Physical activity level, fear of falling and quality of life: a comparison between community-dwelling and assisted-living older adults

Muscle characteristics of lower limb in association with physical activity in candidates of total knee arthroplasty with knee osteoarthritis

BACKGROUND & AIMS

This study aimed to clarify the association between physical activity (PA) and physical functions, including both muscle quantity and quality of ankle plantar flexor muscles in patients with knee osteoarthritis (OA).

METHODS

A retrospective cohort study was conducted with ninety-two patients with knee OA. PA, leg muscle cross-sectional area (CSA), knee strength, passive knee angle, and knee pain of the affected side were assessed. PA was assessed by the 2011 Knee Society scoring system. CSA of the quadriceps and ankle plantar flexor muscles on the affected side was measured using a computed tomography image. Based on muscle attenuation assessed with Hounsfield units (HU), the muscle quality of targeted muscle was divided into 4 groups as follows: fat tissue (-190 to -30 HU), very low-density muscle (-29 to -1 HU), low-density muscle (0 to 34 HU), and normal-density muscle (NDM, 35 to 100 HU). The CSA was obtained for each of the 4 groups. Univariate and multivariate linear regression analyses were performed to determine the factors associated with PA.

RESULTS

The regression analysis revealed that higher PA was independently associated with the NDM CSA of ankle plantar flexor (β = 0.51), higher knee extension strength (β = 0.28), and milder knee pain (β = -0.29) after adjustment with age, sex, height, weight, and body mass index.

CONCLUSION

The present study suggested that NDM CSA of ankle plantar flexor in addition to knee function is one of the factors determining the PA in patients with knee OA.

Fingertip light touch contact increases anteroposterior limits of stability in healthy young and older adults

BACKGROUND

The limit of stability (LoS), an index of stance balance ability, is reduced in older adults. Although contacting an earth-fixed external surface through fingertips' light touch improves older adults' stance balance control, its effects on the LoS in this population are unclear.

RESEARCH QUESTION

Does light touch increase the LoS and reduce postural sway in the LoS?

METHODS

This study included 20 young adults (11 women and 9 men, mean age = 20.6 years) and 15 community-dwelling older adults (8 women and 7 men, mean age = 74.5 years). The position and path length of the center of pressure (CoP) during quiet standing (QS) and the anterior and posterior LoS (A-LoS and P-LoS, respectively) were measured using a force platform under two touch conditions (no-touch condition and light-touch condition). In light-touch condition, participants placed the tip of their dominant index finger on a load cell, which had an applied force of <1 N.

RESULTS

In both touch conditions, the older group had a more limited CoP position in the anteroposterior LoS and a longer CoP path length in the QS and LoS than the younger group. In both participant groups, the light-touch condition showed a wider CoP position in the anteroposterior LoS and a shorter CoP path length in the QS and LoS than the no-touch condition.

SIGNIFICANCE

Light touch increases the anteroposterior LoS and decreases postural sway in the LoS. Therefore, contacting an external object by fingertips' light touch may be an effective training protocol to increase the LoS in older adults.

Examination of reliability and validity of the Self-Assessment Burden Scale-Motor for community-dwelling older adults in Japan: a validation study

Background

The aging society in Japan is progressing rapidly compared with that in the United States and European countries. Aging limits activities of daily living (ADL) in older adults, declining their lives and functions at home. Therefore, improving their ADL to effectively support their functioning at home for as long as possible is vital. Consequently, supporters need to have a common understanding, be promptly aware of the decline in ADL, and quickly introduce rehabilitation. The Functional Independence Measure (FIM) and Barthel Index (BI) are the main scales used to quantitatively assess ADL. However, previous studies have reported that FIM requires specialized knowledge for evaluation, and BI does not appropriately capture changes in ADL. The Self-Assessment Burden Scale-Motor (SAB-M) was developed as a scale for family caregivers to appropriately assess changes in ADL in older adults. Previous studies using the SAB-M have confirmed its reliability and validity in hospitalized patients as assessed by their family caregivers. Therefore, this study aimed to investigate the reliability and validity of the SAB-M among community-dwelling older adults as assessed by their family caregivers.

Methods

This study included community-dwelling older adults who received home-visit rehabilitation at the first author's facility between October 2020 and December 2020 in Japan. Following previous studies, the SAB-M was used by family caregivers to assess 20 older adults twice for intra-rater reliability. Furthermore, 168 older adults were evaluated by family caregivers for internal consistency using the SAB-M. For criterion validity, the SAB-M was used for the assessment by family caregivers, and therapists used the FIM-Motor (FIM-M). This study used the weighted kappa, Cronbach's alpha, and Spearman's rank correlation coefficients for the statistical analysis of intra-rater reliability, internal consistency, and criterion validity, respectively.

