) participating. Effectiveness was based on less decline in function (P < .001), more function-focused care (P = .012) and better environment (P = .032) and policy (P = .003) support for function-focused care in treatment sites. Adoption was supported with 10.00 (SD = 2.00) monthly meetings held, 77% of settings engaged in study activities as or more than expected, and direct care workers providing function-focused care (63% to 68% at 4 months and 90% at 12 months). The intervention was implemented as intended, and education was received based on a mean knowledge test score of 88% correct. Evidence of maintenance from 12 to 18 months was noted in treatment site environments (P = .35) and policies continuing to support function-focused care (P = .28)]. CONCLUSIONS AND IMPLICATIONS The Evidence Integration Triangle is an effective implementation approach for assisted living. Future work should continue to consider innovative approaches for measuring RE-AIM outcomes.

Abstract
Background
Care home residents are mainly inactive, leading to increased dependency and low mood. Although exercise classes may increase activity, a more sustainable model is to engage staff and residents in increasing routine activity.
Objectives
The objectives were to develop and preliminarily test strategies to enhance the routine physical activity of care home residents to improve their physical, psychological and social well-being through five overlapping workstreams.
Design
This trial had a mixed-methods research design to develop and test the feasibility of undertaking an evaluative study consisting of gaining an understanding of the opportunities for and barriers to enhancing physical activity in care homes (workstream 1); testing physical activity assessment instruments (workstream 2); developing an intervention through a process of intervention mapping (workstream 3); refining the provisional intervention in the care home setting and clarifying outcome measurement (workstream 4); and undertaking a cluster randomised feasibility trial of the intervention [introduced via three facilitated workshops at baseline (with physiotherapist input), 2 weeks (with artist input) and 2 months], with embedded process and health economic evaluations (workstream 5).
Setting
The trial was set in 12 residential care homes differing in size, location, ownership and provision in Yorkshire, UK.
Participants
The participants were elderly residents, carers, managers and staff of care homes.
Intervention
The intervention was MoveMore, designed for the whole home, to encourage and support the movement of residents in their daily routines.
Main outcome measures
The main outcome measures related to the feasibility and acceptability of implementing a full-scale trial in terms of recruitment and retention of care homes and residents, intervention delivery, completion and reporting of baseline data and outcomes (including hours of accelerometer wear, hours of sedentary behaviour and hours and type of physical activity), and safety and cost data (workstream 5).
Results
Workstream 1 – through a detailed understanding of life in a care home, a needs assessment was produced, and barriers to and facilitators of activity were identified. Key factors included ethos of care; organisation, management and delivery of care; use of space; and the residents’ daily routines. Workstream 2 – 22 (73.3%) out of 30 residents who wore a hip accelerometer had valid data (≥ 8 hours on ≥ 4 days of the week). Workstream 3 – practical mechanisms for increasing physical activity were developed, informed by an advisory group of stakeholders and outputs from workstreams 1 and 2, framed by the process of intervention mapping. Workstream 4 – action groups were convened in four care homes to refine the intervention, leading to further development of implementation strategies. The intervention, MoveMore, is a whole-home intervention involving engagement with a stakeholder group to implement a cyclical process of change to encourage and support the movement of residents in their daily routines. Workstream 5 – 12 care homes and 153 residents were recruited to the cluster randomised feasibility trial. Recruitment in the care homes varied (40–89%). Five care homes were randomised to the intervention and seven were randomised to usual care. Predetermined progression criteria were recruitment of care homes and residents (green); intervention delivery (amber); and data collection and follow-up – 52% of residents provided usable accelerometer data at 9 months (red), > 75% of residents had reported outcomes at 9 months (green, but self-reported resident outcomes were red), 26% loss of residents to follow-up at 9 months [just missing green criterion (no greater than 25%)] and safety concerns (green).
Limitations
Observations of residents’ movements were not conducted in private spaces. Working with care home residents to identify appropriate outcome measures was challenging. Take-up of the intervention was suboptimal in some sites. It was not possible to make a reliably informed decision on the most appropriate physical activity end point(s) for future use in a definitive trial.
Conclusions
A whole-home intervention was developed that was owned and delivered by staff and was informed by residents and staff. The feasibility of conducting a cluster randomised controlled trial was successfully tested: the target numbers of care homes and residents were recruited, demonstrating that it is possible to recruit care home residents to a cluster randomised trial, although this process was time-consuming and resource heavy. A large data set was collected, which provided a comprehensive picture of the environment, residents and staff in care homes. Extensive quantitative and qualitative work comprehensively explored a neglected area of health and social care research. Completion of ethnographic work in a range of settings enabled the production of an in-depth picture of life in care homes that will be helpful for other researchers considering organisational change in this setting.
Future work
The content and delivery of the intervention requires optimisation and the outcome measurement requires further refinement prior to undertaking a full trial evaluation. Consideration could be given to a recommended, simplified, core outcome set, which would facilitate data collection in this population.

