Frailty and risk of falls, fracture, and mortality in older women: the study of osteoporotic fractures

The Opinions of Turkish Older Adults Related to Frailty: A Qualitative Study

Frailty is a geriatric syndrome characterized by decreased daily living activity, weight loss, weakness, and dependency caused by the cumulative decline in many physiological systems over the life span. This study examined older adults' perceptions of frailty. The study used a descriptive qualitative design. Data were collected using semistructured interviews with 14 older adults admitted to the geriatrics outpatient clinic in one Turkish institution from September to December 2019. The interviews were transcribed and analyzed using the MAXQDA data analysis software. Codes were combined into themes. The respondents were aged 74.5 ± 8.7 years. Two themes emerged from the qualitative data: (i) the conceptualization of frailty; and (ii) coping with frailty. Some of the participants self-identified as frail, a natural consequence of aging. Another group of participants emphasized the feelings of hopelessness and hopefulness in coping with frailty in their remaining lives. This study provides insights into older Turkish adults' opinions regarding frailty, including the development of frailty and its relationship with health status and daily life. This understanding may be used to detect frailty in older adults and to improve frail older adults' care interventions.

Cost-Effectiveness of Multifactorial Interventions in Preventing Falls among Elderly Population: A Systematic Review

Objective:

To review the cost-effectiveness of multifactorial interventions to prevent falls in elderly people.

Methods:

In this systematic review, the databases including PubMed via MEDLINE, Web of Science, Embase, Scopus, Cochrane Library and Google Scholar (from 1st January 2000 to 30^th February) were used. All pre-reviewed articles related to cost-effectiveness analysis of multifactorial interventions to prevent falls in elderly were included in this paper and congresses abstracts were excluded. Descriptive statistics were used for quantitative data and content-analysis method to analyze qualitative data.

Results:

Out of the 456 articles, 19 were finally included in the study. Eighteen articles were conducted in High-Income Countries (HICs) and 16 were at the community level. Medical visits consultation and education were the most common interventions. Most studies were cost-effectiveness and using the Randomized Control Trial (RCT) methods. A fall of prevention costs ranged from $ 272 to $ 987. Incremental Cost-Effectiveness Ratio (ICER) interventions also ranged from the US $ 120,667 to the US $ 4280.9.

Conclusion:

The results show that despite the high effectiveness of multifactorial interventions to prevent elderly falls, the cost of the interventions are high and they are not very cost-effective. It would be better to design and implement multifactorial interventions with low cost and high effectiveness that are appropriate for each country.

Assessing frailty indicators in the context of psychiatric disorder: A Delphi consensus study

OBJECTIVES

Substantial construct overlap exists between indicators of frailty and symptoms of some psychiatric disorders. This study aimed to gain consensus of expert academic opinion on the potential impact of psychiatric illness on frailty assessment and how best to conceptualise and measure frailty indicators in the context of psychiatric symptoms.

DESIGN

A classic Delphi approach was employed across two studies to achieve consensus: The first-round questionnaire consisted of open-ended questions, analysed through content analysis. The results informed the development of statements for participants to rate their agreement with in subsequent Delphi rounds. Statements with ≥66% agreement were accepted. Delphi Study 1 recruited experts in frailty assessment (n = 13) and Delphi Study 2 recruited experts in frailty and psychiatric disorder (n = 8). Experts were recruited globally.

RESULTS

Overall, 40% of Delphi Study 1 statements and 43% of Delphi Study 2 statements were accepted. Primarily, consensus was reached for statements concerning the influence of depression/anxiety on frailty assessment and potential methods of conceptualising and measuring frailty indicators in the context of psychiatric symptoms. Little consensus was reached concerning the ease and importance of differentiating between frailty indicators and psychiatric assessment criteria with substantial overlap.

CONCLUSIONS

The Delphi studies provide a novel exploration and consensus of expert academic opinions concerning the assessment of frailty indicators in the context of psychiatric symptoms. The results will inform future research into the adaptation or development of a frailty assessment tool specifically for use in older adult psychiatric populations.

Outcomes of Femoral Neck Fracture Treated With Hip Arthroplasty in Solid Organ Transplant Patients

Background

Solid organ transplant (SOT) patients have increased risk of complications, infection, and mortality after elective total hip arthroplasty (THA). The study aims to compare SOT recipients' clinical outcomes to a matched group of nontransplant patients after nonelective THA and hemiarthroplasty for acute femoral neck fracture (FNF).

Methods

A retrospective review identified 31 SOT patients undergoing hip arthroplasty (24 hemiarthroplasty and 7 THA) for FNF and were matched 1:1 to non-SOT patients based on age, sex, body mass index, surgical procedure, and year of surgery. Patient survivorship, perioperative outcomes, complications, and reoperations were compared. The mean follow-up was 3 years.

Results

The estimated survivorship free from mortality for SOT and non-SOT patients at 1- year was not different (77% and 84%, respectively, P = .52). The 90-day readmission rate was significantly higher with 8 (26%) in the SOT cohort and none in the non-SOT group (P < .01). Major medical complications occurred in 16% of SOT patients compared to 5% in controls (P = .21). Three (10%) reoperations/revisions were required for SOT patients and none in non-SOT group (P = .24).

Conclusion

SOT recipients undergoing nonelective hip arthroplasty for FNF demonstrated increased readmission rates compared to matched controls. For this rare clinical scenario, diligent perioperative care by surgeons and multidisciplinary transplant specialists is necessary to mitigate increased risk of SOT patients.

Midlife Cardiovascular Health and Robust versus Frail Late-Life Status: The Atherosclerosis Risk in Communities (ARIC) Study

BACKGROUND

We examined the relationship of midlife cardiovascular health (CVH) with late-life robustness among men and women and the impact of survivorship bias on sex-differences in robustness.

METHODS

Prospective analysis of 15,744 participants aged 45-64 (Visit 1 median age: 54 years, 55% female, 27% Black) in 1987-1989 from the population-based ARIC Study. CVH was operationalized according to the Life's Simple 7 (LS7) metric of health behaviors (smoking, weight, physical activity, diet, cholesterol, blood pressure, and glucose); each behavior was scored as ideal (2 points), intermediate (1 point), or poor (0 points) and summed. Late-life robust/pre-frail/frailty was defined at Visit 5 (2011-2013). Multinomial regression estimated relative prevalence ratios (RPR) of late-life robustness/pre-frailty/frailty/death across overall midlife LS7 score and components, for the full Visit 1 sample. Separate analyses considered Visit 5 survivors only.

RESULTS

For each one-unit greater midlife LS7 score, participants had a 37% higher relative prevalence of being robust versus frail (overall RPR=1.37, [95% CI: 1.30-1.44]; women=1.45 [1.36-1.54]; men=1.24 [1.13-1.36]). Among the full Visit 1 sample, women had a similar one-level higher robustness category prevalence (RPR=1.35 [95% CI: 1.32-1.39]) than men (RPR=1.31 [95% CI: 1.27-1.35]) for every one-unit higher midlife LS7 score. Among survivors, men were more likely to be robust than women at lower LS7 levels; differences were attenuated and not statistically different at higher midlife LS7 levels.

CONCLUSIONS

Midlife CVH is positively associated with robustness in late-life among men and women. Accounting for mortality in part explains documented sex-differences in robustness across all levels of LS7.

Urinary urgency acts as a source of divided attention leading to changes in gait in older adults with overactive bladder

AIMS

There is a well-recognised but unexplained association between lower urinary tract symptoms including urgency and urgency incontinence and falls in older people. It has been hypothesised that urinary urgency acts as a source of divided attention, leading to gait changes which increase falls risk. This study aimed to assess whether urinary urgency acts as a source of divided attention in older adults with overactive bladder (OAB).

METHODS

27 community-dwelling adults aged 65 years and over with a clinical diagnosis of OAB underwent 3-Dimensional Instrumented Gait Analysis under three conditions; bladder empty, when experiencing urgency, and when being distracted by the n-back test. Temporal-spatial gait and kinematic gait data were compared between each condition using repeated measures ANOVA.

RESULTS

Gait velocity decreased from 1.1ms-1 in the bladder empty condition to 1.0ms-1 with urgency and 0.9ms-1 with distraction (p = 0.008 and p<0.001 respectively). Stride length also decreased, from 1.2m to 1.1m with urgency and 1.0m with distraction (p<0.001 for both). The presence of detrusor overactivity did not influence these results (p = 0.77).

CONCLUSIONS

In older adults with OAB, urinary urgency induced similar changes in gait to those caused by a distracting task. These gait changes are associated with increased fall risk. This may be part of the explanation for the association between falls and lower urinary tract symptoms in older people. Future research should examine the effect of pharmacological treatment of OAB on gait and on the effect of dual-task training on gait when experiencing urgency.

Interactive effect of sarcopenia and falls on vertebral osteoporotic fracture in patients with rheumatoid arthritis

Patients with rheumatoid arthritis (RA) had higher incidences of sarcopenia, falls, osteoporosis, and vertebral osteoporotic fractures (VOPF). Sarcopenia was associated with longer disease duration, higher disease activity, and more severe RA. The interactive effect of sarcopenia and falls was associated with a higher risk of VOPF in patients with RA.

