Using the Knowledge to Action framework to improve housing and support for people with Multiple Sclerosis.

Background People with Multiple Sclerosis (MS) have unique housing and support needs that are essential for maintaining independence at home; however, there is limited research to guide the design of community living options for this population. The aim of this study was to examine housing and support needs and preferences of people with MS with the intention to inform the planning of a co-designed intervention based on the study's findings. Methods Using the Knowledge to Action (KTA) framework, quantitative (n =79) and qualitative (n =6) data from people with MS were extracted and integrated from projects completed by the research team that explored the housing and support needs and preferences of people with disability. Results were synthesised and presented to a reference group for validation, contextualisation, and adaptation to the Australian context. Results High physical support needs were common across participants. People most commonly required home modifications to improve accessibility, such as ramps, equipment such as heating and cooling, and assistive technology. Many people required more than 8 hours per day of paid support. Moving into individualised housing facilitated independence and community reintegration. People reported gaps between what they wanted from support workers and what they received, citing individual and systemic barriers. Conclusion People with MS have support needs that require proactive and responsive funding arrangements, housing design and support provision. In line with KTA principles, findings will inform the planning of a co-designed intervention that involves people with lived experience of MS and other stakeholders to influence policy and improve home and living outcomes for this population.

Social support and frailty progression in community-dwelling older adults.

Objectives: Despite the growing evidence regarding the influence of social factors on frailty in older adults, the effect of social support remains unclear. This study aims to assess the association between social support and frailty progression (transition and incidence) in a sample of community-dwelling older adults. Methods: Using a cohort study design, 1,059 older adults from the Berlin Initiative Study were followed up for 2.1 years. Multinomial and logistic regression analyses were performed to assess the association of social support using Oslo Social Support Scale-3 with frailty transition and incidence, respectively. Gender differences were explored using stratified analyses. Results: At baseline, frailty prevalence in the study population [mean (SD) age 84.3 (5.6) years; 55.8% women] reached 33.1% with 47.0, 29.4 and 23.6% of the participants reporting moderate, strong and poor social support, respectively. Over the follow-up period, social support was not significantly associated with the frailty transition categories in the adjusted model. Conversely, the adjusted logistic regression analysis showed that participants with poor social support had twice the odds of becoming frail compared to those with strong social support (OR 2.07; 95% CI 1.08-3.95). Gender-stratified analyses showed comparable estimates to the main analysis but were statistically non-significant. Discussion: Our study results underpin the role of social factors in frailty incidence and highlight social support as a potential target for frailty-preventing interventions in older adults. Therefore, it is important to adopt a biopsychosocial model rather than a purely biomedical model to understand and holistically improve the health of community-dwelling older adults.

Prevalence of intrinsic capacity decline among community-dwelling older adults: a systematic review and meta-analysis.

BACKGROUND: The concept of intrinsic capacity (IC) was introduced to define healthy aging and active aging based on functional capacity, yet there is limited understanding of the risk of IC decline at a population level. AIMS: To consolidate existing evidence for rates of IC decline and risk factors among community-dwelling adults 60 years or older. METHODS: According to the PRISMA guidelines, the literature search was independently conducted by two researchers in 8 databases from inception to January 2024 without language restrictions using combinations of free words and subject words. Qualities of included studies were assessed using Joanna Briggs Institute's (JBI's) critical appraisal checklist for prevalence studies. To pool the data, a random-effect meta-analysis was performed, followed by subgroup analysis and sensitivity analysis. All analyses were performed by Stata14.0. RESULTS: From 1594 records, 15 studies were extracted with 33,070 participants for meta-analysis. The pooled prevalence of IC decline in community settings was 67.8% (95% CI: 57.0-78.5%; P < 0.001). The prevalence of IC decline in China (66.0%; 95% CI: 53.2-78.9%) was found to be slightly lower than in other countries/regions (73.0%; 95% CI: 59.8-86.3%); however, this difference was not statistically significant. Other subgroup analyses revealed no statistically significant differences in prevalence. Age, hypertension, diabetes, gender, education level, living status, smoking, regular exercise, marital status, and osteoarthritis are associated with IC decline. CONCLUSION: More than two-thirds of older adults in the community are affected by IC decline, and age, hypertension, diabetes, female sex, low education level, living alone, smoking, irregular exercise, unmarried, and osteoarthritis are all risk factors for IC decline.

Path analysis of the awareness status and influencing factors of sarcopenia in older adults in the community: based on structural equation modeling.