Quantifying physical activity in aged residential care facilities: A structured review. Ageing Res Rev 2021; 67:101298. [PMID: 33592308 DOI: 10.1016/j.arr.2021.101298] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 01/29/2021] [Accepted: 02/09/2021] [Indexed: 01/27/2023]
Abstract
BACKGROUND Engaging aged residential care (ARC) residents with physical activity (PA) may be a useful strategy to decelerate dependence and disability. It is unclear what volume, intensity and patterns of PA ARC residents participate in. This review aims to synthesize the literature to quantify the volume, intensity and pattern of PA that ARC residents participate in across differing care levels (e.g. low, intermediate, high, mixed), and make recommendations for future research. METHODS 30 studies of 48,760 yielded were reviewed using systematic review strategies. RESULTS Questionnaires and technological tools were used to assess PA, with accelerometers employed in 70% of studies. Overall, studies reported low volumes and intensities of PA across all care levels, and suggested limited variation in patterns of PA (e.g. little day-to-day variation in total PA). There was limited inclusion of people with cognitive impairment, potentially causing representativeness bias. Findings were limited by lack of consistency in methodological approaches and PA outcomes. DISCUSSION Based on findings and limitations of current research, we recommend that total volume or low-light intensity PA are more useful interventional outcomes than higher-intensity PA. Researchers also need to consider which methodology and PA outcomes are most useful to quantify PA in ARC residents.

Impact of current or past physical activity level on functional capacities and body composition among elderly people: a cross-sectional analysis from the YMCA study. ACTA ACUST UNITED AC 2021; 79:50. [PMID: 33858506 PMCID: PMC8048256 DOI: 10.1186/s13690-021-00573-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Accepted: 04/03/2021] [Indexed: 12/25/2022]
Abstract
Background Physical activity (PA) is recognized as important predictor of healthy aging. However, the influence of the type of voluntary PA as well as age or sex in this relationship is unclear. Thus, we assess the association between current and past PA level and physical performances among voluntary active older adults. Methods Functional capacities (timed Up and Go, sit-to-stand, alternate step test, unipodal balance, grip strength, knee extension strength, estimated muscle power and VO2 max) as well as body composition (DXA: total and appendicular lean masses (LM; kg), fat mass (FM; %)) were measured. Current and last 5-years PA level (time spent on total, aerobic, resistance and body & mind activities) were assessed using an interview. Multiple regressions, adjusted on age, sex and BMI, were performed to assess the relationship between current or past PA level and physical performances. Sub-group analysis, according to the sex (men/women) or age (< 65 yrs. vs. ≥65 yrs) were performed. Results 525 subjects (age:61.7 ± 8.1 yrs.; women:68.9%; BMI:26.4 ± 4.8 kg/m2) were enrolled in this study. After adjustment on confounding factors, total current PA level has positive impact on total FM (β = − 2.09, p = 0004) and balance (β = 0.10; p = 0.05). Moreover, current body & mind activities influence total LBM (β = − 0.22, p = 0.02) and balance (β = 0.17; p = 0.001) whereas resistance activities influence total LBM (β = 0.17; p = 0.05), FM (β = − 0.16; p = 0.04) and sit-to-stand capacities (β = − 0.10; p = 0.05). Globally, these results were more pronounced in women than in men and among people aged over 65 years. Past level of PA has low impact on functional capacities and body composition, regardless of sex. Among people < 65 years, there is no relationship between time spent on total PA and functional capacities or body composition. However, a significant correlation was found between past total PA and balance (r=` 0.19; p = 0.01), alternate-step test (r = 0.24; p = 0.02) and VO2max (r = 0.19; p = 0.02) in people aged over 65 years. More precisely, the past time spent on aerobic and resistance activities influence balance (r = 0.16; p = 0.03 and r = 0.15; p = 0.04, respectively) after 65 yrs. old. Conclusion Even if physical activity history has little influence on physical aging process, being active is associated with body composition and functional capacities, especially among women aged 65 years and over.