PURPOSE

Whether sarcopenia and falls are a risk factor for vertebral fracture in RA patients has not been demonstrated. This study aimed to explore the incidence of vertebral osteoporotic fracture (VOPF) and its relationship with sarcopenia and falls in RA patients.

METHODS

A total of 474 RA patients and 156 controls were enrolled in this study. Anteroposterior and lateral X-ray examinations of the vertebral column (T4-L4) were used for the semiquantitative assessment of VOPF. Bone mineral density was measured by dual-energy X-ray absorptiometry. Skeletal muscle mass was measured by direct segmental multifrequency bioelectrical impedance analysis (DSM-BIA method).

RESULTS

RA patients had an increased risk of sarcopenia (62.4% vs 9.0%, x² = 47.478, P < 0.001), falls (30.2% vs 3.2%), osteoporosis (OP) (33.5% vs 12.8%, x² = 134.276, P < 0.001), and VOPF (20.3% vs 3.8%, x² = 47.478, P < 0.001) than controls. Patients with sarcopenia were more likely to have VOPF than RA without sarcopenia (24.0% vs 14.0%, x² = 6.802, P = 0.009). RA with sarcopenia and prior falls had the highest incidences of VOPF (36.7%). Older age (OR = 1.056, P < 0.001, 95% CI 1.030-1.083), falls (OR = 2.043, P = 0.003, 95% CI 1.238-3.371), OP (OR = 1.819, P = 0.034, 95% CI 1.046-3.163), and usage of glucocorticoids (GCs) (OR = 1.862, P = 0.022, 95% CI 1.093-3.172) were risk factors for VOPF in RA patients, while a higher skeletal muscle index (SMI) was a protective factor (OR = 0.754, P = 0.038, 95% CI 0.578-0.984) for VOPF in RA patients.

CONCLUSIONS

The interactive effect of sarcopenia and falls is associated with a higher risk of VOPF in patients with RA.

Falls prevention at GP practices: a description of daily practice

BACKGROUND

General practitioners (GPs) can be considered the designated professionals to identify high fall risk and to guide older people to fall preventive care. Currently it is not exactly known how GPs treat this risk. This study aims to investigate GPs' daily practice regarding fall preventive care for frail older patients.

METHODS

Sixty-five GPs from 32 Dutch practices participated in this study for a period of 12 months. When a GP entered specific International Classification of Primary Care-codes related to frailty and/or high fall risk in their Electronic Health Records, a pop-up appeared asking "Is this patient frail?". If the GP confirmed this, the GP completed a short questionnaire about patient's fall history and fear of falling (FOF), and the fall preventive care provided.

RESULTS

The GPs completed questionnaires regarding 1394 frail older patients aged ≥75. Of 20% of these patients, the GPs did not know whether they had experienced a fall or not. The GPs did not know whether a FOF existed in even more patients (29%). Of the patients with a fall history and/or a FOF (N = 726), 37% (N = 271) received fall preventive care. Two main reasons for not offering fall preventive care to these patients were: I) the patient finds treatment too intensive or too much of a hassle (37%), and II) the GP identified a high fall risk but the patient did not acknowledge this (14%). When patients were treated for high fall risk, the GP and the physiotherapist were the most frequently involved health care providers. The involved health care providers most often treated mobility limitations, cardiovascular risk factors, and FOF.

CONCLUSIONS

The results from this study show that GPs were frequently not aware of their frail patient's fall history and/or FOF and that the majority of the frail older patients with a fall history and/or FOF did not receive fall preventive care. Developing systematic screening strategies for the primary care setting enhancing the identification of high fall risk and the provision of fall preventive care may improve patients' quality of life and reduce health care costs.

Fifteen years change in acute management of hip fracture patients: 1-year mortality calls for improvements

INTRODUCTION

Over the past two decades, the average age of hip fractured patients has increased, patients are increasingly fragile and their management is more complex. Most of the literature suggest that care improvement lowered short-term mortality but there is no clear evidence whether mid- and long-term mortality rates are improving. The aim of this study was to evaluate the variations in comorbidities in hip fractured patients over 15 years, the changes in mortality and identify the predictive factors for mortality for identifying the patients at higher risk.

MATERIALS AND METHODS

Hip fractured patients admitted in hospital in 2000-2001 (192 patients) and 2015-2016 (323 patients) were retrospectively reviewed. Demographic, clinical and management data from the two cohorts were compared. Thirty-day and 1-year mortality were calculated and compare between the two cohorts. A multivariate logistic regression model were performed to identify the most significant predictors of mortality.

RESULTS

After fifteen years, mean age of hip fracture patients increased by 2.6 years with a 31% increase in comorbidity. The most prevalent comorbidities were hypertension, COPD, diabetes, arrhythmia, renal impairment and dementia. In the 2015-2016 cohort, the age-adjusted mortality at 30 days significantly declined compared to the 2000-2001 cohort (respectively 6.9% vs. 12.5%) but the age-adjusted mortality at 1-year was equivalent. Older age, reduced mobility, higher comorbidity, lateral fractures and male sex were significant risk factors for reduced survival time CONCLUSIONS: After 15 years, there was a significant improvement in 30-days mortality in hip fractured patients despite their increase in comorbidities but this advantage was not observed in 1-year mortality. This suggests the need to implement targeted and longer-term care support for males, older patients and those with greater comorbidities which are at higher risk.

Health Literacy and Frailty in Community-Dwelling Older Adults: Evidence from a Nationwide Cohort Study in South Korea

Health literacy is closely associated with poor health outcomes and mortality. However, only a handful of studies have examined the association between health literacy and frailty status. The current study used data from a nationwide sample of Korean adults aged 70-84 collected from 10 cities, each of which represents a different region of South Korea (n = 1521). We used the propensity score matching (PSM) method to minimize the potential selection bias and confounding factors that are present in observational studies. After PSM, demographic and health-related characteristics between the limited health literacy (n = 486) and the nonlimited health literacy (n = 486) groups were not significantly different. Multinomial logistic regression analyses were conducted for the PSM-matched sample to examine the association between health literacy and frailty outcomes, where the robust group was set as a reference. Limited health literacy significantly increased the risk of pre-frailty (RRR = 1.45, p = 0.02) and frailty (RRR = 2.03, p = 0.01) after adjusting for demographic and health-related factors. Our findings underscore the need to foster health literacy programs and provide preliminary evidence to inform tailored intervention programs so that we might attenuate the risk of frailty in the older population.

Clusters of Physical Frailty and Cognitive Impairment and Their Associated Comorbidities in Older Primary Care Patients

(1) Objectives: We aimed to identify clusters of physical frailty and cognitive impairment in a population of older primary care patients and correlate these clusters with their associated comorbidities. (2) Methods: We used a latent class analysis (LCA) as the clustering technique to separate different stages of mild cognitive impairment (MCI) and physical frailty into clusters; the differences were assessed by using a multinomial logistic regression model. (3) Results: Four clusters (latent classes) were identified: (1) highly functional (the mean and SD of the “frailty” test 0.58 ± 0.72 and the Mini-Mental State Examination (MMSE) test 27.42 ± 1.5), (2) cognitive impairment (0.97 ± 0.78 and 21.94 ± 1.95), (3) cognitive frailty (3.48 ± 1.12 and 19.14 ± 2.30), and (4) physical frailty (3.61 ± 0.77 and 24.89 ± 1.81). (4) Discussion: The comorbidity patterns distinguishing the clusters depend on the degree of development of cardiometabolic disorders in combination with advancing age. The physical frailty phenotype is likely to exist separately from the cognitive frailty phenotype and includes common musculoskeletal diseases.

[Characteristics of geriatric and somatic status in patients with osteoporosis]

BACKGROUND

Older adults with osteoporosis (OP) and high risk of falls are the most vulnerable group of patients with respect to the development of fractures. Falls and fractures in elderly patients with OP are associated with geriatric syndromes and worse functional status.

AIM

To аssess comorbidity and geriatric status in elderly and senile patients with and without OP.

MATERIALS AND METHODS

The study included 607 patients over 60 years of age hospitalized in the geriatric department. According to the presence of OP, the patients were divided into 2 groups: group 1 - patients with OP (n=178, 29.3%), group 2 - patients without OP (n=429, 70.7%). All patients underwent a general clinical study, an assessment of comorbidity -according to the Charlson index, and a comprehensive geriatric score.

RESULTS

OPs had 178 (29.3%) patients, more often these were women. 55.6% of patients with OP were disabled. Age--related diseases such as Alzheimer's disease, Parkinson's disease, osteoarthritis, anemia, thyroid disease, varicose veins were significantly more common in patients with OP. With almost all of these diseases, a univariate analysis revealed an association with OP. Geriatric syndromes such as frailty, hypodynamia, malnutrition, polypharmacy, urinary incontinence were significantly more common in group 1 patients. Patients with OP were more likely to live alone and use mobility aids compared to patients without OP.The univariate analysis demonstrated that OP is associated (OR 1.54 to 2.00) with frailty, hypodynamia, the use of aids in movement, sleep disorders, sensory vision deficiency, urinary incontinence. The Functional status of patients with OP was worse compared to patients without OP. Patients with OP suffered more fractures, and vertebral fractures were significantly more frequent.

CONCLUSION

Patients with OP have a high comorbidity, a burdened geriatric status. In elderly patients, it is necessary not only to screen and diagnose OP, to assess the risk of 10-years probability of major pathological fractures using the FRAX algorithm, but also to conduct a comprehensive geriatric assessment to diagnose geriatric syndromes that weaken the course of OP and lead to more serious consequences.