Background: Sarcopenia is a progressive geriatric syndrome that impacts older adults' quality of life. Insufficient focus has been given to sarcopenia among Chinese residents, resulting in low level of sarcopenia awareness. This study aims to investigate awareness of sarcopenia and its influencing factors and the influencing pathways among older adults in Hangzhou. Methods: A stratified random sample of 942 community-dwelling older adults was evaluated using the SARC-CalF screening tool, along with a questionnaire based on health ecology theory to assess awareness of sarcopenia and its influencing factors and the influencing pathways. Descriptive statistics, linear regression analysis, and path analysis were conducted using SPSS 25.0 and Amos 23.0 to analyze the data. Results: The mean awareness score for sarcopenia was 60.26 ± 7.31. Self-rated physical health, daily intake of high-quality protein, exercise frequency, smoking status, self-efficacy, religious beliefs, social support, education level, occupation, participation in community free medical examinations, and awareness of nutrition policy were all factors affecting scores for sarcopenia awareness (p < 0.05). Except for negative effects observed in social support, smoking status, and self-rated physical health, all others exhibit positive effects. Conclusion: Community healthcare institutions should target populations with low awareness of sarcopenia and focus on these key factors. Diverse health education programs and multi-channel screening activities can promote awareness, guide healthy lifestyles and prevent or delay the onset of sarcopenia in the older.

Perturbation-based balance training of older adults and effects on physiological, cognitive and sociopsychological factors: a secondary analysis from a randomised controlled trial with 12-month follow-up.

BACKGROUND: Perturbation-based balance training (PBT) has shown promising, although diverging, fall-preventive effects; however, the effects on important physical, cognitive and sociopsychological factors are currently unknown. The study aimed to evaluate these effects on PBT at three different time points (post-training, 6-months and 12-months) in community-dwelling older adults compared with regular treadmill walking. METHODS: This was a preplanned secondary analysis from a randomised, controlled trial performed in Aalborg, Denmark, between March 2021 and November 2022. Community-dwelling older adults aged ≥65 were randomly assigned to participate in four sessions (lasting 20 min each) of either PBT (intervention) or regular treadmill walking (control). All participants were assigned to four testing sessions: pretraining, post-training, 6-month follow-up and 12-month follow-up. At these sessions, physical, cognitive and sociopsychological measures were assessed. RESULTS: In total, 140 participants were randomly allocated to either the PBT or control group. Short-term (pretraining to post-training) between-group differences were seen for choice stepping reaction time (-49 ms, 95% CI -80 to -18), dual-task gait speed (0.05 m/s, 95% CI 0.01 to 0.09) favouring the PBT group. However, these improvements were not sustained at the 6-month and 12-month follow-up. No significant between-group differences were found in other physical, cognitive or sociopsychological factors. CONCLUSIONS: This study showed that PBT, in the short term, improved choice stepping reaction time and dual-task gait speed among community-dwelling older adults. Yet, these improvements were not retained for 6- or 12-months. The healthy state of the study's population may have imposed a ceiling effect limiting the ability to show any clinically relevant effects of PBT. TRIAL REGISTRATION NUMBER: NCT04733222.

Prevalence and Diagnostic Agreement of Sarcopenia Based on Handgrip Strength and 5-Time Chair-Stand Test Among Chinese Community-Dwelling Older Adults.

INTRODUCTION: Handgrip strength and the 5-time chair-stand test are the two important muscle strength measures run through the whole sarcopenia diagnosis algorithm. There is a lack of evidence to confirm which muscle strength measures have a higher detection rate of sarcopenia among Chinese older adults, which is a challenge for community workers to choose the muscle strength measures and to identify more sarcopenia in clinical practice. OBJECTIVE: We aimed to investigate the prevalence and diagnostic agreement of sarcopenia based on handgrip strength and the 5-time chair-stand test among Chinese community-dwelling older adults. METHODS: This cross-sectional study sampled 1027 community-dwelling older adults from Hunan, China. We used handgrip strength and the 5-time chair-stand test to assess participants' muscle strength and used gait speed and bioimpedance analysis (BIA) to assess physical performance and skeletal muscle mass, respectively. The kappa values of the agreement test were used to evaluate the agreement of handgrip strength and 5-time chair-stand tests in the assessment of sarcopenia. RESULTS: A total of 1027 participants were included in this analysis including 337 males and 690 females with an average age of 70.35 ± 7.24 years. The prevalence of possible sarcopenia, confirmed sarcopenia and severe sarcopenia based on handgrip strength was 50.8%, 20.3% and 14.5% respectively, while the corresponding prevalence for using the 5-time chair-stand test was 27.6%, 10.8% and 10.9%. The kappa value of the consistency test between handgrip strength and 5-time chair-stand test in the assessment of possible sarcopenia, confirmed and severe sarcopenia was 0.26, 0.51 and 0.62, respectively (p < 0.001 for all). CONCLUSIONS: The prevalence of possible sarcopenia, confirmed sarcopenia and severe sarcopenia based on handgrip strength was significantly higher than that of the 5-time chair-stand test. We recommend handgrip strength as the preferred method of muscle strength measurement for Chinese community-dwelling older adults and use 5-time chair-stand tests when handgrip strength is not available. IMPLICATIONS FOR PRACTICE: The findings provide information and suggestions to healthcare providers for choosing the muscle strength measures to detect more sarcopenia in clinical practice. Compared with the 5-time chair-stand test, handgrip strength has a better performance to identify sarcopenia in Chinese community-dwelling older adults.