Lack of Correlation between Accelerometers and Heart-Rate Monitorization during Exercise Session in Older Adults. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17155518. [PMID: 32751725 PMCID: PMC7432703 DOI: 10.3390/ijerph17155518] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 07/21/2020] [Accepted: 07/24/2020] [Indexed: 11/18/2022]
Abstract
Aging is increasing worldwide; hence, aging-related health is also more relevant. Well-programmed physical exercise is now an indispensable tool to achieve active aging and preserve older people’s health. Such “well-programmed” exercise requires efficient and useful tools to measure the activity. The objective of this study is to evaluate the effectiveness of accelerometers to estimate two different intensities of physical exercise in older people. Thirty-eight subjects (64.5 ± 5.3 years) were measured during two different sessions of physical exercise: one moderate in intensity, the other of low intensity. Heart rate and accelerometry were recorded and analyzed. The results showed that the two variables in the physical exercise sessions were not highly correlated, and that accelerometry did not seem useful to assess low-intensity sessions not based on walking.

Abstract
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.

Abstract
PURPOSE To investigate the validity and test-retest reliability of a single seven-level scale physical activity assessment question (SR-PA L7) and its three-level categorization (SR-PA C3). METHODS The associations of SR-PA L7 and C3 with accelerometer-measured leisure-time physical activity (ACC-LTPA) and with the results of four different physical performance tests (6-min walk [n = 733], knee extension [n = 695], vertical jump [n = 731], and grip force [n = 780]) were investigated among women aged 47-55 years participating in the Estrogenic Regulation of Muscle Apoptosis study (n = 795). The reliability was studied using Spearman correlations with 4-month test-retest period (n = 152). RESULTS SR-PA L7 and C3 had low correlations with ACC-LTPA (rs = .105-.337). SR-PA L7, SR-PA C3, and ACC-LTPA explained comparable but small amount of variance of the physical performance test results. The reliability analysis provided moderate agreement (rs = .707 and .622 for SR-PA L7 and C3, respectively). CONCLUSIONS SR-PA L7 and C3 demonstrated limited validity and reasonable repeatability.

Modifiable Physical Factors Associated With Physical Functioning for Patients Receiving Dialysis: A Systematic Review. J Phys Act Health 2020; 17:475-489. [DOI: 10.1123/jpah.2019-0338] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2019] [Revised: 11/10/2019] [Accepted: 12/29/2019] [Indexed: 11/18/2022]
Abstract
Background: Patients receiving dialysis have reduced physical function, which is associated with unfavorable clinical outcomes and decreased quality of life. The authors aimed to identify and explore modifiable physical factors associated with physical function for patients receiving dialysis. Methods: Searches were performed in MEDLINE, Embase, Ovid Emcare, and The Cochrane Library in October 2018. Etiological studies involving dialysis populations that report association or predictive statistics between a modifiable physical factor and physical function were eligible for inclusion. Predictor variables were (1) modifiable via exercise and (2) considered an impairment in the International Classification of Functioning, Disability and Health. Results: Of 5384 titles screened, 23 studies were included. Thirteen studies focused on physical activity levels and muscle strength and the relationship with physical function while 2 studies investigated sedentary behavior. Twenty-one studies focused on hemodialysis populations. Studies related to physical activity levels displayed a moderately strong relationship with physical function, whereas muscle strength displayed a predominantly weak to moderate relationship. Conclusions: Physical activity levels, sedentary behavior levels, and muscle strength are related to physical function status for patients receiving dialysis. There is a need for robust longitudinal data to confirm the results of this investigation and for more focus on populations receiving peritoneal dialysis.