Results

The weighted kappa coefficient for the total score was 0.98 (p < 0.01) and individual item, it was 0.93 for feeding (p < 0.01), 0.91 for bathing (p < 0.01), 0.98 for dressing (p < 0.01), 0.94 for transfer (p < 0.01), 0.94 for walking/wheelchair (p < 0.01), 0.95 for stairs (p < 0.01), and 0.96 for bladder management (p < 0.01). The Cronbach's alpha was 0.93 for the seven items. The Spearman's rank correlation coefficient between the SAB-M and FIM-M scores was 0.91 (p < 0.01).

Conclusion

The SAB-M has sufficient reliability and validity among community-dwelling older adults. Family caregivers can routinely assess changes in the ADL of community-dwelling older adults using the SAB-M, enabling them to promptly consider introducing rehabilitation when older adults' ADL declines. Therefore, implementing SAB-M helps older adults live and function at home for as long as possible.

The global prevalence of and risk factors for fear of falling among older adults: a systematic review and meta-analysis

BACKGROUND

As a common psychological problem among older adults, fear of falling was found to have a wide range prevalence in different studies. However, the global prevalence of it was unknown and a lack of the large sample confirmed its risk factors.

OBJECTIVES

To report the global prevalence of fear of falling and to explore its risk factors among older adults for further developing precise interventions to systematically manage FOF.

DESIGN

A systematic review and meta-analysis was conducted by PRISMA guidelines.

METHODS

Searches were conducted in PubMed, Web of Science, EMBASE, the Cochrane Library and the manual search in August 20, 2022, updated to September 2, 2023. Observational studies published in English were included and two researchers independently screened and extracted the data. Fixed or random effects mode was used to estimate the pooled prevalence of and risk factors for fear of falling. Heterogeneity resources were analyzed by subgroup and sensitivity analysis. Publication bias was assessed through funnel plots, Egger's test and Begg's test.

RESULTS

A total of the 153 studies with 200,033 participants from 38 countries worldwide were identified. The global prevalence of fear of falling was 49.60%, ranging from 6.96-90.34%. Subgroup analysis found the estimates pooled prevalence of it was higher in developing countries (53.40%) than in developed countries (46.7%), and higher in patients (52.20%) than in community residents (48.40%). In addition, twenty-eight risk factors were found a significant associations with fear of falling, mainly including demographic characteristics, physical function, chronic diseases and mental problems.

CONCLUSION

The global prevalence of FOF was high, especially in developing countries and in patients. Demographic characteristics, Physical function, chronic diseases and mental problems were a significant association with FOF. Policy-makers, health care providers and government officials should comprehensively evaluate these risk factors and formulate precise intervention measures to reduce FOF.

TRIAL REGISTRATION

The study was registered in the International Database of Prospectively Registered Systematic Reviews (PROSPERO): CRD42022358031.

Four-Step Co-Designing of the Reablement Strategies Targeting Sarcopenia (ReStart-S): An Exercise-Based Multicomponent Program for Older Adults Residing in Long-Term Care Settings

Background

The prevalence of sarcopenia is concerningly high in long-term care settings (LTCS); yet, no exercise programs specifically targeting older adults living in residential care are available.

Objective

The goal of the present study was to co-design and validate a program named Reablement Strategies targeting Sarcopenia (ReStart-S) for older long-term care residents.

Design

Cross-sectional study with an exploratory phase.

Settings

LTCS in Udupi, Karnataka, India.

Participants

Sarcopenic older adults diagnosed using Asian Working Group for Sarcopenia 2019 criteria.

Material and Methods

The program was designed using a four-step intervention mapping technique involving systematic progression after completing each step. The steps included 1) identifying the appropriate exercise-based intervention for sarcopenia, 2) determining objectives and expected outcomes, 3) seeking expert views through a Delphi consensus approach, and 4) assessing the feasibility of ReStart-S program among older adults living in LTCS.

Results

A comprehensive literature review appraised existing exercise programs for managing sarcopenia. A workshop held with six older adults and one caretaker, decided on morning exercise sessions, recommended 2-7 days/week. The results of the review and workshop were compiled for the Delphi process that had seven experts from 5 countries, achieving a 71% response rate after four rounds. In the last step, a pilot study on eight LTCS residents, two males and six females with a mean age of 78.3 ± 8.3 years, was conducted and the program was found to be feasible.

Conclusion

The ReStart-S program for managing sarcopenia among older adults residing in LTCS incorporates evidence from the literature and the engagement of older adults, caregivers, and experts, making it a contextually appropriate intervention. Our study also provides researchers and healthcare professionals insight into co-designing an intervention program for vulnerable older adults. Finally, the program evaluation indicates that a full-scale trial testing the efficacy of the ReStart-S program is feasible.