Evaluating the health outcomes of aging in place: the role of medicaid aging waiver program on U.S. older adults.

The Medicaid Aging Waiver program (MAW) subsidizes the cost of long-term care (LTC) at home or in communities to satisfy older people's increasing desire to age in place. The MAW program might be health improving for older people by allowing them to age at home. However, less quality and quantity of home-based care comparing to nursing home care could offset some of the potential benefits. I use policy expenditure across states over time linked with detailed health information from the Health and Retirement Study (HRS) to identify the associated effects of MAWs on health outcomes of older adults who are at risk of needing LTC and who are resources constrained to be potentially eligible for Medicaid. Overall, the findings suggest that the MAW program is beneficial to health: a $1,000 increase in MAW spending for each older person results is associated with a 1.4 percent improvement in self-reported health status, a 1.5 percent reduction in functional mobility limitations, a 1.6 percent decrease in Instrumental Activities of Daily Living (IADL) limitations, and a 1.7 percent improvement in negative psychological feelings. For older people who are most likely not eligible for MAWs, such as those who are wealthy or in good health and do not require LTC, these health-improving effects have not been observed.

Multimorbidity patterns and the risk of falls among older adults: a community-based study in China.

BACKGROUND: Due to the high prevalence of multimorbidity and realistic health service demands for fall prevention, there is growing interest in the association between multimorbidity and falls. Our study aimed to identify multimorbidity patterns among Chinese older adults and explore the association between multimorbidity patterns and falls. METHODS: Data from 4,579 Chinese community-dwelling older adults was included in this analysis. Information regarding falls and 10 chronic conditions was collected. An exploratory factor analysis was performed to determine multimorbidity patterns. Regression models were fitted to explore the associations of individual chronic disease or multimorbidity patterns with falls. RESULTS: Among 4,579 participants, 368 (8.0%) were defined as fallers, including 92 (2.0%) frequent fallers, and multimorbidity affected 2,503 (54.7%) participants. Older adults with multimorbidity were more likely to be fallers [odds ratio (OR) = 1.3, P = 0.02] and frequent fallers (OR = 1.7, P = 0.04). Three multimorbidity patterns were identified (i.e., cardiovascular-metabolic diseases, psycho-cognitive diseases and organic diseases), and the associations between psycho-cognitive diseases/organic diseases and prevalent falls or frequent falls were found to be significant. CONCLUSIONS: The psycho-cognitive disease pattern and organic disease pattern are significantly associated with falls. Therefore, more attention should be paid to patients with psycho-cognitive diseases and timely, targeted diagnostic and treatment services should be provided in fall prevention.

Identification and prediction of frailty among community-dwelling older Japanese adults based on Bayesian network analysis: a cross-sectional and longitudinal study.