Adverse Health Effects of Frailty: Systematic Review and Meta-Analysis of Middle-Aged and Older Adults With Implications for Evidence-Based Practice

BACKGROUND

Scholars have noted that frailty easily leads to functional deterioration and proneness to complications. Little literature addresses the stages of frailty in middle-aged and older adults and the effects of frailty on overall health.

AIMS

This study explores the effect of different stages of frailty on the prospective health (falls, bone fractures, disability, dementia, hospitalization, and death) of middle-aged and older adults. In addition, different frailty indicators were compared to determine their usefulness in predicting future adverse health outcomes.

METHODS

The authors of this study separately reviewed and extracted data from the literature obtained while searching the following keywords: "frailty" OR "frail" and "fall" OR "disability" OR "fracture" OR "hospitalization" OR "mortality" OR "cognitive function" "dementia" OR "Alzheimer's disease" and "middle-aged people" OR "older people" OR "elderly" OR "geriatric" OR "senior." The literature search was performed from January 2001 to November 2019 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Specifically, we performed a systematic literature search in multiple databases-Embase, PubMed, MEDLINE, CINAHL, and Cochrane Library-and analyzed all obtained literature results using a random-effects model.

RESULTS

We collected a total of 29 prospective studies for the systematic literature review and meta-analysis. The main results indicated that the frail groups had significantly higher risks of adverse health effects (falls, bone fractures, disability, dementia, hospitalization, and death) than the robust or prefrail groups.

LINKING EVIDENCE TO ACTION

Frailty is a crucial healthcare topic among geriatric syndromes. Considering that older adults with frailty are most likely to develop severe adverse health outcomes, professional nursing personnel should assess frailty among middle-aged and older adults and offer relevant care strategies to reduce the adverse effects of frailty in this population.

Urine and Serum Electrolytes and Biochemical Values Associated with Osteoporosis in Premenopausal and Postmenopausal Women: A Longitudinal and Cross-Sectional Study Using Korean Genome and Epidemiology Study (KoGES) Cohort

Osteoporosis is a major public health concern, especially in women. This study aims to identify early biomarkers from biochemical measurements of serum and urine for recognizing the development of osteoporosis and osteopenia in premenopausal and postmenopausal women. From the Korean Genome and Epidemiology Study (KoGES) cohort, longitudinal study participants with normal bone density were enrolled and assessed for the association of baseline clinical and biochemical factors with osteoporosis development over 4 years. In addition, a cross-sectional study between normal bone density and osteopenia/osteoporosis was conducted to validate the risk factors found in the longitudinal cohort. Of the 5272 female participants in the KoGES cohort, 813 women (501 premenopausal and 312 menopausal) who had normal bone density at baseline were included in the longitudinal study. During the 4 years of follow-up, 64 patients developed osteoporosis and 354 developed osteopenia. In a multivariate logistic regression analysis, serum calcium and urine uric acid levels were significantly associated with elevated osteoporosis risk in premenopausal and postmenopausal women, respectively (risk of osteoporosis by serum calcium levels in premenopausal women: 4.03 (1.09–14.93), p = 0.037; risk of osteoporosis by urine uric acid levels in postmenopausal women: 24.08 (1.79–323.69), p = 0.016). For the cross-sectional study, serum and urine parameters were compared between women with osteopenia or osteoporosis at baseline and those with normal bone density. Urine uric acid levels were found to be significantly higher in both premenopausal and postmenopausal women with bone loss than in women with normal bone density (p < 0.001 and p = 0.004, respectively). Uric acid level in urine may be an early marker for the development of osteoporosis in women, especially after menopause.

Gender Differences in Chronic Obstructive Pulmonary Disease Symptom Clusters

Purpose

Previous research has indicated that female and male patients may experience different levels of symptoms. However, no studies of chronic obstructive pulmonary disease (COPD) patients have compared the number and types of symptom clusters identified in male and female patients. Therefore, the purpose of this study was to investigate gender differences in symptom clusters among COPD patients.

Patients and Methods

A total of 371 eligible patients were enrolled in the study. We assessed nine COPD symptoms, namely, dyspnea, cough, sputum, chest tightness, sleep quality, fatigue, frailty, anxiety, and depression. Exploratory factor analyses were used to explore the underlying clusters of the COPD symptoms.

Results

Underlying the nine symptoms, female patients had 2 clusters, and male patients had 3 clusters. Specifically, the three general symptoms poor sleep, fatigue, and frailty loaded on the same symptom cluster with anxiety and depression in female patients, while the same 3 general symptoms loaded on the same symptom cluster with chest tightness and dyspnea in male patients. Moreover, cough and sputum not only were more common in male patients but also loaded together on a separate symptom cluster.

Conclusion

Our findings suggest that in order to improve fatigue, frailty, and poor sleep quality, symptom management strategies should more closely address anxiety and depression in female patients as well as chest tightness and dyspnea in male patients. Smoking cessation is particularly important in male COPD patients because they account for a much higher proportion of smokers and are more likely to have cough and sputum. These findings signify the importance of identifying and implementing gender-tailored symptom management strategies to relieve symptom burden in COPD patients to enhance their quality of life.

Multidimensional sleep health and subsequent health-care costs and utilization in older women

STUDY OBJECTIVES

Determine the association of poor multidimensional sleep health with health-care costs and utilization.

METHODS

We linked 1,459 community-dwelling women (mean age 83.6 years) participating in the Study of Osteoporotic Fractures Year 16 visit (2002-2004) with their Medicare claims. Five dimensions of sleep health (satisfaction, daytime sleepiness, timing, latency, and duration) were assessed by self-report. The number of impaired dimensions was expressed as a score (range 0-5). Total direct health-care costs and utilization were ascertained during the subsequent 36 months.

RESULTS

Mean (SD) total health-care costs/year (2017 dollars) increased in a graded manner across the sleep health score ranging from $10,745 ($15,795) among women with no impairment to up to $15,332 ($22,810) in women with impairment in three to five dimensions (p = 0.01). After adjustment for age, race, and enrollment site, women with impairment in three to five dimensions vs. no impairment had greater mean total costs (cost ratio [CR] 1.34 [95% CI = 1.13 to 1.60]) and appeared to be at higher risk of hospitalization (odds ratio (OR) 1.31 [95% CI = 0.96 to 1.81]). After further accounting for number of medical conditions, functional limitations, and depressive symptoms, impairment in three to five sleep health dimensions was not associated with total costs (CR 1.02 [95% CI = 0.86 to 1.22]) or hospitalization (OR 0.91 [95% CI = 0.65 to 1.28]). Poor multidimensional sleep health was not related to outpatient costs or risk of skilled nursing facility stay.

CONCLUSIONS

Older women with poor sleep health have higher subsequent total health-care costs largely attributable to their greater burden of medical conditions, functional limitations, and depressive symptoms.

Prevalence of frailty and associated factors among Saudi community-dwelling older adults: a cross-sectional study

Background

Prevalence of frailty has been previously established in different Western countries; however, the prevalence and the burden of in the aging populations of Saudi Arabia has not been examined. Therefore, the aim of this study was to examine the prevalence of frailty, and associated factors among Saudi older population.

Methods

The study included a total of 486 community-dwelling elderly adults aged 60 years and over living in the Riyadh area. This study took place from August 2019 to June 2020. The prevalence of frailty was determined using the Fried’s frailty phenotype. Association between sociodemographic features and clinical factors and frailty was estimated by Odds Ratio and confidence intervals (OR, IC 95%) using a multinomial logistic regression model.

Results

The overall prevalence of pre-frailty and frailty were 47.3 and 21.4%, respectively. The following factors were associated with being frail: age (OR: 6.92; 95%CI 3.11–15.41); living alone (OR: 2.50; 95%CI: 1.12–5.59); had more chronic conditions (OR: 1.96; 95%CI: 1.16–3.30); and cognitive impairment (OR: 7.07; 95%CI: 3.92–12.74).

Conclusions

The Compared with other populations, the prevalence of frailty and pre-frailty in the Riyadh region of Saudi Arabia was high. The implications of frailty in this population should be discussed in future study.

Examining the links between regular leisure-time physical activity, sitting time and prefrailty in community-dwelling older adults

AIMS

To examine the relationship between leisure-time physical activity, sitting time and prefrailty in community-dwelling older adults.

DESIGN

Cross-sectional study.

METHODS

Between February and July 2019, 539 individuals over age 60 were recruited in northern Taiwan. Demographic, medical history, physical activity and frailty data were analysed using descriptive statistics, chi-square tests and logistic regression.

RESULTS

The prevalence of prefrailty was 24.4%; 33.2% had regular leisure-time physical activity, and 14.7% reported >6 hrs daily sitting time. Compared with individuals having regular leisure-time physical activity and shorter sitting times (daily average ≤6 hrs), those having no regular leisure-time physical activity and also shorter sitting times (adjusted OR, 1.80; 95% CI, 1.12, 2.92), or those also having regular leisure-time physical activity but longer sitting times (adjusted OR, 4.42; 95% CI, 2.22, 8.79) had an increased prefrailty risk.

CONCLUSIONS

Having no regular leisure-time physical activity or longer sitting times is associated with a higher risk of prefrailty. For sedentary older adults to prevent prefrailty, they can become more active, sit less or better yet, commit to both.