A novel wearable biofeedback system to prevent trip-related falls

Real-time gait monitoring of older adults and gait-impaired individuals while providing real-time biofeedback has the potential to help reduce trip-related falls. A low or unsuccessful Minimum Toe Clearance (MTC) is considered a predictor of tripping risk. Thus, increasing the MTC can be a key component in minimizing the likelihood of tripping. This paper discusses a proof-of-concept wearable system that estimates the MTC in real-time using two Time-of-Flight (ToF) sensors and provides auditory biofeedback to alert users if they have a low MTC during everyday walking activities. Ten healthy female adults were asked to perform two experiments: 1) walk at a predetermined speed to evaluate the proposed real-time MTC detection algorithm, and 2) walk in four conditions: baseline, biofeedback with no distraction, biofeedback with distraction 1 (talking on the phone), and biofeedback with distraction 2 (playing a simple mobile game). The average MTC values were significantly greater during all feedback conditions than the baseline, indicating that the proposed system could successfully warn users to increase their MTC in real-time.

Fear of falling: Scoping review and topic analysis using natural language processing

Fear of falling (FoF) is a major concern among older adults and is associated with negative outcomes, such as decreased quality of life and increased risk of falls. Despite several systematic reviews conducted on various specific domains of FoF and its related interventions, the research area has only been minimally covered by scoping reviews, and a comprehensive scoping review mapping the range and scope of the research area is still lacking. This review aims to provide such a comprehensive investigation of the existing literature and identify main topics, gaps in the literature, and potential opportunities for bridging different strains of research. Using the PRISMA-ScR guidelines, we searched the Cochrane Database of Systematic Reviews, CINAHL, Embase, MEDLINE, PsycInfo, Scopus, and Web of Science databases. Following the screening process, 969 titles and abstracts were chosen for the review. Pre-processing steps included stop word removal, stemming, and term frequency-inverse document frequency vectorization. Using the Non-negative Matrix Factorization algorithm, we identified seven main topics and created a conceptual mapping of FoF research. The analysis also revealed that most studies focused on physical health-related factors, particularly balance and gait, with less attention paid to cognitive, psychological, social, and environmental factors. Moreover, more research could be done on demographic factors beyond gender and age with an interdisciplinary collaboration with social sciences. The review highlights the need for more nuanced and comprehensive understanding of FoF and calls for more research on less studied areas.

Daily Posture Behavior Patterns Derived From Multitime-Scale Topic Models Using Wearable Triaxial Acceleration for Assessment of Concern About Falling

Concern about falling is prevalent in older population. This condition would cause a series of adverse physical and psychological consequences for older adults' health. Traditional assessment of concern about falling is relied on self-reported questionnaires and thus is too subjective. Therefore, we proposed a novel multi-time-scale topic modelling approach to quantitatively evaluate concern about falling by analyzing triaxial acceleration signals collected from a wearable pendent sensor. Different posture segments were firstly recognized to extract their corresponding feature subsets. Then, each selected feature related to concern about falling was clustered into discrete levels as feature letters of artificial words in different time scales. As a result, all older participants' signal recordings were converted to a collection of artificial documents, which can be processed by natural language processing methodologies. The topic modelling technique was used to discover daily posture behavior patterns from these documents as discriminants between older adults with different levels of concern about falling. The results indicated that there were significant differences in distributions of posture topics between groups of older adults with different levels of concern about falling. Additionally, the transitions of posture topics over daytime and nighttime revealed temporal regularities of posture behavior patterns of older adult's active and inactive status, which were substantially different for older adults with different levels of concern about falling. Finally, the level of concern about falling was accurately determined with accuracy of 71.2% based on the distributions of posture topics combined with the mobility performance metrics of walking behaviors and demographic information.

Fear of falling: scoping review and topic analysis protocol

INTRODUCTION

Fear of falling (FoF) is a major challenge for the quality of life among older adults. Despite extensive work in previous scoping and systematic reviews on separate domains of FoF and interventions related to FoF, very little attention has been devoted to a comprehensive scoping review mapping the range and scope of this burgeoning area of study, with only a few exceptions. This scoping review aims to provide an overarching review mapping FoF research by identifying main topics, gaps in the literature and potential opportunities for bridging different strains of research on FoF. Such a comprehensive scoping review will allow the subsequent creation of an interdisciplinary theoretical and empirical framework, which may help push forward policy and practice innovations for people living with FoF.

METHODS AND ANALYSIS

Following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Extension for Scoping Reviews (PRISMA-ScR), seven main databases will be searched from 2000 to the date of the start of the review: Cochrane Database of Systematic Reviews, CINAHL, Embase, MEDLINE, PsycInfo, Scopus and Web of Science. The review will include original research in English, published between 2000 and January 2023. Quality checks will be conducted collegially. Data will be extracted and analysed using PRISMA-ScR charting tools and conventions.

ETHICS AND DISSEMINATION

No ethics approval is required for the review. The results will be submitted to a peer-reviewed journal and presented at academic conferences. The outcomes will be disseminated through social media, opinion pieces and science communication platforms to reach a wider audience.

REGISTRATION

The scoping review was registered with the Open Science Framework (https://osf.io/gyzjq).

Interactive Combinations Between Gait Speed and Physical Function at Acute Phase Can Predict the Physical Activity at 2 Years After Total Knee Arthroplasty Using Classification and Regression Tree Analysis

OBJECTIVE

To clarify the interactive combinations of various clinical factors associated with physical activity (PA) at 2 years after total knee arthroplasty (TKA) using classification and regression tree (CART) analysis.