BACKGROUND: Frailty is a multifactorial syndrome; through this study, we aimed to investigate the physiological, psychological, and social factors associated with frailty and frailty worsening in community-dwelling older adults. METHODS: We conducted a cross-sectional and longitudinal study using data from the "Community Empowerment and Well-Being and Healthy Long-term Care: Evidence from a Cohort Study (CEC)," which focuses on community dwellers aged 65 and above in Japan. The sample of the cross-sectional study was drawn from a CEC study conducted in 2014 with a total of 673 participants. After excluding those who were frail during the baseline assessment (2014) and at the 3-year follow-up (2017), the study included 373 participants. Frailty assessment was extracted from the Kihon Checklist, while social relationships were assessed using the Social Interaction Index (ISI). Variable selection was performed using Least Absolute Shrinkage and Selection Operator (LASSO) regression and their predictive abilities were tested. Factors associated with frailty status and worsening were identified through the Maximum-min Hillclimb algorithm applied to Bayesian networks (BNs). RESULTS: At baseline, 14.1% (95 out of 673) participants were frail, and 24.1% (90 out of 373) participants experienced frailty worsening at the 3-years follow up. LASSO regression identified key variables for frailty. For frailty identification (cross-sectional), the LASSO model's AUC was 0.943 (95%CI 0.913-0.974), indicating good discrimination, with Hosmer-Lemeshow (H-L) test p = 0.395. For frailty worsening (longitudinal), the LASSO model's AUC was 0.722 (95%CI 0.656-0.788), indicating moderate discrimination, with H-L test p = 0.26. The BNs found that age, multimorbidity, function status, and social relationships were parent nodes directly related to frailty. It revealed an 85% probability of frailty in individuals aged 75 or older with physical dysfunction, polypharmacy, and low ISI scores; however, if their social relationships and polypharmacy status improve, the probability reduces to 50.0%. In the longitudinal-level frailty worsening model, a 75% probability of frailty worsening in individuals aged 75 or older with declined physical function and ISI scores was noted; however, if physical function and ISI improve, the probability decreases to 25.0%. CONCLUSION: Frailty and its progression are prevalent among community-dwelling older adults and are influenced by various factors, including age, physical function, and social relationships. BNs facilitate the identification of interrelationships among these variables, quantify the influence of key factors. However, further research is required to validate the proposed model.

Relationship between triglyceride-glucose index and cognitive function among community-dwelling older adults: a population-based cohort study.

Background: The global increase in the aging population presents considerable challenges, particularly regarding cognitive impairment, a major concern for public health. This study investigates the association between the triglyceride-glucose (TyG) index, a measure of insulin resistance, and the risk of cognitive impairment in the elderly. Methods: This prospective cohort study enrolled 2,959 participants aged 65 and above from the 2015 and 2020 waves of the China Health and Retirement Longitudinal Study (CHARLS). The analysis employed a logistic regression model to assess the correlation between the TyG index and cognitive impairment. Results: The study included 2,959 participants, with a mean age of 71.2 ± 5.4 years, 49.8% of whom were female. The follow-up in 2020 showed a decrease in average cognitive function scores from 8.63 ± 4.61 in 2015 to 6.86 ± 5.45. After adjusting for confounding factors, a significant association was observed between TyG index quartiles and cognitive impairment. Participants in the highest quartile (Q4) of baseline TyG had a higher risk of cognitive impairment compared to those in the lowest quartile (Q1) (odds ratio [OR]: 1.97, 95% confidence intervals [CI]: 1.28-2.62, P<0.001). Conclusion: The study highlights a significant connection between elevated TyG index levels and cognitive impairment among older adults in China. These findings suggest that targeted interventions to reduce the TyG index could mitigate cognitive impairment and potentially lower the incidence of dementia.

Development of a self-assessment tool to address the functioning of community-dwelling older adults in general practice: a validation study of the EFA23 questionnaire.

BACKGROUND: Multimorbidity is increasingly prevalent among ageing patients, leading to reduced daily functioning. To address the challenges posed by multimorbidity in older adults, a person- and context-centred approach is needed. This study aimed to develop a questionnaire as a self-assessment tool for older adults focusing on functioning in general practice based on the International Classification of Functioning, Disability and Health (ICF). METHODS: A mixed-methods approach was employed in the development and validation of the German EFA23 (Erfassung Funktionaler Gesundheit im Alter - 23 Fragen; Assessing Functional Health in Old Age - 23 questions) questionnaire. Based on an ICF subset developed in a preparatory phase and consensus study, questionnaire items were formulated and tested in a qualitative pretest, followed by a validation study. A workshop with general practitioners (GPs) was held to develop a supplementary manual for GPs on how to interpret the questionnaire results and discuss them with the patients. RESULTS: A total of 69 items were developed and tested in the qualitative pretest with 15 respondents, resulting in 37 items for the validation study. The validation study, involving 237 older adults, showed the presence of one significant principal component. It demonstrated good internal consistency (Cronbach's alpha = 0.967) and construct validity, showing positive correlations with established assessment tools. Descriptive statistics showed differences between the means of self-assessment by patients and an external GP assessment. The final EFA23 questionnaire consists of 23 items assessing limitations in functioning. CONCLUSIONS: The EFA23 questionnaire can be used as a valid self-assessment instrument to measure functioning in older adults, supporting a person- and context-centred approach in general practice.