Abstract
The purpose of the current study was to test for gender differences among residents living in assisted living settings. This was a secondary data analysis using data from the first 64 facilities participating in the ongoing Function Focused Care for Assisted Living study using the Evidence Integration Triangle (FFC-AL-EIT). A total of 593 residents were recruited. Differences by gender with regard to function, physical activity, falls, total number of medications, and satisfaction with assisted living were tested using multivariate analysis of variance. There were 166 (28%) men and 427 (72%) women with a mean age of 88 (SD = 7.5 years). Participants had five (SD = 2) comorbidities and took on average 6.88 medications (SD = 3.47). Participants had moderate functional impairment with a mean of 64.13 (SD = 19.09) on the Barthel Index and engaged in 43.8 (SD = 76.12) minutes daily of moderate level physical activity. Women reported higher satisfaction with activities (4.32 [SD = 1.14]) than men (3.85 [SD = 1.51]), and women received more medications than men (7.09 [SD = 3.51] vs. 6.34 [SD = 3.31]). Current study findings suggest that deprescribing may be particularly important for women versus men and focusing on expanding activity options to include those preferred by men should be considered in assisted living settings.

Abstract
PURPOSE There is a growing number of older adults moving into assisted-living facilities to maintain their independence while being assisted with certain tasks and having convenient access to services. Physical activity (PA) and vitality play an important role in independence, as well as in mental health, of older adults. However, no research has examined the difference in older adults' levels of vitality (defined as the state of feeling alive and alert) between those living in assisted-living facilities and those from community-living settings. This study also explored sociodemographic predictors of PA and vitality among older adults living in two different types of housing. METHODS This cross-sectional study examined differences in PA levels and vitality between older adults (aged ≥ 60 years; n = 148, mean age = 74.70 years) living in assisted-living facilities (n = 85, mean age = 77.46 years) and those in community-living settings (n = 63, mean age = 70.98 years). PA was assessed by accelerometry, and vitality was measured using the subjective vitality scale. RESULTS Engagement in light PA and moderate to vigorous PA was higher in individuals living in community-living settings after controlling for sociodemographic variables. However, vitality was not significantly different between the two types of housing after controlling for sociodemographic variables. Marital status, education, and number of diagnosed diseases were associated with vitality. CONCLUSION The support is needed for designing strategies to increase PA in older adults living in assisted-living facilities. More attention should be paid to increasing subjective vitality of older adults in both types of housing to promote healthy aging.

The Sedentary Time and Physical Activity Levels on Physical Fitness in the Elderly: A Comparative Cross Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16193697.

Abstract
Background: Ageing is a life-long process characterized by a progressive loss of physical fitness compromising strength, flexibility, and agility. The purpose of this study was to use accelerometry to examine the relationship between sedentary time, light physical activity (LPA), and moderate to vigorous physical activity (MVPA) with the elderly’s physical fitness. Additionally, we aimed to examine the association between the aforementioned variables on older adults who fulfilled global recommendations on physical activity for health and on those who did not fulfil these recommendations. Methods: Eighty-three elderly (mean ± SD: 72.14 ± 5.61 years old) of both genders volunteered to participate in this cross-sectional study, being divided into an active group (n = 53; 71.02 ± 5.27 years old) and an inactive group (n = 30; 74.13 ± 5.72 years old) according to the established guidelines. Sedentary and physical activity times were assessed using an ActiGraph® GT1M accelerometer, whereas physical fitness was evaluated with the Senior Fitness Test. Results: MVPA time was correlated with lower body mass index (BMI) ((rs = −0.218; p = 0.048; −0.3 < r ≤ −0.1 (small)) and shorter time to complete the agility test ((rs = −0.367; p = 0.001; −0.5 < r ≤ −0.3 (low)). Moreover, MVPA time was positively correlated with aerobic endurance ((rs = 0.397; p = 0.000; 0.5 < r ≤ 0.3 (low)) and strength ((rs = 0.243; p = 0.027; 0.3 < r ≤ 0.1 (small)). In the inactive group, MVPA time was positively correlated with upper limb flexibility ((rs = 0.400; p = 0.028; 0.5 < r ≤ 0.3 (low)); moreover, sedentary time was negatively correlated with upper limb flexibility ((r = −0.443; p = 0.014; −0.5 < r ≤ −0.3 (low)), and LPA time was negatively correlated with BMI ((r = −0.423; p = 0.020; −0.5 < r ≤ −0.3 (low)). In the active group, MVPA time was correlated with lower BMI ((rs = −0.320; p = 0.020; −0.5 < r ≤ −0.3 (low)), and shorter time to complete agility test ((rs = −0.296; p = 0.031; −0.3 < r ≤ −0.1 (small)). Conclusions: Our results reinforce the importance of promoting MVPA practice among the elderly, thereby allowing physical fitness maintenance or improvement.