DESIGN

A retrospective cohort study.

SETTING

A single university hospital.

PARTICIPANTS

286 patients who underwent TKA (N=286).

MAIN OUTCOME MEASURES

PA was assessed preoperatively, 3 weeks, and 2 years after TKA. Physical functions, namely, 10 m walking test (10MWT), timed Up and Go test, 1-leg standing time, isometric knee extension and flexion strength, knee joint stability, knee pain, femora-tibial angle, and the passive knee extension and flexion angle, were measured before surgery as a baseline and 3 weeks after TKA as acute phase. CART analysis was conducted to clarify the interactive combinations that accurately predict the PA at 2 years after TKA.

RESULTS

The results of CART analysis indicated that gait speed (≥1.05 m/s) at the acute phase after TKA was the primal predictor for the postoperative PA at 2 years. The highest postoperative PA at 2 years was determined by gait speed (≥1.05 m/s) and PA (>74.5) at the acute phase. The PA at baseline and at acute phase, as well as the body mass index were also selected as predictors of postoperative PA at 2 years.

CONCLUSION

The present study suggested that acquiring gait speed (≥1.05 m/s) and PA (>74.5) in the postoperative acute phase is the predictive of a high PA at 2 years after TKA.

Association between long COVID, functional activity, and health-related quality of life in older adults

BACKGROUND

Older adults experience persistent symptoms post-COVID-19, termed as Long COVID, affecting their physical and mental health. This study aimed to evaluate the effects of Long COVID, level of physical activity, and functional decline on older adults' health-related quality of life post-COVID-19.

METHODS

This cross-sectional study was conducted on 121 older adults with 60 to 90 years old post-coronavirus infection. The standardized metrics used in the study were Fatigue Severity Scale, Physical Activity Elderly, SF12, Post-COVID-19 functional status scale, and COVID-19 Yorkshire rehabilitation screening scale. The severity of coronavirus infection was evaluated by changes in chest CT scan images and O2 saturation at hospital admission. Data were analyzed using linear regression analyses.

RESULTS

The results of regression analysis revealed six factors to be predictors of physical health at 6 months post-COVID-19 (F = 9.046, P < 0.001; explained variance 63%), which the significant factors were fatigue, level of physical activity, worsened pain, difficulties in activities of daily living and cognitive-communication problems. Among these factors, greater fatigue and worsened pain intensity were the strongest predictors. Mental health was associated with days of hospitalization and cognitive-communication problems (F = 2.866, P < 0.001; explained variance 35%).

CONCLUSIONS

Considering the negative impact of fatigue, pain, low physical activity, and cognitive-communication problems on health-related quality of life, early and accurate evaluation and management are required for recovered older adults post-COVID-19.

Needs assessment in community-dwelling older adults toward digital interventions to promote physical activity: Cross-sectional survey study

Background

Tackling physical inactivity represents a key global public health challenge. Strategies to increase physical activity (PA) are therefore warranted. Despite the rising availability of digital interventions (DIs), which offer tremendous potential for PA promotion, there has been inadequate attention to the special needs of older adults.

Objective

The aim was to investigate community-dwelling older adults' needs, requirements, and preferences toward DIs to promote PA.

Methods

The target population of this cross-sectional study was community-dwelling older adults (≥60 years old) within German-speaking Switzerland. Potential respondents were informed about the study and sent a link to a self-developed and self-administered online survey by our cooperating institutions.

Results

Overall, 922 respondents who completed the online survey were included in the final analysis. The mean age of the sample was 72 years (SD 6.4, range 60-98). The preferred delivery mode of DIs to promote PA was a website (428/922, 46.4%) and 80.3% (740/922) preferred video-based structures. Most respondents expressed the need for personal access, personal goals, personal messages, and a personal contact in case of problems or questions (585/817, 71.6%; 546/811, 67.3%; 536/822, 65.2%; 536/822, 65.2%). Memory training, psychological wellbeing, and nutrition were mainly rated as relevant additional content of DIs to promote PA (690/849, 81.2%; 661/845, 78.2%, 619/849, 72.9%).

Conclusion

Community-dwelling older adults may be willing to use DIs to promote PA in the long term, but this study identified particular needs and requirements in terms of design, technological realization, delivery mode, support, and individualization/personalization among the sample. Our results can inform future developments of DIs to promote PA specifically tailored to older adults. However, caution is warranted in interpreting the findings due to the sample's high PA and education levels.