Relationship between malnutrition according to the global leadership initiative on malnutrition criteria and oral health among community-dwelling elderly aged 85 years and older: a cross-sectional study.

BACKGROUND: A new diagnostic criterion for malnutrition, the Global Leadership Initiative on Malnutrition (GLIM) criteria, has been proposed. Despite a recognized link between malnutrition and oral health, further clarification is needed regarding this association when using the GLIM criteria. This study examined the association between malnutrition and oral health in community-dwelling older adults aged ≥ 85. METHODS: This study was conducted using data from the Tokyo Oldest Old Survey on Total Health study, and altogether 519 participants ≥ 85 years were enrolled. Malnutrition was assessed using the GLIM criteria. Oral health information, on the number of teeth, maximum occlusal force (MOF), saliva production, denture-related questions (dissatisfaction and frequency of use), dental visit history in the past year, whether participants enjoyed meals, and oral-related quality of life was assessed using the Geriatric Oral Health Assessment Index (GOHAI) were collected. MOF was assessed the average values of three measurements and lower tertile by sex as decline in MOF. For GOHAI, the score for each items (Q1-Q12) was also evaluated, and further, the decline in each item (score: 1-2 points on a 5-point scale) was assessed as a "problem with each items." Oral health factors differing between those with and without malnutrition were analyzed. For differing items, malnutrition risk was evaluated using Cox regression. RESULTS: Eighty-nine (17.1%) participants experienced malnutrition. Significant differences were observed in the decline in MOF, enjoyment of meals, individual scores for Q2, Q4, and Q6, and the problem with Q3, Q6, Q7, and Q11. Cox regression analysis showed that decline in MOF (odds ratio [OR]: 1.728, 95% confidence interval [CI]: 1.010-2.959), enjoyment of meals (OR: 0.502, 95% CI: 0.289-0.873), problem with Q3 (OR: 5.474, 95% CI: 1.301-23.028), Q6 (OR: 5.325, 95% CI: 1.026-27.636), and Q7 (OR: 2.867, 95% CI: 1.397-5.882) were associated with ORs of malnutrition. CONCLUSION: Decline in MOF, enjoyment of meals, swallowing problem (problem with Q3), limit contact due to oral condition (problem with Q6), and esthetics problem (problem with Q7) were associated with malnutrition as assessed using the GLIM criteria.

Physical frailty and oral health as risk factors for low bone density in community-dwelling residents.

This study aimed to explore the association between bone mineral density and physical frailty including nutrition, muscle mass, and oral function. We included participants aged 35-80 years and examined their bone mineral density, serum albumin level, body composition, and variance of hue (VOH) of two-colored gum. We also used the geriatric oral health assessment index (GOHAI). These data were used to calculate the geriatric nutritional risk index (GNRI) and skeletal muscle index (SMI). Multinomial logistic regression was performed to assess the relationship between GNRI, SMI, VOH, GOHAI, and bone mineral density after adjusting for comorbidities, including hypertension, diabetes mellitus, and previous bone fracture. We included 228 participants and classified their bone mineral density as normal, osteopenic, or osteoporotic. Older age (odds ratio (OR) 1.15, 95% confidence interval (CI) [1.08, 1.23]), low GNRI (OR 0.90, 95% CI [0.83, 0.98]), low SMI (OR 0.43, 95% CI [0.27, 0.68]), and high VOH (OR 1.08, 95% CI [1.01, 1.17]) were significantly associated with osteoporosis. Older age (OR 1.08, 95% CI [1.04, 1.11]) and low GNRI (OR 0.93, 95% CI [0.87, 0.99]) were significantly associated with osteopenia. GNRI, SMI, and VOH were significantly associated with osteoporosis among male participants. Although the multinomial logistic regression analysis indicated that GNRI, SMI, VOH, and GOHAI were not significantly associated with osteoporosis or osteopenia among female participants, the demographic distribution showed that older age, low GNRI, and low SMI were significantly associated with bone mineral density decline. Physical frailty, including nutritional decline, muscle mass loss, and poor oral status, is associated with low bone density. This easy-to-use tool can be used to detect osteoporosis early and to prevent osteoporosis and osteoporosis-related fractures.

Independent Supported Housing vs institutional housing rehabilitation settings for non-homeless individuals with severe mental illness - longitudinal results from an observational study.