Abstract
Mobility restriction as a consequence of a fall is a major issue in assisted-living facilities. Although many factors are related to falling, little is known about the relationship between falls, social support, falls efficacy, and physical activity. The authors examined the relationship between falls and the Social Support Questionnaire, the Activities-specific Balance Confidence scale, and physical activity simultaneously in 81 older adults (66-94 years) using structural equation modeling. The structural equation model revealed that being older was associated with lower falls efficacy and a higher number of falls, and higher falls efficacy was associated with a higher number of steps per day. The development of a structural equation model illustrating the mediating effects of social support and falls efficacy on the relationship between falls and physical activity can help health care professionals in predicting risk factors of falls that may be compromised by residing in an assisted-living facility.

Abstract
Objective: Given that one in four older adults suffer potentially preventable falls annually, we aimed to identify areas with (a) delivery gaps of evidence-based programs (EBPs) targeting fall prevention among older adults, namely A Matter of Balance (AMOB), and (b) high rates of fall-related hospitalizations—hotspots. Method: Analyses included multiple geospatially linked datasets. Results: EBPs were delivered ≥1 time in 84 counties in 2012 and 90 counties in 2014. Factors associated with EPB delivery gaps (absence; p<.05) included high-density older adult areas, non-fall-related hospitalization hotspots, lower population density, nonmetropolitan areas, high-density Hispanic adult areas, and areas with limited access to home health care agencies. Hotspots for fall-related hospitalization numbered 64 in 2012 and 62 in 2014. Factors associated with hotspots included low-density older adult areas, having AMOB delivered ≥1 time annually, high population density, and high-density Hispanic adult areas. Discussion: In resource-finite settings (e.g., the aging services sector), identifying high priority areas allows for precise allocation of limited resources.

Associations Between Objectively Measured Physical Activity, Body Composition and Sarcopenia: Findings from the Hertfordshire Sarcopenia Study (HSS). Calcif Tissue Int 2018; 103:237-245. [PMID: 29589060 PMCID: PMC6049619 DOI: 10.1007/s00223-018-0413-5] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2018] [Accepted: 03/16/2018] [Indexed: 01/06/2023]
Abstract
Regular physical activity (PA) is associated with reduced risk of the development and progression of musculoskeletal, metabolic and vascular disease. However, PA declines with age and this can contribute to multiple adverse outcomes. The aims of this study were to describe the relationship between accelerometer-determined PA, body composition and sarcopenia (the loss of muscle mass and function with age). Seven-day PA was measured using the GENEactiv accelerometer among 32 men and 99 women aged 74-84 years who participated in the Hertfordshire Sarcopenia Study. We measured mean daily acceleration and minutes/day spent in non-sedentary and moderate-to-vigorous physical activity (MVPA) levels. Body composition was measured by dual-energy X-ray absorptiometry, muscle strength by grip dynamometry and function by gait speed. Sarcopenia was defined according to the EWGSOP diagnostic algorithm. Men and women spent a median (inter-quartile range) of 138.8 (82, 217) and 186 (122, 240) minutes/day engaging in non-sedentary activity but only 14.3 (1.8, 30.2) and 9.5 (2.1, 18.6) min in MVPA, respectively. Higher levels of PA were associated with reduced adiposity, faster walking speed and decreased risk of sarcopenia. For example, a standard deviation (SD) increase in mean daily acceleration was associated with an increase in walking speed of 0.25 (95% CI 0.05, 0.45) SDs and a reduction in the risk of sarcopenia of 35% (95% CI 1, 57%) in fully adjusted analyses. PA was not associated with hand grip strength. Community-dwelling older adults in this study were largely sedentary but there was evidence that higher levels of activity were associated with reduced adiposity and improved function. PA at all intensity levels in later life may help maintain physical function and protect against sarcopenia.