Social Support, Social Participation, and Life Accomplishment of Older Adult Residents of Assisted Living Facilities and Their Adjoining Communities

Objectives: To assess and compare levels of social support (SS), social participation (SP) and life accomplishment (LA) among older adults in some assisted-living facilities (ALFs) and their community-dwelling (CD) peers. Methods: One hundred twenty older adults (54 ALF, 66 CD) from a Nigerian population participated in this cross-sectional survey. The Multidimensional Scale for Perceived Social Support, the Participation Scale and the Life Habit Questionnaires were used to evaluate levels of SS, SP, and LA, respectively. Data was analyzed using descriptive statistics, Mann-Whitney U test and Spearman rank order correlation, at .05 alpha level. Results: Participation restriction (PR) was significantly more prevalent among the ALF group compared to the CD group (χ2 = 12.74; p = .01) but the two groups enjoyed comparable level of SS. LA was significantly better for the CD group in the overall score. LA had significant correlation with PR in both the ALFs (r = -.44; p < .05) and CD (r = -.62; p < .05) group. Conclusions: Older adults in ALFs received moderate SS, had LA, and a high PR, while CD older adults received a high SS and LA but had no PR. The findings implicate that social participation and enhancing community support for older adults may be important for a sustainable community.

Longitudinal associations of housework with frailty and mortality in older adults: Singapore Longitudinal Ageing Study 2

BACKGROUND

Housework may provide a sustainable form of physical activity for older adults and improve health and survival outcomes. Longitudinal studies on associations between housework status over time and health outcomes are lacking. We aim to assess the longitudinal association of intensity and duration of housework with frailty and mortality outcomes.

METHODS

Among 3270 community-dwelling prospective cohort study participants, aged ≥55 years, data on light housework (N=2996) and heavy housework (N=3022) were available at baseline (March 6, 2009, to June 11, 2013) and follow-up at 3 to 5 years later, (January 16, 2013 to August 24, 2018). Median time spent per week on light (≥420min/week) and heavy (>0min/week) household activities at baseline and follow-up were used to categorise individuals into three groups (i) consistent low levels of housework at both baseline and follow-up, (ii) inconsistent high levels of housework at either baseline or follow-up and (iii) consistent high levels of housework at both baseline and follow-up. Baseline and follow-up frailty index >0.10, and all-cause, cancer and cardiovascular mortality from mean 9.5 years follow-up to March 31, 2021. Effect estimates were adjusted for socio-demographics, nutritional risk, lifestyle and other physical activities.

RESULTS

Overall, participants had mean [SD] age, 66.9 [7.8] years; 1916 [62.7%] were female. Participation in high levels of light and heavy housework consistently over time was associated with decreased odds of prefrailty/frailty at follow-up, [OR,0.61;95%CI,0.40-0.94] and [OR,0.56;95%CI,0.34-0.90] respectively, in the older group aged ≥65, compared to participants with consistent low levels of housework at baseline and follow-up. Sex-stratified analysis revealed an association between regular heavy housework participation and lower prevalence of prefrailty/frailty at follow-up in older men but not women [OR,0.31;95%CI,0.13-0.72]. Regular participation in high levels of light housework was associated with 41% lower risk of all-cause mortality [95%CI,0.36-0.96] in women but not in men, and 54% lower risk of cardiovascular mortality [95%CI,0.22-0.96].

CONCLUSIONS

Regular participation in above average levels of light housework is associated with decreased odds of prefrailty/frailty in older adults aged ≥65 years, and all-cause mortality in older women. Heavy housework participation is associated with decreased odds of prefrailty/frailty, especially in older men aged ≥65. Housework may be a meaningful occupation for older adults and should be encouraged for health and wellbeing.

Characterisation of institutionalised Portuguese older adult fallers: is there a place for pharmacist intervention? A preliminary study

Background

Falls are a major public health issue, given their prevalence and social impact. Older adults living in long-term care facilities (LTCF) are at greater risk of injury resulting from a fall due to multiple factors, such as nutritional, functional/cognitive impairment, postural instability, polypharmacy, and the presence of potentially inappropriate medications (PIMs). Medication management in LTCF is complex and often sub-optimal and might be crucial for falls. Pharmacist intervention is important, since they have a unique knowledge of medication. However, studies mapping the impact of pharmaceutical activities in Portuguese LTC settings are scarce.

Objective

This study aims to assess the characteristics of older adult fallers living in LTFCs and examine the relationship between falling and several factors in this population. We also intend to explore the prevalence of PIMs and their relationship with the occurrence of falls.

Methods

The study was conducted in two long-term care facilities for elderly people, in the central region of Portugal. We included patients aged 65 and older with no reduced mobility or physical weakness and with the ability to understand spoken and written Portuguese. The following information was assessed: sociodemographic characteristics, comorbidities, polypharmacy, fear of falling, functional, nutritional and cognitive status. PIMs were evaluated according to the Beers criteria (2019).

Results

A total of 69 institutionalised older adults, 45 women and 24 men, with a mean age of 83.14 ± 8.87 years were included. The prevalence of falls was 21.74% Out of these, 46.67% (n=7) fell once, 13.33% (n=2) fell twice, and 40% (n=6) fell 3 or more times. Fallers were mainly women, had lower levels of education, were well nourished, had moderate to severe levels of dependence, and displayed moderate cognitive impairment. All adult fallers had a fear of falling. The main comorbidities of this population were related to the cardiovascular system. Polypharmacy was present in every patient, and at least one PIM was identified in 88.41% of the subjects. Fear of falling (FOF) and cognitive impairment (in subjects with 1 to 11 years of education) showed statistically significant associations with the occurrence of falls (p=0.005 and p=0.05, respectively). No significant differences were found between fallers and non-fallers for any other factors.