BACKGROUND: Most individuals with severe mental illness (SMI) strongly prefer independent living over living in an institution. Independent Supported Housing (ISH) provides housing rehabilitation for persons with SMI in their accommodations. However, most individuals who need housing rehabilitation live in institutional housing settings (housing rehabilitation as usual: HAU). We investigated which housing rehabilitation setting is effective on which variable in the long term to support service users to form an informed preference for either housing rehabilitation setting. METHODS: We conducted a two-year longitudinal observational non-inferiority study to test the effectiveness of ISH in improving participants' social inclusion, quality of life, emotional social support, capabilities, symptom severity, functioning, service utilisation and costs. Participants were assessed at baseline and after six, twelve, and 24 months. Mixed effects models were computed to test between-group and within-group effects. RESULTS: The study included 83 participants in ISH (n = 31) and HAU (n = 52) housing rehabilitation settings with a mean age of 36.2 years. Most participants were male (64%) and had a primary psychotic or schizophrenic (35%) or an affective diagnosis (24%). During the study, ISH participants significantly improved their quality of life (ß = 0.54; 95% CI: 0.26 to 0.82), symptoms (ß = -0.32; 95% CI: -0.60 to -0.03), and capabilities (ß = 4.46; 95% CI: 0.14 to 8.77) and decreased psychiatric hospitalisations (p = 0.04). HAU participants improved their quality of life (ß = 0.40; 95% CI: 0.12 to 0.69). Housing and rehabilitation support costs were almost half with ISH than with HAU. CONCLUSION: ISH has been shown to be much less expensive than HAU and was associated with several improvements like reduced psychiatric hospitalisations and improved quality of life. Therefore, our findings strongly argue for a preference-driven provision of housing rehabilitation services and to end the institutionalisation of persons with SMI. TRIAL REGISTRATION: The study was registered on December 04, 2018, at ClinicalTrials.gov (NCT03815604).

In-Shoe Sensor Measures of Loading Asymmetry during Gait as a Predictor of Frailty Development in Community-Dwelling Older Adults.

Clinical walk tests may not predict the development of frailty in healthy older adults. With advancements in wearable technology, it may be possible to predict the development of frailty using loading asymmetry parameters during clinical walk tests. This prospective cohort study aimed to test the hypothesis that increased limb loading asymmetry predicts frailty risk in community-living older adults. Sixty-three independently ambulant community-living adults aged ≥ 65 years were recruited, and forty-seven subjects completed the ten-month follow-up after baseline. Loading asymmetry index of net and regional (forefoot, midfoot, and rearfoot) plantar forces were collected using force sensing insoles during a 10 m walk test with their maximum speed. Development of frailty was defined if the participant progressed from baseline at least one grading group of frailty at the follow-up period using the Kihon Checklist. Fourteen subjects developed frailty during the follow-up period. Increased risk of frailty was associated with each 1% increase in loading asymmetry of net impulse (Odds ratio 1.153, 95%CI 1.001 to 1.329). Net impulse asymmetry significantly correlated with asymmetry of peak force in midfoot force. These results indicate the feasibility of measuring plantar forces of gait during clinical walking tests and underscore the potential of using load asymmetry as a tool to augment frailty risk assessment in community-dwelling older adults.

Perceived Benefit and Satisfaction With a Tablet Computer and an Emergency Smartwatch by Older Adults and Their Relatives: Prospective Real-World Pilot Study.

Background: Assistive technologies (ATs) have the potential to promote the quality of life and independent living of older adults and, further, to relieve the burden of formal and informal caregivers and relatives. Technological developments over the last decades have led to a boost of available ATs. However, evidence on the benefits and satisfaction with ATs in real-world applications remains scarce. Objective: This prospective, real-world, pilot study tested the perceived benefit and satisfaction with different ATs in the real-world environment. Methods: Community-dwelling adults aged ≥65 and their relatives tested a tablet computer with a simplified interface or a smartwatch with programmable emergency contacts for 8 weeks in their everyday life. Perceived benefits and satisfaction with ATs were assessed by all older adults and their relatives using different assessment tools before and after the intervention. Outcome measures included the Technology Usage Inventory, Quebec User Evaluation of Satisfaction with Assistive Technology 2.0, and Canadian Occupational Performance Measure. Results: A total of 17 older adults (tablet computer: n=8, 47% and smartwatch: n=9, 53%) and 16 relatives (tablet computer: n=7, 44% and smartwatch: n=9, 56%) were included in the study. The number of participants that were frail (according to the Clinical Frailty Scale) and received care was higher in the smartwatch group than in the tablet computer group. Older adults of the smartwatch group reported higher technology acceptance (Technology Usage Inventory) and satisfaction (Quebec User Evaluation of Satisfaction with Assistive Technology 2.0) scores than those of the tablet computer group, although the differences were not significant (all P>.05). In the tablet computer group, relatives had significantly higher ratings on the item intention to use than older adults (t12.3=3.3, P=.006). Identified everyday issues with the Canadian Occupational Performance Measure included contact/communication and entertainment/information for the tablet computer, safety and getting help in emergency situations for the smartwatch, and the usability of the AT for both devices. While the performance (t8=3.5, P=.008) and satisfaction (t8=3.2, P=.01) in these domains significantly improved in the smartwatch group, changes in the tablet computer group were inconsistent (all P>.05). Conclusions: This study highlights the remaining obstacles for the widespread and effective application of ATs in the everyday life of older adults and their relatives. While the results do not provide evidence for a positive effect regarding communication deficits, perceived benefits could be shown for the area of safety. Future research and technical developments need to consider not only the preferences, problems, and goals of older adults but also their relatives and caregivers to improve the acceptability and effectiveness of ATs.