The effects of teriparatide and bisphosphonates on new fractures in postmenopausal women with osteoporosis: A protocol for systematic review and meta-analysis

BACKGROUND

To systematically evaluate the efficacy of teriparatide and bisphosphonates in preventing fractures in postmenopausal women with osteoporosis.

MATERIALS AND METHODS

We performed a systematic search of PubMed, Embase, and the Cochrane Library for randomized controlled trials (RCTs) that compared teriparatide and bisphosphonates for osteoporosis treatment. Searches were performed without language restrictions and included studies from beginning of time to March 2019. Two authors independently screened and extracted the selected article. The quality of the included studies was evaluated using the Cochrane system evaluation method. Data were extracted and analysed using RevMan 5.2 software.

RESULTS

Nine RCTs were included for a total of 2990 postmenopausal women with osteoporosis. Of these, 1515 patients were treated with teriparatide and 1475 were treated with bisphosphonates. After pooling the data of 9 studies, there were significant differences between teriparatide and bisphosphonates [relative risk (RR): 0.61, 95% confidence interval (CI) (0.51, 0.74)] in the prevention of fractures according to different follow-up durations (P < .05), whatever alendronate [RR: 0.51, 95% CI (0.27, 0.95)] and other bisphosphonates [RR: 0.63, 95% CI (0.51, 0.77)]. In addition, we found significant differences between teriparatide and bisphosphonates in the prevention of vertebral fractures [RR: 0.47, 95% CI (0.35, 0.64)] and non-vertebral fractures [RR: 0.76, 95% CI (0.58,0.99)]. There were no significant differences in adverse effects between teriparatide and bisphosphonates [RR: 0.89, 95% CI (0.76, 1.03)].

CONCLUSIONS

Based on the results of our meta-analysis, teriparatide was better than bisphosphonates in preventing fractures in postmenopausal women with osteoporosis both in the short-term and long-term follow-up periods. Teriparatide was superior to bisphosphonates in preventing vertebral and non-vertebral fractures. These drugs did not differ in terms of their adverse effects. More high-quality studies are needed to compare other factors such as costs and adverse reactions.

Longitudinal Impact of Frailty States and Sleep Duration on Subsequent Depressive Symptoms of Older Adults

OBJECTIVES

To determine the effects of baseline and changes in frailty states on subsequent depressive symptoms, and whether sleep duration would modify these effects.

DESIGN

Prospective, cohort study.

SETTING

The 2011 baseline and 2013 follow-up waves of the China Health and Retirement Longitudinal Study (CHARLS).

PARTICIPANTS

Community-dwelling old adults who were aged 60 or above at baseline and participated in the 2011 and 2013 waves of the CHARLS (N = 5,026).

MEASUREMENTS

Frailty was measured using the physical frailty phenotype (PFP) scale. Levels of depressive symptoms were measured by the 10-item Center for Epidemiologic Studies Depression Scale (CES-D). Using the generalized estimating equations (GEE), the effects of baseline and transitions in frailty states were examined on subsequent depressive symptoms, adjusting for a range of confounding variables.

RESULTS

Baseline prefrail (b = 0.97, P < .05) and frail states (b = 0.35, P < .05) were associated with higher subsequent level of depressive symptoms 2 years later. Within individuals who were robust at baseline, transitioning into prefrail/frail (b = 3.04, P < .001) was associated with a higher subsequent level of depressive symptoms, and this association was accelerated by short sleep duration. Within individuals who were prefrail at baseline, transitioning into frail (b = 1.76, P < .001) was associated with higher subsequent levels of depressive symptoms, and this association was stronger among those who reported short sleep duration.

CONCLUSION

Baseline and transitions in frailty states were significantly related with higher subsequent levels of subsequent depressive symptoms. Short sleep duration significantly moderated the effects of baseline or transitions of frailty on subsequent depressive symptoms. Targeted interventions could be implemented to improve sleep quality for prefrail and frail older adults.

Association between mortality risk and the number, location, and sequence of subsequent fractures in the elderly

The mortality risk showed a positive correlation as the number of subsequent fractures increased. Hip fracture showed the greatest association with mortality risk, followed by vertebral fracture. For the combination of hip and vertebral fracture, a hip fracture after a vertebral fracture showed the highest mortality risk.

INTRODUCTION

It is unclear whether subsequent fractures or a certain location and sequence of subsequent fractures are associated with mortality risk in the elderly. We aimed to investigate the relationship between subsequent fractures and mortality risk.

METHODS

Using the Korean National Health Insurance Research Database, we analyzed the cohort data of 24,756 patients aged > 60 years who sustained fractures between 2002 and 2013. Cox regression was used to assess the mortality risk associated with the number, locations, and sequences of subsequent fractures.

RESULTS

Mortality hazard ratios (HRs) for women and men were shown to be associated with the number of subsequent fractures (one, 1.63 (95% confidence interval [CI], 1.48-1.80) and 1.42 (95% CI, 1.28-1.58); two, 1.75 (95% CI, 1.47-2.08) and 2.03 (95% CI, 1.69-2.43); three or more, 2.46(95% CI, 1.92-3.15) and 1.92 (95% CI, 1.34-2.74), respectively). For women, the mortality risk was high when hip (HR, 2.49; 95% CI, 1.80-3.44) or vertebral (HR, 1.40; 95% CI, 1.03-1.90) fracture occurred as a second fracture. Compared with a single hip fracture, there was a high mortality risk in the group with hip fracture after the first vertebral fracture (HR, 2.90; 95% CI, 1.86-4.54), followed by vertebral fracture after the first hip fracture (HR, 1.90; 95% CI, 1.12-3.22).

CONCLUSION

The mortality risk showed a positive correlation as the number of subsequent fractures increased. Hip fracture showed the greatest association with mortality risk, followed by vertebral fracture. For the combination of hip and vertebral fracture, a hip fracture after a vertebral fracture showed the highest mortality risk.

Contrast sensitivity is associated with frailty

PURPOSE

Using data from the Malaysian Elders Longitudinal Research (MELoR), this study investigated the association between visual function (visual acuity and contrast sensitivity) and frailty in a group of urban-dwelling older adults.

METHODS

This was a cross-sectional study. 1332 participants aged ≥ 55 years were selected by random sampling from the parliamentary electoral register. Only 1274 participants completed the frailty assessment and 1278 participants completed the contrast sensitivity assessment. Impaired vision was defined as a Snellen visual acuity of worse than 6/12 in the better eye. Poor contrast sensitivity was defined as a score on the Pelli Robson chart of lower than 1.65. Frailty was defined with the Fried's phenotype criteria. Inter-group comparisons were determined with the independent T-test for continuous variables and the Pearson's Chi-squared test for categorical variables. The odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the cross-sectional association between frailty and visual function.

RESULTS

The mean age of participants was 68.8 ± 7.5 years, of which 58.1% (774) were women. Impaired vision and poor contrast sensitivity were present in 187 (14%) and 271 (21.2%) subjects respectively. 73 (5.8%) individuals were classified as frail, 1161 (91.0.%) pre-frail, and 40 (2.8%) non-frail. There was no significant difference in frailty phenotypes between those with good and impaired vision (p = 0.241). Fried's component of handgrip strength, gait speed and exhaustion were significantly better in those with good visual function (p < 0.05). Participants with poor contrast sensitivity were significantly more likely to be frail (OR: 5.34, p = 0.004).

CONCLUSION

Poor contrast sensitivity was significantly associated with frailty. This highlights the importance of incorporating assessment of contrast sensitivity in those at risk of frailty.

The Association of Muscle Mass Measured by D3-Creatine Dilution Method With Dual-Energy X-Ray Absorptiometry and Physical Function in Postmenopausal Women

BACKGROUND

The D3-creatine (D3Cr) dilution method provides a direct measure of skeletal muscle. The aim of this study was to compare the association of D3Cr muscle mass with lean body mass (LBM) measured by dual-energy x-ray absorptiometry (DXA) and examine its relation with physical function in postmenopausal women.

METHODS

Seventy-four community-dwelling women (mean age 82.3 ± 5.4) participated in this pilot study from the Buffalo, New York clinical site of the Women's Health Initiative (WHI). Participants attended a clinic visit which included anthropometric measures, blood draw, DXA scan, measures of physical function, and initiated the D3Cr protocol. Physical function was evaluated using hand grip strength, short physical performance battery (SPPB), and RAND-36 physical function scale. Descriptive statistics and logistic regression models were used to examine the associations of D3Cr muscle mass with functional outcomes.

RESULTS

D3-creatine muscle mass was moderately correlated with DXA LBM (r = 0.50) and DXA appendicular lean mass (ALM) (r = 0.50). Individuals with high D3Cr muscle mass (%) had higher physical function compared to individuals with low muscle mass (%), indicated by high scores on SPPB (odds ratio [OR] = 5.24; 95% confidence interval [CI]: 1.40, 19.58). We observed stronger relationships between high D3Cr and physical function than either DXA LBM (OR = 3.40; 95% CI: 0.88, 13.11) or DXA ALM (OR = 4.15; 95% CI: 1.10, 15.68) and physical function.

CONCLUSIONS

Our findings provide strong preliminary data for the associations of D3Cr muscle mass with measures of physical function in older women. These findings support and extend prior work on D3Cr muscle mass in older men.