Physical activity and associated medical cost savings among at-risk older adults participating a community-based health & wellness program. PLoS One 2018; 13:e0198239. [PMID: 29894478 PMCID: PMC5997342 DOI: 10.1371/journal.pone.0198239] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Accepted: 05/16/2018] [Indexed: 12/04/2022] Open
Abstract
Introduction Physical activity declines are seen with increasing age; however, the US CDC recommends most older adults (age 65 and older) engage in the same levels of physical activity as those 18–64 to lessen risks of injuries (e.g., falls) and slow deteriorating health. We aimed to identify whether older adults participating in a short (approx. 90-minute sessions) 20 session (approximately 10-weeks) health and wellness program delivered in a community setting saw improvements in physical activity and whether these were sustained over time. Methods Employing a non-equivalent group design, community-dwelling older adults were purposely recruited into either an intervention or comparison group. The intervention was a multicomponent lifestyle enhancement intervention focused on healthy eating and physical activity, including structured physical activity exercises within the class sessions. Two groups were included: intervention (survey group: n = 65; accelerometer subgroup: n = 38) and the comparison group (survey group: n = 102; accelerometer subgroup: n = 55). Measurements were made at baseline and approximately three months later to reflect immediate post-treatment period (survey, accelerometer) with long-term follow-up 6 months after baseline (survey). Adults not meeting the physical activity guidelines (i.e., 150/75 minutes of moderate-to-vigorous physical activity or MVPA) were targeted for subgroup analyses. Paired t-tests were used for bivariate comparisons, while repeated measures random coefficient models (adjusting for propensity scores using inverse probability of treatment weighted (IPTW) estimation) were used for multivariate models. Estimated medical costs associated with gains in physical activity were also measured among survey respondents in the intervention group. Results The accelerometer group contained 38 participants in the intervention group with 71% insufficiently active at baseline and 55 participants in the comparison group with 76% insufficiently active at baseline (<150 weekly MVPA minutes). The survey group contained 65 participants in the intervention group with 73.85% insufficiently active at baseline and 102 participants in the comparison group with 76.47% insufficiently active at baseline. In paired t-tests with the accelerometer group, a moderate effect size (-0.4727, p = 0.0210) indicating higher MVPA was found for intervention participants with <150 weekly MVPA at baseline. In fully adjusted analyses using propensity score matching, among the subjectively measured physical activity (survey) group, there was a differential impact from baseline to 6-month post among the intervention group with an improvement of 160 minutes among all study participants (p < .0001) versus no difference among the comparison group. For those insufficiently active at baseline, there was an improvement of 103 minutes among intervention (p < .0001) and 55 minutes among the comparison (p < .0001) with the improvement of the intervention significantly greater than that among the comparison (p = 0.0224). Further, among those insufficiently active at baseline there was a relative cost savings from baseline to 6-months over and above the estimated cost of the intervention estimated between $143 and $164 per participant. Discussion This intervention was able to reach and retain older adults and showed significant MVPA gains and estimated medical cost savings among more at-risk individuals (baseline <150 MVPA). This intervention can be used in practice as a strategy to improve MVPA among the growing population of older community-dwelling adults.

The association of locomotive and non-locomotive physical activity measured by an accelerometer with functional fitness in healthy elderly men: a pilot study. J Exerc Nutrition Biochem 2018; 22:41-48.