Cardiovascular disease risk factors and frailty syndrome in community-dwelling older adults: Results from the Amirkola Health and Aging Project Cohort Study.

BACKGROUND: Early diagnosis and control of risk factors affecting frailty syndrome (FS) in older adults may lead to changes in the health/disease process, prevention of disability and dependency in the older adults, and reduction of health care costs and mortality rates. The aim of this study was to determine the predictive role of CVD risk factors and FS in community-dwelling older adults of Amirkola city in Iran. METHODS: This descriptive-analytic cross-sectional study is part of the second phase of the Amirkola Health and Aging Project (AHAP) cohort study conducted since 2011 on all individuals ≥ 60 years in the city of Amirkola in northern Iran. Totally, 1000 older adults were included in the study and divided into three groups: frail (n = 299), pre-frail (n = 455), and non-frail (n = 246) older adults. In the present study, age ≥ 60 years, female sex, fasting blood sugar (FBS) ≥ 126 mg/dl, affected diabetes mellitus (DM), body mass index (BMI) ≥ 27 kg/m², waist circumference (WC) or abdominal obesity > 102 cm in men and > 88 cm in women, low-density lipoprotein (LDL) > 100 mg/dl, triglyceride > 150 mg/dl, cholesterol > 200 mg/dl, high-density lipoprotein (HDL) < 40 mg/dl and blood pressure (BP) > 90/140 mmHg, uric acid > 7 mg/dl and a positive smoking history were considered CVD risk factors. RESULTS: The results showed that with each centimeter increase in WC, the odds of frailty compared with non-frailty was 79% higher, and the odds of frailty compared with pre-frailty was 1.43 times higher in older adults. In addition, the prevalence of pre-frailty compared with non-frailty, pre-frailty, and non-frailty was 10.59 times, 6.08 times, and 73.83 times higher in older individuals > 84 years old, respectively. The results of the present study indicated that the prevalence of pre-frailty compared with non-frailty, frailty compared with pre-frailty, and frailty compared with non-frailty was 2.86 times, 3.01 times, and 14.83 times higher in older adults women, respectively. The comparison between frail and non-frail groups represented that in DM older adults, the prevalence of frailty compared with non-frailty was 1.84 times higher and that of frailty compared with pre-frailty was 98% higher. The older adults with an FBS ≥ 126 mg/dl were 53% more likely to become frail, and with each unit increase in uric acid, the odds of becoming frail increased 2.05 times compared with non-frail older adults, and pre-frail compared with non-frail increased 99%. CONCLUSION: The results demonstrated that CVD risk factors predictive of FS included central obesity, age > 84 years, female sex, DM, FBS ≥ 126, and uric acid > 7. This problem highlights the need for preventive strategies in the older adults who are simultaneously vulnerable to CVD and frailty.

Moving the needle on implementing fall prevention programs in Saudi Arabia: assessing knowledge and perceptions of fall risk among community-dwelling older women.