The Relations Among Physical Indicators, Cognitive Status, Community Participation, and Depression of the Frail Male Elderly in Taiwan

This study explored the basic attributes, physiological indices, cognitive states, and community participation of older male outpatients with frailty for predicting depression. Questionnaires were collected using purposive sampling from a medical clinic in a teaching hospital in northern Taiwan. One hundred and ninety frail men enrolled as participants. The results revealed that older male adults with frailty, the age, residence, income, self-reported health status, alcohol consumption, total instrumental activities of daily living (IADL) scores in physiological indices, IADL grouping, cognitive state score, each Mini-Mental State Examination category, and involvement and dedication scores exhibited statistical differences from depression scores. Depression determinants, such as an excellent and normal self-reported health status and IADL total score, could predict the depression status of male older adults with frailty. Nursing personnel should assess the self-reported health status and self-care ability of male older adults with frailty early to prevent or delay geriatric depression.

Validity and reliability of the self-rated fall risk questionnaire in older adults with osteoporosis

BACKGROUND

Several risk assessments have been developed to evaluate fall risk in older adults, but it has not been conclusively established which of these tools is most effective for assessing fall risk in this vulnerable population. Recently, the U.S. Centers for Disease Control and Prevention (CDC) developed the self-rated Fall Risk Questionnaire (self-rated FRQ), a 12-item questionnaire designed to screen older adults who are at risk of falling and has been widely used in many centers. This study aimed to determine the validity and reliability of the self-rated FRQ in older adults with osteoporosis.

METHODS

This prospective study was conducted at the Department of Orthopedic Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand from December 2019 to March 2020. Sixty-eight men or postmenopausal women aged > 65 years who were diagnosed with osteoporosis either by bone mineral density T-score or by occurrence of fragility fracture were evaluated with the self-rated FRQ, the Thai falls risk assessment test (Thai-FRAT), the timed get-up-and-go test (TUG test), the Berg Balance Scale (BBS), and the 5 times sit-to-stand test (5TSTS test). Validity of the self-rated FRQ was assessed by evaluating the correlations (r) between the self-rated FRQ score and the scores from the other four assessments. Reliability of the self-rated FRQ was evaluated by measuring test-retest reliability and internal consistency.

RESULTS

The self-rated FRQ was moderately strongly correlated with the BBS, TUG test, and 5TSTS test (r = 0.535 to 0.690; p < 0.001), and fairly correlated with the Thai-FRAT (r = 0.487; p < 0.001). Test-retest reliability of the self-rated FRQ was high, with a Kappa of 1. Internal consistency of the self-rated FRQ was excellent (Cronbach's alpha: 0.936).

CONCLUSIONS

The self-rated FRQ was found to be a valid and reliable tool for evaluating fall risk in older adults with osteoporosis. Since assessment of fall risk requires a multifaceted measurement tool, the self-rated FRQ is an appropriate tool that can be integrated into the fall risk assessment algorithm in older adults with osteoporosis.

The Importance of Taking a Patient-Centered, Community-Based Approach to Preventing and Managing Frailty: A Public Health Perspective

Across the world, life expectancy is increasing. However, the years of life gained do not always correspond to healthy life years, potentially leading to an increase in frailty. Given the extent of population aging, the association between frailty and age and the impact of frailty on adverse outcomes for older people, frailty is increasingly being recognized to be a significant public health concern. Early identification of the condition is important to help older adults regain function and to prevent the negative outcomes associated with the syndrome. Despite the importance of diagnosing frailty, there is no definitive evidence or consensus of whether screening should be routinely implemented. A broad range of screening and assessment instruments have been developed taking a biopsychosocial approach, characterizing frailty as a dynamic state resulting from deficits in any of the physical, psychological and social domains, which contribute to health. All these aspects of frailty should be identified and addressed using an integrated and holistic approach to care. To achieve this goal, public health and primary health care (PHC) need to become the fulcrum through which care is offered, not only to older people and those that are frail, but to all individuals, favoring a life-course and patient-centered approach centered around integrated, community-based care. Public health personnel should be trained to address frailty not merely from a clinical perspective, but also in a societal context. Interventions should be delivered in the individuals' environment and within their social networks. Furthermore, public health professionals should contribute to education and training on frailty at a community level, fostering community-based interventions to support older adults and their caregivers to prevent and manage frailty. The purpose of this paper is to offer an overview of the concept of frailty for a public health audience in order to raise awareness of the multidimensional aspects of frailty and on how these should be addressed using an integrated and holistic approach to care.

Neighborhood Characteristics and Frailty: A Scoping Review

BACKGROUND AND OBJECTIVES

Frailty is highly prevalent in later life and associated with early mortality and adverse health outcomes. The neighborhood has been identified as an important contributor to individual health, and neighborhood characteristics may contribute to frailty development. A scoping review was conducted of the peer-reviewed literature to better understand how physical and social neighborhood characteristics contribute to frailty.

RESEARCH DESIGN AND METHODS

Following an established scoping review methodology, we searched four peer-reviewed databases for relevant studies published from January 1, 2008, to December 31, 2018. Data extracted from studies included study characteristics, operationalization of neighborhood, the conceptual model of the neighborhood-frailty relationship, operationalization of frailty, and study findings for associations among neighborhood variables and frailty indicators.

RESULTS

A total of 522 articles were identified and 13 articles were included in the final data charting. Existing studies suggest that neighborhood characteristics are associated with frailty in later life. Few studies articulated a conceptual model identifying exact mechanisms through which neighborhood factors affected frailty. Studies designs were mostly cross-sectional. Longitudinal studies did not measure neighborhood characteristics over time. Studies varied considerably in how they operationalized the neighborhood. Frailty was most commonly assessed using a 5-point phenotype or a frailty index approach.

DISCUSSION AND IMPLICATIONS

Findings indicate that research on the relationship between neighborhood characteristics and frailty is an emerging area of inquiry. Additional studies are needed to more definitely explicate mechanisms through which neighborhoods contribute to, or protect older adults from, frailty.

Falls, frailty, and metabolic syndrome in urban dwellers aged 55 years and over in the Malaysian elders longitudinal research (MELoR) study - a cross-sectional Study

OBJECTIVES

While metabolic syndrome, falls, and frailty are common health issues among older adults which are likely to be related, the potential interplay between these three conditions has not previously been investigated. We investigated the relationship between metabolic syndrome with falls, and the role of frailty markers in this potential relationship, among community-dwelling older adults.

METHODS

Data from the first wave Malaysian Elders Longitudinal Research (MELoR) study comprising urban dwellers aged 55 years and above were utilized. Twelve-month fall histories were established during home-based, computer-assisted interviews which physical performance, anthropometric and laboratory measures were obtained during a hospital-based health check. Gait speed, exhaustion, weakness, and weight loss were employed as frailty markers.

RESULTS

Data were available for 1415 participants, mean age of 68.56 ± 7.26 years, 57.2% women. Falls and metabolic syndrome were present in 22.8% and 44.2%, respectively. After adjusting for age, sex, and multiple comorbidities, metabolic syndrome was significantly associated with falls in the sample population [odds ratio (OR): 1.33, 95% confidence interval (CI): 1.03; 1.72]. This relationship was attenuated by the presence of slow gait speed, but not exhaustion, weakness, or weight loss.

CONCLUSION

Metabolic syndrome was independently associated with falls among older adults, and this relationship was accounted for by the presence of slow gait speed. Future studies should determine the value of screening for frailty and falls with gait speed in older adults with metabolic syndrome as a potential fall prevention measure.

Risk factors for recurrent falls in older adults: A systematic review with meta-analysis

Older adults who fall recurrently (i.e., 2 or more falls/year) are at risk of functional decline and mortality. Understanding which risk factors for recurrent falls are most important will inform secondary fall prevention strategies that can reduce recurrent falls risk. Thus, we conducted a systematic review with meta-analysis to determine the relative risk of recurrent falls for different types of falls risk factors. MEDLINE, EMBASE, PsycINFO, and CINAHL databases were searched on April 25, 2019 (Prospero Registration: CRD42019118888). We included peer-reviewed prospective studies which examined risk factors that contributed to recurrent falls in adults aged ≥ 60 years. Using the falls risk classification system of Lord and colleagues, we classified each risk factor into one of the following domains: 1) balance and mobility; 2) environmental; 3) psychological; 4) medical; 5) medication; 6) sensory and neuromuscular; or 7) sociodemographic. We calculated the summary relative risk (RR) for each domain and evaluated the risk of bias and quality of reporting. Twenty-two studies were included in this systematic review and meta-analysis. Four domains predicted recurrent falls: balance and mobility (RR:1.32;95 % CI:[1.10, 1.59]), medication (RR:1.53;95 % CI:[1.11, 2.10]), psychological (RR:1.35;95 % CI:[1.03, 1.78]), and sensory and neuromuscular (RR:1.51;95 % CI:[1.18, 1.92]). Each of these four domains can be viewed as a marker of frailty. The risk of bias was low, and the study quality was high (minimum:19/22). Older adults with markers of frailty are up to 53 % more likely to experience recurrent falls. Strategies that identify and resolve frailty markers should be a frontline approach to preventing recurrent falls.