Abstract
PURPOSE The purpose of this study was to investigate the relationship of various aspects of daily physical activity, such as the number of steps, time spent in moderate to vigorous intensity physical activity (MVPA), and locomotive and non-locomotive MVPA measured by a triaxial accelerometer, with the functional fitness in healthy elderly men. METHODS The subjects of this study were 22 healthy elderly men aged over 65 years. The participants wore a triaxial accelerometer for two weeks to estimate their daily physical activities. The level of functional fitness was measured based on "National Fitness Award 100 in Korea" immediately after the measurement of two weeks of daily physical activities. RESULTS The results showed that active healthy elderly men with more than 6,500 walking steps per day and more than 60 min per day spent in MVPA showed a significantly higher 2-min marching in place and index of cardiorespiratory endurance compared to less physically active participants. Particularly, locomotive MVPA was significantly associated with cardiorespiratory endurance levels (r = 0.50), whereas non-locomotive MVPA was not associated with other measurements of functional fitness. CONCLUSION Increased MVPA time, especially the locomotive MVPA, can effectively suppress the decrease in cardiorespiratory endurance level in elderly men. However, no association was observed between non-locomotive MVPA, such as household activities, and functional fitness in healthy elderly men.

Abstract
Understanding the minimal dose of physical activity required to achieve improvement in physical functioning and reductions in disability risk is necessary to inform public health recommendations. To examine the effect of physical activity dose on changes in physical functioning and the onset of major mobility disability in The Lifestyle Interventions and Independence for Elders (LIFE) Study. We conducted a multicenter single masked randomized controlled trial that enrolled participants in 2010 and 2011 and followed them for an average of 2.6 years. 1,635 sedentary men and women aged 70-89 years who had functional limitations were randomized to a structured moderate intensity walking, resistance, and flexibility physical activity program or a health education program. Physical activity dose was assessed by 7-day accelerometry and self-report at baseline and 24 months. Outcomes included the 400 m walk gait speed, the Short Physical Performance Battery (SPPB), assessed at baseline, 6, 12, and 24 months, and onset of major mobility disability (objectively defined by loss of ability to walk 400 m in 15 min). When the physical activity arm or the entire sample were stratified by change in physical activity from baseline to 24 months, there was a dose-dependent increase in the change in gait speed and SPPB from baseline at 6, 12, and 24 months. In addition, the magnitude of change in physical activity over 24 months was related to the reduction in the onset of major mobility disability (overall P < 0.001) (highest versus the lowest quartile of physical activity change HR 0.23 ((95% CI:0.10-0.52) P = 0.001) in the physical activity arm. We observed a dose-dependent effect of objectively monitored physical activity on physical functioning and onset of major mobility disability. Relatively small increases (> 48 minutes per week) in regular physical activity participation had significant and clinically meaningful effects on these outcomes.

Abstract
OBJECTIVES The interactions between nutritional supplementation and physical activity on changes in physical function among older adults remain unclear. The primary objective of this study was to examine the impact of nutritional supplementation plus structured physical activity on 400M walk capacity in mobility-limited older adults across two sites (Boston, USA and Stockholm, Sweden). DESIGN All subjects participated in a physical activity program (3x/week for 24 weeks), involving walking, strength, balance, and flexibility exercises. Subjects were randomized to a daily nutritional supplement (150kcal, 20g whey protein, 800 IU vitamin D) or placebo (30kcal, non-nutritive). SETTING Participants were recruited from urban communities at 2 field centers in Boston MA USA and Stockholm SWE. PARTICIPANTS Mobility-limited (Short Physical Performance Battery (SPPB) ≤9) and vitamin D insufficient (serum 25(OH) D 9 - 24 ng/ml) older adults were recruited for this study. MEASUREMENTS Primary outcome was gait speed assessed by the 400M walk. RESULTS 149 subjects were randomized into the study (mean age=77.5±5.4; female=46.3%; mean SPPB= 7.9±1.2; mean 25(OH)D=18.7±6.4 ng/ml). Adherence across supplement and placebo groups was similar (86% and 88%, respectively), and was also similar across groups for the physical activity intervention (75% and 72%, respectively). Both groups demonstrated an improvement in gait speed with no significant difference between those who received the nutritional supplement compared to the placebo (0.071 and 0.108 m/s, respectively (p=0.06)). Similar effects in physical function were observed using the SPPB. Serum 25(OH)D increased in supplemented group compared to placebo 7.4 ng/ml versus 1.3 ng/ml respectively. CONCLUSION Results suggest improved gait speed following physical activity program with no further improvement with added nutritional supplementation.