Conclusions

This present study is a preliminary contribution to characterise a group of older adult fallers living in Portuguese LTCFs and demonstrated that fear of falling and cognitive impairment are associated with the occurrence of falls in this population. The high prevalence of polypharmacy and PIMs emphasises the need for tailored interventions featuring the collaboration of a pharmacist to optimise medication management in this population.

Long Term Physical Activity Improves Quality of Life Perception, Healthy Nutrition, and Daily Life Management in Elderly: A Randomized Controlled Trial

Physical activity (PA) is a key element in the management of successful aging. The aim of this paper was to show the effects of PA on the quality of life perception, nutritional status, and daily life management of 178 older adults (aged 63.87 ± 8.17) randomly assigned to an Experimental Group (EG), which performed moderate-to-high intensity aerobic and strengthening training, and a Control Group (CG) which performed low-impact PA, assessed after 6, 12, and 24 months. The Short-Form Health Survey (SF-36), Mini Nutritional Assessment (MNA), and Physical Activity Scale for the Elderly (PASE) were used for the study. In the SF-36 assessment, EG showed a good quality of life perception maintained after 24 months, while CG showed a worsening in the same period (p = 0.018). The EG reported a significant better nutritional status as compared to pre-intervention assessment (p = 0.003) and to CG (p < 0.001). Regarding the PASE, the EG showed a higher level of weekly activities than the CG after 24 months (p = 0.011), while the CG showed a worsening after 12 months (p = 0.008). The prolonged engagement in moderate-to high-intensity PA allowed the maintenance of a good quality of life perception, a good level of nutritional status, and daily life activities.

Does lower quality of life and daily living activity increase nutritional risk of elderly residing in care home facilities?

INTRODUCTION

Aging is a predictable phenomenon that its prevalence is increasing dramatically in the world. There is an association between quality of life, functional independence, and nutritional risk in elderlies, so the aim of the current study is the evaluation of the quality of life and functional independence's effects on nutritional status.

METHODS

A total of 160 elderly people that had a hospitalization for at least 6 months in the care home facilities were selected from 2 care home facility centers to participate in the study. Quantitative and qualitative data were gathered using questionnaires for demographic characteristics, health data, eating habits, quality of life (WHOQOL-BREF), functional assessment (Barthel Index), and mini-nutrition assessment (MNA) throughout the face-to-face interview.

RESULTS

The overall quality of life score, age, weight, and BMI differed significantly between malnourished and well-nourished subjects. Also, the daily living activity score of subjects who were well-nourished was higher than malnourished participants. Higher daily living activity decreased the risk of being malnourished (OR _{malnutrition/well-nourished} = 0.306, P < 0.001). There was also a significant relationship between BMI (OR _{malnutrition/well-nourished} = 0.731, P = 0.001; OR _{at-risk/well-nourished} = 0.786, P = 0.003) and marital status with MNA score (OR _{single/married} = 1.460, P = 0.001 for malnutrition; OR _{single/married} = 1.183, P = 0.004 for being at risk of malnutrition).

CONCLUSIONS

The elderly living in nursing homes are exposed to nutritional risks and mental disorders. So with timely assessment and interventions to improve the quality of life and physical and mental health of elder dwellers, their malnutrition can be prevented.

Psychological status and physical performance are independently associated with autonomic function

Background

Falls among older adults have become a global concern. While previous studies have established associations between autonomic function indicator; heart rate variability (HRV) and blood pressure variability (BPV) with fall recurrence, as well as physical inactivity and psychological disorders as risk factors for falls, the influence of physical activity and psychological status on autonomic dysfunction observed among older fallers has not been adequately investigated. The aim of this study was to evaluate the relationship between psychological disorder and physical performance on the autonomic nervous system (ANS) in older fallers. We hypothesised that older fallers have poorer autonomic function, greater dependency on others and were associated with psychological disorders. Furthermore, we hypothesised that both physical performance and psychological status can contribute to the worsening of the autonomic function among the elderly.

Methods

In this cross-sectional survey, adults aged ≥ 60 years were recruited. Continuous non-invasive BP was monitored over 5 min of supine and 3 min of standing. Psychological status was assessed in terms of depression, anxiety, stress, and concern about falling, while functional status was measured using time-up-and-go, functional reach, handgrip and Lawton’s Instrumental Activities of Daily Life (IADL) scale.