Smartphone frailty screening: Development of a quantitative early detection method for the frailty syndrome

BACKGROUND

Frailty syndrome in older population generates formidable social cost. The early detection of "prefrail" stage is essential so that interventions could be performed to prevent deterioration. The purpose of this study was to organize appropriate physical performance tests into a computerized early frailty screening platform, called frailty assessment tools (FAT) system, to detect individuals who are in the prefrail stage.

METHODS

Four switches, one distance meter, and one power measure were adopted to build the FAT system that could perform six physical performance tests including single leg standing (SLS), repeated chair rise, timed up and go, self-selected walking speed, functional reach, and grip power. Participants over 65 years old were recruited and classified into three groups according to Fried criteria. The differences in variables between prefrail and robust groups were compared by the χ test, independent samples t test, and Mann-Whitney U test, for nominal variables, normal, and non-normal distributive continuous variables, respectively. The statistically significant level was set at 0.05 (α = 0.05).

RESULTS

Only SLS did not reach significance to distinguish prefrail from robust. Among 35 participants (73.23 ± 5.70 years old), the FAT score predicted that 90.73 ± 19.95% of pre-frail subjects and 15.01 ± 25.25% of robust subjects were in the prefrail stage.

CONCLUSION

The FAT system, which provides results immediately, is an advantageous alternative to traditional manual measurements. The use of the FAT score for predicting the prefrail stage will help to provide early intervention to prevent individuals from progressing into frailty. The FAT system provides a more convenient and comprehensive frailty screening. Using this computerized automatic screening platform, it may be possible to expand the scope of frailty prevention.

Helicobacter pylori Related Diseases and Osteoporotic Fractures (Narrative Review)

Osteoporosis (OP) and osteoporotic fractures (OFs) are common multifactorial and heterogenic disorders of increasing incidence. Helicobacter pylori (H.p.) colonizes the stomach approximately in half of the world's population, causes gastroduodenal diseases and is prevalent in numerous extra-digestive diseases known to be associated with OP/OF. The studies regarding relationship between H.p. infection (HPI) and OP/OFs are inconsistent. The current review summarizes the relevant literature on the potential role of HPI in OP, falls and OFs and highlights the reasons for controversies in the publications. In the first section, after a brief overview of HPI biological features, we analyze the studies evaluating the association of HPI and bone status. The second part includes data on the prevalence of OP/OFs in HPI-induced gastroduodenal diseases (peptic ulcer, chronic/atrophic gastritis and cancer) and the effects of acid-suppressive drugs. In the next section, we discuss the possible contribution of HPI-associated extra-digestive diseases and medications to OP/OF, focusing on conditions affecting both bone homeostasis and predisposing to falls. In the last section, we describe clinical implications of accumulated data on HPI as a co-factor of OP/OF and present a feasible five-step algorithm for OP/OF risk assessment and management in regard to HPI, emphasizing the importance of an integrative (but differentiated) holistic approach. Increased awareness about the consequences of HPI linked to OP/OF can aid early detection and management. Further research on the HPI-OP/OF relationship is needed to close current knowledge gaps and improve clinical management of both OP/OF and HPI-related disorders.

Frailty as a predictor of future falls and disability: a four-year follow-up study of Chinese older adults

BACKGROUND

Frailty, which is defined as aging-related multisystem impairments, can lead to adverse health outcomes. However, evidence for such a connection in Chinese older adults remains lacking. This study examined the association between frailty and future falls and disability among community-dwelling Chinese older adults.

METHODS

Data were obtained from the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study. Participants were aged 60 years and above at baseline in 2011 and completed the follow-up survey in 2015. Outcome measures were future falls, incident disability in activities of daily living (ADLs) and instrumental activities of daily living (IADLs), and worsening performance of ADLs and IADLs. A multivariate logistic regression was conducted to examine the association between frailty phenotype and falls, incident disability, and worsening disability during a four-year period.

RESULTS

We found that frail participants were at increased risk at follow-up for: falls (OR 1.54, 95% CI, 1.14-2.08); developing new ADL difficulties (OR 4.10, 95% CI, 2.79-6.03) and IADL difficulties (OR 3.06, 95% CI, 2.03-4.61); and worsening ADLs performance (OR 2.27, 95% CI, 1.27-4.06), after adjusting for potential confounders. Prefrailty was also significantly associated with future falls, incident disability in ADLs and IADLs, but with a lower magnitude of effect.

CONCLUSIONS

Frailty phenotype is an independent predictor of future falls, incident disability, and worsening performance in ADLs among Chinese older adults. The association suggests the need to pay special attention in caring for frail and prefrail elders and improving individuals' frailty status.

Comparison of the Efficacy and Renal Safety of Bisphosphonate Between Low-Dose/High-Frequency and High-Dose/Low-Frequency Regimens in a Late-Stage Chronic Kidney Disease Rat Model

The efficacy and renal safety of low-dose/high-frequency (LDHF) dosing and high-dose/low-frequency (HDLF) dosing of bisphosphonates (BPs) are comparable in patients with normal kidney function but might be different in patients with late-stage chronic kidney disease (CKD). This study aimed to compare the efficacy and renal safety of two different dosage regimens of a BP, alendronate (ALN), in stage 4 CKD using a rat model. Male, 10-week-old Sprague-Dawley rats were subjected to either 5/6 nephrectomy or sham surgery. The animals received subcutaneous administration of vehicle (daily) or ALN in LDHF dosage regimen (LDHF-ALN: 0.05 mg/kg/day) or HDLF dosage regimen (HDLF-ALN: 0.70 mg/kg/2 weeks). Medications commenced at 20 weeks of age and continued for 10 weeks. Micro-computed tomography, histological analysis, infrared spectroscopic imaging, and serum and urine assays were performed to examine the efficacy and renal safety of the ALN regimens. Both LDHF-ALN and HDLF-ALN increased bone mass, improved micro-structure, and enhanced mechanical properties, without causing further renal impairment in CKD rats. Histologically, however, HDLF-ALN more efficiently suppressed bone turnover, leading to more mineralized trabecular bone, than LDHF-ALN in CKD rats, whereas such differences between LDHF-ALN and HDLF-ALN were not observed in sham rats. Both LDHF-ALN and HDLF-ALN showed therapeutic effects on high bone turnover osteoporosis in CKD stage 4 rats without causing further renal impairment. However, as HDLF-ALN more efficiently suppressed bone turnover than LDHF-ALN in late-stage CKD, HDLF-ALN might be more appropriate than LDHF-ALN for fracture prevention in high bone turnover osteoporosis patients with late-stage CKD.

Validation of "(fr)AGILE": a quick tool to identify multidimensional frailty in the elderly

Background

Several tools have been proposed and validated to operationally define frailty. Recently, the Italian Frailty index (IFi), an Italian modified version of Frailty index, has been validated but its use in clinical practice is limited by long time of administration. Therefore, the aim of this study was to create and validate a quick version of the IFi (AGILE).

Methods

Validation study was performed by administering IFi and AGILE, after a Comprehensive Geriatric Assessment (CGA) in 401 subjects aged 65 or over (77 ± 7 years). AGILE was a 10-items tool created starting from the more predictive items of the four domains of frailty investigated by IFi (mental, physical, socioeconomic and nutritional). AGILE scores were stratified in light, moderate and severe frailty. At 24 months of follow-up, death, disability (taking into account an increase in ADL lost ≥1 from the baseline) and hospitalization were considered. Area under curve (AUC) was evaluated for both IFi and AGILE.

Results

Administration time was 9.5 ± 3.8 min for IFi administered after a CGA, and 2.4 ± 1.2 min for AGILE, regardless of CGA (p < 0.001). With increasing degree of frailty, prevalence of mortality increased progressively from 6.5 to 41.8% and from 9.0 to 33.3%, disability from 16.1 to 64.2% and from 22.1 to 59.8% and hospitalization from 17.2 to 58.7% and from 27.0 to 52.2% with AGILE and IFi, respectively (p = NS). Relative Risk for each unit of increase in AGILE was 56, 44 and 24% for mortality, disability and hospitalization, respectively and was lower for IFi (8, 7 and 4% for mortality, disability and hospitalization, respectively). The AUC was higher in AGILE vs. IFi for mortality (0.729 vs. 0.698), disability (0.715 vs. 0.682) and hospitalization (0.645 vs. 0.630).

Conclusions

Our study shows that AGILE is a rapid and effective tool for screening multidimensional frailty, able to predict mortality, disability and hospitalization, especially useful in care settings that require reliable assessment instruments with short administration time.