BACKGROUND: Saudi Arabia, like many nations globally, is experiencing a demographic shift towards an aging population. With this demographic shift, falls and the fear of falling (FOF) emerge as serious public health concerns among community-dwelling older adults. Addressing misconceptions and enhancing awareness regarding fall risks among older adults holds significant importance, offering insights for informing targeted interventions and enhancing well-being. This study aimed to examine knowledge and perceptions of fall risk among community-dwelling older women in Saudi Arabia. METHODS: A cross-sectional study was conducted with 150 Saudi older women, with a mean age (SD) of 63.98 (4.90) years. Participants completed questionnaires assessing fall history, fall knowledge, fall perception, the Falls Efficacy Scale-International (FES-I), Timed Up and Go (TUG), and the Barthel Index. Fall knowledge and perception were assessed using previously constructed statements translated into Arabic and carried out in interviewer-administered forms. RESULTS: Nearly half of the participants reported experiencing at least one fall in the previous 12 months. Despite good knowledge of falls, some gaps were identified, particularly regarding the awareness of social isolation as a consequence of falls. Participants demonstrated positive perceptions towards fall prevention programs but also highlighted misconceptions regarding aging and falls. FOF was prevalent, with higher levels identified among participants without a history of falls. CONCLUSION: Multidimensional strategies are needed to address falls and FOF among community-dwelling older women in Saudi Arabia. Leveraging existing knowledge and perceptions towards fall prevention and implementing evidence-based interventions can reduce the burden of falls and enhance health outcomes in older adults. Future research should focus on diverse samples and evaluate the feasibility of implementing fall prevention interventions within Saudi Arabia's healthcare systems.

Social support and sleep quality in people with schizophrenia living in the community: the mediating roles of anxiety and depression symptoms.

Introduction: Research has demonstrated that higher social support is associated with better psychological health, quality of life, cognition, activities of daily living, and social participation, but the relationship between social support and sleep quality remains unknown. This study aims to investigate the mediating effects of anxiety and depression in the relationship between social support and sleep among community-dwelling patients with schizophrenia. Method: Purposive sampling was used to collect face-to-face data from 1,107 community-dwelling patients with schizophrenia in Chengdu, Sichuan Province, China, between April and July 2023. The Athens Insomnia Scale (AIS) was used to assess sleep quality; the Generalized Anxiety Disorder 7-item scale (GAD-7) was utilized to evaluate anxiety symptoms; and the Patient Health Questionnaire-9 (PHQ-9) was employed to assess depressive symptoms. The mediating effect of anxiety and depression symptoms was assessed using the bootstrap method via Model 6 (Serial multiple mediator model) of the SPSS PROCESS macro. Results: Among the 1,107 participants, the proportions of people with schizophrenia experiencing anxiety, depressive symptoms, and poor sleep quality were 22.8, 37.7, and 42.1%, respectively. Mediation analyses indicated that although social support had no direct effect on sleep quality, anxiety and depressive symptoms fully mediated the relationship between social support and sleep quality. Conclusion: Patients with schizophrenia experience low levels of social support and poor sleep quality. To enhance the sleep quality of individuals with schizophrenia, all levels of society (government, medical institutions, and communities) must pay more attention to mental health. Implementing diverse intervention measures to strengthen social support and improve symptoms of anxiety and depression should be considered. This approach may potentially lead to an improvement in sleep quality among individuals with schizophrenia.

Effects of physical exercise intervention on improving physical functioning and quality of life among geriatric population: A systematic review of randomized controlled trials.

OBJECTIVE: To assess the effectiveness of exercise intervention on elderly population's physical functioning and quality of life. Methods: The systematic review was conducted in line with the Preferred Reporting Items for Systematic Reviews and Meta- Analyses guidelines, and comprised research on Cochrane Library, PubMed, Physiotherapy Evidence Database and Web of Science for randomised controlled trials published in the English language from January 2012 to December 2021. The trials included comprised individuals of either gender aged ≥60 years who were either community-dwelling elderly or patients living in residential facilities who could walk independently with or without assistive devices. Key words used for the search included age, exercise, physical function, quality of life and cognition. A 10-point scale from the Physiotherapy Evidence Database was used for methodological evaluation. RESULTS: Of the 1050 studies initially found, 14(1.33%) were analysed in detail. All 14(100%) included multi-component exercise interventions, like aerobic, strength and balance, 4(28.6%) trials included cognition and quality of life as well. Only 1(7.14%) trial showed little or no improvement in terms of quality of life. Of the 2(14.3%) studies that reported the effects of exercise on falls, 1(50%) found positive impact of exercise interventions, while 1(50%) showed no improvement on the risk of fall and psychosocial factors related to fall. Overall, 9(64.3%) trials investigated the effects of exercise training on several aspects of mobility, and showed marked improvement in mobility. Also, 8(57.14%) trials studied the effect of exercise intervention on balance performance, and 1(12.5%) of them showed no effect on balance. Of the 9(64.3%) trials investigating the effects of exercise intervention on muscle strength, 5(55.5%) reported increase in muscle strength. Conclusion: Multi-component exercises were found to have a positive impact on functional and psychosocial health of geriatric population.