Results

A total of 62 participants were recruited consisting of 37 fallers and 25 non-fallers. Multivariate analysis revealed that Lawton IADL was independently associated with systolic blood pressure variability (SBPV) and diastolic blood pressure variability (DBPV) during both supine (SBPV: r² = 0.080, p = 0.025; DBPV: r² = 0.064, p = 0.046) and standing (SBPV: r² = 0.112, p = 0.008; DBPV: r² = 0.105, p = 0.011), while anxiety score was independently associated with SBPV and DBPV during standing (SBPV: r² = 0.112, p = 0.009; DBPV: r² = 0.105, p = 0.011) as compared to the other parameters.

Conclusion

Our findings suggest that fallers had poorer ANS, greater dependence in IADLs, and were more anxious. IADL dependency and anxiety were the most predictive of autonomic dysfunction, and can be used in practice to identify poor autonomic function for the prevention of falls and cardiovascular diseases among older adults.

The effects of social isolation due to COVID‐19 on the fear of movement, falling, and physical activity in older people

Objective

This study investigates the interaction between fear of movement, fall risk, and physical activity levels in ageing individuals who experienced social isolation during the COVID‐19 pandemic.

Methods

In this descriptive and cross‐sectional study, 254 eligible participants used an online background survey. Individuals’ fear of movement was evaluated by the kinesiophobia causes scale, fall risk by the falls efficacy scale, and physical activity levels by the physical activity scale for the ageing.

Results

The fear of movement had a significant positive interaction on fall risk (β = 0.471, R² = 0.495, p < 0.001). The fall risk had a negative effect on physical activity (β = −1.686, R² = 0.161, p < 0.001). The fear of movement and fall risk explained 15.6% of the change in physical activity levels of ageing individuals (p < 0.001).

Conclusions

These results showed a significant interaction between physical activity levels and fear of movement, with a high fall risk in ageing individuals during the pandemic period.

Investigation of the Effects of COVID-19 on Perception, Attention, Memory, Balance, and Quality of Life in the Elderly

This study was conducted with elderly individuals who had recovered from COVID-19 to investigate the effects of COVID-19 on balance, perception, attention, memory, and quality of life and produce rehabilitative solutions for these problems.

MATERIAL AND METHOD

A total of 45 volunteers older than 65 years who had not had COVID-19 were included in group 1. A total of 45 volunteers older than 65 years who had recovered from COVID-19 were included in group 2 (elderly people who have had COVID-19 at least 6 months ago). After obtaining the individuals' demographic data, we conducted vestibular assessment for balance and administered the Stroop test for attention, the Mini-Mental State Examination (MMSE), the digit span test for short-term memory, and a quality-of-life test.

RESULTS

Mean age of the individuals who had had COVID-19 was 68.24 ± 3.32 years, and the mean age of the individuals who had not had COVID-19 was 68.55 ± 3.34 years. There were statistically significant correlations between the two groups for the Stroop test (P < .05), MMSE (P < .05), the digit span test for perception and attention (P < .05), and the vestibular assessment quality-of-life test (P < .01). Sensory (P < .001), past, present, and future activities (P < .05), social participation (P < .001), and death (P < .05) were found to be significant in the total score (P < .001). The covariance analysis of elderly individuals who had had COVID-19 revealed that they performed significantly worse on the balance, perception, attention, memory, and quality-of-life tests than elderly individuals who had not had COVID-19.

CONCLUSION

The negative effects of COVID-19 were found among elderly individuals older than 65 years. We suggest that telerehabilitation should be developed for elderly people who have recovered from COVID-19 and that its effects investigated.

Social Support, General Self-Efficacy, Fear of Falling, and Physical Activity Among Older Adults in a Middle-Income Country

Objectives: To investigate the levels and interrelationships between fear of falling (FOF), physical activity (PA), social support (SS), and general self-efficacy (GSE) among older adults in a Nigerian community. Methods: This was a cross-sectional survey involving 100 older adults (65.0% females; mean age = 74.25 ± 8.01 years) consecutively recruited from Nnewi community. Participants’ FOF, PA, GSE, and SS were assessed using standardized questionnaires. Data were analyzed using descriptive statistics, Spearman rank order correlation, and structural equation modeling at a 0.05 level of significance. Results: The participants’ mean FOF, PA, GSE, and SS scores were 15.22 ± 7.43 (fearful), 114.76 ± 90.18 (low), 21.64 ± 8.25 (low) and 5.72 ± 1.19 (high) respectively. There were significant correlations between each pair of FOF, PA, GSE, and SS scores of the participants (p < .05). FOF and GSE were significant predictors of PA while GSE and SS were significant predictors of FOF. Conclusion: FOF and SS were high while PA and GSE were low in this sample of Nigerian older adults. Significant correlations existed between FOF, SS, GSE, and PA, with FOF and GSE being predictors of PA while GSE and SS significantly predicted FOF. Measures should be geared towards reducing FOF and improving PA, GSE, and SS in this group.