Effects of long-term in vivo micro-CT imaging on hallmarks of osteopenia and frailty in aging mice

In vivo micro-CT has already been used to monitor microstructural changes of bone in mice of different ages and in models of age-related diseases such as osteoporosis. However, as aging is accompanied by frailty and subsequent increased sensitivity to external stimuli such as handling and anesthesia, the extent to which longitudinal imaging can be applied in aging studies remains unclear. Consequently, the potential of monitoring individual mice during the entire aging process-from healthy to frail status-has not yet been exploited. In this study, we assessed the effects of long-term in vivo micro-CT imaging-consisting of 11 imaging sessions over 20 weeks-on hallmarks of aging both on a local (i.e., static and dynamic bone morphometry) and systemic (i.e., frailty index (FI) and body weight) level at various stages of the aging process. Furthermore, using a premature aging model (PolgA(D257A/D257A)), we assessed whether these effects differ between genotypes. The 6th caudal vertebrae of 4 groups of mice (PolgA(D257A/D257A) and PolgA(+/+)) were monitored by in vivo micro-CT every 2 weeks. One group was subjected to 11 scans between weeks 20 and 40 of age, whereas the other groups were subjected to 5 scans between weeks 26-34, 32-40 and 40-46, respectively. The long-term monitoring approach showed small but significant changes in the static bone morphometric parameters compared to the other groups. However, no interaction effect between groups and genotype was found, suggesting that PolgA mutation does not render bone more or less susceptible to long-term micro-CT imaging. The differences between groups observed in the static morphometric parameters were less pronounced in the dynamic morphometric parameters. Moreover, the body weight and FI were not affected by more frequent imaging sessions. Finally, we observed that longitudinal designs including baseline measurements at young adult age are more powerful at detecting effects of in vivo micro-CT imaging on hallmarks of aging than cross-sectional comparisons between multiple groups of aged mice subjected to fewer imaging sessions.

Frailty Intervention through Nutrition Education and Exercise (FINE). A Health Promotion Intervention to Prevent Frailty and Improve Frailty Status among Pre-Frail Elderly-A Study Protocol of a Cluster Randomized Controlled Trial

The ageing process has been associated with various geriatric issues including frailty. Without early prevention, frailty may cause multiple adverse outcomes. However, it potentially may be reversed with appropriate interventions. The aim of the study is to assess the effectiveness of nutritional education and exercise intervention to prevent frailty among the elderly. A 3-month, single-blind, two-armed, cluster randomized controlled trial of the frailty intervention program among Malaysian pre-frail elderly will be conducted. A minimum of total 60 eligible respondents from 8 clusters (flats) of Program Perumahan Rakyat (PPR) flats will be recruited and randomized to the intervention and control arm. The intervention group will receive a nutritional education and a low to moderate multi-component exercise program. To date, this is the first intervention study that specifically targets both the degree of frailty and an improvement in the outcomes of frailty using both nutritional education and exercise interventions among Malaysian pre-frail elderly. If the study is shown to be effective, there are major potential benefits to older population in terms of preventing transition to frailty. The findings from this trial will potentially provide valuable evidence and serve as a model for similar future interventions designed for elderly Malaysians in the community.

Osteoporosis in Older Adults

Osteoporosis and osteoporosis-related fractures are common causes of morbidity and mortality in older adults. Healthy adults should be counseled about measures to prevent osteoporosis. Women should be screened for osteoporosis beginning at age 65. Screening for osteoporosis in men should be considered when risk factors are present. Appropriate screening intervals are controversial. Women and men with osteoporosis should be offered pharmacologic therapy. Choice of therapy should be based on safety, cost, convenience, and other patient-related factors. Bisphosphonates are a first-line therapy for many patients with osteoporosis. Other treatments for osteoporosis include denosumab, teriparatide, abaloparatide, romosozumab, and selective estrogen receptor modulators.

Loneliness as a risk factor for frailty transition among older Chinese people

Background

Previous literature has reported that loneliness is a strong predictor of frailty risk. However, less is known about the role of loneliness in frailty transition types. This study aimed to examine whether and how loneliness are related to frailty transition among older Chinese people.

Methods

Our study used participants (aged ≥60 years) from 2008/2009, 2011/2012 and 2014 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Loneliness was assessed by a single question asking how often the respondent feels lonely. The FRAIL Scale was created to measure physical frailty for our study, and frailty was also assessed by a broader definition of the frailty index. Frailty transition as an outcome variable has been designed as two types according to the measurement of frailty.

Results

Greater loneliness at baseline reduced the possibility of remaining in a robust or prefrail physical frailty state after 3 years (OR = 0.78, 95%CI: 0.68–0.91, p < 0.01). Greater loneliness was associated with an increased risk of worsening physical frailty over time: compared with those who had never felt lonely, the odds ratios for people who often felt lonely were 1.19 (95%CI: 1.01–1.41, p < 0.05) after 3 years and 1.34 (95%CI: 1.08–1.66, p < 0.01) after 6 years. The association between loneliness and change in the frailty index differed in the survey periods: loneliness at baseline was found to increase the possibility of participants remaining in frailty (seldom loneliness: OR = 1.78, 95%CI: 1.25–2.55, p < 0.01; often loneliness: OR = 1.74, 95%CI: 1.21–2.50, p < 0.01) after 6 years, but no significance was shown in the 3-year follow up. Additionally, loneliness at baselines was significantly associated with frailty transition at follow up among the male participants. However, a similar association was not observed among the female participants.

Conclusion

Older people with a high level of loneliness tend to be frail in the future, and greater loneliness is related to an increased risk of worsening frailty and remaining frail. Male elderly with a high level of loneliness were more likely to have a worse frailty transition than female elderly in China.

Developing and validating the Community-Oriented Frailty Index (COM-FI)

INTRODUCTION

Methods for measuring frailty over-emphasise physical health, and consensus for a more holistic approach is increasing. However, holistic tools have had mixed success in meeting the validation criteria required of a frailty index. We report on the further development and validation of a Frailty Tool designed for use in the community with a greater emphasis on psychological markers, Holland et al's Community-Oriented Frailty Index (COM-FI).

METHOD

A total of 351 participants aged 58-96 were recruited from Retirement Villages and local communities across the West Midlands of the UK. Participants completed a series of measures designed to assess frailty and outcomes associated with frailty over a 2-year period.

RESULTS

All three candidate items ('polypharmacy', 'exercise frequency', and the Coronary Heart Disease and Diabetes 'joint effect') were incorporated into the tool, and one variable, 'falls' was removed from the index. The revised COM-FI was shown to be valid and met Rockwood's validation criteria (Rockwood et al., 2006), with the exception that in this specific sample there was no significant gender difference and the index did not predict mortality.

DISCUSSION

Overall, the COM-FI is a valid and reliable tool, although the capacity for the COM-FI to predict mortality over a 2-year period remains inconclusive given the small numbers of people at the higher ends of the frailty range. Prediction of need for social care was good, showing the utility of this community based tool.

The dynamics of frailty and change in socio-economic conditions: evidence for the 65+ in Europe

BACKGROUND

The frailty phenotype for older people is defined as an increased vulnerability to stressors, leading to adverse health outcomes. It is acknowledged as a specific precursor of disability besides chronic diseases that allows for some reversibility in the loss of autonomy. Although the literature on the socio-economic determinants of frailty is emerging in cross-sectional settings, little is known about the dynamics of this relationship over time. This article examines the joint evolution of frailty and change in economic conditions for the 65+ in Europe.

METHODS

Individual and longitudinal data from SHARE (Survey on Health, Ageing and Retirement in Europe) over the period 2004-12 has been used. The sample contains 31 044 observations from 12 002 respondents aged 65 or more. A fixed effect Poisson model is estimated in order to control for unobserved individual heterogeneity. Three types of explanative economic variables have been considered in turn: income, wealth and a subjective variable of deprivation.

RESULTS

Our results indicate that individuals with worsening economic conditions (wealth and subjective deprivation) over time simultaneously experience a rapid increase in the frailty symptoms. Results also show that the nature of economic variable does not affect the frailty process in the same way. Subjective measure of deprivation seems to better evaluate the household's financial difficulties than objective measure.

CONCLUSION

From a public policy perspective, these results show that policies fostering economic conditions of the elderly could have a significant impact on frailty and henceforth, could reduce the risks of disability.

Lifestyle Activity Patterns Related to Physical Frailty and Cognitive Impairment in Urban Community-Dwelling Older Adults in Japan

OBJECTIVES

Investigating the lifestyle activity patterns of urban community-dwelling Japanese older adults, focusing on physical frailty and cognitive impairment.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

Participants comprised 8003 older adults (4489 women; mean age: 72.5 years, SD = ±6.1, range 60-95 years) from the National Center for Geriatrics and Gerontology Study of Geriatric Syndromes.

METHODS

Participants reported on their lifestyle activity status, including using public transport, grocery shopping, light exercise, gardening, money management, meeting friends, participating in events, and travel. Several potential confounding variables, such as demographic characteristics, were considered. We assessed their lifestyle activity patterns using a latent class analysis and defined physical frailty by either slow walking speed or poor grip strength. Cognitive impairment was defined by participants exhibiting more than 1 of the following symptoms: poor word list memory, poor attention, reduced executive function, and low processing speed test scores. We also examined the relationship between their lifestyle activity patterns and physical frailty and cognitive impairment.

RESULTS

The overall prevalence of robustness, physical frailty, cognitive impairment, and frailty and cognitive impairment was 54.6%, 21.4%, 13.3%, and 10.7%, respectively. We defined 4 classes using latent class analysis: greater engagement in multidomain activities, lower engagement in going-out activities, lower engagement in cognitive and physical activities, and lower engagement in multidomain activities. Moreover, physical frailty and cognitive impairment were independently associated with lower engagement in going-out activity, lower engagement in cognitive and physical activities, and lower engagement in multidomain activities, after adjusting for covariates.

CONCLUSIONS AND IMPLICATIONS

Considering an older adult's lifestyle activity patterns in their day-to-day practice, clinicians can deliver more older adult-centered care, which in turn might lead to better outcomes in the primary prevention of disease.

Physical Frailty and Fall Risk in Community-Dwelling Older Adults: A Cross-Sectional Study

Introduction

Frailty is a condition in older adults with decreased physical and cognitive performance that can affect health outcomes associated with fracture, disability, and falls. The aim of this study was to compare fall risk with different physical frailty statuses and investigate factors associated with fall risk in community-dwelling older adults.

Methods

The population studied included 367 older adults (mean age = 73.2 years ± 7.0; 237 females (64.6%) and 130 males (35.4%)) who live in Chiang Mai, Thailand. This study was of cross-sectional design. Fried's phenotype was used to screen the physical frailty status. The physiological profile assessment (PPA) was used to screen for fall risk. One-way ANOVA analysis was used to compare the fall risk between the different levels of frailty status. Linear regression analysis was used to assess the association between frailty status and fall risk.

Results

The prevalence of the frailty group was 8.7% and that of the prefrailty group was 76.8%. The three statuses of frailty identified were found to have different levels of risk of falling. The frailty group had a higher fall risk than the nonfrailty group and the prefrailty group. In addition, the nonfrailty group had a lower fall risk than the prefrailty group.

Conclusion

The frailty group had the highest fall risk in this cohort of older adults living in a community-dwelling facility. Therefore, it is important to assess the frailty status among older adults as it can be a predictor for fall risk. This assessment will therefore lead to a reduction in the rate of disability and death in the community.

Caregiving Intensity and Mortality in Older Women, Accounting for Time-Varying and Lagged Caregiver Status: The Caregiver-Study of Osteoporotic Fractures Study

BACKGROUND AND OBJECTIVES

Caregiving is associated with reduced mortality in recent studies. Investigations of caregiving intensity may reveal an underlying mechanism. However, studies of caregiving intensity and mortality have mixed results, perhaps due to imprecise measurement of caregiving intensity, not accounting for healthier persons likely having greater caregiving involvement, or temporal changes in intensity. We examined the relationship between caregiving intensity (based on tasks performed) and mortality, treating intensity and health status as time-varying, and lagging exposure.

RESEARCH DESIGN AND METHODS

Caregiving tasks among 1,069 women in the Caregiver-Study of Osteoporotic Fractures study (35% caregivers) were assessed at 5 interviews conducted between 1999 and 2009. Caregivers were categorized as high intensity if they assisted a person with dressing, transferring, bathing, or toileting; or as low intensity if they assisted with other instrumental or basic activities of daily living (I/ADLs). Alternatively, high intensity was defined as assisting with more than the median number of I/ADL tasks (median-based measure). Mortality was assessed through 2011. Cox proportional hazards models estimated adjusted hazard ratios (aHR) and 95% confidence intervals based on concurrent intensity, and lagging exposure 2 years.

RESULTS

High-intensity caregivers had significantly lower mortality using the median-based measure after lagging exposure (aHR = 0.55, 0.34-0.89). Similar, but not statistically significant associations were observed in non-lagged analyses (aHR = 0.54, 0.29-1.04) and task-specific intensity (aHRs were 0.61 and 0.51). Low-intensity caregivers had similar mortality rates to noncaregivers in all analyses.

DISCUSSION AND IMPLICATIONS

Among older women, high-intensity caregivers had lower mortality rates than noncaregivers. Whether this association extends to other populations merits investigation.

Residential Greenness and Frailty Among Older Adults: A Longitudinal Cohort in China

OBJECTIVES

Frailty is an accumulation of deficits characterized by reduced resilience to stressors and increased vulnerability to adverse outcomes. There is evolving evidence on the health benefits of residential greenness, but little is known about its impact on frailty.

DESIGN

A longitudinal cohort study.

SETTING AND PARTICIPANTS

We included older adults aged ≥65 years from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) with a 12-year follow-up.

METHODS

We assessed residential greenness by calculating the Normalized Difference Vegetation Index (NDVI) in the 500 m radius around participants' residence. We used 39 self-reported health items to construct a frailty index (FI) as a proportion of accumulated deficits. We defined an FI of ≤0.21 as nonfrail and prefrail, and an FI of >0.21 as frail. We used the mixed effects logistic regression models to examine the association between residential greenness and frailty, adjusted for a number of covariates.

RESULTS

We had 16,238 participants, with a mean age of 83.0 years (standard deviation: 11.5). The mean baseline NDVI and FI were 0.40, and 0.12, respectively. Compared to the participants living in the lowest quartile of residential greenness, those in the highest quartile had a 14% [odds ratio (OR): 0.86, 95% confidence interval (CI): 0.77, 0.97] lower odds of frailty. The association was stronger among urban vs rural residents. Additionally, each 0.1-unit increase in annual average NDVI was related to a 2% higher odds of improvement in the frailty status (OR: 1.02, 95% CI: 1.00, 1.04).

CONCLUSIONS AND IMPLICATIONS

Our study suggests that higher levels of residential greenness are related to a lower likelihood of frailty, specifically in urban areas.

Frailty transitions predict healthcare use and Medicare payments in older Mexican Americans: a longitudinal cohort study

BACKGROUND

Little is known regarding the impact of transitions in frailty on healthcare use and payment in older Mexican Americans. We address this gap in knowledge by investigating the effect of early transitions in physical frailty on the use of healthcare services and Medicare payments involving older Mexican Americans.

METHODS

Longitudinal analyses were conducted using the Hispanic Established Populations for the Epidemiological Study of the Elderly (Hispanic-EPESE) survey data from five Southwest states linked to the Medicare claims files from the Centers for Medicare and Medicaid Services. Seven hundred and eighty-eight community-dwelling Mexican Americans 72 years and older in 2000/01 were studied. We used a modified Frailty Phenotype (unintentional weight loss, weakness, self-reported exhaustion and slow walking speed) to classify frailty status (non-frail, pre-frail or frail). Each participant was placed into one of 5 frailty transition groups: 1) remain non-frail, 2) remain pre-frail, 3) remain frail, 4) improve (pre-frail to non-frail, frail to non-frail, frail to pre-frail) and 5) worse (non-frail to pre-frail, non-frail to frail, pre-frail to frail). The outcomes for the one-year follow-up period (2000-2001) were: (a) healthcare use (hospitalization, emergency room [ER] admission and physician visit); and (b) Medicare payments (total payment and outpatient payment).

RESULTS

Mean age was 78.8 (SD = 5.1) years and 60.3% were female in 1998/99. Males who remained pre-frail (Odds Ratio [OR] = 3.49, 1.13-10.8, remained frail OR = 6.92, 1.61-29.7) and transitioned to worse frail status (OR = 4.49, 1.74-11.6) had significantly higher hospitalization risk compared to individuals who remained non-frail. Males in the 'worsened' groups, and females in the 'improved' groups, had significantly higher Medicare payments than individuals who remained non-frail (Cost Ratio [CR] = 2.00, 1.30-3.09; CR = 1.53, 1.12-2.09, respectively].

CONCLUSIONS

Healthcare use and Medicare payments differed by frailty transition status. The differences varied by sex. Research is necessary to elucidate the relationship between frailty transitions and outcomes, sex difference and Medicare payment for older Mexican Americans living in the community.

Psychometric analysis of the Arabic (Saudi) Tilburg Frailty Indicator among Saudi community-dwelling older adults

BACKGROUND

Frailty is a common geriatric syndrome that can be screened using validated questionnaires. A commonly used assessment is the Tilburg Frailty Indicator (TFI), containing fifteen self-reported questions about components of frailty, with scores ranging from zero to fifteen (higher scores representing increased frailty and a cutoff score of greater than five used to diagnose frailty). Despite its widespread use, the TFI is not commonly used in Arabic-speaking countries, and there is an overall lack of Arabic-translated questionnaires to adequately detect and measure frailty for older adults in Saudi Arabia.

OBJECTIVES

To translate and cross-culturally adapt the Tilburg Frailty Indicator (TFI) specifically for use with the Saudi population, and to examine reliability and construct validity among adults in senior-living facilities in Saudi Arabia.

METHODS

A total of 84 community-dwelling older adults were enrolled (mean age = 72 ± 4.7 years). The translation and cross-cultural adaptation of the TFI from English to Arabic was performed using standardized guidelines. Test-retest reliability and internal consistency were examined in two visits, spaced one-week apart. Construct validity of the TFI against other measurements related to frailty was examined. The physical domain for TFI was validated against the Short Physical Performance Battery (SPPB), the timed Up and Go Test (TUG), and gait speed (as part of the SPPB). The psychological domains were validated against the Patient Health Questionnaire, and the social domains were validated against the social domain scores from the WHOQOL-BREF.

RESULTS

The internal consistency of the TFI with the overall KR-20 was 0.70. For the domain scores KR-20 was 0.68 for the physical, 0.57 for the psychological, and 0.42 for the social. The KR-20 after deletion of each item correlations ranged from 0.66 to 0.72. For the test-retest reliability with one-week interval, the ICC was 0.86 (95 % CI = 0.67-0.94). The Arabic TFI showed statistically significant association with other measurements related to frailty.

CONCLUSION

This study found that the translated Arabic (Saudi) TFI is a valid and reliable instrument in assessing the frailty among Saudi community-dwelling older adults. Our results suggest that the use of this Arabic-translated TFI for clinical screening of frailty in any primary health setting may aid continued understanding for the validity of this instrument and help provide a quantitative diagnostic tool for the prevention and treatment of frailty.