Lifestyle Behaviors and Quality of Life Among Older Adults After the First Wave of the COVID-19 Pandemic in Hubei China

Background: Older adult quality of life (QoL) is facing huge challenges during the COVID-19 pandemic. New normal lifestyle behaviors, including getting adequate physical activity (PA), consuming sufficient fruits and vegetables (FV) and enacting individual preventive behaviors (frequent hand washing, facemask wearing, and social distancing), as a significant determinant for QoL, have not been adequately addressed in older adults during the pandemic. This study aimed to investigate the characteristics of QoL in Chinese older adults after the first wave of the COVID-19 pandemic in Hubei China. The objective of the study was to examine any associations of lifestyle behaviors with QoL, and to identify the moderating role of socioeconomic indicators in the associations identified. Methods: A cross-sectional study was conducted in Hubei, China, from June 15, 2020, to July 10, 2020. Five hundred sixteen older adults completed an online survey (mean age = 67.6 ± 6.6; 57.9% women). The questionnaire consisted of demographic information, covariates (chronic diseases and infected cases of acquaintances), lifestyle behaviors [PA stage, FV intake (FVI) stage and three preventive behaviors], and QoL. T-tests, ANOVA tests, multiple linear regression models with simple slope analyses were used to test the hypotheses. Results: QoL significantly differed in relation to economic situation, chronic diseases, marital status, education, living situation, age group, and professional status. Participants' economic situation (βaverage vs. below average = 0.17, p < 0.01; βabove average vs. below average = 0.15, p < 0.01), chronic diseases (βyes vs. no = 0.19, p < 0.001), FVI stage (β = 0.21, p < 0.001), and preventive behaviors (β = 0.10, p < 0.05) indicated a significant association with QoL. Education level and economic situation significantly interacted with preventive behaviors on QoL, respectively (βpreventive behaviors × educational level = -1.3, p < 0.01; βpreventive behaviors × economic situation = -0.97, p < 0.05). Conclusions: Findings emphasize the importance of enhancing FVI and preventive behaviors on QoL improvement in older adults during the COVID-19 pandemic. Older adults who are in a lower economic situation with lower education levels should be given priority when implementing interventions to improve preventive behaviors and QoL in older adults.

Increased anxiety about falls and walking ability among community-dwelling Japanese older adults during the COVID-19 pandemic

BACKGROUND

Understanding the physical and mental changes in community-dwelling elderly people is very important during the coronavirus disease 2019 (COVID-19) pandemic when considering preventive measures. The purpose of this study was to clarify the changes of physical function and anxiety for activities of daily living in community-dwelling older adults, focusing on locomotor function during the COVID-19 pandemic.

METHODS

The study participants were 127 older people who participated in successive surveys, in the summers of 2019 and again in 2020, after the state of emergency. The Locomo 25 questionnaire, Geriatric Depression Scale-15 (GDS-15) questionnaire, medical history, and number of people living together were self-reported. The Locomo 25 covers six aspects of physical pain, movement-related difficulty, usual care, daily activity, social activities, and anxiety.

RESULTS

The paired samples t-test revealed that Locomo 25 total scores in 2020 were significantly higher than those in 2019. The GDS-15 score showed no significant difference. The comparison of scores for each item of the Locomo 25 revealed significantly higher scores in 2020 on Q21 ('difficult to perform sports activity', P = 0.0021), Q22 ('restricted from meeting own friends', P < 0.001), Q23 ('restricted from joining social activities', P < 0.001), Q24 ('anxious about falling in own house', P = 0.0023), and Q25 ('anxious about being unable to walk in the future', P = 0.0016).

CONCLUSIONS

About 2 months after declaration of the first state of emergency due to the COVID-19 pandemic in Japan, social activity was severely restricted. Older adults showed almost no changes in body pain and locomotive disabilities, but increases in their anxieties about walking ability and falling were remarkable.

Physical activity analysis for the elderly person in free-living conditions

A growing amount of people are beginning to monitor themselves with the rapid emergence of a wide variety of cost-effective personal sensing instruments. To measure different facets of personal life, innovation helps people better understand their lifestyles, enhance their work quality, or maximize various health factors, allowing free-living. Although vast amounts of raw information on the provisioning and physiological parameters have been obtained much more straightforward, making use of all the information remains a significant task. The article introduces the Physical Activity Analysis Framework (PAAF) for the Elderly Person in Free-Living Conditions. In the framework, the acceleration signals split into overlapped windows and derive information in each frame’s frequency domain. The framework’s sensors sense the activity and evaluate a profound learning structure dependent on each window’s progressive networks. The proposed IoT model has multiple layers separately connected with each sensor, and the critical element integrates the outputs of all sensors for the classification of physical activity. In longer cycles, the model combines the window decision with a substantial increase in its efficiency. The model in the research has been evaluated using labelled free-living pilot data. Eventually, discover the use of the proposed models from a broader lifestyle intervention analysis in unlabeled, free-living data. The results show that the proposed model performs well for both labelled and unlabeled data. The experimental analyses of an older person in living conditions with their daily activities to be monitored via IoT system as Meditation effect analysis ratio is 86.6%, Physical activity ratio is 87.12%, Physical disability ratio is 87.1%, Exercise satisfaction ratio is 85.05%, and Self-efficacy ratio is 93.5%.
